this Section. 
 The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a
witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged 

  

 15 








 
to him or her the execution thereof. Where such execution is by a signer acting in a capacity other than his or her individual capacity, such certificate or

making of any notice, declaration, request or direction referred to in the next paragraph. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders
of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Company or the Guarantors from setting a new record date for any action for which a record
date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render
ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company or any
Guarantor, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the relevant series in the manner set
forth in Section 106.

Section 507(2) or (iv) any direction referred to in Section 512, in each case with respect to Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of such series on
such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder
unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a
new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in
this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant
to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder of Securities of the
relevant series in the manner set forth in Section 106. 
 With respect to any record date set pursuant to this Section, the party
hereto which sets such record dates may designate any day as the “Expiration Date” and from time to time may change the Expiration Date to any 

  

 16 








 
earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other parties
hereto in writing, and to each Holder of Securities of the relevant series in the manner set forth in Section 106, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant
to this Section, the party hereto which set such record date shall be deemed to have initially designated the 90th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. 
 Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular
Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount.

 Section 105. Notices, Etc., to Trustee, Company and Guarantors.

furnished or filed or mailed first-class postage prepaid in writing to or with the Trustee at its Corporate Trust Office, Attention: Structured Finance, BHP Billiton Finance, or

herein expressly provided) if in writing and mailed to the Company or such Guarantor, international air mail postage prepaid and addressed to such party at its respective registered office specified in the first paragraph of this instrument to the
attention of its Secretary, or at such other registered address previously furnished in writing to the Trustee by the Company or such Guarantor. 
 Section 106. Notice to Holders; Waiver.  
 Where this Indenture provides for notice to Holders of any event, such notice
shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at the Holder’s address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so
mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice,
either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver. 
 In case by reason of the suspension of regular mail service or by reason of any other cause it shall be
impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. 
 Section 107. Language of Notices, Etc.  
 Any
request, demand, authorization, direction, notice, consent or waiver required or permitted under this Indenture shall be in the English language, except that any published notice may be in an official language of the country of publication.

 Section 108. Conflict with Trust Indenture Act.

 17 








 
provision of this Indenture modifies or excludes any provision of the Trust Indenture Act which may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or to be excluded, as the case may be.

states that such provision shall apply in lieu of this Section)) payment of interest or principal (and premium, if any) need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of
Payment with the same force and effect as if made on the Interest Payment Date or Redemption Date, or at the Stated Maturity; provided that no interest shall accrue on such payment for the period from and after such Interest Payment Date, Redemption

successor’s acceptance of such appointment. The Company and each of the Guarantors further agree to take any and all action, including the execution and filing of any and all such documents and instruments, as may be necessary to continue such

institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or
any premium or interest hereon on or after the respective due dates expressed herein. 
 No reference herein to the Indenture and no
provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the
coin or currency, herein prescribed.

connection therewith. 
 Prior to due presentment of this Security for registration of transfer or exchange, the Company, the Guarantors, the

taxes, duties, assessments or governmental charges payable in respect of such) in the payment to each Holder of a Security of the amounts which would have been payable in respect of such Security or the Guarantee thereof, as the case may be, had no
such withholding or deduction been required, except that no Additional Amounts shall be so payable for or on account of: 
 (a) any tax, assessment or other governmental charge which would not have been imposed but for (i) the existence of any present or former connection between such Holder (or between a fiduciary, settlor, beneficiary, member or
shareholder of, or possessor of a power over, such Holder, if such Holder is an estate, trust, partnership or corporation) and the taxing jurisdiction or any political subdivision or territory or possession thereof or area subject to its
jurisdiction, including, without limitation, such Holder (or such fiduciary, settlor, beneficiary, member, shareholder or possessor) being or having been a citizen or resident thereof or being or having been present or engaged in trade or business

beneficial owner of a Security with a request of the Company or the applicable Guarantor addressed to the Holder (i) to provide information concerning the nationality, residence or identity of the Holder or such beneficial owner or (ii) to
make any declaration or other similar claim or satisfy any information or reporting requirement, which, in the case of (i) or (ii), is required or imposed by a statute, treaty, regulation or administrative practice of the taxing jurisdiction as

Act of 1936 of Australia (the “Australian Tax Act”) and which, among other things, includes amounts in the nature of, or in substitution for, interest) payable on the debt security because the Holder of a Security is an
“associate” of the Company (as that term is defined in section 128F(9) of the Australian Tax Act);

 (j) any withholding or deduction for which a determination is made by the Australian
Commissioner of Taxation that the withholding or deduction is payable because the Holder has participated in a scheme to avoid withholding tax provided that neither the Company nor any Guarantor participated in or was a party to such scheme; or

 (k) any combination of items (a), (b), (c), (d), (e), (f), (g), (h), (i) or (j);

in the income for tax purposes of a beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to such Additional Amounts had it been the Holder of the Security.

 Each of the Guarantors hereby agrees that its obligations hereunder shall be as if it were principal debtor and not merely surety, and
shall be absolute and unconditional, irrespective of, and shall be unaffected by, any invalidity, irregularity or unenforceability of such Security or such Indenture, any failure to enforce the provisions of such Security or such Indenture, or any
waiver, modification or indulgence granted to the Company with respect thereto, by the Holder of such Security or the Trustee or any other circumstance which may otherwise constitute a legal or equitable discharge of a surety or guarantor;
provided, however, that, notwithstanding the foregoing, no such waiver, modification or indulgence shall, without the consent of each of the Guarantors, increase the principal amount of such Security, or increase the interest rate thereon, or
increase any premium payable upon redemption thereof, or alter the Stated Maturity thereof, or increase the principal amount of any Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the maturity
thereof pursuant to Section 502 of such Indenture. Each of the Guarantors hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of a merger or bankruptcy of the Company, any right to require a
proceeding first against the Company, protest or notice with respect to such Security or the indebtedness evidenced thereby or with respect to any sinking fund or analogous payment require under such Security and all demands whatsoever, and
covenants that this Guarantee will not be discharged except by payment in full of the principal of, premium, if any, and interest on such Security. 
 Each of the Guarantors shall be subrogated to all rights of the Holder of such Security and the Trustee against the Company in respect of any amounts paid to such Holder by such Guarantor pursuant to the provisions of this Guarantee,
provided, however, that such Guarantor shall not be entitled to enforce, or to receive any payments arising out of or based upon, such right of subrogation until the principal of, premium, if any, and interest on all Securities of the
same series issued under such Indenture shall have been paid in full. 
 No reference herein to such Indenture and no provision of this
Guarantee or of such Indenture shall alter or impair the guarantee of the Guarantors, which is absolute and unconditional, of the due and punctual payment of the principal of, premium, if any, and interest on, and any sinking fund or analogous
payments with respect to, the Security upon which this Guarantee is endorsed. 
 This Guarantee shall not be valid or obligatory for any
purpose until the certificate of authentication of such Security shall have been manually executed by or on behalf of the Trustee under such Indenture. 
 All terms used in this Guarantee which are defined in such Indenture shall have the meanings assigned to them in such Indenture. 
 The Guarantee shall be deemed to be a contract made under the laws of the State of New York, and for all purposes shall be governed by and construed in accordance with the law of the State of New York.

form a single series with the outstanding Securities of any series or upon such terms as the Company may determine at the time of their issue; and 
 (22) any other terms of the series (which terms shall not be inconsistent with the provisions of this Indenture, except as permitted by Section 901(5)). 
 All Securities of any one series shall be substantially identical except as to denomination and except as may otherwise be provided in or pursuant to the
Board Resolution referred to above and (subject to Section 303) set forth, or determined in the manner provided, in the Officer’s Certificate referred to above or in any such indenture supplemental hereto. 
 If any of the terms of the Securities of any series are established by action taken pursuant to a Board Resolution of the Company or any Guarantor, a
copy of an appropriate record of such action shall be certified by 

