IT IS HEREBY CONVENATED, DECLARED AND AGREED by and between the Company and the Trustee, and its successor or successors in trust, as follows:

ARTICLE I

BONDS OF SERIES N

Section 1.01. There is hereby created and authorized two new series of bonds which shall be designated First Mortgage 4.625% Bonds, Series N-1, due May 1, 2013 and First Mortgage 4.625% Bonds, Series N-2 due May 1, 2013. The aggregate principal amount of bonds of Series N which may be executed by the Company and authenticated by the Trustee shall be limited to $40,000,000 (that is $40,000,000 for each of the bonds of Series N-1 and the bonds of Series N-2) (exclusive of bonds authenticated and delivered upon interdenominational or other exchanges and transfers pursuant to Section 3 of Article I hereof and Sections 9, 10, 11 and 12 of Article II of the Original Indenture and delivered pursuant to Section I of Article VI of the Original Indenture as the same may relate to fully registered bonds including, without limitation, any exchange of bonds of Series N-1 for bonds of Series N-2); provided, however, that no more than $40,000,000 aggregate principal amount of bonds of Series N shall be outstanding at any given time. All bonds of Series N shall be registered bonds without coupons and shall be dated as provided in Section 1 of Article II of the Indenture and so long as there is no existing default in the payment of interest upon the bonds of Series N, any bond of Series N issued after the close of business on any Record Date, as hereinafter defined, with respect to any interest payment date

(May 1 or November 1, as the case may be) and prior to such interest payment date shall be dated as of such interest payment date; provided, however, that if and to the extent that the Company shall default in the payment of interest due on such interest payment date, then any such bond of Series N shall bear interest from the May 1 or November 1, as the case may be, being the interest payment date for bonds of Series N to which interest has previously been paid or made available for payment on the outstanding bonds of said series, or if the Company shall default in the payment of interest on the first interest payment date for bonds of Series N, then from the date of the commencement of the first interest period of such bonds of Series N-1, which date shall be the date of initial issuance of the bonds of Series N-1.

All bonds of Series N shall bear interest from the date thereof, payable at or before 9:00 o’clock a.m. Chicago time on the first day of May and the first day of November in each year, commencing November 1, 2003, until the principal thereof shall have become due and payable, at the rate of 4.625% per annum, and on any overdue principal and (to the extent that payment of such interest is enforceable under the applicable law) on any overdue installment of interest at the same rate per annum, and shall be payable both as to principal and interest, and as to premium, if any, in coin or currency of the United States of America which at the time of payment is legal tender for the payment of public and private debts, at the office or agency of the Trustee in St. Xxxx, Minnesota provided, however, that if a Registration Default (as defined in the Registration Rights Agreement by and among the Company and the Initial Purchasers (as defined therein), dated as of April 29, 2003 (the “Registration Rights Agreement”)) occurs, additional interest will accrue on the bonds of Series N at a rate of 0.25% per annum (increasing by an additional 0.25% per annum after each consecutive 90-day period that occurs, after the date on which such Registration Default occurs up to a maximum additional interest rate of 1.00% per annum) from and including the date on which any such Registration Default shall occur to but excluding the date on which all Registration Defaults have been cured.

So long as there is no existing default in the payment of interest on the bonds of Series N, the interest payable on any interest payment date shall be paid to the person in whose name any bond of Series N is registered at the close of business on the Record Date with respect to such interest payment date, and such person shall be entitled to receive the interest payable on such interest payment date notwithstanding the cancellation of any such bond of Series N on any exchange or transfer of registration thereof subsequent to the Record Date and prior to such interest payment date, except as and to the extent the Company shall default in the payment of interest due on such interest payment date, in which event such defaulted interest shall be paid to the person in whose name each bond of Series N is registered on the close of business on a subsequent Record Date, which shall not be less than five (5) days prior to the date of payment of such defaulted interest, established by notice given by mail by or on behalf of the Company to the persons in whose names such bonds of Series N are registered and to the Trustee not less than ten (10) days preceding such subsequent Record Date.

As used in this Section 1.01, the term “Record Date” means, with respect to any interest payment date (May 1, or November 1, as the case may be), the fifteenth day of April or the fifteenth day of October, as the case may be, next preceding such interest payment date, or, if such fifteenth day of April or fifteenth day of October is not a Business Day, the Business Day

next preceding such fifteenth day of April or fifteenth day of October, or with respect to the payment of defaulted interest, the date established by the Company as hereinabove provided.

As used in this Section 1.01, the term “default in the payment of interest” means failure to pay interest on the applicable interest payment date disregarding any period of grace permitted by the Indenture, as amended and supplemented.

