SECTION 104. Acts of Holders; Record Dates.

     Whenever in this Indenture it is provided that the Holders of a specified percentage in
aggregate principal amount of the Securities of any or all series may take action (including the
making of any demand or request, the giving of any direction, 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 have joined therein may be evidenced (a) by any instrument or any number of
instruments of similar tenor executed by Holders in person or by agent or proxy appointed in
writing, (b) by the record of the Holders voting in favor thereof at any meeting of Holders duly
called and held in accordance with procedures approved by the Trustee, (c) by a combination of such
instrument or instruments and any such record of such a meeting of Holders or (d) in the case of
Securities evidenced by a Global Security, by any electronic transmission or other message, whether
or not in written format, that complies with the Depositary’s applicable procedures. Such evidence
(and the action embodied therein and evidenced thereby) are herein sometimes referred to as the
“Act” of the relevant Holders. Proof of execution of any such instrument or of a writing
appointing any such agent or proxy shall be sufficient for any purpose of this Indenture and
(subject to Section 601) conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Section.

     The fact and date of the execution by any Person of any such instrument or writing may be
proved by the affidavit of a witness of such execution or by a certificate of a notary public or
other officer authorized by law to take acknowledgments of deeds, certifying that the individual
signing such instrument or writing acknowledged to him the execution thereof. Where such execution
is by a signer acting in a capacity other than his individual capacity, such certificate or
affidavit shall also constitute sufficient proof of his authority. The fact and date of the
execution of any such instrument or writing, or the authority of the Person executing the same, may
also be proved in any other manner that the Trustee deems sufficient.

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

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

     The Company may set any day as a record date for the purpose of determining the Holders of
Outstanding Securities of any series entitled to give, make or take any request, demand,
authorization, direction, notice, consent, waiver or other action provided or permitted by this
Indenture to be given, made or taken by Holders of Securities of such series, provided that the
Company may not set a record date for, and the provisions of this paragraph shall not apply with
respect to, the giving or making of any notice, declaration, request or direction referred to in
the next paragraph. If any record date is set pursuant to this paragraph, the Holders of
Outstanding Securities of the relevant series on such record date, and no other Holders, shall be
entitled to take the relevant action, whether or not such Holders remain Holders after such record
date; provided that no such action shall be effective hereunder unless taken on or prior to the
applicable Expiration Date by Holders of the requisite principal amount of Outstanding

9

 

Securities of such series on such record date. Nothing in this paragraph shall be construed
to prevent the Company from setting a new record date for any action for which a record date has
previously been set pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be cancelled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders of the requisite
principal amount of Outstanding Securities of the relevant series on the date such action is taken.
Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense,
shall cause notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the
relevant series in the manner set forth in Section 106.

     The Trustee may set any day as a record date for the purpose of determining the Holders of
Outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of
Default, (ii) any declaration of acceleration referred to in Section 502, (iii) any request to
institute proceedings referred to in Section 507(2) or (iv) any direction referred to in Section
512, in each case with respect to Securities of such series. If any record date is set pursuant to
this paragraph, the Holders of Outstanding Securities of such series on such record date, and no
other Holders, shall be entitled to join in such notice, declaration, request or direction, whether
or not such Holders remain Holders after such record date; provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the
requisite principal amount of Outstanding Securities of such series on such record date. Nothing
in this paragraph shall be construed to prevent the Trustee from setting a new record date for any
action for which a record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person be cancelled and of
no effect), and nothing in this paragraph shall be construed to render ineffective any action taken
by Holders of the requisite principal amount of Outstanding Securities of the relevant series on
the date such action is taken. Promptly after any record date is set pursuant to this paragraph,
the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action
by Holders and the applicable Expiration Date to be given to the Company in writing and to each
Holder of Securities of the relevant series in the manner set forth in Section 106.

     With respect to any record date set pursuant to this Section, the party hereto which sets such
record dates may designate any day as the “Expiration Date” and from time to time may change the
Expiration Date to any earlier or later day; provided that no such change shall be effective unless
notice of the proposed new Expiration Date is given to the other party hereto in writing, and to
each Holder of Securities of the relevant series in the manner set forth in Section 106, on or
prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any
record date set pursuant to this Section, the party hereto which set such record date shall be
deemed to have initially designated the 180th day after such record date as the Expiration Date
with respect thereto, subject to its right to change the Expiration Date as provided in this
paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day
after the applicable record date.

     Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with
regard to any particular Security may do so with regard to all or any part of the principal

10

 

amount of such Security or by one or more duly appointed agents each of which may do so
pursuant to such appointment with regard to all or any part of such principal amount.

SECTION 105. Notices, Etc., to Trustee and Company.

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

     (1) the Trustee by any Holder or by the Company or any Subsidiary Guarantor shall be
sufficient for every purpose hereunder if made, given, furnished or filed in writing in the
English language to or with the Trustee at 1445 Ross Avenue, 2nd Floor, Dallas, Texas,
75202, Attention: Corporate Trust Department, Telecopy No. (214) 777-4086; or

     (2) the Company or any Subsidiary Guarantor by the Trustee or by any Holder shall be
sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in
writing in the English language and mailed, first-class postage prepaid, in the case of the
Company addressed to it at the address of its principal office specified in the first
paragraph of this instrument or at any other address previously furnished in writing to the
Trustee by the Company and, in the case of any Subsidiary Guarantor, to it at the address of
the Company’s principal office specified in the first paragraph of this instrument,
Attention: Chief Financial Officer, or at any other address previously furnished in writing
to the Trustee by such Subsidiary Guarantor.

SECTION 106. Notice to Holders; Waiver.

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

     In case by reason of the suspension of regular mail service or by reason of any other cause it
shall be impracticable to give such notice by mail, then such notification as shall be made with
the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

11

 

SECTION 107. Conflict with Trust Indenture Act.

     If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture
Act which is required under such Act to be a part of and govern this Indenture, the latter
provision shall control. If any provision of this Indenture modifies or excludes any provision of
the Trust Indenture Act which may be so modified or excluded, the latter provision shall be deemed
to apply to this Indenture as so modified or to be excluded, as the case may be.

SECTION 108. Effect of Headings and Table of Contents.

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

SECTION 109. Successors and Assigns.

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

SECTION 110. Separability Clause.

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

SECTION 111. Benefits of Indenture.

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

SECTION 112. Governing Law.

     This Indenture, the Securities and the Subsidiary Guarantees shall be governed by and
construed in accordance with the law of the State of New York.

SECTION 113. Legal Holidays.

     In any case where any Interest Payment Date, Redemption Date, purchase date or Stated Maturity
of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any
other provision of this Indenture or of the Securities (other than a provision of any Security
which specifically states that such provision shall apply in lieu of this Section)) payment of
interest or principal (and premium, if any) need not be made at such Place of Payment on such date,
but may be made on the next succeeding Business Day at such Place of Payment with the same force
and effect as if made on the Interest Payment Date, Redemption Date or purchase date, or at the
Stated Maturity.

called the “Company”, which term includes any successor Person under the Indenture hereinafter
referred to), for value received, hereby promises to pay to                                         , or
registered assigns, the principal sum of                                          Dollars on
                                         [if the Security is to bear interest prior to Maturity, insert
— , and to pay interest thereon from                      or from the most recent Interest Payment Date
to which interest has been paid or duly provided for, semi-annually on                      and

annum (to the extent that the payment of such interest shall be legally enforceable), from the

shall be payable on demand.

13

 

The interest so payable, and punctually paid or duly provided for, on any Interest Payment

or more Predecessor Securities) is registered at the close of business on the Regular Record Date

case may be, next preceding such Interest Payment Date. Any such interest not so punctually paid
or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date
and may either be paid to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on a Special Record Date for the payment of such
Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of
Securities of this series not less than 10 days prior to such Special Record Date, or be paid at
any time in any other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities of this series may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in said Indenture].

     [If the Security is not to bear interest prior to Maturity, insert — The principal of this
Security shall not bear interest except in the case of a default in payment of principal upon
acceleration, upon redemption or at Stated Maturity and in such case the overdue principal and any
overdue premium shall bear interest at the rate of ___% per annum (to the extent that the payment
of such interest shall be legally enforceable), from the dates such amounts are due until they are

on demand. Any such interest on overdue principal or premium which is not paid on demand shall
bear interest at the rate of ___% per annum (to the extent that the payment of such interest on
interest shall be legally enforceable), from the date of such demand until the amount so demanded
is paid or made available for payment. Interest on any overdue interest shall be payable on
demand.]

interest on this Security will be made at the office or agency of the Company maintained for that
purpose in                     , in such coin or currency of the United States of America as at the time of

option of the Company payment of interest may be made by check mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register.

     Reference is hereby made to the further provisions of this Security set forth on the reverse

principal amount of Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60 days after receipt of
such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted
by the Holder of this Security for the enforcement of any payment of principal hereof or any
premium or interest hereon on or after the respective due dates expressed herein.

     No reference herein to the Indenture and no provision of this Security or of the Indenture
shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay
the principal of and any premium and interest on this Security at the times, place and rate, and in
the coin or currency, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set forth, the

principal of and any premium and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing,

transferee or transferees.

     The Securities of this series are issuable only in registered form without coupons in
denominations of $                      and any integral multiple thereof. As provided in the Indenture and

SECTION 204. Form of Subsidiary Guarantee.

SUBSIDIARY GUARANTEE

     For value received, each of the Subsidiary Guarantors named (or deemed herein to be named)
below hereby jointly and severally fully and unconditionally guarantees to the Holder of the
Security upon which this Subsidiary Guarantee is endorsed, and to the Trustee on behalf of such
Holder, the due and punctual payment of the principal of (and premium, if any) and interest on such
Security when and as the same shall become due and payable, whether at the Stated Maturity, by
acceleration, call for redemption, offer to purchase or otherwise, according to the terms thereof
and of the Indenture referred to therein and to cover all the rights of the Trustee under Section
607. In case of the failure of the Company punctually to make any such payment, each of the
Subsidiary Guarantors hereby jointly and severally agrees to cause such payment to be made
punctually when and as the same shall become due and payable, whether at the Stated Maturity or by
acceleration, call for redemption, offer to purchase or otherwise, and as if such payment were made
by the Company.

     Each of the Subsidiary Guarantors hereby jointly and severally agrees that its obligations
hereunder shall be absolute and unconditional, irrespective of, and shall be unaffected by, the
validity, regularity or enforceability of such Security or the Indenture, the absence of any action
to enforce the same or any release, amendment, waiver or indulgence granted to the Company or any
other guarantor, or any consent to departure from any requirement of any other guarantee of all or
of any of the Securities of this series, or any other circumstances which might otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor; provided, however,
that, notwithstanding the foregoing, no such release, amendment, waiver or indulgence shall,
without the consent of such Subsidiary Guarantor, increase the principal amount of such Security,
or increase the interest rate thereon, or alter the Stated Maturity thereof. Each of the
Subsidiary Guarantors hereby waives the benefits of diligence, presentment, demand of payment, any
requirement that the Trustee or any of the Holders protect, secure, perfect or insure any security
interest in or other lien on any property subject thereto or exhaust any right or take any action
against the Company or any other Person or any collateral, filing of claims with a court in the
event of insolvency or bankruptcy of the Company, any right to require a proceeding first against
the Company, protest or notice with respect to such Security or the indebtedness evidenced thereby
and all demands whatsoever, and covenants that this Subsidiary Guarantee will not be discharged
except by complete performance of the obligations contained in such Security and in this Subsidiary
Guarantee. Each Subsidiary Guarantor agrees that if, after the occurrence and during the
continuance of an Event of Default with respect to Securities of this series, the Trustee or any of
the Holders are prevented by applicable law from exercising their respective rights to accelerate
the maturity of the Securities of this series, to collect interest on the Securities of this
series, or to enforce or exercise any other right or remedy with respect to

19

 

the Securities of this series, such Subsidiary Guarantor agrees to pay to the Trustee for the
account of the Holders, upon demand therefor, the amount that would otherwise have been due and
payable had such rights and remedies been permitted to be exercised by the Trustee or any of the
Holders.

     No reference herein to the Indenture and no provision of this Subsidiary Guarantee or of the
Indenture shall alter or impair the Subsidiary Guarantee of any Subsidiary Guarantor, which is
absolute and unconditional, of the due and punctual payment of the principal (and premium, if any)
and interest on the Security upon which this Subsidiary Guarantee is endorsed.

     Each Subsidiary Guarantor shall be subrogated to all rights of the Holder of this Security
against the Company in respect of any amounts paid by such Subsidiary Guarantor on account of this
Security pursuant to the provisions of its Subsidiary Guarantee or the Indenture; provided,
however, that such Subsidiary Guarantor shall not be entitled to enforce or to receive any payments
arising out of, or based upon, such right of subrogation until the principal of (and premium, if
any) and interest on this Security and all other Securities of this series issued under the
Indenture shall have been paid in full.

     This Subsidiary Guarantee shall remain in full force and effect and continue to be effective
should any petition be filed by or against the Company for liquidation or reorganization, should
the Company become insolvent or make an assignment for the benefit of creditors or should a
receiver or trustee be appointed for all or any part of the Company’s assets, and shall, to the
fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if
at any time payment and performance of the Securities of this series is, pursuant to applicable
law, rescinded or reduced in amount, or must otherwise be restored or returned by any Holder of the
Securities of this series, whether as a “voidable preference”, “fraudulent transfer”, or otherwise,
all as though such payment or performance had not been made. In the event that any payment, or any
part thereof, is rescinded, reduced, restored or returned, the Securities of this series shall, to
the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and
not so rescinded, reduced, restored or returned.

     The Subsidiary Guarantors or any particular Subsidiary Guarantor shall be released from this
Subsidiary Guarantee upon the terms and subject to certain conditions provided in the Indenture.

     By delivery to the Trustee of a supplement to the Indenture referred to in the Security upon
which this Subsidiary Guarantee is endorsed in accordance with the terms of the Indenture, each
Person that becomes a Subsidiary Guarantor after the date of first issuance of the Securities of
this series will be deemed to have executed and delivered this Subsidiary Guarantee for the benefit
of the Holder of the Security upon which this Subsidiary Guarantee is endorsed with the same effect
as if such Subsidiary Guarantor was named below and has executed and delivered this Subsidiary
Guarantee.

     All terms used in this Subsidiary Guarantee which are defined in the Indenture shall have the
meanings assigned to them in such Indenture.

20

 

     This Subsidiary Guarantee shall not be valid or obligatory for any purpose until the
certificate of authentication on the Security upon which this Subsidiary Guarantee is endorsed
shall have been executed by the Trustee under the Indenture by manual signature.

     Reference is made to the Indenture for further provisions with respect to this Subsidiary
Guarantee.

     This Subsidiary Guarantee shall be governed by and construed in accordance with the laws of
the State of New York.

     IN WITNESS WHEREOF, each of the Subsidiary Guarantors has caused this Subsidiary Guarantee to
be duly executed.

only in such denominations as shall be specified as contemplated by Section 301. In the absence of
any such specified denomination with respect to the Securities of any series, the Securities of
such series shall be issuable in denominations of $1,000 and any integral multiple thereof.

25

 

SECTION 303. Execution, Authentication, Delivery and Dating.

     The Securities shall be executed on behalf of the Company by its Chairman of the Board of
Directors, its Vice Chairman of the Board of Directors, its President or one of its Vice
Presidents. If its corporate seal is reproduced thereon, then it shall be attested by its
Secretary or one of its Assistant Secretaries. The signature of any of these officers on the
Securities may be manual or facsimile.

     Securities bearing the manual or facsimile signatures of individuals who were at any time the
proper officers of the Company shall bind the Company, notwithstanding that such individuals or any
of them have ceased to hold such offices prior to the authentication and delivery of such
Securities or did not hold such offices at the date of such Securities.

     At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Securities of any series executed by the Company and, if applicable, having
endorsed thereon the Subsidiary Guarantees executed as provided in Section 1303 by the Subsidiary
Guarantors to the Trustee for authentication, together with a Company Order for the authentication
and delivery of such Securities, and the Trustee in accordance with the Company Order shall
authenticate and deliver such Securities. If the form or terms of the Securities of the series
have been established by or pursuant to one or more Board Resolutions as permitted by Sections 201
and 301, in authenticating such Securities, and accepting the additional responsibilities under
this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and
(subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating,

     (1) if the form of such Securities has been established by or pursuant to Board
Resolution as permitted by Section 201, that such form has been established in conformity
with the provisions of this Indenture;

     (2) if the terms of such Securities have been established by or pursuant to Board
Resolution as permitted by Section 301, that such terms have been established in conformity
with the provisions of this Indenture; and

     (3) that such Securities, when authenticated and delivered by the Trustee and issued by
the Company in the manner and subject to any conditions specified in such Opinion of
Counsel, will constitute valid and legally binding obligations of the Company, and, if
applicable, the Subsidiary Guarantees endorsed thereon will constitute valid and legally
binding obligations of the Subsidiary Guarantors, enforceable in accordance with their
terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium
and similar laws of general applicability relating to or affecting creditors’ rights and to
general equity principles.

If such form or terms have been so established, the Trustee shall not be required to authenticate
such Securities if the issue of such Securities pursuant to this Indenture will affect the
Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in
a manner which is not reasonably acceptable to the Trustee.

26

 

     Notwithstanding the provisions of Section 301 and of the preceding paragraph, if all
Securities of a series are not to be originally issued at one time, it shall not be necessary to
deliver the Officers’ Certificate otherwise required pursuant to Section 301 or the Company Order
and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered at or prior to the
authentication upon original issuance of the first Security of such series to be issued.

     Each Security shall be dated the date of its authentication.

     No Security or Subsidiary Guarantee shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Security a certificate of
authentication substantially in the form provided for herein executed by the Trustee by manual
signature, and such certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding
the foregoing, if any Security shall have been authenticated and delivered hereunder but never
issued and sold by the Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided in Section 309, for all purposes of this Indenture such Security shall be
deemed never to have been authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

SECTION 304. Temporary Securities.

     Pending the preparation of definitive Securities of any series, the Company may execute, and
upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are
printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Securities and, if applicable, having
endorsed thereon the Subsidiary Guarantees in lieu of which they are issued and with such
appropriate insertions, omissions, substitutions and other variations as the officers executing
such Securities and, if applicable, Subsidiary Guarantees may determine, as evidenced by their
execution of such Securities and Subsidiary Guarantees.

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

27

 

SECTION 305. Registration, Registration of Transfer and Exchange.

     The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register
(the register maintained in such office and in any other office or agency of the Company in a Place
of Payment being herein sometimes collectively referred to as the “Security Register”) in which,
subject to such reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is hereby appointed
“Security Registrar” for the purpose of registering Securities and transfers of Securities as
herein provided.

     Upon surrender for registration of transfer of any Security of a series at the office or
agency of the Company in a Place of Payment for that series, the Company shall execute, if
applicable the Subsidiary Guarantors shall execute the Subsidiary Guarantees endorsed thereon and
the Trustee shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount.

     At the option of the Holder, Securities of any series may be exchanged for other Securities of
the same series, of any authorized denominations and of like tenor and aggregate principal amount,
upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities
are so surrendered for exchange, the Company shall execute, if applicable the Subsidiary Guarantors
shall execute the Subsidiary Guarantees endorsed thereon and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to receive.

     All Securities and, if applicable, the Subsidiary Guarantees endorsed thereon issued upon any
registration of transfer or exchange of Securities shall be the valid obligations of the Company
and, if applicable, the respective Subsidiary Guarantors, evidencing the same debt, and entitled to
the same benefits under this Indenture, as the Securities and Subsidiaries Guarantees surrendered
upon such registration of transfer or exchange.

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

     No service charge shall be made for any registration of transfer or exchange of Securities,
but the Company may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer or exchange of
Securities, other than exchanges pursuant to Section 304, 906, 1107 or otherwise not involving any
transfer.

     If the Securities of any series (or of any series and specified tenor) are to be redeemed in
part, the Company shall not be required (A) to issue, register the transfer of or exchange any
Securities of that series (or of that series and specified tenor, as the case may be) during a
period beginning at the opening of business 15 days before the day of the mailing of a notice of
redemption of any such Securities selected for redemption under Section 1103 and ending at the

28

 

close of business on the day of such mailing, or (B) to register the transfer of or exchange
any Security so selected for redemption in whole or in part, except the unredeemed portion of any
Security being redeemed in part.

The provisions of clauses (1), (2), (3) and (4) below shall apply only to Global Securities:

     (1) Each Global Security authenticated under this Indenture shall be registered in the
name of the Depositary designated for such Global Security or a nominee thereof and
delivered to such Depositary or a nominee thereof or custodian therefor, and each such
Global Security shall constitute a single Security for all purposes of this Indenture.

     (2) Notwithstanding any other provision in this Indenture, no Global Security may be
exchanged in whole or in part for Securities registered, and no transfer of a Global
Security in whole or in part may be registered, in the name of any Person other than the
Depositary for such Global Security or a nominee thereof unless (A) such Depositary (i) has
notified the Company that it is unwilling or unable to continue as Depositary for such
Global Security or (ii) has ceased to be a clearing agency registered under the Exchange
Act, and in either case the Company fails to appoint a successor Depositary within 90 days,
(B) there shall have occurred and be continuing an Event of Default with respect to such
Global Security and the Depositary shall have notified the Trustee of its decision to
exchange such Global Security for Securities in certificated form or (C) there shall exist
such circumstances, if any, in addition to or in lieu of the foregoing as have been
specified for this purpose as contemplated by Section 301.

     (3) Subject to clause (2) above, any exchange of a Global Security for other Securities
may be made in whole or in part, and all Securities issued in exchange for a Global Security
or any portion thereof shall be registered in such names as the Depositary for such Global
Security shall direct.

     (4) Every Security authenticated and delivered upon registration of transfer of, or in
exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to
this Section, Section 304, 306, 906 or 1107 or otherwise, shall be authenticated and
delivered in the form of, and shall be, a Global Security, unless such Security is
registered in the name of a Person other than the Depositary for such Global Security or a
nominee thereof.

SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities.

     If any mutilated Security is surrendered to the Trustee, the Company shall execute, if
applicable the Subsidiary Guarantors shall execute the Subsidiary Guarantees endorsed thereon and
the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series
and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

     If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction
of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be
required by them to save each of them and any agent of either of them harmless from any loss that
any of them may suffer if a Security is replaced, then, in the absence of notice to the

29

 

Company or the Trustee that such Security has been acquired by a bona fide purchaser, the
Company shall execute, if applicable the Subsidiary Guarantors shall execute the Subsidiary
Guarantees endorsed thereon and the Trustee shall authenticate and deliver, in lieu of any such
destroyed, lost or stolen Security, a new Security of the same series and of like tenor and
principal amount and bearing a number not contemporaneously outstanding.

     In case any such mutilated, destroyed, lost or stolen Security has become or is about to
become due and payable or is to be converted, the Company in its discretion may, instead of issuing
a new Security, pay or authorize the conversion of such Security (without surrender thereof save in
the case of a mutilated Security).

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

     Every new Security of any series issued pursuant to this Section in lieu of any destroyed,
lost or stolen Security, and, if applicable, the Subsidiary Guarantees endorsed thereon, shall
constitute an original additional contractual obligation of the Company and, if applicable, the
respective Subsidiary Guarantors, whether or not the destroyed, lost or stolen Security shall be at
any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally
and proportionately with any and all other Securities of that series duly issued hereunder.

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

SECTION 307. Payment of Interest; Interest Rights Preserved.

     Except as otherwise provided as contemplated by Section 301 with respect to any series of
Securities, interest on any Security which is payable, and is punctually paid or duly provided for,
on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or
more Predecessor Securities) is registered at the close of business on the Regular Record Date for
such interest.

     Any interest on any Security of any series which is payable, but is not punctually paid or
duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall
forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having
been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (1) or (2) below:

     (1) The Company may elect to make payment of any Defaulted Interest to the Persons in
whose names the Securities of such series (or their respective Predecessor Securities) are
registered at the close of business on a Special Record Date for the payment of such
Defaulted Interest, which shall be fixed in the following manner. The Company shall notify
the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each
Security of such series and the date of the proposed payment, and at the same time the
Company shall deposit with the Trustee an amount of money equal to

30

 

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 days and not less than 10 days prior to the date of the proposed
payment and not less than 10 days after the receipt by the Trustee of the notice of the
proposed payment. The Trustee shall promptly notify the Company of such Special Record Date
and, in the name and at the expense of the Company, shall cause notice of the proposed
payment of such Defaulted Interest and the Special Record Date therefor to be given to each
Holder of Securities of such series in the manner set forth in Section 106, not less than 10
days prior to such Special Record Date. Notice of the proposed payment of such Defaulted
Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest
shall be paid to the Persons in whose names the Securities of such series (or their
respective Predecessor Securities) are registered at the close of business on such Special
Record Date and shall no longer be payable pursuant to the following clause (2).

