and (subject to Section 2.03) set forth, or determined in the manner provided, in the Officers’
Certificate or Company Order referred to above or in any such indenture supplemental hereto.

Resolution, a copy of an appropriate record of such action, together with such Board Resolution,
shall be set forth in an Officers’ Certificate or 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’

10

 

SECTION 2.03 Forms Generally.

          The Securities of each series shall be in fully registered form and in substantially such form
or forms (including temporary or permanent global form) established by or pursuant to a Board
Resolution or in one or more indentures supplemental hereto. The Securities may have notations,
legends or endorsements required by law, securities exchange rule, the Company’s certificate of
incorporation, bylaws or other similar governing documents, agreements to which the Company is
subject, if any, or usage (provided that any such notation, legend or endorsement is in a form
acceptable to the Company). A copy of the Board Resolution establishing the form or forms of
Securities of any series shall be delivered to the Trustee at or prior to the delivery of the
Company Order contemplated by Section 2.04 for the authentication and delivery of such Securities.

          The definitive Securities of each series shall be printed, lithographed or engraved on steel
engraved borders or may be produced in any other manner, all as determined by the Officers
executing such Securities, as evidenced by their execution thereof.

          The Trustee’s certificate of authentication shall be in substantially the following form:

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

	 	 	 	 	 
	 	Wells Fargo Bank, National Association, as Trustee

 	 
	 	By:  	 	 
	 	 	Authorized Signatory". 	 
	 	 	 	 
	 

SECTION 2.04 Execution, Authentication, Delivery and Dating.

          Two Officers of the Company shall sign the Securities on behalf of the Company and, with
respect to any related Guarantee, an Officer of each Subsidiary Guarantor shall sign the Notation
of Guarantee on behalf of such Subsidiary Guarantor, in each case by manual or facsimile signature.
If an Officer of the Company whose signature is on a Security no longer holds that office at the
time the Security is authenticated, the Security shall be valid nevertheless.

          A Security shall not be entitled to any benefit under this Indenture or the related
Guarantees, if any, or be valid or obligatory for any purpose until authenticated by the manual
signature of an authorized signatory of the Trustee, which signature shall be conclusive evidence
that the Security has been authenticated under this Indenture. Notwithstanding the foregoing, if
any Security has been authenticated and delivered hereunder but never issued and sold by the
Company, and the Company delivers such Security to the Trustee for cancellation as provided in
Section 2.13, together with a written statement (which need not comply with Section 12.05 and need
not be accompanied by an Opinion of Counsel) stating that such Security has never been issued and
sold by the Company, 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 or the related Guarantees, if any.

11

 

          At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Securities of any series executed by the Company to the Trustee for
authentication, and the Trustee shall authenticate and deliver such Securities for original issue
upon a Company Order for the authentication and delivery of such Securities or pursuant to such
procedures acceptable to the Trustee as may be specified from time to time by Company Order. Such
order shall specify the amount of the Securities to be authenticated, the date on which the
original issue of Securities is to be authenticated, the name or names of the initial Holder or
Holders and any other terms of the Securities of such series not otherwise determined. If provided
for in such procedures, such Company Order may authorize (1) authentication and delivery of
Securities of such series for original issue from time to time, with certain terms (including,
without limitation, the Maturity dates or dates, original issue date or dates and interest rate or
rates) that differ from Security to Security and (2) may authorize authentication and delivery
pursuant to oral or electronic instructions from the Company or its duly authorized agent, which
instructions shall be promptly confirmed in writing.

          If the form or terms of the Securities of the series have been established in or pursuant to
one or more Board Resolutions as permitted by Section 2.01, in authenticating such Securities, and
accepting the additional responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive (in addition to the Company Order referred to above and the
other documents required by Section 12.04), and (subject to Section 7.01) shall be fully protected
in relying upon:

     (a) an Officers’ Certificate setting forth the Board Resolution and, if applicable, an
appropriate record of any action taken pursuant thereto, as contemplated by the last
paragraph of Section 2.01; and

     (b) an Opinion of Counsel to the effect that:

     (i) the form of such Securities has been established in conformity with the
provisions of this Indenture;

     (ii) the terms of such Securities have been established in conformity with the
provisions of this Indenture; and

     (iii) that such Securities and the related Guarantees, if any, 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 binding obligations of the Company and the Subsidiary Guarantors,
respectively, enforceable against the Company and the Subsidiary Guarantors,
respectively, in accordance with their respective terms, except as the
enforceability thereof may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, fraudulent conveyance or other similar laws in effect
from time to time affecting the rights of creditors generally, and the application
of general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law).

12

 

          If all the Securities of any series are not to be issued at one time, it shall not be
necessary to deliver an Officers’ Certificate and Opinion of Counsel at the time of issuance of
each such Security, but such Officers’ Certificate and Opinion of Counsel shall be delivered at or
before the time of issuance of the first Security of the series to be issued.

          The Trustee shall not be required to authenticate such Securities if the issuance of such
Securities pursuant to this Indenture would affect the Trustee’s own rights, duties or immunities
under the Securities and this Indenture or otherwise in a manner not reasonably acceptable to the
Trustee.

          The Trustee may appoint an authenticating agent acceptable to the Company to authenticate
Securities. Unless limited by the terms of such appointment, an authenticating agent may
authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An authenticating agent has
the same rights as an Agent to deal with the Company, any Subsidiary Guarantor or any other
Affiliate of the Company.

          Each Security shall be dated the date of its authentication.

SECTION 2.05 Registrar and Paying Agent.

          The Company shall maintain an office or agency for each series of Securities where Securities
of such series may be presented for registration of transfer or exchange (“Registrar”) and an
office or agency where Securities of such series may be presented for payment (“Paying Agent”).
The Registrar shall keep a register of the Securities of such series and of their transfer and
exchange. The Company may appoint one or more co-registrars and one or more additional paying
agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any
additional paying agent.

          The Company shall enter into an appropriate agency agreement with any Registrar or Paying
Agent not a party to this Indenture. The agreement shall implement the provisions of this
Indenture that relate to such Agent. The Company shall notify the Trustee of the name and address
of any Agent not a party to this Indenture. The Company may change any Paying Agent or Registrar
without notice to any Holder. If the Company fails to appoint or maintain another entity as
Registrar or Paying Agent, the Trustee shall act as such. The Company or any Subsidiary may act as
Paying Agent or Registrar.

          The Company initially appoints the Trustee as Registrar and Paying Agent.

SECTION 2.06 Paying Agent to Hold Money in Trust.

          The Company shall require each Paying Agent other than the Trustee to agree in writing that
the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the
Paying Agent for the payment of principal of, premium, if any, or interest on or any Additional
Amounts with respect to Securities and will notify the Trustee of any default by the Company in
making any such payment. While any such default continues, the Trustee may require a Paying Agent
to pay all money held by it to the Trustee and to account for any funds disbursed. The Company at
any time may require a Paying Agent to pay all money held

13

 

by it to the Trustee and to account for any funds disbursed. Upon payment over to the Trustee
and upon accounting for any funds disbursed, the Paying Agent (if other than the Company, a
Subsidiary Guarantor or another Subsidiary) shall have no further liability for the money. If the
Company or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund
for the benefit of the Holders all money held by it as Paying Agent. Each Paying Agent shall
otherwise comply with TIA § 317(b).

SECTION 2.07 Holder Lists.

          The Trustee shall preserve in as current a form as is reasonably practicable the most recent
list available to it of the names and addresses of Holders and shall otherwise comply with TIA
§ 312(a). If the Trustee is not the Registrar with respect to a series of Securities, the Company
shall furnish to the Trustee at least five Business Days before each Interest Payment Date with
respect to such series of Securities, and at such other times as the Trustee may request in
writing, a list in such form and as of such date as the Trustee may reasonably require of the names
and addresses of Holders of such series, and the Company shall otherwise comply with TIA § 312(a).

SECTION 2.08 Transfer and Exchange.

          Except as set forth in Section 2.17 or as may be provided pursuant to Section 2.01:

          When Securities of any series are presented to the Registrar with the request to register the
transfer of such Securities or to exchange such Securities for an equal principal amount of
Securities of the same series of like tenor and of other authorized denominations, the Registrar
shall register the transfer or make the exchange as requested if its requirements and the
requirements of this Indenture for such transactions are met; provided, however, that the
Securities presented or surrendered for registration of transfer or exchange shall be duly endorsed
or accompanied by a written instruction of transfer in form reasonably satisfactory to the
Registrar duly executed by the Holder thereof or by his attorney, duly authorized in writing, on
which instruction the Registrar can rely.

