“DTC” means The Depository Trust Company.

“Electronic Means” means the following communications methods: e-mail, facsimile transmission, secure electronic transmission containing applicable authorization codes, passwords and/or authentication keys issued by the Trustee, or another method or system specified by the Trustee as available for use in connection with its services hereunder.

“Original Issue Date” means June 8, 2022.

“Par Call Date” means (1) with respect to the 2027 Bonds, the 2027 Bonds Par Call Date, and (2) with respect to the 2032 Bonds, the 2032 Bonds Par Call Date.

“Redemption Price” means (1) with respect to the 2025 Bonds, the price at which the 2025 Bonds may be redeemed pursuant to Section 208(a) hereto, (2) with respect to the 2027 Bonds, the price at which the 2027 Bonds may be redeemed pursuant to Section 308(a) or Section 308(b) hereto, as applicable or (3) with respect to the 2032 Bonds, the price at which the 2032 Bonds may be redeemed pursuant to Section 408(a) or Section 408(b) hereto, as applicable.

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities—Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Stated Maturity of the 2025 Bonds or the applicable Par Call Date of the 2027 Bonds and the 2032 Bonds (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the Stated Maturity of the 2025 Bonds or the applicable Par Call Date for the 2027 Bonds and the 2032 Bonds on a straight-line basis (using the actual number of days) using such yields and rounding the result to

2

three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third Business Day preceding the Redemption Date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Stated Maturity of the 2025 Bonds or the applicable Par Call Date for the 2027 Bonds and the 2032 Bonds. If there is no United States Treasury security maturing on the Stated Maturity of the 2025 Bonds or the applicable Par Call Date for the 2027 Bonds and the 2032 Bonds but there are two or more United States Treasury securities with a maturity date equally distant from the Stated Maturity of the 2025 Bonds or the applicable Par Call Date for the 2027 Bonds and the 2032 Bonds, one with a maturity date preceding such Stated Maturity or Par Call Date and one with a maturity date following such Stated Maturity or Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding such Stated Maturity or Par Call Date. If there are two or more United States Treasury securities maturing on the Stated Maturity of the 2025 Bonds or the applicable Par Call Date for the 2027 Bonds and the 2032 Bonds or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

[FORM OF REVERSE OF 4.950% FIRST MORTGAGE BOND DUE 2025]

This 4.950% First Mortgage Bond due 2025 is one of a duly authorized issue of Bonds of the Company (the “Bonds”), issued and issuable in one or more series under and equally secured by an Indenture of Mortgage, dated as of June 19, 2020 (such Mortgage Indenture as originally executed and delivered and as supplemented or amended from time to time thereafter, together with any constituent instruments establishing the terms of particular Bonds, being herein called the “Mortgage Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Mortgage Indenture), and reference is hereby made to the Mortgage Indenture for a description of the property mortgaged, pledged and held in trust, the nature and extent of the security and the respective rights, limitations of rights, duties and immunities of the Company, the Trustee and the Holders of Bonds thereunder and of the terms and conditions upon which Bonds are, and are to be, authenticated and delivered. The acceptance of this Bond shall be deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Mortgage Indenture.

The Company shall not be required to make any mandatory redemption or sinking fund payments with respect to the Bonds of this series.

Subject to the terms and conditions of the Mortgage Indenture, prior to the Maturity Date, the Company may redeem the Bonds of this series at its option (“Optional Redemption”), in whole or in part, at any time and from time to time at a Redemption Price (expressed as a percentage of the principal amount and rounded to three decimal places) equal to the greater of: (1)(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 35 basis points, less (b) interest accrued to the Redemption Date; and (2) 100% of the principal amount of the Bonds of this series to be redeemed, plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

For purposes of determining the Redemption Price, the following terms have the following meanings:

“Maturity Date” means June 8, 2025.

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities—Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant

A-6

maturity on H.15 exactly equal to the period from the Redemption Date to the Maturity Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the Maturity Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third Business Day preceding the Redemption Date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Maturity Date. If there is no United States Treasury security maturing on the Maturity Date but there are two or more United States Treasury securities with a maturity date equally distant from the applicable Maturity Date, one with a maturity date preceding the Maturity Date and one with a maturity date following the Maturity Date, the Company shall select the United States Treasury security with a maturity date preceding the Maturity Date. If there are two or more United States Treasury securities maturing on the Maturity Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

Interest installments whose Stated Maturity is on or prior to such Redemption Date will be payable to Holders of such Bonds of this series, or one or more Predecessor Bonds, of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Mortgage Indenture.