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

     Subject to the foregoing provisions of this Section, each Security delivered under this
Indenture upon registration of transfer of or in exchange for or in lieu of any other Security
shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such
other Security.

SECTION 308. Persons Deemed Owners.

     Prior to due presentment of a Security for registration of transfer, the Company, the
Subsidiary Guarantors, the Trustee and any agent of the Company, the Subsidiary Guarantors, or the
Trustee may treat the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and any premium and (subject to
Section 307) any interest on such Security and for all other purposes whatsoever, whether or not
such Security be overdue, and neither the Company, any Subsidiary Guarantor, the Trustee nor any
agent of the Company, any Subsidiary Guarantor, or the Trustee shall be affected by notice to the
contrary.

SECTION 309. Cancellation.

     All Securities surrendered for payment, redemption, purchase, registration of transfer or
exchange or for credit against any sinking fund payment shall, if surrendered to any Person other
than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company
may at any time deliver to the Trustee for cancellation any Securities previously

31

 

authenticated and delivered hereunder which the Company may have acquired in any manner
whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for
cancellation any Securities previously authenticated hereunder which the Company has not issued and
sold, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities
shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this
Section, except as expressly permitted by this Indenture. All cancelled Securities held by the
Trustee shall be disposed of as directed by a Company Order.

SECTION 310. Computation of Interest.

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

delivered (other than (i) Securities of such series which have been
destroyed, lost or stolen and which have been replaced or paid as provided
in Section 306 and (ii) Securities of such series for whose payment money

and the Company or, if applicable, a Subsidiary Guarantor, in the case of (i), (ii)
or (iii) above, has irrevocably deposited or caused to be deposited with the Trustee
as trust funds in trust for the purpose money in an amount sufficient, without
consideration of any reinvestment of interest, to pay and discharge the entire
indebtedness on such Securities not theretofore delivered to the Trustee for
cancellation, for principal and any premium and interest to the date of such deposit
(in the case of Securities which have become due and payable) or to the Stated
Maturity or Redemption Date, as the case may be;

     (2) the Company or a Subsidiary Guarantor has paid or caused to be paid all other sums

Company to the Trustee under Section 607, any surviving rights of conversion, the obligations of
the Trustee to any Authenticating Agent under Section 614 and, if money shall have been deposited
with the Trustee pursuant to subclause (B) of clause (1) of this Section, the obligations of the

SECTION 402. Application of Trust Money.

     Subject to the provisions of the last paragraph of Section 1003, all money deposited with the
Trustee pursuant to Section 401 shall be held in trust and applied by it, in accordance with the
provisions of the Securities and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine,
to the Persons entitled thereto, of the principal and any premium and interest for whose payment
such money has been deposited with the Trustee.

ARTICLE FIVE

Section specifically dealt with or which has expressly been included in this Indenture
solely for the benefit of series of Securities other than that series), and continuance of
such default or breach for a period of 60 days after there has been given, by registered or
certified mail, to the Company by the Trustee or to the Company and the Trustee by the

held by a final non-appealable order or judgment of a court of competent jurisdiction to be
unenforceable or invalid or ceases for any reason to be in full force and effect (other than
in accordance with the terms of this Indenture) or such Subsidiary Guarantor or any Person
acting on behalf of such Subsidiary Guarantor denies or disaffirms such Subsidiary
Guarantor’s obligations under its Subsidiary Guarantee (other than by reason of a release of
such Subsidiary Guarantor from its Subsidiary Guarantee in accordance with the terms of this
Indenture); or

     (9) any other Event of Default provided with respect to Securities of that series.

SECTION 502. Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default (other than an Event of Default with respect to the Company specified
in Section 501(6) or 501(7)) with respect to Securities of any series at the time Outstanding
occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25%
in principal amount of the Outstanding Securities of that series may declare the principal amount
of all the Securities of that series (or, if any Securities of that series are Original Issue
Discount Securities, such portion of the principal amount of such Securities as may be specified by
the terms thereof) to be due and payable immediately, by a notice in writing to the Company (and to
the Trustee if given by Holders), and upon any such declaration such principal amount (or specified
amount) shall become immediately due and payable, together with any accrued and unpaid interest
thereon. If an Event of Default with respect to the Company specified in Section 501(6) or 501(7)
with respect to Securities of any series at the time Outstanding occurs, the principal amount of
all the Securities of that series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be specified by the
terms thereof) shall automatically, and without any declaration or other action on the part of the
Trustee or any Holder, become immediately due and payable, together with any accrued and unpaid
interest thereon.

35

 

     At any time after such a declaration of acceleration with respect to Securities of any series
has been made and before a judgment or decree for payment of the money due has been obtained by the
Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of
the Outstanding Securities of that series, by written notice to the Company and the Trustee, may
rescind and annul such declaration and its consequences if

     (1) the Company or, if applicable, any Subsidiary Guarantor has paid or deposited with
the Trustee a sum sufficient to pay

     (A) all overdue interest on all Securities of that series,

     (B) the principal of (and premium, if any, on) any Securities of that
series which have become due otherwise than by such declaration of
acceleration and any interest thereon at the rate or rates prescribed
therefor in such Securities,

     (C) to the extent that payment of such interest is lawful, interest
upon overdue interest at the rate or rates prescribed therefor in such
Securities, and

     (D) all sums paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel;

and

     (2) all Events of Default with respect to Securities of that series, other than the
non-payment of the principal of Securities of that series which has become due solely by
such declaration of acceleration, have been cured or waived as provided in Section 513.

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

SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee.

     The Company covenants that if

     (1) default is made in the payment of any interest on any Security when such interest
becomes due and payable and such default continues for a period of 30 days, or

     (2) default is made in the payment of the principal of (or premium, if any, on) any
Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such
Securities, the whole amount then due and payable on such Securities for principal and any premium
and interest and, to the extent that payment of such interest shall be legally enforceable,
interest on any overdue principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be

36

 

sufficient to cover the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

     If an Event of Default with respect to Securities of any series occurs and is continuing, the
Trustee may in its discretion proceed to protect and enforce its rights and the rights of the
Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall
deem most effectual to protect and enforce any such rights, whether for the specific enforcement of
any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein,
or to enforce any other proper remedy.

SECTION 504. Trustee May File Proofs of Claim.

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

     No provision of this Indenture shall be deemed to authorize the Trustee to authorize or
consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or any Subsidiary Guarantee or the rights of any
Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any
such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the
election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other
similar committee.

SECTION 505. Trustee May Enforce Claims Without Possession of Securities.

     All rights of action and claims under this Indenture or the Securities or any Subsidiary
Guarantee may be prosecuted and enforced by the Trustee without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and any such proceeding
instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable
benefit of the Holders of the Securities in respect of which such judgment has been recovered.

SECTION 506. Application of Money Collected.

     Any money collected by the Trustee pursuant to this Article shall be applied in the following
order, at the date or dates fixed by the Trustee and, in case of the distribution of such

37

 

money on account of principal or any premium or interest, upon presentation of the Securities and the
notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

     FIRST: To the payment of all amounts due the Trustee under Section 607;

     SECOND: To the payment of the amounts then due and unpaid for principal of and
any premium and interest on the Securities in respect of which or for the benefit of
which such money has been collected, ratably, without preference or priority of any
kind, according to the amounts due and payable on such Securities for principal and
any premium and interest, respectively; and

     THIRD: The balance, if any, to the Company or to such other Person as a court
of competent jurisdiction shall direct.

SECTION 507. Limitation on Suits.

     No Holder of any Security of any series shall have any right to institute any proceeding,
judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or
trustee, or for any other remedy hereunder, unless

     (1) such Holder has previously given written notice to the Trustee of a continuing
Event of Default with respect to the Securities of that series;

     (2) the Holders of not less than 25% in principal amount of the Outstanding Securities
of that series shall have made written request to the Trustee to institute proceedings in
respect of such Event of Default in its own name as Trustee hereunder;

     (3) such Holder or Holders have offered to the Trustee reasonable security or indemnity
against the costs, expenses and liabilities to be incurred in compliance with such request;

     (4) the Trustee for 60 days after its receipt of such notice, request and offer of
security or indemnity has failed to institute any such proceeding; and

     (5) no direction inconsistent with such written request has been given to the Trustee
during such 60-day period by the Holders of a majority in principal amount of the
Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall have any right in any
manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb
or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or
preference over any other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such Holders.

38

 

SECTION 508. Unconditional Right of Holders to Receive Principal, Premium and Interest.

     Notwithstanding any other provision in this Indenture, the Holder of any Security shall have
the right, which is absolute and unconditional, to receive payment of the principal of and any
premium and (subject to Section 307) interest on such Security on the respective Stated Maturities
expressed in such Security (or, in the case of redemption or offer by the Company to purchase the
Securities pursuant to the terms of this Indenture, on the Redemption Date or purchase date, as
applicable) and, if applicable, to convert such Security in accordance with its terms, and to
institute suit for the enforcement of any such right, and such rights shall not be impaired without
the consent of such Holder.

SECTION 509. Restoration of Rights and Remedies.

     If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy
under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has
been determined adversely to the Trustee or to such Holder, then and in every such case, subject to
any determination in such proceeding, the Company, the Subsidiary Guarantors, the Trustee and the
Holders shall be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

SECTION 510. Rights and Remedies Cumulative.

     Except as otherwise provided with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy
herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of
any other right or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

SECTION 511. Delay or Omission Not Waiver.

     No delay or omission of the Trustee or of any Holder of any Securities to exercise any right
or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a
waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by
this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

SECTION 512. Control by Holders.

     The Holders of a majority in principal amount of the Outstanding Securities of any series
shall have the right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with
respect to the Securities of such series, provided that

39

 

     (1) such direction shall not be in conflict with any rule of law or with this
Indenture, and

     (2) the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction.

SECTION 513. Waiver of Past Defaults.

     The Holders of not less than a majority in principal amount of the Outstanding Securities of
any series may on behalf of the Holders of all the Securities of such series waive any past default
hereunder with respect to such series and its consequences, except a default

     (1) in the payment of the principal of or any premium or interest on any Security of
such series (including any Security which is required to have been purchased by the Company
pursuant to an offer to purchase by the Company made pursuant to the terms of this
Indenture), or

     (2) in respect of a covenant or provision hereof which under Article Nine cannot be
modified or amended without the consent of the Holder of each Outstanding Security of such
series.

     Upon any such waiver, such default shall cease to exist, and any Event of Default arising
therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such
waiver shall extend to any subsequent or other default or impair any right consequent thereon.

SECTION 514. Undertaking for Costs.

     In any suit for the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require
any party litigant in such suit to file an undertaking to pay the costs of such suit, and may
assess costs against any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided, however, that neither this Section nor the Trust Indenture Act shall be
deemed to authorize any court to require such an undertaking or to make such an assessment in any
suit instituted by the Company or any Subsidiary Guarantor.

SECTION 515. Waiver of Usury, Stay or Extension Laws.

     Each of the Company and the Subsidiary Guarantors covenants (to the extent that it may
lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now
or at any time hereafter in force, which may affect the covenants or the performance of this
Indenture; and each of the Company and the Subsidiary Guarantors (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that
it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but
will suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE SIX

THE TRUSTEE

SECTION 601. Certain Duties and Responsibilities.

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

SECTION 602. Notice of Defaults.

     If a default occurs hereunder with respect to Securities of any series, the Trustee shall give
the Holders of Securities of such series notice of such default as and to the extent provided by
the Trust Indenture Act; provided, however, that in the case of any default of the character
specified in Section 501(5) with respect to Securities of such series, no such notice to Holders
shall be given until at least 30 days after the occurrence thereof. For the purpose of this
Section, the term “default” means any event which is, or after notice or lapse of time or both
would become, an Event of Default with respect to Securities of such series.

SECTION 603. Certain Rights of Trustee.

     Subject to the provisions of Section 601:

     (1) the Trustee may rely and shall be protected in acting or refraining from acting
upon any resolution, certificate, statement, instrument, opinion, report, notice, request,
direction, consent, order, bond, debenture, note, other evidence of indebtedness or other
paper or document believed by it to be genuine and to have been signed or presented by the
proper party or parties;

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

     (3) whenever in the administration of this Indenture the Trustee shall deem it
desirable that a matter be proved or established prior to taking, suffering or omitting any
action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may,
in the absence of bad faith on its part, rely upon an Officers’ Certificate;

     (4) the Trustee may consult with counsel and the written advice of such counsel or any
Opinion of Counsel shall be full and complete authorization and

41

 

protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

     (5) the Trustee shall be under no obligation to exercise any of the rights or powers
vested in it by this Indenture at the request or direction of any of the Holders pursuant to
this Indenture, unless such Holders shall have offered to the Trustee reasonable security or
indemnity against the costs, expenses and liabilities which might be incurred by it in
compliance with such request or direction;

     (6) the Trustee shall not be bound to make any investigation into the facts or matters
stated in any resolution, certificate, statement, instrument, opinion, report, notice,
request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or
other paper or document, but the Trustee, in its discretion, may make such further inquiry
or investigation into such facts or matters as it may see fit, and, if the Trustee shall
determine to make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Company, personally or by agent or attorney; and

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

SECTION 604. Not Responsible for Recitals or Issuance of Securities.

     The recitals contained herein and in the Securities and the Subsidiary Guarantees, except the
Trustee’s certificates of authentication, shall be taken as the statements of the Company or the
Subsidiary Guarantors, as the case may be, and neither the Trustee nor any Authenticating Agent
assumes any responsibility for their correctness. The Trustee makes no representations as to the
validity or sufficiency of this Indenture or of the Securities or the Subsidiary Guarantees
endorsed thereon. Neither the Trustee nor any Authenticating Agent shall be accountable for the
use or application by the Company of Securities or the proceeds thereof.

SECTION 605. May Hold Securities.

     The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other
agent of the Company or any Subsidiary Guarantor, in its individual or any other capacity, may
become the owner or pledgee of Securities and, subject to Sections 608 and 613, may otherwise deal
with the Company and any Subsidiary Guarantor with the same rights it would have if it were not
Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent.

SECTION 606. Money Held in Trust.

     Money held by the Trustee in trust hereunder need not be segregated from other funds except to
the extent required by law. The Trustee shall be under no liability for interest on any money
received by it hereunder except as otherwise agreed with the Company or any Subsidiary Guarantor,
as the case may be.

42

 

SECTION 607. Compensation and Reimbursement.

     The Company and each Subsidiary Guarantor jointly and severally agree

     (1) to pay to the Trustee from time to time reasonable compensation for all services
rendered by it hereunder (which compensation shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust);

     (2) except as otherwise expressly provided herein, to reimburse the Trustee upon its
request for all reasonable expenses, disbursements and advances incurred or made by the
Trustee in accordance with any provision of this Indenture (including the reasonable
compensation and the expenses and disbursements of its agents and counsel), except any such
expense, disbursement or advance as may be attributable to its negligence or bad faith; and

     (3) to indemnify the Trustee for, and to hold it harmless against, any loss, liability
or expense incurred without negligence or bad faith on its part, arising out of or in
connection with the acceptance or administration of the trust or trusts hereunder, including
the costs and expenses of defending itself against any claim or liability in connection with
the exercise or performance of any of its powers or duties hereunder.

SECTION 608. Conflicting Interests.

     If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust
Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the
manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture.
To the extent permitted by such Act, the Trustee shall not be deemed to have a conflicting interest
by virtue of being a trustee under this Indenture with respect to Securities of more than one
series.

SECTION 609. Corporate Trustee Required; Eligibility.

     There shall at all times be one (and only one) Trustee hereunder with respect to the
Securities of each series, which may be Trustee hereunder for Securities of one or more other
series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act
as such, and has a combined capital and surplus of at least $50,000,000. If any such Person
publishes reports of condition at least annually, pursuant to law or to the requirements of its
supervising or examining authority, then for the purposes of this Section and to the extent
permitted by the Trust Indenture Act, the combined capital and surplus of such Person shall be
deemed to be its combined capital and surplus as set forth in its most recent report of condition
so published. If at any time the Trustee with respect to the Securities of any series shall cease
to be eligible in accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article.

43

 

SECTION 610. Resignation and Removal; Appointment of Successor.

     No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to
this Article shall become effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 611.

     The Trustee may resign at any time with respect to the Securities of one or more series by
giving written notice thereof to the Company. If the instrument of acceptance by a successor
Trustee required by Section 611 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the Securities of such
series.

     The Trustee may be removed at any time with respect to the Securities of any series by Act of
the Holders of a majority in principal amount of the Outstanding Securities of such series,
delivered to the Trustee and to the Company.

     If at any time:

     (1) the Trustee shall fail to comply with Section 608 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

     (2) the Trustee shall cease to be eligible under Section 609 and shall fail to resign
after written request therefor by the Company or by any such Holder, or

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

then, in any such case, (A) the Company by a Board Resolution may remove the Trustee with respect
to all Securities, or (B) subject to Section 514, any Holder who has been a bona fide Holder of a
Security for at least six months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

     If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall
occur in the office of Trustee for any cause, with respect to the Securities of one or more series,
the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with
respect to the Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of such series and
that at any time there shall be only one Trustee with respect to the Securities of any particular
series) and shall comply with the applicable requirements of Section 611. If, within one year
after such resignation, removal or incapability, or the occurrence of such vacancy, a successor
Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a
majority in principal amount of the Outstanding Securities of such series delivered to the Company
and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon

44

 

its acceptance of such appointment in accordance with the applicable requirements of Section
611, become the successor Trustee with respect to the Securities of such series and to that extent
supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to
the Securities of any series shall have been so appointed by the Company or the Holders and
accepted appointment in the manner required by Section 611, any Holder who has been a bona fide
Holder of a Security of such series for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the appointment of a
successor Trustee with respect to the Securities of such series.

     The Company shall give notice of each resignation and each removal of the Trustee with respect
to the Securities of any series and each appointment of a successor Trustee with respect to the
Securities of any series to all Holders of Securities of such series in the manner provided in
Section 106. Each notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office.

SECTION 611. Acceptance of Appointment by Successor.

     In case of the appointment hereunder of a successor Trustee with respect to all Securities,
every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company,
the Subsidiary Guarantors and to the retiring Trustee an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or
the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of
the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all
property and money held by such retiring Trustee hereunder.

     In case of the appointment hereunder of a successor Trustee with respect to the Securities of
one or more (but not all) series, the Company, the Subsidiary Guarantors, the retiring Trustee and
each successor Trustee with respect to the Securities of one or more series shall execute and
deliver an indenture supplemental hereto wherein each successor Trustee shall accept such
appointment and which (1) shall contain such provisions as shall be necessary or desirable to
transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and
duties of the retiring Trustee with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with
respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable
to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to
the Securities of that or those series as to which the retiring Trustee is not retiring shall
continue to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions
of this Indenture as shall be necessary to provide for or facilitate the administration of the
trusts hereunder by more than one Trustee, it being understood that nothing herein or in such
supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each
such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or
trusts hereunder administered by any other such Trustee; and upon the execution and delivery of
such supplemental indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee, without any further act,

45

 

deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which the appointment of
such successor Trustee relates; but, on request of the Company or any successor Trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

     Upon request of any such successor Trustee, the Company and the Subsidiary Guarantors shall
execute any and all instruments for more fully and certainly vesting in and confirming to such
successor Trustee all such rights, powers and trusts referred to in the first or second preceding
paragraph, as the case may be.

     No successor Trustee shall accept its appointment unless at the time of such acceptance such
successor Trustee shall be qualified and eligible under this Article.

SECTION 612. Merger, Conversion, Consolidation or Succession to Business.

     Any Person into which the Trustee may be merged or converted or with which it may be
consolidated, or any Person resulting from any merger, conversion or consolidation to which the
Trustee shall be a party, or any Person succeeding to all or substantially all the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder, provided such Person
shall be otherwise qualified and eligible under this Article, without the execution or filing of
any paper or any further act on the part of any of the parties hereto. As soon as practicable, the
successor Trustee shall mail a notice of its succession to the Company and the Holders of the
Securities then Outstanding. In case any Securities shall have been authenticated, but not
delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to
such authenticating Trustee may adopt such authentication and deliver the Securities so
authenticated with the same effect as if such successor Trustee had itself authenticated such
Securities.

SECTION 613. Preferential Collection of Claims Against Company and Subsidiary Guarantors.

     If and when the Trustee shall be or become a creditor of the Company, any Subsidiary Guarantor
or any other obligor upon the Securities, the Trustee shall be subject to the provisions of the
Trust Indenture Act regarding the collection of claims against the Company, such Subsidiary
Guarantor or any such other obligor.

SECTION 614. Appointment of Authenticating Agent.

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

46

 

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

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

     An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee
and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by
giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such
a notice of resignation or upon such a termination, or in case at any time such Authenticating
Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may
appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give
notice of such appointment in the manner provided in Section 106 to all Holders of Securities of
the series with respect to which such Authenticating Agent will serve. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the
rights, powers and duties of its predecessor hereunder, with like effect as if originally named as
an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible
under the provisions of this Section.

     The Trustee agrees to pay to each Authenticating Agent from time to time reasonable
compensation for its services under this Section, and the Trustee shall be entitled to be
reimbursed for such payments, subject to the provisions of Section 607.

     If an appointment with respect to one or more series is made pursuant to this Section, the
Securities of such series may have endorsed thereon, in addition to the Trustee’s certificate of
authentication, an alternative certificate of authentication in the following form:

47

 

     This is one of the Securities of the series designated therein referred to in the
within-mentioned Indenture.

SECTION 902. Supplemental Indentures With Consent of Holders.

     With the consent of the Holders of not less than a majority in principal amount of the

affected thereby:

     (1) change the Stated Maturity of the principal of, or any installment of principal of
or interest on, any Security, or reduce the principal amount thereof or the rate of interest

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.

53

 

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

SECTION 903. Execution of Supplemental Indentures.

     In executing, or accepting the additional trusts created by, any supplemental indenture

under this Indenture or otherwise.

of the Trustee and the Company, to any such supplemental indenture may be prepared and executed by
the Company, if applicable the Subsidiary Guarantees may be endorsed thereon and such new
Securities may be authenticated and delivered by the Trustee in exchange for Outstanding Securities
of such series.

ARTICLE TEN

COVENANTS

SECTION 1001. Payment of Principal, Premium and Interest.

     The Company covenants and agrees for the benefit of each series of Securities that it will
duly and punctually pay the principal of and any premium and interest on the Securities of that
series in accordance with the terms of the Securities and this Indenture. Principal, premium, if
any, and interest shall be considered paid on the date due if the Paying Agent, if other than the

54

 

Company or a Subsidiary thereof, holds as of 11:00 A.M., New York City time, on the due date
money deposited by the Company in immediately available funds and designated for and sufficient to
pay all principal, premium, if any, and interest then due.

SECTION 1002. Maintenance of Office or Agency.

     The Company will maintain in each Place of Payment for any series of Securities an office or
agency where Securities of that series may be presented or surrendered for payment or, if
applicable, for conversion, where Securities of that series may be surrendered for registration of
transfer or exchange and where notices and demands to or upon the Company or any Subsidiary
Guarantor in respect of the Securities of that series or any Subsidiary Guarantee and this
Indenture may be served. 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 and each Subsidiary Guarantor hereby
appoints the Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

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

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

     If the Company or any Subsidiary Guarantor shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the principal of or any
premium or interest on any of the Securities of that series, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum sufficient to pay the principal and any premium and
interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as
herein provided and will promptly notify the Trustee of its action or failure so to act.

     Whenever the Company shall have one or more Paying Agents for any series of Securities, it
will, prior to 11:00 A.M., New York City time, on each due date of the principal of or any premium
or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay
such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to
act.