  

 30 








 
the Secretary or an Assistant Secretary of the Company or by any Director or the Secretary or an Assistant Secretary of any Guarantor, as the case may be and
delivered to the Trustee at or prior to the delivery of the Officer’s Certificate setting forth the terms of the series. 
 Section 302.
Denominations. 
 The Securities of each series shall be issuable only in registered form without coupons and only in such
denominations as shall be specified as contemplated by Section 301. In the absence of any such specified denomination with respect to the Securities of any series, the Securities of such series shall be issuable in denominations of $1,000 and
any integral multiple thereof. 
 Section 303. Execution, Authentication, Delivery and Dating.  
 The Securities shall be executed on behalf of the Company by its Chairman of the Board, its Deputy Chairman of the Board, its Chief Executive Officer or
one of its Vice Presidents, or any other duly authorized officer of the Company or any other person specifically authorized by the Board of Directors. The signature of any of these officers or authorized persons on the Securities may be manual or
facsimile. 
 Securities or Guarantees bearing the manual or facsimile signatures of individuals who were at any time the proper officers of
the Company or the relevant Guarantor, as the case may be, shall bind the Company, or the relevant Guarantor, as the case may be, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and
delivery of such Securities or the delivery of such Guarantees or did not hold such offices at the date of such Securities or Guarantees. 
 At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company and having endorsed thereon Guarantees to the Trustee for authentication,
together with a Company Order for the authentication and delivery of such Securities and a Company Order from any Guarantor approving the delivery of the Guarantees endorsed thereon, and the Trustee in accordance with the Company Order shall
authenticate and make available for delivery such Securities having such Guarantees endorsed thereon. If the form or terms of the Securities of the series and the Guarantees have been established by or pursuant to one or more Board Resolutions as
permitted by Sections 201 and 301, in authenticating such Securities and Guarantees, and accepting the additional responsibilities under this Indenture in relation to such Securities and Guarantees, the Trustee shall be entitled to receive, and
(subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating, 
 (1) if the forms of
such Securities and Guarantees have been established by or pursuant to Board Resolution as permitted by Section 201, that such forms have been established in conformity with the provisions of this Indenture; 
 (2) if the terms of such Securities and Guarantees have been established by or pursuant to Board Resolution as permitted by
Section 301, that such terms have been established in conformity with the provisions of this Indenture; and 
 (3) that
such Securities and Guarantees, when authenticated and made available for delivery by the Trustee and issued by the Company and the Guarantors in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid
and legally binding obligations of the Company and the Guarantors enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or
affecting creditors’ rights and to general equity principles. 
 If such form or terms have been so established, the Trustee shall not be required to
authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably
acceptable to the Trustee. 
  

 31 








 Notwithstanding the provisions of Section 301 and of the preceding paragraph, if all Securities of a
series are not to be originally issued at one time, it shall not be necessary to deliver the Officer’s Certificate otherwise required pursuant to Section 301 or the Company Order and Opinion of Counsel otherwise required pursuant to such
preceding paragraph at or prior to the authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued. 
 Each Security shall be dated the date of its authentication. 
 No Security or Guarantee shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form
provided for herein executed by the Trustee by manual or facsimile signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security or Guarantee has been duly authenticated and delivered
hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in
Section 309, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture. 
 The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantees endorsed thereon
on behalf of the Guarantors. 
 Section 304. Temporary Securities.  
 Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee shall authenticate and make available for delivery, temporary Securities which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities and having endorsed thereon Guarantees of the Guarantors, substantially in the tenor of the
definitive Guarantees in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities.

 If temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without
unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at
the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the Company shall execute and the Trustee shall
authenticate and make available for delivery in exchange therefor one or more definitive Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount which have endorsed thereon the Guarantees of
the Guarantors. Until so exchanged, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series and tenor. 
 Section 305. Registration, Registration of Transfer and Exchange.  
 The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company in a Place of Payment being herein
sometimes collectively referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The Trustee
is hereby appointed “Security Registrar” for the purpose of registering Securities and transfers of Securities as herein provided. 
 Upon surrender for registration of transfer of any Security of a series at the office or agency of the Company in a Place of Payment for that series, the Company shall execute, and the Trustee shall authenticate and make 

  

 32 








 
available for delivery, in the name of the designated transferee or transferees, one or more new Securities of the same series, of any authorized
denominations and of like tenor and aggregate principal amount, each such Security having endorsed thereon Guarantees of the Guarantors. 
 At the option of the Holder, Securities of any series may be exchanged for other Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount, each such Security having endorsed thereon
Guarantees of the Guarantors, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and make available for
delivery, the Securities which the Holder making the exchange is entitled to receive. 
 All Securities issued upon any registration of
transfer or exchange of Securities shall be the valid obligations of the Company and the Guarantors, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities and Guarantees surrendered upon such
registration of transfer or exchange. 
 Every Security presented or surrendered for registration of transfer or for exchange shall (if so
required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or the Holder’s attorney duly
authorized in writing or by facsimile. 
 No service charge shall be made for any registration of transfer or exchange of Securities, but the
Company or the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to
Section 304, 906 or 1107 not involving any transfer. 
 If the Securities of any series (or of any series and specified tenor) are to be
redeemed in part, the Company shall not be required (A) to issue, register the transfer of or exchange any Securities of that series (or of that series and specified tenor, as the case may be) during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of any such Securities selected for redemption under Section 1103 and ending at the close of business on the day of such mailing, or (B) to register the transfer of
or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. 
 The provisions of Clauses (1), (2), (3) and (4) below shall apply only to Global Securities: 
 (1) Each
Global Security authenticated under this Indenture shall be registered in the name of the Depositary designated for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such
Global Security shall constitute a single Security for all purposes of this Indenture. 
 (2) Notwithstanding any other
provision in this Indenture, no Global Security may be exchanged in whole or in part for Securities registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the Depositary for such
Global Security or a nominee thereof unless (A) such Depositary (i) has notified the Company and the Guarantors that it is unwilling or unable to continue as Depositary for such Global Security or (ii) has ceased to be a clearing agency
registered under the Exchange Act, (B) there shall have occurred and be continuing an Event of Default with respect to such Global Security or (C) there shall exist such circumstances, if any, in addition to or in lieu of the foregoing as
have been specified for this purpose as contemplated by Section 301. 
 (3) Subject to Clause (2) above, any
exchange of a Global Security for other Securities may be made in whole or in part, and all Securities issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall
direct. 
  

 33 








 (4) Every Security authenticated and made available for delivery upon registration of
transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this Section, Section 304, 306, 906 or 1107 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global
Security, unless such Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof. 
 Section 306. Mutilated, Destroyed, Lost and Stolen Securities.  
 If any mutilated Security is surrendered to the
Trustee, the Company shall execute and the Trustee shall authenticate and make available for delivery in exchange therefore a new Security of the same series and of like tenor and principal amount having endorsed thereon Guarantees and bearing a
number not contemporaneously outstanding. 
 If there shall be delivered to the Company and the Trustee (i) evidence to their
satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company, any
Guarantor or the Trustee that such Security has been acquired by a protected purchaser, the Company shall execute and the Trustee shall authenticate and make available for delivery, in lieu of any such destroyed, lost or stolen Security, a new
Security of the same series and of like tenor and principal amount having endorsed thereon a Guarantee and bearing a number not contemporaneously outstanding. 
 In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security. 
 Upon the issuance of any new Security under this Section, the Company or the Trustee may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 
 Every new Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company and the Guarantors,
whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued
hereunder. 
 The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with
respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 
 Section 307. Payment of Interest; Interest Rights
Preserved.  
 Except as otherwise provided as contemplated by Section 301 with respect to any series of Securities, interest on any
Security 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 that Security (or one or more Predecessor Securities) is registered at the close of business on the
Regular Record Date for such interest and, at the option of the Company, may be paid by check mailed to the address of the Person as it appears in the Security Register. 
 Any interest on any Security of any series 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 may be paid by the Company, at its election in each case, as provided in Clause (1) or (2) below: 
 (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their
respective Predecessor Securities) are registered at the close of 

