On June 30, 1995 Minnesota Power sold its interest in a paper and pulp business to Consolidated Papers, Inc.
-3- ELECTRIC OPERATIONS Electric Operations generate, transmit, distribute and market electricity. Minnesota Power provides electricity to 123,000 customers in northeastern Minnesota. MPEX, a division of Minnesota Power, is an expansion of the Company's inter-utility marketing group which has been a buyer and seller of capacity and energy for over 25 years in the wholesale power market. The customers of MPEX are other power suppliers in the Midwest and Canada. MPEX also contracts with its customers to provide hourly energy scheduling and power trading services. The Company's wholly owned subsidiary, Superior Water, Light and Power Company, sells electricity to 14,000 customers and natural gas to 11,000 customers, and provides water to 10,000 customers in northwestern Wisconsin. BNI Coal, Ltd. (BNI Coal), another wholly owned subsidiary of the Company, owns and operates a lignite mine in North Dakota. Two electric generating cooperatives, Minnkota Power Cooperative, Inc. and Square Butte Electric Cooperative (Square Butte), presently consume virtually all of BNI Coal's production of lignite coal under coal supply agreements extending to 2027. Under an agreement with Square Butte, Minnesota Power currently purchases about 71 percent of the output from the Square Butte unit which is capable of generating up to 455 megawatts (MW). Upon a two-year advance notice to Square Butte and the Company, beginning in 2006 Minnkota Power Cooperative, Inc., operator of the Square Butte generating unit, has the option to reduce the Company's entitlement by approximately 5 percent annually, to a minimum of 50 percent. In 1997 industrial customers contributed about half of the Company's electric operating revenue. The Company has large power contracts to sell power to eleven industrial customers (five taconite producers, four paper and pulp mills, and two pipeline companies) each requiring 10 MW or more of power. These contracts, which have termination dates ranging from April 2001 to October 2008, require the Company to have a certain amount of generating capacity available. In turn each customer is required to pay a minimum monthly demand charge that covers the fixed costs associated with having capacity available to serve the customer, including a return on common equity. Under the contracts, industrial customers pay demand charges for the base portion of their capacity needs on a take-or-pay basis for the entire term of the contract, while most customers are permitted bi-annually (coincident with each power pool season) to establish their capacity needs above this base, thereby committing to additional demand charges. In addition to the demand charge, each customer is billed an energy charge for each kilowatthour used that recovers the variable costs incurred in generating electricity. WATER SERVICES Water Services include regulated and non-regulated wholly owned subsidiaries of the Company. Florida Water Services Corporation, which is the largest investor owned water supplier in Florida, provides water to 119,000 customers and wastewater treatment services to 53,000 customers in Florida. Heater Utilities, Inc. provides water to 29,000 customers and wastewater treatment services to 2,000 customers in North Carolina. Instrumentation Services, Inc. (ISI) provides predictive maintenance and instrumentation consulting services to water and wastewater utility companies, and other industrial operations throughout the southeastern part of the United States as well as Texas and Minnesota. U.S. Maintenance and Management Services Corporation (USM&M) was incorporated in 1997 to complement ISI's operations. USM&M provides maintenance services to water and wastewater utilities, and other industrial operations primarily in Florida. Americas' Water Services Corporation, which is headquartered near Chicago, Illinois, offers contract management, operations and maintenance services to governments and industries in the Americas. -4- AUTOMOTIVE SERVICES Automotive Services include wholly owned subsidiaries operating as integral parts of the vehicle auction business: ADESA Corporation (ADESA), a network of vehicle auctions; Automotive Finance Corporation (AFC), a finance company; and Great Rigs Incorporated (Great Rigs), an auto transport company. ADESA is the third largest vehicle auction network in the United States. Headquartered in Indianapolis, Indiana, ADESA owns and operates 28 vehicle auction facilities in the United States and Canada through which used cars and other vehicles are purchased and sold to franchised automobile dealers and licensed used car dealers. Sellers at ADESA's auctions include domestic and foreign auto manufacturers, car dealers, fleet/lease companies, banks and finance companies. AFC provides inventory financing for wholesale and retail automobile dealers who purchase vehicles from ADESA auctions, independent auctions and other auction chains. AFC is headquartered in Indianapolis, Indiana, and has 63 loan production offices located at most ADESA auctions, as well as at or near independently owned auto auctions. From these offices car dealers obtain credit to purchase vehicles at any of the over 300 auctions approved by AFC. Great Rigs is one of the nation's largest independent used automobile transport carriers with 153 leased automotive carriers. Headquartered in Moody, Alabama, Great Rigs offers customers pick up and delivery service through 12 strategically located transportation hubs. Customers of Great Rigs include ADESA auctions, car dealerships, vehicle manufacturers, leasing