      provisions.

     

    

    
      
        


    

    
    THIS NINTH SUPPLEMENTAL INDENTURE is made as of the 2nd day of April, 2020, among AMERICAN FINANCIAL GROUP, INC., an Ohio corporation, Great American Insurance Group Tower, 301 East Fourth Street, Cincinnati, Ohio 45202 (the “Company”), and
      U.S. BANK NATIONAL ASSOCIATION, (formerly known as Star Bank, N.A.) a national banking association, as trustee (the “Trustee”).

     

    WITNESSETH:

     

    WHEREAS, the Company has entered into an indenture, dated as of November 12, 1997, as supplemented by this Ninth Supplemental Indenture (collectively,
      the “Indenture”) with U.S. Bank National Association, as trustee;

     

    WHEREAS, the Indenture is incorporated herein by this reference;

     

    WHEREAS, under the Indenture, a new series of Debt Securities may at any time be established by the Board of Directors of the Company in accordance with
      the provisions of the Indenture and the conditions, limitations and restrictions on the terms of such series may be established by a supplemental indenture executed by the Company and the Trustee;

     

    WHEREAS, the Company proposes to create under the Indenture a new series of Debt Securities;

     

    WHEREAS, additional Debt Securities of other series hereafter established, except as may be limited in the Indenture as at the time supplemented and
      modified, may be issued from time to time pursuant to the Indenture as at the time supplemented and modified, and that such series of Debt Securities hereafter established or any series of Debt Securities established prior to the date hereof shall
      not be subject to the provisions of this Ninth Supplemental Indenture unless expressly provided in the Board Resolution, supplemental indenture or other documentation, as permitted by the Indenture, establishing such series of Debt Securities; and

     

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

     

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

     

    ARTICLE I

    5.250% SENIOR NOTES

     

    Section 1.01          Establishment.  There is hereby established a new series of Debt Securities to be issued under the Indenture, to be designated as the Company’s 5.250% Senior Notes due April 2030 (the “Senior Notes”).

     

    There are to be authenticated and delivered Senior Notes, initially limited in aggregate principal amount of $300,000,000, and no further Senior Notes
      shall be authenticated and delivered except as provided by Section 2.1, 3.5, 3.6, 9.6 and 11.7 of the Indenture; provided further, 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, on the same tenor and terms and with the same CUSIP number as the Senior Notes (including, without limitation, rights to receive accrued and unpaid interest as the Senior Notes then outstanding), so that such further
      Senior Notes shall be consolidated with, form a single series with and increase the aggregate principal amount of the Senior Notes, provided that such further Senior Notes are fungible for U.S. federal income tax purposes with such previously issued
      Senior Notes.  The Senior Notes shall be issued in definitive fully registered form.

     

    

    
      
        


    

    The Senior Notes shall be issued in the form of one Global Security in substantially the form set out in Exhibit A hereto.  The U.S. Depositary with
      respect to the Senior Notes shall be The Depository Trust Company.

     

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

     

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

     

    Section 1.02          Definitions.  (a) 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 Indenture.

     

    “Final Maturity” means April 2, 2030.

     

    “Interest Payment Date” means April 2 and October 2 of each year.

     

    “Place of Payment” means New York, New York.

     

    “Regular Record Date” means March 15 and September 15; as the case may be, next preceding the relevant Interest Payment Date.

     

    Section 1.03          Payment of Principal and Interest.  The entire outstanding principal amount of the Senior Notes shall be due and payable, unless accelerated, redeemed or required to be repurchased pursuant to the Indenture, at Final
        Maturity.  The unpaid principal amount of the Senior Notes shall bear interest at the rate of 5.250% per annum until paid or duly provided for.  Interest shall be paid semi-annually in arrears on each Interest Payment Date, commencing October 2,
        2020, to the Person in whose name the Senior Notes are registered on the Regular Record Date for such Interest Payment Date, provided that interest payable at Final Maturity 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 3.7 of the 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 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 a payment of the interest payable on such date
      will be made on the next succeeding day that is a Business Day, except that, notwithstanding Section 1.13 of the Indenture, if such 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.  No interest will accrue due to any delay in payment on the amount so payable for the period from such Interest Payment Date to the date
      payment is made.

     

    

    
      - 2 -

      
        


    

    Payment of the principal and interest due at Final Maturity of the Senior Notes shall be made at the office or agency of the Company maintained for that
      purpose in the Place of Payment, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that, at the option of the Company, interest may be paid
      by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register; provided, further, that payment to the U.S. Depositary or any successor depositary may be made by wire transfer to the account
      designated by the U.S. Depositary or such successor depositary in writing.

