NOTE 3. REGULATORY MATTERS FLORIDA WATER 1995 RATE CASE. Florida Water requested an $18.1 million annual rate increase in June 1995 for all water and wastewater customers of Florida Water regulated by the FPSC. In October 1996 the FPSC issued its final order approving an $11.1 million annual increase. The new rates were implemented in September 1996. In November 1996 Florida Water filed with the Florida First District Court of Appeals (Court of Appeals) an appeal of the FPSC's final order seeking judicial review of issues relating to the amount of investment in utility facilities recoverable in rates from current customers. Other parties to the rate case also filed appeals. In the course of the appeals process, the FPSC reconsidered an issue in its initial decision and, in June 1997, allowed Florida Water to resume collecting approximately $1 million, on an annual basis, in new customer fees. On June 10, 1998 the Court of Appeals ruled in Florida Water's favor on all material issues appealed by Florida Water and remanded the matter back to the FPSC for action consistent with the Court's order. The Court of Appeals also overturned its decision in Florida Water's 1991 Rate Case which had required a "functional relationship" between service areas as a precondition to implementation of uniform rates. On December 15, 1998 the FPSC granted Florida Water an additional annual revenue increase of approximately $1.2 million related to several of the issues reversed by the Court of Appeals, and permitted collection of approximately $2.4 million in surcharges to reimburse Florida Water for revenue (plus interest) wrongfully denied in the FPSC's October 1996 order. Florida Water began collecting the new rates in January 1999. Intervenors protested the surcharge allocation methodology. As a result collection of the surcharges is delayed and interest accumulates until the FPSC approves a methodology. The FPSC reopened the record on two remaining issues on remand from the Court of Appeals regarding the amount of investment in utility facilities recoverable in rates from current customers. Hearings have been set for January 2000 and pre-filed testimony is due in November 1999. On June 14, 1999 the Company filed a motion seeking approval of an offer of settlement. The offer would increase annual revenue by approximately $1 million; place accumulated surcharges, including interest accrued through August 1, 1999, into a regulatory asset recoverable in rate base in the next ratemaking proceeding; and, provide a three-year moratorium on the initiation of rate cases by the Company or the FPSC, exclusive of index filings. The motion is scheduled to be heard by the FPSC on August 23, 1999. The Company is unable to predict the timing or outcome of these proceedings. 1991 RATE CASE REFUNDS. In 1995 the 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 on January 26, 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 26, 1998 order, the FPSC required Florida Water to refund $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 (see Florida Water 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 26, 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 on May 22, 1998. Upon issuance of the June 10, 1998 opinion of the Court of Appeals with respect to Florida Water's 1995 Rate Case (see 1995 Rate Case) in which the court reversed its previous ruling that the FPSC was without authority to order uniform rates, customer groups supporting the FPSC's January 1998 order filed -6-

NOTE 3. REGULATORY MATTERS - CONTINUED a motion with the Court of Appeals seeking dismissal of the appeal by customer groups seeking refunds. Customers seeking refunds filed amended briefs on September 14, 1998. No provision for refund has been recorded. The Company is unable to predict the timing or outcome of the appeals process. ELECTRIC MPUC ORDERS. On July 27, 1999 the MPUC issued an order approving the Company's Conservation Improvement Program (CIP) filing, except for the recovery of lost margins which was denied. The annual filing requested approval for a 1998 year end CIP tracker account balance (deferred charge) of $18.9 million; recovery in 1999 of $3.5 million of 1998 lost margins; and a continuation of the 2.75 percent billing adjustment factor. The MPUC's primary rationale for denial of lost margin recovery was that in 1998 Electric Operations earned in excess of its allowed return on equity. In a companion order, the MPUC opened an investigation into the reasonableness of Minnesota Power's rates. The Company is required to file within 60 days a report evaluating 1998 electric earnings and explain why current rates are just and reasonable. The Company intends to request reconsideration of both orders. The Company is unable to predict the outcome of these matters. NOTE 4. ACQUISITIONS PALM COAST UTILITIES CORPORATION.

