    CITIGROUP
      INC., a Delaware corporation (the "Company", which term includes any successor
      Person under the Indenture), for value received, hereby promises to pay to
      CDS
& Co., or registered assigns, the principal sum of C$_____________ on May
      24, 2027, and until the principal hereof is paid or made available for payment
      to pay interest thereon (i) from and including May 24, 2007 or from the most
      recent Interest Payment Date (as defined herein) to which interest has been
      paid
      or duly provided for, to but excluding May 24, 2022 (the “Fixed Rate Period”),
      semi-annually in equal installments on the twenty-fourth day of May and November
      of each year, commencing November 24, 2007, at a fixed rate of 5.160% per annum,
      and (ii) from and including May 24, 2022 or from and including the most recent
      Interest Payment Date thereafter to which interest has been paid or duly
      provided for to but excluding May 24, 2027 or an earlier date of redemption
      (the
“Floating Rate Period”), monthly, on the twenty-fourth day of each month,
      beginning June 24, 2022 (each such semi-annual or monthly payment date, an
      “Interest Payment Date”), at a rate per annum for each interest period equal to
      one-month CDOR (as defined herein) plus 0.80%, as determined by Citibank, N.A.,
      London office, as calculation agent (the “Calculation Agent”), and reset monthly
      as described herein. An interest period during the Floating Rate Period will
      be
      the period commencing on an Interest Payment Date and ending on the day
      preceding the next following Interest Payment Date. The interest so payable,
      and
      punctually paid or duly provided for, on any Interest Payment Date will, as
      provided in the Indenture, be paid pursuant to the instructions of the Person
      in
      whose name this Subordinated Note is registered at the close of business on
      the
      Record Date for such interest, which shall be (i) the May 9 and November 9
      (whether or not a Business Day) next preceding each Interest Payment Date during
      the Fixed Rate Period and (ii) the fifteenth day immediately preceding each
      Interest Payment Date during the Floating Rate Period.

    

    
      
         

      

      
         

        
          

        

      

      
         

      

       

    

    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 pursuant to
      the
      instructions of the Person in whose name this Subordinated 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 Subordinated 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 Subordinated 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.

    

    During
      the Fixed Rate Period, interest will be payable semi-annually in equal
      installments and, in the case of any period other than a full semi-annual
      period, interest hereon during the Fixed Rate Period will be calculated on
      the
      basis of the actual number of days elapsed and a year of 365 days or (in the
      case of a leap year) 366 days. Interest hereon during the Floating Rate Period
      will be calculated on the basis of the actual number of days elapsed and a
      year
      of 365 days or (in the case of a leap year) 366 days. All Canadian dollar
      amounts resulting from the calculations described in the preceding two sentences
      will be rounded to the nearest cent.

    

    During
      the Fixed Rate Period, if either an Interest Payment Date or a redemption date
      falls on a day that is not a Toronto Business Day, the payment due on such
      date
      will be postponed to the next succeeding Toronto Business Day, and no further
      interest will accrue in respect of such postponement. "Toronto Business Day"
      means any Toronto business day on which commercial banks and foreign exchange
      markets settle payments and are open for general business (including dealings
      in
      foreign currency deposits and foreign exchange) in Toronto. 

    

    During
      the Floating Rate Period, if an Interest Payment Date falls on a day that is
      not
      a Toronto Business Day, such Interest Payment Date will be the next succeeding
      Toronto Business Day, unless that day falls in the next calendar month, in
      which
      case the Interest Payment Date will be the first preceding Toronto Business
      Day.
      If either the maturity date or a redemption date falls on a day that is not
      a
      Toronto Business Day, the payment due on such date will be postponed to the
      next
      succeeding Toronto Business Day, and no further interest will accrue in respect
      of such postponement.

    

    
      
         

      

      
         

        
          

        

      

      
         

      

       

    

    During
      both the Fixed Rate Period and the Floating Rate Period, if a date for payment
      of interest or principal on the Subordinated Note 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 such
      payment was due. No interest will accrue on any amounts payable for the period
      from and after the due date for payment of such interest or
      principal.

    

    The
      Subordinated Notes will be represented by beneficial interests in fully
      registered permanent global notes (the "Global Notes") without interest coupons
      attached, which will be registered in the name of CDS & Co., as nominee for
      CDS, and deposited with CDS.

