TITLE AND TERMS OF THE SECURITIES

SECTION 2.01. Title of the Securities; Stated Maturity. This Thirty-First Supplemental Indenture hereby establishes a series of Securities, which shall be known as the Company’s “2010 Series B 3.45% Senior Notes due 2020” (the “Notes”). For purposes of the Original Indenture, the Notes shall constitute a single series of Securities. The Stated Maturity on which the principal of the Notes shall be due and payable will be October 1, 2020.

SECTION 2.02. Certain Variations from the Original Indenture.

(a) The Notes shall have the benefit of the provisions of Article Four of the Original Indenture and shall have the benefit of, or be subject to, the other related provisions of the Original Indenture relating to the grant of security, including (for avoidance of doubt and not for purposes of limitation) the Granting Clause, the definitions of “Deliverable Mortgage Bonds,” “Deliverable Securities,” “Designated Mortgage Bonds,” “Grant,” “Mortgage,” “Mortgage Bonds,” “Mortgage Trustee,” “Previously Delivered Mortgage Bonds,” and “Trust Estate,” Section 301(20), Sections 301(a)(v), (ix), (x) and (xi), Sections 301(b)(ii) and (iii), Section 301(d), and Sections 601(4) and (8), subject, in each case, to the release provisions provided for in Section 4.02 herein.

(b) Section 503 of the Original Indenture shall apply to the Notes. The following shall be an additional condition to defeasance of the Notes under Section 503: the Company shall have delivered to the Trustee an Opinion of Counsel stating that (i) the Company has received from the Internal Revenue Service a letter ruling, or there has been published by the Internal Revenue

Service a Revenue Ruling, or (ii) since the date of execution of this Thirty-First Supplemental Indenture, there has been a change in the applicable U.S. Federal income tax law, in either case to the effect that, the Holders of such Outstanding Notes appertaining thereto will not recognize income, gain or loss for U.S. Federal income tax purposes as a result of such defeasance and will be subject to U.S. Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred, and, also, to the effect that, after the 123^rd day after the date of deposit, all money and other property as provided pursuant to Section 503 of the Original Indenture (including the proceeds thereof) deposited or caused to be deposited with the Trustee (or other qualifying trustee) pursuant to Section 503 of the Original Indenture to be held in trust will not be subject to any case or proceeding (whether voluntary or involuntary) in respect of the Company under any Federal or State bankruptcy, insolvency, reorganization or other similar law, or any decree or order for relief in respect of the Company issued in connection therewith.

SECTION 2.03. Amount and Denominations; DTC

(a) The aggregate principal amount of Notes that may be issued under this Thirty-First Supplemental Indenture is limited to $300,000,000 (except as provided in Section 301(2) of the Original Indenture); provided that the Company may, without the consent of the Holders of the Outstanding Notes, “reopen” the series of the Notes so as to increase the aggregate principal amount of the Notes Outstanding in compliance with the procedures set forth in the Original Indenture, including Section 301 and Section 303 thereof, so long as any such additional Notes have the same terms, conditions and CUSIP number (including, without limitation, rights to security and to receive accrued and unpaid interest) as the Notes then Outstanding. No additional Notes may be issued if an Event of Default has occurred with respect to the Notes. The Notes shall be issuable only in fully registered form and, as permitted by Section 301 and Section 302 of the Original Indenture, in denominations of $1,000 and integral multiples thereof. The Notes will initially be issued in global form (the “Global Securities”) under a book-entry system, registered in the name of The Depository Trust Company, as depository (“DTC”), or its nominee, which is hereby designated as “Depository” under the Indenture.

