SAFE HARBOR STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995 In connection with the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, ALLETE is hereby filing cautionary statements identifying important factors that could cause ALLETE's actual results to differ materially from those projected in forward-looking statements (as that term is defined in the Private Securities Litigation Reform Act of 1995) made by or on behalf of ALLETE which are made in this prospectus or any supplement to this prospectus, in presentations, in response to questions or otherwise. Any statements that express, or involve discussions as to, expectations, beliefs, plans, objectives, assumptions or future events or performance (often, but not always, through the use of words or phrases such as "anticipates," "believes," "estimates," "expects," "intends," "plans," "projects," "will likely," "result," "will continue" or similar expressions) are not statements of historical facts and may be forward-looking. Forward-looking statements involve estimates, assumptions 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 3

uncertainties, are beyond the control of ALLETE and may cause actual results to differ materially from those contained in those forward-looking statements: o prevailing governmental policies and regulatory actions, including those of the United States Congress, state legislatures, the Federal Energy Regulatory Commission, the Minnesota Public Utilities Commission, the Florida Public Service Commission, the North Carolina Utilities Commission and the Public Service Commission of Wisconsin and various county regulators, 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 present or prospective wholesale and retail competition (including but not limited to retail wheeling and transmission costs); o economic and geographic factors, including political and economic risks; o changes in and compliance with environmental and safety laws and policies; o weather conditions; o population growth rates and demographic patterns; o competition for retail and wholesale customers; o pricing and transportation of commodities; o market demand, including structural market changes; o changes in tax rates or policies or in rates of inflation; o changes in project costs; o unanticipated changes in operating expenses and capital expenditures; o capital market conditions; o competition for new energy development opportunities; and o legal and administrative proceedings (whether civil or criminal) and settlements that influence the business and profitability of ALLETE. Any forward-looking statement speaks only as of the date on which that statement is made, and ALLETE undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date on which that statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time and it is not possible for management to predict all of those factors, nor can it assess the impact of each of those factors on the businesses of ALLETE or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statement. 4

DESCRIPTION OF COMMON STOCK General. The following statements describing our common stock are not intended to be a complete description. They are qualified in their entirety by reference to our Articles of Incorporation and Mortgage and Deed of Trust. We also refer you to the laws of the State of Minnesota. We have the following authorized capital stock by our Articles of Incorporation: 130,000,000 shares of common stock, without par value, and 3,616,000 shares of preferred stock. As of the date of this prospectus, 75,335,983 shares of common stock were issued and outstanding and no shares of preferred stock were issued and outstanding. Dividend Rights. Our common stock is entitled to dividends only after we have provided for dividends and any sinking fund requirements on any issued and outstanding preferred stock. Our Articles of Incorporation contain provisions which would restrict net income available for the payment of cash dividends on outstanding common stock in the event that shares of ALLETE's preferred stock were outstanding and certain common stock equity capitalization ratios were not met. Voting Rights (Non-Cumulative Voting). Holders of our common stock are entitled to receive notice of and to vote at any meeting of our shareholders. Each share of our common stock, as well as each share of any of our issued and outstanding preferred stock, is entitled to one vote. Since the holders of these shares do not have cumulative voting rights, the holders of more than 50 percent of the shares voting can elect all our directors. If that happens, the holders of the remaining shares voting (less than 50 percent) cannot elect any directors. In addition, whenever dividends on any of our preferred stock are in default in the amount of four quarterly payments, and until all the dividends in default are paid, the holders of our preferred stock are entitled, as one class, to elect a majority of the directors. Our common stock, as one class, would then elect the minority. Our Articles of Incorporation include detailed procedures and other provisions relating to these rights and their termination, including: o Quorums; o Terms of directors elected; o Vacancies; o Class voting; o Meetings; and 8

