The 2019 Floating Rate Notes and any such Additional 2019 Floating Rate Notes would rank equally and ratably.

Section 5.03 Principal Payment Date. The principal amount of the 2019 Floating Rate Notes Outstanding (together with any accrued and unpaid interest) shall be payable in a single installment on August 19, 2019 which date shall be the Stated Maturity of the 2019 Floating Rate Notes.

Section 5.04 Interest and Interest Rates.

(a) The 2019 Floating Rate Notes will bear interest on the unpaid principal amount thereof from August 19, 2016, or from the most recent Floating Rate Interest Payment Date (as defined below) to which interest has been paid or duly provided for, until the principal amount of the 2019 Floating Rate Notes shall have been paid or duly provided for. The interest rate per annum for the 2019 Floating Rate Notes will be reset quarterly on the first day of each Floating Rate Interest Period (as defined below) and will be equal to LIBOR (as defined below) plus 0.560%, as determined by a calculation agent (the “Calculation Agent”). The Bank of New York Mellon will initially act as Calculation Agent.

The amount of interest for each day the 2019 Floating Rate Notes are Outstanding (the “Daily Interest Amount”) will be calculated by dividing the interest rate in effect for that day by 360 and multiplying the result by the principal amount of the 2019 Floating Rate Notes. The amount of interest to be paid on the 2019 Floating Rate Notes for each Floating Rate Interest Period will be calculated by adding the Daily Interest Amount for each day in the Floating Rate Interest Period.

(b) Interest on the 2019 Floating Rate Notes shall be payable quarterly in arrears on each February 19, May 19, August 19 and November 19 (each such date, a “Floating Rate Interest Payment Date”), beginning on November 19, 2016. If any Floating Rate Interest Payment Date would fall on a day that is not a Business Day, other than the Floating Rate Interest Payment Date that is also the Stated Maturity of the 2019 Floating Rate Notes, that Floating Rate Interest Payment Date will be postponed to the following day that is a Business Day, except that if such next Business Day is in a different month, then that Floating Rate Interest Payment Date will be the immediately preceding day that is a Business Day. If the Stated Maturity of the 2019 Floating Rate Notes is not a Business Day, payment of principal and interest on the 2019 Floating Rate Notes will be made on the following day that is a Business Day and no interest will accrue for the period from and after such Stated Maturity of the 2019 Floating Rate Notes. Interest on a 2019 Floating Rate Note will be paid to the Person in whose name that 2019 Floating Rate Note was registered at the close of business on the February 4, May 4, August 4 and November 4, as the case may be, whether or not a Business Day, prior to the applicable Floating Rate Interest Payment Date, except that in the case of the Floating Rate Interest Payment Date that is also the Stated Maturity of the 2019 Floating Rate Notes, the interest due on such date will be paid to the Person to whom principal is payable upon surrender of such 2019 Floating Rate Note at a Place of Payment.

(c) On each Floating Rate Interest Payment Date, the Company will pay interest for the Floating Rate Interest Period ended on the day immediately preceding such Floating Rate Interest Payment Date. “Floating Rate Interest Period” shall mean the period commencing on and including August 19, 2016 to but excluding the first Floating Rate Interest Payment Date and each successive period from and including a Floating Rate Interest Payment Date to but excluding the next Floating Rate Interest Payment Date.

(d) “LIBOR,” with respect to a Floating Rate Interest Period, shall be the rate (expressed as a percentage per annum) for deposits in United States dollars for a three-month period beginning on the second London Banking Day after the Determination Date (each as defined below) that appears on the Designated LIBOR Page (as defined below) as of 11:00 a.m., London time, on the

