Interest on the PHONES began accruing on February 1, 2000. We will pay this interest quarterly in arrears on February 15, May 15, August 15 and November 15 of each year, but subject to our right to defer quarterly payments of basic interest beginning after the February 15, 2003 payment. We will also distribute to you, based on the number of reference shares attributable to each PHONES, o an amount equal to any regular cash dividends paid during the preceding quarterly period on those reference shares; and o as additional interest, any property, including cash (other than any regular cash dividends), distributed on or in respect of those reference shares (other than publicly traded equity securities, which will themselves become reference shares). As of the date of this prospectus, McLeodUSA has never paid a cash dividend on its McLeodUSA stock. If the additional interest on the reference shares includes publicly traded securities (other than equity securities) that can be transferred by us to you without registration under the federal securities laws and without breach of our contractual arrangements with McLeodUSA, and that will be freely transferable in your hands, then we will distribute those securities to you. Otherwise, we will distribute to you the then fair market value of any property comprising additional interest as determined in good faith by our board of directors. We will distribute any additional interest, including publicly traded securities not meeting the standards set forth above, to you within 20 business days after it is distributed to us. The contingent principal amount for each PHONES as of May 15, 2001 was $67.75. The contingent principal amount for each PHONES will be increased during each quarter, based on the contingent principal amount at the beginning of the quarter, by an amount equal to interest accrued on that beginning contingent principal amount at the basic interest rate on the PHONES then in effect, and will be reduced by the following amounts on the dates they are paid to holders of the PHONES: o the quarterly basic interest payment made on the PHONES; 7 o any amounts paid on the PHONES in respect of regular cash dividends paid on the reference shares during the quarter; and o any amounts paid on the PHONES in respect of the fair market value of any additional interest payments made during the quarter. As a result, the quarterly computations of the contingent principal amount will be made such that the yield to each date of computation (including all quarterly basic interest, all amounts paid in respect of regular cash dividends on the reference shares, and the fair market value of any additional interest payments) does not exceed a 7.25% annual yield, if such date of computation is on or before February 15, 2003, or the weighted average of a 7.25% annual yield through February 15, 2003, and of a 2.50% annual yield thereafter, if such date of computation is after February 15, 2003. Notwithstanding the foregoing, in the event that we redeem the PHONES on a date which is between February 1 and February 15, 2003, the contingent principal amount will not be increased by an amount equal to the interest accrued on the beginning contingent principal amount for the quarterly interest payment period beginning on November 15, 2002. In no event will the contingent principal amount be less than zero. Changes in the contingent principal amount will not affect the amount to be paid to holders of the PHONES in respect of the quarterly payments of basic interest, amounts relating to regular cash dividends on the reference shares, or additional interest. When Can We Defer Payments of Basic Interest? We can defer quarterly basic interest payments on the PHONES as many times as we want beginning after the February 15, 2003 payment, but only for up to 20 consecutive quarterly periods. We cannot defer additional interest payments or quarterly payments equal to regular cash dividends paid on the reference shares at any time, and we cannot defer quarterly basic interest payments if an Event of Default (as defined on page 41) under the PHONES has occurred and is continuing. A deferral of basic interest payments cannot extend beyond the maturity date of the PHONES. If we defer quarterly payments of basic interest, the contingent principal amount of the PHONES will increase by the amount of the deferred quarterly payments of basic interest, plus accrued interest thereon at an annual rate of 2.50%, compounded quarterly, and the early exchange ratio (as defined on page 9) will be 100% of the reference shares for the quarter following each deferral of a payment of quarterly basic interest. Once we have paid all deferred quarterly basic interest, plus accrued interest thereon, together with the quarterly basic interest payment for the current quarterly interest payment period, the contingent principal amount will be reduced by the amount of that payment of deferred quarterly basic interest plus accrued interest thereon, the early exchange ratio will change to 95% of the reference shares, and we can again defer quarterly basic interest payments as described above. We have no current intention of deferring basic interest payments on the PHONES. When Will the PHONES Mature? The PHONES will mature on February 15, 2030, unless they have been previously redeemed or exchanged. If the contingent principal amount is reduced to zero or if all of the reference shares cease to be outstanding as a result of a tender offer, an exchange offer, a business combination or otherwise, the maturity of the PHONES will not be accelerated and the PHONES will continue to remain outstanding, you will 8 continue to receive quarterly payments of basic interest until the maturity date unless earlier redeemed by us, and you will receive the contingent principal amount, if any, on redemption or at maturity. What Will You Receive at Maturity? At maturity you will be entitled to receive the higher of (a) the contingent principal amount of the PHONES, or (b) the sum of the then current market value of the reference shares on the maturity date plus any deferred quarterly payments of basic interest (including any current accrued interest thereon), plus, in either case, the final period distribution. In addition, if the distribution date for any distribution of additional interest falls after the maturity date, we will make the distribution on the distribution date. Do We Have the Right to Redeem the PHONES Prior to Their Maturity? Yes. We may redeem at any time all but not some of the PHONES at a redemption price equal to the sum of (a) the higher of (1) the contingent principal amount of the PHONES or (2) the sum of the then current market value of the reference shares on the redemption date plus any deferred quarterly payments of basic interest (including any current accrued interest thereon), plus, in the case of either (1) or (2), the final period distribution, and (b) a redemption premium in an amount equal to $8.8007 per PHONES if we redeem prior to August 15, 2001, and that amount as successively reduced by $1.2280 per PHONES if we redeem prior to each following quarterly interest payment date through February 15, 2003, except that no amount referred to in this clause (b) will be payable in the event we redeem between February 6 and February 15, 2003. In addition, if the distribution date for any distribution of additional interest falls after the redemption date, we will make the distribution on the distribution date. Do the PHONES Have Anti-Dilution Protection For Changes in the Reference Shares? Yes. If specific dilutive or anti-dilutive events occur with respect to the reference shares, the number and type of the reference shares that will be used to calculate the amount you will receive upon exchange, redemption or maturity of the PHONES will be adjusted to reflect those events. These adjustments are described in this prospectus under the heading "Description of PHONES--Dilution Adjustments." Can You Exchange PHONES for McLeodUSA Stock? No. You may, however, exchange your PHONES for cash. When Can You Exchange the PHONES for Cash? At any time or from time to time, you may exchange your PHONES for an amount of cash per PHONES equal to a percentage (which we refer to as the early exchange ratio) of the then exchange market value of the reference shares attributable to each PHONES. The early exchange ratio is equal to (a) 95% of the then exchange market value of the reference shares or (b) during a deferral of the quarterly interest payments on the PHONES or, if we so elect, during the pendency of any tender or exchange offer for any of the reference shares, 100% of the then exchange market value of the reference shares. In addition, during the pendency of certain tender or exchange offers for any of the reference shares, if we have elected to increase the early exchange ratio, then we agree to also pay the other amounts described under the heading "Description of PHONES--Dilution Adjustments." Will the PHONES be Listed on a Stock Exchange? No. 9 What Form are the PHONES Issued? The PHONES are represented by one or more global securities deposited with and registered in the name of The Depository Trust Company of New York City ("DTC") or its nominee. This means you will not receive a certificate for your PHONES. What are the Federal Income Tax Consequences to You? The PHONES are characterized as indebtedness of ours for United States federal income tax purposes. Accordingly, you are required to include, in your income, interest with respect to the PHONES. Each PHONES constitutes a contingent payment debt instrument. As a result, you are required to include amounts in income, as ordinary income, in advance of the receipt of the cash attributable thereto. The amount of interest income required to be included by you for each year will be in excess of the quarterly interest payments you receive. Any gain recognized by you on the sale or exchange of a PHONES will be ordinary interest income; any loss will be ordinary loss to the extent of the interest previously included in income, and thereafter, capital loss. A summary of the United States federal income tax consequences of ownership of the PHONES is described in this prospectus under the heading "Certain United States Federal Income Tax Considerations." 10 General Indenture Provisions Applicable to the PHONES Certain Covenants.............. The Indenture (as defined on page 21) contains covenants that, among other things, limit our ability and that of our subsidiaries and, for some limited matters, Alliant Energy Corporation to: o issue, assume or guarantee certain additional secured indebtedness; o engage in sale and lease-back transactions; and o consolidate or merge. These covenants are subject to important exceptions and qualifications, which are described under the heading "Description of PHONES" in this prospectus. Events of Default.............. Each of the following is an event of default under the Indenture: o the failure by us or Alliant Energy Corporation to pay principal of or premium, if any, on the PHONES when due; o the failure by us or Alliant Energy Corporation for 30 days to pay interest when due on the PHONES, including basic interest, additional interest and amounts relating to cash dividends on the reference shares; o the failure by us or Alliant Energy Corporation to perform other covenants with respect to the PHONES following 90 days after receipt of notice of failure; and o certain events of bankruptcy, insolvency or reorganization of us or Alliant Energy Corporation. These covenants are subject to important exceptions and qualifications, which are described under the heading "Description of PHONES" in this prospectus. Remedies....................... If any event of default occurs and is continuing, the trustee under the Indenture or holders of at least 25% in aggregate principal amount of outstanding PHONES may declare the principal thereof immediately due and payable. Other.......................... The PHONES vote together as a single class for purposes of determining whether the holders of the requisite percentage in outstanding principal amount have taken certain actions or exercised certain rights under the Indenture. 11 Summary Financial Information Alliant Energy Resources, Inc.CONSOLIDATED RATIO OF EARNINGS TO FIXED CHARGES The following table sets forth our unaudited summaryshows Alliant Energy's consolidated financial information.

