security interest created by the Loan Documents) under any indenture, mortgage,
contract, deed of trust, or other agreement to which any Borrower is a party or

4. Entire Agreement. This
Amendment and the Agreement embody the entire agreement between the parties
respecting the subject matter hereof and supersede all prior agreements,
proposals, communications and understandings relating to such subject matter.

     Section 3.03 Execution, Authentication, Delivery and Dating.

facsimile signature of its Chairman of the Board of Directors, its Chief Executive Officer,
President, one of its Vice Presidents or Treasurer. If the Person whose signature is on a Security
no longer holds that office at the time the Security is authenticated and delivered, the Security
shall nevertheless be valid.

               (b) At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Securities of any series executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and delivery of such
Securities and, if required pursuant to Section 3.01, a supplemental indenture or Company Order
setting forth the terms of the Securities of a series. The Trustee shall thereupon authenticate
and deliver such Securities without any further action by the Company. The Company Order shall
specify the amount of Securities to be authenticated and the date on which the original issue of
Securities is to be authenticated.

               (c) In authenticating the first Securities of any series and accepting the additional
responsibilities under this Indenture in relation to such Securities the Trustee shall receive, and
(subject to Section 11.02) shall be fully protected in relying upon an Officer’s Certificate and an
Opinion of Counsel, each prepared in accordance with Section 16.01 stating that the conditions
precedent, if any, provided for in the Indenture have been complied with.

               (d) The Trustee shall have the right to decline to authenticate and deliver the Securities
under this Section 3.03 if the issue of the Securities pursuant to this Indenture will

17

 

affect the
Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in
a manner which is not reasonably acceptable to the Trustee.

               (e) Each Security shall be dated the date of its authentication, except as otherwise provided
pursuant to Section 3.01 with respect to the Securities of such series.

               (f) Notwithstanding the provisions of Section 3.01 and of this Section 3.03, if all of the
Securities of any series are not to be originally issued at the same time, then the documents
required to be delivered pursuant to this Section 3.03 must be delivered only once prior to the
authentication and delivery of the first Security of such series;

               (g) If the Company shall establish pursuant to Section 3.01 that the Securities of a series
are to be issued in whole or in part in the form of one or more Global Securities, then the Company
shall execute and the Trustee shall authenticate and deliver one or more Global Securities that (i)
shall represent an aggregate amount equal to the aggregate principal amount of the Outstanding
Securities of such series to be represented by such Global Securities, (ii) shall be registered, if
in registered form, in the name of the Depositary for such Global Security or Global Securities or
the nominee of such Depositary, (iii) shall be delivered by the Trustee to such Depositary or
pursuant to such Depositary’s instruction and (iv) shall bear a legend substantially to the
following effect:

“THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER
REFERRED TO AND IS REGISTERED IN THE NAME OF THE DEPOSITARY OR A NOMINEE OF THE
DEPOSITARY, WHICH MAY BE TREATED BY THE COMPANY, THE TRUSTEE AND ANY AGENT THEREOF
AS OWNER AND HOLDER OF THIS SECURITY FOR ALL PURPOSES.

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF [THE
DEPOSITARY] TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR
PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF [THE NOMINEE OF THE
DEPOSITARY] OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF
[THE DEPOSITARY] (AND ANY PAYMENT HEREON IS MADE TO [THE NOMINEE OF THE DEPOSITARY]
OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF [THE
DEPOSITARY]), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR
TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, [THE NOMINEE OF THE
DEPOSITARY], HAS AN INTEREST HEREIN.

TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN
PART, BY THE DEPOSITARY TO A
NOMINEE OF THE

18

 

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 aggregate principal amount of each Global Security may from time to time be increased or
decreased by adjustments made on the records of the Security Custodian, as provided in this
Indenture.

               (h) Each Depositary designated pursuant to Section 3.01 for a Global Security in registered
form must, at the time of its designation and at all times while it serves as such Depositary, be a
clearing agency registered under the Exchange Act and any other applicable statute or regulation.

               (i) Members of, or participants in, the Depositary (“Members”) shall have no rights under this
Indenture with respect to any Global Security held on their behalf by the Depositary or by the
Security Custodian under such Global Security, and the Depositary may be treated by the Company,
the Trustee, the Paying Agent and the Registrar and any of their agents as the absolute owner of
such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein
shall prevent the Company, the Trustee, the Paying Agent or the Registrar or any of their agents
from giving effect to any written certification, proxy or other authorization furnished by the
Depositary or impair, as between the Depositary and its Members, the operation of customary
practices of the Depositary governing the exercise of the rights of an owner of a beneficial
interest in any Global Security. The Holder of a Global Security may grant proxies and otherwise
authorize any Person, including Members and Persons that may hold interests through Members, to
take any action that a Holder is entitled to take under this Indenture or the Securities.

               (j) No Security shall be entitled to any benefit under this Indenture or be valid or
obligatory for any purpose unless there appears on such Security a certificate of authentication
substantially in one of the forms provided for herein duly executed by the Trustee or by an
Authenticating Agent by manual or facsimile signature of an authorized signatory of the Trustee,
and such certificate upon any Security shall be conclusive evidence, and the only evidence, that
such Security has been duly authenticated and delivered hereunder and is entitled to the benefits
of this Indenture.

     Section 3.04 Temporary Securities.

               (a) Pending the preparation of definitive Securities of any series, the Company may execute,
and upon Company Order the Trustee shall authenticate and deliver, temporary Securities that are
printed, lithographed, typewritten, mimeographed or otherwise reproduced, in any authorized
denomination, substantially of the tenor of the definitive Securities in lieu of which they are
issued, in registered form and with such appropriate insertions, omissions, substitutions and other
variations as the officers executing such Securities may determine, as conclusively evidenced by
their execution of such Securities. Any such temporary
Security may be in the form of one or more Global Securities, representing all or a portion of
the Outstanding Securities of such series. Every such temporary Security shall be executed by the

19

 

Company and shall be authenticated and delivered by the Trustee upon the same conditions and in
substantially the same manner, and with the same effect, as the definitive Security or Securities
in lieu of which it is issued.

               (b) If temporary Securities of any series are issued, the Company will cause definitive
Securities of such series to be prepared without unreasonable delay. After the preparation of
definitive Securities of such series, the temporary Securities of such series shall be exchangeable
for definitive Securities of such series upon surrender of such temporary Securities at the office
or agency of the Company in a Place of Payment for such series, without charge to the Holder. Upon
surrender for cancellation of any one or more temporary Securities of any series, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount
of definitive Securities of the same series of authorized denominations and of like tenor. Until
so exchanged, the temporary Securities of any series shall in all respects be entitled to the same
benefits under this Indenture as definitive Securities of such series.

               (c) Upon any exchange of a portion of a temporary Global Security for a definitive Global
Security or for the Individual Securities represented thereby pursuant to this Section 3.04 or
Section 3.06, the temporary Global Security shall be endorsed by the Trustee to reflect the
reduction of the principal amount evidenced thereby, whereupon the principal amount of such
temporary Global Security shall be reduced for all purposes by the amount so exchanged and
endorsed.

     Section 3.05 Registrar and Paying Agent.

               (a) The Company will keep, at an office or agency to be maintained by it in a Place of Payment
where Securities may be presented for registration or presented and surrendered for registration of
transfer or of exchange, and where Securities of any series that are convertible or exchangeable
may be surrendered for conversion or exchange, as applicable (the “Registrar”), a security register
for the registration and the registration of transfer or of exchange of the Securities (the
registers maintained in such office and in any other office or agency of the Company in a Place of
Payment being herein sometimes collectively referred to as the “Register”), as in this Indenture
provided, which Register shall at all reasonable times be open for inspection by the Trustee. Such
Register shall be in written form or in any other form capable of being converted into written form
within a reasonable time. The Company may have one or more co-Registrars; the term “Registrar”
includes any co-registrar.

               (b) The Company shall enter into an appropriate agency agreement with any Registrar or
co-Registrar not a party to this Indenture. The agreement shall implement the provisions of this
Indenture that relate to such agent. The Company shall notify the Trustee of the name and address
of each such agent. If the Company fails to maintain a Registrar for any series, the Trustee shall
act as such and shall be entitled to appropriate compensation therefor pursuant to Section 11.01.
The Company or any Affiliate thereof may act as Registrar, co-Registrar or transfer agent.

20

 

               (c) The Company hereby appoints the Trustee at its Corporate Trust Office as Registrar in
connection with the Securities and this Indenture, until such time as another Person is appointed
as such.

     Section 3.06 Transfer and Exchange.

               (a) Transfer.

               (i) Upon surrender for registration of transfer of any Security of any series
at the Registrar the Company shall execute, and the Trustee or any Authenticating
Agent shall authenticate and deliver, in the name of the designated transferee, one
or more new Securities of the same series for like aggregate principal amount of any
authorized denomination or denominations. The transfer of any Security shall not be
valid as against the Company or the Trustee unless registered at the Registrar at
the request of the Holder, or at the request of his, her or its attorney duly
authorized in writing.

               (ii) Notwithstanding any other provision of this Section, unless and until it
is exchanged in whole or in part for the Individual Securities represented thereby,
a Global Security 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.

               (b) Exchange.

               (i) At the option of the Holder, Securities of any series (other than a Global
Security, except as set forth below) may be exchanged for other Securities of the
same series for like aggregate principal amount of any authorized denomination or
denominations, upon surrender of the Securities to be exchanged at the Registrar.

               (ii) Whenever any Securities are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Securities that the
Holder making the exchange is entitled to receive.

               (c) Exchange of Global Securities for Individual Securities. Except as provided below, owners
of beneficial interests in Global Securities will not be entitled to receive Individual Securities.

               (i) Individual Securities shall be issued to all owners of beneficial interests
in a Global Security in exchange for such interests if: (A) at any time the
Depositary for the Securities of a series notifies the Company that it is unwilling
or unable to continue as Depositary for the Securities of such series or if at any
time the Depositary for the Securities of such series shall no longer be

21

 

eligible under Section 3.03(h) and, in each case, a successor Depositary is not
appointed by the Company within 90 days of such notice, or (B) the Company executes
and delivers to the Trustee and the Registrar an Officer’s Certificate stating that
such Global Security shall be so exchangeable.

     In connection with the exchange of an entire Global Security for Individual Securities
pursuant to this subsection (c), such Global Security shall be deemed to be surrendered to
the Trustee for cancellation, and the Company shall execute, and the Trustee, upon receipt
of a Company Order for the authentication and delivery of Individual Securities of such
series, will authenticate and deliver to each beneficial owner identified by the Depositary
in exchange for its beneficial interest in such Global Security, an equal aggregate
principal amount of Individual Securities of authorized denominations.

               (ii) The owner of a beneficial interest in a Global Security will be entitled
to receive an Individual Security in exchange for such interest if an Event of
Default has occurred and is continuing. Upon receipt by the Security Custodian and
Registrar of instructions from the Holder of a Global Security directing the
Security Custodian and Registrar to (x) issue one or more Individual Securities in
the amounts specified to the owner of a beneficial interest in such Global Security
and (y) debit or cause to be debited an equivalent amount of beneficial interest in
such Global Security, subject to the rules and regulations of the Depositary:

                         (A) the Security Custodian and Registrar shall notify the
Company and the Trustee of such instructions, identifying the owner
and amount of such beneficial interest in such Global Security;

                         (B) the Company shall promptly execute and the Trustee, upon
receipt of a Company Order for the authentication and delivery of
Individual Securities of such series, shall authenticate and deliver
to such beneficial owner Individual Securities in an equivalent
amount to such beneficial interest in such Global Security; and

                         (C) the Security Custodian and Registrar shall decrease such
Global Security by such amount in accordance with the foregoing. In
the event that the Individual Securities are not issued to each such
beneficial owner promptly after the Registrar has received a request
from the Holder of a Global Security to issue such Individual
Securities, the Company expressly acknowledges, with respect to the
right of any Holder to pursue a remedy pursuant to Section 7.07
hereof, the right of any beneficial Holder of Securities to pursue
such remedy with respect to the portion of the Global Security that
represents such beneficial Holder’s Securities as if such Individual
Securities had been issued.

22

 

               (iii) If specified by the Company pursuant to Section 3.01 with respect to a
series of Securities, the Depositary for such series of Securities may surrender a
Global Security for such series of Securities in exchange in whole or in part for
Individual Securities of such series on such terms as are acceptable to the Company
and such Depositary. Thereupon, the Company shall execute, and the Trustee shall
authenticate and deliver, without service charge,

                         (A) to each Person specified by such Depositary a new
Individual Security or new Individual Securities of the same series,
of any authorized denomination as requested by such Person in
aggregate principal amount equal to and in exchange for such
Person’s beneficial interest in the Global Security; and

                         (B) to such Depositary a new Global Security in a denomination
equal to the difference, if any, between the principal amount of the
surrendered Global Security and the aggregate principal amount of
Individual Securities delivered to Holders thereof.

               (iv) In any exchange provided for in clauses (i) through (iii), the Company
will execute and the Trustee will authenticate and deliver Individual Securities in
registered form in authorized denominations.

               (v) Upon the exchange in full of a Global Security for Individual Securities,
such Global Security shall be canceled by the Trustee. Individual Securities issued
in exchange for a Global Security pursuant to this Section shall be registered in
such names and in such authorized denominations as the Depositary for such Global
Security, pursuant to instructions from its direct or indirect participants or
otherwise, shall instruct the Trustee. The Trustee shall deliver such Securities to
the Persons in whose names such Securities are so registered.

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

               (e) Every Security presented or surrendered for registration of transfer, or for exchange or
payment shall (if so required by the Company, the Trustee or the Registrar) be duly endorsed, or be
accompanied by a written instrument or instruments of transfer in form satisfactory to the Company,
the Trustee and the Registrar, duly executed by the Holder thereof or by his, her or its attorney
duly authorized in writing.

               (f) No service charge will be made for any registration of transfer or exchange of Securities.
The Company or the Trustee may require payment of a sum sufficient to cover any tax, assessment or
other governmental charge that may be imposed in connection with

23

 

any registration of transfer or exchange of Securities, other than those expressly provided in
this Indenture to be made at the Company’s own expense or without expense or charge to the Holders.

               (g) The Company shall not be required to (i) register, transfer or exchange Securities of any
series during a period beginning at the opening of business 15 days before the day of the
transmission of a notice of redemption of Securities of such series selected for redemption under
Section 4.03 and ending at the close of business on the day of such transmission, or (ii) register,
transfer or exchange any Security so selected for redemption in whole or in part, except the
unredeemed portion of any Security being redeemed in part.

               (h) Prior to the due presentation for registration of transfer or exchange of any Security,
the Company, the Trustee, the Paying Agent, the Registrar, any co-Registrar or any of their agents
may deem and treat the Person in whose name a Security is registered 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 all purposes whatsoever, and none of the Company, the
Trustee, the Paying Agent, the Registrar, any co-Registrar or any of their agents shall be affected
by any notice to the contrary.

               (i) In case a successor Company (“Successor Company”) has executed an indenture supplemental
hereto with the Trustee pursuant to Article XIV, any of the Securities authenticated or delivered
pursuant to such transaction may, from time to time, at the request of the Successor Company, be
exchanged for other Securities executed in the name of the Successor Company with such changes in
phraseology and form as may be appropriate, but otherwise identical to the Securities surrendered
for such exchange and of like principal amount; and the Trustee, upon Company Order of the
Successor Company, shall authenticate and deliver Securities as specified in such order for the
purpose of such exchange. If Securities shall at any time be authenticated and delivered in any
new name of a Successor Company pursuant to this Section 3.06 in exchange or substitution for or
upon registration of transfer of any Securities, such Successor Company, at the option of the
Holders but without expense to them, shall provide for the exchange of all Securities at the time
Outstanding for Securities authenticated and delivered in such new name.

