SECTION 104. Acts of Holders; Record Dates.

provided or permitted by this Indenture to be given, made or taken by Holders may be embodied in
and evidenced by one or more instruments of substantially similar tenor signed by such Holders in
person or by an agent duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments are delivered to
the Trustee and, where it is hereby expressly required, to the Company and to each of the
Guarantors. Such instrument or instruments (and the action embodied therein and evidenced thereby)
are herein sometimes referred to as the “Act” of the Holders signing such instrument or
instruments. Proof of execution of any such instrument or of a writing appointing any such agent
shall be sufficient for any purpose of this Indenture and (subject to Section 601) conclusive in
favor of the Trustee and the Company and the Guarantors, if made in the manner provided in 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 to him the execution thereof. Where such execution
is by

9

 

a signer acting in a capacity other than his individual capacity, such certificate or
affidavit shall also constitute sufficient proof of his authority. The fact and date of the
execution of any such instrument or writing, or the authority of the Person executing the same, may
also be proved in any other manner which the Trustee deems sufficient.

          The ownership of Securities shall be proved by the Security Register.

          Any request, demand, authorization, direction, notice, consent, waiver or other Act of the
Holder of any Security shall bind every future Holder of the same Security and the Holder of every
Security issued upon the registration of transfer thereof or in exchange therefor or in lieu
thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company
or any Guarantor in reliance thereon, whether or not notation of such action is made upon such
Security.

          The Company and the Guarantors may set any day as a record date for the purpose of determining
the Holders of Outstanding Securities of any series entitled to give, make or take any request,
demand, authorization, direction, notice, consent, waiver or other action provided or permitted by
this Indenture to be given, made or taken by Holders of Securities of such series, provided that
the Company and the Guarantors may not set a record date for, and the provisions of this paragraph
shall not apply with respect to, the giving 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.

          The Trustee may set any day as a record date for the purpose of determining the Holders of
Outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of
Default, (ii) any declaration of acceleration referred to in Section 502, (iii) any request to
institute proceedings referred to in 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

10

 

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 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 180th 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.

          Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or
other document provided or permitted by this Indenture to be made upon, given or furnished to, or
filed with,

          (1) the Trustee by any Holder or by the Company or any of the Guarantors shall be sufficient
for every purpose hereunder if made, given, furnished or filed or mailed first-class postage
prepaid in writing to or with the Trustee at its Corporate Trust Office, Attention: Institutional
Trust Services, or

          (2) the Company or any of the Guarantors by the Trustee or by any Holder shall be sufficient
for every purpose hereunder (unless otherwise 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 his 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

11

 

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.

          If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture
Act which is required under such Act to be a part of and govern this Indenture, the latter
provision shall control. If any 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.

SECTION 109. Effect of Headings and Table of Contents.

          The Article and Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

SECTION 110. Successors and Assigns.

          All covenants and agreements in this Indenture by the Company or a Guarantor shall bind its
successors and assigns, whether so expressed or not.

SECTION 111. Separability Clause.

          In case any provision in this Indenture or in the Securities or the Guarantees shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

SECTION 112. Benefits of Indenture.

          Nothing in this Indenture or in the Securities or the Guarantees, express or implied, shall
give to any Person, other than the parties hereto and their successors hereunder and the Holders,
any benefit or any legal or equitable right, remedy or claim under this Indenture.

          This Indenture, the Securities and the Guarantees shall be governed by and construed in
accordance with the law of the State of New York without regard to principles of conflicts of law.

SECTION 114. Saturdays, Sundays and Legal Holidays.

          In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any
Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other
provision of this Indenture or of the Securities (other than a provision of any Security which
specifically 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 Date or Stated Maturity, as the case may be.

SECTION 115. Appointment of Agent for Service.

