THIS TWENTY-SEVENTH SUPPLEMENTAL INDENTURE (this “Twenty-Seventh Supplemental Indenture”) is made as of the 1st day of April, 2020, by and between AFLAC INCORPORATED, a Georgia corporation, as issuer (the “Company”), and THE BANK OF NEW YORK MELLON TRUST COMPANY, N.A., a national banking association, as trustee (the “Trustee”):

WHEREAS, the Company has heretofore entered into a Senior Indenture, dated as of May 21, 2009 (the “Original Indenture”), with the Trustee;

WHEREAS, the Original Indenture is incorporated herein by reference, and the Original Indenture, as supplemented and amended by this Twenty-Seventh Supplemental Indenture, is herein called the “Indenture”;

WHEREAS, under the Original Indenture, a new series of 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 amended, may be issued from time to time pursuant to the Indenture as at the time supplemented and amended, and all senior notes issued by the Company of any one series need not be issued at the same time and, unless otherwise so provided, may be reopened for issuances of additional senior notes of such series; and

WHEREAS, all things necessary to authorize the execution and delivery of this Twenty-Seventh Supplemental Indenture and make it a valid and binding agreement of the Company, in accordance with its terms, have been done.

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 I

3.600% SENIOR NOTES DUE 2030

Section 1.01. Establishment. There is hereby established a new series of senior notes to be issued under the Indenture, to be designated as the Company’s 3.600% Senior Notes due 2030 (the “Senior Notes”).

There are to be authenticated and delivered Senior Notes, initially limited in aggregate principal amount to $1,000,000,000 and no further Senior Notes shall be authenticated and delivered except as provided by Sections 2.8, 2.9, 2.11, 8.5 or 12.3 of the Original Indenture and the terms of this Twenth-Seventh Supplemental Indenture; provided, however, that the Company

may re-open this series of Senior Notes and the aggregate principal amount of the Senior Notes may be increased in the future, without the consent of the holders of the Senior Notes, with the same ranking, interest rate, maturity date and other terms and with the same CUSIP and ISIN numbers as the Senior Notes other than with respect to: (i) the date of issuance, (ii) the issue price and (iii) the date from which interest shall accrue and the amount of interest payable on the first Interest Payment Date (as defined below) following the issuance of any such additional Senior Notes (which terms shall be set forth in a Board Resolution accompanying the Order pursuant to which any such additional Senior Notes are authenticated). Any such additional Senior Notes and the Senior Notes established pursuant hereto shall be considered collectively as a single class for all purposes of the Indenture. The Senior Notes shall be issued in fully registered form.

The Senior Notes shall be issued in the form of one or more Global Securities (as defined below) in substantially the form set out in Exhibit A hereto.

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

Each Senior 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 on which interest has been paid or duly provided for.

Section 1.02. 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.

“Global Security” means, with respect to any series of securities, a security authenticated and delivered under the Original Indenture executed by the Company and held by the Trustee as custodian for the Depositary, all in accordance with the Original Indenture, which shall be registered in the name of the Depositary or its nominee.

“Interest Payment Date” means April 1 and October 1 of each year, commencing on October 1, 2020.

“Regular Record Date” means, with respect to each Interest Payment Date, the close of business on March 15 or September 15 immediately preceding such Interest Payment Date.

“Stated Maturity” means April 1, 2030.

Section 1.03. Payment of Principal and Interest. If not previously redeemed, the principal of the Senior Notes shall be due at the Stated Maturity. The unpaid and outstanding principal amount of the Senior Notes, and any overdue installment of interest thereon to the extent permitted by law, shall bear interest at the rate of 3.600% per year until paid or made available for payment, such interest to accrue from the most recent Interest Payment Date on which interest has been paid or duly provided for or, if no interest has been paid, from April 1, 2020. Interest shall be paid semi-annually in arrears on each Interest Payment Date, commencing on October 1, 2020 to the Person in whose name the Senior Notes are registered on

the Regular Record Date for such Interest Payment Date, provided that interest payable at the Stated Maturity or on a Redemption Date (as defined below) 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 be paid as provided in Section 2.7 of the Original Indenture.

