    This
      Note
      is a Global Security within the meaning of the Indenture hereinafter referred
      to
      and is registered in the name of the Depository named below or a nominee of
      the
      Depository. This Note is not exchangeable for Notes registered in the name
      of a
      Person other than the Depository or its nominee except in the limited
      circumstances described herein and in the Indenture, and no transfer of this
      Note (other than a transfer of this Note as a whole by the Depository to a
      nominee of the Depository or by a nominee of the Depository to the Depository
      or
      another nominee of the Depository) may be registered except in the limited
      circumstances described herein.

    


    Unless
      this certificate is presented by an authorized representative of The Depository
      Trust Company, a New York corporation (the "Depository"), to the Company or
      its
      agent for registration of transfer, exchange, or payment, and any certificate
      issued is registered in the name of Cede & Co. or in such other name as is
      requested by an authorized representative of the Depository (and any payment
      is
      made to Cede & Co. or to such other entity as is requested by an authorized
      representative of the Depository), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF
      FOR
      VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered
      owner hereof, Cede & Co., has an interest herein.

    CITIGROUP
      INC., a Delaware corporation (the "Company", which term includes any successor
      Person under the Indenture), for value received, hereby promises to pay to
      Cede
& Co., or registered assigns, the principal sum of $___________ on March 5,
      2038 and
      to
      pay interest thereon from and including March 5, 2008 or from the most recent
      Interest Payment Date to which interest has been paid or duly provided for,
      semi-annually, on March 5 and September 5 of each year, commencing September
      5,
      2008, at the rate of 6.875% per annum, until the principal hereof is paid or
      made available for payment. The interest so payable, and punctually paid or
      duly
      provided for, on any Interest Payment Date will, as provided in the Indenture,
      be paid to the Person in whose name this Note is registered at the close of
      business on the Record Date for such interest, which shall be the February
      15
      and August 15 (whether or not a Business Day) immediately preceding such
      Interest Payment Date.

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    


    Any
      such
      interest not so punctually paid or duly provided for will forthwith cease to
      be
      payable to the holder on such Record Date and may either be paid to the Person
      in whose name this Note is registered at the close of business on a subsequent
      Record Date, such subsequent Record Date to be not less than five days prior
      to
      the date of payment of such defaulted interest, notice whereof shall be given
      to
      holders of Notes of this series not less than 15 days prior to such subsequent
      Record Date, or be paid at any time in any other lawful manner not inconsistent
      with the requirements of any securities exchange on which the Notes of this
      series may be listed, and upon such notice as may be required by such exchange,
      all as more fully provided in the Indenture.

    


    Interest
      hereon will be calculated on the basis of a 360-day year comprised of twelve
      30-day months.

    


    If
      either
      an Interest Payment Date or the Maturity of the Notes falls on a day that is
      not
      a Business Day, such Interest Payment Date or Maturity will be the next
      succeeding Business Day. If a date for payment of interest or principal on
      the
      Notes falls on a day that is not a business day in the place of payment, such
      payment will be made on the next succeeding business day in such place of
      payment as if made on the date the payment was due. No interest will accrue
      on
      any amounts payable for the period from and after the due date for payment
      of
      such principal or interest. 

    


    For
      these
      purposes, “Business Day” means any day which is a day on which commercial banks
      settle payments and are open for general business in The City of New
      York.

    


    Payment
      of the principal of and interest on this Note will be made at the office or
      agency of the Trustee maintained for that purpose in The City of New
      York.

    


    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.

    


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

    This
      Note
      is one of a duly authorized issue of Securities of the Company (the "Notes"),
      issued and to be issued in one or more series under the Indenture, dated as
      of
      March 15, 1987 (as amended and supplemented to date, the "Indenture"), between
      the Company and The Bank of New York, as Trustee (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, duties and immunities thereunder
      of
      the Company, the Trustee and the holders of the Notes and of the terms upon
      which the Notes are, and are to be, authenticated and delivered. This Note
      is
      one of the series designated on the face hereof, initially limited in aggregate
      principal to $2,500,000,000.

    


    If
      an
      event of default (as defined in the Indenture) with respect to Notes of this
      series shall occur and be continuing, the principal of the Notes of this series
      may be declared due and payable in the manner and with the effect provided
      in
      the Indenture.

    


    The
      Indenture contains provisions for defeasance at any time of the entire
      indebtedness of this Note upon compliance by the Company with certain conditions
      set forth in Sections 11.03 and 11.04 thereof, which provisions apply to this
      Note.