     

    Section 1.04          Denominations.  The Senior Notes may be issued in denominations of $2,000.00, or any integral multiples of $1,000 in excess thereof.

     

    Section 1.05          Global Securities.  The Senior Notes will be issued in the form of one or more Global Securities registered in the name of the U.S. Depositary or its nominee.  Except under the limited circumstances described below,
        Senior Notes represented by the Global Security will not be exchangeable for, and will not otherwise be issuable as, Senior Notes in definitive form.  The Global Securities described above may not be transferred except as a whole by the U.S.
        Depositary to a nominee of such U.S. Depositary or by a nominee of such U.S. Depositary to such depositary or another nominee of such U.S. Depositary or by such U.S. Depositary or any other such nominee to a successor U.S. Depositary or a nominee
        of such successor U.S. Depositary.

     

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

     

    A Global Security shall be exchangeable for Senior Notes registered in the names of Persons other than the U.S. Depositary or its nominee only as
      provided by Section 3.5 of the Indenture.  Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Senior Notes registered in such names as the U.S. Depositary shall direct.

     

    Section 1.06          Redemption at the Option of the Company.

     

    (A)          As used in this Section
          1.06:

     

    “Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having an actual
      or interpolated maturity comparable to the remaining term (“Remaining Life”) of the Senior Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate
      debt securities of comparable maturity to the remaining term of such Senior Notes.

     

    “Comparable Treasury Price” means, with respect to any redemption date, the average of the two Reference Treasury Dealer Quotations
      for such redemption date.

     

    “Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company.

     

    “Reference Treasury Dealer” means each of J.P. Morgan Securities LLC, BofA Securities, Inc., and Wells Fargo Securities, LLC, and
      their respective successors; provided, however, that if any of the foregoing or their successors cease to be a primary U.S. Government securities dealer (each, a “Primary Treasury Dealer”), the Company will substitute therefor another such Primary
      Treasury Dealer.

     

    

    
      - 3 -

      
        


    

    “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as
      determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 3:30 p.m., New York City
      time, on the third business day preceding such redemption date.

     

    “Treasury Rate” means, with respect to any redemption date, the rate per year equal to:

     

    
      
        	

                 	(1)	
                the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15” or
                  any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption
                  “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue; provided that, if no maturity is within three months before or after the Remaining Life of the Senior Notes to be redeemed, yields for the
                  two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Treasury Rate shall be interpolated from those yields on a straight line basis, rounding to the nearest month; or

              


      

    

     

    
      
        	

                 	(2)	
                if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the
                  semiannual equivalent yield to maturity or interpolated maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable
                  Treasury Price for such redemption date.

              


      

    

     

    The Treasury Rate will be calculated on the third business day preceding the redemption date. As used in the immediately preceding sentence and in the
      definition of “Reference Treasury Dealer Quotations” above, the term “business day” means any day that is not a Saturday, Sunday or other day on which commercial banks in New York City are authorized or required by law to remain closed.

     

    (B)          Prior to January 2, 2030 (the date that is three months prior to the Final Maturity), the Senior Notes may be redeemed, in whole or in part, at the
          Company’s option, at any time or from time to time, on notice given not more than 60 days, if the Senior Notes are being redeemed in full, or 45 days, if the Senior Notes are being redeemed in part, nor less than 30 days, prior to the date of
          redemption, at a redemption price equal to the greater of (i) 100% of the principal amount of any Senior Notes to be redeemed; or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on any Senior Notes
          to be redeemed (exclusive of interest accrued to the date of redemption) discounted to the date of redemption on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the then current Treasury Rate plus 50 basis
          points.

     

    (C)          On or after January 2, 2030 (the date that is three months prior to the Final Maturity), the Senior Notes may be redeemed, in whole or in part, at the
          Company’s option, at any time or from time to time, on notice given not more than 60 days, if the Senior Notes are being redeemed in full, or 45 days, if the Senior Notes are being redeemed in part, nor less than 30 days, prior to the date of
          redemption, at a redemption price equal to 100% of the principal amount of any Senior Notes to be redeemed.

     

        

    
      - 4 -

      
        


    

    (D)          If the Company redeems any Senior Notes
          pursuant to Paragraphs (B) or (C) of this Section 1.06, the Company will pay accrued and unpaid interest on the principal amount of any Senior Note being redeemed to, but excluding, the redemption date.

     

    (E)          The full defeasance and covenant
          defeasance provisions of the Indenture relating to the Company’s obligations in connection with the Debt Securities will apply to the Senior Notes.

     

    Section 1.07          Governing Law.  Section 1.12 of the Indenture is hereby amended and restated to read in its entirety as follows:

     

    “SECTION 1.12     Governing Law.