The 70 acre facility has six auction lanes. The purchase of the Vancouver auction facility is a major component of the Company's Canadian growth strategy. -7-

NOTE 5. INVESTMENT IN CAPITAL RE On May 27, 1999 Capital Re announced an agreement by which it will be acquired by ACE Limited (ACE), a publicly traded company listed on the New York Stock Exchange under the symbol ACL. Under the agreement, Capital Re shareholders will receive 0.6 shares of ACE for each share of Capital Re, subject to a maximum value to Capital Re shareholders of $22 per share. The Company owns 7.3 million shares, or 19.9 percent, of Capital Re. Subject to the maximum exchange value, upon closing (which is expected to occur in the second half of 1999) the Company will own approximately 4.4 million shares, or 2 percent of the outstanding shares, of ACE. The Company has agreed to vote in favor of the merger and not to dispose of the ACE shares received for 180 days following the closing date, except in a single private sale of all or substantially all of the original shares the Company will receive. The quarter and six months ended June 30, 1999 included a $24.1 million non-cash charge, which reflected the estimated valuation of this transaction at June 30, 1999. The final valuation of this transaction will be based on the ACE share price at closing, and may differ from the amount recognized in the second quarter of 1999. The charge will be recouped to the extent ACE shares appreciate over time. The ultimate realized gain or loss on the transaction will occur when the Company sells the ACE shares. The Company no longer accounts for its investment in Capital Re using the equity method. NOTE 6.

NOTE 8. SQUARE BUTTE PURCHASED POWER CONTRACT The Company has had a power purchase agreement with Square Butte since 1977 which has provided a long-term supply of low-cost energy to customers in the Company's service territory and enabled 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. In May 1998 the Company and Square Butte entered into a new power purchase agreement (1998 Agreement), replacing the 1977 agreement. The Company extended by 20 years, to January 1, 2027, its access to Square Butte's low-cost electricity and eliminated its unconditional obligation for all of Square Butte's costs if not paid by Square Butte when due. The 1998 Agreement was reached in conjunction with the termination of Square Butte's previous leveraged lease financing arrangement and refinancing of associated debt. Similar to the previous agreement, the Company is initially entitled to approximately 71 percent of the Unit's output under the 1998 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. Under the 1998 Agreement, 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. Under the 1977 agreement the Company was unconditionally obligated to pay all of Square Butte's costs, if not paid by Square Butte when due. Square Butte's fixed costs consist primarily of debt service. At June 30, 1999 Square Butte had total debt outstanding of $343.4 million. Total annual debt service for Square Butte is expected to be approximately $36 million in each of the years 1999 through 2002 and $23 million in 2003. 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. -9-

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS MINNESOTA POWER is a broadly diversified service company with operations in four business segments: (1) Electric Operations, which include electric and gas services, coal mining and telecommunications; (2) Water Services, which include water and wastewater services; (3) Automotive Services, which include a network of vehicle auctions, a finance company, an auto transport company and a vehicle remarketing company; 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 allocated to any one business segment. CONSOLIDATED OVERVIEW Significant growth in the Company's Water Services and Automotive Services segments contributed to higher operating results in 1999. For the quarter and six months ended June 30, 1999, the Company reported a $24.1 million non-cash charge associated with the Company's investment in Capital Re. Excluding the non-cash charge, net income for the quarter and six months ended June 30, 1999 increased 14 percent over 1998. Excluding the non-cash charge, earnings per share were $0.38 for the second quarter of 1999, an increase of 6 percent over the prior year period ($0.68 per share for the six months ended June 30, 1999, 5 percent over the prior year period). Earnings per share in 1999 reflected the impact of the additional 4.2 million shares of Common Stock issued by the Company in an underwritten public offering in September 1998.