o Adjournments. Our Articles of Incorporation contain provisions that make it difficult to obtain control of ALLETE through transactions not having the approval of our Board of Directors. These provisions include: o a provision requiring the affirmative vote of 75 percent of the outstanding shares of all classes of our capital stock, present and entitled to vote, in order to authorize certain mergers or consolidations, or sales or leases of a significant amount of assets, of ALLETE, and other significant transactions that may have an effect on the control of ALLETE. Any of those transactions are required to meet certain "fair price" and procedural requirements. Neither a 75 percent shareholder vote nor "fair price" is required for any of those transactions that have been approved by a majority of the "Disinterested Directors," as that term is defined in our Articles of Incorporation; o a provision permitting a majority of the Disinterested Directors to determine whether the above requirements have been satisfied; and o a provision providing that some parts of our Articles of Incorporation cannot be altered unless approved by 75 percent of the outstanding shares of all classes of our capital stock, present and entitled to vote, unless the alteration is recommended to the shareholders by a majority of the Disinterested Directors. The parts of our Articles of Incorporation that cannot be altered except as stated above include some parts relating to: - mergers or consolidations, or sales or leases of a significant amount of assets, of ALLETE, and other significant transactions that may have an effect on the control of ALLETE; and - the number, election, terms of office and removal of directors of ALLETE and the way in which vacancies on the Board of Directors are filled. Liquidation Rights. After we have satisfied creditors and the preferential liquidation rights of any of our outstanding preferred stock, the holders of our common stock are entitled to share ratably in the distribution of all remaining assets. Miscellaneous. Holders of our common stock have no preemptive or conversion rights. Our common stock is listed on the New York Stock Exchange. The transfer agents and registrars for our common stock are Wells Fargo Bank, N.A. and ALLETE. Description of Preferred Share Purchase Rights. The following statements describing our Preferred Share Purchase Rights (each a "Right") are not intended to be a complete description. They are qualified in their entirety by reference to the Rights Agreement, dated as of July 24, 1996 ("Rights Plan"), between ALLETE and ALLETE's Corporate Secretary, as Rights Agent. We also refer you to the laws of the State of Minnesota. In July 1996 our Board of Directors declared a dividend distribution of one Right for each outstanding share of our common stock to shareholders of record at the close of business on July 24, 1996 ("Record Date"). Our Board of Directors also authorized the issuance of one Right for each share of our common stock that becomes outstanding between the Record Date and July 23, 2006, or an earlier date on which the Rights are redeemed. Except as described below, each Right, when exercisable, entitles the registered holder to purchase from us one two-hundredth of a share of Junior Serial Preferred Stock A, without par value ("Serial Preferred"), at a price of $45 per one two-hundredth of a share (the "Purchase Price"). The Purchase Price is subject to adjustment. Initially no separate Right Certificates will be distributed. Until the Distribution Date, our common stock certificates together with a copy of the Summary of Rights Plan are proof of the Rights. The Distribution Date is the earlier to occur of: o 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 our common stock (the "Stock Acquisition Date"); or 9

o 15 business days following the commencement of (or a public announcement of an intention to make) a tender or exchange offer where a person or group would become the beneficial owner of 15 percent or more of our outstanding shares of common stock. At any time before a person becomes an Acquiring Person, our Board of Directors may extend the 15-business day time period. Until the Distribution Date (or the earlier redemption, expiration or termination of the Rights), the Rights will be transferred only with our common stock. The transfer of any certificates for our common stock, with or without a copy of the Summary of Rights Plan, will also constitute the transfer of the Rights associated with those common stock certificates. As soon as practicable following the Distribution Date, we will mail separate certificates for the Rights to holders of record of our common stock as of the close of business on the Distribution Date. After the Distribution Date, separate certificates for the Rights will be given as proof of the Rights. Each whole share of our Serial Preferred will have a minimum preferential quarterly dividend rate equal to the greater of $51 per share or, subject to anti-dilution adjustment, 200 times the dividend declared on our common stock. If ALLETE liquidates, no distribution will be made to the holders of our common stock until the holders of our Serial Preferred have received a liquidation preference of $100 per share, plus accrued and unpaid dividends. Holders of our Serial Preferred will be entitled to receive notice of and to vote at any meeting of our shareholders. Each whole share of our Serial Preferred is entitled to one vote. These shares do not have cumulative voting rights. Whenever dividends on any of our preferred stock are in default in the amount of four quarterly payments, and until all the dividends in default are paid, the holders of our Serial Preferred and other preferred stock will be entitled, together as one class, to elect a majority of directors. Our common stock would then elect the minority. If, in any merger or other transaction, shares of our common stock are exchanged for or converted into other securities and/or property, each whole share of our Serial Preferred will be entitled to receive, subject to anti-dilution adjustment, 200 times the amount for or into which each share of our common stock is exchanged or converted. We cannot redeem the shares of Serial Preferred. The Rights are not exercisable until the Distribution Date and will expire at the earliest of: o July 23, 2006 ("Final Expiration Date"); o the redemption of the Rights by ALLETE as described below; or o the exchange of all Rights for our common stock as described below. If any person (other than ALLETE, our affiliates or any person receiving newly-issued shares of common stock directly from ALLETE) becomes the beneficial owner of 15 percent or more of the then outstanding shares of common stock, each holder of a Right will have a right to receive, upon exercise at the then current exercise price of the Right, common stock (or, in the discretion of the Board of Directors, cash, property or other securities of ALLETE) with a value equal to two times the exercise price of the Right. The Rights Plan contains an exemption for common stock we issue directly to any person. This exemption applies even if the person would become the beneficial owner of 15 percent or more of our common stock, provided that the person does not acquire any additional shares of our common stock. Examples of situations where we might issue common stock directly include private placements or acquisitions we make using our common stock as consideration. If following the Stock Acquisition Date we are acquired in a merger or other business combination transaction, or 50 percent or more of our assets or earning power are sold, we will make proper provision so that each holder of a Right will, after the transaction, have the right to receive, upon exercise at the then current exercise price of the Right, common stock of the acquiring or surviving company with a value equal to two times the exercise price of the Right. If the events described in the preceding two paragraphs happen (the "Triggering Events"), any Rights that an Acquiring Person beneficially owns or transferred to certain persons, will immediately become null and void. 10

