(Form of Definitive Series 2024F Bond)

SOUTHERN CALIFORNIA EDISON COMPANY

First and Refunding Mortgage Bonds, Series 2024F, Due 2031

​

​

SOUTHERN CALIFORNIA EDISON COMPANY, a corporation organized and existing under and by virtue of the laws of the State of California (hereinafter called the “Company”), for value received, hereby promises to pay to _____________________, the registered owner hereof, the principal sum of $750,000,000 on June 1, 2031, and to pay interest on the unpaid principal amount hereof to the registered owner hereof from May 9, 2024, until said principal sum shall be paid, at the rate of 5.45% per annum, payable semiannually on June 1 and December 1 of each year (each, a “Series 2024F Payment Date”), beginning December 1, 2024. Such interest shall be paid to the person in whose name this Bond is registered at the close of business on (1) the business day immediately preceding the Series 2024F Payment Date if this Bond is in book-entry only form, or (2) the 15^th calendar day before each Series 2024F Payment Date if this Bond is not in book-entry only form. The amount of interest payable for any period shall be computed on the basis of a 360-day year consisting of twelve 30-day months, provided that the amount of interest payable for any period shorter or longer than a full interest period will be completed on the basis of a 360-day year consisting of twelve 30-day months and the actual number of days elapsed in the period using 30-day months.

The principal of and interest on this Bond are payable at the offices of The Bank of New York Mellon Trust Company, N.A., as Trustee, in Chicago, Illinois, or at such other agency or agencies as may be designated by the Company, in such coin or currency of the United States of America as at the time of payment is legal tender for public and private debts.

This Bond is one of a series, designated as “Series 2024F, Due 2031,” of a duly authorized issue of bonds of the Company, known as its “First and Refunding Mortgage Bonds,” issued and to be issued in one or more series under and all equally and ratably secured by a Trust Indenture dated as of October 1, 1923, and indentures supplemental thereto, including the One Hundred Fifty-Eighth Supplemental Indenture, to be dated as of May 7, 2024, which have been duly executed, acknowledged and delivered by the Company to The Bank of New York Mellon Trust Company, N.A. and Reginald Brewer, or one of their predecessors, as Trustees, to which original indenture and indentures supplemental thereto (collectively, the “Trust Indenture”) reference is hereby made for a description of the property, rights and franchises thereby mortgaged and pledged, the nature and extent of the security thereby created, the rights of the holders of this Bond and of the Trustees in respect of such security, and the terms, restrictions and conditions upon which the bonds are issued and secured.

​

Prior to April 1, 2031, the Company may redeem this Bond at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of 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 15 basis points in the case of the Series 2024F Bonds less (b) interest accrued to the date of redemption, and

(2) 100% of the principal amount of this Bond to be redeemed,

plus, accrued and unpaid interest thereon to the redemption date.

​

“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 applicable 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 applicable 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 applicable Par Call Date. If there is no United States Treasury security maturing on the applicable 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 such Par Call Date and one with a maturity date following such Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding such Par Call Date. If there are two or more United States Treasury securities maturing on the applicable 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.

If the Company elects to redeem fewer than all the Series 2024F Bonds, The Bank of New York Mellon Trust Company, N.A., as Trustee, will select the particular bonds to be redeemed by lot; provided, however, that as long as this Bond is held with a depositary, any such selection shall be in accordance with such depositary’s applicable procedures.

​

Any notice of redemption, at the Company’s option, may state that the redemption will be conditional upon receipt by the paying agent, on or prior to the date fixed for the redemption, of money sufficient to pay the principal of and premium, if any, and interest, if any, on the Series 2024F Bonds to be redeemed and that if the money has not been so received, the notice will be of no force and effect and the Company will not be required to redeem this Bond.

​

The Trust Indenture makes provision for a Special Trust Fund and permits the use of moneys therein for the purpose, among others, of redeeming or purchasing this Bond.

​

If default shall be made in the payment of any installment of principal of or interest on this Bond or in the performance or observance of any of the covenants and agreements contained in the Trust Indenture, and such default shall continue as provided in the Trust Indenture, then the principal of this Bond may be declared and become due and payable as provided in the Trust Indenture.

​

This Bond is transferable only on the books of the Company at any of the places designated above for the payment of the principal of and premium, if any, or interest on this Bond, or at such other agency or agencies as may be designated by the Company, by the registered owner or by an attorney of such owner duly authorized in writing, on surrender hereof properly endorsed, and upon such surrender hereof, and the payment of charges, a new registered bond or bonds of this series, of an equal aggregate principal amount, will be issued to the transferee in lieu hereof, as provided in the Trust Indenture.

​

The terms of the Trust Indenture may be modified as set forth in the Trust Indenture; provided, however, that, among other things, (1) the obligation of the Company to pay the principal of and premium, if any, and interest on all bonds outstanding under the Trust Indenture, as at the time in effect, shall continue unimpaired, (2) no modification shall give any of said bonds any preference over any other of said bonds, and (3) no modification shall authorize the creation of any lien prior to the lien of the Trust Indenture on any of the trust property.

​

No recourse shall be had for the payment of the principal of and premium, if any, or interest on this Bond, or any part thereof, or for or on account of the consideration herefor, or for any claim based hereon, or otherwise in respect hereof, or of the Trust Indenture, against any past, present or future stockholder, officer or director of the Company or of any predecessor or successor company, whether for amounts unpaid on stock subscriptions, or by virtue of any statue

or constitution, or by the enforcement of any assessment or penalty, or because of any representation or inference arising from the capitalization of the Company or of such predecessor or successor company, or otherwise; all such liability being, by the acceptance hereof and as a part of the consideration for the issue hereof, expressly released.

​

This Bond shall not be valid or obligatory for any purpose until it shall have been authenticated by the execution of the certificate of authentication hereon of The Bank of New York Mellon Trust Company, N.A., as Trustee, or its successor in trust.

​

IN WITNESS WHEREOF, Southern California Edison Company has caused this Bond to be executed in its name by its President or one of its Vice Presidents and its corporate seal to be hereto affixed and attested by its Secretary or one of its Assistant Secretaries, as of May__, 2024, such execution and attestation to be by manual or facsimile signatures.
