substantially identical, except in the case of Registered Securities as to denomination and except
as may otherwise be provided by or pursuant to the Board Resolution or Officer’s Certificate
referred to above or as set forth in any such indenture supplemental hereto. All Securities of any
one series need not be issued at the same time and may pursuant to the Board Resolution or
Officer’s Certificate be issued from time to time, consistent with the terms of this Indenture, if
so provided by or pursuant to such Board Resolution, such Officer’s Certificate or in any such
indenture supplemental hereto.

     Section 2.4 Authentication and Delivery of Securities. (a) The Issuer may deliver
Securities of any series having attached thereto appropriate Coupons, if any, executed by the
Issuer to the Trustee for authentication together with the applicable documents referred to below
in this Section, and the Trustee shall thereupon authenticate and deliver such Securities to or
upon the order of the Issuer (contained in the Issuer Order referred to below in this Section) or
pursuant to such procedures acceptable to the Trustee and to such recipients as may be specified
from time to time by an Issuer Order. The maturity date, original issue date, interest rate and
any other terms of the Securities of such series and Coupons, if any, appertaining thereto shall be
determined by or pursuant to such Issuer Order and procedures. In authenticating such Securities
and accepting the additional responsibilities under this Indenture in relation to such Securities,
the Trustee shall be entitled to receive and (subject to Section 6.1) shall be fully protected in
relying upon, unless and until such documents have been superseded or revoked:

          (i) an Issuer Order requesting such authentication and setting forth delivery instructions if
the Securities and Coupons, if any, are not to be delivered to the Issuer, provided that, with
respect to Securities of a series subject to a Periodic Offering, (1) such Issuer Order may be
delivered by the Issuer to the Trustee prior to the delivery to the Trustee of such Securities for
authentication and delivery, (2) the Trustee shall authenticate and deliver Securities of such
series for original issue from time to time, in an aggregate principal amount not exceeding the
aggregate principal amount established for such series, pursuant to an Issuer Order or pursuant to
procedures acceptable to the Trustee as may be specified from time to time by an Issuer Order and
(3) the maturity date or dates, original issue date or dates, interest rate or rates and any
other terms of Securities of such series shall be determined by an Issuer Order or pursuant to such
procedures;

8

 

          (ii) any Board Resolution, Officer’s Certificate and/or executed supplemental indenture
referred to in Sections 2.1 and 2.3 by or pursuant to which the forms and terms of the Securities
and Coupons, if any, were established;

          (iii) an Officer’s Certificate setting forth the form or forms and terms of the Securities and
Coupons, if any, stating that the form or forms and terms of the Securities and Coupons, if any,
have been established pursuant to Sections 2.1 and 2.3 and comply with this Indenture, and covering
such other matters as the Trustee may reasonably request; and

          (iv) at the option of the Issuer, either one or more Opinions of Counsel, or a letter
addressed to the Trustee permitting it to conclusively rely, as to the truth of the statements and
the correctness of the opinions expressed therein, on one or more Opinions of Counsel,
substantially to the effect that:

               (1) the forms of the Securities and Coupons, if any, have been duly authorized and established
in conformity with the provisions of this Indenture;

               (2) in the case of an underwritten offering, the terms of the Securities have been duly
authorized and established in conformity with the provisions of this Indenture, and, in the case of
an offering that is not underwritten, certain terms of the Securities have been established
pursuant to a Board Resolution, an Officer’s Certificate or a supplemental indenture in accordance
with this Indenture, and when such other terms as are to be established pursuant to procedures set
forth in an Issuer Order shall have been established, all such terms will have been duly authorized
by the Issuer and will have been established in conformity with the provisions of this Indenture;

               (3) when the Securities and Coupons, if any, have been executed by the Issuer and
authenticated by the Trustee in accordance with the provisions of this Indenture and delivered to
and duly paid for by the purchasers thereof, they will have been duly issued under this Indenture,
will be entitled to the benefits of this Indenture, and will be valid and binding obligations of
the Issuer, enforceable in accordance with their respective terms; and

               (4) that all applicable laws and requirements in respect of the execution and delivery by the
Issuer of such Securities have been complied with.

     In rendering such opinions, any counsel may qualify any opinions by stating that the validity
or enforceability of any agreements or instruments may be limited by bankruptcy, insolvency,
reorganization, liquidation, moratorium and other similar laws affecting the rights and remedies of
creditors and by general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law). Such counsel may rely upon opinions of other
counsel (copies of which shall be delivered to the Trustee), who shall be counsel reasonably
satisfactory to the Trustee, in which case the opinion shall state that such counsel believes he or
she and the Trustee are entitled so to rely. Such counsel may also state that, insofar as such
opinion involves factual matters, he or she has relied, to the extent he or she deems proper, upon
certificates of officers of the Issuer and its subsidiaries and certificates of public officials.

     (b) The Trustee shall have the right to decline to authenticate and deliver any Securities
under this Section if the Trustee, being advised by counsel, determines that such action may not
lawfully be taken by the Issuer or if the Trustee in good faith by its board of directors or board
of trustees, executive committee, or a trust committee of directors or trustees or Responsible
Officers shall determine that such action would expose the Trustee to personal liability to
existing Holders or would affect the Trustee’s own rights, duties or immunities under the
Securities, this Indenture or otherwise.

     (c) If the Issuer shall establish pursuant to Section 2.3 that the Securities of a series are
to be issued in whole or in part in global form, then the Issuer shall execute and the Trustee
shall, in accordance with this Section and the Issuer Order with respect to such series,
authenticate and deliver one or more Securities in global form that (i) shall represent and shall
be denominated in an amount equal to the

9

 

aggregate principal amount of all of the Securities of such series issued and not yet
cancelled, (ii) if such Securities are Registered Securities, shall be registered in the name of the
Depositary for such Security or Securities in global form or the
nominee of such Depositary, (iii) if
such Securities are Registered Securities, shall be delivered by the Trustee to such Depositary or
pursuant to such Depositary’s instructions and (iv) shall bear a legend substantially to the
following effect: “Unless and until it is exchanged in whole or in part for Securities in
definitive form, this Security may not be transferred except as a whole by the Depositary to the
nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of
the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of
such successor Depositary.” The Trustee shall have no responsibility for any action taken or not
taken by the Depositary.

     (d) Each Depositary designated pursuant to Section 2.3 must, at the time of its designation
and at all times while it serves as Depositary, be a clearing agency registered under the
Securities Exchange Act of 1934 and any other applicable statute or regulation.

     Section 2.5 Execution of Securities. The Securities and, if applicable, each Coupon
appertaining thereto shall be signed on behalf of the Issuer by the chairman or vice chairman of
its Board of Directors or its president or any executive, senior or other vice president or its
treasurer, but need not, be attested. Such signatures may be the manual or facsimile signatures of
the present or any future such officers. Typographical and other minor errors or defects in any
such signature shall not affect the validity or enforceability of any Security that has been duly
authenticated and delivered by the Trustee.

     In case any officer of the Issuer who shall have signed any of the Securities or Coupons, if
any, shall cease to be such officer before the Security or Coupon so signed (or the Security to
which the Coupon so signed appertains) shall be authenticated and delivered by the Trustee or
disposed of by the Issuer, such Security or Coupon nevertheless may be authenticated and delivered
or disposed of as though the person who signed such Security or Coupon had not ceased to be such
officer of the Issuer; and any Security or Coupon may be signed on behalf of the Issuer by such
persons as, at the actual date of the execution of such Security or Coupon, shall be the proper
officers of the Issuer, although at the date of the execution and delivery of this Indenture any
such person was not such an officer.

     Section 2.6 Certificate of Authentication. Only such Securities as shall bear thereon
a certificate of authentication substantially in the form herein before recited, executed by the
Trustee by the manual signature of one of its authorized signatories, shall be entitled to the
benefits of this Indenture or be valid or obligatory for any purpose. No Coupon shall be entitled
to the benefits of this Indenture or shall be valid and obligatory for any purpose until the
certificate of authentication on the Security to which such Coupon appertains shall have been duly
executed by the Trustee. The execution of such certificate by the Trustee upon any Security
executed by the Issuer shall be conclusive evidence that the Security so authenticated has been
duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this
Indenture.

     Section 2.7 Denomination and Date of Securities; Payments of Interest. The Securities
of each series shall be issuable as Registered Securities or Unregistered Securities in
denominations established as contemplated by Section 2.3 or, with respect to the Registered
Securities of any series, if not so established, in denominations of $1,000 and any integral
multiple thereof. If denominations of Unregistered Securities of any series are not so
established, such Securities shall be issuable in denominations of $1,000 and $5,000. The
Securities of each series shall be numbered, lettered or otherwise distinguished in such manner or
in accordance with such plan as the officers of the Issuer executing the same may determine, as
evidenced by the execution and authentication thereof.

     Each Registered Security shall be dated the date of its authentication. Each Unregistered
Security shall be dated as provided in the resolution or resolutions of the Board of Directors of
the Issuer referred to in Section 2.3. The Securities of each series shall bear interest, if any,
from the date, and such interest shall be payable on the dates, established as contemplated by
Section 2.3.

10

 

     The person in whose name any Registered Security of any series is registered at the close of
business on any record date applicable to a particular series with respect to any interest payment
date for such series shall be entitled to receive the interest, if any, payable on such interest
payment date notwithstanding any transfer or exchange of such Registered Security subsequent to the
record date and prior to such interest payment date, except if and to the extent the Issuer shall
default in the payment of the interest due on such interest payment date for such series, in which
case such defaulted interest shall be paid to the persons in whose names Outstanding Registered
Securities for such series are registered at the close of business on a subsequent record date
(which shall be not less than five Business Days prior to the date of payment of such defaulted
interest) established by notice given by mail by or on behalf of the Issuer to the Holders of
Registered Securities not less than 15 days preceding such subsequent record date. The term
“record date” as used with respect to any interest payment date (except a date for payment of
defaulted interest) for the Securities of any series shall mean the date specified as such in the
terms of the Registered Securities of such series established as contemplated by Section 2.3, or,
if no such date is so established, if such interest payment date is the first day of a calendar
month, the fifteenth day of the next preceding calendar month or, if such interest payment date is
the fifteenth day of a calendar month, the first day of such calendar month, whether or not such
record date is a Business Day.

     Section 2.8 Registration, Transfer and Exchange. (a) The Issuer will keep at each
office or agency to be maintained for the purpose as provided in Section 3.2 for each series of
Securities a register or registers in which, subject to such reasonable regulations as it may
prescribe, it will provide for the registration of Registered Securities of such series and the
registration of transfer of Registered Securities of such series. Such register shall be in
written form in the English language. At all reasonable times such register or registers shall be
open for inspection by the Trustee.

     (b) Upon due presentation for registration of transfer of any Registered Security of any
series at any such office or agency to be maintained for the purpose as provided in Section 3.2,
the Issuer shall execute and the Trustee shall authenticate and deliver in the name of the
transferee or transferees a new Registered Security or Registered Securities of the same series,
maturity date, interest rate and original issue date in authorized denominations for a like
aggregate principal amount.

     Unregistered Securities (except for any temporary Unregistered Securities in global form) and
Coupons (except for Coupons attached to any temporary Unregistered Securities in global form) shall
be transferable by delivery.

     (c) (i) At the option of the Holder thereof, Registered Securities of any series (other than
a Registered Security in global form, except as set forth below) may be exchanged for a Registered
Security or Registered Securities of such series having authorized denominations and an equal
aggregate principal amount, upon surrender of such Registered Securities to be exchanged at the
agency of the Issuer that shall be maintained for such purpose in accordance with Section 3.2 and
upon payment, if the Issuer shall so require, of the charges hereinafter provided. Whenever any
Registered Securities are so surrendered for exchange, the Issuer shall execute, and the Trustee
shall authenticate and deliver, the Registered Securities which the Holder making the exchange is
entitled to receive.

          (ii) Unless otherwise specified as contemplated by Section 2.3, at the option of the Holder,
Unregistered Securities of such series may be exchanged for Registered Securities (if the
Securities of such series are issuable in registered form) or Unregistered Securities (if
Unregistered Securities of such series are issuable in more than one denomination and such
exchanges are permitted by such series) of the same series, of any authorized denominations and of
like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at the
agency of the Issuer that shall be maintained for such purpose in accordance with Section 3.2, with
all unmatured Coupons and all matured Coupons in default thereto appertaining. If the Holder of an
Unregistered Security is unable to produce any such unmatured Coupon or Coupons or matured Coupon
or Coupons in default, such exchange may be effected if the Unregistered Securities are accompanied
by payment in funds acceptable to the Issuer and the Trustee in an amount equal to the face amount
of such missing Coupon or Coupons, or the surrender of such missing Coupon or Coupons may be waived
by the Issuer and the Trustee if there be furnished to them such security or indemnity as they may
require to save each of them and any paying agent harmless. If

11

 

thereafter the Holder of such Security shall surrender to any paying agent any such missing
Coupon in respect of which such a payment shall have been made, such Holder shall be entitled to
receive the amount of such payment as provided in Section 3.2. Notwithstanding the foregoing, in
case any Unregistered Security of any series is surrendered at any such office or agency in
exchange for a Registered Security of the same series after the close of business at such office or
agency on (1) any record date and before the opening of business at such office or agency on the
relevant interest payment date, or (2) any special record date for payment of defaulted interest
and before the opening of business at such office or agency on the related date for payment of
defaulted interest, such Unregistered Security shall be surrendered without the Coupon relating to
such interest or defaulted interest payment date or proposed date of payment, as the case may be
(or, if such Coupon is so surrendered with such Unregistered Security, such Coupon shall be
returned to the person so surrendering the Unregistered Security), and interest or defaulted
interest, as the case may be, will not be payable on such date or proposed date for payment, as the
case may be, in respect of the Registered Security issued in exchange for such Unregistered
Security, but will be payable only to the Holder of such Coupon, when due in accordance with the
provisions of this Indenture.

          (iii) Registered Securities of any series may not be exchanged for Unregistered Securities of
such series unless (1) otherwise specified pursuant to
Section 2.3 and (2) the Issuer has
delivered to the Trustee an Opinion of Counsel that (A) the Issuer has received from the Internal
Revenue Service a ruling or (B) since the date hereof, there has been a change in the applicable
Federal income tax law, in either case to the effect that the inclusion of terms permitting
Registered Securities to be exchanged for Unregistered Securities would result in no adverse
Federal income tax effect to the Issuer or to any Holder. Whenever any Securities are so
surrendered for exchange, the Issuer shall execute, and the Trustee shall authenticate and deliver,
the Securities which the Holder making the exchange is entitled to receive. All Securities and
Coupons surrendered upon any exchange or transfer provided for in this Indenture shall be cancelled
promptly and disposed of by the Trustee in accordance with its procedures for the disposition of
cancelled securities in effect as of the date of such cancellation and the Trustee will deliver a
certificate of disposition thereof to the Issuer.

     (d) All Registered Securities presented for registration of transfer, exchange, redemption or
payment shall (if so required by the Issuer or the Trustee) be duly endorsed by, or be accompanied
by a written instrument or instruments of transfer in form satisfactory to the Issuer and the
Trustee duly executed by the Holder or his or her attorney duly authorized in writing.

     The Issuer may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any exchange or registration of transfer of
Securities. No service charge shall be made for any such transaction.

     The
Issuer shall not be required to exchange or register a transfer of (i) any Securities of
any series for a period of 15 days next preceding the first mailing of notice of redemption of
Securities of such series to be redeemed or (ii) any Securities selected, called or being called for
redemption, in whole or in part, except, in the case of any Security to be redeemed in part, the
portion thereof not so to be redeemed.

     (e) Notwithstanding any other provision of this Section 2.8, unless and until it is exchanged
in whole or in part for Securities in definitive registered form, a Registered Security in global
form representing all or a portion of the Securities of a series may not be transferred except as a
whole by the Depositary for such series to a nominee of such Depositary or by a nominee of such
Depositary to such Depositary or another nominee of such Depositary or by such Depositary or any
such nominee to a successor Depositary for such series or a nominee of such successor Depositary.

     If at any time the Depositary for any Registered Securities of a series represented by one or
more Registered Securities in global form notifies the Issuer that it is unwilling or unable to
continue as Depositary for such Registered Securities or if at any time the Depositary for such
Registered Securities shall no longer be eligible under Section 2.4, the Issuer shall appoint a
successor Depositary eligible under Section 2.4 with respect to such Registered Securities. If a
successor Depositary eligible under Section 2.4 for such Registered Securities is not appointed by
the Issuer within 90 days after the Issuer receives such notice or becomes aware of such
ineligibility, the Issuer’s election pursuant to Section 2.3 that such

12

 

Registered Securities be represented by one or more Registered Securities in global form shall
no longer be effective and the Issuer will execute, and the Trustee, upon receipt of an Officer’s
Certificate for the authentication and delivery of definitive Securities of such series, will
authenticate and deliver, Securities of such series in definitive registered form without Coupons,
in any authorized denominations, in an aggregate principal amount equal to the principal amount of
the Registered Security or Securities in global form representing such Registered Securities in
exchange for such Registered Security or Securities in global form.

     The Issuer may at any time and in its sole discretion determine that the Registered Securities
of any series issued in the form of one or more Registered Securities in global form shall no
longer be represented by a Registered Security or Securities in global form. In such event the
Issuer will execute, and the Trustee, upon receipt of an Issuer Order for the authentication and
delivery of definitive Securities of such series, will authenticate and deliver, Securities of such
series in definitive registered form without Coupons, in any authorized denominations, in an
aggregate principal amount equal to the principal amount of the Registered Security or Securities
in global form representing such Registered Securities, in exchange for such Registered Security or
Securities in global form.

     If specified by the Issuer pursuant to Section 2.3 with respect to Securities represented by a
Registered Security in global form, the Depositary for such Registered Security in global form may
surrender such Registered Security in global form in exchange in whole or in part for Registered
Securities of the same series in definitive form on such terms as are acceptable to the Issuer and
such Depositary. Thereupon, the Issuer shall execute, and the Trustee shall authenticate and
deliver, without service charge,

          (i) to the Person specified by such Depositary a new Registered Security or Securities of the
same series, of any authorized denominations as requested by such Person, in an aggregate principal
amount equal to and in exchange for such Person’s beneficial interest in the Registered Security in
global form; and

          (ii) to such Depositary a new Registered Security in global form in a denomination equal to
the difference, if any, between the principal amount of the surrendered Registered Security in
global form and the aggregate principal amount of Registered Securities authenticated and delivered
pursuant to clause (i) above.

     Upon the exchange of a Registered Security in global form for Registered Securities in
definitive form without Coupons, in authorized denominations, such Registered Security in global
form shall be cancelled by the Trustee or an agent of the Issuer or the Trustee. Registered
Securities in definitive form issued in exchange for a Registered Security in global form pursuant
to this Section 2.8 shall be registered in such names and in such authorized denominations as the
Depositary for such Registered Security in global form, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee or an agent of the Issuer or the
Trustee. The Trustee or such agent shall deliver such Securities to or as directed by the Persons
in whose names such Securities are so registered.

     (f) All Securities issued upon any transfer or exchange of Securities shall be valid
obligations of the Issuer, evidencing the same debt, and entitled to the same benefits under this
Indenture, as the Securities surrendered upon such transfer or exchange.

     (g) Notwithstanding anything herein or in the terms of any series of Securities to the
contrary, none of the Issuer, the Trustee or any agent of the Issuer or the Trustee (any of which,
other than the Issuer, shall conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, on an Officer’s Certificate and an Opinion of
Counsel) shall be required to exchange any Unregistered Security for a Registered Security if such
exchange would result in adverse income tax consequences to the Issuer.

     (h) The Trustee shall have no obligation or duty to monitor, determine or inquire as to
compliance with any restrictions on transfer imposed under this Indenture or under applicable law
with respect to any transfer of any interest in any Security (including any transfers between or
among Depositary

13

 

Participants or beneficial owners of interests in any Global Security) other than to require
delivery of such certificates and other documentation or evidence as are expressly required by, and
to do so if and when expressly required by the terms of, this Indenture, and to examine the same to
determine substantial compliance as to form with the express requirements hereof.

     Section 2.9 Mutilated, Defaced, Destroyed, Lost and Stolen Securities. In case any
Security or any Coupon appertaining to any Security shall become mutilated, defaced or be
destroyed, lost or stolen, the Issuer in its discretion may execute, and upon the written request
of any officer of the Issuer, the Trustee shall authenticate and deliver a new Security of the same
series, maturity date, interest rate and original issue date, bearing a number or other
distinguishing symbol not contemporaneously outstanding, in exchange and substitution for the
mutilated or defaced Security, or in lieu of and in substitution for the Security so destroyed,
lost or stolen with Coupons corresponding to the Coupons appertaining to the Securities so
mutilated, defaced, destroyed, lost or stolen, or in exchange or substitution for the Security to
which such mutilated, defaced, destroyed, lost or stolen Coupon appertained, with Coupons
appertaining thereto corresponding to the Coupons so mutilated, defaced, destroyed, lost or stolen.
In every case the applicant for a substitute Security or Coupon shall furnish to the Issuer and to
the Trustee and any agent of the Issuer or the Trustee such security or indemnity as may be
required by them to indemnify and defend and to save each of them harmless and, in every case of
destruction, loss or theft, evidence to their satisfaction of the destruction, loss or theft of
such Security or Coupon and of the ownership thereof and in the case of mutilation or defacement
shall surrender the Security and related Coupons to the Trustee or such agent.

     Upon the issuance of any substitute Security or Coupon, the Issuer 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) or its agent
connected therewith. In case any Security or Coupon which has matured or is about to mature or has
been called for redemption in full shall become mutilated or defaced or be destroyed, lost or
stolen, the Issuer may instead of issuing a substitute Security, pay or authorize the payment of
the same or the relevant Coupon (without surrender thereof except in the case of a mutilated or
defaced Security or Coupon), if the applicant for such payment shall furnish to the Issuer and to
the Trustee and any agent of the Issuer or the Trustee such security or indemnity as any of them
may require to save each of them harmless, and, in every case of destruction, loss or theft, the
applicant shall also furnish to the Issuer and the Trustee and any agent of the Issuer or the
Trustee evidence to their satisfaction of the destruction, loss or theft of such Security or Coupon
and of the ownership thereof.

     Every substitute Security or Coupon of any series issued pursuant to the provisions of this
Section by virtue of the fact that any such Security or Coupon is destroyed, lost or stolen shall
constitute an additional contractual obligation of the Issuer, whether or not the destroyed, lost
or stolen Security or Coupon shall be at any time enforceable by anyone and shall be entitled to
all the benefits of (but shall be subject to all the limitations of rights set forth in) this
Indenture equally and proportionately with any and all other Securities or Coupons of such series
duly authenticated and delivered hereunder. All Securities and Coupons shall be held and owned
upon the express condition that, to the extent permitted by law, the foregoing provisions are
exclusive with respect to the replacement or payment of mutilated, defaced or destroyed, lost or
stolen Securities and Coupons and shall preclude any and all other rights or remedies
notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to
the replacement or payment of negotiable instruments or other securities without their surrender.

     Section 2.10 Cancellation of Securities; Destruction Thereof. All Securities and
Coupons surrendered for payment, redemption, registration of transfer or exchange, or for credit
against any payment in respect of a sinking or analogous fund, if surrendered to the Issuer or any
agent of the Issuer or the Trustee or any agent of the Trustee, shall be delivered to the Trustee
or its agent for cancellation or, if surrendered to the Trustee, shall be cancelled by it; and no
Securities or Coupons shall be issued in lieu thereof except as expressly permitted by any of the
provisions of this Indenture. The Trustee or its agent shall dispose of cancelled Securities and
Coupons held by it in accordance with its procedures for the disposition of cancelled securities
in effect as of the date of such cancellation. If the Issuer or its agent shall acquire any of the
Securities or Coupons, such acquisition shall not operate as a redemption or

14

 

satisfaction of the indebtedness represented by such Securities or Coupons unless and until
the same are delivered to the Trustee or its agent for cancellation.

     Section 2.11 Temporary Securities. Pending the preparation of definitive Securities
for any series, the Issuer may execute and the Trustee shall authenticate and deliver temporary
Securities for such series (printed, lithographed, typewritten or otherwise reproduced, in each
case in form satisfactory to the Trustee). Temporary Securities of any series shall be issuable as
Registered Securities without Coupons, or as Unregistered Securities with or without Coupons
attached thereto, of any authorized denomination, and substantially in the form of the definitive
Securities of such series but with such omissions, insertions and variations as may be appropriate
for temporary Securities, all as may be determined by the Issuer with the concurrence of the
Trustee as evidenced by the execution and authentication thereof. Temporary Securities may contain
such references to any provisions of this Indenture as may be appropriate. Every temporary
Security shall be executed by the Issuer and be authenticated by the Trustee upon the same
conditions and in substantially the same manner, and with like effect, as the definitive
Securities. Without unreasonable delay the Issuer shall execute and shall furnish definitive
Securities of such series and thereupon temporary Registered Securities of such series may be
surrendered in exchange therefor without charge at each office or agency to be maintained by the
Issuer for that purpose pursuant to Section 3.2 and, in the case of Unregistered Securities, at any
agency maintained by the Issuer for such purpose as specified pursuant to Section 3.2, and the
Trustee shall authenticate and deliver in exchange for such temporary Securities of such series an
equal aggregate principal amount of definitive Securities of the same series having authorized
denominations and, in the case of Unregistered Securities, having attached thereto any appropriate
Coupons. Until so exchanged, the temporary Securities of any series shall be entitled to the same
benefits under this Indenture as definitive Securities of such series, unless otherwise established
pursuant to Section 2.3. The provisions of this Section are subject to any restrictions or
limitations on the issue and delivery of temporary Unregistered Securities of any series that may
be established pursuant to Section 2.3 (including any provision that Unregistered Securities of
such series initially be issued in the form of a single Unregistered Security in global form to be
delivered to a Depositary or agency located outside the United States and the procedures pursuant
to which Unregistered Securities in definitive or global form of such series would be issued in
exchange for such temporary Unregistered Security in global form).

     Section 2.12 Global Securities. Neither the Trustee nor any Agent shall have any
responsibility for any actions taken or not taken by the Depositary.

     None of the Issuer, the Trustee, any paying agent, any Security registrar or any other agent
of the Issuer or any agent of the Trustee shall have any responsibility or liability for any aspect
of the records relating to or payments made on account of beneficial ownership interests of a
Security in global form or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests. The Issuer, the Trustee, any paying agent, any Security registrar
and any other agent of the Issuer and any agent of the Trustee shall be entitled to deal with the
Depositary, and any nominee thereof, that is the Holder of any such global Security for all
purposes of this Indenture relating to such global Security (including the payment of principal,
premium, if any, and interest and additional amounts, if any, and the giving of instructions or
directions by or to the owner or holder of a beneficial ownership interest in such global Security)
as the sole Holder of such global Security and shall have no obligations to the beneficial owners
thereof. None of the Issuer, the Trustee, any paying agent, any Security registrar or any other
agent of the Issuer or any agent of the Trustee shall have any responsibility or liability for any
acts or omissions of any such Depositary with respect to such global Security, for the records of
any such Depositary, including records in respect of beneficial ownership interests in respect of
any such global Security, for any transactions between such Depositary and any participant in such
Depositary or between or among any such Depositary, any such participant and/or any holder or owner
of a beneficial interest in such global Security or for any transfers of beneficial interests in
any such global Security. Notwithstanding the foregoing, with respect to any Security in global
form, nothing herein shall prevent the Issuer, the Trustee, or any agent of the Issuer or the
Trustee, from giving effect to any written certification, proxy or other authorization furnished by
the Depositary, as a Holder with respect to such global Security, or impair, as between such
Depositary and owners of beneficial interests in such global Security, the operation of

15

 

customary practices governing the exercise of the rights of such Depositary as a Holder of
such global Security.

     Section 2.13 CUSIP Numbers. The Issuer in issuing the Securities may use “CUSIP,”
“ISIN” or other similar numbers (if then generally in use), and, if so used by the Issuer, the
Trustee shall use “CUSIP,” “ISIN” or other similar 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. The Issuer will promptly notify the Trustee of any change in the
“CUSIP,” “ISIN” or other similar numbers.

ARTICLE 3

COVENANTS OF THE ISSUER

     Section 3.1 Payment of Principal, Premium and Interest. The Issuer covenants and
agrees for the benefit of each series of Securities that it will duly and punctually pay or cause
to be paid the principal of, and premium, if any, and interest on, each of the Securities of such
series (together with any additional amounts payable pursuant to the terms of such Securities) at
the place or places, at the respective times and in the manner provided in such Securities and in
the Coupons, if any, appertaining thereto and in this Indenture. The interest on Securities with
Coupons attached (together with any additional amounts payable pursuant to the terms of such
Securities) shall be payable only upon presentation and surrender of the several Coupons for such
interest installments as are evidenced thereby as they severally mature. If any temporary
Unregistered Security provides that interest thereon may be paid while such Security is in
temporary form, the interest on any such temporary Unregistered Security (together with any
additional amounts payable pursuant to the terms of such Security) shall be paid, as to the
installments of interest evidenced by Coupons attached thereto, if any, only upon presentation and
surrender thereof, and, as to the other installments of interest, if any, only upon presentation of
such Securities for notation thereon of the payment of such interest, in each case subject to any
restrictions that may be established pursuant to Section 2.3. The interest on Registered
Securities (together with any additional amounts payable pursuant to the terms of such Securities)
shall be payable only to or upon the written order of the Holders thereof and, at the option of the
Issuer, may be paid by wire transfer or by mailing checks for such interest payable to or upon the
written order of such Holders at their last addresses as they appear on the registry books of the
Issuer.

     Section 3.2 Offices for Payments, Etc. So long as any Securities are issued as
Registered Securities, the Issuer will maintain in the Borough of Manhattan, The City of New York,
an office or agency where the Registered Securities of each series may be presented for payment,
where the Securities of each series may be presented for exchange as is provided in this Indenture
and, if applicable, pursuant to Section 2.3 and where the Registered Securities of each series may
be presented for registration of transfer as in this Indenture provided.

     So long as any Securities are issued as Unregistered Securities, the Issuer will maintain one
or more offices or agencies in a city or cities located outside the United States (including any
city in which such an agency is required to be maintained under the rules of any stock exchange on
which the Securities of such series are listed) where the Unregistered Securities, if any, of each
series and Coupons, if any, appertaining thereto may be presented for payment. No payment on any
Unregistered Security or Coupon will be made upon presentation of such Unregistered Security or
Coupon at an agency of the Issuer within the United States nor will any payment be made by transfer
to an account in, or by mail to an address in, the United States unless pursuant to applicable
United States laws and regulations then in effect such payment can be made without adverse tax
consequences to the Issuer. Notwithstanding the foregoing, payments in Dollars of Unregistered
Securities of any series and Coupons appertaining thereto which are payable in Dollars may be made
at an agency of the Issuer maintained in the Borough of Manhattan, The City of New York, if such
payment in Dollars at each agency maintained by the Issuer outside the United

16

 

States for payment on such Unregistered Securities is illegal or effectively precluded by
exchange controls or other similar restrictions.

     The Issuer will maintain in the Borough of Manhattan, The City of New York, an office or
agency where notices and demands to or upon the Issuer in respect of the Securities of any series,
the Coupons appertaining thereto or this Indenture may be served.

     The Issuer will give to the Trustee written notice of the location of each such office or
agency and of any change of location thereof. In case the Issuer shall fail to maintain any agency
required by this Section, or shall fail to give such notice of the location or of any change in the
location of any of the above agencies, presentations and demands may be made and notices may be
served at the Corporate Trust Office of the Trustee.

     The Issuer may from time to time designate one or more additional offices or agencies where
the Securities of a series and any Coupons appertaining thereto may be presented for payment, where
the Securities of that series may be presented for exchange as provided in this Indenture and
pursuant to Section 2.3 and where the Registered Securities of that series may be presented for
registration of transfer as in this Indenture provided, and the Issuer may from time to time
rescind any such designation, as the Issuer may deem desirable or expedient; provided, however,
that no such designation or rescission shall in any manner relieve the Issuer of its obligation to
maintain the agencies provided for in this Section. The Issuer will give to the Trustee prompt
written notice of any such designation or rescission thereof.

     Section 3.3 Money for Security Payments to be Held in Trust; Unclaimed Money. If the
Issuer shall at any time act as its own paying agent, it will, on or before each due date of the
principal of and premium, if any, or interest on any of the Securities, segregate and hold in trust
for the benefit of the Holders entitled thereto a sum sufficient to pay the principal (and premium,
if any) or interest so becoming due until such sums shall be paid to such Holders or otherwise
disposed of as herein provided and will promptly notify the Trustee of its action or failure so to
act.

     Whenever the Issuer shall have one or more paying agents, it will, on or prior to each due
date of the principal of and premium, if any, or interest on any Securities, deposit with the
paying agent or paying agents a sum sufficient to pay the principal, premium, if any, or interest
so becoming due, such sum to be held in trust for the benefit of the Holders entitled to such
principal, premium, if any, or interest, and, unless such paying agent is the Trustee, the Issuer
will promptly notify the Trustee of its action or failure so to act.

     The Issuer will cause each paying agent 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:

     (a) hold all sums held by it for the payment of the principal of and premium, if any, or
interest on Securities in trust for the benefit of the Holders entitled thereto until such sums
shall be paid to such Persons or otherwise disposed of as herein provided;

     (b) give the Trustee notice of any default by the Issuer (or any other obligor upon the
Securities) in the making of any payment of principal and premium, if any, or interest; and

     (c) at any time during the continuance of any such default, upon the written request of the
Trustee, forthwith pay to the Trustee all sums so held in trust by such paying agent.

     The Issuer may at any time, for the purpose of obtaining the satisfaction and discharge of
this Indenture or for any other purpose, pay, or by Issuer Order direct any paying agent to pay, to
the Trustee all sums held in trust by the Issuer 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 Issuer or such paying
agent; and, upon such

17

 

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 Issuer in trust
for the payment of the principal of and premium, if any, or interest on any Security and remaining
unclaimed for two years after such principal and premium, if any, or interest has become due and
payable shall be paid to the Issuer on Issuer Order, or, if then held by the Issuer, shall be
discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured
general creditor, look only to the Issuer for payment thereof, and all liability of the Trustee or
such paying agent with respect to such trust money, and all liability of the Issuer as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such paying agent, before
being required to make any such repayment, may (but shall not be obligated to), at the expense of
the Issuer, cause to be published at least once, in an Authorized Newspaper in the Borough of
Manhattan, The City of New York, and at least once in an Authorized Newspaper in London, 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 Issuer.

     Section 3.4 Statements of Officers of Issuer as to Default; Notice of Default. The
Issuer will deliver to the Trustee, within 120 days after the end of each fiscal year of the Issuer
ending after the date hereof, a certificate, signed by the Issuer’s principal executive officer,
principal financial officer or principal accounting officer, stating whether or not to the best
knowledge of the signer thereof the Issuer is in default (without regard to periods of grace or
requirements of notice provided hereunder) in the performance and observance of any of the terms,
provisions and conditions hereof, and if the Issuer shall be in default, specifying all such
defaults and the nature and status thereof of which such signer may have knowledge.

     Section 3.5
Existence. Subject to Article 9, the Issuer will do or cause to be done
all things necessary to preserve and keep in full force and effect its existence, rights (charter
and statutory) and franchises and those of each of its Subsidiaries; provided, however, that the
Issuer shall not be required to preserve any such right or franchise if its Board of Directors
shall determine that the preservation thereof is no longer desirable in the conduct of the business
of the Issuer or the business of any Subsidiary and that the loss thereof is not disadvantageous in
any material respect to the Holders.