(b) If (i) the Depository notifies the Company that it is unwilling or unable to continue as Depository for such Global Security or if at any time such Depository ceases to be a clearing agency registered under the Securities Exchange Act of 1934, and, in either such case, the Company does not appoint a successor Depository within 90 days thereafter, or (ii) there shall have occurred and be continuing an Event of Default or an event which, with the giving of notice or lapse of time, or both, would constitute an Event of Default, certificates for the Notes will be registered and delivered to the Holders of record. Upon receipt of a withdrawal request from the Company, the Depository will notify its participants of the receipt of a withdrawal request from the Company, notifying participants that they may utilize the Depository’s withdrawal procedures if they wish to withdraw their securities from the Depository. To the extent that the book-entry system is discontinued, or if the Company fails to appoint a successor Depository, certificates for the Notes will be registered and delivered to the Holders of record.

SECTION 2.04. Certain Terms of the Notes.

(a) The Notes shall bear interest at the rate of 3.45% per annum on the principal amount thereof from the date of original issuance, or from the most recent Interest Payment Date to which interest has been paid or duly provided for, until the principal of the Notes becomes due and payable, and on any overdue principal and premium and (to the extent that payment of such interest is enforceable under applicable law) on any overdue installment of interest at the same rate per annum during such overdue period. Interest on the Notes will be payable semi-annually in arrears on April 1 and October 1 of each year (each such date, an “Interest Payment Date”), commencing April 1, 2011. The amount of interest payable for any period shall be computed on the basis of a 360-day year and twelve 30-day months.

(b) In the event that any Interest Payment Date, redemption date or other date of Maturity of the Notes is not a Business Day, then payment of the amount 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), in each case with the same force and effect as if made on such date. The interest installment so payable, and punctually paid or duly provided for, on any Interest Payment Date with respect to any Note will, as provided in the Original Indenture, be paid to the person in whose name the Note (or one or more Predecessor Securities, as defined in the Original Indenture) is registered at the close of business on the relevant record date for such interest installment, which shall be the fifteenth calendar day (whether or not a Business Day) prior to the relevant Interest Payment Date (the “Regular Record Date”). Any such interest installment not punctually paid or duly provided for shall forthwith cease to be payable to the registered Holders on such Regular Record Date, and may either be paid to the person in whose name the Note (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date to be fixed by the Trustee for the payment of such defaulted interest, notice whereof shall be given to the registered Holders of the Notes not less than ten days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Original Indenture. The principal of, and premium, if any, and the interest on the Notes shall be payable at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, the City of New York, in any coin or currency of the United States of America that at the time of payment is legal tender for payment of public and private debts; provided, however, that payment of interest may be made at the option of the Company by check mailed to the registered Holder at the close of business on the Regular Record Date at such address as shall appear in the Security Register. Notwithstanding the foregoing, so long as the Notes are Global Securities and are held in book-entry form through the facilities of the Depository, payments on the Notes will be made to the Depository or its nominee in accordance with arrangements then in effect between the Trustee and the Depository.

(c) The Notes are not subject to repayment at the option of the Holders thereof and are not subject to any sinking fund. As provided in the form of Notes attached hereto as Exhibit A, the Notes are subject to optional redemption, as a whole or in part, by the Company prior to Stated Maturity of the principal thereof on the terms set forth therein. Except as modified in the form of Notes, redemptions shall be effected in accordance with Article Twelve of the Original Indenture.

(d) The Notes shall have such other terms and provisions as are set forth in the form of Notes attached hereto as Exhibit A (which is incorporated by reference in and made a part of this Thirty-First Supplemental Indenture as if set forth in full at this place).

SECTION 2.06. Form of Notes. Attached hereto as Exhibit A is the form of the Notes.

SECURITY AND RELEASE PROVISIONS

SECTION 4.01. Security. Subject to Section 4.02 below, as provided in and pursuant to Article Four of the Original Indenture, the Notes will be secured as to payments of principal, interest and premium, if any, by a series of Mortgage Bonds (the “General and Refunding Mortgage Bonds, 2010 Series B”, the “Bonds,” the “Bonds of the related series” or the “related series of Bonds”) of the Company to be issued concurrently with the issuance of the Notes under and secured by a Mortgage and Deed of Trust, dated as of October 1, 1924, between the Company and The Bank of New York Mellon Trust Company, N.A., as successor trustee (the “Mortgage Trustee”), as amended and supplemented by various supplemental indentures, including the supplemental indenture, dated as of August 1, 2010, creating the Bonds (collectively, the “Mortgage”), pledged by the Company for the benefit of the Holders of the Notes to the Trustee under this Thirty-First Supplemental Indenture. The Bonds shall be issued in an aggregate principal amount equal to the aggregate principal amount of the Notes.

