CERTAIN TERMS OF THE DEBENTURES

The following description of the particular terms of the Debentures supplements, and to the extent inconsistent therewith replaces, the description of the general terms and provisions of the Debentures set forth in the accompanying Prospectus under "Description of the Debentures," to which description reference is hereby made.

General

The Debentures will be unsecured general obligations of the Company and will be issued as a separate series of securities under the Indenture, dated as of June 20, 1997 (the "Unsecured Debt Indenture"), between the Company and Firstar Trust Company, as Trustee. At March 31, 1997, the Company had no Securities (as defined in the accompanying Prospectus) outstanding under the Indenture but had $371,874,000 of secured debt outstanding. The Unsecured Debt Indenture does not limit the Company's ability to issue additional First Mortgage Bonds or to enter into sale and leaseback transactions. See "Description of the New Bonds" in the accompanying Prospectus.

Maturity and Interest

The Debentures will be limited to $105,000,000 aggregate principal amount and will mature on , 2007. Each Debenture will bear interest from , 1997 or from the most recent interest payment date to which interest has been paid, at the rate per annum specified on the cover page hereof, payable semi-annually on and , commencing , 1997, to the person in whose name such Debenture is registered at the close of business on the preceding and , respectively.

No Redemption Prior to Maturity

The Debentures will not be redeemable prior to maturity.

Other Terms

The covenant described in the accompanying Prospectus under "Description of the Debentures--Certain Covenants--Limitations on Liens" will apply to the Debentures. Future series of Securities issued under the Indenture may or may not have different covenants.

The Debentures will be subject to defeasance under the conditions described in the accompanying Prospectus.

Book-Entry Procedures

The Debentures will be represented by one or more global securities registered in the name of DTC or its nominee. Book-Entry Interests in such global securities will be shown on, and transfers thereof will be effected only through, records maintained by DTC or its nominee for such global securities and on the records of DTC Participants (as defined in the accompanying Prospectus). Except as described below and in the accompanying Prospectus, Debentures in definitive form will not be issued and owners of Book-Entry Interests will not be considered the holders thereof.

The laws of some states require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limits and such laws may impair the ability to transfer beneficial interests in the global securities.

In the event that the book-entry system is discontinued, or DTC is at any time unwilling or unable to continue as depositary, and a successor depositary is not appointed by the Company within 90 days, the Company will issue individual Debentures in certificated form to owners of Book- Entry Interests in exchange for the Debentures held by DTC or its nominee, as the case may be.

Settlement for the Debentures will be made by the Underwriters in immediately available funds. All payments of principal and interest on global securities will be made by the Company in immediately available funds.

See "Book-Entry Only System" in the accompanying Prospectus.

Following the merger, the Company will be a subsidiary of Interstate Energy. The merger will not affect the separate corporate existence of the Company nor will it impair the lien of the Company's Indenture of Mortgage or Deed of Trust, dated August 1, 1941, securing its First Mortgage Bonds or the rights and powers of the trustees or debtholders thereunder.

USE OF PROCEEDS

The Company intends to use the net proceeds from the sale of the Debt Securities offered hereby to repay indebtedness, including the retirement, redemption or refinancing of existing series of the Company's First Mortgage Bonds. Unless otherwise specified in the Prospectus Supplement, any proceeds not used for the foregoing purpose will be added to the general funds of the Company and used for general corporate purposes.

RATIOS OF EARNINGS TO FIXED CHARGES

Set forth below are the ratios of earnings to fixed charges (unaudited) for the Company for the twelve months ended March 31, 1997 and for the last five years:

Twelve Months
                                Year Ended December 31,
    Ended
  March 31,
     1997             1996          1995     1994       1993      1992

     4.35             4.81          4.23     4.29       3.74      3.47

For the purpose of computing the ratios of earnings to fixed charges, earnings have been calculated by adding to income before interest expense, Federal and state income taxes and the estimated interest component of rentals. Fixed charges represent interest expense, amortization of debt discount, premium and expense and the estimated interest component of rentals.

DESCRIPTION OF THE NEW BONDS

The term "Company" as used under this heading does not include its subsidiaries. The properties of the Company's subsidiaries, which are not material in the aggregate, are not subject to the lien of the First Mortgage Indenture hereinafter referred to and do not constitute bondable property under such First Mortgage Indenture.

General

The New Bonds will be issued by the Company under the Indenture of Mortgage or Deed of Trust, dated August 1, 1941, executed by the Company to First Wisconsin Trust Company (now known as Firstar Trust Company) and George B. Luhman (Gene E. Ploeger being now the individual trustee under said Indenture), as Trustees (collectively, the "First Mortgage Trustee"), as amended by the several indentures supplemental thereto heretofore executed and as to be further amended and supplemented by one or more supplemental indentures creating the series in which the New Bonds are to be issued (said Indenture, as so amended, being herein called the "First Mortgage Indenture").

The following statements, unless the context otherwise indicates, are brief summaries of the substance or general effect of certain provisions of the First Mortgage Indenture, which is filed with the Commission as an exhibit to the Registration Statement for the Debt Securities. Such statements are not complete and are qualified in their entirety by reference to the First Mortgage Indenture. The specific references below are to provisions of the First Mortgage Indenture.

Terms

Reference is made to the Prospectus Supplement relating to any series of the New Bonds for the following terms thereof, among others:
(a) the title or designation of the New Bonds; (b) the date of the New Bonds; (c) the date or dates on which the New Bonds may mature; (d) the rate or rates (which may be fixed or variable) per annum at which the New Bonds will bear interest, if any, and the date from which such interest, if any, will accrue; (e) the times at which any such interest will be payable; (f) any provisions governing redemption, medium of payment and sinking funds or analogous funds; and (g) any limit on the aggregate principal amount of the New Bonds. (Article I, Section 1)

Unless otherwise indicated in the Prospectus Supplement relating thereto, (a) the New Bonds are to be issuable only in definitive fully registered form without coupons in denominations of $1,000 and integral multiples of $1,000; (b) the transfer and exchange of the New Bonds will be made without charge, except for any stamp tax or other governmental charge; and (c) the New Bonds will be transferable and exchangeable in Milwaukee, Wisconsin or New York, New York.

The New Bonds of a series may be issued in whole or in part in the form of one or more global bonds that will be deposited with, or on behalf of, a depositary identified in the Prospectus Supplement relating to the series. The specific terms of the depositary arrangement with respect to any global bonds of a series will be described in the Prospectus Supplement relating to the series. See "Book- Entry Only System."

Maintenance and Repair

For all series of First Mortgage Bonds issued prior to the bonds of Series W (the "Series W Bonds"), the First Mortgage Indenture provides that during each year such previously issued bonds are outstanding the Company will expend, and certify to the First Mortgage Trustee, amounts aggregating not less than 15% of the gross operating revenues (less the cost of power, gas and water purchased for exchange or resale) derived during such year from the operation of the physical properties on which the First Mortgage Indenture is a lien, for (a) maintenance and repair of such properties, (b) bondable property on which the First Mortgage Indenture is a first mortgage lien, and/or (c) retirement of bonds; or will deposit with the First Mortgage Trustee cash to the extent of any deficiency in such amount, after applying any available credit for unused excess expenditures made for those purposes in any prior year. Such cash may be withdrawn to the extent of 100% of net expenditures or excess gross expenditures for bondable property, or applied to the redemption of bonds if then redeemable or to the purchase of bonds. (Article VII, Section 1) The supplemental indenture, dated March 1, 1992, creating the Series W Bonds amended the First Mortgage Indenture to delete the covenant requiring the annual expenditure of at least 15% of the Company's gross operating revenues as described above for all subsequently issued bonds beginning with the Series W Bonds (including the New Bonds) and, as a result, the Company will be required to comply with such covenant for so long as bonds issued prior to the Series W Bonds remain outstanding or until the holders of the requisite principal amount of the previously issued bonds consent to such amendment.

The First Mortgage Indenture also provides that (a) the Company shall maintain the mortgaged properties in good repair and working order;
(b) the First Mortgage Trustee may, and if requested by holders of a majority in principal amount of all outstanding bonds and furnished with the necessary funds therefor shall, cause such properties to be inspected by an independent engineer (not more often than at five-year intervals) to determine whether they have been so maintained and whether any property, not retired on the books, should be classified as retired for the purpose (among others) of computing "net expenditures" for bondable property; and
(c) the Company shall make good any deficiency in maintenance disclosed by such engineer's report as rendered or as modified by arbitration.
(Article III, Sections 7 and 8)

Security

The New Bonds will be secured by the lien of the First Mortgage Indenture and will rank pari passu with all bonds at any time outstanding under the First Mortgage Indenture, except as to differences between series permitted by the First Mortgage Indenture and not affecting the rank of the lien. The First Mortgage Indenture constitutes a first mortgage lien, subject only to permitted encumbrances and liens, as defined, on all or substantially all the permanent fixed properties (other than excepted property) now owned by the Company. (Granting Clause and Excepted Property Clause) The First Mortgage Indenture contains provisions subjecting "after-acquired property" (other than excepted property) to the lien thereof. (Granting Clause) However, the priority of the lien on "after-acquired property" would date from the filing or recording of a subsequent instrument confirming of record that such property is subject to the lien. In addition, such provisions might not be effective as to property acquired, and as to certain rents, issues and products accruing, subsequent to the filing of any case with respect to the Company under the Federal Bankruptcy Code. The First Mortgage Indenture excepts from the lien thereof all cash, securities, accounts and bills receivable, choses in action and certain judgments not deposited or pledged with the First Mortgage Trustee, all tangible personal property held for sale, rental or consumption in the ordinary course of business, the last day of each term under any lease of property, all gas, oil and other minerals upon or under any real estate subject thereto, and certain real estate described therein.

The First Mortgage Indenture does not prevent a merger or consolidation of the Company, a sale by the Company of all or substantially all of its assets, a recapitalization of the Company or other comparable transaction as long as the lien of the First Mortgage Indenture is preserved on the property then subject to such lien. The First Mortgage Indenture also does not restrict the amount of unsecured debt (including, without limitation, Debentures) the Company can incur. Other than the security afforded by the lien of the First Mortgage Indenture and the restrictions on the issuance of additional bonds described below, there are no covenants or provisions of the First Mortgage Indenture which provide protection to bondholders in the event of a highly leveraged transaction involving the Company.

Release and Substitution of Property

The Company may sell or otherwise dispose of property subject to the lien of the First Mortgage Indenture, and the First Mortgage Trustee shall release such property from the lien of the First Mortgage Indenture, upon receipt by the First Mortgage Trustee, or the trustee under any mortgage constituting a prior lien on such property, of any money and/or purchase money obligations received by the Company in consideration for such property in an amount not less than the fair value of such property.


(Article VIII, Section 2)

Issuance of Additional Bonds

The First Mortgage Indenture does not fix an overall limitation on the total principal amount of bonds that may be issued or outstanding thereunder, but limits the principal amount of bonds of each presently outstanding series that may be so outstanding.

