*Private Placement of Senior Notes* 

On May 29, 2025, Aflac Incorporated, a Georgia corporation (the "Company"), entered into a Note Purchase Agreement with the purchasers named therein (the "Purchase Agreement") in connection with the offer and sale in a private placement of an aggregate principal amount of ¥75,100,000,000 of the Company's yen-denominated senior notes (the "Private Placement Notes"). The Private Placement Notes consist of (a) ¥18,200,000,000 aggregate principal amount of the Company's 1.990% Senior Notes, Series A, due 2032, (b) ¥38,300,000,000 aggregate principal amount of the Company's 2.320% Senior Notes, Series B, due 2035, (c) ¥11,600,000,000 aggregate principal amount of the Company's 2.650% Senior Notes, Series C, due 2040, and (d) ¥7,000,000,000 aggregate principal amount of the Company's 3.040% Senior Notes, Series D, due 2045.

The Private Placement Notes bear interest on the outstanding principal balance at the stated rates per annum from the date of issuance, payable semiannually on May 29 and November 29 of each year, commencing November 29, 2025, until such principal becomes due and payable. The Private Placement Notes are senior unsecured obligations of the Company and rank at least pari passu in right of payment with all other unsecured senior indebtedness of the Company.

The Purchase Agreement contains customary covenants, events of default, prepayment and other standard terms and conditions, many of which are consistent with terms and conditions of the Company's other obligations, including under its existing credit facility.

The Company intends to use the net proceeds from the issuance of the Private Placement Notes for general corporate purposes. The Private Placement Notes have not been registered under the Securities Act of 1933, as amended (the "Securities Act"), and were offered and sold in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act.

*Registered Senior Notes Offering*

On June 5, 2025, the Company issued (i) ¥35,000,000,000 aggregate principal amount of 1.726% Senior Notes due 2030 (the "2030 Notes"), (ii) ¥23,400,000,000 aggregate principal amount of 2.003% Senior Notes due 2032 (the "2032 Notes"), (iii) ¥9,500,000,000 aggregate principal amount of 2.369% Senior Notes due 2035 (the "2035 Notes") and (iv) ¥7,000,000,000 aggregate principal amount of 2.779% Senior Notes due 2040 (the "2040 Notes" and, together with the 2030 Notes, the 2032 Notes and the 2035 Notes, the "Registered Notes"). The Registered Notes were offered by the Company in a public offering pursuant to the Company's Registration Statement on Form S-3ASR (No. 333-281977) (the "Registration Statement"), the prospectus dated September 6, 2024, and the related prospectus supplement dated May 30, 2025. The Company intends to use the net proceeds from the offering of Registered Notes for general corporate purposes.

The sale of the Registered Notes was made pursuant to the terms of an underwriting agreement, dated May 30, 2025 (the "Underwriting Agreement"), by and among the Company and the several underwriters included on Schedule I thereto, for whom Mizuho Securities USA LLC, Morgan Stanley & Co. International plc and SMBC Nikko Securities America, Inc. acted as representatives. The Underwriting Agreement contains customary terms, conditions, representations and warranties and indemnification provisions.

The 2030 Notes bear interest at the rate of 1.726% per annum from and including their date of issuance to, but excluding, October 18, 2030, or early redemption. The 2032 Notes bear interest at the rate of 2.003% per annum from and including their date of issuance to, but excluding, December 14, 2032, or early redemption. The 2035 Notes bear interest at the rate of 2.369% per annum from and including their date of issuance to, but excluding, June 5, 2035, or early redemption. The 2040 Notes bear interest at the rate of 2.779% per annum from and including their date of issuance to, but excluding, June 5, 2040, or early redemption. Interest on the Registered Notes is payable semi-annually in arrears on June 5 and December 5 each year, beginning on December 5, 2025, except that the final interest payment dates, in the case of the 2030 Notes and the 2032 Notes, shall be the respective maturity dates of the 2030 Notes (short last coupon) and the 2032 Notes (long last coupon). On or after the date that is three months, in the case of the 2030 Notes and the 2032 Notes, and six months, in the case of the 2035 Notes and the 2040 Notes, prior to their respective maturity date, the applicable series of Registered Notes will be redeemable in whole or in part from time to time, at the sole option of the Company, at a redemption price equal to 100% of the aggregate principal amount of the applicable series of Registered Notes to be redeemed plus accrued and unpaid interest on the principal amount of the Registered Notes to be redeemed, if any, to, but not including, the redemption date.