Payments of interest on the Senior Notes will include interest accrued to but excluding the respective Interest Payment Dates. Interest payments for the Senior Notes shall be computed and paid on the basis of a 360-day year consisting of twelve 30-day months. In the event that any date on which interest is payable on the Senior Notes is not a Business Day, then payment of the interest payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay), except that, if such next succeeding Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on the date the payment was originally payable.

Payment of the principal, premium, if any, and interest due at the Stated Maturity of, or on a Redemption Date for, the Senior Notes shall be made upon surrender of the Senior Notes at the Corporate Trust Office of the Trustee. The principal of and interest on the Senior 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 an 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 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.

Section 1.04. Denominations. The Senior Notes will be issued only in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Section 1.05. Global Securities. The Senior Notes will initially be issued in the form of one or more Global Securities registered in the name of the Depositary (which initially shall be The Depository Trust Company (“DTC”)) or its nominee. Except under the limited circumstances described below, Senior Notes represented by Global Securities will not be exchangeable for, and will not otherwise be issuable as, Senior 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 Global Securities will not be considered the holders thereof for any purpose under the Indenture, and no Global Security representing a Senior 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 to a successor Depositary or its nominee. The rights of holders of such Global Securities shall be exercised only through the Depositary.

A Global Security shall be exchangeable for Senior Notes registered in the names of Persons other than the Depositary or its nominee only as provided by Section 2.8(5) of the Original Indenture. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Senior Notes registered in such names as the Depositary shall direct.

Section 1.06. Transfer. No service charge will be made for any registration of transfer or exchange of Senior 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.

Section 1.07. Defeasance. The provisions of Sections 10.4 and 10.5 of the Original Indenture will apply to the Senior Notes.

Section 1.08. Redemption at the Option of the Company. The Senior Notes will be redeemable, at the sole option of the Company, in whole at any time or in part from time to time (a “Redemption Date”), at a redemption price (the “Redemption Price”) as described below. The Redemption Price at any time prior to January 1, 2030 (three months prior to the maturity date of the Senior Notes) (a “Par Call Date”) will be equal to the greater of (i) 100% of the aggregate principal amount of the Senior Notes to be redeemed and (ii) an amount equal to the sum of the present values of the remaining scheduled payments for principal of and interest on the Senior Notes to be redeemed that would be due if the Senior Notes matured on the Par Call Date, not including any portion of the payments of interest accrued as of such Redemption Date, discounted to such Redemption 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, plus, in each case (i) and (ii), accrued and unpaid interest on the principal amount of the Senior Notes to be redeemed to, but excluding, such Redemption Date.

On or after the Par Call Date, the Redemption Price will be equal to 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon to the Redemption Date.

“Treasury Rate” means (i) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (as defined below) (if no maturity is within three months before or after the remaining life, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month), or (ii) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price (as defined below) for such Redemption Date. The Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date.

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker (as defined below) as having a maturity comparable to the remaining term of the Senior Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Senior Notes (assuming, for this purpose, that the Senior Notes matured on the Par Call Date).

“Independent Investment Banker” means one of Xxxxxxx Xxxxx & Co. LLC, Mizuho Securities USA LLC, Xxxxxx Xxxxxxx & Co. LLC, SMBC Nikko Securities America, Inc., and Xxxxx Fargo Securities, LLC and their successors, appointed by the Company or, if such firm is unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Company.

“Comparable Treasury Price” means with respect to any Redemption Date for the Senior Notes (1) the average of five Reference Treasury Dealer Quotations (as defined below) for such Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (2) if the Company obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations.

“Reference Treasury Dealer” means each of Xxxxxxx Xxxxx & Co. LLC, Mizuho Securities USA LLC, Xxxxxx Xxxxxxx & Co. LLC, Xxxxx Fargo Securities, LLC, and a primary U.S. government securities dealer (a “Primary Treasury Dealer”) selected by SMBC Nikko Securities America, Inc., and their respective successors; provided that if any of the foregoing or their respective successors shall cease to be a Primary Treasury Dealer, the Company will substitute therefor another Primary Treasury Dealer.