Additional bonds currently may be issued from time to time under the First Mortgage Indenture, subject to the terms thereof, in a principal amount not to exceed: (a) 60% of "net expenditures" made for bondable property (as defined) constructed or acquired by the Company on or after August 1, 1941, and on which the First Mortgage Indenture is a first mortgage lien, subject only to permitted encumbrances and liens and prepaid liens, as defined; (b) the principal amount of bonds, previously authenticated under the First Mortgage Indenture, which have been retired or for the retirement of which the First Mortgage Trustee holds the necessary funds, other than certain bonds retired through the operation of the debt retirement or the maintenance and repair provisions of the First Mortgage Indenture; and/or (c) the amount of cash deposited with the First Mortgage Trustee for that purpose, which cash may be applied to the retirement of bonds or may be withdrawn in lieu of the authentication of an equal principal amount of bonds under the First Mortgage Indenture provisions referred to in clauses (a) and (b). (Article II, Sections 2, 3 and 4) Bondable property means, in general, any electric, gas or water utility plant, property or equipment constructed or acquired by the Company on or after August 1, 1941, and used or useful in such utility business. "Net expenditures" for bondable property are determined as provided in the First Mortgage Indenture. In connection with the issuance of the Series W Bonds, the supplemental indenture creating such bonds amended the First Mortgage Indenture to allow for the issuance of additional bonds based on 70% of net expenditures made for bondable property as compared with the current 60%. Notwithstanding the amendment effected by the supplemental indenture creating the Series W Bonds, the 60% limitation will continue to govern the issuance of additional bonds for so long as bonds issued prior to the Series W Bonds remain outstanding or until the holders of the requisite principal amount of the previously issued bonds consent to such amendment.

No additional bonds may be authenticated under the First Mortgage Indenture provisions referred to in clauses (a) and (c) above, and no bonds bearing a higher rate of interest than the bonds for the retirement of which they are to be issued may be authenticated under the First Mortgage Indenture provisions referred to in clause (b) above more than five years before the maturity of the bonds to be retired, unless, in each case, the net earnings of the Company for 12 consecutive months ending within 90 days next preceding such authentication were at least equal to twice the interest for one year on (i) all the bonds to be outstanding under the First Mortgage Indenture immediately after such authentication, other than those for the retirement of which the necessary funds are held by the First Mortgage Trustee, and (ii) all other indebtedness secured by an equal or prior lien on any part of the Company's property. "Net earnings" for any period means the total gross earnings and income of the Company, less all of its operating expenses (including depreciation and taxes other than taxes measured by income) for the period, computed as provided in the First Mortgage Indenture. (Article II, Section 5)

Modification of First Mortgage Indenture

The First Mortgage Indenture may not be amended without the consent of bondholders, except for certain limited purposes therein provided. Such purposes include, among others, (a) any change of the provisions of the First Mortgage Indenture provided that such change be made effective only with respect to bonds authenticated after the execution of the supplemental indenture effecting such change and only if it would not adversely affect the bonds then outstanding under the First Mortgage Indenture and (b) any other change not inconsistent with the terms and which would not impair the security of the First Mortgage Indenture.


(Article XVI, Section 1)

By supplemental indenture dated May 15, 1978, the First Mortgage Indenture was amended, effective upon the retirement or redemption, or with the consent of the holders, of all outstanding bonds of all series issued prior to the bonds of Series R, to provide that, with the consent of the holders of not less than 66-2/3% in principal amount of bonds then outstanding, the First Mortgage Indenture may be amended in any respect, except that without the consent of the holder of each outstanding bond affected thereby no such amendment shall, among other things, (a) extend the time for, reduce or otherwise affect the terms of payment of the principal of or interest or premium on any bond, (b) permit the creation of any lien ranking prior to or on a parity with the lien of the First Mortgage Indenture, other than permitted encumbrances and liens or prepaid liens, (c) reduce the percentage in principal amount of bonds the consent of the holders of which is required for any such amendment, (d) impair the right of any bondholder to institute suit for the enforcement of any payment in respect of such bondholder's bonds or (e) deprive any non-consenting bondholder of a lien upon the mortgaged property for the security of such bondholder's bonds. (Article XVIII)

Other First Mortgage Indenture Provisions

The First Mortgage Indenture provides in effect, with respect to
(a) bondholders' rights to direct the First Mortgage Trustee to take action thereunder, (b) defaults thereunder and notice to bondholders with respect thereto and (c) compliance with First Mortgage Indenture provisions, as follows:

(1) Holders of a majority in principal amount of the bonds secured by the First Mortgage Indenture have the right to direct the time, method and place of conducting proceedings for remedies available to, or exercising any trust or power of, the First Mortgage Trustee. However, the First Mortgage Trustee may decline to follow such directions under certain circumstances specified in the First Mortgage Indenture, and is not required to exercise powers of entry or sale under the First Mortgage Indenture. (Article X, Section 12)

(2) A "default" or an "event of default" means: (a) failure to pay the principal of any bond secured by the First Mortgage Indenture when due at maturity or otherwise; (b) failure to pay bond interest within 60 days after its due date; (c) failure to pay the principal of, or interest on, any prior lien bond, continued beyond the default period (if any) specified in the lien securing such bond; (d) failure of the Company for 90 days after written demand to comply with any other covenant or condition in the First Mortgage Indenture or in any such bond or any prior lien or bond secured thereby; or (e) the occurrence of certain events of bankruptcy, insolvency, assignment or receivership in respect to the Company. (Article X, Section 1) The First Mortgage Trustee may withhold giving notice to bondholders of defaults (other than any default in payment of interest, principal or sinking or purchase fund installment in respect of any bond secured by the First Mortgage Indenture) if it determines in good faith that such withholding is in the interests of the bondholders. (Article XV, Section 2) Upon default, the First Mortgage Trustee may, and upon written notice from the holders of a majority in principal amount of bonds then outstanding shall, declare the principal of all bonds secured by the First Mortgage Indenture to be immediately due and payable. (Article X, Section 4) Upon certain terms and conditions, the declaration of acceleration may be rescinded and waived.

(3) The Company shall furnish to the First Mortgage Trustee certificates of officers and engineers and, in certain cases, of accountants in connection with the authentication of bonds, withdrawal of money, release of property and other matters, and opinions of counsel as to the lien of the First Mortgage Indenture and other matters. No periodic evidence is required to be filed with the First Mortgage Trustee as to the absence of defaults; and no such evidence is required to be filed as to compliance with the terms of the First Mortgage Indenture, except for the filing annually of certificates with respect to the satisfaction of the maintenance and renewal and the debt retirement provisions of the First Mortgage Indenture and of an opinion of counsel with respect to the lien of the First Mortgage Indenture.

Relationships with the First Mortgage Trustee

The Company maintains general checking accounts with several banks which are affiliates of the First Mortgage Trustee. The Company has $10 million in lines of credit with such banks, which are part of $70 million in lines of credit maintained with various banks. In addition, the Company and its parent, WPLH, each maintain short-term borrowing agreements with the First Mortgage Trustee pursuant to which the Company and WPLH may borrow up to $50 million and $50 million, respectively. Judith D. Pyle, a Director of the Company, is a Director of the First Mortgage Trustee's parent corporation, Firstar Corporation.

DESCRIPTION OF THE DEBENTURES

The Debentures will be issued in one or more series under the Indenture, dated as of June 20, 1997 (the "Unsecured Debt Indenture"), between the Company and Firstar Trust Company, as Trustee (the "Unsecured Debt Trustee"), which is filed as an exhibit to the Registration Statement for the Debt Securities. The following summaries of certain provisions of the Unsecured Debt Indenture and the Debentures do not purport to be complete and are subject to, and qualified in their entirety by reference to, all of the provisions of the Unsecured Debt Indenture and any Officers' Certificates or supplemental indentures relating thereto, including the definitions therein of certain terms. Whenever particular Sections or defined terms of the Unsecured Debt Indenture are referred to herein or in a Prospectus Supplement, such Sections or defined terms are incorporated by reference herein or therein, as the case may be.

The term "Securities," as used under this heading, refers to all Securities issued under the Unsecured Debt Indenture and includes the Debentures.

General

The Unsecured Debt Indenture does not limit the amount of Securities that can be issued thereunder and provides that the Securities may be issued from time to time in one or more series pursuant to the terms of one or more Officers' Certificates or supplemental indentures creating such series. As of the date of this Prospectus, there were no Securities outstanding under the Unsecured Debt Indenture. The Debentures will be unsecured and will rank on a parity with all other unsecured and unsubordinated debt of the Company. Although the Unsecured Debt Indenture provides for the possible issuance of Securities in other forms or currencies, the only Securities covered by this Prospectus will be Securities denominated in U.S. dollars in registered form without coupons.

Substantially all of the permanent fixed properties of the Company are subject to the lien of the First Mortgage Indenture under which the Company's First Mortgage Bonds are outstanding. See "Description of the New Bonds."

Terms

Reference is made to the Prospectus Supplement relating to any series of the Debentures for the following terms thereof, among others:
(a) the title or designation, aggregate principal amount, currency or composite currency and denominations of the Debentures; (b) the price at which the Debentures will be issued and, if an index formula or other method is used, the method for determining amounts of principal or interest; (c) the maturity date and other dates, if any, on which principal will be payable; (d) the rate or rates (which may be fixed or variable) per annum at which the Debentures will bear interest, if any;
(e) the date or dates from which interest will accrue and on which interest will be payable, and the record dates for the payment of interest; (f) the manner of paying principal and interest; (g) the place or places where principal and interest will be payable; (h) the terms of any mandatory or optional redemption by the Company; (i) the terms of any redemption at the option of Holders; (j) whether the Debentures are to be issuable as registered Securities, bearer Securities, or both, and whether and upon what terms any registered Securities may be exchanged for bearer Securities and vice versa; (k) whether the Debentures are to be represented in whole or in part by a Security in global form and, if so, the terms thereof and the identity of the depositary for any global Security; (l) any tax indemnity provisions; (m) if the Debentures provide that payments of principal or interest may be made in a currency other than that in which Debentures are denominated, the manner for determining such payments; (n) the portion of principal payable upon acceleration of a Discounted Security (as defined below); (o) whether and upon what terms Debentures may be defeased; (p) whether the covenant referred to below under "Certain Covenants--Limitations on Liens" applies, and any events of default or restrictive covenants in addition to or in lieu of those set forth in the Unsecured Debt Indenture; (q) provisions for electronic issuance of Debentures or for Debentures in uncertificated form; and (r) any additional provisions or other special terms not inconsistent with the provisions of the Unsecured Debt Indenture, including any terms that may be required or advisable under United States or other applicable laws or regulations, or advisable in connection with the marketing of the Debentures. (Section 2.01)

The Securities of a series may be issued in whole or in part in the form of one or more global Securities that will be deposited with, or on behalf of, a depositary identified in the Prospectus Supplement relating to the series. Global Securities may be issued in registered, bearer or uncertificated form and in either temporary or permanent form. Unless and until it is exchanged in whole or in part for Securities in definitive form, a global Security may not be transferred except as a whole by the depositary to a nominee or a successor depositary. (Section 2.12) The specific terms of the depositary arrangement with respect to any Securities of a series will be described in the Prospectus Supplement relating to the series. See "Book-Entry Only System."