     Section 3.6 Maintenance of Properties. The Issuer will cause all properties used or
useful in the conduct of its business or the business of any Subsidiary to be maintained and kept
in good condition, repair and working order and supplied with all necessary equipment and will
cause to be made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Issuer may be necessary so that the business carried on in
connection therewith may be properly and advantageously conducted at all times; provided, however,
that nothing in this Section shall prevent the Issuer from discontinuing the operation or
maintenance of any such properties if such discontinuance is, in the judgment of the Issuer,
desirable in the conduct of its business or the business of any Subsidiary and not disadvantageous
in any material respect to the Holders.

     Section 3.7 Payment of Taxes and Other Claims. The Issuer shall pay or discharge or
cause to be paid or discharged, before the same shall become delinquent, (1) all taxes, assessments
and governmental charges (including withholding taxes and any penalties, interest and additions to
taxes) levied or imposed upon the Issuer or any Subsidiary or upon the income, profits or property
of the Issuer or any Subsidiary, and (2) all material lawful claims for labor, materials and
supplies which, if unpaid, might by law become a lien upon the property of the Issuer or any
Subsidiary; provided, however, that the Issuer shall not be required to pay or discharge or cause
to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or
validity is being contested in good faith by appropriate proceedings and for which disputed amounts
adequate reserves have been made.

     Section 3.8 Further Instruments and Acts. Upon request of the Trustee, the Issuer
will execute and deliver such further instruments and perform such further acts as may be
reasonably necessary or proper to carry out more effectively the purposes of this Indenture.

18

 

     Section 3.9 [Reserved]

     Section 3.10 Luxembourg Publications. In the event of the publication of any notice
pursuant to Section 3.3, 5.11, 6.10, 6.11, 8.2 or 12.2, the party making such publication in the
Borough of Manhattan, The City of New York and London shall also, to the extent that notice is
required to be given to Holders of Securities of any series by applicable Luxembourg law or stock
exchange regulation, as evidenced by an Officer’s Certificate delivered to such party, make a
similar publication in Luxembourg.

     Section 3.11 Commission Reports. The Issuer shall file with the Trustee, within 15
days after it files such annual and quarterly reports, information, documents and other reports
with the Commission, copies of its annual report and of the information, documents and other
reports (or copies of such portions of any of the foregoing as the Commission may by rules and
regulations prescribe) which the Issuer is required to file with the Commission pursuant to Section
13 or 15(d) of the Securities Exchange Act of 1934. Delivery of such reports, information and
documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall
not constitute constructive notice of any information contained therein or determinable from
information contained therein, including the Issuer’s compliance with any of its covenants
hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates). The
Trustee shall be under no obligation to analyze or make any credit decisions with respect to
reports or other information received by it pursuant to this section, but shall hold such reports
and other information solely for the benefit of, and review by, the security holders.

     Section 3.12 Calculation of Original Issue Discount. The Issuer shall file with the
Trustee promptly at the end of each calendar year (i) a written notice specifying the amount of
original issue discount (including daily rates and accrual periods), if any, accrued on Outstanding
Securities as of the end of such year and (ii) such other specific information relating to such
original issue discount as may then be relevant under the Internal Revenue Code of 1986, as amended
from time to time.

ARTICLE 4

SECURITYHOLDERS LISTS AND REPORTS BY THE ISSUER AND THE TRUSTEE

     Section 4.1 Issuer to Furnish Trustee Information as to Names and Addresses of
Securityholders. If and so long as the Trustee shall not be the Security registrar for the
Securities of any series, the Issuer and any other obligor on the Securities will furnish or cause
to be furnished to the Trustee a list in such form as the Trustee may reasonably require of the
names and addresses of the Holders of the Registered Securities of such series pursuant to Section
312 of the Trust Indenture Act of 1939 (1) semi-annually not more than 5 days after each record
date for the payment of interest on such Registered Securities, as hereinabove specified, as of
such record date and on dates to be determined pursuant to Section 2.3 for non-interest bearing
Registered Securities in each year, and (2) at such other times as the Trustee may request in
writing, within thirty days after receipt by the Issuer of any such request as of a date not more
than 15 days prior to the time such information is furnished.

     Section 4.2 Preservation of Information; Communications to Holders. (a) 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 4.1 and
the names and addresses of Holders received by the Trustee in its capacity as Security registrar or
paying agent. The Trustee may destroy any list furnished to it as provided in Section 4.1 upon
receipt of a new list so furnished.

     (b) 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 of 1939.

     (c) Every Holder of Securities, by receiving and holding the same, agrees with the Issuer and
the Trustee that neither the Issuer nor the Trustee nor any agent of any of them shall be held
accountable by reason of the disclosure of any such information as to the names and addresses of
the Holders in accordance with Sections 4.1 and 4.2(b), regardless of the source from which such
information was

19

 

derived, and that the Trustee shall not be held accountable by reason of mailing any material
pursuant to a request made under Section 4.2(b).

     Section 4.3 Reports by the Trustee. Any Trustee’s report required under Section
313(a) of the Trust Indenture Act of 1939 shall be transmitted within 60 days after April 15 in

as any Securities are Outstanding hereunder, and shall be dated as of such April 15.

     A copy of each such report shall, at the time of such transmission to Holders, be filed by the
Trustee with each stock exchange, if any, upon which the Securities are listed, with the Commission
and with the Issuer. The Issuer will promptly notify the Trustee when the Securities are listed on
any stock exchange and of any delisting thereof.

ARTICLE 5

REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS ON EVENT OF DEFAULT

     Section 5.1 Event of Default Defined; Acceleration of Maturity; Waiver of Default.
“Event of Default” with respect to Securities of any series wherever used herein, means each one of
the following events which shall have occurred and be continuing (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected by operation of
law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of
any administrative or governmental body) unless it is either inapplicable to a particular series or
it is specifically deleted or modified in an indenture supplemental hereto, if any, under which
such series of Securities is issued:

     (a) default in the payment of any installment of interest upon any of the Securities of such
series as and when the same shall become due and payable, and continuance of such default for a
period of 30 days and the interest payment date has not been properly extended or deferred;
provided, however, that if the Issuer is permitted by the terms of the Securities of the applicable
series to defer the payment in question, the date on which such payment is due and payable shall be
the date on which the Issuer is required to make payment following such deferral, if such deferral
has been elected pursuant to the terms of the Securities of that series (subject to any deferral of
any due date in the case of an Extension Period); or

     (b) default in the payment of all or any part of the principal of, or premium, if any, on any
of the Securities of such series as and when the same shall become due and payable either at
maturity, upon any redemption, by declaration or otherwise; provided, however, that if the Issuer
is permitted by the terms of the Securities of the applicable series to defer the payment in
question, the date on which such payment is due and payable shall be the date on which the Issuer
is required to make payment following such deferral, if such deferral has been elected pursuant to
the terms of the Securities of that series (subject to any deferral of any due date in the case of
an Extension Period); or

     (c) default in the payment of any sinking fund installment as and when the same shall become
due and payable by the terms of the Securities of such series; or

     (d) failure on the part of the Issuer duly to observe or perform any other of the covenants or
agreements on the part of the Issuer in the Securities of such series (other than a covenant or
agreement in respect of the Securities of such series a default in the performance or breach of
which is elsewhere in this Section specifically dealt with) or contained in this Indenture (other
than a covenant or agreement included in this Indenture solely for the benefit of a series of
Securities other than such series) for a period of 90 days after the date on which written notice
specifying such failure, stating that such notice is a “Notice of Default” hereunder and demanding
that the Issuer remedy the same, shall have been given by registered or certified mail, return
receipt requested, to the Issuer by the Trustee, or to the Issuer and the Trustee by the holders of
at least 25% in aggregate principal amount of the Outstanding Securities of all series affected
thereby; or

     (e) [Reserved]; or

     (f) the Issuer shall commence a voluntary case under any applicable bankruptcy, insolvency or
other similar law now or hereafter in effect, or consent to the entry of an order for relief in an
involuntary case under any such law, or consent to the appointment or taking possession by a
receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official) of the
Issuer or for any substantial part of its property, or make any general assignment for the benefit
of creditors, or shall admit in writing its inability to pay its debts generally as they become
due; or

     (g) [Reserved]; or

     (h) any other Event of Default provided in the supplemental indenture under which such series
of Securities is issued or in the form of Security for such series.

     If
an Event of Default (other than an Event of Default specified in Section 5.1(f)) with
respect to Securities of any series then Outstanding occurs and is continuing, then, and in each
and every such case, except for any series of Securities the principal of which shall have already
become due and payable, either the Trustee or the Holders of not less than 25% in aggregate
principal amount of the Securities of each such affected series then Outstanding hereunder (voting
as a single class) by notice in writing to the Issuer (and to the Trustee if given by
Securityholders), may declare the entire principal (or, if the Securities of any such affected
series are Original Issue Discount Securities, such portion of the principal amount as may be
specified in the terms of such series) of all Securities of all such affected series, and the
interest accrued thereon, if any, to be due and payable immediately, and upon any such declaration,
the same shall become immediately due and payable. If an Event of
Default specified in clause (f)
occurs, all unpaid principal (or, if any Securities are Original Issue Discount Securities, such
portion of the principal as may be specified in the terms thereof) of all the Securities then
Outstanding, and interest accrued thereon, if any, shall be due and payable immediately, without
any declaration or other act on the part of the Trustee or any Securityholder.

     The foregoing provisions, however, are subject to the condition that if, at any time after the
principal (or, if the Securities are Original Issue Discount Securities, such portion of the
principal as may be specified in the terms thereof) of the Securities of any series (or of all the
Securities, as the case may be) shall have been so declared due and payable, and before any
judgment or decree for the payment of the monies due shall have been obtained or entered as
hereinafter provided, the Issuer shall pay or shall deposit with the Trustee a sum sufficient to
pay all matured installments of interest upon all the Securities of such series (or of all the
Securities, as the case may be) and the principal of any and all Securities of each such series (or
of all the Securities, as the case may be) which shall have become due otherwise than by
acceleration (with interest upon such principal and, to the extent that payment of such interest is
enforceable under applicable law, on overdue installments of interest, at the same rate as the rate
of interest or Yield to Maturity (in the case of Original Issue Discount Securities) specified in
the Securities of each such series (or at the respective rates of interest or Yields to Maturity of
all the Securities, as the case may be) to the date of such payment or deposit) and such amount as
shall be sufficient to cover all amounts due to the Trustee, including reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and if any and all
Events of Default under the Indenture, other than the non-payment of the principal of Securities
which shall have become due by acceleration, shall have been cured, waived or otherwise remedied as
provided herein, then and in every such case the Holders of a majority in aggregate principal
amount of all the Securities of each such series, or of all the Securities, in each case voting as
a single class, then Outstanding, by written notice to the Issuer and to the Trustee, may waive all
defaults with respect to each such series (or with respect to all the Securities, as the case may
be) and rescind and annul such declaration and its consequences, but no such waiver or rescission
and annulment shall extend to or shall affect any subsequent default or shall impair any right
consequent thereon.

     For all purposes under this Indenture, if a portion of the principal of any Original Issue
Discount Securities shall have been accelerated and declared due and payable pursuant to the
provisions hereof, then, from and after such declaration, unless such declaration has been
rescinded and annulled, the principal amount of such Original Issue Discount Securities shall be
deemed, for all purposes hereunder, to be such

21

 

portion of the principal thereof as shall be due and payable as a result of such acceleration,
and payment of such portion of the principal thereof as shall be due and payable as a result of
such acceleration, together with interest, if any, thereon and all other amounts owing thereunder,
shall constitute payment in full of such Original Issue Discount Securities.

     Section 5.2 Collection of Indebtedness by Trustee; Trustee May Prove Debt. (a) The
Issuer covenants that (i) in case default shall be made in the payment of any installment of
interest on any of the Securities of any series when such interest shall have become due and
payable, and such default shall have continued for a period of
30 days or (ii) in case default shall
be made in the payment of all or any part of the principal of any of the Securities of any series
when the same shall have become due and payable, whether upon maturity of the Securities of such
series or upon any redemption or by declaration or otherwise, then upon demand of the Trustee, the
Issuer will pay to the Trustee for the benefit of the Holders of the Securities of such series the
whole amount that then shall have become due and payable on all Securities of such series, and such
Coupons, for principal or interest, as the case may be (with interest to the date of such payment
upon the overdue principal and, to the extent that payment of such interest is enforceable under
applicable law, on overdue installments of interest at the same rate as the rate of interest or
Yield to Maturity (in the case of Original Issue Discount Securities) specified in the Securities
of such series); and in addition thereto, such further amount as shall be sufficient to cover all
amounts due to the Trustee, including reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel.

     Until such demand is made by the Trustee, the Issuer may pay the principal of and interest on
the Securities of any series to the registered holders, whether or not the Securities of such
series be overdue.

     (b) In case the Issuer shall fail forthwith to pay such amounts upon such demand, the Trustee,
in its own name and as trustee of an express trust, shall be entitled and empowered to institute
any action or proceedings at law or in equity for the collection of the sums so due and unpaid, and
may prosecute any such action or proceedings to judgment or final decree, and may enforce any such
judgment or final decree against the Issuer or other obligor upon the Securities and collect in the
manner provided by law out of the property of the Issuer or other obligor upon the Securities,
wherever situated the monies adjudged or decreed to be payable.

     (c) In case there shall be pending proceedings relative to the Issuer or any other obligor
upon the Securities under Title 11 of the United States Code or any other applicable Federal or
state bankruptcy, insolvency or other similar law, or in case a receiver, assignee or trustee in
bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been
appointed for or taken possession of the Issuer or its property or such other obligor, or in case
of any other comparable judicial proceedings relative to the Issuer or other obligor upon the
Securities, or to the creditors or property of the Issuer or such other obligor, the Trustee,
irrespective of whether the principal of the Securities shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made
any demand pursuant to the provisions of this Section, shall be entitled and empowered, by
intervention in such proceedings or otherwise:

          (i) to file and prove a claim or claims for the whole amount of principal and interest (or, if
the Securities of any series are Original Issue Discount Securities, such portion of the principal
amount as may be specified in the terms of such series) owing and unpaid in respect of the
Securities of any series, and to file such other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee (including any claim for reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents, and counsel) and of
the Securityholders allowed in any judicial proceedings relative to the Issuer or other obligor
upon the Securities, or to the creditors or property of the Issuer or such other obligor,

          (ii) unless prohibited by applicable law and regulations, to vote on behalf of the holders of
the Securities of any series in any election of a trustee or a standby trustee in arrangement,
reorganization, liquidation or other bankruptcy or insolvency proceedings or person performing
similar functions in comparable proceedings, and

22

 

          (iii) to collect and receive any monies or other property payable or deliverable on any such
claims, and to distribute all amounts received with respect to the claims of the Securityholders
and of the Trustee on their behalf; and any trustee, receiver, or liquidator, custodian or other
similar official is hereby authorized by each of the Securityholders to make payments to the
Trustee, and, in the event that the Trustee shall consent to the making of payments directly to the
Securityholders, to pay to the Trustee such amounts as shall be sufficient to cover all amounts due
to the Trustee, including reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents, and counsel.

     Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to
or vote for or accept or adopt on behalf of any Securityholder any plan of reorganization,
arrangement, adjustment or composition affecting the Securities of any series or the rights of any
Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Securityholder
in any such proceeding except, as aforesaid, to vote for the election of a trustee in bankruptcy or
similar person.

     (d) All rights of action and of asserting claims under this Indenture, or under any of the
Securities of any series or Coupons appertaining to such Securities, may be enforced by the Trustee
without the possession of any of such Securities or Coupons or the production thereof in any trial
or other proceedings relative thereto, and any such action or proceedings instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any recovery of judgment,
subject to the payment of all amounts due to the Trustee, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, shall be for the
ratable benefit of the Holders of the Securities or Coupons appertaining to such Securities in
respect of which such action was taken.

     (e) In any proceedings brought by the Trustee (and also any proceedings involving the
interpretation of any provision of this Indenture to which the Trustee shall be a party) the
Trustee shall be held to represent all the Holders of the Securities or Coupons appertaining to
such Securities in respect to which such action was taken, and it shall not be necessary to make
any Holders of such Securities or Coupons appertaining to such Securities parties to any such
proceedings.

     Section 5.3 Application of Proceeds. Any monies or property collected by the Trustee
pursuant to this Article, or distributable in respect of the Issuer ‘s obligations under this
Indenture, in respect of any series shall, subject to the subordination provisions hereof, be
applied in the following order at the date or dates fixed by the Trustee and, in case of the
distribution of such monies on account of principal or interest, upon presentation of the several
Securities and Coupons appertaining to such Securities in respect of which monies have been
collected and stamping (or otherwise noting) thereon the payment, or issuing Securities of such
series in reduced principal amounts in exchange for the presented Securities of like series if only
partially paid, or upon surrender thereof if fully paid:

     FIRST: To the payment of all amounts due to the Trustee under Section 6.6;

     SECOND: In case the principal of the Securities of such series in respect of which monies
have been collected shall not have become and be then due and payable, to the payment of interest
on the Securities of such series in default in the order of the maturity of the installments of
such interest, with interest (to the extent that such interest has been collected by the Trustee)
upon the overdue installments of interest at the same rate as the rate of interest or Yield to
Maturity (in the case of Original Issue Discount Securities) specified in such Securities, such
payments to be made ratably to the persons entitled thereto, without discrimination or preference;

     THIRD: In case the principal of the Securities of such series in respect of which monies have
been collected shall have become and shall be then due and payable, to the payment of the whole
amount then owing and unpaid upon all the Securities of such series for principal and interest,
with interest upon the overdue principal, and (to the extent that such interest has been collected
by the Trustee) upon overdue installments of interest at the same rate as the rate of interest or
Yield to Maturity (in the case of Original Issue Discount Securities) specified in the Securities
of such series; and in case such monies shall be insufficient to pay in full the whole amount so
due and unpaid upon the Securities of such series, then to the payment of such principal and
interest or Yield to Maturity, without preference or priority of principal over

23

 

interest or Yield to Maturity, or of interest or Yield to Maturity over principal, or of any
installment of interest over any other installment of interest, or of any Security of such series
over any other Security of such series, ratably to the aggregate of such principal and accrued and
unpaid interest or Yield to Maturity; and

     FOURTH: To the payment of the remainder, if any, to the Issuer or any other Person lawfully
entitled thereto.

     Section 5.4 Suits for Enforcement. In case an Event of Default has occurred, has not
been waived and is continuing, the Trustee may in its discretion proceed to protect and enforce the
rights vested in it by this Indenture by such appropriate judicial proceedings as the Trustee shall
deem most effectual to protect and enforce any of such rights, either at law or in equity or in
bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement
contained in this Indenture or in aid of the exercise of any power granted in this Indenture or to
enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

     Section 5.5 Restoration of Rights on Abandonment of Proceedings. In case the Trustee
shall have proceeded to enforce any right under this Indenture and such proceedings shall have been
discontinued or abandoned for any reason, or shall have been determined adversely to the Trustee,
then and in every such case the Issuer and the Trustee shall be restored respectively to their
former positions and rights hereunder, and all rights, remedies and powers of the Issuer, the
Trustee and the Securityholders shall continue as though no such proceedings had been taken.

     Section 5.6 Limitations on Suits by Securityholders. No Holder of any Security of any
series or of any Coupon appertaining thereto shall have any right by virtue or by availing of any
provision of this Indenture to institute any action or proceeding at law or in equity or in
bankruptcy or otherwise upon or under or with respect to this Indenture, or for the appointment of
a trustee, receiver, liquidator, custodian or other similar official or for any other remedy
hereunder, unless such Holder previously shall have given to the Trustee written notice of default
and of the continuance thereof, as hereinbefore provided, and unless also the Holders of not less
than 25% in aggregate principal amount of the Securities of each affected series then Outstanding
(treated as a single class) shall have made written request upon the Trustee to institute such
action or proceedings in its own name as trustee hereunder and shall have offered to the Trustee
such indemnity reasonably satisfactory to it against the costs, expenses and liabilities to be
incurred therein or thereby and the Trustee for 60 days after its receipt of such notice, request
and offer of indemnity shall have failed to institute any such action or proceeding and no
direction inconsistent with such written request shall have been given to the Trustee pursuant to
Section 5.9; it being understood and intended, and being expressly covenanted by the taker and
Holder of every Security or Coupon with every other taker and Holder and the Trustee, that no one
or more Holders of Securities of any series or Coupons appertaining to such Securities shall have
any right in any manner whatever by virtue or by availing of any provision of this Indenture to
affect, disturb or prejudice the rights of any other such Holder of Securities or Coupons
appertaining to such Securities, or to obtain or seek to obtain priority over or preference to any
other such Holder or to enforce any right under this Indenture, except in the manner herein
provided and for the equal, ratable and common benefit of all Holders of Securities of the
applicable series and Coupons appertaining to such Securities. For the protection and enforcement
of the provisions of this Section, each and every Securityholder and the Trustee shall be entitled
to such relief as can be given either at law or in equity.

     Section 5.7 Unconditional Right of Securityholders to Institute Certain Suits.
Notwithstanding any other provision in this Indenture and any provision of any Security, the right
of any Holder of any Security or Coupon to receive payment of the principal of and interest on such
Security or Coupon on or after the respective due dates expressed in such Security or Coupon, or to
institute suit for the enforcement of any such payment on or after such respective dates shall not
be impaired or affected without the consent of such Holder.

     Section 5.8 Powers and Remedies Cumulative; Delay or Omission Not Waiver of Default.
Except as provided in Section 5.6, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders of Securities or Coupons is intended to be exclusive of any other right
or remedy, and every

24

 

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.

     No delay or omission of the Trustee or of any Holder of Securities or Coupons to exercise any
right or power accruing upon any Event of Default occurring and continuing as aforesaid shall
impair any such right or power or shall be construed to be a waiver of any such Event of Default or
an acquiescence therein; and, subject to Section 5.6, every power and remedy given by this
Indenture or by law to the Trustee or to the Holders of Securities or Coupons may be exercised from
time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders of
Securities or Coupons.

     Section 5.9 Control by Holders of Securities. The Holders of a majority in aggregate
principal amount of the Securities of each series affected (with all such series voting as a single
class) at the time Outstanding 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 by this Indenture; provided
that such direction shall not be otherwise than in accordance with law and the provisions of this
Indenture; provided further that (subject to the provisions of Section 6.1) the Trustee shall have
the right to decline to follow any such direction if the Trustee, being advised by counsel, shall
determine that the action or proceeding so directed may not lawfully be taken or if the Trustee in
good faith by its board of directors, the executive committee, or a trust committee of directors or
Responsible Officers of the Trustee shall determine that the action or proceedings so directed
would involve the Trustee in personal liability or if the Trustee in good faith shall so determine
that the actions or forbearances specified in or pursuant to such direction would be unduly
prejudicial to the interests of Holders of the Securities of all series so affected not joining in
the giving of said direction, it being understood that (subject to Section 6.1) the Trustee shall
have no duty to ascertain whether or not such actions or forbearances are unduly prejudicial to
such Holders.

     Nothing in this Indenture shall impair the right of the Trustee in its discretion to take any
action deemed proper by the Trustee and which is not inconsistent with such direction or directions
by Securityholders.

     Section 5.10 Waiver of Past Defaults. Prior to the acceleration of the maturity of
any Securities as provided in Section 5.1, the Holders of a majority in aggregate principal amount
of the Securities of all series at the time Outstanding with respect to which an Event of Default
shall have occurred and be continuing (voting as a single class) may on behalf of the Holders of
all such Securities waive any past default or Event of Default described in Section 5.1 and its
consequences, except a default in respect of a covenant or provision hereof which cannot be
modified or amended without the consent of the Holder of each Security affected. In the case of
any such waiver, the Issuer, the Trustee and the Holders of all such Securities shall be restored
to their former positions and rights hereunder, respectively; but no such waiver shall extend to
any subsequent or other default or impair any right consequent thereon.

     Upon any such waiver, such default shall cease to exist and be deemed to have been cured and
not to have occurred, and any Event of Default arising therefrom shall be deemed to have been
cured, and not to have occurred for every purpose of this Indenture; but no such waiver shall
extend to any subsequent or other default or Event of Default or impair any right consequent
thereon.

     Section 5.11 Trustee to Give Notice of Default, but May Withhold in Certain
Circumstances. The Trustee shall, within ninety days after the occurrence of a default with
respect to the Securities of any series, give notice of all defaults with respect to that series
actually known to a Responsible Officer of the Trustee (1) if any Unregistered Securities of that
series are then Outstanding, to the Holders thereof, by publication at least once in an Authorized
Newspaper in the Borough of Manhattan, The City of New York and at least once in an Authorized
Newspaper in London (and, if required by Section 3.10, at least once in an Authorized Newspaper in
Luxembourg) and (2) to all Holders of Securities of such series in the manner and to the extent
provided in Section 313(c) of the Trust Indenture Act of 1939, unless in each case such defaults
shall have been cured before the mailing or publication of such notice (the term “defaults” for the

25

 

purpose of this Section being hereby defined to mean any event or condition which is, or with
notice or lapse of time or both would become, an Event of Default); provided that, except in the
case of default in the payment of the principal of or interest on any of the Securities of such
series, or in the payment of any sinking fund installment on such series, the Trustee shall be
protected in withholding such notice if and so long as the board of directors, the executive
committee, or a trust committee of directors or trustees and/or Responsible Officers of the Trustee
in good faith determines that the withholding of such notice is in the interests of the
Securityholders of such series.

     Section 5.12 Right of Court to Require Filing of Undertaking to Pay Costs. All
parties to this Indenture agree, and each Holder of any Security or Coupon by his or her acceptance
thereof shall be deemed to have agreed, that any court may in its discretion require, 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, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any
party litigant in such suit, having due regard to the merits and good faith of the claims or
defenses made by such party litigant; but the provisions of this Section shall not be deemed to
authorize any court to require such an undertaking or to make such an assessment in any suit
instituted by the Issuer.

ARTICLE 6

CONCERNING THE TRUSTEE

     Section 6.1 Duties and Responsibilities of the Trustee; During Default; Prior to
Default. (a) With respect to any series of Securities issued hereunder, the Trustee, prior to
the occurrence of an Event of Default with respect to the Securities of a particular series and
after the curing or waiving of all Events of Default which may have occurred with respect to such
series, undertakes to perform such duties and only such duties as are specifically set forth in
this Indenture with respect to such series and no implied covenants or obligations shall be read
into this Indenture against the Trustee. In case an Event of Default with respect to the
Securities of a series has occurred (which has not been cured or waived) the Trustee shall exercise
with respect to such series of Securities such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a prudent person would
exercise or use under the circumstances in the conduct of his or her own affairs.

     (b) No provision of this Indenture shall be construed to relieve the Trustee from liability
for its own negligent action, its own negligent failure to act or its own willful misconduct,
except that

          (i) prior to the occurrence of an Event of Default with respect to the Securities of any
series and after the curing or waiving of all such Events of Default with respect to such series
which may have occurred:

               (1) the duties and obligations of the Trustee with respect to the Securities of any series
shall be determined solely by the express provisions of this Indenture, and the Trustee shall not
be liable except for the performance of such duties and obligations as are specifically set forth
in this Indenture, and no implied covenants or obligations shall be read into this Indenture
against the Trustee; and

               (2) in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely,
as to the truth of the statements and the correctness of the opinions expressed therein, upon any
statements, certificates or opinions furnished to the Trustee and conforming to the requirements of
this Indenture; but in the case of any such statements, certificates or opinions which by any
provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be
under a duty to examine the same to determine whether or not they conform to the requirements of
this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or
other facts stated therein, unless specifically required by this Indenture);

26

 

          (ii) the Trustee shall not be liable for any error of judgment made in good faith by a
Responsible Officer or Responsible Officers of the Trustee, unless it shall be proved that the
Trustee was negligent in ascertaining the pertinent facts;

          (iii) the Trustee shall not be liable with respect to any action taken or omitted to be taken
by it in good faith in accordance with the direction of the Holders pursuant to Section 5.9
relating to the time, method and place of conducting any proceeding for any remedy available to the
Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture; and

          (iv) the Trustee shall not be required to take notice, and shall not be deemed to have notice,
of any default or Event of Default hereunder, except, if the Trustee is at the time acting as
paying agent in respect of the applicable series of Securities, Events of Default described in
paragraphs (1), (2) and (3) of Section 5.1 hereof, unless a Responsible Officer of the Trustee
shall be notified specifically of the default or Event of Default on a written instrument or
document delivered to it at its notice address by the Issuer or by the Holders of at least 10% of
the aggregate principal amount of Securities then outstanding. In the absence of delivery of
notice satisfying those requirements, the Trustee may assume conclusively that there is no default
or Event of Default, except as otherwise noted herein.

     (c) None of the provisions contained in this Indenture shall require the Trustee to expend or
risk its own funds or otherwise incur financial liability in the performance of any of its duties
or in the exercise of any of its rights or powers, if it shall have reasonable grounds for
believing that the repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

     The provisions of this Section 6.1 are in furtherance of and subject to Section 315 of the
Trust Indenture Act of 1939. 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 6.1.

     Section 6.2 Certain Rights of the Trustee. In furtherance of and subject to the Trust
Indenture Act of 1939, and subject to Section 6.1:

     (a) the Trustee may conclusively rely, as to the truth of the statements and the correctness
of the opinions expressed therein, and shall be protected in acting or refraining from acting upon
any resolution, Officer’s Certificate or any other certificate, statement, instrument, opinion,
report, notice, request, consent, order, bond, debenture, note, coupon, security or other paper or
document believed by it to be genuine and to have been signed or presented by the proper party or
parties;

     (b) any request, direction, order or demand of the Issuer mentioned herein shall be
sufficiently evidenced by an Issuer Order (unless other evidence in respect thereof be herein
specifically prescribed); and any resolution of the Board of Directors may be evidenced to the
Trustee by a Board Resolution;

     (c) the Trustee may consult with legal counsel of its choice, and the advice of such counsel
or any Opinion of Counsel shall be full and complete authorization and protection in respect of any
action taken, suffered or omitted to be taken by it hereunder in good faith and reliance thereon;

     (d) the Trustee shall be under no obligation to exercise any of the trusts or powers vested in
it by this Indenture at the request, order or direction of any of the Securityholders pursuant to
the provisions of this Indenture, unless such Securityholders shall have offered to the Trustee
security or indemnity reasonably satisfactory to the Trustee against the costs, expenses and
liabilities which might be incurred therein or thereby;

     (e) the Trustee shall not be liable for any action taken or omitted by it in good faith and
believed by it to be authorized or within the discretion, rights or powers conferred upon it by
this Indenture;

27

 

     (f) [Reserved];

     (g) 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 such agent or attorney appointed
with due care by it hereunder;

     (h) the rights, privileges, protections, immunities and benefits given to the Trustee,
including, without limitation, its right to be indemnified, are extended to, and shall be
enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and
other Person employed to act hereunder;

     (i) the Trustee may request that the Issuer deliver an Officer’s Certificate setting forth the
names of individuals and/or titles of officers authorized at such time to take specified actions
pursuant to this Indenture, which Officer’s Certificate may be signed by any person authorized to
sign an Officer’s Certificate, including any person specified as so authorized in any such
certificate previously delivered and not superseded;

     (j) 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 Issuer, at a
time reasonably determined by the Issuer, personally or by agent or attorney at the sole cost of
the Issuer and shall incur no liability or additional liability of any kind by reason of such
inquiry or investigation;

     (k) 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, conclusively rely upon an Officer’s Certificate;

     (l) anything in this Indenture notwithstanding, in no event shall the Trustee be liable for
special, indirect, punitive or consequential loss or damage of any kind whatsoever (including but
not limited to loss of profit), even if the Trustee has been advised as to the likelihood of such
loss or damage and regardless of the form of action; and

     (m) the Trustee shall not be responsible or liable for any failure or delay in the performance
of its obligations under this Indenture arising out of or caused, directly or indirectly, by
circumstances beyond its control, including, without limitation, acts of God; earthquakes; fire;
flood; terrorism; wars and other military disturbances; sabotage; epidemics; riots; interruptions;
loss or malfunctions of utilities; computer (hardware or software) or communication services;
accidents; labor disputes; acts of civil or military authority and governmental action.

     Section 6.3 Trustee Not Responsible for Recitals, Disposition of Securities or Application
of Proceeds Thereof. The recitals contained herein and in the Securities or Coupons, except
the Trustee’s certificates of authentication, shall be taken as the statements of the Issuer, and
the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no
representation as to the validity or sufficiency of this Indenture or of any Securities or Coupons.
The Trustee shall not be accountable for the use or application by the Issuer of any of the
Securities or of the proceeds thereof.

     Section 6.4 Trustee and Agents May Hold Securities or Coupons; Collections, Etc. The
Trustee or any agent of the Issuer or the Trustee, in its individual or any other capacity, may
become the owner or pledgee of Securities or Coupons with the same rights it would have if it were
not the Trustee or such agent and may otherwise deal with the Issuer and receive, collect, hold and
retain collections from the Issuer with the same rights it would have if it were not the Trustee or
such agent.

     Section 6.5 Monies Held by Trustee. Subject to the provisions of Section 3.3 hereof,
all monies received by the Trustee shall, until used or applied as herein provided, be held in
trust for the purposes for which they were received, but need not be segregated from other funds
except to the extent required by mandatory provisions of law. Neither the Trustee nor any agent of
the Issuer or the Trustee shall be under any liability for interest on any monies received by it
hereunder.

     Section 6.6 Compensation and Indemnification of Trustee and its Prior Claim. The
Issuer covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be
entitled to, such compensation as shall be agreed in writing between the Issuer and the Trustee
from time to time (which shall not be limited by any provision of law in regard to the compensation
of a trustee of an express trust) and the Issuer covenants and agrees to pay or reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made
by or on behalf of the Trustee accordance with any of the provisions of this Indenture (including
the reasonable compensation and the expenses and disbursements of its counsel and of all agents and
other persons not regularly in its employ) except any such expense, disbursement or advance as may
arise from its negligence, bad faith or willful misconduct. The Issuer also covenants to indemnify
the Trustee and its directors, officers, employees, and agents (the “indemnitees”) for, and to hold
the indemnitees harmless against, any and all loss, liability, claim, damage, penalty, fine or
expense, including reasonable out-of-pocket expenses, reasonable incidental expenses and reasonable
legal fees and expenses incurred without negligence, bad faith or willful misconduct on the
indemnitees’ part, arising out of or in connection with the acceptance or administration of this
Indenture or the trusts hereunder and the indemnitees’ duties hereunder, including the costs and
expenses of defending themselves against or investigating any claim, whether asserted by the Issuer
or any Holder or any other Person, or liability in connection with the exercise or performance of
the indemnitees’ duties or obligations hereunder. The obligations of the Issuer under this Section
to compensate and indemnify the indemnitees and to pay or reimburse the indemnitees for expenses,
disbursements and advances shall constitute additional indebtedness hereunder and shall survive the
satisfaction and discharge of this Indenture. Such additional indebtedness shall be a senior claim
to that of the Securities upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the benefit of the Holders of particular Securities or Coupons, and
the Securities are hereby subordinated to such senior claim.

     When the Trustee incurs expenses or renders services in connection with an Event of Default
specified in Section 5.1(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.
For purposes of this Section 6.6, the term “Trustee” shall also include any predecessor Trustee.

     Section 6.7 [Reserved]

     Section 6.8 Indentures Not Creating Potential Conflicting Interests for the Trustee.
The following indentures are hereby specifically described for the purposes of Section 310(b)(1) of
the Trust Indenture Act of 1939: this Indenture with respect to the Securities of any series.

