        ) on October 15, 2031 and to pay interest thereon from October 8, 2021 or from the most recent Interest Payment Date to which interest has been paid or made available for payment, semi-annually on April 15 and October 15 in each year, commencing
        April 15, 2022, and at the Maturity thereof, at the rate of 2.625% per annum, until the principal hereof is paid or made available for payment.  The interest so payable, and punctually paid or made available for payment, on any Interest Payment
        Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the March 31 or

        Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid in any other lawful manner not inconsistent with the
        requirements of any securities exchange on which these Securities may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

        Security Register; and provided, further, that if this Security is a Global Security,
        payment may be made pursuant to the Applicable Procedures of the Depositary as permitted in said Indenture.

      Reverse of Note

      

      

      This Security is one of a duly authorized issue of securities of the Issuers (herein called the “Securities”), issued and to be issued in one or
        more series under a Senior Debt Indenture, dated as of May 26, 2016 (herein called the “Indenture”, which term shall have the meaning assigned to it in such instrument), among each of the Issuers and The Bank of New York Mellon, as Trustee (herein
        called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Issuers,
        the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered.  This Security is one of the series designated on the face hereof initially limited in aggregate principal
        amount to $           .

       

      

      Prior to July 15, 2031 (the date that is three months prior to the scheduled maturity of the Securities) (the “Par Call Date”), the Securities of
        this series are subject to redemption upon not less than 10 days’ nor more than 60 days’ notice, at any time, as a whole or in part, at the election of the Issuers, at a redemption price (“Redemption Price”) equal to the greater of:

       

      

      
        
          
            	 	
                    (i)

                  	
                    100% of the principal amount of the Securities to be redeemed; or

                  


          

        

         

          

      

      
        
          	 	
                  (ii)

                	
                  the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any such portion of such payments of interest accrued as of
                    the date of redemption), discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below), plus     basis points,

                


        

      

       

      

      plus in each case, accrued and unpaid interest to, but excluding, the date of redemption.

       

      

      On or after the Par Call Date, the Securities of this series are subject to redemption upon not less than 10 days’ nor more than 60 days’ notice, at any time, as a
        whole or in part, at the election of the Issuers, at a Redemption Price equal to 100% of the principal amount of the Securities to be redeemed, plus accrued and unpaid interest to, but excluding, the date of redemption.

       

      

      Notwithstanding the foregoing, installments of interest on Securities of this series that are due and payable on interest payment dates falling on or prior to a
        redemption date will be payable on the interest payment date to the registered holders as of the close of business on the relevant record date according to the Indenture.

       

      

      “Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the
        remaining term of the Securities of this series to be redeemed that would be utilized, at the time of selection in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the
        remaining term of such Securities.

       

      

      “Comparable Treasury Price” means, with respect to any redemption date, (i) the average of four Reference Treasury Dealer Quotations for such
        redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Quotation Agent obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations, or (iii) if
        only one Reference Treasury Dealer Quotation is received, such quotation.

       

      

      
        
          


      

      
      “Quotation Agent” means the Reference Treasury Dealer appointed by the Company.

       

      

      “Reference Treasury Dealer” means (i) Jefferies LLC (or its affiliates that are Primary Treasury Dealers) and their respective successors; provided,
        however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company will substitute therefore another Primary Treasury Dealer, and (ii) any other Primary
        Treasury Dealer selected by the Company.

       

      

      “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by
        the Quotation Agent, 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 Quotation Agent by such reference treasury dealer at 5:00 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 annum equal to the semi-annual equivalent yield to maturity of the
        Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price of such redemption date.

       

      

      In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion
        hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

       

      

      
        2

        
          


      

      The Issuers will pay to any Holder of the Securities that is beneficially owned by a United States Alien Holder such additional amounts as may be
        necessary so that every net payment of principal of and interest on the Securities, after deduction or withholding for or on account of any present or future tax, assessment or other governmental charge imposed upon or as a result of such payment
        by the United States or any taxing authority thereof or therein, will not be less than the amount provided in the Securities to be then due and payable. We will not be required, however, to make any payment of additional amounts for or on account
        of:

       

      

      (1)       any tax, assessment or other governmental charge that would not have been imposed but for the existence of any present or former connection between such Holder or beneficial owner of such
          Securities (or between a fiduciary, settlor, beneficiary of, member or shareholder of, or possessor of a power over, such holder or beneficial owner, if such holder or beneficial owner is an estate, trust, partnership or corporation) and the
          United States, including, without limitation, such Holder or beneficial owner (or such fiduciary, settlor, beneficiary, member, shareholder or possessor), being or having been a citizen or resident or treated as a resident of the United States or
          being or having been engaged in trade or business or present in the United States or having or having had a permanent establishment in the United States;

       

        

      (2)              any tax, assessment or other governmental charge that would not have been imposed but for the presentation by the Holder of the Securities 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 thereof is duly provided for, whichever occurs later;

       

        

      (3)          any estate, inheritance, gift, sales, transfer, excise, personal property or similar tax, assessment or other governmental charge;

       

        

      (4)        any tax, assessment or other governmental charge imposed by reason of such Holder’s or beneficial owner’s past or present status as a passive foreign investment company, a controlled
          foreign corporation, a personal holding company or foreign personal holding company with respect to the United States, or as a corporation which accumulates earnings to avoid United States federal income tax;

       

        

      (5)        any tax, assessment or other governmental charge which is payable otherwise than by withholding from payment of principal of, or interest on, the Securities;