     

    THIS INDENTURE AND THE DEBT SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO THE
      CONFLICTS OF LAW RULES OF SUCH STATE.  THIS INDENTURE IS SUBJECT TO THE PROVISIONS OF THE TRUST INDENTURE ACT OF 1939, AS AMENDED, THAT ARE REQUIRED TO BE PART OF THIS INDENTURE AND SHALL, TO THE EXTENT APPLICABLE, BE GOVERNED BY SUCH PROVISIONS.”

     

    Section 1.08          Registration, Registration of Transfer and Exchange.  Section 3.5 of the Indenture is hereby amended and restated to read in its entirety as follows:

     

    “SECTION 3.5     Registration, Registration of Transfer and Exchange.  The Company shall keep or cause to be kept for the Debt Securities of each series a register (the register maintained in such office being herein sometimes referred to
          as the “Debt Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration, registration of transfer and exchange of Debt Securities.  The Trustee is hereby initially
          appointed “Debt Security Registrar” for such purposes.

     

    Upon surrender for registration of transfer of any Debt Security of any particular series at the office or agency of the Company in a Place of Payment
      for that series, the Company shall execute, and the Trustee for the Debt Securities of each series shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Debt Securities of any authorized
      denominations, and of a like Stated Maturity and of a like series and aggregate principal amount and with like terms and conditions.

     

    Except as set forth below, at the option of the Holder, Debt Securities of any particular series may be exchanged for other Debt Securities of any
      authorized denominations, and of a like Stated Maturity and of a like series and aggregate principal amount and with like terms and conditions, upon surrender of the Debt Securities to be exchanged at such office or agency.  Whenever any Debt
      Securities are so surrendered for exchange, the Company shall execute, and the Trustee for such Debt Securities shall authenticate and deliver, the Debt Securities which the Holder making the exchange is entitled to receive.

     

    All Debt Securities issued upon any registration of transfer or exchange of Debt Securities shall be the valid obligations of the Company, evidencing the
      same debt, and entitled to the same benefits under this Indenture, as the Debt Securities surrendered upon such registration of transfer or exchange.

     

    

    
      - 5 -

      
        


    

    Every Debt Security presented or surrendered for registration of transfer or exchange shall (if so required by the Company or the Trustee for such Debt
      Security) be duly endorsed, or be accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Debt Security Registrar for such series duly executed by the Holder thereof or his attorney duly authorized in
      writing.

     

    No service charge shall be made for any registration of transfer or exchange of Debt Securities, but the Company may require payment of a sum sufficient
      to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Debt Securities, other than exchanges pursuant to Section 3.4, 9.6, 11.3 or 11.7 not involving any transfer.

     

    Notwithstanding any other provision of this Section, unless and until it is exchanged in whole or in part for Debt Securities in definitive form, a
      Global Security representing all or a portion of the Debt Securities of a series may not be transferred except as a whole by the U.S. Depositary for such series to a nominee of such U.S. Depositary or by a nominee of such U.S. Depositary to such
      depositary or another nominee of such U.S. Depositary or by such U.S. Depositary or any other such nominee to a successor U.S. Depositary for such series or a nominee of such successor U.S. Depositary.

     

    If at any time the U.S. Depositary for the Debt Securities of a series notifies the Company that it is unwilling or unable to continue as U.S. Depositary
      for the Debt Securities of such series or if at any time the U.S. Depositary for Debt Securities of such series shall no longer be a clearing agency registered and in good standing under the Exchange Act or other applicable statute or regulation, the
      Company shall appoint a successor U.S. Depositary for the Debt Securities of such series.  If a successor U.S. Depositary for the Debt Securities is not appointed by the Company within 90 days after the Company receives such notice or becomes aware
      of such condition, the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Debt Securities of such series, will authenticate and deliver, Debt Securities of such series in
      definitive form in an aggregate principal amount equal to the principal amount of the Global Security or Securities representing such series in exchange for such Global Security or Securities.

     

    The Company may at any time and in its sole discretion determine that the Debt Securities of any series issued in the form of one or more Global
      Securities shall no longer be represented by such Global Security or Securities.  In such event, the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Debt Securities of such
      series, will authenticate and deliver, Debt Securities of such series in definitive form and in an aggregate principal amount equal to the principal amount of the Global Security or Securities representing such series in exchange for such Global
      Security or Securities.

     

    If the Debt Securities of any series shall have been issued in the form of one or more Global Securities and if an Event of Default with respect to the
      Debt Securities of such series shall have occurred and be continuing, the Company will promptly execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Debt Securities of such series, will
      authenticate and deliver Debt Securities of such series in definitive form and in an aggregate principal amount equal to the principal amount of the Global Security or Securities representing such series in exchange for such Global Security or
      Securities.

