Unless an earlier Special Event Redemption has occurred, the Debt Securities shall mature and the principal amount thereof shall be due and payable together with all accrued and unpaid interest thereon on the Stated Maturity. The "Stated Maturity" shall mean February 16, 2009 or such later date falling on or prior to the tenth anniversary of the Reset Date determined by the Company on the Successful Remarketing Date (subject to agreement between the Company and the Remarketing Agent pursuant to Section 3(a) of the Remarketing Agreement with respect to the Remarketing Fee), it being understood that if there shall have been a Failed Remarketing, the Stated Maturity shall remain February 16, 2009. Any extension of the Stated Maturity in accordance with this Section 2.02 shall be effective on and after the Reset Date.

Payment of interest may be made, at the option of the Company, by check mailed to the address of the Persons entitled thereto or by wire transfer to an account designated by the Person entitled thereto. Notices and demands to or upon the Company in respect of the Debt Securities may be served at the office or agency of the Company in the Borough of Manhattan, City of New York. The Paying Office of the Trustee will initially be the agency of the Company for such payment, registration and registration of transfers and exchanges and service of notices and demands and the Company hereby appoints the Trustee as its agent for all such purposes; provided, however, that the Company reserves the right to change, by one or more Officer's Certificates, any such office agency and such agent. The Trustee will initially be the Transfer Agent, Security Registrar and the Paying Agent for the Debt Securities.

Section 2.05. Interest.

(a) The Debt Securities shall bear interest from and including the date of issuance at the per annum rate of 4.25% to (but excluding) the Reset Date or, if there shall have been a Failed Remarketing, to (but excluding) February 16, 2009, and from and after the Reset Date, at the Reset Rate until the principal hereof is paid or made available for payment. Interest shall be payable in arrears (i) quarterly on each February 16, May 16, August 16 and November 16, commencing August 16, 2004 (each, a "Quarterly Interest Payment Date"), to and including the Interest Payment Date next preceding the Reset Date, (ii) on the Reset Date (whether or not a Quarterly Interest Payment Date) and (iii) semi-annually on the Subsequent Interest Payment Dates (collectively, the "Interest Payment Dates"). Interest payments will include interest accrued from and including the immediately preceding Interest Payment Date or, in the case of the first Interest Payment Date, from and including June 14, 2004, to but excluding such Interest Payment Date. If the Reset Date is not a Quarterly Interest Payment Date, interest paid on the Reset Date to the Collateral Agent will be paid by the Collateral Agent to holders of Income PRIDES subject to the provisions of the Pledge Agreement and the Purchase Agreement on the Payment Date for the Income PRIDES next following the Reset Date.

(b) The amount of interest payable for any period will be computed on the basis of a 360-day year consisting of twelve 30-day months. In the event that any Interest Payment Date is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay); provided, however, that if such next succeeding Business Day is in the next succeeding calendar year, such payment will be made on the immediately preceding Business Day, in each case with the same force and effect as if made on the corresponding Interest Payment Date.

Section 2.06. Record Dates. Each installment of interest on a Debt Security shall be payable to the Person in whose name such Debt Security is registered at the close of business on the Regular Record Date for each Interest Payment Date, which, prior to the Reset Date, will be the February 1, May 1, August 1 or November 1 prior to the relevant Interest Payment Date and, after the Reset Date, will be as determined by the Company in connection with the establishment by the Company of the Subsequent Interest Payment Dates on the Successful Remarketing Date; provided that, interest payable on the Reset Date shall be payable to the Person in whose name the Debt Security is registered on the close of business on the Business Day prior to the Reset Date.

The Company agrees, and by acceptance of a beneficial ownership interest in the Debt Securities, each beneficial owner of Debt Securities will be deemed to have agreed (1) to treat the acquisition of an Income PRIDES as the acquisition of the 1/40undivided beneficial ownership interest in $1,000 principal amount of Debt Securities and the Purchase Contract constituting the Income PRIDES and (2) to treat the Debt Securities as indebtedness of the Company for United States federal, state, and local income and franchise tax purposes.

The Company may select a Three Day Remarketing Period during the Period for Early Remarketing by designating each of the three sequential Remarketing Dates to comprise such Three Day Remarketing Period, provided that no Remarketing Date shall occur earlier than the third Business Day prior to August 16, 2007 nor later than the ninth Business Day prior to the Purchase Contract Settlement Date.