               (j) Each Holder of a Security agrees to indemnify the Company and the Trustee against any
liability that may result from the transfer, exchange or assignment of such Holder’s Security in
violation of any provision of this Indenture and/or applicable United States federal or state
securities laws.

               (k) 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 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.

               (l) Neither the Trustee nor any agent of the Trustee shall have any responsibility for any
actions taken or not taken by the Depositary.

24

 

     Section 3.07 Mutilated, Destroyed, Lost and Stolen Securities.

               (a) If (i) any mutilated Security is surrendered to the Trustee at its Corporate Trust Office
or (ii) the Company and the Trustee receive evidence to their satisfaction of the destruction, loss
or theft of any Security, and there is delivered to the Company and the Trustee security or
indemnity satisfactory to them to save each of them and any Paying Agent harmless, and neither the
Company nor the Trustee receives notice that such Security has been acquired by a protected
purchaser, then the Company shall execute and upon Company Order the Trustee shall authenticate and
deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Security, a
new Security of the same series and of like tenor, form, terms and principal amount, bearing a
number not contemporaneously outstanding, that neither gain nor loss in interest shall result from
such exchange or substitution.

               (b) In case any such mutilated, destroyed, lost or stolen Security has become or is about to
become due and payable, the Company in its discretion may, instead of issuing a new Security, pay
the amount due on such Security in accordance with its terms.

               (c) Upon the issuance of any new Security under this Section, the Company may require the
payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in
respect thereto and any other expenses (including the fees and expenses of the Trustee) connected
therewith.

               (d) Every new Security of any series issued pursuant to this Section shall constitute an
original additional contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the
benefits of this Indenture equally and proportionately with any and all other Securities of that
series duly issued hereunder.

               (e) The provisions of this Section are exclusive and shall preclude (to the extent lawful) all
other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost
or stolen Securities.

          Section 3.08 Payment of Interest; Interest Rights Preserved.

               (a) Interest on any Security that is payable and is punctually paid or duly provided for on
any Interest Payment Date shall be paid to the Person in whose name such Security (or one or more
Predecessor Securities) is registered at the close of business on the Record Date for such interest
notwithstanding the cancellation of such Security upon any transfer or exchange subsequent to the
Record Date. Payment of interest on Securities shall be made at the Corporate Trust Office (except
as otherwise specified pursuant to Section 3.01) or, at the option of the Company, by check mailed
to the address of the Person entitled thereto as such address shall appear in the Register or, in
accordance with arrangements satisfactory to the Trustee, by wire transfer to an account designated
by the Holder.

               (b) Any interest on any Security that is payable but is not punctually paid or duly provided
for on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be
payable to the Holder on the relevant Record Date by virtue of his, her or

25

 

its having been such a Holder, and such Defaulted Interest may be paid by the Company, at its
election in each case, as provided in clause (i) or (ii) below:

               (i) The Company may elect to make payment of any Defaulted Interest to the
Persons in whose names such Securities (or their respective Predecessor Securities)
are registered at the close of business on a special record date for the payment of
such Defaulted Interest (a “Special Record Date”), which shall be fixed in the
following manner. The Company shall notify the Trustee in writing of the amount of
Defaulted Interest proposed to be paid on each such Security and the date of the
proposed payment, and at the same time the Company shall deposit with the Trustee an
amount of money equal to the aggregate amount proposed to be paid in respect of such
Defaulted Interest or shall make arrangements satisfactory to the Trustee for such
deposit prior to the date of the proposed payment, such money when deposited to be
held in trust for the benefit of the Persons entitled to such Defaulted Interest as
in this clause provided. Thereupon the Trustee shall fix a Special Record Date for
the payment of such Defaulted Interest which shall be not more than 15 calendar days
and not less than 10 calendar days prior to the date of the proposed payment and not
less than 10 calendar days after the receipt by the Trustee of the notice of the
proposed payment. The Trustee shall promptly notify the Company of such Special
Record Date and, in the name and at the expense of the Company, shall cause notice
of the proposed payment of such Defaulted Interest and the Special Record Date
therefor to be mailed, first-class postage prepaid, to the Holders of such
Securities at their addresses as they appear in the Register, not less than 10
calendar days prior to such Special Record Date. Notice of the proposed payment of
such Defaulted Interest and the Special Record Date therefor having been mailed as
aforesaid, such Defaulted Interest shall be paid to the Persons in whose names such
Securities (or their respective Predecessor Securities) are registered at the close
of business on such Special Record Date and shall no longer be payable pursuant to
the following clause (ii).

               (ii) The Company may make payment of any Defaulted Interest on Securities in
any other lawful manner not inconsistent with the requirements of any securities
exchange on which such Securities may be listed, and upon such notice as may be
required by such exchange, if, after notice given by the Company to the Trustee of
the proposed payment pursuant to this clause, such manner of payment shall be deemed
practicable by the Trustee.

               (c) Subject to the provisions set forth herein relating to Record Dates, each Security
delivered pursuant to any provision of this Indenture in exchange or substitution for, or upon
registration of transfer of, any other Security shall carry all the rights to interest accrued and
unpaid, and to accrue, which were carried by such other Security.

     Section 3.09 Cancellation. Unless otherwise specified pursuant to Section 3.01 for Securities of any series, all Securities
surrendered for payment, redemption, registration of transfer or exchange or credit against any
sinking fund or otherwise shall, if surrendered to any

26

 

Person other than the Trustee, be delivered
to the Trustee for cancellation and shall be promptly canceled by it and, if surrendered to the
Trustee, shall be promptly canceled by it. The Company may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder that the Company may
have acquired in any manner whatsoever, and all Securities so delivered shall be promptly canceled
by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities
canceled as provided in this Section, except as expressly permitted by this Indenture. The Trustee
shall dispose of all canceled Securities held by it in accordance with its then customary
procedures and deliver a certificate of such disposal to the Company upon its written request
therefor. The acquisition of any Securities by the Company shall not operate as a redemption or
satisfaction of the Indebtedness represented thereby unless and until such Securities are
surrendered to the Trustee for cancellation.

     Section 3.10 Computation of Interest. Except as otherwise specified pursuant to Section 3.01 for
Securities of any series, interest on the Securities of each series shall be computed on the basis
of a 360-day year of twelve 30-day months.

     Section 3.11 Currency of Payments in Respect of Securities.

               (a) Except as otherwise specified pursuant to Section 3.01 for Securities of any series,
payment of the principal of and premium, if any, and interest on Securities of such series will be
made in U.S. Dollars.

               (b) For purposes of any provision of the Indenture where the Holders of Outstanding Securities
may perform an action that requires that a specified percentage of the Outstanding Securities of
all series perform such action and for purposes of any decision or determination by the Trustee of
amounts due and unpaid for the principal of and premium, if any, and interest on the Securities of
all series in respect of which moneys are to be disbursed ratably, the principal of and premium, if
any, and interest on the Outstanding Securities denominated in a Foreign Currency will be the
amount in U.S. Dollars based upon exchange rates, determined as specified pursuant to Section 3.01
for Securities of such series, as of the date for determining whether the Holders entitled to
perform such action have performed it or as of the date of such decision or determination by the
Trustee, as the case may be.

               (c) Any decision or determination to be made regarding exchange rates shall be made by an
agent appointed by the Company; provided, that such agent shall accept such appointment in writing
and the terms of such appointment shall, in the opinion of the Company at the time of such
appointment, require such agent to make such determination by a method consistent with the method
provided pursuant to Section 3.01 for the making of such decision or determination. All decisions
and determinations of such agent regarding exchange rates shall, in the absence of manifest error,
be conclusive for all purposes and irrevocably binding upon the Company, the Trustee and all
Holders of the Securities.

     Section 3.12 Judgments. The Company may provide pursuant to Section 3.01 for Securities of any series
that (a) the obligation, if any, of the Company to pay the principal of, premium, if any, and
interest on the Securities of any series in a Foreign Currency or U.S. Dollars (the “Designated
Currency”) as may be specified pursuant to Section 3.01 is of the

27

 

essence and agrees that, to the
fullest extent possible under applicable law, judgments in respect of such Securities shall be
given in the Designated Currency; (b) the obligation of the Company to make payments in the
Designated Currency of the principal of and premium, if any, and interest on such Securities shall,
notwithstanding any payment in any other Currency (whether pursuant to a judgment or otherwise), be
discharged only to the extent of the amount in the Designated Currency that the Holder receiving
such payment may, in accordance with normal banking procedures, purchase with the sum paid in such
other Currency (after any premium and cost of exchange) on the business day in the country of issue
of the Designated Currency or in the international banking community (in the case of a composite
currency) immediately following the day on which such Holder receives such payment; (c) if the
amount in the Designated Currency that may be so purchased for any reason falls short of the amount
originally due, the Company shall pay such additional amounts as may be necessary to compensate for
such shortfall; and (d) any obligation of the Company not discharged by such payment shall be due
as a separate and independent obligation and, until discharged as provided herein, shall continue
in full force and effect.

     Section 3.13 CUSIP Numbers. The Company in issuing any Securities may use CUSIP, ISIN or other similar
numbers, if then generally in use, and thereafter with respect to such series, the Trustee may use
such numbers in any notice of redemption or exchange with respect to such series 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 Company will promptly
notify the Trustee in writing of any change in the CUSIP, ISIN or other similar numbers.

ARTICLE IV

REDEMPTION OF SECURITIES

     Section 4.01 Applicability of Right of Redemption. Redemption of Securities (other than pursuant to a
sinking fund, amortization or analogous provision) permitted by the terms of any series of
Securities shall be made (except as otherwise specified pursuant to Section 3.01 for Securities of
any series) in accordance with this Article; provided, however, that if any such terms of a series
of Securities shall conflict with any provision of this Article, the terms of such series shall
govern.

     Section 4.02 Selection of Securities to be Redeemed.

               (a) If the Company shall at any time elect to redeem all or any portion of the Securities of a
series then Outstanding, it shall at least 30 days prior to the Redemption Date fixed by the
Company (unless a shorter period shall be satisfactory to the Trustee) notify the Trustee of such
Redemption Date and of the principal amount of Securities to be redeemed, and thereupon the Trustee
shall select, by lot or in such other manner as the Trustee shall deem appropriate and which may
provide for the selection for redemption of a portion of the principal amount of any Security of
such series; provided that the unredeemed portion of the principal

28

 

amount of any Security shall be
in an authorized denomination (which shall not be less than the minimum authorized denomination)
for such Security. In any case where more than one Security of such series is registered in the
same name, the Trustee may treat the aggregate principal amount so registered as if it were
represented by one Security of such series. The Trustee shall, as soon as practicable, notify the
Company in writing of the Securities and portions of Securities so selected.

               (b) For all purposes of this Indenture, unless the context otherwise requires, all provisions
relating to the redemption of Securities shall relate, in the case of any Security redeemed or to
be redeemed only in part, to the portion of the principal amount of such Security that has been or
is to be redeemed. If the Company shall so direct, Securities registered in the name of the
Company, any Affiliate or any Subsidiary thereof shall not be included in the Securities selected
for redemption.

     Section 4.03 Notice of Redemption.

               (a) Notice of redemption shall be given by the Company or, at the Company’s written request
(provided to the Trustee at least ten days prior to the date the notice is to be sent), by the
Trustee in the name and at the expense of the Company, not less than 30 nor more than 60 days prior
to the Redemption Date, to the Holders of Securities of any series to be redeemed in whole or in
part pursuant to this Article, in the manner provided in Section 16.04. Any notice so given shall
be conclusively presumed to have been duly given, whether or not the Holder receives such notice.
Failure to give such notice, or any defect in such notice to the Holder of any Security of a series
designated for redemption, in whole or in part, shall not affect the sufficiency of any notice of
redemption with respect to the Holder of any other Security of such series.

               (b) All notices of redemption shall identify the Securities to be redeemed (including CUSIP,
ISIN or other similar numbers, if available) and shall state:

               (i) such election by the Company to redeem Securities of such series pursuant
to provisions contained in this Indenture or the terms of the Securities of such
series or a supplemental indenture establishing such series, if such be the case;

               (ii) the Redemption Date;

               (iii) the Redemption Price;

               (iv) if less than all Outstanding Securities of any series are to be redeemed,
the identification (and, in the case of partial redemption, the principal amounts)
of the Securities of such series to be redeemed;

               (v) that on the Redemption Date the Redemption Price will become due and
payable upon each such Security to be redeemed, and that, if applicable, interest
thereon shall cease to accrue on and after said date;

29

 

               (vi) the Place or Places of Payment where such Securities are to be surrendered
for payment of the Redemption Price;

               (vii) that the redemption is for a sinking fund, if such is the case; and

               (viii) that, unless the Company defaults in making such redemption payment,
interest on Securities (or portion thereof) called for redemption ceases to accrue
on and after the redemption date.

     Section 4.04 Deposit of Redemption Price. Prior to the Redemption Date for any Securities, the Company
shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own
Paying Agent, segregate and hold in trust as provided in Section 6.03) an amount of money in the
Currency in which such Securities are denominated (except as provided pursuant to Section 3.01)
sufficient to pay the Redemption Price of such Securities or any portions thereof that are to be
redeemed on that date.

     Section 4.05 Securities Payable on Redemption Date. Notice of redemption having been given as
aforesaid, any Securities so to be redeemed shall, on the Redemption Date, become due and payable
at the Redemption Price and from and after such date (unless the Company shall Default in the
payment of the Redemption Price) such Securities shall cease to bear interest. Upon surrender of
any such Security for redemption in accordance with said notice, such Security shall be paid by the
Company at the Redemption Price; provided, however, that (unless otherwise provided pursuant to
Section 3.01) installments of interest that have a Stated Maturity on or prior to the Redemption
Date for such Securities shall be payable according to the terms of such Securities and the
provisions of Section 3.08.

          If any Security called for redemption shall not be so paid upon surrender thereof for
redemption, the principal thereof and premium, if any, thereon shall, until paid, bear interest
from the Redemption Date at the rate prescribed therefor in the Security.

     Section 4.06 Deposit of Redemption Price. On or prior to the redemption date, in each case, not later
than 11:00 a.m., New York City time, the Company shall deposit with the Paying Agent (or, if the
Company or a Subsidiary is the Paying Agent, shall segregate and hold in trust) money sufficient to
pay the redemption price of and accrued interest (subject to the right of Holders of record on the
relevant record date to
receive interest due on the related interest payment date that is on or prior to the date of
redemption) on all Securities to be redeemed on that date other than Securities or portions of
Securities called for redemption that have been delivered by the Company to the Trustee for
cancellation.

     Section 4.07 Securities Redeemed in Part. Any Security that is to be redeemed only in part shall be
surrendered at the Corporate Trust Office or such other office or agency of the Company as is
specified pursuant to Section 3.01 with, if the Company, the Registrar or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to the Company, the
Registrar and the Trustee duly executed by the Holder thereof or his, her or its attorney duly
authorized in writing, and the Company shall execute, and the Trustee shall authenticate and
deliver to the Holder of such Security without service charge, a new Security or

30

 

Securities of the
same series, of like tenor and form, of any authorized denomination as requested by such Holder in
aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered; except that if a Global Security is so surrendered, the Company shall
execute, and the Trustee shall authenticate and deliver to the Depositary for such Global Security,
without service charge, a new Global Security in a denomination equal to and in exchange for the
unredeemed portion of the principal of the Global Security so surrendered. In the case of a
Security providing appropriate space for such notation, at the option of the Holder thereof, the
Trustee, in lieu of delivering a new Security or Securities as aforesaid, may make a notation on
such Security of the payment of the redeemed portion thereof.