The Purchase Price payable and the number of shares of our Serial Preferred or other securities or property issuable if the Rights are exercised, are subject to adjustment. An adjustment would be made to prevent dilution, if there was a stock dividend on, or a subdivision, split, combination, consolidation or reclassification of, our Serial Preferred or our common stock, or a reverse split of our outstanding shares of Serial Preferred or common stock. Our Board of Directors may exchange the Rights at an exchange ratio of one share of common stock per Right at any time that is: o 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 o before the acquisition by that person or group of 50 percent or more of the outstanding common stock. This exchange ratio is subject to adjustment and does not include Rights that have become null and void. 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. We 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). Instead, we may make an adjustment in cash based on the market price of the Serial Preferred or common stock on the last trading date before the date of exercise. Our Board of Directors may redeem the Rights in whole, but not in part, at a price of $.005 per Right ("Redemption Price") anytime before a person becomes an Acquiring Person. At our option, we may pay the Redemption Price in cash, shares of our common stock or other consideration that our Board of Directors deems appropriate. If we redeem the Rights, the Rights will terminate and the only right of the holders of Rights will be to receive the Redemption Price. If the Rights are exercised, issuance of our Serial Preferred or our common stock will be subject to any necessary regulatory approvals. Until a Right is exercised, the holder of the Right will have no rights as a shareholder of ALLETE, including, without limitation, the right to vote or to receive dividends. One million shares of our Serial Preferred were reserved for issuance if the Rights are exercised. We may amend the provisions of the Rights Plan. However, 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 anti-takeover effects. The Rights will cause substantial dilution to a person or group that attempts to acquire ALLETE without conditioning the offer on the redemption of the Rights or on the acquisition of a substantial number of Rights. The Rights beneficially owned by that person or group may become null and void. The Rights should not interfere with any merger or other business combination approved by our Board of Directors. This is because, at any time before a person becomes an Acquiring Person, our Board of Directors may redeem all of the outstanding Rights at the Redemption Price. USE OF PROCEEDS ALLETE will not receive any of the proceeds from sales of these shares of common stock. PLAN OF DISTRIBUTION The selling shareholders may sell or distribute some or all of these shares of common stock from time to time through underwriters or dealers or brokers or other agents or directly through one or more purchasers, including pledgees, in transactions (which may involve crosses and block transactions) on the New York Stock Exchange or in privately negotiated transactions (including sales pursuant to pledges) or in a combination of such transactions. Such transactions may be effected by the selling shareholders at market prices prevailing at the time of sale, at prices related to prevailing market prices, at negotiated prices, or at fixed prices, which may be changed. Brokers, dealers, agents or underwriters 11