Determination Date. If the Designated LIBOR Page does not include this rate or is unavailable on the Determination Date, the Calculation Agent will request the principal London office of each of four major banks in the London interbank market, as selected and identified by the Company, to provide that bank’s offered quotation (expressed as a percentage per annum) as of approximately 11:00 a.m., London time, on the Determination Date to prime banks in the London interbank market for deposits in a Representative Amount (as defined below) in United States dollars for a three-month period beginning on the second London Banking Day after the Determination Date. If at least two offered quotations are so provided, LIBOR for the Floating Rate Interest Period will be the arithmetic mean of all quotations so provided. If fewer than two quotations are so provided, the Calculation Agent will request each of three major banks in New York City, as selected and identified by the Company, to provide that bank’s rate (expressed as a percentage per annum), as of approximately 11:00 a.m., New York City time, on the Determination Date for loans in a Representative Amount in United States dollars to leading European banks for a three-month period beginning on the second London Banking Day after the Determination Date. If at least two rates are so provided, LIBOR for the Floating Rate Interest Period will be the arithmetic mean of all rates so provided. If fewer than two rates are so provided, then LIBOR for the Floating Rate Interest Period will be LIBOR in effect with respect to the immediately preceding Floating Rate Interest Period.

(e) “Designated LIBOR Page” means the display on the Reuters 3000 Xtra Service (or any successor service) on the “LIBOR01” page (or any other page as may replace such page on such service) for the purpose of displaying the London interbank rates of major banks for United States dollars.

(f) “Determination Date” with respect to a Floating Rate Interest Period will be the second London Banking Day preceding the first day of the Floating Rate Interest Period.

(g) “London Banking Day” is any day in which dealings in United States dollars are transacted or, with respect to any future date, are expected to be transacted in the London interbank market.

(h) “Representative Amount” means a principal amount that is representative for a single transaction in the relevant market at the relevant time.

(i) For purposes of the 2019 Floating Rate Notes, “Business Day” means each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day on which banking institutions in Sydney, Australia, Xxx Xxxx, Xxx Xxxx, xx Xxxxxx, Xxxxxx Xxxxxxx are authorized or obligated by law or executive order to close.

(j) All calculations of the Calculation Agent, in the absence of manifest error, will be conclusive for all purposes and binding on the Company and on the Holders of the 2019 Floating Rate Notes. In no event shall the interest rate on the 2019 Floating Rate Notes be higher than the maximum rate permitted by New York law, as the same may be modified by United States law of general application. The Calculation Agent will, upon the request of any Holder of the 2019 Floating Rate Notes, provide the rate of interest then in effect.

(k) All percentages resulting from any of the calculations in this Article V will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards (e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards).

The Place of Payment where the 2019 Floating Rate Notes may be presented or surrendered for payment, where the 2019 Floating Rate Notes may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the 2019 Floating Rate Notes and the Indenture may be served initially shall be the Corporate Trust Office of the Trustee maintained for that purpose in the Borough of Manhattan, City of New York.

(a) The 2021 Floating Rate Notes will bear interest on the unpaid principal amount thereof from August 19, 2016, or from the most recent Floating Rate Interest Payment Date (as defined below) to which interest has been paid or duly provided for, until the principal amount of the 2021 Floating Rate Notes shall have been paid or duly provided for. The interest rate per annum for the 2021 Floating Rate Notes will be reset quarterly on the first day of each Floating Rate Interest Period (as defined below) and will be equal to LIBOR (as defined below) plus 0.850%, as determined by a calculation agent (the “Calculation

Agent”). The Bank of New York Mellon will initially act as Calculation Agent. The amount of interest for each day the 2021 Floating Rate Notes are Outstanding (the “Daily Interest Amount”) will be calculated by dividing the interest rate in effect for that day by 360 and multiplying the result by the principal amount of the 2021 Floating Rate Notes. The amount of interest to be paid on the 2021 Floating Rate Notes for each Floating Rate Interest Period will be calculated by adding the Daily Interest Amount for each day in the Floating Rate Interest Period.