13 RISK FACTORS You should consider carefully, in additioneither case as provided under Section 180.0622(2)(b) of the Wisconsin Business Corporation Law. This provision of Wisconsin law provides that shareowners will be personally liable up to the other information contained and incorporated by reference in this prospectus, the following factors before purchasing the PHONES offered hereby. Return on the PHONES Depends on the McLeodUSA Stock The terms of the PHONES differ from those of ordinary debt securities because: o the interest payments on the PHONES may change depending upon the dividend policy of McLeodUSA or any other reference company; o the PHONES are exchangeable for cash in an amount based on the then exchange marketpar value of the reference shares; and oshares owned by them for all debts Alliant Energy owes to its employees for services performed for the contingent principal amountCompany not exceeding six months service in any one case. A Wisconsin trial court has interpreted "par value" to mean the subscription price paid for the shares rather than the lower stated par value. While the Wisconsin Supreme Court by an evenly divided vote affirmed the trial court's decision, that affirmation technically provides no precedential effect because of the PHONES willcourt's even decision. Alliant Energy's common stock is entitled to such dividends as may be adjusteddeclared from time to reflecttime by its board of directors in accordance with applicable law. Alliant Energy's ability to pay dividends is dependent upon a number of factors, including the accrual andability of its subsidiaries to pay dividends. Alliant Energy's utility subsidiaries each have restrictions on the payment of basic interest, payments on the PHONES in respect of regular cash dividends on their common stock based on their respective bond indentures, the reference sharesterms of their outstanding preferred stock and distributionsregulatory restrictions applicable to them. Only the holders of additional interest on the PHONES in respect of distributions of cash or property on the reference shares, and otherwise in the manner described in this prospectus. Changes in the contingent principal amount will not affect the amount of the quarterly payments of basic interest, of amounts relating to regular cash dividends on the reference shares, or of additional interest. Accordingly, the return that a holder of the PHONES will receive is not comparable to that of an ordinary fixed income debt security issued by us. The dividend policy of McLeodUSA is entirely outside of our control. As of the date of this prospectus, McLeodUSA has never paid a cash dividend on its McLeodUSA stock. You should not expect that McLeodUSA will commence paying dividends in the future or, if commenced, that the dividend rate on the McLeodUSA stock will remain the same during the period the PHONES are outstanding. It is impossible to predict whether the price of the McLeodUSA stock will rise or fall. Trading prices of the McLeodUSAcommon stock will be influenced by McLeodUSA's operating results and by complex and interrelated political, economic, financial and other factors that can affect the capital markets generally, the over-the-counter market and the market segments of which McLeodUSA is a part. In addition, the stock market in general, and the stocks of telecommunications and technology companies like McLeodUSA in particular, have experienced significant volatility. These broad market and industry fluctuations may adversely affect the trading price of the McLeodUSA stock. As of June 30, 2001, we beneficially owned approximately 56.1 million shares of McLeodUSA Class A Common Stock, $.01 par value per share. Our sales of the McLeodUSA stock are subjectentitled to certain restrictions and obligations under the Third Amended and Restated November 1998 Shareholders Agreement, dated as of March 10, 2000, as amended, and the Third Amended and Restated January 1999 Shareholders Agreement, dated as of March 10, 2000, as amended. Our obligations under those agreements do not affect our obligations under the PHONES. Even though not required, we have escrowed 15,634,230 shares of McLeodUSA stock and, subject to our stockholders' agreement relating to the McLeodUSA stock, we currently expect to sell those shares to raise the proceeds to pay the amount due upon exchange, maturity or redemption of the PHONES. Our Board of Directors can, however, release these escrowed shares with a supermajority vote. 14 Although we cannot assure you that these sales of the McLeodUSA stock will not adversely affect the marketvote for the McLeodUSA stock or the amount due upon exchange, maturity or redemptionelection of the PHONES, we have no reasonmembers to believe that any of these sales will have this effect. You should read McLeodUSA's publicly available documents for a discussion of the risks and uncertainties associated with McLeodUSA and the McLeodUSA stock. Fluctuations in the Market Value of the PHONES and the McLeodUSA Stock May Affect Our Reported Earnings On July 1, 2000, Alliant Energy Corporation adopted Statement of Financial Accounting Standards No. 133 ("SFAS 133"), Accounting for Derivative Instruments and Hedging Activities. SFAS 133 requires us to split the value of the PHONES into a debt component and a derivative component. The payment feature tied to the McLeodUSA stock is considered an embedded derivative under SFAS 133 that must be accounted for as a separate derivative instrument. Prior to the adoption of SFAS 133, changes in fair value of all of the McLeodUSA stock had been recorded in the accumulated other comprehensive income component of shareowners' equity on Alliant Energy Corporation's Consolidated Balance Sheets, as these securities had been classified as available-for-sale. With the adoption of SFAS 133, Alliant Energy Corporation designated 15.6 million shares of McLeodUSA stock as trading securities. Subsequent changes in the fair value of securities designated as trading securities are reflected as increases or decreases in Alliant Energy Corporation's net income. These trading gains or losses are expected to correspond with and substantially offset changes in the intrinsic value of the derivative component of the PHONES; however, there may be periods with significant non-cash increases or decreases to our net income pertaining to the PHONES and the related shares of McLeodUSA stock. McLeodUSA Has No Obligations With Respect to the PHONES In addition to our beneficial ownership of McLeodUSA common stock, we have contractual rights to designate one director to serve on McLeodUSA'sEnergy's board of directors and certain agreements between McLeodUSA andon all other matters. Holders of Alliant Energy's common stock are entitled to one vote per share of common stock held by them on all matters properly submitted to a vote of shareowners, subject to Section 180.1150 of the Wisconsin Business Corporation Law. See "- Statutory Provisions." Shareowners have no cumulative voting rights, which means that the holders of shares entitled to exercise more than 50% of the voting power are able to elect all of the directors to be elected. Alliant Energy's board of directors is divided into three classes, with staggered terms of three years each. All shares of common stock are entitled to participate equally in distributions in liquidation. Holders of common stock have no preemptive rights to subscribe for or purchase Alliant Energy's shares. There are no conversion rights, sinking fund or redemption provisions applicable to Alliant Energy's common stock. The transfer agent for Alliant Energy's common stock is Alliant Energy's Shareowner Services Department. Common Share Purchase Rights Alliant Energy Corporation's public utility operating companieshas entered into a rights agreement pursuant to which each outstanding share of its common stock, including those operating companies grant McLeodUSA accessshares being sold by Alliant Energy pursuant to certain towers, rights-of-way, conduitsthis prospectus, has attached a right to purchase one-half of one share of Alliant Energy's common stock. A right will also attach to each share of common stock that Alliant Energy subsequently issues prior to the expiration of the rights agreement. Under circumstances described below, the rights will entitle the holder of the rights to purchase additional shares of common stock. In this prospectus and poles in exchangeany accompanying prospectus supplement, unless the context requires otherwise, all references to Alliant Energy's common stock include the accompanying rights. 5 Currently, the rights are not exercisable and trade with the common stock. If the rights become exercisable, each full right, unless held by a person or group that beneficially owns more than 15% of Alliant Energy's outstanding common stock, will initially entitle the holder to purchase one half of one share of Alliant Energy's common stock at a purchase price of $95 per full share, or $47.50 per half share, subject to adjustment. The rights will become exercisable only if a person or group has acquired, or announced an intention to acquire, 15% or more of Alliant Energy's outstanding common stock. Under some circumstances, including the existence of a 15% acquiring party, each holder of a right, other than the acquiring party, will be entitled to purchase at the right's then-current exercise price, shares of Alliant Energy's common stock having a market value of two times the exercise price. If another corporation acquires Alliant Energy after a party acquires 15% or more of Alliant Energy's common stock, each holder of a right will be entitled to receive the acquiring corporation's common shares having a market value of two times the exercise price. The rights may be redeemed at a price of $0.001 per right until a party acquires 15% or more of Alliant Energy's common stock and, after that time, may be exchanged for capacityone share of Alliant Energy's common stock per right until a party acquires 50% or more of Alliant Energy's common stock. The rights expire on McLeodUSA's communications network. Although weJanuary 20, 2009, subject to extension. Under the rights agreement, Alliant Energy's board of directors may reduce the thresholds applicable to the rights from 15% to not less than 10%. The rights do not have voting or dividend rights and, until they become exercisable, have no reasondilutive effect on Alliant Energy's earnings. Statutory Provisions Because Alliant Energy is a public utility holding company under the Public Utility Holding Company Act of 1935, the SEC must approve the acquisition of any of Alliant Energy's securities or utility assets by a registered public utility holding company or any person who would, as a result of such acquisition, become an affiliate of two or more public utility companies. Similarly, Section 196.795(3) of the Wisconsin Statutes provides that no person may hold or acquire, directly or indirectly, more than 10% of the outstanding securities of a public utility holding company such as Alliant Energy without the approval of the Public Service Commission of Wisconsin. Section 180.1150 of the Wisconsin Business Corporation Law provides that the voting power of public Wisconsin corporations such as Alliant Energy held by any person or persons acting as a group in excess of 20% of Alliant Energy's voting power is limited to believe10% of the information concerning McLeodUSA includedfull voting power of those shares, unless full voting power of those shares has been restored pursuant to a vote of shareowners. Sections 180.1140 to 180.1144 of the Wisconsin Business Corporation Law contain some limitations and special voting provisions applicable to specified business combinations involving Wisconsin corporations such as Alliant Energy and a significant shareholder, unless the board of directors of the corporation approves the business combination or referredthe shareholder's acquisition of shares before these shares are acquired. Similarly, Sections 180.1130 to 180.1133 of the Wisconsin Business Corporation Law contain special voting provisions applicable to some business combinations, unless specified minimum price and procedural requirements are met. Following commencement of a takeover offer, Section 180.1134 of the Wisconsin Business Corporation Law imposes special voting requirements on share repurchases effected at a premium to the market and on asset sales by the corporation, unless, as it relates to the potential sale of assets, the corporation has at least three independent directors and a majority of the independent directors vote not to have the provision apply to the corporation. 