participating in such transactions as agent may receive compensation in the form of discounts, concessions or commissions from the selling shareholders (and, if they act as agent for the purchaser of such shares, from such purchaser). Such discounts, concessions or commissions as to a particular broker, dealer, agent or underwriter might be in excess of those customary in the type of transaction involved. This prospectus also may be used, with ALLETE's consent, by donees of the selling shareholders, or by other persons acquiring shares and who wish to offer and sell such shares under circumstances requiring or making desirable its use. When required, this prospectus will be supplemented to set forth the number of shares offered for sale and, if such offering is to be made by or through underwriters, dealers, brokers or other agents, the names of such persons and the principal terms of the arrangements between such persons and the selling shareholders. The selling shareholders and any underwriters, brokers, dealers or agents acting in connection with the sale or distribution of these shares of common stock hereunder may be deemed to be "underwriters" within the meaning of Section 2(11) of the Securities Act of 1933, and any commissions received by them and any profit realized by them on the resale of shares as principals may be deemed underwriting compensation under the Securities Act of 1933. To the extent that the selling shareholders are deemed to be "underwriters," the selling shareholders will be subject to the prospectus delivery requirements of the Securities Act of 1933. In addition, any shares of common stock covered by this prospectus which qualify for sale pursuant to Rule 144 promulgated under the Securities Act of 1933 may be sold under Rule 144 rather than pursuant to this prospectus. Furthermore, the selling shareholders may transfer shares of common stock in other ways not involving market makers or established trading markets, including directly by gift, distribution, or other transfer. The selling shareholders may enter into hedging transactions with broker-dealers in connection with distributions of shares of our common stock or otherwise. In such transactions, broker-dealers may engage in short sales of the shares of our common stock in the course of hedging the positions they assume with selling shareholders. The selling shareholders also may sell shares short and redeliver shares of our common stock to close out such short positions. The selling shareholders may enter into option or other transactions with broker-dealers which require the delivery to the broker-dealer of shares of our common stock. The broker-dealer may then resell or otherwise transfer such shares pursuant to this prospectus. The selling shareholders may also loan or pledge the shares of our common stock to a broker-dealer. The broker-dealer may sell the common stock so loaned, or upon a default the broker-dealer may sell the pledged shares pursuant to this prospectus. Expenses in connection with the registration of these shares of common stock under the Securities Act of 1933, including legal and accounting fees of ALLETE, will be paid by ALLETE. The selling shareholders may agree to indemnify any broker-dealer or agent against certain liabilities related to the selling of the shares of our common stock, including liabilities arising under the Securities Act of 1933.

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. Article IX of the Articles of Incorporation of ALLETE contains the following provision: "No director of this Corporation shall be personally liable to this Corporation or its stockholders for monetary damages for breach of fiduciary duty by that director as a director; provided, however, that this Article IX shall not eliminate or limit the liability of a director: (a) for any breach of the director's duty of loyalty to this Corporation or its stockholders; (b) for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of the law; (c) under Minnesota Statutes Section 302A.559 or 80A.23; (d) for any transaction from which the director derived an improper personal benefit; or (e) for any act or omission occurring prior to the date when this Article IX becomes effective. If, after the stockholders approve this provision, the Minnesota Business Corporation Act, Minnesota Statutes Chapter 302A, is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of this Corporation shall be deemed eliminated or limited to the fullest extent permitted by the Minnesota Business Corporation Act, as so amended. No amendment to or repeal of this Article IX shall apply to or have any affect on the liability or alleged liability of any director of this Corporation for or with respect to any acts or omissions of such director occurring prior to that amendment or repeal." Section 13 of the Bylaws of ALLETE contains the following provisions relative to indemnification of directors and officers: "The Corporation shall reimburse or indemnify each present and future Director and officer of the Corporation (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 Corporation. 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 Corporation, 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 Corporation." II-1

"Reasonable expenses may include reimbursement of attorneys' fees and disbursements, including those incurred by a person in connection with an appearance as a witness." "Upon written request to the Corporation 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." ALLETE 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 ALLETE 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 SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and (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 (a)(1)(i) and (a)(1)(ii) do not apply if 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 SEC 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 herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. b. 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 provisions described under Item 15 above, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 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 II-5

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 Securities Act of 1933 and will be governed by the final adjudication of such issue.