The Registered Notes are general unsecured obligations and rank equally in right of payment with any of the Company's existing and future unsecured senior indebtedness. The Registered Notes were issued under an indenture, dated as of May 21, 2009 (the "Base Indenture"), between the Company, as issuer, and The Bank of New York Mellon Trust Company, N.A., as trustee (the "Trustee"), as supplemented by (i) a forty-first supplemental indenture, dated as of June 5, 2025 (the "Forty-First Supplemental Indenture"), between the Company and the Trustee, in the case of the 2030 Notes, (ii) a forty-second supplemental indenture, dated as of June 5, 2025 (the "Forty-Second Supplemental Indenture"), between the Company and the Trustee, in the case of the 2032 Notes, (iii) a forty-third supplemental indenture, dated as of June 5, 2025 (the "Forty-Third Supplemental Indenture"), between the Company and the Trustee, in the case of the 2035 Notes, and (iv) a forty-fourth supplemental indenture, dated as of June 5, 2025 (the "Forty-Fourth Supplemental Indenture"), between the Company and the Trustee, in the case of the 2040 Notes. As used herein, the term "Indenture" means the Base Indenture as supplemented by, (1) in the case of the 2030 Notes, the Forty-First Supplemental Indenture, (2) in the case of the 2032 Notes, the Forty-Second Supplemental Indenture, (3) in the case of the 2035 Notes, the Forty-Third Supplemental Indenture and, (4) in the case of the 2040 Notes, the Forty-Fourth Supplemental Indenture. The Indenture provides for customary events of default, including, among other things, nonpayment, failure to comply with the other agreements in the Indenture for a period of 90 days, and certain events of bankruptcy, insolvency and reorganization.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) To pay the required Commission filing fees relating to the Securities within the time required by Rule 456(b)(1) under the Act without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) under the Act;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) To use the net proceeds received by it from the sale of the Securities pursuant to this Agreement in the manner specified in the Pricing Prospectus under the caption "Use of Proceeds"; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) Upon request of any Underwriter, to furnish, or cause to be furnished, to such Underwriter an electronic version of the Company's trademarks, servicemarks and corporate logo for use on the website, if any, operated by such Underwriter for the purpose of facilitating the on-line offering of the Securities (the "License"); *provided, however*, that the License shall be used solely for the purpose described above, is granted without any fee and may not be assigned or transferred.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Company represents and agrees that, other than the final term sheet prepared and filed pursuant to Section 5(a) hereof, without the prior consent of the Representatives, it has not made and will not make any offer relating to the Securities that would constitute a "free writing prospectus" as defined in Rule 405 under the Act; each Underwriter represents and agrees that, without the prior consent of the Company and the Representatives, other than one or more term sheets relating to the Securities containing customary information and conveyed to purchasers of Securities, it has not made and will not make any offer relating to the Securities that would constitute a free writing prospectus; and any such free writing prospectus the use of which has been consented to by the Company and the Representatives (including the final term sheet prepared and filed pursuant to Section 5(a) hereof) is listed on Schedule II(a) hereto. The Company also consents to the use by any Underwriter of a free writing prospectus that (A) is not an "issuer free writing prospectus" as defined in Rule 433 and (B) contains only (i) information describing the preliminary terms of the Securities or their offering, (ii) information that describes the final terms of the Securities or their offering and that is included in the final term sheet contemplated in Section 5(a) hereof or (iii) contains comparable bond price or similar information that (in the case of this clause (iii) only) is not "issuer information," as defined in Rule 433;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Company has complied and will comply with the requirements of Rule 433 under the Act applicable to any Issuer Free Writing Prospectus, including timely filing with the Commission or retention where required and legending; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Company agrees that if at any time following issuance of an Issuer Free Writing Prospectus any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would conflict with the information in the Registration Statement, the Pricing Prospectus or the Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing, not misleading, the Company will give prompt notice thereof to the Representatives and, if requested by the Representatives, will prepare and furnish without charge to each Underwriter an Issuer Free Writing Prospectus or other document which will correct such conflict, statement or omission; *provided*, *however*, that this representation and warranty shall not apply to any statements or omissions in an Issuer Free Writing Prospectus made in reliance upon and in conformity with information furnished in writing to the Company by an Underwriter through the Representatives expressly for use therein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. The Company covenants and agrees with the several Underwriters that the Company will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Company's counsel and accountants in connection with the registration of the Securities under the Act and all other expenses in connection with the preparation, printing, reproduction and filing of the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, any Issuer Free Writing Prospectus and the Prospectus and amendments and supplements thereto and the mailing and delivering of copies thereof to the Underwriters and dealers; (ii) the cost of printing or producing any agreement among Underwriters, this Agreement, the Indenture, the Blue Sky Memorandum, closing documents (including any compilations thereof) and any other documents in connection with the offering, purchase, sale and delivery of the Securities; (iii) all expenses in connection with the qualification of the Securities for offering and sale under state securities laws as provided in Section 5(d) hereof, including the fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky survey; (iv) any fees charged by securities rating services for rating the Securities; (v) the cost of preparing the Securities; (vi) the fees and expenses of the Trustee and any agent of the Trustee and the fees and disbursements of counsel for the Trustee in connection with the Indenture and the Securities; and (vii) all other costs and expenses incident to the performance of its obligations hereunder which are not otherwise specifically provided for in this Section. It is understood, however, that, except as provided in this Section, and Sections 11 and 14 hereof, the Underwriters will pay all of their own costs and expenses, including the fees of their counsel, transfer taxes on resale of any of the Securities by them, and any advertising expenses connected with any offers they may make, pro rata (based on the principal amount of the Securities that such Underwriter agreed to purchase hereunder, as set out in Schedule I).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. The parties hereto confirm the appointment of Mizuho Securities USA LLC as stabilising manager (the "Stabilising Manager") as the central point responsible for public disclosure regarding stabilisation of the information and handling any competent authority requests, in each case in accordance with Commission Delegated Regulation (EU) 2016/1052 of 8 March 2016 and the UK FCA Stabilisation Binding Technical Standards, as applicable. The Stabilising Manager (or persons acting on behalf of the Stabilising Manager) may, to the extent permitted by applicable laws and directives, over-allot or effect transactions with a view to supporting the market price of the Securities at a level higher than that which might otherwise prevail, but in doing so the Stabilising Manager shall act as principal and not as agent of the Company and any loss resulting from overallotment and stabilisation shall be borne, and any profit arising therefrom shall be beneficially retained, by the Stabilising Manager. However, there is no assurance that the Stabilising Manager (or persons acting on behalf of the Stabilising Manager) will undertake any stabilisation action. Any stabilisation action may begin on or after the date on which adequate public disclosure of the terms of the Securities is made and, if begun, may cease at any time, but it must end no later than the earlier of 30 days after the issue date of the Securities and 60 days after the date of the allotment of the Securities. Such stabilisation shall be conducted by the Stabilising Manager in accordance with all applicable laws, regulations and rules. Nothing contained in this paragraph shall be construed so as to require the Company to issue in excess of the aggregate principal amount of Securities specified in Schedule I hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. Mizuho Securities USA LLC or such other Underwriter as the Underwriters may agree to settle the Securities (the "Settlement Bank") acknowledges that the Securities will initially be credited to an account (the "Commissionaire Account") for the benefit of the Settlement Bank, the terms of which Commissionaire Account include a third-party beneficiary clause ('*stipulation pour autrui*') with the Company as the third-party beneficiary and provide that such Securities are to be delivered to others only against payment of the net subscription monies for the Securities (*i*.*e*., less the commissions and expenses to be deducted from the subscription monies, with any transfer taxes payable in connection with the sale of the Securities duly paid, without duplication, by the Company) into the Commissionaire Account on a delivery against payment basis. The Settlement Bank acknowledges that (i) the Securities shall be held to the order of the Company as set out above and (ii) the net subscription monies for the Securities received in the Commissionaire Account (*i*.*e*., less the commissions and expenses deducted from the subscription monies) will be held on behalf of the Company until such time as they are transferred to the Company's order. The Settlement Bank undertakes that the net subscription monies for the Securities (*i*.*e*., less the commissions and expenses deducted from the subscription monies) will be transferred to the Company's order promptly following receipt of such monies in the Commissionaire Account. The Company acknowledges and accepts the benefit of the third-party beneficiary clause ('*stipulation pour autrui*') pursuant to the Belgian or Luxembourg Civil Code, as applicable, in respect of the Commissionaire Account.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. The obligations of the Underwriters hereunder shall be subject, in their discretion, to the condition that all representations and warranties and other statements of the Company herein are, at and as of the Closing Date, true and correct, the condition that the Company shall have performed all of its obligations hereunder theretofore to be performed, and the following additional conditions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) (i) The Prospectus shall have been filed with the Commission pursuant to Rule 424(b) under the Act within the applicable time period prescribed for such filing by the rules and regulations under the Act and in accordance with Section 5(a) hereof; (ii) the final term sheet contemplated by Section 5(a) hereof, and any other material required to be filed by the Company pursuant to Rule 433(d) under the Act, shall have been filed with the Commission within the applicable time periods prescribed for such filings by Rule 433; (iii) no stop order suspending the effectiveness of the Registration Statement or any part thereof shall have been issued and no proceeding for that purpose shall have been initiated or threatened by the Commission and no notice of objection of the Commission to the use of the Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Act shall have been received; (iv) no stop order suspending or preventing the use of the Prospectus or any Issuer Free Writing Prospectus shall have been initiated or threatened by the Commission; and (v) all requests for additional information on the part of the Commission shall have been complied with to the reasonable satisfaction of the Representatives;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Sullivan & Cromwell LLP, counsel for the Underwriters, shall have furnished to the Representatives such written opinion or opinions, dated the Closing Date, with respect to such matters as the Representatives may reasonably request, and such counsel shall have received such papers and information as they may reasonably request to enable them to pass upon such matters;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Sidley Austin LLP, counsel for the Company, shall have furnished to the Representatives their written opinion (a draft of such opinion is attached hereto as Annex II), dated the Closing Date, in a form and substance satisfactory to the Representatives.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Audrey Boone Tillman, Esq., Senior Executive Vice President and General Counsel of the Company, shall have furnished to the Representatives her written opinion (a draft of such opinion is attached hereto as Annex III), dated the Closing Date, in form and substance satisfactory to the Representatives.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) On the date hereof, on the effective date of any post-effective amendment to the Registration Statement filed subsequent to the date of this Agreement and also on the Closing Date, KPMG LLP shall have furnished to the Representatives a letter or letters, dated the respective dates of delivery thereof, in form and substance satisfactory to the Representatives, to the effect set forth in Annex I hereto (the form of letter to be delivered on the date hereof is attached as Annex I-A hereto). On the date hereof, on the effective date of any post-effective amendment to the Registration Statement filed subsequent to the date of this Agreement and also on the Closing Date, Max K. Brodén, Senior Executive Vice President and Chief Financial Officer of the Company, shall have furnished to the Representatives a certificate or certificates, dated the respective dates of delivery thereof, in form and substance satisfactory to the Representatives, to the effect set forth in Annex I hereto (the form of certificate to be delivered on the date hereof is attached as Annex I-B hereto and the form of certificate to be delivered on the effective date of any post-effective amendment to the Registration Statement and as of the Closing Date is attached as Annex I-C hereto).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) (i) Neither the Company nor any of its subsidiaries shall have sustained since the date of the latest audited financial statements included or incorporated by reference in the Pricing Prospectus any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Pricing Prospectus, and (ii) since the respective dates as of which information is given in the Pricing Prospectus there shall not have been any change in the capital stock or long-term debt of the Company or any of its subsidiaries or any change, or any development involving a prospective change, in or affecting the general affairs, management, financial position, shareholders' equity or results of operations of the Company and its subsidiaries, otherwise than as set forth or contemplated in the Pricing Prospectus, the effect of which, in any such case described in clause (i) or (ii), is in the judgment of the Representatives so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities on the terms and in the manner contemplated in the Prospectus;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) On or after the Applicable Time (i) no downgrading shall have occurred in the rating accorded the Company's debt securities or the Company's financial strength or claims paying ability by any "nationally recognized statistical rating organization," as that term is defined by the Commission under Section 3 of the Exchange Act, and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Company's debt securities or the Company's financial strength or claims paying ability;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) On or after the Applicable Time there shall not have occurred any of the following: (i) a suspension or material limitation in trading in securities generally on the New York Stock Exchange or on the Tokyo Stock Exchange; (ii) a suspension or material limitation in trading in the Company's securities on the New York Stock Exchange or the Tokyo Stock Exchange; (iii) a general moratorium on commercial banking activities declared by either Federal or New York State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States or Japan or with respect to the Clearstream or Euroclear systems in Europe; (iv) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war, or (v) the occurrence of any other calamity or crisis (including without limitation as a result of an epidemic or pandemic) or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (iv) or (v) in the judgment of the Representatives makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities on the terms and in the manner contemplated in the Prospectus;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) The Company shall have complied with the provisions of Section 5(e) hereof with respect to the furnishing of prospectuses on the New York Business Day next succeeding the date of this Agreement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) The Company shall have furnished or caused to be furnished to the Representatives on the Closing Date certificates of officers of the Company satisfactory to the Representatives as to the accuracy of the representations and warranties of the Company herein at and as of such time, as to the performance by the Company of all of its obligations hereunder to be performed at or prior to such time, as to the matters set forth in subsections (a) and (f) of this Section and as to such other matters as the Representatives may reasonably request.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Company will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any "issuer information" filed or required to be filed pursuant to Rule 433(d) under the Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; *provided*, *however*, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use therein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Each Underwriter will, severally and not jointly, indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus or any such amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use therein; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) If the indemnification provided for in this Section 11 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriters on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The obligations of the Company under this Section 11 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of any Underwriter and to each person, if any, who controls any Underwriter within the meaning of the Act and each broker-dealer affiliate of any Underwriter; and the obligations of the Underwriters under this Section 11 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Act.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) If any Underwriter shall default in its obligation to purchase the Securities which it has agreed to purchase hereunder, the Representatives may in your discretion arrange for you or another party or other parties to purchase such Securities on the terms contained herein. If within thirty six hours after such default by any Underwriter the Representatives do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of thirty six hours within which to procure another party or other parties satisfactory to the Representatives to purchase such Securities on such terms. In the event that, within the respective prescribed periods, the Representatives notify the Company that you have so arranged for the purchase of such Securities, or the Company notifies the Representatives that it has so arranged for the purchase of such Securities, the Representatives or the Company shall have the right to postpone such Closing Date for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in the opinion of the Representatives may thereby be made necessary. The term "Underwriter" as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of such Securities which remains unpurchased does not exceed one eleventh of the aggregate principal amount of all the Securities, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities which such Underwriter agreed to purchase hereunder and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Securities which such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of Securities which remains unpurchased exceeds one eleventh of the aggregate principal amount of all the Securities, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Securities of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 7 hereof and the indemnity and contribution agreements in Section 11 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13. The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter, or any officer or director or controlling person of any Underwriter, or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;14. If this Agreement shall be terminated pursuant to Section 12 hereof, the Company shall not then be under any liability to any Underwriter except as provided in Sections 7 and 11 hereof; but, if for any other reason, the Securities are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters through the Representatives for all out of pocket expenses approved in writing by the Representatives, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Securities, but the Company shall then be under no further liability to any Underwriter except as provided in Sections 7 and 11 hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;15.