“Reference Treasury Dealer Quotations” means, with respect to the Reference Treasury Dealer and any Redemption Date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed, in each case, as a percentage of its principal amount) quoted in writing to the Independent Investment Banker by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date.

Notwithstanding Section 12.2 of the Original Indenture, the notice of redemption with respect to the foregoing redemption need not set forth the Redemption Price but only the manner of calculation thereof.

Section 1.09. Notice to Trustee. The Company shall notify the Trustee of the Redemption Price with respect to the foregoing redemption promptly after the calculation thereof. The Trustee shall not be responsible for calculating said Redemption Price.

Section 1.10. Selection of Senior Notes to be Redeemed; Notice of Redemption. If less than all of the Senior Notes are to be redeemed, the principal amount of such Senior Notes held by each beneficial owner of such Senior Notes to be redeemed shall be selected in accordance with the procedures of DTC. Senior Notes, and portions of Senior Notes, may be selected in amounts of $2,000 and whole multiples of $1,000 in excess thereof.

ARTICLE II

MISCELLANEOUS PROVISIONS

Section 2.01. Recitals by the Company. The recitals in this Twenty-Seventh Supplemental Indenture are made by the Company only and not by the Trustee, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Twenty-Seventh Supplemental Indenture or of the Senior Notes. The Trustee shall not be accountable for the use or application by the Company of the Senior Notes or the proceeds thereof. All of the provisions contained in the Original Indenture in respect of the rights, privileges, immunities, powers and duties of the Trustee shall be applicable in respect of the Senior Notes and of this Twenty-Seventh Supplemental Indenture as fully and with like effect as if set forth herein in full.

Section 2.02. Amendment to Sections 2.05 and 2.06 of the Original Indenture Relating to the Execution of Securities and the Certificate of Authentication. Sections 2.05 and 2.06 of the Original Indenture are amended and restated, with respect to the Senior Notes issued on the date hereof, to read as follows:

Section 2.5 Execution of Securities. The Securities and, if applicable, each Coupon appertaining thereto shall be signed on behalf of the Issuer by the chairman or vice chairman of its Board of Directors or its president or any executive, senior or other vice president or its treasurer, but need not, be attested. Such signatures may be the manual, facsimile or electronic signatures of the present or any future such officers. Typographical and other minor errors or defects in any such signature shall not affect the validity or enforceability of any Security that has been duly authenticated and delivered by the Trustee. In case any officer of the Issuer who shall have signed any of the Securities or Coupons, if any, shall cease to be such officer before the Security or Coupon so signed (or the Security to which the Coupon so signed appertains) shall be authenticated and delivered by the Trustee or disposed of by the Issuer, such Security or Coupon nevertheless may be authenticated and delivered or disposed of as though the person who signed such Security or Coupon had not ceased to be such officer of the Issuer; and any Security or Coupon may be signed on behalf of the Issuer by such persons as, at the actual date of the execution of such Security or Coupon, shall be the proper officers of the Issuer, although at the date of the execution and delivery of this Indenture any such person was not such an officer.

Section 2.6 Certificate of Authentication. Only such Securities as shall bear thereon a certificate of authentication substantially in the form herein before recited, executed by the Trustee by the manual, facsimile or electronic signature of one of its authorized signatories, shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. No Coupon shall be entitled to the benefits of this Indenture or shall be valid and obligatory for any purpose until the certificate of authentication on the Security to which such Coupon appertains shall have been duly executed by the Trustee. The execution of such certificate by the Trustee upon any Security executed by the Issuer shall be conclusive evidence that the Security so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this Indenture.

Section 2.03. Ratification and Incorporation of Original Indenture. As supplemented and amended hereby, the Original Indenture is in all respects ratified and confirmed, and the Original Indenture and this Twenty-Seventh Supplemental Indenture shall be read, taken and construed as one and the same instrument.