The interest rate for each Interest Period will be equal to LIBOR on the Interest Determination Date for that Interest Period plus .85%; provided, however, that in certain circumstances described below, the interest rate will be determined in an alternative manner without reference to LIBOR. Promptly upon determination, the Calculation Agent will notify the Corporate Trustee of the interest rate for the new Interest Period. The interest rate determined by the Calculation Agent, absent willful default, bad faith or manifest error, will be binding and conclusive upon the beneficial owners and holders of the bonds of this series, the Company and the Corporate Trustee. "Interest Period" means the period commencing on an interest payment date and ending on the day preceding the next succeeding interest payment date provided that the initial Interest Period will commence on the date of initial issuance. The "Interest Determination Date" for an Interest Period is the second London Business Day immediately preceding the first day of that Interest Period. For purposes of this calculation, "London Business Day" means a day on which dealings in deposits in U.S. dollars are transacted, or with respect to any future date, are expected to be transacted, in the London interbank market. "LIBOR" for any Interest Determination Date will be the offered rate for deposits in U.S. dollars having an index maturity of three months for a period commencing on the second London Business Day immediately following the Interest Determination Date (the "Three Month Deposits") in amounts of not less than $1,000,000, as that rate appears on Telerate Page 3750, or a successor reporter of such rates selected by the Calculation Agent and acceptable to the Company, at approximately 11:00 a.m., London time, on the Interest Determination Date (the "Reported Rate"). "Telerate Page 3750" means the display designated on page "3750" on Dow Jones Markets Limited (or such other page as may replace the 3750 page on that service or such other service or services as may be nominated by the British Bankers' Association for the purpose of displaying London interbank offered rates for U.S. dollar deposits). If the following circumstances exist on any Interest Determination Date, the Calculation Agent will determine the interest rate for the bonds of this series as follows: (1) In the event no Reported Rate appears on Telerate Page 3750 as of approximately 11:00 a.m., London time, on an Interest Determination Date, the Calculation Agent will request the principal London offices of each of four major banks in the London interbank market selected by the Calculation Agent (after consultation with the Company) to provide a quotation of the rate at which Three Month Deposits in amounts of not less than $1,000,000 are offered by it to prime banks in the London interbank market, as of approximately 11:00 a.m., London time, on that Interest Determination Date, that is representative of single transactions at that time (the "Representative Amounts"). If at least two rate quotations are provided, the interest rate will be the arithmetic mean of the rate quotations obtained by the Calculation Agent, plus .85%. In the event no Reported Rate appears on Telerate Page 3750 and the Calculation Agent obtains fewer than two rate quotations, the interest rate will be the arithmetic mean of the rates quoted at approximately 11:00 a.m., New York City time, on that Interest Determination Date, by three major banks in New York 9

City, selected by the Calculation Agent (after consultation with the Company), for loans in Representative Amounts in U.S. dollars to leading European banks, having an index maturity of three months for a period commencing on the second London Business Day immediately following that Interest Determination Date, plus .85%; provided, however, that if fewer than three banks selected by the Calculation Agent are quoting those rates, the interest rate for the applicable Interest Period will be the same as the interest rate in effect for the immediately preceding interest period. Upon the request of the holder of any of the bonds, the Calculation Agent will provide to that holder the interest rate in effect on the date of the request and, if determined, the interest rate for the next Interest Period. The interest will be paid to the persons in whose names the bonds of this series are registered at the close of business (1) on the business day prior to each interest payment date if the bonds of this series remain in book-entry only form or (2) on the 15th calendar day before each interest payment date if the bonds of this series do not remain in book-entry only form. The bonds of this series shall not be redeemable prior to October 20, 2001. On or after October 20, 2001, the Company may redeem the bonds of this series, at its option, in whole or in part from time to time, on any interest payment date prior to their maturity (each a "Redemption Date"). The Company will give notice of its intent to redeem any of the bonds of this series 30 days prior to a Redemption Date. If the Company redeems all or any part of the bonds of this series, it will pay a redemption price equal to 100% of the principal amount of the bonds of this series being redeemed plus accrued and unpaid interest thereon, if any, to the Redemption Date. Reference is made to the Mortgage for a description of the property mortgaged and pledged, the nature and extent of the security, the rights of the holders of the bonds and of the Trustees in respect thereof, the duties and immunities of the Trustees and the terms and conditions upon which the bonds are and are to be secured and the circumstances under which additional bonds may be issued. With the consent of the Company and to the extent permitted by and as provided in the Mortgage, the rights and obligations of the Company and/or the rights of the holders of the bonds and/or coupons and/or the terms and provisions of the Mortgage may be modified or altered by affirmative vote of the holders of at least 66 2/3% principal amount of the bonds then outstanding under the Mortgage and, if the rights of the holders of one or more, but less than all, series of bonds then outstanding are to be affected, then also by affirmative vote of the holders of at least 66 2/3% in principal amount of the bonds then outstanding of each series of bonds so to be affected (excluding in any case bonds disqualified from voting by reason of the Company's interest therein as provided in the Mortgage); provided that, without the consent of the holder hereof, no such modification or alteration shall, among other things, impair or affect the right of the holder to receive payment of the principal of (and premium, if any) and interest on this bond, on or after the respective due dates expressed herein, or permit the creation of any lien equal or prior to the lien of the Mortgage or deprive the holder of the benefit of a lien on the mortgaged and pledged property. 10