In the case of an Optional Redemption, notice of redemption will be sent not less than 10 days nor more than 60 days prior to the Redemption Date to each Holder of Bonds of this series to be redeemed. If money sufficient to pay the Redemption Price of all Bonds of this series (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent or the Trustee on or prior to the Redemption Date, from and after such Redemption Date such Bonds of this series or portions thereof shall cease to bear interest. The Bonds of this series in denominations larger than $2,000 in principal amount may be redeemed in part but only in integral multiples of $1,000.

A-7

In the case of a partial redemption, selection of the Bonds of this series for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. No Bonds of this series of a principal amount of $2,000 or less will be redeemed in part. If any Bond of this series is to be redeemed in part only, the notice of redemption that relates to the Bond of this series will state the portion of the principal amount of the Bond of this series to be redeemed. A new Bond of this series in a principal amount equal to the unredeemed portion of the Bond of this series will be issued in the name of the Holder of the Bond of this series upon surrender for cancellation of the original Bond of this series. For so long as the Bonds of this series are held by DTC (or another Depositary), the redemption of the Bonds of this series shall be done in accordance with the policies and procedures of the Depositary.

As provided in the Mortgage Indenture and subject to certain limitations therein set forth, this Bond or any portion of the principal amount hereof will be deemed to have been paid for all purposes of the Mortgage Indenture and to be no longer Outstanding thereunder, and the Company’s entire indebtedness in respect thereof will be satisfied and discharged, if there has been irrevocably deposited with the Trustee or any Paying Agent (other than the Company), in trust, money in an amount which will be sufficient and/or Eligible Obligations, the principal of and interest on which when due, without regard to any reinvestment thereof, will provide moneys which, together with money, if any, deposited with or held by the Trustee or such Paying Agent, will be sufficient to pay when due the principal of and premium, if any, and interest on this Bond when due.

If an Event of Default shall occur and be continuing as provided in the Mortgage Indenture, the Trustee or the Holders of not less than 25% in aggregate principal amount of Bonds then Outstanding, considered as one class, may declare the principal amount of all Bonds then Outstanding to be due and payable immediately by notice in writing to the Company (and to the Trustee if given by Holders); provided, however, that with respect to certain Events of Default relating to bankruptcy, insolvency and similar events, the principal amount of all Bonds then Outstanding shall be due and payable immediately without further action by the Trustee or the Holders.

The Mortgage Indenture permits, with certain exceptions as therein provided, the Company and the Trustee to enter into one or more supplemental indentures for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, the Mortgage Indenture with the consent of the Holders of not less than a majority in aggregate principal amount of the Bonds at the time Outstanding, considered as one class; provided, however, that if there shall be Bonds of more than one series Outstanding under the Mortgage Indenture and if a proposed supplemental indenture shall directly affect the rights of the Holders of Bonds of one or more, but less than all, of such series, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Bonds of all series so directly affected, considered as one class, shall be required; and provided, further, that if the Bonds of any series shall have been issued in more than one Tranche and if a proposed supplemental indenture shall directly affect the rights of the Holders of Bonds of one or more, but less than all, of such Tranches, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Bonds of all Tranches so directly affected, considered as one class, shall be required; and provided, further, that the Mortgage Indenture permits the Company and the Trustee to enter into one or more supplemental indentures for certain purposes without the consent of any Holders of Bonds. The Mortgage

A-8

Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of Bonds, on behalf of the Holders of all such Bonds, to waive certain past defaults under the Mortgage Indenture and their consequences. Any such consent or waiver by the Holder of this Bond shall be conclusive and binding upon such Holder and upon all future Holders of this Bond and of any Bond 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 Bond.

As provided in and subject to the provisions of the Mortgage Indenture, the Holder of this Bond shall not have the right to institute any proceeding with respect to the Mortgage 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 a continuing Event of Default, the Holders of at least 25% in aggregate principal amount of the Bonds at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of at least a majority in aggregate principal amount of Bonds at the time Outstanding a direction inconsistent with such written request, and shall have failed to institute any such proceeding for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Bond 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 Mortgage Indenture and no provision of this Bond or of the Mortgage 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 Bond at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Mortgage Indenture and subject to certain limitations therein set forth, the transfer of this Bond is registrable in the Bond Register, upon surrender of this Bond for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Bond are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company, the Trustee or the Bond Registrar, as the case may be, duly executed by the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Bonds 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.

