 ANNEX I 

Capitalized terms used in this Annex I and not otherwise defined herein have the same definitions as in the Indenture referred to in the
Officers’ Certificate of which this Annex I constitutes a part. 
 (1)     One series of debt securities is
established hereby and shall be known and designated as the “Floating Rate Notes due 2023” (hereinafter referred to as the “Securities,” “Securities of such series” or the “Notes”). 

(2)     The aggregate principal amount of the Securities of such series which may be authenticated and delivered under the
Indenture is limited to $300,000,000, except for Securities of such series authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Securities of the same series pursuant to Sections 304, 305, 306, 906
or 1106 of the Indenture and except for any Securities of such series which, pursuant to Section 303 of the Indenture, are deemed never to have been authenticated and delivered under the Indenture. However, such series of Securities may be re-opened by the Corporation for the issuance of additional Securities of the same series (so long as any such additional Securities of such series have the same form and terms (other than offering price, the date
of original issuance and, if applicable, the date from which interest thereon shall begin to accrue and the first interest payment date), and carry the same right to receive accrued and unpaid interest, as the Securities of such series theretofore
issued) and such additional Securities of such series shall form a single series under the Indenture with the Securities of such series theretofore issued; provided that such additional Securities of such series are fungible with the Securities of
such series theretofore issued for United States Federal income tax purposes; provided, however, that, notwithstanding the foregoing, such series of Securities may not be re-opened if the Corporation has
effected defeasance or covenant defeasance with respect to the Securities of such series pursuant to Section 1302 or 1303, as applicable, of the Indenture or has effected satisfaction and discharge with respect to the Securities of such series
pursuant to Section 401 of the Indenture. 
 (3)     The Securities of such series are to be issued only as
registered securities without coupons. The Securities of such series shall be issued in book-entry form and represented by one or more global Securities (the “Global Securities”) of such series, the initial depositary (the
“Depositary”) for the Global Securities of such series shall be The Depository Trust Company and the depositary arrangements shall be those employed by whoever shall be the Depositary with respect to the Global Securities of such
series from time to time. Notwithstanding the foregoing, certificated Securities of such series in definitive form may be issued in exchange for Global Securities of such series under the circumstances contemplated by Section 305 of the
Indenture. 
 (4)     The Securities of such series shall be sold by the Corporation to the several underwriters (the
“Underwriters”) named in Schedule I to the Underwriting Agreement dated September 14, 2020 among the Corporation and BMO Capital Markets Corp., U.S. Bancorp Investments, Inc. and Wells Fargo Securities, LLC, as

100.000% of the principal amount of the Securities of such series (plus accrued and unpaid interest, if any), 

  
 Annex I-1 













 
and underwriting discounts and commissions shall be 0.350% of the principal amount of the Securities of such series. 

(5)     The Securities of such series shall not be repayable or redeemable at the option of the Holders prior to the
Stated Maturity of the principal of the Securities of such series (except as provided in Article V of the Indenture) and shall not be subject to a sinking fund or analogous provision. 

(6)     The Borough of Manhattan, The City of New York is hereby designated as a Place of Payment for the Securities of
such series. 
 (7)     The Corporation hereby appoints the Trustee, acting through its Corporate Trust Office in the
Borough of Manhattan, The City of New York, as the Corporation’s agent for the purposes specified in Section 1002 of the Indenture with respect to the Securities of such series; provided, however, subject to Section 1002 of the
Indenture, the Corporation may at any time remove the Trustee as its office or agency in the Borough of Manhattan, The City of New York designated for such purposes with respect to the Securities of such series and may from time to time designate
one or more other offices or agencies for such purposes and one or more other Places of Payment with respect to the Securities of such series and may from time to time rescind such designation, so long as the Corporation shall at all times maintain
an office or agency for such purposes with respect to the Securities of such series in the Borough of Manhattan, The City of New York. 