          By the execution and delivery of this Indenture, the Company and each Guarantor hereby
severally appoints Rio Tinto Services Inc. as its agent upon which process may be served in any
legal action or proceeding which may be instituted in any Federal or State court in the Borough of
Manhattan, New York City, arising out of or relating to the Securities, the Guarantees or this
Indenture, but for that purpose only, and waives any objection which it may now or hereafter have
to the laying of venue of any such proceeding, and irrevocably submits to the non-exclusive
jurisdiction of such courts in any such proceeding. Service of process upon such agent at the
office of such agent at 100 Quentin Roosevelt Blvd., Suite 503, Garden City, NY 11530, and written
notice of said service to the Company and each of the Guarantors by the Person serving the same

upon the Company and the Guarantors, respectively, in any such legal action or proceeding, and the
Company and the Guarantors, respectively, hereby submit to the nonexclusive jurisdiction of any
such court in which any such legal action or proceeding is so instituted. Such appointment shall be
irrevocable so long as the Holders of Securities shall have any rights pursuant to the terms
thereof or of this Indenture until the appointment of a successor by the Company or any of the
Guarantors, as the case may be, with the consent of the Trustee and such 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 designation and appointment of such agent or successor until this
Indenture has been satisfied, discharged or defeased in accordance with Article Four or Article
Thirteen hereof.

amount equal to the applicable Redemption Price multiplied by a fraction the numerator of which is
the number of days from but not including the preceding                 to and including the
Redemption Date multiplied by the difference between the Redemption Price applicable during the 12
months beginning on the               following the Redemption Date (or, in the case of a

the face hereof or] in the Guarantee endorsed hereon) resulting from the payment of such Redemption
Price.]]

than 60 days period to the dated fixed for redemption, all as provided in the Indenture.

          [If the Security is subject to redemption of any kind, insert — In the event of redemption of
this Security in part only, a new Security or Securities of this series and of like tenor for the
unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation
hereof.]

          [If applicable, insert — The Indenture contains provisions for defeasance at any time of [the
entire indebtedness of this Security ] [or] [certain restrictive covenants and Events of Default

in the Indenture.]

          [If the Security is not an Original Issue Discount Security, insert — If an Event of Default
with respect to Securities of this series shall occur and be continuing, the principal of the
Securities of this series may be declared due and payable in the manner and with the effect
provided in the Indenture. ]

          [If the Security is an Original Issue Discount Security, insert — If an Event of Default with
respect to Securities of this series shall occur and be continuing, an amount of principal of the
Securities of this series may be declared due and payable in the manner and with the effect
provided in the Indenture. Such amount shall be equal to— insert formula for determining the
amount. Upon payment (i) of the amount of principal so declared due and payable and (ii) of
interest on any overdue principal, premium and interest (in each case to the extent that the
payment of such interest shall be legally enforceable), all of the Company’s obligations in
respect of the payment of the principal of and premium and interest, if any, on the Securities of
this series shall terminate.]

          The Indenture permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Company and the Guarantors and the rights of
the Holders of the Securities of each series to be affected under the Indenture at any time by the
Company, the Guarantors and the Trustee with the consent of the Holders of a majority in principal
amount of the Securities at the time Outstanding of each series to be affected. The Indenture also
contains provisions permitting the Holders of specified percentages in principal

amount of the Securities of each series at the time Outstanding, on behalf of the Holders of
all Securities of such series, to waive compliance by the Company or the Guarantors with certain
provisions of the Indenture and certain past defaults under the Indenture and their consequences.
Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such
Holder and upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation
of such consent or waiver is made upon this Security.

          As provided in and subject to the provisions of the Indenture, no Holder of any Security of
this series will have the right to institute any proceeding with respect to the Indenture, the
Guarantee endorsed hereon, this Security or for the appointment of a receiver or trustee or for any
other remedy thereunder, unless such Holder shall have previously given the Trustee written notice
of a continuing Event of Default with respect to the Securities of this series, the Holders of not
less than 25% in principal amount of the Securities of this series at the time Outstanding shall
have made written request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have
received from the Holders of a majority in principal amount of Securities of this series at the
time Outstanding a direction inconsistent with such request, and shall have failed to 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

principal of and any premium and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing,
and thereupon one or more new Securities of this series and of like tenor, of authorized
denominations and for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

          The Securities of this series are issuable only in registered form without coupons in

authorized denomination, as requested by the Holder surrendering the same.

