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 A$0 on August 7, 2019 and to pay interest thereon from and including August 7, 2015 or from the most
recent Interest Payment Date to which interest has been paid or duly provided for, quarterly, on the seventh day of each February, May, August, and November, commencing November 7, 2015, at the rate per annum for each Interest Period of
three-month BBSW, determined as provided herein, plus 1.2500% 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 Business Day (as defined below) 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 the actual number of days elapsed in an Interest Period and a 365-day year (fixed).
Australian dollar amounts resulting from such calculation will be rounded to the nearest cent, with one-half cent being rounded upward. An “Interest Period” shall be the period from and including an Interest Payment Date (or from
November 7, 2015 in the case of the first Interest Payment Date) to and including the day immediately preceding the next Interest Payment Date. 

If an Interest Payment Date falls on a day that is not a Business Day, such Interest Payment Date will be the next succeeding Business Day,
unless that day falls in the next calendar month, in which case the Interest Payment Date will be the first preceding Business Day. If the Maturity of the Notes falls on a day that is not a Business Day, the payment due on Maturity will be postponed
to the next succeeding Business Day, and no further interest will accrue in respect of such postponement. 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 each of The City of New York, Sydney and London. 
 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 London in Australian dollars, including holders of interests in this Note through The Depository Trust Company unless they make an election to receive payment in United
States dollars in accordance with the procedures of The Depository Trust Company and the Fiscal Agency Agreement dated as of August 7, 2015 (the “Fiscal Agency Agreement”), in which case the exchange agent under the Fiscal Agency
Agreement will convert the Australian dollars paid by the Company into United States dollars in accordance with the Fiscal Agency Agreement. 

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

 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 November 13, 2013 (as amended and supplemented to date, the “Indenture”), between the Company and The Bank of New York Mellon, 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 A$600,000,000. 
 This Note will bear interest for each Interest Period at a rate determined by Citibank, N.A.,
acting as Calculation Agent. The interest rate on this Note for a particular Interest Period will be a per annum rate equal to three-month BBSW as determined on the related Interest Determination Date, plus 1.2500%. The Interest Determination Date
for an Interest Period will be the first day of such Interest Period. The Interest Determination Date for the first Interest Period is August 7, 2015. 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 Notes, the Trustee and the Company. 

On any Interest Determination Date, BBSW will be equal to the offered rate for prime bank eligible securities having a tenor closest to the
interest period which is designated as the “AVG MID” on the Reuters Screen BBSW Page at approximately 10:10 a.m., Sydney time, on such Interest Determination Date. 

If the rate is not published prior to 10:30 a.m., Sydney time, on the Interest Determination Date, or if it is displayed but the Calculation
Agent determines that there is a manifest error in that rate, then the BBSW Rate will be the rate determined by the Calculation Agent having regard to comparable indices then available. 

“Reuters Screen BBSW page” means the display which appears on the display on Reuters (or any successor service) as page
“BBSW” (or any other page as may replace such page), for the purpose of displaying BBSW rates or base lending rates of major Australian banks. 

So long as the Notes of this series are in the form of Global Securities only, all Notes of this series will collectively be evidenced
(a) by this Global Note (the “DTC Global Note”) and (b) by the Global Security of this series registered in the name of Citivic Nominees Limited (the “International Global Note”). The DTC Global Note and the
International Global Note will at all times collectively represent the aggregate principal amount of this series outstanding from time to time. If at any time a portion of the International Global Note is exchanged for an interest in the DTC Global
Note, the principal amount of the DTC Global Note shall be increased by the amount of such portion, and the DTC Global Note shall be endorsed on the Schedule of Exchanges of Interests thereto to reflect such principal increase, subject to the
limitation that in no event may the principal amount of the DTC Global Note be greater than the equivalent in U.S. 