(8)     The Securities of such series shall be issued in denominations of $2,000 and integral multiples of $1,000 in
excess thereof. 
 (9)     The principal of, premium, if any, and interest on the Securities of such series shall be
payable in U.S. dollars. 
 (10)     The Securities of such series shall not be convertible into or exchangeable for
other securities. 
 (11)     Anything in the Indenture or the Securities of such series to the contrary
notwithstanding, payments of the principal of, premium, if any, and interest on the Global Securities of such series shall be made by wire transfer to the Depositary or its nominee or to any successor Depositary or nominee, whichever shall be the
registered Holder of such Global Securities of such series from time to time. 
 (12)     To the extent that any
provision of the Indenture or the Securities of such series provides for the payment of interest on overdue principal of, premium, if any, or interest on, the Securities of such series, then, to the extent permitted by law, interest on such overdue
principal, premium, if any, and interest shall accrue at the rate of interest borne by the Securities of such series from time to time. 

(13)     The Securities of such series shall have such other terms and provisions as are set forth in the form of
certificate evidencing the Securities of such series attached as Annex II to the Officers’ Certificate of which this Annex I constitutes a part (the “Form of Note”), all of which


  
 Annex I-2 













 
terms and provisions are incorporated by reference in and made a part of this Annex I as if set forth in full herein. 

(14) As used in the Indenture with respect to the Securities of such series and in the certificates evidencing the Securities of such series,
all references to “premium” on the Securities of such series shall mean any amounts (other than accrued interest) payable upon the redemption of any Securities of such series in excess of 100% of the principal amount of such Securities.

 (15) Neither the Trustee nor any Paying Agent shall be under any obligation (i) to monitor, determine or verify the unavailability

Replacement Date (as such terms are defined in the Form of Note), (ii) to select, determine or designate any alternative reference rate or Benchmark Replacement (as defined in the Form of Note), or other successor or replacement benchmark index, or

successor index, or (iv) to determine whether or what Benchmark Replacement Conforming Changes (as defined in the Form of Note) are necessary or advisable, if any, in connection with any of the foregoing. 

Neither the Trustee nor any Paying Agent shall be liable for any inability, failure or delay on its part to perform any of its duties set
forth in the Indenture as a result of the unavailability of LIBOR (or other applicable Benchmark) and absence of a designated replacement Benchmark, including as a result of any inability, delay, error or inaccuracy on the part of any other Person,
including without limitation any Designee (as defined in the Form of Note), in providing any direction, instruction, notice or information required or contemplated by the terms of the Notes or the Calculation Agreement (as defined in the Form of
Note) and reasonably required for the performance of such duties. 
 Neither the Trustee nor any Paying Agent shall be responsible or liable
for the actions or omissions of the Corporation or any Designee or any failure or delay in the performance of their duties or obligations in relation to the determination of the interest rate on the Notes, nor shall the Trustee or any Paying Agent
be under any obligation to oversee or monitor such performance of the Corporation or any Designee; and each of the Trustee and each Paying Agent shall be entitled to rely conclusively upon any determination made, and any instruction, notice,
officers’ certificate or other instrument or information provided, by the Corporation in accordance with the notice provisions of the Indenture or the Designee, without independent verification, investigation or inquiry of any kind by the
Trustee or Paying Agent. 
 If the Corporation appoints a Designee or any successor or replacement Designee, it shall promptly notify the
Trustee and any Paying Agent of such appointment in accordance with the notice provisions of the Indenture, and neither the Trustee nor any Paying Agent shall treat any third party as a Designee with respect to the Notes until any such notice is
given. Neither the Trustee nor any Paying Agent shall be under any duty to succeed to, assume or otherwise perform any of the duties of any Designee, or to appoint a successor or replacement in the event of any Designee’s resignation or

