THIS SIXTEENTH SUPPLEMENTAL INDENTURE (this “Sixteenth Supplemental Indenture”) is made as of the 18th day of October, 2018, 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 by this Sixteenth 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 modified, may be issued from time to time pursuant to the Indenture as at the time supplemented and modified, 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 Sixteenth 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

1.488% SENIOR NOTES DUE 2033

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 1.488% Senior Notes due 2033 (the “Senior Notes”).

There are to be authenticated and delivered Senior Notes, initially limited in aggregate principal amount to ¥15,200,000,000, 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 Sixteenth 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 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; provided that such additional Senior Notes are fungible for United States federal income tax purposes with any then-existing Senior Notes. 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 to 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.

“Business Day” means each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day in which banking institutions in the City of New York, Tokyo, or London are authorized and obligated by law, regulation or executive order to close.

“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 18 and October 18 of each year, commencing on April 18, 2019.

“Non-U.S. Holder” means a beneficial owner of a Senior Note (other than a partnership or other entity or arrangement treated as a partnership for United States federal income tax purposes) that is not a U.S. holder.

“Regular Record Date” means, with respect to each Interest Payment Date, the close of business on April 4 or October 4 immediately preceding such Interest Payment Date.

“Stated Maturity” means October 18, 2033.

Section 1.03 Payment of Principal and Interest. The principal of the Senior Notes shall be due at 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 1.488% 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 October 18, 2018. Interest shall be paid semi-annually in arrears on each Interest Payment Date, commencing on April 18, 2019, 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 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 Japanese yen. 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 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 ¥100,000,000 and integral multiples of ¥10,000,000 in excess thereof.

Section 1.05 Global Securities. The Senior Notes will initially be represented by one or more fully registered global notes. Each such Senior Note will be deposited with, or on behalf of, a common depositary, and registered in the name of the nominee of the common depositary for the accounts of Clearstream Banking, S.A. (“Clearstream”) and Euroclear Bank SA/NV (“Euroclear”). The Senior Notes may be held through Clearstream or Euroclear, either as a participant in such systems or indirectly through organizations which are participants in such systems. Clearstream and Euroclear will hold interests in the Senior Notes on behalf of their respective participating organizations or customers through customers’ securities accounts in Clearstream’s or Euroclear’s names on the books of their respective depositaries. Book-entry interests in the Senior Notes and all transfers relating to the Senior Notes will be reflected in the book-entry records of Clearstream and Euroclear.

Owners of beneficial interests in such Global Securities will not be entitled to have the Senior Notes registered in their names, will not receive or be entitled to receive physical delivery of the Senior Notes in definitive form and will not be considered the owners or holders of the notes under the Indenture, including for purposes of receiving any reports delivered by the Company or the Trustee pursuant to the Indenture. Accordingly, each person owning a beneficial interest in a Senior Note must rely on the procedures of the depositary and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, in order to exercise any rights of a holder of the Senior Notes.

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 Additional Amounts. All payments of principal and interest in respect of the Senior Notes will be made free and clear of, and without deduction or withholding for or on account of any present or future taxes, duties, assessments or other governmental charges of whatsoever nature imposed, levied, collected, withheld or assessed by the United States or any political subdivision or taxing authority of or in the United States (collectively, “Taxes”), unless such withholding or deduction is required by law.

In the event such withholding or deduction of Taxes is required by law, subject to the limitations described below, the Company will pay to any Non-U.S. Holder such additional amounts (“Additional Amounts”) as may be necessary in order that every net payment of principal of or interest on the Senior Notes (including upon redemption), after deduction or withholding for or on account of such Taxes, will not be less than the amount provided for in such Senior Notes to be then due and payable before deduction or withholding for or on account of such Taxes.