     Section 6.9 Persons Eligible for Appointment as Trustee. The Trustee for each series
of Securities hereunder shall at all times be a corporation or banking association organized and
doing business under the laws of the United States of America or of any State or the District of
Columbia having a combined capital and surplus of at least $50,000,000, and which is authorized
under such laws to exercise corporate trust powers and is subject to supervision or examination by
Federal, State or District of Columbia authority. Such corporation or banking association shall
have a place of business or an affiliate with a place of business in the Borough of Manhattan, The
City of New York if there be such a corporation or association in such location willing to act upon
reasonable and customary terms and conditions. If such corporation or association publishes
reports of condition at least annually, pursuant to law or to the requirements of the aforesaid
supervising or examining authority, then for the purposes of this Section, the combined capital and
surplus of such corporation or association shall be deemed to be its combined capital and surplus
as set forth in its most recent report of condition so published. In case at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, the Trustee shall
resign immediately in the manner and with the effect specified in Section 6.10.

29

 

     The provisions of this Section 6.9 are in furtherance of and subject to Section 310(a) of the
Trust Indenture Act of 1939.

     Section 6.10 Resignation and Removal; Appointment of Successor Trustee. (a) The
Trustee, or any trustee or trustees hereafter appointed, may at any time resign with respect to one
or more or all series of Securities by giving written notice of
resignation to the Issuer and (i)
if any Unregistered Securities of a series affected are then Outstanding, by giving notice of such
resignation to the Holders thereof, by publication, at the Issuer’s expense, at least once in an
Authorized Newspaper in the Borough of Manhattan, The City of New York, and at least once in an
Authorized Newspaper in London (and, if required by Section 3.10, at least once in an Authorized
Newspaper in Luxembourg), (ii) if any Unregistered Securities of a series affected are then
Outstanding, by mailing notice of such resignation to the Holders thereof who have filed their
names and addresses with the Trustee pursuant to Section 313(c)(2) of the Trust Indenture Act of
1939 at such addresses as were so furnished to the Trustee and (iii) by mailing notice of such
resignation to the Holders of then Outstanding Registered Securities of each series affected at
their addresses as they shall appear on the registry books. Upon receiving such notice of
resignation, the Issuer shall promptly appoint a successor Trustee or Trustees with respect to the
applicable series by written instrument in duplicate, executed by authority of the Board of
Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to
the successor Trustee or Trustees. If no successor Trustee shall have been so appointed with
respect to any series and have accepted appointment within 30 days after the mailing of such notice
of resignation, the resigning Trustee may petition, at the Issuer’s expense, any court of competent
jurisdiction for the appointment of a successor Trustee, or any Securityholder who has been a bona
fide Holder of a Security or Securities of the applicable series for at least six months may,
subject to the provisions of Section 5.12, on behalf of himself or herself and all others similarly
situated, petition any such court for the appointment of a successor Trustee. Such court may
thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor
Trustee.

     (b) In case at any time any of the following shall occur:

          (i) the Trustee shall fail to comply with the provisions of Section 310(b) of the Trust
Indenture Act of 1939 with respect to any series of Securities after written request therefor by
the Issuer or by any Securityholder who has been a bona fide Holder of a Security or Securities of
such series for at least six months; or

          (ii) the Trustee shall cease to be eligible in accordance with the provisions of Section 6.9
and Section 310(a) of the Trust Indenture Act of 1939 and shall fail to resign after written
request therefor by the Issuer or by any Securityholder; or

          (iii) the Trustee shall become incapable of acting with respect to any series of Securities,
or shall be adjudged bankrupt or insolvent, or a receiver or liquidator 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, the Issuer may remove the Trustee with respect to the applicable series of
Securities and appoint a successor Trustee for such series by written instrument, in duplicate,
executed by order of the Board of Directors of the Issuer, one copy of which instrument shall be
delivered to the Trustee so removed and one copy to the successor Trustee, or, subject to the
provisions of Section 315(e) of the Trust Indenture Act of 1939, any Securityholder who has been a
bona fide Holder of a Security or Securities of such series for at least six months may on behalf
of himself or herself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor Trustee with respect
to such series. Such court may thereupon, after such notice, if any, as it may deem proper, remove
the Trustee and appoint a successor Trustee.

     (c) The Holders of a majority in aggregate principal amount of the Securities of each series
at the time Outstanding may at any time remove the Trustee with respect to Securities of such
series and appoint a successor Trustee with respect to the Securities of such series by delivering
to the Trustee so

30

 

removed, to the successor Trustee so appointed and to the Issuer the evidence provided for in
Section 7.1 of the action in that regard taken by such Securityholders.

     (d) Any resignation or removal of the Trustee with respect to any series and any appointment
of a successor Trustee with respect to such series pursuant to any of the provisions of this
Section 6.10 shall become effective upon acceptance of appointment by the successor Trustee as
provided in Section 6.11.

     Section 6.11 Acceptance of Appointment by Successor Trustee. Any successor Trustee
appointed as provided in Section 6.10 shall execute and deliver to the Issuer and to the retiring
Trustee an instrument accepting such appointment hereunder, and thereupon the resignation or
removal of the retiring Trustee with respect to all or any applicable series shall become effective
and such successor Trustee, without any further act, deed or conveyance, shall become vested with
all rights, powers, duties and obligations with respect to such series of its predecessor
hereunder, with like effect as if originally named as Trustee for such series hereunder; but,
nevertheless, on the written request of the Issuer or of the successor Trustee, upon payment of its
charges then unpaid, the Trustee ceasing to act shall, subject to Section 3.3, pay over to the
successor Trustee all monies at the time held by it hereunder and shall execute and deliver an
instrument transferring to such successor trustee all such rights, powers, duties and obligations.
Upon request of any such successor Trustee, the Issuer shall execute any and all instruments in
writing for more fully and certainly vesting in and confirming to such successor Trustee all such
rights and powers. Any Trustee ceasing to act shall, nevertheless, retain a prior claim upon all
property or funds held or collected by such Trustee to secure any amounts then due it pursuant to
the provisions of Section 6.6.

     If a successor Trustee is appointed with respect to the Securities of one or more (but not
all) series, the Issuer, the retiring Trustee and each successor Trustee with respect to the
Securities of any applicable series shall execute and deliver an indenture supplemental hereto
which 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 any
series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring
Trustee, and 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 under separate indentures.

     No successor Trustee with respect to any series of Securities shall accept appointment as
provided in this Section 6.11 unless at the time of such acceptance such successor Trustee shall be
qualified under Section 310(b) of the Trust Indenture Act of 1939 and eligible under the provisions
of Section 6.9.

     Upon acceptance of appointment by any successor Trustee as provided in this Section 6.11, the
Issuer shall give notice thereof (1) if any Unregistered Securities of a series affected are then
Outstanding, to the Holders thereof, by publication of such notice at least once in an Authorized
Newspaper in the Borough of Manhattan, The City of New York, and at least once in an Authorized
Newspaper in London (and, if required by Section 3.10, at least once in an Authorized Newspaper in
Luxembourg) and (2) if any Unregistered Securities of a series affected are then Outstanding, to
the Holders thereof who have filed their names and addresses with the Trustee pursuant to Section
313(c)(2) of the Trust Indenture Act of 1939, by mailing such notice to such Holders at such
addresses as were so furnished to the Trustee (and the Trustee shall make such information
available to the Issuer for such purpose) and (3) if any Registered Securities of a series affected
are then Outstanding, to the Holders thereof, by mailing such notice to such Holders at their
addresses as they shall appear on the registry books. If the acceptance of appointment is
substantially contemporaneous with the resignation, then the notice called for by the preceding
sentence may be combined with the notice called for by Section 6.10. If the Issuer fails to give
such notice within ten days after acceptance of appointment by the successor Trustee, the successor
Trustee shall cause such notice to be given at the expense of the Issuer.

     Section 6.12 Merger, Conversion, Consolidation or Succession to Business of Trustee.
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

31

 

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 that such corporation
shall be qualified under Section 310(b) of the Trust Indenture Act of 1939 and eligible under the
provisions of Section 6.9, without the execution or filing of any paper or any further act on the
part of any of the parties hereto, anything herein to the contrary notwithstanding.

     In case at the time such successor to the Trustee shall succeed to the trusts created by this
Indenture any of the Securities of any series shall have been authenticated but not delivered, any
such successor to the Trustee may adopt such certificate of authentication and deliver such
Securities so authenticated; and, in case at that time any of the Securities of any series shall
not have been authenticated, any successor to the Trustee may authenticate such Securities either
in the name of any predecessor hereunder or in the name of the successor Trustee; and in all such
cases such certificate shall have the full force which it is anywhere in the Securities of such
series or in this Indenture provided that the certificate of the Trustee shall have; provided, that
the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate
Securities of any series in the name of any predecessor Trustee shall apply only to its successor
or successors by merger, conversion or consolidation.

     Section 6.13 Preferential Collection of Claims Against the Issuer. The Trustee shall
comply with Section 311(a) of the Trust Indenture Act of 1939, excluding any creditor relationship
listed in Section 311(b) of the Trust Indenture Act of 1939. A Trustee who has resigned or been
removed shall be subject to Section 311(a) of the Trust Indenture Act of 1939 to the extent
indicated therein.

     Section 6.14 Appointment of Authenticating Agent. As long as any Securities of a
series remain Outstanding, the Trustee may, by an instrument in writing, appoint with the approval
of the Issuer an authenticating agent (the “Authenticating Agent”) which shall be authorized to act
on behalf of the Trustee to authenticate Securities, including Securities issued upon exchange,
registration of transfer, partial redemption or pursuant to Section 2.9. Securities of each such
series authenticated by such Authenticating Agent shall be entitled to the benefits of this
Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee.
Whenever reference is made in this Indenture to the authentication and delivery of Securities of
any series by the Trustee or to 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 for such series and a Certificate of Authentication executed on behalf of the Trustee by such
Authenticating Agent. Such Authenticating Agent shall at all times be a corporation organized and
doing business under the laws of the United States of America or of any State, authorized under
such laws to exercise corporate trust powers, having a combined capital and surplus of at least
$50,000,000 (determined as provided in Section 6.9 with respect to the Trustee) and subject to
supervision or examination by Federal or State authority.

     Any corporation into which any Authenticating Agent may be merged or converted, or with which
it may be consolidated, or any corporation resulting from any merger or conversion or consolidation
to which any Authenticating Agent shall be a party, or any corporation succeeding to all or
substantially all the corporate agency business of any Authenticating Agent, shall continue to be
the Authenticating Agent with respect to all series of Securities for which it served as
Authenticating Agent without the execution or filing of any paper or any further act on the part of
the Trustee or such Authenticating Agent. Any Authenticating Agent may at any time, and if it
shall cease to be eligible shall, resign by giving written notice of resignation to the Trustee and
to the Issuer.

     Upon receiving such a notice of resignation or upon such a termination, or in case at any time
any Authenticating Agent shall cease to be eligible in accordance with the provisions of this
Section 6.14 with respect to one or more series of Securities, the Trustee shall upon receipt of an
Issuer Order appoint a successor Authenticating Agent and the Issuer shall provide notice of such
appointment to all Holders of Securities of such series in the manner and to the extent provided in
Section 11.4. Any successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all rights, powers, duties and responsibilities of its predecessor
hereunder, with like effect as if originally named as Authenticating Agent. The Trustee agrees to
pay to the Authenticating Agent for such series from time to

32

 

time reasonable compensation. The Authenticating Agent for the Securities of any series shall
have no responsibility or liability for any action taken by it as such at the direction of the
Trustee.

     Sections 6.2, 6.3, 6.4, 6.6 and 7.3 shall be applicable to any Authenticating Agent.

ARTICLE 7

CONCERNING THE SECURITYHOLDERS

     Section 7.1 Evidence of Action Taken by Securityholders. Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by this Indenture to be
given or taken by a specified percentage in principal amount of the Securityholders of any or all
series may be embodied in and evidenced by one or more instruments of substantially similar tenor
signed by such specified percentage of Securityholders in person or by 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. Proof of execution of any
instrument or of a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Sections 6.1 and 6.2) conclusive in favor of the Trustee and the Issuer,
if made in the manner provided in this Article.

     Section 7.2 Proof of Execution of Instruments and of Holding of Securities. Subject
to Sections 6.1 and 6.2, the execution of any instrument by a Securityholder or his or her agent or
proxy may be proved in the following manner:

     (a) The fact and date of the execution by any Holder of any instrument may be proved by the
certificate of any notary public or other officer of any jurisdiction authorized to take
acknowledgments of deeds or administer oaths that the person executing such instruments
acknowledged to him or her the execution thereof, or by an affidavit of a witness to such execution
sworn to before any such notary or other such officer. Where such execution is by or on behalf of
any legal entity other than an individual, such certificate or affidavit shall also constitute
sufficient proof of the authority of the person executing the same.

     (b) The fact of the holding by any Holder of an Unregistered Security of any series, and the
identifying number of such Security and the date of his or her holding the same, may be proved by
the production of such Security or by a certificate executed by any trust company, bank, banker or
recognized securities dealer wherever situated satisfactory to the Trustee, if such certificate
shall be deemed by the Trustee to be satisfactory. Each such certificate shall be dated and shall
state that on the date thereof a Security of such series bearing a specified identifying number was
deposited with or exhibited to such trust company, bank, banker or recognized securities dealer by
the person named in such certificate. Any such certificate may be issued in respect of one or more
Unregistered Securities of one or more series specified therein. The holding by the person named
in any such certificate of any Unregistered Securities of any series specified therein shall be
presumed to continue for a period of one year from the date of such certificate unless at the time
of any determination of such holding (i) another certificate bearing a later date issued in respect
of the same Securities shall be produced, or (ii) the Securities of such series specified in such
certificate shall be produced by some other person, or (iii) the Securities of such series specified
in such certificate shall have ceased to be Outstanding. Subject to Sections 6.1 and 6.2, the fact
and date of the execution of any such instrument and the amount and numbers of Securities of any
series held by the person so executing such instrument and the amount and numbers of any Security
or Securities for such series may also be proven in accordance with such reasonable rules and
regulations as may be prescribed by the Trustee for such series or in any other manner which the
Trustee for such series may deem sufficient.

     (c) In the case of Registered Securities, the ownership of such Securities shall be proved by
the Security register or by a certificate of the Security registrar.

     The Issuer may set a record date for purposes of determining the identity of Holders of
Registered Securities of any series entitled to vote or consent to any action referred to in
Section 7.1, which record date

33

 

may be set at any time or from time to time by notice to the Trustee, for any date or dates
(in the case of any adjournment or reconsideration) not more than 60 days nor less than five days
prior to the proposed date of such vote or consent, and thereafter, notwithstanding any other
provisions hereof, with respect to Registered Securities of any series, only Holders of Registered
Securities of such series of record on such record date shall be entitled to so vote or give such
consent or revoke such vote or consent.

     Section 7.3 Holders to Be Treated as Owners. The Issuer, the Trustee and any agent of
the Issuer or the Trustee may deem and treat the person in whose name any Security shall be
registered upon the Security register for such series as the absolute owner of such Security
(whether or not such Security shall be overdue and notwithstanding any notation of ownership or
other writing thereon) for the purpose of receiving payment of or on account of the principal of
and, subject to the provisions of this Indenture, interest on such Security and for all other
purposes; and neither the Issuer nor the Trustee nor any agent of the Issuer or the Trustee shall
be affected by any notice to the contrary. The Issuer, the Trustee and any agent of the Issuer or
the Trustee may treat the Holder of any Unregistered Security and the Holder of any Coupon as the
absolute owner of such Unregistered Security or Coupon (whether or not such Unregistered Security
or Coupon shall be overdue) for the purpose of receiving payment thereof or on account thereof and
for all other purposes and neither the Issuer, the Trustee, nor any agent of the Issuer or the
Trustee shall be affected by any notice to the contrary. All such payments so made to any such
person, or upon his or her order, shall be valid, and, to the extent of the sum or sums so paid,
effectual to satisfy and discharge the liability for monies payable upon any such Unregistered
Security or Coupon.

     Section 7.4 Securities Owned by Issuer Deemed Not Outstanding. In determining whether
the Holders of the requisite aggregate principal amount of Outstanding Securities of any or all
series have concurred in any direction, consent or waiver under this Indenture, Securities which
are owned by the Issuer or any other obligor on the Securities with respect to which such
determination is being made or by any person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Issuer or any other obligor on the Securities with
respect to which such determination is being made shall be disregarded and deemed not to be
Outstanding for the purpose of any such determination, except that for the purpose of determining
whether the Trustee shall be protected in relying on any such direction, consent or waiver only
Securities which a Responsible Officer of the Trustee actually knows are so owned shall be so
disregarded. Securities so owned which have been pledged in good faith may be regarded as
Outstanding if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to
act with respect to such Securities and that the pledgee is not the Issuer or any other obligor
upon the Securities or any person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Issuer or any other obligor on the Securities. In case
of a dispute as to such right, the advice of counsel shall be full protection in respect of any
decision made by the Trustee in accordance with such advice. Upon request of the Trustee, the
Issuer shall furnish to the Trustee promptly an Officer’s Certificate listing and identifying all
Securities, if any, known by the Issuer to be owned or held by or for the account of any of the
above-described Persons; and, subject to Sections 6.1 and 6.2, the Trustee shall be entitled to
accept such Officer’s Certificate as conclusive evidence of the facts therein set forth and of the
fact that all Securities not listed therein are Outstanding for the purpose of any such
determination.

     Section 7.5 Right of Revocation of Action Taken. At any time prior to (but not after)
the evidencing to the Trustee, as provided in Section 7.1, of the taking of any action by the
Holders of the percentage in aggregate principal amount of the Securities of any or all series, as
the case may be, specified in this Indenture in connection with such action, any Holder of a
Security the serial number of which is shown by the evidence to be included among the serial
numbers of the Securities the Holders of which have consented to such action may, by filing written
notice at the Corporate Trust Office and upon proof of holding as provided in this Article, revoke
such action so far as concerns such Security. Except as aforesaid any such action taken by the
Holder of any Security shall be conclusive and binding upon such Holder and upon all future Holders
and owners of such Security and of any Securities issued in exchange or substitution therefor or on
registration of transfer thereof, irrespective of whether or not any notation in regard thereto is
made upon any such Security. Any action taken by the Holders of the percentage in aggregate
principal amount of the Securities of any or all series, as the case may be, specified in this
Indenture in connection with such action shall be conclusively binding upon the Issuer, the Trustee
and the Holders of all the Securities affected by such action.

ARTICLE 8

SUPPLEMENTAL INDENTURES

     Section 8.1 Supplemental Indentures Without Consent of Securityholders. (a) In
addition to any supplemental indenture otherwise authorized by this Indenture, the Issuer, when
authorized by a resolution of its Board of Directors (which resolution may provide general terms or
parameters for such action and may provide that the specific terms of such action may be determined
in accordance with or pursuant to an Issuer Order), and the Trustee may from time to time and at
any time enter into an indenture or indentures supplemental hereto, which comply with the Trust
Indenture Act of 1939, as then in effect, without the consent of the Holders, for one or more of
the following purposes:

          (i) to convey, transfer, assign, mortgage or pledge to the Trustee as security for the
Securities of one or more series any property or assets;

          (ii) to evidence the succession of another Person to the Issuer, or successive successions,
and the assumption by the successor Person of the covenants, agreements and obligations of the
Issuer pursuant to Article 9;

          (iii) to add to the covenants of the Issuer such further covenants, restrictions, conditions
or provisions as the Issuer and the Trustee shall consider to be for the protection of the Holders
of Securities or Coupons, and to make the occurrence, or the occurrence and continuance, of a
default in any such additional covenants, restrictions, conditions or provisions an Event of
Default permitting the enforcement of all or any of the several remedies provided in this Indenture
as herein set forth; provided, that in respect of any such additional covenant, restriction,
condition or provision such supplemental indenture may provide for a particular period of grace
after default (which period may be shorter or longer than that allowed in the case of other
defaults) or may provide for an immediate enforcement upon such an Event of Default or may limit
the remedies available to the Trustee upon such an Event of Default or may limit the right of the
Holders of a majority in aggregate principal amount of the Securities of such series to waive such
an Event of Default;

          (iv) to cure any ambiguity or to correct or supplement any provision contained herein or in
any supplemental indenture which may be defective or inconsistent with any other provision
contained herein or in any supplemental indenture, or to make any other provisions as the Issuer
may deem necessary or desirable, provided that no such action shall adversely affect the interests
of the Holders of the Securities or Coupons;

          (v) to establish the forms or terms of Securities of any series or of the Coupons appertaining
to such Securities as permitted by Sections 2.1 and 2.3; and

          (vi) to evidence and provide for the acceptance of appointment hereunder by a successor
Trustee with respect to the Securities of one or more series and to 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, pursuant to the requirements of Section 6.11.

     (b) The Trustee is hereby authorized to join with the Issuer in the execution of any such
supplemental indenture, to make any further appropriate agreements and stipulations which may be
therein contained and to accept the conveyance, transfer, assignment, mortgage or pledge of any
property thereunder, but the Trustee shall not be obligated to enter into any such supplemental
indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or
otherwise.

     (c) Any supplemental indenture authorized by the provisions of this Section may be executed
without the consent of the Holders of any of the Securities at the time outstanding,
notwithstanding any of the provisions of Section 8.2.

35

 

     Section 8.2 Supplemental Indentures With Consent of Securityholders. (a) With the
consent (evidenced as provided in Article VII) of the Holders of not less than a majority in
aggregate principal amount of the Securities at the time Outstanding of all series affected by such
supplemental indenture (voting as one class), the Issuer, when authorized by a resolution of its
Board of Directors (which resolution may provide general terms or parameters for such action and
may provide that the specific terms of such action may be determined in accordance with or pursuant
to an Issuer Order), and the Trustee may, from time to time and at any time, enter into an
indenture or indentures supplemental hereto, which comply with the Trust Indenture Act of 1939, as
then in effect, for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Indenture or of any supplemental indenture or of
modifying in any manner the rights of the Holders of the Securities of each such series or of the
Coupons appertaining to such Securities; provided, that no such
supplemental indenture shall (i)
extend the final maturity of any then issued Security, or reduce the principal amount thereof, or
reduce the rate or extend the time of payment of interest thereon, or reduce any amount payable on
redemption thereof, or make the principal thereof (including any amount in respect of original
issue discount), or interest thereon payable in any coin or currency other than that provided in
such Securities and any Coupons thereon or in accordance with the terms thereof, or reduce the
amount of the principal of a then issued Original Issue Discount Security that would be due and
payable upon an acceleration of the maturity thereof pursuant to Section 5.1 or the amount thereof
provable in bankruptcy pursuant to Section 5.2, or impair or affect the right of any Securityholder
to institute suit for the payment thereof or, if such Securities provide therefor, any right of
repayment at the option of the Securityholder, in each case without the consent of the Holder of
each Security so affected, or (ii) reduce the percentage in principal amount of then issued
Securities of any series, the consent of the Holders of which is required for any such supplemental
indenture, without the consent of the Holders of each Security so affected.

     (b) 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 Holders of Securities of such series, or of
Coupons appertaining to such Securities, with respect to such covenant or provision, shall be
deemed not to affect the rights under this Indenture of the Holders of Securities of any other
series or of the Coupons appertaining to such Securities.

     (c) Upon the request of the Issuer, accompanied by a copy of a resolution of the Board of
Directors (which resolution may provide general terms or parameters for such action and may provide
that the specific terms of such action may be determined in accordance with or pursuant to an
Issuer Order) certified by the secretary or an assistant secretary of the Issuer authorizing the
execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of
the consent of the Holders of the Securities as aforesaid and other documents, if any, required by
Section 7.1, the Trustee shall join with the Issuer in the execution of such supplemental indenture
unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under
this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be
obligated to, enter into such supplemental indenture.

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

     (e) Promptly after the execution by the Issuer and the Trustee of any supplemental indenture
pursuant to the provisions of this Article, the Issuer shall, or shall cause the Trustee to, give
notice thereof (i) if any Registered Securities of a series affected thereby are then Outstanding,
to the Holders thereof by mailing a notice thereof by first-class mail to such Holders at their
addresses as they shall appear on the Security register, (ii) if any Unregistered Securities of a
series affected thereby are then Outstanding, to the Holders thereof who have filed their names and
addresses with the Trustee pursuant to Section 313 (c)(2) of the Trust Indenture Act of 1939, by
mailing a notice thereof by first-class mail to such Holders at such addresses as were so furnished
to the Trustee and (iii) if any Unregistered Securities of a series affected thereby are then
Outstanding, to all Holders thereof, by publication of a notice thereof at least once in an
Authorized Newspaper in the Borough of Manhattan, The City of New York, and at least once in an
Authorized Newspaper in London (and, if required by Section 3.10, at least once in an Authorized

36

 

Newspaper in Luxembourg), and, in each case, such notice shall set forth in general terms the
substance of such supplemental indenture. Any failure of the Issuer or the Trustee to give such
notice, or any defect therein, shall not, however, in any way impair or affect the validity of any
such supplemental indenture.

     Section 8.3 Effect of Supplemental Indenture. Upon the execution of any supplemental
indenture pursuant to the provisions hereof, this Indenture shall be and be deemed to be modified
and amended in accordance therewith and the respective rights, limitations of rights, obligations,
duties and immunities under this Indenture of the Trustee, the Issuer and the Holders of Securities
of each series affected thereby shall thereafter be determined, exercised and enforced hereunder
subject in all respects to such modifications and amendments, and all the terms and conditions of
any such supplemental indenture shall be and be deemed to be part of the terms and conditions of
this Indenture for any and all purposes.

     Section 8.4 Documents to Be Given to Trustee. The Trustee, subject to the provisions
of Sections 6.1 and 6.2, shall be entitled to receive, and shall be fully protected in relying
upon, an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any
supplemental indenture executed pursuant to this Article 8 complies with the applicable
provisions of this Indenture.

     Section 8.5 Notation on Securities in Respect of Supplemental Indentures. Securities
of any series authenticated and delivered after the execution of any supplemental indenture
pursuant to the provisions of this Article may bear a notation in form approved by the Trustee for
such series as to any matter provided for by such supplemental indenture or as to any action taken
by Securityholders. If the Issuer or the Trustee shall so determine, new Securities of any series
so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any
modification of this Indenture contained in any such supplemental indenture may be prepared by the
Issuer, authenticated by the Trustee and delivered in exchange for the Securities of such series
then Outstanding.

     Section 8.6 Conformity with Trust Indenture Act of 1939. Every supplemental indenture
executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act of
1939 as then in effect.

consolidate with or merge into another Person or sell, assign, convey, transfer or lease its
properties and assets substantially as an entirety to any Person (other than a direct or indirect
wholly-owned subsidiary of the Issuer), unless:

     (a) either the Issuer is the continuing Person, or the successor Person (if other than the
Issuer) expressly assumes by supplemental indenture the obligations and covenants evidenced by the
Indenture and the Securities (in which case, the Issuer will be discharged therefrom), and

     (b) immediately thereafter, no Event of Default, and no event which after notice or lapse of

exercise every right and power of, the Issuer under this Indenture with the same effect as if such
successor Person had been named as the Issuer herein, and thereafter, except in the case of a
lease, the predecessor Person shall be relieved of all obligations and covenants under this
Indenture and the Securities.

within any series and any Coupons appertaining thereto (except as to any surviving rights of
registration of transfer or exchange of such Securities and replacement of such Securities which
may have been lost, stolen or mutilated as herein expressly provided for) and the Trustee, at the
expense of the Issuer, shall execute proper instruments acknowledging satisfaction and discharge of
this Indenture with respect to such Securities and any Coupons appertaining thereto when

          (i) either

     (1) all such Securities previously authenticated and delivered and all Coupons

Section 2.8, (B) such Securities and Coupons which have been destroyed, lost or
stolen and which have been replaced or paid as provided in Section 2.9, (C) such

provided in Section 12.3 and (D) such Securities and Coupons for whose payment
money has theretofore been deposited in trust or segregated and held in trust by
the Issuer and thereafter repaid to the Issuer or discharged from such trust as
provided in Section 3.3) have been delivered to the Trustee for cancellation; or

     (2) all Securities of such series and, in the case of (X) or (Y) below, all
Coupons appertaining thereto not theretofore delivered to the Trustee for
cancellation (X) have become due and payable, or (Y) will become due and payable
within one year, or (Z) if redeemable at the option of the Issuer, are to be called
for redemption within one year under arrangements satisfactory to the Trustee for
the giving of notice of redemption by the Trustee in the name, and at the expense,
of the Issuer, and the Issuer, in the case of (X), (Y) or (Z) above, has
irrevocably deposited or caused to be deposited with the Trustee as trust funds in
trust for the purpose an amount in the currency or currencies or currency unit or
units in which the Securities of such series are payable, sufficient to pay and
discharge the entire indebtedness on such Securities and such Coupons not
theretofore delivered to the Trustee for cancellation, for principal, premium, if
any, and interest, with respect thereto, to the date of such deposit (in the case
of Securities which have become due and payable) or maturity date or redemption
date, as the case may be;

          (ii) the Issuer has paid or caused to be paid all other sums payable hereunder by the Issuer;
and

          (iii) the Issuer has delivered to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that all conditions precedent herein provided for relating to the
satisfaction and discharge of this Indenture as to such series have been complied with.

     (b) Notwithstanding the satisfaction and discharge of this Indenture, the obligation of the
Issuer to the Trustee under Section 6.6, the obligations of the Trustee to any Authenticating Agent
under Section 6.14 and, if money shall have been deposited with
the Trustee pursuant to (a)(i)(2) of this Section, the obligations of the Trustee under Section 10.2 and the last paragraph of
Section 3.3 shall survive.

38

 

     Section 10.2 Application of Trust Funds. Subject to the provisions of the last
paragraph of Section 3.3, all money deposited with the Trustee pursuant to Section 10.1 shall be
held in trust and applied by it, in accordance with the provisions of the Securities, the Coupons
and this Indenture, to the payment, either directly or through any paying agent (including the
Issuer acting as its own paying agent) as the Trustee may determine, to the Persons entitled
thereto of the principal, premium, if any and any interest for whose payment such money has been
deposited with or received by the Trustee, but such money need not be segregated from other funds
except to the extent required by law.

     Section 10.3 Applicability of Defeasance Provisions; Issuer’s Option to Effect Defeasance
or Covenant Defeasance. If pursuant to Section 2.3 provision is made for either or both of (1)
defeasance of the Securities of or within a series under Section 10.4 or (2) covenant defeasance of
the Securities of or within a series under Section 10.5, then the provisions of such Section or
Sections, as the case may be, together with the provisions of Sections 10.6 through 10.9 inclusive,
with such modifications thereto as may be specified pursuant to Section 2.3 with respect to any
Securities, shall be applicable to such Securities and any Coupons appertaining thereto, and the
Issuer may at its option by or pursuant to Board Resolution, at any time, with respect to such
Securities and any Coupons appertaining thereto, elect to have Section 10.4 (if applicable) or
Section 10.5 (if applicable) be applied to such Outstanding Securities and any Coupons appertaining
thereto upon compliance with the conditions set forth below in this Article.

     Section 10.4 Defeasance and Discharge. Upon the Issuer’s exercise of the option
specified in Section 10.3 applicable to this Section with respect to the Securities of or within a
series, the Issuer shall be deemed to have been discharged from its obligations with respect to
such Securities and any Coupons appertaining thereto on and after the date the conditions set forth
in Section 10.6 are satisfied (hereinafter “defeasance”). For this purpose, such defeasance means
that the Issuer shall be deemed to have paid and discharged the entire indebtedness represented by
such Securities and any Coupons appertaining thereto which shall thereafter be deemed to be
“Outstanding” only for the purposes of Section 10.7 and the other Sections of this Indenture
referred to in clause (2) of this Section, and to have satisfied all its other obligations under
such Securities and any Coupons appertaining thereto and this Indenture insofar as such Securities
and any Coupons appertaining thereto are concerned (and the Trustee, at the expense of the Issuer,
shall on an Issuer Order execute proper instruments acknowledging the same), except the following
which shall survive until otherwise terminated or discharged hereunder: (1) the rights of Holders
of such Securities and any Coupons appertaining thereto to receive, solely from the trust funds
described in Section 10.6(1) and as more fully set forth in such Section, payments in respect of
the principal of, premium, if any, and interest, if any, on such Securities or any Coupons
appertaining thereto when such payments are due; (2) the Issuer’s obligations with respect to such
Securities under Sections 2.8, 2.9, 3.2 and 3.3 and with respect to the payment of additional
amounts, if any, payable with respect to such Securities as specified pursuant to Section 2.3; (3)
the rights, powers, trusts, duties and immunities of the Trustee hereunder and (4) this Article 10.
Subject to compliance with this Article 10, the Issuer may exercise its option under this Section
notwithstanding the prior exercise of its option under Section 10.5 with respect to such Securities
and any Coupons appertaining thereto. Following a defeasance, payment of such Securities may not
be accelerated because of an Event of Default.

     Section 10.5 Covenant Defeasance. Upon the Issuer’s exercise of the option specified
in Section 10.3 applicable to this Section with respect to any Securities of or within a series,
the Issuer shall be released from its obligations under Sections 9.1 and 3.5 through 3.12 inclusive
and, if specified pursuant to Section 2.3, its obligations under any other covenant with respect to
such Securities and any Coupons appertaining thereto on and after the date the conditions set forth
in Section 10.6 are satisfied (hereinafter, “covenant defeasance”), and such Securities and any
Coupons appertaining thereto shall thereafter be deemed to be not “Outstanding” for the purposes of
any direction, waiver, consent or declaration or Act of Holders (and the consequences of any
thereof) in connection with Sections 9.1 and 3.5 through 3.12 inclusive or such other covenant, but
shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such
covenant defeasance means that, with respect to such Securities and any Coupons appertaining
thereto, the Issuer may omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such Section or such other covenant, whether directly or
indirectly, by reason of any reference elsewhere herein to any such Section or such other covenant
or by reason of reference in any such Section or such other covenant to any other provision herein
or in any other

39

 

document and such omission to comply shall not constitute a default or an Event of Default
under Section 5.1(3) or (4) or otherwise, as the case may be, but, except as specified above, the
remainder of this Indenture and such Securities and any Coupons appertaining thereto shall be
unaffected thereby.

     Section 10.6 Conditions to Defeasance or Covenant Defeasance. The following shall be
the conditions to application of Section 10.4 or Section 10.5 to any Securities of or within a
series and any Coupons appertaining thereto:

     (a) The Issuer shall have deposited or caused to be deposited irrevocably with the Trustee (or
another Trustee satisfying the requirements of Section 6.9 who shall agree to comply with, and
shall be entitled to the benefits of, the provisions of Sections 10.3 through 10.9 inclusive and
the last paragraph of Section 3.3 applicable to the Trustee, for purposes of such Sections also a
“Trustee”) as trust funds in trust for the purpose of making the payments referred to in clauses
(X) and (Y) of this Section 10.6(a), specifically pledged as security for, and dedicated solely to,
the benefit of the Holders of such Securities and any Coupons appertaining thereto, with
instructions to the Trustee as to the application thereof, (i) money in an amount (in such
currency, currencies or currency unit or units in which such Securities and any Coupons
appertaining thereto are then specified as payable at maturity), or
(ii) if Securities of such
series are not subject to repayment at the option of Holders, U.S. Government Obligations which
through the payment of interest and principal in respect thereof in accordance with their terms
will provide, not later than one day before the due date of any payment referred to in clause (X)
or (Y) of this Section 10.6(a), money in an amount or (iii) a combination thereof in an amount
sufficient, in the opinion of a nationally recognized firm of independent certified public
accountants expressed in a written certification thereof delivered to the Trustee, to pay and
discharge, and which shall be applied by the Trustee to pay and discharge, (X) the principal of,
premium, if any, and interest, if any, on Securities and any Coupons appertaining thereto on the
maturity of such principal or installment of principal or interest and (Y) any mandatory sinking
fund payments applicable to such Securities on the day on which such payments are due and payable
in accordance with the terms of this Indenture and such Securities and any Coupons appertaining
thereto. Before such a deposit the Issuer may make arrangements satisfactory to the Trustee for
the redemption of Securities at a future date or dates in accordance with Article 12 which shall be
given effect in applying the foregoing.