Section 2.04. Executed in Counterparts. This Twenty-Seventh Supplemental Indenture may be simultaneously executed in several counterparts, each of which shall be deemed to be an original, and such counterparts shall together constitute but one and the same instrument. The exchange of copies of this Twenty-Seventh Supplemental Indenture and of manual, facsimile or electronic signature pages shall constitute effective execution and delivery of this Supplemental Indenture as to the parties hereto.

Section 2.05. New York Law to Govern. This Twenty-Seventh Supplemental Indenture and each Senior Note shall be deemed to be a contract under the laws of the state of New York, and for all purposes shall be construed in accordance with the laws of such state, except as may be required by mandatory provisions of law.

IN WITNESS WHEREOF, each party hereto has caused this instrument to be signed in its name and behalf by its duly authorized officers, all as of the day and year first above written.

(Reverse Side of Note)

This note (the “Note”) represents one of a duly authorized issue of senior notes of the Company issued and issuable in one or more series under a Senior Indenture dated as of May 21, 2009 (the “Original Indenture”), as supplemented and amended by the Twenty-Seventh Supplemental Indenture dated as of April 1, 2020 (the “Twenty-Seventh Supplemental Indenture,” and together with the Original Indenture, the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A., as 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, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the holders of the Senior Notes (as defined below) issued thereunder and of the terms upon which said Senior Notes are, and are to be, authenticated and delivered. The Securities represented by this Note are one of the series designated on the face hereof as 3.600% Senior Notes due 2030 (the “Senior Notes”), initially limited in aggregate principal amount to $1,000,000,000; provided, however, that the aggregate principal amount of the Senior Notes may be increased in the future, without the consent of the holders of the Senior Notes, as provided in the Twenty-Seventh Supplemental Indenture. Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Indenture.

This Note is exchangeable in whole or from time to time in part for Senior Notes of this series in definitive registered form only as provided in the Indenture.

If an Event of Default with respect to the Senior Notes shall occur and be continuing, the principal of the Senior Notes 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 Senior Notes 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 aggregate principal amount of the Senior Notes at the time Outstanding. The Indenture also contains provisions permitting the holders of specified percentages in principal amount of the Senior Notes at the time Outstanding, on behalf of the holders of all Senior Notes, 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 Senior 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.

The Indenture contains provisions for defeasance at any time of (i) the entire indebtedness of the Company pursuant to this Note and (ii) restrictive covenants and the related Events of Default, upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Note.

A-6

The Senior Notes will be redeemable, at the sole option of the Company, in whole at any time or in part from time to time (a “Redemption Date”), at a redemption price (the “Redemption Price”) as described below. The Redemption Price at any time prior to January 1, 2030 (three months prior to the maturity date of the Senior Notes) (a “Par Call Date”) will be equal to the greater of (i) 100% of the aggregate principal amount of the Senior Notes to be redeemed and (ii) an amount equal to the sum of the present values of the remaining scheduled payments for principal of and interest on the Senior Notes to be redeemed that would be due if the Senior Notes matured on the Par Call Date, not including any portion of the payments of interest accrued as of such Redemption Date, discounted to such Redemption 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, plus, in each case, accrued and unpaid interest on the principal amount of the Senior Notes to be redeemed to, but excluding, such Redemption Date.

On or after the Par Call Date, the Redemption Price will be equal to 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon to the Redemption Date.

A-7

Notice of any redemption will be mailed at least 30 days but no more than 60 days before the Redemption Date to each holder of the Senior Notes to be redeemed. Notwithstanding Section 12.2 of the Original Indenture, the notice of redemption with respect to the foregoing redemption need not set forth the Redemption Price but only the manner of calculation thereof.

The Company shall notify the Trustee of the Redemption Price with respect to the foregoing redemption promptly after the calculation thereof. The Trustee shall not be responsible for calculating said Redemption Price. Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Senior Notes or portions thereof called for redemption.

If less than all of the Senior Notes are to be redeemed, the principal amount of such Senior Notes held by each beneficial owner of such Senior Notes to be redeemed shall be selected in accordance with the procedures of DTC. Senior Notes, and portions of Senior Notes, may be selected in amounts of $2,000 and whole multiples of $1,000 in excess thereof.