    

    Beneficial
      interests in the Global Notes will be represented through book-entry accounts
      of
      financial institutions acting on behalf of beneficial owners as direct and
      indirect participants in CDS. Clearstream International (“Clearstream”) and the
      Euroclear System (“Euroclear”) will hold interests on behalf of their
      participants through customers' securities accounts in their respective names
      on
      the books of their respective Canadian subcustodians, each of which is a
      Canadian Schedule I chartered bank ("Canadian subcustodians"), which in turn
      will hold such interests in customers' securities accounts in the names of
      the
      Canadian subcustodians on the books of CDS.

    

    All
      payments of principal and interest on the Subordinated Notes will be made in
      Canadian dollars. Payments on the Global Notes will be made on behalf of the
      Company by the fiscal agent pursuant to the instructions of the Person in whose
      name this Subordinated Note is registered at the close of business on the
      relevant Record Date. All payments made by the fiscal agent on the Company’s
      behalf shall discharge the liability of the Company under the Subordinated
      Notes
      to the extent of the sums so paid.

    

    Reference
      is hereby made to the further provisions of this Subordinated 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
      the Fiscal Agent on behalf of the Trustee by manual signature, this Subordinated
      Note shall not be entitled to any benefit 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.

    This
      Subordinated Note is one of a duly authorized issue of Securities of the Company
      (the "Subordinated Notes"), issued and to be issued in one or more series under
      the Indenture, dated as of April 12, 2001, as supplemented August 2, 2004 (the
      "Indenture"), between the Company and The Bank of New York (successor to J.P.
      Morgan Trust Company, N.A. and Bank One Trust Company, N.A.), 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
      Subordinated Notes and of the terms upon which the Subordinated Notes are,
      and
      are to be, authenticated and delivered. This Subordinated Note is one of the
      series designated on the face hereof, initially issued in the aggregate
      principal amount of C$500,000,000.

    

    The
      Company covenants and agrees that the indebtedness evidenced by the Subordinated
      Notes is subordinate and junior in right of payment to all Senior Indebtedness
      (as defined in the Indenture) to the extent provided in the Indenture, and
      each
      holder of Subordinated Notes, by his or her acceptance thereof, likewise
      covenants and agrees to the subordination provided in the Indenture (including
      Article Fourteen thereof) and shall be bound by the provisions
      thereof.

    

    In
      the
      event that the Company shall default in the payment of any principal of (or
      premium, if any) or interest on any Senior Indebtedness when the same becomes
      due and payable after any applicable grace period, whether at maturity or at
      a
      date fixed for prepayment or by declaration or otherwise, then, unless and
      until
      such default shall have been cured or waived or shall have ceased to exist,
      no
      direct or indirect payment (in cash, property, securities, by set-off or
      otherwise) shall be made or agreed to be made on account of the principal of,
      or
      premium, if any, or interest on the indebtedness evidenced by the Subordinated
      Notes, or in respect of any redemption, retirement or other acquisition of
      any
      of the Subordinated Notes, except that holders of Subordinated Notes may receive
      and retain (x) securities of the Company or any other corporation provided
      for
      by a plan of reorganization or readjustment the payment of which is subordinate,
      at least to the extent provided in these subordination provisions with respect
      to the indebtedness evidenced by the Subordinated Notes, to the payment of
      all
      Senior Indebtedness at the time outstanding and to any securities issued in
      respect thereof under any such plan of reorganization or readjustment and (y)
      payments made from a defeasance trust created pursuant to Article Eleven of
      the
      Indenture.

    

    In
      the
      event of:

    

    (i)
      any
      insolvency, bankruptcy, receivership, liquidation, reorganization, readjustment,
      composition or other similar proceeding relating to the Company, its creditors
      or its property, 

    

    (ii)
      any
      proceeding for liquidation, dissolution or other winding up of the Company,
      voluntary or involuntary, whether or not involving insolvency or bankruptcy
      proceedings,

    

    
      
         

      

      
         

        
          

        

      

      
         

      

       

    

    (iii)
      any
      assignment by the Company for the benefit of creditors, or

    