     (b) Such defeasance or covenant defeasance shall not result in a breach or violation of, or
constitute a default or Event of Default under, this Indenture or result in a breach or violation
of, or constitute a default under, any other material agreement or instrument to which the Issuer
is a party or by which it is bound.

     (c) In the case of an election under Section 10.4, the Issuer shall have delivered to the
Trustee an Officers’ Certificate and an Opinion of Counsel to
the effect that (i) the Issuer has
received from, or there has been published by, the Internal Revenue
Service a ruling, or (ii) since
the date of execution of this Indenture, there has been a change in the applicable Federal income
tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the
Holders of such Securities and any Coupons appertaining thereto will not recognize income, gain or
loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal
income tax on the same amount and in the same manner and at the same times, as would have been the
case if such deposit, defeasance and discharge had not occurred.

     (d) In the case of an election under Section 10.5, the Issuer shall have delivered to the
Trustee an Opinion of Counsel to the effect that the Holders of such Securities and any Coupons
appertaining thereto will not recognize income, gain or loss for Federal income tax purposes as a
result of such covenant defeasance and will be subject to Federal income tax on the same amounts,
in the same manner and at the same times as would have been the case if such covenant defeasance
had not occurred.

     (e) The Issuer shall have delivered to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that all conditions precedent to the defeasance under Section 10.4 or the
covenant defeasance under Section 10.5 (as the case may be), including those contained in this
Section 10.6 other than the 90 day period specified in
Section 10.6(g), have been complied with.

40

 

     (f) This Issuer shall have delivered to the Trustee an Officer’s Certificate to the effect
that neither such Securities nor any other Securities of the same series, if then listed on any
securities exchange, will be delisted as a result of such deposit.

     (g) No event which is, or after notice or lapse of time or both would become, an Event of
Default with respect to such Securities or any other Securities shall have occurred and be
continuing at the time of such deposit or, with regard to any such event specified in Sections
5.1(e) and (f), at any time on or prior to the 90th day after the date of such deposit (it being
understood that this condition shall not be deemed satisfied until after such 90th day).

     (h) Such defeasance or covenant defeasance shall not result in the trust arising from such
deposit constituting an investment company within the meaning of the Investment Company Act of 1940
unless such trust shall be registered under such Act or exempt from registration thereunder.

     (i) Such defeasance or covenant defeasance shall be effected in compliance with any additional
or substitute terms, conditions or limitations which may be imposed on the Issuer in connection
therewith as contemplated by Section 2.3.

     Section 10.7 Deposited Money and U.S. Government Obligations to be Held in Trust.
Subject to the provisions of the last paragraph of Section 3.3, all money and U.S. Government
Obligations (or other property as may be provided pursuant to Section 2.3) (including the proceeds
thereof) deposited with the Trustee pursuant to Section 10.6 in respect of any Securities of any
series and any Coupons appertaining thereto shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities and any Coupons appertaining thereto and this
Indenture, to the payment, either directly or through any paying agent (including the Issuer acting
as its own paying agent) as the Trustee may determine, to the Holders of such Securities and any
Coupons appertaining thereto of all sums due and to become due thereon in respect of principal,
premium, if any, and interest, if any, but such money need not be segregated from other funds
except to the extent required by law.

     Section 10.8 Repayment to Issuer. The Trustee (any paying agent) shall promptly pay
to the Issuer upon Issuer Order any excess money or securities held by them at any time.

     Section 10.9 Indemnity For U.S. Government Obligations. The Issuer shall pay, and
shall indemnify the Trustee against, any tax, fee or other charge imposed on or assessed against
U.S. Government Obligations deposited pursuant to this Article or the principal and interest and
any other amount received on such U.S. Government Obligations.

     Section 10.10 Reimbursement. If the Trustee or the paying agent is unable to apply
any money in accordance with this Article with respect to any Securities by reason of any order or
judgment of any court or government authority enjoining, restraining or otherwise prohibiting such
application, then the obligations under this Indenture and such Securities from which the Issuer
has been discharged or released pursuant to Section 10.4 or 10.5 shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such Securities, until such
time as the Trustee or paying agent is permitted to apply all money held in trust pursuant to
Section 10.7 with respect to such Securities in accordance with this Article; provided, however,
that if the Issuer makes any payment of principal of or any premium or interest on any such
Security following such reinstatement of its obligations, the Issuer 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.

ARTICLE 11

MISCELLANEOUS PROVISIONS

     Section 11.1 Incorporators, Stockholders, Officers and Directors of Issuer Exempt from
Individual Liability. No recourse under or upon any obligation, covenant or agreement
contained in this

41

 

Indenture, or in any Security, or because of any indebtedness evidenced thereby, shall be had
against any incorporator, as such or against any past, present or future stockholder, officer or
director, as such, of the Issuer or of any successor, either directly or through the Issuer or any
successor, under any rule of law, statute or constitutional provision or by the enforcement of any
assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly
waived and released by the acceptance of the Securities and the Coupons appertaining thereto by the
Holders thereof and as part of the consideration for the issue of the Securities and the Coupons
appertaining thereto.

     Section 11.2 Provisions of Indenture for the Sole Benefit of Parties and Holders of
Securities and Coupons. Nothing in this Indenture, in the Securities or in the Coupons
appertaining thereto, expressed or implied, shall give or be construed to give to any person, firm
or corporation, other than the parties hereto and their successors and the Holders of the
Securities or Coupons, if any, any legal or equitable right, remedy or claim under this Indenture
or under any covenant or provision herein contained, all such covenants and provisions being for
the sole benefit of the parties hereto and their successors and of the Holders of the Securities or
Coupons, if any.

     Section 11.3 Successors and Assigns of Issuer Bound by Indenture. All the covenants,
stipulations, promises and agreements in this Indenture contained by or in behalf of the Issuer
shall bind its successors and assigns, whether so expressed or not.

     Section 11.4 Notices and Demands on Issuer, Trustee and Holders of Securities and
Coupons. Any notice or demand which by any provision of this Indenture is required or
permitted to be given or served by the Trustee or by the Holders of Securities or Coupons to or on
the Issuer shall be in writing (which may be by facsimile) and may be given or served by being
deposited postage prepaid, first-class mail (except as otherwise specifically provided herein)
addressed (until another address of the Issuer is filed by the Issuer with the Trustee) to
AMERIGROUP Corporation, 4425 Corporation Lane, Virginia Beach, Virginia 23462, Attention: General
Counsel. Any notice, direction, request or demand by the Issuer or any Holder of Securities or
Coupons to or upon the Trustee shall be sufficient for every purpose hereunder if made, given,
furnished or filed in writing (which may be by facsimile) to or with the Trustee at its Corporate
Trust Office, Attention Corporate Trust Division—Corporate Finance Unit.

     Where this Indenture provides for notice to Holders of Registered Securities, such notice
shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed,
first-class postage prepaid, to each Holder entitled thereto, at his or her last address as it
appears in the Security register. In any case where notice to such Holders is given by mail,
neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular
Holder shall affect the sufficiency of such notice with respect to other Holders. Where this
Indenture provides for notice in any manner, such notice may be waived in writing by the person
entitled to receive such notice, either before or after the event, and such waiver shall be the
equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in reliance upon such
waiver.

     In case, by reason of the suspension of or irregularities in regular mail service, it shall be
impracticable to mail notice to the Issuer when such notice is required to be given pursuant to any
provision of this Indenture, then any manner of giving such notice as shall be reasonably
satisfactory to the Trustee shall be deemed to be a sufficient giving of such notice.

     Section 11.5 Officer’s Certificates and Opinions of Counsel; Statements to Be Contained
Therein. Upon any application, request or demand by the Issuer to the Trustee to take any
action under any of the provisions of this Indenture, the Issuer shall furnish to the Trustee an
Officer’s Certificate stating that all conditions precedent provided for in this Indenture relating
to the proposed action have been complied with and an Opinion of Counsel stating that in the
opinion of such counsel all such conditions precedent have been complied with, except that in the
case of any such application, request or demand as to which the furnishing of such documents is
specifically required by any provision of this Indenture relating to such particular application,
request or demand, no additional certificate or opinion need be furnished.

42

 

     Each certificate or opinion provided for in this Indenture and delivered to the Trustee with
respect to compliance with a condition or covenant provided for in this Indenture shall include (1)
a statement that the person making such certificate or opinion has read such covenant or condition,
(2) a brief statement as to the nature and scope of the examination or investigation upon which the
statements or opinions contained in such certificate or opinion are based, (3) a statement that, in
the opinion of such person, he or she has made such examination or investigation as is necessary to
enable him or her to express an informed opinion as to whether or not such covenant or condition
has been complied with and (4) a statement as to whether or not, in the opinion of such person,
such condition or covenant has been complied with.

     Any certificate, statement or opinion of an officer of the Issuer may be based, insofar as it
relates to legal matters, upon a certificate or opinion of or representations by counsel, unless
such officer knows that the certificate or opinion or representations with respect to the matters
upon which his or her certificate, statement or opinion may be based as aforesaid are erroneous, or
in the exercise of reasonable care should know that the same are erroneous. Any certificate,
statement or opinion of counsel may be based, insofar as it relates to factual matters, information
with respect to which is in the possession of the Issuer, upon the certificate, statement or
opinion of or representations by an officer or officers of the Issuer, unless such counsel actually
knows that the certificate, statement or opinion or representations with respect to the matters
upon which his or her certificate, statement or opinion may be based as aforesaid are erroneous, or
in the exercise of reasonable care should know that the same are erroneous.

     Any certificate, statement or opinion of an officer of the Issuer or of counsel may be based,
insofar as it relates to accounting matters, upon a certificate or opinion of or representations by
an accountant or firm of accountants in the employ of the Issuer, unless such officer or counsel,
as the case may be, knows that the certificate or opinion or representations with respect to the
accounting matters upon which his or her certificate, statement or opinion may be based as
aforesaid are erroneous, or in the exercise of reasonable care should know that the same are
erroneous.

     Any certificate or opinion of any independent firm of public accountants filed with and
directed to the Trustee shall contain a statement that such firm is independent.

     Section 11.6 Payments Due on Saturdays, Sundays and Holidays. If the date of maturity
of interest on or principal of the Securities of any series or any Coupons appertaining thereto or
the date fixed for redemption or repayment of any such Security or Coupon shall not be a Business
Day, then payment of interest or principal need not be made on such date, but may be made on the
next succeeding Business Day with the same force and effect as if made on the date of maturity or
the date fixed for redemption, and no interest shall accrue for the period after such date.

     Section 11.7 Conflict of Any Provision of Indenture with Trust Indenture Act of 1939.
If and to the extent that any provision of this Indenture limits, qualifies or conflicts with the
duties imposed by, or with another provision (an “incorporated provision”) included in this
Indenture by operation of, Sections 310 to 318, inclusive, of the Trust Indenture Act of 1939, such
imposed duties or incorporated provision shall control.

     Section 11.8 New York Law to Govern; Waiver of Jury Trial. This Indenture and each
Security and Coupon shall be deemed to be a contract under the laws of the State of New York, and
for all purposes shall be construed in accordance with the laws of such State.

     EACH OF THE ISSUER, THE TRUSTEE AND THE HOLDERS BY THEIR ACCEPTANCE OF ANY SECURITY HEREBY
IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL
BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE
TRANSACTION CONTEMPLATED HEREBY.

     Section 11.9 Counterparts. This Indenture may be executed in any number of
counterparts, each of which shall be an original; but such counterparts shall together constitute
but one and the same instrument.

     Section 11.10 Effect of Headings. The Article and Section headings herein and the
Table of Contents are for convenience only and shall not affect the construction hereof.

     Section 11.11 Securities in a Foreign Currency or in ECU. Unless otherwise specified
in an Officer’s Certificate delivered pursuant to Section 2.3 of this Indenture with respect to a
particular series of Securities, whenever for purposes of this Indenture any action may be taken by
the Holders of a specified percentage in aggregate principal amount of Securities of all series or
all series affected by a particular action at the time Outstanding and, at such time, there are
Outstanding Securities of any series which are denominated in a coin or currency other than Dollars
(including ECUs), then the principal amount of Securities of such series which shall be deemed to
be Outstanding for the purpose of taking such action shall be that amount of Dollars that could be
obtained for such amount at the Market Exchange Rate. For purposes of this Section 11.11, Market
Exchange Rate shall mean the noon Dollar buying rate in New York City for cable transfers of that
currency as published by the Federal Reserve Bank of New York; provided, however, in the case of
ECUs, Market Exchange Rate shall mean the rate of exchange determined by the Commission of the
European Communities (or any successor thereto) as published in the Official Journal of the
European Communities (such publication or any successor publication, the “Journal”). If such
Market Exchange Rate is not available for any reason with respect to such currency, the Trustee
shall use, in its sole discretion and without liability on its part, such quotation of the Federal
Reserve Bank of New York or, in the case of ECUs, the rate of exchange as published in the Journal,
as of the most recent available date, or quotations or, in the case of ECUs, rates of exchange from
one or more major banks in The City of New York or in the country of issue of the currency in
question, which for purposes of the ECU shall be Brussels, Belgium, or such other quotations or, in
the case of ECU, rates of exchange as the Trustee shall deem appropriate. The provisions of this
paragraph shall apply in determining the equivalent principal amount in respect of Securities of a
series denominated in a currency other than Dollars in connection with any action taken by Holders
of Securities pursuant to the terms of this Indenture.

     All decisions and determinations of the Trustee regarding the Market Exchange Rate or any
alternative determination provided for in the preceding paragraph shall be in its sole discretion
and shall, in the absence of manifest error, be conclusive to the extent permitted by law for all
purposes and irrevocably binding upon the Issuer and all Holders.

     Section 11.12 Judgment Currency. The Issuer agrees, to the fullest extent that it may
effectively do so under applicable law, that (1) if for the purpose of obtaining judgment in any
court it is necessary to convert the sum due in respect of the principal of or interest on the
Securities of any series (the “Required Currency”) into a currency in which a judgment will be
rendered (the “Judgment Currency”), the rate of exchange used shall be the rate at which in
accordance with normal banking procedures the Trustee could purchase in The City of New York the
Required Currency with the Judgment Currency on the day on which final unappealable judgment is
entered, unless such day is not a Business Day, then, to the extent permitted by applicable law,
the rate of exchange used shall be the rate at which in accordance with normal banking procedures
the Trustee could purchase in The City of New York the Required Currency with the Judgment Currency
on the Business Day preceding the day on which final unappealable judgment is entered and (2) its
obligations under this Indenture to make payments in the Required Currency (a) shall not be
discharged or satisfied by any tender, or any recovery pursuant to any judgment (whether or not
entered in accordance with subsection (1)), in any currency other than the Required Currency,
except to the extent that such tender or recovery shall result in the actual receipt, by the payee,
of the full amount of the Required Currency expressed to be payable in respect of such payments,
(b) shall be enforceable as an alternative or additional cause of action for the purpose of
recovering in the Required Currency the amount, if any, by which such actual receipt shall fall
short of the full amount of the Required Currency so expressed to be payable and (c) shall not be
affected by judgment being obtained for any other sum due under this Indenture.

     Section 11.13 Separability Clause. If any provision of this Indenture or of the
Securities, or the application of any such provision to any Person or circumstance, shall be held
to be invalid, illegal or unenforceable, the remainder of this Indenture or of the Securities, or
the application of such provision to Persons or circumstances other than those as to whom or which
it is invalid, illegal or unenforceable, shall not in any way be affected or impaired thereby.

ARTICLE 12

REDEMPTION OF SECURITIES AND SINKING FUNDS

     Section 12.1 Applicability of Article. The provisions of this Article shall be
applicable to the Securities of any series which are redeemable before their maturity or to any
sinking fund for the retirement of Securities of a series except as otherwise specified as
contemplated by Section 2.3 for Securities of such series.

     Section 12.2 Notice of Redemption; Partial Redemptions. Notice of redemption to the
Holders of Registered Securities of any series to be redeemed as a whole or in part at the option
of the Issuer shall be given by mailing notice of such redemption by first class mail, postage
prepaid, at least 30 days and not more than 60 days prior to the date fixed for redemption to such
Holders of Securities of such series at their last addresses as they shall appear upon the registry
books. Notice of redemption to the Holders of Unregistered Securities to be redeemed as a whole or
in part, who have filed their names and addresses with the Trustee pursuant to Section 313(c)(2) of
the Trust Indenture Act of 1939 shall be given at the Issuer’s expense by mailing notice of such
redemption, by first class mail, postage prepaid, at least 30 days and not more than 60 prior to
the date fixed for redemption, to such Holders at such addresses as were so furnished to the
Trustee (and, in the case of any such notice given by the Issuer, the Trustee shall make such
information available to the Issuer for such purpose). Notice of redemption to all other Holders
of Unregistered Securities shall be published in an Authorized Newspaper in the Borough of
Manhattan, The City of New York, and in an Authorized Newspaper in London (and, if required by
Section 3.10, in an Authorized Newspaper in Luxembourg), in each case, once in each of three
successive calendar weeks, the first publication to be not less than 30 nor more than 60 days prior
to the date fixed for redemption. Any notice which is mailed in the manner herein provided shall
be conclusively presumed to have been duly given, whether or not the Holder receives the notice.
Failure to give notice by mail, or any defect in the notice to the Holder of any Security of a
series designated for redemption as a whole or in part shall not affect the validity of the
proceedings for the redemption of any other Security of such series.

     The notice of redemption to each such Holder shall identify the securities to be redeemed
(including CUSIP numbers), shall specify, the principal amount of each Security of such series held
by such Holder to be redeemed, the date fixed for redemption, the redemption price, the place or
places of payment, that payment will be made upon presentation and surrender of such Securities
and, in the case of Securities with Coupons attached thereto, of all Coupons appertaining thereto
maturing after the date fixed for redemption, that such redemption is pursuant to the mandatory or
optional sinking fund, or both, if such be the case, that interest accrued to the date fixed for
redemption will be paid as specified in such notice and that on and after said date interest
thereon or on the portions thereof to be redeemed will cease to accrue. In case any Security of a
series is to be redeemed in part only the notice of redemption shall state the portion of the
principal amount thereof to be redeemed and shall state that on and after the date fixed for
redemption, upon surrender of such Security, a new Security or Securities of such series in
principal amount equal to the unredeemed portion thereof will be issued.

     The notice of redemption of Securities of any series to be redeemed at the option of the
Issuer shall be given by the Issuer or, at the Issuer’s request, by the Trustee in the name and at
the expense of the Issuer.

     On or before 10:00 a.m., New York City time, the redemption date specified in the notice of
redemption given as provided in this Section, the Issuer will deposit with the Trustee or with one
or more paying agents (or, if the Issuer is acting as its own paying agent, set aside, segregate
and hold in trust as provided in Section 3.3) an amount of money sufficient to redeem on the
redemption date all the Securities
of such series so called for redemption at the appropriate redemption price, together with
accrued interest to the date fixed for redemption. The Issuer will deliver to the Trustee at least
75 days prior to the date fixed for redemption (unless a shorter period shall be acceptable to the
Trustee) an Officer’s Certificate stating the aggregate principal amount of Securities to be
redeemed. In case of a redemption at the election of the Issuer prior to the expiration of any
restriction on such redemption, the Issuer shall deliver to the Trustee,

45

 

prior to the giving of any
notice of redemption to Holders pursuant to this Section, an Officer’s Certificate stating that
such restriction has been complied with.

     If less than all the Securities of a series are to be redeemed, the Trustee shall select, in
such manner as it shall deem appropriate and fair, which may include by lot, Securities of such
Series to be redeemed in whole or in part. Securities may be redeemed in part in multiples equal
to the minimum authorized denomination for Securities of such series or any multiple thereof. The
Trustee shall promptly notify the Issuer in writing of the Securities of such series selected for
redemption and, in the case of any Securities of such series selected for partial redemption, the
principal amount thereof to be redeemed. For all purposes of this Indenture, unless the context
otherwise requires, all provisions relating to the redemption of Securities of any series shall
relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the
principal amount of such Security which has been or is to be redeemed.

     Section 12.3 Payment of Securities Called for Redemption. If notice of redemption has
been given as above provided, the Securities or portions of Securities specified in such notice
shall become due and payable on the date and at the place stated in such notice at the applicable
redemption price, together with interest accrued to the date fixed for redemption, and on and after
said date (unless the Issuer shall default in the payment of such Securities at the redemption
price, together with interest accrued to said date) interest on the Securities or portions of
Securities so called for redemption shall cease to accrue, and the unmatured Coupons, if any,
appertaining thereto shall be void, and, except as provided in Sections 3.3 and 6.5, such
Securities shall cease from and after the date fixed for redemption to be entitled to any benefit
or security under this Indenture, and the Holders thereof shall have no right in respect of such
Securities except the right to receive the redemption price thereof and unpaid interest to the date
fixed for redemption. On presentation and surrender of such Securities at a place of payment
specified in said notice, together with all Coupons, if any, appertaining thereto maturing after
the date fixed for redemption, said Securities or the specified portions thereof shall be paid and
redeemed by the Issuer at the applicable redemption price, together with interest accrued thereon
to the date fixed for redemption; provided that payment of interest becoming due on or prior to the
date fixed for redemption shall be payable in the case of Securities with Coupons attached thereto,
to the Holders of the Coupons for such interest upon surrender thereof, and in the case of
Registered Securities, to the Holders of such Registered Securities registered as such on the
relevant record date subject to the terms and provisions of Sections 2.3 and 2.7 hereof.

     If any Security called for redemption shall not be so paid upon surrender thereof for
redemption, the principal shall, until paid or duly provided for, bear interest from the date fixed
for redemption at the rate of interest or Yield to Maturity (in the case of an Original Issue
Discount Security) borne by such Security.

     If any Security with Coupons attached thereto is surrendered for redemption and is not
accompanied by all appurtenant Coupons maturing after the date fixed for redemption, such Security
may be redeemed after deducting from the redemption price any amount equal to the face amount of
all such missing Coupons, or the surrender of such missing Coupon or Coupons may be waived by the
Issuer and the Trustee if there be furnished to them such security or indemnity as they may require
to save each of them and any paying agent harmless. If thereafter the Holder of such Security
shall surrender to the Trustee or any paying agent any such missing Coupon in respect of which a
deduction shall have been made from the redemption price, such Holder shall be entitled to receive
the amount so deducted; provided, however, that interest represented by Coupons shall be payable as
provided in Section 2.9 and, unless otherwise specified as contemplated by Section 2.3, only upon
presentation and surrender of those Coupons.

     Upon presentation of any Security redeemed in part only, the Issuer shall execute and the
Trustee shall authenticate and deliver to or on the order of the Holder thereof, at the expense of
the Issuer, a new
Security or Securities of such series, of authorized denominations, in principal amount equal
to the unredeemed portion of the Security so presented.

     Section 12.4 Exclusion of Certain Securities from Eligibility for Selection for
Redemption. Securities shall be excluded from eligibility for selection for redemption if they
are identified by

46

 

registration and certificate number in an Officer’s Certificate delivered to the
Trustee at least 40 days prior to the last date on which notice of redemption may be given as being
owned of record and beneficially by, and not pledged or hypothecated by either (a) the Issuer or
(b) an entity specifically identified in such written statement as directly or indirectly
controlling or controlled by or under direct or indirect common control with the Issuer.

     Section 12.5 Mandatory and Optional Sinking Funds. (a) The minimum amount of any
sinking fund payment provided for by the terms of the Securities of any series is herein referred
to as a “mandatory sinking fund payment”, and any payment in excess of such minimum amount provided
for by the terms of the Securities of any series is herein referred to as an “optional sinking fund
payment”. The date on which a sinking fund payment is to be made is herein referred to as the
“sinking fund payment date”.

     (b) In lieu of making all or any part of any mandatory sinking fund payment with respect to
any series of Securities in cash, the Issuer may at its option (i) deliver to the Trustee
Securities of such series theretofore purchased or otherwise acquired (except upon redemption
pursuant to the mandatory sinking fund) by the Issuer or receive credit for Securities of such
series (not previously so credited) theretofore purchased or otherwise acquired (except as
aforesaid) by the Issuer and delivered to the Trustee for cancellation pursuant to Section 2.10,
(ii) receive credit for optional sinking fund payments (not previously so credited) made pursuant to
this Section, or (iii) receive credit for Securities of such series (not previously so credited)
redeemed by the Issuer through any optional redemption provision contained in the terms of such
series. Securities so delivered or credited shall be received or credited by the Trustee at the
sinking fund redemption price specified in such Securities.

     (c) On or before the 60th day next preceding each sinking fund payment date for any series,
the Issuer will deliver to the Trustee an Officer’s Certificate (which need not contain the
statements required by Section 11.5) (i) specifying the portion of the mandatory sinking fund
payment to be satisfied by payment of cash and the portion to be satisfied by credit of Securities
of such series and the basis for such credit, (ii) stating that none of the Securities of such
series has theretofore been so credited, (iii) stating that no defaults in the payment of interest or
Events of Default with respect to such series have occurred (which have not been waived or cured)
and are continuing and (iv) stating whether or not the Issuer intends to exercise its right to make
an optional sinking fund payment with respect to such series and, if so, specifying the amount of
such optional sinking fund payment which the Issuer intends to pay on or before the next succeeding
sinking fund payment date. Any Securities of such series to be credited and required to be
delivered to the Trustee in order for the Issuer to be entitled to credit therefor as aforesaid
which have not theretofore been delivered to the Trustee shall be delivered for cancellation
pursuant to Section 2.10 to the Trustee with such Officer’s Certificate (or reasonably promptly
thereafter if acceptable to the Trustee). Such Officer’s Certificate shall be irrevocable and upon
its receipt by the Trustee the Issuer shall become unconditionally obligated to make all the cash
payments or payments therein referred to, if any, on or before the next succeeding sinking fund
payment date. Failure of the Issuer, on or before any such 60th day, to deliver such Officer’s
Certificate and Securities specified in this paragraph, if any, shall not constitute a default but
shall constitute, on and as of such date, the irrevocable election of
the Issuer (1) that the
mandatory sinking fund payment for such series due on the next succeeding sinking fund payment date
shall be paid entirely in cash without the option to deliver or credit Securities of such series in
respect thereof and (2) that the Issuer will make no optional sinking fund payment with respect to
such series as provided in this Section.

     (d) If the sinking fund payment or payments (mandatory or optional or both) to be made in cash
on the next succeeding sinking fund payment date plus any unused balance of any preceding sinking
fund payments made in cash shall exceed $50,000 (or the equivalent thereof in any Foreign Currency
or ECU) or a lesser sum in Dollars (or the equivalent thereof in any Foreign Currency or ECU) if
the Issuer
shall so request with respect to the Securities of any particular series, such cash shall be
applied on the next succeeding sinking fund payment date to the redemption of Securities of such
series at the sinking fund redemption price together with accrued interest to the date fixed for
redemption. If such amount shall be $50,000 (or the equivalent thereof in any
Foreign Currency or
ECU) or less and the Issuer makes no such request then it shall be carried over until a sum in
excess of $50,000 (or the equivalent thereof in any

47

 

Foreign Currency or ECU) is available. The
Trustee shall select, in the manner provided in Section 12.2, for redemption on such sinking fund
payment date a sufficient principal amount of Securities of such series to absorb said cash, as
nearly as may be, and shall (if requested in writing by the Issuer) inform the Issuer of the serial
numbers of the Securities of such series (or portions thereof) so selected. Securities shall be
excluded from eligibility for redemption under this Section if they are identified by registration
and certificate number in an Officer’s Certificate delivered to the Trustee at least 60 days prior
to the sinking fund payment date as being owned of record and beneficially by, and not pledged or
hypothecated by either (i) the Issuer or (ii) an entity specifically identified in such Officer’s
Certificate as directly or indirectly controlling or controlled by or under direct or indirect
common control with the Issuer. The Trustee, in the name and at the expense of the Issuer (or the
Issuer, if it shall so request the Trustee in writing) shall cause notice of redemption of the
Securities of such series to be given in substantially the manner provided in Section 12.2 (and
with the effect provided in Section 12.3) for the redemption of Securities of such series in part
at the option of the Issuer. The amount of any sinking fund payments not so applied or allocated
to the redemption of Securities of such series shall be added to the next cash sinking fund payment
for such series and, together with such payment, shall be applied in accordance with the provisions
of this Section. Any and all sinking fund monies held on the stated maturity date of the
Securities of any particular series (or earlier, if such maturity is accelerated), which are not
held for the payment or redemption of particular Securities of such series shall be applied,
together with other monies, if necessary, sufficient for the purpose, to the payment of the
principal of, and interest on, the Securities of such series at maturity.

     (e) On or before each sinking fund payment date, the Issuer shall pay to the Trustee in cash
or shall otherwise provide for the payment of all interest accrued to the date fixed for redemption
on Securities to be redeemed on the next following sinking fund payment date.

     (f) The Trustee shall not redeem or cause to be redeemed any Securities of a series with
sinking fund monies or give any notice of redemption of Securities for such series by operation of
the sinking fund during the continuance of a default in payment of interest on such Securities or
of any Event of Default except that, where the giving of notice of redemption of any Securities
shall theretofore have been made, the Trustee shall redeem or cause to be redeemed such Securities,
provided that it shall have received from the Issuer a sum sufficient for such redemption. Except
as aforesaid, any monies in the sinking fund for such series at the time when any such default or
Event of Default shall occur, and any monies thereafter paid into the sinking fund, shall, during
the continuance of such default or Event of Default, be deemed to have been collected under Article
5 and held for the payment of all such Securities. In case such Event of Default shall have been
waived as provided in Section 5.10 or the default cured on or before the sixtieth day preceding the
sinking fund payment date in any year, such monies shall thereafter be applied on the next
succeeding sinking fund payment date in accordance with this Section to the redemption of such
Securities.

substantially identical, except in the case of Registered Securities as to denomination and except
as may otherwise be provided by or pursuant to the Board Resolution or Officer’s Certificate
referred to above or as set forth in any such indenture supplemental hereto. All Securities of any

Officer’s Certificate be issued from time to time, consistent with the terms of this Indenture, if
so provided by or pursuant to such Board Resolution, such Officer’s Certificate or in any such
indenture supplemental hereto.

     Section 2.4 Authentication and Delivery of Securities. (a) The Issuer may deliver
Securities of any series having attached thereto appropriate Coupons, if any, executed by the
Issuer to the Trustee for authentication together with the applicable documents referred to below
in this Section, and the

8

 

Trustee shall thereupon authenticate and deliver such Securities to or upon the order of the
Issuer (contained in the Issuer Order referred to below in this Section) or pursuant to such
procedures acceptable to the Trustee and to such recipients as may be specified from time to time
by an Issuer Order. The maturity date, original issue date, interest rate and any other terms of
the Securities of such series and Coupons, if any, appertaining thereto shall be determined by or
pursuant to such Issuer Order and procedures. In authenticating such Securities and accepting the
additional responsibilities under this Indenture in relation to such Securities, the Trustee shall
be entitled to receive and (subject to Section 6.1) shall be fully protected in relying upon,
unless and until such documents have been superseded or revoked:

     (i) an Issuer Order requesting such authentication and setting forth delivery
instructions if the Securities and Coupons, if any, are not to be delivered to the Issuer,
provided that, with respect to Securities of a series subject to a
Periodic Offering, (1)
such Issuer Order may be delivered by the Issuer to the Trustee prior to the delivery to
the Trustee of such Securities for authentication and delivery, (2) the Trustee shall
authenticate and deliver Securities of such series for original issue from time to time, in
an aggregate principal amount not exceeding the aggregate principal amount established for
such series, pursuant to an Issuer Order or pursuant to procedures acceptable to the
Trustee as may be specified from time to time by an Issuer Order, and
(3) the maturity
date or dates, original issue date or dates, interest rate or rates and any other terms of
Securities of such series shall be determined by an Issuer Order or pursuant to such
procedures;

     (ii) any Board Resolution, Officer’s Certificate and/or executed supplemental
indenture referred to in Sections 2.1 and 2.3 by or pursuant to which the forms and terms
of the Securities and Coupons, if any, were established;

     (iii) an Officer’s Certificate setting forth the form or forms and terms of the
Securities and Coupons, if any, stating that the form or forms and terms of the Securities
and Coupons, if any, have been established pursuant to Sections 2.1 and 2.3 and comply with
this Indenture, and covering such other matters as the Trustee may reasonably request; and

     (iv) at the option of the Issuer, either one or more Opinions of Counsel, or a letter
addressed to the Trustee permitting it to conclusively rely, as to the truth of the
statements and the correctness of the opinions expressed therein, on one or more Opinions
of Counsel, substantially to the effect that:

                    (1) the forms of the Securities and Coupons, if any, have been duly
authorized and established in conformity with the provisions of this Indenture;

                    (2) in the case of an underwritten offering, the terms of the Securities have
been duly authorized and established in conformity with the provisions of this
Indenture, and, in the case of an offering that is not underwritten, certain terms
of the Securities have been established pursuant to a Board Resolution, an
Officer’s Certificate or a supplemental indenture in accordance with this
Indenture, and when such other terms as are to be established pursuant to
procedures set forth in an Issuer Order shall have been established, all such
terms will have been duly authorized by the Issuer and will have been established
in conformity with the provisions of this Indenture;

                    (3) when the Securities and Coupons, if any, have been executed by the Issuer
and authenticated by the Trustee in accordance with the provisions of this
Indenture and delivered to and duly paid for by the purchasers thereof, they will
have been duly issued under this Indenture, will be entitled to the benefits of
this Indenture, and will be valid and binding obligations of the Issuer,
enforceable in accordance with their respective terms; and

9

 

                    (4) that all applicable laws and requirements in respect of the execution and
delivery by the Issuer of such Securities have been complied with.

     In rendering such opinions, any counsel may qualify any opinions by stating that the validity
or enforceability of any agreements or instruments may be limited by bankruptcy, insolvency,
reorganization, liquidation, moratorium and other similar laws affecting the rights and remedies of
creditors and by general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law). Such counsel may rely upon opinions of other
counsel (copies of which shall be delivered to the Trustee), who shall be counsel reasonably
satisfactory to the Trustee, in which case the opinion shall state that such counsel believes he or
she and the Trustee are entitled so to rely. Such counsel may also state that, insofar as such
opinion involves factual matters, he or she has relied, to the extent he or she deems proper, upon
certificates of officers of the Issuer and its subsidiaries and certificates of public officials.

     (b) The Trustee shall have the right to decline to authenticate and deliver any Securities
under this Section if the Trustee, being advised by counsel, determines that such action may not
lawfully be taken by the Issuer or if the Trustee in good faith by its board of directors or board
of trustees, executive committee, or a trust committee of directors or trustees or Responsible
Officers shall determine that such action would expose the Trustee to personal liability to
existing Holders or would affect the Trustee’s own rights, duties or immunities under the
Securities, this Indenture or otherwise.