    


    The
      Indenture contains provisions permitting the Company and the Trustee, without
      the consent of the holders of the Securities, to establish, among other things,
      the form and terms of any series of Securities issuable thereunder by one or
      more supplemental indentures, and, with the consent of the holders of not less
      than 66 2/3% in aggregate principal amount of Securities at the time outstanding
      which are affected thereby, to modify the Indenture or any supplemental
      indenture or the rights of the holders of Securities of such series to be
      affected, provided that no such modification will (i) extend the fixed maturity
      of any Securities, reduce the rate or extend the time of payment of interest
      thereon, reduce the principal amount thereof or the premium, if any, thereon,
      reduce the amount of the principal of Original Issue Discount Securities payable
      on any date, change the currency in which Securities are payable, or impair
      the
      right to institute suit for the enforcement of any such payment on or after
      the
      maturity thereof, without the consent of the holder of each Security so
      affected, or (ii) reduce the aforesaid percentage of Securities of any series
      the consent of the holders of which is required for any such modification
      without the consent of the holders of all Securities of such series then
      outstanding, or (iii) modify, without the written consent of the Trustee, the
      rights, duties or immunities of the Trustee.

    


    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
      times, place and rate, and in the coin or currency, herein
      prescribed.

    


    This
      Note
      is a Global Security registered in the name of a nominee of the Depository.
      This
      Note is exchangeable for Notes registered in the name of a person other than
      the
      Depository or its nominee only in the limited circumstances hereinafter
      described. Unless and until it is exchanged in whole or in part for definitive
      Notes in certificated form, this Note may not be

     

    
      
         

      

      
        -
          5 -

        
          

        

      

      
         

      

    


    transferred
      except as a whole by the Depository to a nominee of the Depository or by a
      nominee of the Depository to the Depository or another nominee of the
      Depository.

    


    The
      Notes
      represented by this Global Security are exchangeable for definitive Notes in
      certificated form of like tenor as such Notes in denominations of $1,000 and
      whole multiples of $1,000 in excess thereof only if (i) the Depository
      notifies the Company that it is unwilling or unable to continue as Depository
      for the Notes or (ii) the Depository ceases to be a clearing agency registered
      under the Securities Exchange Act of 1934, as amended, or (iii) the Company
      in
      its sole discretion decides to allow the Notes to be exchanged for definitive
      Notes in registered form. Any Notes that are exchangeable pursuant to the
      preceding sentence are exchangeable for certificated Notes issuable in
      authorized denominations and registered in such names as the Depository shall
      direct. As provided in the Indenture and subject to certain limitations therein
      set forth, the transfer of definitive Notes in certificated form is registrable
      in the register maintained by the Company in The City of New York for such
      purpose, upon surrender of the definitive Note for registration of transfer
      at
      the office or agency of the registrar, duly endorsed by, or accompanied by
      a
      written instrument of transfer in form satisfactory to the Company and the
      registrar duly executed by, the holder thereof or his attorney duly authorized
      in writing, and thereupon one or more new Notes of this series and of like
      tenor, of authorized denominations and for the same aggregate principal amount,
      will be issued to the designated transferee or transferees. Subject to the
      foregoing, this Note is not exchangeable, except for a Global Security or Global
      Securities of this issue of the same principal amount to be registered in the
      name of the Depository or its nominee.

    


    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.

    


    Prior
      to
      due presentment of this Note 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 Note is registered as the owner hereof for all purposes, whether
      or not this Note be overdue, and neither the Company, the Trustee nor any such
      agent shall be affected by notice to the contrary.

    


    The
      Company will pay additional amounts ("Additional Amounts") to the beneficial
      owner of any Note that is a non-United States person in order to ensure that
      every net payment on such Note will not be less, due to payment of U.S.
      withholding tax, than the amount then due and payable. For this purpose, a
      "net
      payment" on a Note means a payment by the Company or a paying agent, including
      payment of principal and interest, after deduction for any present or future
      tax, assessment or other governmental charge of the United States. These
      Additional Amounts will constitute additional interest on the Note.

    


    The
      Company will not be required to pay Additional Amounts, however, in any of
      the
      circumstances described in items (1) through (13) below.

                an extension of credit in the ordinary course of its trade or
                business.

                such Additional Amounts cannot be avoided by the use of reasonable
                measures available to it, other than substituting the obligor under
                the
                Notes or taking any action that would entail a material cost to the

                act is taken by a taxing authority of the United States on or after

                the
                Company or any affiliate, that results in a substantial probability
                that
                the Company will or may be required to pay Additional Amounts as
                described

                that an
                act taken by a taxing authority of the United States results in a
                substantial probability that the Company will or may be required
                to pay
                the Additional Amounts described under above, and delivers to the
                Trustee
                a certificate, signed by a duly authorized officer, stating that
                based on