    (iv)
      any
      other marshalling of the assets of the Company,

    

    all
      Senior Indebtedness (including any interest thereon accruing after the
      commencement of any such proceedings) shall first be paid in full before any
      payment or distribution, whether in cash, securities or other property, shall
      be
      made to any Holder of any of the Subordinated Notes on account thereof (except
      as provided in the next sentence). Any payment or distribution, whether in
      cash,
      securities or other property (other than (x) securities of the Company or any
      other corporation provided for by a plan of reorganization or readjustment
      the
      payment of which is subordinate, at least to the extent provided in these
      subordination provisions with respect to the indebtedness evidenced by the
      Subordinated Notes, to the payment of all Senior Indebtedness at the time
      outstanding and to any securities issued in respect thereof under any such
      plan
      of reorganization or readjustment and (y) payments made from a defeasance trust
      created pursuant to Article Eleven of the Indenture), which would otherwise
      (but
      for these subordination provisions) be payable or deliverable in respect of
      the
      Subordinated Notes shall be paid or delivered directly to the holders of Senior
      Indebtedness in accordance with the priorities then existing among such holders
      until all Senior Indebtedness (including any interest thereon accruing after
      the
      commencement of any such proceedings) shall have been paid in full.

    

    This
      Subordinated Note will bear interest for each interest period during the
      Floating Rate Period at a rate determined by Citibank, N.A., London office,
      acting as Calculation Agent. The interest rate on this Subordinated Note for
      a
      particular interest period will be a per annum rate equal to the Canadian dollar
      one-month Banker’s Acceptance Rate (“CDOR”) as determined on the related
      interest determination date plus 0.80%. The interest determination date for
      an
      interest period will be the first day of such interest period. Promptly upon
      determination, the Calculation Agent will inform the Trustee and the Company
      of
      the interest rate for the next interest period. Absent manifest error, the
      determination of the interest rate by the Calculation Agent shall be binding
      and
      conclusive on the holders of Subordinated Notes, the Trustee and the
      Company.

    

    On
      any
      interest determination date, CDOR will be equal to the offered rate for Canadian
      dollar bankers’ acceptances having a maturity of one month, as such rate appears
      on the Reuters Screen CDOR page at approximately 10:00 a.m., Toronto time,
      on
      such interest determination date. If the Reuters Screen CDOR page is replaced
      by
      another service or ceases to exist, the calculation agent will use the replacing
      service or such other service that may be nominated by the person sponsoring
      such information appearing there for the purpose of displaying offered rates
      for
      Canadian dollar bankers' acceptances having a maturity of one month. If no
      such
      service exists, the Calculation Agent shall proceed as described in the next
      paragraph.

    

    If
      no
      offered rate appears on the Reuters Screen CDOR page on an interest
      determination date at approximately 10:00 a.m., Toronto time, then CDOR will
      be
      the average of the bid rates of interest for Canadian dollar bankers'
      acceptances with maturities of one month for same day settlement as quoted
      by
      such of the Schedule I banks (as defined in the Bank Act (Canada)) as may quote
      such a rate as of 10:00 a.m., Toronto time, on such interest determination
      date.
      If at least two quotations are provided, CDOR will be the arithmetic average
      of
      the quotations provided. Otherwise, the rate of CDOR for the next interest
      period will be set equal to the rate of CDOR for the preceding interest
      period.

    

    
      
         

      

      
         

        
          

        

      

      
         

      

       

    

    If
      an
      event of default (as defined in the Indenture) with respect to Subordinated
      Notes of this series shall occur and be continuing, the principal of the
      Subordinated 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 Subordinated Note upon compliance by the Company with
      certain conditions set forth in Article Eleven thereof, which provisions apply
      to this Subordinated Note.

    

    The
      Indenture contains provisions permitting the Company and the Trustee, without
      the consent of the holders of 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
      a
      majority of the 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 shall, without the consent of the holder of each
      Outstanding Security so affected, (x) change the Stated Maturity of the
      principal of, or any installment of principal of or interest on, any Security,
      or reduce the principal amount thereof or the rate of interest thereon or any
      premium thereon, or change any place of payment where, or the coin or currency
      in which any Security or any premium or interest thereon is payable, or impair
      the right to 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 modify the provisions of the Indenture with respect to
      the
      subordination of the Securities in a manner adverse to the Securityholders
      or
      (y) reduce the aforesaid percentage in principal amount of the Outstanding
      Securities of any series, the consent of the holders of which is required for

      any
      waiver provided for in the Indenture, or (z) modify certain other provisions
      of
      the Indenture, as set forth in Section 13.02 of the Indenture.