          No service charge shall be made for any such registration of transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

          Prior to due presentment of this Security for registration of transfer or exchange, the

GUARANTEE

          Rio Tinto plc, a public limited company incorporated under the laws of England, having its

to herein as a “Guarantor”, which term includes any successor Person under the

21

 

Indenture referred to in the Security upon which this Guarantee is endorsed, and together, the
“Guarantors”), for value received hereby unconditionally guarantee to the Holder of the Security
upon which this Guarantee is endorsed and to the Trustee on behalf of each such Holder the due and
punctual payment of the principal of, premium, if any, and interest on such Security (including any
additional amounts payable pursuant to Section 1004 of the Indenture in respect thereof) and the
due and punctual payment of the sinking fund or analogous payments referred to therein, if any,
when and as the same shall become due and payable (subject to any period of grace provided with
respect thereto), whether at the Stated Maturity, by declaration of acceleration, call for
redemption or otherwise, according to the terms thereof and of the Indenture referred to therein.
In the case of the failure of Rio Tinto Finance (USA) Limited, a corporation organized under the

successor Person under such Indenture), punctually to make any such payment of principal, premium,
if any, or interest or any sinking fund or analogous payment, the Guarantors hereby, jointly and
severally, agree to cause any such payment to be made punctually when and as the same shall become
due and payable, whether at the Stated Maturity or by declaration of acceleration, call for
redemption or otherwise, and as if such payment were made by the Company. The obligations of the
Guarantors under this Guarantee shall be joint and several.

          [If applicable, insert — Each of the Guarantors hereby further agrees, subject to the
limitations and exceptions set forth below, that if any deduction or withholding for any present or
future taxes, assessments or other governmental charges of the jurisdiction (or any political
subdivision or taxing authority thereof or therein) in which such Guarantor is incorporated shall
at any time be required by such jurisdiction (or any such political subdivision or taxing
authority) in respect of any amount to be paid by such Guarantor under this Guarantee, then such
Guarantor will pay to the Holder of a Security such additional amounts as may be necessary in order
that the net amounts paid to the Holder of such Security who, with respect to any such tax,
assessment, or other governmental charge, is not resident in such jurisdiction, after such
deduction or withholding, shall be not less than the amounts specified in such Security to which
such Holder is entitled; provided however, that such Guarantor shall not be required to
make any payment of additional amounts (i) if the Holder is a United States Person, for or on
account of any such tax, assessment or other governmental charge imposed by the United States or
any political subdivisions or taxing authority thereof or therein, (ii) 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) 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;

22

 

     (c) any tax, assessment, or other governmental charge which is payable otherwise than
by withholding form 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 Clause (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 Rio Tinto plc under the 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;

     (f) 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;

     (g) any withholding or deduction required to be made with respect to a Security
presented for payment by or on behalf of a Holder of such 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

     (h) 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, amount 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);

     (i) 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

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

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.]

          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,

23

 

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.

          Executed and dated the date on the face hereof.

27

 

          (18) any addition to or change in the Events of Default which applies to any Securities of the

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 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
Vice Chairman of the Board, its President 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

28

 

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.

          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.

29

 

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 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

30

 

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 his 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 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.

          (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.

31

 

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 therefor 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 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 business on a Special Record Date for the payment of such

32

 

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

33

 

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.

SECTION 311. CUSIP Numbers.

          The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and,
if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders;
provided that any such notice may state that no representation is made as to the correctness of
such numbers either as printed on the Securities or as contained in any notice of a redemption and
that reliance may be placed only on the other identification numbers printed on the Securities, and
any such redemption shall not be affected by any defect in or omission of such numbers.

ARTICLE FOUR

SATISFACTION AND DISCHARGE

for and the obligation of the Company or any Guarantor to pay any additional amounts as
contemplated by Section 1004), and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging satisfaction and discharge of this Indenture, when

          (1) either

     (A) all Securities theretofore authenticated and delivered (other than (i) Securities
which have been destroyed, lost or stolen and which have been replaced or paid as provided
in Section 306 and (ii) Securities for whose payment money has theretofore been deposited in
trust or segregated and held in trust by the Company or any Guarantor and thereafter repaid

have been delivered to the Trustee for cancellation; or

     (B) all such Securities not theretofore delivered to the Trustee for cancellation

34

 

(i) have become due and payable, or

(ii) will become due and payable at their Stated Maturity within one year, or

be deposited with the Trustee as trust funds in trust for the purpose money in an amount
sufficient to pay and discharge the entire indebtedness on such Securities not theretofore
delivered to the Trustee for cancellation, for principal and any premium and interest to the
date of such deposit (in the case of Securities which have become due and payable) or to the
Stated Maturity or Redemption Date, as the case may be;

(2) the Company or any Guarantor has paid or caused to be paid all other sums payable

Trustee pursuant to Section 401 shall be held in trust and applied by it, in accordance with the
provisions of the Securities and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company or any Guarantor acting as its own Paying Agent) as 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.