Securities of any series may be issued as registered Securities, bearer Securities or uncertificated Securities, as specified in the terms of the series. (Section 2.01) Unless otherwise indicated in the Prospectus Supplement, registered Securities will be issued in denominations of $1,000 and whole multiples thereof and bearer Securities will be issued in denominations of $5,000 and whole multiples thereof. One or more global Securities will be issued in a denomination or aggregate denominations equal to the aggregate principal amount of outstanding Securities of the series to be represented by such global Security or Securities. (Section 2.12)

In connection with its original issuance, no bearer Security will be offered, sold, resold, or mailed or otherwise delivered to any location in the United States and a bearer Security in definitive form may be delivered in connection with its original issuance only if the person entitled to receive the bearer Security furnishes certification as described in United States Treasury regulation section 1.163-5(c)(2)(i)(D)(3). (Section 2.04)

For purposes of this Prospectus, unless otherwise indicated, "United States" means the United States of America (including the States thereof and the District of Columbia), its territories and possessions and all other areas subject to its jurisdiction. "United States person" means a citizen or resident of the United States, any corporation, partnership or other entity created or organized in or under the laws of the United States or a political subdivision thereof or any estate or trust the income of which is subject to United States Federal income taxation regardless of its source. Any special United States Federal income tax considerations applicable to bearer Securities will be described in the Prospectus Supplement relating thereto.

To the extent set forth in the Prospectus Supplement, except in special circumstances set forth in the Unsecured Debt Indenture, principal and interest on bearer Securities will be payable only upon surrender of bearer Securities and coupons at a paying agency of the Company located outside of the United States. During any period thereafter for which it is necessary in order to conform to United States tax law or regulations, the Company will maintain a paying agent outside the United States to which the bearer Securities and coupons may be presented for payment and will provide the necessary funds therefor to the paying agent upon reasonable notice. (Section 2.04)

Registration of transfer of registered Securities may be requested upon surrender thereof at any agency of the Company maintained for that purpose and upon fulfillment of all other requirements of the agent. (Sections 2.03 and 2.07) Bearer Securities and the coupons related thereto will be transferable by delivery.

Securities may be issued under the Unsecured Debt Indenture as Discounted Securities to be offered and sold at a substantial discount from the principal amount thereof. Special United States Federal income tax and other considerations applicable thereto will be described in the Prospectus Supplement relating to such Discounted Securities. "Discounted Security" means a Security where the amount of principal due upon acceleration is less than the stated principal amount of such Security.

Certain Covenants

The Debentures will not be secured by any properties or assets and will represent unsecured debt of the Company. The Unsecured Debt Indenture does not limit the amount of unsecured debt that the Company can incur. As indicated under "General" above, substantially all of the permanent fixed properties of the Company are subject to the lien of the First Mortgage Indenture securing the Company's First Mortgage Bonds.

As discussed below, the Unsecured Debt Indenture includes certain limitations on the Company's ability to create liens. Such limitations will apply if the Officers' Certificate or supplemental indenture establishing the terms of a series so provides. If applicable, the limitations are subject to a number of qualifications and exceptions. The Unsecured Debt Indenture does not limit the Company's ability to issue additional First Mortgage Bonds or to enter into sale and leaseback transactions.

The covenant described below will apply if so indicated in a Prospectus Supplement. Any obligations under the Unsecured Debt Indenture are subject to termination upon defeasance. See "Legal Defeasance and Covenant Defeasance" below. Also, unless otherwise indicated in a Prospectus Supplement, the Unsecured Debt Indenture does not afford holders of the Securities protection in the event of a highly leveraged or other transaction involving the Company that may adversely affect holders of the Securities.

Limitations on Liens. The Unsecured Debt Indenture provides that, so long as there remain outstanding any Securities of any series to which this limitation applies, and subject to termination as referred to above, the Company will not, and will not permit any Subsidiary to, create or suffer to be created or to exist any mortgage, pledge, security interest, or other lien (collectively, "Lien") on any of its properties or assets now owned or hereafter acquired to secure any indebtedness, without making effective provision whereby the Securities of such series shall be equally and ratably secured. This restriction does not apply to or prevent the creation or existence of (a) the First Mortgage Indenture securing the Company's First Mortgage Bonds or any indenture supplemental thereto subjecting any property to the Lien thereof or confirming the Lien thereof upon any property, whether owned before or acquired after the date of the Unsecured Debt Indenture; (b) Liens on property existing at the time of acquisition or construction of such property (or created within one year after completion of such acquisition or construction), whether by purchase, merger, construction or otherwise (or on the property of a Subsidiary at the date it became a Subsidiary), or to secure the payment of all or any part of the purchase price or construction cost thereof, including the extension of any such Liens to repairs, renewals, replacements, substitutions, betterments, additions, extensions and improvements then or thereafter made on the property subject thereto; (c) any extensions, renewals or replacements (or successive extensions, renewals or replacements), in whole or in part, of Liens (including, without limitation, the First Mortgage Indenture) permitted by the foregoing clauses (a) and (b); (d) the pledge of any bonds or other securities at any time issued under any of the Liens permitted by clauses
(a), (b) or (c) above; or (e) Permitted Encumbrances. (Section 4.07)

"Permitted Encumbrances" include, among other items, (a) the pledge or assignment in the ordinary course of business of electricity, gas (either natural or artificial) or steam, accounts receivable or customers' installment paper, (b) Liens affixing to property of the Company or a Subsidiary at the time a Person consolidates with or merges into, or transfers all or substantially all of its assets to, the Company or a Subsidiary, provided that in the opinion of the Board of Directors of the Company or Company management (evidenced by a certified Board resolution or an Officers' Certificate delivered to the Unsecured Debt Trustee) the property acquired pursuant to the consolidation, merger or asset transfer is adequate security for the Lien; and (c) Liens or encumbrances not otherwise permitted if, at the incurrence of and after giving effect thereto, the aggregate of all obligations of the Company and its Subsidiaries secured thereby does not exceed 10% of Tangible Net Worth. "Tangible Net Worth" means (i) common stockholders' equity appearing on the most recent balance sheet of the Company (or consolidated balance sheet of the Company and its Subsidiaries if the Company then has one or more consolidated Subsidiaries) prepared in accordance with generally accepted accounting principles less (ii) intangible assets (excluding intangible assets recoverable through rates as prescribed by applicable regulatory authorities). (Section 4.06)

Further, this restriction will not apply to or prevent the creation or existence of leases made, or existing on property acquired, in the ordinary course of business. (Section 4.07)

Other Covenants. Any other restrictive covenants which may apply to a particular series of Securities will be described in the Prospectus Supplement relating thereto.

Successor Obligor

The Unsecured Debt Indenture provides that, unless otherwise specified in the Officers' Certificate or supplemental indenture establishing a series of Securities, the Company will not consolidate with or merge into, or transfer all or substantially all of its assets to, any Person, unless (a) the Person is organized under the laws of the United States or a State thereof; (b) the Person assumes by supplemental indenture all the obligations of the Company under the Unsecured Debt Indenture, the Securities and any coupons; and (c) immediately after the transaction no Default (as defined) exists. The successor will be substituted for the Company, and thereafter all obligations of the Company under the Unsecured Debt Indenture, the Securities and any coupons shall terminate. (Section 5.01)

Exchange of Securities

Registered Securities may be exchanged for an equal aggregate principal amount of registered Securities of the same series and date of maturity in such authorized denominations as may be requested upon surrender of the registered Securities at an agency of the Company maintained for such purpose and upon fulfillment of all other requirements of the agent. (Section 2.07)

To the extent permitted by the terms of a series of Securities authorized to be issued in registered form and bearer form, bearer Securities may be exchanged for an equal aggregate principal amount of registered or bearer Securities of the same series and date of maturity in such authorized denominations as may be requested upon surrender of the bearer Securities with all unpaid coupons relating thereto (except as may otherwise be provided in the Securities) at an agency of the Company maintained for such purpose and upon fulfillment of all other requirements of the agent. (Section 2.07) As of the date of this Prospectus, it is expected that the terms of a series of Securities will not permit registered Securities to be exchanged for bearer Securities.

Defaults and Remedies

Unless the Officers' Certificate or supplemental indenture establishing the series otherwise provides, an "Event of Default" with respect to a series of Securities will occur if:

(1) the Company defaults in any payment of interest on any Securities of the series when the same becomes due and payable and the Default continues for a period of 60 days;

(2) the Company defaults in the payment of the principal of any Securities of the series when the same becomes due and payable at maturity or upon redemption, acceleration or otherwise;

(3) the Company defaults in the payment or satisfaction of any sinking fund obligation with respect to any Securities of a series as required by the Officers' Certificate or supplemental indenture establishing such series and the Default continues for a period of 60 days;

(4) the Company defaults in the performance of any of its other agreements applicable to the series and the Default continues for 90 days after the notice specified below;

(5) the Company pursuant to or within the meaning of any Bankruptcy Law:

(a) commences a voluntary case,

(b) consents to the entry of an order for relief against it in an involuntary case,

(c) consents to the appointment of a Custodian for it or for all or substantially all of its property, or

(d) makes a general assignment for the benefit of its creditors;

(6) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

(a) is for relief against the Company in an involuntary case,

(b) appoints a Custodian for the Company or for all or substantially all of its property, or

(c) orders the liquidation of the Company, and the order or decree remains unstayed and in effect for 60 days; or

(7) there occurs any other Event of Default provided for in the series. (Section 6.01)

The term "Bankruptcy Law" means Title 11, U.S. Code or any similar Federal or State law for the relief of debtors. The term "Custodian" means any receiver, trustee, assignee, liquidator or a similar official under any Bankruptcy Law. (Section 6.01)

"Default" means any event which is, or after notice or passage of time would be, an Event of Default. A Default under subparagraph (4) above is not an Event of Default until the Unsecured Debt Trustee or the Holders of at least 25% in principal amount of the series notify the Company of the Default and the Company does not cure the Default within the time specified after receipt of the notice. (Section 6.01) The Unsecured Debt Trustee may require indemnity reasonably satisfactory to it before it enforces the Unsecured Debt Indenture or the Securities of the series. (Section 7.01) Subject to certain limitations, Holders of a majority in principal amount of the Securities of the series may direct the Unsecured Debt Trustee in its exercise of any trust or power. (Section 6.05) The Unsecured Debt Trustee may withhold from Securityholders of the series notice of any continuing Default (except a Default in payment of principal or interest) if it in good faith determines that withholding notice is in their interest. (Section 7.04) The Company is required to furnish the Unsecured Debt Trustee, not less than annually, a brief certificate as to the Company's compliance with all conditions and covenants under the Unsecured Debt Indenture. (Section 4.04)

The failure to redeem any Securities subject to a Conditional Redemption (as defined) is not an Event of Default if any event on which such redemption is so conditioned does not occur before the redemption date. (Section 6.01)

The Unsecured Debt Indenture does not have a cross-default provision. Thus, a default by the Company on any other debt would not constitute an Event of Default.