          To permit registrations of transfers and exchanges, the Company shall execute and the Trustee
shall authenticate Securities at the Registrar’s written request and submission of the Securities
or Global Securities. No service charge shall be made to a Holder for any registration of transfer
or exchange (except as otherwise expressly permitted herein), but the Company may require payment
of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection
therewith (other than such transfer tax or similar governmental charge payable upon exchanges
pursuant to Section 2.12, 3.07 or 9.05). The Trustee shall authenticate Securities in accordance
with the provisions of Section 2.04. Notwithstanding any other provisions of this Indenture to the
contrary, the Company shall not be required to register the transfer or exchange of (a) any
Security selected for redemption in whole or in part pursuant to Article III, except the unredeemed
portion of any Security being redeemed in part, or (b) any Security during the period beginning 15
Business Days prior to the mailing of notice of any offer to repurchase Securities of the series
required pursuant to the terms thereof or

14

 

of redemption of Securities of a series to be redeemed and ending at the close of business on
the day of mailing.

SECTION 2.09 Replacement Securities.

          If any mutilated Security is surrendered to the Trustee, or if the Holder of a Security claims
that the Security has been destroyed, lost or stolen and the Company and the Trustee receive
evidence to their satisfaction of the destruction, loss or theft of such Security, the Company
shall issue and the Trustee shall authenticate a replacement Security of the same series if the
Trustee’s requirements are met. If 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. If required by the Trustee, any Subsidiary Guarantor or the
Company, such Holder must furnish an indemnity bond that is sufficient in the judgment of the
Trustee and the Company to protect the Company, each Subsidiary Guarantor, the Trustee, any Agent
or any authenticating agent from any loss that any of them may suffer if a Security is replaced.
The Company and the Trustee may charge a Holder for their expenses in replacing a Security.

          Every replacement Security is an additional obligation of the Company.

SECTION 2.10 Outstanding Securities.

          The Securities outstanding at any time are all the Securities authenticated by the Trustee
except for those canceled by it, those delivered to it for cancellation, those reductions in the
interest in a Global Security effected by the Trustee hereunder and those described in this
Section 2.10 as not outstanding.

          If a Security is replaced pursuant to Section 2.09, it ceases to be outstanding unless the
Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide
purchaser.

          If the principal amount of any Security is considered paid under Section 4.01, it ceases to be
outstanding and interest on it ceases to accrue.

          A Security does not cease to be outstanding because the Company, a Subsidiary Guarantor or
another Affiliate of the Company or an Affiliate of a Subsidiary Guarantor holds the Security.

SECTION 2.11 Original Issue Discount, Foreign-Currency Denominated and Treasury Securities.

          In determining whether the Holders of the required principal amount of Securities have
concurred in any direction, amendment, supplement, waiver or consent, (a) the principal amount of
an Original Issue Discount Security shall be the principal amount thereof that would be due and
payable as of the date of such determination upon acceleration of the Maturity thereof pursuant to
Section 6.02, (b) the principal amount of a Security denominated in a foreign currency shall be the
Dollar equivalent, as determined by the Company by reference to the noon buying rate in The City of
New York for cable transfers for such currency, as such rate is

15

 

certified for customs purposes by the Federal Reserve Bank of New York (the “Exchange Rate”)
on the date of original issuance of such Security, of the principal amount (or, in the case of an
Original Issue Discount Security, the Dollar equivalent, as determined by the Company by reference
to the Exchange Rate on the date of original issuance of such Security, of the amount determined as
provided in (a) above), of such Security and (c) Securities owned by the Company, a Subsidiary
Guarantor or any other obligor upon the Securities or any Affiliate of the Company or a Subsidiary
Guarantor or of such other obligor shall be disregarded, except that, for the purpose of
determining whether the Trustee shall be protected in relying upon any such direction, amendment,
supplement, waiver or consent, only Securities that a Responsible Officer of the Trustee actually
knows are so owned shall be so disregarded.

SECTION 2.12 Temporary Securities.

          Until definitive Securities of any series are ready for delivery, the Company may prepare and
the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially
in the form of definitive Securities, but may have variations that the Company considers
appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and
the Trustee shall authenticate definitive Securities in exchange for temporary Securities. Until
so exchanged, the temporary Securities shall in all respects be entitled to the same benefits under
this Indenture as definitive Securities.

SECTION 2.13 Cancellation.

          The Company or any Subsidiary Guarantor at any time may deliver Securities to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities
surrendered to them for registration of transfer, exchange, payment or redemption or for credit
against any sinking fund payment. The Trustee shall cancel all Securities surrendered for
registration of transfer, exchange, payment, redemption, replacement or cancellation or for credit
against any sinking fund. Unless the Company shall direct in writing that canceled Securities be
returned to it, after written notice to the Company all canceled Securities held by the Trustee
shall be disposed of in accordance with the usual disposal procedures of the Trustee, and the
Trustee shall maintain a record of their disposal. The Company may not issue new Securities to
replace Securities that have been paid or that have been delivered to the Trustee for cancellation.

SECTION 2.14 Payments; Defaulted Interest.

          Unless otherwise provided as contemplated by Section 2.01, interest (except defaulted
interest) on any Security that is payable, and is punctually paid or duly provided for, on any
Interest Payment Date shall be paid to the Persons who are registered Holders of that Security at
the close of business on the record date next preceding such Interest Payment Date, even if such
Securities are canceled after such record date and on or before such Interest Payment Date. The
Holder must surrender a Security to a Paying Agent to collect principal payments. Unless otherwise
provided with respect to the Securities of any series, the Company will pay the principal of,
premium (if any) and interest on and any Additional Amounts with respect to the Securities in
Dollars. Such amounts shall be payable at the offices of the Trustee or any Paying Agent, provided
that at the option of the Company, the Company may pay such

16

 

amounts (1) by wire transfer with respect to Global Securities or (2) by check payable in such
money mailed to a Holder’s registered address with respect to any Securities.

          If the Company defaults in a payment of interest on the Securities of any series, the Company
shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest on the
defaulted interest, in each case at the rate provided in the Securities of such series and in
Section 4.01. The Company may pay the defaulted interest to the Persons who are Holders on a
subsequent special record date. At least 15 days before any special record date selected by the
Company, the Company (or the Trustee, in the name of and at the expense of the Company upon 20
days’ prior written notice from the Company setting forth such special record date and the interest
amount to be paid) shall mail to Holders a notice that states the special record date, the related
payment date and the amount of such interest to be paid.

SECTION 2.15 Persons Deemed Owners.

          The Company, the Subsidiary Guarantors, the Trustee, any Agent and any authenticating agent
may treat the Person in whose name any Security is registered as the owner of such Security for the
purpose of receiving payments of principal of, premium (if any) or interest on or any Additional
Amounts with respect to such Security and for all other purposes. None of the Company, any
Subsidiary Guarantor, the Trustee, any Agent or any authenticating agent shall be affected by any
notice to the contrary.

SECTION 2.16 Computation of Interest.

          Except as otherwise specified as contemplated by Section 2.01 for Securities of any series,
interest on the Securities of each series shall be computed on the basis of a year comprising
twelve 30-day months.

SECTION 2.17 Global Securities; Book-Entry Provisions.