(b) Interest on the 2021 Floating Rate Notes shall be payable quarterly in arrears on each February 19, May 19, August 19 and November 19 (each such date, a “Floating Rate Interest Payment Date”), beginning on November 19, 2016. If any Floating Rate Interest Payment Date would fall on a day that is not a Business Day, other than the Floating Rate Interest Payment Date that is also the Stated Maturity of the 2021 Floating Rate Notes, that Floating Rate Interest Payment Date will be postponed to the following day that is a Business Day, except that if such next Business Day is in a different month, then that Floating Rate Interest Payment Date will be the immediately preceding day that is a Business Day. If the Stated Maturity of the 2021 Floating Rate Notes is not a Business Day, payment of principal and interest on the 2021 Floating Rate Notes will be made on the following day that is a Business Day and no interest will accrue for the period from and after such Stated Maturity of the 2021 Floating Rate Notes. Interest on a 2021 Floating Rate Note will be paid to the Person in whose name that 2021 Floating Rate Note was registered at the close of business on the February 4, May 4, August 4 and November 4, as the case may be, whether or not a Business Day, prior to the applicable Floating Rate Interest Payment Date, except that in the case of the Floating Rate Interest Payment Date that is also the Stated Maturity of the 2021 Floating Rate Notes, the interest due on such date will be paid to the Person to whom principal is payable upon surrender of such 2021 Floating Rate Note at a Place of Payment.

Designated LIBOR Page (as defined below) as of 11:00 a.m., London time, on the Determination Date. If the Designated LIBOR Page does not include this rate or is unavailable on the Determination Date, the Calculation Agent will request the principal London office of each of four major banks in the London interbank market, as selected and identified by the Company, to provide that bank’s offered quotation (expressed as a percentage per annum) as of approximately 11:00 a.m., London time, on the Determination Date to prime banks in the London interbank market for deposits in a Representative Amount (as defined below) in United States dollars for a three-month period beginning on the second London Banking Day after the Determination Date. If at least two offered quotations are so provided, LIBOR for the Floating Rate Interest Period will be the arithmetic mean of all quotations so provided. If fewer than two quotations are so provided, the Calculation Agent will request each of three major banks in New York City, as selected and identified by the Company, to provide that bank’s rate (expressed as a percentage per annum), as of approximately 11:00 a.m., New York City time, on the Determination Date for loans in a Representative Amount in United States dollars to leading European banks for a three-month period beginning on the second London Banking Day after the Determination Date. If at least two rates are so provided, LIBOR for the Floating Rate Interest Period will be the arithmetic mean of all rates so provided. If fewer than two rates are so provided, then LIBOR for the Floating Rate Interest Period will be LIBOR in effect with respect to the immediately preceding Floating Rate Interest Period.

(f) “Determination Date” with respect to a Floating Rate Interest Period will be the second London Banking Day preceding the first day of the Floating Rate Interest Period.

(g) “London Banking Day” is any day in which dealings in United States dollars are transacted or, with respect to any future date, are expected to be transacted in the London interbank market.

(h) “Representative Amount” means a principal amount that is representative for a single transaction in the relevant market at the relevant time.

(i) For purposes of the 2021 Floating Rate Notes, “Business Day” means each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day on which banking institutions in Sydney, Australia, Xxx Xxxx, Xxx Xxxx, xx Xxxxxx, Xxxxxx Xxxxxxx are authorized or obligated by law or executive order to close.

(j) All calculations of the Calculation Agent, in the absence of manifest error, will be conclusive for all purposes and binding on the Company and on the Holders of the 2021 Floating Rate Notes. In no event shall the interest rate on the 2021 Floating Rate Notes be higher than the maximum rate permitted by New York law, as the same may be modified by United States law of general application. The Calculation Agent will, upon the request of any Holder of the 2021 Floating Rate Notes, provide the rate of interest then in effect.

(k) All percentages resulting from any of the calculations in this Article VI will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards (e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards).

Section 6.05 Place of Payment. The Place of Payment where the 2021 Floating Rate Notes may be presented or surrendered for payment, where the 2021 Floating Rate Notes may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the 2021 Floating Rate Notes and the Indenture may be served initially shall be the Corporate Trust Office of the Trustee maintained for that purpose in the Borough of Manhattan, City of New York.