 Southern California Gas Company, 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 [●], or registered assigns, the principal sum of
[●] Dollars ($[●]) on September 14, 2023 (the “Maturity Date”), and to pay interest thereon from September 21, 2020 (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 14, June 14, September 14 and December 14 of each year (each, an “Interest Payment
Date”), beginning on December 14, 2020, 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) premium, if any, or 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 (a) the Interest Payment Date falling on the Maturity Date of the Securities of this series and
(b) any Interest Payment Date falling on a Redemption Date for the Securities of this series, provided that this clause (b) shall only be applicable to the Securities of this series that are being redeemed on such Redemption Date and not
to any Securities of this series that are not being redeemed on such Redemption 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 (a) the Interest Payment Date falling on the Maturity Date of the Securities of
this series and (b) any Interest Payment Date falling on a Redemption Date for the Securities of this series, provided that this clause (b) shall only be applicable to the Securities of this series that are being redeemed on such
Redemption Date and not to any Securities of this series that are not being redeemed on such Redemption Date) will be moved to, and will be, the immediately preceding Floating Rate Business Day. If the Maturity Date or any Redemption Date of the
Securities of this series is not a Floating Rate Business Day, the Corporation will pay interest, principal and premium, if any, due on the Maturity Date or such Redemption Date, as the case may be, 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 or such Redemption Date, as the case may be,
to the immediately succeeding Floating Rate Business Day. 

  
 Annex II-2 













 The term “Applicable Rate” means the per annum interest rate on the
Securities of this series, determined as provided below, as in effect from time to time. 
 This Security will bear interest for each
Interest Period (as defined below) at a per annum rate determined by the Calculation Agent (as defined on the reverse hereof) or, in certain circumstances described below, by the Corporation or its designee (which may be an independent financial
advisor or any other entity the Corporation designates (any of such entities, a “Designee”)). The interest rate on this Security for the period from and including the Original Issue Date to, but excluding, the Interest Payment Date
falling in December 2020 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 35 basis points (the
“Margin”). Subject to the provisions set forth below, interest on this Security will be reset on each Interest Payment Date (each of these dates is also called an “Interest Reset Date”), beginning with the Interest
Reset Date falling in December 2020, 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 the Margin. The interest rate on this
Security 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 or lower than 0.00%. 

Interest payable on any Interest Payment Date or Redemption Date or on the Maturity Date of this Security 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 on the Securities of this series) to, but not including, such Interest Payment Date or Redemption Date or the Maturity Date, as the case may be. 

The 3 Month LIBOR Rate will be determined by the Calculation Agent 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 the Bloomberg page BBAM (as defined below) or, if such page is not available, on the Reuters Screen LIBOR01 Page (as defined below), in each case 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 the 3 Month LIBOR Rate cannot
be determined as provided in the immediately preceding sentence, 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, or, 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.

 Notwithstanding the immediately preceding paragraph, if the Corporation (or its Designee) determines on or prior to the relevant Interest
Determination Date that a Benchmark Transition Event and its related Benchmark Replacement Date (as defined below) have occurred with respect to three month U.S. dollar LIBOR (or the then-current Benchmark (as defined below), as applicable), then
the provisions set forth below under “Effect of Benchmark Transition Event,” which are referred to as the “benchmark transition provisions,” will thereafter apply to all determinations of the rate of interest payable on the
Securities of this series. In accordance with the benchmark transition provisions, after a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, the amount of interest that will be payable for each Interest Period will
be an annual rate equal to the sum 

  
 Annex II-3 













 
of the Benchmark Replacement and the Margin. However, if the Corporation (or its Designee) determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred
with respect to the then-current Benchmark, but for any reason the Benchmark Replacement has not been determined as of the relevant Interest Determination Date, the interest rate for the applicable Interest Period will be equal to the interest rate
for the immediately preceding Interest Period, as determined by the Corporation (or its Designee). 
 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 other than (i) a Saturday or Sunday or (ii) a day on which banking institutions in The City of New York are authorized or obligated by law or executive order to remain closed. 

The term “Bloomberg page BBAM” means the display that appears on Bloomberg L.P.’s page “BBAM” or any page as
may replace such page or such service (or any successor service) for the purpose of displaying the London Interbank Offered rate for U.S. dollar deposits. 