companies, finance companies and other auctions. INVESTMENTS Minnesota Power's securities portfolio is managed by selected outside and inside managers and is intended to provide stable earnings and liquidity. The Company's objective is to maintain corporate liquidity between 7 percent and 10 percent of total assets ($150 million to $200 million). The Company plans to continue to concentrate in market-neutral investment strategies designed to provide stable and acceptable returns without sacrificing needed liquidity. The securities portfolio is structured to perform so as to provide an after-tax return of between 7 percent and 9 percent. While these returns may seem modest compared to broader market indices over the past three years, the Company believes its investment strategy is a wise course in a volatile economic environment. Returns will continue to be partially dependent on general market conditions. The Company's investment in the securities portfolio at March 31, 1998 was approximately $190 million. Minnesota Power owns 6.5 million shares of Capital Re Corporation (Capital Re), a specialty insurance and reinsurance business. Capital Re's product lines currently include financial guaranty, mortgage, title, financial, credit and specialty reinsurance, and specialty insurance through its participation in Lloyds of London. Capital Re trades on the New York Stock Exchange under the symbol KRE. Minnesota Power's ownership represents 21 percent of the 32 million total outstanding shares of Capital Re. The market value of the Company's investment in Capital Re was $210 million at March 31, 1998 based on a Capital Re share price of $32.125. The Company accounts for its investment in Capital Re under the equity method and the carrying value was $123 million at March 31, 1998. The Company owns 80 percent of Lehigh Acquisition Corporation (Lehigh), a real estate company in Florida. Lehigh owns 2,500 acres of land and approximately 4,000 home sites near Fort Myers, Florida; 1,000 home sites in Citrus County, Florida; and 2,700 home sites and 12,000 acres of residential, commercial and industrial land at Palm Coast, Florida. -5- SELLING SHAREHOLDERS The following table lists the Selling Shareholders, the number of shares of Common Stock of the Company beneficially owned by the Selling Shareholders as of the date of this Prospectus, the number of shares to be offered and the number of outstanding shares to be owned after the sale. Minnesota Power contributed the shares to MP Water Resources Group, Inc. (MP Water Resources), a wholly owned subsidiary of Minnesota Power, which exchanged the Shares for 100 percent of the outstanding shares of common stock of Vibration Correction Services, Inc. owned by the Selling Shareholders. The Shares were issued by the Company and delivered by MP Water Resources to the Selling Shareholders in a private placement transaction that has been accounted for as a pooling of interest.

(2) As of July 10, 1998 the Selling Shareholders held less than one percent of the Company's then outstanding Common Stock. (3) As of June 17, 1998 the Selling Shareholders represented to the Company that they (i) were acquiring the Shares for their own account for investment and not with a view toward resale or distribution and (ii) did not at that time have any reason to anticipate any change in their circumstances or other particular occasion or event which would cause them to desire to sell or otherwise transfer the Shares.

The Company has paid dividends without interruption on its Common Stock since 1948, the date of the initial distribution of the Common Stock by American Power & Light Company, the former holder of all such stock. -6- The Company has a Dividend Reinvestment and Stock Purchase Plan (Plan). The Plan provides investors (Participants) with a convenient method of acquiring shares of Common Stock through (i) the reinvestment in Common Stock of all or a portion of the cash dividends payable on the Participant's holdings of Common Stock and Preferred Stocks, and/or (ii) the investment of optional cash payments pursuant to the terms of the Plan. The Company reserves the right to suspend, modify, amend or terminate the Plan at any time and to interpret and regulate the Plan as it deems necessary or desirable in connection with the operation of the Plan. Shares of Common Stock are offered for sale under the Plan only by means of a separate prospectus available upon request from the Company. DESCRIPTION OF COMMON STOCK General. The following statements relating to the Common Stock are merely an outline and do not purport to be complete. They are qualified in their entirety by reference to the Company's Articles of Incorporation (Articles of Incorporation) and the Mortgage and Deed of Trust of the Company. Reference is also made to the laws of the State of Minnesota. The Company's authorized capital stock consists of 130,000,000 shares of Common Stock, without par value, 116,000 shares of 5% Preferred Stock, $100 par value, 1,000,000 shares of Serial Preferred Stock, without par value, and 2,500,000 shares of Serial Preferred Stock A, without par value. Dividend Rights. The Common Stock is entitled to all dividends after full provision for dividends on the issued and outstanding Preferred Stocks and the sinking fund requirements of the Serial Preferred Stock A, $7.125 Series and $6.70 Series. The Articles of Incorporation provide that so long as any shares of the Company's Preferred Stocks are outstanding, cash dividends on Common Stock are restricted to 75 percent of available net income when Common Stock equity is or would become less than 25 percent but more than 20 percent of total