     (c) If the Issuer shall establish pursuant to Section 2.3 that the Securities of a series are
to be issued in whole or in part in global form, then the Issuer shall execute and the Trustee
shall, in accordance with this Section and the Issuer Order with respect to such series,
authenticate and deliver one or more Securities in global form that (i) shall represent and shall
be denominated in an amount equal to the aggregate principal amount of all of the Securities of
such series issued and not yet cancelled, (ii) if such Securities are Registered Securities, shall
be registered in the name of the Depositary for such Security or Securities in global form or the
nominee of such Depositary, (iii) if such Securities are Registered Securities, shall be delivered by
the Trustee to such Depositary or pursuant to such Depositary’s
instructions and (iv) shall bear a
legend substantially to the following effect:

“Unless and until it is exchanged in whole or in part for Securities in definitive
form, this Security may not be transferred except as a whole by the Depositary to
the nominee of the Depositary or by a nominee of the Depositary to the Depositary
or another nominee of the Depositary or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary.”

     The Trustee shall have no responsibility for any action taken or not taken by the Depositary.

     (d) Each Depositary designated pursuant to Section 2.3 must, at the time of its designation
and at all times while it serves as Depositary, be a clearing agency registered under the
Securities Exchange Act of 1934 and any other applicable statute or regulation.

     Section 2.5 Execution of Securities. The Securities and, if applicable, each Coupon
appertaining thereto shall be signed on behalf of the Issuer by the chairman or vice chairman of
its Board of Directors or its president or any executive, senior or other vice president or its
treasurer, but need not, be attested. Such signatures may be the manual or facsimile signatures of
the present or any future such officers. Typographical and other minor errors or defects in any
such signature shall not affect the validity or enforceability of any Security that has been duly
authenticated and delivered by the Trustee.

     In case any officer of the Issuer who shall have signed any of the Securities or Coupons, if
any, shall cease to be such officer before the Security or Coupon so signed (or the Security to
which the Coupon so signed appertains) shall be authenticated and delivered by the Trustee or
disposed of by the Issuer, such Security or Coupon nevertheless may be authenticated and delivered
or disposed of as though the person who signed such Security or Coupon had not ceased to be such
officer of the Issuer; and any

10

 

Security or Coupon may be signed on behalf of the Issuer by such persons as, at the actual
date of the execution of such Security or Coupon, shall be the proper officers of the Issuer,
although at the date of the execution and delivery of this Indenture any such person was not such
an officer.

     Section 2.6 Certificate of Authentication. Only such Securities as shall bear thereon
a certificate of authentication substantially in the form herein before recited, executed by the
Trustee by the manual signature of one of its authorized signatories, shall be entitled to the
benefits of this Indenture or be valid or obligatory for any purpose. No Coupon shall be entitled
to the benefits of this Indenture or shall be valid and obligatory for any purpose until the
certificate of authentication on the Security to which such Coupon appertains shall have been duly
executed by the Trustee. The execution of such certificate by the Trustee upon any Security
executed by the Issuer shall be conclusive evidence that the Security so authenticated has been
duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this
Indenture.

     Section 2.7 Denomination and Date of Securities; Payments of Interest. The Securities
of each series shall be issuable as Registered Securities or Unregistered Securities in
denominations established as contemplated by Section 2.3 or, with respect to the Registered
Securities of any series, if not so established, in denominations of $1,000 and any integral
multiple thereof. If denominations of Unregistered Securities of any series are not so
established, such Securities shall be issuable in denominations of $1,000 and $5,000. The
Securities of each series shall be numbered, lettered or otherwise distinguished in such manner or
in accordance with such plan as the officers of the Issuer executing the same may determine, as
evidenced by the execution and authentication thereof.

     Each Registered Security shall be dated the date of its authentication. Each Unregistered
Security shall be dated as provided in the resolution or resolutions of the Board of Directors of
the Issuer referred to in Section 2.3. The Securities of each series shall bear interest, if any,
from the date, and such interest shall be payable on the dates, established as contemplated by
Section 2.3.

     The person in whose name any Registered Security of any series is registered at the close of
business on any record date applicable to a particular series with respect to any interest payment
date for such series shall be entitled to receive the interest, if any, payable on such interest
payment date notwithstanding any transfer or exchange of such Registered Security subsequent to the
record date and prior to such interest payment date, except if and to the extent the Issuer shall
default in the payment of the interest due on such interest payment date for such series, in which
case such defaulted interest shall be paid to the persons in whose names Outstanding Registered
Securities for such series are registered at the close of business on a subsequent record date
(which shall be not less than five Business Days prior to the date of payment of such defaulted
interest) established by notice given by mail by or on behalf of the Issuer to the Holders of
Registered Securities not less than 15 days preceding such subsequent record date. The term
“record date” as used with respect to any interest payment date (except a date for payment of
defaulted interest) for the Securities of any series shall mean the date specified as such in the
terms of the Registered Securities of such series established as contemplated by Section 2.3, or,
if no such date is so established, if such interest payment date is the first day of a calendar
month, the fifteenth day of the next preceding calendar month or, if such interest payment date is
the fifteenth day of a calendar month, the first day of such calendar month, whether or not such
record date is a Business Day.

     Section 2.8 Registration, Transfer and Exchange. (a) The Issuer will keep at each
office or agency to be maintained for the purpose as provided in Section 3.2 for each series of
Securities a register or registers in which, subject to such reasonable regulations as it may
prescribe, it will provide for the registration of Registered Securities of such series and the
registration of transfer of Registered Securities of such series. Such register shall be in
written form in the English language. At all reasonable times such register or registers shall be
open for inspection by the Trustee.

     (b) Upon due presentation for registration of transfer of any Registered Security of any
series at any such office or agency to be maintained for the purpose as provided in Section 3.2,
the Issuer shall execute and the Trustee shall authenticate and deliver in the name of the
transferee or transferees a new

11

 

Registered Security or Registered Securities of the same series, maturity date, interest rate
and original issue date in authorized denominations for a like aggregate principal amount.

     Unregistered Securities (except for any temporary Unregistered Securities in global form) and
Coupons (except for Coupons attached to any temporary Unregistered Securities in global form) shall
be transferable by delivery.

     (c) (i) At the option of the Holder thereof, Registered Securities of any series (other than
a Registered Security in global form, except as set forth below) may be exchanged for a Registered
Security or Registered Securities of such series having authorized denominations and an equal
aggregate principal amount, upon surrender of such Registered Securities to be exchanged at the
agency of the Issuer that shall be maintained for such purpose in accordance with Section 3.2 and
upon payment, if the Issuer shall so require, of the charges hereinafter provided. Whenever any
Registered Securities are so surrendered for exchange, the Issuer shall execute, and the Trustee
shall authenticate and deliver, the Registered Securities which the Holder making the exchange is
entitled to receive.

     (ii) Unless otherwise specified as contemplated by Section 2.3, at the option of the
Holder, Unregistered Securities of such series may be exchanged for Registered Securities
(if the Securities of such series are issuable in registered form) or Unregistered
Securities (if Unregistered Securities of such series are issuable in more than one
denomination and such exchanges are permitted by such series) of the same series, of any
authorized denominations and of like tenor and aggregate principal amount, upon surrender
of the Securities to be exchanged at the agency of the Issuer that shall be maintained for
such purpose in accordance with Section 3.2, with all unmatured Coupons and all matured
Coupons in default thereto appertaining. If the Holder of an Unregistered Security is
unable to produce any such unmatured Coupon or Coupons or matured Coupon or Coupons in
default, such exchange may be effected if the Unregistered Securities are accompanied by
payment in funds acceptable to the Issuer and the Trustee in an amount equal to the face
amount of such missing Coupon or Coupons, or the surrender of such missing Coupon or
Coupons may be waived by the Issuer and the Trustee if there be furnished to them such
security or indemnity as they may require to save each of them and any paying agent
harmless. If thereafter the Holder of such Security shall surrender to any paying agent
any such missing Coupon in respect of which such a payment shall have been made, such
Holder shall be entitled to receive the amount of such payment as provided in Section 3.2.
Notwithstanding the foregoing, in case any Unregistered Security of any series is
surrendered at any such office or agency in exchange for a Registered Security of the same
series after the close of business at such office or agency on (1) any record date and
before the opening of business at such office or agency on the relevant interest payment
date, or (2) any special record date for payment of defaulted interest and before the
opening of business at such office or agency on the related date for payment of defaulted
interest, such Unregistered Security shall be surrendered without the Coupon relating to
such interest or defaulted interest payment date or proposed date of payment, as the case
may be (or, if such Coupon is so surrendered with such Unregistered Security, such Coupon
shall be returned to the person so surrendering the Unregistered Security), and interest or
defaulted interest, as the case may be, will not be payable on such date or proposed date
for payment, as the case may be, in respect of the Registered Security issued in exchange
for such Unregistered Security, but will be payable only to the Holder of such Coupon, when
due in accordance with the provisions of this Indenture.

     (iii) Registered Securities of any series may not be exchanged for Unregistered
Securities of such series unless (1) otherwise specified
pursuant to Section 2.3 and (2)
the Issuer has delivered to the Trustee an Opinion of Counsel that (A) the Issuer has
received from the Internal Revenue Service a ruling or (B) since the date hereof, there has
been a change in the applicable Federal income tax law, in either case to the effect that
the inclusion of terms permitting Registered Securities to be exchanged for Unregistered
Securities would result in no adverse Federal income tax effect to the Issuer or to any
Holder. Whenever any Securities are so surrendered for exchange, the Issuer shall execute,
and the Trustee shall authenticate and deliver, the Securities which the Holder making the
exchange is entitled to receive. All Securities and

12

 

Coupons surrendered upon any exchange or transfer provided for in this Indenture shall
be cancelled promptly and disposed of by the Trustee in accordance with its procedures for
the disposition of cancelled securities in effect as of the date of such cancellation and
the Trustee will deliver a certificate of disposition thereof to the Issuer.

     (d) All Registered Securities presented for registration of transfer, exchange, redemption or
payment shall (if so required by the Issuer or the Trustee) be duly endorsed by, or be accompanied
by a written instrument or instruments of transfer in form satisfactory to the Issuer and the
Trustee duly executed by the Holder or his or her attorney duly authorized in writing.

     The Issuer may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any exchange or registration of transfer of
Securities. No service charge shall be made for any such transaction.

     The Issuer shall not be required to exchange or register a transfer of (a) any Securities of
any series for a period of 15 days next preceding the first mailing of notice of redemption of
Securities of such series to be redeemed or (b) any Securities selected, called or being called for
redemption, in whole or in part, except, in the case of any Security to be redeemed in part, the
portion thereof not so to be redeemed.

     (e) Notwithstanding any other provision of this Section 2.8, unless and until it is exchanged
in whole or in part for Securities in definitive registered form, a Registered Security in global
form representing all or a portion of the Securities of a series may not be transferred except as a
whole by the Depositary for such series to a nominee of such Depositary or by a nominee of such
Depositary to such Depositary or another nominee of such Depositary or by such Depositary or any
such nominee to a successor Depositary for such series or a nominee of such successor Depositary.

     If at any time the Depositary for any Registered Securities of a series represented by one or
more Registered Securities in global form notifies the Issuer that it is unwilling or unable to
continue as Depositary for such Registered Securities or if at any time the Depositary for such
Registered Securities shall no longer be eligible under Section 2.4, the Issuer shall appoint a
successor Depositary eligible under Section 2.4 with respect to such Registered Securities. If a
successor Depositary eligible under Section 2.4 for such Registered Securities is not appointed by
the Issuer within 90 days after the Issuer receives such notice or becomes aware of such
ineligibility, the Issuer’s election pursuant to Section 2.3 that such Registered Securities be
represented by one or more Registered Securities in global form shall no longer be effective and
the Issuer will execute, and the Trustee, upon receipt of an Officer’s Certificate for the
authentication and delivery of definitive Securities of such series, will authenticate and deliver,
Securities of such series in definitive registered form without Coupons, in any authorized
denominations, in an aggregate principal amount equal to the principal amount of the Registered
Security or Securities in global form representing such Registered Securities in exchange for such
Registered Security or Securities in global form.

     The Issuer may at any time and in its sole discretion determine that the Registered Securities
of any series issued in the form of one or more Registered Securities in global form shall no
longer be represented by a Registered Security or Securities in global form. In such event the
Issuer will execute, and the Trustee, upon receipt of an Issuer Order for the authentication and
delivery of definitive Securities of such series, will authenticate and deliver, Securities of such
series in definitive registered form without Coupons, in any authorized denominations, in an
aggregate principal amount equal to the principal amount of the Registered Security or Securities
in global form representing such Registered Securities, in exchange for such Registered Security or
Securities in global form.

     If specified by the Issuer pursuant to Section 2.3 with respect to Securities represented by a
Registered Security in global form, the Depositary for such Registered Security in global form may
surrender such Registered Security in global form in exchange in whole or in part for Registered
Securities of the same series in definitive form on such terms as are acceptable to the Issuer and
such Depositary. Thereupon, the Issuer shall execute, and the Trustee shall authenticate and
deliver, without service charge,

13

 

     (i) to the Person specified by such Depositary a new Registered Security or Securities
of the same series, of any authorized denominations as requested by such Person, in an
aggregate principal amount equal to and in exchange for such Person’s beneficial interest
in the Registered Security in global form; and

     (ii) to such Depositary a new Registered Security in global form in a denomination
equal to the difference, if any, between the principal amount of the surrendered Registered
Security in global form and the aggregate principal amount of Registered Securities
authenticated and delivered pursuant to clause (i) above.

     Upon the exchange of a Registered Security in global form for Registered Securities in
definitive form without Coupons, in authorized denominations, such Registered Security in global
form shall be cancelled by the Trustee or an agent of the Issuer or the Trustee. Registered
Securities in definitive form issued in exchange for a Registered Security in global form pursuant
to this Section 2.8 shall be registered in such names and in such authorized denominations as the
Depositary for such Registered Security in global form, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee or an agent of the Issuer or the
Trustee. The Trustee or such agent shall deliver such Securities to or as directed by the Persons
in whose names such Securities are so registered.

     (f) All Securities issued upon any transfer or exchange of Securities shall be valid
obligations of the Issuer, evidencing the same debt, and entitled to the same benefits under this
Indenture, as the Securities surrendered upon such transfer or exchange.

     (g) Notwithstanding anything herein or in the terms of any series of Securities to the
contrary, none of the Issuer, the Trustee or any agent of the Issuer or the Trustee (any of which,
other than the Issuer, shall conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, on an Officer’s Certificate and an Opinion of
Counsel) shall be required to exchange any Unregistered Security for a Registered Security if such
exchange would result in adverse income tax consequences to the Issuer.

     (h) The Trustee shall have no obligation or duty to monitor, determine or inquire as to
compliance with any restrictions on transfer imposed under this Indenture or under applicable law
with respect to any transfer of any interest in any Security (including any transfers between or
among Depositary Participants or beneficial owners of interests in any Global Security) other than
to require delivery of such certificates and other documentation or evidence as are expressly
required by, and to do so if and when expressly required by the terms of, this Indenture, and to
examine the same to determine substantial compliance as to form with the express requirements
hereof.

     Section 2.9 Mutilated, Defaced, Destroyed, Lost and Stolen Securities. In case any
Security or any Coupon appertaining to any Security shall become mutilated, defaced or be
destroyed, lost or stolen, the Issuer in its discretion may execute, and upon the written request
of any officer of the Issuer, the Trustee shall authenticate and deliver a new Security of the same
series, maturity date, interest rate and original issue date, bearing a number or other
distinguishing symbol not contemporaneously outstanding, in exchange and substitution for the
mutilated or defaced Security, or in lieu of and in substitution for the Security so destroyed,
lost or stolen with Coupons corresponding to the Coupons appertaining to the Securities so
mutilated, defaced, destroyed, lost or stolen, or in exchange or substitution for the Security to
which such mutilated, defaced, destroyed, lost or stolen Coupon appertained, with Coupons
appertaining thereto corresponding to the Coupons so mutilated, defaced, destroyed, lost or stolen.
In every case the applicant for a substitute Security or Coupon shall furnish to the Issuer and to
the Trustee and any agent of the Issuer or the Trustee such security or indemnity as may be
required by them to indemnify and defend and to save each of them harmless and, in every case of
destruction, loss or theft, evidence to their satisfaction of the destruction, loss or theft of
such Security or Coupon and of the ownership thereof and in the case of mutilation or defacement
shall surrender the Security and related Coupons to the Trustee or such agent.

14

 

     Upon the issuance of any substitute Security or Coupon, the Issuer 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) or its agent
connected therewith. In case any Security or Coupon which has matured or is about to mature or has
been called for redemption in full shall become mutilated or defaced or be destroyed, lost or
stolen, the Issuer may instead of issuing a substitute Security, pay or authorize the payment of
the same or the relevant Coupon (without surrender thereof except in the case of a mutilated or
defaced Security or Coupon), if the applicant for such payment shall furnish to the Issuer and to
the Trustee and any agent of the Issuer or the Trustee such security or indemnity as any of them
may require to save each of them harmless, and, in every case of destruction, loss or theft, the
applicant shall also furnish to the Issuer and the Trustee and any agent of the Issuer or the
Trustee evidence to their satisfaction of the destruction, loss or theft of such Security or Coupon
and of the ownership thereof.

     Every substitute Security or Coupon of any series issued pursuant to the provisions of this
Section by virtue of the fact that any such Security or Coupon is destroyed, lost or stolen shall
constitute an additional contractual obligation of the Issuer, whether or not the destroyed, lost
or stolen Security or Coupon shall be at any time enforceable by anyone and shall be entitled to
all the benefits of (but shall be subject to all the limitations of rights set forth in) this
Indenture equally and proportionately with any and all other Securities or Coupons of such series
duly authenticated and delivered hereunder. All Securities and Coupons shall be held and owned
upon the express condition that, to the extent permitted by law, the foregoing provisions are
exclusive with respect to the replacement or payment of mutilated, defaced or destroyed, lost or
stolen Securities and Coupons and shall preclude any and all other rights or remedies
notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to
the replacement or payment of negotiable instruments or other securities without their surrender.

     Section 2.10 Cancellation of Securities; Destruction Thereof. All Securities and
Coupons surrendered for payment, redemption, registration of transfer or exchange, or for credit
against any payment in respect of a sinking or analogous fund, if surrendered to the Issuer or any
agent of the Issuer or the Trustee or any agent of the Trustee, shall be delivered to the Trustee
or its agent for cancellation or, if surrendered to the Trustee, shall be cancelled by it; and no
Securities or Coupons shall be issued in lieu thereof except as expressly permitted by any of the
provisions of this Indenture. The Trustee or its agent shall dispose of cancelled Securities and
Coupons held by it in accordance with its procedures for the disposition of cancelled securities
in effect as of the date of such cancellation. If the Issuer or its agent shall acquire any of the
Securities or Coupons, such acquisition shall not operate as a redemption or satisfaction of the
indebtedness represented by such Securities or Coupons unless and until the same are delivered to
the Trustee or its agent for cancellation.

     Section 2.11 Temporary Securities. Pending the preparation of definitive Securities
for any series, the Issuer may execute and the Trustee shall authenticate and deliver temporary
Securities for such series (printed, lithographed, typewritten or otherwise reproduced, in each
case in form satisfactory to the Trustee). Temporary Securities of any series shall be issuable as
Registered Securities without Coupons, or as Unregistered Securities with or without Coupons
attached thereto, of any authorized denomination, and substantially in the form of the definitive
Securities of such series but with such omissions, insertions and variations as may be appropriate
for temporary Securities, all as may be determined by the Issuer with the concurrence of the
Trustee as evidenced by the execution and authentication thereof. Temporary Securities may
contain such references to any provisions of this Indenture as may be appropriate. Every temporary
Security shall be executed by the Issuer and be authenticated by the Trustee upon the same
conditions and in substantially the same manner, and with like effect, as the definitive
Securities. Without unreasonable delay the Issuer shall execute and shall furnish definitive
Securities of such series and thereupon temporary Registered Securities of such series may be
surrendered in exchange therefor without charge at each office or agency to be maintained by the
Issuer for that purpose pursuant to Section 3.2 and, in the case of Unregistered Securities, at any
agency maintained by the Issuer for such purpose as specified pursuant to Section 3.2, and the
Trustee shall authenticate and deliver in exchange for such temporary Securities of such series an
equal aggregate principal amount of definitive Securities of the same series having authorized
denominations and, in the case of Unregistered Securities, having attached thereto any appropriate
Coupons. Until so exchanged, the temporary Securities of any series shall be entitled to the

15

 

same benefits under this Indenture as definitive Securities of such series, unless otherwise
established pursuant to Section 2.3. The provisions of this Section are subject to any
restrictions or limitations on the issue and delivery of temporary Unregistered Securities of any
series that may be established pursuant to Section 2.3 (including any provision that Unregistered
Securities of such series initially be issued in the form of a single Unregistered Security in
global form to be delivered to a Depositary or agency located outside the United States and the
procedures pursuant to which Unregistered Securities in definitive or global form of such series
would be issued in exchange for such temporary Unregistered Security in global form).

     Section 2.12 Global Securities. Neither the Trustee nor any Agent shall have any
responsibility for any actions taken or not taken by the Depositary.

     None of the Issuer, the Trustee, any paying agent, any Security registrar or any other agent
of the Issuer or any agent of the Trustee shall have any responsibility or liability for any aspect
of the records relating to or payments made on account of beneficial ownership interests of a
Security in global form or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests. The Issuer, the Trustee, any paying agent, any Security registrar
and any other agent of the Issuer and any agent of the Trustee shall be entitled to deal with the
Depositary, and any nominee thereof, that is the Holder of any such global Security for all
purposes of this Indenture relating to such global Security (including the payment of principal,
premium, if any, and interest and additional amounts, if any, and the giving of instructions or
directions by or to the owner or holder of a beneficial ownership interest in such global Security)
as the sole Holder of such global Security and shall have no obligations to the beneficial owners
thereof. None of the Issuer, the Trustee, any paying agent, any Security registrar or any other
agent of the Issuer or any agent of the Trustee shall have any responsibility or liability for any
acts or omissions of any such Depositary with respect to such global Security, for the records of
any such Depositary, including records in respect of beneficial ownership interests in respect of
any such global Security, for any transactions between such Depositary and any participant in such
Depositary or between or among any such Depositary, any such participant and/or any holder or owner
of a beneficial interest in such global Security or for any transfers of beneficial interests in
any such global Security. Notwithstanding the foregoing, with respect to any Security in global
form, nothing herein shall prevent the Issuer, the Trustee, or any agent of the Issuer or the
Trustee, from giving effect to any written certification, proxy or other authorization furnished by
the Depositary, as a Holder with respect to such global Security, or impair, as between such
Depositary and owners of beneficial interests in such global Security, the operation of customary
practices governing the exercise of the rights of such Depositary as a Holder of such global
Security.

     Section 2.13 CUSIP Numbers. The Issuer in issuing the Securities may use “CUSIP”,
“ISIN” or other similar numbers (if then generally in use), and, if so used by the Issuer, the
Trustee shall use “CUSIP”, “ISIN” or other similar 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. The Issuer will promptly notify the Trustee of any change in the
“CUSIP”, “ISIN” or other similar numbers.

ARTICLE 3

COVENANTS OF THE ISSUER

     Section 3.1 Payment of Principal, Premium and Interest. The Issuer covenants and
agrees for the benefit of each series of Securities that it will duly and punctually pay or cause
to be paid the principal of, and premium, if any, and interest on, each of the Securities of such
series (together with any additional amounts payable pursuant to the terms of such Securities) at
the place or places, at the respective times and in the manner provided in such Securities and in
the Coupons, if any, appertaining thereto and in this Indenture. The interest on Securities with
Coupons attached (together with any additional amounts payable pursuant to the terms of such
Securities) shall be payable only upon presentation and surrender of

16

 

the several Coupons for such interest installments as are evidenced thereby as they severally
mature. If any temporary Unregistered Security provides that interest thereon may be paid while
such Security is in temporary form, the interest on any such temporary Unregistered Security
(together with any additional amounts payable pursuant to the terms of such Security) shall be
paid, as to the installments of interest evidenced by Coupons attached thereto, if any, only upon
presentation and surrender thereof, and, as to the other installments of interest, if any, only
upon presentation of such Securities for notation thereon of the payment of such interest, in each
case subject to any restrictions that may be established pursuant to Section 2.3. The interest on
Registered Securities (together with any additional amounts payable pursuant to the terms of such
Securities) shall be payable only to or upon the written order of the Holders thereof and, at the
option of the Issuer, may be paid by wire transfer or by mailing checks for such interest payable
to or upon the written order of such Holders at their last addresses as they appear on the registry
books of the Issuer.

     Section 3.2 Offices for Payments, Etc. So long as any Securities are issued as
Registered Securities, the Issuer will maintain in the Borough of Manhattan, The City of New York,
an office or agency where the Registered Securities of each series may be presented for payment,
where the Securities of each series may be presented for exchange as is provided in this Indenture
and, if applicable, pursuant to Section 2.3 and where the Registered Securities of each series may
be presented for registration of transfer as in this Indenture provided.

     So long as any Securities are issued as Unregistered Securities, the Issuer will maintain one
or more offices or agencies in a city or cities located outside the United States (including any
city in which such an agency is required to be maintained under the rules of any stock exchange on
which the Securities of such series are listed) where the Unregistered Securities, if any, of each
series and Coupons, if any, appertaining thereto may be presented for payment. No payment on any
Unregistered Security or Coupon will be made upon presentation of such Unregistered Security or
Coupon at an agency of the Issuer within the United States nor will any payment be made by transfer
to an account in, or by mail to an address in, the United States unless pursuant to applicable
United States laws and regulations then in effect such payment can be made without adverse tax
consequences to the Issuer. Notwithstanding the foregoing, payments in Dollars of Unregistered
Securities of any series and Coupons appertaining thereto which are payable in Dollars may be made
at an agency of the Issuer maintained in the Borough of Manhattan, The City of New York, if such
payment in Dollars at each agency maintained by the Issuer outside the United States for payment on
such Unregistered Securities is illegal or effectively precluded by exchange controls or other
similar restrictions.

     The Issuer will maintain in the Borough of Manhattan, The City of New York, an office or
agency where notices and demands to or upon the Issuer in respect of the Securities of any series,
the Coupons appertaining thereto or this Indenture may be served.

     The Issuer will give to the Trustee written notice of the location of each such office or
agency and of any change of location thereof. In case the Issuer shall fail to maintain any agency
required by this Section, or shall fail to give such notice of the location or of any change in the
location of any of the above agencies, presentations and demands may be made and notices may be
served at the Corporate Trust Office of the Trustee.

     The Issuer may from time to time designate one or more additional offices or agencies where
the Securities of a series and any Coupons appertaining thereto may be presented for payment, where
the Securities of that series may be presented for exchange as provided in this Indenture and
pursuant to Section 2.3 and where the Registered Securities of that series may be presented for
registration of transfer as in this Indenture provided, and the Issuer may from time to time
rescind any such designation, as the Issuer may deem desirable or expedient; provided, however,
that no such designation or rescission shall in any manner relieve the Issuer of its obligation to
maintain the agencies provided for in this Section. The Issuer will give to the Trustee prompt
written notice of any such designation or rescission thereof.

     Section 3.3 Money for Security Payments to be Held in Trust; Unclaimed Money. If the
Issuer shall at any time act as its own paying agent, it will, on or before each due date of the
principal of

17

 

and premium, if any, or interest on any of the Securities, segregate and hold in trust for the
benefit of the Holders entitled thereto a sum sufficient to pay the principal (and premium, if any)
or interest so becoming due until such sums shall be paid to such Holders or otherwise disposed of
as herein provided and will promptly notify the Trustee of its action or failure so to act.

     Whenever the Issuer shall have one or more paying agents, it will, on or prior to each due
date of the principal of and premium, if any, or interest on any Securities, deposit with the
paying agent or paying agents a sum sufficient to pay the principal, premium, if any, or interest
so becoming due, such sum to be held in trust for the benefit of the Holders entitled to such
principal, premium, if any, or interest, and, unless such paying agent is the Trustee, the Issuer
will promptly notify the Trustee of its action or failure so to act.

     The Issuer will cause each paying agent 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:

     (a) hold all sums held by it for the payment of the principal of and premium, if any, or
interest on Securities in trust for the benefit of the Holders entitled thereto until such sums
shall be paid to such Persons or otherwise disposed of as herein provided;

     (b) give the Trustee notice of any default by the Issuer (or any other obligor upon the
Securities) in the making of any payment of principal and premium, if any, or interest; and

     (c) at any time during the continuance of any such default, upon the written request of the
Trustee, forthwith pay to the Trustee all sums so held in trust by such paying agent.

     The Issuer may at any time, for the purpose of obtaining the satisfaction and discharge of
this Indenture or for any other purpose, pay, or by Issuer Order direct any paying agent to pay, to
the Trustee all sums held in trust by the Issuer 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 Issuer 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 Issuer in trust
for the payment of the principal of and premium, if any, or interest on any Security and remaining
unclaimed for two years after such principal and premium, if any, or interest has become due and
payable shall be paid to the Issuer on Issuer Order, or, if then held by the Issuer, shall be
discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured
general creditor, look only to the Issuer for payment thereof, and all liability of the Trustee or
such paying agent with respect to such trust money, and all liability of the Issuer as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such paying agent, before
being required to make any such repayment, may (but shall not be obligated to), at the expense of
the Issuer, cause to be published at least once, in an Authorized Newspaper in the Borough of
Manhattan, The City of New York, and at least once in an Authorized Newspaper in London, 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 Issuer.

     Section 3.4 Statements of Officers of Issuer as to Default; Notice of Default. The
Issuer will deliver to the Trustee, within 120 days after the end of each fiscal year of the Issuer
ending after the date hereof, a certificate, signed by the Issuer’s principal executive officer,
principal financial officer or principal accounting officer, stating whether or not to the best
knowledge of the signer thereof the Issuer is in default (without regard to periods of grace or
requirements of notice provided hereunder) in the performance and observance of any of the terms,
provisions and conditions hereof, and if the Issuer shall be in default, specifying all such
defaults and the nature and status thereof of which such signer may have knowledge.

18

 

     Section 3.5
Existence. Subject to Article 9, the Issuer will do or cause to be done
all things necessary to preserve and keep in full force and effect its existence, rights (charter
and statutory) and franchises and those of each of its Subsidiaries; provided, however, that the
Issuer shall not be required to preserve any such right or franchise if its Board of Directors
shall determine that the preservation thereof is no longer desirable in the conduct of the business
of the Issuer or the business of any Subsidiary and that the loss thereof is not disadvantageous in
any material respect to the Holders.

     Section 3.6 Maintenance of Properties. The Issuer will cause all properties used or
useful in the conduct of its business or the business of any Subsidiary to be maintained and kept
in good condition, repair and working order and supplied with all necessary equipment and will
cause to be made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Issuer may be necessary so that the business carried on in
connection therewith may be properly and advantageously conducted at all times; provided, however,
that nothing in this Section shall prevent the Issuer from discontinuing the operation or
maintenance of any such properties if such discontinuance is, in the judgment of the Issuer,
desirable in the conduct of its business or the business of any Subsidiary and not disadvantageous
in any material respect to the Holders.

     Section 3.7 Payment of Taxes and Other Claims. The Issuer shall pay or discharge or
cause to be paid or discharged, before the same shall become delinquent, (1) all taxes, assessments
and governmental charges (including withholding taxes and any penalties, interest and additions to
taxes) levied or imposed upon the Issuer or any Subsidiary or upon the income, profits or property
of the Issuer or any Subsidiary, and (2) all material lawful claims for labor, materials and
supplies which, if unpaid, might by law become a lien upon the property of the Issuer or any
Subsidiary; provided, however, that the Issuer shall not be required to pay or discharge or cause
to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or
validity is being contested in good faith by appropriate proceedings and for which disputed amounts
adequate reserves have been made.

     Section 3.8 Further Instruments and Acts. Upon request of the Trustee, the Issuer
will execute and deliver such further instruments and perform such further acts as may be
reasonably necessary or proper to carry out more effectively the purposes of this Indenture.

     Section 3.9 [Reserved].

     Section 3.10 Luxembourg Publications. In the event of the publication of any notice
pursuant to Section 3.3, 5.11, 6.10, 6.11, 8.2 or 12.2, the party making such publication in the
Borough of Manhattan, The City of New York and London shall also, to the extent that notice is
required to be given to Holders of Securities of any series by applicable Luxembourg law or stock
exchange regulation, as evidenced by an Officer’s Certificate delivered to such party, make a
similar publication in Luxembourg.

     Section 3.11 Commission Reports. The Issuer shall file with the Trustee, within 15
days after it files such annual and quarterly reports, information, documents and other reports
with the Commission, copies of its annual report and of the information, documents and other
reports (or copies of such portions of any of the foregoing as the Commission may by rules and
regulations prescribe) which the Issuer is required to file with the Commission pursuant to Section
13 or 15(d) of the Securities Exchange Act of 1934. Delivery of such reports, information and
documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall
not constitute constructive notice of any information contained therein or determinable from
information contained therein, including the Issuer’s compliance with any of its covenants
hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates). The
Trustee shall be under no obligation to analyze or make any credit decisions with respect to
reports or other information received by it pursuant to this section, but shall hold such reports
and other information solely for the benefit of, and review by, the security holders.

     Section 3.12 Calculation of Original Issue Discount. The Issuer shall file with the
Trustee promptly at the end of each calendar year (i) a written notice specifying the amount of
original issue discount (including daily rates and accrual periods), if any, accrued on Outstanding
Securities, as of the end

19

 

of such year and (ii) such other specific information relating to such original issue discount
as may then be relevant under the Internal Revenue Code of 1986, as amended from time to time.

ARTICLE 4

SECURITYHOLDERS LISTS AND REPORTS BY THE ISSUER AND THE TRUSTEE 

     Section 4.1 Issuer to Furnish Trustee Information as to Names and Addresses of
Securityholders. If and so long as the Trustee shall not be the Security registrar for the
Securities of any series, the Issuer and any other obligor on the Securities will furnish or cause
to be furnished to the Trustee a list in such form as the Trustee may reasonably require of the
names and addresses of the Holders of the Registered Securities of such series pursuant to Section
312 of the Trust Indenture Act of 1939 (1) semi-annually not more than 5 days after each record
date for the payment of interest on such Registered Securities, as hereinabove specified, as of
such record date and on dates to be determined pursuant to Section 2.3 for non-interest bearing
Registered Securities in each year, and (2) at such other times as the Trustee may request in
writing, within thirty days after receipt by the Issuer of any such request as of a date not more
than 15 days prior to the time such information is furnished.

     Section 4.2 Preservation of Information; Communications to Holders.

     (a) 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 4.1 and the names and addresses of Holders received by the Trustee in its capacity as
Security registrar or paying agent. The Trustee may destroy any list furnished to it as provided
in Section 4.1 upon receipt of a new list so furnished.

     (b) 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 of 1939.

     (c) Every Holder of Securities, by receiving and holding the same, agrees with the Issuer and
the Trustee that neither the Issuer nor the Trustee nor any agent of any of them shall be held
accountable by reason of the disclosure of any such information as to the names and addresses of
the Holders in accordance with Sections 4.1 and 4.2(b), regardless of the source from which such
information was derived, and that the Trustee shall not be held accountable by reason of mailing
any material pursuant to a request made under Section 4.2(b).

     Section 4.3 Reports by the Trustee. Any Trustee’s report required under Section
313(a) of the Trust Indenture Act of 1939 shall be transmitted within 60 days after April 15 in
each year beginning 2009, as provided in Section 313(c) of the Trust Indenture Act of 1939, so long
as any Securities are Outstanding hereunder, and shall be dated as of such April 15.