For the purposes of this Section 17,

"UK Underwriters" means Morgan Stanley & Co. International plc.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;18. Solely for the purposes of the requirements of 3.2.7R of the FCA Handbook Product Intervention and Product Governance Sourcebook (the "UK MiFIR Product Governance Rules") regarding the mutual responsibilities of manufacturers under the UK MiFIR Product Governance Rules:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Morgan Stanley & Co. International plc (the "UK Manufacturer") acknowledges that it understands the responsibilities conferred upon it under the UK MiFIR Product Governance Rules relating to each of the product approval process, the target market and the proposed distribution channels as applying to the Securities and the related information set out in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus or any such amendment or supplement, in connection with the Securities; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the Underwriters and the Company note the application of the UK MiFIR Product Governance Rules and acknowledge the target market and distribution channels identified as applying to the Securities by the UK Manufacturer and the related information set out in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus or any such amendment or supplement, in connection with the Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19. In recognition of the U.S. Special Resolutions Regimes, the Company and each of the Underwriters agree that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) For the purposes of this Section 19,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) "BHC Act Affiliate" has the meaning assigned to the term "affiliate" in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) "Covered Entity" means any of the following: (i) a "covered entity" as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (ii) a "covered bank" as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or (iii) a "covered FSI" as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) "Default Right" has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) "U.S. Special Resolution Regime" means each of (i) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (ii) Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;20. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company and, to the extent provided in Sections 11 and 13 hereof, the officers and directors of the Company and each person who controls the Company or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Securities from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;21. Time shall be of the essence of this Agreement. As used herein, the term "**business day**" shall mean any day when the Commission's office in Washington, D.C. is open for business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;22. The Company acknowledges and agrees that (i) the purchase and sale of the Securities pursuant to this Agreement is an arm's-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth in this Agreement and (iv) the Company has consulted its own legal and financial advisors to the extent it deemed appropriate. The Company agrees that it will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;23. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Underwriters, or any of them, with respect to the subject matter hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;24. **This Agreement shall be governed by and construed in accordance with the laws of the State of New York.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;25. The Company and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;26. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;27. Notwithstanding anything herein to the contrary, the Company is authorized to disclose to any persons the U.S. federal and state income tax treatment and tax structure of the potential transaction and all materials of any kind (including tax opinions and other tax analyses) provided to the Company relating to that treatment and structure, without the Underwriters' imposing any limitation of any kind. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, "tax structure" is limited to any facts that may be relevant to that treatment.

If the foregoing is in accordance with your understanding, please sign and return to us six counterparts hereof, and upon the acceptance hereof by you, on behalf of each of the Underwriters, this letter and such acceptance hereof shall constitute a binding agreement between each of the Underwriters and the Company.

THIS FORTY-FIRST SUPPLEMENTAL INDENTURE (this "Forty-First Supplemental Indenture") is made as of the 5th day of June, 2025, 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 Forty-First 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 Forty-First 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**

**1.726% SENIOR NOTES DUE 2030**

Section 1.01 <u>Establishment</u>. There is hereby established a new series of senior notes to be issued under the Indenture, to be designated as the Company's 1.726% Senior Notes due 2030 (the "Senior Notes").

There are to be authenticated and delivered Senior Notes, initially limited in aggregate principal amount to ¥35,000,000,000, 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 Forty-First 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; 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 <u>Definitions</u>. 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 or trust companies in the City of New York, Tokyo, or London, or the relevant place of payment, are authorized or required 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 June 5 and December 5 of each year, commencing on December 5, 2025, except that the final Interest Payment Date in 2030 shall be the Stated Maturity (short last coupon).

"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 May 15 or November 15 immediately preceding such Interest Payment Date.

"Stated Maturity" means October 18, 2030.

Section 1.03 <u>Payment of Principal and Interest</u>. 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 1.726% 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 June 5, 2025. Interest shall be paid semi-annually in arrears on each Interest Payment Date, commencing on December 5, 2025, 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. Except as described in Section 1.12 below, the principal of and interest on the Senior Notes shall be paid in Japanese yen. 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 <u>Denominations</u>. 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 <u>Global Securities</u>. 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 <u>Transfer</u>. 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 <u>Defeasance</u>. The provisions of Sections 10.4 and 10.5 of the Original Indenture will apply to the Senior Notes.

Section 1.08 <u>Redemption at the Option of the Company</u>. The Senior Notes will be redeemable, at the sole option of the Company, in whole or in part from time to time, on and after July 18, 2030 (three months prior to maturity), at a redemption price equal to 100% of the aggregate principal amount of the Senior Notes to be redeemed plus accrued and unpaid interest on the principal amount of the Senior Notes to be redeemed, if any, to, but excluding, the redemption date.

Notwithstanding Section 12.2 of the Original Indenture, notice of any redemption pursuant to this Section 1.08 of the Supplemental Indenture will be mailed at least 15 days but no more than 60 days before the redemption date to each holder of the Senior Notes to be redeemed at its registered address.