SECTION 4.02. Release. Until the Release Date and subject to Article Four of the Original Indenture, the Bonds of the related series issued and delivered to the Trustee shall serve as security for any and all obligations of the Company under all Notes from time to time Outstanding, including, but not limited to (1) the full and prompt payment of the principal and premium, if any, on the Notes when and as the same shall become due and payable in accordance with the terms and provisions of the Indenture or the Notes, either at the Stated Maturity thereof, upon acceleration of the maturity thereof, upon redemption, or otherwise, and (2) the full and prompt payment of any interest on the Notes when and as the same shall become due and payable in accordance with the terms and provisions of this Indenture or the Notes including, if and to the extent provided for in the Notes, interest on overdue installments of principal and (to the extent permitted by law) interest on overdue installments of interest.

Each supplemental indenture to the Mortgage pursuant to which any Bonds are issued shall contain a provision to the effect that any payment by the Company hereunder of principal of or premium or interest on Notes which shall have been authenticated and delivered in connection with the issuance and delivery to the Trustee of such Bonds (other than by the application of the proceeds of a payment in respect of such Bonds) shall to the extent thereof, be deemed to satisfy and discharge the obligation of the Company, if any, to make a payment of principal, premium or interest, as the case may be, in respect of such Bonds which is then due.

Notwithstanding anything in the Original Indenture to the contrary, and provided that Substitute Mortgage Bonds have been delivered in accordance with Section 4.03 hereof, from and after the Release Date, the obligation of the Company to make payment with respect to the principal of and premium, if any, and interest on the Bonds shall be deemed satisfied and discharged as provided in the supplemental indenture or indentures to the Mortgage creating such Bonds and the Bonds shall cease to secure in any manner Notes theretofore or subsequently issued; the Trustee shall thereupon surrender the Bonds to the Mortgage Trustee for cancellation and execute and deliver such proper instruments of release as may be required. From and after the Release Date, all Notes, whether theretofore or subsequently issued, shall be secured by Substitute Mortgage Bonds pursuant to Section 4.03 below, and any conditions to the issuance of Notes that refer or relate to Bonds or the Mortgage shall be inapplicable (except as such conditions shall be deemed to refer to Substitute Mortgage Bonds or a Substitute Mortgage pursuant to Section 4.03 below). From and after the Release Date, the Company shall not issue any additional Mortgage Bonds, including Pledged Bonds, under the Mortgage. Notice of the occurrence of the Release Date shall be given by the Trustee to the Holders of the Notes in the manner provided for in the Original Indenture not later than 30 days after the Company notifies the Trustee of the occurrence of the Release Date.

In connection with the establishment of the occurrence of the Release Date, the Trustee shall be entitled to receive, may presume the correctness of, and shall be fully protected in relying upon, an Officers’ Certificate designating the Release Date and stating that the conditions to the occurrence of the Release Date have been satisfied.

When the obligation of the Company to make payments with respect to the principal of, and premium, if any, and interest on all or any part of the Bonds shall be satisfied or deemed satisfied pursuant to the Original Indenture or pursuant to this Thirty-First Supplemental Indenture, the Trustee shall, upon written request of the Company, deliver to the Company without charge therefor all of the Bonds so satisfied or deemed satisfied, together with such appropriate instruments of transfer or release as may be reasonably requested by the Company. All Bonds delivered to the Company in accordance with this Section shall be delivered by the Company to the Mortgage Trustee for cancellation.

SECTION 4.03. Substitute Mortgage Bonds.