          If Securities of a series are issuable in global form as a Global Security, as contemplated by
Section 2.01, then, notwithstanding clause (10) of Section 2.01 and the provisions of Section 2.02,
any such Global Security shall represent such of the outstanding Securities of such series as shall
be specified therein and may provide that it shall represent the aggregate amount of outstanding
Securities from time to time endorsed thereon and that the aggregate amount of outstanding
Securities represented thereby may from time to time be reduced or increased, as appropriate, to
reflect exchanges, transfers or redemptions. Any endorsement of a Global Security to reflect the
amount, or any increase or decrease in the amount, of outstanding Securities represented thereby
shall be made by the Trustee (i) in such manner and upon instructions given by such Person or
Persons as shall be specified in such Security or in a Company Order to be delivered to the Trustee
pursuant to Section 2.04 or (ii) otherwise in accordance with written instructions or such other
written form of instructions as is customary for the Depositary for such Security, from such
Depositary or its nominee on behalf of any Person having a beneficial interest in such Global
Security. Subject to the provisions of Section 2.04 and, if applicable, Section 2.12, the Trustee
shall deliver and redeliver any Security in permanent global form in the manner and upon
instructions given by the Person or Persons specified in such Security or in the applicable Company
Order. With respect to the Securities of

17

 

any series that are represented by a Global Security, the Company and the Subsidiary
Guarantors authorize the execution and delivery by the Trustee of a letter of representations or
other similar agreement or instrument in the form customarily provided for by the Depositary
appointed with respect to such Global Security. Any Global Security may be deposited with the
Depositary or its nominee, or may remain in the custody of the Trustee or the Security Custodian
therefor pursuant to a FAST Balance Certificate Agreement or similar agreement between the Trustee
and the Depositary. If a Company Order has been, or simultaneously is, delivered, any instructions
by the Company with respect to endorsement or delivery or redelivery of a Security in global form
shall be in writing but need not comply with Section 12.05 and need not be accompanied by an
Opinion of Counsel.

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

          Notwithstanding Section 2.08, and except as otherwise provided pursuant to Section 2.01:
Transfers of a Global Security shall be limited to transfers of such Global Security in whole, but
not in part, to the Depositary, its successors or their respective nominees. Interests of
beneficial owners in a Global Security may be transferred in accordance with the rules and
procedures of the Depositary. Securities shall be transferred to all beneficial owners in exchange
for their beneficial interests in a Global Security if, and only if, either (1) the Depositary
notifies the Company that it is unwilling or unable to continue as Depositary for the Global
Security and a successor Depositary is not appointed by the Company within 90 days of such notice,
(2) an Event of Default has occurred with respect to such series and is continuing and the
Registrar has received a request from the Depositary to issue Securities in lieu of all or a
portion of the Global Security (in which case the Company shall deliver Securities within 30 days
of such request) or (3) the Company determines not to have the Securities represented by a Global
Security.

          In connection with any transfer of a portion of the beneficial interests in a Global Security
to beneficial owners pursuant to this Section 2.17, the Registrar shall reflect on its books and
records the date and a decrease in the principal amount of the Global Security in an amount equal
to the principal amount of the beneficial interests in the Global Security to be transferred, and
the Company shall execute, and the Trustee upon receipt of a Company Order

18

 

for the authentication and delivery of Securities shall authenticate and deliver, one or more
Securities of the same series of like tenor and amount.

          In connection with the transfer of all the beneficial interests in a Global Security to
beneficial owners pursuant to this Section 2.17, the Global Security shall be deemed to be
surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall
authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its
beneficial interests in the Global Security, an equal aggregate principal amount of Securities of
authorized denominations.

          None of the Company, any Subsidiary Guarantor, or the Trustee will have any responsibility or
liability for any aspect of the records relating to, or payments made on account of, Securities by
the Depositary, or for maintaining, supervising or reviewing any records of the Depositary relating
to such Securities. None of the Company, any Subsidiary Guarantor, or the Trustee shall be liable
for any delay by the related Global Security Holder or the Depositary in identifying the beneficial
owners, and each such Person may conclusively rely on, and shall be protected in relying on,
instructions from such Global Security Holder or the Depositary for all purposes (including with
respect to the registration and delivery, and the respective principal amounts, of the Securities
to be issued).

          The provisions of the last sentence of the third paragraph of Section 2.04 shall apply to any
Global Security if such Global Security was never issued and sold by the Company and the Company or
a Subsidiary Guarantor, delivers to the Trustee the Global Security together with written
instructions (which need not comply with Section 12.05 and need not be accompanied by an Opinion of
Counsel) with regard to the cancellation or reduction in the principal amount of Securities
represented thereby, together with the written statement contemplated by the last sentence of the
third paragraph of Section 2.04.

          Notwithstanding the provisions of Sections 2.03 and 2.14, unless otherwise specified as
contemplated by Section 2.01, payment of principal of, premium (if any) and interest on and any
Additional Amounts with respect to any Global Security shall be made to the Person or Persons
specified therein.

ARTICLE III

REDEMPTION

SECTION 3.01 Applicability of Article.

          Securities of any series that are redeemable before their Stated Maturity shall be redeemable
in accordance with their terms and (except as otherwise specified as contemplated by Section 2.01
for Securities of any series) in accordance with this Article III.

SECTION 3.02 Notice to the Trustee.

          If the Company elects to redeem Securities of any series pursuant to this Indenture, it shall
notify the Trustee of the Redemption Date and the principal amount of Securities of such series to
be redeemed. The Company shall so notify the Trustee at least 45

19

 

days before the Redemption Date (unless a shorter notice shall be satisfactory to the Trustee)
by delivering to the Trustee an Officers’ Certificate stating that such redemption will comply with
the provisions of this Indenture and of the Securities of such series. Any such notice may be
canceled at any time prior to the mailing of such notice of such redemption to any Holder and shall
thereupon be void and of no effect. A redemption or notice thereof may be subject to one or more
conditions.

SECTION 3.03 Selection of Securities To Be Redeemed.

          If less than all the Securities of any series are to be redeemed (unless all of the Securities
of such series of a specified tenor are to be redeemed), the particular Securities to be redeemed
shall be selected not more than 60 days prior to the Redemption Date by the Trustee from the
outstanding Securities of such series (and tenor) not previously called for redemption, either at
random, by lot or by such other method as the Trustee shall deem fair and appropriate and that may
provide for the selection for redemption of portions (equal to the minimum authorized denomination
for Securities of that series or any integral multiple thereof) of the principal amount of
Securities of such series of a denomination larger than the minimum authorized denomination for
Securities of that series or of the principal amount of Global Securities of such series.

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

          For purposes of this Indenture, unless the context otherwise requires, all provisions relating
to redemption of Securities shall relate, in the case of any of the Securities redeemed or to be
redeemed only in part, to the portion of the principal amount thereof which has been or is to be
redeemed.

SECTION 3.04 Notice of Redemption.

          Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than
30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed,
at the address of such Holder appearing in the register of Securities maintained by the Registrar.

          All notices of redemption shall identify the Securities to be redeemed and shall state:

     (1) the Redemption Date;

     (2) the Redemption Price;

     (3) that, unless the Company and the Subsidiary Guarantors default in making the
redemption payment, interest on Securities called for redemption ceases to accrue on and
after the Redemption Date, and the only remaining right of the Holders of such Securities is
to receive payment of the Redemption Price upon surrender to the Paying Agent of the
Securities redeemed;

20

 

     (4) if any Security is to be redeemed in part, the portion of the principal amount
thereof to be redeemed and that on and after the Redemption Date, upon surrender for
cancellation of such Security to the Paying Agent, a new Security or Securities in the
aggregate principal amount equal to the unredeemed portion thereof will be issued without
charge to the Holder;

     (5) that Securities called for redemption must be surrendered to the Paying Agent to
collect the Redemption Price and the name and address of the Paying Agent;

     (6) that the redemption is for a sinking or analogous fund, if such is the case;

     (7) the CUSIP number, if any, relating to such Securities; and

     (8) if the redemption or notice thereof is subject to one or more conditions, a
statement to such effect and the condition or conditions precedent.

          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 written request, by the Trustee in the name and at the
expense of the Company.

SECTION 3.05 Effect of Notice of Redemption.

          Once notice of redemption is mailed, unless the redemption or notice thereof is subject to one
or more conditions as specified in the notice, Securities called for redemption become due and
payable on the Redemption Date and at the Redemption Price. Upon surrender to the Paying Agent,
such Securities called for redemption shall be paid at the Redemption Price, but interest
installments whose maturity is on or prior to such Redemption Date will be payable on the relevant
Interest Payment Dates to the Holders of record at the close of business on the relevant record
dates specified pursuant to Section 2.01.

SECTION 3.06 Deposit of Redemption Price.