     The Company will cause each Paying Agent for any series of Securities other than the Trustee
to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the
Trustee, subject to the provisions of this Section, that such Paying Agent will (1)

55

 

comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and
(2) during the continuance of any default by the Company, the Subsidiary Guarantors, if applicable,
or any other obligor upon the Securities of that series in the making of any payment in respect of
the Securities of that series, upon the written request of the Trustee, forthwith pay to the
Trustee all sums held in trust by such Paying Agent for payment in respect of the Securities of
that series.

     The Company may at any time, for the purpose of obtaining the satisfaction and discharge of
this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay,
to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by
the Trustee upon the same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be
released from all further liability with respect to such money.

     Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of or any premium or interest on any Security of any series
and remaining unclaimed for two years after such principal, premium or interest has become due and
payable shall be paid to the Company on Company Request, or (if then held by the Company) 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 thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before
being required to make any such repayment, may at the expense of the Company cause to be published
once, in a newspaper published in the English language, customarily published on each Business Day
and of general circulation in The City of New York, New York, notice that such money remains
unclaimed and that, after a date specified therein, which shall not be less than 30 days from the
date of such publication, any unclaimed balance of such money then remaining will be repaid to the
Company.

SECTION 1004. Statement by Officers as to Default.

     (a) The Company and the Subsidiary Guarantors will deliver to the Trustee, within 90 days
after the end of each fiscal year of the Company ending after the date hereof, an Officers’
Certificate, stating whether or not to the best knowledge of the signers thereof the Company or any
Subsidiary Guarantor, as the case may be, is in default in the performance and observance of any of
the terms, provisions and conditions of this Indenture (without regard to any period of grace or
requirement of notice provided hereunder) and, if the Company or any Subsidiary Guarantor shall be
in default, specifying all such defaults and the nature and status thereof of which they may have
knowledge.

     (b) The Company and each Subsidiary Guarantor shall deliver to the Trustee, as soon as
possible and in any event within five days after the Company or such Subsidiary Guarantor becomes
aware or should reasonably become aware of the occurrence of an Event of Default or an event which,
with notice or the lapse of time or both, would constitute an Event of Default, an Officers’
Certificate setting forth the details of such Event of Default or default, and the action which the
Company or such Subsidiary Guarantor proposes to take with respect thereto.

56

 

SECTION 1005. Existence.

     Subject to Article Eight, the Company will do or cause to be done all things necessary to
preserve and keep in full force and effect the existence, rights (charter and statutory) and
franchises of the Company; provided, however, that the Company shall not be required to preserve
any such right or franchise if it shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company and that the loss thereof is not
disadvantageous in any material respect to the Holders.

SECTION 1006. Maintenance of Properties.

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

SECTION 1007. Payment of Taxes and Other Claims.

     The Company will pay or discharge or cause to be paid or discharged, before the same shall
become delinquent, (1) all taxes, assessments and governmental charges levied or imposed upon the
Company or any Subsidiary or upon the income, profits or property of the Company or any Subsidiary,
and (2) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a
lien upon the property of the Company or any Subsidiary; provided, however, that the Company shall
not be required to pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim whose amount, applicability or validity is being contested in good faith by
appropriate proceedings.

SECTION 1008. Maintenance of Insurance.

     The Company shall, and shall cause its Subsidiaries to, keep at all times all of their
properties which are of an insurable nature insured against loss or damage with insurers believed
by the Company to be responsible to the extent that property of similar character is usually so
insured by corporations similarly situated and owning like properties in accordance with good
business practice.

SECTION 1009. Waiver of Certain Covenants.

     Except as otherwise specified as contemplated by Section 301 for Securities of such series,
the Company may, with respect to the Securities of any series, omit in any particular instance to
comply with any term, provision or condition set forth in any of Sections 1005 through 1008 or in
any covenant provided pursuant to Section 301(19), 901(2) or 901(7) for the benefit of the Holders
of such series if before the time for such compliance the Holders of at least

57

 

a majority in principal amount of the Outstanding Securities of such series shall, by Act of
such Holders, either waive such compliance in such instance or generally waive compliance with such
term, provision or condition, but no such waiver shall extend to or affect such term, provision or
condition except to the extent so expressly waived, and, until such waiver shall become effective,
the obligations of the Company and the duties of the Trustee in respect of any such term, provision
or condition shall remain in full force and effect.

ARTICLE ELEVEN

REDEMPTION OF SECURITIES

SECTION 1101. Applicability of Article.

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

SECTION 1102. Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Securities shall be evidenced by a Board Resolution
or in another manner specified as contemplated by Section 301 for such Securities. In case of any
redemption at the election of the Company of less than all the Securities of any series (including
any such redemption affecting only a single Security), the Company shall, at least five Business
Days prior to giving notice of such redemption (unless a shorter notice shall be satisfactory to
the Trustee), notify the Trustee of such Redemption Date, of the principal amount of Securities of
such series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed. In
the case of any redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company
shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such
restriction.

SECTION 1103. Selection by Trustee of Securities to Be Redeemed.

     If less than all the Securities of any series are to be redeemed (unless all the Securities of
such series and of a specified tenor are to be redeemed or unless such redemption affects only a
single Security), the particular Securities to be redeemed shall be selected by the Trustee, from
the Outstanding Securities of such series not previously called for redemption, (i) in compliance
with the requirements of the principal national securities exchange on which such Securities are
listed, if such Securities are listed on any national securities exchange, and (ii) if such
Securities are not so listed, on a pro rata basis, by lot or by such other method as the Trustee
shall deem fair and appropriate and which may provide for the selection for redemption of a portion
of the principal amount of any Security of such series, provided that the unredeemed portion of the
principal amount of any Security shall be in an authorized denomination (which shall not be less
than the minimum authorized denomination) for such Security. If less than all the Securities of
such series and of a specified tenor are to be redeemed (unless such redemption affects only a
single Security), the particular Securities to be redeemed shall be selected by the Trustee, from

58

 

the Outstanding Securities of such series and specified tenor not previously called for
redemption in accordance with the preceding sentence.

     The Trustee shall promptly notify the Company in writing of the Securities selected for
redemption as aforesaid and, in case of any Securities selected for partial redemption as
aforesaid, the principal amount thereof to be redeemed.

     The provisions of the two preceding paragraphs shall not apply with respect to any redemption
affecting only a single Security, whether such Security is to be redeemed in whole or in part. In
the case of any such redemption in part, the unredeemed portion of the principal amount of the
Security shall be in an authorized denomination (which shall not be less than the minimum
authorized denomination) for such Security.

     For all purposes of this Indenture, unless the context otherwise requires, all provisions
relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to
be redeemed only in part, to the portion of the principal amount of such Securities which has been
or is to be redeemed. If any Security selected for partial redemption is surrendered for
conversion after such selection, the converted portion of such Security shall be deemed (so far as
may be) to be the portion selected for redemption. Upon any redemption of less than all the
Securities of a series, for purposes of selection for redemption the Company and the Trustee may
treat as Outstanding Securities surrendered for conversion during the period of 15 days next
preceding the mailing of a notice of redemption, and need not treat as Outstanding any Security
authenticated and delivered during such period in exchange for the unconverted portion of any
Security converted in part during such period.

SECTION 1104. Notice of Redemption.

     Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than
30 nor more than 60 days prior to the Redemption Date (except that redemption notices may be mailed
more than 60 days prior to a Redemption Date if the notice is issued in connection with a
satisfaction and discharge pursuant to Article Four, a Defeasance or a Covenant Defeasance), to
each Holder of Securities to be redeemed, at his address appearing in the Security Register;
provided, however, notice of redemption may be given more than 60 days prior to the Redemption Date
if the notice is issued in connection with a satisfaction and discharge pursuant to Article Four.

     All notices of redemption shall state:

     (1) the Redemption Date,

     (2) the Redemption Price, if then determinable and otherwise the method of its
determination,

     (3) if less than all the Outstanding Securities of any series consisting of more than a
single Security are to be redeemed, the identification (and, in the case of partial
redemption of any such Securities, the principal amounts) of the particular Securities to be
redeemed and, if less than all the Outstanding Securities of any series consisting of a

59

 

single Security are to be redeemed, the principal amount of the particular Security to
be redeemed,

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

     (5) the place or places where each such Security is to be surrendered for payment of
the Redemption Price,

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

     (7) if applicable, the conversion price then in effect and the date on which the right
to convert such Securities will expire.

     Notice of redemption of Securities to be redeemed at the election of the Company shall be
given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of
the Company and shall be irrevocable. If any Security called for redemption is converted pursuant
hereto, any money deposited with the Trustee or any Paying Agent or so segregated and held in trust
for the redemption of such Security shall be paid to the Company upon delivery of a Company Request
to the Trustee or such Paying Agent, or, if then held by the Company, shall be discharged from such
trust.

SECTION 1105. Deposit of Redemption Price.

     Prior to 11:00 A.M., New York City time, on any Redemption Date, the Company shall deposit
with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the
Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued
interest on, all the Securities which are to be redeemed on that date.

SECTION 1106. Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall,
on the Redemption Date, become due and payable at the Redemption Price therein specified, and from
and after such date (unless the Company shall default in the payment of the Redemption Price and
accrued interest) such Securities shall cease to bear interest. Upon surrender of any such
Security for redemption in accordance with said notice, such Security shall be paid by the Company
at the Redemption Price, together with accrued interest to the Redemption Date; provided, however,
that, unless otherwise specified as contemplated by Section 301, installments of interest whose
Stated Maturity is on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the close of business on
the relevant Record Dates according to their terms and the provisions of Section 307.

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

60

 

SECTION 1107. Securities Redeemed in Part.

     Any Security which is to be redeemed only in part shall be surrendered at a Place of Payment
therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the
Holder thereof or his attorney duly authorized in writing), and the Company shall execute, if
applicable to Subsidiary Guarantors shall execute the Subsidiary Guarantee endorsed thereon, and
the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a
new Security or Securities of the same series and of like tenor, of any authorized denomination as
requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed
portion of the principal of the Security so surrendered.

[INTENTIONALLY OMITTED]

ARTICLE THIRTEEN

SUBSIDIARY GUARANTEES

SECTION 1301. Applicability of Article.

     If the Company elects to issue any series of Securities with the benefit of Subsidiary
Guarantees, such election shall be evidenced in or pursuant to the Board Resolution or supplemental
indenture establishing such series of Securities pursuant to Section 301 and the provisions of this
Article shall be applicable to each such series of Securities except as otherwise specified in or
pursuant to the Board Resolution or supplemental indenture establishing such series pursuant to
Section 301.

SECTION 1302. Subsidiary Guarantees.

     Subject to Section 1301, each Subsidiary Guarantor hereby, jointly and severally, fully and
unconditionally guarantees to each Holder of a Security authenticated and delivered by the Trustee,
the due and punctual payment of the principal of (and premium, if any) and interest on such
Security when and as the same shall become due and payable, whether at the Stated Maturity, by
acceleration, call for redemption, offer to purchase or otherwise, in accordance with the terms of
such Security and of this Indenture, and each Subsidiary Guarantor similarly guarantees to the
Trustee the payment of all amounts owing to the Trustee in accordance with the terms of this
Indenture. In case of the failure of the Company punctually to make any such payment, each
Subsidiary Guarantor hereby, jointly and severally, agrees to cause such payment to be made
punctually when and as the same shall become due and payable, whether at the Stated Maturity or by
acceleration, call for redemption, offer to purchase or otherwise, and as if such payment were made
by the Company.

     Each of the Subsidiary Guarantors hereby jointly and severally agrees that its obligations
hereunder shall be absolute, unconditional, irrespective of, and shall be unaffected by, the

61

 

validity, regularity or enforceability of such Security or this Indenture, the absence of any
action to enforce the same or any release, amendment, waiver or indulgence granted to the Company
or any guarantor or any consent to departure from any requirement of any other guarantee of all or
any of the Securities of such series or any other circumstances which might otherwise constitute a
legal or equitable discharge or defense of a surety or guarantor; provided, however, that,
notwithstanding the foregoing, no such release, amendment, waiver or indulgence shall, without the
consent of such Subsidiary Guarantor, increase the principal amount of such Security, or increase
the interest rate thereon, or alter the Stated Maturity thereof. Each of the Subsidiary Guarantors
hereby waives the benefits of diligence, presentment, demand for payment, any requirement that the
Trustee or any of the Holders protect, secure, perfect or insure any security interest in or other
lien on any property subject thereto or exhaust any right or take any action against the Company or
any other Person or any collateral, filing of claims with a court in the event of insolvency or
bankruptcy of the Company, any right to require a proceeding first against the Company, protest or
notice with respect to such Security or the indebtedness evidenced thereby and all demands
whatsoever, and covenants that this Subsidiary Guarantee will not be discharged in respect of such
Security except by complete performance of the obligations contained in such Security and in such
Subsidiary Guarantee. Each Subsidiary Guarantor agrees that if, after the occurrence and during
the continuance of an Event of Default, the Trustee or any of the Holders are prevented by
applicable law from exercising their respective rights to accelerate the maturity of the Securities
of a series, to collect interest on the Securities of a series, or to enforce or exercise any other
right or remedy with respect to the Securities of a series, such Subsidiary Guarantor agrees to pay
to the Trustee for the account of the Holders, upon demand therefor, the amount that would
otherwise have been due and payable had such rights and remedies been permitted to be exercised by
the Trustee or any of the Holders.

     Each Subsidiary Guarantor shall be subrogated to all rights of the Holders of the Securities
upon which its Subsidiary Guarantee is endorsed against the Company in respect of any amounts paid
by such Subsidiary Guarantor on account of such Security pursuant to the provisions of its
Subsidiary Guarantee or this Indenture; provided, however, that no Subsidiary Guarantor shall be
entitled to enforce or to receive any payments arising out of, or based upon, such right of
subrogation until the principal of (and premium, if any) and interest on all Securities of the
relevant series issued hereunder shall have been paid in full.

     Each Subsidiary Guarantor that makes or is required to make any payment in respect of its
Subsidiary Guarantee shall be entitled to seek contribution from the other Subsidiary Guarantors to
the extent permitted by applicable law; provided, however, that no Subsidiary Guarantor shall be
entitled to enforce or receive any payments arising out of, or based upon, such right of
contribution until the principal of (and premium, if any) and interest on all Securities of the
relevant series issued hereunder shall have been paid in full.

     Each Subsidiary Guarantee shall remain in full force and effect and continue to be effective
should any petition be filed by or against the Company for liquidation or reorganization, should
the Company become insolvent or make an assignment for the benefit of creditors or should a
receiver or trustee be appointed for all or any part of the Company’s assets, and shall, to the
fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if
at any time payment and performance of the Securities of a series, is, pursuant to applicable law,
rescinded or reduced in amount, or must otherwise be restored or returned by any

62

 

Holder of the Securities, whether as a “voidable preference”, “fraudulent transfer”, or
otherwise, all as though such payment or performance had not been made. In the event that any
payment, or any part thereof, is rescinded, reduced, restored or returned, the Securities shall, to
the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and
not so rescinded, reduced, restored or returned.

SECTION 1303. Execution and Delivery of Subsidiary Guarantees.

     The Subsidiary Guarantees to be endorsed on the Securities shall include the terms of the
Subsidiary Guarantee set forth in Section 1302 and any other terms that may be set forth in the
form established pursuant to Section 204. Subject to Section 1301, each of the Subsidiary
Guarantors hereby agrees to execute its Subsidiary Guarantee, in a form established pursuant to
Section 204, to be endorsed on each Security authenticated and delivered by the Trustee.

     The Subsidiary Guarantee shall be executed on behalf of each respective Subsidiary Guarantor
by any one of such Subsidiary Guarantor’s Chairman of the Board of Directors, Vice Chairman of the
Board of Directors, Chief Executive Officer, President, one of its Vice Presidents, or its
Secretary. The signature of any or all of these persons on the Subsidiary Guarantee may be manual
or facsimile.

     A Subsidiary Guarantee bearing the manual or facsimile signature of individuals who were at
any time the proper officers of a Subsidiary Guarantor shall bind such Subsidiary Guarantor,
notwithstanding that such individuals or any of them have ceased to hold such offices prior to the
authentication and delivery of the Security on which such Subsidiary Guarantee is endorsed or did
not hold such offices at the date of such Subsidiary Guarantee.

     The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall
constitute due delivery of the Subsidiary Guarantee endorsed thereon on behalf of the Subsidiary
Guarantors and shall bind each Subsidiary Guarantor notwithstanding the fact that Subsidiary
Guarantee does not bear the signature of such Subsidiary Guarantor. Each of the Subsidiary
Guarantors hereby jointly and severally agrees that its Subsidiary Guarantee set forth in Section
1302 and in the form of Subsidiary Guarantee established pursuant to Section 204 shall remain in
full force and effect notwithstanding any failure to endorse a Subsidiary Guarantee on any
Security.

SECTION 1304. Release of Subsidiary Guarantors.

     Unless otherwise specified pursuant to Section 301 with respect to a series of Securities,
each Subsidiary Guarantee will remain in effect with respect to the respective Subsidiary Guarantor
until the entire principal of, premium, if any, and interest on the Securities to which such
Subsidiary Guarantee relates shall have been paid in full or otherwise satisfied and discharged in
accordance with the provisions of such Securities and this Indenture and all amounts owing to the
Trustee hereunder have been paid; provided, however, that if (i) such Subsidiary Guarantor ceases
to be a Subsidiary in compliance with the applicable provisions of this Indenture, (ii) either
Defeasance or Covenant Defeasance occurs with respect to such Securities pursuant to Article
Fifteen or (iii) all or substantially all of the assets of such Subsidiary Guarantor or all of the
Capital Stock of such Subsidiary Guarantor is sold (including

63

 

by sale, merger, consolidation or otherwise) by the Company or any Subsidiary in a transaction
complying with the requirements of this Indenture, then, in each case of (i), (ii) or (iii), upon
delivery by the Company of an Officers’ Certificate and an Opinion of Counsel stating that all
conditions precedent herein provided for relating to the release of such Subsidiary Guarantor from
its obligations under its Subsidiary Guarantee and this Article Thirteen have been complied with,
such Subsidiary Guarantor shall be released and discharged of its obligations under its Subsidiary
Guarantee and under this Article Thirteen without any action on the part of the Trustee or any
Holder, and the Trustee shall execute any documents reasonably required in order to acknowledge the
release of such Subsidiary Guarantor from its obligations under its Subsidiary Guarantee endorsed
on the Securities of such series and under this Article Thirteen.

SECTION 1305. Additional Subsidiary Guarantors.

     If so specified pursuant to Section 301 with respect to a series of Securities, the Company
will cause any domestic Subsidiary of the Company that becomes a Subsidiary after the date the
Securities of a series are first issued hereunder to become a Subsidiary Guarantor as soon as
practicable after such Subsidiary becomes a Subsidiary. The Company shall cause any such
Subsidiary to become a Subsidiary Guarantor with respect to the Securities by executing and
delivering to the Trustee (a) a supplemental indenture, in form and substance satisfactory to the
Trustee, which subjects such Person to the provisions (including the representations and
warranties) of this Indenture as a Subsidiary Guarantor and (b) an Opinion of Counsel to the effect
that such supplemental indenture has been duly authorized and executed by such Person and such
supplemental indenture and such Person’s obligations under its Subsidiary Guarantee and this
Indenture constitute the legal, valid, binding and enforceable obligations of such Person (subject
to such customary exceptions concerning creditors’ rights and equitable principles as may be
acceptable to the Trustee in its discretion).

SECTION 1306. Limitation on Liability.

     Any term or provision of this Indenture to the contrary notwithstanding, the maximum amount of
the Subsidiary Guarantee of any Subsidiary Guarantor shall not exceed the maximum amount that can
be hereby guaranteed by such Subsidiary Guarantor without rendering such Subsidiary Guarantee
voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar
laws affecting the rights of creditors generally.

ARTICLE FOURTEEN

[INTENTIONALLY OMITTED]

ARTICLE FIFTEEN

DEFEASANCE AND COVENANT DEFEASANCE

SECTION 1501. Company’s Option to Effect Defeasance or Covenant Defeasance.

     The Company may elect, at its option at any time, to have Section 1502 or Section 1503 applied
to any Securities or any series of Securities, as the case may be, designated pursuant to Section
301 as being defeasible pursuant to such Section 1502 or 1503, in accordance with any applicable
requirements provided pursuant to Section 301 and upon compliance with the conditions set forth
below in this Article. Any such election shall be evidenced in or pursuant to a Board Resolution
or in another manner specified as contemplated by Section 301 for such Securities.

SECTION 1502. Defeasance and Discharge.

     Upon the Company’s exercise of its option (if any) to have this Section applied to any
Securities or any series of Securities, as the case may be, the Company shall be deemed to have
been discharged from its obligations, and each Subsidiary Guarantor shall be deemed to have been
discharged from its obligations with respect to its Subsidiary Guarantees of such Securities, as
provided in this Section on and after the date the conditions set forth in Section 1504 are
satisfied (herein called “Defeasance”). For this purpose, such Defeasance means that the Company
shall be deemed to have paid and discharged the entire indebtedness represented by such Securities
and to have satisfied all its other obligations under such Securities and this Indenture insofar as
such Securities are concerned (and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging the same), subject to the following which shall survive until otherwise
terminated or discharged hereunder: (1) the rights of Holders of such Securities to receive, solely
from the trust fund described in Section 1504 and as more fully set forth in such Section, payments
in respect of the principal of and any premium and interest on such Securities when payments are
due, or, if applicable, to convert such Securities in accordance with their terms, (2) the
Company’s and each Subsidiary Guarantor’s obligations with respect to such Securities under
Sections 304, 305, 306, 1002 and 1003, and, if applicable, their obligations with respect to the
conversion of such Securities, (3) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and (4) this Article. Subject to compliance with this Article, the Company may exercise
its option (if any) to have this Section applied to any Securities notwithstanding the prior
exercise of its option (if any) to have Section 1503 applied to such Securities.

SECTION 1503. Covenant Defeasance.

     Upon the Company’s exercise of its option (if any) to have this Section applied to any
Securities or any series of Securities, as the case may be, (1) the Company shall be released from
its obligations under Section 801(3), Sections 1006 through 1008, inclusive, and any covenants

65

 

provided pursuant to Section 301(19), 901(2) or 901(7) for the benefit of the Holders of such
Securities, and (2) the occurrence of any event specified in Sections 501(5) (with respect to any
of Section 801(3), Sections 1006 through 1008, inclusive, and any such covenants provided pursuant
to Section 301(19), 901(2) or 901(7)), 501(6), 501(7), but only insofar as Sections 501(6) and
501(7) relate to Subsidiary Guarantors, 501(8) and 501(9) shall be deemed not to be or result in an
Event of Default and (3) the provisions of Article Thirteen shall cease to be effective, in each
case with respect to such Securities and Subsidiary Guarantees as provided in this Section on and
after the date the conditions set forth in Section 1504 are satisfied (herein called “Covenant
Defeasance”). For this purpose, such Covenant Defeasance means that, with respect to such
Securities, the Company and the Subsidiary Guarantors, as applicable, may omit to comply with and
shall have no liability in respect of any term, condition or limitation set forth in any such
specified Section (to the extent so specified in the case of Section 501(5)) or Article Thirteen,
whether directly or indirectly by reason of any reference elsewhere herein to any such Section or
Article or by reason of any reference in any such Section or Article to any other provision herein
or in any other document, but the remainder of this Indenture and such Securities shall be
unaffected thereby.

SECTION 1504. Conditions to Defeasance or Covenant Defeasance.

