     Section 104. Acts of Holders; Record Dates.

provided or permitted by this Indenture to be given, made or taken by Holders may be embodied in
and evidenced by one or more instruments of substantially similar tenor signed by such Holders in
person or by an agent duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments are delivered to
the Trustee and, where it is hereby expressly required, to the Company. The Trustee shall promptly
deliver to the Company copies of all such instrument or instruments and records delivered to the
Trustee. Such instrument or instruments (and the action embodied therein and evidenced thereby) are
herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments.
Proof of execution of any such instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Indenture and (subject to Section 601) conclusive in favor of
the Trustee and the Company, 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 or her the execution thereof. Where such
execution is by a signer acting in a capacity other than his or her individual capacity, such
certificate or affidavit shall also constitute sufficient proof of his or her authority. The fact
and date of the execution of any such instrument or writing, or the authority of the Person
executing the same, may also be proved in any other manner which the Trustee deems sufficient.

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

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

     The Company may, in the circumstances permitted by the Trust Indenture Act, 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, vote, 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

9

 

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
further that no such action shall be effective hereunder unless taken on or prior
to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date. Nothing in this paragraph shall be construed to
prevent the Company 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 canceled 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
canceled 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 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 shall be sufficient for every purpose
hereunder if made, given, furnished or filed in writing (or by facsimile transmission
((646)-452-2000); provided that oral confirmation of receipt shall have been
received) to or with the Trustee at its Corporate Trust Office, or

     (2) the Company by the Trustee or by any Holder shall be sufficient for every purpose
hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class
postage prepaid, to the Company addressed to it at the address of the Company’s 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, Attention: Chief Financial
Officer, with a copy to the Secretary; provided that such notice shall not
be deemed to be given until received by the Company.

     Section 106. Notice to Holders; Waiver. 

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

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

     Section 107. 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 the Trust Indenture 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.

11

 

     Section 109. Successors and Assigns. 

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

     Section 110. Separability Clause. 

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

     Section 111. Benefits of Indenture. 

     Nothing in this Indenture or in the Securities, 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; Waiver of Jury Trial

     THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES THEREOF. EACH OF THE

LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS
INDENTURE, THE SECURITIES OR THE TRANSACTION CONTEMPLATED HEREBY.

     Section 113. Legal Holidays. 

     In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any
Security or the last date on which a Holder has the right to convert a Security at a particular
conversion price 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) or, if applicable to a particular series of Securities,
conversion need not be made at such Place of Payment on such date, but may be made on the next
succeeding Business Day at such Place of Payment with the same force and effect as if made on the
Interest Payment Date or Redemption Date, at the Stated Maturity or on such last day for
conversion, as the case may be.

     Section 114. Indenture and Securities Solely Corporate Obligations. 

     None of the Company’s or any Guarantor’s past, present or future directors, officers,
employees or shareholders, as such, shall have any liability for any of the Company’s or any
Guarantor’s obligations under this Indenture or the Securities or for any claim based on, or in
respect or by reason of, such obligations or their creation. By accepting a Security, each holder
waives and releases all such liability. This waiver and release is part of the consideration for
the issuance of the Securities.

     Section 115. Indenture May be Executed in Counterparts. 

     This Indenture 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

of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of
God, and interruptions, loss or malfunctions of utilities, communications or computer (software and
hardware) services; it being understood that the Trustee shall use reasonable efforts which are
consistent with accepted practices in the banking industry to resume performance as soon as
practicable under the circumstances.

     Section 118. U.S.A. Patriot Act

     The parties hereto acknowledge that in accordance with Section 326 of the U.S.A. Patriot Act,

hereinafter referred to), for value received, hereby promises to pay to                     , or
registered assigns, the principal sum of                      Dollars on                      [if the

trust office of the Trustee], in such coin or currency of the United States of America as at the
time of payment is legal tender for payment of public and private debts [if applicable, insert —;
provided, however, that at the 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
hereof, which further provisions shall for all purposes have the same effect as if set forth at
this place.

     Unless the certificate of authentication hereon has been executed by the Trustee referred to
on the reverse hereof by manual signature, this Security shall not be entitled to any benefit under
the Indenture or be valid or obligatory for any purpose.

     IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed.

                    , in each year beginning with the year                      and ending with the year                      of

     [If applicable, insert — The Indenture contains provisions for defeasance at any time of [the
entire indebtedness of this Security] [or] [certain restrictive covenants and Events of Default
with respect to this Security] [, in each case] upon compliance with certain conditions set forth
in the Indenture.]

     [If the Security is convertible into Common Stock of the Company, insert — Subject to the
provisions of the Indenture, the Holder of this Security is entitled, at its option, at any time on
or prior to Maturity (except that, in case this Security or any portion hereof shall be called for
redemption, such right shall terminate with respect to this Security or portion hereof, as the case
may be, so called for redemption at the close of business on the first Business Day next preceding
the date fixed for redemption as provided in the Indenture unless the Company defaults in making
the payment due upon redemption), to convert the principal amount of this Security (or any portion
hereof which is $1,000 or an integral multiple thereof), into fully paid and non-assessable shares
(calculated as to each conversion to the nearest 1/100th of a share) of the Common Stock of the
Company, as said shares shall be constituted at the date of conversion, at the conversion price of
$                     principal amount of Securities for each share of Common Stock, or at the adjusted
conversion price in effect at the date of conversion determined as provided in the Indenture, upon
surrender of this Security, together with the conversion notice hereon duly executed, to the
Company at the designated office or agency of the Company in                     , accompanied (if so
required by the Company) by instruments of transfer, in form satisfactory to the Company and to the
Trustee, duly executed by the Holder or by its duly authorized attorney in writing. Such surrender
shall, if made during any period beginning at the close of business on a Regular Record Date and
ending at the opening of business on the Interest Payment Date next following such Regular Record
Date (unless this Security or the portion being converted shall have been called for redemption on
a Redemption Date during the period beginning at the close of business on a Regular Record Date and
ending at the opening of business on the first Business Day after the next succeeding Interest
Payment Date, or if such Interest Payment Date is not a Business Day, the second such Business
Day), also be accompanied by payment in funds acceptable to the Company of an amount equal to the
interest payable on such Interest Payment Date on the principal amount of this Security then being
converted. Subject to the aforesaid requirement for payment and, in the case of a conversion after
the Regular Record Date next preceding any Interest Payment Date and on or before such Interest
Payment Date, to the right of the Holder of this Security (or any Predecessor Security) of record
at such Regular Record Date to receive an installment of interest (with certain exceptions provided
in the Indenture), no adjustment is to be made on conversion for interest accrued hereon or for
dividends on shares of Common Stock issued on conversion. The Company is not required to issue
fractional shares upon any such conversion, but shall make adjustment therefor in cash on the basis
of the current market value of such fractional interest as provided in the Indenture. The
conversion price is subject to adjustment as provided in the Indenture. In addition, the Indenture
provides that in case of certain consolidations or mergers to which the Company is a party or the
sale of substantially all of the assets of the Company, the Indenture shall be amended,

17

 

without the consent of any Holders of Securities, so that this Security, if then outstanding,
will be convertible thereafter, during the period this Security shall be convertible as specified
above, only into the kind and amount of securities, cash and other property receivable upon the
consolidation, merger or sale by a holder of the number of shares of Common Stock into which this
Security might have been converted immediately prior to such consolidation, merger or sale
(assuming such holder of Common Stock failed to exercise any rights of election and received per
share the kind and amount received per share by a plurality of non-electing shares). In the event
of conversion of this Security in part only, a new Security or Securities for the unconverted
portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof.]

     [If the Security is convertible into other securities of the Company, provides for adjustments
to the conversion rate or provides for other means to settle conversion, specify the conversion
features.]

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

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

     The Indenture permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Company and the rights of the Holders of the
Securities of each series to be affected under the Indenture at any time by the Company and the
Trustee with the consent of the Holders of at least 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
indemnity reasonably satisfactory to it, 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.

18

 

     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 its 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.