          On or prior to 11:00 a.m., New York City time, on any Redemption Date, the Company or a
Subsidiary Guarantor shall deposit with the Trustee or the Paying Agent (or, if the Company or a
Subsidiary Guarantor is acting as the Paying Agent, segregate and hold in trust as provided in
Section 2.06) an amount of money in same day funds sufficient to pay the Redemption Price of, and
(except if the Redemption Date shall be an Interest Payment Date) accrued interest on and any
Additional Amounts with respect to, the Securities or portions thereof which are to be redeemed on
that date, other than Securities or portions thereof called for redemption on that date which have
been delivered by the Company or a Subsidiary Guarantor to the Trustee for cancellation.

          If the Company or a Subsidiary Guarantor complies with the preceding paragraph, then, unless
the Company or the Subsidiary Guarantors default in the payment of such Redemption Price, interest
on the Securities to be redeemed will cease to accrue on and after the applicable Redemption Date,
whether or not such Securities are presented for payment, and the Holders of such Securities shall
have no further rights with respect to such Securities except for the right to receive the
Redemption Price upon surrender of such Securities. If any Security

21

 

called for redemption shall not be so paid upon surrender thereof for redemption, the
principal, premium, if any, any Additional Amounts, and, to the extent lawful, accrued interest
thereon shall, until paid, bear interest from the Redemption Date at the rate specified pursuant to
Section 2.01 or provided in the Securities or, in the case of Original Issue Discount Securities,
such Securities’ yield to maturity.

SECTION 3.07 Securities Redeemed or Purchased in Part.

          Upon surrender to the Paying Agent of a Security to be redeemed in part, 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 and 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 that is not redeemed.

SECTION 3.08 Purchase of Securities.

          Unless otherwise specified as contemplated by Section 2.01, the Company, any Subsidiary
Guarantor or any Affiliate of the Company or any Subsidiary Guarantor may, subject to applicable
law, at any time purchase or otherwise acquire Securities in the open market or by private
agreement. Any such acquisition shall not operate as or be deemed for any purpose to be a
redemption of the indebtedness represented by such Securities. Any Securities purchased or
acquired by the Company or a Subsidiary Guarantor may be delivered to the Trustee and, upon such
delivery, the indebtedness represented thereby shall be deemed to be satisfied. Section 2.13 shall
apply to all Securities so delivered.

SECTION 3.09 Mandatory and Optional Sinking Funds.

          The minimum amount of any sinking fund payment provided for by the terms of Securities of any
series is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of
such minimum amount provided for by the terms of Securities of any series is herein referred to as
an “optional sinking fund payment.” Unless otherwise provided by the terms of Securities of any
series, the cash amount of any sinking fund payment may be subject to reduction as provided in
Section 3.10. Each sinking fund payment shall be applied to the redemption of Securities of any
series as provided for by the terms of Securities of such series and by this Article III.

SECTION 3.10 Satisfaction of Sinking Fund Payments with Securities.

          The Company or a Subsidiary Guarantor may deliver outstanding Securities of a series (other
than any previously called for redemption) and may apply as a credit Securities of a series that
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 the Securities of such series required to be made pursuant to the terms of such series
of Securities; provided that such Securities have not been previously so credited. Such Securities
shall be received and credited for such purpose by the Trustee at the Redemption

22

 

Price specified in such Securities for redemption through operation of the sinking fund and
the amount of such sinking fund payment shall be reduced accordingly.

SECTION 3.11 Redemption of Securities for Sinking Fund.

          Not less than 45 days prior (unless a shorter period shall be satisfactory to the Trustee) to
each sinking fund payment date for any series of Securities, the Company will deliver to the
Trustee an Officers’ Certificate of the Company specifying the amount of the next ensuing sinking
fund payment for that series pursuant to the terms of that series, 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 delivery of or by crediting Securities of that series pursuant to Section 3.10 and
will also deliver or cause to be delivered to the Trustee any Securities to be so delivered.
Failure of the Company to timely deliver or cause to be delivered such Officers’ Certificate and
Securities specified in this paragraph, if any, shall not constitute a default but shall constitute
the election of the Company (i) that the mandatory sinking fund payment for such series due on the
next succeeding sinking fund payment date shall be paid entirely in cash without the option to
deliver or credit Securities of such series in respect thereof and (ii) that the Company will make
no optional sinking fund payment with respect to such series as provided in this Section.

          If the sinking fund payment or payments (mandatory or optional or both) to be made in cash on
the next succeeding sinking fund payment date plus any unused balance of any preceding sinking fund
payments made in cash shall exceed $100,000 (or the Dollar equivalent thereof based on the
applicable Exchange Rate on the date of original issue of the applicable Securities) or a lesser
sum if the Company shall so request with respect to the Securities of any particular series, such
cash shall be applied on the next succeeding sinking fund payment date to the redemption of
Securities of such series at the sinking fund redemption price together with accrued interest to
the date fixed for redemption. If such amount shall be $100,000 (or the Dollar equivalent thereof
as aforesaid) or less and the Company makes no such request then it shall be carried over until a
sum in excess of $100,000 (or the Dollar equivalent thereof as aforesaid) is available. Not less
than 30 days before 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 3.03 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 3.04. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections 3.05, 3.06 and 3.07.

ARTICLE IV

COVENANTS

SECTION 4.01 Payment of Securities.

          The Company shall pay the principal of, premium (if any) and interest on and any Additional
Amounts with respect to the Securities of each series on the dates and in the manner provided in
the Securities of such series and in this Indenture. Principal, premium, interest and any
Additional Amounts shall be considered paid on the date due if the Paying Agent (other than the
Company, a Subsidiary Guarantor or other Subsidiary) holds on that date money deposited

23

 

by the Company or a Subsidiary Guarantor designated for and sufficient to pay all principal,
premium, interest and any Additional Amounts then due.

          The Company shall pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue principal and premium (if any), at a rate equal to the then applicable
interest rate on the Securities to the extent lawful; and it shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of
interest and any Additional Amount (without regard to any applicable grace period) at the same rate
to the extent lawful.

SECTION 4.02 Maintenance of Office or Agency.

          The Company will maintain in each Place of Payment for any series of Securities an office or
agency (which may be an office of the Trustee, the Registrar or the Paying Agent) where Securities
of that series may be presented for registration of transfer or exchange, where Securities of that
series may be presented for payment and where notices and demands to or upon the Company or a
Subsidiary Guarantor in respect of the Securities of that series and this Indenture may be served.
Unless otherwise designated by the Company by written notice to the Trustee and the Subsidiary
Guarantors, such office or agency shall be the office of the Trustee in The City of New York, which
on the date hereof is located at 1445 Ross Avenue, 2nd Floor, MAC T5303-02J, Dallas, TX 75202. The
Company will give prompt written notice to the Trustee and the Subsidiary Guarantors of the
location, and any change in the location, of such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to furnish the Trustee and
the Subsidiary Guarantors with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the Corporate Trust Office of the Trustee.

          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 4.03 SEC Reports; Financial Statements.

          (a) If the Company is subject to the requirements of Section 13 or 15(d) of the Exchange Act,
the Company shall file with the Trustee, within 15 days after it files the same with the SEC,
copies of the annual reports and the information, documents and other reports (or copies of such
portions of any of the foregoing as the SEC may by rules and regulations prescribe) that the
Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act. If
this Indenture is qualified under the TIA, but not otherwise, the Company shall also comply with
the provisions of TIA § 314(a). Delivery of such reports, information and documents to the Trustee
shall be for informational purposes only, and the Trustee’s receipt thereof shall not constitute
constructive notice of any information contained therein or determinable from information contained
therein, including the Company’s and the Subsidiary

24

 

Guarantors’ compliance with any of their covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers’ Certificates or certificates delivered pursuant to
Section 4.04).

          (b) If the Company is not subject to the requirements of Section 13 or 15(d) of the Exchange
Act, the Company shall furnish to all Holders of Rule 144A Securities and prospective purchasers of
Rule 144A Securities designated by the Holders of Rule 144A Securities, promptly upon their
request, the information required to be delivered pursuant to Rule 144A(d)(4) promulgated under the
Securities Act of 1933, as amended.

days after the end of each fiscal year of the Company, a statement signed by an Officer of the
Company and each Subsidiary Guarantor, respectively, which need not constitute an Officers’
Certificate, complying with TIA § 314(a)(4) and stating that in the course of performance by the
signing Officer of his duties as such Officer of the Company or such Subsidiary Guarantor, as the
case may be, he would normally obtain knowledge of the keeping, observing, performing and
fulfilling by the Company or such Subsidiary Guarantor, as the case may be, of its obligations
under this Indenture, and further stating that to the best of his knowledge the Company or such
Subsidiary Guarantor, as the case may be, has kept, observed, performed and fulfilled each and
every covenant contained in this Indenture and is not in default in the performance or observance
of any of the terms, provisions and conditions hereof (or, if a Default or Event of Default shall
have occurred, describing all such Defaults or Events of Default of which such Officer may have
knowledge and what action the Company or such Subsidiary Guarantor, as the case may be, is taking
or proposes to take with respect thereto).