     A copy of each such report shall, at the time of such transmission to Holders, be filed by the
Trustee with each stock exchange, if any, upon which the Securities are listed, with the Commission
and with the Issuer. The Issuer will promptly notify the Trustee when the Securities are listed on
any stock exchange and of any delisting thereof.

ARTICLE 5

REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS ON EVENT OF DEFAULT

     Section 5.1 Event of Default Defined; Acceleration of Maturity; Waiver of Default.
“Event of Default” with respect to Securities of any series wherever used herein, means each one of
the following events which shall have occurred and be continuing (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected by operation of
law or pursuant to any judgment,

20

 

decree or order of any court or any order, rule or regulation of any administrative or
governmental body) unless it is either inapplicable to a particular series or it is specifically
deleted or modified in an indenture supplemental hereto, if any, under which such series of
Securities is issued:

     (a) default in the payment of any installment of interest upon any of the Securities of such
series as and when the same shall become due and payable, and continuance of such default for a
period of 30 days and the interest payment date has not been properly extended or deferred;
provided, however, that if the Issuer is permitted by the terms of the Securities of the applicable
series to defer the payment in question, the date on which such payment is due and payable shall be
the date on which the Issuer is required to make payment following such deferral, if such deferral
has been elected pursuant to the terms of the Securities of that series (subject to any deferral of
any due date in the case of an Extension Period); or

     (b) default in the payment of all or any part of the principal of, or premium, if any, on any
of the Securities of such series as and when the same shall become due and payable either at
maturity, upon any redemption, by declaration or otherwise; provided, however, that if the Issuer
is permitted by the terms of the Securities of the applicable series to defer the payment in
question, the date on which such payment is due and payable shall be the date on which the Issuer
is required to make payment following such deferral, if such deferral has been elected pursuant to
the terms of the Securities of that series (subject to any deferral of any due date in the case of
an Extension Period); or

     (c) default in the payment of any sinking fund installment as and when the same shall become
due and payable by the terms of the Securities of such series; or

     (d) failure on the part of the Issuer duly to observe or perform any other of the covenants or
agreements on the part of the Issuer in the Securities of such series (other than a covenant or
agreement in respect of the Securities of such series a default in the performance or breach of
which is elsewhere in this Section specifically dealt with) or contained in this Indenture (other
than a covenant or agreement included in this Indenture solely for the benefit of a series of
Securities other than such series) for a period of 90 days after the date on which written notice
specifying such failure, stating that such notice is a “Notice of Default” hereunder and demanding
that the Issuer remedy the same, shall have been given by registered or certified mail, return
receipt requested, to the Issuer by the Trustee, or to the Issuer and the Trustee by the holders of
at least 25% in aggregate principal amount of the Outstanding Securities of all series affected
thereby; or

     (e) [Reserved]; or

     (f) the Issuer shall commence a voluntary case under any applicable bankruptcy, insolvency or
other similar law now or hereafter in effect, or consent to the entry of an order for relief in an
involuntary case under any such law, or consent to the appointment or taking possession by a
receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official) of the
Issuer or for any substantial part of its property, or make any general assignment for the benefit
of creditors or shall admit in writing its inability to pay its debts generally as they become due;
or

     (g) [Reserved]; or

     (h) any other Event of Default provided in the supplemental indenture under which such series
of Securities is issued or in the form of Security for such series.

     If an Event of Default (other than an Event of Default specified in Section 5.1(f)) with
respect to Securities of any series then Outstanding occurs and is continuing, then, and in each
and every such case, except for any series of Securities the principal of which shall have already
become due and payable, either the Trustee or the Holders of not less than 25% in aggregate
principal amount of the Securities of each such affected series then Outstanding hereunder (voting
as a single class) by notice in writing to the Issuer (and to the Trustee if given by
Securityholders), may declare the entire principal (or, if the Securities of any such affected
series are Original Issue Discount Securities, such portion of the

21

 

principal amount as may be specified in the terms of such series) of all Securities of all
such affected series, and the interest accrued thereon, if any, to be due and payable immediately,
and upon any such declaration, the same shall become immediately due and payable. If an Event of
Default specified in clause (f) occurs, all unpaid principal (or, if any Securities are Original
Issue Discount Securities, such portion of the principal as may be specified in the terms thereof)
of all the Securities then Outstanding, and interest accrued thereon, if any, shall be due and
payable immediately, without any declaration or other act on the part of the Trustee or any
Securityholder.

     The foregoing provisions, however, are subject to the condition that if, at any time after the
principal (or, if the Securities are Original Issue Discount Securities, such portion of the
principal as may be specified in the terms thereof) of the Securities of any series (or of all the
Securities, as the case may be) shall have been so declared due and payable, and before any
judgment or decree for the payment of the monies due shall have been obtained or entered as
hereinafter provided, the Issuer shall pay or shall deposit with the Trustee a sum sufficient to
pay all matured installments of interest upon all the Securities of such series (or of all the
Securities, as the case may be) and the principal of any and all Securities of each such series (or
of all the Securities, as the case may be) which shall have become due otherwise than by
acceleration (with interest upon such principal and, to the extent that payment of such interest is
enforceable under applicable law, on overdue installments of interest, at the same rate as the rate
of interest or Yield to Maturity (in the case of Original Issue Discount Securities) specified in
the Securities of each such series (or at the respective rates of interest or Yields to Maturity of
all the Securities, as the case may be) to the date of such payment or deposit) and such amount as
shall be sufficient to cover all amounts due to the Trustee, including reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and if any and all
Events of Default under the Indenture, other than the non-payment of the principal of Securities
which shall have become due by acceleration, shall have been cured, waived or otherwise remedied as
provided herein, then and in every such case the Holders of a majority in aggregate principal
amount of all the Securities of each such series, or of all the Securities, in each case voting as
a single class, then Outstanding, by written notice to the Issuer and to the Trustee, may waive all
defaults with respect to each such series (or with respect to all the Securities, as the case may
be) and rescind and annul such declaration and its consequences, but no such waiver or rescission
and annulment shall extend to or shall affect any subsequent default or shall impair any right
consequent thereon.

     For all purposes under this Indenture, if a portion of the principal of any Original Issue
Discount Securities shall have been accelerated and declared due and payable pursuant to the
provisions hereof, then, from and after such declaration, unless such declaration has been
rescinded and annulled, the principal amount of such Original Issue Discount Securities shall be
deemed, for all purposes hereunder, to be such portion of the principal thereof as shall be due and
payable as a result of such acceleration, and payment of such portion of the principal thereof as
shall be due and payable as a result of such acceleration, together with interest, if any, thereon
and all other amounts owing thereunder, shall constitute payment in full of such Original Issue
Discount Securities.

     Section 5.2 Collection of Indebtedness by Trustee; Trustee May Prove Debt. (a) The
Issuer covenants that (i) in case default shall be made in the payment of any installment of
interest on any of the Securities of any series when such interest shall have become due and
payable, and such default shall have continued for a period of
30 days or (ii) in case default shall
be made in the payment of all or any part of the principal of any of the Securities of any series
when the same shall have become due and payable, whether upon maturity of the Securities of such
series or upon any redemption or by declaration or otherwise, then upon demand of the Trustee, the
Issuer will pay to the Trustee for the benefit of the Holders of the Securities of such series the
whole amount that then shall have become due and payable on all Securities of such series, and such
Coupons, for principal or interest, as the case may be (with interest to the date of such payment
upon the overdue principal and, to the extent that payment of such interest is enforceable under
applicable law, on overdue installments of interest at the same rate as the rate of interest or
Yield to Maturity (in the case of Original Issue Discount Securities) specified in the Securities
of such series); and in addition thereto, such further amount as shall be sufficient to cover all
amounts due to the Trustee, including reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel.

22

 

     Until such demand is made by the Trustee, the Issuer may pay the principal of and interest on
the Securities of any series to the registered holders, whether or not the Securities of such
series be overdue.

     (b) In case the Issuer shall fail forthwith to pay such amounts upon such demand, the Trustee,
in its own name and as trustee of an express trust, shall be entitled and empowered to institute
any action or proceedings at law or in equity for the collection of the sums so due and unpaid, and
may prosecute any such action or proceedings to judgment or final decree, and may enforce any such
judgment or final decree against the Issuer or other obligor upon the Securities and collect in the
manner provided by law out of the property of the Issuer or other obligor upon the Securities,
wherever situated the monies adjudged or decreed to be payable.

     (c) In case there shall be pending proceedings relative to the Issuer or any other obligor
upon the Securities under Title 11 of the United States Code or any other applicable Federal or
state bankruptcy, insolvency or other similar law, or in case a receiver, assignee or trustee in
bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been
appointed for or taken possession of the Issuer or its property or such other obligor, or in case
of any other comparable judicial proceedings relative to the Issuer or other obligor upon the
Securities, or to the creditors or property of the Issuer or such other obligor, the Trustee,
irrespective of whether the principal of the Securities shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made
any demand pursuant to the provisions of this Section, shall be entitled and empowered, by
intervention in such proceedings or otherwise:

     (i) to file and prove a claim or claims for the whole amount of principal and interest
(or, if the Securities of any series are Original Issue Discount Securities, such portion
of the principal amount as may be specified in the terms of such series) owing and unpaid
in respect of the Securities of any series, and to file such other papers or documents as
may be necessary or advisable in order to have the claims of the Trustee (including any
claim for reasonable compensation, expenses, disbursements and advances of the Trustee, its
agents, and counsel) and of the Securityholders allowed in any judicial proceedings
relative to the Issuer or other obligor upon the Securities, or to the creditors or
property of the Issuer or such other obligor,

     (ii) unless prohibited by applicable law and regulations, to vote on behalf of the
holders of the Securities of any series in any election of a trustee or a standby trustee
in arrangement, reorganization, liquidation or other bankruptcy or insolvency proceedings
or person performing similar functions in comparable proceedings, and

     (iii) to collect and receive any monies or other property payable or deliverable on
any such claims, and to distribute all amounts received with respect to the claims of the
Securityholders and of the Trustee on their behalf; and any trustee, receiver, or
liquidator, custodian or other similar official is hereby authorized by each of the
Securityholders to make payments to the Trustee, and, in the event that the Trustee shall
consent to the making of payments directly to the Securityholders, to pay to the Trustee
such amounts as shall be sufficient to cover all amounts due to the Trustee, including
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents,
and counsel.

     Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to
or vote for or accept or adopt on behalf of any Securityholder any plan of reorganization,
arrangement, adjustment or composition affecting the Securities of any series or the rights of any
Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Securityholder
in any such proceeding except, as aforesaid, to vote for the election of a trustee in bankruptcy or
similar person.

     (d) All rights of action and of asserting claims under this Indenture, or under any of the
Securities of any series or Coupons appertaining to such Securities, may be enforced by the Trustee
without the possession of any of such Securities or Coupons or the production thereof in any trial
or other proceedings relative thereto, and any such action or proceedings instituted by the Trustee
shall be brought

23

 

in its own name as trustee of an express trust, and any recovery of judgment, subject to the
payment of all amounts due to the Trustee, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, shall be for the ratable benefit
of the Holders of the Securities or Coupons appertaining to such Securities in respect of which
such action was taken.

     (e) In any proceedings brought by the Trustee (and also any proceedings involving the
interpretation of any provision of this Indenture to which the Trustee shall be a party) the
Trustee shall be held to represent all the Holders of the Securities or Coupons appertaining to
such Securities in respect to which such action was taken, and it shall not be necessary to make
any Holders of such Securities or Coupons appertaining to such Securities parties to any such
proceedings.

     Section 5.3 Application of Proceeds. Any monies or property collected by the Trustee
pursuant to this Article, or distributable in respect of the Issuer’s obligations under this
Indenture, in respect of any series shall, subject to the subordination provisions hereof, be
applied in the following order at the date or dates fixed by the Trustee and, in case of the
distribution of such monies on account of principal or interest, upon presentation of the several
Securities and Coupons appertaining to such Securities in respect of which monies have been
collected and stamping (or otherwise noting) thereon the payment, or issuing Securities of such
series in reduced principal amounts in exchange for the presented Securities of like series if only
partially paid, or upon surrender thereof if fully paid:

     FIRST: To the payment of all amounts due to the Trustee under Section 6.6;

     SECOND: In case the principal of the Securities of such series in respect of which monies
have been collected shall not have become and be then due and payable, to the payment of interest
on the Securities of such series in default in the order of the maturity of the installments of
such interest, with interest (to the extent that such interest has been collected by the Trustee)
upon the overdue installments of interest at the same rate as the rate of interest or Yield to
Maturity (in the case of Original Issue Discount Securities) specified in such Securities, such
payments to be made ratably to the persons entitled thereto, without discrimination or preference;

     THIRD: In case the principal of the Securities of such series in respect of which monies have
been collected shall have become and shall be then due and payable, to the payment of the whole
amount then owing and unpaid upon all the Securities of such series for principal and interest,
with interest upon the overdue principal, and (to the extent that such interest has been collected
by the Trustee) upon overdue installments of interest at the same rate as the rate of interest or
Yield to Maturity (in the case of Original Issue Discount Securities) specified in the Securities
of such series; and in case such monies shall be insufficient to pay in full the whole amount so
due and unpaid upon the Securities of such series, then to the payment of such principal and
interest or Yield to Maturity, without preference or priority of principal over interest or Yield
to Maturity, or of interest or Yield to Maturity over principal, or of any installment of interest
over any other installment of interest, or of any Security of such series over any other Security
of such series, ratably to the aggregate of such principal and accrued and unpaid interest or Yield
to Maturity; and

     FOURTH: To the payment of the remainder, if any, to the Issuer or any other Person lawfully
entitled thereto.

     Section 5.4 Suits for Enforcement. In case an Event of Default has occurred, has not
been waived and is continuing, the Trustee may in its discretion proceed to protect and enforce the
rights vested in it by this Indenture by such appropriate judicial proceedings as the Trustee shall
deem most effectual to protect and enforce any of such rights, either at law or in equity or in
bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement
contained in this Indenture or in aid of the exercise of any power granted in this Indenture or to
enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

     Section 5.5 Restoration of Rights on Abandonment of Proceedings. In case the Trustee
shall have proceeded to enforce any right under this Indenture and such proceedings shall have been

24

 

discontinued or abandoned for any reason, or shall have been determined adversely to the
Trustee, then and in every such case the Issuer and the Trustee shall be restored respectively to
their former positions and rights hereunder, and all rights, remedies and powers of the Issuer, the
Trustee and the Securityholders shall continue as though no such proceedings had been taken.

     Section 5.6 Limitations on Suits by Securityholders. No Holder of any Security of any
series or of any Coupon appertaining thereto shall have any right by virtue or by availing of any
provision of this Indenture to institute any action or proceeding at law or in equity or in
bankruptcy or otherwise upon or under or with respect to this Indenture, or for the appointment of
a trustee, receiver, liquidator, custodian or other similar official or for any other remedy
hereunder, unless such Holder previously shall have given to the Trustee written notice of default
and of the continuance thereof, as hereinbefore provided, and unless also the Holders of not less
than 25% in aggregate principal amount of the Securities of each affected series then Outstanding
(treated as a single class) shall have made written request upon the Trustee to institute such
action or proceedings in its own name as trustee hereunder and shall have offered to the Trustee
such indemnity reasonably satisfactory to it against the costs, expenses and liabilities to be
incurred therein or thereby and the Trustee for 60 days after its receipt of such notice, request
and offer of indemnity shall have failed to institute any such action or proceeding and no
direction inconsistent with such written request shall have been given to the Trustee pursuant to
Section 5.9; it being understood and intended, and being expressly covenanted by the taker and
Holder of every Security or Coupon with every other taker and Holder and the Trustee, that no one
or more Holders of Securities of any series or Coupons appertaining to such Securities shall have
any right in any manner whatever by virtue or by availing of any provision of this Indenture to
affect, disturb or prejudice the rights of any other such Holder of Securities or Coupons
appertaining to such Securities, or to obtain or seek to obtain priority over or preference to any
other such Holder or to enforce any right under this Indenture, except in the manner herein
provided and for the equal, ratable and common benefit of all Holders of Securities of the
applicable series and Coupons appertaining to such Securities. For the protection and enforcement
of the provisions of this Section, each and every Securityholder and the Trustee shall be entitled
to such relief as can be given either at law or in equity.

     Section 5.7 Unconditional Right of Securityholders to Institute Certain Suits.
Notwithstanding any other provision in this Indenture and any provision of any Security, the right
of any Holder of any Security or Coupon to receive payment of the principal of and interest on such
Security or Coupon on or after the respective due dates expressed in such Security or Coupon, or to
institute suit for the enforcement of any such payment on or after such respective dates shall not
be impaired or affected without the consent of such Holder.

     Section 5.8 Powers and Remedies Cumulative; Delay or Omission Not Waiver of Default.
Except as provided in Section 5.6, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders of Securities or Coupons 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.

     No delay or omission of the Trustee or of any Holder of Securities or Coupons to exercise any
right or power accruing upon any Event of Default occurring and continuing as aforesaid shall
impair any such right or power or shall be construed to be a waiver of any such Event of Default or
an acquiescence therein; and, subject to Section 5.6, every power and remedy given by this
Indenture or by law to the Trustee or to the Holders of Securities or Coupons may be exercised from
time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders of
Securities or Coupons.

     Section 5.9 Control by Holders of Securities. The Holders of a majority in aggregate
principal amount of the Securities of each series affected (with all such series voting as a single
class) at the time Outstanding 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 by this Indenture; provided
that such direction shall not be otherwise than in accordance with law and the provisions of this
Indenture; provided further that (subject to

25

 

the provisions of Section 6.1) the Trustee shall have the right to decline to follow any such
direction if the Trustee, being advised by counsel, shall determine that the action or proceeding
so directed may not lawfully be taken or if the Trustee in good faith by its board of directors,
the executive committee, or a trust committee of directors or Responsible Officers of the Trustee
shall determine that the action or proceedings so directed would involve the Trustee in personal
liability or if the Trustee in good faith shall so determine that the actions or forbearances
specified in or pursuant to such direction would be unduly prejudicial to the interests of Holders
of the Securities of all series so affected not joining in the giving of said direction, it being
understood that (subject to Section 6.1) the Trustee shall have no duty to ascertain whether or not
such actions or forbearances are unduly prejudicial to such Holders.

     Nothing in this Indenture shall impair the right of the Trustee in its discretion to take any
action deemed proper by the Trustee and which is not inconsistent with such direction or directions
by Securityholders.

     Section 5.10 Waiver of Past Defaults. Prior to the acceleration of the maturity of
any Securities as provided in Section 5.1, the Holders of a majority in aggregate principal amount
of the Securities of all series at the time Outstanding with respect to which an Event of Default
shall have occurred and be continuing (voting as a single class) may on behalf of the Holders of
all such Securities waive any past default or Event of Default described in Section 5.1 and its
consequences, except a default in respect of a covenant or provision hereof which cannot be
modified or amended without the consent of the Holder of each Security affected. In the case of
any such waiver, the Issuer, the Trustee and the Holders of all such Securities shall be restored
to their former positions and rights hereunder, respectively; but no such waiver shall extend to
any subsequent or other default or impair any right consequent thereon.

     Upon any such waiver, such default shall cease to exist and be deemed to have been cured and
not to have occurred, and any Event of Default arising therefrom shall be deemed to have been
cured, and not to have occurred for every purpose of this Indenture; but no such waiver shall
extend to any subsequent or other default or Event of Default or impair any right consequent
thereon.

     Section 5.11 Trustee to Give Notice of Default, but May Withhold in Certain
Circumstances. The Trustee shall, within ninety days after the occurrence of a default with
respect to the Securities of any series, give notice of all defaults with respect to that series
actually known to a Responsible Officer of the Trustee (1) if any Unregistered Securities of that
series are then Outstanding, to the Holders thereof, by publication at least once in an Authorized
Newspaper in the Borough of Manhattan, The City of New York and at least once in an Authorized
Newspaper in London (and, if required by Section 3.10, at least once in an Authorized Newspaper in
Luxembourg) and (2) to all Holders of Securities of such series in the manner and to the extent
provided in Section 313(c) of the Trust Indenture Act of 1939, unless in each case such defaults
shall have been cured before the mailing or publication of such notice (the term “defaults” for the
purpose of this Section being hereby defined to mean any event or condition which is, or with
notice or lapse of time or both would become, an Event of Default); provided that, except in the
case of default in the payment of the principal of or interest on any of the Securities of such
series, or in the payment of any sinking fund installment on such series, the Trustee shall be
protected in withholding such notice if and so long as the board of directors, the executive
committee, or a trust committee of directors or trustees and/or Responsible Officers of the Trustee
in good faith determines that the withholding of such notice is in the interests of the
Securityholders of such series.

     Section 5.12 Right of Court to Require Filing of Undertaking to Pay Costs. All
parties to this Indenture agree, and each Holder of any Security or Coupon by his or her acceptance
thereof shall be deemed to have agreed, that any court may in its discretion require, 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, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any
party litigant in such suit, having due regard to the merits and good faith of the claims or
defenses made by such party litigant; but the provisions of this Section shall not be deemed to
authorize any court to require such an undertaking or to make such an assessment in any suit
instituted by the Issuer.

26

 

ARTICLE 6

CONCERNING THE TRUSTEE

     Section 6.1 Duties and Responsibilities of the Trustee; During Default; Prior to
Default. (a) With respect to any series of Securities issued hereunder, the Trustee, prior to
the occurrence of an Event of Default with respect to the Securities of a particular series and
after the curing or waiving of all Events of Default which may have occurred with respect to such
series, undertakes to perform such duties and only such duties as are specifically set forth in
this Indenture with respect to such series and no implied covenants or obligations shall be read
into this Indenture against the Trustee. In case an Event of Default with respect to the
Securities of a series has occurred (which has not been cured or waived) the Trustee shall exercise
with respect to such series of Securities such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a prudent person would
exercise or use under the circumstances in the conduct of his or her own affairs.

     (b) No provision of this Indenture shall be construed to relieve the Trustee from liability
for its own negligent action, its own negligent failure to act or its own willful misconduct,
except that

     (i) prior to the occurrence of an Event of Default with respect to the Securities of
any series and after the curing or waiving of all such Events of Default with respect to
such series which may have occurred:

                    (1) the duties and obligations of the Trustee with respect to the Securities
of any series shall be determined solely by the express provisions of this
Indenture, and the Trustee shall not be liable except for the performance of such
duties and obligations as are specifically set forth in this Indenture, and no
implied covenants or obligations shall be read into this Indenture against the
Trustee; and

                    (2) in the absence of bad faith on the part of the Trustee, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon any statements, certificates or opinions
furnished to the Trustee and conforming to the requirements of this Indenture; but
in the case of any such statements, certificates or opinions which by any
provision hereof are specifically required to be furnished to the Trustee, the
Trustee shall be under a duty to examine the same to determine whether or not they
conform to the requirements of this Indenture (but need not confirm or investigate
the accuracy of mathematical calculations or other facts stated therein, unless
specifically required by this Indenture);

     (ii) the Trustee shall not be liable for any error of judgment made in good faith by a
Responsible Officer or Responsible Officers of the Trustee, unless it shall be proved that
the Trustee was negligent in ascertaining the pertinent facts;

     (iii) the Trustee shall not be liable with respect to any action taken or omitted to
be taken by it in good faith in accordance with the direction of the Holders pursuant to
Section 5.9 relating to the time, method and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred upon the
Trustee, under this Indenture; and

     (iv) the Trustee shall not be required to take notice, and shall not be deemed to have
notice, of any default or Event of Default hereunder, except, if the Trustee is at the time
acting as paying agent in respect of the applicable series of Securities, Events of Default
described in paragraphs (1), (2) and (3) of Section 5.1 hereof, unless a Responsible
Officer of the Trustee shall be notified specifically of the default or Event of Default on
a written instrument or document delivered to it at its notice address by the Issuer or by
the Holders of at least 10% of the aggregate principal amount of Securities then
outstanding. In the absence of delivery of notice satisfying those requirements, the
Trustee may assume conclusively that there is no default or Event of Default, except as
otherwise noted herein.

27

 

     (c) None of the provisions contained in this Indenture shall require the Trustee to expend or
risk its own funds or otherwise incur financial liability in the performance of any of its duties
or in the exercise of any of its rights or powers, if it shall have reasonable grounds for
believing that the repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

     The provisions of this Section 6.1 are in furtherance of and subject to Section 315 of the
Trust Indenture Act of 1939. 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 6.1

     Section 6.2 Certain Rights of the Trustee. In furtherance of and subject to the Trust
Indenture Act of 1939, and subject to Section 6.1:

     (a) the Trustee may conclusively rely, as to the truth of the statements and the correctness
of the opinions expressed therein, and shall be protected in acting or refraining from acting upon
any resolution, Officer’s Certificate or any other certificate, statement, instrument, opinion,
report, notice, request, consent, order, bond, debenture, note, coupon, security or other paper or
document believed by it to be genuine and to have been signed or presented by the proper party or
parties;

     (b) any request, direction, order or demand of the Issuer mentioned herein shall be
sufficiently evidenced by an Issuer Order (unless other evidence in respect thereof be herein
specifically prescribed); and any resolution of the Board of Directors may be evidenced to the
Trustee by a Board Resolution;

     (c) the Trustee may consult with legal counsel of its choice, and the advice of such counsel
or any Opinion of Counsel shall be full and complete authorization and protection in respect of any
action taken, suffered or omitted to be taken by it hereunder in good faith and reliance thereon;

     (d) the Trustee shall be under no obligation to exercise any of the trusts or powers vested in
it by this Indenture at the request, order or direction of any of the Securityholders pursuant to
the provisions of this Indenture, unless such Securityholders shall have offered to the Trustee
security or indemnity reasonably satisfactory to the Trustee against the costs, expenses and
liabilities which might be incurred therein or thereby;

     (e) the Trustee shall not be liable for any action taken or omitted by it in good faith and
believed by it to be authorized or within the discretion, rights or powers conferred upon it by
this Indenture;

     (f) [Reserved];

     (g) 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 such agent or attorney appointed
with due care by it hereunder;

     (h) the rights, privileges, protections, immunities and benefits given to the Trustee,
including, without limitation, its right to be indemnified, are extended to, and shall be
enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and
other Person employed to act hereunder;

     (i) the Trustee may request that the Issuer deliver an Officer’s Certificate setting forth the
names of individuals and/or titles of officers authorized at such time to take specified actions
pursuant to this Indenture, which Officer’s Certificate may be signed by any person authorized to
sign an Officer’s Certificate, including any person specified as so authorized in any such
certificate previously delivered and not superseded;

28

 

     (j) 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 Issuer, at a
time reasonably determined by the Issuer, personally or by agent or attorney at the sole cost of
the Issuer and shall incur no liability or additional liability of any kind by reason of such
inquiry or investigation;

     (k) 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, conclusively rely upon an Officer’s Certificate;

     (l) anything in this Indenture notwithstanding, in no event shall the Trustee be liable for
special, indirect, punitive or consequential loss or damage of any kind whatsoever (including but
not limited to loss of profit), even if the Trustee has been advised as to the likelihood of such
loss or damage and regardless of the form of action; and

     (m) the Trustee shall not be responsible or liable for any failure or delay in the performance
of its obligations under this Indenture arising out of or caused, directly or indirectly, by
circumstances beyond its control, including, without limitation, acts of God; earthquakes; fire;
flood; terrorism; wars and other military disturbances; sabotage; epidemics; riots; interruptions;
loss or malfunctions of utilities; computer (hardware or software) or communication services;
accidents; labor disputes; acts of civil or military authority and governmental action.

     Section 6.3 Trustee Not Responsible for Recitals, Disposition of Securities or Application
of Proceeds Thereof. The recitals contained herein and in the Securities or Coupons, except
the Trustee’s certificates of authentication, shall be taken as the statements of the Issuer, and
the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no
representation as to the validity or sufficiency of this Indenture or of any Securities or Coupons.
The Trustee shall not be accountable for the use or application by the Issuer of any of the
Securities or of the proceeds thereof.

     Section 6.4 Trustee and Agents May Hold Securities or Coupons; Collections, Etc. The
Trustee or any agent of the Issuer or the Trustee, in its individual or any other capacity, may
become the owner or pledgee of Securities or Coupons with the same rights it would have if it were
not the Trustee or such agent and may otherwise deal with the Issuer and receive, collect, hold and
retain collections from the Issuer with the same rights it would have if it were not the Trustee or
such agent.

     Section 6.5 Monies Held by Trustee. Subject to the provisions of Section 3.3 hereof,
all monies received by the Trustee shall, until used or applied as herein provided, be held in
trust for the purposes for which they were received, but need not be segregated from other funds
except to the extent required by mandatory provisions of law. Neither the Trustee nor any agent of
the Issuer or the Trustee shall be under any liability for interest on any monies received by it
hereunder.

     Section 6.6 Compensation and Indemnification of Trustee and its Prior Claim. The
Issuer covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be
entitled to, such compensation as shall be agreed in writing between the Issuer and the Trustee
from time to time (which shall not be limited by any provision of law in regard to the compensation
of a trustee of an express trust) and the Issuer covenants and agrees to pay or reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made
by or on behalf of the Trustee accordance with any of the provisions of this Indenture (including
the reasonable compensation and the expenses and disbursements of its counsel and of all agents and
other persons not regularly in its employ) except any such expense, disbursement or advance as may
arise from its negligence, bad faith or willful misconduct. The Issuer also covenants to indemnify
the Trustee and its directors, officers, employees, and agents (the “indemnitees”) for, and to hold
the indemnitees harmless against, any and all loss, liability, claim, damage,

29

 

penalty, fine or expense, including reasonable out-of-pocket expenses, reasonable incidental
expenses and reasonable legal fees and expenses incurred without negligence, bad faith or willful
misconduct on the indemnitees’ part, arising out of or in connection with the acceptance or
administration of this Indenture or the trusts hereunder and the indemnitees’ duties hereunder,
including the costs and expenses of defending themselves against or investigating any claim,
whether asserted by the Issuer or any Holder or any other Person, or liability in connection with
the exercise or performance of the indemnitees’ duties or obligations hereunder. The obligations
of the Issuer under this Section to compensate and indemnify the indemnitees and to pay or
reimburse the indemnitees for expenses, disbursements and advances shall constitute additional
indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture. Such
additional indebtedness shall be a senior claim to that of the Securities upon all property and
funds held or collected by the Trustee as such, except funds held in trust for the benefit of the
Holders of particular Securities or Coupons, and the Securities are hereby subordinated to such
senior claim.

     When the Trustee incurs expenses or renders services in connection with an Event of Default
specified in Section 5.1(f), 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.
For purposes of this Section 6.6, the term “Trustee” shall also include any predecessor Trustee.

     Section 6.7 [Reserved].

     Section 6.8 Indentures Not Creating Potential Conflicting Interests for the Trustee.
The following indentures are hereby specifically described for the purposes of Section 310(b)(1) of
the Trust Indenture Act of 1939: this Indenture with respect to the Securities of any series.

     Section 6.9 Persons Eligible for Appointment as Trustee. The Trustee for each series
of Securities hereunder shall at all times be a corporation or banking association organized and
doing business under the laws of the United States of America or of any State or the District of
Columbia having a combined capital and surplus of at least $50,000,000, and which is authorized
under such laws to exercise corporate trust powers and is subject to supervision or examination by
Federal, State or District of Columbia authority. Such corporation or banking association shall
have a place of business or an affiliate with a place of business in the Borough of Manhattan, The
City of New York if there be such a corporation or association in such location willing to act upon
reasonable and customary terms and conditions. If such corporation or association publishes
reports of condition at least annually, pursuant to law or to the requirements of the aforesaid
supervising or examining authority, then for the purposes of this Section, the combined capital and
surplus of such corporation or association shall be deemed to be its combined capital and surplus
as set forth in its most recent report of condition so published. In case at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, the Trustee shall
resign immediately in the manner and with the effect specified in Section 6.10.

     The provisions of this Section 6.9 are in furtherance of and subject to Section 310(a) of the
Trust Indenture Act of 1939.

     Section 6.10 Resignation and Removal; Appointment of Successor Trustee. (a) The
Trustee, or any trustee or trustees hereafter appointed, may at any time resign with respect to one
or more or all series of Securities by giving written notice of
resignation to the Issuer and (i)
if any Unregistered Securities of a series affected are then Outstanding, by giving notice of such
resignation to the Holders thereof, by publication, at the Issuer’s expense, at least once in an
Authorized Newspaper in the Borough of Manhattan, The City of New York, and at least once in an
Authorized Newspaper in London (and, if required by Section 3.10, at least once in an Authorized
Newspaper in Luxembourg), (ii) if any Unregistered Securities of a series affected are then
Outstanding, by mailing notice of such resignation to the Holders thereof who have filed their
names and addresses with the Trustee pursuant to Section 313(c)(2) of the Trust Indenture Act of
1939 at such addresses as were so furnished to the Trustee and (iii) by mailing notice of such
resignation to the Holders of then Outstanding Registered Securities of each series affected at
their addresses as they shall appear on the registry books. Upon receiving such notice of
resignation, the Issuer shall promptly appoint a successor Trustee or Trustees with respect to the
applicable series by

30

 

written instrument in duplicate, executed by authority of the Board of Directors, one copy of
which instrument shall be delivered to the resigning Trustee and one copy to the successor Trustee
or Trustees. If no successor Trustee shall have been so appointed with respect to any series and
have accepted appointment within 30 days after the mailing of such notice of resignation, the
resigning Trustee may petition, at the Issuer’s expense, any court of competent jurisdiction for
the appointment of a successor Trustee, or any Securityholder who has been a bona fide Holder of a
Security or Securities of the applicable series for at least six months may, subject to the
provisions of Section 5.12, on behalf of himself or herself and all others similarly situated,
petition any such court for the appointment of a successor Trustee. Such court may thereupon,
after such notice, if any, as it may deem proper and prescribe, appoint a successor Trustee.

     (b) In case at any time any of the following shall occur:

     (i) the Trustee shall fail to comply with the provisions of Section 310(b) of the
Trust Indenture Act of 1939 with respect to any series of Securities after written request
therefor by the Issuer or by any Securityholder who has been a bona fide Holder of a
Security or Securities of such series for at least six months; or

     (ii) the Trustee shall cease to be eligible in accordance with the provisions of
Section 6.9 and Section 310(a) of the Trust Indenture Act of 1939 and shall fail to resign
after written request therefor by the Issuer or by any Securityholder; or

     (iii) the Trustee shall become incapable of acting with respect to any series of
Securities, or shall be adjudged bankrupt or insolvent, or a receiver or liquidator 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, the Issuer may remove the Trustee with respect to the applicable series of
Securities and appoint a successor Trustee for such series by written instrument, in duplicate,
executed by order of the Board of Directors of the Issuer, one copy of which instrument shall be
delivered to the Trustee so removed and one copy to the successor Trustee, or, subject to the
provisions of Section 315(e) of the Trust Indenture Act of 1939, any Securityholder who has been a
bona fide Holder of a Security or Securities of such series for at least six months may on behalf
of himself or herself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor Trustee with respect
to such series. Such court may thereupon, after such notice, if any, as it may deem proper, remove
the Trustee and appoint a successor Trustee.

     (c) The Holders of a majority in aggregate principal amount of the Securities of each series
at the time Outstanding may at any time remove the Trustee with respect to Securities of such
series and appoint a successor Trustee with respect to the Securities of such series by delivering
to the Trustee so removed, to the successor Trustee so appointed and to the Issuer the evidence
provided for in Section 7.1 of the action in that regard taken by such Securityholders.