     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.

contrary.

without regard to conflict of laws principles thereof.

shall be deemed to be Outstanding as of any date prior to the Stated Maturity (or, in any
such case, the manner in which such amount deemed to be the principal amount shall be
determined);

     (17) if applicable, that the Securities of the series, in whole or any specified part,
shall be defeasible pursuant to Section 1302 or Section 1303 or both such Sections and, if
other than by a Board

24

 

Resolution, the manner in which any election by the Company to defease such Securities
shall be evidenced and any changes or additions to the provisions provided in Article
Thirteen of this Indenture and related definitions and provisions dealing with defeasance,
including the addition of additional covenants that may be subject to the Company’s Covenant
Defeasance option;

     (18) if applicable, the terms of any right to convert Securities of the series into, or
exchange securities for, shares of Common Stock of the Company or other securities or
property or cash in lieu of such Common Stock or other securities or property, or any
combination thereof, and any corresponding changes to the provisions of this Indenture as
then in effect;

     (19) if applicable, that any Securities of the series shall be issuable in whole or in
part in the form of one or more Global Securities and, in such case, the respective
Depositaries for such Global Securities, the form of any legend or legends which shall be
borne by any such Global Security in addition to or in lieu of that set forth in Section 204
and any circumstances in addition to or in lieu of those set forth in Clause (2) of the last
paragraph of Section 305 in which any such Global Security may be exchanged in whole or in
part for Securities registered, and any transfer of such Global Security in whole or in part
may be registered, in the name or names of Persons other than the Depositary for such Global
Security or a nominee thereof;

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

Securities to declare the principal amount thereof due and payable pursuant to Section 502;

     (21) any Authenticating Agents, Paying Agents or Security Registrars;

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

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

     All Securities of any one series shall be substantially identical except as to denomination
and except as may otherwise be provided in or pursuant to the Board Resolution referred to above
and (subject to Section 303) set forth, or determined in the manner provided, in the Officers’
Certificate referred to above or in any such indenture supplemental hereto. All Securities of any
one series need not be issued at the same time and, unless otherwise provided, a series may be
reopened for issuances of additional Securities of such series.

25

 

     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.

     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 minimum denominations of $2,000 and any integral multiple of
$1,000 in excess 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 principal financial officer, its Chief Executive Officer, its President or one of
its Vice Presidents, its Treasurer or its Assistant Treasurer, 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.

     The Guarantee endorsed on any Securities shall be executed on behalf of the Guarantor by its
Chairman of the Board of Directors, its principal financial officer, its Chief Executive Officer,
its President or one of its Vice Presidents, its Treasurer or its Assistant Treasurer, attested by
its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the
Guarantee may be manual or facsimile.

     Securities or the Guarantee bearing the manual or facsimile signatures of individuals who were
at any time the proper officers of the Company or the Guarantors, as applicable, shall bind the
Company or the Guarantors, as applicable, 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 Guarantees executed as provided in Section 1502 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 (which may provide that Securities
that are the subject thereof will be authenticated and delivered by the Trustee from time to time
upon the telephonic or written order of Persons designated in said Company Order and that such
Persons are authorized to determine such terms and conditions of said Securities as are specified
in 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 receive,
and (subject to Section 601) shall be fully protected in conclusively relying upon, a copy of such
Board Resolution, the Officers’ Certificate setting forth the terms of the series and an Opinion of
Counsel, with such Opinion of Counsel stating,

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

     (3) that this Indenture and 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 Guarantees endorsed thereon will constitute valid and
legally binding obligations of the Guarantors, in each case 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; and

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

     However, 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 Guarantee endorsed thereon 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 in lieu of which they are
issued and with such appropriate insertions, omissions, substitutions and other variations as the
officers executing such Securities may determine, as evidenced by their execution of such
Securities.

27

 

     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. 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 or 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 initially is hereby
appointed “Security Registrar” for the purpose of registering Securities and transfers of
Securities as herein provided. The Company may change any Security Registrar without prior notice
to any Holder. The Company or any of its Subsidiaries may act as Security Registrar.

     Upon surrender for registration of transfer of any Security of a series at the office or
agency of the Company in a Place of Payment for that series, the Company shall execute, and the
Trustee shall authenticate and 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, and having endorsed thereon a Guarantee executed by the Guarantors.

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

     All Securities and the Guarantee endorsed thereon issued upon any registration of transfer or
exchange of Securities and the Guarantee endorsed thereon, shall be the valid obligations of the
Company and the Guarantors, respectively evidencing the same debt, and entitled to the same
benefits under this Indenture, as the Securities and the Guarantee endorsed thereon 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 its 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 Sections 304, 906 or 1107 not involving any transfer.

28

 

     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, (B) there shall have occurred and be continuing an Event of Default with respect to
such Global Security or (C) there shall exist such circumstances, if any, in addition to or
in lieu of the foregoing as have been specified for this purpose as contemplated by Section
301.

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

     (4) Every Security authenticated and 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 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, and
having endorsed thereon a Guarantee executed by the Guarantors, if applicable.

     If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction
of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be
required by them to save each of them and any agent of either of them harmless, then, in the
absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute 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

29

 

of like tenor and principal amount and bearing a number not contemporaneously outstanding, and
having endorsed thereon a Guarantee executed by the Guarantors, if applicable.

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

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

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

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

     Section 307. Payment of Interest; Interest Rights Preserved. 

     Except as otherwise provided in or 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; provided that on the maturity date for any series of Securities,
the Company will pay accrued and unpaid interest to the Person to whom the Company pays the
principal amount, instead of 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.

     In the case of Securities represented by a Global Security registered in the name of or held
by a Depository or its nominee, unless otherwise specified by Section 301, payment of principal,
premium, if any, and interest, if any, will be made to the Depository or its nominee, as the case
may be, as the registered owner or Holder of such Global Security. None of the Company, the
Guarantors, the Trustee and the Paying Agent, any Authenticating Agent or the Security Registrant
for such Securities will have any responsibility or liability for any aspect of the records
relating to or payments made on account of a beneficial ownership interest in a Global Security or
maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

     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

30

 

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 fewer than 10 days prior to the date of the proposed
payment and not fewer 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 fewer 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.

     Subject to the provisions of Section 1402, in the case of any Security (or any part thereof)
which is converted after any Regular Record Date and on or prior to the next succeeding Interest
Payment Date (other than any Security the principal of (or premium, if any, on) which shall become
due and payable, whether at Stated Maturity or by declaration of acceleration or otherwise prior to
such Interest Payment Date), interest whose Stated Maturity is on such Interest Payment Date shall
be payable on such Interest Payment Date notwithstanding such conversion and such interest (whether
or not punctually paid or duly provided for) shall be paid to the Person in whose name that
Security (or any one or more Predecessor Securities) is registered at the close of business on such
Regular Record Date. Except as otherwise expressly provided in the immediately preceding sentence
or in Section 1402, in the case of any Security (or any part thereof) which is converted, interest
whose Stated Maturity is after the date of conversion of such Security (or such part thereof) shall
not be payable.

     Section 308. Persons Deemed Owners. 

     Prior to due presentment of a Security for registration of transfer, the Company, the
Guarantors, the Trustee and any agent of the Company, the 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 none
of the Company, the Guarantors, the Trustee or any agent of the Company, the Guarantors or the
Trustee shall be affected by notice to the contrary.

     In the case of a Global Security, so long as the Depository for such Global Security, or its
nominee, is the registered owner of such Global Security, such Depository or such nominee, as the
case may be, will be considered

31

 

the sole owner or Holder of the Securities represented by such Global Security for all
purposes under this Indenture. Except as provided in Section 305, owners of beneficial interests in
a Global Security will not be entitled to have Securities that are represented by such Global
Security registered in their names, will not receive or be entitled to receive physical delivery of
such Securities in definitive form and will not be considered the owners or Holders thereof under
this Indenture.

     Notwithstanding the foregoing, with respect to any Global Security, nothing herein shall (a)
prevent the Company, the Guarantors, the Trustee, or any agent of the Company, the Guarantors or
the Trustee, from giving effect to any written certification, proxy or other authorization
furnished by a Depository or (b) impair, as between a Depository and holders of beneficial interest
in any Global Security, the operation of customary practices governing the exercise of the rights
of the Depository as Holder of such Global Security.

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

     Section 309. Cancellation.

     All Securities surrendered for payment, redemption, registration of transfer or exchange or
for credit against any sinking fund payment shall, if surrendered to any Person other than the
Trustee, be delivered to the Trustee and shall be promptly canceled 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 canceled by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities canceled as provided in this Section, except as expressly
permitted by this Indenture. All canceled Securities shall be disposed of by the Trustee in
accordance with its customary procedures.

     Section 310. Computation of Interest. 

     Except as otherwise specified in or 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
comprised of twelve 30-day months.

     Section 311. CUSIP Numbers. 

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

of a nationally recognized firm of independent certified public accountants expressed in a written
certification thereof delivered to the Trustee, to pay and discharge the entire indebtedness on

Trustee.

     Section 403. Repayment to the Company. 

     Upon termination of the trust pursuant to Section 401 hereof, the Trustee and Paying Agent
shall promptly pay to the Company any excess money or U.S. Government Obligations.

ARTICLE FIVE

REMEDIES

     Section 501. Events of Default. 

     “Event of Default,” wherever used herein with respect to Securities of any series, means any
one of the following events (whatever the reason for such Event of Default and whether it be
voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or
order of any court or any order, rule or regulation of any administrative or governmental body),
except to the extent such event is specifically deleted or modified as contemplated by Section 301
for the Securities of that series:

becomes due and payable, and continuance of such default for a period of 30 days; or

     (2) default in the payment of the principal of or any premium on any Security of that

breach for a period of 90 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 Holders of at least
25% in principal amount of the Outstanding Securities of that series a written notice

of its Guarantors in furtherance of any such action; or

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

     Section 502. Acceleration of Maturity; Rescission and Annulment. 