  

 34 








 
business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the
Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the
aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the
benefit of the Persons entitled to such Defaulted Interest as in this Clause provided. Thereupon the Trustee, upon consultation with the Company, shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than
15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date
and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given to each Holder of Securities of such series in the manner set forth in
Section 106, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in
whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2). 
 (2) The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent
with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this Clause,
such manner of payment shall be deemed practicable by the Trustee. 
 Subject to the foregoing provisions of this Section and
Section 305, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such
other Security. 
 Section 308. Persons Deemed Owners.  
 Prior to due presentment of a Security for registration of transfer, the Company, any Guarantor, the Trustee and any agent of the Company, a Guarantor or the Trustee may treat the Person in whose name such Security is
registered as the owner of such Security for the purpose of receiving payment of principal of and any premium and (subject to Section 305 and Section 307) any interest on such Security and for all other purposes whatsoever, whether or not
such Security be overdue, and neither the Company, any Guarantor, the Trustee nor any agent of the Company, a Guarantor or the Trustee shall be affected by notice to the contrary. 
 Section 309. Cancellation.  
 All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company or any Guarantor may at any time deliver
to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company or such Guarantor may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to
the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not issued and sold, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or
in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of by the Trustee in accordance with its customary procedures.

 Section 310. Computation of Interest.  
 Except as otherwise specified as contemplated by Section 301 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months. 
  

 35

the Trustee may determine, to the Persons entitled thereto, of the principal and any premium and interest for whose payment such money has been deposited with the Trustee. 
  

 36

 “Event of Default”, wherever used herein with respect to Securities of any series, means any one of the following events (whatever the reason
for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

 (1) default in the payment of any interest upon any Security of that series when it becomes due and payable, and

Business Days; or 
 (3) default in the deposit of any sinking fund payment, when and as due by the terms of a Security of
that series and continuance of such default for a period of 30 days or, if longer, beyond any period of grace provided with respect thereto; or

or warranty of the Company or any Guarantor in this Indenture (other than a covenant or warranty a default in whose performance or whose breach is elsewhere in this Section specifically dealt with or which has expressly been included in this
Indenture solely for the benefit of series of Securities other than that series), the Securities of that series or, as the case may require, any Guarantee, and such default or breach remains unremedied or unsatisfied for 60 days after there has been
given, by registered or certified mail, to the Company and the Guarantors by the Trustee or to the Company, the Guarantors and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Securities of that series a written
notice specifying such default and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; or 
 (5) a default under any bond, debenture, note or other evidence of indebtedness for money borrowed by the Company or any Guarantor (including a default with respect to Securities of any series other than that series)
having an outstanding aggregate principal amount of at least US$100,000,000 (or its equivalent in other currencies), or under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any
indebtedness for money borrowed by the Company (including this Indenture) or the Guarantor having an outstanding aggregate principal amount of at least US$100,000,000 (or its equivalent in other currencies), whether such indebtedness now exists or
shall hereafter be created, which default shall have resulted in such indebtedness becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable, without such acceleration having been rescinded
or annulled within a period of 10 days after there shall have been given, by registered or certified mail, to the Company and the Guarantors by the Trustee or to the Company, the Guarantors and the Trustee by the Holders of at least 25% in principal
amount of the Outstanding Securities of that series a written notice specifying such default and requiring the Company or any Guarantor, as the case may be, to cause such acceleration to be rescinded or annulled and stating that such notice is a
“Notice of Default” hereunder; provided, however, that, subject to the provisions of Sections 601 and 602, the Trustee shall not be deemed to have knowledge of such default unless either (A) a Responsible Officer of the
Trustee shall have actual knowledge of such default or (B) the Trustee shall have received written notice thereof from the Company, from the Guarantors, from any Holder, from the holder of any such indebtedness or from the trustee under any
such mortgage, indenture or other instrument; or 
  

 37 








 (6) an order is made or any effective resolution shall be passed for the winding up of
the Company or any Guarantor; or 
 (7) the Company or any Guarantor stops payment of its debts generally; or 
 (8) the Company or any Guarantor enters into or makes any arrangement with its creditors generally including entering into some form of
moratorium with its creditors generally; or 
 (9) a court having jurisdiction in the premises enters a decree or order for
relief in respect of the Company or any Guarantor in an involuntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or there is appointed in Australia or the United Kingdom a receiver, administrator,
trustee or similar officer over the whole or substantially the whole of the assets of the Company or any Guarantor, as the case may be; or 
 (10) the Company, or any Guarantor is declared insolvent by a competent judicial authority or shall admit in writing its inability to pay its debts as they fall due; or 
 (11) the Company or any Guarantor commences a voluntary case under any applicable bankruptcy, insolvency or other similar law now or
hereafter in effect, other than a case commenced under an applicable law not pertaining to bankruptcy or insolvency for the purposes of a reorganization where the Company or any Guarantor, as the case may be, is solvent, or consent to the entry of
an order for relief in an involuntary case under any such law, or consent to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of the Company or any Guarantor over
the whole or substantially the whole of its property in Australia or the United Kingdom, as the case may be, or make any general assignment for the benefit of creditors; 
 (12) any other Event of Default provided with respect to Securities of that series. 
 Section 502. Acceleration of Maturity; Rescission and Annulment.  
 If an Event of Default with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series may declare the principal amount of all the Securities of that series and any interest accrued thereon (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal
amount of such Securities as may be specified by the terms thereof) to be due and payable immediately, by a notice in writing to the Company and the Guarantors (and to the Trustee if given by Holders), and upon any such declaration such principal
amount (or specified amount) and any interest accrued thereon shall become immediately due and payable. 
 At any time after such a
declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in
principal amount of the Outstanding Securities of that series, by written notice to the Company, the Guarantors and the Trustee, may rescind and annul such declaration and its consequences if 
 (1) the Company or any Guarantor has paid or deposited with the Trustee a sum sufficient to pay 
 (A) all overdue interest on all Securities of that series, 
 (B) the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration of
acceleration and any interest accrued thereon at the rate or rates prescribed therefor in such Securities, 
 (C) to the
extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such Securities, and 
  

 38 








 (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel; 
 and 
 (2) all Events of Default with respect to Securities of that series, other than the nonpayment of the principal of Securities of that
series which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513. 
 No such rescission
shall affect any subsequent default or impair any right consequent thereon. 
 Upon receipt by the Trustee of any declaration of
acceleration, or any rescission and annulment of any such declaration, pursuant to this Section 502 with respect to Securities of any series, a record date shall automatically and without any other action by any Person be set for the purpose of
determining the Holders of Outstanding Securities of such series entitled to join in such declaration, or rescission or annulment, as the case may be, which record date shall be the close of business on the day the Trustee receives such declaration,
or rescission and annulment, as the case may be. The Holders of Outstanding Securities of such series on such record date (or their duly appointed agents), and only such Persons, shall be entitled to join in such declaration, or rescission and
annulment, as the case may be, whether or not such Holders remain Holders after such record date; provided that, unless such declaration, or rescission and annulment, as the case may be, shall have become effective by virtue of Holders of the
requisite principal amount of Outstanding Securities of such series on such record date (or their duly appointed agents) having joined therein on or prior to the 90th day after such record date, such declaration, or rescission and annulment, as the
case may be, shall automatically and without any action by any Person be cancelled and of no further effect. Nothing in this paragraph shall prevent a Holder (or a duly appointed agent thereof) from giving, before or after the expiration of such
90-day period, a declaration of acceleration, or a rescission and annulment of any such declaration, contrary to or different from, or, after the expiration of such period, identical to, a declaration, or rescission and annulment, as the case may
be, that has been cancelled pursuant to the proviso to the preceding sentence, in which event a new record date in respect thereof shall be set pursuant to this paragraph 
 Section 503. Collection of Indebtedness and Suits for Enforcement by Trustee.  
 The Company
covenants that if 
 (1) default is made in the payment of any interest on any Security when such interest becomes due and
payable and such default continues for a period of 30 days, or 
 (2) default is made in the payment of the principal of (or
premium, if any, on) any Security at the Maturity thereof and such default continues for a period of three Business Days, 
 the Company will, upon demand of
the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal and any premium and interest and, to the extent that payment of such interest shall be legally
enforceable, interest on any overdue principal and premium and on any overdue interest, at the rate or rates prescribed therefore in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 
 If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such
appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted
herein, or to enforce any other proper remedy. 
  