capitalization. This restriction becomes 50 percent when such equity is or would become less than 20 percent. See Note 10 to Consolidated Financial Statements incorporated by reference in the Company's 1997 Form 10-K. Voting Rights (Non-Cumulative Voting). Holders of Common Stock are entitled to notice of and to vote at any meeting of shareholders. Each share of the Common Stock, as well as each share of the issued and outstanding Preferred Stocks, is entitled to one vote. Since the holders of such shares do not have cumulative voting rights, the holders of more than 50 percent of the shares voting can elect all the Company's directors, and in such event the holders of the remaining shares voting (less than 50 percent) cannot elect any directors. In addition, the Preferred Stocks are expressly entitled, as one class, to elect a majority of the directors (the Common Stock, as one class, electing the minority) whenever dividends on any of such Preferred Stocks shall be in default in the amount of four quarterly payments and thereafter until all such dividends in default shall have been paid. The Articles of Incorporation include detailed procedures and other provisions relating to these rights and their termination, such as quorums, terms of directors elected, vacancies, class voting as between Preferred Stocks and Common Stock, meetings, adjournments and other matters. The Articles of Incorporation contain certain provisions which make it difficult to obtain control of the Company through transactions not having the approval of the Board of Directors, including: (1) A provision requiring the affirmative vote of 75 percent of the outstanding shares of all classes of capital stock of the Company, present and entitled to vote, in order to authorize certain "Business Combinations." Any such Business Combination is required to meet certain "fair price" and procedural requirements. Neither a 75 percent stockholder vote nor "fair price" is required for any Business Combination which has been approved by a majority of the "Disinterested Directors." (2) A provision permitting a majority of the Disinterested Directors to determine whether the above requirements have been satisfied. (3) A provision providing that certain of the Articles of Incorporation cannot be altered unless approved by 75 percent of the outstanding shares of all classes of capital stock, present and -7- entitled to vote, unless such alteration is recommended to the shareholders by a majority of the Disinterested Directors. Liquidation Rights. After satisfaction of creditors and of the preferential liquidation rights of the outstanding Preferred Stocks ($100 per share plus unpaid accumulated dividends), the holders of the Common Stock are entitled to share ratably in the distribution of all remaining assets. Miscellaneous. Holders of Common Stock have no preemptive or conversion rights. The Common Stock is listed on the New York Stock Exchange. The transfer agents and registrars for the Common Stock are Norwest Bank Minnesota, N.A. and the Company. DESCRIPTION OF PREFERRED SHARE PURCHASE RIGHTS Reference is made to the Rights Agreement, dated as of July 24, 1996 (Rights Plan) between the Company and the Corporate Secretary of the Company, as Rights Agent. The description of the Rights set forth below does not purport to be complete and is qualified in its entirety by reference to the Rights Plan. Reference is also made to the laws of the State of Minnesota. On July 24, 1996, the Board of Directors of the Company declared a dividend distribution of one Right for each outstanding share of Common Stock to shareholders of record at the close of business on July 24, 1996 (Record Date) and authorized the issuance of one Right with respect to each share of Common Stock that becomes outstanding between the Record Date and July 23, 2006 or such earlier time as the Rights are redeemed. Except as described below, each Right, when exercisable, entitles the registered holder to purchase from the Company one one-hundredth of a share of Junior Serial Preferred Stock A, without par value (Serial Preferred), at a price of $90 per one one-hundredth share (the Purchase Price), subject to adjustment. No separate Right Certificates will be distributed. The Rights will be evidenced by the Common Stock certificates together with a copy of the Summary of Rights Plan and not by separate certificates until the earlier to occur of (i) 10 days following a public announcement that a person or group of affiliated or associated persons (an Acquiring Person) has acquired, or obtained the right to acquire, beneficial ownership of 15 percent or more of the outstanding shares of Common Stock (the Stock Acquisition Date) or (ii) 15 business days (or such later date as may be determined by action of the Board of Directors prior to the time that any person becomes an Acquiring Person) following the commencement of (or a public announcement of an intention to make) a tender or exchange offer if, upon consummation thereof, such person or group would be the beneficial owner of 15 percent or more of such outstanding shares of Common Stock (the earlier of such dates being called the Distribution Date). Until the Distribution Date, the Rights will be transferred with and only with the Common Stock. Until the Distribution Date (or earlier redemption, expiration or termination of the Rights), the transfer of any certificates for Common Stock, with or without a copy of the Summary of Rights Plan, will also constitute the transfer of the Rights associated with the Common Stock represented by such certificates. As soon as practicable following the Distribution Date, separate certificates