ARTICLE V

SINKING FUNDS

     Section 5.01 Applicability of Sinking Fund.

               (a) Redemption of Securities permitted or required pursuant to a sinking fund for the
retirement of Securities of a series by the terms of such series of Securities shall be made in
accordance with such terms of such series of Securities and this Article, except as otherwise
specified pursuant to Section 3.01 for Securities of such series, provided, however, that if any
such terms of a series of Securities shall conflict with any provision of this Article, the terms
of such series shall govern.

               (b) The minimum amount of any sinking fund payment provided for by the terms of 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 Securities of any series is herein referred to
as an “Optional Sinking Fund Payment.” If provided for by the terms of Securities of any series,
the cash amount of any Mandatory Sinking Fund Payment may be subject to reduction as provided in
Section 5.02.

     Section 5.02 Mandatory Sinking Fund Obligation. The Company may, at its option, satisfy any Mandatory Sinking Fund Payment obligation, in whole
or in part, with respect to a particular series of Securities by (a) delivering to the Trustee
Securities of such series in transferable form theretofore purchased or otherwise acquired by the
Company or redeemed at the election of the Company pursuant to Section 4.03 or (b) receiving credit
for Securities of such series (not previously so credited) acquired by the Company and theretofore
delivered to the Trustee. The Trustee shall credit such Mandatory Sinking Fund Payment obligation
with an amount equal to the Redemption Price specified in such Securities for redemption through
operation of the sinking fund and the amount of such Mandatory Sinking Fund Payment shall be
reduced accordingly. If the Company shall elect to so satisfy any Mandatory Sinking Fund Payment
obligation, it shall deliver to the Trustee not less than 45 days prior to the relevant sinking
fund payment date an Officer’s Certificate, which shall designate the Securities (and portions
thereof, if any) so delivered or credited and which shall be accompanied by such Securities (to the
extent not theretofore delivered) in transferable form. In case of the failure of

31

 

the Company, at
or before the time so required, to give such notice and deliver such Securities the Mandatory
Sinking Fund Payment obligation shall be paid entirely in moneys.

     Section 5.03 Optional Redemption at Sinking Fund Redemption Price. In addition to the sinking fund
requirements of Section 5.02, to the extent, if any, provided for by the terms of a particular
series of Securities, the Company may, at its option, make an Optional Sinking Fund Payment with
respect to such Securities. Unless otherwise provided by such terms, (a) to the extent that the
right of the Company to make such Optional Sinking Fund Payment shall not be exercised in any year,
it shall not be cumulative or carried forward to any subsequent year, and (b) such optional payment
shall operate to reduce the amount of any Mandatory Sinking Fund Payment obligation as to
Securities of the same series. If the Company intends to exercise its right to make such optional
payment in any year it shall deliver to the Trustee not less than 45 days prior to the relevant
sinking fund payment date an Officer’s Certificate stating that the Company will exercise such
optional right, and specifying the amount which the Company will pay on or before the next
succeeding sinking fund payment date. Such Officer’s Certificate shall also state that no Event of
Default has occurred and is continuing.

     Section 5.04 Application of Sinking Fund Payment.

               (a) If the sinking fund payment or payments made in funds pursuant to either Section 5.02 or
5.03 with respect to a particular series of Securities plus any unused balance of any preceding
sinking fund payments made in funds with respect to such series shall exceed $50,000 (or a lesser
sum if the Company shall so request, or such equivalent sum for Securities denominated other than
in U.S. Dollars), it shall be applied by the Trustee on the sinking fund payment date next
following the date of such payment, unless the date of such payment shall be a sinking fund payment
date, in which case such payment shall be applied on such sinking fund payment date, to the
redemption of Securities of such series at the redemption price specified pursuant to Section
4.03(b). The Trustee shall select, in the manner provided in Section 4.02, for redemption on such
sinking fund payment date, a sufficient principal amount of Securities of such series to absorb
said funds, as nearly as may be, and shall, at the expense and in the name of the Company,
thereupon cause notice of redemption of the Securities to be given in substantially the manner
provided in Section 4.03(a) for the redemption of Securities in part at
the option of the Company, except that the notice of redemption shall also state that the
Securities are being redeemed for the sinking fund. Any sinking fund moneys not so applied by the
Trustee to the redemption of Securities of such series shall be added to the next sinking fund
payment received in funds by the Trustee and, together with such payment, shall be applied in
accordance with the provisions of this Section 5.04. Any and all sinking fund moneys held by the
Trustee on the last sinking fund payment date with respect to Securities of such series, and not
held for the payment or redemption of particular Securities of such series, shall be applied by the
Trustee to the payment of the principal of the Securities of such series at Maturity.

               (b) On or prior to each sinking fund payment date, the Company shall pay to the Trustee a sum
equal to all interest accrued to but not including the date fixed for redemption on Securities to
be redeemed on such sinking fund payment date pursuant to this Section 5.04.

32

 

               (c) The Trustee shall not redeem any Securities of a series with sinking fund moneys or mail
any notice of redemption of Securities of such series by operation of the sinking fund during the
continuance of a Default in payment of interest on any Securities of such series or of any Event of
Default (other than an Event of Default occurring as a consequence of this paragraph) of which a
Responsible Officer of the Trustee has actual knowledge, except that if the notice of redemption of
any Securities of such series shall theretofore have been mailed in accordance with the provisions
hereof, the Trustee shall redeem such Securities if funds sufficient for that purpose shall be
deposited with the Trustee in accordance with the terms of this Article. Except as aforesaid, any
moneys in the sinking fund at the time any such Default or Event of Default shall occur and any
moneys thereafter paid into the sinking fund shall, during the continuance of such Default or Event
of Default, be held as security for the payment of all the Securities of such series; provided,
however, that in case such Default or Event of Default shall have been cured or waived as provided
herein, such moneys shall thereafter be applied on the next sinking fund payment date on which such
moneys are required to be applied pursuant to the provisions of this Section 5.04.

ARTICLE VI

PARTICULAR COVENANTS OF THE COMPANY

          The Company hereby covenants and agrees as follows:

     Section 6.01 Payments of Securities. The Company will duly and punctually pay the principal of and
premium, if any, on each series of Securities, and the interest which shall have accrued thereon,
at the dates and place and in the manner provided in the Securities and in this Indenture.
Principal and interest shall be considered paid on the date due if on such date the Trustee or the
Paying Agent holds in accordance with this Indenture money sufficient to pay all principal and
interest then due.

          The Company shall pay interest on overdue principal at the rate specified therefor in the
Securities, if any, and it shall pay such interest on overdue installments of interest, if any, at
the rate borne by the Securities to the extent lawful.

     Section 6.02 Paying Agent.

               (a) The Company will maintain in each Place of Payment for any series of Securities, if any,
an office or agency where Securities may be presented or surrendered for payment, where Securities
of such series may be surrendered for registration of transfer or exchange and where notices and
demands to or upon the Company in respect of the Securities and this Indenture may be served (the
“Paying Agent”). The Company will give prompt written notice to the Trustee of the location, and
any change in the location, of such office or agency. If at any time the Company shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate
Trust Office of the Trustee, and the Company hereby appoints the Trustee as Paying Agent to receive
all presentations, surrenders, notices and demands.

33

 

               (b) The Company may also from time to time designate different or additional offices or
agencies where the Securities of any series may be presented or surrendered for any or all such
purposes (in or outside of such Place of Payment), and may from time to time rescind any such
designations; provided, however, that no such designation or rescission shall in any manner relieve
the Company of its obligations described in the preceding paragraph. The Company will give prompt
written notice to the Trustee of any such additional designation or rescission of designation and
of any change in the location of any such different or additional office or agency. The Company
shall enter into an appropriate agency agreement with any Paying Agent not a party to this
Indenture. The agreement shall implement the provisions of this Indenture that relate to such
agent. The Company shall notify the Trustee of the name and address of each such agent. The
Company or any Affiliate thereof may act as Paying Agent.

     Section 6.03 To Hold Payment in Trust.

               (a) If the Company or an Affiliate thereof shall at any time act as Paying Agent with respect
to any series of Securities, then, on or before the date on which the principal of and premium, if
any, or interest on any of the Securities of that series by their terms or as a result of the
calling thereof for redemption shall become payable, the Company or such Affiliate will segregate
and hold in trust for the benefit of the Holders of such Securities or the Trustee a sum sufficient
to pay such principal and premium, if any, or interest which shall have so become payable until
such sums shall be paid to such Holders or otherwise disposed of as herein provided, and will
notify the Trustee of its action or failure to act in that regard. Upon any proceeding under any
federal bankruptcy laws with respect to the Company or any Affiliate thereof, if the Company or
such Affiliate is then acting as Paying Agent, the Trustee shall replace the Company or such
Affiliate as Paying Agent.

               (b) If the Company shall appoint, and at the time have, a Paying Agent for the payment of the
principal of and premium, if any, or interest on any series of Securities, then prior to 11:00
a.m., New York City time on the date on which the principal of and premium, if any, or interest on
any of the Securities of that series shall become payable as aforesaid, whether by their terms or
as a result of the calling thereof for redemption, the Company will deposit with such Paying Agent
a sum sufficient to pay such principal and premium, if any, or interest, such
sum to be held in trust for the benefit of the Holders of such Securities or the Trustee, and
(unless such Paying Agent is the Trustee), the Company or any other obligor of such Securities will
promptly notify the Trustee of its payment or failure to make such payment.

               (c) If the Paying Agent shall be other than the Trustee, the Company will cause such Paying
Agent 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 6.03, that such Paying Agent shall:

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

34

 

                    (ii) give to the Trustee notice of any Default by the Company or any other
obligor upon the Securities of that series in the making of any payment of the
principal of and premium, if any, or interest on the Securities of that series; and

                    (iii) at any time during the continuance of any such Default, upon the written
request of the Trustee, pay to the Trustee all sums so held in trust by such Paying
Agent.

               (d) Anything in this Section 6.03 to the contrary notwithstanding, the Company may at any
time, for the purpose of obtaining a release, satisfaction or discharge of this Indenture or for
any other reason, pay or cause to be paid to the Trustee all sums held in trust by the Company or
by any Paying Agent other than the Trustee as required by this Section 6.03, such sums to be held
by the Trustee upon the same trusts as those upon which such sums were held by the Company or such
Paying Agent.

               (e) Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of and premium, if any, or interest on any Security of any
series 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 Company upon Company Order along with any interest
that has accumulated thereon as a result of such money being invested at the direction of the
Company, or (if then held by the Company) shall be discharged from such trust, and the Holder of
such Security shall thereafter, as an unsecured general creditor, look only to the Company for
payment of such amounts without interest thereon, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall
thereupon cease.

     Section 6.04 Merger, Consolidation and Sale of Assets. Except as otherwise provided as contemplated by
Section 3.01 with respect to any series of Securities:

               (a) For so long as any Securities are outstanding, the Company may not consolidate with or
merge into any other corporation or convey or transfer its properties and assets substantially as
an entirety to any Person, unless:

                    (i) the successor Person (the “Surviving Person”) shall be a corporation
organized and existing under the laws of the United States (or any State thereof or
the District of Columbia) and shall expressly assume, by a supplemental indenture,
the due and punctual payment of the principal of and interest on all the outstanding
Securities and the performance of every covenant in this Indenture on the part of
the Company to be performed or observed;

                    (ii) immediately after giving effect to such transaction, no Default or Event
of Default shall have happened and be continuing; and

                    (iii) the Company shall have delivered to the Trustee an Officer’s Certificate
and Opinion of Counsel stating that such consolidation,

35

 

merger, conveyance or
transfer and such supplemental indenture comply with this Section 6.04 relating to
such transaction.

               (b) In case of any consolidation, merger conveyance or transfer (other than a lease) that
complies with Section 6.04(a), the Surviving Person will succeed to and be substituted for the
Company as obligor on the Securities, with the same effect as if it had been named in this
Indenture as such obligor.

     Section 6.05 Compliance Certificate. Except as otherwise provided as contemplated by Section 3.01 with
respect to any series of Securities, the Company shall furnish to the Trustee annually, within 120
days after the end of each fiscal year commencing the fiscal year in which the first series of
Securities is issued hereunder, a brief certificate from the principal executive officer, principal
financial officer or principal accounting officer as to his or her knowledge of the Company’s
compliance with all conditions and covenants under this Indenture (which compliance shall be
determined without regard to any period of grace or requirement of notice provided under this
Indenture) and, in the event of any Default, specifying each such Default and the nature and status
thereof of which such person may have knowledge. Such certificates need not comply with Section
16.01 of this Indenture.

     Section 6.06 Conditional Waiver by Holders of Securities. Anything in this Indenture to the contrary
notwithstanding, the Company may fail or omit in any particular instance to comply with a covenant
or condition set forth herein with respect to any series of Securities if the Company shall have
obtained and filed with the Trustee, prior to the time of such failure or omission, evidence (as
provided in Article VIII) of the consent of the Holders of a majority in aggregate principal amount
of the Securities of such series at the time Outstanding, either waiving such compliance in such
instance or generally waiving compliance with such covenant or condition, but no such waiver shall
extend to or affect such covenant or condition except to the extent so expressly waived, or impair
any right consequent thereon and,
until such waiver shall have become effective, the obligations of the Company and the duties of the
Trustee in respect of any such covenant or condition shall remain in full force and effect.

     Section 6.07 Corporate Existence. Subject to Section 6.04 hereof, the Company shall do or cause to be
done all things necessary to preserve and keep in full force and effect:

               (a) its corporate existence, and the corporate, partnership or other existence of each of its
Subsidiaries, in accordance with the respective organizational documents (as the same may be
amended from time to time) of the Company or any such Subsidiary; and

               (b) the rights (charter and statutory), licenses and franchises of the Company and its
Subsidiaries; provided, however, that the Company shall not be required to preserve any such right,
license or franchise, or the corporate, partnership or other existence of any of its Subsidiaries,
if the Board of Directors in its sole judgment shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a
whole.

     Section 6.08 Statement by Officers as to Default. The Company shall deliver to the Trustee as soon as
possible and in any event within 30 days after the Company becomes aware of

36

 

the occurrence of any
Event of Default or an event which, with the giving of notice or the lapse of time or both, would
constitute an Event of Default, an Officer’s Certificate setting forth the details of such Event of
Default or Default and the action which the Company proposes to take with respect thereto.