 39 








 Section 504. Trustee May File Proofs of Claim.  
 In case of any judicial proceeding relative to the Company, any Guarantor or any other obligor upon the Securities, or the property of the Company, any
Guarantor or other obligor or their creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders
and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver,
assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607.

 No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided,
however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee. 
 Section 505. Trustee May Enforce Claims Without Possession of Securities.  
 All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered. 
 Section 506. Application of Money Collected.  
 Any money collected by the Trustee pursuant to
this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or any premium or interest, upon presentation of the Securities and the notation
thereon of the payment if only partially paid and upon surrender thereof if fully paid: 
 FIRST: To the payment of all amounts
due the Trustee under Section 607; 
 SECOND: To the payment of the amounts then due and unpaid for principal of and any
premium and interest on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal and
any premium and interest, respectively; and 
 THIRD: To the payment of the balance, if any, to the Company or any other Person
or Persons, including the Guarantors, legally entitled thereto. 
 Section 507. Limitation on Suits.  
 No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, the
Guarantees, the Securities or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless 
 (1)
such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series specifying such Event of Default and stating that such notice is a “Notice of Default” hereunder;

  

 40 








 (2) the Holders of not less than 25% in principal amount of the Outstanding Securities of
that series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 
 (3) such Holder or Holders have offered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in
compliance with such request; 
 (4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity
has failed to institute any such proceeding; and 
 (5) no direction inconsistent with such written request has been given to
the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series; 
 it being understood
and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to
seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders. 
 Section 508. Unconditional Right of Holders to Receive Principal, Premium and Interest.  
 Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of and any premium and (subject to Section 307) interest on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date) and to institute suit for
the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. 
 Section 509. Restoration of Rights
and Remedies.  
 If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Guarantors, the Trustee
and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 
 Section 510. Rights and Remedies Cumulative.  
 Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to
the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law
or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 
 Section 511. Delay or Omission Not Waiver.  
 No
delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence
therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 
  

 41 








 Section 512. Control by Holders.  
 The Holders of a majority in principal amount of the Outstanding Securities of any series shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series, provided that 
 (1) such direction shall not be in conflict with any rule of law or with this Indenture, and 
 (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. 
 Section 513. Waiver of Past Defaults.  
 The
Holders of not less than a majority in principal amount of the Outstanding Securities of any series may, by written notice to the Trustee, on behalf of the Holders of all the Securities of such series waive any past default hereunder with respect to
such series and its consequences, except a default 
 (1) in the payment of the principal of or any premium or interest on any
Security of such series, or 
 (2) in respect of a covenant or provision hereof which under Article Nine cannot be modified or
amended without the consent of the Holder of each Outstanding Security of such series affected. 
 Upon any such waiver, such default shall
cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

 Section 514. Undertaking for Costs.  
 In any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an
undertaking to pay the costs of such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided that neither this Section nor the Trust Indenture Act shall be
deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company or any Guarantor, in any suit instituted by the Trustee, in any suit instituted by any Holder, or group of Holders,
holding in the aggregate more than 10% in principal amount of the Outstanding Securities of any series, or in any suit instituted by any Holder for the enforcement of the payment of the principal of or any premium or interest on any Security on or
after the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on or after the Redemption Date). 
 Section 515.
Waiver of Usury, Stay or Extension Laws.  
 The Company and each Guarantor covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company and the Guarantors each (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution
of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

 ARTICLE SIX 
 THE TRUSTEE 
 Section 601. Certain Duties and Responsibilities.  
 The duties and responsibilities of the Trustee shall be as provided by the Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds
for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the
liability of or affording protection to the Trustee shall be subject to the provisions of this Section. 
 Section 602. Notice of Defaults. 

 If a default occurs hereunder with respect to Securities of any series, the Trustee shall give the Holders of Securities of such series
notice of such default as and to the extent provided by the Trust Indenture Act; provided, however, that in the case of any default of the character specified in Section 501(4) with respect to Securities of such series, no such notice to
Holders shall be given until at least 60 days after the occurrence thereof. For the purpose of this Section, the term “default” means any event which is, or after notice or lapse of time or both would become, an Event of Default with
respect to Securities of such series.

evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officer’s Certificate; 
 (4) the Trustee may consult with counsel of its selection and the advice of such counsel, confirmed in writing, or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or
omitted by it hereunder in good faith and in reliance thereon; 
 (5) the Trustee shall be under no obligation to exercise any
of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses
and liabilities which might be incurred by it in compliance with such request or direction; 
 (6) the Trustee shall not be
bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper
or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to
examine the 

  

 43 








 
books, records and premises of the Company or any Guarantor, personally or by agent or attorney provided that the Trustee shall not be entitled to
such information which the Company or any Guarantor is prevented from disclosing by law or contract; 
 (7) the Trustee shall
not be deemed to have notice of any default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the
Corporate Trust Office of the Trustee, and such notice references the Securities and this Indenture; and 
 (8) the Trustee
may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney
appointed with due care by it hereunder. 
 Section 604. Not Responsible for Recitals or Issuance of Securities.  
 The recitals contained herein and in the Securities, except the Trustee’s certificates of authentication, shall be taken as the statements of the
Company or the Guarantors, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities or the
Guarantees. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of the Securities or the proceeds thereof. 
 Section 605. May Hold Securities.  
 The Trustee, any Authenticating Agent, any Paying
Agent, any Security Registrar or any other agent of the Company or any Guarantor, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to Sections 608 and 613, may otherwise deal with the Company or any
Guarantor with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent. 
 Section 606. Money Held in Trust.  
 Money held by the Trustee in trust hereunder need not be segregated from other
funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed in writing with the Company or any Guarantor, as the case may be. 
 Section 607. Compensation and Reimbursement.  
 The Company and the Guarantors jointly and severally agree 
 (1) to pay to the Trustee from time to time such
compensation as may be agreed in writing by the Company and/or any Guarantor and the Trustee for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an
express trust); 
 (2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all
reasonable expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel) all as
may be agreed between the Trustee and the Company and the Guarantors, except any such expense, disbursement or advance as may be attributable to its negligence or bad faith; and 
 (3) to indemnify the Trustee and any director, officer, employee or agent of the Trustee for, and to hold it harmless against, any loss,
liability or expense incurred without negligence or bad faith on its part, arising 

  