However, the Company’s obligation to pay Additional Amounts shall not apply to:

(a) any Taxes which would not have been so imposed, withheld or deducted but for:

(1) the existence of any present or former connection between such holder or beneficial owner (or between a fiduciary, settlor, beneficiary, member or shareholder or other equity owner of, or a person having a power over, such holder or beneficial owner, if such holder or beneficial owner is an estate, a trust, a limited liability company, a partnership, a corporation or other entity) and the United States, including, without limitation, such holder or beneficial owner (or such fiduciary, settlor, beneficiary, member, shareholder or other equity owner or person having such a power) being or having been a citizen or resident or treated as a resident of the United States or being or having been engaged in a trade or business in the United States or being or having been present in the United States or having or having had a permanent establishment in the United States;

(2) the failure of such holder or beneficial owner to comply with any applicable certification, information, documentation or other reporting requirement concerning the nationality, residence, identity or connection with the United States of such holder or beneficial owner or otherwise to establish entitlement to a partial or complete exemption from such Taxes (including, but not limited to, the requirement to provide Internal Revenue Service Form W-8BEN, Form W-8BEN-E, Form W-8ECI, or any subsequent versions thereof or successor thereto, and including, without limitation, any documentation requirement under an applicable income tax treaty); or

(3) such holder’s or beneficial owner’s present or former status as a personal holding company, foreign personal holding company, controlled foreign corporation, passive foreign investment company or foreign tax exempt organization with respect to the United States or as a corporation that accumulates earnings to avoid United States federal income tax;

(b) any Taxes imposed, withheld or deducted by reason of the holder or beneficial owner:

(1) owning or having owned, directly or indirectly, actually or constructively, 10% or more of the total combined voting power of all classes of the Company’s stock,

(2) being a bank receiving interest described in section 881(c)(3)(A) of the Internal Revenue Code, or

(3) being a controlled foreign corporation with respect to the United States that is related to the Company by stock ownership;

(c) any Taxes which would not have been so imposed, withheld or deducted but for the presentation by the holder or beneficial owner of Senior Note for payment on a date more than 10 days after the date on which such payment became due and payable or the date on which payment of the Senior Note is duly provided for and notice is given to holders, whichever occurs later, except to the extent that the holder or beneficial owner would have been entitled to such additional amounts on presenting such Senior Note on any date during such 10-day period;

(d) any estate, inheritance, gift, sales, transfer, capital gains, personal property, excise, wealth, interest equalization or similar Taxes;

(e) any Taxes which are payable otherwise than by withholding from any payment of principal of or interest on such Senior Note;

(f) any Taxes which are payable by a holder that is not the beneficial owner of the Senior Note, or a portion of the Senior Note, or that is a fiduciary, partnership, limited liability company or other similar entity, but only to the extent that a beneficial owner, a beneficiary or settlor with respect to such fiduciary or member of such partnership, limited liability company or similar entity would not have been entitled to the payment of an additional amount had such beneficial owner, settlor, beneficiary or member received directly its beneficial or distributive share of the payment;

(g) any Taxes required to be withheld by any paying agent from any payment of principal of or interest on any Senior Note, if such payment can be made without such withholding by any other paying agent;

(h) any Taxes that would not have been imposed, withheld or deducted but for a change in any law, treaty, regulation, or administrative or judicial interpretation that becomes effective after the applicable payment becomes due or is duly provided for, whichever occurs later, to the extent such change in law, treaty, regulation or administrative interpretation would apply retroactively to such payment;

(i) any Taxes imposed, withheld or deducted under Sections 1471 through 1474 of the Internal Revenue Code (or any amended or successor provisions that are substantively comparable) and any current or future regulations or official interpretations thereof (“FATCA”), any agreement (including any intergovernmental agreement) entered into in connection therewith, or any law, regulation or other official guidance enacted in any jurisdiction implementing FATCA or an intergovernmental agreement in respect of FATCA; or

(j) any combination of items (a), (b), (c), (d), (e), (f), (g), (h) and (i).

For purposes of this section, the acquisition, ownership, enforcement or holding of or the receipt of any payment with respect to a Senior Note will not constitute a connection (1) between the holder or beneficial owner and the United States or (2) between a fiduciary, settlor, beneficiary, member or shareholder or other equity owner of, or a person having a power over, such holder or beneficial owner if such holder or beneficial owner is an estate, a trust, a limited liability company, a partnership, a corporation or other entity and the United States.