     (d) Any resignation or removal of the Trustee with respect to any series and any appointment
of a successor Trustee with respect to such series pursuant to any of the provisions of this
Section 6.10 shall become effective upon acceptance of appointment by the successor Trustee as
provided in Section 6.11.

     Section 6.11 Acceptance of Appointment by Successor Trustee. Any successor Trustee
appointed as provided in Section 6.10 shall execute and deliver to the Issuer and to the retiring
Trustee an instrument accepting such appointment hereunder, and thereupon the resignation or
removal of the retiring Trustee with respect to all or any applicable series shall become
effective and such successor Trustee, without any further act, deed or conveyance, shall become
vested with all rights, powers, duties and obligations with respect to such series of its
predecessor hereunder, with like effect as if originally named as Trustee for such series
hereunder; but, nevertheless, on the written request of the Issuer or of the successor Trustee,
upon payment of its charges then unpaid, the Trustee ceasing to act shall, subject to Section 3.3,
pay over to the successor Trustee all monies at the time held by it hereunder and shall execute

31

 

and deliver an instrument transferring to such successor trustee all such rights, powers,
duties and obligations. Upon request of any such successor Trustee, the Issuer shall execute any
and all instruments in writing for more fully and certainly vesting in and confirming to such
successor Trustee all such rights and powers. Any Trustee ceasing to act shall, nevertheless,
retain a prior claim upon all property or funds held or collected by such Trustee to secure any
amounts then due it pursuant to the provisions of Section 6.6.

     If a successor Trustee is appointed with respect to the Securities of one or more (but not
all) series, the Issuer, the retiring Trustee and each successor Trustee with respect to the
Securities of any applicable series shall execute and deliver an indenture supplemental hereto
which 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 any
series as to which the retiring Trustee is not retiring shall continue to be vested in the
retiring Trustee, and 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 under separate indentures.

     No successor Trustee with respect to any series of Securities shall accept appointment as
provided in this Section 6.11 unless at the time of such acceptance such successor Trustee shall be
qualified under Section 310(b) of the Trust Indenture Act of 1939 and eligible under the provisions
of Section 6.9.

     Upon acceptance of appointment by any successor Trustee as provided in this Section 6.11, the
Issuer shall give notice thereof (1) if any Unregistered Securities of a series affected are then
Outstanding, to the Holders thereof, by publication of such notice at least once in an Authorized
Newspaper in the Borough of Manhattan, The City of New York, and at least once in an Authorized
Newspaper in London (and, if required by Section 3.10, at least once in an Authorized Newspaper in
Luxembourg) and (2) if any Unregistered Securities of a series affected are then Outstanding, to
the Holders thereof who have filed their names and addresses with the Trustee pursuant to Section
313(c)(2) of the Trust Indenture Act of 1939, by mailing such notice to such Holders at such
addresses as were so furnished to the Trustee (and the Trustee shall make such information
available to the Issuer for such purpose) and (3) if any Registered Securities of a series affected
are then Outstanding, to the Holders thereof, by mailing such notice to such Holders at their
addresses as they shall appear on the registry books. If the acceptance of appointment is
substantially contemporaneous with the resignation, then the notice called for by the preceding
sentence may be combined with the notice called for by Section 6.10. If the Issuer fails to give
such notice within ten days after acceptance of appointment by the successor Trustee, the successor
Trustee shall cause such notice to be given at the expense of the Issuer.

     Section 6.12 Merger, Conversion, Consolidation or Succession to Business of Trustee.
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
that such corporation shall be qualified under Section 310(b) of the Trust Indenture Act of 1939
and eligible under the provisions of Section 6.9, without the execution or filing of any paper or
any further act on the part of any of the parties hereto, anything herein to the contrary
notwithstanding.

     In case at the time such successor to the Trustee shall succeed to the trusts created by this
Indenture any of the Securities of any series shall have been authenticated but not delivered, any
such successor to the Trustee may adopt such certificate of authentication and deliver such
Securities so authenticated; and, in case at that time any of the Securities of any series shall
not have been authenticated, any successor to the Trustee may authenticate such Securities either
in the name of any predecessor hereunder or in the name of the successor Trustee; and in all such
cases such certificate shall have the full force which it is anywhere in the Securities of such
series or in this Indenture provided that the certificate of the Trustee shall have; provided, that
the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate
Securities of any series in the name of any predecessor Trustee shall apply only to its successor
or successors by merger, conversion or consolidation.

32

 

     Section 6.13 Preferential Collection of Claims Against the Issuer. The Trustee shall
comply with Section 311(a) of the Trust Indenture Act of 1939, excluding any creditor relationship
listed in Section 311(b) of the Trust Indenture Act of 1939. A Trustee who has resigned or been
removed shall be subject to Section 311(a) of the Trust Indenture Act of 1939 to the extent
indicated therein.

     Section 6.14 Appointment of Authenticating Agent. As long as any Securities of a
series remain Outstanding, the Trustee may, by an instrument in writing, appoint with the approval
of the Issuer an authenticating agent (the “Authenticating Agent”) which shall be authorized to act
on behalf of the Trustee to authenticate Securities, including Securities issued upon exchange,
registration of transfer, partial redemption or pursuant to Section 2.9. Securities of each such
series authenticated by such Authenticating Agent shall be entitled to the benefits of this
Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee.
Whenever reference is made in this Indenture to the authentication and delivery of Securities of
any series by the Trustee or to 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 for such series and a Certificate of Authentication executed on behalf of the Trustee by such
Authenticating Agent. Such Authenticating Agent shall at all times be a corporation organized and
doing business under the laws of the United States of America or of any State, authorized under
such laws to exercise corporate trust powers, having a combined capital and surplus of at least
$50,000,000 (determined as provided in Section 6.9 with respect to the Trustee) and subject to
supervision or examination by Federal or State authority.

     Any corporation into which any Authenticating Agent may be merged or converted, or with which
it may be consolidated, or any corporation resulting from any merger or conversion or consolidation
to which any Authenticating Agent shall be a party, or any corporation succeeding to all or
substantially all the corporate agency business of any Authenticating Agent, shall continue to be
the Authenticating Agent with respect to all series of Securities for which it served as
Authenticating Agent without the execution or filing of any paper or any further act on the part of
the Trustee or such Authenticating Agent. Any Authenticating Agent may at any time, and if it
shall cease to be eligible shall, resign by giving written notice of resignation to the Trustee and
to the Issuer.

     Upon receiving such a notice of resignation or upon such a termination, or in case at any time
any Authenticating Agent shall cease to be eligible in accordance with the provisions of this
Section 6.14 with respect to one or more series of Securities, the Trustee shall upon receipt of an
Issuer Order appoint a successor Authenticating Agent and the Issuer shall provide notice of such
appointment to all Holders of Securities of such series in the manner and to the extent provided in
Section 11.4. Any successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all rights, powers, duties and responsibilities of its predecessor
hereunder, with like effect as if originally named as Authenticating Agent. The Trustee agrees to
pay to the Authenticating Agent for such series from time to time reasonable compensation. The
Authenticating Agent for the Securities of any series shall have no responsibility or liability for
any action taken by it as such at the direction of the Trustee.

     Sections 6.2, 6.3, 6.4, 6.6 and 7.3 shall be applicable to any Authenticating Agent.

ARTICLE 7

CONCERNING THE SECURITYHOLDERS

     Section 7.1 Evidence of Action Taken by Securityholders. Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by this Indenture to be
given or taken by a specified percentage in principal amount of the Securityholders of any or all
series may be embodied in and evidenced by one or more instruments of substantially similar tenor
signed by such specified percentage of Securityholders in person or by 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. Proof of execution of any
instrument or of a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Sections 6.1 and 6.2) conclusive in favor of the Trustee and the Issuer,
if made in the manner provided in this Article.

33

 

     Section 7.2 Proof of Execution of Instruments and of Holding of Securities. Subject
to Sections 6.1 and 6.2, the execution of any instrument by a Securityholder or his or her agent or
proxy may be proved in the following manner:

     (a) The fact and date of the execution by any Holder of any instrument may be proved by the
certificate of any notary public or other officer of any jurisdiction authorized to take
acknowledgments of deeds or administer oaths that the person executing such instruments
acknowledged to him or her the execution thereof, or by an affidavit of a witness to such execution
sworn to before any such notary or other such officer. Where such execution is by or on behalf of
any legal entity other than an individual, such certificate or affidavit shall also constitute
sufficient proof of the authority of the person executing the same.

     (b) The fact of the holding by any Holder of an Unregistered Security of any series, and the
identifying number of such Security and the date of his or her holding the same, may be proved by
the production of such Security or by a certificate executed by any trust company, bank, banker or
recognized securities dealer wherever situated satisfactory to the Trustee, if such certificate
shall be deemed by the Trustee to be satisfactory. Each such certificate shall be dated and shall
state that on the date thereof a Security of such series bearing a specified identifying number was
deposited with or exhibited to such trust company, bank, banker or recognized securities dealer by
the person named in such certificate. Any such certificate may be issued in respect of one or more
Unregistered Securities of one or more series specified therein. The holding by the person named
in any such certificate of any Unregistered Securities of any series specified therein shall be
presumed to continue for a period of one year from the date of such certificate unless at the time
of any determination of such holding (i) another certificate bearing a later date issued in respect
of the same Securities shall be produced, or (ii) the Securities of such series specified in such
certificate shall be produced by some other person, or (iii) the Securities of such series specified
in such certificate shall have ceased to be Outstanding. Subject to Sections 6.1 and 6.2, the fact
and date of the execution of any such instrument and the amount and numbers of Securities of any
series held by the person so executing such instrument and the amount and numbers of any Security
or Securities for such series may also be proven in accordance with such reasonable rules and
regulations as may be prescribed by the Trustee for such series or in any other manner which the
Trustee for such series may deem sufficient.

     (c) In the case of Registered Securities, the ownership of such Securities shall be proved by
the Security register or by a certificate of the Security registrar.

     The Issuer may set a record date for purposes of determining the identity of Holders of
Registered Securities of any series entitled to vote or consent to any action referred to in
Section 7.1, which record date may be set at any time or from time to time by notice to the
Trustee, for any date or dates (in the case of any adjournment or reconsideration) not more than 60
days nor less than five days prior to the proposed date of such vote or consent, and thereafter,
notwithstanding any other provisions hereof, with respect to Registered Securities of any series,
only Holders of Registered Securities of such series of record on such record date shall be
entitled to so vote or give such consent or revoke such vote or consent.

     Section 7.3 Holders to Be Treated as Owners. The Issuer, the Trustee and any agent of
the Issuer or the Trustee may deem and treat the person in whose name any Security shall be
registered upon the Security register for such series as the absolute owner of such Security
(whether or not such Security shall be overdue and notwithstanding any notation of ownership or
other writing thereon) for the purpose of receiving payment of or on account of the principal of
and, subject to the provisions of this Indenture, interest on such Security and for all other
purposes; and neither the Issuer nor the Trustee nor any agent of the Issuer or the Trustee shall
be affected by any notice to the contrary. The Issuer, the Trustee and any agent of the Issuer or
the Trustee may treat the Holder of any Unregistered Security and the Holder of any Coupon as the
absolute owner of such Unregistered Security or Coupon (whether or not such Unregistered Security
or Coupon shall be overdue) for the purpose of receiving payment thereof or on account thereof and
for all other purposes and neither the Issuer, the Trustee, nor any agent of the Issuer or the
Trustee shall be affected by any notice to the contrary. All such payments so made to any such
person, or upon his or her order, shall be valid, and, to the extent of the sum or sums so paid,
effectual to satisfy and discharge the liability for monies payable upon any such Unregistered
Security or Coupon.

34

 

     Section 7.4 Securities Owned by Issuer Deemed Not Outstanding. In determining whether
the Holders of the requisite aggregate principal amount of Outstanding Securities of any or all
series have concurred in any direction, consent or waiver under this Indenture, Securities which
are owned by the Issuer or any other obligor on the Securities with respect to which such
determination is being made or by any person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Issuer or any other obligor on the Securities with
respect to which such determination is being made shall be disregarded and deemed not to be
Outstanding for the purpose of any such determination, except that for the purpose of determining
whether the Trustee shall be protected in relying on any such direction, consent or waiver only
Securities which a Responsible Officer of the Trustee actually knows are so owned shall be so
disregarded. Securities so owned which have been pledged in good faith may be regarded as
Outstanding if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to
act with respect to such Securities and that the pledgee is not the Issuer or any other obligor
upon the Securities or any person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Issuer or any other obligor on the Securities. In case
of a dispute as to such right, the advice of counsel shall be full protection in respect of any
decision made by the Trustee in accordance with such advice. Upon request of the Trustee, the
Issuer shall furnish to the Trustee promptly an Officer’s Certificate listing and identifying all
Securities, if any, known by the Issuer to be owned or held by or for the account of any of the
above-described Persons; and, subject to Sections 6.1 and 6.2, the Trustee shall be entitled to
accept such Officer’s Certificate as conclusive evidence of the facts therein set forth and of the
fact that all Securities not listed therein are Outstanding for the purpose of any such
determination.

     Section 7.5 Right of Revocation of Action Taken. At any time prior to (but not after)
the evidencing to the Trustee, as provided in Section 7.1, of the taking of any action by the
Holders of the percentage in aggregate principal amount of the Securities of any or all series, as
the case may be, specified in this Indenture in connection with such action, any Holder of a
Security the serial number of which is shown by the evidence to be included among the serial
numbers of the Securities the Holders of which have consented to such action may, by filing written
notice at the Corporate Trust Office and upon proof of holding as provided in this Article, revoke
such action so far as concerns such Security. Except as aforesaid any such action taken by the
Holder of any Security shall be conclusive and binding upon such Holder and upon all future Holders
and owners of such Security and of any Securities issued in exchange or substitution therefor or on
registration of transfer thereof, irrespective of whether or not any notation in regard thereto is
made upon any such Security. Any action taken by the Holders of the percentage in aggregate
principal amount of the Securities of any or all series, as the case may be, specified in this
Indenture in connection with such action shall be conclusively binding upon the Issuer, the Trustee
and the Holders of all the Securities affected by such action.

ARTICLE 8

SUPPLEMENTAL INDENTURES

     Section 8.1 Supplemental Indentures Without Consent of Securityholders. (a) In
addition to any supplemental indenture otherwise authorized by this Indenture, the Issuer, when
authorized by a resolution of its Board of Directors (which resolution may provide general terms or
parameters for such action and may provide that the specific terms of such action may be determined
in accordance with or pursuant to an Issuer Order), and the Trustee may from time to time and at
any time enter into an indenture or indentures supplemental hereto which comply with the Trust
Indenture Act of 1939, as then in effect, without the consent of the Holders, for one or more of
the following purposes:

     (i) to convey, transfer, assign, mortgage or pledge to the Trustee as security for the
Securities of one or more series any property or assets;

     (ii) to evidence the succession of another Person to the Issuer, or successive
successions, and the assumption by the successor Person of the covenants, agreements and
obligations of the Issuer pursuant to Article 9;

35

 

     (iii) to add to the covenants of the Issuer such further covenants, restrictions,
conditions or provisions as the Issuer and the Trustee shall consider to be for the
protection of the Holders of Securities or Coupons, and to make the occurrence, or the
occurrence and continuance, of a default in any such additional covenants, restrictions,
conditions or provisions an Event of Default permitting the enforcement of all or any of
the several remedies provided in this Indenture as herein set forth; provided, that in
respect of any such additional covenant, restriction, condition or provision such
supplemental indenture may provide for a particular period of grace after default (which
period may be shorter or longer than that allowed in the case of other defaults) or may
provide for an immediate enforcement upon such an Event of Default or may limit the
remedies available to the Trustee upon such an Event of Default or may limit the right of
the Holders of a majority in aggregate principal amount of the Securities of such series to
waive such an Event of Default;

     (iv) to cure any ambiguity or to correct or supplement any provision contained herein
or in any supplemental indenture which may be defective or inconsistent with any other
provision contained herein or in any supplemental indenture, or to make any other
provisions as the Issuer may deem necessary or desirable, provided that no such action
shall adversely affect the interests of the Holders of the Securities or Coupons;

     (v) to establish the forms or terms of Securities of any series or of the Coupons
appertaining to such Securities as permitted by Sections 2.1 and 2.3; and

     (vi) to evidence and provide for the acceptance of appointment hereunder by a
successor Trustee with respect to the Securities of one or more series and to 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, pursuant to
the requirements of Section 6.11.

     (b) The Trustee is hereby authorized to join with the Issuer in the execution of any such
supplemental indenture, to make any further appropriate agreements and stipulations which may be
therein contained and to accept the conveyance, transfer, assignment, mortgage or pledge of any
property thereunder, but the Trustee shall not be obligated to enter into any such supplemental
indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or
otherwise.

     (c) Any supplemental indenture authorized by the provisions of this Section may be executed
without the consent of the Holders of any of the Securities at the time outstanding,
notwithstanding any of the provisions of Section 8.2.

     Section 8.2 Supplemental Indentures With Consent of Securityholders. (a) With the
consent (evidenced as provided in Article VII) of the Holders of not less than a majority in
aggregate principal amount of the Securities at the time Outstanding of all series affected by such
supplemental indenture (voting as one class), the Issuer, when authorized by a resolution of its
Board of Directors (which resolution may provide general terms or parameters for such action and
may provide that the specific terms of such action may be determined in accordance with or pursuant
to an Issuer Order), and the Trustee may, from time to time and at any time, enter into an
indenture or indentures supplemental hereto, which comply with the Trust Indenture Act of 1939, as
then in effect, for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Indenture or of any supplemental indenture or of
modifying in any manner the rights of the Holders of the Securities of each such series or of the
Coupons appertaining to such Securities; provided, that no such
supplemental indenture shall (i)
extend the final maturity of any then issued Security, or reduce the principal amount thereof, or
reduce the rate or extend the time of payment of interest thereon, or reduce any amount payable on
redemption thereof, or make the principal thereof (including any amount in respect of original
issue discount), or interest thereon payable in any coin or currency other than that provided in
such Securities and any Coupons thereon or in accordance with the terms thereof, or reduce the
amount of the principal of a then issued Original Issue Discount Security that would be due and
payable upon an acceleration of the maturity thereof pursuant to Section 5.1 or the amount thereof
provable in bankruptcy pursuant to Section 5.2, or impair or affect the

36

 

right of any Securityholder to institute suit for the payment thereof or, if such Securities
provide therefor, any right of repayment at the option of the Securityholder, in each case without
the consent of the Holder of each Security so affected, or (ii) reduce the percentage in principal
amount of then issued Securities of any series, the consent of the Holders of which is required for
any such supplemental indenture, without the consent of the Holders of each Security so affected.

     (b) 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 Holders of Securities of such series, or of
Coupons appertaining to such Securities, with respect to such covenant or provision, shall be
deemed not to affect the rights under this Indenture of the Holders of Securities of any other
series or of the Coupons appertaining to such Securities.

     (c) Upon the request of the Issuer, accompanied by a copy of a resolution of the Board of
Directors (which resolution may provide general terms or parameters for such action and may provide
that the specific terms of such action may be determined in accordance with or pursuant to an
Issuer Order) certified by the secretary or an assistant secretary of the Issuer authorizing the
execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of
the consent of the Holders of the Securities as aforesaid and other documents, if any, required by
Section 7.1, the Trustee shall join with the Issuer in the execution of such supplemental indenture
unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under
this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be
obligated to, enter into such supplemental indenture.

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

     (e) Promptly after the execution by the Issuer and the Trustee of any supplemental indenture
pursuant to the provisions of this Article, the Issuer shall, or shall cause the Trustee to, give
notice thereof (i) if any Registered Securities of a series affected thereby are then Outstanding,
to the Holders thereof, by mailing a notice thereof by first-class mail to such Holders at their
addresses as they shall appear on the Security register, (ii) if any Unregistered Securities of a
series affected thereby are then Outstanding, to the Holders thereof who have filed their names and
addresses with the Trustee pursuant to Section 313(c)(2) of the Trust Indenture Act of 1939, by
mailing a notice thereof by first-class mail to such Holders at such addresses as were so furnished
to the Trustee and (iii) if any Unregistered Securities of a series affected thereby are then
Outstanding, to all Holders thereof, by publication of a notice thereof at least once in an
Authorized Newspaper in the Borough of Manhattan, The City of New York, and at least once in an
Authorized Newspaper in London (and, if required by Section 3.10, at least once in an Authorized
Newspaper in Luxembourg), and, in each case, such notice shall set forth in general terms the
substance of such supplemental indenture. Any failure of the Issuer or the Trustee to give such
notice, or any defect therein, shall not, however, in any way impair or affect the validity of any
such supplemental indenture.

     Section 8.3 Effect of Supplemental Indenture. Upon the execution of any supplemental
indenture pursuant to the provisions hereof, this Indenture shall be and be deemed to be modified
and amended in accordance therewith and the respective rights, limitations of rights, obligations,
duties and immunities under this Indenture of the Trustee, the Issuer and the Holders of Securities
of each series affected thereby shall thereafter be determined, exercised and enforced hereunder
subject in all respects to such modifications and amendments, and all the terms and conditions of
any such supplemental indenture shall be and be deemed to be part of the terms and conditions of
this Indenture for any and all purposes.

     Section 8.4 Documents to Be Given to Trustee. The Trustee, subject to the provisions
of Sections 6.1 and 6.2, shall be entitled to receive, and shall be fully protected in relying
upon, an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any
supplemental indenture executed pursuant to this Article 8 complies with the applicable
provisions of this Indenture.

37

 

     Section 8.5 Notation on Securities in Respect of Supplemental Indentures. Securities
of any series authenticated and delivered after the execution of any supplemental indenture
pursuant to the provisions of this Article may bear a notation in form approved by the Trustee for
such series as to any matter provided for by such supplemental indenture or as to any action taken
by Securityholders. If the Issuer or the Trustee shall so determine, new Securities of any series

modification of this Indenture contained in any such supplemental indenture may be prepared by the
Issuer, authenticated by the Trustee and delivered in exchange for the Securities of such series
then Outstanding.

     Section 8.6 Subordination Unimpaired. This Indenture may not be amended to alter the
subordination of any of the Outstanding Securities without the written consent of each holder of
Senior Indebtedness then outstanding that would be adversely affected thereby.

     Section 8.7 Conformity with Trust Indenture Act of 1939. Every supplemental indenture
executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act of
1939 as then in effect.

                    (2) all Securities of such series and, in the case of (X) or (Y) below, all
Coupons appertaining thereto not theretofore delivered to the Trustee for
cancellation (X) have become due and payable, or (Y) will become due and payable
within one year, or (Z) if redeemable at the option of the Issuer, are to be

has irrevocably deposited or caused to be deposited with the Trustee as trust
funds in trust for the purpose an amount in the currency or currencies or currency
unit or units in which the Securities of such series are payable, sufficient to
pay and discharge the entire indebtedness on such Securities and such Coupons not
theretofore delivered to the Trustee for cancellation, for principal, premium, if
any, and interest, with respect thereto, to the date of such deposit (in the case
of Securities which have become due and payable) or maturity date or redemption
date, as the case may be;

     (ii) the Issuer has paid or caused to be paid all other sums payable hereunder by the
Issuer; and

     (iii) the Issuer has delivered to the Trustee an Officers’ Certificate and an Opinion
of Counsel, each stating that all conditions precedent herein provided for relating to the
satisfaction and discharge of this Indenture as to such series have been complied with.

     (b) Notwithstanding the satisfaction and discharge of this Indenture, the obligation of the
Issuer to the Trustee under Section 6.6, the obligations of the Trustee to any Authenticating Agent
under Section 6.14 and, if money shall have been deposited with
the Trustee pursuant to (a)(i)(2)
of this Section, the obligations of the Trustee under Section 10.2 and the last paragraph of
Section 3.3 shall survive.

paragraph of Section 3.3, all money deposited with the Trustee pursuant to Section 10.1 shall be
held in trust and applied by it, in accordance with the provisions of the Securities, the Coupons

Issuer acting as its own paying agent) as the Trustee may determine, to the Persons entitled
thereto of the principal, premium, if any and any interest for whose payment such money has been
deposited with or received by the Trustee, but such money need not be segregated from other funds
except to the extent required by law.

     Section 10.3 Applicability of Defeasance Provisions; Issuer’s Option to Effect Defeasance
or Covenant Defeasance. If pursuant to Section 2.3 provision is made for either or both of (1)
defeasance of the Securities of or within a series under Section 10.4 or (2) covenant defeasance of
the Securities of or within a series under Section 10.5, then the provisions of such Section or
Sections, as the case may be, together with the provisions of Sections 10.6 through 10.9 inclusive,
with such modifications thereto as may be specified pursuant to Section 2.3 with respect to any
Securities, shall be applicable to such

39

 

Securities and any Coupons appertaining thereto, and the Issuer may at its option by or
pursuant to Board Resolution, at any time, with respect to such Securities and any Coupons
appertaining thereto, elect to have Section 10.4 (if applicable) or Section 10.5 (if applicable) be
applied to such Outstanding Securities and any Coupons appertaining thereto upon compliance with
the conditions set forth below in this Article.

     Section 10.4 Defeasance and Discharge. Upon the Issuer’s exercise of the option
specified in Section 10.3 applicable to this Section with respect to the Securities of or within a
series, the Issuer shall be deemed to have been discharged from its obligations with respect to
such Securities and any Coupons appertaining thereto on and after the date the conditions set forth
in Section 10.6 are satisfied (hereinafter “defeasance”). For this purpose, such defeasance means
that the Issuer shall be deemed to have paid and discharged the entire indebtedness represented by
such Securities and any Coupons appertaining thereto which shall thereafter be deemed to be
“Outstanding” only for the purposes of Section 10.7 and the other Sections of this Indenture
referred to in clause (2) of this Section, and to have satisfied all its other obligations under
such Securities and any Coupons appertaining thereto and this Indenture insofar as such Securities
and any Coupons appertaining thereto are concerned (and the Trustee, at the expense of the Issuer,
shall on an Issuer Order execute proper instruments acknowledging the same), except the following
which shall survive until otherwise terminated or discharged hereunder: (1) the rights of Holders
of such Securities and any Coupons appertaining thereto to receive, solely from the trust funds
described in Section 10.6(1) and as more fully set forth in such Section, payments in respect of
the principal of, premium, if any, and interest, if any, on such Securities or any Coupons
appertaining thereto when such payments are due; (2) the Issuer’s obligations with respect to such
Securities under Sections 2.8, 2.9, 3.2 and 3.3 and with respect to the payment of additional
amounts, if any, payable with respect to such Securities as specified pursuant to Section 2.3; (3)
the rights, powers, trusts, duties and immunities of the Trustee hereunder and (4) this Article 10.
Subject to compliance with this Article 10, the Issuer may exercise its option under this Section
notwithstanding the prior exercise of its option under Section 10.5 with respect to such Securities
and any Coupons appertaining thereto. Following a defeasance, payment of such Securities may not
be accelerated because of an Event of Default.

     Section 10.5 Covenant Defeasance. Upon the Issuer’s exercise of the option specified
in Section 10.3 applicable to this Section with respect to any Securities of or within a series,
the Issuer shall be released from its obligations under Sections 9.1 and 3.5 through 3.12 inclusive
and, if specified pursuant to Section 2.3, its obligations under any other covenant with respect to
such Securities and any Coupons appertaining thereto on and after the date the conditions set forth
in Section 10.6 are satisfied (hereinafter, “covenant defeasance”), and such Securities and any
Coupons appertaining thereto shall thereafter be deemed to be not “Outstanding” for the purposes of
any direction, waiver, consent or declaration or Act of Holders (and the consequences of any
thereof) in connection with Sections 9.1 and 3.5 through 3.12 inclusive or such other covenant, but
shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such
covenant defeasance means that, with respect to such Securities and any Coupons appertaining
thereto, the Issuer may omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such Section or such other covenant, whether directly or
indirectly, by reason of any reference elsewhere herein to any such Section or such other covenant
or by reason of reference in any such Section or such other covenant to any other provision herein
or in any other document and such omission to comply shall not constitute a default or an Event of
Default under Section 5.1(c) or (d) or otherwise, as the case may be, but, except as specified
above, the remainder of this Indenture and such Securities and any Coupons appertaining thereto
shall be unaffected thereby.

     Section 10.6 Conditions to Defeasance or Covenant Defeasance. The following shall be
the conditions to application of Section 10.4 or Section 10.5 to any Securities of or within a
series and any Coupons appertaining thereto:

     (a) The Issuer shall have deposited or caused to be deposited irrevocably with the Trustee (or
another Trustee satisfying the requirements of Section 6.9 who shall agree to comply with, and
shall be entitled to the benefits of, the provisions of Sections 10.3 through 10.9 inclusive and
the last paragraph of Section 3.3 applicable to the Trustee, for purposes of such Sections also a
“Trustee”) as trust funds in trust for the purpose of making the payments referred to in clauses
(X) and (Y) of this Section 10.6(a), specifically pledged as security for, and dedicated solely to,
the benefit of the Holders of such Securities

40

 

and any Coupons appertaining thereto, with instructions to the Trustee as to the application
thereof, (i) money in an amount (in such currency, currencies or currency unit or units in which
such Securities and any Coupons appertaining thereto are then specified as payable at maturity), or
(ii) if Securities of such series are not subject to repayment at the option of Holders, U.S.
Government Obligations which through the payment of interest and principal in respect thereof in
accordance with their terms will provide, not later than one day before the due date of any payment
referred to in clause (X) or (Y) of this
Section 10.6(a), money in an amount or (iii) a combination
thereof in an amount sufficient, in the opinion of a nationally recognized firm of independent
certified public accountants expressed in a written certification thereof delivered to the Trustee,
to pay and discharge, and which shall be applied by the Trustee to pay and discharge, (X) the
principal of, premium, if any, and interest, if any, on Securities and any Coupons appertaining
thereto on the maturity of such principal or installment of principal or interest and (Y) any
mandatory sinking fund payments applicable to such Securities on the day on which such payments are
due and payable in accordance with the terms of this Indenture and such Securities and any Coupons
appertaining thereto. Before such a deposit the Issuer may make arrangements satisfactory to the
Trustee for the redemption of Securities at a future date or dates in accordance with Article 12
which shall be given effect in applying the foregoing.

     (b) Such defeasance or covenant defeasance shall not result in a breach or violation of, or
constitute a default or Event of Default under, this Indenture or result in a breach or violation
of, or constitute a default under, any other material agreement or instrument to which the Issuer
is a party or by which it is bound.

     (c) In the case of an election under Section 10.4, the Issuer shall have delivered to the
Trustee an Officers’ Certificate and an Opinion of Counsel to
the effect that (i) the Issuer has
received from, or there has been published by, the Internal Revenue
Service a ruling, or (ii) since
the date of execution of this Indenture, there has been a change in the applicable Federal income
tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the
Holders of such Securities and any Coupons appertaining thereto will not recognize income, gain or
loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal
income tax on the same amount and in the same manner and at the same times, as would have been the
case if such deposit, defeasance and discharge had not occurred.

     (d) In the case of an election under Section 10.5, the Issuer shall have delivered to the
Trustee an Opinion of Counsel to the effect that the Holders of such Securities and any Coupons
appertaining thereto will not recognize income, gain or loss for Federal income tax purposes as a
result of such covenant defeasance and will be subject to Federal income tax on the same amounts,
in the same manner and at the same times as would have been the case if such covenant defeasance
had not occurred.

     (e) The Issuer shall have delivered to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that all conditions precedent to the defeasance under Section 10.4 or the
covenant defeasance under Section 10.5 (as the case may be), including those contained in this
Section 10.6 other than the 90 day period specified in
Section 10.6(g), have been complied with.

     (f) This Issuer shall have delivered to the Trustee an Officer’s Certificate to the effect
that neither such Securities nor any other Securities of the same series, if then listed on any
securities exchange, will be delisted as a result of such deposit.

     (g) No event which is, or after notice or lapse of time or both would become, an Event of
Default with respect to such Securities or any other Securities shall have occurred and be
continuing at the time of such deposit or, with regard to any such event specified in Sections
5.1(e) and (f), at any time on or prior to the 90th day after the date of such deposit (it being
understood that this condition shall not be deemed satisfied until after such 90th day).

     (h) Such defeasance or covenant defeasance shall not result in the trust arising from such
deposit constituting an investment company within the meaning of the Investment Company Act of 1940
unless such trust shall be registered under such Act or exempt from registration thereunder.

41

 

     (i) Such defeasance or covenant defeasance shall be effected in compliance with any additional
or substitute terms, conditions or limitations which may be imposed on the Issuer in connection
therewith as contemplated by Section 2.3.

     Section 10.7 Deposited Money and U.S. Government Obligations to be Held in Trust.
Subject to the provisions of the last paragraph of Section 3.3, all money and U.S. Government
Obligations (or other property as may be provided pursuant to Section 2.3) (including the proceeds
thereof) deposited with the Trustee pursuant to Section 10.6 in respect of any Securities of any
series and any Coupons appertaining thereto shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities and any Coupons appertaining thereto and this
Indenture, to the payment, either directly or through any paying agent (including the Issuer acting
as its own paying agent) as the Trustee may determine, to the Holders of such Securities and any
Coupons appertaining thereto of all sums due and to become due thereon in respect of principal,
premium, if any, and interest, if any, but such money need not be segregated from other funds
except to the extent required by law.

     Section 10.8 Repayment to Issuer. The Trustee (any paying agent) shall promptly pay
to the Issuer upon Issuer Order any excess money or securities held by them at any time.

     Section 10.9 Indemnity For U.S. Government Obligations. The Issuer shall pay, and
shall indemnify the Trustee against, any tax, fee or other charge imposed on or assessed against
U.S. Government Obligations deposited pursuant to this Article or the principal and interest and
any other amount received on such U.S. Government Obligations.

     Section 10.10 Reimbursement. If the Trustee or the paying agent is unable to apply
any money in accordance with this Article with respect to any Securities by reason of any order or
judgment of any court or government authority enjoining, restraining or otherwise prohibiting such
application, then the obligations under this Indenture and such Securities from which the Issuer
has been discharged or released pursuant to Section 10.4 or 10.5 shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such Securities, until such
time as the Trustee or paying agent is permitted to apply all money held in trust pursuant to
Section 10.7 with respect to such Securities in accordance with this Article; provided, however,
that if the Issuer makes any payment of principal of or any premium or interest on any such
Security following such reinstatement of its obligations, the Issuer 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.

ARTICLE 11

MISCELLANEOUS PROVISIONS

     Section 11.1 Incorporators, Stockholders, Officers and Directors of Issuer Exempt from
Individual Liability. No recourse under or upon any obligation, covenant or agreement
contained in this Indenture, or in any Security, or because of any indebtedness evidenced thereby,
shall be had against any incorporator, as such or against any past, present or future stockholder,
officer or director, as such, of the Issuer or of any successor, either directly or through the
Issuer or any successor, under any rule of law, statute or constitutional provision or by the
enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such
liability being expressly waived and released by the acceptance of the Securities and the Coupons
appertaining thereto by the Holders thereof and as part of the consideration for the issue of the
Securities and the Coupons appertaining thereto.

     Section 11.2 Provisions of Indenture for the Sole Benefit of Parties and Holders of
Securities and Coupons. Nothing in this Indenture, in the Securities or in the Coupons
appertaining thereto, expressed or implied, shall give or be construed to give to any person, firm
or corporation, other than the parties hereto and their successors and the holders of Senior
Indebtedness and the Holders of the Securities or Coupons, if any, any legal or equitable right,
remedy or claim under this Indenture or under any covenant or provision herein contained, all such
covenants and provisions being for the sole benefit of the parties

42

 

hereto and their successors, the holders of the Senior Indebtedness and of the Holders of the
Securities or Coupons, if any.