     If an Event of Default, other than an Event of Default specified in Sections 501(5) or 501(6)
solely with respect to the Company (but including an Event of Default referred to in those Sections
solely with respect to any Significant Subsidiary of the Company), with respect to Securities of
any series at the time Outstanding occurs and is continuing, then either the Trustee, by notice to
the Company, or the Holders of not less than 25% in principal amount of the Outstanding Securities
of that series, by notice to the Trustee and the Company, may declare the principal amount of, and
accrued and unpaid interest on, 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

35

 

specified by the terms thereof) to be due and payable immediately. In the case of an Event of
Default specified in Section 501(5) or 501(6) solely with respect to the Company (and not solely
with respect to any Significant Subsidiary of the Company) and with respect to Securities of any
series at the time Outstanding occurs, the principal amount of (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), and accrued and unpaid interest on, all the
Securities of that series shall automatically, and without any action by the Trustee or any Holder,
become immediately due and payable.

     Notwithstanding the foregoing, for the first 180 days following any violation of any
obligations the Company may be deemed to have pursuant to Section 314(a)(1) of the Trust Indenture
Act or the Company’s other reporting and information delivery obligations with respect to filings
with the Commission as provided in Section 704, at the Company’s option, the sole remedy of the
Holders of the Securities shall be the accrual of additional interest on the Securities while such
Default exists at a rate of 0.25% per annum, payable semi-annually. In no event shall such
additional interest accrue at a rate per annum in excess of 0.25% per annum, regardless of the
number of events or circumstances giving rise to the requirement to pay such additional interest.

     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 rescission would not conflict with any order or decree;

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

     (3) the Company 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, to the
extent that payment is lawful;

     (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.

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

36

 

     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 the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own
name and as trustee of an express trust, may institute a judicial proceeding for the collection of
the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may
enforce the same against the Company or any Guarantor or any other obligor upon such Securities and
collect the moneys adjudged or decreed to be payable in the manner provided by law out of the
property of the Company, any Guarantor or any other obligor upon such Securities, wherever
situated.

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

     No provision of this Indenture shall be deemed to authorize the Trustee to authorize or
consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the

37

 

Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect
of the claim of any Holder in any such proceeding.

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

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

     Section 506. Application of Money Collected. 

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

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

     SECOND: In case the principal of the Securities of such series in respect of which moneys have
been collected shall not have become and be then due and payable, to the payment of interest, if
any, on the Securities of such series in default in the order of the maturity of the installments
of such interest, with interest (to the extent that such interest has been collected by such
Trustee and to the extent permitted by law) upon the overdue installments of interest at the rate
prescribed therefor in such Securities, such payments to be made ratably to the persons entitled
thereto, without discrimination or preference;

     THIRD: In case the principal or any premium of the Securities of such series in respect of
which moneys have been collected shall have become and shall be then due and payable, to the
payment of the whole amount then owing and unpaid upon all the Securities of such series for
principal, any premium and interest, if any, with interest upon the overdue principal, and (to the
extent that such interest has been collected by such Trustee and to the extent permitted by law)
upon overdue installments of interest at the rate prescribed therefor in the Securities of such
series; and in case such moneys shall be insufficient to pay in full the whole amount so due and
unpaid upon the Securities of such series, then to the payment of such principal, any premium and
interest, without preference or priority of principal over interest, or of interest over principal,
or of any installment of interest over any other installment of interest, or of any Security of
such series over any other Security of such series, ratably to the aggregate of such principal and
accrued and unpaid interest; and

     FOURTH: The balance, if any, to the Company or any other Person or Persons lawfully entitled
thereto.

38

 

     Section 507. Limitation on Suits. 

     No Holder of any Security of any series shall have any right to institute any proceeding under
this Indenture, or for the appointment of a receiver or trustee, or for any other remedy under this
Indenture, unless each of the following shall have occurred:

     (1) such Holder has previously given the Trustee written notice 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 make a written request to the Trustee to pursue the remedy and offer, and if
requested provide, to the Trustee indemnity reasonably satisfactory to the Trustee against
any loss, liability or expense incurred in connection with such pursuit; and

     (3) the Trustee fails to comply with such request within 60 days after the Trustee
receives the notice, request and offer of indemnity and does not receive, during those 60
days, from Holders of a majority in aggregate principal amount of Outstanding Securities of
such series, a direction inconsistent with such request.

     However, the above limitations do not apply to a suit by a Holder to enforce (a) the payment
of amounts due on that Holder’s Securities after the applicable due date or (b) the right to
convert that Holder’s Securities in accordance with this Indenture.

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

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

     Section 509. Restoration of Rights and Remedies. 

     If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy
under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has
been determined adversely to the Trustee or to such Holder, then and in every such case, subject to
any determination in such proceeding, the Company, any Guarantor, 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.

39

 

     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 (subject to the limitations contained in this
Indenture) 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 the Trustee shall not have determined that the action so directed would be unjustly
prejudicial to Holders of Securities of that series, or any other series, not taking part in
such direction; and

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

     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 of the Securities of such series waive any past
default hereunder with respect to such series and its consequences, except a default:

     (1) in the payment of the principal of or any premium or interest on any Security of
such series or the payment of any redemption price, purchase price or repurchase price with
respect to any Security of such series;

     (2) arising from the Company’s failure to convert any Security in accordance with this
Indenture; or

40

 

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

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

     Section 514. Undertaking for Costs. 

     All parties to this Indenture agree, and each Holder of any Security by his or her acceptance
thereof, shall be deemed to have agreed that any court may in its discretion require, in any suit
for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee
for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit and that such court may in its discretion
assess reasonable costs, including reasonable attorney’s fees and expenses, against any party
litigant in such suit, in the manner and to the extent provided in the Trust Indenture Act;
provided that neither this Section nor the Trust Indenture Act shall be deemed to
authorize any court to require such an undertaking or to make such an assessment in any suit
instituted by the Company or in any suit for the enforcement of the right to convert any Security
in accordance with Article Fourteen or in any suit instituted by the Trustee, to any suit
instituted by any Holder or group of Holders for the enforcement of the payment of the principal
of, or any premium or interest on, any Security on or after the due date for such payment.

     Section 515. Waiver of Stay or Extension Laws. 

     The Company 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
stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the
covenants or the performance of this Indenture; and the Company (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. No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure to act or its own
willful misconduct, subject to Section 603.

41

 

     Section 602. Notice of Defaults. 

     If a Default or Event of Default has occurred and the Trustee has received notice of the
Default or Event of Default in accordance with this Indenture, the Trustee must mail to each Holder
a notice of the Default or Event of Default within 90 days after the occurrence of the Event of
Default. However, the Trustee need not mail the notice if the Default or Event of Default (a) has
been cured or waived; or (b) is not in the payment of any amounts due with respect to any Security
or the failure to convert any Security in accordance with the Indenture and the Trustee in good
faith determines that withholding the notice is in the best interests of Holders. In addition, the
Trustee shall give the Holders of Securities of such series notice of such Default or Event of
Default actually known to it as and to the extent provided by the Trust Indenture Act.

     Section 603. Certain Rights of Trustee. 

     Subject to the provisions of Section 601:

     (1) in the absence of bad faith on the part of the Trustee, the Trustee may
conclusively rely and shall be protected in acting or refraining from acting upon any
resolution, certificate, statement, instrument, opinion, report, notice, request, 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 may 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, conclusively rely upon an Officers’ Certificate;

     (4) the Trustee may consult with counsel of its selection and the advice of such
counsel or any Opinion of Counsel shall be full and complete authorization and protection in
respect of any action taken, suffered or omitted 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, direction or demand of any of the Holders
pursuant to this Indenture, unless such Holders shall have offered to the Trustee security
or indemnity that is reasonably satisfactory to the Trustee against the
costs, expenses and liabilities which might be incurred by it in compliance with such
request, direction or demand;

     (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 further inquiry or
investigation into such facts or matters as it may see fit;

42

 

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

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

     (9) the Trustee shall not be deemed to have notice of any Default or Event of Default
unless a responsible officer of the Trustee has actual knowledge thereof or unless written
notice of any event which is in fact such a Default is received by the Trustee at the
Corporate Trust Office of the Trustee, and such notice references the Securities and this
Indenture;

     (10) the permissive rights of the Trustee to do the things enumerated in this Indenture
shall not be construed as a duty unless so specified herein. The Trustee shall not be liable
in connection with the performance of its duties hereunder, except for its own negligence or
willful misconduct;

     (11) whenever in the administration of the trusts imposed upon it by this Indenture the
Trustee shall deem it necessary or desirable that a matter be proved or established prior to
taking or suffering any action hereunder, such matter may be deemed to be conclusively
proved and established by an Officers’ Certificate, and such Officers’ Certificate shall be
full warrant to the Trustee for any action taken or suffered in good faith under the
provisions of the Indenture in reliance upon such Officers’ Certificate, but in its
discretion the Trustee may, in lieu thereof, accept other evidence of such matter or may
request such additional evidence as it may deem reasonable;

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

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

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

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

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

     The recitals contained herein and in the Securities, except the Trustee’s certificates of
authentication, shall be taken as the statements of the Company, and neither the Trustee nor any
Authenticating Agent assumes any

43

 

responsibility for their correctness. The Trustee makes no representations as to the validity,
sufficiency or priority of this Indenture or of the Securities, except that the Trustee represents
that it is duly authorized to execute and deliver this Indenture, authenticate the Securities and
perform its obligations hereunder, and that the statements made by it or to be made by it in a
Statement of Eligibility on Form T-1 supplied to the Company are true and accurate as of the date
thereof. 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 and Act as Trustee Under Other Indentures. 