ARTICLE VII

REMEDIES OF TRUSTEE AND SECURITYHOLDERS

     Section 7.01 Events of Default. The term “Event of Default” as used in this Indenture with respect to
Securities of any series shall mean one of the following described events unless it is either
inapplicable to a particular series or it is specifically deleted or modified in the manner
contemplated in Section 3.01:

               (a) the failure of the Company to pay any installment of interest on any Security of such
series when and as the same shall become payable, which failure shall have continued unremedied for
a period of 30 days;

               (b) the failure of the Company to pay the principal of (and premium, if any, on) any Security
of such series, when and as the same shall become payable, whether at Maturity as therein
expressed, by call for redemption (otherwise than pursuant to a sinking fund), by declaration as
authorized by this Indenture or otherwise;

               (c) the failure of the Company to pay a sinking fund installment, if any, when and as the same
shall become payable by the terms of a Security of such series, which failure shall have continued
unremedied for a period of 30 days;

               (d) the failure of the Company, subject to the provisions of Section 6.06, to perform any
covenants or agreements contained in this Indenture (including any indenture supplemental hereto
pursuant to which the Securities of such series were issued as contemplated by Section 3.01) (other
than a covenant or agreement which has been expressly included in this Indenture solely for the
benefit of a series of Securities other than that series and other than a covenant or agreement a
default in the performance of which is elsewhere in this Section 7.01 specifically addressed),
which failure shall not have been remedied, or without provision deemed to be adequate for the
remedying thereof having been made, for a period of 90 days after written notice shall have been
given to the Company by the Trustee or shall have been given to the Company and the Trustee by
Holders of 25% or more in aggregate principal amount of the Securities of such series then
Outstanding, specifying such failure, requiring the Company to remedy the same and stating that
such notice is a “Notice of Default” hereunder;

               (e) the entry by a court having jurisdiction in the premises of a decree or order for relief
in respect of the Company in an involuntary case under the federal bankruptcy laws, as now or
hereafter constituted, or any other applicable federal or state bankruptcy, insolvency or other
similar law now or hereafter in effect, or appointing a receiver, liquidator, assignee, custodian,
trustee or sequestrator (or similar official) of the Company or of substantially all the property
of the Company or ordering the winding-up or liquidation of its

37

 

affairs and such decree or order
shall remain unstayed and in effect for a period of 90 consecutive days;

               (f) the commencement by the Company of a voluntary case under the federal bankruptcy laws, as
now or hereafter constituted, or any other applicable federal or state bankruptcy, insolvency or
other similar law now or hereafter in effect, or the consent by the Company to the entry of an
order for relief in an involuntary case under any such law, or the consent by the Company to the
appointment of or taking possession by a receiver, liquidator, assignee, trustee, custodian or
sequestrator (or similar official) of the Company or of substantially all the property of the
Company or the making by it of an assignment for the benefit of creditors or the admission by it in
writing of its inability to pay its debts generally as they become due, or the taking of corporate
action by the Company in furtherance of any action; or

               (g) the occurrence of any other Event of Default with respect to Securities of such series as
provided in Section 3.01;

provided, however, that no event described in clause (d) or (other than with respect to a payment
default) (g) above shall constitute an Event of Default hereunder until a Responsible Officer of
the Trustee’s has actual knowledge thereof or until a written notice of any such event is received
by the Trustee at the Corporate Trust Office, and such notice refers to the facts underlying such
event, the Securities generally, the Company and the Indenture.

          Notwithstanding the foregoing provisions of this Section 7.01, if the principal or any premium
or interest on any Security is payable in a Currency other than the Currency of the United States
and such Currency is not available to the Company for making payment thereof due to the imposition
of exchange controls or other circumstances beyond the control of the Company, the Company will be
entitled to satisfy its obligations to Holders of the Securities by making such payment in the
Currency of the United States in an amount equal to the Currency of the United States equivalent of
the amount payable in such other Currency, as determined by the Company’s agent in accordance with
Section 3.11(c) hereof by reference to the noon buying rate in The City of New York for cable
transfers for such Currency (“Exchange Rate”), as such Exchange Rate is reported or otherwise made
available by the Federal Reserve Bank of New York on the date of such payment, or, if such rate is
not then available, on the basis of the most recently available Exchange Rate. Notwithstanding the
foregoing provisions of this Section 7.01, any payment made under such circumstances in the
Currency of the United States where the required payment is in a Currency other than the Currency
of the United States will not constitute an Event of Default under this Indenture.

     Section 7.02 Acceleration; Rescission and Annulment.

               (a) Except as otherwise provided as contemplated by Section 3.01 with respect to any series of
Securities, if any one or more of the above-described Events of Default (other than an Event of
Default specified in Section 7.01(e) or 7.01(f)) shall happen with respect to Securities of any
series at the time Outstanding, then, and in each and every such case, during the continuance of
any such Event of Default, the Trustee or the Holders of 25% or more in principal amount of the
Securities of such series then Outstanding may declare the principal (or,

38

 

if the Securities of that
series are Original Issue Discount Securities, such portion of the principal amount as may be
specified in the terms of that series) of and all accrued but unpaid interest on all the Securities
of such series then Outstanding to be due and payable immediately by a notice in writing to the
Company (and to the Trustee if given by Holders), and upon any such declaration such principal
amount (or specified amount) shall become immediately due and payable. If an Event of Default
specified in Section 7.01(e) or 7.01(f) occurs and is continuing, then in every such case, the
principal amount of all of the Securities of that series then Outstanding shall automatically, and
without any declaration or any other action on the part of the Trustee or any Holder, become due
and payable immediately. Upon payment of such amounts in the Currency in which such Securities are
denominated (subject to Section 7.01 and except as otherwise provided pursuant to Section 3.01),
all obligations of the Company in respect of the payment of principal of and interest on the
Securities of such series shall terminate.

               (b) The provisions of Section 7.02(a), however, are subject to the condition that, at any time
after the principal of all the Securities of such series, to which any one or more of the
above-described Events of Default is applicable, shall have been so declared to be due and payable,
and before a judgment or decree for payment of the money due has been obtained by the Trustee as
hereinafter provided in this Article, the Event of Default giving rise to such declaration of
acceleration shall, without further act, be deemed to have been waived, and such declaration and
its consequences shall, without further act, be deemed to have been rescinded and annulled, if:

               (i) the Company has paid or deposited with the Trustee or Paying Agent a sum in
the Currency in which such Securities are denominated (subject to Section 7.01 and
except as otherwise provided pursuant to Section 3.01) sufficient to pay

               (A) all amounts owing the Trustee and any predecessor trustee
hereunder under Section 11.01(a) (provided, however, that all sums
payable under this clause (A) shall be paid in U.S. Dollars);

               (B) all arrears of interest, if any, upon all the Securities of
such series (with interest, to the extent that interest thereon
shall be legally enforceable, on any overdue installment of interest
at the rate borne by such Securities at the rate or rates prescribed
therefor in such Securities); and

               (C) the principal of and premium, if any, on any Securities of
such series that have become due otherwise than by such declaration
of acceleration and interest thereon;

               (ii) every other Default and Event of Default with respect to Securities of
that series, other than the non-payment of the principal of Securities

39

 

of that
series which have become due solely by such declaration of acceleration, have been
cured or waived as provided in Section 7.06.

               (c) No such rescission shall affect any subsequent default or impair any right consequent
thereon.

               (d) 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 7.03 Other Remedies. If the Company shall fail for a period of 30 days to pay any installment
of interest on the Securities of any series or shall fail to pay the principal of and premium, if
any, on any of the Securities of such series when and as the same shall become due and payable,
whether at Maturity, or by call for redemption (other than pursuant to the sinking fund), by
declaration as authorized by this Indenture, or otherwise, or shall fail for a period of 30 days to
make any required sinking fund payment as to a series of Securities, then, upon demand of the
Trustee, the
Company will pay to the Paying Agent for the benefit of the Holders of Securities of such series
then Outstanding the whole amount which then shall have become due and payable on all the
Securities of such series, with interest on the overdue principal and premium, if any, and (so far
as the same may be legally enforceable) on the overdue installments of interest at the rate borne
by the Securities of such series, and all amounts owing the Trustee and any predecessor trustee
hereunder under Section 11.01(a).

          In case the Company 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 proceeding at law or in equity for the collection of the sums so due and unpaid, and may
prosecute any such action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company or any other obligor upon the Securities of such
series, and collect the moneys adjudged or decreed to be payable out of the property of the Company
or any other obligor upon the Securities of such series, wherever situated, in the manner provided
by law. Every recovery of judgment in any such action or other proceeding, subject to the payment
to the Trustee of all amounts owing the Trustee and any predecessor trustee hereunder under Section
11.01(a), shall be for the ratable benefit of the Holders of such series of Securities which shall
be the subject of such action or proceeding. All rights of action upon or under any of the
Securities or this Indenture may be enforced by the Trustee without the possession of any of the
Securities and without the production of any thereof at any trial or any proceeding relative
thereto.

     Section 7.04 Trustee as Attorney-in-Fact. The Trustee is hereby appointed, and each and every Holder of
the Securities, by receiving and holding the same, shall be conclusively

40

 

deemed to have appointed
the Trustee, the true and lawful attorney-in-fact of such Holder, with authority to make or file
(whether or not the Company shall be in Default in respect of the payment of the principal of, or
interest on, any of the Securities), in its own name and as trustee of an express trust or
otherwise as it shall deem advisable, in any receivership, insolvency, liquidation, bankruptcy,
reorganization or other judicial proceeding relative to the Company or any other obligor upon the
Securities or to their respective creditors or property, any and all claims, proofs of claim,
proofs of debt, petitions, consents, other papers and documents and amendments of any thereof, as
may be necessary or advisable in order to have the claims of the Trustee and any predecessor
trustee hereunder and of the Holders of the Securities allowed in any such proceeding and to
collect and receive any moneys or other property payable or deliverable on any such claim, and to
execute and deliver any and all other papers and documents and to do and perform any and all other
acts and things, as it may deem necessary or advisable in order to enforce in any such proceeding
any of the claims of the Trustee and any predecessor trustee hereunder and of any of such Holders
in respect of any of the Securities; and any receiver, assignee, trustee, custodian or debtor in
any such proceeding is hereby authorized, and each and every taker or Holder of the Securities, by
receiving and holding the same, shall be conclusively deemed to have authorized any such receiver,
assignee, trustee, custodian or debtor, to make any such payment or delivery only to or on the
order of the Trustee, and to pay to the Trustee any amount due it and any predecessor trustee
hereunder under Section 11.01(a); provided, however, that nothing herein contained shall be deemed
to authorize or empower the Trustee to consent to or accept or adopt, on behalf of any
Holder of Securities, any plan of reorganization or readjustment affecting the Securities or the
rights of any Holder thereof, or to authorize or empower the Trustee to vote in respect of the
claim of any Holder of any Securities in any such proceeding.

     Section 7.05 Priorities. Any moneys or properties collected by the Trustee with respect to a series of
Securities under this Article VII shall be applied in the order following, at the date or dates
fixed by the Trustee for the distribution of such moneys or properties and, in the case of the
distribution of such moneys or properties on account of the Securities of any series, upon
presentation of the Securities of such series, and stamping thereon the payment, if only partially
paid, and upon surrender thereof, if fully paid:

     First: To the payment of all amounts due to the Trustee and any predecessor trustee
hereunder under Section 11.01(a).

     Second: In case the principal of the Outstanding Securities of such series shall not
have become due and be unpaid, to the payment of interest on the Securities of such series,
in the chronological 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 rate borne by such Securities, such payments to be
made ratably to the Persons entitled thereto.

     Third: In case the principal of the Outstanding Securities of such series shall have
become due, by declaration or otherwise, to the payment of the whole amount then owing and
unpaid upon the Securities of such series for principal and premium, if any, and interest,
with interest on the overdue principal and premium, if any, and (to the extent that

41

 

such
interest has been collected by the Trustee) upon overdue installments of interest at the
rate borne by the Securities of such series, and in case such moneys shall be insufficient
to pay in full the whole amounts so due and unpaid upon the Securities of such series, then
to the payment of such principal and premium, if any, and interest without preference or
priority of principal and premium, if any, over interest, or of interest over principal and
premium, if any, 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 premium, if any, and accrued and unpaid interest.

Any surplus then remaining shall be paid to the Company or as directed by a court of competent
jurisdiction.

     Section 7.06 Control by Securityholders; Waiver of Past Defaults. The Holders of a majority in
principal amount of the Securities of any series at the time Outstanding may direct the time,
method and place of conducting any proceeding for any remedy available to the Trustee hereunder, or
of exercising any trust or power hereby conferred upon the Trustee with respect to the Securities
of such series, provided, however, that, subject to the provisions of Sections 11.01 and 11.02, the
Trustee shall have the right to decline to follow any
such direction if the Trustee being advised by counsel determines that the action so directed may
not lawfully be taken or would be unduly prejudicial to Holders not joining in such direction or
would involve the Trustee in personal liability. Prior to any declaration accelerating the
Maturity of the Securities of any series, the Holders of a majority in aggregate principal amount
of such series of Securities at the time Outstanding may on behalf of the Holders of all of the
Securities of such series waive any past Default or Event of Default hereunder and its consequences
except a Default in the payment of interest or any premium on or the principal of the Securities of
such series. Upon any such waiver the Company, the Trustee and the Holders of the Securities of
such series shall be restored to their former positions and rights hereunder, respectively; but no
such waiver shall extend to any subsequent or other Default or Event of Default or impair any right
consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as
permitted by this Section 7.06, said Default or Event of Default shall for all purposes of the
Securities of such series and this Indenture be deemed to have been cured and to be not continuing.

     Section 7.07 Limitation on Suits. No Holder of any Security of any series shall have any right to
institute any action, suit or proceeding at law or in equity for the execution of any trust
hereunder or for the appointment of a receiver or for any other remedy hereunder, in each case with
respect to an Event of Default with respect to such series of Securities, unless such Holder
previously shall have given to the Trustee written notice of one or more of the Events of Default
herein specified with respect to such series of Securities, and unless also the Holders of 25% in
principal amount of the Securities of such series then Outstanding shall have requested the Trustee
in writing to take action in respect of the matter complained of, and unless also there shall have
been offered to the Trustee security and indemnity satisfactory to it against the costs, expenses
and liabilities to be incurred therein or thereby, and the Trustee, for 60 days after receipt of
such notification, request and offer of indemnity, shall have neglected or refused to institute any
such action, suit or proceeding; and such notification, request and offer of indemnity

42

 

are hereby
declared in every such case to be conditions precedent to any such action, suit or proceeding by
any Holder of any Security of such series; it being understood and intended that no one or more of
the Holders of Securities of such series shall have any right in any manner whatsoever by his, her,
its or their action to enforce any right hereunder, except in the manner herein provided, and that
every action, suit or proceeding at law or in equity shall be instituted, had and maintained in the
manner herein provided and for the equal benefit of all Holders of the Outstanding Securities of
such series; provided, however, that nothing in this Indenture or in the Securities of such series
shall affect or impair the obligation of the Company, which is absolute and unconditional, to pay
the principal of, premium, if any, and interest on the Securities of such series to the respective
Holders of such Securities at the respective due dates in such Securities stated, or affect or
impair the right, which is also absolute and unconditional, of such Holders to institute suit to
enforce the payment thereof.

     Section 7.08 Undertaking for Costs. All parties to this Indenture and each Holder of any Security, by
such Holder’s acceptance thereof, shall be deemed to have agreed that any court may in its
discretion require, in any action,
suit or proceeding for the enforcement of any right or remedy under this Indenture, or in any
action, suit or proceeding against the Trustee for any action taken or omitted by it as Trustee,
the filing by any party litigant in such action, suit or proceeding of an undertaking to pay the
costs of such action, suit or proceeding, and that such court may in its discretion assess
reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in
such action, suit or proceeding, having due regard to the merits and good faith of the claims or
defenses made by such party litigant; provided, however, that the provisions of this Section 7.08
shall not apply to any action, suit or proceeding instituted by the Trustee, to any action, suit or
proceeding instituted by any one or more Holders of Securities holding in the aggregate more than
10% in principal amount of the Securities of any series Outstanding, or to any action, suit or
proceeding instituted by any Holder of Securities of any series for the enforcement of the payment
of the principal of or premium, if any, or the interest on, any of the Securities of such series,
on or after the respective due dates expressed in such Securities.

