 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 $500,000,000 on April 25, 2022 and to pay interest thereon from and including April 25, 2017 or from the
most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually, on April 25th and October 25th of each year, commencing October 25, 2017 at the rate of 2.750% 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 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 ten 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 ten 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, 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 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. 

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

 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 from time to time, 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 $2,250,000,000. 
 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. 

Sections 12.02 and 12.03 of the Indenture containing provisions for defeasance apply to this Note. At any time the entire indebtedness of this
Note may be defeased upon compliance by the Company with certain conditions set forth in Section 12.04 of the Indenture. 
 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 the rights, duties or immunities of the Trustee unless the Trustee agrees to such modification. 

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. 

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 and the Company is unable to appoint a
successor depository, 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. 
 (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 private foundation or other foreign tax-exempt organization; 

(c) passive foreign investment company; 

(d) controlled foreign corporation or 

(e) 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. 
 (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. 

(10) Additional Amounts will not be payable if a payment on a Note is reduced as a result of any: 

(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 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. 
 (13)
Additional Amounts will not be payable if a payment on a Note is reduced as a result of any combination of items (1) through (12) 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. 

As used in this Note, “United States person” means: 
  

	 	(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 or any political subdivision thereof; 

 

	 	(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 (i) 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; or (ii) it has a valid election in effect under applicable United States Treasury regulations to be treated as a United States person. 

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. 

Except as provided below, the Notes may not be redeemed prior to maturity. 

 

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

  

	 	(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 April 18, 2017 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 April 18, 2017 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
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 Notes pursuant to their terms. 

Any redemption of the 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 Notes Outstanding plus accrued interest thereon to the date of redemption. 
  

	 	(3)	The Company may also redeem the Notes, at its option, in whole at any time or in part from time to time, on or after October 25, 2017 and prior to March 25, 2022, at a redemption price equal to the sum of (i)
100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to, but excluding the date of redemption; and (ii) the Make-Whole Amount, if any, with respect to such Notes. The Reinvestment Rate will equal the
Treasury Yield calculated to March 25, 2022, plus 0.200%. 

  

	 	•	 	“Make-Whole Amount” means the excess, if any, of: (i) the aggregate present value as of the date of such redemption of each dollar of principal being redeemed and the amount of interest (exclusive of
interest accrued to the date of redemption) that would have been payable in respect of each such dollar if such redemption had not been made, determined by discounting, on a semi-annual basis, such principal and interest at the Reinvestment Rate (as
defined below) (determined on the third business day preceding the date that notice of such redemption is given) from the respective dates on which such principal and interest would have been payable if such redemption had not been made, to the date
of redemption, over (ii) the aggregate principal amount of the debt securities being redeemed. 

  

	 	•	 	“Reinvestment Rate” means the yield on Treasury securities at a constant maturity corresponding to the remaining life (as of the date of redemption, and rounded to the nearest month) to March 25, 2022, of
the principal being redeemed (the “Treasury Yield”), plus 0.200%. For purposes of the Notes, the Treasury Yield shall be equal to the arithmetic mean of the yields published in the Statistical Release (as defined below) under the heading
“Week Ending” for “U.S. Government Securities — Treasury Constant Maturities” with a maturity equal to such remaining life; provided that if no published maturity exactly corresponds to such remaining life, then the Treasury
Yield shall be interpolated or extrapolated on a straight-line basis from the arithmetic means of the yields for the next shortest and next longest published maturities. For purposes of calculating the Reinvestment Rate, the most recent Statistical
Release published prior to the date of determination of the Make-Whole Amount shall be used. If the format or content of the Statistical Release changes in a manner that precludes determination of the Treasury Yield in the above manner, then the
Treasury Yield shall be determined in the manner that most closely approximates the above manner, as reasonably determined by the Company. 

  

	 	•	 	 “Statistical Release” means the statistical release designated “H.15(519)” or any successor
publication which is published weekly by the Federal Reserve and which reports yields on actively traded United States government securities adjusted to constant 

	 	 
maturities or, if such statistical release is not published at the time of any determination under the Indenture, then such other reasonably comparable index which shall be designated by the
Company. 

  

	 	(4)	The Company may also redeem the Notes, at its option, in whole, but not in part, on or after March 25, 2022 at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and
unpaid interest thereon to, but excluding, the date of redemption. 

 Holders shall be given not less than 15 days nor more than 60 days prior
notice by the Trustee of the date fixed for such redemption described in (1) through (4) above. 
 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.

Section 1.Defined Terms.  Each capitalized term which is defined in the Credit Agreement, but which is not defined in this Sixth Amendment, shall have the meaning ascribed to such term in the Credit Agreement (as amended hereby).  Unless otherwise indicated, all section references in this Sixth Amendment refer to the Credit Agreement.

Section 2.Amendment to Section 2.07(e) of the Credit Agreement.  In reliance on the representations, warranties, covenants and agreements contained in this Sixth Amendment, and subject to the satisfaction of the conditions precedent set forth in Section 4 hereof, Section 2.07(e) of the Credit Agreement is hereby amended, effective as of the Sixth Amendment Effective Date, by replacing the reference to “April 1, 2017” appearing in clause (y) of the third sentence of Section 2.07(e), with “October 1, 2017”. 

Section 3.Borrowing Base Redetermination.  Subject to the satisfaction of the conditions precedent set forth in Section 4 hereof, Administrative Agent and the Lenders hereby agree that for the period from and including the Sixth Amendment Effective Date to but excluding the next Redetermination Date, the amount of the Borrowing Base shall be increased to $1,400,000,000 (the “April 2017 Redetermination”).  Administrative Agent, the Lenders and Borrower agree that the foregoing constitutes the April 1, 2017 Scheduled Redetermination and 

1

Notwithstanding the foregoing, the Borrowing Base may be subject to further redeterminations and adjustments from time to time pursuant to Section 2.07 or Section 8.12(c).  The Aggregate Commitment shall remain equal to $1,050,000,000.

The execution, delivery and effectiveness of this Sixth Amendment shall not, except as expressly provided herein, operate as a waiver of any right, power or remedy of any Lender or the Administrative Agent under any of the Loan Documents, nor constitute a waiver of any provision of any of the Loan Documents.

Each of the Credit Parties hereby expressly (a) acknowledges the terms of this Sixth Amendment, (b) ratifies and affirms its obligations under the Guaranty Agreement and the other Loan Documents to which it is a party, (c) acknowledges, renews and extends its continued liability under the Guaranty Agreement and the other Loan Documents to which it is a party (in each case, as amended hereby), and (d) acknowledges