6 DESCRIPTION OF THE DEBT SECURITIES The following description of the terms of Resources' debt securities summarizes general terms and provisions that apply to the debt securities. Resources will describe the particular terms of any debt securities more specifically in the prospectus supplement relating to those debt securities. Resources will indicate in the prospectus supplement whether the general terms and provisions described in this prospectus is not reliable, we do not warrant that events have not occurred, which are not yet publicly disclosed by McLeodUSA, that would affect either the accuracy or completeness of the information concerning McLeodUSA included or referred to in this prospectus. McLeodUSA is not involved in the offering of the PHONES and has no obligations with respect to the PHONES, including any obligation to take our interests (other than as a holder of the McLeodUSA stock) or your interests into consideration for any reason or under any circumstance. McLeodUSA did not receive any of the proceeds of the original offering of the PHONES, will not receive any proceeds of the resale of the PHONES from any security holder and was not responsible for, and did not participate in, determining the timing of, prices for or quantities of the PHONES originally offered or those resold hereby. McLeodUSA is not involved with the administration, marketing or trading of the PHONES nor in the preparation of this prospectus and has no obligations with respect to the amount to be paid to holders of the PHONES upon exchange, maturity or redemption. Holders of the PHONES are not entitled to any rights with respect to the McLeodUSA stock other than indirectly pursuant to the express terms of the PHONES. 15 Basic Interest May be Deferred We can defer quarterly basic interest payments on the PHONES as many times as we want beginning after the February 15, 2003 payment, but only for up to 20 consecutive quarterly periods. We cannot defer payments in respect of regular cash dividends or additional interest distributions at any time, and we cannot defer quarterly basic interest payments if an event of default under the PHONES has occurred and is continuing. A deferral of basic interest payments cannot extend beyond the maturity date of the PHONES. If we defer quarterly basic interest payments, the contingent principal amount of the PHONES will be increased by the amount of the deferred quarterly basic interest payments, plus accrued interest thereon, at an annual rate equal to 2.50%, compounded quarterly at that rate, and the early exchange ratio (as defined on page 9) will be 100% of the reference shares for the quarter following each deferral of a payment of quarterly basic interest. Once we have paid all deferred quarterly basic interest, plus accrued interest thereon, together with the quarterly basic interest payment for the current quarterly interest payment period, the contingent principal amount will be reduced by the amount of that payment of deferred quarterly basic interest plus accrued interest thereon, the early exchange ratio will change to 95% of the reference shares, and we can again defer quarterly basic interest payments as described above. The Number of Reference Shares Attributable to Each PHONES Will Not Adjust for Some Dilutive Transactions Involving the Reference Shares If specific dilutive or anti-dilutive events occur with respect to the reference shares, the number and type of reference shares that will be used to calculate the amount you will receive upon exchange, maturity or redemption of a PHONES will be adjusted to reflect such events. These adjustments will not take into account various other events, such as offerings of the reference shares for cash or business acquisitions by a reference company with the reference shares, that may adversely affect the price of the reference shares and may adversely affect the trading price of and market value of the PHONES. We cannot assure you that a reference company will not make offerings of the reference shares or other equity securities or enter into such business acquisitions in the future. See "Description of PHONES--Dilution Adjustments" in this prospectus. The PHONES are Unsecured Obligations That Rank Equally With Existing and Future Additional Senior Indebtedness Neither the PHONES nor the Indenture under which the PHONES were issued limit our or our subsidiaries' ability to incur additional senior indebtedness, or to grant liens on assets to secure indebtedness, to pay dividends or to repurchase shares of capital stock. The Indenture does not contain any provisions specifically intended to protect holders of the PHONES in the event of a sudden and significant decline in our credit quality or a highly leveraged transaction involving us, including a change of control, or other similar transaction that may adversely affect holders of the PHONES. The PHONES are not Secured by any of Our Assets, Including the Shares of McLeodUSA Stock That We Currently Own The PHONES are not secured by any of our assets, including our shares of McLeodUSA stock, or the assets of Alliant Energy Corporation. The PHONES are, however, unconditionally guaranteed by Alliant Energy Corporation. The PHONES are our senior debt that ranks equal to our $250 million 7 3/8% Senior Notes due 2009, which we issued in November 1999 and exchanged for replacement notes in May 2000. 16 Potential Adverse Tax Consequences of Purchasing the PHONES If you are considering purchasing the PHONES, you should reach an investment decision only after consulting with your advisors as to the suitability of an investment in the PHONES in light of your particular circumstances. You should also consider the tax consequences of investing in the PHONES. The amount of interest income required to be included by you for each year will be in excess of the quarterly interest payments you actually receive. As a result, you will be required to include amounts in income as ordinary income, in advance of the receipt of the related cash. Any gain recognized by you on the sale or exchange of the PHONES will be ordinary interest income; any loss will be ordinary loss to the extent of the interest previously included in income, and thereafter, capital loss. See "Certain United States Federal Income Tax Considerations." 17 PRICE RANGE AND DIVIDEND HISTORY OF THE MCLEODUSA STOCK The McLeodUSA stock is listed and traded on The Nasdaq Stock Market under the symbol "MCLD."

We will not receive any cash proceeds from the resale of the PHONES by the selling security holders. 19 DESCRIPTION OF OUTSTANDING INDEBTEDNESS The following is information concerning our indebtedness other than the PHONES. We are a partyapply to a revolving 3-Year Credit Agreement with various banking institutions. This agreement extends through October 2003, with one-year extensions available upon agreement by the parties. We also use unused borrowing availability under this agreement to support our commercial paper program. A combined maximum of $450 million of borrowings under this agreement and commercial paper backed by this facility may be outstanding at any time. Interest rates and maturities are set at the time of borrowing. The rates are based upon quoted market prices and the maturities are less than one year. At March 31, 2001, we had no direct borrowings under this facility and $418 million of commercial paper outstanding and backed by this facility, with interest rates ranging from 4.90% to 6.37% and maturities ranging from six to 54 days. We intend to continue issuing commercial paper backed by this facility. At March 31, 2001, we had $32 million of credit capacity available under this facility. No conditions existed at March 31, 2001 that would prevent the issuance of commercial paper or direct borrowings under the 3-Year Credit Agreement. We are also a party to a revolving 364-Day Credit Agreement with various banking institutions. This agreement extends through October 15, 2001, with 364-day extensions available upon agreement by the parties. We also use the unborrowed portion of this agreement to support our commercial paper program. A combined maximum of $150 million of borrowings under this agreement and commercial paper backed by this facility may be outstanding at any one time. Interest rates and maturities are set at the time of borrowing. The rates are based upon quoted market prices and the maturities are less than one year. At March 31, 2001, we had no borrowings under this facility and no commercial paper backed by this facility outstanding and we had $150 million of credit capacity available under this facility. No conditions existed at March 31, 2001 that would prevent the issuance of commercial paper or direct borrowings under the 364-Day Credit Agreement. In November 1999, we completed a private placement of $250,000,000 of our 7-3/8% Senior Notes due 2009 in accordance with Rule 144A under the Securities Act of 1933. Alliant Energy Corporation has agreed to fully and unconditionally guarantee the payment of principal and interest on the 7-3/8% Senior Notes. In May 2000, we exchanged new registered 7-3/8% Senior Notes due 2009 for all our outstanding unregistered 7-3/8% Senior Notes due 2009. Both series of 7-3/8% Senior Notes were issued asparticular series of debt under the same indenture that the PHONES were. The 7-3/8% Senior Notes mature on November 9, 2009 and rank equally with the PHONES. 20 DESCRIPTION OF PHONES The PHONES were issued as asecurities. Resources will issue, in one or more series, of debt securities under and governed by an Indenture,indenture, dated as of November 4, 1999, as supplementedbetween Resources and amended by the First Supplemental Indenture, dated as of November 4, 1999, and by the Second Supplemental Indenture dated February 1, 2000 creating the PHONES (the Second Supplemental Indenture is referred to herein as the "Supplemental Indenture," and collectively with the Indenture and the First Supplemental Indentures as the "Indenture"), between us and FirstarU.S. Bank, N.A., as trustee and paying agent, (the "Trustee"). The followingas supplemented and amended from time to time. This indenture, as supplemented and amended, is referred to in this prospectus as the indenture. This section briefly summarizes the indenture. Since this is only a summary, of certain provisionsit does not contain all of the Indenture, the PHONESinformation that may be important to you. The summary is subject to and the guarantee is not complete, and is qualified in its entirety by reference to the provisionsindenture which is filed as an exhibit to the registration statement of which this prospectus is a part and incorporated by reference into this prospectus. See "Where You Can Find More Information." Parenthetical section references under this heading are references to sections of the Indenture. The Indenture is not qualified as an indenture under the Trust Indenture Act of 1939. Copies of the Indenture are available for inspection on any business day during normal business hours at the office of the Trustee in Milwaukee, Wisconsin or New York, New York. The holders of PHONES are entitled to the benefits of, are bound by, and are deemed to have notice of, all the provisions of the Indenture. Wherever defined terms of the Indenture are referred to, such defined terms are incorporated herein by reference.indenture. General The Indentureindenture does not limit the aggregate principal amount of debt securities that Resources may be issued thereunderissue and provides that it may issue debt securities may be issuedunder the indenture from time to time in one or more series as provided in a supplemental indenture or Board Resolution. The PHONES are unconditionally guaranteed by Alliant Energy Corporation, were initially limiteda resolution of its board of directors. (Section 2.1). Resources will describe in each prospectus supplement the following terms that apply to 5,940,960 PHONES and mature on February 15, 2030. Asthe debt securities offered under that prospectus supplement: o the title of the date hereof,series of debt securities; o any limit on the only debt securities outstanding under the Indenture are $250 million aggregate principal amount of our 7 3/8% Senior Notes due 2009 (whether initial issuance or issued on registered exchange therefore). The provisionsthe debt securities of the Indenture described below are also generally applicableseries; o the dates on which Resources must