     Section 7.09 Remedies Cumulative. No remedy herein conferred upon or reserved to the Trustee or to the
Holders of Securities of any series is intended to be exclusive of any other remedy or remedies,
and each and every remedy shall be cumulative and shall be in addition to every other remedy given
hereunder or now or hereafter existing at law or in equity or by statute. No delay or omission of
the Trustee or of any Holder of the Securities of any series to exercise any right or power
accruing upon any Default or Event of Default shall impair any such right or power or shall be
construed to be a waiver of any such Default or Event of Default or an acquiescence therein; and
every power and remedy given by this Article VII to the Trustee and to the Holders of Securities of
any series, respectively, may be exercised from time to time and as often as may be deemed
expedient by the Trustee or by the Holders of Securities of such series, as the case may be. In
case the Trustee or any Holder of Securities of any series shall have proceeded to enforce any
right under this Indenture and the proceedings for the enforcement thereof shall have been
discontinued or abandoned because of waiver or for any other reason or shall have been adjudicated
adversely to the Trustee or to such Holder of Securities, then and in every such case the Company,
the Trustee and the Holders of the Securities of such series shall severally and respectively be
restored to their former positions and rights hereunder, and

43

 

thereafter all rights, remedies and
powers of the Trustee and the Holders of the Securities of such series shall continue as though no
such proceedings had been taken, except as to any matters so waived or adjudicated.

ARTICLE VIII

CONCERNING THE SECURITYHOLDERS

     Section 8.01 Evidence of Action of Securityholders. Whenever in this Indenture it is provided that the
Holders of a specified percentage or a majority in aggregate principal amount of the Securities or
of any series of Securities may take any action (including the making of any demand or request, the
giving of any notice, consent or waiver or the taking of any other action), the fact that at the
time of taking any such action the Holders of such specified percentage or majority have joined
therein may be evidenced by (a)
any instrument or any number of instruments of similar tenor executed by Securityholders in person,
by an agent or by a proxy appointed in writing, including through an electronic system for
tabulating consents operated by the Depositary for such series or otherwise (such action becoming
effective, except as herein otherwise expressly provided, when such instruments or evidence of
electronic consents are delivered to the Trustee and, where it is hereby expressly required, to the
Company), or (b) by the record of the Holders of Securities voting in favor thereof at any meeting
of Securityholders duly called and held in accordance with the provisions of Article IX, or (c) by
a combination of such instrument or instruments and any such record of such a meeting of
Securityholders.

     Section 8.02 Proof of Execution or Holding of Securities. Proof of the execution of any instrument by a
Securityholder or his, her or its agent or proxy and proof of the holding by any Person of any of
the Securities shall be sufficient if made in the following manner:

               (a) The fact and date of the execution by any Person of any such instrument may be proved (i)
by the certificate of any notary public or other officer in any jurisdiction who, by the laws
thereof, has power to take acknowledgments or proof of deeds to be recorded within such
jurisdiction, that the Person who signed such instrument did acknowledge before such notary public
or other officer the execution thereof, or (ii) by the affidavit of a witness of such execution
sworn to before any such notary or other officer. Where such execution is by a Person acting in
other than his or her individual capacity, such certificate or affidavit shall also constitute
sufficient proof of his or her authority.

               (b) The ownership of Securities of any series shall be proved by the Register of such
Securities or by a certificate of the Registrar for such series.

               (c) The record of any Holders’ meeting shall be proved in the manner provided in Section 9.06.

               (d) The Trustee may require such additional proof of any matter referred to in this Section
8.02 as it shall deem appropriate or necessary, so long as the request is a reasonable one.

44

 

               (e) If the Company shall solicit from the Holders of Securities of any series any action, the
Company may, at its option fix in advance a record date for the determination of Holders of
Securities entitled to take such action, but the Company shall have no obligation to do so. Any
such record date shall be fixed at the Company’s discretion. If such a record date is fixed, such
action may be sought or given before or after the record date, but only the Holders of Securities
of record at the close of business on such record date shall be deemed to be Holders of Securities
for the purpose of determining whether Holders of the requisite proportion of Outstanding
Securities of such series have authorized or agreed or consented to such action, and for that
purpose the Outstanding Securities of such series shall be computed as of such record date.

     Section 8.03 Persons Deemed Owners.

               (a) The Company, the Trustee and any agent of the Company or the Trustee may treat the Person
in whose name any Security is registered as the owner of such Security for the purpose of receiving
payment of principal of and premium, if any, and (subject to Section 3.08) interest, if any, on,
such Security and for all other purposes whatsoever, whether or not such Security be overdue, and
neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by
notice to the contrary. All payments made to any Holder, or upon his, her or its order, shall be
valid, and, to the extent of the sum or sums paid, effectual to satisfy and discharge the liability
for moneys payable upon such Security.

               (b) None of the Company, the Trustee, any Paying Agent or the Registrar will have any
responsibility or liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests in a Global Security or for maintaining, supervising or reviewing
any records relating to such beneficial ownership interests.

     Section 8.04 Effect of Consents. After an amendment, supplement, waiver or other action becomes
effective as to any series of Securities, a consent to it by a Holder of such series of Securities
is a continuing consent conclusive and binding upon such Holder and every subsequent Holder of the
same Securities or portion thereof, and of any Security issued upon the transfer thereof or in
exchange therefor or in place thereof, even if notation of the consent is not made on any such
Security. An amendment, supplement or waiver becomes effective in accordance with its terms and
thereafter binds every Holder.

     Section 9.02 Call of Meetings by Trustee. The Trustee may at any time call a meeting of all
Securityholders of all series that may be affected by the action proposed to be taken, to take any
action specified in Section 9.01, to be held at such time and at such place as the Trustee shall
determine. Notice of every meeting of the Securityholders of a series, setting forth the time and
the place of such meeting and in general terms the action proposed to be taken at such meeting,
shall be mailed to Holders of Securities of such series at their addresses as they shall appear on
the Register of the Company. Such notice shall be mailed not less than 20 nor more than 90 days
prior to the date fixed for the meeting.

     Section 9.03 Call of Meetings by Company or Securityholders. In case at any time the Company or the
Holders of at least 10% in aggregate principal amount of the Securities of a series (or of all
series, as the case may be) then Outstanding that may be affected by the action proposed to be
taken, shall have requested the Trustee to call a meeting of Securityholders of such series (or of
all series), by written request setting forth in reasonable detail the action proposed to be taken
at the meeting, and the Trustee shall not have mailed the notice of such meeting within 20 days
after receipt of such request, then the Company or such Securityholders may determine the time and

by mailing notice thereof as provided in Section 9.02.

     Section 9.04 Qualifications for Voting. To be entitled to vote at any meeting of Securityholders, a

and any representatives of the Trustee and its counsel and any representatives of the Company and
its counsel.

     Section 9.05 Regulation of Meetings.

               (a) Notwithstanding any other provisions of this Indenture, the Trustee may make such

proof of the holding of Securities and of the appointment of proxies, and in regard to the
appointment and duties of inspectors of votes, the submission and examination of proxies,
certificates and other evidence of the right to vote, and such other matters concerning the conduct
of the meeting as it shall deem fit.

46

 

               (b) The Trustee shall, by an instrument in writing, appoint a temporary chairman of the
meeting, unless the meeting shall have been called by the Company or by Securityholders as provided
in Section 9.03, in which case the Company or the Securityholders
calling the meeting, as the case may be, shall in like manner appoint a temporary chair. A
permanent chairman and a permanent secretary of the meeting shall be elected by majority vote of
the meeting.

               (c) At any meeting of Securityholders of a series, each Securityholder of such series of such
Securityholder’s proxy shall be entitled to one vote for each $1,000 principal amount of Securities
of such series Outstanding held or represented by him; provided, however, that no vote shall be
cast or counted at any meeting in respect of any Security challenged as not Outstanding and ruled
by the chairman of the meeting to be not Outstanding. The chairman of the meeting shall have no
right to vote other than by virtue of Securities of such series held by him or her or instruments
in writing as aforesaid duly designating him or her as the Person to vote on behalf of other
Securityholders. At any meeting of the Securityholders duly called pursuant to the provisions of
Section 9.02 or 9.03 the presence of Persons holding or representing Securities in an aggregate
principal amount sufficient to take action upon the business for the transaction of which such
meeting was called shall be necessary to constitute a quorum, and any such meeting may be adjourned
from time to time by a majority of those present, whether or not constituting a quorum, and the
meeting may be held as so adjourned without further notice.

     Section 9.06 Voting. The vote upon any resolution submitted to any meeting of Securityholders of a
series shall be by written ballots on which shall be subscribed the signatures of the Holders of
Securities of such series or of their representatives by proxy and the principal amounts of the
Securities of such series held or represented by them. The permanent chairman of the meeting shall
appoint two inspectors of votes who shall count all votes cast at the meeting for or against any
resolution and who shall make and file with the secretary of the meeting their verified written
reports in duplicate of all votes cast at the meeting. A record in duplicate of the proceedings of
each meeting of Securityholders shall be prepared by the secretary of the meeting and there shall
be attached to said record the original reports of the inspectors of votes on any vote by ballot
taken thereat and affidavits by one or more Persons having knowledge of the facts setting forth a
copy of the notice of the meeting and showing that said notice was mailed as provided in Section
9.02. The record shall show the principal amounts of the Securities voting in favor of or against
any resolution. The record shall be signed and verified by the affidavits of the permanent
chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company
and the other to the Trustee to be preserved by the Trustee.

          Any record so signed and verified shall be conclusive evidence of the matters therein stated.

     Section 9.07 No Delay of Rights by Meeting. Nothing contained in this Article IX shall be deemed or
construed to authorize or permit, by reason of any call of a meeting of Securityholders of any
series or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or
delay in the exercise of any
right or rights conferred upon or reserved

47

 

to the Trustee or to the Securityholders of such series
under any of the provisions of this Indenture or of the Securities of such series.

copies of the annual reports and of the information, documents and other reports (or
copies of such portions of any of the foregoing as the SEC may from time to time by
rules and regulations prescribe) which the Company may be required to file with the
SEC pursuant to Section 13 or Section 15(d) of the Exchange Act; or, if the Company

Section 10.02 so long as such entity is an obligor or guarantor on the Securities; and provided
further that the reports of such entity will not be required to include condensed consolidating
financial information for the Company in a footnote to the financial statements of such entity.

               (b) Delivery of such reports, information and documents to the Trustee is for informational

rely conclusively and exclusively on Officer’s Certificates).

               (c) Any document referred to in this Section 10.02 that is filed with the SEC via the SEC’s
Electronic Data Gathering, Analysis and Retrieval System (EDGAR) and publicly available without

ARTICLE XI

CONCERNING THE TRUSTEE

     Section 11.01 Rights of Trustees; Compensation and Indemnity. The Trustee accepts the
trusts created by this Indenture upon the terms and conditions hereof, including the following, to
all of which the parties hereto and the Holders from time to time of the Securities agree:

49

 

               (a) The Trustee shall be entitled to such compensation as the Company and the Trustee shall
from time to time agree in writing for all services rendered by it hereunder (including in any
agent capacity in which it acts). The compensation of the Trustee shall not be limited by any
provision of law in regard to the compensation of a trustee of an express trust. The Company shall
reimburse the Trustee promptly upon its request for all reasonable out-of-pocket expenses,
disbursements and advances incurred or made by the Trustee (including the reasonable expenses and
disbursements of its agents and counsel), except any such expense, disbursement or advance as may
be attributable to its own negligence, bad faith or willful misconduct.

     The Company also agrees to indemnify each of the Trustee and any predecessor Trustee hereunder
for, and to hold it harmless against, any and all loss, liability, damage, claim, or expense
incurred without its own negligence or willful misconduct, arising out of or in connection with the
acceptance or administration of the trust or trusts hereunder and the performance of its duties
(including in any agent capacity in which it acts), as well as the costs and expenses of defending
itself against any claim (whether asserted by the Company, a Holder or any other Person) or
liability in connection with the exercise or performance of any of its powers or duties hereunder,
except those attributable to its negligence or willful misconduct. The Trustee shall notify the
Company promptly of any claim for which it may seek indemnity. The Company shall defend the claim
and the Trustee shall cooperate in the defense. The Trustee may have one separate counsel of its
selection and the Company shall pay the reasonable fees and expenses of such counsel. The Company
need not pay for any settlement made without its consent, which consent shall not be unreasonably
withheld.

     As security for the performance of the obligations of the Company under this Section 11.01(a),
the Trustee shall have a lien upon all property and funds held or collected by the Trustee as such,
except funds held in trust by the Trustee to pay principal of and interest on any Securities.
Notwithstanding any provisions of this Indenture to the contrary, the obligations of the Company to
compensate and indemnify the Trustee under this Section 11.01(a) shall survive the resignation or
removal of the Trustee, the termination of this Indenture and any satisfaction and discharge under
Article XII. When the Trustee incurs expenses or renders services after an Event of Default
specified in clause (e) or (f) of Section 7.01 occurs, the expenses and compensation for the
services are intended to constitute expenses of administration under any applicable federal or
state bankruptcy, insolvency or similar laws.

               (b) The Trustee may execute any of the trusts or powers hereof and perform any duty hereunder
either directly or by its agents and attorneys and shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it hereunder.

               (c) The Trustee shall not be responsible in any manner whatsoever for the correctness of the
recitals herein or in the Securities (except its certificates of authentication thereon) contained,
all of which are made solely by the Company; and the Trustee shall not be responsible or
accountable in any manner whatsoever for or with respect to the validity or execution or
sufficiency of this Indenture or of the Securities (except its certificates of authentication
thereon), and the Trustee makes no representation with respect thereto, except that

50

 

the Trustee represents that it is duly authorized to execute and deliver this Indenture,
authenticate the Securities and perform its obligations hereunder and that the statements made by
it in a Statement of Eligibility on Form T-1 supplied to the Company are true and accurate, subject
to the qualifications set forth therein. The Trustee shall not be accountable for the use or
application by the Company of any Securities, or the proceeds of any Securities, authenticated and
delivered by the Trustee in conformity with the provisions of this Indenture.

               (d) The Trustee may consult with counsel of its selection, and, to the extent permitted by
Section 11.02, any Opinion of Counsel shall be full and complete authorization and protection in
respect of any action taken or suffered by the Trustee hereunder in good faith and in accordance
with such Opinion of Counsel.

               (e) The Trustee, to the extent permitted by Section 11.02, may rely upon the certificate of
the Secretary or one of the Assistant Secretaries of the Company as to the adoption of any Board
Resolution or resolution of the stockholders of the Company, and any request, direction, order or
demand of the Company mentioned herein shall be sufficiently evidenced by, and 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 shall receive
and conclusively rely upon, an Officer’s Certificate of the Company and an Opinion of Counsel
(unless other evidence in respect thereof be herein specifically prescribed).

               (f) Subject to Section 11.04, the Trustee or any agent of the Trustee, in its individual or
any other capacity, may become the owner or pledgee of Securities and, subject to Sections 310(b)
and 311 of the Trust Indenture Act, may otherwise deal with the Company with the same rights it
would have had if it were not the Trustee or such agent.

               (g) Money held by the Trustee in trust hereunder need not be segregated from other funds
except to the extent required by law. The Trustee shall be under no liability for interest on any
money received by it hereunder except as otherwise agreed in writing with the Company.

               (h) Any action taken by the Trustee pursuant to any provision hereof at the request or with
the consent of any Person who at the time is the Holder of any Security shall be conclusive and
binding in respect of such Security upon all future Holders thereof or of any Security or
Securities which may be issued for or in lieu thereof in whole or in part, whether or not such
Security shall have noted thereon the fact that such request or consent had been made or given.