NET INCOME The following net income discussion summarizes significant events for the quarter and six months ended June 30, 1999. Electric Operations reflected reductions in sales to large industrial customers in 1999. Margins from bulk electric power sales were also lower when compared to margins resulting from the strong market in 1998 created by extremely hot weather in June. Water Services generated higher net income in 1999 due to increased consumption as a result of drier weather conditions and additional customers from the PCUC acquisition. Consumption in the first quarter of 1998 was adversely impacted by record rainfall during that period. The 1999 results of Water Services also included increased rates approved by the FPSC in December 1998. Automotive Services showed significant growth during 1999. The number of vehicles offered for sale at ADESA auction facilities increased 10 percent over the second quarter of 1998 (13 percent over the six months ended June 30, 1998). Increased financing activity and the maturing of loan production offices that opened in 1998 at AFC also contributed to higher net income from Automotive Services. Investments reported lower net income in 1999 primarily due to a $24.1 million non-cash charge that reflected the estimated valuation of the transaction between Capital Re and ACE at June 30, 1999. On May 27, 1999 Capital Re announced an agreement by which it will be acquired by ACE Limited (ACE), a publicly traded company listed on the New York Stock Exchange under the symbol ACL. Under the agreement, Capital Re shareholders will receive 0.6 shares of ACE for each share of Capital Re, subject to a maximum value to Capital Re shareholders of $22 per share. The Company owns 7.3 million shares, or 19.9 percent, of Capital Re. Subject to the maximum exchange value upon closing (which is expected to occur in the second half of 1999), the Company will own approximately 4.4 million shares, or 2 percent of the outstanding shares, of ACE. The Company has agreed to vote in favor of the merger and not to dispose of the ACE shares received for 180 days following the closing date, except in a single private sale of all or substantially all of the original shares the Company will receive. The final valuation of this transaction will be based on the ACE share price at closing, and may differ from the amount recognized in the second quarter of 1999. The charge will be recouped to the extent ACE shares appreciate over time. The ultimate realized gain or loss on the transaction will occur when the Company sells the ACE shares. The Company no longer accounts for its investment in Capital Re using the equity method. Investments also reflected lower net income from Portfolio and Reinsurance because of stock market volatility affecting returns from short-term investments during the first quarter of 1999 and a loss reserve established by Capital Re for reinsurance of securities issued by CFS. CFS is under investigation by the Securities and Exchange Commission and the Oklahoma Securities Commission for allegations of irregularities relating to the CFS issued securities. CFS filed for Chapter 11 bankruptcy protection in December 1998. In addition, 1998 net income included dividend income received from a venture capital investment and five large bulk land sales by Real Estate Operations. -11-

COMPARISON OF THE QUARTERS ENDED JUNE 30, 1999 AND 1998 OPERATING REVENUE Electric Operations operating revenue was $5.4 million lower in 1999 primarily due to a 4 percent reduction in total kilowatthour sales and less demand revenue from large power customers. Decreased taconite production, paper manufacturing and pipeline usage reduced revenue from large industrial customers in 1999. Revenue from electric sales to taconite customers accounted for 14 percent of consolidated operating revenue in 1999 (16 percent in 1998). Electric sales to paper and pulp mills accounted for 5 percent of consolidated operating revenue in 1999 (6 percent in 1998). Sales to other power suppliers and marketers accounted for 8 percent of consolidated operating revenue in both 1999 and 1998. Water Services operating revenue was $4.9 million higher in 1999, with $3.5 million of the increase coming from PCUC which was purchased in January 1999. The remainder of the increase resulted from higher rates approved by the FPSC in December 1998 and more consumption due to drier weather conditions in 1999. Overall consumption increased 16 percent in 1999. Automotive Services operating revenue was $19.2 million higher in 1999 due to stronger sales at ADESA auction facilities, and increased financing activity and the maturing of loan production offices opened in 1998 at AFC. ADESA offered for sale on consignment 428,000 vehicles (388,000 in 1998) at its 29 auction facilities in 1999 (28 in 1998). In 1999 financial results for ADESA auctions included a full three months of operations from three vehicle auctions acquired in late April and May 1998, and two months of operations from a vehicle auction acquired in late April 1999. AFC financed approximately 174,000 vehicles (133,000 in 1998) through its 84 loan production offices in 1999 (63 in 1998). AFC financial results in 1999 included a full three months of operations from the 26 loan production offices opened at ADT auctions. Only six of these offices were open as of June 30, 1998. Investments operating revenue was $8.7 million lower in 1999. Portfolio and Reinsurance operating revenue was $0.7 million higher in 1999 due to a larger portfolio balance. The Company's securities portfolio, excluding Capital Re shares, earned an annualized after-tax return of 6.8 percent in 1999 (8.5 percent in 1998). Real Estate Operations operating revenue was $9.4 million lower in 1999 because 1998 included two large sales at Palm Coast and the sale of a partnership interest in a development at Lehigh. Combined, the three sales contributed $6.4 million to revenue in 1998. The remainder of the decrease was due to normal fluctuations in Florida real estate sales. OPERATING EXPENSES Electric Operations operating expenses were $3.8 million lower in 1999 primarily due to reductions in fuel and purchased power expenses. Operating expenses were also lower in 1999 because the amortization of an early retirement program was completed in July 1998. Water Services operating expenses were $3.0 million higher in 1999 due to inclusion of PCUC operations. Automotive Services operating expenses were $14.4 million higher in 1999 primarily due to increased sales activity at the auction facilities and the floorplan financing business. Additional expenses associated with more auction facilities and loan production offices also contributed to higher expenses in 1999. Investments operating expenses were $4.0 million lower in 1999 primarily due to fewer sales by Real Estate Operations. INCOME (LOSS) FROM EQUITY INVESTMENTS - NET OF TAX Income (loss) from equity investments - net of tax was $22.8 million lower in 1999 due to a $24.1 million non-cash charge that reflected the estimated valuation of the transaction between Capital Re and ACE at June 30, 1999. -12-