     The following shall be the conditions to the application of Section 1502 or Section 1503 to
any Securities or any series of Securities, as the case may be:

     (1) The Company shall irrevocably have deposited or caused to be deposited with the
Trustee (or another trustee which satisfies the requirements contemplated by Section 609 and
agrees to comply with the provisions of this Article applicable to it) as trust funds in
trust for the purpose of making the following payments, specifically pledged as security
for, and dedicated solely to, the benefits of the Holders of such Securities, (A) money in
an amount, or (B) U.S. Government Obligations which through the scheduled payment of
principal and interest in respect thereof in accordance with their terms will provide, not
later than one day before the due date of any payment, money in an amount, or (C) a
combination thereof, in each case sufficient, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof delivered to
the Trustee, to pay and discharge, and which shall be applied by the Trustee (or any such
other qualifying trustee) to pay and discharge, the principal of and any premium and
interest on such Securities on the respective Stated Maturities, in accordance with the
terms of this Indenture and such Securities. As used herein, “U.S. Government Obligation”
means (x) any security which is (i) a direct obligation of the United States of America for
the payment of which the full faith and credit of the United States of America is pledged or
(ii) an obligation of a Person controlled or supervised by and acting as an agency or
instrumentality of the United States of America the payment of which is unconditionally
guaranteed as a full faith and credit obligation by the United States of America, which, in
either case (i) or (ii), is not callable or redeemable at the option of the issuer thereof,
and (y) any depositary receipt issued by a bank (as defined in Section 3(a)(2) of the
Securities Act) as custodian with respect to any U.S. Government Obligation which is
specified in clause (x) above and held by such bank for the account of the holder of such
depositary receipt, or with respect to any specific payment of principal of or interest on
any U.S. Government Obligation

66

 

which is so specified and held, provided that (except as required by law) such
custodian is not authorized to make any deduction from the amount payable to the holder of
such depositary receipt from any amount received by the custodian in respect of the U.S.
Government Obligation or the specific payment of principal or interest evidenced by such
depositary receipt.

     (2) In the event of an election to have Section 1502 apply to any Securities or any
series of Securities, as the case may be, the Company shall have delivered to the Trustee an
Opinion of Counsel stating that (A) the Company has received from, or there has been
published by, the Internal Revenue Service a ruling or (B) since the date of this
instrument, there has been a change in the applicable Federal income tax law, in either case
(A) or (B) to the effect that, and based thereon such opinion shall confirm that, the
Holders of such Securities will not recognize gain or loss for Federal income tax purposes
as a result of the deposit, Defeasance and discharge to be effected with respect to such
Securities and will be subject to Federal income tax on the same amount, in the same manner
and at the same times as would be the case if such deposit, Defeasance and discharge were
not to occur.

     (3) In the event of an election to have Section 1503 apply to any Securities or any
series of Securities, as the case may be, the Company shall have delivered to the Trustee an
Opinion of Counsel to the effect that the Holders of such Securities will not recognize gain
or loss for Federal income tax purposes as a result of the deposit and Covenant Defeasance
to be effected with respect to such Securities and will be subject to Federal income tax on
the same amount, in the same manner and at the same times as would be the case if such
deposit and Covenant Defeasance were not to occur.

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

     (5) No event which is, or after notice or lapse of time or both would become, an Event
of Default with respect to such Securities or any other Securities shall have occurred and
be continuing at the time of such deposit or, with regard to any such event specified in
Sections 501(6) and (7), at any time on or prior to the 121st day after the date of such
deposit (it being understood that this condition shall not be deemed satisfied until after
such 121st day).

     (6) Such Defeasance or Covenant Defeasance shall not cause the Trustee to have a
conflicting interest within the meaning of the Trust Indenture Act (assuming all Securities
are in default within the meaning of such Act).

     (7) Such Defeasance or Covenant Defeasance shall not result in a breach or violation
of, or constitute a default under, any agreement or instrument (other than this Indenture)
to which the Company or any Subsidiary is a party or by which it is bound.

67

 

     (8) The Company shall have delivered to the Trustee an Opinion of Counsel to the effect
that such deposit shall not cause either the Trustee or the trust so created to be subject
to the Investment Company Act of 1940.

     (9) The Company shall have delivered to the Trustee an Officers’ Certificate and an
Opinion of Counsel, each stating that all conditions precedent with respect to such
Defeasance or Covenant Defeasance have been complied with.

SECTION 1505. Deposited Money and U.S. Government Obligations to Be Held in Trust; Miscellaneous
Provisions.

     Subject to the provisions of the last paragraph of Section 1003, all money and U.S. Government
Obligations (including the proceeds thereof) deposited with the Trustee or other qualifying trustee
(solely for purposes of this Section and Section 1506, the Trustee and any such other trustee are
referred to collectively as the “Trustee”) pursuant to Section 1504 in respect of any Securities
shall be held in trust and applied by the Trustee, in accordance with the provisions of such
Securities and this Indenture, to the payment, either directly or through any such Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders
of such Securities, of all sums due and to become due thereon in respect of principal and any
premium and interest, but money so held in trust need not be segregated from other funds except to
the extent required by law.

     The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed
on or assessed against the U.S. Government Obligations deposited pursuant to Section 1504 or the
principal and interest received in respect thereof other than any such tax, fee or other charge
which by law is for the account of the Holders of Outstanding Securities.

     Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to
the Company from time to time upon Company Request any money or U.S. Government Obligations held by
it as provided in Section 1504 with respect to any Securities which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then be required to be
deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to such
Securities.

SECTION 1506. Reinstatement.

     If the Trustee or the Paying Agent is unable to apply any money in accordance with this
Article with respect to any Securities by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such application, then the
obligations under this Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 1502 or 1503 shall be revived and reinstated as though no deposit had
occurred pursuant to this Article with respect to such Securities, until such time as the Trustee
or Paying Agent is permitted to apply all money held in trust pursuant to Section 1505 with respect
to such Securities in accordance with this Article; provided, however, that if the Company makes
any payment of principal of or any premium or interest on any such Security following such
reinstatement of its obligations, the Company shall be subrogated to the

68

 

rights (if any) of the Holders of such Securities to receive such payment from the money so
held in trust.

ARTICLE SIXTEEN

SINKING FUNDS

SECTION 1601. Applicability of Article.

     The provisions of this Article shall be applicable to any sinking fund for the retirement of
Securities of any series except as otherwise specified as contemplated by Section 301 for such
Securities.

     The minimum amount of any sinking fund payment provided for by the terms of any Securities 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 such Securities is herein referred to as an “optional sinking
fund payment”. If provided for by the terms of any Securities, the cash amount of any sinking fund
payment may be subject to reduction as provided in Section 1602. Each sinking fund payment shall
be applied to the redemption of Securities as provided for by the terms of such Securities.

SECTION 1602. Satisfaction of Sinking Fund Payments with Securities.

     The Company (1) may deliver Outstanding Securities of a series (other than any previously
called for redemption) and (2) may apply as a credit Securities of a series which have been (x)
converted or (y) redeemed either at the election of the Company pursuant to the terms of such
Securities or through the application of permitted optional sinking fund payments pursuant to the
terms of such Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to any Securities of such series required to be made pursuant to the terms of
such Securities as and to the extent provided for by the terms of such Securities; provided,
however, that the Securities to be so credited have not been previously so credited. The
Securities to be so credited shall be received and credited for such purpose by the Trustee at the
Redemption Price, as specified in the Securities so to be redeemed, for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall be reduced
accordingly.

SECTION 1603. Redemption of Securities for Sinking Fund.

     Not less than 35 days prior to each sinking fund payment date for any Securities, the Company
will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing
sinking fund payment for such Securities pursuant to the terms of such Securities, the portion
thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which
is to be satisfied by delivering and crediting Securities pursuant to Section 1602 and will also
deliver to the Trustee any Securities to be so delivered. Not less than 32 days prior to each such
sinking fund payment date, the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 1103 and cause notice of the redemption
thereof to be given in the name of and at the expense of the Company in the manner

69

 

provided in Section 1104. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections 1106 and 1107.

     This instrument may be executed in any number of counterparts, each of which so executed shall
be deemed to be an original, but all such counterparts shall together constitute but one and the
same instrument.

SECTION 104. Acts of Holders; Record Dates.

     Whenever in this Indenture it is provided that the Holders of a specified percentage in
aggregate principal amount of the Securities of any or all series may take action (including the
making of any demand or request, the giving of any direction, 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 have joined therein may be evidenced (a) by any instrument or any number of
instruments of similar tenor executed by Holders in person or by agent or proxy appointed in
writing, (b) by the record of the Holders voting in favor thereof at any meeting of Holders duly
called and held in accordance with procedures approved by the Trustee, (c) by a combination of such
instrument or instruments and any such record of such a meeting of Holders or (d) in the case of
Securities evidenced by a Global Security, by any electronic transmission or other message, whether
or not in written format, that complies with the Depositary’s applicable procedures. Such evidence
(and the action embodied therein and evidenced thereby) are herein sometimes referred to as the
“Act” of the relevant Holders. Proof of execution of any such instrument or of a writing
appointing any such agent or proxy shall be sufficient for any purpose of this Indenture and
(subject to Section 601) conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Section.

     The fact and date of the execution by any Person of any such instrument or writing may be
proved by the affidavit of a witness of such execution or by a certificate of a notary public or
other officer authorized by law to take acknowledgments of deeds, certifying that the individual
signing such instrument or writing acknowledged to him the execution thereof. Where such execution
is by a signer acting in a capacity other than his individual capacity, such certificate or
affidavit shall also constitute sufficient proof of his authority. The fact and date of the
execution of any such instrument or writing, or the authority of the Person executing the same, may
also be proved in any other manner that the Trustee deems sufficient.

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

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

     The Company may set any day as a record date for the purpose of determining the Holders of
Outstanding Securities of any series entitled to give, make or take any request, demand,
authorization, direction, notice, consent, waiver or other action provided or permitted by this
Indenture to be given, made or taken by Holders of Securities of such series, provided that the
Company may not set a record date for, and the provisions of this paragraph shall not apply with
respect to, the giving or making of any notice, declaration, request or direction referred to in
the next paragraph. If any record date is set pursuant to this paragraph, the Holders of
Outstanding Securities of the relevant series on such record date, and no other Holders, shall be
entitled to take the relevant action, whether or not such Holders remain Holders after such record
date; provided that no such action shall be effective hereunder unless taken on or prior to the
applicable Expiration Date by Holders of the requisite principal amount of Outstanding

9

 

Securities of such series on such record date. Nothing in this paragraph shall be construed
to prevent the Company from setting a new record date for any action for which a record date has
previously been set pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be cancelled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders of the requisite
principal amount of Outstanding Securities of the relevant series on the date such action is taken.
Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense,
shall cause notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the
relevant series in the manner set forth in Section 106.

     The Trustee may set any day as a record date for the purpose of determining the Holders of
Outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of
Default, (ii) any declaration of acceleration referred to in Section 502, (iii) any request to
institute proceedings referred to in Section 507(2) or (iv) any direction referred to in Section
512, in each case with respect to Securities of such series. If any record date is set pursuant to
this paragraph, the Holders of Outstanding Securities of such series on such record date, and no
other Holders, shall be entitled to join in such notice, declaration, request or direction, whether
or not such Holders remain Holders after such record date; provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the
requisite principal amount of Outstanding Securities of such series on such record date. Nothing
in this paragraph shall be construed to prevent the Trustee from setting a new record date for any
action for which a record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person be cancelled and of
no effect), and nothing in this paragraph shall be construed to render ineffective any action taken
by Holders of the requisite principal amount of Outstanding Securities of the relevant series on
the date such action is taken. Promptly after any record date is set pursuant to this paragraph,
the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action
by Holders and the applicable Expiration Date to be given to the Company in writing and to each
Holder of Securities of the relevant series in the manner set forth in Section 106.

     With respect to any record date set pursuant to this Section, the party hereto which sets such
record dates may designate any day as the “Expiration Date” and from time to time may change the
Expiration Date to any earlier or later day; provided that no such change shall be effective unless
notice of the proposed new Expiration Date is given to the other party hereto in writing, and to
each Holder of Securities of the relevant series in the manner set forth in Section 106, on or
prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any
record date set pursuant to this Section, the party hereto which set such record date shall be
deemed to have initially designated the 180th day after such record date as the Expiration Date
with respect thereto, subject to its right to change the Expiration Date as provided in this
paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day
after the applicable record date.

     Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with
regard to any particular Security may do so with regard to all or any part of the principal

10

 

amount of such Security or by one or more duly appointed agents each of which may do so
pursuant to such appointment with regard to all or any part of such principal amount.

SECTION 105. Notices, Etc., to Trustee and Company.

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

     (1) the Trustee by any Holder or by the Company or any Subsidiary Guarantor shall be
sufficient for every purpose hereunder if made, given, furnished or filed in writing in the
English language to or with the Trustee at 1445 Ross Avenue, 2nd Floor, Dallas, Texas,
75202, Attention: Corporate Trust Department, Telecopy No. (214) 777-4086; or

     (2) the Company or any Subsidiary Guarantor by the Trustee or by any Holder shall be
sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in
writing in the English language and mailed, first-class postage prepaid, in the case of the
Company addressed to it at the address of its principal office specified in the first
paragraph of this instrument or at any other address previously furnished in writing to the
Trustee by the Company and, in the case of any Subsidiary Guarantor, to it at the address of
the Company’s principal office specified in the first paragraph of this instrument,
Attention: Chief Financial Officer, or at any other address previously furnished in writing
to the Trustee by such Subsidiary Guarantor.

SECTION 106. Notice to Holders; Waiver.

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

     In case by reason of the suspension of regular mail service or by reason of any other cause it
shall be impracticable to give such notice by mail, then such notification as shall be made with
the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

11

 

SECTION 107. Conflict with Trust Indenture Act.

     If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture
Act which is required under such Act to be a part of and govern this Indenture, the latter
provision shall control. If any provision of this Indenture modifies or excludes any provision of
the Trust Indenture Act which may be so modified or excluded, the latter provision shall be deemed
to apply to this Indenture as so modified or to be excluded, as the case may be.

SECTION 108. Effect of Headings and Table of Contents.

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

SECTION 109. Successors and Assigns.

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

SECTION 110. Separability Clause.

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

SECTION 111. Benefits of Indenture.

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

SECTION 112. Governing Law.

     This Indenture, the Securities and the Subsidiary Guarantees shall be governed by and
construed in accordance with the law of the State of New York.

SECTION 113. Legal Holidays.

     In any case where any Interest Payment Date, Redemption Date, purchase date or Stated Maturity
of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any
other provision of this Indenture or of the Securities (other than a provision of any Security
which specifically states that such provision shall apply in lieu of this Section)) payment of
interest or principal (and premium, if any) need not be made at such Place of Payment on such date,
but may be made on the next succeeding Business Day at such Place of Payment with the same force
and effect as if made on the Interest Payment Date, Redemption Date or purchase date, or at the
Stated Maturity.

Texas (herein called the “Company”, which term includes any successor Person under the Indenture
hereinafter referred to), for value received, hereby promises to pay to
                                        , or registered assigns, the principal sum of
                                                             Dollars on
                                                             [if the Security is to

or more Predecessor Securities) is registered at the close of business on the Regular Record Date

Securities) is registered at the close of business on a Special Record Date for the payment of such
Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of
Securities of this series not less than 10 days prior to such Special Record Date, or be paid at
any time in any other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities of this series may be listed, and upon such notice as may be

Securities of each series to be affected under the Indenture at any time by the

17

 

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

     As provided in and subject to the provisions of the Indenture, the Holder of this Security
shall not have the right to institute any proceeding with respect to the Indenture or for the
appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall
have previously given the Trustee written notice of a continuing Event of Default with respect to
the Securities of this series, the Holders of not less than 25% in principal amount of the
Securities of this series at the time Outstanding shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default as Trustee and offered the Trustee
reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in
principal amount of Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60 days after receipt of
such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted
by the Holder of this Security for the enforcement of any payment of principal hereof or any
premium or interest hereon on or after the respective due dates expressed herein.

     No reference herein to the Indenture and no provision of this Security or of the Indenture
shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay
the principal of and any premium and interest on this Security at the times, place and rate, and in
the coin or currency, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set forth, the
transfer of this Security is registrable in the Security Register, upon surrender of this Security
for registration of transfer at the office or agency of the Company in any place where the
principal of and any premium and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing,
and thereupon one or more new Securities of this series and of like tenor, of authorized
denominations and for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

     The Securities of this series are issuable only in registered form without coupons in
denominations of $ ___ and any integral multiple thereof. As provided in the Indenture and
subject to certain limitations therein set forth, Securities of this series are exchangeable for a
like aggregate principal amount of Securities of this series and of like tenor of a different
authorized denomination, as requested by the Holder surrendering the same.

18

 

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

Trustee and any agent of the Company or the Trustee may treat the Person in whose name this
Security is registered as the owner hereof for all purposes, whether or not this Security be
overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

     All terms used in this Security which are defined in the Indenture shall have the meanings
assigned to them in the Indenture.

SECTION 204. Form of Subsidiary Guarantee.

SUBSIDIARY GUARANTEE

     For value received, each of the Subsidiary Guarantors named (or deemed herein to be named)
below hereby jointly and severally fully and unconditionally guarantees to the Holder of the
Security upon which this Subsidiary Guarantee is endorsed, and to the Trustee on behalf of such
Holder, the due and punctual payment of the principal of (and premium, if any) and interest on such
Security when and as the same shall become due and payable, whether at the Stated Maturity, by
acceleration, call for redemption, offer to purchase or otherwise, according to the terms thereof
and of the Indenture referred to therein and to cover all the rights of the Trustee under Section
607. In case of the failure of the Company punctually to make any such payment, each of the
Subsidiary Guarantors hereby jointly and severally agrees to cause such payment to be made
punctually when and as the same shall become due and payable, whether at the Stated Maturity or by
acceleration, call for redemption, offer to purchase or otherwise, and as if such payment were made
by the Company.

     Each of the Subsidiary Guarantors hereby jointly and severally agrees that its obligations
hereunder shall be absolute and unconditional, irrespective of, and shall be unaffected by, the
validity, regularity or enforceability of such Security or the Indenture, the absence of any action
to enforce the same or any release, amendment, waiver or indulgence granted to the Company or any
other guarantor, or any consent to departure from any requirement of any other guarantee of all or
of any of the Securities of this series, or any other circumstances which might otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor; provided, however,
that, notwithstanding the foregoing, no such release, amendment, waiver or indulgence shall,
without the consent of such Subsidiary Guarantor, increase the principal amount of such Security,
or increase the interest rate thereon, or alter the Stated Maturity thereof. Each of the
Subsidiary Guarantors hereby waives the benefits of diligence, presentment, demand of payment, any
requirement that the Trustee or any of the Holders protect, secure, perfect or insure any security
interest in or other lien on any property subject thereto or exhaust any right or take any action
against the Company or any other Person or any collateral, filing of claims with a court in the
event of insolvency or bankruptcy of the Company, any right to require a proceeding first against
the Company, protest or notice with respect to such Security or the indebtedness evidenced thereby
and all demands whatsoever, and covenants that this Subsidiary Guarantee

19

 

will not be discharged except by complete performance of the obligations contained in such
Security and in this Subsidiary Guarantee. Each Subsidiary Guarantor agrees that if, after the
occurrence and during the continuance of an Event of Default with respect to Securities of this
series, the Trustee or any of the Holders are prevented by applicable law from exercising their
respective rights to accelerate the maturity of the Securities of this series, to collect interest
on the Securities of this series, or to enforce or exercise any other right or remedy with respect
to the Securities of this series, such Subsidiary Guarantor agrees to pay to the Trustee for the
account of the Holders, upon demand therefor, the amount that would otherwise have been due and
payable had such rights and remedies been permitted to be exercised by the Trustee or any of the
Holders.

     The indebtedness of each Subsidiary Guarantor evidenced by this Subsidiary Guarantee is, to
the extent provided in the Indenture, subordinate in right of payment to the prior payment in full
of all Senior Debt of such Subsidiary Guarantor, and the Subsidiary Guarantee of each Subsidiary
Guarantor is issued subject to the provisions of the Indenture with respect thereto.

     No reference herein to the Indenture and no provision of this Subsidiary Guarantee or of the
Indenture shall alter or impair the Subsidiary Guarantee of any Subsidiary Guarantor, which is
absolute and unconditional, of the due and punctual payment of the principal (and premium, if any)
and interest on the Security upon which this Subsidiary Guarantee is endorsed.

     Each Subsidiary Guarantor shall be subrogated to all rights of the Holder of this Security
against the Company in respect of any amounts paid by such Subsidiary Guarantor on account of this
Security pursuant to the provisions of its Subsidiary Guarantee or the Indenture; provided,
however, that such Subsidiary Guarantor shall not be entitled to enforce or to receive any payments
arising out of, or based upon, such right of subrogation until the principal of (and premium, if
any) and interest on this Security and all other Securities of this series issued under the
Indenture shall have been paid in full.

     This Subsidiary Guarantee shall remain in full force and effect and continue to be effective
should any petition be filed by or against the Company for liquidation or reorganization, should
the Company become insolvent or make an assignment for the benefit of creditors or should a
receiver or trustee be appointed for all or any part of the Company’s assets, and shall, to the
fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if
at any time payment and performance of the Securities of this series is, pursuant to applicable
law, rescinded or reduced in amount, or must otherwise be restored or returned by any Holder of the
Securities of this series, whether as a “voidable preference”, “fraudulent transfer”, or otherwise,
all as though such payment or performance had not been made. In the event that any payment, or any
part thereof, is rescinded, reduced, restored or returned, the Securities of this series shall, to
the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and
not so rescinded, reduced, restored or returned.

     The Subsidiary Guarantors or any particular Subsidiary Guarantor shall be released from this
Subsidiary Guarantee upon the terms and subject to certain conditions provided in the Indenture.

20

 

     By delivery to the Trustee of a supplement to the Indenture referred to in the Security upon
which this Subsidiary Guarantee is endorsed in accordance with the terms of the Indenture, each
Person that becomes a Subsidiary Guarantor after the date of first issuance of the Securities of
this series will be deemed to have executed and delivered this Subsidiary Guarantee for the benefit
of the Holder of the Security upon which this Subsidiary Guarantee is endorsed with the same effect
as if such Subsidiary Guarantor was named below and has executed and delivered this Subsidiary
Guarantee.

     All terms used in this Subsidiary Guarantee which are defined in the Indenture shall have the
meanings assigned to them in such Indenture.

     This Subsidiary Guarantee shall not be valid or obligatory for any purpose until the
certificate of authentication on the Security upon which this Subsidiary Guarantee is endorsed
shall have been executed by the Trustee under the Indenture by manual signature.

     Reference is made to the Indenture for further provisions with respect to this Subsidiary
Guarantee.

     This Subsidiary Guarantee shall be governed by and construed in accordance with the laws of
the State of New York.

     IN WITNESS WHEREOF, each of the Subsidiary Guarantors has caused this Subsidiary Guarantee to
be duly executed.

may be registered, in the name or names of Persons other than the Depositary for such Global
Security or a nominee thereof;

     (19) any addition to or change in the Events of Default which applies to any Securities
of the series and any change in the right of the Trustee or the requisite Holders of such
Securities to declare the principal amount thereof due and payable pursuant to Section 502;

     (20) any addition to or change in the covenants set forth in Article Ten which applies
to Securities of the series;

     (21) whether the Securities of the series will be convertible into Common Stock (or
cash in lieu thereof) and, if so, the terms and conditions upon which such conversion will
be effected; and

     (22) any other terms of the series (which terms shall not be inconsistent with the
provisions of this Indenture, except as permitted by Section 901(5)).

     All Securities of any one series shall be substantially identical except as to denomination
and except as may otherwise be provided in or pursuant to the Board Resolution referred to

25

 

above and (subject to Section 303) set forth, or determined in the manner provided, in the
Officers’ Certificate referred to above or in any such indenture supplemental hereto.

     If any of the terms of the series are established by action taken pursuant to a Board
Resolution, a copy of an appropriate record of such action shall be certified by the Secretary or
an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of
the Officers’ Certificate setting forth the terms of the series.

     The Securities shall be subordinated in right of payment to Senior Debt of the Company as
provided in Article Twelve. Each Subsidiary Guarantee shall be subordinated in right of payment to
Senior Debt of the applicable Subsidiary Guarantor as provided in Article Fourteen.

SECTION 302. Denominations.

     The Securities of each series shall be issuable only in registered form without coupons and
only in such denominations as shall be specified as contemplated by Section 301. In the absence of
any such specified denomination with respect to the Securities of any series, the Securities of
such series shall be issuable in denominations of $1,000 and any integral multiple thereof.

SECTION 303. Execution, Authentication, Delivery and Dating.

     The Securities shall be executed on behalf of the Company by its Chairman of the Board of
Directors, its Vice Chairman of the Board of Directors, its President or one of its Vice
Presidents. If its corporate seal is reproduced thereon, then it shall be attested by its
Secretary or one of its Assistant Secretaries. The signature of any of these officers on the
Securities may be manual or facsimile.