Section 1.09 <u>Selection of Senior Notes to be Redeemed</u>. 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 by the Trustee in accordance with the applicable procedures of Clearstream and Euroclear. Senior Notes, and portions of Senior Notes, may be selected in amounts of ¥100,000,000 and integral multiples of ¥10,000,000 in excess thereof.

Section 1.10 <u>Additional Amounts</u>. 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:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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,

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 1.11 <u>Tax Redemption</u>. Unless previously redeemed or repurchased and canceled, the Senior Notes will be repayable at par, including Additional Amounts, if any, on October 18, 2030, 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 or earlier date of redemption 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 or relevant redemption date 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 May 30, 2025, or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) any action shall have been taken by a taxing authority, or any action has been brought in a court of competent jurisdiction, in the United States or any political subdivision or taxing authority of or in the United States, including any of those actions specified in (a) above, whether or not such action was taken or brought with respect to the Company, or any change, clarification, amendment, application or interpretation of such laws, regulations or rulings shall be officially proposed, in any such case on or after May 30, 2025, which results in a substantial likelihood that the Company will be required to pay Additional Amounts on the next Interest Payment Date.

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 1.12 <u>Issuance in Yen</u>. If the yen is unavailable to the Company due to the imposition of exchange controls or other circumstances beyond its control, then all payments in respect of the Senior Notes will be made in U.S. dollars until the yen is again available to the Company. In such circumstances, the amount payable on any date in yen will be converted by the Company into U.S. dollars at the rate mandated by the Board of Governors of the Federal Reserve System as of the close of business on the second Business Day prior to the relevant payment date or, if the Board of Governors of the Federal Reserve System has not announced a rate of conversion, on the basis of the most recent U.S. dollar/yen exchange rate published in The Wall Street Journal on or prior to the second Business Day prior to the relevant payment date or, in the event The Wall Street Journal has not published such exchange rate, the rate will be determined in the Company's sole discretion on the basis of the most recently available market exchange rate for yen. Any payment in respect of the Senior Notes so made in U.S. dollars will not constitute an Event of Default under the Senior Notes or the Indenture.

Section 1.13 <u>Further Issues</u>. 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.

**ARTICLE II**

**MISCELLANEOUS PROVISIONS**

Section 2.01 <u>Recitals by the Company</u>. The recitals in this Forty-First 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 Forty-First 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 Forty-First Supplemental Indenture as fully and with like effect as if set forth herein in full.

Section 2.02 <u>Amendment to Sections 2.05 and 2.06 of the Original Indenture Relating to the Execution of Securities and the Certificate of Authentication</u>. 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 <u>Execution of Securities</u>. 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 <u>Certificate of Authentication</u>. 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 <u>Ratification and Incorporation of Original Indenture</u>. As supplemented hereby, the Original Indenture is in all respects ratified and confirmed, and the Original Indenture and this Forty-First Supplemental Indenture shall be read, taken and construed as one and the same instrument.

Section 2.04 <u>Executed in Counterparts</u>. This Forty-First 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 Forty-First 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 <u>New York Law to Govern</u>. This Forty-First 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.

Aflac Incorporated, a Georgia corporation (the "Company," which term includes any successor corporation under the Indenture referred to on the reverse hereof), for value received, hereby promises to pay to The Bank of New York Depository (Nominees) Limited, the registered holder hereof, as nominee of The Bank of New York Mellon, London Branch, as common depositary for Euroclear/Clearstream, or registered assigns, the principal sum of THIRTY-FIVE BILLION JAPANESE YEN (¥35,000,000,000) on the Stated Maturity shown above, and to pay interest thereon, and on any overdue installment of interest thereon to the extent permitted by law, 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 the Original Issue Date shown above, semi-annually in arrears on each Interest Payment Date as specified above, commencing on December 5, 2025, and on the Stated Maturity at the rate per year shown above until the principal hereof or such overdue installment is paid or made available for payment. The interest so payable, and punctually paid or duly provided for, on an Interest Payment Date (other than an Interest Payment Date that is the Stated Maturity) will, as provided in the Indenture, be paid to the Person in whose name this Note (as defined on the reverse hereof) is registered at the close of business on the Regular Record Date as specified above next preceding such Interest Payment Date, provided that any interest payable at the Stated Maturity or on a redemption date will be paid to the Person to whom principal is payable. Except as otherwise provided in the Indenture, 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 this Note (as defined on the reverse hereof) will include interest accrued to but excluding the respective Interest Payment Dates.

For the purposes of this Note, "Business Day" means each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day in which banking institutions or trust companies in the City of New York, Tokyo, or London, or the relevant place of payment, are authorized or required by law, regulation or executive order to close.

The Senior Notes will rank senior to any subordinated indebtedness of the Company.

REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS NOTE SET FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.

(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 Forty-First Supplemental Indenture dated as of June 5, 2025 (the "Forty-First 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 1.726% Senior Notes due 2030 (the "Senior Notes"), initially limited in aggregate principal amount to ¥35,000,000,000; 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 Forty-First 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.

The Senior Notes will be redeemable, at the sole option of the Company, in whole or in part from time to time, on and after July 18, 2030 (three months prior to maturity), at a redemption price equal to 100% of the aggregate principal amount of the Senior Notes to be redeemed plus accrued and unpaid interest on the principal amount of the Senior Notes to be redeemed, if any, to, but excluding, the redemption date.

Notice of any redemption at the option of the Company will be mailed at least 15 days but no more than 60 days before the redemption date to each holder of the Senior Notes to be redeemed at its registered address.

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:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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,

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

Unless previously redeemed or repurchased and canceled, the Senior Notes will be repayable at par, including Additional Amounts, if any, on October 18, 2030, 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 or earlier date of redemption 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 or relevant redemption date 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 May 30, 2025 or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) any action shall have been taken by a taxing authority, or any action has been brought in a court of competent jurisdiction, in the United States or any political subdivision or taxing authority of or in the United States, including any of those actions specified in (a) above, whether or not such action was taken or brought with respect to the Company, or any change, clarification, amendment, application or interpretation of such laws, regulations or rulings shall be officially proposed, in any such case on or after May 30, 2025, which results in a substantial likelihood that the Company will be required to pay Additional Amounts on the next Interest Payment Date. 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

If the yen is unavailable to the Company due to the imposition of exchange controls or other circumstances beyond its control, then all payments in respect of the Senior Notes will be made in U.S. dollars until the yen is again available to the Company. In such circumstances, the amount payable on any date in yen will be converted by the Company into U.S. dollars at the rate mandated by the Board of Governors of the Federal Reserve System as of the close of business on the second Business Day prior to the relevant payment date or, if the Board of Governors of the Federal Reserve System has not announced a rate of conversion, on the basis of the most recent U.S. dollar/yen exchange rate published in The Wall Street Journal on or prior to the second Business Day prior to the relevant payment date or, in the event The Wall Street Journal has not published such exchange rate, the rate will be determined in the Company's sole discretion on the basis of the most recently available market exchange rate for yen.

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.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable in the Security register, upon surrender of this Note for registration of transfer at the office or agency of the Company for such purpose, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company or the Security registrar and duly executed by, the holder hereof or his attorney duly authorized in writing, and thereupon one or more new Senior Notes, of authorized denominations and of like tenor and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 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.

Prior to due presentment of this Note for registration of transfer, the Company, the Trustee, any Person authorized by the Company to pay the principal of or any premium or interest on any Senior Note on behalf of the Company (a "Paying Agent") and the Security registrar may deem and treat the Person in whose name this Note is registered as the absolute owner hereof for all purposes, whether or not this Note be overdue and notwithstanding any notice of ownership or writing thereon made by anyone other than the Security registrar, and neither the Company nor the Trustee nor any Paying Agent nor the Security registrar shall be affected by notice to the contrary.

The Senior Notes are issuable only in registered form without coupons in denominations of ¥100,000,000 and integral multiples of ¥10,000,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes of a different authorized denomination, as requested by the holder surrendering the same upon surrender of the Senior Note or Senior Notes to be exchanged at the office or agency of the Company.