The Bonds of this series are issuable only in registered form without coupons in denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Mortgage Indenture and subject to certain limitations therein set forth, Bonds of this series are exchangeable for a like aggregate principal amount of Bonds of this series and of like tenor of a different authorized denomination, as requested by the Holders surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

A-9

The Company shall not be required to execute or to provide for the registration of the transfer of or the exchange of (A) any Bond of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers (or with respect to Global Bonds, CUSIP numbers) of the Bonds of this series called for redemption, or (B) any Bond of this series selected for redemption in whole or in part, except the unredeemed portion of any Bond of this series being redeemed in part.

Prior to due presentment of this Bond for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Bond is registered as the owner hereof for all purposes, whether or not this Bond is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

This Bond shall be governed by, and construed and enforced in accordance with, the laws of the State of New York without regard to the principles of conflicts of laws thereunder, except to the extent that the Trust Indenture Act shall be applicable.

As provided in the Mortgage Indenture, no recourse shall be had for the payment of the principal of, premium, if any, or interest with respect to this Bond, or any part thereof, or for any claim based hereon or otherwise in respect hereof, or of the indebtedness represented hereby, or upon any obligation, covenant or agreement under the Mortgage Indenture, against any incorporator, shareholder, officer or director, as such, past, present or future, of the Company or of any predecessor or successor corporation (either directly or through the Company or a predecessor or successor corporation), whether by virtue of any constitutional provision, statute or rule of law or by the enforcement of any assessment or penalty or otherwise; it being expressly agreed and understood that the Mortgage Indenture and all the Bonds are solely corporate obligations and that any such personal liability is hereby expressly waived and released as a condition of, and as part of the consideration for, the execution of the Mortgage Indenture and the issuance of this Bond.

All terms used in this Bond which are not defined herein shall have the meanings assigned to them in the Mortgage Indenture.

This 5.450% First Mortgage Bond due 2027 is one of a duly authorized issue of Bonds of the Company (the “Bonds”), issued and issuable in one or more series under and equally secured by an Indenture of Mortgage, dated as of June 19, 2020 (such Mortgage Indenture as originally executed and delivered and as supplemented or amended from time to time thereafter, together with any constituent instruments establishing the terms of particular Bonds, being herein called the “Mortgage Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Mortgage Indenture), and reference is hereby made to the Mortgage Indenture for a description of the property mortgaged, pledged and held in trust, the nature and extent of the security and the respective rights, limitations of rights, duties and immunities of the Company, the Trustee and the Holders of Bonds thereunder and of the terms and conditions upon which Bonds are, and are to be, authenticated and delivered. The acceptance of this Bond shall be deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Mortgage Indenture.

The Company shall not be required to make any mandatory redemption or sinking fund payments with respect to the Bonds of this series.

Subject to the terms and conditions of the Mortgage Indenture, prior to the Par Call Date, the Company may redeem the Bonds of this series at its option (“Optional Redemption”), in whole or in part, at any time and from time to time, at a Redemption Price (expressed as a percentage of the principal amount and rounded to three decimal places) equal to the greater of: (1)(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Bonds of this series matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 40 basis points, less (b) interest accrued to the Redemption Date; and (2) 100% of the principal amount of the Bonds of this series to be redeemed, plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

Subject to the terms and conditions of the Mortgage Indenture, on or after the Par Call Date, the Company may redeem the Bonds of this series, in whole or in part, at any time and from time to time, at a Redemption Price equal to 100% of the principal amount of the Bonds of this series being redeemed plus accrued and unpaid interest thereon to the Redemption Date.

For purposes of determining the Redemption Price, the following terms have the following meanings:

“Par Call Date” means May 15, 2027.

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Company in accordance with the following two paragraphs.

B-6

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities—Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third Business Day preceding the Redemption Date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the applicable Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

Interest installments whose Stated Maturity is on or prior to such Redemption Date will be payable to Holders of such Bonds of this series, or one or more Predecessor Bonds, of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Mortgage Indenture.