evidencing the Rights (Right Certificates) will be mailed to holders of record of the Common Stock as of the close of business on the Distribution Date and, thereafter, such separate Right Certificates alone will evidence the Rights. Each whole share of Serial Preferred will have a minimum preferential quarterly dividend rate equal to the greater of $51 per share or, subject to anti-dilution adjustment, 100 times the dividend declared on the Common Stock. In the event of liquidation, no distribution will be made to the holders of Common Stock unless, prior thereto, the holders of the Serial Preferred have received a liquidation preference of $100 per share, plus accrued and unpaid dividends. Holders of the Serial Preferred will be entitled to notice of and to vote at any meeting of the Company's shareholders. Each whole share of Serial Preferred is entitled to one vote. Such shares do not have cumulative voting rights. The Serial Preferred, together with the issued and outstanding shares of the other Preferred Stocks of the Company, will be expressly entitled, as one class, to elect a majority of directors (the Common Stock electing the minority) whenever dividends on any -8- of the Preferred Stocks shall be in default in the amount of four quarterly payments and thereafter until all such dividends in default shall have been paid. In the event of any merger, consolidation or other transaction in which shares of Common Stock are exchanged for or converted into other securities and/or property, each whole share of Serial Preferred will be entitled to receive, subject to anti-dilution adjustment, 100 times the amount into which or for which each share of Common Stock is so exchanged or converted. The shares of Serial Preferred are not redeemable by the Company. The Rights are not exercisable until the Distribution Date and will expire at the earliest of (i) July 23, 2006 (Final Expiration Date), (ii) the redemption of the Rights by the Company as described below, and (iii) the exchange of all Rights for Common Stock as described below. In the event that any person (other than the Company, its affiliates or any person receiving newly-issued shares of Common Stock directly from the Company) becomes the beneficial owner of 15 percent or more of the then outstanding shares of Common Stock, each holder of a Right will thereafter have a right to receive, upon exercise at the then current exercise price of the Right, Common Stock (or, in certain circumstances, cash, property or other securities of the Company) having a value equal to two times the exercise price of the Right. The Rights Plan contains an exemption for any issuance of Common Stock by the Company directly to any person (for example, in a private placement or an acquisition by the Company in which Common Stock is used as consideration), even if that person would become the beneficial owner of 15 percent or more of the Common Stock, provided that such person does not acquire any additional shares of Common Stock. In the event that, at any time following the Stock Acquisition Date, the Company is acquired in a merger or other business combination transaction or 50 percent or more of the Company's assets or earning power are sold, proper provision will be made so that each holder of a Right will thereafter have the right to receive, upon exercise at the then current exercise price of the Right, common stock of the acquiring or surviving company having a value equal to two times the exercise price of the Right. Notwithstanding the foregoing, following the occurrence of any of the events set forth in the preceding two paragraphs (the Triggering Events), any Rights that are, or (under certain circumstances specified in the Rights Plan) were, beneficially owned by any Acquiring Person will immediately become null and void. The Purchase Price payable, and the number of shares of Serial Preferred or other securities or property issuable, upon exercise of the Rights, are subject to adjustment from time to time to prevent dilution, among other circumstances, in the event of a stock dividend on, or a subdivision, split, combination, consolidation or reclassification of, the Serial Preferred or the Common Stock, or a reverse split of the outstanding shares of Serial Preferred or the Common Stock. At any time after the acquisition by a person or group of affiliated or associated persons of beneficial ownership of 15 percent or more of the outstanding Common Stock and prior to the acquisition by such person or group of 50 percent or more of the outstanding Common Stock, the Board of Directors may exchange the Rights (other than Rights owned by such person or group, which have become void), in whole or in part, at an exchange ratio of one share of Common Stock per Right (subject to adjustment). With certain exceptions, no adjustment in the Purchase Price will be required until cumulative adjustments require an adjustment of at least one percent in the Purchase Price. The Company will not be required to issue fractional shares of Serial Preferred or Common Stock (other than fractions in multiples of one one-hundredths of a share of Serial Preferred) and, in lieu thereof, an adjustment in cash may be made based on the market price of the Serial Preferred or Common Stock on the last trading date prior to the date of exercise. At any time after the date of the Rights Plan until the time that a person becomes an Acquiring Person, the Board of Directors may redeem the Rights in whole, but not in part, at a price of $.01 per Right (Redemption Price), which may (at the option of the Company) be paid in cash, shares of Common Stock or other consideration deemed