The term “Reuters Screen LIBOR01 Page” means the display designated as Reuters page “LIBOR01” on the Reuters 3000
Xtra, or such other page as may replace the LIBOR01 page on that service or such other service as may be nominated for the purpose of displaying rates or prices comparable to the London Interbank Offered rate for U.S. dollar deposits by ICE
Benchmark Administration Limited (“IBA”) or its successor or such other entity assuming the responsibility of IBA or its successor in calculating the London Interbank Offered rate in the event IBA or its successor no longer does so. 

U.S. Bank National Association will act as Calculation Agent for the Securities of this series until such time, if any, as the Corporation
shall appoint a successor Calculation Agent in accordance with the terms of the Calculation Agreement (as defined on the reverse hereof). Promptly upon its determination of the interest rate for an Interest Period, the Calculation Agent will notify
the Corporation, the Trustee and each Paying Agent, or, in certain circumstances described below, the Corporation or its Designee will notify the Corporation (if applicable), the Trustee and each Paying Agent, of the interest rate for the new
Interest Period. The Calculation Agent or, in certain circumstances described below, the Corporation or its Designee, will, upon the request of the Holder of this Security, provide the interest rate then in effect on the Securities of this series.
In no event will the initial Calculation Agent (U.S. Bank National Association) be the Designee. All calculations made by the Calculation Agent, or in certain circumstances described below, by the Corporation or its Designee, in the absence of
manifest error shall be conclusive for all purposes and binding on the Corporation and the Holder of this Security. 
 All percentages
resulting from any calculation of the interest rate with respect to the Securities of this series 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). Any percentage resulting from any calculation of any interest rate for
the Securities of this series less than 0.00% will be deemed to be 0.00% (or 0.0000). 
 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 Redemption 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. The term “Interest Period” means the period beginning on, and including, an Interest Payment Date for the Securities of this series to, but excluding, the next succeeding Interest
Payment Date or Redemption 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 December 2020. The amount of interest payable on the Securities of this series on any day, other than an Interest Payment Date or Redemption 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. 

  
 Annex II-4 













 Neither the Trustee nor the Calculation Agent will have any liability for any determination
made by or on behalf of the Corporation or its Designee in connection with a Benchmark Transition Event or Benchmark Replacement. 
 The
interest 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 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 premium, if any) 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 before the applicable Interest Payment Date 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 premium, if any) and interest on this Security will be made by wire transfer of immediately available funds. 

Effect of Benchmark Transition Event 

Benchmark Replacement 
 If
the Corporation (or its Designee) determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any determination of the Benchmark on any date, the Benchmark
Replacement will replace the then-current Benchmark for all purposes relating to the Securities of this series in respect of such determination on such date and all determinations on all subsequent dates. 

Benchmark Replacement Conforming Changes 

In connection with the implementation of a Benchmark Replacement, the Corporation (or its Designee) will have the right to make Benchmark
Replacement Conforming Changes from time to time. 
 Decisions and Determinations 

Any determination, decision or election that may be made by the Corporation (or its Designee) pursuant to this section “Effect of
Benchmark Transition Event,” including any determination with respect to tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or
refrain from taking any action or any selection, will be conclusive and binding absent manifest error, will be made in the Corporation’s (or its Designee’s) sole discretion, and, notwithstanding anything to the contrary in the
documentation relating to the Securities of this series, shall become effective without consent from the Holders of the Securities of this series or any other party. 

Certain Definitions 
 As
used in this Security: 
 “Benchmark” means, initially, three month U.S. dollar LIBOR; provided that if a Benchmark
Transition Event and its related Benchmark Replacement Date have occurred with respect to three month U.S. dollar LIBOR or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement. 