          (b) The Company or any Subsidiary Guarantor shall, so long as Securities of any series are
outstanding, deliver to the Trustee, forthwith upon any Officer of the Company or such Subsidiary
Guarantor, as the case may be, becoming aware of any Default or Event of Default under this
Indenture, an Officers’ Certificate specifying such Default or Event of Default and what action the
Company or such Subsidiary Guarantor, as the case may be, is taking or proposes to take with
respect thereto.

SECTION 4.05 Corporate Existence.

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

SECTION 4.06 Waiver of Stay, Extension or Usury Laws.

          Each of the Company and the Subsidiary Guarantors covenants (to the extent that it may
lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay or extension law or any usury law or other law
that would prohibit or forgive it from paying all or any portion of the principal of or interest on
the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or
which may affect the covenants or the performance of this Indenture; and (to the extent that it may
lawfully do so) each of the Company and the Subsidiary Guarantors hereby

25

 

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.

SECTION 4.07 Additional Amounts.

          If the Securities of a series expressly provide for the payment of Additional Amounts, the
Company will pay to the Holder of any Security of such series Additional Amounts as expressly
provided therein. Whenever in this Indenture there is mentioned, in any context, the payment of
the principal of or any premium or interest on, or in respect of, any Security of any series or the
net proceeds received from the sale or exchange of any Security of any series, such mention shall
be deemed to include mention of the payment of Additional Amounts provided for in this Section 4.07
to the extent that, in such context, Additional Amounts are, were or would be payable in respect
thereof pursuant to the provisions of this Section 4.07 and express mention of the payment of
Additional Amounts (if applicable) in any provisions hereof shall not be construed as excluding
Additional Amounts in those provisions hereof where such express mention is not made.

Subsidiary Guarantors, or a sale, lease, conveyance, transfer or other disposition of all or
substantially all of the assets of a Subsidiary Guarantor to the Company or of a Subsidiary

Guarantor) formed by such consolidation or into which the Company or such Subsidiary
Guarantor is merged, or to which such sale, lease, conveyance, transfer or other disposition
shall be made (collectively, the “Successor”), expressly assumes by supplemental indenture

DEFAULTS AND REMEDIES

SECTION 6.01 Events of Default.

          Unless either inapplicable to a particular series or specifically deleted or modified in or
pursuant to the supplemental indenture or Board Resolution establishing such series of Securities
or in the form of Security for such series, an “Event of Default,” wherever used herein with
respect to Securities of any series, occurs if:

          (1) the Company defaults in the payment of interest on or any Additional Amounts with
respect to any Security of that series when the same becomes due and payable and such
default continues for a period of 30 days;

          (2) the Company defaults in the payment of (A) the principal of any Security of that
series at its Maturity or (B) premium (if any) on any Security of that series when the same
becomes due and payable;

          (3) the Company defaults in the deposit of any sinking fund payment, when and as due by
the terms of a Security of that series, and such default continues for a period of 30 days;

          (4) the Company, or if any series of Securities outstanding is entitled to the benefits
of a Guarantee, any Subsidiary Guarantor, fails to comply with any of its other covenants or
agreements in, or provisions of, the Securities of such series or this Indenture (other than
an agreement, covenant or provision that has expressly been included in this Indenture
solely for the benefit of one or more series of Securities other

27

 

than that series) which shall not have been remedied within the specified period after
written notice, as specified in the last paragraph of this Section 6.01;

          (5) the Company, or if that series of Securities is entitled to the benefits of a
Guarantee by any Subsidiary Guarantor, any Subsidiary Guarantor, if it is a Significant
Subsidiary, pursuant to or within the meaning of any Bankruptcy Law:

     (A) commences a voluntary case,

     (B) consents to the entry of an order for relief against it in an involuntary
case,

     (C) consents to the appointment of a Bankruptcy Custodian of it or for all or
substantially all of its property, or

     (D) makes a general assignment for the benefit of its creditors;

               (6) a court of competent jurisdiction enters an order or decree under any Bankruptcy
Law that remains unstayed and in effect for 90 days and that:

     (A) is for relief against the Company or any Subsidiary Guarantor with respect
to such series, if it is a Significant Subsidiary, as debtor in an involuntary case,

     (B) appoints a Bankruptcy Custodian of the Company or any Subsidiary Guarantor,
if it is a Significant Subsidiary, or a Bankruptcy Custodian for all or
substantially all of the property of the Company, or any Subsidiary Guarantor with
respect to such series, if it is a Significant Subsidiary, or

     (C) orders the liquidation of the Company or any Subsidiary Guarantor with
respect to such series, if it is a Significant Subsidiary; or

          (7) any Guarantee of any Subsidiary Guarantor that is a Significant Subsidiary with
respect to such series ceases to be in full force and effect with respect to Securities of
that series (except as otherwise provided in this Indenture) or is declared null and void in
a judicial proceeding, or any such Subsidiary Guarantor denies or disaffirms its obligations
under this Indenture or such Guarantee; or

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

          The term “Bankruptcy Custodian” means any receiver, trustee, assignee, liquidator or similar
official under any Bankruptcy Law.

          The Trustee shall not be deemed to know or 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 or Event of Default is received by the

28

 

Trustee at the Corporate Trust Office of the Trustee, and such notice references the
Securities and this Indenture.

          When a Default is cured, it ceases.

          Notwithstanding the foregoing provisions of this Section 6.01, if the principal of, premium
(if any) or interest on or Additional Amounts with respect to any Security is payable in a currency
or currencies (including a composite currency) other than Dollars and such currency or currencies
are not available to the Company or a Subsidiary Guarantor for making payment thereof due to the
imposition of exchange controls or other circumstances beyond the control of the Company or such
Subsidiary Guarantor (a “Conversion Event”), the Company will be entitled to satisfy its
obligations to Holders of the Securities by making such payment in Dollars in an amount equal to
the Dollar equivalent of the amount payable in such other currency, as determined by the Company or
the Subsidiary Guarantor, as the case may be, by reference to the Exchange Rate on the date of such
payment, or, if such rate is not then available, on the basis of the most recently available
Exchange Rate. Notwithstanding the foregoing provisions of this Section 6.01, any payment made
under such circumstances in Dollars where the required payment is in a currency other than Dollars
will not constitute an Event of Default under this Indenture.

          Promptly after the occurrence of a Conversion Event, the Company or a Subsidiary Guarantor
shall give written notice thereof to the Trustee; and the Trustee, promptly after receipt of such
notice, shall give notice thereof in the manner provided in Section 12.02 to the Holders. Promptly
after the making of any payment in Dollars as a result of a Conversion Event, the Company or a
Subsidiary Guarantor, as the case may be, shall give notice in the manner provided in Section 12.02
to the Holders, setting forth the applicable Exchange Rate and describing the calculation of such
payments.

          A Default under clause (4) or (7) of this Section 6.01 is not an Event of Default until the
Trustee notifies the Company and the Subsidiary Guarantors, or the Holders of at least 25% in
principal amount of the then outstanding Securities of the series affected by such Default notify
the Company, the Subsidiary Guarantors and the Trustee, of the Default, and the Company or the
applicable Subsidiary Guarantor, as the case may be, fails to cure the Default within 90 days after
receipt of the notice. The notice must specify the Default, demand that it be remedied and state
that the notice is a “Notice of Default.”

SECTION 6.02 Acceleration.