(a) The Company shall notify the Trustee not less than 90 days prior to the Release Date (or such shorter period as the Company and the Trustee may agree) that the Company will deliver to the Trustee on the Release Date Substitute Mortgage Bonds in an aggregate principal amount equal to the aggregate principal amount of Notes and any other Securities subject to the release provisions Outstanding on the Release Date, in trust for the benefit of the Holders from time to time of the Notes and any other Securities subject to the release provisions issued under the Original Indenture, as supplemented, as security for any and all obligations of the Company under the Notes and any other Securities subject to the release provisions, including but not limited to, (1) the full and prompt payment of the principal of and premium, if any, on the Notes and any other Securities subject to the release provisions when and as the same shall become due and payable in accordance with the terms and provisions of the Original Indenture, as supplemented, or the Notes or such other Securities subject to the release provisions, either at the stated maturity thereof, upon acceleration of the maturity thereof or upon redemption, and (2) the full and prompt payment of any interest on the Notes and any other Securities subject to the release provisions

when and as the same shall become due and payable in accordance with the terms and provisions of the Original Indenture, as supplemented, or the Notes or such other Securities subject to the release provisions.

(b) The Company shall deliver such Substitute Mortgage Bonds described in Section 4.03(a) in separate series and issues corresponding to the series and issues of Notes and other Securities subject to the release provisions Outstanding on or prior to the Release Date, each series or issue of Substitute Mortgage Bonds having the same stated rate or rates of interest (or interest calculated in the same manner), Interest Payment Dates, stated maturity date and redemption provisions, and in the same aggregate principal amount, as the related series or issue of Notes or other Securities subject to the release provisions outstanding on the Release Date; it being expressly understood that each such series of Substitute Mortgage Bonds shall be held by the Trustee for the benefit of the Holders of the corresponding series of Securities from time to time Outstanding subject to such terms and conditions relating to surrender to the Company, transfer restrictions, voting, application of payments of principal and interest and other matters as shall be set forth in an indenture supplemental hereto specifically providing for the delivery to the Trustee of such Substitute Mortgage Bonds. Such Substitute Mortgage Bonds shall be issued under and secured by a Substitute Mortgage (A) on which the Company shall be the obligor; and (B) which shall be qualified, or shall meet the requirements for qualification, under the Trust Indenture Act for the issuance of Substitute Mortgage Bonds.

(A) a supplemental indenture to the Original Indenture that provides among other things, that on the delivery of the Substitute Mortgage Bonds described in Section 4.03(b), the Company shall deliver to the Trustee in trust for the benefit of the Holders as described in Section 4.03(a) hereof, and the Trustee shall accept therefor, related series of Substitute Mortgage Bonds registered in the name of the Trustee and conforming to the requirements herein and therein specified;

(B) an Officer’s Certificate (1) stating that, to the knowledge of the signer, (a) no Event of Default has occurred and is continuing and (b) no event has occurred and is continuing which entitles the secured party under the Substitute Mortgage to accelerate the maturity of the indebtedness outstanding thereunder and (2) stating the aggregate principal amount of indebtedness issuable, and then proposed to be issued, under and secured by the lien of the Substitute Mortgage; and

(C) an Opinion of Counsel to the effect that (1) such Substitute Mortgage Bonds have been duly issued under such Substitute Mortgage and constitute valid obligations, entitled to the benefit of the lien of the Substitute Mortgage equally and ratably with all other indebtedness then outstanding secured by such lien and (2) such Substitute Mortgage is a lien on substantially all of the Company’s tangible properties (including real property) used in its electric utility business, and will constitute a lien on any such properties thereafter acquired; and there is no other lien securing indebtedness on substantially all of such properties prior to the lien of the Substitute Mortgage, except for the lien of the Mortgage.