     

    The U.S. Depositary for such series of Debt Securities may surrender a Global Security for such series of Debt Securities in exchange in whole or in part
      for Debt Securities of such series of like tenor and terms and in definitive form on such terms as are acceptable to the Company and such U.S.  Depositary.  Thereupon, the Company shall execute and the Trustee shall authenticate and deliver, without
      charge:

     

    

    
      - 6 -

      
        


    

    (1)           to each Person
          specified by the U.S. Depositary a new Debt Security or Securities of the same series, of like tenor and terms and of any authorized denomination as requested by such Person in an aggregate principal amount equal to and in exchange for such
          Person’s beneficial interest in the Global Security; and

     

    (2)           to the U.S.
          Depositary a new Global Security in a denomination equal to the difference, if any, between the principal amount of the surrendered Global Security and the aggregate principal amount of the Debt Securities delivered to Holders thereof.

     

    Upon the exchange of a Global Security for Debt Securities in definitive form, such Global Security shall be canceled by the Trustee.  Definitive Debt
      Securities issued in exchange for a Global Security pursuant to this Section shall be registered in such names and in such authorized denominations as the U.S. Depositary for such Global Security, pursuant to instructions from its direct or indirect
      participants or otherwise, shall instruct the Trustee.  The Trustee shall deliver such definitive Debt Securities to the Persons in whose names such Debt Securities are so registered.”

     

    Section 1.09          Title; Payment and Terms. The last paragraph of Section 3.1 of the Indenture is hereby amended
          and restated to read in its entirety as follows:

     

    “All Debt Securities of any particular series
        shall be substantially identical except as to denomination, rate of interest, Stated Maturity and the date from which interest, if any, shall accrue, and except as may otherwise be provided in or pursuant to such Board Resolution relating thereto. 
        The terms of such Debt Securities, as set forth above, may be determined by the Company from time to time if so provided in or established pursuant to the authority granted in a Board Resolution.  Any of the terms of the Debt Securities, as set
        forth above, may be made dependent upon facts ascertainable outside the Board Resolution provided that the manner in which said facts shall operate upon the terms is set forth in the Board Resolution.  All Debt Securities of any one series need not
        be issued at the same time, and unless otherwise provided, a series may be reopened, without notice to or the consent of the registered holders of such Debt Securities, for issuances of additional Debt Securities of such series.  Such additional
        Debt Securities will rank pari passu with the outstanding Debt Securities of such series in all material respects, or in all respects except for the issue date and public offering price or payment of interest accruing prior to the issue date of such additional Debt
        Securities or except for the first payment of interest following the issue date of such additional Debt Securities, and so that such additional Debt Securities may be consolidated and form a single series with the outstanding Debt Securities of
        such series and have the same terms as to status, redemption or otherwise as the outstanding Debt Securities of such series; provided that such additional Debt Securities are fungible for U.S. federal income tax purposes with such previously issued
        Debt Securities”

     

    Section 1.10          Mutilated, Destroyed, Lost and Stolen Debt Securities.  Section 3.6 of the Indenture is hereby amended and restated to read in its entirety as follows:

     

    “SECTION 3.6     Mutilated, Destroyed, Lost and Stolen Debt Securities.  If (i) any mutilated Debt Security is surrendered to the Trustee for such Debt Security, or the Company and the Trustee for a Debt Security receive evidence to their
          satisfaction of the destruction, loss or theft of any Debt Security, and (ii) there is delivered to the Company, the Debt Security Registrar and such Trustee such security or indemnity as may be reasonably required by them to save each of them
          and any agent of either of them harmless, then, in the absence of notice to the Company or such Trustee that such Debt Security has been acquired by a bona fide purchaser, the Company shall execute and upon its request such Trustee shall
          authenticate and deliver, in lieu of any such destroyed, lost or stolen Debt Security or in exchange for such mutilated Debt Security, a new Debt Security of the same series and in a like principal amount and of a like Stated Maturity and with
          like terms and conditions and bearing a number not contemporaneously outstanding.

     

        

    
      - 7 -

      
        


    

    In case any such mutilated, destroyed, lost or stolen Debt Security has become or is about to become due and payable, the Company in its discretion may,
      instead of issuing a new Debt Security, pay such Debt Security (without surrender thereof except in the case of a mutilated Debt Security) if the applicant for such payment shall furnish to the Company, the Debt Security Registrar and the Trustee for
      such Debt Security such security or indemnity as may be reasonably required by them to save each of them harmless, and in case of destruction, loss or theft, evidence reasonably satisfactory to the Company and such Trustee and any agent of either of
      them of the destruction, loss or theft of such Debt Security and the ownership thereof.