The principal hereof may be declared or may become due prior to the maturity date hereinbefore named on the conditions, in the manner and at the time set forth in the Mortgage, upon the occurrence of a default as in the Mortgage provided. This bond is transferable as prescribed in the Mortgage by the registered owner hereof in person, or by his duly authorized attorney, at the office or agency of the Company in the Borough of Manhattan, The City of New York, upon surrender and cancellation of this bond, and thereupon, a new fully registered bond of the same series for a like principal amount will be issued to the transferee in exchange herefor as provided in the Mortgage. The Company and the Trustees may deem and treat the person in whose name this bond is registered as the absolute owner hereof for the purpose of receiving payment and for all other purposes and neither the Company nor the Trustees shall be affected by any notice to the contrary. In the manner prescribed in the Mortgage, bonds of this series, upon surrender thereof for cancellation at the office or agency of the Company in the Borough of Manhattan, The City of New York, are exchangeable for a like aggregate principal amount of bonds of the same series of other authorized denominations. As provided in the Mortgage, the Company shall not be required to make transfers or exchanges of bonds of any series for a period of ten (10) days next preceding any interest payment date for bonds of said series. No recourse shall be had for the payment of the principal of or interest on this bond against any incorporator or any past, present or future subscriber to the capital stock, stockholder, officer, or director of the Company or of any predecessor or successor corporation, as such, either directly or through the Company or any predecessor of successor corporation, under any rule of law, statute or constitution or by the enforcement of any assessment or otherwise, all such liability of incorporators, subscribers, stockholders, officers, and directors being released by the holder or owner hereof by the acceptance of this bond and being likewise waived and released by the terms of the Mortgage. This bond shall not become obligatory until The Bank of New York, the Corporate Trustee under the Mortgage, or its successor thereunder, shall have signed the form of authentication certificate endorsed hereon. 11

LEGEND [Unless and until this bond is exchanged in whole or in part for certificated bonds registered in the names of the various beneficial holders hereof as then certified to the Trustee by the Depository Trust Company or its successor (the "Depositary"), this bond may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. Unless this certificate is presented by an authorized representative of the Depositary to the Company or its agent for registration of transfer, exchange or payment, and any certificate to be issued is registered in the name of Cede & Co., or in such other name as is requested by an authorized representative of the Depositary and any amount payable thereunder is made payable to Cede & Co., or such other name, ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL since the registered owner hereof, Cede & Co., has an interest herein. This bond may be exchanged for certificated bonds registered in the names of the various beneficial owners hereof if (a) the Depositary is at any time unwilling or unable to continue as depositary and a successor depositary is not appointed by the Company within 90 days, or (b) the Company elects to issue certificated bonds to beneficial owners (as certified to the Company by the Depositary)]. [End of Bond Form] (II) The Company has initially designated The Depository Trust Company as the Depository (the "Depository") for the bonds of the Twenty-seventh series. For as long as the bonds of the Twenty-seventh series are registered in the name of the Depository or its nominee, all payments of interest, principal and other amounts in respect of such bonds may be made to the Depository or its nominee in accordance with the Depository's applicable procedures. Notwithstanding any provision hereof or in the Indenture, none of the Company, or the Trustees, nor any agent of any such person, shall have any responsibility with respect to the Depository's procedures or for any payments, transfers or other transactions, or any notices or other communications, among the Depository, any of its direct or indirect participants and any beneficial owners of such bonds. Each of the Company, the Trustees and any agent for any such person may treat the registered holder as the sole and exclusive owner of the bonds of the Twenty-seventh series for all purposes under the Indenture, including for making payments on such bonds and for providing notices and obtaining consents under the Indenture. (III) Upon the occurrence of a Change of Control, the Company will be required to offer to redeem the bonds of the Twenty-seventh series, in whole or in part, on the next business day after such Change of Control at a redemption price equal to 101% of the principal amount of the bonds of the Twenty-seventh Series being redeemed plus accrued and unpaid interest thereon, if any, to the 13

