If any interest payment date or date on which the principal of this bond is required to be paid is not a business day, then payment of principal, premium or interest need not be made on such date but may be made on the next succeeding business day with the same force and effect as if made on such interest payment date or date on which the principal of this bond is required to be paid and, in the case of timely payment thereof, no interest shall accrue for the period from and after such interest payment date or the date on which the principal of this bond is required to be paid.

of this series, in whole or in part, at a redemption price equal to the greater of (i) 100% of the principal amount of such bonds of this series being redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the bonds of this series being redeemed that would be due if such bonds matured on the Par Call Date (excluding the portion of any such accrued and unpaid interest to but excluding the date fixed for redemption), discounted to the date fixed for redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 15 basis points, plus, in each case, accrued and unpaid interest thereon to but excluding the date fixed for redemption.

Bonds of this series are not subject to a sinking fund.

This bond is transferable as prescribed in the Indenture by the registered owner hereof in person, or by his duly authorized attorney, at the office of the Trustee in the City of Chicago, Illinois, or at the option of the owner at the agency of the Company in the Borough of Manhattan, City and State of New York, or elsewhere if authorized by the Company, upon surrender and cancellation of this bond, and thereupon a new bond or bonds of the same series and of a like aggregate principal amount will be issued to the transferee in exchange therefor as provided in the Indenture, upon payment of taxes or other governmental charges, if any, that may be imposed in relation thereto.

No recourse shall be had for the payment of the principal of or the interest on this bond, or any part thereof, or of any claim based hereon or in respect hereof or of said Indenture, against any incorporator, or any past, present or future shareholder, officer or director of the Company or of any predecessor or successor corporation, either directly or through the Company, or through any such predecessor or successor corporation, or through any receiver or a trustee in bankruptcy, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released, as more fully provided in the Indenture.

This bond shall not be valid or become obligatory for any purpose unless and until the certificate of authentication hereon shall have been signed by or on behalf of The Bank of New York Mellon Trust Company, N.A.

Any such additional Series 2047 Bonds, together with the Series 2047 Bonds initially authenticated, shall constitute a single series for purposes of the Indenture and shall be limited to an aggregate principal amount of $1,200,000,000.

Thereupon the Trustee shall fix a Special Record Date for the payment of such defaulted interest which shall be not more than 15 nor less than 10 days prior to the date of the proposed payment and not less than 10 days after the

Notice of the proposed payment of such defaulted interest and the Special Record Date therefor having been mailed as aforesaid, such defaulted interest shall be paid to the persons in whose names the Series 2047 Bonds are registered on such Special Record Date and shall not be payable pursuant to the paragraph immediately following in this Section 2.01.

The Company may make payment of any defaulted interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Series 2047 Bonds may be listed, and upon such notice as may be required by such exchange, if, after notice is given by the Company to the Trustee of the proposed payment pursuant to this Section 2.01, such payment shall be deemed practicable by the Trustee.

The Series 2047 Bonds are not subject to a sinking fund.

The redemption price of the Series 2047 Bonds need not be specified in any temporary bond of said series if an appropriate reference be made in said temporary bond to the provision of this Section.

For purposes of Section 10.02 of the Indenture, the redemption price to be set forth in the notice of any redemption of the Series 2047 Bonds occurring prior to the Par Call Date may be the manner of calculation thereof. The Company shall give the Trustee notice of such redemption price promptly after the calculation thereof and the Trustee shall not be responsible for any such calculation.

SECTION 2.03. The registered owner of any Series 2047 Bond or Bonds, at his, her or its option, may surrender the same with other bonds of such series at the office of the Trustee in the City of Chicago, Illinois, or at the agency of the Company in the Borough of Manhattan, City and State of New York, or elsewhere if authorized by the Company, for cancellation, in exchange for other bonds of such series of higher or lower authorized denominations, but of the same aggregate principal amount, bearing interest from its date, and upon receipt of any payment required under the provisions of Section 2.04 hereof. Thereupon the Company shall execute and

deliver to the Trustee and the Trustee shall authenticate and deliver such other registered bonds to such registered owner at its office or at any other place specified as aforesaid.

Notwithstanding any other provisions of the Indenture to the contrary, the Company shall not be required to issue, transfer or exchange any Series 2047 Bond of a series during a period of ten (10) days next preceding any selection of Series 2047 Bonds of such series to be redeemed. The Company shall not be required to transfer or exchange any Series 2047 Bond called or being called for redemption in its entirety or to transfer or exchange the called portion of a Series 2047 Bond which has been called for partial redemption.

SECTION 2.04. No charge shall be made by the Company for any exchange or transfer of Series 2047 Bonds other than for taxes or other governmental charges, if any, that may be imposed in relation thereto.