Section 6.06 Redemption. The Company shall not have the right to redeem the 2021 Floating Rate Notes other than pursuant to Section 10.8 of the Indenture.

Section 6.07 No Sinking Fund. The 2021 Floating Rate Notes are not entitled to the benefit of any sinking fund.

Section 6.08 Form. The 2021 Floating Rate Notes shall be issued initially as Registered Securities (as defined in the Indenture) in the form of one or more permanent notes in global form, without coupons, substantially in the form attached hereto as Exhibit E, deposited with The Bank of New York Mellon, as custodian for the Depositary, duly executed by the Company and authenticated by the Trustee as provided in the Indenture.

Section 6.09 Denomination. The 2021 Floating Rate Notes shall be issuable only in denominations of US$2,000 and integral multiples of US$1,000 in excess thereof. The 2021 Floating Rate Notes shall be numbered, lettered, or otherwise distinguished in such manner or in accordance with such plans as the Officers of the Company executing the same may determine with the approval of the Trustee.

Section 6.10 Depositary. The Depository Trust Company shall be the initial Depositary for the 2021 Floating Rate Notes, until a successor shall have been appointed and become such pursuant to the applicable provisions of the Indenture, and thereafter,

“Depositary” shall mean or include such successor.

Section 6.11 Defeasance; Discharge. The provisions of Sections 4.3, 4.4, 4.5 and 4.6 of the Indenture will apply to the 2021 Floating Rate Notes.

Section 6.12 Defined Terms. Terms specifically defined in this Article VI shall only relate to the 2021 Floating Rate Notes and shall have no bearing on any other series of notes referenced in this Sixteenth Supplemental Indenture.

(FORM OF REVERSE OF NOTE)

This Note is one of a duly authorized series of securities of the Company, issued and to be issued in one or more series under and pursuant to a Senior Indenture, dated as of July 1, 1999 (the “Base Indenture”), duly executed and delivered between the Company and The Bank of New York Mellon, as successor to The Chase Manhattan Bank, as trustee (the “Trustee”, which term includes any successor trustee under the Indenture), as supplemented and amended by the First Supplemental Indenture, dated as of August 27, 2009, between the Company and the Trustee (the “First Supplemental Indenture”) and the Fifth Supplemental Indenture, dated as of August 14, 2012, between the Company and the Trustee (the “Fifth Supplemental Indenture”; the Base Indenture as amended and supplemented by the First Supplemental Indenture and the Fifth Supplemental Indenture is referred to herein as the “Amended Base Indenture”), and as further supplemented by the Sixteenth Supplemental Indenture, dated as of August 19, 2016, between the Company and the Trustee (the “Sixteenth Supplemental Indenture”; the Amended Base Indenture, as further supplemented by the Sixteenth Supplemental Indenture, is referred to herein as the “Indenture”), to which Indenture and all Indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. This Note is one of a series of securities designated on the face hereof (the “Notes”). The Notes are issued pursuant to the Indenture and are limited in aggregate principal amount to US$1,500,000,000; provided, however, that the Company may from time to time, without the consent of the Holders of the Notes, create and issue additional notes having the same terms and conditions as the Notes in all respects or in all respects except for issue date, issue price and, if applicable, the first date on which interest accrues and the first payment of interest thereon. Additional notes issued in this manner will be consolidated with, and will form a single series with, the Notes, unless such additional notes will not be treated as fungible with the Notes for U.S. federal income tax purposes. The Notes and any such additional notes would rank equally and ratably.