     The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other
agent of the Company, 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 with the same
rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar
or such other agent.

     Subject to the limitations imposed by the Trust Indenture Act, nothing in this Indenture shall
prohibit the Trustee from becoming and acting as trustee under other indentures under which other
securities, or certificates of interest of participation in other securities, of the Company are
outstanding in the same manner as if it were not Trustee hereunder.

     Section 606. Money Held in Trust. 

     Subject to the provisions of the last paragraphs of Sections 1003 and 1305, all money received
by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes
for which they were received, but need not be segregated from other funds except to the extent
required by law. The Trustee shall be under no liability for interest on any money received by it
hereunder except as otherwise agreed in writing with the Company.

     Section 607. Compensation and Reimbursement. 

     The Company agrees:

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

     (2) except as otherwise expressly provided herein, to reimburse the Trustee upon its
request for all reasonable expenses, disbursements and advances 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 willful
misconduct; and

     (3) to indemnify the Trustee for, and to hold it harmless against, any and all loss,
liability, damage, claim (including taxes (other than taxes based on the income of the
Trustee)) or expense incurred without negligence or willful misconduct 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

44

 

any claim (whether asserted by the Company, a Guarantor, a Holder or any other Person)
or liability in connection with the exercise or performance of any of its powers or duties
hereunder.

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

     The Trustee shall have a lien prior to the Securities as to all property and funds held by it
hereunder for any amount owing it or any predecessor Trustee pursuant to this Section 607, except
with respect to funds held in trust for the benefit of the Holders of particular Securities.

     The provisions of this Section shall survive the termination of this Indenture.

     Section 608. Conflicting Interests.

     If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust
Indenture Act, the Trustee shall either eliminate such interest within 90 days 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 the 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 (or if the Trustee is a member of a bank holding company system, its bank holding
company has) a combined capital and surplus of at least $50,000,000 and shall be subject to
supervision or examination by a Federal or State authority. If any such Person 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 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

45

 

Trustee may petition, at the expense of the Company, 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 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 removal, the Trustee being removed may petition, at the expense of the
Company, any court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

     If at any time:

     (1) the Trustee shall fail to comply with Section 608 after written request therefor by
the Company or by any Holder who has been a bona fide Holder of a Security for at least six
months,

     (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 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, the retiring Trustee may petition, or 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

46

 

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

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

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

     Any corporation into which the Trustee may be merged or converted or with which it may be
consolidated, or any corporation resulting from any merger, conversion or consolidation to which
the Trustee shall be a party, or any corporation succeeding to all or substantially all the
corporate trust business of the Trustee, shall be the

47

 

successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and
eligible under this Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been authenticated, but not
delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to
such authenticating Trustee may adopt such authentication and deliver the Securities so
authenticated with the same effect as if such successor Trustee had itself authenticated such
Securities.

     Section 613. Preferential Collection of Claims Against the Company. 

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

     Section 614. Appointment of Authenticating Agent. 

     The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series
of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities
of such series issued upon original issue and upon exchange, registration of transfer or partial
redemption thereof or pursuant to Section 305, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee’s certificate of
authentication, such reference shall be deemed to include authentication and delivery on behalf of
the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business under the laws of the
United States of America, any State thereof or the District of Columbia, authorized under such laws
to act as Authenticating Agent, having (or if the Authenticating Agent is a member of a bank
holding company system, its bank holding company has) a combined capital and surplus of not less
than $50,000,000 and subject to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such Authenticating Agent shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so published. If at any
time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this
Section, such Authenticating Agent shall resign immediately in the manner and with the effect
specified in this Section.

     Any corporation into which an Authenticating Agent may be merged or converted or with which it
may be consolidated, or any corporation resulting from any merger, conversion or consolidation to
which such Authenticating Agent shall be a party, or any corporation succeeding to all or
substantially all the corporate agency or corporate trust business of an Authenticating Agent,
shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible
under this 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 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

48

 

predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No
successor Authenticating Agent shall be appointed unless eligible under the provisions of this
Section.

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

     If an appointment with respect to one or more series is made pursuant to this Section 614, 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.

as Security Registrar. The Trustee may destroy any list furnished to it as provided in Section 701
upon receipt of a new list so furnished.

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

50

 

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

     Section 703. Reports by Trustee. 

     The Trustee shall transmit to Holders of Securities, as their names and addresses appear in

Trustee with each stock exchange upon which any Securities are listed, with the Commission and with
the Company. The Company will promptly notify the Trustee in writing when any Securities are listed
on any stock exchange or of any delisting therefrom.

     Section 704. Reports by Company. 

     The Company shall file with the Trustee and the Commission, and transmit to Holders, 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;
provided further that any such information, documents or reports filed with the
Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval (or EDGAR) system
shall be deemed to be filed with the Trustee, provided further that the Trustee shall have no duty
to determine whether such filing has occurred.

     Delivery of such reports, information and documents to the Trustee is for informational
purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any
information contained therein or determinable from information contained therein, including the
Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to
rely exclusively on Officers’ Certificates).

     Section 906. Reference in Securities to Supplemental Indentures. 

     Securities of any series authenticated and delivered after the execution of any supplemental
indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in
form approved by the Trustee as to any matter provided for in such supplemental indenture. If the
Company shall so determine, new Securities of any series so modified as to conform, in the opinion
of the Trustee and the Company, to any such supplemental indenture may be prepared and executed by
the Company and authenticated and delivered by the Trustee in exchange for Outstanding Securities
of such series.

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.

     Section 1002. Maintenance of Office or Agency. 

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

56

 

office or agency or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office
of the Trustee, and the Company hereby appoints the Trustee as 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 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, on or prior to each due date of the principal of or any premium or interest on any Securities
of that series, deposit with a Paying Agent a sum sufficient to pay such principal or any premium
or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled
to such principal or any premium or interest, 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) hold all sums
held by it for the payment of the principal of (and premium, if any) or interest on Securities of
that series in trust for the benefit of the Persons entitled thereto until such sums shall be paid
to such Persons or otherwise disposed of as herein provided; (2) give the Trustee notice of any
default by the Company (or any other obligor upon the Securities of that series) in the making of
any payment of principal (and premium, if any) or interest on the Securities of that series; and
(3) at any time during the continuance of any such default, 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 (and premium, if any) or interest on any Security of any
series and remaining unclaimed for a period ending on the earlier of the date that is ten Business
Days prior to the date such money would escheat to the State or two years after such principal (and
premium, if any) 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

57

 

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.

     Section 1004. Statement by Officers as to Default. 

     The Company will promptly notify the Trustee in writing upon its becoming aware of the
occurrence of any Default or Event of Default. In addition, Company shall furnish to the Trustee,
within 120 days after the end of each fiscal year of the Company ending after the date of the
Indenture, an Officers’ Certificate stating whether the officers certifying therein have actual
knowledge of any Default or Event of Default by the Company in performing any of its obligations
under the Indenture or the Securities and describing any such Default or Event of Default.

     Section 1005. Existence. 

     Subject to Article Eight, the Company will do or cause to be done all things reasonably
necessary to preserve and keep in full force and effect its corporate existence.

     Section 1006. 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, all taxes, assessments and governmental charges levied or imposed upon the
Company or upon the income, profits or 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 or charge (i) whose amount, applicability or validity is being
contested in good faith by appropriate proceedings or (ii) if the failure to pay or discharge would
not have a material adverse effect on the assets, business, operations, properties or condition
(financial or otherwise) of the Company and its Subsidiaries, taken as a whole.

     Section 1007. Calculation of Original Issue Discount. 

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

ARTICLE 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.

58

 

     Section 1102. Election to Redeem; Notice to Trustee. 