Amendments and Waivers

The Unsecured Debt Indenture and the Securities or any coupons of the series may be amended, and any default may be waived as follows: The Securities and the Unsecured Debt Indenture may be amended with the consent of the Holders of not less than a majority in aggregate principal amount of the Securities of all series affected voting as one class. (Section 9.02) A Default on a series may be waived with the consent of the holders of a majority in principal amount of the Securities of the series. (Section 6.04) However, without the consent of each Securityholder affected, no amendment or waiver may (a) reduce the amount of Securities whose Holders must consent to an amendment or waiver, (b) reduce the interest on or change the time for payment of interest on any Security, (c) change the stated maturity of any Security, (d) reduce the principal of any non-Discounted Security or reduce the amount of principal of any Discounted Security that would be due on acceleration thereof, (e) change the currency in which principal or interest on a Security is payable, or (f) waive any Default in payment of interest on or principal of a Security. (Sections 6.04 and 9.02) Without the consent of any Securityholder, the Unsecured Debt Indenture, the Securities or any coupons may be amended to cure any ambiguity, omission, defect or inconsistency; to provide for assumption of Company obligations to Securityholders in the event of a merger or consolidation requiring such assumption; to provide that specific provisions of the Unsecured Debt Indenture shall not apply to a series of Securities not previously issued; to create a series and establish its terms; to provide for a separate Unsecured Debt Trustee for one or more series; or to make any change that does not materially adversely affect the rights of any Securityholder.


(Section 9.01)

Legal Defeasance and Covenant Defeasance

Securities of a series may be defeased in accordance with their terms and, unless the Officers' Certificate or supplemental indenture establishing the terms of the series otherwise provides, as set forth below. The Company at any time may terminate as to a series all of its obligations (except for certain obligations, including obligations with respect to the defeasance trust and obligations to register the transfer or exchange of a Security, to replace destroyed, lost or stolen Securities and coupons and to maintain agencies in respect of the Securities) with respect to the Securities of the series and any related coupons and the Unsecured Debt Indenture ("legal defeasance"). The Company at any time may terminate as to a series its obligations with respect to the Securities and coupons of the series under the covenant described under "Certain Covenants--Limitations on Liens" and any other restrictive covenants which may be applicable to a particular series ("covenant defeasance").

The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. If the Company exercises its legal defeasance option, a series may not be accelerated because of an Event of Default. If the Company exercises its covenant defeasance option, a series may not be accelerated by reference to the covenant described under "Certain Covenants--Limitations on Liens" or any other restrictive covenants which may be applicable to a particular series. (Section 8.01)

To exercise either defeasance option as to a series, the Company must deposit in trust (the "defeasance trust") with the Unsecured Debt Trustee money or U.S. Government Obligations for the payment of principal, premium, if any, and interest on the Securities of the series to redemption or maturity and must comply with certain other conditions. In particular, the Company must obtain an opinion of tax counsel that the defeasance will not result in recognition of any gain or loss to Holders for Federal income tax purposes. "U.S. Government Obligations" are direct obligations of the United States of America which have the full faith and credit of the United States of America pledged for payment and which are not callable at the issuer's option, or certificates representing an ownership interest in such obligations. (Section 8.02)

Regarding the Unsecured Debt Trustee

Firstar Trust Company will act as Unsecured Debt Trustee and Registrar for Securities issued under the Unsecured Debt Indenture and, unless otherwise indicated in a Prospectus Supplement, the Unsecured Debt Trustee will also act as Transfer Agent and Paying Agent with respect to the Securities. (Section 2.03) The Company may remove the Unsecured Debt Trustee with or without cause if the Company so notifies the Unsecured Debt Trustee six months in advance and if no Default occurs during the six-month period. (Section 7.07) The Unsecured Debt Trustee is also one of the trustees under the First Mortgage Indenture for the Company's First Mortgage Bonds, including the New Bonds, and provides services for the Company and certain affiliates, including WPLH. See "Description of the New Bonds--Relationships with the First Mortgage Trustee."

BOOK-ENTRY ONLY SYSTEM

The Debt Securities of any series may be issued initially in the form of one or more global securities under a book-entry only system operated by a securities depositary. Unless otherwise specified in the Prospectus Supplement, the Depository Trust Company ("DTC") will act as securities depositary for the Debt Securities, which would be registered in the name of CEDE & Co., as registered securityholder and nominee for DTC. Individual purchases of Book-Entry Interests (as herein defined) in any such Debt Securities will be made in book-entry form. Purchasers of Book-Entry Interests in such Debt Securities will not receive certificates representing their interests in such Debt Securities. So long as CEDE & Co., as nominee of DTC, is the securityholder, references herein to holders of the Debt Securities or registered owners will mean CEDE & Co., rather than the owners of Book-Entry Interests in Debt Securities.

DTC is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code and a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities deposited by its participants (the "DTC Participants") and facilitates the settlement of securities transactions among DTC Participants in such securities through electronic computerized book-entry changes in accounts of the DTC Participants, thereby eliminating the need for physical movement of securities certificates. Direct DTC Participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, some of whom (including, possibly, the underwriters with respect to the Debt Securities), together with the New York Stock Exchange, Inc., the American Stock Exchange, Inc. and the National Association of Securities Dealers, Inc., own DTC. Access to the DTC system is also available to others such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly (the "Indirect Participants").

DTC Participants purchasing Book-Entry Interests (as defined below) in any Debt Securities will not receive certificates. Each DTC Participant will receive a credit balance in the records of DTC in the amount of such DTC Participant's interest in such Debt Securities, which will be confirmed in accordance with DTC's standard procedures. The ownership interest of each actual purchaser of a Book-Entry Interest in a Debt Security (the "Book-Entry Interests") will be recorded through the records of the DTC Participant or through the records of the Indirect Participant. Owners of Book-Entry Interests should receive from the DTC Participant or Indirect Participant a written confirmation of their purchase providing details of the Book-Entry Interests acquired. Transfers of Book-Entry Interests will be accomplished by book entries made by the DTC Participants or Indirect Participants who act on behalf of the owners of Book-Entry Interests. Owners of Book-Entry Interests will not receive certificates representing their ownership of Book-Entry Interests with respect to any Debt Securities except as described below upon the resignation of DTC.

Under the First Mortgage Indenture and the Unsecured Debt Indenture, payments made by the respective Trustee to DTC or its nominee will satisfy the Company's obligations under the First Mortgage Indenture or the Unsecured Debt Indenture, as the case may be, to the extent of the payments so made. Owners of Book-Entry Interests will not be or be considered by the Company or the respective Trustee to be, and will not have any rights as, holders of New Bonds under the First Mortgage Indenture or Debentures under the Unsecured Debt Indenture, as the case may be.

NEITHER THE COMPANY NOR THE TRUSTEES UNDER THE FIRST MORTGAGE INDENTURE AND UNSECURED DEBT INDENTURE WILL HAVE ANY RESPONSIBILITY OR OBLIGATION TO ANY DTC PARTICIPANT, INDIRECT PARTICIPANT OR ANY OWNER OF A BOOK-ENTRY INTEREST OR ANY OTHER PERSON NOT SHOWN ON THE REGISTRATION BOOKS OF SUCH TRUSTEE AS BEING A HOLDER OF DEBT SECURITIES WITH RESPECT TO: (1) ANY NEW BONDS OR DEBENTURES, AS THE CASE MAY BE; (2) THE ACCURACY OF ANY RECORDS MAINTAINED BY DTC OR ANY DTC PARTICIPANT OR INDIRECT PARTICIPANT; (3) THE PAYMENT BY DTC OR ANY DTC PARTICIPANT OR INDIRECT PARTICIPANT OF ANY AMOUNT DUE TO ANY OWNER OF A BOOK-ENTRY INTEREST IN RESPECT OF THE PRINCIPAL OR REDEMPTION PRICE OF OR INTEREST ON SUCH DEBT SECURITIES; (4) THE DELIVERY BY DTC OR ANY DTC PARTICIPANT OR INDIRECT PARTICIPANT OF ANY NOTICE TO ANY OWNER OF A BOOK-ENTRY INTEREST WHICH IS REQUIRED OR PERMITTED UNDER THE TERMS OF THE FIRST MORTGAGE INDENTURE OR UNSECURED DEBT INDENTURE TO BE GIVEN TO HOLDERS OF NEW BONDS OR DEBENTURES, RESPECTIVELY; (5) THE SELECTION OF THE OWNERS OF A BOOK-ENTRY INTEREST TO RECEIVE PAYMENT IN THE EVENT OF ANY PARTIAL REDEMPTION OF ANY DEBT SECURITIES; OR (6) ANY CONSENT GIVEN OR OTHER ACTION TAKEN BY DTC OR ITS NOMINEE AS HOLDER OF DEBT SECURITIES.

Principal and redemption price of, and interest payments on, Debt Securities registered in the name of DTC or its nominee will be made to DTC or such nominee, as registered owner of such Debt Securities. DTC is responsible for disbursing such payments to the appropriate DTC Participants and such DTC Participants, and any Indirect Participants, are in turn responsible for disbursing the same to the owners of Book-Entry Interests. Unless it has reason to believe it will not receive payment, DTC's current practice is to credit the accounts of the DTC Participants on a payment date in accordance with their respective holdings shown on the records of DTC. Payments by DTC Participants and Indirect Participants to owners of Book-Entry Interests will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in "street name", and will be the responsibility of such DTC Participant or Indirect Participant and not of DTC, the Company or the respective Trustee, subject to any statutory and regulatory requirements as may be in effect from time to time.

DTC Participants and Indirect Participants carry the "position" of the ultimate Book-Entry Interest owner on their records, and will be responsible for providing information to the ultimate Book-Entry Interest owner as to the Debt Securities in which the Book-Entry Interest is held, debt service payments received, and other information. Each person for whom a DTC Participant or Indirect Participant acquires an interest in Debt Securities, as nominee, may desire to make arrangements with such DTC Participant or Indirect Participant to receive a credit balance in the records of such DTC Participant or Indirect Participant, to have all notices of redemption or other communications to or by DTC which may affect such persons forwarded in writing by such DTC Participant or Indirect Participant, and to have notification made of all debt service payments.

Purchases, transfers and sales of Book-Entry Interests by the ultimate Book-Entry Interest owners may be made through book entries made by DTC Participants or Indirect Participants or others who act for the ultimate Book-Entry Interest owner. The respective Trustee under the First Mortgage Indenture and Unsecured Debt Indenture, the Company and the underwriters, as such, have no role in those purchases, transfers or sales.

Owners of Book-Entry Interests may be charged a sum sufficient to cover any tax, fee, or other governmental charge that may be imposed in relation to any transfer or exchange of a Book-Entry Interest.

Each Trustee will recognize and treat DTC (or any successor securities depositary) or its nominee as the holder of Debt Securities registered in its name or the name of its nominee for all purposes, including payment of debt service, notices, enforcement of remedies and voting. Under DTC's current practice, a proxy will be given to the DTC Participants holding Book-Entry Interests in Debt Securities in connection with any matter on which holders of such Debt Securities are asked to vote or give their consent. Crediting of debt service payments and transmittal of notices and other communications by DTC to DTC Participants, by DTC Participants to Indirect Participants and by DTC Participants and Indirect Participants to the ultimate Book-Entry Interest owners are the responsibility of those persons and will be handled by arrangements among them and are not the responsibility of either Trustee, the Company or any underwriter, as such.