COMPARISON OF THE SIX MONTHS ENDED JUNE 30, 1999 AND 1998 OPERATING REVENUE Electric Operations operating revenue was $7.3 million lower in 1999 primarily due to a 4 percent reduction in total kilowatthour sales and less demand revenue from large power customers. Decreased taconite production, paper manufacturing and pipeline usage reduced revenue from large industrial customers in 1999. Revenue from residential and commercial customers was higher in 1999 because the winter weather in Northern Minnesota and Wisconsin was colder than in 1998. Sales to other power suppliers in 1999 were about the same as in 1998. Revenue from electric sales to taconite customers accounted for 15 percent of consolidated operating revenue in 1999 (16 percent in 1998). Electric sales to paper and pulp mills accounted for 5 percent of consolidated operating revenue in 1999 (6 percent in 1998). Sales to other power suppliers and marketers accounted for 7 percent of consolidated operating revenue in both 1999 and 1998. Water Services operating revenue was $8.6 million higher in 1999, with $5.4 million of the increase coming from PCUC which was purchased in January 1999. The remainder of the increase resulted from higher rates approved by the FPSC in December 1998 and more consumption due to drier weather conditions in 1999. Overall consumption increased 21 percent in 1999. In 1998 overall consumption was lower than normal due to record rainfall during that period. Automotive Services operating revenue was $39.3 million higher in 1999 due to stronger sales at ADESA auction facilities, and increased financing activity and the maturing of loan production offices opened in 1998 at AFC. ADESA offered for sale on consignment 824,000 vehicles (728,000 in 1998) at its 29 auction facilities in 1999 (28 in 1998). In 1999 ADESA auction financial results included a full six months of operations from three vehicle auctions acquired in late April and May 1998, and two months of operations from a vehicle auction acquired in late April 1999. AFC financed approximately 323,000 vehicles (253,000 in 1998) through its 84 loan production offices in 1999 (63 in 1998). AFC financial results in 1999 included a full six months of operations from the 26 loan production offices opened at ADT auctions. Only six of these offices were open as of June 30, 1998. Investments operating revenue was $19.7 million lower in 1999. Portfolio and Reinsurance operating revenue was $5.8 million lower in 1999 due to stock market volatility affecting returns from short-term investments. The Company's securities portfolio, excluding Capital Re shares, earned an annualized after-tax return of 3.3 percent in 1999 (6.1 percent in 1998). Also, revenue in 1998 included $3.9 million of dividend income received from a venture capital investment. Real Estate Operations operating revenue was $13.9 million lower in 1999 because 1998 included four large sales at Palm Coast and the sale of a partnership interest in a development at Lehigh. Combined, the five sales contributed $11.5 million to revenue in 1998. The remainder of the decrease was due to normal fluctuations in Florida real estate sales. OPERATING EXPENSES Electric Operations operating expenses were $8.0 million lower in 1999 primarily due to a reduction in purchased power expense. Operating expenses were also lower in 1999 because the amortization of an early retirement program was completed in July 1998. Water Services operating expenses were $4.9 million higher in 1999 due to inclusion of PCUC operations. Automotive Services operating expenses were $28.0 million higher in 1999 primarily due to increased sales activity at the auction facilities and the floorplan financing business. Additional expenses associated with more auction facilities and loan production offices also contributed to higher expenses in 1999. Investments operating expenses were $5.8 million lower in 1999 primarily due to fewer sales by Real Estate Operations. -13-