SECTION 2.05. The Series 2047 Bonds shall be executed on behalf of the Company by its President or one of its Vice Presidents, and its corporate seal shall be thereunto affixed, or printed, lithographed or engraved thereon, in facsimile, and attested by the signature of its Secretary or one of its Assistant Secretaries. Any such signatures may be manual or facsimile signatures and may be imprinted or otherwise reproduced. In case any of the officers who shall have signed any Series 2047 Bonds or attested the seal thereon shall cease to be such officers of the Company before the Series 2047 Bonds so signed and sealed actually shall have been authenticated by the Trustee or delivered by the Company, such Series 2047 Bonds nevertheless may be issued, authenticated and delivered with the same force and effect as though the person or persons who signed such Series 2047 Bonds and attested the seal thereon had not ceased to be such officer or officers of the Company. Any Series 2047 Bond issuable hereunder may be signed or attested on behalf of the Company by such person as at the actual date of the execution of such Series 2047 Bond shall be the proper officer of the Company, although at the date of such Series 2047 Bond such person shall not have been an officer of the Company.

SECTION 2.06. (a)    Except as provided in subsections (c) and (g) of this Section 2.06, the registered holder of all of the Series 2047 Bonds shall be The Depository Trust Company (“DTC”) and such Series 2047 Bonds shall be registered in the name of Cede & Co., as nominee for DTC. Payment of principal of, premium, if any, and interest on any Series 2047 Bonds registered in the name of Cede & Co. shall be made by transfer of New York Federal or equivalent immediately available funds with respect to the Series 2047 Bonds to the account of Cede & Co. on each such payment date for the Series 2047 Bonds at the address indicated for Cede & Co. in the bond register kept by the Trustee.

(b)    The Series 2047 Bonds shall be initially issued in the form of one or more separate single authenticated fully registered certificates in the aggregate principal amount of all Series 2047 Bonds. Upon initial issuance, the ownership of such Series 2047 Bonds shall be registered in the bond register kept by the Trustee in the name of Cede & Co., as nominee of DTC. The Trustee and the Company may treat DTC (or its nominee) as the sole and exclusive registered holder of the Series 2047 Bonds registered in its name for the purposes of payment of the principal of, premium, if any, and interest on the Series 2047 Bonds and of giving any notice permitted or required to be given to holders under the Indenture, except as provided in subsection (g) below of this Section 2.06; and neither the Trustee nor the Company shall be affected by any

notice to the contrary. Neither the Trustee nor the Company shall have any responsibility or obligation to any of DTC’s participants (each, a “Participant”), any person claiming a beneficial ownership in the Series 2047 Bonds under or through DTC or any Participant (each, a “Beneficial Owner”) or any other person which is not shown on the bond register maintained by the Trustee as being a registered holder, with respect to (1) the accuracy of any records maintained by DTC or any Participant; (2) the payment by DTC or any Participant of any amount in respect of the principal of, premium, if any, or interest on the Series 2047 Bonds; (3) the delivery by DTC or any Participant of any notice to any Beneficial Owner which is permitted or required to be given to registered holders under the Indenture of the Series 2047 Bonds; (4) the selection of the Beneficial Owners to receive payment in the event of any partial redemption of the Series 2047 Bonds; or (5) any consent given or other action taken by DTC as bondholder. The Trustee shall pay all principal of, premium, if any, and interest on the Series 2047 Bonds registered in the name of Cede & Co. only to or “upon the order of” (as that term is used in the Uniform Commercial Code as adopted in Minnesota and New York) DTC, and all such payments shall be valid and effective to fully satisfy and discharge the Company’s obligations with respect to the principal of, premium, if any, and interest on such Series 2047 Bonds to the extent of the sum or sums so paid. Except as otherwise provided in subsections (c) and (g) below of this Section 2.06, no person other than DTC shall receive authenticated bond certificates evidencing the obligation of the Company to make payments of principal of and interest on the Series 2047 Bonds. Upon delivery by DTC to the Trustee of written notice to the effect that DTC has determined to substitute a new nominee in place of Cede & Co., and subject to the provisions of the Indenture with respect to transfers of bonds, the word “Cede & Co.” in this Supplemental Trust Indenture shall refer to such new nominee of DTC.