 44 








 
out of or in connection with the acceptance or administration of the trust or trusts hereunder, including the costs and expenses of defending itself against
any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. 
 The obligations of the
Company and the Guarantors under this Section 607 shall survive payment of all of the Securities issued pursuant to this Indenture or the resignation or removal of the Trustee. 
 Section 608. Conflicting Interests.  
 If the Trustee has or shall acquire a conflicting interest
within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. To the extent
permitted by such Act, the Trustee shall not be deemed to have a conflicting interest by virtue of being a trustee under this Indenture with respect to Securities of more than one series. 
 Section 609. Corporate Trustee Required; Eligibility.  
 There shall at all times be one (and only one) Trustee hereunder with respect to the Securities of each series, which may be Trustee hereunder for Securities of one or more other series. Each Trustee shall be a Person that is eligible
pursuant to the Trust Indenture Act to act as such, and has a combined capital and surplus of at least $50,000,000 and has its Corporate Trust Office in the borough of Manhattan, New York City, New York or in London, United Kingdom. If any such
Person publishes reports of condition at least annually, pursuant to law or to the requirements of its supervising or examining authority, then for the purposes of this Section and to the extent permitted by the Trust Indenture Act, the combined
capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee with respect to the Securities of any series shall cease to be
eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. 
 Section 610. Resignation and Removal; Appointment of Successor.  
 No resignation or removal of the Trustee and no
appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 611. 
 The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company and the
Guarantors. If the instrument of acceptance by a successor Trustee required by Section 611 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court
of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 
 The Trustee may be
removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Company and the Guarantors. 
 If at any time: 
 (1) the
Trustee shall fail to comply with Section 608 after written request therefor by the Company or any Guarantor or by any Holder who has been a bona fide Holder of a Security for at least six months, or 
 (2) the Trustee shall cease to be eligible under Section 609 and shall fail to resign after written request therefor by the Company
or any Guarantor or by any such Holder, or 
  

 45 








 (3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or
insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 

then, in any such case, (A) the Company by a Board Resolution may remove the Trustee with respect to all Securities, or (B) subject to Section 514, any
Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and
the appointment of a successor Trustee or Trustees. 
 If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy
shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those
series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular
series) and shall comply with the applicable requirements of Section 611. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series
shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the Guarantors and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon
its acceptance of such appointment in accordance with the applicable requirements of Section 611, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the
Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 611, any Holder who has been a bona fide Holder
of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

 The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series in the manner provided in Section 106. Each notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office. 
 Section 611. Acceptance of Appointment by Successor.  
 In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute,
acknowledge and deliver to the Company, to the Guarantors and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company, the Guarantors or the successor Trustee, such retiring Trustee shall, upon
payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder. 
 In case of the appointment hereunder of a successor Trustee with respect to the Securities of one
or more (but not all) series, the Company, the Guarantors, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee
shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee
with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all 

  

 46 








 
Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions of this Indenture as shall
be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees, co-trustees of the same trust
and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the
resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of
the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company, the Guarantors or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates. 
 Upon request of any such successor Trustee, the Company and the Guarantors shall execute any and all instruments for more fully and certainly vesting in
and confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may be. 
 No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article. 
 Section 612. Merger, Conversion, Consolidation or Succession to Business.  
 Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party,
or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without
the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or
consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. 
 Section 613. Preferential Collection of Claims Against Company or Guarantors.  
 If and when the Trustee shall be or become a creditor of the Company or any Guarantor (or any other obligor upon the Securities), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the
collection of claims against the Company or any such Guarantor (or any such other obligor). 
 Section 614. Appointment of Authenticating Agent. 

 The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act
on behalf of the Trustee to authenticate Securities of such series issued upon original issue and upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 306, and Securities so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee
or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by
an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a 

  

 47 








 
corporation organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such
laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus
as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner
and with the effect specified in this Section. 
 Any corporation into which an Authenticating Agent may be merged or converted or with which
it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an
Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the
Authenticating Agent. 
 An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company.
The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any
time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give notice of such appointment
in the manner provided in Section 106 to all Holders of Securities of the series with respect to which such Authenticating Agent will serve. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested
with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

 The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section, and
the Trustee shall be entitled to be reimbursed for such payments, subject to the provision of Section 607. 
 If an appointment with
respect to one or more series is made pursuant to this Section, the Securities of such series may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following
form: 
 This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

assessments or other governmental charges, is not resident in such jurisdiction, such Guarantor or Subsidiary, as the case may be, will pay to the Holder of a Security such Additional Amounts of interest as may be necessary in order that the net
amounts paid to the Holder of such Security, after such deduction or withholding, shall not be less than the amounts specified in such Security to which such Holder is entitled, except that no Additional Amounts shall be so payable for or on account
of: 
 (a) any tax, assessment or other governmental charge which would not have been imposed but for (i) the existence
of any present or former connection between such Holder (or between a fiduciary, settlor, beneficiary, member or shareholder of, or possessor of a power over, such Holder, if such Holder is an estate, trust, partnership or corporation) and the
taxing jurisdiction or any political subdivision or territory or possession thereof or area subject to its jurisdiction, including, without limitation, such Holder (or such fiduciary, settlor, beneficiary, member, shareholder or possessor) being or
having been a citizen or resident thereof or being or having been present or engaged in trade or business therein or having or having had a permanent establishment therein or (ii) the presentation of a Security (where presentation is required)

withholding from payments of (or in respect of) principal of, premium, if any, or interest on, the Securities; 
 (d) any tax,
assessment or other governmental charge that is imposed or withheld by reason of the failure to comply by the Holder or the beneficial owner of a Security with a request of the Company or the applicable Guarantor addressed to the Holder (i) to
provide information concerning the nationality, residence or identity of the Holder or such beneficial owner or (ii) to make any declaration or other similar claim or satisfy any information or reporting requirement, which, in the case of
(i) or (ii), is required or imposed by a statute, treaty, regulation or administrative practice of the taxing jurisdiction as a precondition to exemption from all or part of such tax, assessment or other governmental charge; 
 (e) any withholding or deduction imposed on a payment to an individual which is required to be made pursuant to any European Union
Directive on the taxation of savings implementing the conclusions of ECOFIN Council meeting of November 26-27, 2000 or any law implementing or complying with, or introduced in order to conform to, such Directive;

Security who would have been able to avoid such withholding or deduction by presenting the relevant Security to another Paying Agent in a member state of the European Union; or 
 (g) any withholding or deduction required to be paid on the interest (as defined in Section 128A(IAB) of the Income Tax Assessment
Act of 1936 of Australia (the “Australian Tax Act”) and which, among other things, includes amounts in the nature of, or in substitution for, interest) payable on the debt security because the Holder of a Security is an
“associate” of the Company (as that term is defined in section 128F(9) of the Australian Tax Act); 
 (h) any
withholding or deduction for which a determination is made by the Australian Commissioner of Taxation that the withholding or deduction is payable because the Holder has participated in a scheme to avoid withholding tax provided that neither the
Company nor any Guarantor participated in or was a party to such scheme; or 
 (i) any combination of items (a), (b), (c),
(d), (e), (f), (g) or (h); 
 nor shall Additional Amounts be paid with respect to any payment of the principal of, premium, if any or any interest on
any Security to any Holder who is a fiduciary or partnership or other than the sole beneficial owner of such payment to the extent such payment would be required by the laws of the jurisdiction (or any political subdivision or taxing authority
thereof or therein) to be included in the income for tax purposes of a beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to such Additional Amounts had it
been the Holder of the Security. 
 (3) immediately after giving effect to such transaction, no Event of Default, and no event
which, after notice or lapse of time or both, would become an Event of Default, shall have occurred and be continuing; and 
 (4) such Guarantor or Subsidiary, as the case may be, shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such assumption and such supplemental indenture comply with this Article
and that all conditions precedent herein provided for relating to such transaction have been complied with. 
 Upon any such assumption, such
Guarantor or Subsidiary shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such Guarantor or Subsidiary had been named as the “Company” herein,
and the Person named as the “Company” in the first paragraph of this instrument or any successor Person which shall theretofore have become such in the manner prescribed in this Article shall be released from its liability as obligor upon
the Securities.

date of the principal of or any premium or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient 

  

 55 








 
to pay the principal and any premium and interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided
and will promptly notify the Trustee of its action or failure so to act. 
 Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, on the Business Day prior to each due date of the principal of or any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as
provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. 
 The Company will cause each Paying Agent for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the
provisions of this Section, that such Paying Agent will (1) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2) during the continuance of any default by the Company or the Guarantors (or any other
obligor upon the Securities of that series) in the making of any payment in respect of the Securities of that series or any Guarantees, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent
for payment in respect of the Securities of that series or such Guarantees. 
 The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.