Corporate Charges operating expenses were $7.5 million lower in 1999. The decrease is partially attributed to less interest expense in 1999 because of smaller commercial paper balances. Also, interest expense in 1998 reflected a settlement with the Internal Revenue Service on tax issues relating to prior years. As a result of the settlement, in the first quarter of 1998 amounts previously accrued as income tax expense were reversed and recorded as interest expense. There was no impact on consolidated net income from this transaction. INCOME (LOSS) FROM EQUITY INVESTMENTS - NET OF TAX Income (loss) from equity investments - net of tax was $21.5 million lower in 1999 due to a $24.1 million non-cash charge that reflected the estimated valuation of the transaction between Capital Re and ACE at June 30, 1999. Also included in 1999 is a $1.7 million loss reserve established by Capital Re for reinsurance of securities issued by CFS. OUTLOOK ELECTRIC OPERATIONS. On July 27, 1999 the MPUC issued an order approving the Company's CIP filing, except for the recovery of lost margins which was denied. The annual filing requested approval for a 1998 year end CIP tracker account balance (deferred charge) of $18.9 million; recovery in 1999 of $3.5 million of 1998 lost margins; and a continuation of the 2.75 percent billing adjustment factor. The MPUC's primary rationale for denial of lost margin recovery was that in 1998 Electric Operations earned in excess of its allowed return on equity. In a companion order, the MPUC opened an investigation into the reasonableness of Minnesota Power's rates. The Company is required to file within 60 days a report evaluating 1998 electric earnings and explain why current rates are just and reasonable. The Company intends to request reconsideration of both orders. The Company is unable to predict the outcome of these matters. LIQUIDITY AND FINANCIAL POSITION CASH FLOW ACTIVITIES. Cash flow from operations during the six months ended June 30, 1999 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, 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 9 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 made by vehicle purchasers. However, ADESA uses 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 uses 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 $225.0 million, to third party purchasers under an agreement which expires at the end of 2001. At June 30, 1999 AFC had sold $291.5 million of finance receivables to this subsidiary ($202.9 million at December 31, 1998). Third party purchasers had purchased an undivided interest in finance receivables of $211.0 million from this subsidiary at June 30, 1999 ($170.0 million at December 31, 1998). Proceeds from the sale of the receivables were used to repay borrowings from the Company and fund vehicle inventory purchases for AFC's customers. -14-