          If an Event of Default with respect to any Securities of any series at the time outstanding
(other than an Event of Default specified in clause (5) or (6) of Section 6.01) occurs and is
continuing, the Trustee by notice to the Company and the Subsidiary Guarantors, or the Holders of
at least 25% in principal amount of the then outstanding Securities of the series affected by such
Event of Default by notice to the Company, the Subsidiary Guarantors and the Trustee, may declare
the principal of (or, if any such Securities are Original Issue Discount Securities, such portion
of the principal amount as may be specified in the terms of that series) and all accrued and unpaid
interest on all then outstanding Securities of such series to be due and payable. Upon any such
declaration, the amounts due and payable on the Securities shall be due

29

 

and payable immediately. If an Event of Default specified in clause (5) or (6) of Section
6.01 hereof occurs, such amounts shall ipso facto become and be immediately due and payable without
any declaration, notice or other act on the part of the Trustee or any Holder. The Holders of a
majority in principal amount of the then outstanding Securities of the series affected by such
Event of Default by written notice to the Trustee may rescind an acceleration and its consequences
(other than nonpayment of principal of or premium or interest on or any Additional Amounts with
respect to the Securities) if the rescission would not conflict with any judgment or decree and if
all existing Events of Default with respect to Securities of that series have been cured or waived,
except nonpayment of principal, premium, interest or any Additional Amounts that has become due
solely because of the acceleration.

SECTION 6.03 Other Remedies.

          If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy
to collect the payment of principal of, or premium, if any, or interest on the Securities or to
enforce the performance of any provision of the Securities or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any of the Securities or
does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder
in exercising any right or remedy accruing upon an Event of Default shall not impair the right or
remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

SECTION 6.04 Waiver of Defaults.

          Subject to Sections 6.07 and 9.02, the Holders of a majority in principal amount of the then
outstanding Securities of any series by notice to the Trustee may waive an existing or past Default
or Event of Default with respect to such series and its consequences (including waivers obtained in
connection with a tender offer or exchange offer for Securities of such series or a solicitation of
consents in respect of Securities of such series, provided that in each case such offer or
solicitation is made to all Holders of then outstanding Securities of such series), except (1) a
continuing Default or Event of Default in the payment of the principal of, or premium, if any, or
interest on or any Additional Amounts with respect to any Security or (2) a continued Default in
respect of a provision that under Section 9.02 cannot be amended or supplemented without the
consent of each Holder 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 6.05 Control by Majority.

          With respect to Securities of any series, the Holders of a majority in principal amount of the
then outstanding Securities of such series may direct in writing the time, method and place of
conducting any proceeding for any remedy available to the Trustee or exercising any trust or power
conferred on it relating to or arising under an Event of Default described in clause (1), (2), (3)
or (7) of Section 6.01.

30

 

However, the Trustee may refuse to follow any direction that conflicts with
applicable law or this Indenture, that the Trustee determines may be unduly prejudicial to the
rights of other Holders, or that may involve the Trustee in personal liability; provided, however,
that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent
with such direction. Prior to taking any action hereunder, the Trustee shall be entitled to
indemnification satisfactory to it in its sole discretion from Holders directing the Trustee
against all losses and expenses caused by taking or not taking such action.

SECTION 6.06 Limitations on Suits.

          Subject to Section 6.07 hereof, a Holder of a Security of any series may pursue a remedy with
respect to this Indenture or the Securities of such series or any related Guarantees only if:

     (1) the Holder gives to the Trustee written notice of a continuing Event of Default
with respect to such series;

     (2) the Holders of at least 25% in principal amount of the then outstanding Securities
of such series make a written request to the Trustee to pursue the remedy;

     (3) such Holder or Holders offer to the Trustee indemnity satisfactory to the Trustee
against any loss, liability or expense;

     (4) the Trustee does not comply with the request within 60 days after receipt of the
request and the offer of indemnity; and

     (5) during such 60-day period the Holders of a majority in principal amount of the
Securities of that series do not give the Trustee a direction inconsistent with the request.

          A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a
preference or priority over another Holder.

SECTION 6.07 Rights of Holders to Receive Payment.

          Notwithstanding any other provision of this Indenture, the right of any Holder of a Security
to receive payment of principal of and premium, if any, and interest on and any Additional Amounts
with respect to the Security, on or after the respective due dates expressed in the Security, or to
bring suit for the enforcement of any such payment on or after such respective dates, is absolute
and unconditional and shall not be impaired or affected without the consent of the Holder.

SECTION 6.08 Collection Suit by Trustee.

          If an Event of Default specified in clause (1) or (2) of Section 6.01 hereof occurs and is
continuing, the Trustee is authorized to recover judgment in its own name and as trustee of

31

 

an express trust against the Company or a Subsidiary Guarantor for the amount of principal,
premium (if any), interest and any Additional Amounts remaining unpaid on the Securities of the
series affected by the Event of Default, and interest on overdue principal and premium, if any,
and, to the extent lawful, interest on overdue interest, and 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.

SECTION 6.09 Trustee May File Proofs of Claim.

          The Trustee is authorized to file such proofs of claim and other papers or documents and to
take such actions, including participating as a member, voting or otherwise, of any committee of
creditors, as may be necessary or advisable to have the claims of the Trustee (including any claim
for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel) and the Holders allowed in any judicial proceedings relative to the Company or a
Subsidiary Guarantor or their respective creditors or properties and shall be entitled and
empowered to collect, receive and distribute any money or other property payable or deliverable on
any such claims and any Bankruptcy Custodian 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 to 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 7.07. To the extent that
the payment of any such compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel, and any other amounts due the Trustee under Section 7.07 out of the estate in
any such proceeding, shall be denied for any reason, payment of the same shall be secured by a lien
on, and shall be paid out of, any and all distributions, dividends, money, securities and other
properties which the Holders of the Securities may be entitled to receive in such proceeding
whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing
herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or
adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote
in respect of the claim of any Holder in any such proceeding.

SECTION 6.10 Priorities.

          If the Trustee collects any money pursuant to this Article VI, it shall, subject to Article X,
pay out the money in the following order:

     First: to the Trustee for amounts due under Section 7.07;

     Second: to Holders for amounts due and unpaid on the Securities in respect of which or
for the benefit of which such money has been collected, for principal, premium (if any),
interest and any Additional Amounts ratably, without preference or priority of any kind,
according to the amounts due and payable on such Securities for principal, premium (if any),
interest and any Additional Amounts, respectively; and

     Third: to the Company.

32

 

          The Trustee, upon prior written notice to the Company, may fix record dates and payment dates
for any payment to Holders pursuant to this Article VI.

          To the fullest extent allowed under applicable law, if for the purpose of obtaining a judgment
against the Company or a Subsidiary Guarantor in any court it is necessary to convert the sum due
in respect of the principal of, premium (if any) or interest on or Additional Amounts with respect
to the Securities of any series (the “Required Currency”) into a currency in which a judgment will
be rendered (the “Judgment Currency”), the rate of exchange used shall be the rate at which in
accordance with normal banking procedures the Trustee could purchase in The City of New York the
Required Currency with the Judgment Currency on the Business Day in The City of New York next
preceding that on which final judgment is given. None of the Company, any Subsidiary Guarantor or
the Trustee shall be liable for any shortfall nor shall it benefit from any windfall in payments to
Holders of Securities under this Section 6.10 caused by a change in exchange rates between the time
the amount of a judgment against it is calculated as above and the time the Trustee converts the
Judgment Currency into the Required Currency to make payments under this Section 6.10 to Holders of
Securities, but payment of such judgment shall discharge all amounts owed by the Company and the
Subsidiary Guarantors on the claim or claims underlying such judgment.

SECTION 6.11 Undertaking for Costs.

          In any suit for the enforcement of any right or remedy under this Indenture or in any suit
against the Trustee for any action taken or omitted by it as a trustee, a court in its discretion
may require the filing by any party litigant in the suit of an undertaking to pay the costs of the
suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’
fees, against any party litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the
Trustee, a suit by a Holder pursuant to Section 6.07, or a suit by a Holder or Holders of more than
10% in principal amount of the then outstanding Securities of any series.

ARTICLE VII

TRUSTEE

SECTION 7.01 Duties of Trustee.

          (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of
the rights and powers vested in it by this Indenture, and use the same degree of care and skill in
such exercise, as a prudent person would exercise or use under the circumstances in the conduct of
such person’s own affairs.

          (b) Except during the continuance of an Event of Default with respect to the Securities of any
series:

     (1) the Trustee need perform only those duties that are specifically set forth in this
Indenture and no others, and no implied covenants or obligations shall be read into this
Indenture against the Trustee; and

33

 

     (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to
the truth of the statements and the correctness of the opinions expressed therein, upon
certificates or opinions furnished to the Trustee and conforming to the requirements of this
Indenture. However, the Trustee shall examine such certificates and opinions to determine
whether, on their face, they appear to conform to the requirements of this Indenture.