Section 1.02. Bonds of Series N may be issued only as registered bonds without coupons (hereinafter sometimes referred to as “registered bonds”), and they shall be substantially in the form hereinbefore recited. They shall be issuable in denominations which shall be multiples of $1,000 and any integral multiple thereof and the execution by the Company of any bond of Series N shall evidence conclusively the due authorization of the denomination of such bond. Each registered bond of Series N shall be dated as of the date of the interest payment date on which interest was paid on other bonds of said Series next preceding the date of issue of such registered bond, except that (i) so long as there is no existing default in the payment of interest upon the bonds of Series N, any bond of Series N issued after the close of business on any record date with respect to any interest payment date and prior to such interest payment date, shall be dated as of such interest payment date, and (ii) any bond of Series N issued on an interest payment date on which interest on other bonds of Series N was paid shall be dated as of the date of issue and (iii) any bond of Series N issued before the initial interest payment date, shall be dated the date of commencement of the first interest period for the bonds of Series N, unless (i) above is applicable.

The registered owner of any bond of Series N dated as of an interest payment date as provided in (i) above shall, if the Company shall default in the payment of interest due on such interest payment date and such default shall be continuing, be entitled to exchange such bond for a bond or bonds of Series N of the same aggregate principal amount dated as of the interest payment date next preceding the interest payment date first mentioned in this sentence, or, if the Company shall default in the payment of interest on the first interest payment date for bonds of Series N, such owner shall be entitled to exchange such bond for a bond or bonds of Series N of the same aggregate principal amount dated the date of initial issuance of the bonds of Series N-1. If the Trustee shall have knowledge at any time that any registered owner of a bond of Series N shall be entitled by the provision of the next preceding sentence to exchange such bond, the Trustee shall within thirty (30) days mail to such owner at the address of such owner appearing upon the registry book, a notice informing such owner that such owner has such right of exchange.

Section 1.03. The bonds of Series N are subject to mandatory redemption in whole, upon the notice and in the manner and with the effect provided in the Indenture, at a redemption price equal to 100% of the principal amount thereof, plus accrued interest, if any, to the redemption date in the event that all or substantially all of the mortgaged property shall be sold or taken by the power of eminent domain or otherwise.

Bonds of Series N shall be redeemable upon the notice provided for in Section 1.04 of this Article I.

Section 1.04. If bonds of Series N are to be redeemed as provided in Section 1.03 of this Article I, notice of redemption shall be mailed by or on behalf of the Company, postage prepaid, at least thirty (30) days and not more than sixty (60) days prior to such date of redemption, to the registered owners of all bonds of Series N to be so redeemed, at their respective addresses appearing upon the registry book. Any notice which is mailed as herein provided shall be conclusively presumed to have been properly and sufficiently given on the date of such mailing, whether or not the holder receives the notice. In any case, failure to give due notice by mail, or any defect in the notice, to the registered owners of any bonds of Series N designated for redemption as a whole or in part, shall not affect the validity of the proceedings for the redemption of any other bond of Series N. In case of any redemption of bonds of Series N by the Trustee pursuant to the provisions of the Indenture or any indenture supplemental thereto, notice of redemption shall be given in a similar manner by the Trustee.

Except as provided above, the provisions of Article VI of the Indenture shall apply to any redemption of the bonds of Series N under Section 1.03 hereof.

Section 1.05. Upon the execution and delivery of this Fourteenth Supplemental Indenture and upon compliance with the applicable provisions of the Indenture, as supplemented by this Fourteenth Supplemental Indenture, the Company shall execute and deliver to the Trustee and the Trustee shall authenticate and deliver to or upon the written order of the President, or an Executive Vice President or a Vice President of the Company, bonds of Series N in an aggregate principal amount of $40,000,000 (that is, $40,000,000 for each of the bonds of Series N-1 and bonds of Series N-2, provided, that no more than $40,000,000 aggregate principal amount of bonds of Series N shall be outstanding at any given time). All bonds of Series N shall be executed on behalf of the Company by the manual or facsimile signature of its President, or an Executive Vice President or a Vice President of the Company and its corporate seal shall be impressed or imprinted and attested by its Secretary or one of its Assistant Secretaries, manually or in facsimile, and be authenticated by the manual execution by the Trustee of the certificate endorsed on said bonds of Series N.

Each Global Bond will represent such of the outstanding bonds as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding bonds of Series N from time to time endorsed thereon and that the aggregate principal amount of outstanding bonds represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Bond to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding bonds of Series N represented thereby will be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the holder thereof as required by Section 1.10 of Article I hereof.

(b) Temporary Global Bonds. Bonds of Series N offered and sold in reliance on Regulation S will be issued initially in the form of the Regulation S Temporary Global Bond, which will be deposited on behalf of the purchasers of the bonds represented thereby with the Trustee, at its St. Xxxx, Minnesota office, as custodian for the Depositary, and registered in the name of the Depositary or the nominee of the Depositary for the accounts of designated agents holding on behalf of Euroclear or Clearstream Bank, duly executed by the Company and authenticated by the Trustee as hereinafter provided. The Restricted Period will be terminated upon the receipt by the Trustee of:

(2) an Officers’ Certificate from the Company.