In the case of an Optional Redemption, notice of redemption will be sent not less than 10 days nor more than 60 days prior to the Redemption Date to each Holder of Bonds of this series to be redeemed. If money sufficient to pay the Redemption Price of all Bonds of this series (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent or the Trustee on or prior to the Redemption Date, from and after such Redemption Date such Bonds of this series or portions thereof shall cease to bear interest. The Bonds of this series in denominations larger than $2,000 in principal amount may be redeemed in part but only in integral multiples of $1,000.

B-7

In the case of a partial redemption, selection of the Bonds of this series for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. No Bonds of this series of a principal amount of $2,000 or less will be redeemed in part. If any Bond of this series is to be redeemed in part only, the notice of redemption that relates to the Bond of this series will state the portion of the principal amount of the Bond of this series to be redeemed. A new Bond of this series in a principal amount equal to the unredeemed portion of the Bond of this series will be issued in the name of the Holder of the Bond of this series upon surrender for cancellation of the original Bond of this series. For so long as the Bonds of this series are held by DTC (or another Depositary), the redemption of the Bonds of this series shall be done in accordance with the policies and procedures of the Depositary.

As provided in the Mortgage Indenture and subject to certain limitations therein set forth, this Bond or any portion of the principal amount hereof will be deemed to have been paid for all purposes of the Mortgage Indenture and to be no longer Outstanding thereunder, and the Company’s entire indebtedness in respect thereof will be satisfied and discharged, if there has been irrevocably deposited with the Trustee or any Paying Agent (other than the Company), in trust, money in an amount which will be sufficient and/or Eligible Obligations, the principal of and interest on which when due, without regard to any reinvestment thereof, will provide moneys which, together with money, if any, deposited with or held by the Trustee or such Paying Agent, will be sufficient to pay when due the principal of and premium, if any, and interest on this Bond when due.

If an Event of Default shall occur and be continuing as provided in the Mortgage Indenture, the Trustee or the Holders of not less than 25% in aggregate principal amount of Bonds then Outstanding, considered as one class, may declare the principal amount of all Bonds then Outstanding to be due and payable immediately by notice in writing to the Company (and to the Trustee if given by Holders); provided, however, that with respect to certain Events of Default relating to bankruptcy, insolvency and similar events, the principal amount of all Bonds then Outstanding shall be due and payable immediately without further action by the Trustee or the Holders.

The Mortgage Indenture permits, with certain exceptions as therein provided, the Company and the Trustee to enter into one or more supplemental indentures for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, the Mortgage Indenture with the consent of the Holders of not less than a majority in aggregate principal amount of the Bonds at the time Outstanding, considered as one class; provided, however, that if there shall be Bonds of more than one series Outstanding under the Mortgage Indenture and if a proposed supplemental indenture shall directly affect the rights of the Holders of Bonds of one or more, but less than all, of such series, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Bonds of all series so directly affected, considered as one class, shall be required; and provided, further, that if the Bonds of any series shall have been issued in more than one Tranche and if a proposed supplemental indenture shall directly affect the rights of the Holders of Bonds of one or more, but less than all, of such Tranches, then the consent only of the

B-8

Holders of a majority in aggregate principal amount of the Outstanding Bonds of all Tranches so directly affected, considered as one class, shall be required; and provided, further, that the Mortgage Indenture permits the Company and the Trustee to enter into one or more supplemental indentures for certain purposes without the consent of any Holders of Bonds. The Mortgage Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of Bonds, on behalf of the Holders of all such Bonds, to waive certain past defaults under the Mortgage Indenture and their consequences. Any such consent or waiver by the Holder of this Bond shall be conclusive and binding upon such Holder and upon all future Holders of this Bond and of any Bond 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 Bond.

As provided in and subject to the provisions of the Mortgage Indenture, the Holder of this Bond shall not have the right to institute any proceeding with respect to the Mortgage 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 a continuing Event of Default, the Holders of at least 25% in aggregate principal amount of the Bonds at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of at least a majority in aggregate principal amount of Bonds at the time Outstanding a direction inconsistent with such written request, and shall have failed to institute any such proceeding for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Bond 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 Mortgage Indenture and no provision of this Bond or of the Mortgage 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 Bond at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Mortgage Indenture and subject to certain limitations therein set forth, the transfer of this Bond is registrable in the Bond Register, upon surrender of this Bond for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Bond are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company, the Trustee or the Bond Registrar, as the case may be, duly executed by the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Bonds 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.