 Any money deposited with the Trustee or any Paying Agent, or then held by the Company or any Guarantor, in trust for the payment of the
principal of or any premium or interest on any Security of any series and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the
Company or a Guarantor) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company and the Guarantors for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at
the expense of the Company cause to be published once, in an Authorized Newspaper, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any
unclaimed balance of such money then remaining will be repaid to the Company. 
 Section 1004. Additional Amounts.  
 All payments of, or in respect of, principal of and any premium and interest on the Securities, and all payments pursuant to any Guarantee, shall be made
without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature imposed or levied by or on behalf of the jurisdiction (or any political subdivision or taxing
authority thereof or therein) in which the Company or (as the case may be) any Guarantor is incorporated unless such taxes, duties, assessments or governmental charges are required by such jurisdiction (or any such subdivision or authority thereof
or therein) to be withheld or deducted. In that event, the Company or such Guarantor, as applicable, will pay such additional amounts of, or in respect of, principal and any premium and interest (“Additional Amounts”) as will result (after
deduction of such taxes, duties, assessments or governmental charges and any additional taxes, duties, assessments or governmental charges payable in respect of such) in the payment to each Holder of a Security of the amounts which would have been
payable in respect of such Security or any Guarantee thereof, as the case may be, had no such withholding or deduction been required, except that no Additional Amounts shall be so payable for or on account of: 
 (a) any tax, assessment or other governmental charge which would not have been imposed but for (i) the existence of any present or
former connection between such Holder (or between a fiduciary, settlor, 

  

 56 








 
beneficiary, member or shareholder of, or possessor of a power over, such Holder, if such Holder is an estate, trust, partnership or corporation) and the
taxing jurisdiction or any political subdivision or territory or possession thereof or area subject to its jurisdiction, including, without limitation, such Holder (or such fiduciary, settlor, beneficiary, member, shareholder or possessor) being or
having been a citizen or resident thereof or being or having been present or engaged in trade or business therein or having or having had a permanent establishment therein or (ii) the presentation of a Security or a Guarantee (where
presentation is required) for payment on a date more than 30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later; 
 (b) any estate, inheritance, gift, sale, transfer, personal property or similar tax, assessment or other governmental charge; 

(c) any tax, assessment, or other governmental charge which is payable otherwise than by withholding from payments of (or in respect
of) principal of, premium, if any, or interest on, the Securities or the Guarantees; 
 (d) any tax, assessment or other
governmental charge that is imposed or withheld by reason of the failure to comply by the Holder or the beneficial owner of a Security with a request of the Company or the applicable Guarantor addressed to the Holder (i) to provide information
concerning the nationality, residence or identity of the Holder or such beneficial owner or (ii) to make any declaration or other similar claim or satisfy any information or reporting requirement, which, in the case of (i) or (ii), is
required or imposed by a statute, treaty, regulation or administrative practice of the taxing jurisdiction as a precondition to exemption from all or part of such tax, assessment or other governmental charge; 
 (e) in the case of a payment made by BHP Billiton Finance (USA) Limited under a Security or by BHP Billiton Limited under its Guarantees,
any tax, assessment or other governmental charge imposed as a result of the Security or the Guarantee being presented for payment in Australia unless presentment could not have been made elsewhere; 
 (f) in the case of a payment made by BHP Billiton Plc under its Guarantees, any tax, assessment or other governmental charge imposed as a
result of the Security being presented for payment in the United Kingdom unless presentment could not have been made elsewhere; 
 (g) any withholding or deduction imposed on a payment to an individual which is required to be made pursuant to any European Union Directive on the taxation of savings implementing the conclusions of ECOFIN Council meeting of
November 26-27, 2000 or any law implementing or complying with, or introduced in order to conform to, such Directive; 
 (h) any withholding or deduction required to be made with respect to a Security or Guarantee presented for payment by or on behalf of a Holder of such Security or Guarantee who would have been able to avoid such withholding or deduction by
presenting the relevant Security or Guarantee to another Paying Agent in a member state of the European Union; or 
 (i) any
withholding or deduction required to be paid on the interest (as defined in Section 128A(IAB) of the Income Tax Assessment Act of 1936 of Australia (the “Australian Tax Act”) and which, among other things, includes amounts in the
nature of, or in substitution for, interest) payable on the debt security because the Holder of a Security is an “associate” of the Company (as that term is defined in section 128F(9) of the Australian Tax Act); 
 (j) any withholding or deduction for which a determination is made by the Australian Commissioner of Taxation that the withholding or
deduction is payable because the Holder has participated in a scheme to avoid withholding tax provided that neither the Company nor any Guarantor participated in or was a party to such scheme; or 
 (k) any combination of items (a), (b), (c), (d), (e), (f), (g), (h), (i) or (j); 
 nor shall Additional Amounts be paid with respect to any payment of the principal of, premium, if any or any interest on any Security or any Guarantee to any Holder who
is a fiduciary or partnership or other than the sole 

  

 57 








 
beneficial owner of such payment to the extent such payment would be required by the laws of the jurisdiction (or any political subdivision or taxing
authority thereof or therein) to be included in the income for tax purposes of a beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to such Additional Amounts
had it been the Holder of the Security. 
 Whenever in this Indenture there is mentioned, in any context, the payment of the principal of or
any premium or interest on, or in respect of, any Security of any series or any payments pursuant to a Guarantee thereof or the net proceeds received on the sale or exchange of any Security of any series, such mention shall be deemed to include
mention of the payment of Additional Amounts provided for in this Section to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to the provisions of this Section and express mention of the
payment of Additional Amounts (if applicable) in any provisions hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made. 
 Section 1005. Statement by Officers as to Default.  
 The Company and the Guarantors each will deliver to the Trustee, within 120 days after the end of each fiscal year of the Company or applicable Guarantor ending after the date hereof, an Officer’s Certificate, stating whether or not to
the best knowledge of the signers thereof the Company or the Guarantor, as the case may be, is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or
requirement of notice provided hereunder) and, if the Company or applicable Guarantor shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge. 
 Section 1006. Existence.  
 Subject to Article
Eight, the Company and each Guarantor will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence. 
 Section 1007. Payment of Taxes and Other Claims.  
 The Company and the Guarantors will pay or discharge or cause to be
paid or discharged, before the same shall become delinquent, (1) all taxes, assessments and governmental charges levied or imposed upon it or any of its Subsidiaries or upon its or any of its Subsidiaries’ income, profits or property, and
(2) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a lien upon its or any of its Subsidiaries’ property, provided, however, that the Company and the Guarantors shall not be required to pay
or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings. 
 Section 1008. Limitations on Liens.  
 So long as
any of the Securities of a particular series of debt securities are Outstanding, the Guarantors shall not, and the Guarantors shall not permit the Company to, create, incur, assume or suffer to exist any Liens (except for Permitted Liens) upon any
of their respective Property (whether owned as of the date of this Indenture or thereafter acquired) to secure any present or future indebtedness for borrowed money without making, or causing the Company to make, effective provision whereby all the
Securities shall be directly secured equally and ratably with such indebtedness for borrowed money, so long as such indebtedness for borrowed money shall be so secured. 
 Notwithstanding the foregoing, the Company and any Guarantor may at any time create, incur, assume or suffer to exist any Lien on their respective Property, assets or income or profit therefrom if at such time the
amount of the liability or obligation secured by such Lien, together with all liabilities or obligations secured by all such Liens existing at such time, does not exceed 10% of Net Tangible Assets. Nothing herein shall restrict the ability of
Subsidiaries of either Guarantor (other than the Company) to create, incur, assume or suffer to exist any Liens. 
  