          (c) The Trustee may not be relieved from liabilities for its own negligent action, its own
negligent failure to act or its own willful misconduct, except that:

     (1) this paragraph does not limit the effect of Section 7.01(b);

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

     (3) the Trustee shall not be liable with respect to any action it takes or omits to
take in good faith in accordance with a direction received by it pursuant to Section 6.05.

          (d) Whether or not therein expressly so provided, every provision of this Indenture that in
any way relates to the Trustee is subject to the provisions of this Section 7.01.

          (e) No provision of this Indenture shall require the Trustee to expend or risk its own funds
or incur any liability. The Trustee may refuse to perform any duty or exercise any right or power
unless it receives indemnity satisfactory to it against any loss, liability or expense.

          (f) The Trustee shall not be liable for interest on any money received by it except as the
Trustee may agree in writing with the Company and the Subsidiary Guarantors. Money held in trust
by the Trustee need not be segregated from other funds except to the extent required by law. All
money received by the Trustee shall, until applied as herein provided, be held in trust for the
payment of the principal of, premium (if any) and interest on and Additional Amounts with respect
to the Securities.

SECTION 7.02 Rights of Trustee.

          (a) The Trustee may conclusively rely on any document believed by it to be genuine and to have
been signed or presented by the proper Person. The Trustee need not investigate any fact or matter
stated in the document.

          (b) Before the Trustee acts or refrains from acting, it may require instruction, an Officers’
Certificate or an Opinion of Counsel or both to be provided. The Trustee shall not be liable for
any action it takes or omits to take in good faith in reliance on such instruction, Officers’
Certificate or Opinion of Counsel. The Trustee may consult at the Company’s expense with counsel
of its selection and the written advice of such counsel or any Opinion of Counsel shall be full and
complete authorization and protection in respect of any action taken, suffered or omitted by it
hereunder in good faith and in reliance thereon.

34

 

          (c) The Trustee may act through agents and shall not be responsible for the misconduct or
negligence of any agent appointed with due care.

          (d) The Trustee shall not be liable for any action it takes or omits to take in good faith
which it believes to be authorized or within its rights or powers conferred upon it by this
Indenture.

          (e) Unless otherwise specifically provided in this Indenture, any demand, request, direction
or notice from the Company or any Subsidiary Guarantor shall be sufficient if signed by an Officer
of the Company.

SECTION 7.03 May Hold Securities.

          The Trustee in its individual or any other capacity may become the owner or pledgee of
Securities and may otherwise deal with the Company, any Subsidiary Guarantor or any of their
respective Affiliates with the same rights it would have if it were not Trustee. Any Agent may do
the same with like rights and duties. However, the Trustee is subject to Sections 7.10 and 7.11.

SECTION 7.04 Trustee’s Disclaimer.

          The Trustee makes no representation as to the validity or adequacy of this Indenture or the
Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities
or any money paid to the Company or any Subsidiary Guarantor or upon the Company’s or such
Subsidiary Guarantor’s direction under any provision hereof, it shall not be responsible for the
use or application of any money received by any Paying Agent other than the Trustee and it shall
not be responsible for any statement or recital herein or any statement in the Securities other
than its certificate of authentication.

SECTION 7.05 Notice of Defaults.

          If a Default or Event of Default with respect to the Securities of any series occurs and is
continuing and it is known to the Trustee, the Trustee shall mail to Holders of Securities of such
series a notice of the Default or Event of Default within 90 days after it occurs. Except in the
case of a Default or Event of Default in payment of principal of, premium (if any) and interest on
and Additional Amounts or any sinking fund installment with respect to the Securities of such
series, the Trustee may withhold the notice if and so long as a committee of its Responsible
Officers in good faith determines that withholding the notice is in the interests of Holders of
Securities of such series.

SECTION 7.06 Reports by Trustee to Holders.

          Within
60 days after each _____ of each year after the execution of this Indenture,
the Trustee shall mail to Holders of a series, the Subsidiary Guarantors and the Company a brief
report dated as of such reporting date that complies with TIA § 313(a); provided, however, that if
no event described in TIA § 313(a) has occurred within the twelve months preceding the reporting
date with respect to a series, no report need be transmitted to

35

 

Holders of such series. The Trustee also shall comply with TIA § 313(b). The Trustee shall
also transmit by mail all reports if and as required by TIA §§ 313(c) and 313(d).

          A copy of each report at the time of its mailing to Holders of a series of Securities shall be
filed by the Company or a Subsidiary Guarantor with the SEC and each securities exchange, if any,
on which the Securities of such series are listed. The Company shall notify the Trustee if and
when any series of Securities is listed on any securities exchange.

SECTION 7.07 Compensation and Indemnity.

          The Company agrees to pay to the Trustee for its acceptance of this Indenture and services
hereunder such compensation as the Company and the Trustee shall from time to time agree in
writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee
of an express trust. The Company agrees to reimburse the Trustee upon request for all reasonable
disbursements, advances and expenses incurred by it. Such expenses shall include the reasonable
compensation, disbursements and expenses of the Trustee’s agents and counsel.

          The Company hereby indemnifies the Trustee and any predecessor Trustee against any and all
loss, liability, damage, claim or expense, including taxes (other than taxes based upon, measured
by or determined by the income of the Trustee), incurred by it arising out of or in connection with
the acceptance or administration of its duties under this Indenture, except as set forth in the
next following paragraph. The Trustee shall notify the Company and the Subsidiary Guarantors
promptly of any claim for which it may seek indemnity. The Company shall defend the claim and the
Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company
shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any
settlement made without its consent.

          The Company shall not be obligated to reimburse any expense or indemnify against any loss or
liability incurred by the Trustee through the Trustee’s negligence or bad faith.

          To secure the payment obligations of the Company in this Section 7.07, the Trustee shall have
a lien prior to the Securities on all money or property held or collected by the Trustee, except
that held in trust to pay principal of, premium (if any) and interest on and any Additional Amounts
with respect to Securities of any series. Such lien and the Company’s obligations under this
Section 7.07 shall survive the satisfaction and discharge of this Indenture.

          When the Trustee incurs expenses or renders services after an Event of Default specified in
Section 6.01(5) or (6) occurs, the expenses and the compensation for the services are intended to
constitute expenses of administration under any Bankruptcy Law.

SECTION 7.08 Replacement of Trustee.

          A resignation or removal of the Trustee and appointment of a successor Trustee shall become
effective only upon the successor Trustee’s acceptance of appointment as provided in this Section
7.08.

          The Trustee may resign and be discharged at any time with respect to the Securities of one or
more series by so notifying the Company and the Subsidiary Guarantors.

36

 

The Holders of a majority in principal amount of the then outstanding Securities of any series
may remove the Trustee with respect to the Securities of such series by so notifying the Trustee,
the Company and the Subsidiary Guarantors. The Company may remove the Trustee if:

     (1) the Trustee fails to comply with Section 7.10;

     (2) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is
entered with respect to the Trustee under any Bankruptcy Law;

     (3) a Bankruptcy Custodian or public officer takes charge of the Trustee or its
property; or

     (4) the Trustee otherwise becomes incapable of acting.

          If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any
reason, with respect to the Securities of one or more series, the Company 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). Within one year after the successor Trustee with respect
to the Securities of any series takes office, the Holders of a majority in principal amount of the
Securities of such series then outstanding may appoint a successor Trustee to replace the successor
Trustee appointed by the Company.

          If a successor Trustee with respect to the Securities of any series does not take office
within 30 days after the retiring or removed Trustee resigns or is removed, the retiring or removed
Trustee, the Company, any Subsidiary Guarantor or the Holders of at least 10% in principal amount
of the then outstanding Securities of such series may petition any court of competent jurisdiction
for the appointment of a successor Trustee with respect to the Securities of such series.

          If the Trustee with respect to the Securities of a series fails to comply with Section 7.10,
any Holder of Securities of such series may petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee with respect to the Securities of
such series.