     

    Upon the issuance of any new Debt Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other
      governmental charge that may be imposed in relation thereto and any other expenses (including all fees and expenses of the Trustee and the Debt Security Registrar for such Debt Security) connected therewith.

     

    Every new Debt Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Debt Security or in exchange for any
      mutilated Debt Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Debt Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of
      this Indenture equally and proportionately with any and all other Debt Securities of the same series, duly issued hereunder.

     

    The provisions of this Section are exclusive and shall preclude (to the extent lawful) the assertion of any Holder of all other rights and remedies with
      respect to the replacement or payment of mutilated, destroyed, lost or stolen Debt Securities.”

     

    Section 1.11          Events of Default.  Section 5.1 of the Indenture is hereby amended and restated to read in its entirety as follows:

     

    “SECTION 5.1  Events of Default.  “Event of Default” wherever used herein with respect to
      any particular series of Debt Securities, unless otherwise specified in the Debt Security or the Board Resolution with respect to that series of Debt Securities, means any one of the following events (whatever the reason for such Event of Default and
      whether it shall be voluntary or involuntary or be effected by operation of law pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

     

    (1)          default in the payment of any installment
          of interest upon any Debt Security of that series when it becomes due and payable, and continuance of such default for a period of 30 days; or

     

    (2)          default in the payment of the principal of
          (or premium, if any, on) any Debt Security of that series at its Maturity; or

     

    (3)          default in the performance of, or breach
          of, any covenant or warranty of the Company in respect of any Debt Security of that series contained in this Indenture or in such Debt Securities (other than a covenant or warranty a default in whose performance or whose breach is elsewhere in
          this Section specifically dealt with or which expressly has been included in this Indenture solely for the benefit of Debt Securities of a series other than that series) or in the applicable Board Resolution under which such series is issued as
          contemplated by Section 3.1 and continuance of such default or breach for a period of 60 days after there has been given, by registered or certified mail, to the Company by the Trustee for the Debt Securities of such series or to the Company and
          such Trustee by the Holders of at least 25% in principal amount of the Outstanding Debt Securities of that series a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of

          other series of Debt Securities or as defined in any mortgage, indenture, security agreement or other instrument under which there may be issued, or by which there may be secured or evidenced, any Indebtedness of the Company for money borrowed in
          excess of $10 million principal amount, whether such Indebtedness now exists or shall hereafter be created, shall happen and, if such Indebtedness is not already matured in accordance with its terms, shall result in such Indebtedness becoming or
          being declared due and payable prior to the date on which it would otherwise become due and payable, and such acceleration shall not have been rescinded or annulled or such Indebtedness shall not have been discharged, in either case, within a
          period of ten days after there has been given, by registered or certified mail in the manner set forth in Section 1.5, to the Company by the Trustee for the Debt Securities of that particular series referred to in the first clause of this Section
          5.1 or to the Company and such Trustee by the Holders of at least 25% in principal amount of the Outstanding Debt Securities of that particular series referred to in the first clause of this Section 5.1 a written notice specifying such event of
          default and requiring the Company to cause such acceleration to be rescinded or annulled or to cause such Indebtedness to be discharged and stating that such notice is a “Notice of Default” hereunder; provided, that if prior to the entry of
          judgment in favor of the Trustee, such default under such indenture or instrument shall be remedied or cured by the Company or waived by the holders of such Indebtedness, then the Event of Default hereunder shall be deemed likewise to have been
          remedied, cured or waived; and provided, further, however, that, subject to the provisions of Sections 6.1 and 6.2, such Trustee shall not be deemed to have knowledge of such default unless either (A) a Responsible Officer of such Trustee
          assigned to its Corporate Trust Office shall have actual knowledge of such default or (B) the Trustee shall have received written notice thereof from the Company, from the Holders of 10% or more in principal amount of the Outstanding Debt
          Securities of such other series, from the holder of any such Indebtedness or from the trustee under any such mortgage, indenture, security agreement or other instrument; or

     