               (i) Subject to the provisions of Section 11.02, the Trustee may conclusively rely and shall be
protected in acting or refraining from acting upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, bond, debenture or other
paper or document believed by it to be genuine and to have been signed or presented by the proper
party or parties.

               (j) Subject to the provisions of Section 11.02, the Trustee shall not be under any obligation
to exercise any of the rights or powers vested in it by this Indenture at the request, order or
direction of any of the Holders of the Securities, pursuant to any provision of

51

 

this Indenture, unless one or more of the Holders of the Securities shall have offered to the
Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities which
may be incurred by it therein or thereby.

               (k) Subject to the provisions of Section 11.02, 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 its discretion
or within the rights or powers conferred upon it by this Indenture.

               (l) Subject to the provisions of Section 11.02, the Trustee shall not be deemed to have
knowledge or notice of any Default or Event of Default unless a Responsible Officer of the Trustee
has actual knowledge thereof or unless the Holders of not less than 25% of the Outstanding
Securities notify the Trustee thereof.

               (m) Subject to the provisions of the first paragraph of Section 11.02, 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, may,
but shall not be required to, make further inquiry or investigation into such facts or matters as
it may see fit.

               (n) 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.

               (o) In no event shall the Trustee be responsible or liable for special, indirect, punitive or
consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit)
irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and
regardless of the form of action.

               (p) The Trustee shall not be required to give any bond or surety in respect of the performance
of its powers and duties hereunder.

               (q) The Trustee may request that the Company deliver a certificate setting forth the names of
individuals and/or titles of officers authorized at such time to take specified actions pursuant to
this Indenture.

          Section 11.02 Duties of Trustee.

               (a) If one or more of the Events of Default specified in Section 7.01 with respect to the
Securities of any series shall have happened, then, during the continuance thereof, the Trustee
shall, with respect to such Securities, exercise such of the rights and powers vested in it by this
Indenture, and shall 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 such person’s own affairs.

52

 

               (b) None of the provisions of this Indenture shall be construed as relieving the Trustee from
liability for its own negligent action, negligent failure to act, or its own willful misconduct,
except that, anything in this Indenture contained to the contrary notwithstanding,

               (i) unless and until an Event of Default specified in Section 7.01 with respect
to the Securities of any series shall have happened which at the time is continuing,

                    (A) the Trustee undertakes to perform such duties and only such
duties with respect to the Securities of that series as are
specifically set out in this Indenture, and no implied covenants or
obligations shall be read into this Indenture against the Trustee,
whose duties and obligations shall be determined solely by the
express provisions of this Indenture; and

                    (B) the Trustee may conclusively rely, as to the truth of the
statements and the correctness of the opinions expressed therein, in
the absence of bad faith on the part of the Trustee, upon
certificates and opinions furnished to it pursuant to the express
provisions of this Indenture; but in the case of any such
certificates or opinions which, by the provisions of this Indenture,
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, statements, opinions or conclusions
stated therein);

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

               (iii) the Trustee shall not be liable to any Holder of Securities or to any
other Person with respect to any action taken or omitted to be taken by it in good
faith, in accordance with the direction of Securityholders given as provided in
Section 7.06, relating to the time, method and place of conducting any proceeding
for any remedy available to it or exercising any trust or power conferred upon it by
this Indenture.

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

53

 

               (d) 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 11.02.

     Section 11.03 Notice of Defaults. Within 90 days after the occurrence thereof, and if known to
the Trustee, the Trustee shall give to the Holders of the Securities of a series notice of each
Default or Event of Default with respect to the Securities of such series known to the Trustee, by
transmitting such notice to Holders at their addresses as the same shall then appear on the
Register of the Company, unless such Default shall have been cured or waived before the giving of
such notice (the term “Default” being hereby defined to be the events specified in Section 7.01,
which are, or after notice or lapse of time or both would become, Events of Default as defined in
said Section). Except in the case of a Default or Event of Default in payment of the principal of,
premium, if any, or interest on any of the Securities of such series when and as the same shall
become payable, or to make any sinking fund payment as to Securities of the same series, the
Trustee shall be protected in withholding such notice, if and so long as a Responsible Officer or
Responsible Officers of the Trustee in good faith determines that the withholding of such notice is
in the interests of the Holders of the Securities of such series.

     Section 11.04 Eligibility; Disqualification.

               (a) The Trustee shall at all times satisfy the requirements of TIA Section 310(a). The
Trustee shall have a combined capital and surplus of at least $50 million as set forth in its most
recent published annual report of condition, and shall have a Corporate Trust Office. If at any
time the Trustee shall cease to be eligible in accordance with the provisions of this Section
11.04, it shall resign immediately in the manner and with the effect hereinafter specified in this
Article.

               (b) The Trustee shall comply with TIA Section 310(b); provided, however, that there shall be
excluded from the operation of TIA Section 310(b)(i) any indenture or indentures under which other
securities or certificates of interest or participation in other securities of the Company are
outstanding if the requirements for such exclusion set forth in TIA Section 310(b)(i) are met. If
the Trustee has or shall acquire a conflicting interest within the meaning of Section 310(b) of the
Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and
in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this
Indenture. If Section 310(b) of the Trust Indenture Act is amended any time after the date of this
Indenture to change the circumstances under which a Trustee shall be deemed to have a conflicting
interest with respect to the Securities of any series or to change any of the definitions in
connection therewith, this Section 11.04 shall be automatically amended to incorporate such
changes.

     Section 11.05 Resignation and Notice; Removal. The Trustee, or any successor to it hereafter
appointed, may at any time resign and be discharged of the trusts hereby created with respect to
any one or more or all series of Securities by giving to the Company notice in writing. Such
resignation shall take effect upon the appointment of a successor Trustee and the acceptance of
such appointment by such successor Trustee. Any Trustee hereunder may be removed with respect to
any series of Securities at any time by the filing with such Trustee and

54

 

the
delivery to the Company of an instrument or instruments in writing signed by the Holders of a majority in
principal amount of the Securities of such series then Outstanding, specifying such removal and the
date when it shall become effective.

          If at any time:

          (1) the Trustee shall fail to comply with the provisions of TIA Section 310(b) after written
request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for
at least six months (or, if it is a shorter period, the period since the initial issuance of the
Securities of such series), or

          (2) the Trustee shall cease to be eligible under Section 11.04 and shall fail to resign after
written request therefor by the Company or by any Holder who has been a bona fide Holder of a
Security for at least six months (or, if it is a shorter period, the period since the initial
issuance of the Securities of such series), or

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

then, in any such case, (i) the Company by written notice to the Trustee may remove the Trustee and
appoint a successor Trustee with respect to all Securities, or (ii) subject to TIA Section 315(e),
any Securityholder who has been a bona fide Holder of a Security for at least six months (or, if it
is a shorter period, the period since the initial issuance of the Securities of such series) may,
on behalf of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a
successor Trustee or Trustees.

          Upon its resignation or removal, any Trustee shall be entitled to the payment of reasonable
compensation for the services rendered hereunder by such Trustee and to the payment of all
reasonable expenses incurred hereunder and all moneys then due to it hereunder. The Trustee’s
rights to indemnification provided in Section 11.01(a) shall survive its resignation or removal.

     Section 11.06 Successor Trustee by Appointment.

               (a) In case at any time the Trustee shall resign, or shall be removed (unless the Trustee
shall be removed as provided in Section 11.04(b), in which event the vacancy shall be filled as
provided in said subdivision), or shall become incapable of acting, or shall be adjudged bankrupt
or insolvent, or if a receiver of the Trustee or of its property shall be appointed, or if 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 with respect to the Securities of one or
more series, a successor Trustee with respect to the Securities of that or those series (it being
understood that any such successor Trustee may be appointed with respect to the Securities of one
or more or all of such series and that at any time there shall be only one Trustee with respect to
the Securities of any series) may be appointed by the Holders of a majority in principal

55

 

amount of the Securities of that or those series then Outstanding, by an instrument or
instruments in writing signed in duplicate by such Holders and filed, one original thereof with the
Company and the other with the successor Trustee; but, until a successor Trustee shall have been so
appointed by the Holders of Securities of that or those series as herein authorized, the Company,
or, in case all or substantially all the assets of the Company shall be in the possession of one or
more custodians or receivers lawfully appointed, or of trustees in bankruptcy or reorganization
proceedings (including a trustee or trustees appointed under the provisions of the federal
bankruptcy laws, as now or hereafter constituted), or of assignees for the benefit of creditors,
such receivers, custodians, trustees or assignees, as the case may be, by an instrument in writing,
shall appoint a successor Trustee with respect to the Securities of such series. Subject to the
provisions of Sections 11.04 and 11.05, upon the appointment as aforesaid of a successor Trustee
with respect to the Securities of any series, the Trustee with respect to the Securities of such
series shall cease to be Trustee hereunder. After any such appointment other than by the Holders
of Securities of that or those series, the Person making such appointment shall forthwith cause
notice thereof to be mailed to the Holders of Securities of such series at their addresses as the
same shall then appear on the Register of the Company but any successor Trustee with respect to the
Securities of such series so appointed shall, immediately and without further act, be superseded by
a successor Trustee appointed by the Holders of Securities of such series in the manner above
prescribed, if such appointment be made prior to the expiration of one year from the date of the
mailing of such notice by the Company, or by such receivers, trustees or assignees.

               (b) If any Trustee with respect to the Securities of one or more series shall resign or be
removed and a successor Trustee shall not have been appointed by the Company or by the Holders of
the Securities of such series or, if any successor Trustee so appointed shall not have accepted its
appointment within 30 days after such appointment shall have been made, the resigning Trustee at
the expense of the Company may apply to any court of competent jurisdiction for the appointment of
a successor Trustee. If in any other case a successor Trustee shall not be appointed pursuant to
the foregoing provisions of this Section 11.06 within three months after such appointment might
have been made hereunder, the Holder of any Security of the applicable series or any retiring
Trustee at the expense of the Company may apply to any court of competent jurisdiction to appoint a
successor Trustee. Such court may thereupon, in any such case, after such notice, if any, as such
court may deem proper and prescribe, appoint a successor Trustee.

               (c) Any successor Trustee appointed hereunder with respect to the Securities of one or more
series shall execute, acknowledge and deliver to its predecessor Trustee and to the Company, or to
the receivers, trustees, assignees or court appointing it, as the case may be, an instrument
accepting such appointment hereunder, and thereupon such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the authority, rights, powers, trusts,
immunities, duties and obligations with respect to such series of such predecessor Trustee with
like effect as if originally named as Trustee hereunder, and such predecessor Trustee, upon payment
of its charges and disbursements then unpaid, shall thereupon become obligated to pay over, and
such successor Trustee shall be entitled to receive, all moneys and properties held by such
predecessor Trustee as Trustee hereunder, subject nevertheless to its lien provided for in Section
11.01(a). Nevertheless, on the written request of the Company or of the successor Trustee or of
the Holders of at least 10% in principal amount of the Securities of

56

 

such series then Outstanding, such predecessor Trustee, upon payment of its said charges and
disbursements, shall execute and deliver an instrument transferring to such successor Trustee upon
the trusts herein expressed all the rights, powers and trusts of such predecessor Trustee and shall
assign, transfer and deliver to the successor Trustee all moneys and properties held by such
predecessor Trustee, subject nevertheless to its lien provided for in Section 11.01(a); and, upon
request of any such successor Trustee and the Company shall make, execute, acknowledge and deliver
any and all instruments in writing for more fully and effectually vesting in and confirming to such
successor Trustee all such authority, rights, powers, trusts, immunities, duties and obligations.

     Section 11.07 Successor Trustee by Merger. Any Person into which the Trustee or any successor to
it in the trusts created by this Indenture shall be merged or converted, or any Person with which
it or any successor to it shall be consolidated, or any Person resulting from any merger,
conversion or consolidation to which the Trustee or any such successor to it shall be a party, or
any Person to which the Trustee or any successor to it shall sell or otherwise transfer all or
substantially all of the corporate trust business of the Trustee, shall be the successor Trustee
under this Indenture without the execution or filing of any paper or any further act on the part of
any of the parties hereto; provided that such Person shall be otherwise qualified and eligible
under this Article. In case at the time such successor to the Trustee shall succeed to the trusts
created by this Indenture with respect to one or more series of Securities, any of such Securities
shall have been authenticated but not delivered by the Trustee then in office, any successor to
such Trustee may adopt the certificate of authentication of any predecessor Trustee, and deliver
such Securities so authenticated; and in case at that time any of the Securities 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 certificates shall have the full force which it is anywhere in the Securities or in this
Indenture provided that the certificate of the Trustee shall have; provided, however, that the
right to adopt the certificate of authentication of any predecessor Trustee or authenticate
Securities in the name of any predecessor Trustee shall apply only to its successor or successors
by merger, conversion or consolidation.

     Section 11.08 Right to Rely on Officer’s Certificate. Subject to Section 11.02, and subject to
the provisions of Section 16.01 with respect to the certificates required thereby, whenever in the
administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable
that a matter be proved or established prior to taking or suffering any action hereunder, such
matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the
absence of negligence or willful misconduct on the part of the Trustee, be deemed to be
conclusively proved and established by an Officer’s Certificate and Opinion of Counsel with respect
thereto delivered to the Trustee, and such Officer’s Certificate and Opinion of Counsel, in the
absence of negligence, bad faith or willful misconduct on the part of the Trustee, shall be full
warrant to the Trustee for any action taken, suffered or omitted by it under the provisions of this
Indenture upon the faith thereof.

     Section 11.09 Appointment of Authenticating Agent. The Trustee may appoint an agent (the
“Authenticating Agent”) reasonably acceptable to the Company to authenticate the Securities, and
the Trustee shall give written notice of such appointment to all Holders of

57

 

Securities of the series with respect to which such Authenticating Agent will serve. Unless
limited by the terms of such appointment, any such Authenticating Agent may authenticate Securities
whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee
includes authentication by the Authenticating Agent. Securities so authenticated shall be entitled
to the benefits of this Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder.

          Each Authenticating Agent shall at all times be a corporation organized and doing business and
in good standing under the laws of the United States, any State thereof or the District of
Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and
surplus of not less than $50,000,000 and subject to supervision or examination by federal or state
authority. If such corporation publishes reports of condition at least annually, pursuant to law or
to the requirements of said supervising or examining authority, then for the purposes of this
Article XI, the combined capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so published. If at any
time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this
Article XI, it shall resign immediately in the manner and with the effect specified in this Article
XI.

          Any corporation into which an Authenticating Agent may be merged or converted or with which it
may be consolidated, or any corporation resulting from any merger, conversion or consolidation to
which such Authenticating Agent shall be a party, or any corporation succeeding to all or
substantially all the corporate agency or corporate trust business of an Authenticating Agent,
shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible
under this Article XI, without the execution or filing of any paper or any further act on the part
of the Trustee or the Authenticating Agent.

          An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee
and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by
giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such
a notice of resignation or upon such a termination, or in case at any time such Authenticating
Agent shall cease to be eligible in accordance with the provisions of this Section 11.09, the
Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and
shall give written notice of such appointment to all Holders of Securities of the series with
respect to which such Authenticating Agent will serve. Any successor Authenticating Agent upon
acceptance of its appointment hereunder shall become vested with all the rights, powers and duties
of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the provisions of this
Section 11.09.

          The Company agrees to pay to each Authenticating Agent from time to time reasonable
compensation for its services under this Section 11.09.