No recourse shall be had for payment of the principal of or interest on this Note, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture, against any incorporator, as such or against any past, present or future shareholder, officer or director, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule, law statute or constitutional provision, or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released, by the acceptance hereof and as part of the consideration for the issuance hereof.

Unless the certificate of authentication hereon has been executed by the Trustee by manual, facsimile or electronic signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

This Note shall be governed by, and construed in accordance with, the internal laws of the state of New York.

THIS FORTY-SECOND SUPPLEMENTAL INDENTURE (this "Forty-Second Supplemental Indenture") is made as of the 5th day of June, 2025, 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 Forty-Second 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 Forty-Second 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**

**2.003% SENIOR NOTES DUE 2032**

Section 1.01 <u>Establishment</u>. There is hereby established a new series of senior notes to be issued under the Indenture, to be designated as the Company's 2.003% Senior Notes due 2032 (the "Senior Notes").

There are to be authenticated and delivered Senior Notes, initially limited in aggregate principal amount to ¥23,400,000,000, 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 Forty-Second 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; 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 <u>Definitions</u>. 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 or trust companies in the City of New York, Tokyo, or London, or the relevant place of payment, are authorized or required 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 June 5 and December 5 of each year, commencing on December 5, 2025, except that the final Interest Payment Date in 2032 shall be the Stated Maturity (long last coupon).

"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 May 15 or November 15 immediately preceding such Interest Payment Date.

"Stated Maturity" means December 14, 2032.

Section 1.03 <u>Payment of Principal and Interest</u>. 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 2.003% 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 June 5, 2025. Interest shall be paid semi-annually in arrears on each Interest Payment Date, commencing on December 5, 2025, 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. Except as described in Section 1.12 below, the principal of and interest on the Senior Notes shall be paid in Japanese yen. 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 <u>Denominations</u>. 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 <u>Global Securities</u>. 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 <u>Transfer</u>. 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 <u>Defeasance</u>. The provisions of Sections 10.4 and 10.5 of the Original Indenture will apply to the Senior Notes.

Section 1.08 <u>Redemption at the Option of the Company</u>. The Senior Notes will be redeemable, at the sole option of the Company, in whole or in part from time to time, on and after September 14, 2032 (three months prior to maturity), at a redemption price equal to 100% of the aggregate principal amount of the Senior Notes to be redeemed plus accrued and unpaid interest on the principal amount of the Senior Notes to be redeemed, if any, to, but excluding, the redemption date.

Notwithstanding Section 12.2 of the Original Indenture, notice of any redemption pursuant to this Section 1.08 of the Supplemental Indenture will be mailed at least 15 days but no more than 60 days before the redemption date to each holder of the Senior Notes to be redeemed at its registered address.

Section 1.09 <u>Selection of Senior Notes to be Redeemed</u>. 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 by the Trustee in accordance with the applicable procedures of Clearstream and Euroclear. Senior Notes, and portions of Senior Notes, may be selected in amounts of ¥100,000,000 and integral multiples of ¥10,000,000 in excess thereof.

Section 1.10 <u>Additional Amounts</u>. 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:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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,

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 1.11 <u>Tax Redemption</u>. Unless previously redeemed or repurchased and canceled, the Senior Notes will be repayable at par, including Additional Amounts, if any, on December 14, 2032, 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 or earlier date of redemption 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 or relevant redemption date 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 May 30, 2025, or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) any action shall have been taken by a taxing authority, or any action has been brought in a court of competent jurisdiction, in the United States or any political subdivision or taxing authority of or in the United States, including any of those actions specified in (a) above, whether or not such action was taken or brought with respect to the Company, or any change, clarification, amendment, application or interpretation of such laws, regulations or rulings shall be officially proposed, in any such case on or after May 30, 2025, which results in a substantial likelihood that the Company will be required to pay Additional Amounts on the next Interest Payment Date.

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 1.12 <u>Issuance in Yen</u>. If the yen is unavailable to the Company due to the imposition of exchange controls or other circumstances beyond its control, then all payments in respect of the Senior Notes will be made in U.S. dollars until the yen is again available to the Company. In such circumstances, the amount payable on any date in yen will be converted by the Company into U.S. dollars at the rate mandated by the Board of Governors of the Federal Reserve System as of the close of business on the second Business Day prior to the relevant payment date or, if the Board of Governors of the Federal Reserve System has not announced a rate of conversion, on the basis of the most recent U.S. dollar/yen exchange rate published in The Wall Street Journal on or prior to the second Business Day prior to the relevant payment date or, in the event The Wall Street Journal has not published such exchange rate, the rate will be determined in the Company's sole discretion on the basis of the most recently available market exchange rate for yen. Any payment in respect of the Senior Notes so made in U.S. dollars will not constitute an Event of Default under the Senior Notes or the Indenture.

Section 1.13 <u>Further Issues</u>. 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.

**ARTICLE II**

**MISCELLANEOUS PROVISIONS**

Section 2.01 <u>Recitals by the Company</u>. The recitals in this Forty-Second 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 Forty-Second 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 Forty-Second Supplemental Indenture as fully and with like effect as if set forth herein in full.

Section 2.02 <u>Amendment to Sections 2.05 and 2.06 of the Original Indenture Relating to the Execution of Securities and the Certificate of Authentication</u>. 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 <u>Execution of Securities</u>. 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 <u>Certificate of Authentication</u>. 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 <u>Ratification and Incorporation of Original Indenture</u>. As supplemented hereby, the Original Indenture is in all respects ratified and confirmed, and the Original Indenture and this Forty-Second Supplemental Indenture shall be read, taken and construed as one and the same instrument.

Section 2.04 <u>Executed in Counterparts</u>. This Forty-Second 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 Forty-Second 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 <u>New York Law to Govern</u>. This Forty-Second 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.

Aflac Incorporated, a Georgia corporation (the "Company," which term includes any successor corporation under the Indenture referred to on the reverse hereof), for value received, hereby promises to pay to The Bank of New York Depository (Nominees) Limited, the registered holder hereof, as nominee of The Bank of New York Mellon, London Branch, as common depositary for Euroclear/Clearstream, or registered assigns, the principal sum of TWENTY-THREE BILLION FOUR HUNDRED MILLION JAPANESE YEN (¥23,400,000,000) on the Stated Maturity shown above, and to pay interest thereon, and on any overdue installment of interest thereon to the extent permitted by law, 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 the Original Issue Date shown above, semi-annually in arrears on each Interest Payment Date as specified above, commencing on December 5, 2025, and on the Stated Maturity at the rate per year shown above until the principal hereof or such overdue installment is paid or made available for payment. The interest so payable, and punctually paid or duly provided for, on an Interest Payment Date (other than an Interest Payment Date that is the Stated Maturity) will, as provided in the Indenture, be paid to the Person in whose name this Note (as defined on the reverse hereof) is registered at the close of business on the Regular Record Date as specified above next preceding such Interest Payment Date, provided that any interest payable at the Stated Maturity or on a redemption date will be paid to the Person to whom principal is payable. Except as otherwise provided in the Indenture, 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.

The Senior Notes will rank senior to any subordinated indebtedness of the Company.

REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS NOTE SET FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.

(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 Forty-Second Supplemental Indenture dated as of June 5, 2025 (the "Forty-Second 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 2.003% Senior Notes due 2032 (the "Senior Notes"), initially limited in aggregate principal amount to ¥23,400,000,000; 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 Forty-Second 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.

The Senior Notes will be redeemable, at the sole option of the Company, in whole or in part from time to time, on and after September 14, 2032 (three months prior to maturity), at a redemption price equal to 100% of the aggregate principal amount of the Senior Notes to be redeemed plus accrued and unpaid interest on the principal amount of the Senior Notes to be redeemed, if any, to, but excluding, the redemption date.

Notice of any redemption at the option of the Company will be mailed at least 15 days but no more than 60 days before the redemption date to each holder of the Senior Notes to be redeemed at its registered address.