In accordance with Section 10.8 of the Indenture, pursuant to the procedure set forth in Article X of the Indenture, the Company may, at its option, redeem all, but not less than all, of the Notes if (a) there is a change in or any amendment to the laws or regulations (i) of the Commonwealth of Australia, or any political subdivision or taxing authority thereof or therein, or (ii) in the event of the assumption pursuant to Section 7.1 of the Indenture of the obligations of the Company under the Indenture and this Note by an entity organized under the laws of a country other than the Commonwealth of Australia or a political subdivision of a country other than the Commonwealth of Australia, of the Commonwealth of Australia or the country in which such entity is organized or resident or deemed resident for tax purposes or any political subdivision or taxing authority thereof or therein, or (b) there is a change in any application or interpretation of any such laws or regulations, which change or amendment becomes

A-4

effective, (i) with respect to taxes imposed by the Commonwealth of Australia or any political subdivision or taxing authority thereof or therein, on or after the date the Company originally issued this Note, or (ii) in the event of the assumption pursuant to Section 7.1 of the Indenture of the obligations of the Company under the Indenture and this Note by an entity organized under the laws of a country other than the Commonwealth of Australia or a political subdivision of a country other than the Commonwealth of Australia, with respect to taxes imposed by a non-Australian jurisdiction, on or after the date of the transaction resulting in such assumption, and, in each case, as a result of such change or amendment (1) the Company is or will become obligated to pay any Additional Amounts on this Note pursuant to Section 9.8 of the Indenture or (2) the Company would not be entitled to claim a deduction in computing its taxation liabilities in respect of (A) any payments of interest or Additional Amounts or (B) any original issue discount on this Note.

Before the Company may redeem this Note, it must give the Holder of this Note at least 30 days’ written notice and not more than 60 days’ written notice of its intention to redeem this Note, provided that if the earliest date on which (i) the Company will be obligated to pay any Additional Amounts, or (ii) the Company would not be entitled to claim a deduction in respect of any payments of interest or Additional Amounts on or any original issue discount in respect of this Note in computing its taxation liabilities, would occur less than 45 days after the relevant change or amendment to the applicable laws, regulations, determinations or guidelines, the Company may give less than 30 days’ written notice but in no case less than 15 days’ written notice, provided it gives such notice as soon as practicable in all the circumstances.

The Redemption Price for this Note shall equal 100% of the principal amount of this Note plus accrued but unpaid interest to but excluding the date of redemption.

The Indenture contains provisions for defeasance and covenant defeasance at any time of the indebtedness evidenced by this Note upon compliance by the Company with certain conditions set forth therein.

If an Event of Default shall have occurred and be continuing, the principal hereof may be declared, and upon such declaration become, due and payable immediately, in the manner, with the effect and subject to the conditions provided in the Indenture. The Indenture contains provisions permitting the Holders of not less than a majority in aggregate principal amount of the Outstanding Notes, on behalf of all of the Holders of the Notes, to waive any Event of Default under the Indenture and its consequences, subject to Section 5.7 of the Indenture.

In accordance with Section 9.8 of the Indenture, the Company will pay all amounts that it is required to pay on this Note without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or other governmental charges imposed or levied by or on behalf of the Commonwealth of Australia or any political

A-5

subdivision or taxing authority thereof or therein, unless such withholding or deduction is required by law. If the Company withholds or deducts any such amount from any payment on this Note, the Company will pay such additional amounts (the “Additional Amounts”) so that the net amounts received by the Holder of this Note, after such withholding or deduction, will equal the amounts that the Holder of this Note would have received on this Note if such withholding or deduction had not been required; provided that no Additional Amounts shall be payable for or on account of:

(1) any tax, duty, assessment or other governmental charge that would not have been imposed but for the fact that the Holder of this Note was a resident, domiciliary or national of, or engaged in business or maintained a permanent establishment or was physically present in, the Commonwealth of Australia or any political subdivision or taxing authority thereof or therein or otherwise had some connection with the Commonwealth of Australia or any political subdivision or taxing authority thereof or therein other than merely holding this Note, or receiving payments under this Note;

(2) any tax, duty, assessment or other governmental charge that would not have been imposed but for the fact that the Holder of this Note presented this Note for payment in the Commonwealth of Australia, unless the Holder was required to present this Note for payment and it could not have been presented for payment anywhere else;

(3) any tax, duty, assessment or other governmental charge that would not have been imposed but for the fact that the Holder of this Note presented this Note for payment more than 30 days after the date such payment became due and was provided for, whichever is later, except to the extent that the Holder would have been entitled to the Additional Amounts on presenting this Note for payment on any day during that 30 day period;