     Securities bearing the manual or facsimile signatures of individuals who were at any time the
proper officers of the Company shall bind the Company, notwithstanding that such individuals or any
of them have ceased to hold such offices prior to the authentication and delivery of such
Securities or did not hold such offices at the date of such Securities.

     At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Securities of any series executed by the Company and, if applicable, having
endorsed thereon the Subsidiary Guarantees executed as provided in Section 1303 by the Subsidiary
Guarantors to the Trustee for authentication, together with a Company Order for the authentication
and delivery of such Securities, and the Trustee in accordance with the Company Order shall
authenticate and deliver such Securities. If the form or terms of the Securities of the series
have been established by or pursuant to one or more Board Resolutions as permitted by Sections 201
and 301, in authenticating such Securities, and accepting the additional responsibilities under
this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and
(subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating,

     (1) if the form of such Securities has been established by or pursuant to Board
Resolution as permitted by Section 201, that such form has been established in conformity
with the provisions of this Indenture;

26

 

     (2) if the terms of such Securities have been established by or pursuant to Board
Resolution as permitted by Section 301, that such terms have been established in conformity
with the provisions of this Indenture; and

     (3) that such Securities, when authenticated and delivered by the Trustee and issued by
the Company in the manner and subject to any conditions specified in such Opinion of
Counsel, will constitute valid and legally binding obligations of the Company, and, if
applicable, the Subsidiary Guarantees endorsed thereon will constitute valid and legally
binding obligations of the Subsidiary Guarantors, enforceable in accordance with their
terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium
and similar laws of general applicability relating to or affecting creditors’ rights and to
general equity principles.

If such form or terms have been so established, the Trustee shall not be required to authenticate
such Securities if the issue of such Securities pursuant to this Indenture will affect the
Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in
a manner which is not reasonably acceptable to the Trustee.

     Notwithstanding the provisions of Section 301 and of the preceding paragraph, if all
Securities of a series are not to be originally issued at one time, it shall not be necessary to
deliver the Officers’ Certificate otherwise required pursuant to Section 301 or the Company Order
and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered at or prior to the
authentication upon original issuance of the first Security of such series to be issued.

     Each Security shall be dated the date of its authentication.

     No Security or Subsidiary Guarantee shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Security a certificate of
authentication substantially in the form provided for herein executed by the Trustee by manual
signature, and such certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding
the foregoing, if any Security shall have been authenticated and delivered hereunder but never
issued and sold by the Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided in Section 309, for all purposes of this Indenture such Security shall be
deemed never to have been authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

SECTION 304. Temporary Securities.

     Pending the preparation of definitive Securities of any series, the Company may execute, and
upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are
printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Securities and, if applicable, having
endorsed thereon the Subsidiary Guarantees in lieu of which they are issued and with such
appropriate insertions, omissions, substitutions and other variations as the officers executing

27

 

such Securities and, if applicable, Subsidiary Guarantees may determine, as evidenced by their
execution of such Securities and Subsidiary Guarantees.

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

SECTION 305. Registration, Registration of Transfer and Exchange.

     The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register
(the register maintained in such office and in any other office or agency of the Company in a Place
of Payment being herein sometimes collectively referred to as the “Security Register”) in which,
subject to such reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is hereby appointed
“Security Registrar” for the purpose of registering Securities and transfers of Securities as
herein provided.

     Upon surrender for registration of transfer of any Security of a series at the office or
agency of the Company in a Place of Payment for that series, the Company shall execute, if
applicable the Subsidiary Guarantors shall execute the Subsidiary Guarantees endorsed thereon and
the Trustee shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount.

     At the option of the Holder, Securities of any series may be exchanged for other Securities of
the same series, of any authorized denominations and of like tenor and aggregate principal amount,
upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities
are so surrendered for exchange, the Company shall execute, if applicable the Subsidiary Guarantors
shall execute the Subsidiary Guarantees endorsed thereon and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to receive.

     All Securities and, if applicable, the Subsidiary Guarantees endorsed thereon issued upon any
registration of transfer or exchange of Securities shall be the valid obligations of the Company
and, if applicable, the respective Subsidiary Guarantors, evidencing the same debt, and entitled to
the same benefits under this Indenture, as the Securities and Subsidiaries Guarantees surrendered
upon such registration of transfer or exchange.

28

 

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

     No service charge shall be made for any registration of transfer or exchange of Securities,
but the Company may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer or exchange of
Securities, other than exchanges pursuant to Section 304, 906, 1107 or otherwise not involving any
transfer.

     If the Securities of any series (or of any series and specified tenor) are to be redeemed in
part, the Company shall not be required (A) to issue, register the transfer of or exchange any
Securities of that series (or of that series and specified tenor, as the case may be) during a
period beginning at the opening of business 15 days before the day of the mailing of a notice of
redemption of any such Securities selected for redemption under Section 1103 and ending at the
close of business on the day of such mailing, or (B) to register the transfer of or exchange any
Security so selected for redemption in whole or in part, except the unredeemed portion of any
Security being redeemed in part.

     The provisions of clauses (1), (2), (3) and (4) below shall apply only to Global Securities:

     (1) Each Global Security authenticated under this Indenture shall be registered in the
name of the Depositary designated for such Global Security or a nominee thereof and
delivered to such Depositary or a nominee thereof or custodian therefor, and each such
Global Security shall constitute a single Security for all purposes of this Indenture.

     (2) Notwithstanding any other provision in this Indenture, no Global Security may be
exchanged in whole or in part for Securities registered, and no transfer of a Global
Security in whole or in part may be registered, in the name of any Person other than the
Depositary for such Global Security or a nominee thereof unless (A) such Depositary (i) has
notified the Company that it is unwilling or unable to continue as Depositary for such
Global Security or (ii) has ceased to be a clearing agency registered under the Exchange
Act, and in either case the Company fails to appoint a successor Depositary within 90 days,
(B) there shall have occurred and be continuing an Event of Default with respect to such
Global Security and the Depositary shall have notified the Trustee of its decision to
exchange such Global Security for Securities in certificated form or (C) there shall exist
such circumstances, if any, in addition to or in lieu of the foregoing as have been
specified for this purpose as contemplated by Section 301.

     (3) Subject to clause (2) above, any exchange of a Global Security for other Securities
may be made in whole or in part, and all Securities issued in exchange for a Global Security
or any portion thereof shall be registered in such names as the Depositary for such Global
Security shall direct.

     (4) Every Security authenticated and delivered upon registration of transfer of, or in
exchange for or in lieu of, a Global Security or any portion thereof, whether

29

 

pursuant to this Section, Section 304, 306, 906 or 1107 or otherwise, shall be
authenticated and delivered in the form of, and shall be, a Global Security, unless such
Security is registered in the name of a Person other than the Depositary for such Global
Security or a nominee thereof.

SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities.

     If any mutilated Security is surrendered to the Trustee, the Company shall execute, if
applicable the Subsidiary Guarantors shall execute the Subsidiary Guarantees endorsed thereon and
the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series
and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

     If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction
of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be
required by them to save each of them and any agent of either of them harmless from any loss that
any of them may suffer if a Security is replaced, then, in the absence of notice to the Company or
the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall
execute, if applicable the Subsidiary Guarantors shall execute the Subsidiary Guarantees endorsed
thereon and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or
stolen Security, a new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding.

     In case any such mutilated, destroyed, lost or stolen Security has become or is about to
become due and payable or is to be converted, the Company in its discretion may, instead of issuing
a new Security, pay or authorize the conversion of such Security (without surrender thereof save in
the case of a mutilated Security).

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

     Every new Security of any series issued pursuant to this Section in lieu of any destroyed,
lost or stolen Security, and, if applicable, the Subsidiary Guarantees endorsed thereon, shall
constitute an original additional contractual obligation of the Company and, if applicable, the
respective Subsidiary Guarantors, whether or not the destroyed, lost or stolen Security shall be at
any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally
and proportionately with any and all other Securities of that series duly issued hereunder.

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

SECTION 307. Payment of Interest; Interest Rights Preserved.

     Except as otherwise provided as contemplated by Section 301 with respect to any series of
Securities, interest on any Security which is payable, and is punctually paid or duly provided

30

 

for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or
one or more Predecessor Securities) is registered at the close of business on the Regular Record
Date for such interest.

     Any interest on any Security of any series which is payable, but is not punctually paid or
duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall
forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having
been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (1) or (2) below:

     (1) The Company may elect to make payment of any Defaulted Interest to the Persons in
whose names the Securities of such series (or their respective Predecessor Securities) are
registered at the close of business on a Special Record Date for the payment of such
Defaulted Interest, which shall be fixed in the following manner. The Company shall notify
the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each
Security of such series and the date of the proposed payment, and at the same time the
Company shall deposit with the Trustee an amount of money equal to the aggregate amount
proposed to be paid in respect of such Defaulted Interest or shall make arrangements
satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such
money when deposited to be held in trust for the benefit of the Persons entitled to such
Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a Special
Record Date for the payment of such Defaulted Interest which shall be not more than 15 days
and not less than 10 days prior to the date of the proposed payment and not less than 10
days after the receipt by the Trustee of the notice of the proposed payment. The Trustee
shall promptly notify the Company of such Special Record Date and, in the name and at the
expense of the Company, shall cause notice of the proposed payment of such Defaulted
Interest and the Special Record Date therefor to be given to each Holder of Securities of
such series in the manner set forth in Section 106, not less than 10 days prior to such
Special Record Date. Notice of the proposed payment of such Defaulted Interest and the
Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to
the Persons in whose names the Securities of such series (or their respective Predecessor
Securities) are registered at the close of business on such Special Record Date and shall no
longer be payable pursuant to the following clause (2).

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

     Subject to the foregoing provisions of this Section, each Security delivered under this
Indenture upon registration of transfer of or in exchange for or in lieu of any other Security
shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such
other Security.

31

 

SECTION 308. Persons Deemed Owners.

     Prior to due presentment of a Security for registration of transfer, the Company, the
Subsidiary Guarantors, the Trustee and any agent of the Company, the Subsidiary Guarantors, or the
Trustee may treat the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and any premium and (subject to
Section 307) any interest on such Security and for all other purposes whatsoever, whether or not
such Security be overdue, and neither the Company, any Subsidiary Guarantor, the Trustee nor any
agent of the Company, any Subsidiary Guarantor, or the Trustee shall be affected by notice to the
contrary.

SECTION 309. Cancellation.

     All Securities surrendered for payment, redemption, purchase, registration of transfer or
exchange or for credit against any sinking fund payment shall, if surrendered to any Person other
than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company
may at any time deliver to the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver
to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold, and all Securities so
delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities cancelled as provided in this Section, except as expressly
permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of as
directed by a Company Order.

SECTION 310. Computation of Interest.

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

or (iii) above, has irrevocably deposited or caused to be deposited with the Trustee
as trust funds in trust for the purpose money in an amount sufficient, without
consideration of any reinvestment of interest, to pay and discharge the entire
indebtedness on such Securities not theretofore delivered to the Trustee for
cancellation, for principal and any premium and interest to the date of such deposit
(in the case of Securities which have become due and payable) or to the Stated
Maturity or Redemption Date, as the case may be;

     (2) the Company or a Subsidiary Guarantor has paid or caused to be paid all other sums

Company to the Trustee under Section 607, any surviving rights of conversion, the obligations of
the Trustee to any Authenticating Agent under Section 614 and, if money shall have been deposited
with the Trustee pursuant to subclause (B) of clause (1) of this Section, the obligations of the
Trustee under Section 402 and the last paragraph of Section 1003 shall survive.

SECTION 402. Application of Trust Money.

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

33

 

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

ARTICLE FIVE

held by a final non-appealable order or judgment of a court of competent jurisdiction to be
unenforceable or invalid or ceases for any reason to be in full force and effect (other than
in accordance with the terms of this Indenture) or such Subsidiary Guarantor or any Person

Guarantor’s obligations under its Subsidiary Guarantee (other than by reason of a release of
such Subsidiary Guarantor from its Subsidiary Guarantee in accordance with the terms of this
Indenture); or

     (9) any other Event of Default provided with respect to Securities of that series.

SECTION 502. Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default (other than an Event of Default with respect to the Company specified
in Section 501(6) or 501(7)) with respect to Securities of any series at the time

35

 

Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of
not less than 25% in principal amount of the Outstanding Securities of that series may declare the
principal amount of all the Securities of that series (or, if any Securities of that series are
Original Issue Discount Securities, such portion of the principal amount of such Securities as may
be specified by the terms thereof) to be due and payable immediately, by a notice in writing to the
Company (and to the Trustee if given by Holders), and upon any such declaration such principal
amount (or specified amount) shall become immediately due and payable, together with any accrued
and unpaid interest thereon. If an Event of Default with respect to the Company specified in
Section 501(6) or 501(7) with respect to Securities of any series at the time Outstanding occurs,
the principal amount of all the Securities of that series (or, if any Securities of that series are
Original Issue Discount Securities, such portion of the principal amount of such Securities as may
be specified by the terms thereof) shall automatically, and without any declaration or other action
on the part of the Trustee or any Holder, become immediately due and payable, together with any
accrued and unpaid interest thereon.

     At any time after such a declaration of acceleration with respect to Securities of any series
has been made and before a judgment or decree for payment of the money due has been obtained by the
Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of
the Outstanding Securities of that series, by written notice to the Company and the Trustee, may
rescind and annul such declaration and its consequences if

     (1) the Company or, if applicable, any Subsidiary Guarantor has paid or deposited with
the Trustee a sum sufficient to pay

     (A) all overdue interest on all Securities of that series,

     (B) the principal of (and premium, if any, on) any Securities of that
series which have become due otherwise than by such declaration of
acceleration and any interest thereon at the rate or rates prescribed
therefor in such Securities,

     (C) to the extent that payment of such interest is lawful, interest
upon overdue interest at the rate or rates prescribed therefor in such
Securities, and

     (D) all sums paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel;

     and

     (2) all Events of Default with respect to Securities of that series, other than the
non-payment of the principal of Securities of that series which has become due solely by
such declaration of acceleration, have been cured or waived as provided in Section 513.

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

SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee.

     The Company covenants that if

     (1) default is made in the payment of any interest on any Security when such interest
becomes due and payable and such default continues for a period of 30 days, or

     (2) default is made in the payment of the principal of (or premium, if any, on) any
Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such
Securities, the whole amount then due and payable on such Securities for principal and any premium
and interest and, to the extent that payment of such interest shall be legally enforceable,
interest on any overdue principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be
sufficient to cover the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

     If an Event of Default with respect to Securities of any series occurs and is continuing, the
Trustee may in its discretion proceed to protect and enforce its rights and the rights of the
Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall
deem most effectual to protect and enforce any such rights, whether for the specific enforcement of
any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein,
or to enforce any other proper remedy.

SECTION 504. Trustee May File Proofs of Claim.

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

     No provision of this Indenture shall be deemed to authorize the Trustee to authorize or
consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or any Subsidiary Guarantee or the rights of any
Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any
such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the
election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other
similar committee.

37

 

SECTION 505. Trustee May Enforce Claims Without Possession of Securities.

     All rights of action and claims under this Indenture or the Securities or any Subsidiary
Guarantee may be prosecuted and enforced by the Trustee without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and any such proceeding
instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable
benefit of the Holders of the Securities in respect of which such judgment has been recovered.

SECTION 506. Application of Money Collected.

     Any money collected by the Trustee pursuant to this Article shall be applied in the following
order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on
account of principal or any premium or interest, upon presentation of the Securities and the
notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

     FIRST: To the payment of all amounts due the Trustee under Section 607;

     SECOND: Subject to Article Twelve and Article Fourteen, to the payment of the
amounts then due and unpaid for principal of and any premium and interest on the
Securities in respect of which or for the benefit of which such money has been
collected, ratably, without preference or priority of any kind, according to the
amounts due and payable on such Securities for principal and any premium and
interest, respectively; and

     THIRD: The balance, if any, to the Company or to such other Person as a court
of competent jurisdiction shall direct.

SECTION 507. Limitation on Suits.

     No Holder of any Security of any series shall have any right to institute any proceeding,
judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or
trustee, or for any other remedy hereunder, unless

     (1) such Holder has previously given written notice to the Trustee of a continuing
Event of Default with respect to the Securities of that series;

     (2) the Holders of not less than 25% in principal amount of the Outstanding Securities
of that series shall have made written request to the Trustee to institute proceedings in
respect of such Event of Default in its own name as Trustee hereunder;

     (3) such Holder or Holders have offered to the Trustee reasonable security or indemnity
against the costs, expenses and liabilities to be incurred in compliance with such request;

38

 

     (4) the Trustee for 60 days after its receipt of such notice, request and offer of
security or indemnity has failed to institute any such proceeding; and

     (5) no direction inconsistent with such written request has been given to the Trustee
during such 60-day period by the Holders of a majority in principal amount of the
Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall have any right in any
manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb
or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or
preference over any other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such Holders.

SECTION 508. Unconditional Right of Holders to Receive Principal, Premium and Interest.

     Notwithstanding any other provision in this Indenture, the Holder of any Security shall have
the right, which is absolute and unconditional, to receive payment of the principal of and any
premium and (subject to Section 307) interest on such Security on the respective Stated Maturities
expressed in such Security (or, in the case of redemption or offer by the Company to purchase the
Securities pursuant to the terms of this Indenture, on the Redemption Date or purchase date, as
applicable) and, if applicable, to convert such Security in accordance with its terms, and to
institute suit for the enforcement of any such right, and such rights shall not be impaired without
the consent of such Holder.

SECTION 509. Restoration of Rights and Remedies.

     If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy
under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has
been determined adversely to the Trustee or to such Holder, then and in every such case, subject to
any determination in such proceeding, the Company, the Subsidiary Guarantors, the Trustee and the
Holders shall be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.

SECTION 510. Rights and Remedies Cumulative.

     Except as otherwise provided with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy
herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of
any other right or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

39

 

SECTION 511. Delay or Omission Not Waiver.

     No delay or omission of the Trustee or of any Holder of any Securities to exercise any right
or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a
waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by
this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

SECTION 512. Control by Holders.

     The Holders of a majority in principal amount of the Outstanding Securities of any series
shall have the right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with
respect to the Securities of such series, provided that

     (1) such direction shall not be in conflict with any rule of law or with this
Indenture, and

     (2) the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction.

SECTION 513. Waiver of Past Defaults.

     The Holders of not less than a majority in principal amount of the Outstanding Securities of
any series may on behalf of the Holders of all the Securities of such series waive any past default
hereunder with respect to such series and its consequences, except a default

     (1) in the payment of the principal of or any premium or interest on any Security of
such series (including any Security which is required to have been purchased by the Company
pursuant to an offer to purchase by the Company made pursuant to the terms of this
Indenture), or

     (2) in respect of a covenant or provision hereof which under Article Nine cannot be
modified or amended without the consent of the Holder of each Outstanding Security of such
series.

     Upon any such waiver, such default shall cease to exist, and any Event of Default arising
therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such
waiver shall extend to any subsequent or other default or impair any right consequent thereon.

SECTION 514. Undertaking for Costs.

     In any suit for the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require
any party litigant in such suit to file an undertaking to pay the costs of such suit, and may
assess costs against any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided, however, that neither this Section nor the Trust Indenture Act shall be

40

 

deemed to authorize any court to require such an undertaking or to make such an assessment in
any suit instituted by the Company or any Subsidiary Guarantor.

SECTION 515. Waiver of Usury, Stay or Extension Laws.

     Each of the Company and the Subsidiary Guarantors covenants (to the extent that it may
lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now
or at any time hereafter in force, which may affect the covenants or the performance of this
Indenture; and each of the Company and the Subsidiary Guarantors (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that
it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but
will suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE SIX

THE TRUSTEE

SECTION 601. Certain Duties and Responsibilities.

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

SECTION 602. Notice of Defaults.

     If a default occurs hereunder with respect to Securities of any series, the Trustee shall give
the Holders of Securities of such series notice of such default as and to the extent provided by
the Trust Indenture Act; provided, however, that in the case of any default of the character
specified in Section 501(5) with respect to Securities of such series, no such notice to Holders
shall be given until at least 30 days after the occurrence thereof. For the purpose of this
Section, the term “default” means any event which is, or after notice or lapse of time or both
would become, an Event of Default with respect to Securities of such series.

SECTION 603. Certain Rights of Trustee.

     Subject to the provisions of Section 601:

     (1) the Trustee may rely and shall be protected in acting or refraining from acting
upon any resolution, certificate, statement, instrument, opinion, report, notice,

41

 

request, direction, consent, order, bond, debenture, note, other evidence of
indebtedness or other paper or document believed by it to be genuine and to have been signed
or presented by the proper party or parties;

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

     (3) whenever in the administration of this Indenture the Trustee shall deem it
desirable that a matter be proved or established prior to taking, suffering or omitting any
action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may,
in the absence of bad faith on its part, rely upon an Officers’ Certificate;

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

     (5) the Trustee shall be under no obligation to exercise any of the rights or powers
vested in it by this Indenture at the request or direction of any of the Holders pursuant to
this Indenture, unless such Holders shall have offered to the Trustee reasonable security or
indemnity against the costs, expenses and liabilities which might be incurred by it in
compliance with such request or direction;

     (6) the Trustee shall not be bound to make any investigation into the facts or matters
stated in any resolution, certificate, statement, instrument, opinion, report, notice,
request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or
other paper or document, but the Trustee, in its discretion, may make such further inquiry
or investigation into such facts or matters as it may see fit, and, if the Trustee shall
determine to make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Company, personally or by agent or attorney; and

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

SECTION 604. Not Responsible for Recitals or Issuance of Securities.

     The recitals contained herein and in the Securities and the Subsidiary Guarantees, except the
Trustee’s certificates of authentication, shall be taken as the statements of the Company or the
Subsidiary Guarantors, as the case may be, and neither the Trustee nor any Authenticating Agent
assumes any responsibility for their correctness. The Trustee makes no representations as to the
validity or sufficiency of this Indenture or of the Securities or the Subsidiary Guarantees
endorsed thereon. Neither the Trustee nor any Authenticating Agent shall be accountable for the
use or application by the Company of Securities or the proceeds thereof.

42

 

SECTION 605. May Hold Securities.

     The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other
agent of the Company or any Subsidiary Guarantor, in its individual or any other capacity, may
become the owner or pledgee of Securities and, subject to Sections 608 and 613, may otherwise deal
with the Company and any Subsidiary Guarantor with the same rights it would have if it were not
Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent.

SECTION 606. Money Held in Trust.

     Money held by the Trustee in trust hereunder need not be segregated from other funds except to
the extent required by law. The Trustee shall be under no liability for interest on any money
received by it hereunder except as otherwise agreed with the Company or any Subsidiary Guarantor,
as the case may be.

SECTION 607. Compensation and Reimbursement.

     The Company and each Subsidiary Guarantor jointly and severally agree

     (1) to pay to the Trustee from time to time reasonable compensation for all services
rendered by it hereunder (which compensation shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust);

     (2) except as otherwise expressly provided herein, to reimburse the Trustee upon its
request for all reasonable expenses, disbursements and advances incurred or made by the
Trustee in accordance with any provision of this Indenture (including the reasonable
compensation and the expenses and disbursements of its agents and counsel), except any such
expense, disbursement or advance as may be attributable to its negligence or bad faith; and

     (3) to indemnify the Trustee for, and to hold it harmless against, any loss, liability
or expense incurred without negligence or bad faith on its part, arising out of or in
connection with the acceptance or administration of the trust or trusts hereunder, including
the costs and expenses of defending itself against any claim or liability in connection with
the exercise or performance of any of its powers or duties hereunder.

SECTION 608. Conflicting Interests.

     If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust
Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the
manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture.
To the extent permitted by such Act, the Trustee shall not be deemed to have a conflicting interest
by virtue of being a trustee under this Indenture with respect to Securities of more than one
series.

43

 

SECTION 609. Corporate Trustee Required; Eligibility.

     There shall at all times be one (and only one) Trustee hereunder with respect to the
Securities of each series, which may be Trustee hereunder for Securities of one or more other
series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act
as such, and has a combined capital and surplus of at least $50,000,000. If any such Person
publishes reports of condition at least annually, pursuant to law or to the requirements of its
supervising or examining authority, then for the purposes of this Section and to the extent
permitted by the Trust Indenture Act, the combined capital and surplus of such Person shall be
deemed to be its combined capital and surplus as set forth in its most recent report of condition
so published. If at any time the Trustee with respect to the Securities of any series shall cease
to be eligible in accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article.