    (5)          the entry against the Company of one or
          more judgments, decrees or orders by a court having jurisdiction in the premises from which no appeal may be or is taken for the payment of money, either individually or in the aggregate, in excess of $10 million and the continuance of such
          judgment, decree or order unsatisfied and in effect for any period of 60 consecutive days without a stay of execution and there has been given, by registered or certified mail in the manner set forth in Section 1.5, to the Company by the Trustee
          for the Debt Securities of such series or to the Company and such Trustee by the Holders of at least 25% in principal amount of the Outstanding Debt Securities of such series a written notice specifying such entry and continuance of such
          judgment, decree or order and stating that such notice is a “Notice of Default” hereunder; provided, however, that subject to the provisions of Sections 6.1 and 6.2, such Trustee shall not be deemed to have knowledge of such entry and continuance
          of such judgment, decree or order unless either (A) a Responsible Officer of such Trustee assigned to its Corporate Trust Office shall have actual knowledge thereof or (B) the Trustee shall have received written notice thereof from the Company or
          from the Holders of 10% or more in principal amount of the Outstanding Debt Securities of such series; or

          any other relief under any bankruptcy, insolvency, reorganization, liquidation, dissolution, arrangement, composition, readjustment of debt or other similar act or law of any jurisdiction, domestic or foreign, now or hereafter existing; or the
          Company shall apply for a receiver, custodian or trustee (other than any trustee appointed as a mortgagee or secured party in connection with the issuance of indebtedness for borrowed money of the Company) of it or for all or a substantial part
          of its property; or the Company shall make a general assignment for the benefit of creditors; or the Company shall take any corporate action in furtherance of any of the foregoing; or

    Section 1.12          Acceleration of Maturity; Rescission and Annulment.  Section 5.2 of the Indenture is hereby amended and restated to read in its entirety as follows:

     

    “SECTION 5.2 Acceleration of Maturity; Rescission and Annulment.  If an Event of Default (other than an Event of Default specified in Section 5.1(6) or
      (7)) with respect to any particular series of Debt Securities occurs and is continuing, then and in every such case either the Trustee for the Debt Securities of such series or the Holders of not less than 25% in principal amount of the Outstanding
      Debt Securities of that series may declare the entire principal amount (or, in the case of Discounted Debt Securities, such lesser amount as may be provided for in the terms of that series) of all the Debt Securities of that series to be due and
      payable immediately, by a notice in writing to the Company (and to such Trustee if given by Holders), and upon any such declaration of acceleration such principal or such lesser amount, as the case may be, together with accrued interest and all other
      amounts owing hereunder, shall become immediately due and payable, without presentment, demand, protest or notice of any kind, all of which are hereby expressly waived.

     

    If an Event of Default specified in Sections 5.1(6) or (7) occurs and is continuing, such principal or such lesser amount, as the case may be, together
      with accrued interest and all other amounts owing hereunder, on the Debt Securities of that series shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

     

    At any time after such a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained by the
      Trustee for the Debt Securities of any series as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Debt Securities of that series, by written notice to the Company and such Trustee, may rescind and
      annul such declaration and its consequences if:

     

    (1)          the Company has paid or deposited with
          such Trustee a sum sufficient to pay

     

    (A)          all overdue interest on all Debt
          Securities of that series;

     

    (B)          the principal of (and premium, if any, on)
          any Debt Securities of that series which have become due otherwise than by such declaration of acceleration and interest thereon from the date such principal became due at a rate per annum equal to the rate borne by the Debt Securities of such
          series (or, in the case of Discounted Debt Securities, the Debt Securities’ Yield to Maturity), to the extent that the payment of such interest shall be legally enforceable;

          interest is lawful, interest upon overdue interest at a rate per annum equal to the rate borne by the Debt Securities of such series (or, in the case of Discounted Debt Securities, the Debt Securities’ Yield to Maturity);

     

    (D)          all sums paid or advanced by such Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of such Trustee,
      its agents and counsel and all other amounts due to such Trustee under; and

     

    (2)          all Events of Default with respect to the
          Debt Securities of such series, other than the nonpayment of the principal of Debt Securities of that series which has become due solely by such acceleration, have been cured or waived as provided in Section 5.13.  No such rescission shall affect
          any subsequent default or impair any right consequent thereon.”

          Trustee shall become effective and such successor Trustee without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor
          Trustee, such retiring Trustee shall, upon payment of its reasonable charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and
          deliver to such successor Trustee all property and money held by such retiring Trustee hereunder, subject to the lien provided for in Section 6.7.”

          institute suit for the enforcement of any such payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date); or

          Section or Section 5.13 or 10.7, except to increase any such percentage or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Debt Security affected thereby; provided,
          however, that this clause shall not be deemed to require the consent of any Holder of a Debt Security with respect to changes in the references to “the Trustee” and concomitant changes in this Section and Section 10.7, or the deletion of this
          proviso, in accordance with the requirements of Section 6.9, 6.11(b) and 9.1(6); or

          any, or interest on, any Debt Security payable in anything other than United States Dollars.

      of the Holders of Debt Securities of any other series.