    

    No
      reference herein to the Indenture and no provision of this Subordinated 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
      Subordinated Note at the times, place and rate, and in the coin or currency,
      herein prescribed.

    

    This
      Subordinated Note is a Global Security registered in the name of a nominee
      of
      the Depository. This Subordinated Note is exchangeable for Subordinated 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 Subordinated Notes in certificated
      form, this Subordinated Note may not be 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.

    

    
      
         

      

      
         

        
          

        

      

      
         

      

       

    

    If
      CDS
      notifies the Company that it is unwilling or unable to continue as depositary
      in
      connection with the Global Notes or ceases to be a recognized clearing agency
      under the Securities Act (Ontario) or other applicable Canadian securities
      legislation, and a successor depositary is not appointed by the Company within
      90 days after receiving such notice or becoming aware that CDS is no longer
      so
      recognized, or if both Clearstream and Euroclear notify the Company that they
      are unwilling or unable to continue as a clearing system in connection with
      the
      Subordinated Notes, or if the Company in its sole discretion decides to allow
      some or all of the Subordinated Notes to be exchangeable for definitive
      securities in registered form, then the beneficial owners of Subordinated Notes
      affected by such events will be notified through the relevant chain of
      intermediaries that definitive notes are available. Beneficial owners of
      affected book-entry notes will then be entitled (1) to receive physical delivery
      in certificated form of definitive notes equal in principal amount to their
      beneficial interest and (2) to have the definitive notes registered in their
      names. The definitive notes will be issued in denominations of C$100,000 and
      integral multiples of C$1,000 in excess thereof. Definitive notes will be
      registered in the name or names of the person or persons CDS, Euroclear and
      Clearstream specify in a written instruction to the registrar. CDS or Euroclear
      and Clearstream may base their written instruction upon directions they receive
      from their participants. Thereafter, the holders of the definitive notes will
      be
      recognized as the "holders" of the notes under the Indenture.

    

    In
      the
      event definitive notes are issued, the holders of definitive notes will be
      able
      to receive payments of principal and interest on their notes at the office
      of
      the Company's paying agents maintained in Toronto and in London. Payment of
      principal of a definitive note may be made only against surrender of the note
      to
      one of the Company's paying agents. The Company also has the option of mailing
      checks to the registered holders of the notes.

    

    In
      the
      event definitive notes are issued, the holders of definitive notes will be
      able
      to transfer their notes, in whole or in part, by surrendering the notes for
      registration of transfer at the office of Citibank Canada, Toronto office,
      or
      Citibank, N.A., London office, duly endorsed by or accompanied by a written
      instrument of transfer in form satisfactory to the Company and the registrar.
      Upon surrender, the Company will execute, and the authenticating agent will
      authenticate and deliver, new notes to the designated transferee in the amount
      being transferred, and a new note for any amount not being transferred will
      be
      issued to the transferor. Such new notes will be delivered free of charge at
      the
      offices of Citibank, N.A. in London or Citibank Canada in Toronto, as requested
      by the owner of such new notes. The Company will not charge any fee for the
      registration of transfer or exchange, except that it may require the payment
      of
      a sum sufficient to cover any applicable tax or other governmental charge
      payable in connection with the transfer.

    

    Prior
      to
      due presentment of this Subordinated Note for registration of transfer, the
      Company, the Fiscal Agent and any agent of the Company or the Fiscal Agent
      may
      treat the Person in whose name this Subordinated Note is registered as the
      owner
      hereof for all purposes, whether or not this Subordinated Note be overdue,
      and
      neither the Company, the Fiscal Agent 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 Subordinated Note that is a non-United States person in order
      to
      ensure that every net payment on such Subordinated 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 Subordinated 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 Subordinated Note.

      Company will not be required to pay Additional Amounts, however, in any of

      circumstances described in items (1) through (13) below.

                imposed or withheld solely by reason of the beneficial
                owner:

                as a result of any tax, assessment or other governmental charge that
                is
                imposed or withheld solely by reason of the beneficial
                owner:

                obligation to pay Additional Amounts will only apply to the extent
                that a
                beneficiary or settlor in relation to the fiduciary, or a beneficial
                owner
                or member of the partnership, limited liability company or other
                fiscally
                transparent entity, would not have been entitled to the payment of
                an
                Additional Amount had the beneficiary, settlor, beneficial owner
                or member
                received directly its beneficial or distributive share of the
                payment.