pay principal; o the rates at which the debt securities will bear interest or the manner in which interest will be determined, if any interest is payable; o the dates from which any interest will accrue, the dates on which Resources must pay interest and the record date for determining who is entitled to our senior notes. Interest Weany interest payment; o the places where Resources must pay the debt securities; o the terms and conditions on which Resources may redeem the debt securities; o the terms and conditions of any sinking fund; o if other than denominations of $1,000 and integral multiples thereof, then the denominations in which Resources may issue the debt securities; o if other than the principal amount of the securities, then the amount Resources will pay if the maturity of the debt securities is accelerated; o whether the debt securities will be issued as securities registered with the registrar, not registered with the registrar or both; o whether Resources will issue the debt securities in the form of one or more global securities and, if so, the identity of the depository for the global security or securities; 7 o if other than the currency of the United States, then the currencies, or composite currencies, in which the debt securities will be denominated and in which Resources will make quarterly basic interest payments in an amount equal to $1.2280 per PHONES, reflecting a basic interest rate of 7.25% per year on the originaldebt securities; o if Resources or a holder may elect to have the principal amount, through February 15, 2003, and thereafter in an amount equal to $.4234 per PHONES, reflecting a basic interest rate of 2.50% per year on the original principal amount, in each case plus the amount of any regular cash dividends paid on the reference shares attributable to each PHONES. Interest on the PHONES is paid quarterly in arrears on February 15, May 15, August 15 and November 15 of each year, to holders of record at the close of business on February 1, May 1, August 1 or November 1, as the case may be, immediately preceding that payment date whether or not a business day, but subject to our right to defer quarterly payments of basic interest beginning after the February 15, 2003 payment. When we refer in this prospectus to the basic interest on the PHONES atdebt securities be payable in a particular time, we meancurrency other than the basicsecurities' stated currency, then the terms of such election; o if the principal or interest as computed atpayable is determined with reference to an index based on currency other than the basic ratedebt securities' stated currency, then the manner in effect at that time. We will also distribute to you, as additional interest onwhich the PHONES, any property, including cash (other than any regular cash dividends), distributed on or with respect to the reference shares (other than publicly traded equity securities, which will themselves become reference shares). If the additional interest on the reference shares includes publicly traded securities (other than equity securities) that can be transferred by us to you without registration under the federal securities laws and without breach of our contractual arrangements with McLeodUSA, and thatamounts will be freely transferable in your hands, then we will distribute those securities to you. We will not, however, distribute fractional units of securities to you. We will pay you 21 cash instead of distributing the fractional units. Otherwise, we will distribute to you the then fair market value of any property comprising additional interest, including publicly traded securities not meeting the standards set forth above, as determined in good faith by our board of directors. We will distribute any additional interest to holders of the PHONES within 20 business days after it is distributed to us. The record date for any distribution of additional interest will be the 10th business day after the date any cash or property is distributed to us. The contingent principal amount for each PHONES will be increased during each quarter, based on the contingent principal amount at the beginning of the quarter, by an amount equal to interest accrued on that beginning contingent principal amount at the basic interest rate on the PHONES then in effect, and will be reduced by the following amounts on the dates they are paid to holders of the PHONES: o the quarterly basic interest payment made on the PHONES; o any amounts paid on the PHONES in respect of regular cash dividends paid on the reference shares during the quarter;determined; and o any amounts paid onother terms of the PHONESdebt securities and any other deletions from or modifications or additions to the indenture in respect of the amountdebt securities. (Section 2.2). Alliant Energy Guarantee Alliant Energy has agreed under the indenture to fully and unconditionally guarantee the payment of the fair market valueprincipal of, any additional interest payments made during the quarter. As a result, the quarterly computations of the contingent principal amount will be made such that the yield to each date of computation (including all quarterly basic interest, all amounts paid in respect of regular cash dividends on the reference shares, and the fair market value of any additional interest payments) does not exceed a 7.25% annual yield, if such date of computation is on or before February 15, 2003, or the weighted average of a 7.25% annual yield through February 15, 2003, and of a 2.50% annual yield thereafter, if such date of computation is after November 15, 2002. Notwithstanding the foregoing, in the event that we redeem the PHONES on a date which is between February 6 and February 15, 2003, the contingent principal amount will not be increased by an amount equal to the interest accrued on the beginning contingent principal amount for the quarterly interest payment period beginning on November 15, 2002. In no event will the contingent principal amount be less than zero. Changes in the contingent principal amount will not affect the amount to be paid to holders of PHONES in respect of the quarterly interest payments of basic interest, amounts relating to regular cash dividends on the reference shares, or additional interest. If basic interest or additional interest is payable on a date that is not a business day (as defined at the end of this paragraph), payment will be made on the next business day (and without any interest or other payment in respect of this delay). A "business day" means any day that is not a Saturday, a Sunday or a legal holiday or a day on which banking institutions or trust companies in the City of New York are authorized or obligated by law to close. Principal, premium, if any, and interest or distributions on, the PHONES will bedebt securities as these items become due and payable, whether at the officematurity, upon redemption or agency we maintain for such purpose within the City and State of New York or, at our option, payment of interest may be made by check mailedotherwise, according to the holdersterms of the PHONESdebt securities and the indenture. Alliant Energy will determine, at their respective addresses set forth in the register of holders of the PHONES. Until we otherwise designate, our office or agency in New York will be the office of the trustee maintained for that purpose. The PHONES have been issued in denominations ofleast one PHONES and integral multiples thereof. 22 Deferral of Interest Payments If no event of default has occurred and is continuing under the PHONES, we can, on one or more occasions beginning after the February 15, 2003 payment, defer quarterly basic interest payments on the PHONES for up to 20 consecutive quarterly periods. If we terminate a deferral period and subsequently elect to defer quarterly basic interest payments, we will again be subjectbusiness day prior to the 20 consecutive quarterly period limitation. Any deferral of basic interest payments cannot extend, however, beyond the maturity date of the PHONES. We can never defer distributions of additional interest or quarterly payments equal to regular cash dividends paid on the maximum number of reference shares. If we defer quarterly payments of basic interest, the contingent principal amount of the PHONES will increase by the amount of the deferred quarterly payments of basic interest, plus accrued interest thereon at an annual rate equal to 2.50%, compounded quarterly, and the early exchange ratio will be 100% of the reference shares for the quarter following each deferral ofupon which a payment of quarterly interest. Once we have paid all deferred quarterly basicprincipal of, and premium, if any, or interest plus accrued interest thereon, together withon, any series of debt securities is due and payable, whether Resources has available the quarterly basic interest payment for the current quarterly interest payment period, the contingent principal amount will be reduced by the amount of that payment of deferred quarterly basic interest plus accrued interest thereon, the early exchange ratio will changefunds to 95% of the reference shares, and we can again defer quarterly basic interestmake these payments as described above.they become due and payable. If we electResources fails to defer basicpay principal, premium, if any, or interest, on the PHONES in any particular quarter, wethen Alliant Energy will give the trustee notice. We will also prepare a press releasecause these payments to be made as they become due and provide it to DTC for dissemination through the DTC broadcast facility. We will give this notice one business day before the earlier of: o the record date for the next date that interest on the PHONES is payable; or o the date we are required to give notice to The Nasdaq Stock Market (or any other applicable self-regulatory organization) or to holders of the PHONES as of the record date or the date any quarterly interest payment is payable. We refer to the last date on which we can give notice that we intend to defer the payment of basic interest in respect of a quarterly payment of interest as a deferral notice date. We have no current intention of deferring basic interest payments on the PHONES. Principal Amount The original principal amount per PHONES is equal to $67.75. The minimum amount payable, whether at maturity, upon redemption, or maturityotherwise, as if these payments were made by Resources. Alliant Energy's obligations will be unconditional regardless of the validity or enforceability of, or the absence of any action to enforce, the debt securities or the indenture, any waiver or consent by a holder of debt securities, the recovery of any judgment against Resources or any action to enforce a judgment against Resources. Alliant Energy will be subrogated to all rights of a PHONES (which we referholder of debt securities against Resources with respect to as the contingent principal amount) was $67.75 as of May 15, 2001. The contingent principal amount for each PHONES will be increased during each quarter, based on the contingent principal amount at the beginning of the quarter, by an amount equal to interest accrued on that beginning contingent principal amount at the basic interest rate on the PHONES then in effect, and on the dates the following amounts are paid to holders of the PHONES, will be reduced by: o the quarterly basic interest payment made on the PHONES; o any amounts paid on the PHONES in respect of regular cash dividends paid on the reference shares during the quarter; and 23 o any amounts paid on the PHONES in respect of the market value of any additional interest payments made during the quarter. Notwithstanding the foregoing, in the event that we redeem the PHONES on a date which is between February 6 and February 15, 2003, the contingent principal amount will not be increased by an amount equalAlliant Energy pursuant to the interest accrued on the beginning contingent principal amount for the quarterly interest payment period beginning on November 15, 2002. In no event will the contingent principal amount be less than zero. If the contingent principal amount is reduced to zero or if all of the reference shares cease to be outstanding as a result of a tender offer, an exchange offer, a business combination or otherwise, the maturity of the PHONES will not be accelerated, the PHONES will continue to remain outstanding until the maturity date unless earlier redeemed by us, and you will receive the contingent principal amount, if any, on the redemption date or the maturity date. At maturity you will be