redemption date. The holders of the bonds of the Twenty-seventh Series will be permitted twenty business days after the offer in which to accept the offer by written notice to the Company. The Company will tender the redemption price to the accepting holders in exchange for their bonds of the Twenty-seventh Series within twenty business days after receipt of timely written notice of acceptance from those holders. A "Change of Control" shall be deemed to have occurred if at any time that any of the bonds of the Twenty-seventh Series are outstanding the following events shall occur: (1) Any "person" (as defined in Section 13(d) and 14(d)(2) of the Securities Exchange Act of 1934, as amended (the "Exchange Act")), excluding for this purpose the Company or any subsidiary of the Company or any Intermediate Holding Company, or any employee benefit plan of the Company or any subsidiary of the Company, or any person or entity organized, appointed or established by the Company for or pursuant to the terms of such plan which acquires beneficial ownership of voting securities of the Company, is or becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act) directly or indirectly of securities of the Company representing fifty percent (50%) or more of the combined voting power (not depending on the happening of a contingency) for the election of a majority of the members of the board of directors or any other governing body of the Company; provided, however, that no Change in Control shall be deemed to have occurred as the result of an acquisition of securities of the Company by the Company which, by reducing the number of voting securities outstanding, increases the direct or indirect beneficial ownership interest of any person to fifty percent (50%) or more of the combined voting power of the Company's then outstanding securities, but any subsequent increase in the direct or indirect beneficial ownership interest of such a person in the Company shall be deemed a Change in Control; and provided further that if the Board of Directors of the Company determines in good faith that a person who has become the beneficial owner directly or indirectly of securities of the Company representing fifty percent (50%) or more of the combined voting power of the Company's then outstanding securities has inadvertently reached that level of ownership interest, and if such person divests within 45 days after notice to the Company a sufficient amount of securities of the Company so that the person no longer has a direct or indirect beneficial ownership interest in fifty percent (50%) or more of the combined voting power of the Company's then outstanding securities, then no Change in Control shall be deemed to have occurred; or (2) Consummation of (a) an agreement for the sale or disposition of the Company or all or substantially all of the Company's assets, (b) a plan of merger or consolidation of the Company with any other company, or (c) a similar transaction or series of transactions involving the Company (any transaction described in parts (a) through (c) of this subparagraph being referred to as a "Business Combination"), in each case unless after such a Business Combination the shareholders of the Company immediately prior to the Business Combination continue to own, directly or indirectly, more than fifty (50%) of the combined voting power of the then outstanding voting securities entitled to vote generally in the election of directors of the new (or continued) entity. 14