(4) any estate, inheritance, gift, sale, transfer, personal property or similar tax, duty, assessment or other governmental charge;

(5) any tax, duty, assessment or other governmental charge which is payable otherwise than by withholding or deduction;

(6) any tax, duty, assessment or other governmental charge that would not have been imposed if the Holder or beneficial owner of this Note complied with the Company’s request to provide information concerning his, her or its nationality, residence or identity or to make a declaration, claim or filing or satisfy any requirement for information or reporting that is required to establish the eligibility of the Holder, or the beneficial owner, of this Note to receive the relevant payment without (or at a reduced rate of) withholding or deduction for or on account of any such tax, duty, assessment or other governmental charge;

A-6

(7) any tax, duty, assessment or other governmental charge that would not have been imposed but for the Holder or beneficial owner of this Note being an associate of the Company for purposes of section 128F(6) of the Income Tax Assessment Xxx 0000 of the Commonwealth of Australia (the “Australian Tax Act”) (other than in the capacity of a clearing house, paying agent, custodian, funds manager or responsible entity of a registered managed investment scheme under the Corporations Xxx 0000 of the Commonwealth of Australia);

(8) any tax, duty, assessment or other governmental charge that is imposed or withheld as a consequence of a determination having been made under Part IVA of the Australian Tax Act (or any modification thereof or provision substituted therefore) by the Australian Commissioner of Taxation that such tax, duty, assessment or other governmental charge is payable in circumstances where the Holder or the beneficial owner of this Note is a party to or participated in a scheme to avoid such tax which the Company was not a party to;

(9) any tax, duty, assessment or other governmental charge that is imposed pursuant to European Council Directive 2003/48/EC (the “Directive”) or any law implementing or complying with, or introduced in order to conform to, such Directive, or any agreement entered into by a Member State of the European Union with (A) any other state or (B) any relevant, dependent or associated territory of any Member State of the European Union providing for measures equivalent to, or the same as, those provided for by such Directive;

(10) any tax, duty, assessment or other governmental charge arising under or in connection with sections 1471 to 1474 of the U.S. Internal Revenue Code of 1986, as amended (including any regulations or official interpretations issued, agreements entered into or non-U.S. laws enacted, with respect thereto) (“FATCA”); or

(11) any combination of the foregoing.

Subject to the foregoing, Additional Amounts will also not be payable by the Company with respect to any payment on this Note to any Holder who is a fiduciary or partnership or other than the sole beneficial owner of such payment in respect of this Note to the extent that payment would, under the laws of the Commonwealth of Australia or any political subdivision or taxing authority thereof or therein, be treated as being derived or received for tax purposes by a beneficiary or settler of that fiduciary or a member of that partnership or a beneficial owner, in each case, who would not have been entitled to those Additional Amounts had it been the actual Holder of this Note.

The Company, and any other Person to or through which any payment with respect to this Note may be made, shall be entitled to withhold or deduct from any payment with respect to this Note amounts required to be withheld or deducted under or

A-7

in connection with FATCA, and Holders and beneficial owners of this Note shall not be entitled to receive any gross up or other additional amounts on account of any such withholding or deduction.

Any reference in this Note to principal or interest shall be deemed to also refer to any Additional Amount that may be payable as provided above.

The Indenture contains provisions permitting the Company and the Trustee, with the written consent of the Holders of not less than a majority in aggregate principal amount (calculated as provided in the Indenture) of the Outstanding Securities of each series adversely affected thereby to add any provisions to or to change or eliminate any provisions of the Indenture or any supplemental indenture or to modify the rights of the Holders of the Securities of such series, provided that, without the consent of the Holder of each such Security so affected, no such modification shall (a) change the Stated Maturity of the principal of, or any installment of principal of or interest on, any Security, or reduce the principal amount of any Security or the rate of interest thereon, or change the coin or currency in which any Security or the interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity of any Security (or, in the case of redemption, on or after the Redemption Date), or (b) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any such amendment or modification, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of the Indenture or certain defaults thereunder and their consequences) provided for in the Indenture, or (c) change any obligation of the Company to maintain an office or agency in the places and for the purposes specified in Section 9.2 of the Indenture, or (d) except to the extent provided in Section 8.1(9) of the Indenture, make any change in Section 5.2, 5.7, 5.10 or 8.2 of the Indenture except to increase any percentage or to provide that certain other provisions of the Indenture cannot be modified or waived except with the consent of the Holders of each Outstanding Security affected thereby. Any such consent given by the Holder of this Note shall be conclusive and binding upon such Holder and all future Holders of this Note and of any Notes issued on registration hereof, the transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent is made upon this Note.