entitled to receive the higher of (a) the contingent principal amount of the PHONES or (b) the sum of the then current market value (as defined on page 26) of the reference shares on the maturity date plus any deferred quarterly payments of basic interest (including any accrued interest thereon), plus, in the case of either (a) or (b), the final period distribution. In addition, if the distribution date for any distribution of additional interest falls after the maturity date, we will make the distribution on the distribution date. A "final period distribution" means, in respect of (a) the maturity date, a distribution determined in accordance with clauses (2), (3) and (4) below, and (b) the redemption date, a distribution determined in accordance with clauses (1), (2), (3) and (4) below. If the redemption date is in connection with a rollover offering, the distribution determined in accordance with clause (4) shall be all dividends and distributions on or in respect of the reference shares on the pricing date (defined below) would be entitled to receive. (1) Unless (a) the redemption date of the PHONES is also a quarterly interest payment date or (b) quarterly interest has been deferred for the then current quarterly dividend period, an amount equal to the basic annual interest rate on the PHONES accrued on the original principal amount of the PHONES from the most recent interest payment date to the date of redemption, or to the date of the next quarterly interest payment date in the case of a redemption of the PHONES on a date which is between February 6 and February 15, 2003, plus (2) a distribution equal to the sum of all dividends and distributions on or in respect of the reference shares declared by the applicable reference company and for which the ex-date for the dividend or distribution falls during the period from the date we issue the PHONES to the most recent interest payment date and which have not been distributed to holders of reference shares prior to the most recent interest payment date, plus (3) a distribution equal to the sum of all dividends and distributions on or in respect of the reference shares which a holder of reference shares on the latest ex-date for a dividend or distribution occurring during the period from the most recent quarterly interest payment date to the date immediately preceding the first trading day of the averaging period (as defined below) is entitled to receive, plus 24 (4) a distribution equal to the sum of, for each successive day in the averaging period that is anticipated on the first day of the averaging period to be a trading day, the amounts determined in accordance with the following formula: E x (1-0.05n) where: E = all dividends and distributions on or in respect of the reference shares which a holder of the reference shares on the applicable day would be entitled to receive, provided that the ex-date for the dividend or distribution date that occurs on a day that is not a scheduled trading day shall be deemed to have occurred on the immediately preceding scheduled trading day; and n = the number of scheduled trading days that have elapsed in the averaging period with the first trading day of the averaging period being counted as zero. A holder of the PHONES is only entitled to receive distributions determined in accordance with clauses (2), (3) or (4) to the extent actually distributed by the applicable reference company. Cash amounts paid by the applicable reference company on reference shares as described in clauses (2), (3) or (4) before the redemption date or the maturity date, as the case may be, will be paid on the redemption date or the maturity date, as the case may be. All other property distributed, or the cash value of the property, will be distributed within 20 business days after it is distributed to us. Exchange Option You may at any time or from time to time exchange a PHONES for an amount of cash equal to a percentage of the then exchange market value of the reference shares attributable to each PHONES (which we refer to as the early exchange ratio). The early exchange ratio will be equal to: o 95% of the then exchange market value of the reference shares attributable to each PHONES; or o during a deferral of the quarterly interest payments on the PHONES or, if we so elect, during the pendency of any tender or exchange offer for any of the reference shares, 100% of the then exchange market value of the reference shares attributable to each PHONES. We will pay you the amount due upon exchange as soon as reasonably practicable after you deliver an exchange notice to the trustee, but in no event earlier than three trading days after the date of your notice or later than 15 trading days after the date of your notice. The "exchange market value" means the closing price (as defined below) on the trading day (as defined below) following the date you deliver an exchange notice to the trustee, unless more than 200,000 PHONES have been delivered for exchange on that date. If more than 200,000 PHONES have been delivered for exchange, then the exchange market value shall be the average closing price on the five trading days following that date. If more than 200,000 PHONES are delivered for exchange on any one day, we will give the trustee notice. We will also issue a press release prior to 9:00 a.m. New York City time on the next trading day, and provide it to DTC for dissemination through the DTC broadcast facility. Our failure to provide this notice, however, will not affect the determination of exchange market value as described above. 25 So long as the PHONES are held through The Depository Trust Company of New York City ("DTC"), you may exercise your exchange right through the relevant direct participant in the DTC ATOP system. If the PHONES are held in certificated form, you may exercise your exchange right as follows: o complete and manually sign an exchange notice in the form available from the trustee and deliver this notice to the trustee at the office maintained by the trustee for this purpose; o surrender the PHONES to the trustee; o if required, furnish appropriate endorsement and transfer documents; and o if required, pay all transfer or similar taxes. Pursuant to the indenture, the date on which all of the foregoing requirements have been satisfied is the redemption date with respect to the PHONES delivered for exchange. As of June 30, 2001, we beneficially owned approximately 56.1 million shares of McLeodUSA stock. We may, but are not required to, hold a number of shares of the McLeodUSA stock equal to the number of the PHONES outstanding until maturity or redemption of the PHONES and, subject to our stockholders agreement concerning the McLeodUSA stock, sell those shares to raise the proceeds to pay the amount due upon exchange, maturity or redemption of the PHONES. Although we cannot assure you that these sales of the McLeodUSA stock will not adversely affect the market for McLeodUSA stock or the amount due upon exchange, maturity or redemption, we have no reason to believe that any of these sales will have this effect. Redemption We may redeem at any time all but not some of the PHONES at a redemption price equal to the sum of (a) the higher of (1) the contingent principal amount of the PHONES or (2) the sum of the then current market value of the reference shares on the redemption date plus any deferred quarterly payment of interest (including any accrued interest thereon), plus, in the case of either (1) or (2), the final period distribution, and (b) a redemption premium in an amount equal to $8.8007 per PHONES if we redeem prior to the quarterly interest payment date on August 15, 2001, and that amount as successively reduced by $1.2280 per PHONES if we redeem prior to each following quarterly interest payment date through the quarterly interest payment date on February 15, 2003, except that no amount referred to in this clause (b) will be payable in the event we redeem between February 6 and February 15, 2003. In addition, if the distribution date for any distribution of additional interest falls after the redemption date, we will make the distribution on the distribution date. The "current market value" (other than in the case of a rollover offering, which is described below) is defined as the average closing price per reference share on the 20 trading days (which we refer to as the averaging period) immediately prior to (but not including) the fifth business day preceding the maturity date or the redemption date, as the case may be; provided, however, that for purposes of determining the payment required upon redemption in connection with a rollover offering, "current market value" means the closing price per reference share on the trading day immediately preceding the date that the rollover offering is priced (which we refer to as the pricing date) or, if the rollover offering is priced after 4:00 p.m., New York City time, on the pricing date, the closing price per share on the pricing date, except that if there is not a trading day immediately preceding the pricing date or (where pricing occurs after 4:00 p.m., New York City time, on the pricing date) if the pricing date is not a trading day, "current market value" means the market value per reference share as of the redemption date as determined by a nationally recognized independent investment banking firm retained by us. 26 A "rollover offering" means a refinancing of the PHONES by way of either (a) a sale of the reference shares or (b) a sale of securities that are priced by reference to the reference shares, in either case, by means of a completed public or private offering or offerings by us and which is expected to yield net proceeds which are sufficient to pay the redemption amount for all of the PHONES. The trustee will notify you if we elect to redeem your PHONES in connection with a rollover offering not less than 30 nor more than 60 business days prior to the redemption date. We will also issue a press release prior to 4:00 p.m., New York City time, on the business day immediately before the day on which the closing price of the reference shares is to be measured for the purpose of determining the current market value in connection with a rollover offering. The notice will state we are firmly committed to price the rollover offering, will specify the date on which the rollover offering is to be priced (including whether the rollover offering will be priced during trading on the pricing date or after the close of trading on the pricing date) and consequently, whether the closing price for the reference shares by which the current market value will be measured will be the closing price on the trading date immediately preceding the pricing date or the closing price on the pricing date. We will provide that press release to DTC for dissemination through the DTC broadcast facility. The "closing price" of any security on any date of determination means the closing sale price (or, if no closing sale price is reported, the last reported sale price) of that security (regular way) on The Nasdaq Stock Market on that date or, if that security is not listed for trading on The Nasdaq Stock Market on that date, as reported in the composite transactions for the principal United States securities exchange on which that security is so listed, or if that security is not so listed on a United States national or regional securities exchange, the last quoted bid price for that security in the over-the-counter market as reported by the National Quotation Bureau or similar organization. In the event that no such quotation is available for any day, our board of directors will be entitled to determine the closing price on the basis of those quotations that it in good faith considers appropriate. To the extent that trading of reference shares normal way continues past 4:00 p.m., New York City time, "closing price" shall be deemed to refer to the price at the time that is then customary for determining the trading day's index levels for stocks traded on the primary national securities exchange or automated quotation system on which the reference shares are then traded or quoted. All references to 4:00 p.m., New York City time, in the definition of "current market value" shall thereafter be deemed to refer to the then customary determination time. A "trading day" is defined as a day on which the security, the closing price of which is being determined, (a) is not suspended from trading on any national or regional securities exchange or association or over-the-counter market at the close of business and (b) has traded at least once on the national or regional securities exchange or association or over-the-counter market that is the primary market for the trading of that security. We will give you 30 business days' notice before the redemption of the PHONES and will irrevocably deposit with the trustee sufficient funds to pay the redemption amount. Distributions to be paid on or before the redemption date of the PHONES will be payable to the holders on the record dates for the related dates of distribution. Once notice of redemption is given and funds are irrevocably deposited, interest on the PHONES will cease to accrue on and after the date of redemption and all rights of the holders of the PHONES will cease, except for the right of the holders to receive the redemption amount (but without interest on that redemption amount). If the redemption date is not a business day, then the redemption amount will be payable on the next business day (and without any interest or other payment in respect of that delay). 