Each Trustee, so long as a book-entry system is used for any series of Debt Securities, will send any notice of redemption and any other notices required by the First Mortgage Indenture or Unsecured Debt Indenture to be sent to holders of such New Bonds or Debentures, respectively, only to DTC (or such successor securities depositary) or its nominee. Any failure of DTC to advise any DTC Participant, or of any DTC Participant or Indirect Participant to notify the Book-Entry Interest owner, of any such notice and its content or effect will not affect the validity of the redemption of the Debt Securities called for redemption, or any other action premised on that notice. In the event of a call for redemption, the Trustee's notification to DTC will initiate DTC's standard call process, and, in the event of a partial call, its lottery process by which the call will be randomly allocated to DTC Participants holding positions in the Debt Securities to be redeemed. When DTC and DTC Participants allocate the call for redemption, the owners of the Book- Entry Interests that have been called should be notified by the broker or other person responsible for maintaining the records of those interests and subsequently credited by that person with the proceeds once such Debt Securities are redeemed.

The Company, the Trustees under the First Mortgage Indenture and the Unsecured Debt Indenture and any underwriter or agent cannot and do not give any assurances that DTC, DTC Participants or others will distribute payments of debt service on Debt Securities made to DTC or its nominee as the registered owner, or any redemption or other notices, to the Book-Entry Interest owners, or that they will do so on a timely basis, or that DTC will serve and act in the manner described in this Prospectus.

The Company understands that the current "Rules" applicable to DTC and DTC Participants are on file with the Commission, and that the current "Procedures" of DTC to be followed in dealing with DTC Participants are on file with DTC.

If DTC is at any time unwilling or unable to continue as depositary, and a successor depositary is not appointed by the Company within 90 days, the Company will issue individual certificates to owners of Book-Entry Interests in exchange for the Debt Securities held by DTC or its nominee, as the case may be. In such instance, an owner of a Book- Entry Interest will be entitled to physical delivery of certificates equal in principal amount to such Book-Entry Interest and to have such certificates registered in its name. Individual certificates so issued will be issued in denominations of $1,000 or any multiple thereof.

Neither the Company, the Trustees under the First Mortgage Indenture and the Unsecured Debt Indenture nor any underwriter makes any representation as to the accuracy of the above description of DTC's business, organization and procedures, which is based upon information furnished by DTC.

PLAN OF DISTRIBUTION

The Company may sell the Debt Securities in one or more of the following ways: (a) through underwriters or dealers; (b) directly to a limited number of purchasers or to a single purchaser; or (c) through agents. The Prospectus Supplement with respect to each series of the Debt Securities sets forth, among other things, the terms of the offering of the Debt Securities, including the name or names of the underwriters, dealers or agents, the purchase price of the Debt Securities and proceeds to the Company from such sale, any underwriting discounts and other items constituting underwriters' or agents' compensation and any discounts and commissions allowed or reallowed or paid to dealers and any registered securities exchanges on which the Debt Securities may be listed. Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

If any series of the Debt Securities are sold to underwriters or dealers, the Prospectus Supplement relating thereto will describe the nature of the obligation of the underwriters or dealers to purchase and pay for the Debt Securities. The Debt Securities may be offered to the public either through an underwriting syndicate represented by Merrill Lynch, Pierce, Fenner & Smith Incorporated as managing underwriter, or directly by such firm acting as an underwriter. The underwriter or underwriters with respect to a particular underwritten offering of the Debt Securities will be named in the Prospectus Supplement relating to such offering, and if an underwriting syndicate is used, the managing underwriter or underwriters will be set forth on the cover of such Prospectus Supplement. Unless otherwise set forth in the Prospectus Supplement, the obligations of underwriters to purchase the Debt Securities will be subject to certain conditions precedent and the underwriters will be obligated to purchase all the Debt Securities if any are purchased. The distribution of the Debt Securities by the underwriters may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices.

The Debt Securities may be sold directly by the Company or through agents designated by the Company from time to time. Any agent involved in the offer or sale of the Debt Securities in respect of which this Prospectus is delivered will be named, and any commissions payable by the Company to such agent will be set forth, in the Prospectus Supplement relating thereto. Unless otherwise indicated in the Prospectus Supplement, any such agent is acting on a best efforts basis for the period of its agency.

Underwriters, dealers or agents designated by the Company in connection with the distribution of the Debt Securities may be entitled to indemnification by the Company against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribution with respect to payments which the underwriters or agents may be required to make in respect thereof.

In the event that the Debt Securities are not listed on a registered national securities exchange, certain broker-dealers may make a market in the Debt Securities, but will not be obligated to do so and may discontinue any market-making at any time without notice. No assurance can be given that any broker-dealer will make a market in the Debt Securities or as to the liquidity of the trading market for the Debt Securities, whether or not the Debt Securities are listed on a registered national securities exchange. The Prospectus Supplement with respect to any series of the Debt Securities will state, if known, whether or not any broker-dealer intends to make a market in the Debt Securities. If no such determination has been made, the Prospectus Supplement will so state.

LEGAL OPINIONS

The validity of the Debt Securities will be passed upon for the Company by Foley & Lardner, Milwaukee, Wisconsin. Certain legal matters will be passed upon for the underwriters, dealers, purchasers or agents by Chadbourne & Parke LLP, New York, New York.

Item 15. Indemnification of Directors and Officers.

Pursuant to the provisions of the Wisconsin Business Corporation Law and Article X of the Registrant's Bylaws, directors and officers of the Registrant are entitled to mandatory indemnification from the Registrant against certain liabilities (which may include liabilities under the Securities Act of 1933) and expenses (i) to the extent such officers or directors are successful in the defense of a proceeding; and
(ii) in proceedings in which the director or officer is not successful in defense thereof, unless it is determined that the director or officer breached or failed to perform his or her duties to the Registrant and such breach or failure constituted: (a) a willful failure to deal fairly with the Registrant or its shareholders in connection with a matter in which the director or officer had a material conflict of interest; (b) a violation of criminal law unless the director or officer had a reasonable cause to believe his or her conduct was lawful or had no reasonable cause to believe his or her conduct was unlawful; (c) a transaction from which the director or officer derived an improper personal profit; or (d) willful misconduct. Additionally, under the Wisconsin Business Corporation Law, directors of the Registrant are not subject to personal liability to the Registrant, its shareholders or any person asserting rights on behalf thereof, for certain breaches or failures to perform any duty resulting solely from their status as directors, except in circumstances paralleling those outlined in (a) through (d) above.

The indemnification provided by the Wisconsin Business Corporation Law and the Registrant's Bylaws is not exclusive of any other rights to which a director or officer of the Registrant may be entitled. The Registrant also carries directors' and officers' liability insurance.

The proposed forms of Underwriting Agreements for the Debt Securities contain provisions under which the underwriters agree to indemnify the directors and officers of the Registrant against certain liabilities, including liabilities under the Securities Act of 1933.

Item 16. Exhibits.

The exhibits listed in the accompanying Exhibit Index are filed (except where otherwise indicated) as part of this Registration Statement.

Item 17. Undertakings.

(a) The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement;

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;

Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Registration Statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or
Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the Registration Statement shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) The undersigned Registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this Registration Statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this Registration Statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(d) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.


SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this amendment to the Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Madison, State of Wisconsin, on June 23, 1997.

(24) any terms that may be required by or advisable under U.S. or other applicable laws; and

(25) any other terms not inconsistent with this Indenture.

All Securities of one series need not be issued at the same time and, unless otherwise provided, a series may be reopened for issuances of additional Securities of such series.

The creation and issuance of a series and the authentication and delivery thereof are not subject to any conditions precedent.

SECTION 2.02. Execution and Authentication.

Two Officers shall sign the Securities on behalf of the Company by manual or facsimile signature. The Company's seal shall be reproduced on the Securities, which seal may be affixed or in facsimile form. An Officer shall sign any coupons by facsimile signature.

If an Officer whose signature is on a Security or its coupons no longer holds that office at the time the Security is authenticated or delivered, the Security and coupons shall nevertheless be valid.

A Security and its coupons shall not be valid until the Security is authenticated by the manual signature of an authorized signatory of the Registrar. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture.

Each Registered Security shall be dated the date of its authentication. Each Bearer Security shall be dated the date of its authentication or as provided in the Officers' Certificate or supplemental indenture establishing the series.

Securities may have notations, legends or endorsements required by law, stock exchange rule, agreement or usage, which shall be provided to the Trustee in writing by the Company.

In the event Securities are issued in electronic or other uncertificated form, such Securities may be validly issued without the signatures or seal contemplated by this Section 2.02.

SECTION 2.03. Securities Agents.

The Company shall maintain an office or agency where Securities may be authenticated ("Registrar"), where Securities may be presented for registration of transfer or for exchange ("Transfer Agent") and where Securities may be presented for payment ("Paying Agent"). Whenever the Company must issue or deliver Securities pursuant to this Indenture, the Registrar shall authenticate the Securities at the Company's request. The Transfer Agent shall keep a register of the Securities and of their transfer and exchange.

The Trustee shall be, and is hereby appointed as, the Registrar. The Company may appoint more than one Transfer Agent or Paying Agent for a series. The Company shall notify the Trustee of the name and address of any Agent not a party to this Indenture. If the Company fails to maintain a Transfer Agent or Paying Agent for a series, the Trustee shall act as such.

SECTION 2.04. Bearer Securities.

U.S. laws and Treasury Regulations restrict sales or exchanges of and payments on Bearer Securities. Therefore, except as provided below:

(1) Bearer Securities will be offered, sold and delivered only outside the United States and will be delivered only upon presentation of a certificate in a form prescribed by the Company to comply with U.S. laws and regulations.

(2) Bearer Securities will not be issued in exchange for Registered Securities.

(3) All payments of principal and interest (including original issue discount) on Bearer Securities will be made outside the United States by a Paying Agent located outside the United States unless the Company determines that:

(A) such payments may not be made by such Paying Agent because the payments are illegal or prevented by exchange controls as described in Treasury Regulation section 1.163-5(c)(2)(v); and

(B) making the payments in the United States would not have an adverse tax effect on the Company.

If there is a change in the relevant provisions of U.S. laws or Treasury Regulations or the judicial or administrative interpretation thereof, a restriction set forth in paragraph (1), (2) or (3) above will not apply to a series if the Company determines that the relevant provisions no longer apply to the series or that failure to comply with the relevant provisions would not have an adverse tax effect on the Company or on Securityholders or cause the series to be treated as "registration-required" obligations under U.S. law.

The Company shall notify the Trustee in writing of any determinations by the Company under this Section.

"Treasury Regulations" means regulations of the U.S. Treasury Department under the Internal Revenue Code of 1986, as amended.

SECTION 2.05. Paying Agent to Hold Money in Trust.

The Company shall require each Paying Agent for a series other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of the persons entitled thereto all money held by the Paying Agent for the payment of principal of or interest on the series, and will notify the Trustee in writing of any default by the Company in making any such payment.