(d) On or prior to the Release Date the Company shall provide an Officer’s Certificate stating that the Company has been advised in writing, within not more than 30 days prior to such substitution of the Substitute Mortgage Bonds for the Mortgage Bonds, by at least two credit rating agencies qualifying as “nationally recognized statistical rating organizations” (as defined by the Securities Exchange Act of 1934, as amended) then maintaining a securities rating on the Notes that the substitution of such Substitute Mortgage Bonds for the Mortgage Bonds will not result in a reduction of the securities rating assigned to the Notes by that credit rating agency immediately prior to the substitution or the suspension or withdrawal of its rating and the Company shall have provided the Trustee with written evidence of such advice.

(e) In the event that the Company cannot obtain assurance of at least two credit rating agencies as described in Section 4.03(d) above, the Company will take such actions as are necessary to cause the Release Date not to occur.

(f) Article Four and related provisions of the Original Indenture (except for any provisions relating to discharge of Bonds or amounts owing on Bonds on or after the Release Date) shall apply to Substitute Mortgage Bonds pledged to the Trustee hereunder and the provisions thereof shall be deemed to refer to the Substitute Mortgage and the Substitute Mortgage Bonds. Article Four and related provisions may be amended by the Company to have the Notes secured by Substitute Mortgage Bonds on and after the Release Date and make appropriate reference to the Substitute Mortgage and the Substitute Mortgage Bonds; provided, that the consent of Holders shall not be required in connection with such amendment.

On and after the Release Date, Section 601(8) of the Original Indenture shall no longer apply to the Notes.

(c) In addition, failure by the Company to deliver Substitute Mortgage Bonds in accordance with the provisions of Section 4.03 of this Supplemental Indenture on or prior to the Release Date shall be an “Event of Default” with respect to the Notes as contemplated by Section 601(9) of the Original Indenture.

ON THE RELEASE DATE AND SUBJECT TO DELIVERY OF SUBSTITUTE MORTGAGE BONDS IN ACCORDANCE WITH THE TERMS OF THE INDENTURE, THE NOTES SHALL CEASE TO BE SECURED BY SUCH MORTGAGE BONDS AND SHALL BE SECURED BY SUBSTITUTE MORTGAGE BONDS UNDER A SUBSTITUTE MORTGAGE.

This Note shall not be entitled to any benefit under the Indenture hereinafter referred to, be valid or become obligatory for any purpose until the Certificate of Authentication hereon shall have been signed by or on behalf of the Trustee.

Unless the Certificate of Authentication hereon has been executed by the Trustee or a duly appointed Authentication Agent referred to herein, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

This Note is one of a duly authorized series of Securities of the Company (herein sometimes referred to as the “Notes”), specified in the Indenture, all issued or to be issued in one or more series under and pursuant to a Collateral Trust Indenture dated as of June 30, 1993 (the “Original Indenture”) duly executed and delivered between the Company and The Bank of New York Mellon Trust Company, N.A., as successor Trustee (herein referred to as the “Trustee”), as supplemented through and including a Thirty-First Supplemental Indenture dated as of August 1, 2010 (together with the Original Indenture, the “Indenture”) between the Company and the Trustee, to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the registered Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered.

This Note is not subject to repayment at the option of the Holder hereof. Except as provided below, this Note is not redeemable by the Company prior to maturity and is not subject to any sinking fund.

This Note will be redeemable at the option of the Company, in whole at any time or in part from time to time (any such date of optional redemption, an “Optional Redemption Date,” which shall be a “Redemption Date” for purposes of the Indenture) at the redemption prices set forth below. At any time prior to July 1, 2020, the optional redemption price (which shall be a “Redemption Price” for purposes of the Indenture) will be equal to the greater of (i) 100% of the principal amount of this Note to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest of this Note to be redeemed (not including any portion of any payments of interest accrued to the Optional Redemption Date) until Stated Maturity, in each case discounted from their respective scheduled payment dates to such Optional Redemption Date on a semiannual basis (assuming a 360-day year consisting of 30-day months) at the Adjusted Treasury Rate (as defined below) plus 15 basis points, as determined by the Reference Treasury Dealer (as defined below), plus, in each case, accrued and unpaid interest thereon to the Redemption Date. At any time on or after July 1, 2020, the optional redemption price (which shall be a “Redemption Price” for purposes of the Indenture) will be equal to 100% of the principal amount of this Note to be redeemed plus accrued and unpaid interest thereon to the Redemption Date.