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:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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,

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

Unless previously redeemed or repurchased and canceled, the Senior Notes will be repayable at par, including Additional Amounts, if any, on December 14, 2032, 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 or earlier date of redemption 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 or relevant redemption date 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 May 30, 2025 or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) any action shall have been taken by a taxing authority, or any action has been brought in a court of competent jurisdiction, in the United States or any political subdivision or taxing authority of or in the United States, including any of those actions specified in (a) above, whether or not such action was taken or brought with respect to the Company, or any change, clarification, amendment, application or interpretation of such laws, regulations or rulings shall be officially proposed, in any such case on or after May 30, 2025, which results in a substantial likelihood that the Company will be required to pay Additional Amounts on the next Interest Payment Date. 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

If the yen is unavailable to the Company due to the imposition of exchange controls or other circumstances beyond its control, then all payments in respect of the Senior Notes will be made in U.S. dollars until the yen is again available to the Company. In such circumstances, the amount payable on any date in yen will be converted by the Company into U.S. dollars at the rate mandated by the Board of Governors of the Federal Reserve System as of the close of business on the second Business Day prior to the relevant payment date or, if the Board of Governors of the Federal Reserve System has not announced a rate of conversion, on the basis of the most recent U.S. dollar/yen exchange rate published in The Wall Street Journal on or prior to the second Business Day prior to the relevant payment date or, in the event The Wall Street Journal has not published such exchange rate, the rate will be determined in the Company's sole discretion on the basis of the most recently available market exchange rate for yen.

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.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable in the Security register, upon surrender of this Note for registration of transfer at the office or agency of the Company for such purpose, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company or the Security registrar and duly executed by, the holder hereof or his attorney duly authorized in writing, and thereupon one or more new Senior Notes, of authorized denominations and of like tenor and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 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.

Prior to due presentment of this Note for registration of transfer, the Company, the Trustee, any Person authorized by the Company to pay the principal of or any premium or interest on any Senior Note on behalf of the Company (a "Paying Agent") and the Security registrar may deem and treat the Person in whose name this Note is registered as the absolute owner hereof for all purposes, whether or not this Note be overdue and notwithstanding any notice of ownership or writing thereon made by anyone other than the Security registrar, and neither the Company nor the Trustee nor any Paying Agent nor the Security registrar shall be affected by notice to the contrary.

The Senior Notes are issuable only in registered form without coupons in denominations of ¥100,000,000 and integral multiples of ¥10,000,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes of a different authorized denomination, as requested by the holder surrendering the same upon surrender of the Senior Note or Senior Notes to be exchanged at the office or agency of the Company.

No recourse shall be had for payment of the principal of or interest on this Note, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture, against any incorporator, as such or against any past, present or future shareholder, officer or director, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule, law statute or constitutional provision, or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released, by the acceptance hereof and as part of the consideration for the issuance hereof.

Unless the certificate of authentication hereon has been executed by the Trustee by manual, facsimile or electronic signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

This Note shall be governed by, and construed in accordance with, the internal laws of the state of New York.

THIS FORTY-THIRD SUPPLEMENTAL INDENTURE (this "Forty-Third Supplemental Indenture") is made as of the 5th day of June, 2025, 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 Forty-Third 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 Forty-Third 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**

**2.369% SENIOR NOTES DUE 2035**

Section 1.01 <u>Establishment</u>. There is hereby established a new series of senior notes to be issued under the Indenture, to be designated as the Company's 2.369% Senior Notes due 2035 (the "Senior Notes").

There are to be authenticated and delivered Senior Notes, initially limited in aggregate principal amount to ¥9,500,000,000, 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 Forty-Third 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; 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 <u>Definitions</u>. 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 or trust companies in the City of New York, Tokyo, or London, or the relevant place of payment, are authorized or required 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 June 5 and December 5 of each year, commencing on December 5, 2025.

"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 May 15 or November 15 immediately preceding such Interest Payment Date.

"Stated Maturity" means June 5, 2035.

Section 1.03 <u>Payment of Principal and Interest</u>. 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 2.369% 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 June 5, 2025. Interest shall be paid semi-annually in arrears on each Interest Payment Date, commencing on December 5, 2025, 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. Except as described in Section 1.12 below, the principal of and interest on the Senior Notes shall be paid in Japanese yen. 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 <u>Denominations</u>. 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 <u>Global Securities</u>. 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 <u>Transfer</u>. 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 <u>Defeasance</u>. The provisions of Sections 10.4 and 10.5 of the Original Indenture will apply to the Senior Notes.

Section 1.08 <u>Redemption at the Option of the Company</u>. The Senior Notes will be redeemable, at the sole option of the Company, in whole or in part from time to time, on and after December 5, 2034 (six months prior to maturity), at a redemption price equal to 100% of the aggregate principal amount of the Senior Notes to be redeemed plus accrued and unpaid interest on the principal amount of the Senior Notes to be redeemed, if any, to, but excluding, the redemption date.

Notwithstanding Section 12.2 of the Original Indenture, notice of any redemption pursuant to this Section 1.08 of the Supplemental Indenture will be mailed at least 15 days but no more than 60 days before the redemption date to each holder of the Senior Notes to be redeemed at its registered address.

Section 1.09 <u>Selection of Senior Notes to be Redeemed</u>. 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 by the Trustee in accordance with the applicable procedures of Clearstream and Euroclear. Senior Notes, and portions of Senior Notes, may be selected in amounts of ¥100,000,000 and integral multiples of ¥10,000,000 in excess thereof.

Section 1.10 <u>Additional Amounts</u>. 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:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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,

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 1.11 <u>Tax Redemption</u>. Unless previously redeemed or repurchased and canceled, the Senior Notes will be repayable at par, including Additional Amounts, if any, on June 5, 2035, 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 or earlier date of redemption 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 or relevant redemption date 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 May 30, 2025, or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) any action shall have been taken by a taxing authority, or any action has been brought in a court of competent jurisdiction, in the United States or any political subdivision or taxing authority of or in the United States, including any of those actions specified in (a) above, whether or not such action was taken or brought with respect to the Company, or any change, clarification, amendment, application or interpretation of such laws, regulations or rulings shall be officially proposed, in any such case on or after May 30, 2025, which results in a substantial likelihood that the Company will be required to pay Additional Amounts on the next Interest Payment Date.

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 1.12 <u>Issuance in Yen</u>. If the yen is unavailable to the Company due to the imposition of exchange controls or other circumstances beyond its control, then all payments in respect of the Senior Notes will be made in U.S. dollars until the yen is again available to the Company. In such circumstances, the amount payable on any date in yen will be converted by the Company into U.S. dollars at the rate mandated by the Board of Governors of the Federal Reserve System as of the close of business on the second Business Day prior to the relevant payment date or, if the Board of Governors of the Federal Reserve System has not announced a rate of conversion, on the basis of the most recent U.S. dollar/yen exchange rate published in The Wall Street Journal on or prior to the second Business Day prior to the relevant payment date or, in the event The Wall Street Journal has not published such exchange rate, the rate will be determined in the Company's sole discretion on the basis of the most recently available market exchange rate for yen. Any payment in respect of the Senior Notes so made in U.S. dollars will not constitute an Event of Default under the Senior Notes or the Indenture.

Section 1.13 <u>Further Issues</u>. 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.

**ARTICLE II**

**MISCELLANEOUS PROVISIONS**

Section 2.01 <u>Recitals by the Company</u>. The recitals in this Forty-Third 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 Forty-Third 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 Forty-Third Supplemental Indenture as fully and with like effect as if set forth herein in full.

Section 2.02 <u>Amendment to Sections 2.05 and 2.06 of the Original Indenture Relating to the Execution of Securities and the Certificate of Authentication</u>. 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 <u>Execution of Securities</u>. 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 <u>Certificate of Authentication</u>. 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 <u>Ratification and Incorporation of Original Indenture</u>. As supplemented hereby, the Original Indenture is in all respects ratified and confirmed, and the Original Indenture and this Forty-Third Supplemental Indenture shall be read, taken and construed as one and the same instrument.

Section 2.04 <u>Executed in Counterparts</u>. This Forty-Third 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 Forty-Third 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 <u>New York Law to Govern</u>. This Forty-Third 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.