                owner or any other person to comply with applicable certification,
                identification, documentation or other information reporting requirements.
                This exception to the obligation to pay Additional Amounts will only
                apply
                if compliance with such reporting requirements is required by statute
                or
                regulation of the United States or by an applicable income tax treaty
                to

                from
                such tax, assessment or other governmental
                charge.

                reduced
                as a result of any tax, assessment or other governmental charge that
                is
                collected or imposed by any method other than by withholding from
                a
                payment on a Subordinated Note by the Company or a paying
                agent.

                more than
                15 days after the payment becomes due or is duly provided for, whichever

                is
                imposed or withheld by reason of the presentation by the beneficial
                owner
                of a Subordinated Note for payment more than 30 days after the date
                on which such payment becomes due or is duly provided for, whichever

      redemption date, the Subordinated Notes will cease to accrue interest on and

              (a)

            	
              the
                Company becomes or will become obligated to pay Additional Amounts
                as
                described above;

            

    

    
      	 	 	
              (b)

            	
              the
                obligation to pay Additional Amounts arises as a result of any change
                in
                the laws, regulations or rulings of the United States, or an official
                position regarding the application or interpretation of such laws,
                regulations or rulings, which change is announced or becomes effective
                on
                or after May 10, 2007; and

            

    

    
      	 	 	
              (c)

            	
              the
                Company determines, in its business judgment, that the obligation
                to pay
                such Additional Amounts cannot be avoided by the use of reasonable
                measures available to it, other than substituting the obligor under
                the
                Subordinated Notes or taking any action that would entail a material
                cost
                to the Company.

            

    

    

    
      	 	
              (2)

            	
              The
                Company may also redeem the Subordinated Notes, at its option,
                if:

            

    

    
      	 	 	
              (a)

            	
              any
                act is taken by a taxing authority of the United States on or after
                May
                10, 2007, whether or not such act is taken in relation to the Company
                or
                any subsidiary, that results in a substantial probability that the
                Company
                will or may be required to pay Additional Amounts as described
                above;

            

    

    
      	 	 	
              (b)

            	
              the
                Company determines, in its business judgment, that the obligation
                to pay
                such Additional Amounts cannot be avoided by the use of reasonable
                measures available to it, other than substituting the obligor under
                the
                Subordinated Notes or taking any action that would entail a material
                cost
                to the Company; and

            

    

     

    
      
         

      

      
         

        
          

        

      

      
         

      

       

    

    
      	 	 	
              (c)

            	
              the
                Company receives an opinion of independent counsel to the effect
                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 above, and delivers to the Trustee
                a
                certificate, signed by a duly authorized officer, stating that based
                on
                such opinion the Company is entitled to redeem the Subordinated Notes
                pursuant to their terms.

            

    

    

    Any
      redemption of the Subordinated Notes as set forth in clauses (1) or (2) above
      shall be in whole, and not in part, and will be made at a redemption price
      equal
      to 100% of the principal amount of the Subordinated Notes Outstanding (as
      defined in the Indenture) plus accrued interest thereon to the date of
      redemption. Holders shall be given not less than 30 days nor more than 60 days’
prior notice by the Trustee of the date fixed for such redemption.

    

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

      funds, to such account at the Fiscal Agent in London or Canada as the Fiscal
      Agent may from time to time specify (the “Redemption
      Account”)
      on the
      Business Day such payment is due as set forth in the Notes and
      Conditions.

    

    The
      Issuer hereby authorizes and directs the Fiscal Agent, from the amounts so
      paid
      to it, to make payment of the principal of, and interest on, the Notes on the
      due date for payment set forth in the Conditions and this Agreement. If
      applicable, the Fiscal Agent will, from funds so received from the Issuer,
      credit to the account of the Paying Agent the amounts of all such payments
      made
      by it in accordance with the provisions of this Agreement.

    

    The
      Issuer shall confirm to the Fiscal Agent not later than 10:00 a.m. (London
      time)
      on the second Business Day before the relevant date for such payment that it
      has
      issued irrevocable payment instructions for such payment to be made.

    

    The
      Fiscal Agent, in coordination with CDS, shall procure tax forms required for
      exemption from withholding tax under the U.S. Internal Revenue Code.