     The election of the Company to redeem any Securities shall be evidenced by a Board Resolution.
In case of any redemption at the election of the Company of the Securities of any series (including
any such redemption affecting only a single Security), the Company shall, at least 40 days (or 45
days if fewer than all the Securities of any series are to be redeemed) prior to the Redemption
Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee of such Redemption Date, of the principal amount of Securities of such series to be
redeemed and, if applicable, of the tenor of the Securities to be redeemed. In the case of any
redemption of Securities prior to the expiration of any restriction on such redemption provided in
the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee
with an Officers’ Certificate evidencing compliance with such restriction.

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

     If fewer than all the Securities of any series are to be redeemed (unless all the Securities
of such series and of a specified tenor are to be redeemed or unless such redemption affects only a
single Security), the particular Securities to be redeemed shall be selected not more than 45 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not
previously called for redemption, by lot, or in the Trustee’s discretion, on a pro-rata basis or by
such other method as the Trustee may deem fair and appropriate, 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 fewer than
all the Securities of such series and of a specified tenor are to be redeemed (unless such
redemption affects only a single Security), the particular Securities to be redeemed shall be
selected not more than 45 days prior to the Redemption Date by the Trustee, from the Outstanding
Securities of such series and specified tenor not previously called for redemption in accordance
with the preceding sentence.

     If any Security selected for partial redemption is converted in part before termination of the
conversion right with respect to the portion of the Security so selected, the converted portion of
such Security shall be deemed (so far as may be), at the option of the Company, to be the portion
selected for redemption. Securities which have been converted during a selection of Securities to
be redeemed shall be treated by the Trustee as Outstanding for the purpose of such selection. 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 three 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.

59

 

     Section 1104. Notice of Redemption. 

     Notice of redemption shall be given by first-class mail, postage prepaid, mailed not fewer
than 30 nor more than 60 days prior to the Redemption Date, unless a shorter period is specified in
the Securities to be redeemed, to each Holder of Securities to be redeemed, at its address
appearing in the Security Register.

     Failure to give notice by mailing in the manner herein provided to the Holder of any
Registered Securities designated for redemption as a whole or in part, or any defect in the notice
of any such Holder, shall not affect the validity of the proceedings for the redemption of any
other Securities or portion thereof.

     Any notice that is mailed to the Holder of any Registered Securities in the manner herein
provided shall be conclusively presumed to have been duly given, whether or not such Holder
receives the notice.

     All notices of redemption shall identify the Securities to be redeemed (including CUSIP
number(s)) and shall state:

     (1) the Redemption Date;

     (2) the Redemption Price (including accrued interest, if any);

     (3) if fewer 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 fewer 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) if applicable, the conversion price, that the date on which the right to convert
the principal of the Securities or the portions thereof to be redeemed will terminate will
be the Business Day prior to the Redemption Date and the place or places where such
Securities may be surrendered for conversion;

     (7) in case any Securities are to be redeemed in part only, the notice which relates to
such Security shall state that on and after the Redemption Date, upon surrender of such
Security, the Holder of such Security will receive, without charge, a new Security or
Securities of authorized denominations for the principal amount thereof remaining
unredeemed; and

     (8) that the redemption is for a sinking fund, if such is the case.

60

 

     Notice of redemption of Securities to be redeemed at the election of the Company shall be
given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of
the Company and shall be irrevocable.

     Section 1105. Deposit of Redemption Price. 

     On or prior to 11:00 a.m., New York 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.

     If any Security called for redemption is converted, any money deposited with the Trustee or
with a Paying Agent or so segregated and held in trust for the redemption of such Security shall
(subject to the right of any Holder of such Security to receive interest as provided in the last
paragraph of Section 307) be paid to the Company on Company Request, or if then held by the
Company, shall be discharged from such trust.

     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 and unpaid 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 and unpaid interest to the Redemption Date;
provided, however, that, unless otherwise specified in or 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 its attorney duly authorized in writing), and the Company shall execute, and the
Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new
Security or Securities of the same series, having endorsed thereon the Guarantee executed by the
Guarantors 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. If a Security in global form is so surrendered, the Company shall
execute, and the Trustee shall authenticate and deliver to the U.S. Depositary or other Depositary
for such Security in global form as shall be specified in the Company Order with respect thereto to
the Trustee, without service charge, a new Security in global form in denomination equal to and in
exchange for the unredeemed portion of the principal of the Security in global form so surrendered.

ARTICLE TWELVE

SINKING FUNDS

     Section 1201. 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 1202. Each sinking fund payment shall be
applied to the redemption of Securities as provided for by the terms of such Securities.

     Section 1202. 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
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
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 1203. Redemption of Securities for Sinking Fund. 

     Not fewer than 60 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 1202 and will also
deliver to the Trustee any Securities to be so delivered. Not fewer than 30 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.

     Section 1301.  [Intentionally Omitted]. 

     [Intentionally omitted.]

     Section 1302. Defeasance and Discharge.

     The Company shall be deemed to have been discharged from its obligations with respect to any
Securities or any series of Securities, and each Guarantor shall be deemed to have been discharged
from its obligations with respect to its Guarantee of such Securities, as provided in this Section
on and after the date the conditions set forth in Section 1304, in the case of defeasance, are
satisfied (hereinafter 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 all the Securities of such series have in fact been paid in full: (1) the rights of Holders
of such Securities to receive, solely from the trust fund described in Section 1304 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, (2) the Company’s obligations with respect to
such Securities under Sections 304, 305, 306, 1002 and 1003, and, if applicable, Article Fourteen,
(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 1303 applied to such Securities.

     Section 1303. Covenant Defeasance. 

     On and after the date the conditions set forth in Section 1304 are satisfied, (1) the Company
shall be released from its obligations under Article Eight, Sections 704 and 1006, inclusive, and
(2) the occurrence of any event specified in Sections 501(4) (with respect to any of Article Eight,
Section 704 or Section 1006, inclusive, shall be deemed not to be or result in an Event of Default,
in each case with respect to Outstanding Securities of such series as provided in this Section
(hereinafter called “Covenant Defeasance”). For this purpose, such Covenant Defeasance means that,
with respect to such Securities, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such specified Article or Section (to
the extent so specified in the case of Section 501(4)), whether directly or indirectly by reason of
any reference elsewhere herein to any such Article or Section or by reason of any reference in any
such Article or Section to any other provision herein or in any other document, but the remainder
of this Indenture and the Securities of such shall be unaffected thereby.

     Section 1304. Conditions to Defeasance or Covenant Defeasance. 

     The following shall be the conditions to the application of Section 1302 or Section 1303 to
any Securities or the Outstanding Securities of any series:

63

 

     (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 benefit of the Holders of Outstanding Securities of such
series, (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 certified public accountants expressed in a
written certification thereof delivered to the Trustee, to pay and discharge, and which
shall be applied by the Trustee (or any such other qualifying trustee) to pay and discharge,
the principal of and any premium and interest on Outstanding Securities of such series 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 timely payment of which is unconditionally guaranteed as a full faith and
credit obligation by the United States of America, which, in either case under Clauses (i)
or (ii), is not callable or redeemable at the option of the issuer thereof, and (y) shall
also include a 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 1302 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 the Outstanding Securities of such series 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 1303 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 the Outstanding Securities of such
series will not recognize income, 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(5) and (6), at any time on or prior

64

 

to the 90th day after the date of such deposit (it being understood that this condition
shall not be deemed satisfied until after such 90th day).

     (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, the Indenture or any other agreement or instrument to
which the Company is a party or by which it is bound.

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

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

     Subject to the provisions of the last paragraph of Section 1003, all money and U.S. Government
Obligations (including the proceeds thereof) deposited with the Trustee or other qualifying trustee
(solely for purposes of this Section and Section 1306, the Trustee and any such other trustee are
referred to collectively as the “Trustee”) pursuant to Section 1304 in respect of any Securities
shall be held in trust and applied by the Trustee, in accordance with the provisions of such
Securities and this Indenture, to the payment, either directly or through any such Paying Agent
(including the Company 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 1304 or the
principal and interest received in respect thereof other than any such tax, fee or other charge
which by law is for the account of the Holders of Outstanding Securities.

     Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to
the Company and any Paying Agent upon Company Request any money or U.S. Government Obligations held
by it as provided in Section 1304 with respect to any Securities which, in the opinion of a
nationally recognized firm of independent certified 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.

65

 

     Section 1306. Reinstatement. 

     If the Trustee or the Paying Agent is unable to apply any money in accordance with this
Article with respect to any Securities by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such application, then the
Company’s obligations under this Indenture and such Securities from which the Company has been
discharged or released pursuant to Section 1302 or 1303 shall be revived and reinstated as though
no deposit had occurred pursuant to this Article with respect to such Securities, until such time
as the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section
1305 with respect to such Securities in accordance with this Article; provided,
however, that if the Company 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 FOURTEEN

convertible or exchangeable into shares of Common Stock of the Company, and the issuance of such
shares of Common Stock upon the conversion or exchange of such Securities, except as otherwise
specified as contemplated by Section 301 for the Securities of such series.