Any reference in the Indenture or in the Senior Notes to principal or interest shall be deemed to refer also to Additional Amounts which may be payable under the provisions of this section.

Except as specifically provided in the Senior Notes, the Company will not be required to make any payment with respect to any tax, duty, assessment or other governmental charge imposed by any government or any political subdivision or taxing authority of or in any government or political subdivision.

Section 1.09 Tax Redemption. Except as provided below, the Senior Notes may not be redeemed prior to the Stated Maturity. Unless previously redeemed or repurchased and canceled, the Senior Notes will be repayable at par, including Additional Amounts, if any, on October 18, 2033, or such earlier date on which the same shall be due and payable in accordance with the terms and conditions of the notes. However, if the Stated Maturity is not a Business Day, the Senior Notes will be payable on the next succeeding Business Day and no interest shall accrue for the period from the Stated Maturity to such payment date.

The Senior Notes may be redeemed at the option of the Company, in whole but not in part, at a redemption price equal to 100% of the principal amount of the Senior Notes to be redeemed, together with interest accrued and unpaid on the Senior Notes to be redeemed to, but excluding, the date fixed for redemption, at any time, on giving not less than 30 nor more than 60 days’ notice if:

(a) the Company has or will become obligated to pay Additional Amounts as a result of any change in or amendment to the laws, regulations or rulings of the United States or any political subdivision or any taxing authority of or in the United States affecting taxation, or any change in or amendment to an official application, interpretation, administration or enforcement of such laws, regulations or rulings, which change or amendment is announced or becomes effective on or after October 12, 2018, or

However, no such notice of redemption shall be given earlier than 90 days prior to the earliest date on which the Company would be, in the case of a redemption for the reasons specified in (a) above, or there would be a substantial likelihood that the Company would be, in the case of a redemption for the reasons specified in (b) above, obligated to pay such Additional Amounts if a payment in respect of the notes were then due and at the time such notification of redemption is given such circumstance remains in effect.

Prior to the mailing of any notice of redemption pursuant to this section, the Company will deliver to the Trustee:

(1) a certificate signed by one of its duly authorized officers stating that the Company is entitled to effect such redemption and setting forth a statement of facts showing that the conditions precedent to the Company’s right so to redeem have occurred, and

(2) a written opinion of independent legal counsel of recognized standing to the effect that the Company has or will become obligated to pay such Additional Amounts as a result of such change or amendment or that there is a substantial likelihood that the Company will be required to pay such Additional Amounts as a result of such action or proposed change, clarification, amendment, application or interpretation, as the case may be.

Such notice, once delivered by the Company to the Trustee, will be irrevocable.

Section 1.10 Further Issues. The Company may from time to time, without notice to or the consent of the registered holders of Senior Notes, create and issue further notes ranking equally with the Senior Notes in all respects. Such further notes may be consolidated and form a single series with the Senior Notes and have the same terms as to status, redemption or otherwise as the notes (other than the issue date of such further notes and first payment of interest following the issue date of such further Senior Notes); provided that such additional Senior Notes are fungible for United States Federal income tax purposes with any then-existing Senior Notes.

The Securities represented by this Note are one of the series designated on the face hereof as 1.488% Senior Notes due 2033 (the “Senior Notes”), initially limited in aggregate principal amount to ¥15,200,000,000; 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 Sixteenth 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.

Except as provided below, the Senior Notes may not be redeemed prior to the Stated Maturity. Unless previously redeemed or repurchased and canceled, the Senior Notes will be repayable at par, including Additional Amounts, if any, on October 18, 2033, or such earlier date on which the same shall be due and payable in accordance with the terms and conditions of the notes.

Prior to the mailing of any notice of redemption pursuant to this section, the Company will deliver to the Trustee:

Such notice, once delivered by the Company to the Trustee, will be irrevocable.

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

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