The Bonds of this series are issuable only in registered form without coupons in denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Mortgage Indenture and subject to certain limitations therein set forth, Bonds of this series are exchangeable for a like aggregate principal amount of Bonds of this series and of like tenor of a different authorized denomination, as requested by the Holders surrendering the same.

B-9

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

The Company shall not be required to execute or to provide for the registration of the transfer of or the exchange of (A) any Bond of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers (or with respect to Global Bonds, CUSIP numbers) of the Bonds of this series called for redemption, or (B) any Bond of this series selected for redemption in whole or in part, except the unredeemed portion of any Bond of this series being redeemed in part.

Prior to due presentment of this Bond for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Bond is registered as the owner hereof for all purposes, whether or not this Bond is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

This Bond shall be governed by, and construed and enforced in accordance with, the laws of the State of New York without regard to the principles of conflicts of laws thereunder, except to the extent that the Trust Indenture Act shall be applicable.

As provided in the Mortgage Indenture, no recourse shall be had for the payment of the principal of, premium, if any, or interest with respect to this Bond, or any part thereof, or for any claim based hereon or otherwise in respect hereof, or of the indebtedness represented hereby, or upon any obligation, covenant or agreement under the Mortgage Indenture, against any incorporator, shareholder, officer or director, as such, past, present or future, of the Company or of any predecessor or successor corporation (either directly or through the Company or a predecessor or successor corporation), whether by virtue of any constitutional provision, statute or rule of law or by the enforcement of any assessment or penalty or otherwise; it being expressly agreed and understood that the Mortgage Indenture and all the Bonds are solely corporate obligations and that any such personal liability is hereby expressly waived and released as a condition of, and as part of the consideration for, the execution of the Mortgage Indenture and the issuance of this Bond.

[FORM OF REVERSE OF 5.900% FIRST MORTGAGE BOND DUE 2032]

This 5.900% First Mortgage Bond due 2032 is one of a duly authorized issue of Bonds of the Company (the “Bonds”), issued and issuable in one or more series under and equally secured by an Indenture of Mortgage, dated as of June 19, 2020 (such Mortgage Indenture as originally executed and delivered and as supplemented or amended from time to time thereafter, together with any constituent instruments establishing the terms of particular Bonds, being herein called the “Mortgage Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Mortgage Indenture), and reference is hereby made to the Mortgage Indenture for a description of the property mortgaged, pledged and held in trust, the nature and extent of the security and the respective rights, limitations of rights, duties and immunities of the Company, the Trustee and the Holders of Bonds thereunder and of the terms and conditions upon which Bonds are, and are to be, authenticated and delivered. The acceptance of this Bond shall be deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Mortgage Indenture.

The Company shall not be required to make any mandatory redemption or sinking fund payments with respect to the Bonds of this series.

Subject to the terms and conditions of the Mortgage Indenture, prior to the Par Call Date, the Company may redeem the Bonds of this series at its option (“Optional Redemption”), in whole or in part, at any time and from time to time, at a Redemption Price (expressed as a percentage of the principal amount and rounded to three decimal places) equal to the greater of: (1)(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Bonds of this series matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 45 basis points, less (b) interest accrued to the Redemption Date; and (2) 100% of the principal amount of the Bonds of this series to be redeemed, plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

Subject to the terms and conditions of the Mortgage Indenture, on or after the Par Call Date, the Company may redeem the Bonds of this series, in whole or in part, at any time and from time to time, at a Redemption Price equal to 100% of the principal amount of the Bonds of this series being redeemed plus accrued and unpaid interest thereon to the Redemption Date.

For purposes of determining the Redemption Price, the following terms have the following meanings:

“Par Call Date” means March 15, 2032.

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Company in accordance with the following two paragraphs.

C-6

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities—Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third Business Day preceding the Redemption Date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the applicable Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

Interest installments whose Stated Maturity is on or prior to such Redemption Date will be payable to Holders of such Bonds of this series, or one or more Predecessor Bonds, of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Mortgage Indenture.

In the case of an Optional Redemption, notice of redemption will be sent not less than 10 days nor more than 60 days prior to the Redemption Date to each Holder of Bonds of this series to be redeemed. If money sufficient to pay the Redemption Price of all Bonds of this series (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent or the Trustee on or prior to the Redemption Date, from and after such Redemption Date such Bonds of this series or portions thereof shall cease to bear interest. The Bonds of this series in denominations larger than $2,000 in principal amount may be redeemed in part but only in integral multiples of $1,000.