     Section 1402. Exercise of Conversion and Exchange Privilege. 

     In order to exercise a conversion or exchange privilege, the Holder of a Security of a series
with such a privilege shall surrender such Security to the Company at the office or agency
maintained for that purpose pursuant to Section 1002, accompanied by a duly executed conversion or
exchange notice to the Company substantially in the form set forth in Section 206 stating that the
Holder elects to convert or exchange such Security or a specified portion thereof. Such notice
shall also state, if different from the name and address of such Holder, the name or names (with
address) in which the certificate or certificates for shares of Common Stock which shall be
issuable on such conversion or exchange shall be issued. Securities surrendered for conversion or
exchange shall (if so required by the Company or the Trustee) be duly endorsed by or accompanied by
instruments of transfer in forms satisfactory to the Company and the Trustee duly executed by the
registered Holder or its attorney duly authorized in writing; and Securities so surrendered for
conversion or exchange (in whole or in part) during the period from the close of business on any
Regular Record Date to the opening of business on the next succeeding Interest Payment Date
(excluding Securities or portions thereof called for redemption during the period beginning at the
close of business on a Regular Record Date and ending at the opening of business on the first
Business Day after the next succeeding Interest Payment Date, or if such Interest Payment Date is
not a Business Day, the second such Business Day) shall also be accompanied by payment in funds
acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date
on the principal amount of such Security then being converted or exchanged, and such interest shall
be payable to such registered Holder notwithstanding the conversion or exchange of such Security,
subject to the provisions of Section 307 relating to the payment of Defaulted Interest by the
Company. As promptly as practicable after the receipt of such notice and of any payment required
pursuant to a Board Resolution and, subject to Section 303, set forth, or determined in the manner
provided, in an Officers’ Certificate, or established in one or more indentures supplemental hereto
setting forth the terms of such series of Security, and the surrender of such Security in
accordance with such reasonable regulations as the Company may prescribe, the Company shall issue
and shall deliver, at the office or agency at which such Security is surrendered, to such Holder or
on its written

66

 

order, a certificate or certificates for the number of full shares of Common Stock issuable
upon the conversion or exchange of such Security (or specified portion thereof), in accordance with
the provisions of such Board Resolution, Officers’ Certificate or supplemental indenture, and cash
as provided therein in respect of any fractional share of such Common Stock otherwise issuable upon
such conversion or exchange. Such conversion or exchange shall be deemed to have been effected
immediately prior to the close of business on the date on which such notice and such payment, if
required, shall have been received in proper order for conversion or exchange by the Company and
such Security shall have been surrendered as aforesaid (unless such Holder shall have so
surrendered such Security and shall have instructed the Company to effect the conversion or
exchange on a particular date following such surrender and such Holder shall be entitled to convert
or exchange such Security on such date, in which case such conversion or exchange shall be deemed
to be effected immediately prior to the close of business on such date) and at such time the rights
of the Holder of such Security as such Security Holder shall cease and the person or persons in
whose name or names any certificate or certificates for shares of Common Stock of the Company shall
be issuable upon such conversion or exchange shall be deemed to have become the Holder or Holders
of record of the shares represented thereby. Except as set forth above and subject to the final
paragraph of Section 307, no payment or adjustment shall be made upon any conversion or exchange on
account of any interest accrued on the Securities (or any part thereof) surrendered for conversion
or exchange or on account of any dividends on the Common Stock of the Company issued upon such
conversion or exchange.

     In the case of any Security which is converted or exchanged in part only, upon such conversion
or exchange the Company shall execute and the Trustee shall authenticate and deliver to or on the
order of the Holder thereof, at the expense of the Company, a new Security or Securities of the
same series, of authorized denominations, in aggregate principal amount equal to the unconverted or
unexchanged portion of such Security.

     Section 1403. No Fractional Shares. 

     No fractional share of Common Stock of the Company shall be issued upon conversions or
exchanges of Securities of any series. If more than one Security shall be surrendered for
conversion or exchange at one time by the same Holder, the number of full shares which shall be
issuable upon conversion or exchange shall be computed on the basis of the aggregate principal
amount of the Securities (or specified portions thereof to the extent permitted hereby) so
surrendered. If, except for the provisions of this Section 1403, any Holder of a Security or
Securities would be entitled to a fractional share of Common Stock of the Company upon the
conversion or exchange of such Security or Securities, or specified portions thereof, the Company
shall pay to such Holder an amount in cash equal to the current market value of such fractional
share computed (unless otherwise specified with respect to any series of Securities), (i) if such
Common Stock is listed or admitted to unlisted trading privileges on a national securities exchange
or market, on the basis of the last reported sale price regular way on such exchange or market on
the last trading day prior to the date of conversion or exchange upon which such a sale shall have
been effected, or (ii) if such Common Stock is not at the time so listed or admitted to unlisted
trading privileges on a national securities exchange or market, on the basis of the average of the
bid and asked prices of such Common Stock in the over-the counter market, on the last trading day
prior to the date of conversion or exchange, as reported by the National Quotation Bureau,
Incorporated or similar organization if the National Quotation Bureau, Incorporated is no longer
reporting such information, or if not so available, the fair market price as determined by the
Board of Directors. For purposes of this Section, “trading day” shall mean each Monday, Tuesday,
Wednesday, Thursday and Friday other than any day on which the Common Stock is not traded on the
New York Stock Exchange, or if the Common Stock is not traded on the New York Stock Exchange, on
the principal exchange or market on which the Common Stock is traded or quoted.

     Section 1404. Adjustment of Conversion and Exchange Price. 

     The conversion or exchange price of Securities of any series that is convertible or
exchangeable into Common Stock of the Company shall be adjusted for any stock dividends, stock
splits, reclassifications,

67

 

combinations or similar transactions in accordance with the terms of the supplemental
indenture or Board Resolutions setting forth the terms of the Securities of such series.

     Whenever the conversion or exchange price is adjusted, the Company shall compute the adjusted
conversion or exchange price in accordance with terms of the applicable Board Resolution or
supplemental indenture and shall prepare an Officers’ Certificate setting forth the adjusted
conversion or exchange price and showing in reasonable detail the facts upon which such adjustment
is based, and such certificate shall forthwith be filed at each office or agency maintained for the
purpose of conversion or exchange of Securities pursuant to Section 1002 and, if different, with
the Trustee. The Company shall forthwith cause a notice setting forth the adjusted conversion or
exchange price to be mailed, first class postage prepaid, to each Holder of Securities of such
series at its address appearing on the Security Register and to any conversion or exchange agent
other than the Trustee.

     Section 1405. Notice of Certain Corporate Actions. 

     In case:

     (1) the Company shall declare a dividend (or any other distribution) on its Common
Stock payable otherwise than in cash out of its retained earnings (other than a dividend for
which approval of any shareholders of the Company is required) that would require an
adjustment pursuant to Section 1404; or

     (2) the Company shall authorize the granting to all or substantially all of the holders
of its Common Stock of rights, options or warrants to subscribe for or purchase any shares
of capital stock of any class or of any other rights (other than any such grant for which
approval of any shareholders of the Company is required); or

     (3) of any reclassification of the Common Stock of the Company (other than a
subdivision or combination of its outstanding shares of Common Stock, or of any
consolidation, merger or share exchange to which the Company is a party and for which
approval of any shareholders of the Company is required), or of the sale of all or
substantially all of the assets of the Company; or

     (4) of the voluntary or involuntary dissolution, liquidation or winding up of the
Company; then the Company shall cause to be filed with the Trustee, and shall cause to be
mailed to all Holders at their last addresses as they shall appear in the Security Register,
at least 20 days (or 10 days in any case specified in Clause (1) or (2) above) prior to the
applicable record date hereinafter specified, a notice stating (i) the date on which a
record is to be taken for the purpose of such dividend, distribution, rights, options or
warrants, or, if a record is not to be taken, the date as of which the holders of Common
Stock of record to be entitled to such dividend, distribution, rights, options or warrants
are to be determined, or (ii) the date on which such reclassification, consolidation,
merger, share exchange, sale, dissolution, liquidation or winding up is expected to become
effective, and the date as of which it is expected that holders of Common Stock of record
shall be entitled to exchange their shares of Common Stock for securities, cash or other
property deliverable upon such reclassification, consolidation, merger, share exchange,
sale, dissolution, liquidation or winding up. If at any time the Trustee shall not be the
conversion or exchange agent, a copy of such notice shall also forthwith be filed by the
Company with the Trustee.

68

 

     Section 1406. Reservation of Shares of Common Stock. 