Notwithstanding the foregoing, installments of interest on this Note that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on

A-3

the Interest Payment Date to the registered Holders as of the close of business on the relevant Record Date.

“Adjusted Treasury Rate” means, with respect to any Optional Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, calculated on the third Business Day preceding such Optional Redemption Date assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Optional Redemption Date.

“Comparable Treasury Issue” means the United States Treasury security selected by the Reference Treasury Dealer as having a maturity comparable to the remaining term of this Note that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of this Note.

“Comparable Treasury Price” means, with respect to any Optional Redemption Date, (i) the average of the Reference Treasury Dealer Quotations for such Optional Redemption Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer than three such Reference Treasury Dealer Quotations, the average of all such quotations, or (iii) if only one Reference Treasury Dealer Quotation is received, such quotation.

“Reference Treasury Dealer” means: (i) each of Banc of America Securities LLC, Barclays Capital Inc., and a Primary Treasury Dealer (as defined below) selected by Scotia Capital (USA) Inc. (or their respective affiliates which are Primary Treasury Dealers), and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. government securities dealer in the United States (a “Primary Treasury Dealer”), the Company will substitute therefor another Primary Treasury Dealer; and (ii) any other Primary Treasury Dealer(s) selected by the Trustee after consultation with the Company.

“Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any Optional Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Optional Redemption Date.

Notice of any optional redemption will be mailed at least 30 days but not more than 60 days before the Optional Redemption Date to the Holder hereof at its registered address.

If notice has been provided in accordance with the Indenture and funds for the redemption of this Note called for redemption have been made available on the Redemption Date, this Note will cease to bear interest on the date fixed for redemption. Thereafter, the only right of the Holder hereof will be to receive payment of the Redemption Price.

The Company will notify the Trustee at least 60 days prior to giving notice of redemption (or such shorter period as is satisfactory to the Trustee) of the aggregate principal amount of Notes to be redeemed and the Redemption Date. If the Company elects to redeem all or a portion of the Notes, the redemption will be conditional upon receipt by the Paying Agent or the Trustee of monies sufficient to pay the Redemption Price. If the Notes are only partially redeemed by the

A-4

Company, the Trustee shall select which Notes are to be redeemed in a manner it deems fair and appropriate in accordance with the terms of the Indenture.

In the event of redemption of this Note in part only, a new Note or Notes of this series for the unredeemed portion hereof will be issued in the name of the registered Holder hereof upon the cancellation hereof.

In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of all of the Notes may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Note upon compliance by the Company with certain conditions set forth therein.

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the registered Holders of not less than a majority in aggregate principal amount of the outstanding Securities of each series affected at the time, as defined in the Indenture, to execute supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or of modifying in any manner the rights of the registered Holders of the Securities; provided, however, that no such supplemental indenture shall (i) extend the fixed maturity of any Securities of any series, or reduce the principal amount thereof, or reduce the rate of or extend the time of payment of interest thereon, or reduce any premium payable upon the redemption thereof, without the consent of the registered Holder of each Security so affected or (ii) reduce the aforesaid percentage of Securities, the registered Holders of which are required to consent to any such supplemental indenture, without the consent of the registered Holders of each Security then outstanding and affected thereby. The Indenture also contains provisions permitting (i) the registered Holders of at least 66 2/3% in aggregate principal amount of the Securities of all series at the time outstanding affected thereby, on behalf of the registered Holders of the Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and (ii) the registered Holders of a majority in aggregate principal amount of the Securities of all series at the time outstanding affected thereby, on behalf of the registered Holders of the Securities of such series, to waive certain past defaults under the Indenture and their consequences. Any such consent or waiver by the registered Holder of this Note (unless revoked as provided in the Indenture) shall be conclusive and binding upon such registered Holder and upon all future registered Holders and owners of this Note and of any Note issued in exchange hereof or in place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Note.