ARTICLE FIVE

other than that series), and continuance of such default or breach for a period of 90 days
after there has been given, by registered or certified mail, by the Trustee or to the
Company, the Guarantors and the Trustee by the Holders of at least 25% in principal amount

(6) the commencement by the Company or any Guarantor of a voluntary case or proceeding under
any applicable Australian or English bankruptcy, insolvency, reorganization or other similar

such reconstruction occurred; or

(7) any Borrowing, other than the Securities or Guarantees, of the Company or the Guarantors

of default by the Company or, as the case may be, any Guarantor in accordance with the terms
relating to such Borrowing and steps being taken to obtain repayment thereof; or, after any
period of grace originally applicable, in relation to any Borrowings having an outstanding
principal amount of at least the specified amount (i) the Company or any Guarantor
defaulting in the payment, when due and called upon, of any Borrowing of a principal amount
of at least the specified amount or in the honoring of any guarantee or indemnity in respect
of any Borrowing of a principal amount of at least the specified amount of others and steps
being taken to enforce the same or (ii) any mortgage, pledge or other charge granted by the
Company or any Guarantor becoming enforceable and steps being taken to enforce the same; or

(8) 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 (other than an Event of Default specified in Section 501(5) or 501(6))
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. If an Event of Default specified in Section 501(5) or 501 (6) with
respect to Securities of any series at the time Outstanding occurs, 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) shall automatically, and without any declaration or other
action on the part of the Trustee or any Holder, 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 the Guarantors have 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,

37

 

     (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

     (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
non-payment 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.

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 seven 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 therefor 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.

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

38

 

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;

     (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;

39

 

     (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.

40

 

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.

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

41

 

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.

SECTION 603. Certain Rights of Trustee.

     Subject to the provisions of Section 601:

     (1) the Trustee may rely and shall be protected in acting or refraining from acting upon
any resolution, certificate, statement, instrument, opinion, report, notice, request,
direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper
or

42

 

document believed by it to be genuine and to have been signed or presented by the proper
party or parties;

     (2) any request or direction of the Company or any Guarantor mentioned herein shall be
sufficiently evidenced by a Company Request or Company Order, and any resolution of the
Board of Directors of the Company or any Guarantor shall be sufficiently evidenced by a
Board Resolution;

     (3) whenever in the administration of this Indenture the Trustee shall deem it desirable
that a matter be proved or established prior to taking, suffering or omitting any action
hereunder, the Trustee (unless other 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 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 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;

     (8) the Trustee shall not be liable for any action taken, suffered, or omitted to be taken
by it in good faith and reasonably believed by it to be authorized or within the discretion or
rights or powers conferred upon it by this Indenture, provided, that, subject to Section 601
and this Section 603, no provision of this Indenture shall be construed to relieve the Trustee
for liability for its own negligent action, its own negligent failure to act or its own wilful
misconduct; and

     (9) 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 such Default or Event of Default is received by the Trustee at the Corporate Trust
Office of the Trustee, and such notice references the Securities.

43

 

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 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 for, and to hold it harmless against, any and all loss,
liability, damage, claim or expense arising 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, liability or damage in connection with the exercise or performance of
any of its powers or duties hereunder, except to the extent that such loss, liability, damage,
claim or expense may be attributable to its negligence or bad faith.

     As security for the performance of the obligations of the Company and the Guarantors under
this Section 607, the Trustee shall have a lien prior to the Outstanding Securities of any series

44

 

upon all property and funds held or collected by the Trustee as such, except property or funds held
in trust for the benefits of the Holders of any such Outstanding Securities. “Trustee” for purposes
hereof includes any predecessor trustee, but the negligence or bad faith of any trustee shall not
affect the rights of any other trustee hereunder.

     When the Trustee incurs expenses or renders services in connection with an Event of Default
specified in Section 501(5) or Section 501(6), the expenses (including the reasonable charges and
expenses of its counsel) and the compensation for the services are intended to constitute expenses
of administration under any applicable federal or state bankruptcy, insolvency or other similar
law.

     The provisions of this Section shall survive the resignation or removal of the Trustee and the
termination of this Indenture.

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. 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.

45

 

          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 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 delivery of such Act of the Holders, 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.

     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

     (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.

46

 

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
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.

47

 

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 Guarantor.

          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 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,

48

 

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 Company agrees to pay to each Authenticating Agent from time to time reasonable
compensation for its services under this Section.