     The Company shall at all times reserve and keep available, free from preemptive rights, out of
its authorized but unissued Common Stock, for the purpose of effecting the conversion or exchange
of Securities, the full number of shares of Common Stock of the Company then issuable upon the
conversion or exchange of all outstanding Securities of any series that has conversion or exchange
rights.

     Section 1407. Payment of Certain Taxes Upon Conversion and Exchange. 

     Except as provided in the next sentence, the Company will pay any and all taxes that may be
payable in respect of the issue or delivery of shares of its Common Stock on conversion or exchange
of Securities pursuant hereto. The Company shall not, however, be required to pay any tax which may
be payable in respect of any transfer involved in the issue and delivery of shares of its Common
Stock in a name other than that of the Holder of the Security or Securities to be converted or
exchanged, and no such issue or delivery shall be made unless and until the person requesting such
issue has paid to the Company the amount of any such tax, or has established, to the satisfaction
of the Company, that such tax has been paid.

     Section 1408. Nonassessability. 

     The Company covenants that all shares of its Common Stock which may be issued upon conversion
or exchange of Securities will upon issue in accordance with the terms hereof be duly and validly
issued and fully paid and nonassessable.

     Section 1409. Provision in Case of Consolidation, Merger or Sale of Assets. 

     In case of any consolidation or merger of the Company with or into any other Person in a
transaction in which the Company is not the surviving Person, any merger of another Person with or
into the Company (other than a merger which does not result in any reclassification, conversion,
exchange or cancellation of outstanding shares of Common Stock of the Company) or any conveyance,
sale, transfer or lease of all or substantially all of the property or assets of the Company in a
single transaction or a series of related transactions, the Person formed by such consolidation or
resulting from such merger or which acquires such assets, as the case may be, shall execute and
deliver to the Trustee a supplemental indenture providing that the Holder of each Security of a
series then Outstanding that is convertible or exchangeable into Common Stock of the Company shall
have the right thereafter (which right shall be the exclusive conversion or exchange right
thereafter available to said Holder), during the period such Security shall be convertible or
exchangeable, to convert or exchange such Security only into the kind and amount of securities,
cash and other property receivable upon such consolidation, merger, conveyance, sale, transfer or
lease by a holder of the number of shares of Common Stock of the Company into which such Security
might have been converted or exchanged immediately prior to such consolidation, merger, conveyance,
sale, transfer or lease, assuming such holder of Common Stock of the Company (i) is not a Person
with which the Company consolidated or merged with or into or which merged into or with the Company
or to which such conveyance, sale, transfer or lease was made, as the case may be (a “Constituent
Person”), or an Affiliate of a Constituent Person and (ii) failed to exercise his rights of
election, if any, as to the kind or amount of securities, cash and other property receivable upon
such consolidation, merger, conveyance, sale, transfer or lease (provided that if
the kind or amount of securities, cash and other property receivable upon such consolidation,
merger, conveyance, sale, transfer, or lease is not the same for each share of Common Stock of the
Company held immediately prior to such consolidation, merger, conveyance, sale, transfer or lease
by others than a Constituent Person or an Affiliate thereof and in respect of which such rights of
election shall not have been exercised (“Non-electing Share”), then for the purpose of this Section
1409 the kind and amount of securities, cash and other property receivable upon such consolidation,
merger,

69

 

conveyance, sale, transfer or lease by the holders of each Non-electing Share shall be deemed
to be the kind and amount so receivable per share by a plurality of the Non-electing Shares). Such
supplemental indenture shall provide for adjustments which, for events subsequent to the effective
date of such supplemental indenture, shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article or in accordance with the terms of the supplemental
indenture or Board Resolutions setting forth the terms of such adjustments. The above provisions of
this Section 1409 shall similarly apply to successive consolidations, mergers, conveyances, sales,
transfers or leases. Notice of the execution of such a supplemental indenture shall be given by the
Company to the Holder of each Security of a series that is convertible or exchangeable into Common
Stock of the Company as provided in Section 106 promptly upon such execution.

     Neither the Trustee nor any conversion or exchange agent, if any, shall be under any
responsibility to determine the correctness of any provisions contained in any such supplemental
indenture relating either to the kind or amount of shares of stock or other securities or property
or cash receivable by Holders of Securities of a series convertible or exchangeable into Common
Stock of the Company upon the conversion or exchange of their Securities after any such
consolidation, merger, conveyance, transfer, sale or lease or to any such adjustment, but may
accept as conclusive evidence of the correctness of any such provisions, and shall be protected in
relying upon, an Opinion of Counsel with respect thereto, which the Company shall cause to be
furnished to the Trustee upon request.

     Section 1410. Duties of Trustee Regarding Conversion and Exchange. 

     Neither the Trustee nor any conversion or exchange agent shall at any time be under any duty
or responsibility to any Holder of Securities of any series that is convertible or exchangeable
into Common Stock of the Company to determine whether any facts exist which may require any
adjustment of the conversion or exchange price, or with respect to the nature or extent of any such
adjustment when made, or with respect to the method employed, whether herein or in any supplemental
indenture (or whether any provisions of any supplemental indenture are correct), any resolutions of
the Board of Directors or written instrument executed by one or more officers of the Company
provided to be employed in making the same. Neither the Trustee nor any conversion or exchange
agent shall be accountable with respect to the validity or value (or the kind or amount) of any
shares of Common Stock of the Company, or of any securities or property, which may at any time be
issued or delivered upon the conversion or exchange of any Securities and neither the Trustee nor
any conversion or exchange agent makes any representation with respect thereto. Subject to the
provisions of Section 601, neither the Trustee nor any conversion or exchange agent shall be
responsible for any failure of the Company to issue, transfer or deliver any shares of its Common
Stock or stock certificates or other securities or property upon the surrender of any Security for
the purpose of conversion or exchange or to comply with any of the covenants of the Company
contained in this Article Fourteen or in the applicable supplemental indenture, resolutions of the
Board of Directors or written instrument executed by one or more duly authorized officers of the
Company.

     Section 1411. Repayment of Certain Funds Upon Conversion and Exchange. 

     Any funds which at any time shall have been deposited by the Company or on its behalf with the
Trustee or any other paying agent for the purpose of paying the principal of, and premium, if any,
and interest, if any, on any of the Securities (including, but not limited to, funds deposited for
the sinking fund referred to in Article Twelve hereof and funds deposited pursuant to Article
Thirteen hereof) and which shall not be required for such purposes because of the conversion or
exchange of such Securities as provided in this Article Fourteen shall after such conversion or
exchange be repaid to the Company by the Trustee upon the Company’s written request.

ARTICLE FIFTEEN

GUARANTEE

     Section 1501. Unconditional Guarantee. 

     (1) Notwithstanding any provision of this Article Fifteen to the contrary, the
provisions of this Article Fifteen shall be applicable only to, and inure solely to the
benefit of, the Securities of any series designated, pursuant to Section 301, as entitled to
the benefits of the Guarantee of each of the Guarantors.

     (2) For value received, each of the Guarantors hereby jointly and severally, fully,
unconditionally and absolutely guarantees (the “Guarantee”) to the Holders and to the
Trustee the due and punctual payment of the principal of, and premium, if any, and interest
on the Securities and all other amounts due and payable under this Indenture and the
Securities by the Company, when and as such principal, premium, if any, and interest shall
become due and payable, whether at the Stated Maturity or by declaration of acceleration,
call for redemption or otherwise, according to the terms of the Securities and this
Indenture, subject to the limitations set forth in Section 1503.

     (3) Failing payment when due of any amount guaranteed pursuant to the Guarantee, for
whatever reason, each of the Guarantors will be jointly and severally obligated to pay the
same immediately. The Guarantee hereunder is intended to be a general, unsecured, senior
obligation of each of the Guarantors and will rank pari passu in right of payment with all
Debt of each Guarantor that is not, by its terms, expressly subordinated in right of payment
to the Guarantee. Each of the Guarantors hereby agrees that its obligations hereunder shall
be full, unconditional and absolute, irrespective of the validity, regularity or
enforceability of the Securities, the Guarantee (including the Guarantee of any other
Guarantor) or this Indenture, the absence of any action to enforce the same, any waiver or
consent by any Holder of the Securities with respect to any provisions hereof or thereof,
the recovery of any judgment against the Company or any other Guarantor, or any action to
enforce the same or any other circumstances which might otherwise constitute a legal or
equitable discharge or defense of any of the Guarantors. Each of the Guarantors hereby
agrees that in the event of a default in payment of the principal of, or premium, if any, or
interest on the Securities, whether at the Stated Maturity or by declaration of
acceleration, call for redemption or otherwise, legal proceedings may be instituted by the
Trustee on behalf of the Holders or, subject to Section 507, by the Holders, on the terms
and conditions set forth in this Indenture, directly against such Guarantor to enforce the
Guarantee without first proceeding against the Company or any other Guarantor.