27 If we improperly withhold or refuse to pay the redemption amount for the PHONES, interest on the PHONES will continue to accrue at an annual rate equal to the basic rate of interest then in effect, even if such rate is lower than the rate in effect when the amount owed originally accrued, from the original redemption date to the actual date of payment. In this case, the actual payment date will be considered the redemption date for purposes of calculating the redemption amount. The final period distribution will be deemed paid on the original redemption date to the extent paid as set forth in the definition of final period distribution above. In compliance with applicable law (including the U.S. securities laws), we and our affiliates may, at any time, purchase outstanding PHONES by tender offer, in the open market or by private agreement.guarantee. Ranking The PHONES are ourdebt securities will be senior, unsecured and unsubordinated obligations of Resources, ranking equally and ratably with all ourits other senior, unsecured and unsubordinated obligations. The PHONES are unconditionally guaranteed by Alliant Energy Corporation. The guarantees are unsecured obligations of Alliant Energy Corporation and rank equally with all other unsecured and unsubordinated indebtedness of Alliant Energy Corporation. Because we areResources is a holding company and conductconducts substantially all of ourits operations through ourits subsidiaries, the rights of ourits creditors, including those under the PHONES,debt securities, to participate in any distributions of the assets of any of ourResources' subsidiaries or joint ventures, upon liquidation or reorganization or otherwise, are necessarily subject, and therefore arewill be effectively subordinated, to the prior claims of creditors of any of ourResources' subsidiaries or joint ventures, (including trade creditors and holders of indebtedness issued by such subsidiary or joint venture), except to the extent ourResources' claims as a creditor may be recognized. In addition, becausethe guarantees will be unsecured obligations of Alliant Energy Corporationand will rank equally with all other unsecured and unsubordinated indebtedness of Alliant Energy.

Resources may designate additional paying agents, rescind the designation of any paying agent or 8 approve a change in the office through which any paying agent acts, but Resources must maintain a paying agent in each place where payments on the debt securities are payable. (Section 2.04). Resources may pay interest on debt securities it issues in registered form by check mailed to the address of the persons entitled to a claim against usthe payments. Resources will pay interest on debt securities issued in an amount equalregistered form on any interest payment date to the higher of (a) the contingent principal amountregistered owners of the PHONES or (b)debt securities at the sumclose of business on the regular record date for the interest payment date.

(Section 4.05). Purchase and Cancellation Resources may at any time purchase debt securities in the open market value (without giving effector otherwise at any price, subject to applicable U.S. securities laws.

U.S. Federal Income Tax Considerations Resources may issue the debt securities as original issue discount securities, bearing no interest or bearing interest at a rate, which, at the time of issuance, is below market rates, to be sold at a substantial discount below their principal amount. Resources will describe some special U.S. federal income tax and other considerations applicable to any deferred quarterly payments of interest (including any accrued interest thereon), plus,debt securities that are issued as original issue discount securities in the caseapplicable prospectus supplement.

Dilution Adjustments For purposes of this offering memorandum, "reference company" means McLeodUSA and any other issuer of a reference share. A "reference share" means, collectively: 28 o currently, 2.6316 shares of McLeodUSA stock; o each share or fraction of a share of publicly traded equity securities received by a holder of a reference share in respect of that reference share, and, to the extent the reference share remains outstanding after any of the following events but without duplication, including the reference share, in each case directly or as the result of successive applications of this paragraph upon any of the following events: o the distribution on or in respect of a reference share in reference shares; o the combination of reference shares into a smaller number of shares or other units; o the subdivision of outstanding shares or other units of reference shares; o the conversion or reclassification of reference shares by issuance or exchange of other securities; o any consolidation or merger of a reference company, or any surviving entity or subsequent surviving entity of a reference company (which we refer to as a reference company successor), with or into another entity (other than a merger or consolidation in which the reference company is the continuing corporation and in which the reference company common stock outstanding immediately prior to the merger or consolidation is not exchanged for cash, securities or other property of the reference company or another corporation); o any statutory exchange of securities of the reference company or any reference company successor with another corporation (other than in connection with a merger or acquisitionrestrictions, elections, some U.S. federal income tax considerations, specific terms and other than a statutory exchange ofinformation about the debt securities in whichand the reference company is the continuing corporation and in which the reference company common stock outstanding immediately prior to the statutory exchange is not exchanged for cash, securitiesforeign currency or other property of the reference company or another corporation); or o any liquidation, dissolution or winding up of the reference company or any reference company successor; and o a reference share as adjusted by any reference share offer adjustment. As described above under "Interest," we will pay as additional interest to holders of the PHONES any property received in distribution on a reference share, unless it is also a reference share, in which case it shall become part of a reference share. Upon any distribution of fractional shares or units of securities, other than fractional reference shares, we will pay the holders cash in lieu of distribution of such fractional shares or other units. A "reference share offer" means any tender offer or exchange offer made for all or a portion of a class or series of reference shares of a reference company. If a reference share offer is made, we will, at our option, either: o during the pendency of the offer, increase the early exchange ratio to 100% of the reference shares and, if we exercise this option prior to February 15, 2003, agree to pay to each 29 exchanging PHONES holder an amount equal to the redemption premium (as described above under "--Redemption") that would be owed to that holder if we had redeemed the PHONES on the date of exchange; or o make a reference share offer adjustment. A "reference share offer adjustment" means including as part of a reference share each share of publicly traded equity securities, if any, deemed to be distributed on or in respect of a reference share as average transaction consideration less the reference share proportionate reduction (as defined below). The average transaction consideration deemed to be received by a holder of one reference share in a reference share offer will be equal to (a) the aggregate consideration actually paid or distributed to all holders of reference shares that participatedcomposite currencies in the reference share offer, divided by (b) the total number of reference shares outstanding immediately prior to the expiration of the reference share offer and entitled to participate in that reference share offer. The "reference share proportionate reduction" means a proportionate reduction in the number of reference shares which are the subject of the applicable reference share offer and attributable to one PHONES calculated in accordance with the following formula: R = X --------- N where: R = the fraction by which the number of reference shares of the class of reference shares subject to the reference share offer and attributable to one PHONES will be reduced. X = the aggregate number of reference shares of the class or series of reference shares subject to the reference share offer accepted in the reference share offer. N = the aggregate number of reference shares of the class or series of reference shares subject to the reference share offer outstanding immediately prior to the expiration of the reference share offer. If we elect to make a reference share offer adjustment, we will distribute as additional interest on each PHONES the average transaction consideration deemed to be received on the reference shares of the class or series subject to the reference share offer and attributable to each PHONES immediately prior to giving effect to the reference share proportionate reduction relating to that reference share offer (other than average transaction consideration that is publicly traded equity securities which will themselves become reference shares as a result of a reference share offer adjustment). If we elect to make a reference share offer adjustment, and during the pendency of the reference share offer another reference share offer is commenced in relation to the reference shares that are the subject of the then existing reference share offer, we can change our original election by electing to increase the early exchange ratio to 100% of the reference shares and agree to pay the other amounts described above during the pendency of the new reference share offer, or we can continue to elect to make a reference share offer adjustment. We will similarly be entitled to change our election for each further reference share offer made during the pendency of any reference share offer for the same class of reference shares. For the purposes of 30 these adjustments, a material change to the terms of an existing reference share offer will be deemed to be a new reference share offer. If we elect to increase the early exchange ratio to 100% of the reference shares in connection with a reference share offer, no reference share offer adjustment will be made, and we cannot change our election if any further reference share offer is made. We will give the trustee notice of our election in the event of any reference share offer. We will also prepare a press release and provide it to DTC for dissemination through the DTC broadcast facility. We will give this notice no later than 10 business days before the scheduled expiration of the reference share offer. Calculations in Respect of the PHONES We will be responsible for making all calculations called for under the PHONES. These calculations include, but are not limited to, determination of: o the contingent principal amount of the PHONES; o the current market value of the reference shares; o the exchange market value of the reference shares; o the final period distribution on the PHONES; o the fair market value of any property distributed on the reference shares; o the average transaction consideration in a reference share offer; o the composition of a reference share; and o the amount of accrued interest payable upon redemption or at maturity of the PHONES.prospectus supplement.