SECTION 610. Resignation and Removal; Appointment of Successor.

     No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to
this Article shall become effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 611.

     The Trustee may resign at any time with respect to the Securities of one or more series by
giving written notice thereof to the Company. If the instrument of acceptance by a successor
Trustee required by Section 611 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the Securities of such
series.

     The Trustee may be removed at any time with respect to the Securities of any series by Act of
the Holders of a majority in principal amount of the Outstanding Securities of such series,
delivered to the Trustee and to the Company.

     If at any time:

     (1) the Trustee shall fail to comply with Section 608 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

     (2) the Trustee shall cease to be eligible under Section 609 and shall fail to resign
after written request therefor by the Company or by any such Holder, or

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

then, in any such case, (A) the Company by a Board Resolution may remove the Trustee with respect
to all Securities, or (B) subject to Section 514, any Holder who has been a bona fide Holder of a
Security for at least six months may, on behalf of himself and all others similarly

44

 

situated, petition any court of competent jurisdiction for the removal of the Trustee with respect
to all Securities and the appointment of a successor Trustee or Trustees.

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

     The Company shall give notice of each resignation and each removal of the Trustee with respect
to the Securities of any series and each appointment of a successor Trustee with respect to the
Securities of any series to all Holders of Securities of such series in the manner provided in
Section 106. Each notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office.

SECTION 611. Acceptance of Appointment by Successor.

     In case of the appointment hereunder of a successor Trustee with respect to all Securities,
every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company,
the Subsidiary Guarantors and to the retiring Trustee an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or
the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of
the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all
property and money held by such retiring Trustee hereunder.

     In case of the appointment hereunder of a successor Trustee with respect to the Securities of
one or more (but not all) series, the Company, the Subsidiary Guarantors, the retiring Trustee and
each successor Trustee with respect to the Securities of one or more series shall execute and
deliver an indenture supplemental hereto wherein each successor Trustee shall accept such
appointment and which (1) shall contain such provisions as shall be necessary or desirable to

45

 

transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts
and duties of the retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with
respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable
to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to
the Securities of that or those series as to which the retiring Trustee is not retiring shall
continue to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions
of this Indenture as shall be necessary to provide for or facilitate the administration of the
trusts hereunder by more than one Trustee, it being understood that nothing herein or in such
supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each
such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or
trusts hereunder administered by any other such Trustee; and upon the execution and delivery of
such supplemental indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee, without any further act,
deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which the appointment of
such successor Trustee relates; but, on request of the Company or any successor Trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

     Upon request of any such successor Trustee, the Company and the Subsidiary Guarantors shall
execute any and all instruments for more fully and certainly vesting in and confirming to such
successor Trustee all such rights, powers and trusts referred to in the first or second preceding
paragraph, as the case may be.

     No successor Trustee shall accept its appointment unless at the time of such acceptance such
successor Trustee shall be qualified and eligible under this Article.

SECTION 612. Merger, Conversion, Consolidation or Succession to Business.

     Any Person into which the Trustee may be merged or converted or with which it may be
consolidated, or any Person resulting from any merger, conversion or consolidation to which the
Trustee shall be a party, or any Person succeeding to all or substantially all the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder, provided such Person
shall be otherwise qualified and eligible under this Article, without the execution or filing of
any paper or any further act on the part of any of the parties hereto. As soon as practicable, the
successor Trustee shall mail a notice of its succession to the Company and the Holders of the
Securities then Outstanding. In case any Securities shall have been authenticated, but not
delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to
such authenticating Trustee may adopt such authentication and deliver the Securities so
authenticated with the same effect as if such successor Trustee had itself authenticated such
Securities.

46

 

SECTION 613. Preferential Collection of Claims Against Company and Subsidiary Guarantors.

     If and when the Trustee shall be or become a creditor of the Company, any Subsidiary Guarantor
or any other obligor upon the Securities, the Trustee shall be subject to the provisions of the
Trust Indenture Act regarding the collection of claims against the Company, such Subsidiary
Guarantor or any such other obligor.

SECTION 614. Appointment of Authenticating Agent.

     The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series
of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities
of such series issued upon original issue and upon exchange, registration of transfer, conversion
or partial redemption thereof or pursuant to Section 306, and Securities so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee’s certificate of
authentication, such reference shall be deemed to include authentication and delivery on behalf of
the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a Person organized and doing business under the laws of the
United States of America, any State thereof or the District of Columbia, authorized under such laws
to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000
and subject to supervision or examination by Federal or State authority. If such Authenticating
Agent publishes reports of condition at least annually, pursuant to law or to the requirements of
said supervising or examining authority, then for the purposes of this Section, the combined
capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section,
such Authenticating Agent shall resign immediately in the manner and with the effect specified in
this Section.

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

     An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee
and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by
giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such
a notice of resignation or upon such a termination, or in case at any time such Authenticating
Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may
appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give
notice of such appointment in the manner provided in

47

 

Section 106 to all Holders of Securities of the series with respect to which such
Authenticating Agent will serve. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent. No successor
Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

     The Trustee agrees to pay to each Authenticating Agent from time to time reasonable
compensation for its services under this Section, and the Trustee shall be entitled to be
reimbursed for such payments, subject to the provisions of Section 607.

     If an appointment with respect to one or more series is made pursuant to this Section, the
Securities of such series may have endorsed thereon, in addition to the Trustee’s certificate of
authentication, an alternative certificate of authentication in the following form:

     This is one of the Securities of the series designated therein referred to in the
within-mentioned Indenture.

Securities of each series:

     (1) not more than 10 days after each record date with respect to the payment of
interest, if any, a list, in such form as the Trustee may reasonably require, of the names

excluding from any such list names and addresses received by the Trustee in its capacity as
Security Registrar.

SECTION 702. Preservation of Information; Communications to Holders.

     The Trustee shall preserve, in as current a form as is reasonably practicable, the names and

manner provided pursuant to such Act; provided that any such information, documents or reports
required to be filed with the Commission pursuant to Section 13 or 15(d) of the Exchange Act shall
be filed with the Trustee within 15 days after the same is so required to be filed with the
Commission.

SECTION 902. Supplemental Indentures With Consent of Holders.

     With the consent of the Holders of not less than a majority in principal amount of the

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

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

SECTION 903. Execution of Supplemental Indentures.

     In executing, or accepting the additional trusts created by, any supplemental indenture

under this Indenture or otherwise.

of the Trustee and the Company, to any such supplemental indenture may be prepared and executed by
the Company, if applicable the Subsidiary Guarantees may be endorsed thereon and such new
Securities may be authenticated and delivered by the Trustee in exchange for Outstanding Securities
of such series.

ARTICLE TEN

COVENANTS

SECTION 1001. Payment of Principal, Premium and Interest.

     The Company covenants and agrees for the benefit of each series of Securities that it will
duly and punctually pay the principal of and any premium and interest on the Securities of that
series in accordance with the terms of the Securities and this Indenture. Principal, premium, if
any, and interest shall be considered paid on the date due if the Paying Agent, if other than the
Company or a Subsidiary thereof, holds as of 11:00 A.M., New York City time, on the due date money
deposited by the Company in immediately available funds and designated for and sufficient to pay
all principal, premium, if any, and interest then due.

SECTION 1002. Maintenance of Office or Agency.

     The Company will maintain in each Place of Payment for any series of Securities an office or
agency where Securities of that series may be presented or surrendered for payment or, if
applicable, for conversion, where Securities of that series may be surrendered for registration of
transfer or exchange and where notices and demands to or upon the Company or any Subsidiary
Guarantor in respect of the Securities of that series or any Subsidiary Guarantee and this
Indenture may be served. 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 and each Subsidiary Guarantor hereby
appoints the Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

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

55

 

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

     If the Company or any Subsidiary Guarantor shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the principal of or any
premium or interest on any of the Securities of that series, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum sufficient to pay the principal and any premium and
interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as
herein provided and will promptly notify the Trustee of its action or failure so to act.

     Whenever the Company shall have one or more Paying Agents for any series of Securities, it
will, prior to 11:00 A.M., New York City time, on each due date of the principal of or any premium
or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay
such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to
act.

     The Company will cause each Paying Agent for any series of Securities other than the Trustee
to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the
Trustee, subject to the provisions of this Section, that such Paying Agent will (1) comply with the
provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2) during the
continuance of any default by the Company, the Subsidiary Guarantors, if applicable, or any other
obligor upon the Securities of that series in the making of any payment in respect of the
Securities of that series, upon the written request of the Trustee, forthwith pay to the Trustee
all sums held in trust by such Paying Agent for payment in respect of the Securities of that
series.

     The Company may at any time, for the purpose of obtaining the satisfaction and discharge of
this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay,
to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by
the Trustee upon the same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be
released from all further liability with respect to such money.

     Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of or any premium or interest on any Security of any series
and remaining unclaimed for two years after such principal, premium or interest has become due and
payable shall be paid to the Company on Company Request, or (if then held by the Company) 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 thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before
being required to make any such repayment, may at the expense of the Company cause to be published
once, in a newspaper published in the English language, customarily published on each Business Day
and of general circulation in The City of New York, New York, notice that such money remains
unclaimed and that, after a date specified therein,

56

 

which shall not be less than 30 days from the date of such publication, any unclaimed balance
of such money then remaining will be repaid to the Company.

SECTION 1004. Statement by Officers as to Default.

     (a) The Company and the Subsidiary Guarantors will deliver to the Trustee, within 90 days
after the end of each fiscal year of the Company ending after the date hereof, an Officers’
Certificate, stating whether or not to the best knowledge of the signers thereof the Company or any
Subsidiary Guarantor, as the case may be, is in default in the performance and observance of any of
the terms, provisions and conditions of this Indenture (without regard to any period of grace or
requirement of notice provided hereunder) and, if the Company or any Subsidiary Guarantor shall be
in default, specifying all such defaults and the nature and status thereof of which they may have
knowledge.

     (b) The Company and each Subsidiary Guarantor shall deliver to the Trustee, as soon as
possible and in any event within five days after the Company or such Subsidiary Guarantor becomes
aware or should reasonably become aware of the occurrence of an Event of Default or an event which,
with notice or the lapse of time or both, would constitute an Event of Default, an Officers’
Certificate setting forth the details of such Event of Default or default, and the action which the
Company or such Subsidiary Guarantor proposes to take with respect thereto.

SECTION 1005. Existence.

     Subject to Article Eight, the Company will do or cause to be done all things necessary to
preserve and keep in full force and effect the existence, rights (charter and statutory) and
franchises of the Company; provided, however, that the Company shall not be required to preserve
any such right or franchise if it shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company and that the loss thereof is not
disadvantageous in any material respect to the Holders.

SECTION 1006. Maintenance of Properties.

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

SECTION 1007. Payment of Taxes and Other Claims.

     The Company will pay or discharge or cause to be paid or discharged, before the same shall
become delinquent, (1) all taxes, assessments and governmental charges levied or imposed upon the
Company or any Subsidiary or upon the income, profits or property of the Company or

57

 

any Subsidiary, and (2) all lawful claims for labor, materials and supplies which, if unpaid,
might by law become a lien upon the property of the Company or any Subsidiary; provided, however,
that the Company shall not be required to pay or discharge or cause to be paid or discharged any
such tax, assessment, charge or claim whose amount, applicability or validity is being contested in
good faith by appropriate proceedings.

SECTION 1008. Maintenance of Insurance.

     The Company shall, and shall cause its Subsidiaries to, keep at all times all of their
properties which are of an insurable nature insured against loss or damage with insurers believed
by the Company to be responsible to the extent that property of similar character is usually so
insured by corporations similarly situated and owning like properties in accordance with good
business practice.

SECTION 1009. Waiver of Certain Covenants.

     Except as otherwise specified as contemplated by Section 301 for Securities of such series,
the Company may, with respect to the Securities of any series, omit in any particular instance to
comply with any term, provision or condition set forth in any of Sections 1005 through 1008 or in
any covenant provided pursuant to Section 301(20), 901(2) or 901(7) for the benefit of the Holders
of such series if before the time for such compliance the Holders of at least a majority in
principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such term, provision or
condition, but no such waiver shall extend to or affect such term, provision or condition except to
the extent so expressly waived, and, until such waiver shall become effective, the obligations of
the Company and the duties of the Trustee in respect of any such term, provision or condition shall
remain in full force and effect.

ARTICLE ELEVEN

REDEMPTION OF SECURITIES

SECTION 1101. Applicability of Article.

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

SECTION 1102. Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Securities shall be evidenced by a Board Resolution
or in another manner specified as contemplated by Section 301 for such Securities. In case of any
redemption at the election of the Company of less than all the Securities of any series (including
any such redemption affecting only a single Security), the Company shall, at least five Business
Days prior to giving notice of such redemption (unless a shorter notice shall be satisfactory to
the Trustee), notify the Trustee of such Redemption Date, of the principal amount of Securities of
such series to be redeemed and, if applicable, of the tenor of the

58

 

Securities to be redeemed. In the case of any redemption of Securities prior to the
expiration of any restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers’ Certificate
evidencing compliance with such restriction.

SECTION 1103. Selection by Trustee of Securities to Be Redeemed.

     If less than all the Securities of any series are to be redeemed (unless all the Securities of
such series and of a specified tenor are to be redeemed or unless such redemption affects only a
single Security), the particular Securities to be redeemed shall be selected by the Trustee, from
the Outstanding Securities of such series not previously called for redemption, (i) in compliance
with the requirements of the principal national securities exchange on which such Securities are
listed, if such Securities are listed on any national securities exchange, and (ii) if such
Securities are not so listed, on a pro rata basis, by lot or by such other method as the Trustee
shall deem fair and appropriate and which may provide for the selection for redemption of a portion
of the principal amount of any Security of such series, provided that the unredeemed portion of the
principal amount of any Security shall be in an authorized denomination (which shall not be less
than the minimum authorized denomination) for such Security. If less than all the Securities of
such series and of a specified tenor are to be redeemed (unless such redemption affects only a
single Security), the particular Securities to be redeemed shall be selected by the Trustee, from
the Outstanding Securities of such series and specified tenor not previously called for redemption
in accordance with the preceding sentence.

     The Trustee shall promptly notify the Company in writing of the Securities selected for
redemption as aforesaid and, in case of any Securities selected for partial redemption as
aforesaid, the principal amount thereof to be redeemed.

     The provisions of the two preceding paragraphs shall not apply with respect to any redemption
affecting only a single Security, whether such Security is to be redeemed in whole or in part. In
the case of any such redemption in part, the unredeemed portion of the principal amount of the
Security shall be in an authorized denomination (which shall not be less than the minimum
authorized denomination) for such Security.

     For all purposes of this Indenture, unless the context otherwise requires, all provisions
relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to
be redeemed only in part, to the portion of the principal amount of such Securities which has been
or is to be redeemed. If any Security selected for partial redemption is surrendered for
conversion after such selection, the converted portion of such Security shall be deemed (so far as
may be) to be the portion selected for redemption. Upon any redemption of less than all the
Securities of a series, for purposes of selection for redemption the Company and the Trustee may
treat as Outstanding Securities surrendered for conversion during the period of 15 days next
preceding the mailing of a notice of redemption, and need not treat as Outstanding any Security
authenticated and delivered during such period in exchange for the unconverted portion of any
Security converted in part during such period.

59

 

SECTION 1104. Notice of Redemption.

     Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than
30 nor more than 60 days prior to the Redemption Date (except that redemption notices may be mailed
more than 60 days prior to a Redemption Date if the notice is issued in connection with a
satisfaction and discharge pursuant to Article Four, a Defeasance or a Covenant Defeasance), to
each Holder of Securities to be redeemed, at his address appearing in the Security Register;
provided, however, notice of redemption may be given more than 60 days prior to the Redemption Date
if the notice is issued in connection with a satisfaction and discharge pursuant to Article Four.

     All notices of redemption shall state:

     (1) the Redemption Date,

     (2) the Redemption Price, if then determinable and otherwise the method of its
determination,

     (3) if less than all the Outstanding Securities of any series consisting of more than a
single Security are to be redeemed, the identification (and, in the case of partial
redemption of any such Securities, the principal amounts) of the particular Securities to be
redeemed and, if less than all the Outstanding Securities of any series consisting of a
single Security are to be redeemed, the principal amount of the particular Security to be
redeemed,

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

     (5) the place or places where each such Security is to be surrendered for payment of
the Redemption Price,

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

     (7) if applicable, the conversion price then in effect and the date on which the right
to convert such Securities will expire.

     Notice of redemption of Securities to be redeemed at the election of the Company shall be
given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of
the Company and shall be irrevocable. If any Security called for redemption is converted pursuant
hereto, any money deposited with the Trustee or any Paying Agent or so segregated and held in trust
for the redemption of such Security shall be paid to the Company upon delivery of a Company Request
to the Trustee or such Paying Agent, or, if then held by the Company, shall be discharged from such
trust.

60

 

SECTION 1105. Deposit of Redemption Price.

     Prior to 11:00 A.M., New York City time, on any Redemption Date, the Company shall deposit
with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the
Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued
interest on, all the Securities which are to be redeemed on that date.

SECTION 1106. Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall,
on the Redemption Date, become due and payable at the Redemption Price therein specified, and from
and after such date (unless the Company shall default in the payment of the Redemption Price and
accrued interest) such Securities shall cease to bear interest. Upon surrender of any such
Security for redemption in accordance with said notice, such Security shall be paid by the Company
at the Redemption Price, together with accrued interest to the Redemption Date; provided, however,
that, unless otherwise specified as contemplated by Section 301, installments of interest whose
Stated Maturity is on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the close of business on
the relevant Record Dates according to their terms and the provisions of Section 307.

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

SECTION 1107. Securities Redeemed in Part.

     Any Security which is to be redeemed only in part shall be surrendered at a Place of Payment
therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the
Holder thereof or his attorney duly authorized in writing), and the Company shall execute, if
applicable to Subsidiary Guarantors shall execute the Subsidiary Guarantee endorsed thereon, and
the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a
new Security or Securities of the same series and of like tenor, of any authorized denomination as
requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed
portion of the principal of the Security so surrendered.

ARTICLE TWELVE

SUBORDINATION OF SECURITIES

SECTION 1201. Applicability of Article.

     Unless otherwise provided with respect to the Securities of any series in or pursuant to the
Board Resolution or supplemental indenture establishing such series of Securities pursuant to
Section 301, the provisions of this Article shall be applicable to each series of Securities.

61

 

SECTION 1202. Securities Subordinate to Senior Debt.

     The Company covenants and agrees, and each Holder of a Security, by his acceptance thereof,
likewise covenants and agrees, that, to the extent and in the manner hereinafter set forth in this
Article (subject to the provisions of Article Four and Article Fifteen), the payment of the
principal of (and premium, if any) and interest on each and all of the Securities of such series
are hereby expressly made subordinate and subject in right of payment to the prior payment in full
of all Senior Debt of the Company.

     No provisions of this Article Twelve shall prevent the occurrence of any Event of Default.

SECTION 1203. Payment Over of Proceeds Upon Dissolution, Etc.

     In the event of (a) any insolvency or bankruptcy case or proceeding, or any receivership,
liquidation, reorganization or other similar case or proceeding in connection therewith, relative
to the Company or to its creditors, as such, or to its assets, or (b) any liquidation, dissolution
or other winding up of the Company, whether voluntary or involuntary and whether or not involving
insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or any other
marshalling of assets and liabilities of the Company, then and in any such event specified in (a),
(b) or (c) above (each such event, if any, herein sometimes referred to as a “Proceeding”) the
holders of Senior Debt of the Company shall be entitled to receive payment in full of all amounts
due or to become due on or in respect of all Senior Debt of the Company, or provision shall be made
for such payment in cash or cash equivalents or otherwise in a manner satisfactory to the holders
of Senior Debt of the Company, before the Holders of the Securities are entitled to receive any
payment or distribution of any kind or character, whether in cash, property or securities
(including any payment or distribution which may be payable or deliverable by reason of the payment
of any other indebtedness of the Company subordinated to the payment of the Securities, such
payment or distribution being hereinafter referred to as a “Junior Subordinated Payment”), on
account of principal of (or premium, if any) or interest on the Securities or on account of any
purchase or other acquisition of Securities by the Company or any Subsidiary of the Company (all
such payments, distributions, purchases and acquisitions, other than the payment or distribution of
stock or securities of the Company referred to in the second succeeding paragraph, herein referred
to, individually and collectively, as a “Securities Payment”), and to that end the holders of
Senior Debt of the Company shall be entitled to receive, for application to the payment thereof,
any Securities Payment which may be payable or deliverable in respect of the Securities in any such
Proceeding.

     In the event that, notwithstanding the foregoing provisions of this Section, the Trustee or
the Holder of any Security shall have received any Securities Payment before all Senior Debt of the
Company is paid in full or payment thereof provided for in cash or cash equivalents or otherwise in
a manner satisfactory to the holders of Senior Debt of the Company, and if such fact shall, at or
prior to the time of such Securities Payment, have been made known to the Trustee or, as the case
may be, such Holder, then and in such event such Securities Payment shall be paid over or delivered
forthwith to the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee, agent
or other Person making payment or distribution of assets of the Company for application to the
payment of all Senior Debt of the Company remaining unpaid, to the extent

62

 

necessary to pay all Senior Debt of the Company in full, after giving effect to any concurrent
payment or distribution to or for the holders of Senior Debt of the Company.

     For purposes of this Article only, the words “any payment or distribution of any kind or
character, whether in cash, property or securities” shall not be deemed to include a payment or
distribution of stock or securities of the Company provided for by a plan of reorganization or
readjustment authorized by an order or decree of a court of competent jurisdiction in a
reorganization proceeding under any applicable bankruptcy law or of any other corporation provided
for by such plan of reorganization or readjustment which stock or securities are subordinated in
right of payment to all then outstanding Senior Debt of the Company to substantially the same
extent as the Securities are so subordinated as provided in this Article. The consolidation of the
Company with, or the merger of the Company into, another Person or the liquidation or dissolution
of the Company following the conveyance or transfer of all or substantially all of its assets to
another Person upon the terms and conditions set forth in Article Eight shall not be deemed a
Proceeding for the purposes of this Section if the Person formed by such consolidation or into
which the Company is merged or the Person which acquires by conveyance or transfer such assets, as
the case may be, shall, as a part of such consolidation, merger, conveyance or transfer, comply
with the conditions set forth in Article Eight.

SECTION 1204. No Payment When Senior Debt of the Company in Default.

     In the event that any Senior Payment Default (as defined below) shall have occurred and be
continuing, then no Securities Payment shall be made unless and until such Senior Payment Default
shall have been cured or waived or shall have ceased to exist or all amounts then due and payable
in respect of Senior Debt of the Company shall have been paid in full, or provision shall have been
made for such payment in cash or cash equivalents or otherwise in a manner satisfactory to the
holders of Senior Debt of the Company; provided, however, that nothing in this Section shall
prevent the satisfaction of any sinking fund payment in accordance with Article Sixteen by
delivering and crediting pursuant to Section 1602 Securities which have been acquired (upon
redemption or otherwise) prior to such Senior Payment Default.

     “Senior Payment Default” means any default in the payment of principal of (or premium,
if any) or interest on any Senior Debt of the Company when due, whether at the Stated
Maturity of any such payment or by declaration of acceleration, call for redemption or
otherwise.

     In the event that any Senior Nonmonetary Default (as defined below) shall have occurred and be
continuing, then, upon the receipt by the Company, the Subsidiary Guarantors and the Trustee of
written notice of such Senior Nonmonetary Default from the agent for the Designated Senior Debt
which is the subject of such Senior Nonmonetary Default, no Securities Payment shall be made during
the period (the “Payment Blockage Period”) commencing on the date of such receipt of such written
notice and ending on the earlier of (i) the date on which such Senior Nonmonetary Default shall
have been cured or waived or shall have ceased to exist or all Designated Senior Debt the subject
of such Senior Nonmonetary Default shall have been discharged; (ii) the 179th day after the date of
such receipt of such written notice; or (iii) the date on which the Payment Blockage Period shall
have been terminated by written notice to the Company, any Subsidiary Guarantor or the Trustee from
the agent for the Designated Senior

63

 

Debt initiating the Payment Blockage Period; provided, however, that nothing in this Section
shall prevent the satisfaction of any sinking fund payment in accordance with Article Sixteen by
delivering and crediting pursuant to Section 1602 Securities which have been acquired (upon
redemption or otherwise) prior to the date of such receipt of such written notice. No more than
one Payment Blockage Period may be commenced with respect to the Securities of a particular series
during any 360-day period and there shall be a period of at least 181 consecutive days in each
360-day period when no Payment Blockage Period is in effect. For all purposes of this paragraph,
no Senior Nonmonetary Default that existed or was continuing on the date of commencement of any
Payment Blockage Period shall be, or be made, the basis for the commencement of a subsequent
Payment Blockage Period, whether or not within a period of 360 consecutive days, unless such Senior
Nonmonetary Default shall have been cured for a period of not less than 90 consecutive days.