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

Prior to the Release Date, the Notes of this series shall be secured by a series of Mortgage Bonds (the “Related Series of Bonds”), delivered by the Company to the Trustee for the benefit of the Holders of the Notes. Reference is made to the Mortgage and the Indenture for a description of the rights of the Trustee as Holder of the Related Series of Bonds, the property

mortgaged and pledged under the Mortgage and the rights of the Company and of the Mortgage Trustee in respect thereof, the duties and immunities of the Mortgage Trustee and the terms and conditions upon which the Related Series of Bonds are secured and the circumstances under which additional Mortgage Bonds may be issued.

FROM AND AFTER SUCH TIME AS ALL BONDS, OTHER THAN (1) PLEDGED BONDS, INCLUDING THE RELATED SERIES OF BONDS, AND (2) MORTGAGE BONDS (EXCLUSIVE OF PLEDGED BONDS) WHICH DO NOT IN AGGREGATE PRINCIPAL AMOUNT EXCEED THE GREATER OF FIVE PERCENT (5%) OF NET TANGIBLE ASSETS OR FIVE PERCENT (5%) OF CAPITALIZATION, HAVE BEEN RETIRED THROUGH PAYMENT, REDEMPTION OR OTHERWISE (INCLUDING THOSE MORTGAGE BONDS THE PAYMENT FOR WHICH HAS BEEN PROVIDED FOR IN ACCORDANCE WITH THE MORTGAGE) AT, BEFORE OR AFTER THE MATURITY THEREOF, PROVIDED THAT NO DEFAULT OR EVENT OF DEFAULT HAS OCCURRED AND IS CONTINUING (THE “RELEASE DATE”) AND SUBJECT TO DELIVERY OF SUBSTITUTE MORTGAGE BONDS IN ACCORDANCE WITH THE TERMS OF THE INDENTURE, THE RELATED SERIES OF BONDS SHALL CEASE TO SECURE THE NOTES IN ANY MANNER AND THE NOTES SHALL INSTEAD BE SECURED BY SUBSTITUTE MORTGAGE BONDS DELIVERED TO THE TRUSTEE PURSUANT TO SECTION 4.03 OF THE THIRTY-FIRST SUPPLEMENTAL INDENTURE DATED AS OF AUGUST 1, 2010 TO THE INDENTURE DESCRIBED ABOVE.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable in the Security Register of the Company, upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the principal of and any interest on this Note are payable or at such other offices or agencies as the Company may designate, duly endorsed by or accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and the Security Registrar or any transfer agent duly executed by the registered Holder hereof or his or her attorney duly authorized in writing, and thereupon one or more new Notes of this series and of like tenor, of authorized denominations and for the same aggregate principal amount will be issued to the designated transferee or transferees. No service charge will be made for any such transfer, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in relation thereto.

Prior to due presentment for registration of transfer of this Note, the Company, the Trustee, any Paying Agent and any Note Registrar may deem and treat the registered Holder hereof as the absolute owner hereof (whether or not this Note shall be overdue and notwithstanding any notice of ownership or writing hereon made by anyone other than the Note Registrar) for the purpose of receiving payment of or on account of the principal hereof and interest due hereon and for all other purposes, and neither the Company nor the Trustee nor any Paying Agent nor any Security Registrar shall be affected by any notice to the contrary.

The Notes of this series are issuable only in fully registered form without coupons in denominations of $1,000 and any integral multiple thereof. This Global Security is exchangeable for Notes in definitive form only under certain limited circumstances set forth in the Indenture. As provided in the Indenture and subject to certain limitations therein set forth, Notes of this series are exchangeable for a like aggregate principal amount of Notes of this series of a different authorized denomination, as requested by the registered Holder surrendering the same.