Aflac Incorporated, a Georgia corporation (the "Company," which term includes any successor corporation under the Indenture referred to on the reverse hereof), for value received, hereby promises to pay to The Bank of New York Depository (Nominees) Limited, the registered holder hereof, as nominee of The Bank of New York Mellon, London Branch, as common depositary for Euroclear/Clearstream, or registered assigns, the principal sum of NINE BILLION FIVE HUNDRED MILLION JAPANESE YEN (¥9,500,000,000) on the Stated Maturity shown above, and to pay interest thereon, and on any overdue installment of interest thereon to the extent permitted by law, 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 the Original Issue Date shown above, semi-annually in arrears on each Interest Payment Date as specified above, commencing on December 5, 2025, and on the Stated Maturity at the rate per year shown above until the principal hereof or such overdue installment is paid or made available for payment. The interest so payable, and punctually paid or duly provided for, on an Interest Payment Date (other than an Interest Payment Date that is the Stated Maturity) will, as provided in the Indenture, be paid to the Person in whose name this Note (as defined on the reverse hereof) is registered at the close of business on the Regular Record Date as specified above next preceding such Interest Payment Date, provided that any interest payable at the Stated Maturity or on a redemption date will be paid to the Person to whom principal is payable.

(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 Forty-Third Supplemental Indenture dated as of June 5, 2025 (the "Forty-Third 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 2.369% Senior Notes due 2035 (the "Senior Notes"), initially limited in aggregate principal amount to ¥9,500,000,000; 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 Forty-Third 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.

The Senior Notes will be redeemable, at the sole option of the Company, in whole or in part from time to time, on and after December 5, 2034 (six months prior to maturity), at a redemption price equal to 100% of the aggregate principal amount of the Senior Notes to be redeemed plus accrued and unpaid interest on the principal amount of the Senior Notes to be redeemed, if any, to, but excluding, the redemption date.

Notice of any redemption at the option of the Company will be mailed at least 15 days but no more than 60 days before the redemption date to each holder of the Senior Notes to be redeemed at its registered address.

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:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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,

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

Unless previously redeemed or repurchased and canceled, the Senior Notes will be repayable at par, including Additional Amounts, if any, on June 5, 2035, 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 or earlier date of redemption 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 or relevant redemption date 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 May 30, 2025 or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) any action shall have been taken by a taxing authority, or any action has been brought in a court of competent jurisdiction, in the United States or any political subdivision or taxing authority of or in the United States, including any of those actions specified in (a) above, whether or not such action was taken or brought with respect to the Company, or any change, clarification, amendment, application or interpretation of such laws, regulations or rulings shall be officially proposed, in any such case on or after May 30, 2025, which results in a substantial likelihood that the Company will be required to pay Additional Amounts on the next Interest Payment Date. 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

If the yen is unavailable to the Company due to the imposition of exchange controls or other circumstances beyond its control, then all payments in respect of the Senior Notes will be made in U.S. dollars until the yen is again available to the Company. In such circumstances, the amount payable on any date in yen will be converted by the Company into U.S. dollars at the rate mandated by the Board of Governors of the Federal Reserve System as of the close of business on the second Business Day prior to the relevant payment date or, if the Board of Governors of the Federal Reserve System has not announced a rate of conversion, on the basis of the most recent U.S. dollar/yen exchange rate published in The Wall Street Journal on or prior to the second Business Day prior to the relevant payment date or, in the event The Wall Street Journal has not published such exchange rate, the rate will be determined in the Company's sole discretion on the basis of the most recently available market exchange rate for yen.

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.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable in the Security register, upon surrender of this Note for registration of transfer at the office or agency of the Company for such purpose, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company or the Security registrar and duly executed by, the holder hereof or his attorney duly authorized in writing, and thereupon one or more new Senior Notes, of authorized denominations and of like tenor and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 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.

Prior to due presentment of this Note for registration of transfer, the Company, the Trustee, any Person authorized by the Company to pay the principal of or any premium or interest on any Senior Note on behalf of the Company (a "Paying Agent") and the Security registrar may deem and treat the Person in whose name this Note is registered as the absolute owner hereof for all purposes, whether or not this Note be overdue and notwithstanding any notice of ownership or writing thereon made by anyone other than the Security registrar, and neither the Company nor the Trustee nor any Paying Agent nor the Security registrar shall be affected by notice to the contrary.

The Senior Notes are issuable only in registered form without coupons in denominations of ¥100,000,000 and integral multiples of ¥10,000,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes of a different authorized denomination, as requested by the holder surrendering the same upon surrender of the Senior Note or Senior Notes to be exchanged at the office or agency of the Company.

No recourse shall be had for payment of the principal of or interest on this Note, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture, against any incorporator, as such or against any past, present or future shareholder, officer or director, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule, law statute or constitutional provision, or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released, by the acceptance hereof and as part of the consideration for the issuance hereof.

Unless the certificate of authentication hereon has been executed by the Trustee by manual, facsimile or electronic signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

This Note shall be governed by, and construed in accordance with, the internal laws of the state of New York.

THIS FORTY-FOURTH SUPPLEMENTAL INDENTURE (this "Forty-Fourth Supplemental Indenture") is made as of the 5th day of June, 2025, 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 Forty-Fourth 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 Forty-Fourth 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**

**2.779% SENIOR NOTES DUE 2040**

Section 1.01 <u>Establishment</u>. There is hereby established a new series of senior notes to be issued under the Indenture, to be designated as the Company's 2.779% Senior Notes due 2040 (the "Senior Notes").

There are to be authenticated and delivered Senior Notes, initially limited in aggregate principal amount to ¥7,000,000,000, 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 Forty-Fourth 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; 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 <u>Definitions</u>. 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 or trust companies in the City of New York, Tokyo, or London, or the relevant place of payment, are authorized or required 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 June 5 and December 5 of each year, commencing on December 5, 2025.

"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 May 15 or November 15 immediately preceding such Interest Payment Date.

"Stated Maturity" means June 5, 2040.

Section 1.03 <u>Payment of Principal and Interest</u>. 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 2.779% 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 June 5, 2025. Interest shall be paid semi-annually in arrears on each Interest Payment Date, commencing on December 5, 2025, 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. Except as described in Section 1.12 below, the principal of and interest on the Senior Notes shall be paid in Japanese yen. 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 <u>Denominations</u>. 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 <u>Global Securities</u>. 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 <u>Transfer</u>. 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 <u>Defeasance</u>. The provisions of Sections 10.4 and 10.5 of the Original Indenture will apply to the Senior Notes.

Section 1.08 <u>Redemption at the Option of the Company</u>. The Senior Notes will be redeemable, at the sole option of the Company, in whole or in part from time to time, on and after December 5, 2039 (six months prior to maturity), at a redemption price equal to 100% of the aggregate principal amount of the Senior Notes to be redeemed plus accrued and unpaid interest on the principal amount of the Senior Notes to be redeemed, if any, to, but excluding, the redemption date.

Notwithstanding Section 12.2 of the Original Indenture, notice of any redemption pursuant to this Section 1.08 of the Supplemental Indenture will be mailed at least 15 days but no more than 60 days before the redemption date to each holder of the Senior Notes to be redeemed at its registered address.

Section 1.09 <u>Selection of Senior Notes to be Redeemed</u>. 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 by the Trustee in accordance with the applicable procedures of Clearstream and Euroclear. Senior Notes, and portions of Senior Notes, may be selected in amounts of ¥100,000,000 and integral multiples of ¥10,000,000 in excess thereof.

Section 1.10 <u>Additional Amounts</u>. 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:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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,

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 1.11 <u>Tax Redemption</u>. Unless previously redeemed or repurchased and canceled, the Senior Notes will be repayable at par, including Additional Amounts, if any, on June 5, 2040, 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 or earlier date of redemption 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 or relevant redemption date 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 May 30, 2025, or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) any action shall have been taken by a taxing authority, or any action has been brought in a court of competent jurisdiction, in the United States or any political subdivision or taxing authority of or in the United States, including any of those actions specified in (a) above, whether or not such action was taken or brought with respect to the Company, or any change, clarification, amendment, application or interpretation of such laws, regulations or rulings shall be officially proposed, in any such case on or after May 30, 2025, which results in a substantial likelihood that the Company will be required to pay Additional Amounts on the next Interest Payment Date.