appropriate by the Board of Directors. Upon the effectiveness of any action of the Board of Directors ordering redemption of the Rights, the Rights will terminate and the only right of the holders of Rights will be to receive the Redemption Price. -9- Issuance of Serial Preferred or Common Stock upon exercise of the Rights will be subject to any necessary regulatory approvals. Until a Right is exercised, the holder thereof, as such, will have no rights as a shareholder of the Company, including, without limitation, the right to vote or to receive dividends. One million shares of Serial Preferred were reserved for issuance in the event of exercise of the Rights. The provisions of the Rights Plan may be amended by the Company, except that any amendment adopted after the time that a person becomes an Acquiring Person may not adversely affect the interests of holders of Rights. The Rights have certain anti-takeover effects. The Rights will cause substantial dilution to a person or group that attempts to acquire the Company without conditioning the offer on the Rights being redeemed or a substantial number of Rights being acquired, and under certain circumstances the Rights beneficially owned by such a person or group may become void. The Rights should not interfere with any merger or other business combination approved by the Board of Directors because, if the Rights would become exercisable as a result of such merger of business combination, the Board of Directors may, at its option, at any time prior to the time that any person becomes an Acquiring Person, redeem all (but not less than all) of the then outstanding Rights at the Redemption Price.

INDEMNIFICATION OF DIRECTORS AND OFFICERS. Section 302A.521 of the Minnesota Business Corporation Act generally provides for the indemnification of directors, officers or employees of a corporation made or threatened to be made a party to a proceeding by reason of the former or present official capacity of the person against judgments, penalties and fines (including attorneys' fees and disbursements) where such person, among other things, has not been indemnified by another organization, acted in good faith, received no improper personal benefit and with respect to any criminal proceeding, had no reasonable cause to believe his conduct was unlawful. Section 13 of the Bylaws of the Company contains the following provisions relative to indemnification of directors and officers: "The Company shall reimburse or indemnify each present and future director and officer of the Company (and his or her heirs, executors and administrators) for or against all expenses reasonably incurred by such director or officer in connection with or arising out of any action, suit or proceeding in which such director or officer may be involved by reason of being or having been a director or officer of the Company. Such indemnification for reasonable expenses is to be to the fullest extent permitted by the Minnesota Business Corporation Act, Minnesota Statutes Chapter 302A. By affirmative vote of the Board of Directors or with written approval of the Chairman and Chief Executive Officer, such indemnification may be extended to include agents and employees who are not directors or officers of the Company, but who would otherwise be indemnified for acts and omissions under Chapter 302A of the Minnesota Business Corporation Act, if such agent or employee were an officer of the Company." "Reasonable expenses may include reimbursement of attorney's fees and disbursements, including those incurred by a person in connection with an appearance as a witness." "Upon written request to the Company and approval by the Chairman and Chief Executive Officer, an agent or employee for whom indemnification has been extended, or an officer or director may receive an advance for reasonable expenses if such agent, employee, officer or director is made or threatened to be made a party to a proceeding involving a matter for which indemnification is believed to be available under Minnesota Statutes Chapter 302A." "The foregoing rights shall not be exclusive of other rights to which any director or officer may otherwise be entitled and shall be available whether or not the director or officer continues to be a director or officer at the time of incurring such expenses and liabilities." The Company has insurance covering its expenditures which might arise in connection with the lawful indemnification of its directors and officers for their liabilities and expenses, and insuring officers and directors of the Company against certain other liabilities and expenses.

The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement. Provided, however, that paragraphs (i) and (ii) do not apply if the registration statement is on Form S-3 or Form S-8 and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (4) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (5) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. II-5 POWER OF ATTORNEY Each person whose signature appears below hereby authorizes any agent for service named in this registration statement to execute in the name of each such person, and to file with the Securities and Exchange Commission, any and all amendments, including post-effective amendments, to the registration statement, and appoints any such agent for service as attorney-in-fact to sign in each such person's behalf individually and in each capacity stated below and file any such amendments to the registration statement and the registrant hereby also appoints each such agent for service as its attorney-in-fact with like authority to sign and file any such amendments in its name and behalf.
