THIS FOURTEENTH SUPPLEMENTAL INDENTURE is made as of the 27th day of March, 2018 by and between MISSISSIPPI POWER COMPANY, a Mississippi corporation, 2992 West Beach Boulevard, Gulfport, Mississippi 39501 (the “Company”), and WELLS FARGO BANK, NATIONAL ASSOCIATION, a national banking association, 150 East 42nd Street, 40th Floor, New York, New York 10017 (the “Trustee”).


W I T N E S S E T H:


WHEREAS, the Company has heretofore entered into a Senior Note Indenture, dated as of May 1, 1998 (the “Original Indenture”), with Wells Fargo Bank, National Association, as successor Trustee, as heretofore supplemented;


WHEREAS, the Original Indenture is incorporated herein by this reference and the Original Indenture, as heretofore supplemented and as further supplemented by this Fourteenth Supplemental Indenture, is herein called the “Indenture”;


WHEREAS, under the Original Indenture, a new series of unsecured senior debentures or notes or other evidence of indebtedness (the “Senior Notes”) may at any time be established by the Board of Directors of the Company in accordance with the provisions of the Original Indenture and the terms of such series may be described by a supplemental indenture executed by the Company and the Trustee;


WHEREAS, the Company proposes to create under the Indenture a new series of Senior Notes;


WHEREAS, additional Senior Notes of other series hereafter established, except as may be limited in the Original Indenture as at the time supplemented and modified, may be issued from time to time pursuant to the Indenture as at the time supplemented and modified; and


WHEREAS, all conditions necessary to authorize the execution and delivery of this Fourteenth Supplemental Indenture and to make it a valid and binding obligation of the Company have been done or performed.


NOW, THEREFORE, in consideration of the agreements and obligations set forth herein and for other good and valuable consideration, the sufficiency of which is hereby acknowledged, the parties hereto hereby agree as follows:















ARTICLE 1


Series 2018A Senior Notes




SECTION 101.  Establishment.  There is hereby established a new series of Senior Notes to be issued under the Indenture, to be designated as the Company’s Series 2018A Floating Rate Senior Notes due March 27, 2020 (the “Series 2018A Notes”).


There are to be authenticated and delivered $300,000,000 principal amount of Series 2018A Notes, and such principal amount of the Series 2018A Notes may be increased from time to time pursuant to Section 301 of the Original Indenture.  All Series 2018A Notes need not be issued at the same time and such series may be reopened at any time, without the consent of any Holder, for issuances of additional Series 2018A Notes.  Any such additional Series 2018A Notes will have the same interest rate, maturity and other terms as those initially issued (except for the public offering price and issue date and initial interest accrual date and initial Interest Payment Date (as defined below), if applicable).  No Series 2018A Notes shall be authenticated and delivered in excess of the principal amount as so increased except as provided by Sections 203, 303, 304, 907 or 1107 of the Original Indenture.  The Series 2018A Notes shall be issued in fully registered form.


The Series 2018A Notes shall be issued in the form of one or more Global Securities in substantially the form set out in Exhibit A hereto.  The Depositary with respect to the Series 2018A Notes shall be The Depository Trust Company.


The form of the Trustee’s Certificate of Authentication for the Series 2018A Notes shall be in substantially the form set forth in Exhibit B hereto.


Each Series 2018A Note shall be dated the date of authentication thereof and shall bear interest from the date of original issuance thereof or from the most recent Interest Payment Date to which interest has been paid or duly provided for.


The Series 2018A Notes will not have a sinking fund.


SECTION 102.  Definitions.  The following defined terms used herein shall, unless the context otherwise requires, have the meanings specified below.  Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Original Indenture.