          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.

	 	 	 	 	 	 	 
	 	 	THE CHASE MANHATTAN BANK,	 	 
	 

	 	 	 	As Trustee	 	 
	 
	 	 	 	 	 	 
	 

	 	By	 	 	 	 
	 

	 	 	 	 

As Authenticating Agent
	 	 
	 
	 	 	 	 	 	 
	 

	 	By	 	 	 	 
	 

	 	 	 	 

Authorized Officer
	 	 

          If all of the Securities of a series may not be originally issued at one time, and if the
Trustee does not have an office capable of authenticating Securities upon original issuance located
in a Place of Payment where the Company wishes to have Securities of such series authenticated upon
original issuance, the Trustee, if so requested by the Company in writing (which writing need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel), shall appoint in
accordance with this Section an Authenticating Agent having an office in a Place of Payment
designated by the Company with respect of such series of Securities.

     (1) semi-annually, not later than 15 days after each Regular Record Date in each year, a
list, in such form as the Trustee may reasonably require, of the names and addresses of the
Holders of Securities of each series to the best knowledge of the Company and the Guarantors as

     (2) at such other times as the Trustee may request in writing, within 30 days after the
receipt by the Company or any Guarantor of any such request, a list of similar form and content

SECTION 702. Preservation of Information; Communications to Holders.

          The Trustee shall preserve, in as current a form as is reasonably practicable, the names and
addresses of Holders contained in the most recent list furnished to the Trustee as provided in
Section 701 and the names and addresses of Holders received by the Trustee in its capacity as
Security Registrar. The Trustee may destroy any list furnished to it as provided in Section 701
upon receipt of a new list so furnished.

          The rights of Holders to communicate with other Holders with respect to their rights under
this Indenture or under the Securities, and the corresponding rights and privileges of the Trustee,
shall be as provided by the Trust Indenture Act.

          Every Holder of Securities, by receiving and holding the same, agrees with the Company, the
Guarantors and the Trustee that neither the Company, the Guarantors nor the Trustee nor any agent
of any of them shall be held accountable by reason of any disclosure of information as to names and
addresses of Holders made pursuant to the Trust Indenture Act.

SECTION 703. Reports by Trustee.

          The Trustee shall transmit to Holders such reports concerning the Trustee and its actions

more than 12 months shall be dated as of May 15 and transmitted no later than July 15 in each

writing or by facsimile when any Securities are listed on any stock exchange.

SECTION 704. Reports by Company and Guarantors.

successor Person formed by such consolidation or into which the Company or such Guarantor is merged
or to which such conveyance, transfer or lease is made shall succeed to, and be substituted for,
and may exercise every right and power of, the Company or such Guarantor, as the case may be, under

predecessor Person shall be relieved of all obligations and covenants under this Indenture and the
Securities.

SECTION 803. Assumption by a Guarantor or Subsidiary of Company’s Obligations.

     Any Guarantor or any Subsidiary of a Guarantor may assume the obligations of the Company (or

for the due and punctual payment of the principal of (and premium, if any), interest on and
any other payments with respect to the Securities and the performance of every covenant of this
Indenture and the Securities on the part of the Company to be performed or observed, provided that:

     (1) such Guarantor or Subsidiary, as the case may be, shall expressly assume such obligations
by an indenture supplemental hereto, in form reasonably satisfactory to the Trustee, executed and
delivered to the Trustee and if such Subsidiary assumes such obligations, the Guarantors shall, by
such supplemental indenture, confirm that their Guarantees shall apply to such Subsidiary’s
obligations under the Securities and this Indenture, as modified by such supplemental indenture;

     (2) such Guarantor or Subsidiary, as the case may be, shall agree in such supplemental
indenture, to the extent provided in the Securities and subject to the limitations and exceptions
set forth below, that if any deduction or withholding for any present or future taxes, assessments
or other governmental charges of the jurisdiction (or any political subdivision or taxing authority
thereof or therein) in which such Guarantor or such Subsidiary is incorporated shall at any time be
required by such jurisdiction (or any such political subdivision or taxing authority) in respect of
any amounts to be paid by such Guarantor or Subsidiary, as the case may be, to a Holder, who, with
respect to any such taxes, 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; provided, however, that such
Guarantor or Subsidiary, as the case may be, shall not be required to make any payment of
additional amounts (i) if the Holder is a United States Person, for or on account of any such tax,
assessment or other governmental charge imposed by the United States or any political subdivision
or taxing authority thereof or therein, (ii) 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) 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;

withholding from payments of (or in respect of) principal of, premium, if any, or any 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 Securities with a request of
such Subsidiary or any Guarantor addressed to the Holder (i) to provide information

53

 

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 Rio Tinto plc under the 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;

     (f) 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;

     (g) any withholding or deduction required to be made with respect to a Security presented
for payment by or on behalf of a Holder of such 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

     (h) 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, amount 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);

     (i) 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

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

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 such 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

54

 

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.