    

    4.2 If
      for
      any reason the Fiscal Agent does not receive unconditionally the full amount
      payable by the Issuer on the relevant due date in respect of all the outstanding
      or maturing Notes, the Fiscal Agent shall forthwith notify immediately the
      Issuer by telephone followed by facsimile and the Fiscal Agent shall not be
      bound to make any payment of principal or interest in respect of the Notes
      until
      the Fiscal Agent has received to its order the full amount of the monies then
      due and payable in respect of all outstanding or maturing Notes, provided,
      however, that if the Fiscal Agent shall, in its discretion, make any payment
      of
      principal or interest on or after the due date therefor in respect of the Notes
      prior to its unconditional receipt of the full amount then due and payable
      in
      respect of all outstanding Notes, the Issuer will promptly pay such amount
      to
      the Fiscal Agent and will compensate the Fiscal Agent at a rate equal to the
      Fiscal Agent’s cost of funding.

    

    4.3 Out
      of
      the sums paid to the Fiscal Agent in respect of interest and principal on the
      Notes, the Fiscal Agent will make payment free of charge in accordance with
      instructions from the registered holder of the Global Note as stipulated in
      Clause 9 below, in the amounts specified in the Conditions. The Fiscal Agent
      shall obtain from the Registrar, and the Registrar shall supply, such details
      as
      are required for the Paying Agent to make payment as stated above.

    

    
      
        4.4
          In
          respect of the monies paid to it relating to any Note, the Fiscal
          Agent

      

    

    

    4.4.1
      shall not be entitled to exercise any lien, right of set-off or similar claim
      (including without limitation any claim arising from or relating to any other
      issue of securities by the Issuer), 

    
      
        4.4.2
          shall
          not
          be required to account for interest thereon and

      

    

    
      
        4.4.3
          money
          held by it need not be segregated except as may be required by applicable

    5.1 On
      behalf
      and at the request and expense of the Issuer, the Fiscal Agent shall cause
      to be
      published any notices required to be given by the Issuer in accordance with

      Issuer shall provide to the Fiscal Agent sufficient copies of all documents
      required by the Conditions to be available for issue or inspection, and the
      Fiscal Agent shall make such copies available to Noteholders upon their
      request.

    6.1 Subject
      to the terms of the Indenture, promptly upon the Issuer’s request, the Registrar
      shall take all measures necessary to cancel any Notes which the Issuer has
      repurchased or whose maturity has been accelerated pursuant to the Conditions.
      The Registrar shall cause any such Notes to be cancelled in accordance with
      the
      procedures established for that purpose by CDS, resulting in a reduction in
      the
      aggregate amount of the Notes represented by the Global Note by the aggregate
      amount of the Notes so cancelled.

    

    6.2 On
      the
      same day such cancellation is effected, the Registrar shall record such
      cancellation of Notes on the Register in such a way that the aggregate principal
      amount of Notes cancelled at any time together with the aggregate principal
      amount of Notes outstanding and represented by the Global Notes shall equal
      the
      aggregate principal amount of Notes originally issued by the
      Issuer.

    

    6.3 The
      Registrar shall upon request furnish the Issuer with a notice of cancellation
      signed by an authorized officer of the Registrar confirming the cancellation
      of
      such Notes and the corresponding reduction of the relevant Global
      Note(s).

      Conditions. The Register shall show the aggregate amount of Notes represented
      by
      the Global Note at the date of issue and all subsequent transfers and exchanges

    7.3 The
      Registrar shall at all reasonable times during office hours make the Register
      available to the Issuer and the Fiscal Agent or any person authorised by either
      of them for inspection and for the taking of copies thereof or extracts
      therefrom, and the Registrar shall deliver to such persons such information

              CONDITIONS
                OF APPOINTMENT

            

    

    

    10.1 The
      Issuer will pay to the Agents a remuneration for all services rendered hereunder
      by the Agents in connection with the Notes together with any expenses incurred
      as separately agreed upon by the Agents and the Issuer.

    

    10.2
      The
      Issuer will indemnify and hold harmless each of the Agents against any loss,
      liability or expense which it may incur or any claim, action or demand which
      may
      be made against it resulting from the negligence or wilful misconduct on the
      part of the Issuer (or its officers, employees or agents (other than the Agents
      and their officers, employees, and agents)) and arising out of or in connection
      with such Agent’s appointment or the exercise of its powers and duties hereunder
      without negligence or wilful misconduct on the part of such Agent.