“Calculation Agent” means Wells Fargo Bank, National Association, or its successor appointed by the Company, acting as calculation agent.
“Interest Determination Date” means the second London Business Day immediately preceding the first day of the relevant Interest Period.
“Interest Payment Dates” means the 27th day of March, June, September and December, commencing June 27, 2018; provided, however, in the event that any Interest Payment Date (other 


2







than the Interest Payment Date that is the Stated Maturity) would otherwise be a day that is not a Business Day, the Interest Payment Date will be the next succeeding Business Day.
“Interest Period” means the period commencing on an Interest Payment Date (or, with respect to the initial Interest Period only, commencing on the Original Issue Date) and ending on the day before the next succeeding Interest Payment Date.
“London Business Day” means a day that is a Business Day and a day on which dealings in deposits in U.S. dollars are transacted, or with respect to any future date are expected to be transacted, in the London interbank market.
“Original Issue Date” means March 27, 2018.
“Regular Record Date” means, with respect to each Interest Payment Date, the 15th calendar day preceding such Interest Payment Date (whether or not a Business Day).
“Reuters LIBOR01 Page” means the display designated as Reuters LIBOR01 on the Reuters service (or such other page as may replace the Reuters LIBOR01 Page on that service, or such other service as may be nominated as the information vendor, for the purpose of displaying rates or prices comparable to the London Interbank Offered rate for U.S. dollar deposits).
“Stated Maturity” means March 27, 2020; provided that if the Stated Maturity is not a Business Day, the principal and interest due on that date will be payable on the next succeeding Business Day, and no interest shall accrue for the intervening period; provided, further, that if such next succeeding Business Day is in the next succeeding calendar year, such payment will be made on the immediately preceding Business Day.
“Three-Month LIBOR” means, with respect to any Interest Period, the rate (expressed as a percentage per annum) for deposits in U.S. dollars having an index maturity of three months that appears on the Reuters LIBOR01 Page as of 11:00 a.m. (London time) on the Interest Determination Date for that Interest Period. If such rate does not appear on the Reuters LIBOR01 Page as of 11:00 a.m. (London time) on the Interest Determination Date for that Interest Period, Three-Month LIBOR will be determined on the basis of the rates at which deposits in U.S. dollars for the Interest Period and in a principal amount of not less than $1,000,000 are offered to prime banks in the London interbank market by four major banks in the London interbank market (which may include affiliates of one or more of the underwriters of the Series 2018A Notes) selected by the Company, at approximately 11:00 a.m., London time, on the Interest Determination Date for that Interest Period. The Calculation Agent will request the principal London office of each such bank to provide a quotation of its rate. If at least two such quotations are provided, Three-Month LIBOR with respect to that Interest Period will be the arithmetic mean of such quotations. If fewer than two quotations are provided, Three-Month LIBOR with respect to that Interest Period will be the arithmetic mean of the rates quoted by three major banks in New York City (which may include affiliates of one or more of the underwriters of the Series 2018A Notes) selected by the Company, at approximately 11:00 a.m., New York City time, on the Interest Determination Date for that Interest Period for loans in U.S. dollars to leading European banks for that Interest Period and in a principal amount of not less than $1,000,000. However, if fewer than three banks selected by the Company to provide quotations are quoting as described above, Three-Month LIBOR for that Interest Period will be the same as the rate determined for the previous Interest Period.


3









SECTION 103.  Payment of Principal and Interest.  The principal of the Series 2018A Notes shall be due at Stated Maturity (unless earlier redeemed).  The unpaid principal amount of the Series 2018A Notes shall bear interest at the rates set quarterly pursuant to Section 104 hereof until paid or duly provided for.  Interest shall be paid quarterly in arrears on each Interest Payment Date to the Person in whose name the Series 2018A Notes are registered at the close of business on the Regular Record Date for such Interest Payment Date, provided that interest payable at the Stated Maturity or on a Redemption Date as provided herein will be paid to the Person to whom principal is payable.  Any such interest that is not so punctually paid or duly provided for will forthwith cease to be payable to the Holders on such Regular Record Date and may either be paid to the Person or Persons in whose name the Series 2018A Notes are 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 the Series 2018A Notes not less than ten (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, if any, on which the Series 2018A Notes shall be listed, and upon such notice as may be required by any such exchange, all as more fully provided in the Original Indenture.