     

    It shall not be necessary for any Act of Holders under this Section to approve the particular form of any proposed supplemental indenture, but it shall

      preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders; and provided, further, however, that the foregoing shall not prohibit a
      sale, transfer or conveyance of a Subsidiary or any of its assets in compliance with the terms of this Indenture.”

    American Financial Group, Inc.

     

    5.250% Senior Notes Due April 2030

     

    Principal Amount Per Senior Note: $2,000 and Integral Multiples of $1,000 in Excess Thereof

     

    American Financial Group, Inc., an Ohio corporation (hereinafter called the “Company”, which term includes any successor corporation under the Indenture
      referred to below), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal amount of each Senior Note evidenced hereby (Three Hundred Million Dollars ($300,000,000) in the aggregate) on April 2, 2030, and
      to pay interest thereon from April 2, 2020 or from the most recent date to which interest has been paid or duly provided semi-annually on April 2 or October 2 in each year (each, an “Interest Payment Date”), commencing October 2, 2020, at the rate of
      5.250% per annum, until the principal amount of each Senior Note evidenced hereby is paid or duly made available for payment. Interest on the Senior Notes shall be calculated on the basis of a 360-day year consisting of twelve 30-day months. The
      interest so payable and punctually paid or duly provided for on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this certificate is registered at the close of business on the Regular Record Date for
      such interest, which shall be March 15 and September 15 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Any such interest which is payable, but is not punctually paid or duly provided for, on any
      Interest Payment Date shall forthwith cease to be payable to the registered Holder hereof on the relevant Regular Record Date by virtue of having been such Holder, and may be paid to the Person in whose name this certificate is registered at the
      close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to each Person in whose name a certificate evidencing Senior Notes (defined below) is registered not less
      than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Senior Notes may be listed, and upon such notice as may be required
      by such exchange, all as more fully provided in such Indenture.

     

    

    
      A-1

      
        


    

    Payment of the principal of and the interest on the Senior Notes evidenced hereby will be made at the office or agency of the Company maintained for that
      purpose in the Place of Payment, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that, at the option of the Company, interest may be paid
      by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register; provided, further, that payment to The Depository Trust Company (“DTC”) or any successor depositary may be made by wire transfer to
      the account designated by DTC or such successor depositary in writing.

     

    This certificate evidences part of a duly authorized issue of unsecured and unsubordinated indebtedness of the Company (the “Debt Securities”) issued and
      to be issued in one or more series under an Indenture dated as of November 12, 1997 (herein called, together with all indentures supplemental thereto, the “Indenture”) between the Company and U.S. Bank National Association, as Trustee (herein called
      the “Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, obligations, duties
      and immunities thereunder of the Company, the Trustee and the Holders of the Debt Securities, and of the terms upon which the Debt Securities are, and are to be, authenticated and delivered. This certificate evidences Debt Securities of the series
      designated on the face hereof (each, a “Senior Note”), limited to $300,000,000; provided, 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, on the same
      tenor and terms and with the same CUSIP number as the Senior Notes (including, without limitation, rights to receive accrued and unpaid interest as the Senior Notes then outstanding), so that such further Senior Notes shall be consolidated with, form
      a single series with and increase the aggregate principal amount of the Senior Notes, provided that such further Senior Notes are fungible for U.S. federal income tax purposes with such previously issued Senior Notes.

     

    Prior to January 2, 2030 (the date that is three months prior to the Final Maturity), the Senior
      Notes may be redeemed, in whole or in part, at the Company’s option, at any time or from time to time, on notice given not more than 60 days, if the Senior Notes are being redeemed in full, or 45 days, if the Senior Notes are being redeemed in part,
      nor less than 30 days, prior to the date of redemption, at a redemption price equal to the greater of (i) 100% of the principal amount of any Senior Notes to be redeemed; or (ii) the sum of the present values of the remaining scheduled payments of
      principal and interest on any Senior Notes to be redeemed (exclusive of interest accrued to the date of redemption) discounted to the date of redemption on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the then
      current Treasury Rate plus 50 basis points.

     

    “Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having an actual
      or interpolated maturity comparable to the remaining term (“Remaining Life”) of the Senior Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate
      debt securities of comparable maturity to the remaining term of such Senior Notes.

     

    

    
      A-2

      
        


    

    “Comparable Treasury Price” means, with respect to any redemption date, the average of the two Reference Treasury Dealer Quotations
      for such redemption date.

     

    “Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company.

     

    “Reference Treasury Dealer” means each of J.P. Morgan Securities LLC, BofA Securities, Inc., and Wells Fargo Securities, LLC, and
      their respective successors; provided, however, that if any of the foregoing or their successors cease to be a primary U.S. Government securities dealer (each, a “Primary Treasury Dealer”), the Company will substitute therefor another such Primary
      Treasury Dealer.