(c)    If the Company in its discretion determines that it is in the best interest of the Beneficial Owners that they be able to obtain bond certificates for the Series 2047 Bonds or there shall have occurred and be continuing a Completed Default with respect to the Series 2047 Bonds, the Company shall notify DTC and the Trustee, whereupon DTC will notify the Participants of the availability through DTC of bond certificates for Series 2047 Bonds. In such event, the Trustee shall issue, transfer and exchange bond certificates as requested by DTC in appropriate amounts pursuant to Article II of the Restated Indenture and Section 2.03 of this Supplemental Trust Indenture. The Company shall pay all costs in connection with the production of bond certificates if the Company makes such a determination under this Section 2.06(c). DTC may determine to discontinue providing its services with respect to a series of the Series 2047 Bonds at any time by giving written notice to the Company and the Trustee and discharging its responsibilities with respect thereto under applicable law. Under such circumstances (if there is no successor book-entry depository), the Company and the Trustee shall be obligated (at the sole cost and expense of the Company) to deliver bond certificates for the Series 2047 Bonds as described in this Supplemental Trust Indenture. If bond certificates are issued, the provisions of the Indenture shall apply to, among other things, the transfer and exchange of such certificates and the method of payment of principal of, premium, if any, and interest on such certificates. Whenever DTC requests the Company and the Trustee to do so, the Company will direct the Trustee (at the sole cost and expense of the Company) to cooperate with DTC in taking appropriate action after reasonable notice (i) to make available one or more separate certificates evidencing the Series 2047 Bonds to any Participant or (ii) to arrange for another book-entry depository to maintain custody of certificates evidencing the Series 2047 Bonds registered in the name of such depository or its nominee. Any successor book-entry

depository must be a clearing agency registered with the Securities and Exchange Commission pursuant to Section 17A of the Securities Exchange Act of 1934, as amended, and must enter into an agreement with the Company and the Trustee agreeing to act as the depository and clearing agency for the Series 2047 Bonds (except as provided in subsection (g) below of this Section 2.06). After such agreement has become effective, DTC shall present the Series 2047 Bonds for registration of transfer in accordance with Section 2.12 of the Restated Indenture, and the Trustee shall register them in the name of the successor book-entry depository or its nominee and all references thereafter to DTC shall be to such successor book-entry depository. If a successor book-entry depository has not accepted such position before the effective date of DTC’s termination of its services, the book-entry system shall automatically terminate and may not be reinstated without the consent of all registered holders of the Series 2047 Bonds.

(d)    Notwithstanding any other provision of this Supplemental Trust Indenture to the contrary, so long as any Series 2047 Bonds are registered in the name of Cede & Co., as nominee of DTC, all payments with respect to the principal of, premium, if any, and interest on such Series 2047 Bonds and all notices with respect to such Series 2047 Bonds shall be made and given, respectively, to DTC as provided in the blanket representation letter between DTC and the Company. The Trustee is hereby authorized and directed to comply with all terms of the representation letter to the extent applicable to the Trustee.

(e)    In connection with any notice or other communication to be provided pursuant to the Indenture for the Series 2047 Bonds by the Company or the Trustee with respect to any consent or other action to be taken by the registered holders of the Series 2047 Bonds, the Company or the Trustee, as the case may be, shall seek to establish a record date to the extent permitted by the Indenture for such consent or other action and give DTC notice of such record date not less than fifteen (15) calendar days in advance of such record date to the extent possible. Such notice to DTC shall be given only when DTC is the sole registered holder.

(f)    NEITHER THE COMPANY NOR THE TRUSTEE WILL HAVE ANY RESPONSIBILITY OR OBLIGATIONS TO THE PARTICIPANTS OR THE BENEFICIAL OWNERS WITH RESPECT TO (1) THE ACCURACY OF ANY RECORDS MAINTAINED BY DTC OR ANY PARTICIPANT; (2) THE PAYMENT BY DTC OR ANY PARTICIPANT OF ANY AMOUNT DUE TO ANY BENEFICIAL OWNER IN RESPECT OF THE PRINCIPAL OF, PREMIUM, IF ANY, OR INTEREST ON THE SERIES 2047 BONDS; (3) THE DELIVERY BY DTC OR ANY PARTICIPANT OF ANY NOTICE TO ANY BENEFICIAL OWNER WHICH IS REQUIRED OR PERMITTED UNDER THE TERMS OF THE INDENTURE TO BE GIVEN TO REGISTERED HOLDERS; (4) THE SELECTION OF THE BENEFICIAL OWNERS TO RECEIVE PAYMENT IN THE EVENT OF ANY PARTIAL REDEMPTION OF THE SERIES 2047 BONDS; OR (5) ANY CONSENT GIVEN OR OTHER ACTION TAKEN BY DTC AS A REGISTERED HOLDER.

SO LONG AS CEDE & CO. IS THE REGISTERED HOLDER OF THE SERIES 2047 BONDS AS NOMINEE OF DTC, REFERENCES HEREIN TO REGISTERED HOLDERS OF THE SERIES 2047 BONDS SHALL MEAN CEDE & CO. AND SHALL NOT MEAN THE BENEFICIAL OWNERS OF THE SERIES 2047 BONDS NOR THE PARTICIPANTS.