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 place, at the respective time, at the rate and in the coin or currency herein prescribed.

Upon surrender for registration of transfer of this Note, the Company shall execute and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, a new Note or Notes of like tenor and authorized denominations for an equal aggregate principal amount in exchange herefor, subject to the limitations provided in the Indenture. Every Note presented or surrendered for registration of

A-8

transfer or for exchange shall (if so required by the Company, the Registrar or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company, the Registrar and the Trustee duly executed by the Holder thereof or his attorney duly authorized in writing. No service charge shall be made for any 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 (subject to the provisions hereof with respect to determination of the Person to whom interest is payable).

Reference is made to the Indenture 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 to be authenticated and delivered.

No past, present or future director, officer, employee, agent, member, manager, trustee or stockholder, as such, of the Company or any successor Person shall have any liability for any obligations of the Company or any successor Person, either directly or through the Company or any successor Person, under the Notes or this Indenture or for any claim based on, in respect of or by reason of such obligations or their creation, whether by virtue of any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise. By accepting a Note, each Holder agrees to the provisions of Section 1.13 of the Indenture and waives and releases all such liability. Such waiver and release shall be part of the consideration for the issue of the Notes.

The Notes of this series shall be issuable only in denominations of US$2,000 and integral multiples of US$1,000 in excess thereof. [This Global Note is exchangeable for Notes in definitive form only under certain limited circumstances set forth in the Indenture.](2) At the option of the Holder, the Notes (except a Note in global form) may be exchanged for other Notes, of any authorized denominations and of a like aggregate principal amount containing identical terms and provisions, upon surrender of the Notes to be exchanged at such office or agency.

FLOATING RATE NOTE DUE AUGUST 19, 2019

(1) Insert in Global Notes only

D-1

successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to or registered assigns, the principal sum of (US$ ) on August 19, 2019 (the “Stated Maturity”). This Note will bear interest on the unpaid principal amount hereof from August 19, 2016, or from the most recent Interest Payment Date (as defined below) to which interest has been paid or duly provided for, until the principal amount hereof shall have been paid or duly provided for. The interest rate per annum on this Note will be reset quarterly on the first day of each Interest Period (as defined below) and will be equal to LIBOR (as defined below) plus 0.560%, as determined by a calculation agent (the “Calculation Agent”). The Bank of New York Mellon will initially act as Calculation Agent. The amount of interest for each day this Note is Outstanding (the “Daily Interest Amount”) will be calculated by dividing the interest rate in effect for that day by 360 and multiplying the result by the principal amount of this Note. The amount of interest to be paid on this Note for each Interest Period will be calculated by adding the Daily Interest Amount for each day in the Interest Period.

Interest on this Note shall be payable quarterly in arrears on each February 19, May 19, August 19 and November 19 (each such date, an “Interest Payment Date”), beginning on November 19, 2016. If any Interest Payment Date would fall on a day that is not a Business Day, other than the Interest Payment Date that is also the Stated Maturity for this Note, that Interest Payment Date will be postponed to the following day that is a Business Day, except that if such next Business Day is in a different month, then that Interest Payment Date will be the immediately preceding day that is a Business Day. If the Stated Maturity for this Note is not a Business Day, payment of principal and interest on this Note will be made on the following day that is a Business Day and no interest will accrue for the period from and after such Stated Maturity.