     

    “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as
      determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 3:30 p.m., New York City
      time, on the third business day preceding such redemption date.

     

    “Treasury Rate” means, with respect to any redemption date, the rate per year equal to:

     

    
      
        	

                 	(1)	
                the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15” or
                  any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption
                  “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue; provided that, if no maturity is within three months before or after the Remaining Life of the Senior Notes to be redeemed, yields for the
                  two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Treasury Rate shall be interpolated from those yields on a straight line basis, rounding to the nearest month; or

              


      

    

     

    
      
        	

                 	(2)	
                if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the
                  semiannual equivalent yield to maturity or interpolated maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable
                  Treasury Price for such redemption date.

              


      

    

     

    The Treasury Rate will be calculated on the third business day preceding the redemption date. As used in the immediately preceding sentence and in the
      definition of “Reference Treasury Dealer Quotations” above, the term “business day” means any day that is not a Saturday, Sunday or other day on which commercial banks in New York City are authorized or required by law to remain closed.

     

    On or after January 2, 2030 (the date that is three months prior to the Final Maturity), the
      Senior Notes may be redeemed, in whole or in part, at the Company’s option, at any time or from time to time, on notice given not more than 60 days, if the Senior Notes are being redeemed in full, or 45 days, if the Senior Notes are being redeemed in
      part, nor less than 30 days, prior to the date of redemption, at a redemption price equal to 100% of the principal amount of any Senior Notes to be redeemed.

     

    

    
      A-3

      
        


    

    If the Company redeems any Senior Notes pursuant to the foregoing paragraphs, the Company will pay accrued and unpaid interest on the principal amount of
      any Senior Note being redeemed to, but excluding, the redemption date.

    

       

    The full defeasance and covenant defeasance provisions of the Indenture relating to the Company’s obligations in connection with the Debt Securities will
      apply to the Senior Notes.

     

    Except as provided above, the Senior Notes are not redeemable by the Company prior to maturity and are not subject to any sinking fund. If an Event of
      Default with respect to the Senior Notes shall occur and be continuing, the principal amount of the Senior Notes shall be immediately, or may be declared, as appropriate, due and payable in the manner and with the effect 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 Securities of each series issued 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 Securities
      at the time Outstanding of each series affected thereby. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities of any series at the time Outstanding, on behalf of the
      Holders of all Securities of such series, to waive compliance by the 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 certificate
      shall be conclusive and binding upon such Holder and upon all future Holders of this certificate and of any Senior Notes evidenced by a certificate issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or
      not notation of such consent or waiver is made upon this certificate.

     

    No reference herein to the Indenture and no provision of this certificate 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 the Senior Notes evidenced by this certificate, at the times, place and rate, and in the coin or currency, herein and in the Indenture prescribed.

     

    As provided in the Indenture and subject to certain limitations set forth therein and in this certificate, the transfer of the Senior Notes evidenced by
      this certificate may be registered on the Security Register upon surrender of this certificate for registration of transfer at the office or agency of the Company maintained for the purpose in any place where the principal of and interest on the
      Senior Notes are payable, duly endorsed by, or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or by his attorney duly authorized in
      writing, and thereupon one or more new certificates evidencing Senior Notes of authorized denominations, and of a like series and aggregate principal amount, and with like terms and conditions will be issued to the designated transferee or
      transferees.

     

    The Senior Notes are issuable only in registered form without coupons in denominations of $2,000.00, or any integral multiples of $1,000 in excess
      thereof, all as more fully provided in the Indenture. As provided in the Indenture, and subject to certain limitations set forth in the Indenture, and in this certificate, this certificate is exchangeable for a like aggregate principal amount of
      Senior Notes of this series in different authorized denominations, as requested by the Holders surrendering the same.

     

    

    
      A-4

      
        


    

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

     

    Prior to due presentment of this certificate for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat
      the Person in whose name this certificate is registered as the owner of the Senior Notes evidenced hereby for all the purpose of receiving payment of principal of and (subject to Section 3.7 of the Indenture) interest, if any, on these Senior Notes
      and for all purposes whatsoever, whether or not such Senior Notes be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

     

    This certificate shall be governed by and construed in accordance with the laws of the State of New York without regard to the conflicts of laws rules of
      such state.

     

    All terms used in this certificate which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

     

    Unless the certificate of authentication hereon has been executed by or on behalf of the Trustee under the Indenture by the manual signature of one of
      its authorized signatories, this certificate shall not be entitled to any benefits under the Indenture or be valid or obligatory for any purpose.

     

    IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed under its corporate seal.
