SEMPRA ENERGY

Floating Rate Notes due 2021

Sempra Energy, a corporation duly organized and existing under the laws of the State of California (herein called the “Corporation,” which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & CO., or registered assigns, the principal sum of                     Million Dollars ($        ) on March 15, 2021 (the “Maturity Date”), and to pay interest thereon from October 13, 2017 (the “Original Issue Date”) or from the most recent date to which interest has been paid or duly provided for on the Securities (as defined on the reverse hereof) of this series, quarterly in arrears on March 15, June 15, September 15 and December 15 of each year (each, an “Interest Payment Date”), beginning on December 15, 2017, and on the Maturity Date at the Applicable Rate (as defined below), until the principal hereof is paid or made available for payment, provided that any principal hereof or (to the extent that the payment of such interest shall be legally enforceable) interest hereon which is not paid when due shall bear interest at the Applicable Rate from the respective dates such amounts are due until they are paid or made available for payment, and such interest shall be payable on demand; and provided, further that if any Interest Payment Date (other than the Interest Payment Date falling on the Maturity Date) is not a Floating Rate Business Day (as defined below), such Interest Payment Date will be moved to, and will be, the immediately succeeding Floating Rate Business Day, except that if such immediately succeeding Floating Rate Business Day is in the immediately succeeding calendar month, such Interest Payment Date (other than the Interest Payment Date falling on the Maturity Date) will be moved to, and will be, the immediately preceding Floating Rate Business Day. If the Maturity Date is not a Floating Rate Business Day, the Corporation will pay interest and principal due on the Maturity Date on the immediately succeeding day that is a Floating Rate Business Day as if such payment were made on the date such payment was originally due, and no interest will accrue on the amounts so payable for the period from and after the Maturity Date to the immediately succeeding Floating Rate Business Day.

The term “Applicable Rate” means a per annum interest rate determined as follows: the Applicable Rate for the period from and including the Original Issue Date to but excluding the Interest Payment Date falling in December 2017 will be a per annum rate equal to the 3 Month LIBOR Rate (as defined below), determined as of the second London Banking Day (as defined below) immediately preceding the Original Issue Date, plus 45 basis points, and the

Applicable Rate will be reset on each Interest Payment Date (each of these dates is called an “Interest Reset Date”), beginning with the Interest Reset Date falling in December 2017, and will be a per annum rate equal to the 3 Month LIBOR Rate, determined as of the second London Banking Day immediately preceding the applicable Interest Reset Date, plus 45 basis points. The interest rate on this Security (as defined on the reverse hereof) will in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law of general application.

Interest payable on any Interest Payment Date or on the Maturity Date shall be the amount of interest accrued from, and including, the immediately preceding Interest Payment Date in respect of which interest has been paid or duly provided for on the Securities of this series (or from and including the Original Issue Date if no interest has been paid or duly provided for) to, but not including, such Interest Payment Date or the Maturity Date, as the case may be.

The 3 Month LIBOR Rate will be determined by the Calculation Agent (as defined on the reverse hereof) in accordance with the following provisions:

“3 Month LIBOR Rate” means the rate for deposits in U.S. dollars for the 3-month period commencing on the applicable Interest Reset Date which appears on Reuters Screen LIBOR01 Page (as defined below) at approximately 11:00 a.m., London time, on the second London Banking Day prior to such Interest Reset Date (the second London Banking Day prior to any Interest Reset Date being referred to as an “Interest Determination Date”). If this rate does not appear on the Reuters Screen LIBOR01 Page at approximately 11:00 a.m., London time, on such Interest Determination Date, the Calculation Agent will determine the rate on the basis of the rates at which deposits in U.S. dollars are offered by four major banks in the London interbank market selected by the Calculation Agent at approximately 11:00 a.m., London time, on such Interest Determination Date to prime banks in the London interbank market for a period of three months commencing on such Interest Reset Date and in a principal amount equal to an amount not less than U.S. $1,000,000 that is representative for a single transaction in such market at such time. In such case, the Calculation Agent will request the principal London office of each of the aforesaid major banks to provide a quotation of such rate. If at least two such quotations are provided, the rate for that Interest Reset Date will be the arithmetic mean of the quotations, and, if fewer than two quotations are provided as requested, the rate for that Interest Reset Date will be the arithmetic mean of the rates quoted by three major banks in New York City selected by the Calculation Agent, at approximately 11:00 a.m., New York City time, on such Interest Determination Date for loans in U.S. dollars to leading European banks for a period of three months commencing on that Interest Reset Date and in a principal amount equal to an amount not less than U.S. $1,000,000 that is representative for a single transaction in such market at such time; provided, however, that if the banks selected as aforesaid by the Calculation Agent are not quoting such rates as mentioned in this sentence, the 3 Month LIBOR Rate commencing as of such Interest Reset Date will remain the 3 Month LIBOR Rate determined as of the Interest Determination Date for the immediately preceding Interest Reset Date. Solely for purposes of this paragraph, the term “Interest Reset Date” shall be deemed to include the Original Issue Date.