 58 








 Section 1009. Limitation on Sales and Leasebacks.  
 So long as any of the Securities are Outstanding, the Guarantors shall not, and shall not permit the Company to, enter into any arrangement with any bank,
insurance company or other lender or investor (not including any Guarantor or the Company), or to which any such lender or investor is a party, providing for the leasing by any Guarantor or the Company for a period, including renewals, in excess of
three years of any Property which has been owned by any Guarantor or the Company for more than six months and which has been or is to be sold or transferred by any Guarantor or the Company to such lender or investor or, as a part of such
arrangement, to any Person to whom funds have been or are to be advanced by such lender or investor on the security of such Property (herein referred to as a “sale and leaseback transaction”) unless either: 
 (1) any Guarantor or the Company could create indebtedness secured by a Lien pursuant to Section 1008 on the Property to be leased
back in an amount equal to the indebtedness attributable to such sale and leaseback transaction without equally and ratably securing the Securities of any series; or 
 (2) any Guarantor or the Company, within one year after the sale or transfer will have been made by any Guarantor or the Company, applies
an amount equal to the greater of (i) the net proceeds of the sale of the Property sold and leased back pursuant to such arrangement or (ii) the fair market value of the Property so sold and leased back at the time of entering into such
arrangement (as determined by any two executive officers and/or Directors of such Guarantor) to (A) the retirement of indebtedness for money borrowed, incurred or assumed by such Guarantor or the Company which by its terms matures at, or is
extendible or renewable at the option of the obligor to, a date more than twelve months after the date of incurring, assuming or guaranteeing such indebtedness or (B) investment in any Property of such Guarantor or the Company. 
 Nothing herein shall restrict the ability of any Subsidiaries of any Guarantor (other than the Company) to enter into sale and leaseback transactions.

 Section 1010. Waiver of Certain Covenants.  
 Except as otherwise specified as contemplated by Section 301 for Securities of such series, the Company and the Guarantors may, with respect to the Securities of any series, omit in any particular instance to
comply with any term, provision or condition set forth in any covenant provided pursuant to Section 301(19), 901(2) or 901(7) for the benefit of the Holders of such series or in Article Eight or any of Sections 1004, 1006, 1007, 1008 or 1009 if
before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with
such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the
Guarantors and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 301 for such Securities) in accordance with this Article.

 Section 1102. Election to Redeem; Notice to Trustee.  
 The election of the Company to redeem any Securities shall be evidenced by a Board Resolution or in another manner specified as contemplated by
Section 301 for such Securities. In case of any redemption at the election of the Company, the Company shall, at least 60 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee),
notify the Trustee of such Redemption Date, of the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed. In the case of any redemption of Securities prior to the expiration of
any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officer’s Certificate evidencing compliance with such restriction. 
 Section 1103. Selection by Trustee of Securities to Be Redeemed.  
 If less than all the Securities of any series are to be redeemed (unless all the Securities of such series and of a specified tenor are to be redeemed or unless such redemption affects only a single Security), the
particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of a portion of the principal amount of any Security of such series, provided that the unredeemed portion of the principal amount of any Security shall be in an
authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. If less than all the Securities of such series and of a specified tenor are to be redeemed (unless such redemption affects only a single
Security), the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series and specified tenor not previously called for redemption in
accordance with the preceding sentence. 
 The Trustee shall promptly notify the Company in writing of the Securities selected for redemption
as aforesaid and, in case of any Securities selected for partial redemption as aforesaid, the principal amount thereof to be redeemed. 
 The
provisions of the two preceding paragraphs shall not apply with respect to any redemption affecting only a single Security, whether such Security is to be redeemed in whole or in part. In the case of any such redemption in part, the unredeemed
portion of the principal amount of the Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. 
 For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the
case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed. 
 Section 1104. Notice of Redemption.  
 Notice of redemption shall be given by first-class mail, postage prepaid, mailed
not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities (or, in the case of a Global Security, the Depositary or its designated nominee) to be redeemed, at the Holder’s address appearing in the Security
Register. 
 All notices of redemption shall identify the Securities to be redeemed (indicating CUSIP Number, if any) and shall state:

 (1) the Redemption Date, 
 (2) the Redemption Price plus accrued interest, if any, 
 (3) if less than all the
Outstanding Securities of any series consisting of more than a single Security are to be redeemed, the identification (and, in the case of partial redemption of any such Securities, the principal 

  

 60 








 
amounts) of the particular Securities to be redeemed and, if less than all the Outstanding Securities of any series consisting of a single Security are to be
redeemed, the principal amount of the particular Security to be redeemed, 
 (4) that on the Redemption Date the Redemption
Price, plus accrued interest, if any, will become due and payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date, 
 (5) the place or places where each such Security is to be surrendered for payment of the Redemption Price, plus accrued interest, if any,
and 
 (6) that the redemption is for a sinking fund, if such is the case. 
 Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s request, by the
Trustee in the name and at the expense of the Company and shall be irrevocable. 
 Section 1105. Deposit of Redemption Price.  
 Prior to 10:00 a.m., New York City time, on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company or
any Guarantor is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date)
accrued interest on, all the Securities which are to be redeemed on that date. 
 Section 1106. Securities Payable on Redemption Date. 

 Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable
at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security
for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date; provided, however, that, unless otherwise specified as contemplated by
Section 301, installments of interest on Securities whose Stated Maturity is on or prior to the Redemption Date will be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of
business on the relevant Record Dates according to their terms and the provisions of Section 307. 
 If any Security called for
redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security. 
 Section 1107. Securities Redeemed in Part.  
 Any
Security which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the
Trustee duly executed by, the Holder thereof or his or her attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Security without service charge,
a new Security or Securities of the same series and of like tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so
surrendered. 
 Section 1108. Optional Redemption Due to Changes in Tax Treatment.  
 Each series of Securities may be redeemed at the option of the Company or any Guarantor in whole but not in part at any time (except in the case of
Securities that have a variable rate of interest, which may be redeemed 

  

 61 








 
on any Interest Payment Date) at a redemption price equal to the principal amount thereof plus accrued interest to the date fixed for redemption (except in
the case of Outstanding Original Issue Discount Securities which may be redeemed at the Redemption Price specified by the terms of such series of Securities) if, as a result of any change in or amendment to the laws or any regulations or rulings
promulgated thereunder of the jurisdiction (or of any political subdivision or taxing authority thereof or therein) in which the Company or any Guarantor is incorporated or any change in the official application or interpretation of such laws,
regulations or rulings, or any change in the official application or interpretation of, or any execution of or amendment to, any treaty or treaties affecting taxation to which such jurisdiction (or such political subdivision or taxing authority) is
a party, which change, execution or amendment becomes effective on or after the date specified for such series pursuant to Section 301(7), (i) the Company or the relevant Guarantor (or such Subsidiary) is or would be required to pay
Additional Amounts with respect to the Securities or the Guarantees, as the case may be, as described in Section 205 or (ii) the relevant Guarantor or any Subsidiary of any Guarantor is or would be required to deduct or withhold tax on any
payment to the Company (or such Subsidiary) to enable the Company (or such Subsidiary) to make any payment of principal, premium, if any, or interest and, in each case, the payment of such Additional Amounts in the case of (i) above or such
deductions or withholding in the case of (ii) above cannot be avoided by the use of any reasonable measures available to the Company, any Guarantor or the Subsidiary. Prior to the giving of notice of redemption of such Securities pursuant to
this Indenture, the Company or the relevant Guarantor (or such Subsidiary) will deliver to the Trustee an Officer’s Certificate, stating that the Company or the relevant Guarantor (or such Subsidiary) is entitled to effect such redemption and
setting forth in reasonable detail a statement of circumstances showing that the conditions precedent to the right of the Company or the relevant Guarantor (or such Subsidiary) to redeem such Securities pursuant to this Section has been satisfied.