     “Senior Nonmonetary Default” means the occurrence or existence and continuance of any event of
default with respect to any Designated Senior Debt, other than a Senior Payment Default, permitting
the holders of such Designated Senior Debt (or a trustee or agent on behalf of the holders thereof)
to declare such Designated Senior Debt due and payable prior to the date on which it would
otherwise become due and payable.

     In the event that, notwithstanding the foregoing, the Company shall make any Securities
Payment to the Trustee or any Holder prohibited by the foregoing provisions of this Section, and if
such fact shall, at or prior to the time of such Securities Payment, have been made known to the
Trustee or, as the case may be, such Holder, then and in such event such Securities Payment shall
be paid over and delivered forthwith to the Company.

     The provisions of this Section shall not apply to any Securities Payment with respect to which
Section 1203 would be applicable.

SECTION 1205. Payment Permitted If No Default.

     Nothing contained in this Article or elsewhere in this Indenture or in any of the Securities
shall prevent (a) the Company, at any time except during the pendency of any Proceeding referred to
in Section 1203 or under the conditions described in Section 1204, from making Securities Payments,
or (b) the application by the Trustee of any money deposited with it hereunder to Securities
Payments or the retention of such Securities Payment by the Holders, if, at the time of such
application by the Trustee, it did not have knowledge that such Securities Payment would have been
prohibited by the provisions of this Article.

SECTION 1206. Subrogation to Rights of Holders of Senior Debt of the Company.

     Subject to the payment in full of all amounts due or to become due on or in respect of Senior
Debt of the Company, or the provision for such payment in cash or cash equivalents or otherwise in
a manner satisfactory to the holders of Senior Debt of the Company, the Holders of the Securities
shall be subrogated to the rights of the holders of such Senior Debt of the Company to receive
payments and distributions of cash, property and securities applicable to the Senior Debt of the
Company until the principal of (and premium, if any) and interest on the Securities shall be paid
in full. For purposes of such subrogation, no payments or distributions to

64

 

the holders of the Senior Debt of the Company of any cash, property or securities to which the
Holders of the Securities or the Trustee would be entitled except for the provisions of this
Article, and no payments over pursuant to the provisions of this Article to the holders of Senior
Debt of the Company by Holders of the Securities or the Trustee, shall, as among the Company, its
creditors other than holders of Senior Debt of the Company and the Holders of the Securities, be
deemed to be a payment or distribution by the Company to or on account of the Senior Debt of the
Company.

SECTION 1207. Provisions Solely to Define Relative Rights.

     The provisions of this Article are and are intended solely for the purpose of defining the
relative rights of the Holders on the one hand and the holders of Senior Debt of the Company on the
other hand. Nothing contained in this Article or elsewhere in this Indenture or in the Securities
is intended to or shall (a) impair, as among the Company, its creditors other than holders of
Senior Debt of the Company and the Holders of the Securities, the obligation of the Company, which
is absolute and unconditional (and which, subject to the rights under this Article of the holders
of Senior Debt of the Company, is intended to rank equally with all other general obligations of
the Company), to pay to the Holders of the Securities the principal of (and premium, if any) and
interest on the Securities as and when the same shall become due and payable in accordance with
their terms; or (b) affect the relative rights against the Company of the Holders of the Securities
and creditors of the Company other than the holders of Senior Debt of the Company; or (c) 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
of the holders of Senior Debt of the Company to receive cash, property and securities otherwise
payable or deliverable to the Trustee or such Holder.

SECTION 1208. Trustee to Effectuate Subordination.

     Each Holder of a Security by his acceptance thereof authorizes and directs the Trustee on his
behalf to take such action as may be necessary or appropriate to effectuate the subordination
provided in this Article and appoints the Trustee his attorney-in-fact for any and all such
purposes.

SECTION 1209. No Waiver of Subordination Provisions.

     No right of any present or future holder of any Senior Debt of the Company to enforce
subordination as herein provided shall at any time in any way be prejudiced or impaired by any act
or failure to act on the part of the Company or by any act or failure to act, in good faith, by any
such holder, or by any noncompliance by the Company with the terms, provisions and covenants of
this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise
charged with.

     Without in any way limiting the generality of the foregoing paragraph, the holders of Senior
Debt of the Company may, at any time and from time to time, without the consent of or notice to the
Trustee or the Holders of the Securities, without incurring responsibility to the Holders of the
Securities and without impairing or releasing the subordination provided in this Article or the
obligations hereunder of the Holders of the Securities to the holders of Senior Debt

65

 

of the Company, do any one or more of the following: (i) change the manner, place or terms of
payment or extend the time of payment of, or renew or alter, Senior Debt of the Company, or
otherwise amend or supplement in any manner Senior Debt of the Company or any instrument evidencing
the same or any agreement under which Senior Debt of the Company is outstanding; (ii) sell,
exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing
Senior Debt of the Company; (iii) release any Person liable in any manner for the collection of
Senior Debt of the Company; and (iv) exercise or refrain from exercising any rights against the
Company and any other Person.

SECTION 1210. Notice to Trustee.

     The Company shall give prompt written notice to the Trustee of any fact known to the Company
which would prohibit the making of any payment to or by the Trustee in respect of the Securities.
Notwithstanding the provisions of this Article or any other provision of this Indenture, the
Trustee shall not be charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, unless and until the
Trustee shall have received written notice thereof from the Company or a holder of Senior Debt of
the Company or from any trustee therefor; and, prior to the receipt of any such written notice, the
Trustee, subject to the provisions of Section 601, shall be entitled in all respects to assume that
no such facts exist; provided, however, that if the Trustee shall not have received the notice
provided for in this Section at least three Business Days prior to the date upon which by the terms
hereof any money may become payable for any purpose (including, without limitation, the payment of
the principal of (and premium, if any) or interest on any Security), then, anything herein
contained to the contrary notwithstanding, the Trustee shall have full power and authority to
receive such money and to apply the same to the purpose for which such money was received and shall
not be affected by any notice to the contrary which may be received by it within three Business
Days prior to such date.

     Subject to the provisions of Section 601, 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 Debt
of the Company (or a trustee therefor) to establish that such notice has been given by a holder of
Senior Debt of the Company (or a trustee therefor). 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 Debt of the Company to participate in any payment or distribution pursuant to this Article,
the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the
Trustee as to the amount of Senior Debt of the Company 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, 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 1211. Reliance on Judicial Order or Certificate of Liquidating Agent.

     Upon any payment or distribution of assets of the Company referred to in this Article, the
Trustee, subject to the provisions of Section 601, and the Holders of the Securities shall be
entitled to rely upon any order or decree entered by any court of competent jurisdiction in which
such Proceeding is pending, or a certificate of the trustee in bankruptcy, receiver, liquidating

66

 

trustee, custodian, 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
the Senior Debt of the Company 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.

SECTION 1212. Trustee Not Fiduciary for Holders of Senior Debt of the Company.

     The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt of the
Company and shall not be liable to any such holders if it shall in good faith mistakenly pay over
or distribute to Holders of Securities or to the Company, a Subsidiary Guarantor or to any other
Person cash, property or securities to which any holders of Senior Debt of the Company shall be
entitled by virtue of this Article or otherwise.

SECTION 1213. Rights of Trustee as Holder of Senior Debt of the Company; Preservation of Trustee’s
Rights.

     The Trustee in its individual capacity shall be entitled to all the rights set forth in this
Article with respect to any Senior Debt of the Company which may at any time be held by it, to the
same extent as any other holder of Senior Debt of the Company, and nothing in this Indenture shall
deprive the Trustee of any of its rights as such holder.

     Nothing in this Article shall apply to claims of, or payments to, the Trustee under or
pursuant to Section 607.

SECTION 1214. Article Applicable to Paying Agents.

     In case at any time any Paying Agent other than the Trustee shall have been appointed by the
Company and be then acting hereunder, the term “Trustee” as used in this Article shall in such case
(unless the context otherwise requires) be construed as extending to and including such Paying
Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named
in this Article in addition to or in place of the Trustee; provided, however, that Section 1213
shall not apply to the Company, any Subsidiary Guarantor or any Affiliate of the Company if it or
such Subsidiary Guarantor or Affiliate acts as Paying Agent.

SECTION 1215. Defeasance of this Article Twelve.

     The subordination of the Securities of a series provided by this Article Twelve is expressly
made subject to the provisions for Defeasance or Covenant Defeasance in Article Fifteen hereof and,
anything herein to the contrary notwithstanding, upon the effectiveness of any such Defeasance or
Covenant Defeasance, the Securities of such series then outstanding shall thereupon cease to be
subordinated pursuant to this Article Twelve.

67

 

ARTICLE THIRTEEN

SUBSIDIARY GUARANTEES

SECTION 1301. Applicability of Article.

     If the Company elects to issue any series of Securities with the benefit of Subsidiary
Guarantees, such election shall be evidenced in or pursuant to the Board Resolution or supplemental
indenture establishing such series of Securities pursuant to Section 301 and the provisions of this
Article shall be applicable to each such series of Securities except as otherwise specified in or
pursuant to the Board Resolution or supplemental indenture establishing such series pursuant to
Section 301.

SECTION 1302. Subsidiary Guarantees.

     Subject to Section 1301, each Subsidiary Guarantor hereby, jointly and severally, fully and
unconditionally guarantees to each Holder of a Security authenticated and delivered by the Trustee,
the due and punctual payment of the principal of (and premium, if any) and interest on such
Security when and as the same shall become due and payable, whether at the Stated Maturity, by
acceleration, call for redemption, offer to purchase or otherwise, in accordance with the terms of
such Security and of this Indenture, and each Subsidiary Guarantor similarly guarantees to the
Trustee the payment of all amounts owing to the Trustee in accordance with the terms of this
Indenture. In case of the failure of the Company punctually to make any such payment, each
Subsidiary Guarantor hereby, jointly and severally, agrees to cause such payment to be made
punctually when and as the same shall become due and payable, whether at the Stated Maturity or by
acceleration, call for redemption, offer to purchase or otherwise, and as if such payment were made
by the Company.

     Each of the Subsidiary Guarantors hereby jointly and severally agrees that its obligations
hereunder shall be absolute, unconditional, irrespective of, and shall be unaffected by, the
validity, regularity or enforceability of such Security or this Indenture, the absence of any
action to enforce the same or any release, amendment, waiver or indulgence granted to the Company
or any guarantor or any consent to departure from any requirement of any other guarantee of all or
any of the Securities of such series or any other circumstances which might otherwise constitute a
legal or equitable discharge or defense of a surety or guarantor; provided, however, that,
notwithstanding the foregoing, no such release, amendment, waiver or indulgence shall, without the
consent of such Subsidiary Guarantor, increase the principal amount of such Security, or increase
the interest rate thereon, or alter the Stated Maturity thereof. Each of the Subsidiary Guarantors
hereby waives the benefits of diligence, presentment, demand for payment, any requirement that the
Trustee or any of the Holders protect, secure, perfect or insure any security interest in or other
lien on any property subject thereto or exhaust any right or take any action against the Company or
any other Person or any collateral, filing of claims with a court in the event of insolvency or
bankruptcy of the Company, any right to require a proceeding first against the Company, protest or
notice with respect to such Security or the indebtedness evidenced thereby and all demands
whatsoever, and covenants that this Subsidiary Guarantee will not be discharged in respect of such
Security except by complete performance of the obligations contained in such Security and in such
Subsidiary Guarantee. Each Subsidiary Guarantor agrees

68

 

that if, after the occurrence and during the continuance of an Event of Default, the Trustee
or any of the Holders are prevented by applicable law from exercising their respective rights to
accelerate the maturity of the Securities of a series, to collect interest on the Securities of a
series, or to enforce or exercise any other right or remedy with respect to the Securities of a
series, such Subsidiary Guarantor agrees to pay to the Trustee for the account of the Holders, upon
demand therefor, the amount that would otherwise have been due and payable had such rights and
remedies been permitted to be exercised by the Trustee or any of the Holders.

     The indebtedness of each Subsidiary Guarantor evidenced by the Subsidiary Guarantees is, to
the extent provided in this Indenture, subordinate and subject in right of payment to the prior
payment in full of all Senior Debt of each Subsidiary Guarantor, and the Subsidiary Guarantees are
issued subject to the provisions of this Indenture with respect thereto. Each Holder of such
Security, by accepting the same, will be deemed to have (a) agreed to and be bound by such
provisions, (b) authorized and directed the Trustee on his behalf to take such action as may be
necessary or appropriate to effectuate the subordination so provided and (c) appointed the Trustee
his attorney-in-fact for any and all such purposes.

     Each Subsidiary Guarantor shall be subrogated to all rights of the Holders of the Securities
upon which its Subsidiary Guarantee is endorsed against the Company in respect of any amounts paid
by such Subsidiary Guarantor on account of such Security pursuant to the provisions of its
Subsidiary Guarantee or this Indenture; provided, however, that no Subsidiary Guarantor shall be
entitled to enforce or to receive any payments arising out of, or based upon, such right of
subrogation until the principal of (and premium, if any) and interest on all Securities of the
relevant series issued hereunder shall have been paid in full.

     Each Subsidiary Guarantor that makes or is required to make any payment in respect of its
Subsidiary Guarantee shall be entitled to seek contribution from the other Subsidiary Guarantors to
the extent permitted by applicable law; provided, however, that no Subsidiary Guarantor shall be
entitled to enforce or receive any payments arising out of, or based upon, such right of
contribution until the principal of (and premium, if any) and interest on all Securities of the
relevant series issued hereunder shall have been paid in full.

     Each Subsidiary Guarantee shall remain in full force and effect and continue to be effective
should any petition be filed by or against the Company for liquidation or reorganization, should
the Company become insolvent or make an assignment for the benefit of creditors or should a
receiver or trustee be appointed for all or any part of the Company’s assets, and shall, to the
fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if
at any time payment and performance of the Securities of a series, is, pursuant to applicable law,
rescinded or reduced in amount, or must otherwise be restored or returned by any Holder of the
Securities, whether as a “voidable preference”, “fraudulent transfer”, or otherwise, all as though
such payment or performance had not been made. In the event that any payment, or any part thereof,
is rescinded, reduced, restored or returned, the Securities shall, to the fullest extent permitted
by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced,
restored or returned.

69

 

SECTION 1303. Execution and Delivery of Subsidiary Guarantees.

     The Subsidiary Guarantees to be endorsed on the Securities shall include the terms of the
Subsidiary Guarantee set forth in Section 1302 and any other terms that may be set forth in the
form established pursuant to Section 204. Subject to Section 1301, each of the Subsidiary
Guarantors hereby agrees to execute its Subsidiary Guarantee, in a form established pursuant to
Section 204, to be endorsed on each Security authenticated and delivered by the Trustee.

     The Subsidiary Guarantee shall be executed on behalf of each respective Subsidiary Guarantor
by any one of such Subsidiary Guarantor’s Chairman of the Board of Directors, Vice Chairman of the
Board of Directors, Chief Executive Officer, President, one of its Vice Presidents, or its
Secretary. The signature of any or all of these persons on the Subsidiary Guarantee may be manual
or facsimile.

     A Subsidiary Guarantee bearing the manual or facsimile signature of individuals who were at
any time the proper officers of a Subsidiary Guarantor shall bind such Subsidiary Guarantor,
notwithstanding that such individuals or any of them have ceased to hold such offices prior to the
authentication and delivery of the Security on which such Subsidiary Guarantee is endorsed or did
not hold such offices at the date of such Subsidiary Guarantee.

     The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall
constitute due delivery of the Subsidiary Guarantee endorsed thereon on behalf of the Subsidiary
Guarantors and shall bind each Subsidiary Guarantor notwithstanding the fact that Subsidiary
Guarantee does not bear the signature of such Subsidiary Guarantor. Each of the Subsidiary
Guarantors hereby jointly and severally agrees that its Subsidiary Guarantee set forth in Section
1302 and in the form of Subsidiary Guarantee established pursuant to Section 204 shall remain in
full force and effect notwithstanding any failure to endorse a Subsidiary Guarantee on any
Security.

SECTION 1304. Release of Subsidiary Guarantors.

     Unless otherwise specified pursuant to Section 301 with respect to a series of Securities,
each Subsidiary Guarantee will remain in effect with respect to the respective Subsidiary Guarantor
until the entire principal of, premium, if any, and interest on the Securities to which such
Subsidiary Guarantee relates shall have been paid in full or otherwise satisfied and discharged in
accordance with the provisions of such Securities and this Indenture and all amounts owing to the
Trustee hereunder have been paid; provided, however, that if (i) such Subsidiary Guarantor ceases
to be a Subsidiary in compliance with the applicable provisions of this Indenture, (ii) either
Defeasance or Covenant Defeasance occurs with respect to such Securities pursuant to Article
Fifteen or (iii) all or substantially all of the assets of such Subsidiary Guarantor or all of the
Capital Stock of such Subsidiary Guarantor is sold (including by sale, merger, consolidation or
otherwise) by the Company or any Subsidiary in a transaction complying with the requirements of
this Indenture, then, in each case of (i), (ii) or (iii), upon delivery by the Company of an
Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent herein
provided for relating to the release of such Subsidiary Guarantor from its obligations under its
Subsidiary Guarantee and this Article Thirteen have been complied with, such Subsidiary Guarantor
shall be released and discharged of its obligations under its

70

 

Subsidiary Guarantee and under this Article Thirteen without any action on the part of the
Trustee or any Holder, and the Trustee shall execute any documents reasonably required in order to
acknowledge the release of such Subsidiary Guarantor from its obligations under its Subsidiary
Guarantee endorsed on the Securities of such series and under this Article Thirteen.

SECTION 1305. Additional Subsidiary Guarantors.

     If so specified pursuant to Section 301 with respect to a series of Securities, the Company
will cause any domestic Subsidiary of the Company that becomes a Subsidiary after the date the
Securities of a series are first issued hereunder to become a Subsidiary Guarantor as soon as
practicable after such Subsidiary becomes a Subsidiary. The Company shall cause any such
Subsidiary to become a Subsidiary Guarantor with respect to the Securities by executing and
delivering to the Trustee (a) a supplemental indenture, in form and substance satisfactory to the
Trustee, which subjects such Person to the provisions (including the representations and
warranties) of this Indenture as a Subsidiary Guarantor and (b) an Opinion of Counsel to the effect
that such supplemental indenture has been duly authorized and executed by such Person and such
supplemental indenture and such Person’s obligations under its Subsidiary Guarantee and this
Indenture constitute the legal, valid, binding and enforceable obligations of such Person (subject
to such customary exceptions concerning creditors’ rights and equitable principles as may be
acceptable to the Trustee in its discretion).

SECTION 1306. Limitation on Liability.

     Any term or provision of this Indenture to the contrary notwithstanding, the maximum amount of
the Subsidiary Guarantee of any Subsidiary Guarantor shall not exceed the maximum amount that can
be hereby guaranteed by such Subsidiary Guarantor without rendering such Subsidiary Guarantee
voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar
laws affecting the rights of creditors generally.

ARTICLE FOURTEEN

SUBORDINATION OF SUBSIDIARY GUARANTEES

SECTION 1401. Applicability of Article.

     Unless otherwise provided with respect to the Securities of any series in or pursuant to the
Board Resolution or supplemental indenture establishing Subsidiary Guarantees for such series of
Securities pursuant to Section 301, the provisions of this Article shall be applicable to each
series of Securities.

SECTION 1402. Subsidiary Guarantees Subordinate to Senior Debt of Subordinate Guarantors.

     Each Subsidiary Guarantor covenants and agrees, and each Holder of a Security, by his
acceptance thereof, likewise covenants and agrees, that, to the extent and in the manner
hereinafter set forth in this Article (subject to the provisions of Article Four and Article
Fifteen), the Subsidiary Guarantee of such Subsidiary Guarantor is hereby expressly made
subordinate

71

 

and subject in right of payment to the prior payment in full of all Senior Debt of such
Subsidiary Guarantor.

     No provisions of this Article Fourteen shall prevent the occurrence of any Event of Default.

SECTION 1403. Payment Over of Proceeds Upon Dissolution, Etc.

     In the event of (a) any insolvency or bankruptcy case or proceeding, or any receivership,
liquidation, reorganization or other similar case or proceeding in connection therewith, relative
to any Subsidiary Guarantor or to its creditors, as such, or to its assets, or (b) any liquidation,
dissolution or other winding up of any Subsidiary Guarantor, whether voluntary or involuntary and
whether or not involving insolvency or bankruptcy, or (c) any assignment for the benefit of
creditors or any other marshalling of assets and liabilities of any Subsidiary Guarantor, then and
in any such event specified in (a), (b) or (c) above (each such event, if any, herein sometimes
referred to as a “Guarantor Proceeding”) the holders of Senior Debt of such Subsidiary Guarantor
shall be entitled to receive payment in full of all amounts due or to become due on or in respect
of all Senior Debt of such Subsidiary Guarantor, or provision shall be made for such payment in
cash or cash equivalents or otherwise in a manner satisfactory to the holders of Senior Debt of
such Subsidiary Guarantor, before the Holders of the Securities are entitled to receive any payment
or distribution of any kind or character, whether in cash, property or securities (including any
payment or distribution which may be payable or deliverable by reason of the payment of any other
indebtedness of such Subsidiary Guarantor subordinated to the payment of the Securities, such
payment or distribution being hereinafter referred to as a “Guarantor Junior Subordinated
Payment”), on account of the Subsidiary Guarantee of such Subsidiary Guarantor (all such payments,
other than the payment or distribution of stock or securities of a Subsidiary Guarantor referred to
in the second succeeding paragraph, herein referred to, individually and collectively, as a
“Guarantee Payment”), and to that end the holders of Senior Debt of such Subsidiary Guarantor shall
be entitled to receive, for application to the payment thereof, any Guarantee Payment which may be
payable or deliverable in respect of such Subsidiary Guarantor’s Subsidiary Guarantee in any such
Guarantor Proceeding.

     In the event that, notwithstanding the foregoing provisions of this Section, the Trustee or
the Holder of any Security shall have received any Guarantee Payment before all Senior Debt of such
Subsidiary Guarantor is paid in full or payment thereof provided for in cash or cash equivalents or
otherwise in a manner satisfactory to the holders of Senior Debt of such Subsidiary Guarantor, and
if such fact shall, at or prior to the time of such Guarantee Payment, have been made known to the
Trustee or, as the case may be, such Holder, then and in such event such Guarantee Payment shall be
paid over or delivered forthwith to the trustee in bankruptcy, receiver, liquidating trustee,
custodian, assignee, agent or other Person making payment or distribution of assets of such
Subsidiary Guarantor for application to the payment of all Senior Debt of such Subsidiary Guarantor
remaining unpaid, to the extent necessary to pay all Senior Debt of such Subsidiary Guarantor in
full, after giving effect to any concurrent payment or distribution to or for the holders of Senior
Debt of such Subsidiary Guarantor.

     For purposes of this Article only, the words “any payment or distribution of any kind or
character, whether in cash, property or securities” shall not be deemed to include a payment or

72

 

distribution of stock or securities of a Subsidiary Guarantor provided for by a plan of
reorganization or readjustment authorized by an order or decree of a court of competent
jurisdiction in a reorganization proceeding under any applicable bankruptcy law or of any other
corporation provided for by such plan of reorganization or readjustment which stock or securities
are subordinated in right of payment to all then outstanding Senior Debt of such Subsidiary
Guarantor to substantially the same extent as the Subsidiary Guarantees are so subordinated as
provided in this Article. The consolidation of a Subsidiary Guarantor with, or the merger of a
Subsidiary Guarantor into, another Person or the liquidation or dissolution of such Subsidiary
Guarantor following the conveyance or transfer of all or substantially all of its assets to another
Person upon the terms and conditions set forth in Article Eight shall not be deemed a Guarantor
Proceeding for the purposes of this Section if the Person formed by such consolidation or into
which such Subsidiary Guarantor is merged or the Person which acquires by conveyance or transfer
such assets, as the case may be, shall, as a part of such consolidation, merger, conveyance or
transfer, comply with the conditions set forth in Article Eight.