The term “London Banking Day” means any day on which dealings in U.S. dollars are transacted in the London interbank market. The term “Floating Rate Business Day” means any day (1) that is a Business Day (as defined in the Indenture (as defined on the reverse hereof) in The City of New York, and (2) that is also a London Banking Day.

The term “Reuters Screen LIBOR01 Page” means the display designated on page “LIBOR01” on Reuters (or such other page as may replace the LIBOR01 page on that service or any successor service for the purpose of displaying London interbank offered rates for U.S. dollar deposits of major banks).

U.S. Bank National Association will initially act as Calculation Agent for the Securities of this series until such time, if any, as the Corporation shall appoint a successor Calculation Agent. The Calculation Agent will, upon the request of the Holder of this Security, provide the interest rate then in effect. All calculations made by the Calculation Agent in the absence of manifest error shall be conclusive for all purposes and binding on the Corporation and the Holder of this Security. The Corporation may appoint a successor Calculation Agent with the written consent of the Trustee.

2

All percentages resulting from any calculation of the interest rate with respect to this Security will be rounded, if necessary, to the nearest one-hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards (for example, 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655) and 9.876544% (or .09876544) being rounded to 9.87654% (or .0987654), and all dollar amounts in or resulting from any such calculation will be rounded to the nearest cent (with one-half cent being rounded upwards).

The amount of interest for each day the Securities of this series are outstanding (the “Daily Interest Amount”) will be calculated by dividing the interest rate in effect on the Securities of this series on that day by 360 and multiplying the result by the principal amount of the Securities of this series. The amount of interest payable on the Securities of this series on any Interest Payment Date or the Maturity Date will be calculated by adding the Daily Interest Amounts for the Securities of this series for each day in the applicable Interest Period (as defined below). The term “Interest Period” means the period beginning on, and including, an Interest Payment Date to, but excluding, the next succeeding Interest Payment Date or the Maturity Date, as the case may be; provided that the initial Interest Period for the Securities of this series will be the period beginning on, and including, the Original Issue Date to, but excluding, the Interest Payment Date falling in 2017. The amount of interest payable on the Securities of this series on any day, other than an Interest Payment Date or the Maturity Date, on which interest on the Securities of this series is due and payable will be calculated by adding the Daily Interest Amounts for the Securities of this series for each day from and including the most recent date to which interest on the Securities of this series has been paid or duly provided for to but excluding the date such payment of interest is due.

The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the 15th calendar day (whether or not a Floating Rate Business Day), immediately preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for on any Interest Payment Date will forthwith cease to be payable to the Holder on such Regular Record Date by virtue of having been such Holder and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

Payment of the principal of and interest on this Security will be made at the office or agency of the Corporation maintained for that purpose in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at the option of the Corporation payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or by wire transfer at such place and to such account at a banking institution in the United States as may be designated in writing to the Trustee at least 15 days prior to the date for payment by the Person entitled thereto. Notwithstanding the foregoing, so long as the Holder of this Security is the Depositary or its nominee, payment of the principal of and interest on this Security will be made by wire transfer of immediately available funds.

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

This Security is one of the series designated on the face hereof, initially limited (subject to exceptions provided in the Indenture) in aggregate principal amount to $850,000,000.

In connection with the issuance of the Securities of this series, the Corporation has entered into a Calculation Agent Agreement dated as of October 13, 2017 (as the same may be amended or supplemented from time to time and including any successor agreement thereto, the “Calculation Agreement”) with U.S. Bank National Association, as calculation agent (in such capacity herein called the “Calculation Agent,” which term includes any successor thereto under the Calculation Agreement).

This Security is not subject to redemption at the option of the Corporation.

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

If an Event of Default with respect to the Securities of this series shall occur and be continuing, the principal of and accrued and unpaid interest on the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Corporation and the rights of the Holders of the Securities of each series affected under the Indenture at any time by the Corporation and the Trustee with the consent of the Holders of a majority in principal amount of the Securities of each series at the time Outstanding affected thereby. The Indenture contains provisions permitting the Holders of not less than a majority in principal amount of the Securities of any series at the time Outstanding with respect to which a default under the Indenture shall have occurred and be continuing, on behalf of the Holders of all Securities of such series, to waive, with certain exceptions, such past default with respect to such series and its consequences. The Indenture also permits the Holders of not less than a majority in principal amount of the Securities of any series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Corporation with certain provisions of the Indenture. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee, such Holder or Holders shall have offered the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and the Trustee, for 60 days after its receipt of such notice, request and offer of indemnity, shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and the Trustee 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 Security for the enforcement of any payment of principal hereof or interest hereon on or after the respective due dates expressed herein.

5

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

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Corporation in any place where the principal of and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Corporation and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities 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 Securities of this series are issuable only in fully registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

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