Payments of interest on the Series 2018A Notes will include interest accrued to but excluding the respective Interest Payment Dates.  Interest payments for the Series 2018A Notes shall be computed and paid on the basis of the actual number of days elapsed over a 360-day year.


Payment of the principal and interest due at the Stated Maturity or earlier redemption of the Series 2018A Notes shall be made upon surrender of the Series 2018A Notes at the Corporate Trust Office of the Trustee.  The principal of and interest on the Series 2018A Notes shall be paid 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.  Payments of interest (including interest on any Interest Payment Date) will be made, subject to such surrender where applicable, at the option of the Company, (i) by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or (ii) by wire transfer or other electronic 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 sixteen (16) days prior to the date for payment by the Person entitled thereto.


SECTION 104.    Determination of Interest. The Series 2018A Notes will bear interest for each Interest Period at a per annum rate determined by the Calculation Agent, subject to the maximum interest rate permitted by New York or other applicable state law, as such law may be modified by United States law of general application. The interest rate applicable during each Interest Period will be equal to Three-Month LIBOR on the Interest Determination Date for such Interest Period plus 0.65%. In no event shall the applicable interest rate be less than 0% for any Interest Period. Promptly upon such determination, the Calculation Agent will notify the Company and the Trustee, if the Trustee is not then serving as the Calculation Agent, of the interest rate for the new Interest Period. The interest rate determined by the Calculation Agent, absent manifest error, shall be binding and conclusive upon the beneficial owners and Holders of the Series 2018A Notes, the Company and the Trustee.




4







Upon the request of a Holder of the Series 2018A Notes, the Calculation Agent will provide to such Holder the interest rate in effect on the date of such request and, if determined, the interest rate for the next Interest Period.


SECTION 105.  Denominations.  The Series 2018A Notes may be issued in denominations of $2,000 and integral multiples of $1,000 in excess thereof.


SECTION 106.  Global Securities.  The Series 2018A Notes will be issued in the form of one or more Global Securities registered in the name of the Depositary (which shall be The Depository Trust Company) or its nominee.  Except under the limited circumstances described below, Series 2018A Notes represented by one or more Global Securities will not be exchangeable for, and will not otherwise be issuable as, Series 2018A Notes in definitive form.  The Global Securities described above may not be transferred except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or to a successor Depositary or its nominee.


Owners of beneficial interests in such a Global Security will not be considered the Holders thereof for any purpose under the Indenture, and no Global Security representing a Series 2018A Note shall be exchangeable, except for another Global Security of like denomination and tenor to be registered in the name of the Depositary or its nominee or a successor Depositary or its nominee.  The rights of Holders of such Global Security shall be exercised only through the Depositary.


Subject to the procedures of the Depositary, a Global Security shall be exchangeable for Series 2018A Notes registered in the names of persons other than the Depositary or its nominee only if (i) the Depositary notifies the Company that it is unwilling or unable to continue as a Depositary for such Global Security and no successor Depositary shall have been appointed by the Company, or if at any time the Depositary ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, at a time when the Depositary is required to be so registered to act as such Depositary and no successor Depositary shall have been appointed by the Company, in each case within 90 days after the Company receives such notice or becomes aware of such cessation, (ii) the Company in its sole discretion determines that such Global Security shall be so exchangeable, or (iii) there shall have occurred an Event of Default with respect to the Series 2018A Notes.  Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Series 2018A Notes registered in such names as the Depositary shall direct.


Neither the Company, the Trustee nor any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.


SECTION 107.  Transfer.  No service charge will be made for any transfer or exchange of Series 2018A Notes, but payment will be required of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.  The Company shall not be required (a) to issue, register the transfer of or exchange any Series 2018A Notes during a period beginning at the opening of business fifteen (15) days before the day of the mailing of a notice 


5







pursuant to Section 1104 of the Original Indenture identifying the serial numbers of the Series 2018A Notes to be called for redemption, and ending at the close of business on the day of the mailing, or (b) to register the transfer of or exchange any Series 2018A Notes theretofore selected for redemption in whole or in part, except the unredeemed portion of any Series 2018A Notes redeemed in part.