While any such default continues, the Trustee may require a Paying Agent to pay all money so held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent shall have no further liability for the money.

If the Company or an Affiliate acts as Paying Agent for a series, it shall segregate and hold as a separate trust fund all money held by it as Paying Agent for the series.

SECTION 2.06. Securityholder Lists.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Securityholders. If the Trustee is not the Transfer Agent, the Company shall furnish to the Trustee semiannually and at such other times as the Trustee may request a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders of Registered Securities and Holders of Bearer Securities whose names are on the list referred to below.

The Transfer Agent shall keep a list of the names and addresses of Holders of Bearer Securities who file a request to be included on such list. A request will remain in effect for two years but successive requests may be made.

Whenever the Company or the Trustee is required to mail a notice to all Holders of Registered Securities of a series, it also shall mail the notice to Holders of Bearer Securities of the series whose names are on the list, if any.

Whenever the Company is required to publish a notice to all Holders of Bearer Securities of a series, it also shall mail the notice to such of them whose names are on the list, if any.

SECTION 2.07. Transfer and Exchange.

When Registered Securities of a series are presented to the Transfer Agent with a request to register a transfer or to exchange them for an equal principal amount of Registered Securities of other denominations of the series, the Transfer Agent shall register the transfer or make the exchange if its requirements for such transactions are met. When Bearer Securities of a series are presented to the Transfer Agent with a request to exchange them for an equal principal amount of Bearer Securities of other denominations of the series, the Transfer Agent shall make the exchange if its requirements for such transactions are met.

The Transfer Agent may require a Holder to pay a sum sufficient to cover any taxes imposed on a transfer or exchange.

If a series provides for Registered and Bearer Securities and for their exchange, Bearer Securities may be exchanged for Registered Securities and Registered Securities may be exchanged for Bearer Securities as provided in the Securities or the Officers' Certificate or supplemental indenture establishing the series if the requirements of the Transfer Agent for such transactions are met and if Section 2.04 permits the exchange.

SECTION 2.08. Replacement Securities.

If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. If the Holder of a Security or coupon claims that it has been lost, destroyed or wrongfully taken, then, in the absence of notice to the Company or the Trustee that the Security or coupon has been acquired by a bona fide purchaser, the Company shall issue a replacement Security or coupon of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding if the Company and the Trustee receive:

(1) evidence satisfactory to them of the loss, destruction or taking of the Security or coupon;

(2) such security or indemnity bond satisfactory to them to save each of them and any agent of either of them harmless; and

(3) payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

A replacement Security shall have coupons attached corresponding to those, if any, on the replaced Security.

Every replacement Security or coupon is an additional obligation of the Company.

In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security or coupon, pay such Security.

SECTION 2.09. Outstanding Securities.

The Securities outstanding at any time are all the Securities authenticated by the Registrar except for those canceled by it, those delivered to it for cancellation, and those described in this Section as not outstanding.

If a Security is replaced pursuant to Section 2.08, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a bona fide purchaser.

If Securities are considered paid under Section 4.01, they cease to be outstanding and interest on them ceases to accrue.

A Security does not cease to be outstanding because the Company or an Affiliate holds the Security.

SECTION 2.10. Discounted Securities.

In determining whether the Holders of the required principal amount of Securities have concurred in any direction, waiver or consent, the principal amount of a Discounted Security shall be the amount of principal that would be due as of the date of such determination if payment of the Security were accelerated on that date.

SECTION 2.11. Treasury Securities.

In determining whether the Holders of the required principal amount of Securities have concurred in any direction, waiver or consent, Securities owned by the Company or an Affiliate shall be disregarded, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities for which the Trustee has received an Officers' Certificate stating that such Securities are so owned shall be so disregarded.

SECTION 2.12. Global Securities.

If the Officers' Certificate or supplemental indenture establishing a series so provides, the Company may issue some or all of the Securities of the series in temporary or permanent global form. A global Security may be in registered form, in bearer form with or without coupons or in uncertificated form. A global Security shall represent that amount of Securities of a series as specified in the global Security or as endorsed thereon from time to time. At the Company's request, the Registrar shall endorse a global Security to reflect the amount of any increase or decrease in the Securities represented thereby.

The Company may issue a global Security only to a depositary designated by the Company. A depositary may transfer a global Security only as a whole to its nominee or to a successor depositary.

The Officers' Certificate or supplemental indenture establishing a series may establish, among other things, the manner of paying principal and interest on a global Security and whether and upon what terms a beneficial owner of an interest in a global Security may exchange such interest for definitive Securities.

The Company, an Affiliate, the Trustee and any Agent shall not be responsible for any acts or omissions of a depositary, for any depositary records of beneficial ownership interests or for any transactions between the depositary and beneficial owners.

SECTION 2.13. Temporary Securities.

Until definitive Securities of a series are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Temporary Securities may be in global form. Temporary Bearer Securities may have one or more coupons or no coupons. Without unreasonable delay, the Company shall deliver definitive Securities in exchange for temporary Securities. Until such exchange, temporary Securities shall be entitled to the same rights, benefits and privileges as definitive Securities.

SECTION 2.14. Cancellation.

The Company at any time may deliver Securities to the Registrar for cancellation. The Transfer Agent and the Paying Agent shall forward to the Registrar any Securities and coupons surrendered to them for payment, exchange or registration of transfer. The Registrar shall cancel all Securities or coupons surrendered for payment, registration of transfer, exchange or cancellation as follows: the Registrar will cancel all Registered Securities and matured coupons. The Registrar also will cancel all Bearer Securities and unmatured coupons unless the Company requests the Registrar to hold the same for redelivery. Any Bearer Securities so held shall be considered delivered for cancellation under
Section 2.09. The Registrar shall destroy canceled Securities and coupons and deliver a certificate of cancellation thereof to the Company unless the Company otherwise directs.

Unless the Officers' Certificate or supplemental indenture establishing a series otherwise provides, the Company may not issue new Securities to replace Securities that the Company has paid or that the Company has delivered to the Registrar for cancellation.

SECTION 2.15. Defaulted Interest.

If the Company defaults in a payment of interest on Registered Securities, it need not pay the defaulted interest to Holders on the regular record date. The Company may fix a special record date for determining Holders entitled to receive defaulted interest or the Company may pay defaulted interest in any other lawful manner.

ARTICLE 3--REDEMPTION

SECTION 3.01. Notices to Trustee.

Securities of a series that are redeemable before maturity shall be redeemable in accordance with their terms and, unless the Officers' Certificate or supplemental indenture establishing the series otherwise provides, in accordance with this Article.

In the case of a redemption by the Company, the Company shall notify the Trustee of the redemption date and the principal amount of Securities to be redeemed. The Company shall notify the Trustee at least 35 days before the redemption date unless a shorter notice is satisfactory to the Trustee.

If the Company is required to redeem Securities, it may reduce the principal amount of Securities required to be redeemed to the extent it is permitted a credit by the terms of the Securities and it notifies the Trustee of the amount of the credit and the basis for it. If the reduction is based on a credit for acquired or redeemed Securities that the Company has not previously delivered to the Registrar for cancellation, the Company shall deliver the Securities at the same time as the notice.

SECTION 3.02. Selection of Securities to Be Redeemed.

If less than all the Securities of a series are to be redeemed, the Trustee shall select the Securities to be redeemed pro rata or by any other method the Trustee considers fair and appropriate. The Trustee shall make the selection from Securities of the series outstanding not previously called for redemption. The Trustee may select for redemption portions of the principal of Securities having denominations larger than the minimum denomination for the series. Securities and portions thereof selected for redemption shall be in amounts equal to the minimum denomination for the series or an integral multiple thereof. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption.

SECTION 3.03. Notice of Redemption.

At least 30 days but not more than 60 days before a redemption date, the Company shall mail a notice of redemption by first-class mail to each Holder of Registered Securities whose Securities are to be redeemed.

If Bearer Securities are to be redeemed, the Company shall publish a notice of redemption in an Authorized Newspaper as provided in the Securities.

A notice of redemption shall identify the Securities of the series to be redeemed and shall state:

(1) the redemption date;

(2) the redemption price;

(3) the name and address of the Paying Agent;

(4) that Securities called for redemption, together with all coupons, if any, maturing after the redemption date, must be surrendered to the Paying Agent to collect the redemption price;

(5) that, unless the Company defaults in making the redemption payment, interest on Securities called for redemption ceases to accrue on and after the redemption date;

(6) whether the redemption by the Company is mandatory or optional; and

(7) whether the redemption is conditional as provided in
Section 3.04, the terms of the condition, and that, if the condition is not satisfied or is not waived by the Company, the Securities will not be redeemed and such a failure to redeem will not constitute an Event of Default.

At the Company's request, the Trustee shall give the notice of redemption in the Company's name and at its expense.

SECTION 3.04. Effect of Notice of Redemption.

Except as provided below, once notice of redemption is given, Securities called for redemption become due and payable on the redemption date at the redemption price stated in the notice.

A notice of redemption may provide that it is subject to the occurrence of any event before the date fixed for such redemption as described in such notice ("Conditional Redemption") and such notice of Conditional Redemption shall be of no effect unless all such conditions to the redemption have occurred before such date or have been waived by the Company.

SECTION 3.05. Payment of Redemption Price.

On or before the redemption date, the Company shall deposit with the Paying Agent money sufficient to pay the redemption price of and accrued interest on all Securities to be redeemed on that date.

When the Holder of a Security surrenders it for redemption in accordance with the redemption notice, the Company (through the Paying Agent) shall pay to the Holder on the redemption date the redemption price and accrued interest to such date, except that:

(1) the Company will pay any such interest (except defaulted interest) to Holders on the record date of Registered Securities if the redemption date occurs on an interest payment date; and

(2) the Company will pay any such interest to Holders of coupons that mature on or before the redemption date upon surrender of such coupons to the Paying Agent.

Coupons maturing after the redemption date on a called Security are void absent a payment default on that date. Nevertheless, if a Holder surrenders for redemption a Bearer Security missing any such coupons, the Company may deduct the face amount of such coupons from the redemption price. If thereafter the Holder surrenders to the Paying Agent the missing coupons, the Company will return the amount so deducted. The Company also may waive surrender of the missing coupons if it receives an indemnity bond satisfactory to the Company.

SECTION 3.06. Securities Redeemed in Part.

Upon surrender of a Security that is redeemed in part, the Company shall deliver to the Holder of such Security, without service charge, a new Security of the same series equal in principal amount to, and in exchange for, the unredeemed portion of the Security surrendered.

ARTICLE 4--COVENANTS

SECTION 4.01. Payment of Securities.

The Company shall pay the principal of and interest on a series in accordance with the terms of the Securities for the series, any related coupons, and this Indenture. On each payment date, the Company shall have deposited with the Paying Agent in funds which are then immediately available money sufficient to pay all principal and interest then due on the series. Principal and interest on a series shall be considered paid on the date due if the Paying Agent for the series holds on that date money sufficient to pay all principal and interest then due on the series.

SECTION 4.02. Overdue Interest.