"Intermediate Holding Company" means any entity organized or established by or with the consent of the Company which acquires, directly or indirectly, voting securities of the Company in exchange for voting securities of such entity. (IV) So long as the bonds of the Twenty-seventh Series remain outstanding, the Company will not merge its regulated electric utility business with its auto auction business in the same legal entity. (V) At the option of the registered owner, any bonds of the Twenty-seventh Series, upon surrender thereof for cancellation at the office or agency of the Company in the Borough of Manhattan, The City of New York, together with a written instrument of transfer wherever required by the Company duly executed by the registered owner or by his duly authorized attorney, shall (subject to the provisions of Section 12 of the Mortgage) be exchangeable for a like aggregate principal amount of bonds of the same series of other authorized denominations. Bonds of the Twenty-seventh Series shall be transferable (subject to the provisions of Section 12 of the Mortgage) at the office or agency of the Company in the Borough of Manhattan, The City of New York. Upon any exchange or transfer of bonds of the Twenty-seventh Series, the Company may make a charge therefor sufficient to reimburse it for any tax or taxes or other governmental charge, as provided in Section 12 of the Mortgage, but the Company hereby waives any right to make a charge in addition thereto for any exchange or transfer of bonds of the Twenty-seventh Series. Upon the delivery of this Twenty-first Supplemental Indenture and upon compliance with the applicable provisions of the Mortgage, there shall be an initial issue of bonds of the Twenty-seventh Series for the aggregate principal amount of $250,000,000. ARTICLE II DIVIDEND COVENANT SECTION 2. The Company covenants and agrees that the provisions of subdivision (III) of Section 39 of the Mortgage, which are to remain in effect so long as any of the bonds of the First Series shall remain Outstanding, shall remain in full force and effect so long as any bonds of the First through Twenty-seventh Series shall remain Outstanding. ARTICLE III AMENDMENT TO THE MORTGAGE - MEETINGS AND CONSENTS OF BONDHOLDERS SECTION 3. Pursuant to the reservation of right in Section 3 of the Fifth Supplemental Indenture dated as of April 1, 1971 and there being no Outstanding bonds of any series created prior to the Sixth Series, the Company hereby amends 15

the Mortgage, as supplemented, by substituting for Article XIX (relating to Meetings and Consents of Bondholders) a new Article XIX to read as set forth in Section 3 of such Fifth Supplemental Indenture. ARTICLE IV MISCELLANEOUS PROVISIONS SECTION 4. Subject to the amendments provided for in this Twenty-first Supplemental Indenture, the terms defined in the Mortgage, as heretofore supplemented, shall, for all purposes of this Twenty-first Supplemental Indenture, have the meanings specified in the Mortgage, as heretofore supplemented. SECTION 5. The holders of bonds of the Twenty-seventh Series consent that the Company may, but shall not be obligated to, fix a record date for the purpose of determining the holders of bonds of the Twenty-seventh Series entitled to consent to any amendment, supplement or waiver. If a record date is fixed, those persons who were holders at such record date (or their duly designated proxies), and only those persons, shall be entitled to consent to such amendment, supplement or waiver or to revoke any consent previously given, whether or not such persons continue to be holders after such record date. No such consent shall be valid or effective for more than 90 days after such record date. SECTION 6. The Trustees hereby accept the trusts herein declared, provided, created or supplemented and agree to perform the same upon the terms and conditions herein and in the Mortgage set forth and upon the following terms and conditions: The Trustees shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Twenty-first Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made by the Company solely. In general, each and every term and condition contained in Article XVII of the Mortgage shall apply to and form part of this Twenty-first Supplemental Indenture with the same force and effect as if the same were herein set forth in full with such omissions, variations and insertions, if any, as may be appropriate to make the same conform to the provisions of this Twenty-first Supplemental Indenture. SECTION 7. Whenever in this Twenty-first Supplemental Indenture any party hereto is named or referred to, this shall, subject to the provisions of Articles XVI and XVII of the Mortgage, as heretofore supplemented, be deemed to include the successors or assigns of such party, and all the covenants and agreements in this Twenty-first Supplemental Indenture contained by or on behalf of the Company, or by or on behalf of the Trustees shall, subject as aforesaid, bind and inure to the benefit of the respective successors and assigns of such party whether so expressed or not. SECTION 8. Nothing in this Twenty-first Supplemental Indenture, expressed or implied, is intended, or shall be construed, to confer upon, or give to, any person, firm or corporation, other than the parties hereto and the holders of the bonds and coupons Outstanding under the Mortgage, any right, remedy, or claim under or by reason of this Twenty-first Supplemental Indenture or any 16

covenant, condition, stipulation, promise or agreement hereof, and all the covenants, conditions, stipulations, promises and agreements in this Twenty-first Supplemental Indenture contained by and on behalf of the Company shall be for the sole and exclusive benefit of the parties hereto, and of the holders of the bonds and of the coupons Outstanding under the Mortgage. SECTION 9. This Twenty-first Supplemental Indenture shall be executed in several counterparts, each of which shall be an original and all of which shall constitute but one and the same instrument. SECTION 10. The Company, the mortgagor named herein, by its execution hereof acknowledges receipt of a full, true and complete copy of this Twenty-first Supplemental Indenture. 17