Following the termination of the Restricted Period, beneficial interests in the Regulation S Temporary Global Bond will be exchanged for beneficial interests in Regulation S Permanent Global Bonds pursuant to the Applicable Procedures. Simultaneously with the authentication of Regulation S Permanent Global Bonds, the Trustee will cancel the Regulation S Temporary Global Bond. The aggregate principal amount of the Regulation S Temporary Global Bond and the Regulation S Permanent Global Bonds may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary or its nominee, as the case may be, in connection with transfers of interest as hereinafter provided.

Anything in Section 1 of this Article XVI to the contrary notwithstanding, with the consent of the holders and registered owners of not less than sixty per centum (60%) in aggregate principal amount of all the bonds then outstanding (determined as provided in Section 2 of Article XVII of this Indenture) or their attorneys-in-fact duly authorized, or, if the rights of the holders of one or more, but not all, series then outstanding are affected, the consent of the holders and registered owners of not less than sixty per centum (60%) in aggregate principal amount of all the bonds then outstanding (determined as provided in Section 2 of Article XVII of this Indenture) of all affected series, taken together, and of any other series, the Company, when authorized by resolution of its Board of Directors, and the Trustee from time to time and at any time, subject to the restrictions in this Indenture contained, 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 any supplemental indenture or modifying the rights and obligations of the Company and the rights of the holders of any of the bonds and coupons; provided, however, that no such supplemental indenture shall (1) extend the maturity of any of the bonds or reduce the rate or extend the time of payment of interest thereon, or reduce the amount of the principal thereof, or reduce any premium payable on the redemption thereof or change the coin or currency in which any bond or interest thereon is payable, without the consent of the holder or registered owner of each bond so affected, or (2) permit the creation of any lien, not otherwise permitted, prior to or on a parity with the lien of the Indenture, without the consent of the holders and registered owners of all the bonds then outstanding, or (3) reduce the aforesaid percentage of the aggregate principal amount of bonds the holders and registered owners of which are required to approve any such supplemental indenture, without the consent of the holders of all the bonds then outstanding. For the purposes of this Section 4, bonds shall be deemed to be affected by a supplemental indenture if, in the opinion of the Trustee, such supplemental indenture would adversely affect or diminish the rights of holders thereof against the Company or against its property.

Upon the written request of the Company, accompanied by a resolution of its Board of Directors authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence

of the consent of bondholders as aforesaid (the instrument or instruments evidencing such consent to be dated within one year of such request), the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture. The Trustee shall be entitled to receive and, subject to Section 1 of Article XV hereof, may rely upon, an opinion of counsel as conclusive evidence that any such supplemental indenture is authorized or permitted by the provisions of this Section 4.

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

The Company and the Trustee, if they so elect, and either before or after such 60% or greater consent has been obtained, may require the holder or registered owner of any bond consenting to the execution of any such supplemental indenture to submit his bond to the Trustee or to such bank, banker or trust company as may be designated by the Trustee for the purpose, for the notation thereon of the fact that the holder or registered owner of such bond has consented to the execution of such supplemental indenture, and in such case such notation, in form satisfactory to the Trustee, shall be made upon all bonds so submitted, and such bonds bearing such notation shall forthwith be returned to the persons entitled thereto. All subsequent holders and registered owners of bonds bearing such notation shall be deemed to have consented to the execution of such supplemental indenture, and consent, once given or deemed to be given, may not be withdrawn.

Prior to the execution by the Company and the Trustee of any supplemental indenture pursuant to the provisions of this Section 4, the Company shall publish a notice, setting forth in general terms the substance of such supplemental indenture, at least once in one daily newspaper of general circulation in each city in which the principal of any of the bonds shall be payable, or, if all bonds outstanding shall be registered bonds without coupons or coupon bonds registered as to principal, such notice shall be sufficiently given if mailed, first class, postage prepaid, and registered if the Company so elects, to each registered holder of bonds at the last address of such holder appearing on the registry books, such publication or mailing, as the case may be, to be made not less than thirty (30) days prior to such execution. Any failure of the Company to give such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture.”

In case of certain events of default specified in the Indenture, the principal of all bonds issued and outstanding thereunder may be declared or may become due and payable in the manner and with the effect provided in the Indenture.

No recourse shall be had for the payment of the principal of or interest on this Bond, or for any claim based hereon, or otherwise in respect hereof or of the Indenture, to or against any incorporator, stockholder, director or officer, past, present or future, of the Company, either directly or through the Company, under any constitution or statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability of incorporators, stockholders, directors and officers being released by the holder hereof by the acceptance of this Bond, and being likewise waived and released by the terms of the Indenture.

This Bond is transferable by the registered holder hereof in person or by a duly authorized attorney at the office or agency of the Company in the City of Chicago, State of Illinois, upon surrender and cancellation of this Bond, and thereupon a new registered bond or bonds, without coupons, of the same series and for the same aggregate principal amount will be issued to the transferee in exchange herefor.