    

    10.3
      Each
      Agent will indemnify and hold harmless the Issuer against any loss, liability
      or
      expense incurred by the Issuer or any claim, action or demand which may be
      made
      against the Issuer resulting from the negligence or wilful misconduct on the
      part of such Agent (or such Agent’s officers, employees or agents) and arising
      out of or in connection with such Agent’s duties hereunder. Notwithstanding the
      foregoing, under no circumstances will any Agent be liable to the Issuer or
      any
      other person for any consequential loss (being loss of business, goodwill,
      opportunity or profit) even if advised to the possibility of such loss or
      damages.

    

    10.4
      The
      indemnities above shall survive the termination or expiry of this
      Agreement.

    

    10.5
      Each
      of the Agents shall be protected and shall incur no liability for or in respect
      of any action taken, omitted or suffered in reliance upon any instruction or
      communication from the Issuer or any document reasonably believed by it to
      be
      genuine and to have been delivered, signed or sent by the proper party or
      parties in accordance with the provisions hereof, except such as may result
      from
      its own negligence or wilful misconduct or that of its officers, employees
      or
      agents.

    

    10.6 
      In
      acting hereunder and in connection with the Notes, the Agents do not assume
      any
      relationship of agency and trust for the Noteholders, and shall not have any
      obligation towards them except that all funds held by the Fiscal Agent for
      payment of principal of or interest on the Notes shall be held exclusively
      for
      the benefit of and for payment to the Noteholders and shall be applied as set
      forth herein and in the Conditions. Except as otherwise required by applicable
      law, no Agent will be required to segregate any funds held by it hereunder
      from
      any of its other funds.

    

    10.7 
      Nothing
      herein shall be deemed to require any Agent to advance its own funds in the
      performance of its duties hereunder.

    

    10.8 The
      Agents may consult with legal and other professional advisers selected in good
      faith and satisfactory to them and the opinion of such advisers shall be full
      and complete protection in respect of any action taken, omitted or suffered
      hereunder in good faith and without negligence and in accordance with the
      opinion of such advisers.

    

    10.9
      The
      Agents shall be obliged to perform such duties and only such duties as are
      herein 

    specifically
      set forth, and no implied duties or obligations shall be read into this
      Agreement against the Agents. No Agent shall be under any obligation to take
      any
      action hereunder which it expects will result in any expense or liability of
      such Agent, the payment of which within a reasonable time is not, in its
      opinion, assured to it. The obligations of the Agents hereunder are several
      and
      not joint.

    

    10.10 The
      Agents, their affiliates and their respective officers and employees, in their
      individual or any other capacity, may become the owner of, or acquire any
      interest in, any Notes with the same rights that the Agents would have it they
      were not the Agents hereunder.

      its
      capacity as such may be removed at any time by the giving to it of at least
      30
      days’ written notice to that effect signed on behalf of the Issuer specifying
      the date on which such removal shall become effective. Each of the Fiscal Agent,

      by giving at least 30 days’ written notice (unless the Issuer agrees to accept
      less notice) to that effect to the Issuer specifying the date on which such
      resignation shall become effective. Notwithstanding the foregoing, no such
      resignation or removal shall take effect within 30 days before or after any
      due
      date for payment of any Notes or before a new Fiscal Agent, Registrar,
      Calculation Agent and Principal Paying Agent, as the case may be, shall have
      been appointed by the Issuer as hereinafter provided, and such new Agent shall
      have accepted such appointment. Any change in any Agent shall be notified by
      the
      Issuer to the other Agent(s).

    

    12.2 The
      Issuer agrees with the Fiscal Agent that if, by the day falling 10 days before
      the expiry of any notice under Clause 12.1 above, the Issuer has not appointed
      a
      replacement Fiscal Agent, then the Fiscal Agent shall be entitled, on behalf
      of
      the Issuer, to appoint in its place any reputable financial institution of
      good
      standing and the Issuer shall not unreasonably object to such
      appointment.

    

    12.3 Upon
      the

      Clause 12.1, the Fiscal Agent, Registrar and Principal Paying Agent so removed
      shall cease to be a Fiscal Agent, Registrar, Calculation Agent and Principal
      Paying Agent, as the case may be, hereunder. Prior to the effectiveness of

      Agent shall hold all moneys deposited with it or held by it hereunder in respect
      of the Notes to the order of the respective successor Fiscal Agent, Registrar
      and Principal Paying Agent.