(g)    The Company, in its sole discretion, may terminate the services of DTC with respect to the Series 2047 Bonds if the Company determines that: (i) DTC (x) is unable to discharge its responsibilities with respect to Series 2047 Bonds or (y) at any time ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended; or (ii) there shall have occurred and be continuing a Completed Default with respect to either series of Series 2047 Bonds. The Company, in its sole discretion and subject to DTC’s procedures, may terminate the services of DTC with respect to Series 2047 Bonds if the Company determines that a continuation of the requirement that all of the outstanding Series 2047 Bonds be registered with the registration books kept by the Trustee in the name of Cede & Co., as nominee of DTC, is not in the best interest of the Beneficial Owners of the Series 2047 Bonds. After such event and if no substitute book-entry depository is appointed by the Company, the bond certificates for the Series 2047 Bonds will be delivered as described in the Indenture.

(h)    Upon the termination of the services of DTC with respect to the Series 2047 Bonds pursuant to subsections (c) or (g) of this Section 2.06 after which no substitute book-entry depository is appointed, the Series 2047 Bonds shall be registered in whatever name or names holders transferring or exchanging Series 2047 Bonds shall designate in accordance with the provisions of the Indenture.

SECTION 3.01. The Trustee shall, if requested in writing so to do by the Company, promptly appoint an agent or agents of the Trustee who shall have authority to authenticate registered Series 2047 Bonds in the name and on behalf of the Trustee. Such appointment by the Trustee shall be evidenced by a certificate of a vice-president of the Trustee delivered to the Company prior to the effectiveness of such appointment.

SECTION 3.02. (a)    Any such authenticating agent shall be acceptable to the Company and at all times shall be a corporation, trust company or banking association organized and doing business under the laws of the United States or of any State, shall be authorized under such laws to act as authenticating agent, shall have a combined capital and surplus of at least $10,000,000 and shall be subject to supervision or examination by Federal or State authority. If such corporation, trust company or banking association publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section 3.02 the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published.

(b)    Any corporation, trust company or banking association into which any authenticating agent may be merged or converted or with which it may be consolidated, or any corporation, trust company or banking association resulting from any merger, conversion or consolidation to which any authenticating agent shall be a party, or any corporation, trust company or banking association succeeding to the corporate agency business of any authenticating agent, shall continue to be the authenticating agent without the execution or filing of any paper or any further act on the part of the Trustee or the authenticating agent.

(c)    Any authenticating agent at any time may resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time, and upon written request of the Company to the Trustee shall, terminate the agency of any authenticating agent by giving written notice of termination to such authenticating agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time any authenticating agent shall cease to be eligible in accordance with the provisions of this Section 3.02, the Trustee, unless otherwise requested in writing by the Company, promptly shall appoint a successor authenticating agent, which shall be acceptable to the Company. Any successor authenticating agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers, duties and responsibilities of its predecessor hereunder, with like effect as if originally named. No successor authenticating agent shall be appointed unless eligible under the provisions of this Section 3.02.

(d)    The Company agrees to pay to any authenticating agent, appointed in accordance with the provisions of Section 3.01 and this Section 3.02, reasonable compensation for its services.

SECTION 3.03. If an appointment is made pursuant to this Article III, the registered Series 2047 Bonds shall have endorsed thereon, in addition to the Trustee’s Certificate, an alternate Trustee’s Certificate in the following form:

This bond is one of the bonds of the Series designated thereon, described in the within-mentioned Indenture.

SECTION 3.04. No provision of this Article III shall require the Trustee to have at any time more than one such authenticating agent for any one State or to appoint any such authenticating agent in the State in which the Trustee has its principal place of business.

SECTION 4.01. The name and address of the debtor and secured party are set forth below:

SECTION 4.06. The property covered by this Financing Statement also shall secure additional series of First Mortgage Bonds of the debtor which may be issued from time to time in the future in accordance with the provisions of the Indenture.

SECTION 5.01. The recitals of fact herein, except the recital that the Trustee has duly determined to execute this Supplemental Trust Indenture and be bound, insofar as it may lawfully so do, by the provisions hereof and in the bonds shall be taken as statements of the Company and shall not be construed as made by the Trustee. The Trustee makes no representations as to the value of any of the property subject to the lien of the Indenture, or any part thereof, or as to the title of the Company thereto, or as to the security afforded thereby and hereby, or as to the validity of this Supplemental Trust Indenture or of the bonds issued under the Indenture by virtue hereof (except the Trustee’s certificate) and the Trustee shall incur no responsibility in respect of such matters.

SECTION 5.02. This Supplemental Trust Indenture shall be construed in connection with and as a part of the Indenture.