These conditions include: o that no event of default or event, which with notice or lapse of time would become an event of default with respect to cash dividendsthe debt securities of the series, will have occurred and be continuing on the reference shares,date of the deposit or insofar as an event of default described in clause (e) of the first paragraph under "-- Events of Default" is concerned, at any time during the period ending on the 181st day of the deposit; and such default continues for 30 days; o if wethat the defeasance or Alliant Energy Corporation defaultcovenant defeasance will not result in payment of principalthe breach or violation of, or premium, if any, onconstitute a default under, the PHONES when the same become due at maturity, upon redemption, by declaration or otherwise; o if we or Alliant Energy Corporation materially default in the performance or materially breach any of our respective covenants or obligations in the Indenture, any supplemental indenture or the PHONES and thisany other material default or breach continues for a period of 90 days after we or Alliant Energy Corporation receive written notice from the Trustee or the holders of at least 25% in aggregate principal amount of the outstanding PHONES; o if we or Alliant Energy Corporation default in the payment of the principal of any bond, debenture, note or other evidence of indebtedness, in each case for money borrowed, or in the payment of principal under any mortgage, indentureagreement or instrument under which there may be issuedResources is bound or byunder which there may be secured or evidenced any indebtedness for money borrowed, which default for payment of principal is in an aggregate principal amount exceeding $25,000,000 (or its equivalent in any other currency or currencies) when such indebtedness becomes due and payable (whether at maturity, upon redemption or acceleration or otherwise), if such default continues unremedied or unwaived for more than 30 business days and the time for payment of such amount has not been expressly extended; o our failure or the failure by Alliant Energy Corporation generally to pay our respective debts as they become due, or the admission in writing of our inabilityis bound. (Section 8.04). To exercise any such option, Resources or Alliant Energy, Corporation's inability to pay our respective debts generally, or the making of a general assignment for the benefit of our respective creditors, or the institution of any proceeding by or against Alliant Energy Corporation or us (other than any proceeding brought against us or Alliant Energy Corporation, as applicable, that is dismissed within 180 days from its commencement) seeking to adjudicate us or Alliant Energy Corporation, as the case may be, bankrupt or insolvent, or seeking liquidation, winding up, reorganization, arrangement, adjustment, protection, relief or composition (in each case, other than a solvent liquidation, winding up, reorganization, arrangement, adjustment, protection, relief or composition) of us or Alliant Energy Corporation, as the case may be, or our respective debts under any law relating to bankruptcy, insolvency, reorganization, moratorium or relief of debtors, or seeking the entry of an order for relief or appointment of an administrator, receiver, trustee, intervenor or other similar official for us or Alliant Energy Corporation, as the case may be, or for any substantial part of our property or the property of Alliant Energy Corporation, or the taking of any action by Alliant Energy Corporation or us to authorize any of the actions set forth in this clause; and 41 o a material default in the performance or material breach by Alliant Energy Corporation of any covenant or obligation of Alliant Energy Corporation contained in the guarantee, and the continuance of such material default or breach for a period of 90 days after which we or Alliant Energy Corporation receive written notice from the Trustee or the holders of at least 25% in aggregate principal amount of the PHONES. If an Event of Default with respect to the PHONES occurs and is continuing, either the Trustee or the holders of at least 25% in aggregate principal amount of the outstanding PHONES may declare the principal amount of the outstanding PHONES, and any interest accrued on the PHONES, including basic interest, additional interest and amounts relating to cash dividends on the reference shares, to be due and payable immediately by delivering a written notice to us and Alliant Energy Corporation (and to the Trustee if given by the holders). At any time after this declaration of acceleration has been made, but before a judgment or decree for payment of money has been obtained, the holders of a majority in principal amount of all of the PHONES, by notice to the trustee, may rescind this declaration and all its consequences if all Events of Default have been cured or waived (other than the non-payment of principal of the outstanding PHONES which has become due solely by reason of the declaration of acceleration), and such declaration of acceleration and its consequences will be automatically annulled and rescinded.

However, these limitations do not apply to a suit instituted by a holder of any PHONES for the enforcement of the payment of the principal of or premium, if any, or interest on the PHONES on or after the applicable due date specified in the PHONES. If the Trustee collects any money pursuant to an Event of Default, it will pay out the money in the following order: o first, to the Trustee for amounts to it as compensation for its services and any indemnities owed to it; o second, to holders of the PHONES in respect of which or for the benefit of which such money has been collected for amounts due and unpaid on the PHONES for principal and interest, 42 ratably, without preference or priority of any kind, according to the amounts due and payable on the PHONES for principal and interest, respectively; and o third, to the person or persons lawfully entitled thereto, or as a court of competent jurisdiction may direct. The Trustee may fix a record date (with respect to registered securities) and payment date for any such payment to holders of the PHONES. Any such record date will not be less than 10 days nor more than 60 days prior to the applicable payment date. Payment and Paying Agent We have appointed the Trustee to act as paying agent with respect to the PHONES. We may at any time designate additional paying agents or rescind the designation of any paying agents or approve a change in the office through which any paying agent acts, except that we will be required to maintain a paying agent in each place of payment for the PHONES. All moneys paid by usdeliver to the paying agenttrustee: o an opinion of counsel to the effect that the holders of the debt securities to be defeased will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such deposit, and will be subject to U.S. federal income tax on the paymentsame amounts, in the same manner and at the same times as would have been the case absent the deposit, which in the case of defeasance must be based on a change in law or a published ruling by the U.S. Internal Revenue Service, and the deposit will not result in Resources or Alliant Energy being deemed an "investment company" required to be registered under the Investment Company Act of 1940; and o an officer's certificate as to compliance with all conditions precedent provided for in the indenture relating to the satisfaction and discharge of the debt securities. (Section 8.04).