     Section 11.10 Communications by Securityholders with Other Securityholders. Holders of Securities
may communicate pursuant to Section 312(b) of the Trust Indenture Act with other Holders with
respect to their rights under this Indenture or the Securities. The Company, the

58

 

Trustee, the Registrar and anyone else shall have the protection of Section 312(c) of the Trust
Indenture Act with respect to such communications.

ARTICLE XII

SATISFACTION AND DISCHARGE; DEFEASANCE

     Section 12.01 Applicability of Article. If, pursuant to Section 3.01, provision is made for the
defeasance of Securities of a series and if the Securities of such series are denominated and
payable only in U.S. Dollars (except as provided pursuant to Section 3.01), then the provisions of
this Article shall be applicable except as otherwise specified pursuant to Section 3.01 for
Securities of such series. Defeasance provisions, if any, for Securities denominated in a Foreign
Currency may be specified pursuant to Section 3.01.

     Section 12.02 Satisfaction and Discharge of Indenture. This Indenture, with respect to the
Securities of any series (if all series issued under this Indenture are not to be affected), shall,
upon Company Order, cease to be of further effect (except as to any surviving rights of
registration of transfer or exchange of such Securities herein expressly provided for and rights to
receive payments of principal of and premium, if any, and interest on such Securities) and the
Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction
and discharge of this Indenture, when,

               (a) either:

               (i) all Securities of such series theretofore authenticated and delivered
(other than (A) Securities that have been destroyed, lost or stolen and that have
been replaced or paid as provided in Section 3.07 and (B) Securities for whose
payment money has theretofore been deposited in trust or segregated and held in
trust by the Company and thereafter repaid to the Company or discharged from such
trust, as provided in Section 6.03) have been delivered to the Trustee for
cancellation; or

               (ii) all Securities of such series not theretofore delivered to the Trustee for
cancellation,

                    (A) have become due and payable, or

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

                    (C) are to be called for redemption within one year under
arrangements satisfactory to the Trustee for the giving of notice by
the Trustee in the name, and at the expense, of the Company, and the
Company,

and in the case of (A), (B) or (C) above, has deposited or caused to be deposited with the Trustee
or Paying Agent as trust funds in trust for the purpose an amount in the Currency in which such

59

 

Securities are denominated (except as otherwise provided pursuant to Section 3.01) sufficient to
pay and discharge the entire Indebtedness on such Securities for principal and premium, if any, and
interest to the date of such deposit (in the case of Securities that have become due and payable)
or to the Stated Maturity or Redemption Date, as the case may be; provided, however, in the event a
petition for relief under federal bankruptcy laws, as now or hereafter constituted, or any other
applicable federal or state bankruptcy, insolvency or other similar law, is filed with respect to
the Company within 91 days after the deposit and the Trustee is required to return the moneys then
on deposit with the Trustee to the Company, the obligations of the Company under this Indenture
with respect to such Securities shall not be deemed terminated or discharged;

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

               (c) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of
Counsel each stating that all conditions precedent herein provided for relating to the satisfaction
and discharge of this Indenture with respect to such series have been complied with.
Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to
the Trustee under Section 11.01 and, if money shall have been deposited with the Trustee pursuant
to subclause (B) of clause (a)(i) of this Section, the obligations of the Trustee under Section
12.07 and the last paragraph of Section 6.03(e) shall survive.

     Section 12.03 Defeasance upon Deposit of Moneys or U.S. Government Obligations. At the Company’s
option, either (a) the Company shall be deemed to have been Discharged (as defined below) from its
obligations with respect to Securities of any series on the first day after the applicable
conditions set forth below have been satisfied or (b) the Company shall cease to be under any
obligation to comply with any term, provision or condition set forth in Section 6.04, 6.07 and
Section 10.02 with respect to Securities of any series (and, if so specified pursuant to Section
3.01, any other restrictive covenant added for the benefit of such series pursuant to Section 3.01)
at any time after the applicable conditions set forth below have been satisfied (such action under
clauses (a) or (b) of this paragraph in no circumstance may be construed as an Event of Default
under Section 7.01):

          (a) The Company shall have deposited or caused to be deposited irrevocably with the Trustee as
trust funds in trust, specifically pledged as security for, and dedicated solely to, the benefit of
the Holders of the Securities of such series (i) money in an amount, or (ii) U.S. Government
Obligations (as defined below) that 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, money in an amount, or (iii) a combination of (i) and (ii), sufficient (as certified
by an independent financial professional) to pay and discharge each installment of principal
(including any mandatory sinking fund payments) of and premium, if any, and interest on, the
Outstanding Securities of such series on the dates such installments of interest or principal and
premium are due and before or after a deposit, the Company may make arrangements satisfactory to
the Trustee for the redemption of Securities at a future date in accordance with Article IV;

60

 

          (b) No Default with respect to the Securities of such series shall have occurred and be
continuing on the date of such deposit (other than a Default resulting from the borrowing of funds
and the grant of any related liens to be applied to such deposit); and

          (c) If (and only if) the Discharge described in Section 12.03(a) will occur more than one year
before Maturity, the Company shall have delivered to the Trustee an Opinion of Counsel to the
effect that Holders of the Securities of such series will not recognize income, gain or loss for
U.S. federal income tax purposes as a result of the Company’s exercise of its option under this
Section and will be subject to federal income tax on the same amounts and in the same manner and at
the same times as would have been the case if such action had not been exercised and, in the case
of the Securities of such series being Discharged accompanied by a ruling to that effect received
from or published by the Internal Revenue Service.

          “Discharged” means that the Company shall be deemed to have paid and discharged the entire
Indebtedness represented by, and obligations under, the Securities of such series and to have
satisfied all the obligations under this Indenture relating to the Securities of such series (and
the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the
same), except (A) the rights of Holders of Securities of such series to receive, from the trust
fund described in clause (a) above, payment of the principal of and premium, if any, and interest
on such Securities when such payments are due, (B) the Company’s obligations with respect to
Securities of such series under Sections 3.04, 3.06, 3.07, 6.02, 12.06 and 12.07 and (C) the
rights, powers, trusts, duties and immunities of the Trustee hereunder.

          “U.S. Government Obligations” means securities that are (i) direct obligations of the United
States for the payment of which its full faith and credit is pledged or (ii) obligations of a
Person controlled or supervised by and acting as an agency or instrumentality of the United States
the timely of payment of which is unconditionally guaranteed as a full faith and credit obligation
by the United States, that, in either case under clauses (i) or (ii) are not callable or redeemable
at the action of the issuer thereof, and shall also include a depositary receipt issued by a bank
or trust company as custodian with respect to any such U.S. Government Obligation or a specific
payment of interest on or principal of any such U.S. Government Obligation held by such custodian
for the account of the holder of a depositary receipt; provided that (except as required by law)
such custodian is not authorized to make any deduction from the amount payable to the holder of
such depositary receipt from any amount received by the custodian in respect of the U.S. Government
Obligation or the specific payment of interest on or principal of the U.S. Government Obligation
evidenced by such depositary receipt.

     Section 12.04 Repayment to Company. The Trustee and any Paying Agent shall promptly pay to the
Company (or to its designee) upon Company Order any excess moneys or U.S. Government Obligations
held by them at any time, including any such moneys or obligations held by the Trustee under any
escrow trust agreement entered into pursuant to Section 12.06. The provisions of the last
paragraph of Section 6.03 shall apply to any money held by the Trustee or any Paying Agent under
this Article that remains unclaimed for two years after the Maturity of any series of Securities
for which money or U.S. Government Obligations have been deposited pursuant to Section 12.03.

61

 

     Section 12.05 Indemnity for U.S. Government Obligations. The Company shall pay and shall
indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the
deposited U.S. Government Obligations or the principal or interest received on such U.S. Government
Obligations.

     Section 12.06 Deposits to Be Held in Escrow. Any deposits with the Trustee referred to in Section
12.03 above shall be irrevocable (except to the extent provided in Sections 12.04 and 12.07) and
shall be made under the terms of an escrow trust agreement. If any Outstanding Securities of a
series are to be redeemed prior to their Stated Maturity, whether pursuant to any optional
redemption provisions or in accordance with any mandatory or optional sinking fund requirement, the
applicable escrow trust agreement shall provide therefor and the Company shall make such
arrangements as are satisfactory to the Trustee for the giving of notice of redemption by the
Trustee in the name, and at the expense, of the Company. The agreement shall provide that, upon
satisfaction of any mandatory sinking fund payment requirements, whether by deposit of moneys,
application of proceeds of deposited U.S. Government Obligations or, if permitted, by delivery of
Securities, the Trustee shall pay or deliver over to the Company as excess moneys pursuant to
Section 12.04 all funds or obligations then held under the agreement and allocable to the sinking
fund payment requirements so satisfied.

          If Securities of a series with respect to which such deposits are made may be subject to later
redemption at the option of the Company or pursuant to optional sinking fund payments, the
applicable escrow trust agreement may, at the option of the Company, provide therefor. In the case
of an optional redemption in whole or in part, such agreement shall require the Company to deposit
with the Trustee on or before the date notice of redemption is given funds sufficient to pay the
Redemption Price of the Securities to be redeemed together with all unpaid interest thereon to the
Redemption Date. Upon such deposit of funds, the Trustee shall pay or deliver over to the Company
as excess funds pursuant to Section 12.04 all funds or obligations then held under such agreement
and allocable to the Securities to be redeemed. In the case of exercise of optional sinking fund
payment rights by the Company, such agreement shall, at the option of the Company, provide that
upon deposit by the Company with the Trustee of funds pursuant to such exercise the Trustee shall
pay or deliver over to the Company as excess funds pursuant to Section 12.04 all funds or
obligations then held under such agreement for such series and allocable to the Securities to be
redeemed.

     Section 12.07 Application of Trust Money.

          (a) Neither the Trustee nor any other Paying Agent shall be required to pay interest on any
moneys deposited pursuant to the provisions of this Indenture, except such as it shall agree with
the Company in writing to pay thereon. Any moneys so deposited for the payment of the principal
of, or premium, if any, or interest on the Securities of any series and remaining unclaimed for two
years after the date of the maturity of the Securities of such series or the date fixed for the
redemption of all the Securities of such series at the time outstanding, as the case may be, shall
be repaid by the Trustee or such other Paying Agent to the Company upon its written request and
thereafter, anything in this Indenture to the contrary notwithstanding, any rights of the Holders
of Securities of such series in respect of which such moneys shall have been

62

 

deposited shall be enforceable only against the Company, and all liability of the Trustee or
such other Paying Agent with respect to such moneys shall thereafter cease.

          (b) Subject to the provisions of the foregoing paragraph, any moneys which at any time shall
be deposited by the Company or on its behalf with the Trustee or any other Paying Agent for the
purpose of paying the principal of, premium, if any, and interest on any of the Securities shall be
and are hereby assigned, transferred and set over to the Trustee or such other Paying Agent in
trust for the respective Holders of the Securities for the purpose for which such moneys shall have
been deposited; but such moneys need not be segregated from other funds except to the extent
required by law.

     Section 12.08 Deposits of Non-U.S. Currencies. Notwithstanding the foregoing provisions of this
Article, if the Securities of any series are payable in a Currency other than U.S. Dollars, the
Currency or the nature of the government obligations to be deposited with the Trustee under the
foregoing provisions of this Article shall be as set forth in the Officer’s Certificate or
established in the supplemental indenture under which the Securities of such series are issued.

     Section 12.09 Reinstatement. If the Trustee or Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with this Article XII by reason of any legal proceeding or by
reason of any order or judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company’s obligations under this Indenture and the
applicable Securities shall be revived and reinstated as though no deposit had occurred pursuant to
this Article XII until such time as the Trustee or Paying Agent is permitted to apply all such
money or U.S. Government Obligations in accordance with this Article XII; provided, however, that,
if the Company has made any payment of interest on or principal of any Securities because of the
reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of
such Securities to receive such payment from the money or U.S. Government Obligations held by the
Trustee or Paying Agent.

ARTICLE XIII

IMMUNITY OF CERTAIN PERSONS

     Section 13.01 No Personal Liability. No recourse shall be had for the payment of the principal
of, or the premium, if any, or interest on, any Security or for any claim based thereon or
otherwise in respect thereof or of the Indebtedness represented thereby, or upon any obligation,
covenant or agreement of this Indenture, against any incorporator, stockholder, officer or
director, as such, past, present or future, of the Company or of any successor corporation, either
directly or through the Company or any successor corporation, whether by virtue of any
constitutional provision, statute or rule of law, or by the enforcement of any assessment or
penalty or otherwise; it being expressly agreed and understood that this Indenture and the
Securities are solely corporate obligations, and that no personal liability whatsoever shall attach
to, or be incurred by, any incorporator, stockholder, officer or director, as such, past, present
or future, of the Company or of any successor corporation, either directly or through the Company
or any successor corporation, because of the incurring of the Indebtedness hereby authorized or
under or by

63

 

reason of any of the obligations, covenants, promises or agreements contained in this Indenture or
in any of the Securities, or to be implied herefrom or therefrom, and that all liability, if any,
of that character against every such incorporator, stockholder, officer and director is, by the
acceptance of the Securities and as a condition of, and as part of the consideration for, the
execution of this Indenture and the issue of the Securities expressly waived and released.

issue, authentication or delivery of the Securities of any series, as herein set forth, or other
conditions, limitations or restrictions thereafter to be observed.

     Subject to the provisions of Section 14.03, the Trustee is authorized to join with the Company
in the execution of any such supplemental indenture, to make the further

65

 

agreements and stipulations which may be therein contained and to accept the conveyance,
transfer, assignment, mortgage or pledge of any property or assets thereunder.

          Any supplemental indenture authorized by the provisions of this Section 14.01 may be executed
by the Company and the Trustee without the consent of the Holders of any of the Securities at the
time Outstanding, notwithstanding any of the provisions of Section 14.02.

     Section 14.02 With Consent of Securityholders; Limitations.

          (a) With the consent of the Holders (evidenced as provided in Article VIII) of a majority in
aggregate principal amount of the Outstanding Securities of each series affected by such
supplemental indenture voting separately, the Company and the Trustee may, from time to time and at
any time, enter into an indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any provisions of this Indenture or of
modifying in any manner the rights of the Holders of the Securities of such series to be affected;
provided, however, that no such supplemental indenture shall, without the consent of the Holder of
each Outstanding Security of each such series affected thereby,

          (i) extend the Stated Maturity of the principal of, or any installment of
interest on, any Security, or reduce the principal amount thereof or the interest
thereon or any premium payable upon redemption thereof, or extend the Stated
Maturity of, or change the place of payment where, or the Currency in which the
principal of and premium, if any, or interest on such Security is denominated or
payable, or reduce the amount of the principal of an Original Issue Discount
Security that would be due and payable upon a declaration of acceleration of the
Maturity thereof pursuant to Section 7.02, or impair the right to institute suit for
the enforcement of any payment on or after the Stated Maturity thereof (or, in the
case of redemption, on or after the Redemption Date), or materially adversely affect
the economic terms of any right to convert or exchange any Security as may be
provided pursuant to Section 3.01; or

          (ii) reduce the percentage in principal amount of the Outstanding Securities of
any series, the consent of whose Holders is required for any supplemental indenture,
or the consent of whose Holders is required for any waiver of compliance with
certain provisions of this Indenture or certain Defaults hereunder and their
consequences provided for in this Indenture; or

          (iii) modify any of the provisions of this Section, Section 7.06 or Section
6.06, except to increase any such percentage or to provide that certain other
provisions of this Indenture cannot be modified or waived without the consent of the
Holder of each Outstanding Security affected thereby; provided, however, that this
clause shall not be deemed to require the consent of any Holder with respect to
changes in the references to “the Trustee” and concomitant changes in this Section
and Section 6.06, or the deletion of this proviso, in accordance with the
requirements of Sections 11.06 and 14.01(f); or

66

 

          (iv) modify, without the written consent of the Trustee, the rights, duties or
immunities of the Trustee.