 Further, if pursuant to Section 801(3) of this Indenture, a Person has been or would be required to pay any Additional Amounts as
therein provided, each series of Securities may be redeemed at the option of such Person in whole, but not in part, at any time (except in the case of Securities that have a variable rate of interest, which may be redeemed on any Interest Payment
Date), at a redemption price equal to the principal amount thereof plus accrued interest to the date fixed for redemption (except in the case of Outstanding Original Issue Discount Securities which may be redeemed at the Redemption Price specified
by the terms of such series of Securities). Prior to the giving of notice of redemption of such Securities pursuant to this Indenture, such Person will deliver to the Trustee an Officer’s Certificate, stating that such Person is entitled to
effect such redemption and setting forth in reasonable detail a statement of circumstances showing that the conditions precedent to the right of such Person to redeem such Securities pursuant to this Section has been satisfied.

 Upon the exercise by the Company or any Guarantor of its option (if any) to have this Section applied to any Securities or any series of Securities, as
the case may be, the Company and the Guarantors shall be deemed to have been discharged from all their respective obligations with respect to such Securities as provided in this Section on and after the date the conditions set forth in

Securities and to have satisfied all their other obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company and the Guarantors, shall execute proper instruments
prepared by the Company acknowledging the same), subject to the following which shall survive until otherwise terminated or discharged hereunder: (1) the rights of Holders of such Securities to receive, solely from the trust fund described in

 Upon
exercise by the Company or any Guarantor of its option (if any) to have this Section applied to any Securities or any series of Securities, as the case may be, (1) the Company and the Guarantors shall be released from their obligations under

case with respect to such Securities as provided in this Section on and after the date the conditions set forth in Section 1304 are satisfied (hereinafter called “Covenant Defeasance”). For this purpose, such Covenant Defeasance means

of Section 501(4)), whether directly or indirectly by reason of any reference elsewhere herein to any such Section or by reason of any reference in any such Section to any other provision herein or in any other document, but the remainder of
this Indenture and such Securities shall be unaffected thereby.

pledged as security for, and dedicated solely to, the benefits of the Holders of such Securities, (A) money in an amount, or (B) U.S. Government Obligations which through the scheduled payment of principal and interest in respect thereof
in accordance with their terms will provide, not later than one day before the due date of any payment, money in an amount, or (C) a combination thereof, in each case sufficient, in the opinion of a firm of independent public accountants
nationally recognized in the United States obtained at the expense of the Company or any Guarantor expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or any such
other qualifying trustee) to pay and discharge, (i) the principal of and any premium and interest on such Securities on the respective Stated Maturities and (ii) any mandatory sinking fund payments or analogous payments applicable to such
Outstanding Securities on the day on which such payments are due and payable, in accordance with the terms of this Indenture and such Securities. As used herein, “U.S. Government Obligation” means (x) any security which is (i) a
direct obligation of the United States of America for the payment of which the full faith and credit of the United States of America is pledged or (ii) an obligation of a Person controlled or supervised by and acting as an agency or
instrumentality of the United States of America the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in either case (i) or (ii), is not callable or redeemable at the
option of the issuer thereof, and (y) any depositary receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act) or trust company as custodian with respect to any U.S. Government Obligation which is specified in Clause
(x) above and held by such bank for the account of the holder of such depositary receipt, or with respect to any specific payment of principal of or interest on any U.S. Government Obligation which is so specified and held, provided that
(except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depositary

receipt from any amount received by the custodian in respect of the U.S. Government Obligation or the specific payment of principal or interest evidenced by
such depositary receipt. 
 (2) In the event of an election to have Section 1302 apply to any Securities or any series of
Securities, as the case may be, the Company or a Guarantor shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Company or a Guarantor has received from, or there has been published by, the Internal Revenue Service a
ruling or (B) since the date of this instrument, there has been a change in the applicable Federal income tax law, in either case (A) or (B) to the effect that, and based thereon such opinion shall confirm that, the Holders of such
Securities will not recognize gain or loss for U.S. Federal income tax purposes as a result of the deposit, Defeasance and discharge to be effected with respect to such Securities and will be subject to U.S. Federal income tax on the same amount, in
the same manner and at the same times as would be the case if such deposit, Defeasance and discharge were not to occur. 
 (3)
In the event of an election to have Section 1303 apply to any Securities or any series of Securities, as the case may be, the Company or a Guarantor shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of
such Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit and Covenant Defeasance to be effected with respect to such Securities and will be subject to Federal income tax on the same amount, in the
same manner and at the same times as would be the case if such deposit and Covenant Defeasance were not to occur. 
 (4) The
Company or any Guarantor shall have delivered to the Trustee an Opinion of Counsel to the effect that such deposit, Defeasance and discharge, or such deposit and Covenant Defeasance, as the case may be, will not cause the Holders of such Securities
to recognize income, gain or loss for Australian or United Kingdom tax purposes and to the effect that all payments out of the trust fund will be made free and exempt from any and all withholding or other income taxes of whatever nature of Australia
or the United Kingdom or any political subdivision or taxing authority thereof or therein. 
 (5) The Company or a Guarantor
shall have delivered to the Trustee an Officer’s Certificate to the effect that neither such Securities nor any other Securities of the same series, if then listed on any securities exchange, will be delisted as a result of such deposit.

 (6) No event which is, or after notice or lapse of time or both would become, an Event of Default with respect to such
Securities or any other Securities shall have occurred and be continuing at the time of such deposit or, with regard to any such event specified in Sections 501(6) through 501(11), at any time on or prior to the 90th day after the date of such
deposit (it being understood that this condition shall not be deemed satisfied until after such 90th day). 
 (7) Such
Defeasance or Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act). 
 (8) Such Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any other
agreement or instrument to which the Company or any Guarantor is a party or by which it is bound. 
 (9) Such Defeasance or
Covenant Defeasance shall not result in the trust arising from such deposit constituting an investment company within the meaning of the Investment Company Act unless such trust shall be registered under such Act or exempt from registration
thereunder. 
 (10) The Company or a Guarantor shall have delivered to the Trustee an Officer’s Certificate and an
Opinion of Counsel, each stating that all conditions precedent with respect to such Defeasance or Covenant Defeasance have been complied with.

 Section 1305. Deposited Money and U.S. Government Obligations to Be Held in Trust; Miscellaneous Provisions. 

 Subject to the provisions of the last paragraph of Section 1003, all money and U.S. Government Obligations (including the proceeds
thereof) deposited with the Trustee or other qualifying trustee (solely for purposes of this Section and Section 1306, the Trustee and any such other trustee are referred to collectively as the “Trustee”) pursuant to Section 1304
in respect of any Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any such Paying Agent (including the Company or any
Guarantor acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities, of all sums due and to become due thereon in respect of principal and any premium and interest, but money so held in trust need not be
segregated from other funds except to the extent required by law. 
 The Company or any Guarantor shall pay and indemnify the Trustee against
any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 1304 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law
is for the account of the Holders of Outstanding Securities. 
 Anything in this Article to the contrary notwithstanding, the Trustee shall
deliver or pay to the Company or any Guarantor from time to time upon Company Request any money or U.S. Government Obligations held by it as provided in Section 1304 with respect to any Securities which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect the Defeasance or Covenant
Defeasance, as the case may be, with respect to such Securities. 
 Section 1306. Reinstatement.  
 If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article with respect to any Securities by reason of any order or
judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under this Indenture and such Securities from which the Company and the Guarantors have been discharged or
released pursuant to Section 1302 or 1303 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Securities, until such time as the Trustee or Paying Agent is permitted to apply all money
held in trust pursuant to Section 1305 with respect to such Securities in accordance with this Article; provided, however, that if the Company or any Guarantor makes any payment of principal of or any premium or interest on any such
Security following such reinstatement of its obligations, the Company and the Guarantors shall be subrogated to the rights (if any) of the Holders of such Securities to receive such payment from the money so held in trust. 
 This instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together
constitute but one and the same instrument.