On each Interest Payment Date, the Company will pay interest for the Interest Period ended on the day immediately preceding such Interest Payment Date. “Interest Period” shall mean the period commencing on and including August 19, 2016 to but excluding the first Interest Payment Date and each successive period from and including an Interest Payment Date to but excluding the next Interest Payment Date.

“LIBOR,” with respect to an Interest Period, shall be the rate (expressed as a percentage per annum) for deposits in United States dollars for a three-month period beginning on the second London Banking Day after the Determination Date (each as defined below) that appears on the Designated LIBOR Page (as defined below) as of 11:00 a.m., London time, on the Determination Date. If the Designated LIBOR Page does not include this rate or is unavailable on the Determination Date, the Calculation Agent will request the principal London office of each of four major banks in the London interbank market, as selected and identified by the Company, to provide that bank’s offered quotation (expressed as a percentage per annum) as of approximately 11:00 a.m., London time, on the Determination Date to prime banks in the London interbank market

D-2

for deposits in a Representative Amount (as defined below) in United States dollars for a three-month period beginning on the second London Banking Day after the Determination Date. If at least two offered quotations are so provided, LIBOR for the Interest Period will be the arithmetic mean of all quotations so provided. If fewer than two quotations are so provided, the Calculation Agent will request each of three major banks in New York City, as selected and identified by the Company, to provide that bank’s rate (expressed as a percentage per annum), as of approximately 11:00 a.m., New York City time, on the Determination Date for loans in a Representative Amount in United States dollars to leading European banks for a three-month period beginning on the second London Banking Day after the Determination Date. If at least two rates are so provided, LIBOR for the Interest Period will be the arithmetic mean of all rates so provided. If fewer than two rates are so provided, then LIBOR for the Interest Period will be LIBOR in effect with respect to the immediately preceding Interest Period.

“Designated LIBOR Page” means the display on the Reuters 3000 Xtra Service (or any successor service) on the “LIBOR01” page (or any other page as may replace such page on such service) for the purpose of displaying the London interbank rates of major banks for United States dollars.

“Determination Date” with respect to an Interest Period will be the second London Banking Day preceding the first day of the Interest Period.

“London Banking Day” is any day in which dealings in United States dollars are transacted or, with respect to any future date, are expected to be transacted in the London interbank market.

“Representative Amount” means a principal amount that is representative for a single transaction in the relevant market at the relevant time.

“Business Day” means each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day on which banking institutions in Sydney, Australia, Xxx Xxxx, Xxx Xxxx, xx Xxxxxx, Xxxxxx Xxxxxxx are authorized or obligated by law or executive order to close.

All calculations of the Calculation Agent, in the absence of manifest error, will be conclusive for all purposes and binding on the Company and on the Holder of this Note. In no event shall the interest rate on this Note be higher than the maximum rate permitted by New York law, as the same may be modified by United States law of general application. The Calculation Agent will, upon the request of any Holder of this Note, provide the rate of interest then in effect.

All percentages resulting from any of the above calculations will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-

D-3

millionths of a percentage point rounded upwards (e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards).

Interest on this Note which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the close of business on the February 4, May 4, August 4, or November 4 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date, at the office or agency maintained for such purpose pursuant to the Indenture; provided, however, that at the option of the Company, interest on this Note may be paid (i) by check mailed to the address of the Person entitled thereto as it shall appear on the Register or (ii) to a Holder of US$1,000,000 or more in aggregate principal amount of the Notes by wire transfer to an account maintained by the Person entitled thereto as specified in the Register. Any interest on this Note which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest shall instead be payable to the Person in whose name this Note is registered on the Special Record Date or other specified date in accordance with the Indenture. Notwithstanding the foregoing, interest payable on an Interest Payment Date that is also the Stated Maturity of this Note will be paid at such office or agency to the Person to whom the principal hereof is payable, upon surrender of this Note at such office or agency.

The provisions of this Note are continued on the reverse side hereof and such continued provisions shall for all purposes have the same effect as though fully set forth at this place.