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

          (c) It shall not be necessary for the consent of the Securityholders under this Section 14.02
to approve the particular form of any proposed supplemental indenture, but it shall be sufficient
if such consent shall approve the substance thereof.

          (d) The Company may set a record date for purposes of determining the identity of the Holders
of each series of Securities entitled to give a written consent or waive compliance by the Company
as authorized or permitted by this Section. Such record date shall not be more than 30 days prior
to the first solicitation of such consent or waiver or the date of the most recent list of Holders
furnished to the Trustee prior to such solicitation pursuant to Section 312 of the Trust Indenture
Act.

          (e) Promptly after the execution by the Company and the Trustee of any supplemental indenture
pursuant to the provisions of this Section 14.02, the Company shall mail a notice, setting forth in
general terms the substance of such supplemental indenture, to the Holders of Securities at their
addresses as the same shall then appear in the Register of the Company. Any failure of the Company
to mail such notice, or any defect therein, shall not, however, in any way impair or affect the
validity of any such supplemental indenture.

     Section 14.03 Trustee Protected. Upon the request of the Company, accompanied by the
Officer’s Certificate and Opinion of Counsel required by Section 16.01 and evidence reasonably
satisfactory to the Trustee of consent of the Holders if the supplemental indenture is to be
executed pursuant to Section 14.02, the Trustee shall join with the Company in the execution of
said supplemental indenture unless said 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 said supplemental indenture. The Trustee
shall be fully protected in conclusively relying upon such Officer’s Certificate and an Opinion of
Counsel.

     Section 14.04 Effect of Execution of Supplemental Indenture. Upon the execution of any
supplemental indenture pursuant to the provisions of this Article XIV, this Indenture shall be
deemed to be modified and amended in accordance therewith and, except as herein otherwise expressly
provided, the respective rights, limitations of rights, obligations, duties and immunities under
this Indenture of the Trustee, the Company and the Holders of all of the Securities or of the
Securities of any series affected, as the case may be, 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.

67

 

     Section 14.05 Notation on or Exchange of Securities. 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 the form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company or the Trustee shall so determine, new
Securities so modified as to conform, in the opinion of the Trustee and the Board of Directors of
the Company, to any modification of this Indenture contained in any such supplemental indenture may
be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange
for the Securities then Outstanding in equal aggregate principal amounts, and such exchange shall
be made without cost to the Holders of the Securities.

     Section 14.06 Conformity with TIA. Every supplemental indenture executed pursuant to the
provisions of this Article shall conform to the requirements of the Trust Indenture Act as then in
effect.

     Section 14.07 Payment for Consent. Neither the Company nor any Affiliate of the Company
shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of
interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or
amendment of any of the terms or provisions of this Indenture or the Securities unless such
consideration is offered to be paid to all Holders that so consent, waive or agree to amend in the
time frame set forth in solicitation documents relating to such consent, waiver or agreement.

ARTICLE XV

SUBORDINATION OF SECURITIES

     Section 15.01 Agreement to Subordinate. In the event a series of Securities is designated
as subordinated pursuant to Section 3.01, and except as otherwise provided in a Company Order or in
one or more indentures supplemental hereto, the Company, for itself, its successors and assigns,
covenants and agrees, and each Holder of Securities of such series by his, her or its acceptance
thereof, likewise covenants and agrees, that the payment of the principal of (and premium, if any)
and interest, if any, on each and all of the Securities of such series is hereby expressly
subordinated, to the extent and in the manner hereinafter set forth, in right of payment to the
prior payment in full of all Senior Indebtedness. In the event a series of Securities is not
designated as subordinated pursuant to Section 3.01(s), this Article XV shall have no effect upon
the Securities.

     Section 15.02 Distribution on Dissolution, Liquidation and Reorganization; Subrogation of
Securities. Subject to Section 15.01, upon any distribution of assets of the Company upon any
dissolution, winding up, liquidation or reorganization of the Company, whether in bankruptcy,
insolvency, reorganization or receivership proceedings or upon an assignment for the benefit of
creditors or any other marshalling of the assets and liabilities of the Company or otherwise
(subject to the power of a court of competent jurisdiction to make other equitable provision
reflecting the rights conferred in this Indenture upon the Senior Indebtedness and the holders
thereof with respect to the Securities and the holders thereof by a lawful plan of reorganization
under applicable bankruptcy law):

68

 

          (a) the holders of all Senior Indebtedness shall be entitled to receive payment in full of the
principal thereof (and premium, if any) and interest due thereon before the Holders of the
Securities are entitled to receive any payment upon the principal (or premium, if any) or interest,
if any, on Indebtedness evidenced by the Securities; and

          (b) any payment or distribution of assets of the Company of any kind or character, whether in
cash, property or securities, to which the Holders of the Securities or the Trustee would be
entitled except for the provisions of this Article XV shall be paid by the liquidation trustee or
agent or other Person making such payment or distribution, whether a trustee in bankruptcy, a
receiver or liquidating trustee or otherwise, directly to the holders of 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 principal of (and premium, if
any) and interest on the Senior Indebtedness held or represented by each, to the extent necessary
to make payment in full of all Senior Indebtedness remaining unpaid, after giving effect to any
concurrent payment or distribution to the holders of such Senior Indebtedness; and

          (c) in the event that, notwithstanding the foregoing, any payment or distribution of assets of
the Company of any kind or character, whether in cash, property or securities prohibited by the
foregoing, shall be received by the Trustee or the Holders of the Securities before all Senior
Indebtedness is paid in full, such payment or distribution shall be paid over, upon written notice
to a Responsible Officer of the Trustee, to the holder of such Senior Indebtedness or his, her or
its representative or representatives or to the trustee or trustees under any indenture under which
any instrument evidencing any of such Senior Indebtedness may have been issued, ratably as
aforesaid, as calculated by the Company, for application to payment of all Senior Indebtedness
remaining unpaid until all such Senior Indebtedness shall have been paid in full, after giving
effect to any concurrent payment or distribution to the holders of such Senior Indebtedness.

          (d) Subject to the payment in full of all Senior Indebtedness, the Holders of the Securities
shall be subrogated to the rights of the holders of Senior Indebtedness (to the extent that
distributions otherwise payable to such holder have been applied to the payment of Senior
Indebtedness) to receive payments or distributions of cash, property or securities of the Company
applicable to Senior Indebtedness until the principal of (and premium, if any) and interest, if
any, on the Securities shall be paid in full and no such payments or distributions to the Holders
of the Securities of cash, property or securities otherwise distributable to the holders of Senior
Indebtedness shall, as between the Company, its creditors other than the holders of Senior
Indebtedness, and the Holders of the Securities be deemed to be a payment by the Company to or on
account of the Securities. It is understood that the provisions of this Article XV are and are
intended solely for the purpose of defining the relative rights of the Holders of the Securities,
on the one hand, and the holders of the Senior Indebtedness, on the other hand. Nothing contained
in this Article XV or elsewhere in this Indenture or in the Securities is intended to or shall
impair, as between the Company, its creditors other than the holders of Senior Indebtedness, and
the Holders of the Securities, the obligation of the Company, which is unconditional and absolute,
to pay to the Holders of the Securities the principal of (and premium, if any) and interest, if
any, on

69

 

the Securities as and when the same shall become due and payable in accordance with their
terms, or to affect the relative rights of the Holders of the Securities and creditors of the
Company other than the holders of Senior Indebtedness, nor shall anything herein or in the
Securities prevent the Trustee or the Holder of any Security from exercising all remedies otherwise
permitted by applicable law upon default under this Indenture, subject to the rights, if any, under
this Article XV of the holders of Senior Indebtedness in respect of cash, property or securities of
the Company received upon the exercise of any such remedy. Upon any payment or distribution of
assets of the Company referred to in this Article XV, the Trustee, subject to the provisions of
Section 15.05, shall be entitled to conclusively rely upon a certificate of the liquidating trustee
or agent or other person making any distribution to the Trustee for the purpose of ascertaining the
Persons entitled to participate in such distribution, the holders of Senior Indebtedness and other
indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereof and all other facts pertinent thereto or to this Article XV.

     Section 15.03 No Payment on Securities in Event of Default on Senior Indebtedness. Subject
to Section 15.01, no payment by the Company on account of principal (or premium, if any), sinking
funds or interest, if any, on the Securities shall be made at anytime if: (i) a default on Senior
Indebtedness exists that permits the holders of such Senior Indebtedness to accelerate its maturity
and (ii) the default is the subject of judicial proceedings or the Company has received notice of
such default. The Company may resume payments on the Securities when full payment of amounts then
due for principal (premium, if any), sinking funds and interest on Senior Indebtedness has been
made or duly provided for in money or money’s worth.

          In the event that, notwithstanding the foregoing, any payment shall be received by the Trustee
when such payment is prohibited by the preceding paragraph of this Section 15.03, such payment
shall be held in trust for the benefit of, and shall be paid over or delivered to, the holders of
such Senior Indebtedness or their respective representatives, or to the trustee or trustees under
any indenture pursuant to which any of such Senior Indebtedness may have been issued, as their
respective interests may appear, as calculated by the Company, but only to the extent that the
holders of such Senior Indebtedness (or their representative or representatives or a trustee)
notify the Trustee in writing within 90 days of such payment of the amounts then due and owing on
such Senior Indebtedness and only the amounts specified in such notice to the Trustee shall be paid
to the holders of such Senior Indebtedness.

     Section 15.04 Payments on Securities Permitted. Subject to Section 15.01, nothing contained
in this Indenture or in any of the Securities shall (a) affect the obligation of the Company to
make, or prevent the Company from making, at any time except as provided in Sections 15.02 and
15.03, payments of principal of (or premium, if any) or interest, if any, on the Securities or (b)
prevent the application by the Trustee of any moneys or assets deposited with it hereunder to the
payment of or on account of the principal of (or premium, if any) or interest, if any, on the
Securities, unless a Responsible Officer of the Trustee shall have received at its Corporate Trust
Office written notice of any fact prohibiting the making of such payment from the Company or from
the holder of any Senior Indebtedness or from the trustee for any such holder, together with proof
satisfactory to the Trustee of such holding of Senior Indebtedness or of the authority of such
trustee more than two Business Days prior to the date fixed for such payment.

70

 

     Section 15.05 Authorization of Securityholders to Trustee to Effect Subordination. Subject
to Section 15.01, each Holder of Securities by his acceptance thereof authorizes and directs the
Trustee on his, her or its behalf to take such action as may be necessary or appropriate to
effectuate the subordination as provided in this Article XV and appoints the Trustee his
attorney-in-fact for any and all such purposes.

     Section 15.06 Notices to Trustee. The Company shall give prompt written notice to a
Responsible Officer of the Trustee of any fact known to the Company that would prohibit the making
of any payment of monies or assets to or by the Trustee in respect of the Securities of any series
pursuant to the provisions of this Article XV. Subject to Section 15.01, notwithstanding the
provisions of this Article XV or any other provisions of this Indenture, neither the Trustee nor
any Paying Agent (other than the Company) shall be charged with knowledge of the existence of any
Senior Indebtedness or of any fact which would prohibit the making of any payment of moneys or
assets to or by the Trustee or such Paying Agent, unless and until a Responsible Officer of the
Trustee or such Paying Agent shall have received (in the case of a Responsible Officer of the
Trustee, at the Corporate Trust Office of the Trustee) written notice thereof from the Company or
from the holder of any Senior Indebtedness or from the trustee for any such holder, together with
proof satisfactory to the Trustee of such holding of Senior Indebtedness or of the authority of
such trustee and, prior to the receipt of any such written notice, the Trustee shall be entitled in
all respects conclusively to presume 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 moneys or assets may
become payable for any purpose (including, without limitation, the payment of either the principal
(or premium, if any) or interest, if any, on any Security) a Responsible Officer of the Trustee
shall not have received with respect to such moneys or assets the notice provided for in this
Section 15.06, then, anything herein contained to the contrary notwithstanding, the Trustee shall
have full power and authority to receive such moneys or assets 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 within two Business Days prior to such date. The Trustee shall be entitled to rely
on the delivery to it of a written notice by a Person representing himself to be a holder of Senior
Indebtedness (or a trustee on behalf of such holder) to establish that such a notice has been given
by a holder of Senior Indebtedness or a trustee on behalf of any such holder. 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 Article XV, 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, the extent
to which such Person is entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article XV 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.

     Section 15.07 Trustee as Holder of Senior Indebtedness. Subject to Section 15.01, the
Trustee in its individual capacity shall be entitled to all the rights set forth in this Article XV
in respect of any Senior Indebtedness at any time held by it to the same extent as any other holder
of Senior Indebtedness and nothing in this Indenture shall be construed to deprive the Trustee of

71

 

any of its rights as such holder. Nothing in this Article XV shall apply to claims of, or payments
to, the Trustee under or pursuant to Sections 7.05 or 11.01.

     Section 15.08 Modifications of Terms of Senior Indebtedness. Subject to Section 15.01, any
renewal or extension of the time of payment of any Senior Indebtedness or the exercise by the
holders of Senior Indebtedness of any of their rights under any instrument creating or evidencing
Senior Indebtedness, including, without limitation, the waiver of default thereunder, may be made
or done all without notice to or assent from the Holders of the Securities or the Trustee. No
compromise, alteration, amendment, modification, extension, renewal or other change of, or waiver,
consent or other action in respect of, any liability or obligation under or in respect of, or of
any of the terms, covenants or conditions of any indenture or other instrument under which any
Senior Indebtedness is outstanding or of such Senior Indebtedness, whether or not such release is
in accordance with the provisions of any applicable document, shall in any way alter or affect any
of the provisions of this Article XV or of the Securities relating to the subordination thereof.

     Section 15.09 Reliance on Judicial Order or Certificate of Liquidating Agent. Subject to
Section 15.01, upon any payment or distribution of assets of the Company referred to in this
Article XV, the Trustee and the Holders of the Securities shall be entitled to conclusively rely
upon any order or decree entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding up or similar case or
proceeding is pending, or a certificate of the trustee in bankruptcy, liquidating trustee,
custodian, receiver, assignee for the benefit of creditors, agent or other person making such
payment or distribution, delivered to the Trustee or to the Holders of Securities, for the purpose
of ascertaining the Persons entitled to participate in such payment or distribution, the holders of
Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this
Article XV.

     Section 15.10 Satisfaction and Discharge; Defeasance and Covenant Defeasance. Subject to
Section 15.01, amounts and U.S. Government Obligations deposited in trust with the Trustee pursuant
to and in accordance with Article XII and not, at the time of such deposit, prohibited to be
deposited under Sections 15.02 or 15.03 shall not be subject to this Article XV.

     Section 15.11 Trustee Not Fiduciary for Holders of Senior Indebtedness. With respect to
the holders of Senior Indebtedness, the Trustee undertakes to perform or observe only such of its
covenants and obligations as are specifically set forth in this Article XV, and no implied
covenants or obligations with respect to the holders of Senior Indebtedness shall be read into this
Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness. The Trustee shall not be liable to any such holder if it shall pay
over or distribute to or on behalf of Holders of Securities or the Company, or any other Person,
moneys or assets to which any holder of Senior Indebtedness shall be entitled by virtue of this
Article XV or otherwise.

          (b) In the event of suspension of regular mail service or by reason of any other cause it