Unless the Officers' Certificate or supplemental indenture establishing a series otherwise provides, the Company shall pay interest on overdue principal of a Security of a series at the rate (or Yield to Maturity in the case of a Discounted Security) borne by the series; it shall pay interest on overdue installments of interest at the same rate or Yield to Maturity to the extent lawful.

SECTION 4.03. No Lien Created, etc.

This Indenture and the Securities do not create a Lien, charge or encumbrance on any property of the Company or any Subsidiary.

SECTION 4.04. Compliance Certificate.

The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Company, a brief certificate signed by the principal executive officer, principal financial officer or principal accounting officer of the Company, as to the signer's knowledge of the Company's compliance with all conditions and covenants under this Indenture (determined without regard to any period of grace or requirement of notice provided herein).

Any other obligor on the Securities also shall deliver to the Trustee such a certificate similarly signed as to its compliance with this Indenture within 120 days after the end of each of its fiscal year.

The certificates need not comply with Section 10.04.

SECTION 4.05. SEC Reports.

The Company shall provide to the Trustee, within 15 days after the Company is required to file the same with the SEC, copies of the annual reports and of the information, documents, and other reports (or such portions of the foregoing as the SEC may prescribe) which the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934.

Any other obligor on the Securities shall do likewise as to the above items which it is required to file with the SEC pursuant to those Sections.

SECTION 4.07. Limitations on Liens.

So long as there remain outstanding any Securities of any series to which this Section 4.07 applies under the terms of the series, the Company will not, and will not permit any Subsidiary to, create or suffer to be created or to exist any Lien on any of its properties or assets now owned or hereafter acquired to secure any indebtedness, without making effective provision whereby the Securities (together with, if the Company shall so determine, any other debt of the Company or any Subsidiary then existing or thereafter created that is not subordinate to such Securities) of such series shall be equally and ratably secured with (or prior to) any and all such indebtedness and with any other indebtedness similarly entitled to be equally and ratably secured. However, this restriction shall not apply to or prevent the creation or existence of:

ARTICLE 5--SUCCESSORS

SECTION 5.01. Consolidations and Mergers of Company and Conveyances Permitted Subject to Certain Conditions.

Unless the Officers' Certificate or supplemental indenture establishing a series otherwise provides, the Company shall not consolidate with, or sell or convey all or substantially all of its assets to, or merge with or into any other Person unless (i) either the Company shall be the continuing corporation, or the Person shall be a Person organized and existing under the laws of the United States of America or a state thereof and the Person shall expressly assume the due and punctual payment of the principal of and interest on all the Securities and any coupons and the due and punctual performance and observance of all of the covenants and conditions of the Company under this Indenture by supplemental indenture satisfactory to the Trustee, executed and delivered to the Trustee by such Person; (ii) the Company or the Person, as the case may be, shall not, immediately after the merger or consolidation, or the sale or conveyance, be in default in the performance of any such covenant or condition; and (iii) after giving effect to the transaction, no event which, after notice or lapse of time, would become a Default shall have occurred or be continuing.

SECTION 5.02. Rights and Duties of Successor Corporation.

In case of any such consolidation, merger, sale or conveyance and upon any such assumption by a Person, such Person shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as the party of the first part, and the Company shall be relieved of any further obligation under this Indenture, Securities and any coupons. Such Person thereupon may cause to be signed, and may issue either in its own name or in the name of the Company, any or all of the Securities issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such Person instead of the Company, and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver any Securities which previously shall have been signed and delivered by the officers of the Company to the Trustee for authentication, and any Securities which such Person thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Securities of any series so issued shall in all respects have the same legal rank and benefit under this Indenture as the Securities of that series theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Securities had been issued at the date of the execution hereof.

In case of any such consolidation, merger, sale or conveyance such changes in phraseology and form (but not in substance) may be made in the Securities thereafter to be issued as may be appropriate.

SECTION 5.03. Officers' Certificate and Opinion of Counsel.

The Trustee may receive an Officers' Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale or conveyance, and any such assumption, complies with the provisions of this Article Five.

ARTICLE 6--DEFAULTS AND REMEDIES

SECTION 6.01. Events of Default.

Unless the Officers' Certificate or supplemental indenture establishing a series otherwise provides, an "Event of Default" on the series so established occurs if:

(1) the Company defaults in any payment of interest on any Securities of the series when the same becomes due and payable and the Default continues for a period of 60 days;

(2) the Company defaults in the payment of the principal of any Securities of the series when the same becomes due and payable at maturity or upon redemption, acceleration or otherwise;

(3) the Company defaults in the payment or satisfaction of any sinking fund obligation with respect to any Securities of a series as required by the Officers' Certificate or supplemental indenture establishing such series and the Default continues for a period of 60 days;

(4) the Company defaults in the performance of any of its other agreements applicable to the series and the Default continues for 90 days after the notice specified below;

(5) the Company pursuant to or within the meaning of any Bankruptcy Law:

(A) commences a voluntary case,

(B) consents to the entry of an order for relief against it in an involuntary case,

(C) consents to the appointment of a Custodian for it or for all or substantially all of its property, or

(D) makes a general assignment for the benefit of its creditors;

(6) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

(A) is for relief against the Company in an involuntary case,

(B) appoints a Custodian for the Company or for all or substantially all of its property, or

(C) orders the liquidation of the Company,

and the order or decree remains unstayed and in effect for 60 days; or

(7) there occurs any other Event of Default provided for in the series.

The term "Bankruptcy Law" means Title 11, U.S. Code or any similar Federal or State law for the relief of debtors. The term "Custodian" means any receiver, trustee, assignee, liquidator or a similar official under any Bankruptcy Law.

A Default under clause (4) is not an Event of Default until the Trustee or the Holders of at least 25% in principal amount of the series notify the Company of the Default and the Company does not cure the Default within the time specified after receipt of the notice. The notice must specify the Default, demand that it be remedied and state that the notice is a "Notice of Default." If Holders notify the Company of a Default, they shall notify the Trustee at the same time.

The failure to redeem any Security subject to a Conditional Redemption is not an Event of Default if any event on which such redemption is so conditioned does not occur before the redemption date.

SECTION 6.02. Acceleration.

If an Event of Default occurs and is continuing on a series, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the series by notice to the Company and the Trustee, may declare the principal of and accrued interest on all the Securities of the series to be due and payable immediately. Discounted Securities may provide that the amount of principal due upon acceleration is less than the stated principal amount.

The Holders of a majority in principal amount of the series by notice to the Trustee may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default on the series have been cured or waived except nonpayment of principal or interest that has become due solely because of the acceleration.

SECTION 6.03. Other Remedies.

If an Event of Default occurs and is continuing on a series, the Trustee may pursue any available remedy to collect principal or interest then due on the series, to enforce the performance of any provision applicable to the series, or otherwise to protect the rights of the Trustee and Holders of the series.

The Trustee may maintain a proceeding even if it does not possess any of the Securities or coupons or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

SECTION 6.04. Waiver of Past Defaults.

The Holders of a majority in principal amount of a series by notice to the Trustee may waive an existing Default on the series and its consequences except:

(1) a Default in the payment of the principal of or interest on the series, or

(2) a Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Securityholder affected.

SECTION 6.05. Control by Majority.

The Holders of a majority in principal amount of a series may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or of exercising any trust or power conferred on the Trustee, with respect to the series. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture.

SECTION 6.06. Limitation on Suits.

A Securityholder of a series may pursue a remedy with respect to the series only if:

(1) the Holder gives to the Trustee notice of a continuing Event of Default on the series;

(2) the Holders of at least 25% in principal amount of the series make a request to the Trustee to pursue the remedy;

(3) such Holder or Holders offer to the Trustee indemnity reasonably satisfactory to the Trustee against any loss, liability or expense;

(4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and

(5) during such 60-day period the Holders of a majority in principal amount of the series do not give the Trustee a direction inconsistent with such request.

A Securityholder may not use this Indenture to prejudice the rights of another Securityholder or to obtain a preference or priority over another Securityholder.

SECTION 6.07. Collection Suit by Trustee.

If an Event of Default in payment of interest, principal or sinking fund payment specified in Section 6.01(1), (2) or (3) occurs and is continuing on a series, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal and interest remaining unpaid on the series.

SECTION 6.08. Priorities.

If the Trustee collects any money for a series pursuant to this Article, it shall pay out the money in the following order:

First: to the Trustee for amounts due under Section 7.06;

Second: to Securityholders of the series for amounts due and unpaid for principal and interest, ratably, without preference or priority of any kind, according to the amounts due and payable for principal and interest, respectively; and

Third: to the Company.

The Trustee may fix a payment date for any payment to Securityholders.

ARTICLE 7--TRUSTEE

SECTION 7.01. Rights of Trustee.

(1) The Trustee may rely on any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document.

(2) Before the Trustee acts or refrains from acting, it may require an Officers' Certificate or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on the Officers' Certificate or Opinion of Counsel.

(3) The Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care.

(4) The Trustee shall not be liable for any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05 other than any liabilities arising out of its own negligence.

(5) The Trustee may refuse to perform any duty or exercise any right or power which it reasonably believes may expose it to any loss, liability or expense unless it receives indemnity reasonably satisfactory to it against such loss, liability or expense.

(6) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

(7) The Trustee shall have no duty with respect to a Default unless a Trust Officer has received written notice of such Default.

(8) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized and within its powers other than liabilities arising out of its own negligence.

(9) Any Agent shall have the same rights and be protected to the same extent as if it were Trustee.

SECTION 7.02. Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Securities or coupons and may otherwise deal with the Company or an Affiliate with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights.

SECTION 7.03. Trustee's Disclaimer.

The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities or any coupons; it shall not be accountable for the Company's use of the proceeds from the Securities; it shall not be responsible for any statement in the Securities or any coupons other than the Trustee's certificate of authentication; it shall not be responsible for any overissue; it shall not be responsible for determining whether the form and terms of any Securities or coupons were established in conformity with this Indenture; and it shall not be responsible for determining whether any Securities were issued in accordance with this Indenture.

SECTION 7.04. Notice of Defaults.

If a Default occurs and is continuing on a series and if it is known to the Trustee, the Trustee shall mail a notice of the Default within 90 days after it occurs to Holders of Registered Securities of the series. Except in the case of a Default in payment on a series, the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is in the interest of Holders of the series. The Trustee shall withhold notice of a Default described in Section 6.01(4) until at least 90 days after it occurs.

SECTION 7.05. Reports by Trustee to Holders.

Any report required by TIA Section 313(a) to be mailed to Securityholders shall be mailed by the Trustee on or before July 15 of each year.

A copy of each report at the time of its mailing to Securityholders shall be filed with the SEC and each stock exchange on which any Securities are listed. The Company shall notify the Trustee when any Securities are listed on a stock exchange.

SECTION 7.06. Compensation and Indemnity.

The Company shall pay to the Trustee from time to time reasonable compensation for its services. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred by it. Such expenses shall include the reasonable compensation and expenses of the Trustee's agents and counsel.