(b) The Company will request, not later than seven nor more than 15 calendar days prior to each Remarketing Announcement Date, that the Depositary (or any successor or its nominee) notify the Depositary participants holding Debt Securities of the remarketing.

(c) On the fourth Business Day immediately preceding the first Remarketing Date of a Three Day Remarketing Period (each such date, a "Remarketing Announcement Date"), the Company will make an announcement regarding the proposed remarketing of the Debt Securities (the "Remarketing Announcement"). The Remarketing Announcement shall specify the following:

(i) that the Debt Securities may be remarketed on any and all of the fourth, fifth and sixth Business Days following such Remarketing Announcement Date;

(ii) (A) if the Remarketing Announcement relates to a remarketing to occur during the Period for Early Remarketing, that the Reset Date will be the third Business Day following the Remarketing Date on which the Debt Securities are successfully remarketed; or

(B) if the Remarketing Announcement relates to a remarketing to occur during the Final Three-Day Remarketing Period, that the Reset Date will be February 16, 2007 if there is a successful remarketing;

(iii) that the Reset Rate and Subsequent Interest Payment Dates for the Debt Securities will be established, and that the Stated Maturity of the Debt Securities may be extended by the Company, on the Remarketing Date and effective on and after the Reset Date;

(iv) (A) if the Remarketing Announcement relates to a remarketing to occur during the Period for Early Remarketing, that that the Reset Rate will equal the interest rate on the Debt Securities that will enable the Debt Securities to be remarketed at a price (the "Remarketing Value") equal to at least 100% of the sum of the Remarketing Treasury Portfolio Purchase Price and the Separate Debt Securities Purchase Price, plus the applicable Remarketing Fee; or

(B) if the Remarketing Announcement relates to a remarketing to occur during the Final Three-Day Remarketing Period, that that the Reset Rate will equal the interest rate on the Debt Securities that will enable the Debt Securities to be remarketed at a price (the "Contract Settlement Value") equal to at least 100% of their aggregate principal amount, plus the applicable Remarketing Fee; and

(v) the possible ranges of the Remarketing Fee, expressed as a percentage of the Treasury Portfolio Purchase Price and the Separate Debt Securities Purchase Price or as a percentage of the aggregate principal amount of the Debt Securities to be remarketed, as the case may be.

On the Business Day immediately following the Remarketing Announcement Date, the Company will cause the Remarketing Announcement to be published in an Authorized Newspaper. In the event that all of the remarketing attempts during a Three-Day Remarketing Period are unsuccessful, the Company will cause a notice of the unsuccessful remarketing attempt to be published in an Authorized Newspaper no later than the second Business Day following the last Remarketing Date of such Three-Day Remarketing Period (which notice, if the unsuccessful remarketing attempt shall occur during the Final Three-Day Remarketing Period, shall include the procedures that must be followed if a Holder of Debt Securities wishes to exercise its right to put such Debt Securities to the Company).

(d) On or prior to the second Business Day, but no earlier than the fifth Business Day, immediately preceding the first Remarketing Date of any Three-Day Remarketing Period, Holders of Separate Debt Securities may elect to have their Debt Securities remarketed in the same manner as Pledged Debt Securities by delivering their Separate Debt Securities, along with the notice of such election to the Custodial Agent specified in the Pledge Agreement. The Company shall cause the Custodial Agent to hold the Separate Debt Securities so delivered for remarketing in an account separate from the Collateral Account (as defined in the Pledge Agreement). Holders of Separate Debt Securities electing to have those Debt Securities remarketed will also have the right to withdraw the election on or prior to the second Business Day immediately preceding the first Remarketing Date of a Three-Day Remarketing Period.