  
 R-1 








 
dollars of A$600,000,000. If at any time a portion of the DTC Global Note is exchanged for an interest in the International Global Note, the principal amount of the DTC Global Note shall be
decreased by the amount of such portion, and the DTC Global Note shall be endorsed on the Schedule of Exchanges of Interests thereto to reflect such principal decrease. To ascertain the U.S. dollar equivalent of the principal amount endorsed on the
Schedule of Exchanges of Interests attached to the DTC Global Note, inquiry shall be made of the exchange agent under the Fiscal Agency Agreement, and the U.S. dollar equivalent quoted by such exchange agent (and the date of such quote) shall be
noted on such Schedule of Exchanges of Interests next to the corresponding Australian dollar amount. 
 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 12.02 and 12.03 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 a majority 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 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. 

  
 R-2 








 The Notes represented by this Global Security are exchangeable for definitive Notes in
certificated form of like tenor as such Notes in denominations of A$1,000 and integral multiples of A$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 DTC
Global Note or (ii) the Depository ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, or (iii) both the Euroclear System and Clearstream Banking, société anonyme, notify the
Company that they are unwilling or unable to continue as a clearing system for the International Global Note or (iv) 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 (14) below. 

  
 R-3 









	 	(1)	Additional Amounts will not be payable if a payment on a Note is reduced as a result of any tax, assessment or other governmental charge that is imposed or withheld solely by reason of the beneficial owner:


  

	 	(a)	having a relationship with the United States as a citizen, resident or otherwise; 

  

	 	(b)	having had such a relationship in the past or 

  

	 	(c)	being considered as having had such a relationship. 

  

	 	(2)	Additional Amounts will not be payable if a payment on a Note is reduced as a result of any tax, assessment or other governmental charge that is imposed or withheld solely by reason of the beneficial owner:


  

	 	(a)	being treated as present in or engaged in a trade or business in the United States; 

  

	 	(b)	being treated as having been present in or engaged in a trade or business in the United States in the past or 

  

	 	(c)	having or having had a permanent establishment in the United States. 

  

	 	(3)	Additional Amounts will not be payable if a payment on a Note is reduced as a result of any tax, assessment or other governmental charge that is imposed or withheld in whole or in part by reason of the beneficial owner
being or having been any of the following (as such terms are defined in the Internal Revenue Code of 1986, as amended): 

  

	 	(a)	personal holding company; 

  

	 	(b)	foreign personal holding company; 

  

	 	(c)	foreign private foundation or other foreign tax-exempt organization; 

  

	 	(d)	passive foreign investment company; 

  

	 	(e)	controlled foreign corporation or 

  

	 	(f)	corporation which has accumulated earnings to avoid United States federal income tax. 

  

	 	(4)	Additional Amounts will not be payable if a payment on a Note is reduced as a result of any tax, assessment or other governmental charge that is imposed or withheld solely by reason of the beneficial owner owning or
having owned, actually or constructively, 10 percent or more of the total combined voting power of all classes of stock of the Company entitled to vote or by reason of the beneficial owner being a bank that has invested in a Note as an extension of
credit in the ordinary course of its trade or business. 

 For purposes of items (1) through (4) above, “beneficial owner”
means a fiduciary, settlor, beneficiary, member or shareholder of the holder if the holder is an estate, trust, partnership, limited liability company, corporation or other entity, or a person holding a power over an estate or trust administered by
a fiduciary holder. 

  
 R-4 









	 	(5)	Additional Amounts will not be payable to any beneficial owner of a Note that is a: 

  

	 	(a)	fiduciary; 

  

	 	(b)	partnership; 

  

	 	(c)	limited liability company or 

  

	 	(d)	other fiscally transparent entity 

 or that is not the sole beneficial owner of the Note, or any
portion of the Note. However, this exception to the 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. 

 

	 	(6)	Additional Amounts will not be payable if a payment on a Note is reduced as a result of any tax, assessment or other governmental charge that is imposed or withheld solely by reason of the failure of the beneficial
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 which the United States is a party as a precondition to exemption from such tax, assessment or other governmental charge.