Securities of any series in any material respect.

SECTION 902. Supplemental Indentures With Consent of Holders.

          With the consent of the Holders of not less than a majority in principal amount of the
Outstanding Securities of each series affected by such supplemental indenture, by Act of said

56

 

A supplemental indenture which changes or eliminates any covenant or other provision of this
Indenture which has expressly been included solely for the benefit of one or more particular series
of Securities, or which modifies the rights of the Holders of Securities of such series with
respect to such covenant or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

          It shall not be necessary for any Act of Holders under this Section to approve the particular
form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve
the substance thereof.

SECTION 903. Execution of Supplemental Indentures.

          In executing, or accepting the additional trusts created by, any supplemental indenture
permitted by this Article or the modifications thereby of the trusts created by this Indenture, the

relying upon, in addition to the documents required by Section 102, an Opinion of Counsel stating

SECTION 904. Effect of Supplemental Indentures.

          Upon the execution of any supplemental indenture under this Article, this Indenture shall be

Company and the Guarantors shall so determine, new Securities of any series so modified as to
conform, in the opinion of the Trustee and the Company and the Guarantors, to any such supplemental
indenture may be prepared and executed by the Company, the Guarantees of the Guarantors may be

ARTICLE TEN

COVENANTS

SECTION 1001. Payment of Principal, Premium and Interest.

          The Company covenants and agrees for the benefit of the Holders of each series of Securities
that it will duly and punctually pay the principal of and any premium and interest on the
Securities of that series in accordance with the terms of the Securities and this Indenture.

SECTION 1002. Maintenance of Office or Agency.

          The Company will maintain in each Place of Payment for any series of Securities an office or
agency where Securities of that series may be presented or surrendered for payment, where
Securities of that series may be surrendered for registration of transfer or exchange and where
notices and demands to or upon the Company in respect of the Securities of that series and this
Indenture may be served.

          The Company and the Guarantors will give prompt written notice to the Trustee of the location,
and any change in the location, of such office or agency. If at any time the Company or any
Guarantor shall fail to maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office of the Trustee, and the Company and the Guarantors each
hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

          The Company may also from time to time designate one or more other offices or agencies where
the Securities of one or more series may be presented or surrendered for any or all such purposes
and may from time to time rescind such designations; provided, however, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain an office or
agency in each Place of Payment for Securities of any series for such purposes. The Company will
give prompt written notice to the Trustee of any such designation or rescission and of any change
in the location of any such other office or agency.

SECTION 1003. Money for Securities Payments to Be Held in Trust.

          If the Company or any Guarantor shall at any time act as its own Paying Agent with respect to
any series of Securities, it will, on or before each due 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 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, 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.

58

 

          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 any other obligor upon the Securities of that series)
in the making of any payment in respect of the Securities of that series, 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.

          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.

If the Securities of a series provide for the payment of additional amounts, all payments of, or in
respect of, principal of and any premium and interest on such Securities, and all payments pursuant
to any Guarantee on such Securities shall be made without any deduction or withholding for, or on
account of, any present or future taxes, duties, assessments or other 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 other governmental charges are required
by such jurisdiction (or any such subdivision or taxing authority thereof or therein) to be
withheld or deducted. In that event, the Company or such Guarantor, as applicable, will pay to the
Holder of a Security such additional amounts as may be necessary in order that the net amounts paid
to the Holder of such Security who, with respect to any such tax, assessment, or other governmental
charge, is not resident in such jurisdiction, after such deduction or withholding, shall be not
less than the amounts specified in such Security to which such Holder is entitled; provided
however, that the Company or such Guarantor shall not be required to make any payment of
additional amounts (i) if the Holder is a United States Person for or on account of any such tax,
assessment or other governmental charge imposed by the United States or any political subdivisions
or taxing authority thereof or therein, (ii) for or on account of:

59

 

     (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) 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 form 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) in the case of a payment made by Rio Tinto plc under the 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;

     (f) 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;

     (g) any withholding or deduction required to be made with respect to a Security presented
for payment by or on behalf of a Holder of such 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

     (h) 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, amount 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);

     (i) 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

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

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.