(e) Unless and until there has been a successful remarketing on a Remarketing Date, on each Remarketing Date during a Three-Day Remarketing Period, the Company shall cause the Remarketing Agent to use its reasonable efforts to remarket the Debt Securities that the Collateral Agent and the Custodial Agent shall have notified the Remarketing Agent have been tendered for, or otherwise are to be included in, the remarketing, at a price per $1,000 principal amount of the Debt Securities such that the aggregate price for the aggregate principal amount of the Debt Securities being remarketed on that date will be at least (i) if the Reset Date is not the Purchase Contract Settlement Date, the Remarketing Value or (ii) if the Reset Date is the Purchase Contract Settlement Date, the Contract Settlement Value. The Remarketing Agent shall determine, in consultation with the Company, the reset interest rate that it believes will, when applied to the Debt Securities (with any extension of the Stated Maturity as determined by the Company pursuant to 2.05 of this First Supplemental Indenture taken into account), enable the aggregate principal amount of the Debt Securities being remarketed on such date to be sold at an aggregate price equal to at least (i) if the Reset Date is not the Purchase Contract Settlement Date, the Remarketing Value or (ii) if the Reset Date is the Purchase Contract Settlement Date, the Contract Settlement Value. The reset interest rate established on the Remarketing Date on which a successful remarketing occurs shall be the "Reset Rate." The Reset Rate shall be effective from and after the Reset Date. In no event will the Reset Rate exceed the rate of interest permitted by applicable law.

(f) In the event of a successful remarketing, on the Remarketing Date, the Remarketing Agent shall notify (i) the Collateral Agent, the Custodial Agent, the Purchase Contract Agent, the Company, the Trustee, the Depositary and the Clearing Agency of the Reset Rate determined in such remarketing, the Subsequent Interest Payment Dates and the related Regular Record Dates, any extension by the Company of the Stated Maturity of the Debt Securities and the aggregate principal amount of Debt Securities sold in such remarketing, (ii) each purchaser of the Reset Rate, the Subsequent Interest Payment Dates and the related Regular Record Dates, the Stated Maturity of the Debt Securities and the aggregate principal amount such purchaser is to purchase and (iii) each purchaser to give instructions to its Depositary participant to pay the purchase price on the Reset Date in same day funds against delivery of the Debt Securities purchased through the Depositary's normal procedures. In addition, the Company will request the Depositary to notify its participants, no later than the Business Day next succeeding the Remarketing Date, of the Reset Rate, the Subsequent Interest Payment Dates and related Regular Record Dates and any extension of the Stated Maturity of the Debt Securities.

(g) In accordance with the Depositary's normal procedures, on the Reset Date, the transactions described above with respect to each Debt Security tendered for purchase and sold in such remarketing shall be executed through the Depositary, and the accounts of the respective Depositary participants shall be debited and credited and such Debt Securities delivered by book entry as necessary to effect purchases and sales of such Debt Securities. The Depositary shall make payment in accordance with its normal procedures.

(h) In the event all remarketing attempts during a Three-Day Remarketing Period are unsuccessful, the Company shall cause the Remarketing Agent to return, no later than the Business Day immediately following the end of such Three-Day Remarketing Period, the Pledged Debt Securities to the Collateral Agent and the Separate Debt Securities delivered for remarketing to the Custodial Agent for return to the Holders. In addition, the Company shall cause the Custodial Agent to return such Separate Debt Securities to their Holders, no later than the Business Day immediately following such unsuccessful remarketing attempt.

(i) In no event shall the aggregate price for the Debt Securities in a remarketing be less than a price (the "Minimum Price") equal to (i) in the case of a remarketing during the Period for Early Remarketing, 100% of the sum of the Remarketing Treasury Portfolio Purchase Price and the Separate Debt Securities Purchase Price or (ii) in the case of a remarketing during the Final Three-Day Remarketing Period, 100% of the aggregate principal amount of the Debt Securities being remarketed. A remarketing attempt on any Remarketing Date will be deemed unsuccessful if the (i) Remarketing Agent is unable to remarket the Debt Securities for an aggregate price that is at least equal to the Minimum Price; or (ii) if a condition precedent to such remarketing is not fulfilled.

(j) The Remarketing Agent shall not have any obligation whatsoever to purchase any Debt Securities, whether a remarketing or otherwise, and shall in no way be obligated to provide funds to make payment upon tender of Debt Securities for remarketing or to otherwise expend or risk its own funds or incur or be exposed to financial liability in the performance of its respective duties under the Remarketing Agreement. The Company shall not be obligated in any case to provide funds to make payment upon tender of Debt Securities for remarketing.