“Benchmark Replacement” means the Interpolated Benchmark with respect to the then-current Benchmark, plus the Benchmark
Replacement Adjustment for such Benchmark; provided that if the Corporation (or its Designee) cannot determine the Interpolated Benchmark as of the Benchmark Replacement Date, then “Benchmark

 Annex II-9 













 (REVERSE OF SECURITY) 

This Security is one of a duly authorized issue of securities of the Corporation (herein called the “Securities”), issued and
to be issued in one or more series under an Indenture, dated as of September 21, 2020 (herein called the “Indenture,” which term shall have the meaning assigned to it in such instrument), between the Corporation and U.S. Bank
National Association, as trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitation of
rights, duties and immunities thereunder of the Corporation, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on
the face hereof. 
 In connection with the issuance of the Securities of this series, the Corporation has entered into a Calculation Agent
Agreement dated as of September 21, 2020 (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). 

The Securities of this series are not redeemable at the option of the Corporation prior to March 14, 2021. On and after March 14,
2021, the Corporation may, at its option, redeem the Securities of this series, at any time in whole or from time to time in part, at a Redemption Price equal to 100% of the principal amount of the Securities of this series being redeemed, plus
accrued and unpaid interest on the Securities of this series being redeemed to the Redemption Date. 
 If the Corporation redeems Securities
of this series at its option, then, notwithstanding the foregoing, installments of interest on the Securities of this series that are due and payable on any Interest Payment Date falling on or prior to a Redemption Date for the Securities of this
series will be payable on that Interest Payment Date to the Holders thereof as of the close of business on the Regular Record Date immediately preceding such Interest Payment Date, according to the terms of the Securities of this series and the
Indenture. 
 The Corporation will mail notice of any redemption at least 30 days but not more than 60 days before the Redemption Date to
each Holder of the Securities of this series to be redeemed. Once notice of redemption is mailed, the Securities of this series called for redemption will become due and payable on the Redemption Date at the applicable Redemption Price, plus accrued
and unpaid interest to the Redemption Date, and will be paid upon surrender thereof for redemption. If the Corporation elects to redeem all or a portion of the Securities of this series, that redemption will not be conditional upon receipt by any
Paying Agent or the Trustee of monies sufficient to pay the Redemption Price. 
 Unless the Corporation defaults in payment of the
Redemption Price of any Securities of this series or portions thereof called for redemption, on and after the Redemption Date interest will cease to accrue on the Securities of this series or portions thereof called for redemption. 

If less than all of the Outstanding Securities of this series are to be redeemed on any Redemption Date, the particular Securities of this
series (or portions thereof) to be redeemed shall be selected by the Trustee by such method as the Trustee shall deem fair and appropriate or, in the case of Securities of this series represented by one or more Global Securities of this series
registered in the name of a Depositary or its nominee, by such method of selection as may be required or permitted by the procedures of the Depositary; provided that the unredeemed portion of the principal amount of any Security of this series shall
be an authorized denomination. In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor in an aggregate principal amount equal to the unredeemed portion of the principal hereof
will be issued in the name of the Holder hereof upon the cancellation hereof. 
 The Indenture contains provisions for defeasance of the
entire indebtedness of this Security and covenant defeasance with respect to the Securities of this series, in each case at any time 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. 

  
 Annex II-10 













 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 33% 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, the Trustee, for 60 days after its receipt of such notice, request and
offer of indemnity, has failed to institute any such proceeding, and no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in
principal amount of the Securities of this series at the time Outstanding. 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 any premium or interest hereon
on or after the respective due dates expressed herein. 
 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 premium, if any, 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 any premium and interest on this Security are payable. If this
Security is presented or surrendered for registration of transfer or exchange, it shall (if so required by the Corporation or the Trustee) be 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
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. 
 Prior to due presentment of this Security for registration
of transfer, the Corporation, the Trustee and any agent of the Corporation or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the
Corporation, the Trustee nor any such agent shall be affected by notice to the contrary. 
 This Security shall be governed by and construed
in accordance with the laws of the State of New York, without regard to conflict of law principles thereof. 
 All terms used in this
Security which are defined in the Indenture and not defined herein shall have the meanings assigned to them in the Indenture.