C-7

In the case of a partial redemption, selection of the Bonds of this series for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. No Bonds of this series of a principal amount of $2,000 or less will be redeemed in part. If any Bond of this series is to be redeemed in part only, the notice of redemption that relates to the Bond of this series will state the portion of the principal amount of the Bond of this series to be redeemed. A new Bond of this series in a principal amount equal to the unredeemed portion of the Bond of this series will be issued in the name of the Holder of the Bond of this series upon surrender for cancellation of the original Bond of this series. For so long as the Bonds of this series are held by DTC (or another Depositary), the redemption of the Bonds of this series shall be done in accordance with the policies and procedures of the Depositary.

As provided in the Mortgage Indenture and subject to certain limitations therein set forth, this Bond or any portion of the principal amount hereof will be deemed to have been paid for all purposes of the Mortgage Indenture and to be no longer Outstanding thereunder, and the Company’s entire indebtedness in respect thereof will be satisfied and discharged, if there has been irrevocably deposited with the Trustee or any Paying Agent (other than the Company), in trust, money in an amount which will be sufficient and/or Eligible Obligations, the principal of and interest on which when due, without regard to any reinvestment thereof, will provide moneys which, together with money, if any, deposited with or held by the Trustee or such Paying Agent, will be sufficient to pay when due the principal of and premium, if any, and interest on this Bond when due.

If an Event of Default shall occur and be continuing as provided in the Mortgage Indenture, the Trustee or the Holders of not less than 25% in aggregate principal amount of Bonds then Outstanding, considered as one class, may declare the principal amount of all Bonds then Outstanding to be due and payable immediately by notice in writing to the Company (and to the Trustee if given by Holders); provided, however, that with respect to certain Events of Default relating to bankruptcy, insolvency and similar events, the principal amount of all Bonds then Outstanding shall be due and payable immediately without further action by the Trustee or the Holders.

The Mortgage Indenture permits, with certain exceptions as therein provided, the Company and the Trustee to enter into one or more supplemental indentures for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, the Mortgage Indenture with the consent of the Holders of not less than a majority in aggregate principal amount of the Bonds at the time Outstanding, considered as one class; provided, however, that if there shall be Bonds of more than one series Outstanding under the Mortgage Indenture and if a proposed supplemental indenture shall directly affect the rights of the Holders of Bonds of one or more, but less than all, of such series, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Bonds of all series so directly affected, considered as one class, shall be required; and provided, further, that if the Bonds of any series shall have been issued in more than one Tranche and if a proposed supplemental indenture shall directly affect the rights of the Holders of Bonds of one or more, but less than all, of such Tranches, then the consent only of the

The Mortgage Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of Bonds, on behalf of the Holders of all such Bonds, to waive certain past defaults under the Mortgage Indenture and their consequences. Any such consent or waiver by the Holder of this Bond shall be conclusive and binding upon such Holder and upon all future Holders of this Bond and of any Bond 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 Bond.

As provided in and subject to the provisions of the Mortgage Indenture, the Holder of this Bond shall not have the right to institute any proceeding with respect to the Mortgage 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 a continuing Event of Default, the Holders of at least 25% in aggregate principal amount of the Bonds at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of at least a majority in aggregate principal amount of Bonds at the time Outstanding a direction inconsistent with such written request, and shall have failed to institute any such proceeding for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Bond 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 Mortgage Indenture and no provision of this Bond or of the Mortgage 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 Bond at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Mortgage Indenture and subject to certain limitations therein set forth, the transfer of this Bond is registrable in the Bond Register, upon surrender of this Bond for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Bond are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company, the Trustee or the Bond Registrar, as the case may be, duly executed by the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Bonds 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.

The Bonds of this series are issuable only in registered form without coupons in denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Mortgage Indenture and subject to certain limitations therein set forth, Bonds of this series are exchangeable for a like aggregate principal amount of Bonds of this series and of like tenor of a different authorized denomination, as requested by the Holders surrendering the same.

C-9

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

The Company shall not be required to execute or to provide for the registration of the transfer of or the exchange of (A) any Bond of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers (or with respect to Global Bonds, CUSIP numbers) of the Bonds of this series called for redemption, or (B) any Bond of this series selected for redemption in whole or in part, except the unredeemed portion of any Bond of this series being redeemed in part.