This Debt Security is one of a duly authorized issue of securities of the Company (herein called the "Debt Securities"), issued and to be issued under an Indenture, dated as of June 1, 2004 (herein called the "Base Indenture"), and a First Supplemental Indenture, dated as of June 14, 2004 (herein called the "First Supplemental Indenture" and, together with the Base Indenture, and any amendments to either thereto, the "Indenture"), each between the Company and BNY Midwest Trust Company, as Trustee (herein called the "Trustee," which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Debt Securities and of the terms upon which the Debt Securities are, and are to be, authenticated and delivered.

Unless an earlier Special Event Redemption has occurred, this Debt Security shall mature and the principal amount thereof shall be due and payable together with all accrued and unpaid interest thereon on the Stated Maturity. The "Stated Maturity" shall mean February 16, 2009 or such later date falling on or prior to the tenth anniversary of the Reset Date determined by the Company on the Successful Remarketing Date (subject to agreement between the Company and the Remarketing Agent pursuant to Section 3(a) of the Remarketing Agreement with respect to the Remarketing Fee), it being understood that if there shall have been a Failed Remarketing, the Stated Maturity shall remain February 16, 2009. Any extension of the Stated Maturity in accordance with this shall be effective on and after the Reset Date.

If a Special Event shall occur and be continuing, the Company may, at its option, redeem the Debt Securities in whole (but not in part) at any time at a Redemption Price equal to the Redemption Amount plus accrued and unpaid interest thereon to the Special Event Redemption Date.

If this Debt Security is not a component of Income PRIDES, the Holder of this Debt Security may, on or prior to the second Business Day, but no earlier than the fifth Business Day, immediately preceding the first Remarketing Date of any Three-Day Remarketing Period, elect to have this Debt Security remarketed in the same manner as Pledged Debt Securities, by delivering this Debt Security, along with a notice of such election to BNY Midwest Trust Company, as Custodial Agent, for remarketing in accordance with the Pledge Agreement.

If a Failed Remarketing occurs, the Holder of this Debt Security shall have the right to require the Company to purchase this Debt Security on April 1, 2007 (the "Put Option Exercise Date"), upon at least three Business Days' prior notice, at a price equal to 100% of the principal amount of this Debt Security, plus accrued and unpaid interest, if any, thereon (the "Repayment Price").

In order for this Debt Security to be so repurchased, the Company must receive, on or prior to 5:00 p.m. New York City Time on the third Business Day immediately preceding the Put Option Exercise Date, at the then principal executive offices of the Company, this Debt Security with the form entitled "Option to Elect Repayment", on the reverse of or otherwise accompanying this Debt Security duly completed. Any such notice received by the Company shall be irrevocable. All questions as to the validity, eligibility (including time of receipt) and acceptance of the Debt Securities for repayment shall be determined by the Company, whose determination shall be final and binding. The payment of the Repayment Price in respect of the Debt Securities shall be made no later than 12:00 noon, New York City time, on the Put Option Exercise Date.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Debt Security upon compliance with certain conditions set forth in the Indenture.

If an Event of Default with respect to the Debt Securities shall occur and be continuing, the principal of the Debt Securities may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time outstanding of all series to be affected. The Indenture contains provisions permitting the Holders of a majority in aggregate principal amount of the Securities of all series then outstanding to waive compliance by the Company with certain provisions of the Indenture. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Debt Security shall be conclusive and binding upon such Holder and upon all future Holders of this Debt Security and of any Debt Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Debt Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Debt Security shall not have the right to institute any action, suit or proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of an Event of Default with respect to the Debt Securities and the continuance thereof, the Holders of a majority in the aggregate principal amount of the Securities of all series at the time outstanding in respect of which an Event of Default shall have occurred and be continuing, considered as one class, shall have made written request to the Trustee to institute such action, suit or proceeding in respect of such Event of Default as Trustee and offered the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee for 60 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding. The foregoing shall not apply to any suit instituted by the Holder of this Debt Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Debt Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Debt Security at the times, place and rate, and in the coin or currency, herein prescribed.

The Debt Securities are issuable only in registered form without coupons in denominations of $1,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Debt Securities are exchangeable for a like aggregate principal amount of Debt Securities and of like tenor and of authorized denominations, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange; provided, however, that the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with such exchange or transfer.

The Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Debt Security is registered as the absolute owner hereof for all purposes, whether or not this Debt Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.