     (4) The obligations of each of the Guarantors under this Article Fifteen shall be as
aforesaid full, unconditional and absolute and shall not be impaired, modified, released or
limited by any occurrence or condition whatsoever, including (i) any compromise, settlement,
release, waiver, renewal, extension, indulgence or modification of, or any change in, any of
the obligations and liabilities of the Company or any of the Guarantors contained in the
Securities or this Indenture, (ii) any impairment, modification, release or limitation of
the liability of the Company, any of the Guarantors or any of their estates in bankruptcy,
or any remedy for the enforcement thereof, resulting from the operation of any present or
future provision of any applicable Federal or State bankruptcy, insolvency, reorganization
or similar law, or other statute or from the decision of any court, (iii) the assertion or
exercise by the Company, any of the Guarantors or the Trustee of any rights or remedies
under the Securities or this Indenture or their delay in or failure to assert or exercise
any such rights or remedies, (iv) the assignment or the purported assignment of any property
as security for the Securities, including all or any part of the rights of the Company or
any of the Guarantors under this Indenture, (v) the extension of the time for payment by the
Company or any of the Guarantors of any payments or other sums or any part thereof owing or
payable under any of the terms and provisions of the Securities or this Indenture or of the
time for performance by the Company or any of

71

 

the Guarantors of any other obligations under or arising out of any such terms and
provisions or the extension or the renewal of any thereof, (vi) the modification or
amendment (whether material or otherwise) of any duty, agreement or obligation of the
Company or any of the Guarantors set forth in this Indenture, (vii) the voluntary or
involuntary liquidation, dissolution, sale or other disposition of all or substantially all
of the assets, marshaling of assets and liabilities, receivership, insolvency, bankruptcy,
assignment for the benefit of creditors, reorganization, arrangement, composition or
readjustment of, or other similar proceeding affecting, the Company or any of the Guarantors
or any of their respective assets, or the disaffirmance of the Securities, the Guarantee or
this Indenture in any such proceeding, (viii) the release or discharge of the Company or any
of the Guarantors from the performance or observance of any agreement, covenant, term or
condition contained in any of such instruments by operation of law, (ix) the
unenforceability of the Securities, the Guarantee or this Indenture or (x) any other
circumstances (other than payment in full or discharge of all amounts guaranteed pursuant to
the Guarantee) which might otherwise constitute a legal or equitable discharge of a surety
or guarantor.

     (5) Each of the Guarantors hereby (i) waives diligence, presentment, demand of payment,
filing of claims with a court in the event of the merger, bankruptcy, insolvency or
reorganization of the Company or any of the Guarantors, and all demands whatsoever, (ii)
acknowledges that any agreement, instrument or document evidencing the Guarantee may be
transferred and that the benefit of its obligations hereunder shall extend to each holder of
any agreement, instrument or document evidencing the Guarantee without notice to it and
(iii) covenants that the Guarantee will not be discharged except by complete performance of
the Guarantee. Each of the Guarantors further agrees that if at any time all or any part of
any payment theretofore applied by any Person to the Guarantee is, or must be, rescinded or
returned for any reason whatsoever, including the bankruptcy, insolvency or reorganization
of the Company or any of the Guarantors, the Guarantee shall, to the extent that such
payment is or must be rescinded or returned, be deemed to have continued in existence
notwithstanding such application, and the Guarantee shall continue to be effective or be
reinstated, as the case may be, as though such application had not been made.

     (6) Each of the Guarantors shall be subrogated to all rights of the Holders and the
Trustee against the Company in respect of any amounts paid by such Guarantor pursuant to the
provisions of this Indenture, provided, however, that such Guarantor, shall
not be entitled to enforce or to receive any payments arising out of, or based upon, such
right of subrogation until all of the Securities and the Guarantee shall have been paid in
full or discharged.

     Section 1502. Execution and Delivery of Guarantee. 

     To further evidence the Guarantee set forth in Section 1501, each of the Guarantors hereby
agrees that a notation relating to such Guarantee, substantially in the form attached hereto as
Annex A, shall be endorsed on each Security entitled to the benefits of the Guarantee authenticated
and delivered by the Trustee and executed by either manual or facsimile signature of an officer of
such Guarantor, or in the case of a Guarantor that is a limited partnership, an officer of the
general partner of each Guarantor, or in the case of a Guarantor that is a limited liability
company, an officer or manager of such Guarantor. Each of the Guarantors hereby agrees that the
Guarantee set forth in Section 1501 shall remain in full force and effect notwithstanding any
failure to endorse on each Security a notation relating to the Guarantee. If any officer of any
Guarantor, or in the case of a Guarantor that is a limited partnership, any officer of the general
partner of the Guarantor, or in the case of a Guarantor that is a limited liability company, an
officer or manager of such Guarantor, whose signature is on this Indenture or a Security no longer
holds that office at the time the Trustee authenticates such Security or at any time thereafter,
the Guarantee of such Security shall be valid nevertheless. The delivery of any Security by the
Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee
set forth in this Indenture on behalf of the Guarantors.

     The Trustee hereby accepts the trusts in this Indenture upon the terms and conditions herein
set forth.

72

 

     Section 1503. Limitation on Guarantors’ Liability. 

     (1) Each Guarantor and by its acceptance hereof each Holder of a Security entitled to
the benefits of the Guarantee hereby confirm that it is the intention of all such parties
that the guarantee by such Guarantor pursuant to the Guarantee not constitute a fraudulent
transfer or conveyance for purposes of any Federal or State law. To effectuate the foregoing
intention, the Holders of a Security entitled to the benefits of the Guarantee and the
Guarantors hereby irrevocably agree that the obligations of each Guarantor under the
Guarantee shall be limited to the maximum amount as will, after giving effect to all other
contingent and fixed liabilities of such Guarantor and to any collections from or payments
made by or on behalf of any other Guarantor in respect of the obligations of such other
Guarantor under the Guarantee, not result in the obligations of such Guarantor under the
Guarantee constituting a fraudulent conveyance or fraudulent transfer under Federal or State
law.

     (2) The Guarantee is expressly limited so that in no event, including the acceleration
of the maturity of the Securities, shall the amount paid or agreed to be paid in respect of
interest on the Securities (or fees or other amounts deemed payment for the use of funds)
exceed the maximum permissible amount under applicable law, as in effect on the date hereof
and as subsequently amended or modified to allow a greater amount of interest (or fees or
other amounts deemed payment for the use of funds) to be paid under the Guarantee. If for
any reason the amount in respect of interest (or fees or other amounts deemed payment for
the use of funds) required by the Guarantee exceeds such maximum permissible amount, the
obligation to pay interest under the Guarantee (or fees or other amounts deemed payment for
the use of funds) shall be automatically reduced to such maximum permissible amount and any
amounts collected by any holder of any Security in excess of the permissible amount shall be
automatically applied to reduce the outstanding principal on such Security.

     Section 1504. Release of Guarantors from Guarantee. 

     (1) Notwithstanding any other provisions of this Indenture, the Guarantee of any
Guarantor may be released upon the terms and subject to the conditions set forth in Section
1302 and in this Section 1504. Provided that no Default shall have occurred and shall be
continuing under this Indenture, the Guarantee issued by a Guarantor pursuant to this
Article Fifteen shall be unconditionally released and discharged: (i) automatically upon (A)
any sale, exchange or transfer, whether by way of merger or otherwise, to any Person that is
not an Affiliate of the Company, of all of the Company’s direct or indirect limited
partnership or other equity interests in such Guarantor (provided such sale, exchange or
transfer is not prohibited by this Indenture) or (B) the merger of such Guarantor into the
Company or any other Guarantor or the liquidation and dissolution of such Guarantor (in each
case to the extent not prohibited by this Indenture); or (ii) as set forth in an applicable
indenture supplemental hereto.

     (2) The Trustee shall deliver an appropriate instrument evidencing any release of a
Guarantor from the Guarantee upon receipt of a written request of the Company accompanied by
an Officers’ Certificate and an Opinion of Counsel to the effect that the Guarantor is
entitled to such release in accordance with the provisions of this Indenture. Any Guarantor
not so released shall remain liable for the full amount of principal of (and premium, if
any) and interest on the Securities entitled to the benefits of the Guarantee as provided in
this Indenture, subject to the limitations of Section 1503.

73

 

     Section 1505. Guarantor Contribution. 

     In order to provide for just and equitable contribution among the Guarantors, the Guarantors
hereby agree, inter se, that in the event any payment or distribution is made by any Guarantor (a
“Funding Guarantor”) under the Guarantee, such Funding Guarantor shall be entitled to a
contribution from each other Guarantor (if any) in a pro rata amount based on the net assets of
each Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by
that Funding Guarantor in discharging the Company’s obligations with respect to the Securities or
any other Guarantor’s obligations with respect to the Guarantee.