     Section 11.3 Successors and Assigns of Issuer Bound by Indenture. All the covenants,
stipulations, promises and agreements in this Indenture contained by or in behalf of the Issuer
shall bind its successors and assigns, whether so expressed or not.

     Section 11.4 Notices and Demands on Issuer, Trustee and Holders of Securities and
Coupons. Any notice or demand which by any provision of this Indenture is required or
permitted to be given or served by the Trustee or by the Holders of Securities or Coupons to or on
the Issuer shall be in writing (which may be by facsimile) and may be given or served by being
deposited postage prepaid, first-class mail (except as otherwise specifically provided herein)
addressed (until another address of the Issuer is filed by the Issuer with the Trustee) to
AMERIGROUP Corporation, 4425 Corporation Lane, Virginia Beach, Virginia 23462, Attention: General
Counsel. Any notice, direction, request or demand by the Issuer or any Holder of Securities or
Coupons to or upon the Trustee shall be sufficient for every purpose hereunder if made, given,
furnished or filed in writing (which may be by facsimile) to or with the Trustee at its Corporate

shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed,
first-class postage prepaid, to each Holder entitled thereto, at his or her last address as it
appears in the Security register. In any case where notice to such Holders is given by mail,
neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular
Holder shall affect the sufficiency of such notice with respect to other Holders. Where this
Indenture provides for notice in any manner, such notice may be waived in writing by the person
entitled to receive such notice, either before or after the event, and such waiver shall be the
equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in reliance upon such
waiver.

     In case, by reason of the suspension of or irregularities in regular mail service, it shall be
impracticable to mail notice to the Issuer when such notice is required to be given pursuant to any
provision of this Indenture, then any manner of giving such notice as shall be reasonably
satisfactory to the Trustee shall be deemed to be a sufficient giving of such notice.

     Section 11.5 Officer’s Certificates and Opinions of Counsel; Statements to Be Contained
Therein. Upon any application, request or demand by the Issuer to the Trustee to take any
action under any of the provisions of this Indenture, the Issuer shall furnish to the Trustee an
Officer’s Certificate stating that all conditions precedent provided for in this Indenture relating
to the proposed action have been complied with and an Opinion of Counsel stating that in the
opinion of such counsel all such conditions precedent have been complied with, except that in the
case of any such application, request or demand as to which the furnishing of such documents is
specifically required by any provision of this Indenture relating to such particular application,
request or demand, no additional certificate or opinion need be furnished. 

     Each certificate or opinion provided for in this Indenture and delivered to the Trustee with
respect to compliance with a condition or covenant provided for in this Indenture shall include (1)
a statement that the person making such certificate or opinion has read such covenant or condition,
(2) a brief statement as to the nature and scope of the examination or investigation upon which the
statements or opinions contained in such certificate or opinion are based, (3) a statement that, in

has been complied with and (4) a statement as to whether or not, in the opinion of such person,
such condition or covenant has been complied with.

     Any certificate, statement or opinion of an officer of the Issuer may be based, insofar as it
relates to legal matters, upon a certificate or opinion of or representations by counsel, unless
such officer knows that the certificate or opinion or representations with respect to the matters
upon which his or her

43

 

certificate, statement or opinion may be based as aforesaid are erroneous, or in the exercise
of reasonable care should know that the same are erroneous. Any certificate, statement or opinion
of counsel may be based, insofar as it relates to factual matters, information with respect to
which is in the possession of the Issuer, upon the certificate, statement or opinion of or
representations by an officer or officers of the Issuer, unless such counsel actually knows that
the certificate, statement or opinion or representations with respect to the matters upon which his
or her certificate, statement or opinion may be based as aforesaid are erroneous, or in the
exercise of reasonable care should know that the same are erroneous.

     Any certificate, statement or opinion of an officer of the Issuer or of counsel may be based,
insofar as it relates to accounting matters, upon a certificate or opinion of or representations by
an accountant or firm of accountants in the employ of the Issuer, unless such officer or counsel,
as the case may be, knows that the certificate or opinion or representations with respect to the
accounting matters upon which his or her certificate, statement or opinion may be based as
aforesaid are erroneous, or in the exercise of reasonable care should know that the same are
erroneous.

of interest on or principal of the Securities of any series or any Coupons appertaining thereto or
the date fixed for redemption or repayment of any such Security or Coupon shall not be a Business
Day, then payment of interest or principal need not be made on such date, but may be made on the
next succeeding Business Day with the same force and effect as if made on the date of maturity or
the date fixed for redemption, and no interest shall accrue for the period after such date.

     Section 11.7 Conflict of Any Provision of Indenture with Trust Indenture Act of 1939.
If and to the extent that any provision of this Indenture limits, qualifies or conflicts with the
duties imposed by, or with another provision (an “incorporated provision”) included in this
Indenture by operation of, Sections 310 to 318, inclusive, of the Trust Indenture Act of 1939, such
imposed duties or incorporated provision shall control.

     Section 11.8 New York Law to Govern; Waiver of Jury Trial. This Indenture and each
Security and Coupon shall be deemed to be a contract under the laws of the State of New York, and
for all purposes shall be construed in accordance with the laws of such State.

     EACH OF THE ISSUER, THE TRUSTEE AND THE HOLDERS BY THEIR ACCEPTANCE OF ANY SECURITY HEREBY
IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL
BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE
TRANSACTION CONTEMPLATED HEREBY.

     Section 11.9 Counterparts. This Indenture may be executed in any number of
counterparts, each of which shall be an original; but such counterparts shall together constitute
but one and the same instrument.

     Section 11.10 Effect of Headings. The Article and Section headings herein and the
Table of Contents are for convenience only and shall not affect the construction hereof.

     Section 11.11 Securities in a Foreign Currency or in ECU. Unless otherwise specified
in an Officer’s Certificate delivered pursuant to Section 2.3 of this Indenture with respect to a
particular series of Securities, whenever for purposes of this Indenture any action may be taken by
the Holders of a specified percentage in aggregate principal amount of Securities of all series or
all series affected by a particular action at the time Outstanding and, at such time, there are
Outstanding Securities of any series which are denominated in a coin or currency other than Dollars
(including ECUs), then the principal amount of Securities of such series which shall be deemed to
be Outstanding for the purpose of taking such action

44

 

shall be that amount of Dollars that could be obtained for such amount at the Market Exchange
Rate. For purposes of this Section 11.11, Market Exchange Rate shall mean the noon Dollar buying
rate in New York City for cable transfers of that currency as published by the Federal Reserve Bank
of New York; provided, however, in the case of ECUs, Market Exchange Rate shall mean the rate of
exchange determined by the Commission of the European Communities (or any successor thereto) as
published in the Official Journal of the European Communities (such publication or any successor
publication, the “Journal”). If such Market Exchange Rate is not available for any reason with
respect to such currency, the Trustee shall use, in its sole discretion and without liability on
its part, such quotation of the Federal Reserve Bank of New York or, in the case of ECUs, the rate
of exchange as published in the Journal, as of the most recent available date, or quotations or, in
the case of ECUs, rates of exchange from one or more major banks in The City of New York or in the
country of issue of the currency in question, which for purposes of the ECU shall be Brussels,
Belgium, or such other quotations or, in the case of ECU, rates of exchange as the Trustee shall
deem appropriate. The provisions of this paragraph shall apply in determining the equivalent
principal amount in respect of Securities of a series denominated in a currency other than Dollars
in connection with any action taken by Holders of Securities pursuant to the terms of this
Indenture.

     All decisions and determinations of the Trustee regarding the Market Exchange Rate or any
alternative determination provided for in the preceding paragraph shall be in its sole discretion
and shall, in the absence of manifest error, be conclusive to the extent permitted by law for all
purposes and irrevocably binding upon the Issuer and all Holders.

     Section 11.12 Judgment Currency. The Issuer agrees, to the fullest extent that it may
effectively do so under applicable law, that (1) if for the purpose of obtaining judgment in any
court it is necessary to convert the sum due in respect of the principal of or interest on the
Securities of any series (the “Required Currency”) into a currency in which a judgment will be
rendered (the “Judgment Currency”), the rate of exchange used shall be the rate at which in
accordance with normal banking procedures the Trustee could purchase in The City of New York the
Required Currency with the Judgment Currency on the day on which final unappealable judgment is
entered, unless such day is not a Business Day, then, to the extent permitted by applicable law,
the rate of exchange used shall be the rate at which in accordance with normal banking procedures
the Trustee could purchase in The City of New York the Required Currency with the Judgment Currency
on the Business Day preceding the day on which final unappealable judgment is entered and (2) its
obligations under this Indenture to make payments in the Required Currency (a) shall not be
discharged or satisfied by any tender, or any recovery pursuant to any judgment (whether or not
entered in accordance with subsection (1)), in any currency other than the Required Currency,
except to the extent that such tender or recovery shall result in the actual receipt, by the payee,
of the full amount of the Required Currency expressed to be payable in respect of such payments,
(b) shall be enforceable as an alternative or additional cause of action for the purpose of
recovering in the Required Currency the amount, if any, by which such actual receipt shall fall
short of the full amount of the Required Currency so expressed to be payable and (c) shall not be
affected by judgment being obtained for any other sum due under this Indenture.

     Section 11.13 Separability Clause. If any provision of this Indenture or of the
Securities, or the application of any such provision to any Person or circumstance, shall be held
to be invalid, illegal or unenforceable, the remainder of this Indenture or of the Securities, or
the application of such provision to Persons or circumstances other than those as to whom or which
it is invalid, illegal or unenforceable, shall not in any way be affected or impaired thereby.

ARTICLE 12

REDEMPTION OF SECURITIES AND SINKING FUNDS

     Section 12.1 Applicability of Article. The provisions of this Article shall be
applicable to the Securities of any series which are redeemable before their maturity or to any
sinking fund for the retirement of Securities of a series except as otherwise specified as
contemplated by Section 2.3 for Securities of such series.

45

 

     Section 12.2 Notice of Redemption; Partial Redemptions. Notice of redemption to the
Holders of Registered Securities of any series to be redeemed as a whole or in part at the option
of the Issuer shall be given by mailing notice of such redemption by first class mail, postage
prepaid, at least 30 days and not more than 60 days prior to the date fixed for redemption to such
Holders of Securities of such series at their last addresses as they shall appear upon the registry
books. Notice of redemption to the Holders of Unregistered Securities to be redeemed as a whole or
in part, who have filed their names and addresses with the Trustee pursuant to Section 313(c)(2) of
the Trust Indenture Act of 1939 shall be given at the Issuer’s expense by mailing notice of such
redemption, by first class mail, postage prepaid, at least 30 days and not more than 60 prior to
the date fixed for redemption, to such Holders at such addresses as were so furnished to the
Trustee (and, in the case of any such notice given by the Issuer, the Trustee shall make such
information available to the Issuer for such purpose). Notice of redemption to all other Holders
of Unregistered Securities shall be published in an Authorized Newspaper in the Borough of
Manhattan, The City of New York, and in an Authorized Newspaper in London (and, if required by
Section 3.10, in an Authorized Newspaper in Luxembourg), in each case, once in each of three
successive calendar weeks, the first publication to be not less than 30 nor more than 60 days prior
to the date fixed for redemption. Any notice which is mailed in the manner herein provided shall
be conclusively presumed to have been duly given, whether or not the Holder receives the notice.
Failure to give notice by mail, or any defect in the notice to the Holder of any Security of a
series designated for redemption as a whole or in part shall not affect the validity of the
proceedings for the redemption of any other Security of such series.

     The notice of redemption to each such Holder shall identify the securities to be redeemed
(including CUSIP numbers), shall specify, the principal amount of each Security of such series held
by such Holder to be redeemed, the date fixed for redemption, the redemption price, the place or
places of payment, that payment will be made upon presentation and surrender of such Securities
and, in the case of Securities with Coupons attached thereto, of all Coupons appertaining thereto
maturing after the date fixed for redemption, that such redemption is pursuant to the mandatory or
optional sinking fund, or both, if such be the case, that interest accrued to the date fixed for
redemption will be paid as specified in such notice and that on and after said date interest
thereon or on the portions thereof to be redeemed will cease to accrue. In case any Security of a
series is to be redeemed in part only the notice of redemption shall state the portion of the
principal amount thereof to be redeemed and shall state that on and after the date fixed for
redemption, upon surrender of such Security, a new Security or Securities of such series in
principal amount equal to the unredeemed portion thereof will be issued.

     The notice of redemption of Securities of any series to be redeemed at the option of the
Issuer shall be given by the Issuer or, at the Issuer’s request, by the Trustee in the name and at
the expense of the Issuer.

     On or before 10:00 a.m., New York City time, the redemption date specified in the notice of
redemption given as provided in this Section, the Issuer will deposit with the Trustee or with one
or more paying agents (or, if the Issuer is acting as its own paying agent, set aside, segregate
and hold in trust as provided in Section 3.3) an amount of money sufficient to redeem on the
redemption date all the Securities of such series so called for redemption at the appropriate
redemption price, together with accrued interest to the date fixed for redemption. The Issuer will
deliver to the Trustee at least 75 days prior to the date fixed for redemption (unless a shorter
period shall be acceptable to the Trustee) an Officer’s Certificate stating the aggregate principal
amount of Securities to be redeemed. In case of a redemption at the election of the Issuer prior
to the expiration of any restriction on such redemption, the Issuer shall deliver to the Trustee,
prior to the giving of any notice of redemption to Holders pursuant to this Section, an Officer’s
Certificate stating that such restriction has been complied with.

     If less than all the Securities of a series are to be redeemed, the Trustee shall select, in
such manner as it shall deem appropriate and fair, which may include by lot, Securities of such
Series to be redeemed in whole or in part. Securities may be redeemed in part in multiples equal
to the minimum authorized denomination for Securities of such series or any multiple thereof. The
Trustee shall promptly notify the Issuer in writing of the Securities of such series selected for
redemption and, in the case of any Securities of such series selected for partial redemption, the
principal amount thereof to be redeemed. For all purposes of this Indenture, unless the context
otherwise requires, all provisions relating to the

46

 

redemption of Securities of any series shall relate, in the case of any Security redeemed or
to be redeemed only in part, to the portion of the principal amount of such Security which has been
or is to be redeemed.

     Section 12.3 Payment of Securities Called for Redemption. If notice of redemption has
been given as above provided, the Securities or portions of Securities specified in such notice
shall become due and payable on the date and at the place stated in such notice at the applicable
redemption price, together with interest accrued to the date fixed for redemption, and on and after
said date (unless the Issuer shall default in the payment of such Securities at the redemption
price, together with interest accrued to said date) interest on the Securities or portions of
Securities so called for redemption shall cease to accrue, and the unmatured Coupons, if any,
appertaining thereto shall be void, and, except as provided in Sections 3.3 and 6.5, such
Securities shall cease from and after the date fixed for redemption to be entitled to any benefit
or security under this Indenture, and the Holders thereof shall have no right in respect of such
Securities except the right to receive the redemption price thereof and unpaid interest to the date
fixed for redemption. On presentation and surrender of such Securities at a place of payment
specified in said notice, together with all Coupons, if any, appertaining thereto maturing after
the date fixed for redemption, said Securities or the specified portions thereof shall be paid and
redeemed by the Issuer at the applicable redemption price, together with interest accrued thereon
to the date fixed for redemption; provided that payment of interest becoming due on or prior to the
date fixed for redemption shall be payable in the case of Securities with Coupons attached thereto,
to the Holders of the Coupons for such interest upon surrender thereof, and in the case of
Registered Securities, to the Holders of such Registered Securities registered as such on the
relevant record date subject to the terms and provisions of Sections 2.3 and 2.7 hereof.

     If any Security called for redemption shall not be so paid upon surrender thereof for
redemption, the principal shall, until paid or duly provided for, bear interest from the date fixed
for redemption at the rate of interest or Yield to Maturity (in the case of an Original Issue
Discount Security) borne by such Security.

     If any Security with Coupons attached thereto is surrendered for redemption and is not
accompanied by all appurtenant Coupons maturing after the date fixed for redemption such Security
may be redeemed after deducting from the redemption price any amount equal to the face amount of
all such missing Coupons, or the surrender of such missing Coupon or Coupons may be waived by the
Issuer and the Trustee if there be furnished to them such security or indemnity as they may require
to save each of them and any paying agent harmless. If thereafter the Holder of such Security
shall surrender to the Trustee or any paying agent any such missing Coupon in respect of which a
deduction shall have been made from the redemption price, such Holder shall be entitled to receive
the amount so deducted; provided, however, that interest represented by Coupons shall be payable as
provided in Section 2.9 and, unless otherwise specified as contemplated by Section 2.3, only upon
presentation and surrender of those Coupons.

     Upon presentation of any Security redeemed in part only, the Issuer shall execute and the
Trustee shall authenticate and deliver to or on the order of the Holder thereof, at the expense of
the Issuer, a new Security or Securities of such series, of authorized denominations, in principal
amount equal to the unredeemed portion of the Security so presented.

     Section 12.4 Exclusion of Certain Securities from Eligibility for Selection for
Redemption. Securities shall be excluded from eligibility for selection for redemption if they
are identified by registration and certificate number in an Officer’s Certificate delivered to the
Trustee at least 40 days prior to the last date on which notice of redemption may be given as being
owned of record and beneficially by, and not pledged or hypothecated by either (a) the Issuer or
(b) an entity specifically identified in such written statement as directly or indirectly
controlling or controlled by or under direct or indirect common control with the Issuer.

     Section 12.5 Mandatory and Optional Sinking Funds. The minimum amount of any sinking
fund payment provided for by the terms of the Securities of any series is herein referred to as a
“mandatory sinking fund payment”, and any payment in excess of such minimum amount provided for by
the terms of the Securities of any series is herein referred to as an “optional sinking fund payment”. The
date on which a sinking fund payment is to be made is herein referred to as the “sinking fund
payment date”.

47

 

     (a) In lieu of making all or any part of any mandatory sinking fund payment with respect to
any series of Securities in cash, the Issuer may at its option (i) deliver to the Trustee
Securities of such series theretofore purchased or otherwise acquired (except upon redemption
pursuant to the mandatory sinking fund) by the Issuer or receive credit for Securities of such
series (not previously so credited) theretofore purchased or otherwise acquired (except as
aforesaid) by the Issuer and delivered to the Trustee for cancellation pursuant to Section 2.10,
(ii) receive credit for optional sinking fund payments (not previously so credited) made pursuant to
this Section, or (iii) receive credit for Securities of such series (not previously so credited)
redeemed by the Issuer through any optional redemption provision contained in the terms of such
series. Securities so delivered or credited shall be received or credited by the Trustee at the
sinking fund redemption price specified in such Securities.

     (b) On or before the 60th day next preceding each sinking fund payment date for any series,
the Issuer will deliver to the Trustee an Officer’s Certificate (which need not contain the
statements required by Section 11.5) (i) specifying the portion of the mandatory sinking fund
payment to be satisfied by payment of cash and the portion to be satisfied by credit of Securities
of such series and the basis for such credit, (ii) stating that none of the Securities of such
series has theretofore been so credited, (iii) stating that no defaults in the payment of interest or
Events of Default with respect to such series have occurred (which have not been waived or cured)
and are continuing and (iv) stating whether or not the Issuer intends to exercise its right to make
an optional sinking fund payment with respect to such series and, if so, specifying the amount of
such optional sinking fund payment which the Issuer intends to pay on or before the next succeeding
sinking fund payment date. Any Securities of such series to be credited and required to be
delivered to the Trustee in order for the Issuer to be entitled to credit therefor as aforesaid
which have not theretofore been delivered to the Trustee shall be delivered for cancellation
pursuant to Section 2.10 to the Trustee with such Officer’s Certificate (or reasonably promptly
thereafter if acceptable to the Trustee). Such Officer’s Certificate shall be irrevocable and upon
its receipt by the Trustee the Issuer shall become unconditionally obligated to make all the cash
payments or payments therein referred to, if any, on or before the next succeeding sinking fund
payment date. Failure of the Issuer, on or before any such 60th day, to deliver such Officer’s
Certificate and Securities specified in this paragraph, if any, shall not constitute a default but
shall constitute, on and as of such date, the irrevocable election of
the Issuer (1) that the
mandatory sinking fund payment for such series due on the next succeeding sinking fund payment date
shall be paid entirely in cash without the option to deliver or credit Securities of such series in
respect thereof and (2) that the Issuer will make no optional sinking fund payment with respect to
such series as provided in this Section.

     (c) If the sinking fund payment or payments (mandatory or optional or both) to be made in cash
on the next succeeding sinking fund payment date plus any unused balance of any preceding sinking
fund payments made in cash shall exceed $50,000 (or the equivalent thereof in any Foreign Currency
or ECU) or a lesser sum in Dollars (or the equivalent thereof in any Foreign Currency or ECU) if
the Issuer shall so request with respect to the Securities of any particular series, such cash
shall be applied on the next succeeding sinking fund payment date to the redemption of Securities
of such series at the sinking fund redemption price together with accrued interest to the date
fixed for redemption. If such amount shall be $50,000 (or the equivalent thereof in any Foreign
Currency or ECU) or less and the Issuer makes no such request then it shall be carried over until a
sum in excess of $50,000 (or the equivalent thereof in any Foreign Currency or ECU) is available.
The Trustee shall select, in the manner provided in Section 12.2, for redemption on such sinking
fund payment date a sufficient principal amount of Securities of such series to absorb said cash,
as nearly as may be, and shall (if requested in writing by the Issuer) inform the Issuer of the
serial numbers of the Securities of such series (or portions thereof) so selected. Securities
shall be excluded from eligibility for redemption under this Section if they are identified by
registration and certificate number in an Officer’s Certificate delivered to the Trustee at least
60 days prior to the sinking fund payment date as being owned of record and beneficially by, and
not pledged or hypothecated by either (i) the Issuer or (ii) an entity specifically identified in
such Officer’s Certificate as directly or indirectly controlling or controlled by or under direct
or indirect common control with the Issuer. The Trustee, in the name and at the expense of the
Issuer (or the Issuer, if it shall so request the Trustee in writing) shall cause
notice of redemption of the Securities of such series to be given in substantially the manner
provided in Section 12.2 (and with the effect provided in Section 12.3) for the redemption of
Securities of such series in part at the option of the Issuer. The amount of any sinking fund
payments not so applied or allocated to the

48

 

redemption of Securities of such series shall be added
to the next cash sinking fund payment for such series and, together with such payment, shall be
applied in accordance with the provisions of this Section. Any and all sinking fund monies held on
the stated maturity date of the Securities of any particular series (or earlier, if such maturity
is accelerated), which are not held for the payment or redemption of particular Securities of such
series shall be applied, together with other monies, if necessary, sufficient for the purpose, to
the payment of the principal of, and interest on, the Securities of such series at maturity.

     (d) On or before each sinking fund payment date, the Issuer shall pay to the Trustee in cash
or shall otherwise provide for the payment of all interest accrued to the date fixed for redemption
on Securities to be redeemed on the next following sinking fund payment date.

     (e) The Trustee shall not redeem or cause to be redeemed any Securities of a series with
sinking fund monies or give any notice of redemption of Securities for such series by operation of
the sinking fund during the continuance of a default in payment of interest on such Securities or
of any Event of Default except that, where the giving of notice of redemption of any Securities
shall theretofore have been made, the Trustee shall redeem or cause to be redeemed such Securities,
provided that it shall have received from the Issuer a sum sufficient for such redemption. Except
as aforesaid, any monies in the sinking fund for such series at the time when any such default or
Event of Default shall occur, and any monies thereafter paid into the sinking fund, shall, during
the continuance of such default or Event of Default, be deemed to have been collected under Article
5 and held for the payment of all such Securities. In case such Event of Default shall have been
waived as provided in Section 5.10 or the default cured on or before the sixtieth day preceding the
sinking fund payment date in any year, such monies shall thereafter be applied on the next
succeeding sinking fund payment date in accordance with this Section to the redemption of such
Securities.

ARTICLE 13

SUBORDINATION

     Section 13.1 Agreement to Subordinate. The Issuer, for itself, its successors and
assigns, covenants and agrees, and each Holder of a Security or Coupon, by its acceptance thereof,
likewise covenants and agrees, that the payment of the principal of and interest on each and all of
the Securities and any Coupons is hereby expressly subordinated, to the extent and in the manner
hereinafter in this Article 13 set forth, in right of payment to the prior payment in full of all
Senior Indebtedness.

     Section 13.2 Rights of Senior Indebtedness in the Event of Insolvency, Etc., of the
Issuer.

     (a) In the event of any insolvency or bankruptcy proceedings, and any receivership,
liquidation, reorganization or other similar proceedings in connection therewith, relative to the
Issuer or to its creditors, as such, or to its property, and in the event of any proceedings for
voluntary liquidation, dissolution or other winding up of the Issuer, whether or not involving
insolvency or bankruptcy, and in the event of any execution sale, then the holders of Senior
Indebtedness shall be entitled to receive payment in full of principal thereof and interest due
thereon (including, without limitation, except to the extent, if any, prohibited by mandatory
provisions of law, post-petition interest in any such proceedings) in money or money’s worth of all
Senior Indebtedness before the Holders are entitled to receive any payment on account of the
principal of or interest on the indebtedness evidenced by the Securities or of the Coupons, and to
that end the holders of Senior Indebtedness shall be entitled to receive for application in payment
thereof any payment or distribution of any kind or character, whether in cash or property or
securities, which may be payable or deliverable in connection with any such proceedings or sale in
respect of the principal of or interest on the Securities or Coupons other than securities of the
Issuer as reorganized or readjusted or securities of the Issuer or any other corporation provided
for by a plan of reorganization or readjustment the payment of which is subordinate, at least to
the extent provided in this Article 13 with respect to the Securities or Coupons, to the payment of
all indebtedness of the nature of Senior Indebtedness, provided
that the rights of the holders of the Senior Indebtedness are not altered by such
reorganization or readjustment;

49

 

     (b) In the event and during the continuation of any default in payment of any Senior
Indebtedness or if any event of default, as therein defined, shall exist under any Senior
Indebtedness or any agreement pursuant to which any Senior Indebtedness is issued, no payment of
the principle of or interest on the Securities or Coupons shall be made and the Issuer covenants
that it will, upon ascertaining any such default or event of default, provide written notice to a
Responsible Officer of the Trustee of such default or event of default;

     (c) In the event that the Securities of any series are declared due and payable before their
expressed maturity because of the occurrence of an Event of Default (under circumstances when the
provisions of Subsection (a) of this Section 13.2 shall not be applicable), the holders of all
Senior Indebtedness shall be entitled to receive payment in full in money or money’s worth of such
Senior Indebtedness before such Holders are entitled to receive any payment on account of the
principal of or interest on the Securities or Coupons; and

     (d) No holder of Senior Indebtedness shall be prejudiced in his or her right to enforce
subordination of the Securities or Coupons by any act or failure to act on the part of the Issuer.

     Section 13.3 Payment Over of Proceeds Received on Securities. In the event that,
notwithstanding the provisions of Section 13.2, any payment or distribution of assets of the Issuer
of any kind or character, whether in cash, property or securities (other than securities of the
Issuer as reorganized or readjusted or securities of the Issuer or any other corporation provided
for by a plan of reorganization or readjustment the payment of which is subordinate, at least to
the extent provided in this Article 13 with respect to the Securities or Coupons, to the payment of
all indebtedness of the nature of Senior Indebtedness, provided that the rights of the holders of
the Senior Indebtedness are not altered by such reorganization or readjustment) shall be received
by the Holders or by the Trustee for their benefit in connection with any proceedings or sale
referred to in Subsection (a) of Section 13.2 before all Senior Indebtedness is paid in full in
money or money’s worth, such payment or distribution shall be paid over to the holders of such
Senior Indebtedness or their representative or representatives or to the trustee or trustees under
any indenture under which any instruments evidencing any of such Senior Indebtedness may have been
issued, ratably according to the aggregate amounts remaining unpaid on account of the Senior
Indebtedness held or represented by each, for application to the payment of all Senior Indebtedness
remaining unpaid until all such Senior Indebtedness shall have been paid in full in money or
money’s worth, after giving effect to any concurrent payment or distribution to the holders of such
Senior Indebtedness. 

     From and after the payment in full in money or money’s worth of all Senior Indebtedness, the
Holders (together with the holders of any other indebtedness of the Issuer which is subordinate in
right of payment to the payment in full of all Senior Indebtedness, which is not subordinate in
right of payment to the Securities or Coupons and which by its terms grants such right of
subrogation to the holder thereof) shall be subrogated to the rights of the holders of Senior
Indebtedness to receive payments or distributions of assets or securities of the Issuer applicable
to the Senior Indebtedness until the Securities and any Coupons shall be paid in full, and, for the
purposes of such subrogation, no such payments or distributions to the holders of Senior
Indebtedness of assets or securities, which otherwise would have been payable or distributable to
Holders, shall, as between the Issuer, its creditors other than the holders of Senior Indebtedness,
and the Holders, be deemed to be a payment by the Issuer to or on account of the Senior
Indebtedness, it being understood that the provisions of this Article 13 are and are intended
solely for the purpose of defining the relative rights of the Holders, on the one hand, and the
holders of the Senior Indebtedness, on the other hand, and nothing contained in this Article 13 or
elsewhere in this Indenture or in the Securities or Coupons is intended to or shall impair as
between the Issuer, its creditors other than the holders of Senior Indebtedness, and the Holders,
the obligation of the Issuer, which is unconditional and absolute, to pay to the Holders the
principal of and interest on the Securities or Coupons as and when the same shall become due and
payable in accordance with their terms, or to affect the relative rights of the Holders and
creditors of the Issuer other than the holders of the Senior Indebtedness, nor shall anything
herein or therein prevent the Trustee or the holder of any Security or Coupon from exercising all
remedies
otherwise permitted by applicable law upon default under this Indenture subject to the rights
of the holders of Senior Indebtedness, under Section 13.2, to receive cash, property or securities
of the Issuer otherwise payable or deliverable to the holders of the Securities or Coupons.

50

 

     Upon any distribution or payment in connection with any proceedings or sale referred to in
Subsection (a) of Section 13.2, the Trustee, subject as between the Trustee and the Holders to the
provisions of Sections 6.1 and 6.2 hereof, shall be entitled to rely upon a certificate of the
liquidating trustee or agent or other Person making any distribution or payment to the Trustee for
the purpose of ascertaining the holders of Senior Indebtedness entitled to participate in such
payment or distribution, the amount of such Senior Indebtedness or the amount payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this
Article 13. In the event that the Trustee determines, in good faith, that further evidence is
required with respect to the right of any Person as a holder of Senior Indebtedness to participate
in any payment or distribution pursuant to this Section 13.3, the Trustee may request such Person
to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior
Indebtedness held by such Person, as to the extent to which such Person is entitled to participate
in such payment or distribution, and as to other facts pertinent to the rights of such Person under
this Section 13.3, and if such evidence is not furnished, the Trustee may defer any payment to such
Person pending judicial determination as to the right of such Person to receive such payment.

     The Trustee, however, shall not be deemed to owe any fiduciary duty to the holders of Senior
Indebtedness, and shall not be liable to any such holders if it shall mistakenly pay over or
distribute to Holders or the Issuer or any other Person monies or assets to which any holders of
Senior Indebtedness shall be entitled by virtue of Article 13 of this Indenture or otherwise. With
respect to the holders of Senior Indebtedness, the Trustee undertakes to perform or to observe only
such of its covenants or obligations as are specifically set forth in this Article and no implied
covenants or obligations with respect to holders of Senior Indebtedness shall be read into this
Indenture against the Trustee.

     Section 13.4 Payments to Holders. Nothing contained in this Article 13 or elsewhere
in this Indenture, or in any of the Securities or in any Coupon, shall prevent at any time, (1) the
Issuer from making payments at any time of principal of or interest on the Securities or Coupons,
except under the conditions described in Section 13.2 or during the pendency of any proceedings or
sale therein referred to, provided, however, that payments of principal of or interest on the
Securities or Coupons shall only be made by the Issuer within three business days of the due dates
for such payments or (2) the receipt or the application by the Trustee of any monies deposited with
it hereunder to the payment of or on account of the principal of or interest on the Securities or
Coupons, if at the time of such deposit a Responsible Officer of the Trustee did not have written
notice in accordance with Section 13.6 of any event prohibiting the making of such deposit by the
Issuer or if in the event of redemption, a Responsible Officer of the Trustee did not have such
written notice prior to the time that the notice of redemption pursuant to Section 12.2 was given
(which notice of redemption shall in no event be given more than 60 days prior to the date fixed
for redemption).

     Section 13.5 Holders of Securities Authorize Trustee to Effectuate Subordination of
Securities. Each Holder by his or her acceptance of a Security or Coupon authorizes and
directs the Trustee on his or her behalf to take such action as may be necessary or appropriate to
acknowledge or effectuate the subordination as provided in this Article 13 and appoints the Trustee
as attorney-in-fact for any and all such purposes, including, in the event of any dissolution,
winding up, liquidation or reorganization of the Issuer (whether in bankruptcy, insolvency or
receivership proceedings or upon an assignment for the benefit of creditors or otherwise) tending
towards liquidation of the business and assets of the Issuer, the immediate filing of a claim for
the unpaid balance of such Holder’s Securities or Coupons in the form required in said proceedings
and cause said claim to be approved. 

     Section 13.6 Notice to Trustee. Notwithstanding the provisions of this Article 13 or
any other provisions of this Indenture, the Trustee shall not be charged with the knowledge of the
existence of any facts which would prohibit the making of any payment of monies to or by the
Trustee, unless and until a Responsible Officer of the Trustee shall have received at the Corporate
Trust Office written notice from the Issuer or from the holder or the representative of any class
of Senior Indebtedness that such payment may
not be made under this Article 13 and, prior to the receipt of any such written notice, the
Trustee shall be entitled in all respects to assume that no such facts exist; provided, however,
that if at least two Business Days prior to the date upon which by the terms hereof any such monies
may become payable for any purpose (including, without limitation, the payment of either the cash
amount payable at maturity or

51

 

interest on any Security or Coupon), the Trustee shall not have
received with respect to such monies the notice provided for in this Section 13.6, then, anything
herein contained to the contrary notwithstanding, the Trustee shall have full power and authority
to receive such monies and to apply the same to the purpose for which they were received, and shall
not be affected by any notice to the contrary which may be received by it on or after such two
Business Days prior to such date.

     Section 13.7 Trustee May Hold Senior Indebtedness. Subject to the provisions of
Section 6.13, the Trustee shall be entitled to all the rights set forth in this Article 13 with
respect to any Senior Indebtedness which may at any time be held by it, to the same extent as any
other holder of Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee or any
Authenticating Agent of its right as such holder.

     Nothing in this Article shall apply to claims of, or payments to, the Trustee under or
pursuant to Section 5.3 or Section 6.6.

     Section 13.8 Applicability of Article 13 to Paying Agents. In case at any time any
paying agent other than the Trustee shall be appointed by the Issuer and be then acting hereunder,
the term “Trustee” as used in this Article 13 in such case (unless the context shall otherwise
require) be construed as extending to and including such paying agent within its meaning as fully
for all intents and purposes as if such paying agent were named in this Article 13 in place of the
Trustee.

     Section 13.9 Satisfaction and Discharge. Amounts deposited in trust with the Trustee
pursuant to and in accordance with Article 10 and not prohibited to be deposited under Section 13.2
when deposited shall not be subject to this Article 13.

52

 

          IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed as of
the date first written above.