          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 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.

          If the Securities of a series provide for the payment of additional amounts, at least 10 days
prior to the first Interest Payment Date with respect to that series of Securities (or if the
Securities of that series will not bear interest prior to Maturity, the first day on which a
payment of principal and any premium is made), and at least 10 days prior to each date of payment
of principal and any premium or interest if there has been any change with respect to the matters
set forth in the below-mentioned Officer’s Certificate, the Company will furnish the Trustee and
the Company’s principal Paying Agent or Paying Agents, if other than the Trustee, with an Officer’s
Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of
principal of and any premium or interest on the Securities of that series shall be made to Holders
of Securities of that series without withholding for or on account of any tax, assessment or other
governmental charge described in the Securities of that series. If any such withholding shall be
required, then such Officer’s Certificate shall specify by country the amount, if any, required to
be withheld on such payments to such Holders of Securities and the Company or the Guarantor, as the
case may be, will pay to the Trustee or such Paying Agent or Paying Agents the additional amounts
required by this Section. The Company and the Guarantors covenant to indemnify the Trustee and any
Paying Agent for, and to hold them harmless against, any loss, liability or expense reasonably
incurred without negligence or bad faith on their part arising out of or in connection with actions
taken or omitted by any of them in reliance on any Officer’s Certificate furnished pursuant to this
Section.

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.

Guarantor or the Company to such lender or investor or 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:

(1) a Guarantor or the Company could create indebtedness secured by an Encumbrance pursuant

64

 

equal to the indebtedness attributable to such sale and leaseback transaction without
equally and ratably securing the Securities; or

(2) a Guarantor or the Company, within one year after the sale or transfer shall have been

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 1009. 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 any of Sections 1004, 1007 or 1008 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.

ARTICLE ELEVEN

REDEMPTION OF SECURITIES

SECTION 1101. Applicability of Article.

          Securities of any series which are redeemable before 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

65

 

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 to be redeemed,
at his 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 amounts) of the particular Securities to be redeemed and,
if

66

 

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 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

67

 

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 (or
any Subsidiary of any Guarantor which has assumed the Company’s obligations pursuant to Section 803
of this Indenture) 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) 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 (or, in the case of any Subsidiary of any Guarantor which has assumed the
Company’s obligations pursuant to Section 803 of this Indenture, such Subsidiary) 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) (or in the case of an
assumption of the Company’s obligations by any Subsidiary pursuant to Section 803, becomes
effective after the date of such assumption), (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 Section 301(20) (or the supplemental
indenture described in Section 803 of this Indenture) 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

there has been published by, the Internal Revenue Service a ruling or (B) since the date of

     (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

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

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

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.

unfitness to serve.

Company, and you hereby assign to the Company any right or interest that you may otherwise have in
respect thereof. Upon the reasonable request of the Company, you shall execute acknowledge,

termination of the other provisions of this Agreement and the corresponding employment relationship
created hereby.

 

 

     You agree that while you are employed by the Company and for a period of three years
thereafter you will not, without the prior written consent of the Company’s Board of Directors,
induce or attempt to induce any person then, or during the immediately preceding six (6) month

title to the goodwill of the Company (a “Transferee”), whether as an officer, employee, consultant,
salesman, adviser or independent contractor to leave the employ of the Company or such Transferee,
as the case may be, or to cease providing the services to the Company or such Transferee, as the
case may be, then provided by such person, or in any other manner seek to engage or employ any such
person (whether or not for compensation) as an officer, employee, consultant, adviser or
independent contractor such that such person would thereafter be unable to devote his or her full
business time and attention to the business then conducted by the Company or such Transferee, as
the case may be.

     You hereby specifically acknowledge and agree that the restrictions contained in the above
paragraph are reasonable and necessary to protect the business and prospective business of Company,
and that the enforcement of the provisions of this paragraph will not cause an undue hardship on
you.

separate provision hereof shall be construed and enforced as if such illegal invalid, or
unenforceable provision had never comprised a part of this Agreement, and the remaining provisions

agreement between you and the Company with respect to the terms and conditions of your employment,