  

	 	(7)	Additional Amounts will not be payable if a payment on a Note is 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 Note by the Company or a paying agent. 

  

	 	(8)	Additional Amounts will not be payable if a payment on a Note is reduced as a result of any tax, assessment or other governmental charge that is imposed or withheld by reason of a change in law, regulation, or
administrative or judicial interpretation that becomes effective more than 15 days after the payment becomes due or is duly provided for, whichever occurs later. 

  


	 	(9)	Additional Amounts will not be payable if a payment on a Note is reduced as a result of any tax, assessment or other governmental charge that is imposed or withheld by reason of the presentation by the beneficial owner
of a Note for payment more than 30 days after the date on which such payment becomes due or is duly provided for, whichever occurs later.

	 	(a)	estate tax; 

  

	 	(b)	inheritance tax; 

  

	 	(c)	gift tax; 

  

	 	(d)	sales tax; 

  

	 	(e)	excise tax; 

  

	 	(f)	transfer tax; 

  

	 	(g)	wealth tax; 

  

	 	(h)	personal property tax or 

  

	 	(i)	any similar tax, assessment, withholding, deduction or other governmental charge. 

  

	 	(11)	Additional Amounts will not be payable if a payment on a Note is reduced as a result of any tax, assessment, or other governmental charge required to be withheld by any paying agent from a payment of principal or
interest on a Note if such payment can be made without such withholding by any other paying agent. 

  

	 	(12)	Additional amounts will not be payable if a payment on a Note is reduced as a result of any tax, assessment or other governmental charge that is required to be made pursuant to any European Union directive on the
taxation of savings income or any law implementing or complying with, or introduced to conform to, any such directive. 

  

	 	(13)	Additional amounts will not be payable if a payment on a Note is reduced as a result of any withholding, deduction, tax, duty assessment or other governmental charge that would not have been imposed but for a failure by
the holder or beneficial owner of a Note (or any financial institution through which the holder or beneficial owner holds the Note or through which payment on the Note is made) to take any action (including entering into an agreement with the
Internal Revenue Service, or a governmental authority of another jurisdiction if the holder is entitled to the benefits of an intergovernmental agreement between that jurisdiction and the United States) or to comply with any applicable
certification, documentation, information or other reporting requirement or agreement concerning accounts maintained by the holder or beneficial owner (or any such financial institution), or concerning ownership of the holder or beneficial owner, or
any substantially similar requirement or agreement. 

  

	 	(14)	Additional Amounts will not be payable if a payment on a Note is reduced as a result of any combination of items (1) through (13) above. 


Except as specifically provided herein, the Company will not be required to make any payment of any tax, assessment or other governmental
charge imposed by any government or a political subdivision or taxing authority of such government. 

  
 R-6

	 	(a)	any individual who is a citizen or resident of the United States; 

  

	 	(b)	any corporation, partnership or other entity created or organized in or under the laws of the United States; 

  

	 	(c)	any estate if the income of such estate falls within the federal income tax jurisdiction of the United States regardless of the source of such income and 


 

	 	(d)	any trust if a United States court is able to exercise primary supervision over its administration and one or more United States persons have the authority to control all of the substantial decisions of the trust.


 Additionally, “non-United States person” means a person who is not a
United States person, and “United States” means the states of the United States of America and the District of Columbia, but excluding its territories and its possessions.

	 	(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 July 28, 2015 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
Notes or taking any action that would entail a material cost to the Company. 

  

	 	(2)	The Company may also redeem the Notes, at its option, if: 

  

	 	(a)	any act is taken by a taxing authority of the United States on or after July 28, 2015, whether or not such act is taken in relation to 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 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
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 under 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 Notes pursuant to their terms. 


  
 R-7 








 Any redemption of the Notes as set forth in clauses (1) or (2) above shall be in whole, and not in

the Trustee of the date fixed for such redemption. 
 All terms used in this Note which are defined in the Indenture shall have the meanings
assigned to them in the Indenture. The Notes are governed by the laws of the State of New York.