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 1.12 <u>Issuance in Yen</u>. If the yen is unavailable to the Company due to the imposition of exchange controls or other circumstances beyond its control, then all payments in respect of the Senior Notes will be made in U.S. dollars until the yen is again available to the Company. In such circumstances, the amount payable on any date in yen will be converted by the Company into U.S. dollars at the rate mandated by the Board of Governors of the Federal Reserve System as of the close of business on the second Business Day prior to the relevant payment date or, if the Board of Governors of the Federal Reserve System has not announced a rate of conversion, on the basis of the most recent U.S. dollar/yen exchange rate published in The Wall Street Journal on or prior to the second Business Day prior to the relevant payment date or, in the event The Wall Street Journal has not published such exchange rate, the rate will be determined in the Company's sole discretion on the basis of the most recently available market exchange rate for yen. Any payment in respect of the Senior Notes so made in U.S. dollars will not constitute an Event of Default under the Senior Notes or the Indenture.

Section 1.13 <u>Further Issues</u>. 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.

**ARTICLE II**

**MISCELLANEOUS PROVISIONS**

Section 2.01 <u>Recitals by the Company</u>. The recitals in this Forty-Fourth 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 Forty-Fourth 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 Forty-Fourth Supplemental Indenture as fully and with like effect as if set forth herein in full.

Section 2.02 <u>Amendment to Sections 2.05 and 2.06 of the Original Indenture Relating to the Execution of Securities and the Certificate of Authentication</u>. 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 <u>Execution of Securities</u>. 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 <u>Certificate of Authentication</u>. 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 <u>Ratification and Incorporation of Original Indenture</u>. As supplemented hereby, the Original Indenture is in all respects ratified and confirmed, and the Original Indenture and this Forty-Fourth Supplemental Indenture shall be read, taken and construed as one and the same instrument.

Section 2.04 <u>Executed in Counterparts</u>. This Forty-Fourth 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 Forty-Fourth 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 <u>New York Law to Govern</u>. This Forty-Fourth 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.

Aflac Incorporated, a Georgia corporation (the "Company," which term includes any successor corporation under the Indenture referred to on the reverse hereof), for value received, hereby promises to pay to The Bank of New York Depository (Nominees) Limited, the registered holder hereof, as nominee of The Bank of New York Mellon, London Branch, as common depositary for Euroclear/Clearstream, or registered assigns, the principal sum of SEVEN BILLION JAPANESE YEN (¥7,000,000,000) on the Stated Maturity shown above, and to pay interest thereon, and on any overdue installment of interest thereon to the extent permitted by law, 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 the Original Issue Date shown above, semi-annually in arrears on each Interest Payment Date as specified above, commencing on December 5, 2025, and on the Stated Maturity at the rate per year shown above until the principal hereof or such overdue installment is paid or made available for payment. The interest so payable, and punctually paid or duly provided for, on an Interest Payment Date (other than an Interest Payment Date that is the Stated Maturity) will, as provided in the Indenture, be paid to the Person in whose name this Note (as defined on the reverse hereof) is registered at the close of business on the Regular Record Date as specified above next preceding such Interest Payment Date, provided that any interest payable at the Stated Maturity or on a redemption date will be paid to the Person to whom principal is payable. Except as otherwise provided in the Indenture, 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.

For the purposes of this Note, "Business Day" means each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day in which banking institutions or trust companies in the City of New York, Tokyo, or London, or the relevant place of payment, are authorized or required by law, regulation or executive order to close.

(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 Forty-Fourth Supplemental Indenture dated as of June 5, 2025 (the "Forty-Fourth 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 2.779% Senior Notes due 2040 (the "Senior Notes"), initially limited in aggregate principal amount to ¥7,000,000,000; 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 Forty-Fourth 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.

The Senior Notes will be redeemable, at the sole option of the Company, in whole or in part from time to time, on and after December 5, 2039 (six months prior to maturity), at a redemption price equal to 100% of the aggregate principal amount of the Senior Notes to be redeemed plus accrued and unpaid interest on the principal amount of the Senior Notes to be redeemed, if any, to, but excluding, the redemption date.

Notice of any redemption at the option of the Company will be mailed at least 15 days but no more than 60 days before the redemption date to each holder of the Senior Notes to be redeemed at its registered address.

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:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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,

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

Unless previously redeemed or repurchased and canceled, the Senior Notes will be repayable at par, including Additional Amounts, if any, on June 5, 2040, 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 or earlier date of redemption 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 or relevant redemption date 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 May 30, 2025 or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) any action shall have been taken by a taxing authority, or any action has been brought in a court of competent jurisdiction, in the United States or any political subdivision or taxing authority of or in the United States, including any of those actions specified in (a) above, whether or not such action was taken or brought with respect to the Company, or any change, clarification, amendment, application or interpretation of such laws, regulations or rulings shall be officially proposed, in any such case on or after May 30, 2025, which results in a substantial likelihood that the Company will be required to pay Additional Amounts on the next Interest Payment Date. 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

If the yen is unavailable to the Company due to the imposition of exchange controls or other circumstances beyond its control, then all payments in respect of the Senior Notes will be made in U.S. dollars until the yen is again available to the Company. In such circumstances, the amount payable on any date in yen will be converted by the Company into U.S. dollars at the rate mandated by the Board of Governors of the Federal Reserve System as of the close of business on the second Business Day prior to the relevant payment date or, if the Board of Governors of the Federal Reserve System has not announced a rate of conversion, on the basis of the most recent U.S. dollar/yen exchange rate published in The Wall Street Journal on or prior to the second Business Day prior to the relevant payment date or, in the event The Wall Street Journal has not published such exchange rate, the rate will be determined in the Company's sole discretion on the basis of the most recently available market exchange rate for yen.

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.

The Notes were offered for sale pursuant to the base prospectus accompanying the Registration Statement, as supplemented by a prospectus supplement relating to the Notes dated May 30, 2025 (the base prospectus, the prospectus supplement and any amendments thereto, collectively, the "Prospectus"). The Notes are to be issued under an indenture, dated as of May 21, 2009 (the "Base Indenture"), between the Company, as issuer, and The Bank of New York Mellon Trust Company, N.A., as trustee (the "Trustee"), as supplemented by (i) a Forty-First Supplemental Indenture, dated as of June 5, 2025 (the "Forty-First Supplemental Indenture"), between the Company and the Trustee, in the case of the 2030 Notes, (ii) a Forty-Second Supplemental Indenture, dated as of June 5, 2025 (the "Forty-Second Supplemental Indenture"), between the Company and the Trustee, in the case of the 2032 Notes, (iii) a Forty-Third Supplemental Indenture, dated as of June 5, 2025 (the "Forty-Third Supplemental Indenture"), and (iv) a Forty-Fourth Supplemental Indenture, dated as of June 5, 2025 (the "Forty-Fourth Supplemental Indenture"), between the Company and the Trustee, in the case of the 2040 Notes.

This opinion is being furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

In connection with rendering the opinions set forth below, I, or attorneys under my supervision, have examined the Registration Statement, the Prospectus contained therein, the Indenture, the Articles of Incorporation of the Company, as certified by the Secretary of State of the State of Georgia, the Bylaws of the Company, as certified by J. Matthew Loudermilk, Corporate Secretary of the Company, resolutions of the Board of Directors of the Company adopted on August 13, 2024 and February 11, 2025, as certified by J. Matthew Loudermilk, Corporate Secretary of the Company. I have also examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and such agreements, certificates and receipts of public officials, certificates of officers or other representatives of the Company and others, and such other documents as I have deemed necessary or appropriate as a basis for the opinions set forth below. In my examination, I have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to me as originals, the conformity to original documents of all documents submitted to me as facsimile, electronic, certified or photostatic copies, and the authenticity of the originals of such copies. I have also made such other investigation as I have deemed appropriate.

Based upon the foregoing, I am of the opinion that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Georgia, with the corporate power and authority to execute and deliver the Indenture and the Notes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. The Company has taken all necessary corporate action to authorize the execution and delivery of the Indenture and the Notes and to perform its obligations thereunder.

The opinions set forth above are subject to the following qualifications, exclusions and limitations:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) I express no opinion with respect to the execution, delivery, validity, binding effect or enforceability of any of the Indenture and the Notes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) My opinions are limited to the laws of the State of Georgia, and I do not express any opinion concerning any other law. Without limiting the generality of the foregoing, I express no opinion with respect to any securities laws or regulations.

The foregoing opinions are being furnished only for the purpose referred to in the first paragraph of this opinion letter. I hereby consent to the filing of this opinion as Exhibit 5.1 to a Current Report on Form 8-K being filed on the date hereof, and incorporated by reference into the Registration Statement.