Significant changes in accounts receivable and accounts payable balances at June 30, 1999 compared to December 31, 1998 were due to increased sales activity by 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. Notes payable increased temporarily to finance Automotive Services' cash requirements due to significant auction sales and financing growth. The Company also used the temporary increase in notes payable and proceeds from the September 1998 issuance of Common Stock to fund the January 1999 purchase of PCUC. Florida Water purchased the assets of PCUC from ITT Industries, Inc. for $16.8 million plus $1,000 per new water connection for an eight-year period. The Company estimates the present value of these future water connections to be $5.1 million. On April 30, 1999 ADESA acquired Des Moines Auto Auction located in Des Moines, Iowa. The Company funded this transaction with internally generated funds. On June 17, 1999 Heater acquired the assets of Mid South of Sherills Ford, North Carolina for $9 million. The Company funded this transaction with internally generated funds and proceeds from a long-term revolving line of credit. On June 30, 1999 MP Real Estate purchased, for $36.2 million, certain real estate properties located in Cape Coral, Florida, from a subsidiary of Avatar Holdings Inc. The Company funded this transaction with internally generated funds and proceeds from a long-term revolving line of credit. CAPITAL REQUIREMENTS. Consolidated capital expenditures for the six months ended June 30, 1999 totaled $42.7 million ($33.0 million in 1998). Expenditures for 1999 included $20.9 million for Electric Operations, $9.3 million for Water Services and $12.5 million for Automotive Services. Internally generated funds and proceeds from the September 1998 issuance of Common Stock 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 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. YEAR 2000. The Year 2000 issue relates to computer systems that recognize the year in a date field using only the last two digits. Unless corrected, the Year 2000 may be interpreted as 1900, causing errors or shutdowns in computer systems which may, in turn, disrupt operations. STATE OF READINESS. The Company has been addressing the Year 2000 issue for over five years. In the ordinary course of business, it has replaced, or is in the process of replacing, many of its major computer systems with new systems that have been designed to be Year 2000 compliant. These updated systems handle critical aspects of the Company's operations, including energy management and generation control for Electric Operations, and customer information and financial management Company-wide. Each of the business segments has its own Year 2000 plan, which has been reviewed and is being monitored by a corporate-level Year 2000 Risk Assessment Team. The Company's plan for Year 2000 readiness involves four phases: inventory, evaluation, remediation and contingency planning. Testing is an ongoing and integral part of the evaluation, remediation and contingency planning phases. INVENTORY. Each business segment has performed an extensive inventory of its information technology systems and other systems that use embedded microprocessors (collectively, "Systems"). The business processes supported by each System have been prioritized based on the degree of impact business operations would encounter if the System were disrupted. -15-

The inventory phase also includes identifying third parties with whom the Company has material relationships. The degree to which each business segment depends on third party support varies. Water Services, Automotive Services and Real Estate Operations have identified minimal risk in most areas. Where a third party is critical to a business process, efforts have been initiated to obtain Year 2000 compliance information to identify the degree of risk exposure the Company may encounter. Electric Operations is working with its large power customers to share Year 2000 information and determine their readiness. In addition, Electric Operations is working with its fuel and transportation providers in an effort to ensure adequate supplies of fuel. The internal inventory phase was substantially completed in June 1998. Regular contact with third parties with whom the Company has material relationships will continue throughout 1999. EVALUATION. This phase involves computer program code review and testing, vendor contacts, System testing and fully-integrated System testing where practical. The objective of this phase is to develop and update the remediation plan. Some Systems, upon inspection, are determined to be non-compliant and are immediately placed on the remediation schedule. Some Systems require testing to determine compliance status. The evaluation phase was substantially complete in February 1999. REMEDIATION. In this phase each System is either fixed, replaced or removed. Critical Systems fixed or replaced are tested again for Year 2000 readiness. The electric industry is unique in its reliance on the integrity of the power pool grid to support and maintain reliable, efficient operations. Preparation for the Year 2000 by Electric Operations is linked to the Year 2000 compliance efforts of other utilities as well as to those of its major customers whose loads support the integrity of the power pool grid. Electric Operations is coordinating its Year 2000 efforts with the plans established by the North American Electric Reliability Council (NERC) under the direction of the U.S. Department of Energy and is also working with the MAPP Year 2000 Task Force and a utility industry consortium to obtain and share utility-specific Year 2000 compliance information. The Company estimates that as of August 6, 1999 the remediation phase for mission-critical systems within Electric Operations is 95 percent complete. As defined by NERC, mission-critical systems are those systems that could be related to the loss of a 50-megawatt or larger generation source, the loss of a transmission facility or the interruption of system load. With the exception of certain systems reserved for final integrated testing during scheduled maintenance outages at certain Company generating units at the Boswell Energy Center in the second half of 1999, the Company's mission-critical systems used to produce, deliver and transmit electricity are ready for date changes associated with Year 2000. The Company estimates that as of August 6, 1999 the remediation phase for all business segment systems is approximately 83 percent complete based on the number of systems remediated. The bulk of the remaining systems are support systems within Electric Operations that are not critical to daily operations. The remediation phase for the Company's other business segments was substantially complete in June 1999. CONTINGENCY PLANNING. Each business segment has developed contingency plans designed to continue critical processes in the event the Company experiences Year 2000 disruptions despite remediation and testing. These plans include establishment of internal communications, securing adequate on-site supplies of certain critical materials and staffing for key Year 2000 dates. Contingency plans will also be tested when appropriate. Some contingency plans have already undergone testing. The Company successfully participated in the April 9, 1999 NERC drill which tested inter and intra backup communications for the scenario that assumed 10 percent of voice and data communications had failed. The Company plans to participate in the September 1999 NERC drill which will be a dress rehearsal for the millennium rollover. As of August 6, 1999 the Company estimates the contingency planning phase is approximately 87 percent complete. -16-