       

        

      (6)        any tax, assessment or other governmental charge required to be withheld by any paying agent from any payment of principal of, or interest on, the Securities if such payment can be made
          without withholding by any other paying agent;

       

        

      (7)         any tax, assessment or other governmental charge that is imposed by reason of a Holder’s or beneficial owner’s present or former status as (i) the actual or constructive owner of 10% or
          more of the total combined voting power of Jefferies Financial Group Inc. stock, as determined for purposes of Section 871(h)(3)(B) of the Internal Revenue Code of 1986, as amended (the “Code”), (or any successor provision) or (ii) a controlled
          foreign corporation that is related to us, as determined for purposes of Section 881(c)(3)(C) of the Code (or any successor provision);

       

      

      
        3

        
          


      

      (8)        any tax, assessment or other governmental charge (i) in the nature of a backup withholding tax, (ii) as a result of the failure to comply with information reporting requirements or (iii)
          imposed or required pursuant to Sections 1471 through 1474 of the Code and the U.S. Treasury Regulations promulgated thereunder (commonly referred to as “FATCA”), or imposed under any substantially similar successor legislation, any current or
          future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered
          into in connection therewith;

          

        

      (9)        any tax, assessment or other governmental charge imposed solely because the Holder or the beneficial owner of the Securities (i) is a bank purchasing Securities in the ordinary course of
          its lending business or (ii) is a bank that is neither (a) buying Securities for investment purposes nor (b) buying Securities for resale to a third party that either is not a bank or holding Securities for investment purposes only;

       

        

      (10)       any tax, assessment or other governmental charge imposed in whole or in part by reason of such Holder’s or beneficial owner’s past or present status as a corporation that accumulates
          earnings to avoid U.S. federal income tax or as a private foundation, a foreign private foundation or other tax-exempt organization; or

       

        

      (11)       any combinations of items identified in clauses (1) through (10) above.

       

        

      In addition, we will not be required to pay any additional amounts to any Holder or beneficial owner that is a fiduciary or partnership or other
        than the sole beneficial owner of the Securities to the extent that a beneficiary or settlor with respect to such fiduciary, or a member of such partnership or a beneficial owner thereof would not have been entitled to the payment of such
        additional amounts had such beneficiary, settlor, member or beneficial owner been the holder of the Securities.  In addition, if withholding of tax is required on the Securities linked to U.S. equities or equity indices under Treasury regulations
        promulgated under Section 871(m) of the Code, we will not be required to pay any additional amounts with respect to amounts withheld.

       

      

      The term “United States Alien Holder” means any corporation, partnership, individual or fiduciary that is, for United States federal income tax
        purposes, a foreign corporation, a nonresident alien individual, a nonresident fiduciary of a foreign estate or trust, or a foreign partnership one or more of the members of which is, for United States federal income tax purpose, a foreign
        corporation, a nonresident alien individual or a nonresident fiduciary of a foreign estate or trust.

      The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security or certain restrictive covenants and Events
        of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture.

       

      

      If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may
        be declared due and payable in the manner and with the effect provided in the Indenture.

       

      

      Unless the Issuers default in payment of the Redemption Price, on and after the redemption date, interest will cease to accrue on the Securities of
        this series or portions thereof called for redemption.  If less than all of the Securities of this series are to be redeemed, the Securities to be redeemed shall be selected in accordance with the procedures of DTC.

       

        

      
        4

        
          


      

      The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the
        Issuers and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Issuers and the Trustee with the consent of the Holders of a majority in principal amount of all Securities at the time
        Outstanding to be affected, considered together as one class for this purpose (such Securities to be affected may be Securities of the same or different series and, with respect to any series, may comprise fewer than all the Securities of such
        series).  The Indenture also contains provisions (i) permitting the Holders of a majority in principal amount of the Securities at the time Outstanding to be affected under the Indenture, considered together as one class for this purpose (such
        affected Securities may be Securities of the same or different series and, with respect to any particular series, may comprise fewer than all the Securities of such series), on behalf of the Holders of all Securities so affected, to waive
        compliance by the Issuers with certain provisions of the Indenture and (ii) permitting the Holder of a majority in principal amount of the Securities at the time Outstanding of any series to be affected under the Indenture (with each such series
        being considered separately for this purpose), on behalf of the Holders of all Securities of such series, to waive certain past defaults under the Indenture and their consequences.  Any such consent or waiver by the Holder of this Security shall be
        conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security 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 Security.

      

      

      As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with
        respect to the Indenture, or for the appointment of a receiver or trustee, or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities
        of this series, the Holders of not less than 51% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and
        offered the Trustee indemnity reasonably satisfactory to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request,
        and shall have failed to institute any such proceeding, for 90 days after receipt of such notice, request and offer of indemnity.  The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any
        payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

       

      

      If so provided pursuant to the terms of any specific Securities, the above-referenced provisions of the Indenture regarding the ability of Holders
        to waive certain defaults, or to request the Trustee to institute proceedings (or to give the Trustee other directions) in respect thereof, may be applied differently with regard to such Securities.

       

      

      No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of each of the
        Issuers, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

        Register, upon surrender of this Security for registration of transfer at the office or agency of the Issuers in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a
        written instrument of transfer in form satisfactory to the Issuers and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor,

        authorized denomination, as requested by the Holder surrendering the same.

       

      

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

       

      

      Prior to due presentment of this Security for registration of transfer, the Issuers, the Trustee and any agent of the Issuers or the Trustee may