If the trustee is unable to apply any money or U.S. government securities deposited in trust to effect a defeasance or covenant defeasance by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such amounts.application, then any obligations from which Resources or Alliant Energy had been discharged or released will be revived and reinstated as though no such deposit of moneys in trust had occurred, until the time that the trustee is permitted so to apply all of the money or U.S. government securities deposited in trust. (Section 8.06). 17 Governing Law The Indentureindenture and the PHONES aredebt securities will be governed by, and construed in accordance with, the laws of the State of Wisconsin. 43(Section 10.09). 18 CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS General In this section, we summarize certainDESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS Alliant Energy may issue stock purchase contracts, including contracts that obligate holders to purchase from Alliant Energy, and Alliant Energy to sell to these holders, a specified number of shares of common stock at a future date or dates. The price per share of common stock may be fixed at the time the stock purchase contracts are issued or may be determined by reference to a specific formula set forth in the stock purchase contracts. The stock purchase contracts may be issued separately or as a part of stock purchase units. Stock purchase units consist of a stock purchase contract and either debt securities of Resources, debt securities of other Alliant Energy subsidiaries or debt obligations of third parties, including U.S. Treasury securities, securing the holders' obligations to purchase the common stock under the stock purchase contracts. The stock purchase contracts may require Alliant Energy and/or Resources to make periodic payments to the holders of some or all of the material United Statesstock purchase units or vice versa, and such payments may be unsecured or prefunded on some basis. The stock purchase contracts may require holders to secure their obligations under these stock purchase contracts in a specified manner. A prospectus supplement will describe the terms of any stock purchase contracts or stock purchase units being offered. The description in the prospectus supplement will not necessarily be complete, and you should read the stock purchase contracts and, if applicable, collateral or depositary arrangements, relating to the stock purchase contracts or stock purchase units. Material U.S. federal income tax consequences of purchasing, holdingconsiderations applicable to the stock purchase units and disposing of PHONES. Except where we state otherwise, this summary deals only with PHONES held as capital assets (as definedstock purchase contracts will be discussed in the Internal Revenue Coderelated prospectus supplement. 19 PLAN OF DISTRIBUTION Alliant Energy and Resources may sell the securities in one or more of 1986,the following ways from time to time: o to or through underwriters or dealers; o directly to a limited number of purchasers or to a single purchaser; o through agents; or o any combination of these. The applicable prospectus supplement will set forth the terms of the offering of securities, including the name or names of any underwriters, dealers or agents, the purchase price of the securities and the proceeds to Alliant Energy or Resources from the sale, any underwriting discounts or agency fees and other items constituting underwriters' or agents' compensation and any discounts or concessions allowed or reallowed or paid to dealers. If underwriters are utilized in the sale, the securities will be acquired by the underwriters for their own account pursuant to an underwriting agreement that Alliant Energy, Resources or both, as amended) bythe case may be, will execute with the underwriters at the time an agreement for such sale is reached. Such securities may be resold from time to time in one or more transactions, including negotiated transactions, at a U.S. Holder (as defined below) who purchases PHONES for cash at their originalfixed public offering price upon original issuance. We do not addressor prices, which may be changed, or at market or varying prices determined at the time of sale. The securities may be either offered to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. Generally, the obligations of the underwriters to purchase securities will be subject to conditions precedent and the underwriters will be obligated to purchase all of the tax consequences thatsecurities if any are purchased. Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be relevantchanged from time to a U.S. Holder. We also do not address anytime. If dealers are utilized in the sale of the tax consequences to holders that are Non-U.S. Holders (as defined below)securities, Alliant Energy or to holders that may be subject to special tax treatment such as financial institutions, real estate investment trusts, personal holding companies, tax-exempt organizations, regulated investment companies, insurance companies, S corporations, brokers and dealers inResources will sell the securities or currencies and certain U.S. expatriates. Further, we do not address: o the United States federal income tax consequences to shareholders in, or partners or beneficiaries of, an entity that is a holder of PHONES; o the United States federal estate, gift or alternative minimum tax consequences of the purchase, ownership or disposition of PHONES; o persons who hold PHONES in a straddle or as part of a hedging, conversion, constructive sale or other integrated transaction or whose functional currency is not the United States dollar; or o any state, local or foreign tax consequences of the purchase, ownership or disposition of PHONES. Accordingly, you should consult your own tax advisor regarding the tax consequences of purchasing, owning and disposing of PHONES in light of your own circumstances. A U.S. Holder is a beneficial owner of PHONES who or which is: o a citizen or individual resident of the United States, as defined in Section 7701(b) of the Internal Revenue Code; o a corporation or partnership, including any entity treated as a corporation or partnership for United States federal income tax purposes, created or organized in or under the laws of the United States, any state thereof or the District of Columbia unless, in the case of a partnership, Treasury regulations are enacted that provide otherwise; o an estate if its income is subject to United States federal income taxation regardless of its source; or o a trust if (1) a United States court can exercise primary supervision over its administration and (2) one or more United States persons have the authority to control all of its substantial decisions. 44 Notwithstanding the preceding sentence, certain trusts in existence on August 20, 1996, and treated as a U.S. Holder prior to such date, may also be treated as U.S. Holders. A Non-U.S. Holder is a PHONES holder other than a U.S. Holder. Prospective investors that are Non-U.S. Holders are urged to consult their own tax advisors regarding the United States federal income tax consequences of an investment in PHONES, including potential application of United States withholding taxes. This summary is based on the Internal Revenue Code, Treasury regulations (proposed and final) issued under the Internal Revenue Code, and administrative and judicial interpretations thereof, all as they currently exist as of the date of this private placement memorandum and any of which may change at any time, possibly on a retroactive basis. Any such changes may affect this summary. No statutory, administrative or judicial authority directly addresses the treatment of PHONES or instruments similar to PHONES for United States federal income tax purposes. No rulings have been sought or are expected to be sought from the IRS with respect to any of the United States federal income tax consequences discussed below, and no assurance can be given that the IRS will not take contrary positions. As a result, no assurance can be given that the IRS will agree with the tax consequences described herein. Prospective investors are urged to consult their own tax advisors with respect to the tax consequences to them ofdealers, as principals. The dealers may then resell the purchase, ownership and disposition of phones in light of their own particular circumstances, including the tax consequences under state, local, foreign and other tax laws and the possible effects of changes in United States federal or other tax laws. Accrual of interest on the PHONES For United States federal income tax purposes, the PHONES will be treated as debt instruments that are subject to the special regulations governing contingent payment debt instruments, which we refer to as the CPDI regulations. Pursuant to these regulations, U.S. Holders of the PHONES will be required to accrue interest income on the PHONES, in the amounts described below, regardless of whether the U.S. Holder uses the cash or accrual method of tax accounting. Accordingly, U.S. Holders will be required to include interest in taxable income in each year in excess of any interest payments actually received in that year. The CPDI regulations provide that a U.S. Holder must accrue an amount of ordinary interest income, as original issue discount, for each accrual period prior to and including the maturity date of the PHONES that equals: o the product of (i) the PHONES adjusted issue price (as defined below) as of the beginning of the accrual period; and (ii) the PHONES comparable yield to maturity (as defined below) adjusted for the length of the accrual period; o divided by the number of days in the accrual period; and o multiplied by the number of days during the accrual period that the U.S. Holder held the PHONES. A PHONES issue price is the first pricesecurities to the public at which a substantial amount of the PHONES is sold, excluding salesvarying prices to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers. A PHONES adjusted issue price is the PHONES issue price increased by any interest income previously accrued,be determined without regard to any adjustments to interest 45 accruals described below and decreased by the amount of any projected payments, as defined below, with respect to the PHONES. The term "comparable yield" means the annual yield we would pay, as of the issue date of the PHONES, on a fixed-rate debt security with no contingent payments, but with terms and conditions otherwise comparable to those of the PHONES. We have determined that the PHONES comparable yield is 9.49% per annum, compounded quarterly. The CPDI regulations require that we provide to U.S. Holders, solely for United States federal income tax purposes, a schedule of the projected amounts of payments, which we refer to as projected payments, on the PHONES. This schedule must produce the comparable yield. Based on our determination of the comparable yield, the PHONES schedule of projected payments, assuming a principal amount of $67.75 or with respect to each integral multiple thereof, consists of: o payments of stated interest equal to $1.2280 on quarterly interest payment dates through February 15, 2003; plus o payments of stated interest equal to $.4234 on all other quarterly interest payment dates thereafter; plus o a payment of a projected amountdealers at the maturity datetime of the PHONES, excluding the stated quarterly interest on the PHONES payable on such date, equal to $705.73. For United States federal income tax purposes, a U.S. Holder must use the comparable yield and the schedule of projected payments in determining its interest accruals, and the adjustments described below, in respect of the PHONES, unless such U.S. Holder timely discloses and justifies the use of other estimates to the Internal Revenue Service. The comparable yield and the schedule of projected payments are not provided for any purpose other than the determination of U.S. Holders' interest accruals and adjustments thereof in respect of the PHONES for United States federal income tax purposes and do not constitute a projection or representation regarding the actual amounts payable on the PHONES. Amounts treated as interest under the CPDI regulations are treated as original issue discount for all purposes of the Internal Revenue Code. Adjustments to interest accruals on the PHONES If, during any taxable year, a U.S. Holder were to receive actual payments with respect to the PHONES for that taxable year, including, in the case of the taxable year which includes the maturity date of the PHONES, the amount of cash received at maturity, that in the aggregate exceed the total amount of projected payments for that taxable year, the U.S. Holder will incur a "net positive adjustment" under the CPDI regulations equal to the amount of such excess. The U.S. Holder will treat this adjustment as additional interest income for the taxable year. For this purpose, the payments in a taxable year include the fair market value of property received in that year. If a U.S. Holder were to receive in a taxable year actual payments with respect to the PHONES for that taxable year that in the aggregate were less than the amount of projected payments for that taxable year, the U.S. Holder will incur a "net negative adjustment" under the CPDI regulations equal to the amount of such deficit. This adjustment will (a) reduce the U.S. Holder's interest income on the PHONES for that taxable 46 year, and (b) to the extent of any excess after the application of (a), give rise to an ordinary loss to the extent of the U.S. Holder's interest income on the PHONES during prior taxable years, reduced to the extent such interest was offset by prior net negative adjustments. Sale, exchange or redemption of the PHONES Generally, the sale, exchange or redemption of the PHONES, including exchanges at the U.S. Holder's option and redemptions by us, prior to their maturity date will result in taxable gain or loss to the U.S. Holder equal to the difference between (a) the amount of cash plus the fair market value of any other property received by the U.S. Holder, and (b) the U.S. Holder's adjusted tax basis in the PHONES. A U.S. Holder's adjusted tax basis in the PHONES equals the holder's original basis in the PHONES: o increased by the interest income previously included by the U.S. Holder with respect to the PHONES, determined without regard to any adjustments to interest accruals described above; and o decreased by the amount of all prior projected payments with respect to the PHONES. Any gain upon a sale or exchange of the PHONES will be ordinary interest income. Any loss will be ordinary loss to the extent of the interest previously included in income by the U.S. Holder with respect to the PHONES and, thereafter, capital loss. The distinction between capital loss and ordinary loss is potentially significant in several respects. For example, limitations apply to a U.S. Holder's ability to offset capital losses against ordinary income. Backup withholding tax and information reporting Payments of principal, premium, if any, and interest (including original issue discount) on, and the proceeds of disposition of, the PHONES may be subject to information reporting and United States federal backup withholding tax at the rate of 31% if the U.S. Holder thereof fails to supply an accurate taxpayer identification number or otherwise fails to comply with applicable United States information reporting or certification requirements. Any amounts so withheld will be allowed as a credit against such U.S. Holder's United States federal income tax liability. 47 SELLING SECURITY HOLDERS The following table sets forth the names of the selling security holders and the number of PHONES owned by each of them.