COSTS. In the ordinary course of business over the last five years, the Company has replaced major business and operating computer systems. These systems should require minimal remediation efforts because of their recent implementation. Formal Year 2000 readiness plans were established in March 1998. Since that time, the Company has incurred $3 million in expenses primarily for labor associated with inventory, evaluation and remediation efforts. The Company estimates its remaining costs to prepare for the Year 2000 will be approximately $2 million, the majority of which are non-labor costs that will be incurred during the remainder of 1999. Funds to address Year 2000 issues have been provided for in the Company's existing budgets. These costs include the assignment of existing personnel to Year 2000 projects, maintenance and repair expenses, and capitalized improvements. To date no critical projects have been deferred because of Year 2000 issues. The Company does not anticipate that its costs associated with Year 2000 readiness will materially impact the Company's earnings in any year. RISKS. Based upon information to date, the Company believes that, in the most reasonably likely worst-case scenario, Year 2000 issues could result in abnormal operating conditions, such as short-term interruption of generation, transmission and distribution functions within Electric Operations, as well as Company-wide loss of system monitoring and control functions, and loss of voice communications. These conditions, along with power outages due to possible instability of regional electric transmission grids, could result in temporary interruption of service to customers. The Company does not believe the overall impact of this scenario will have a material impact on its financial condition or operations due to the anticipated short-term nature of interruptions. ---------------------------- 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. 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, with utilities being the largest industry sector. Investments held for an indefinite period of time are classified as available-for-sale securities and also recorded at fair value. The available-for-sale securities portfolio consists primarily of the preferred stock of utilities and financial institutions with investment grade debt ratings and Capital Re shares. (See Note 5 to the consolidated financial statements in Item 1 of this quarterly report on Form 10-Q.) In strategies designed to reduce market risks, the Company sells common stock short and enters into short sales of treasury futures contracts. Selling common stock short is intended to reduce price risks associated with securities in the Company's trading securities portfolio. The stock sold short consists primarily of the stock of companies in similar industries. Treasury futures are used as a hedge to reduce interest rate risks associated with holding fixed dividend preferred stocks included in the Company's available-for-sale securities portfolio. Generally, treasury futures contracts mature in 90 days.

(b) The notional fair value of outstanding sales of treasury futures contracts was $9.3 million, which represented 80 contracts with a notional basis of $9.4 million. (c) Securities in a grantor trust established to fund certain employee benefits. -17-