The Company shall indemnify the Trustee (including its officers, directors and employees) for, and hold it harmless against, any loss, expense or liability incurred by it arising out of or in connection with the acceptance or administration of this Indenture or the trusts hereunder or the performance of its duties hereunder or under any related document, including the reasonable costs and expenses of defending itself against or investigating any claim or liability with respect to the Securities. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent.

The Company need not reimburse any expense or indemnify against any loss or liability incurred by the Trustee through negligence, willful misconduct or bad faith.

To secure the Company's payment obligations in this Section, the Trustee shall have a Lien prior to the Securities and any coupons on all money or property held or collected by the Trustee, except that held in trust to pay principal or interest on particular Securities.

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(5) or (6) occurs, such expenses and the compensation for such services are intended to constitute expenses of administration under any Bankruptcy Law.

The provisions of this Section shall survive any termination or discharge of this Indenture (including without limitation any termination under any Bankruptcy Law) and the resignation or removal of the Trustee.

SECTION 7.07. Replacement of Trustee.

A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee's acceptance of appointment as provided in this Section.

The Trustee may resign by so notifying the Company. The Holders of a majority in principal amount of the Securities may remove the Trustee by so notifying the Trustee and may appoint a successor Trustee with the Company's consent.

The Company may remove the Trustee if:

(1) the Trustee fails to comply with TIA Section 310(a) or TIA
Section 310(b) or with Section 7.09;

(2) the Trustee is adjudged a bankrupt or an insolvent;

(3) a Custodian or other public officer takes charge of the Trustee or its property;

(4) the Trustee becomes incapable of acting; or

(5) an event of the kind described in Section 6.01(5) or (6) occurs with respect to the Trustee.

The Company also may remove the Trustee with or without cause if the Company so notifies the Trustee six months in advance and if no Default occurs or is continuing during the six-month period.

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee.

If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of a majority in principal amount of the Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee fails to comply with TIA Section 310(a) or TIA
Section 310(b) or with Section 7.09, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders of Registered Securities. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the Lien provided for in Section 7.06.

SECTION 7.08. Successor Trustee by Merger, etc.

If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee.

SECTION 7.09. Trustee's Capital and Surplus.

The Trustee at all times shall have a combined capital and surplus of at least $10,000,000 as set forth in its most recent published report of condition.

ARTICLE 8--DISCHARGE OF INDENTURE

SECTION 8.01. Defeasance.

Securities of a series may be defeased in accordance with their terms and, unless the Officers' Certificate or supplemental indenture establishing the series otherwise provides, in accordance with this Article.

The Company at any time may terminate as to a series all of its obligations under this Indenture, the Securities of a series and any related coupons ("legal defeasance option"). The Company at any time may terminate as to a series its obligations, if any, under Section 4.07 and any other restrictive covenants which may be applicable to a particular series ("covenant defeasance option"). However, in the case of the legal defeasance option, the Company's obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 7.06, 7.07 and 8.04 shall survive until the Securities of the series are no longer outstanding; thereafter the Company's obligations in Section 7.06 shall survive.

The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. If the Company exercises its legal defeasance option, a series may not be accelerated because of an Event of Default. If the Company exercises its covenant defeasance option, a series may not be accelerated by reference to Section 4.07 or any other restrictive covenants which may be applicable to a particular series so defeased under the terms of the series.

The Trustee upon request shall acknowledge in writing the discharge of those obligations that the Company terminates.

SECTION 8.02. Conditions to Defeasance.

The Company may exercise as to a series its legal defeasance option or its covenant defeasance option if:

(1) the Company irrevocably deposits in trust with the Trustee or another trustee money or U.S. Government Obligations;

(2) the Company delivers to the Trustee a certificate from a nationally recognized firm of independent accountants expressing their opinion that the payments of principal and interest when due on the deposited U.S. Government Obligations without reinvestment plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay principal and interest when due on all the Securities of the series to maturity or redemption, as the case may be;

(3) immediately after the deposit no Default exists;

(4) the deposit does not constitute a default under any other agreement binding on the Company;

(5) the deposit does not cause the Trustee to have a conflicting interest under TIA Section 310(a) or TIA
Section 310(b) as to another series;

(6) the Company delivers to the Trustee an Opinion of Counsel to the effect that Holders of the series will not recognize income, gain or loss for Federal income tax purposes as a result of the defeasance; and

(7) 91 days pass after the deposit is made and during the 91-day period no Default specified in Section 6.01(5) or
(6) occurs that is continuing at the end of the period.

Before or after a deposit the Company may make arrangements satisfactory to the Trustee for the redemption of Securities at a future date in accordance with Article 3.

"U.S. Government Obligations" means securities which are direct obligations of (i) the United States or (ii) an agency or instrumentality of the United States, the payment of which is unconditionally guaranteed by the United States, which, in either case, have the full faith and credit of the United States pledged for payment and are not callable at the issuer's option, or certificates representing an ownership interest in such obligations.

SECTION 8.03. Application of Trust Money.

The Trustee shall hold in trust money or U.S. Government Obligations deposited with it pursuant to Section 8.02. It shall apply the deposited money and the money from U.S. Government Obligations through the Paying Agent and in accordance with this Indenture to the payment of principal and interest on Securities of the defeased series.

SECTION 8.04. Repayment to Company.

The Trustee and the Paying Agent shall promptly turn over to the Company upon request any excess money or securities held by them at any time.

The Trustee and the Paying Agent shall pay to the Company upon request any money held by them for the payment of principal or interest that remains unclaimed for two years. After payment to the Company, Securityholders entitled to the money must look to the Company for payment as unsecured general creditors unless an abandoned property law designates another person.

ARTICLE 9--SUPPLEMENTAL INDENTURES

SECTION 9.01. Supplemental Indentures Without Consent of Holders.

Without the consent of any Holders, the Company, when authorized by or pursuant to one or more Board Resolutions, and the Trustee, at any time and from time to time, may enter into one or more indentures supplemental hereto, in form satisfactory to the Trustee and the Company, for any of the following purposes:

(1) to evidence the succession of another Person to the Company and the assumption by any such successor of the covenants of the Company herein and in the Securities; or

(2) to add to the covenants of the Company for the benefit of the Holders of all or any series of Securities (and if such covenants are to be for the benefit of less than all series of Securities, stating that such covenants are expressly being included solely for the benefit of such series) or to surrender any right or power herein conferred upon the Company; or

(3) to add to or change any of the provisions of this Indenture to such extent as shall be necessary to permit or facilitate the issuance of Securities of any series in bearer form, registrable or not registrable as to principal, and with or without interest coupons, or to permit or facilitate the issuance of Securities of any series in uncertificated form; or

(4) to add to, change or eliminate any of the provisions of this Indenture in respect of one or more series of Securities; provided, however, that any such addition, change or elimination shall either (i) not adversely affect the rights of the Holders of series of Securities in any material respect, or (ii) not apply to any series of Securities created prior to the execution of such supplemental indenture where such addition, change or elimination has an adverse effect on the rights of the Holders of such Securities in any material respect; or

(5) to secure the Securities of any series; or

(6) to establish the form or terms of Securities of any series as permitted pursuant to this Indenture; or

(7) to evidence and provide for the acceptance of appointment hereunder by a successor Trustee with respect to the Securities of one or more series and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee; or

(8) to cure any ambiguity or defect in and to correct or supplement any provision in this Indenture or any Security of any series that may be inconsistent with any other provision in this Indenture or in the Security of such series, or to make any other provisions with respect to matters or questions arising under this Indenture; provided, however, that any such action pursuant to this clause (8) shall not adversely affect the rights of the Holders of Securities of any series in any material respect; or

(9) to modify, eliminate or add to the provisions of this Indenture to such extent as shall be necessary to effect qualification of this Indenture under the TIA, or under any similar federal statute hereafter enacted, and to add to this Indenture such other provisions as may be expressly permitted by the TIA; or

(10) to amend or supplement the restrictions on and procedures for resale, attempted resale and other transfers of any series of Securities to reflect any change in applicable law or regulation (or interpretation thereof) or in practices relating thereto.

SECTION 9.02. Supplemental Indentures With Consent of Holders.

With the consent of the Holders of not less than a majority in aggregate principal amount of the Securities of all series of Securities affected by such supplemental indenture (voting as one class), by the act of said Holders delivered to the Company and the Trustee, the Company, when authorized by or pursuant to a Board Resolution, and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders of Securities of such series under this Indenture; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each outstanding Security of each series affected thereby,

(1) extend the stated maturity of the principal of, or any installment or principal of or interest on, any such Security, or reduce the principal amount thereof or the rate of interest thereon or premium (if any), payable upon the redemption thereof, or reduce the obligation of the Company to pay principal amounts, or reduce the amount of the principal of a Discounted Security that would be due and payable upon a declaration of acceleration of the maturity or change the coin or currency in which, any such Security of such series or any principal, premium (if any), or interest thereon is payable or impair the right to institute suit for the enforcement of any such payment on or after the due date thereof (or, in the case of redemption, on or after the redemption date), or

(2) reduce the percentage in principal amount of the outstanding Securities of any series, the consent of whose Holders is required for any modifications or amendments to this Indenture or to the terms and conditions of that series of Securities, or to approve any supplemental indenture relating to such series, or the consent of whose Holders is required for any waiver with respect to such series (of compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences) provided for in this Indenture, or

(3) modify any of the provisions of this Section, Section 6.04 or Section 9.02, except to increase any such percentage or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Security affected thereby.

A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular previously created series of Securities, or which modifies the rights of the Holders of Securities of such previously created series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of such previously created series.

It shall not be necessary for any act of Holders under this
Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such act shall approve the substance thereof.

SECTION 9.03. Execution of Supplemental Indentures; Opinions.

In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture which affects the Trustee's own rights, duties or immunities under this Indenture or otherwise.

SECTION 9.04. Compliance with Trust Indenture Act.

Every amendment pursuant to Section 9.01 or 9.02 shall be set forth in a supplemental indenture that complies with the TIA as then in effect.

SECTION 9.05. Effect of Supplemental Indentures.

An amendment or waiver becomes effective in accordance with its terms and thereafter binds every Securityholder entitled to consent to it.

A consent to an amendment or waiver by a Holder of a Security is a continuing consent by the Holder and every subsequent Holder of a Security that evidences the same debt as the consenting Holder's Security. Any Holder or subsequent Holder may revoke the consent as to his Security if the Trustee receives notice of the revocation before the amendment or waiver becomes effective.

The Company may fix a record date for the determination of Holders of Registered Securities entitled to give a consent. The record date shall not be less than 10 nor more than 60 days prior to the first written solicitation of Securityholders.

Securities of any series authenticated and delivered after the execution of any supplemental indenture pursuant to this Article may, and shall if required by the Company, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Securities of any series so modified as to conform, in the opinion of the Trustee and the Company, to any such supplemental indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for Securities of such series.

SECTION 9.07. Trustee Protected.

The Trustee need not sign any supplemental indenture that adversely affects its rights. The Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Opinion of Counsel and an Officers' Certificate each stating that the execution of any amendment or supplement or waiver authorized pursuant to this Article is authorized or permitted by this Indenture, and that such amendment or supplement or waiver constitutes the legal, valid and binding obligation of the Company.