SECTION 1404. No Payment When Senior Debt of such Subsidiary Guarantor in Default.

     In the event that any Senior Payment Default shall have occurred and be continuing, then no
Guarantee Payment shall be made unless and until such Senior Payment Default shall have been cured
or waived or shall have ceased to exist or all amounts then due and payable in respect of the
relevant Senior Debt of the Company shall have been paid in full, or provision shall have been made
for such payment in cash or cash equivalents or otherwise in a manner satisfactory to the holders
of such Senior Debt; provided, that nothing in this Section shall prevent the satisfaction of any
sinking fund payment in accordance with Article Sixteen by delivering and crediting pursuant to
Section 1602 Securities which have been acquired (upon redemption or otherwise) prior to such
Senior Payment Default.

     In the event that any Senior Nonmonetary Default shall have occurred and be continuing, then,
upon the receipt by the Company, the Subsidiary Guarantors and the Trustee of written notice of
such Senior Nonmonetary Default from any holder, or agent for the holders, of any Designated Senior
Debt of the Company, no Guarantee Payment shall be made during the applicable Payment Blockage
Period; provided, however, that nothing in this Section shall prevent the satisfaction of any
sinking fund payment in accordance with Article Sixteen by delivering and crediting pursuant to
Section 1602 Securities which have been acquired (upon redemption or otherwise) prior to the date
of such receipt of such written notice. No more than one Payment Blockage Period may be commenced
with respect to the Subsidiary Guarantees during any 360-day period and there shall be a period of
at least 181 consecutive days in each 360-day period when no Payment Blockage Period is in effect.
For all purposes of this paragraph, no Senior Nonmonetary Default that existed or was continuing on
the date of commencement of any Payment Blockage Period shall be, or be made, the basis for the
commencement of a subsequent Payment Blockage Period, whether or not within a period of 360
consecutive days, unless such Senior Nonmonetary Default shall have been cured for a period of not
less than 90 consecutive days.

     In the event that, notwithstanding the foregoing, a Subsidiary Guarantor shall make any
Guarantee Payment to the Trustee or any Holder prohibited by the foregoing provisions of this
Section, and if such fact shall, at or prior to the time of such Guarantee Payment, have been

73

 

made known to the Trustee or, as the case may be, such Holder, then and in such event such
Guarantee Payment shall be paid over and delivered forthwith to the Company.

     The provisions of this Section shall not apply to any Guarantee Payment with respect to which
Section 1403 would be applicable.

SECTION 1405. Payment Permitted If No Default.

     Nothing contained in this Article or elsewhere in this Indenture or in any of the Subsidiary
Guarantees shall prevent (a) a Subsidiary Guarantor, at any time except during the pendency of any
Guarantor Proceeding referred to in Section 1403 or under the conditions described in Section 1404,
from making Guarantee Payments, or (b) the application by the Trustee of any money deposited with
it hereunder to Guarantee Payments or the retention of such Guarantee Payment by the Holders, if,
at the time of such application by the Trustee, it did not have knowledge that such Guarantee
Payment would have been prohibited by the provisions of this Article.

SECTION 1406. Subrogation to Rights of Holders of Senior Debt of such Subsidiary Guarantor.

     Subject to the payment in full of all amounts due or to become due on or in respect of Senior
Debt of a Subsidiary Guarantor, or the provision for such payment in cash or cash equivalents or
otherwise in a manner satisfactory to the holders of Senior Debt of such Subsidiary Guarantor, the
Holders of the Securities shall be subrogated to the rights of the holders of such Senior Debt of
such Subsidiary Guarantor to receive payments and distributions of cash, property and securities
applicable to the Senior Debt of such Subsidiary Guarantor until the principal of (and premium, if
any) and interest on the Securities shall be paid in full. For purposes of such subrogation, no
payments or distributions to the holders of the Senior Debt of a Subsidiary Guarantor of any cash,
property or securities to which the Holders of the Securities or the Trustee would be entitled
except for the provisions of this Article, and no payments over pursuant to the provisions of this
Article to the holders of Senior Debt of a Subsidiary Guarantor by Holders of the Securities or the
Trustee, shall, as among a Subsidiary Guarantor, its creditors other than holders of Senior Debt of
such Subsidiary Guarantor and the Holders of the Securities, be deemed to be a payment or
distribution by such Subsidiary Guarantor to or on account of the Senior Debt of such Subsidiary
Guarantor.

SECTION 1407. Provisions Solely to Define Relative Rights.

     The provisions of this Article are and are intended solely for the purpose of defining the
relative rights of the Holders on the one hand and the holders of Senior Debt of a Subsidiary
Guarantor on the other hand. Nothing contained in this Article or elsewhere in this Indenture or
in the Subsidiary Guarantees is intended to or shall (a) impair, as among a Subsidiary Guarantor,
its creditors other than holders of Senior Debt of such Subsidiary Guarantor and the Holders of the
Securities, the obligation of such Subsidiary Guarantor, which is absolute and unconditional (and
which, subject to the rights under this Article of the holders of Senior Debt of such Subsidiary
Guarantor, is intended to rank equally with all other general obligations of such Subsidiary
Guarantor), to guarantee payment to the Holders of the Securities of the principal of

74

 

(and premium, if any) and interest on the Securities as and when the same shall become due and
payable in accordance with their terms; or (b) affect the relative rights against a Subsidiary
Guarantor of the Holders of the Securities and creditors of such Subsidiary Guarantor other than
the holders of Senior Debt of such Subsidiary Guarantor; or (c) 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 of the holders of Senior
Debt of a Subsidiary Guarantor to receive cash, property and securities otherwise payable or
deliverable to the Trustee or such Holder.

SECTION 1408. Trustee to Effectuate Subordination.

     Each Holder of a Security by his acceptance thereof authorizes and directs the Trustee on his
behalf to take such action as may be necessary or appropriate to effectuate the subordination
provided in this Article and appoints the Trustee his attorney-in-fact for any and all such
purposes.

SECTION 1409. No Waiver of Subordination Provisions.

     No right of any present or future holder of any Senior Debt of a Subsidiary Guarantor to
enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by
any act or failure to act on the part of such Subsidiary Guarantor or by any act or failure to act,
in good faith, by any such holder, or by any noncompliance by such Subsidiary Guarantor with the
terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such
holder may have or be otherwise charged with.

     Without in any way limiting the generality of the foregoing paragraph, the holders of Senior
Debt of a Subsidiary Guarantor may, at any time and from time to time, without the consent of or
notice to the Trustee or the Holders of the Securities, without incurring responsibility to the
Holders of the Securities and without impairing or releasing the subordination provided in this
Article or the obligations hereunder of the Holders of the Securities to the holders of Senior Debt
of such Subsidiary Guarantor, do any one or more of the following: (i) change the manner, place or
terms of payment or extend the time of payment of, or renew or alter, Senior Debt of such
Subsidiary Guarantor, or otherwise amend or supplement in any manner Senior Debt of such Subsidiary
Guarantor or any instrument evidencing the same or any agreement under which Senior Debt of such
Subsidiary Guarantor is outstanding; (ii) sell, exchange, release or otherwise deal with any
property pledged, mortgaged or otherwise securing Senior Debt of such Subsidiary Guarantor; (iii)
release any Person liable in any manner for the collection of Senior Debt of such Subsidiary
Guarantor; and (iv) exercise or refrain from exercising any rights against such Subsidiary
Guarantor and any other Person.

SECTION 1410. Notice to Trustee.

     Each Subsidiary Guarantor shall give prompt written notice to the Trustee of any fact known to
such Subsidiary Guarantor which would prohibit the making of any payment to or by the Trustee in
respect of its Subsidiary Guarantee. Notwithstanding the provisions of this Article or any other
provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of
any facts which would prohibit the making of any payment to or by the Trustee in

75

 

respect of the Subsidiary Guarantees, unless and until the Trustee shall have received written
notice thereof from a Subsidiary Guarantor or a holder of Senior Debt of such Subsidiary Guarantor
or from any trustee therefor; and, prior to the receipt of any such written notice, the Trustee,
subject to the provisions of Section 601, shall be entitled in all respects to assume that no such
facts exist; provided, however, that if the Trustee shall not have received the notice provided for
in this Section at least three Business Days prior to the date upon which by the terms hereof any
money may become payable for any purpose (including, without limitation, the payment of the
principal of (and premium, if any) or interest on any Security), then, anything herein contained to
the contrary notwithstanding, the Trustee shall have full power and authority to receive such money
and to apply the same to the purpose for which such money was received and shall not be affected by
any notice to the contrary which may be received by it within three Business Days prior to such
date.

     Subject to the provisions of Section 601, 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 Debt
of a Subsidiary Guarantor (or a trustee therefor) to establish that such notice has been given by a
holder of Senior Debt of such Subsidiary Guarantor (or a trustee therefor). 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 Debt of a Subsidiary Guarantor to participate in any payment or
distribution pursuant to this Article, the Trustee may request such Person to furnish evidence to
the reasonable satisfaction of the Trustee as to the amount of Senior Debt of such Subsidiary
Guarantor 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, 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 1411. Reliance on Judicial Order or Certificate of Liquidating Agent.

     Upon any payment or distribution of assets of a Subsidiary Guarantor referred to in this
Article, the Trustee, subject to the provisions of Section 601, and the Holders of the Securities
shall be entitled to rely upon any order or decree entered by any court of competent jurisdiction
in which such Guarantor Proceeding is pending, or a certificate of the trustee in bankruptcy,
receiver, liquidating trustee, custodian, 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 the Senior Debt of such Subsidiary Guarantor and other indebtedness of
such Subsidiary Guarantor, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article.

SECTION 1412. Trustee Not Fiduciary for Holders of Senior Debt of such Subsidiary Guarantor.

     The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt of a
Subsidiary Guarantor and shall not be liable to any such holders if it shall in good faith
mistakenly pay over or distribute to Holders of Securities or to the Company, a Subsidiary
Guarantor, or to any other Person cash, property or securities to which any holders of Senior Debt
of such Subsidiary Guarantor shall be entitled by virtue of this Article or otherwise.

76

 

SECTION 1413. Rights of Trustee as Holder of Senior Debt of such Subsidiary Guarantor; Preservation
of Trustee’s Rights.

     The Trustee in its individual capacity shall be entitled to all the rights set forth in this
Article with respect to any Senior Debt of a Subsidiary Guarantor which may at any time be held by
it, to the same extent as any other holder of Senior Debt of such Subsidiary Guarantor, and nothing
in this Indenture shall deprive the Trustee of any of its rights as such holder.

     Nothing in this Article shall apply to claims of, or payments to, the Trustee under or
pursuant to Section 607.

SECTION 1414. Article Applicable to Paying Agents.

     In case at any time any Paying Agent other than the Trustee shall have been appointed by the
Company and be then acting hereunder, the term “Trustee” as used in this Article shall in such case
(unless the context otherwise requires) be construed as extending to and including such Paying
Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named
in this Article in addition to or in place of the Trustee; provided, however, that Section 1413
shall not apply to the Company, any Subsidiary Guarantor or any Affiliate of the Company if it or
such Subsidiary Guarantor or Affiliate acts as Paying Agent.

SECTION 1415. Defeasance of this Article Fourteen.

     The subordination of the Subsidiary Guarantees provided by this Article Fourteen is expressly
made subject to the provisions for Defeasance or Covenant Defeasance of a series of Securities in
Article Fifteen hereof and, anything herein to the contrary notwithstanding, upon the effectiveness
of any such Defeasance or Covenant Defeasance with respect to a series of Securities, the
Subsidiary Guarantees of the Securities of such series shall thereupon cease to be subordinated
pursuant to this Article Fourteen.

ARTICLE FIFTEEN

DEFEASANCE AND COVENANT DEFEASANCE

SECTION 1501. Company’s Option to Effect Defeasance or Covenant Defeasance.

     The Company may elect, at its option at any time, to have Section 1502 or Section 1503 applied
to any Securities or any series of Securities, as the case may be, designated pursuant to Section
301 as being defeasible pursuant to such Section 1502 or 1503, in accordance with any applicable
requirements provided pursuant to Section 301 and upon compliance with the conditions set forth
below in this Article. Any such election shall be evidenced in or pursuant to a Board Resolution
or in another manner specified as contemplated by Section 301 for such Securities.

77

 

SECTION 1502. Defeasance and Discharge.

     Upon the Company’s exercise of its option (if any) to have this Section applied to any
Securities or any series of Securities, as the case may be, the Company shall be deemed to have
been discharged from its obligations, and each Subsidiary Guarantor shall be deemed to have been
discharged from its obligations with respect to its Subsidiary Guarantees of such Securities, and
the provisions of Articles Twelve and Fourteen shall cease to be effective, with respect to such
Securities and Subsidiary Guarantees as provided in this Section on and after the date the
conditions set forth in Section 1504 are satisfied (herein called “Defeasance”). For this purpose,
such Defeasance means that the Company shall be deemed to have paid and discharged the entire
indebtedness represented by such Securities and to have satisfied all its other obligations under
such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at
the expense of the Company, shall execute proper instruments acknowledging the same), subject to
the following which shall survive until otherwise terminated or discharged hereunder: (1) the
rights of Holders of such Securities to receive, solely from the trust fund described in Section
1504 and as more fully set forth in such Section, payments in respect of the principal of and any
premium and interest on such Securities when payments are due, or, if applicable, to convert such
Securities in accordance with their terms, (2) the Company’s and each Subsidiary Guarantor’s
obligations with respect to such Securities under Sections 304, 305, 306, 1002 and 1003, and, if
applicable, their obligations with respect to the conversion of such Securities, (3) the rights,
powers, trusts, duties and immunities of the Trustee hereunder and (4) this Article. Subject to
compliance with this Article, the Company may exercise its option (if any) to have this Section
applied to any Securities notwithstanding the prior exercise of its option (if any) to have Section
1503 applied to such Securities.

SECTION 1503. Covenant Defeasance.

     Upon the Company’s exercise of its option (if any) to have this Section applied to any
Securities or any series of Securities, as the case may be, (1) the Company shall be released from
its obligations under Section 801(3), Sections 1006 through 1008, inclusive, and any covenants
provided pursuant to Section 301(20), 901(2) or 901(7) for the benefit of the Holders of such
Securities, and (2) the occurrence of any event specified in Sections 501(5) (with respect to any
of Section 801(3), Sections 1006 through 1008, inclusive, and any such covenants provided pursuant
to Section 301(20), 901(2) or 901(7)), 501(6), 501(7), but only insofar as Sections 501(6) and
501(7) relate to Subsidiary Guarantors, 501(8) and 501(9) shall be deemed not to be or result in an
Event of Default and (3) the provisions of Articles Twelve, Thirteen and Fourteen shall cease to be
effective, in each case with respect to such Securities and Subsidiary Guarantees as provided in
this Section on and after the date the conditions set forth in Section 1504 are satisfied (herein
called “Covenant Defeasance”). For this purpose, such Covenant Defeasance means that, with respect
to such Securities, the Company and the Subsidiary Guarantors, as applicable, may omit to comply
with and shall have no liability in respect of any term, condition or limitation set forth in any
such specified Section (to the extent so specified in the case of Section 501(5)) or Article
Twelve, Thirteen or Article Fourteen, whether directly or indirectly by reason of any reference
elsewhere herein to any such Section or Article or by reason of any reference in any such Section
or Article to any other provision herein or in any other document, but the remainder of this
Indenture and such Securities shall be unaffected thereby.

78

 

SECTION 1504. Conditions to Defeasance or Covenant Defeasance.

     The following shall be the conditions to the application of Section 1502 or Section 1503 to
any Securities or any series of Securities, as the case may be:

     (1) The Company shall irrevocably have deposited or caused to be deposited with the
Trustee (or another trustee which satisfies the requirements contemplated by Section 609 and
agrees to comply with the provisions of this Article applicable to it) as trust funds in
trust for the purpose of making the following payments, specifically pledged as security
for, and dedicated solely to, the benefits of the Holders of such Securities, (A) money in
an amount, or (B) U.S. Government Obligations which through the scheduled payment of
principal and interest in respect thereof in accordance with their terms will provide, not
later than one day before the due date of any payment, money in an amount, or (C) a
combination thereof, in each case sufficient, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof delivered to
the Trustee, to pay and discharge, and which shall be applied by the Trustee (or any such
other qualifying trustee) to pay and discharge, the principal of and any premium and
interest on such Securities on the respective Stated Maturities, in accordance with the
terms of this Indenture and such Securities. As used herein, “U.S. Government Obligation”
means (x) any security which is (i) a direct obligation of the United States of America for
the payment of which the full faith and credit of the United States of America is pledged or
(ii) an obligation of a Person controlled or supervised by and acting as an agency or
instrumentality of the United States of America the payment of which is unconditionally
guaranteed as a full faith and credit obligation by the United States of America, which, in
either case (i) or (ii), is not callable or redeemable at the option of the issuer thereof,
and (y) any depositary receipt issued by a bank (as defined in Section 3(a)(2) of the
Securities Act) as custodian with respect to any U.S. Government Obligation which is
specified in clause (x) above and held by such bank for the account of the holder of such
depositary receipt, or with respect to any specific payment of principal of or interest on
any U.S. Government Obligation which is so specified and held, provided that (except as
required by law) such custodian is not authorized to make any deduction from the amount
payable to the holder of such depositary receipt from any amount received by the custodian
in respect of the U.S. Government Obligation or the specific payment of principal or
interest evidenced by such depositary receipt.

     (2) In the event of an election to have Section 1502 apply to any Securities or any
series of Securities, as the case may be, the Company shall have delivered to the Trustee an
Opinion of Counsel stating that (A) the Company has received from, or there has been
published by, the Internal Revenue Service a ruling or (B) since the date of this
instrument, there has been a change in the applicable Federal income tax law, in either case
(A) or (B) to the effect that, and based thereon such opinion shall confirm that, the
Holders of such Securities will not recognize gain or loss for Federal income tax purposes
as a result of the deposit, Defeasance and discharge to be effected with respect to such
Securities and will be subject to Federal income tax on the same amount, in the same manner
and at the same times as would be the case if such deposit, Defeasance and discharge were
not to occur.

79

 

     (3) In the event of an election to have Section 1503 apply to any Securities or any
series of Securities, as the case may be, the Company shall have delivered to the Trustee an
Opinion of Counsel to the effect that the Holders of such Securities will not recognize gain
or loss for Federal income tax purposes as a result of the deposit and Covenant Defeasance
to be effected with respect to such Securities and will be subject to Federal income tax on
the same amount, in the same manner and at the same times as would be the case if such
deposit and Covenant Defeasance were not to occur.

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

     (5) No event which is, or after notice or lapse of time or both would become, an Event
of Default with respect to such Securities or any other Securities shall have occurred and
be continuing at the time of such deposit or, with regard to any such event specified in
Sections 501(6) and (7), at any time on or prior to the 121st day after the date of such
deposit (it being understood that this condition shall not be deemed satisfied until after
such 121st day).

     (6) Such Defeasance or Covenant Defeasance shall not cause the Trustee to have a
conflicting interest within the meaning of the Trust Indenture Act (assuming all Securities
are in default within the meaning of such Act).

     (7) Such Defeasance or Covenant Defeasance shall not result in a breach or violation
of, or constitute a default under, any agreement or instrument (other than this Indenture)
to which the Company or any Subsidiary is a party or by which it is bound.

     (8) At the time of such deposit, (A) no default in the payment of any principal of or
premium or interest on any Senior Debt of the Company or any Subsidiary Guarantor shall have
occurred and be continuing, (B) no event of default with respect to any Senior Debt of the
Company or any Subsidiary Guarantor shall have resulted in such Senior Debt becoming, and
continuing to be, due and payable prior to the date on which it would otherwise have become
due and payable (unless payment of such Senior Debt has been made or duly provided for), and
(C) no other event of default with respect to any Senior Debt of the Company or any
Subsidiary Guarantor shall have occurred and be continuing permitting (after notice or lapse
of time or both) the holders of such Senior Debt (or a trustee on behalf of such holders) to
declare such Senior Debt due and payable prior to the date on which it would otherwise have
become due and payable.

SECTION 1505. Deposited Money and U.S. Government Obligations to Be Held in Trust; Miscellaneous
Provisions.

     Subject to the provisions of the last paragraph of Section 1003, all money and U.S. Government
Obligations (including the proceeds thereof) deposited with the Trustee or other qualifying trustee
(solely for purposes of this Section and Section 1506, the Trustee and any such other trustee are
referred to collectively as the “Trustee”) pursuant to Section 1504 in respect of any Securities
shall be held in trust and applied by the Trustee, in accordance with the provisions of such
Securities and this Indenture, to the payment, either directly or through any such Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders
of such Securities, of all sums due and to become due thereon in respect of principal and any
premium and interest, but money so held in trust need not be segregated from other funds except to
the extent required by law. Money and U.S. Government Obligations so held in trust shall not be
subject to the provisions of Article Twelve or Article Fourteen.

     The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed
on or assessed against the U.S. Government Obligations deposited pursuant to Section 1504 or the
principal and interest received in respect thereof other than any such tax, fee or other charge
which by law is for the account of the Holders of Outstanding Securities.

     Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to
the Company from time to time upon Company Request any money or U.S. Government Obligations held by
it as provided in Section 1504 with respect to any Securities which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then be required to be
deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to such
Securities.

SECTION 1506. Reinstatement.

     If the Trustee or the Paying Agent is unable to apply any money in accordance with this
Article with respect to any Securities by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such application, then the
obligations under this Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 1502 or 1503 shall be revived and reinstated as though no deposit had
occurred pursuant to this Article with respect to such Securities, until such time as the Trustee
or Paying Agent is permitted to apply all money held in trust pursuant to Section 1505 with respect
to such Securities in accordance with this Article; provided, however, that if the Company makes
any payment of principal of or any premium or interest on any such Security following such
reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the
Holders of such Securities to receive such payment from the money so held in trust.

ARTICLE SIXTEEN

SINKING FUNDS

SECTION 1601. Applicability of Article.

     The provisions of this Article shall be applicable to any sinking fund for the retirement of
Securities of any series except as otherwise specified as contemplated by Section 301 for such
Securities.

     The minimum amount of any sinking fund payment provided for by the terms of any Securities 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 such Securities is herein referred to as an “optional sinking
fund payment”. If provided for by the terms of any Securities, the cash amount of any sinking fund
payment may be subject to reduction as provided in Section 1602. Each sinking fund payment shall
be applied to the redemption of Securities as provided for by the terms of such Securities.

SECTION 1602. Satisfaction of Sinking Fund Payments with Securities.

     The Company (1) may deliver Outstanding Securities of a series (other than any previously
called for redemption) and (2) may apply as a credit Securities of a series which have been (x)
converted or (y) redeemed either at the election of the Company pursuant to the terms of such
Securities or through the application of permitted optional sinking fund payments pursuant to the
terms of such Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to any Securities of such series required to be made pursuant to the terms of
such Securities as and to the extent provided for by the terms of such Securities; provided,
however, that the Securities to be so credited have not been previously so credited. The
Securities to be so credited shall be received and credited for such purpose by the Trustee at the
Redemption Price, as specified in the Securities so to be redeemed, for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall be reduced
accordingly.

SECTION 1603. Redemption of Securities for Sinking Fund.

     Not less than 35 days prior to each sinking fund payment date for any Securities, the Company
will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing
sinking fund payment for such Securities pursuant to the terms of such Securities, the portion
thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which
is to be satisfied by delivering and crediting Securities pursuant to Section 1602 and will also
deliver to the Trustee any Securities to be so delivered. Not less than 32 days prior to each such
sinking fund payment date, the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 1103 and cause notice of the redemption
thereof to be given in the name of and at the expense of the Company in the manner provided in
Section 1104. Such notice having been duly given, the redemption of such Securities shall be made
upon the terms and in the manner stated in Sections 1106 and 1107.