ITEM 5. OTHER INFORMATION Reference is made to the Company's 1998 Form 10-K for background information on the following updates. Unless otherwise indicated, cited references are to the Company's 1998 Form 10-K. Ref. Page 2. - Eighth Paragraph Ref. Page 25. - Tenth Paragraph Ref. 10-Q for the quarter ended March 31, 1999 Page 13. - Fourth and Fifth Paragraphs Steel imports continue to be a critical issue facing American steel producers. Total imports for the first five months of 1999 are running slightly below the record levels of 1998. The surge of imported steel in recent years continues to depress average prices for steel mill products. First quarter prices for 1999 are about 27 percent below the same period in 1998. First quarter steel shipments from American mills are 10 percent lower this year compared to the same period in 1998, with capacity utilization also down compared to last year. In 1998 the United States imported a record 42 million tons of steel, which represented an 83 percent increase over the 23 million ton average for the previous eight years (1990-1997). The continued lower worldwide demand for steel produced in the United States is likely to have an adverse affect on northern Minnesota's taconite producers and the economy of northern Minnesota. The Company is unable to predict the eventual impact of this issue on the Company's Electric Operations. Ref. Page 3. - First Full Paragraph Ref. Page 25. - Eleventh Paragraph Six of the seven taconite producers in Minnesota have collective bargaining agreements with the United Steel Workers of America (USWA). These agreements expire in August 1999. Tentative five-year collective bargaining agreements have been reached with five of the six USWA taconite producers. Contract negotiations with the sixth taconite producer have been put on hold pending the outcome of acquisition discussions with another company. Ref. Page 6. - Seventh Full Paragraph Ref. Page 25. - Insert after Eleventh Paragraph Ref. 10-Q for the quarter ended March 31, 1999 Page 14. - Fifth Paragraph On July 27, 1999 the MPUC issued an order approving the Company's CIP filing, except for the recovery of lost margins which was denied. The annual filing requested approval for a 1998 year end CIP tracker account balance (deferred charge) of $18.9 million; recovery in 1999 of $3.5 million of 1998 lost margins; and a continuation of the 2.75 percent billing adjustment factor. The MPUC's primary rationale for denial of lost margin recovery was that in 1998 Electric Operations earned in excess of its allowed return on equity. In a companion order, the MPUC opened an investigation into the reasonableness of Minnesota Power's rates. The Company is required to file within 60 days a report evaluating 1998 electric earnings and explain why current rates are just and reasonable. The Company intends to request reconsideration of both orders. The Company is unable to predict the outcome of these matters. Ref. Page 9. - National Pollutant Discharge Elimination System Permits Table Ref. 10-Q for the quarter ended March 31, 1999 Page 15. - First Paragraph The Company anticipates the Minnesota Pollution Control Agency will issue new National Pollutant Discharge Elimination System Permits (NPDES) for the Boswell Energy Center in the third quarter of 1999 and the M.L. Hibbard Station in the fourth quarter of 1999. A new NPDES permit for the Laskin Energy Center (Laskin) was issued effective April 27, 1999 and has an expiration date of February 28, 2004. As expected the Laskin permit contains a schedule of compliance requiring the construction of a new ash disposal pond by December 31, 2000. The Company expects to spend approximately $3.3 million in 1999 and another $3.3 million in 2000 to construct the Laskin ash disposal pond. -19-

Page 25. - Twelfth Paragraph Ref. 10-Q for the quarter ended March 31, 1999, Page 15. - Second Paragraph On June 17, 1999 Heater acquired the assets of Mid South located in Sherills Ford, North Carolina for $9 million. The acquisition was accounted for using the purchase method. With the acquisition of Mid South, which serves approximately 12,000 customers, Heater became the largest investor-owned water utility in North Carolina serving almost 45,000 customers in 29 counties. Ref. Page 10. - Seventh Full Paragraph 1995 RATE CASE. The FPSC reopened the record on two remaining issues on remand from the Florida First District Court of Appeals regarding the amount of investment in utility facilities recoverable in rates from current customers. Hearings have been set for January 2000 and pre-filed testimony is due in November 1999. On June 14, 1999 the Company filed a motion seeking approval of an offer of settlement. The offer would increase annual revenue by approximately $1 million; place accumulated surcharges, including interest accrued through August 1, 1999, into a regulatory asset recoverable in rate base in the next ratemaking proceeding; and, provide a three-year moratorium on the initiation of rate cases by the Company or the FPSC, exclusive of index filings. The motion is scheduled to be heard by the FPSC on August 23, 1999. The Company is unable to predict the timing or outcome of these proceedings. ITEM 6.