SECTION 108.  Redemption at the Company’s Option.  At any time and from time to time on or after September 27, 2018, the Series 2018A Notes will be subject to redemption at the option of the Company, in whole or in part, upon not less than 30 nor more than 60 days’ notice, at a Redemption Price equal to 100% of the principal amount of the Series 2018A Notes being redeemed plus accrued and unpaid interest thereon to the Redemption Date.


If the Redemption Date is not a Business Day, the principal and interest due on that date will be payable on the next succeeding Business Day, and no interest shall accrue for the intervening period; provided, however, that if such next succeeding Business Day is in the next succeeding calendar year, such payment will be made on the immediately preceding Business Day.


In the event of redemption of the Series 2018A Notes in part only, a new Series 2018A Note or Notes for the unredeemed portion will be issued in the name or names of the Holders thereof upon the surrender thereof.


Notice of redemption shall be given as provided in Section 1104 of the Original Indenture.


Any redemption of less than all of the Series 2018A Notes shall, with respect to the principal thereof, be divisible by $1,000.

The Series 2018A Notes (as defined on the reverse hereof) will bear interest for each Interest Period at a per annum rate determined by the Calculation Agent, subject to the maximum interest rate permitted by New York or other applicable state law, as such law may be modified by United States law of general application.

If such rate does not appear on the Reuters LIBOR01 Page as of 11:00 a.m. (London time) on the Interest Determination Date for that Interest Period, Three-Month LIBOR will be determined on the basis of the rates at which deposits in U.S. dollars for the Interest Period and in a principal amount of not less than $1,000,000 are offered to prime banks in the London interbank market by four major banks in the London interbank market (which may include affiliates of one or more of the underwriters of the Series 2018A Notes) selected by the Company, at approximately 11:00 a.m., London time, on the Interest Determination Date for that Interest Period.

However, if fewer than three banks selected by the Company to provide quotations are quoting as described above, Three-Month LIBOR for that Interest Period will be the same as the rate determined for the previous Interest Period.


Payments of interest on this Note will include interest accrued to but excluding the respective Interest Payment Dates.  Interest payments for this Note shall be computed and paid on the basis of the actual number of days elapsed over a 360-day year.

This Note is one of a duly authorized issue of Senior Notes of the Company (the “Notes”), issued and issuable in one or more series under a Senior Note Indenture, dated as of May 1, 1998, as supplemented (the “Indenture”), between the Company and Wells Fargo Bank, National Association, as successor Trustee (the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures incidental thereto reference is hereby made for a statement of the respective rights, limitation of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes issued thereunder and of the terms upon which said Notes are, and are to be, authenticated and delivered.  This Note is one of the series designated on the face hereof as Series 2018A Floating Rate Senior Notes due March 27, 2020 (the “Series 2018A Notes”) which is unlimited in aggregate principal amount.  Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Indenture.


At any time and from time to time on or after September 27, 2018, the Series 2018A Notes will be subject to redemption at the option of the Company, in whole or in part, upon not less than 30 nor more than 60 days’ notice, at a Redemption Price equal to 100% of the principal amount of the Series 2018A Notes being redeemed plus accrued and unpaid interest thereon to the Redemption Date.


If the Redemption Date is not a Business Day, the principal and interest due on that date will be payable on the next succeeding Business Day, and no interest shall accrue for the intervening period; provided, however, that if such next succeeding Business Day is in the next succeeding calendar year, such payment will be made on the immediately preceding Business Day.


In the event of redemption of this Note in part only, a new Note or Notes of this series for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the surrender hereof.  The Series 2018A Notes will not have a sinking fund.


If an Event of Default with respect to the Notes of this series shall occur and be continuing, the principal of the Notes of this series may be declared due and payable in the manner, with the effect and subject to the conditions 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 Company and the rights of the Holders of the Notes of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of the Notes at the time Outstanding of each series to be affected.  The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Notes of each series at the time Outstanding, on behalf of the Holders of all Notes of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences.  Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.