          In case of the appointment of a successor Trustee with respect to all Securities, each such
successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee, to
the Company and to the Subsidiary Guarantors. Thereupon the resignation or removal of the retiring
Trustee shall become effective, and the successor Trustee shall have all the rights, powers and
duties of the retiring Trustee under this Indenture. The successor Trustee shall mail a notice of
its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as
Trustee to the successor Trustee, subject to the lien provided for in Section 7.07.

          In case of the appointment of a successor Trustee with respect to the Securities of one or
more (but not all) series, the Company, the Subsidiary Guarantors, the retiring Trustee and each
successor Trustee with respect to the Securities of one or more (but not all) series shall

37

 

execute and deliver an indenture supplemental hereto in which each successor Trustee shall
accept such appointment and that (1) shall confer to each successor Trustee all the rights, powers
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 confirm that all the rights, powers 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. Nothing herein or in such
supplemental indenture shall constitute such Trustees co-trustees of the same trust, and 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. 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 shall have all the rights, powers
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. On request of the Company or any successor
Trustee, such retiring Trustee shall transfer to such successor Trustee all property held by such
retiring Trustee as Trustee with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates.

          Notwithstanding replacement of the Trustee or Trustees pursuant to this Section 7.08, the
obligations of the Company under Section 7.07 shall continue for the benefit of the retiring
Trustee or Trustees.

SECTION 7.09 Successor Trustee by Merger, etc.

          Subject to Section 7.10, if the Trustee consolidates, merges or converts into, or transfers
all or substantially all of its corporate trust business to, another corporation, the successor
corporation without any further act shall be the successor Trustee; provided, however, that in the
case of a transfer of all or substantially all of its corporate trust business to another
corporation, the transferee corporation expressly assumes all of the Trustee’s liabilities
hereunder.

          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; and in case at that time any
of the Securities shall not have been authenticated, any successor to the Trustee may authenticate
such Securities either in the name of any predecessor hereunder or in the name of the successor to
the Trustee; and in all such cases such certificates shall have the full force which it is anywhere
in the Securities or in this Indenture provided that the certificate of the Trustee shall have.

SECTION 7.10 Eligibility; Disqualification.

          There shall at all times be a Trustee hereunder which shall be a corporation or banking or
trust company or association organized and doing business under the laws of the United States, any
State thereof or the District of Columbia and authorized under such laws to

38

 

exercise corporate trust power, shall be subject to supervision or examination by Federal or
State (or the District of Columbia) authority and shall have, or be a subsidiary of a bank or bank
holding company having, a combined capital and surplus of at least $50 million as set forth in its
most recent published annual report of condition.

          The Indenture shall always have a Trustee who satisfies the requirements of TIA §§ 310(a)(1),
310(a)(2) and 310(a)(5). The Trustee is subject to and shall comply with the provisions of TIA
§ 310(b) during the period of time required by this Indenture. Nothing in this Indenture shall
prevent the Trustee from filing with the SEC the application referred to in the penultimate
paragraph of TIA § 310(b).

			
	SECTION 7.11	 	Preferential Collection of Claims Against the Company or a Subsidiary Guarantor.

          The Trustee is subject to and shall comply with the provisions of TIA § 311(a), excluding any
creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be
subject to TIA § 311(a) to the extent indicated therein.

ARTICLE VIII

DISCHARGE OF INDENTURE

			
	SECTION 8.01	 	Termination of the Company’s and the Subsidiary Guarantors’ Obligations.

          (a) This Indenture shall cease to be of further effect with respect to the Securities of a
series (except that the Company’s obligations under Section 7.07, the Trustee’s and Paying Agent’s
obligations under Section 8.03 and the rights, powers, protections and privileges accorded the
Trustee under Article VII shall survive), and the Trustee, on demand of the Company, shall execute
proper instruments acknowledging the satisfaction and discharge of this Indenture with respect to
the Securities of such series, when:

     (1) either:

     (A) all outstanding Securities of such series theretofore authenticated and
issued (other than destroyed, lost or stolen Securities that have been replaced or
paid) have been delivered to the Trustee for cancellation; or

     (B) all outstanding Securities of such series not theretofore delivered to the
Trustee for cancellation:

	 	(i)	 	have become due and payable, or
	 
	 	(ii)	 	will become due and payable at
their Stated Maturity within one year, or
	 
	 	(iii)	 	are to be called for redemption
within one year under arrangements satisfactory to the Trustee
for the giving of

39

 

	 	 	 	notice of redemption by the Trustee in the name, and at the
expense, of the Company,

and, in the case of clause (i), (ii) or (iii) above, the Company or a Subsidiary
Guarantor has irrevocably deposited or caused to be deposited with the Trustee as
funds (immediately available to the Holders in the case of clause (i)) in trust for
such purpose (x) cash in an amount, or (y) Government Obligations, maturing as to
principal and interest at such times and in such amounts as will ensure the
availability of cash in an amount or (z) a combination thereof, which will be
sufficient, in the opinion (in the case of clauses (y) and (z)) of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, to pay and discharge the entire
indebtedness on the Securities of such series for principal and interest to the date
of such deposit (in the case of Securities which have become due and payable) or for
principal, premium, if any, and interest to the Stated Maturity or Redemption Date,
as the case may be; or

          (C) the Company and the Subsidiary Guarantors have properly fulfilled such
other means of satisfaction and discharge as is specified, as contemplated by
Section 2.01, to be applicable to the Securities of such series;

     (2) the Company or a Subsidiary Guarantor has paid or caused to be paid all other sums
payable by them hereunder with respect to the Securities of such series; and

     (3) the Company has delivered to the Trustee an Officers’ Certificate stating that all
conditions precedent to satisfaction and discharge of this Indenture with respect to the
Securities of such series have been complied with, together with an Opinion of Counsel to
the same effect.

          (b) Unless this Section 8.01(b) is specified as not being applicable to Securities of a series
as contemplated by Section 2.01, the Company may, at its option, terminate certain of its and the
Subsidiary Guarantors’ respective obligations under this Indenture (“covenant defeasance”) with
respect to the Securities of a series if:

     (1) the Company or a Subsidiary Guarantor has irrevocably deposited or caused to be
irrevocably deposited with the Trustee 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 Securities of such series, (i) money in the currency in which payment of
the Securities of such series is to be made in an amount, or (ii) Government Obligations
with respect to such series, maturing as to principal and interest at such times and in such
amounts as will ensure the availability of money in the currency in which payment of the
Securities of such series is to be made in an amount or (iii) a combination thereof, that is
sufficient, in the opinion (in the case of clauses (ii) and (iii)) of a nationally
recognized firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee, to pay the principal of and premium (if any) and interest
on all Securities of such series on each date that such principal, premium (if any) or
interest is due and payable and (at the Stated Maturity thereof or

40

 

upon redemption as provided in Section 8.01(e)) to pay all other sums payable by it
hereunder; provided that the Trustee shall have been irrevocably instructed to apply such
money and/or the proceeds of such Government Obligations to the payment of said principal,
premium (if any) and interest with respect to the Securities of such series as the same
shall become due;

     (2) the Company has delivered to the Trustee an Officers’ Certificate stating that all
conditions precedent to satisfaction and discharge of this Indenture with respect to the
Securities of such series have been complied with, and an Opinion of Counsel to the same
effect;

     (3) no Default or Event of Default with respect to the Securities of such series shall
have occurred and be continuing on the date of such deposit;

     (4) the Company shall have delivered to the Trustee an Opinion of Counsel from a
nationally recognized counsel acceptable to the Trustee or a tax ruling to the effect that
the Holders will not recognize income, gain or loss for U.S. Federal income tax purposes as
a result of the Company’s exercise of its option under this Section 8.01(b) and will be
subject to U.S. Federal income tax on the same amount and in the same manner and at the same
times as would have been the case if such option had not been exercised;

     (5) the Company and the Subsidiary Guarantors have complied with any additional
conditions specified pursuant to Section 2.01 to be applicable to the discharge of
Securities of such series pursuant to this Section 8.01; and

     (6) such deposit and discharge shall not cause the Trustee to have a conflicting
interest as defined in TIA § 310(b).

          In such event, this Indenture shall cease to be of further effect (except as set forth in this
paragraph), and the Trustee, on demand of the Company, shall execute proper instruments
acknowledging satisfaction and discharge under this Indenture. However, the Company’s and the
Subsidiary Guarantors’ respective obligations in Sections 2.05, 2.06, 2.07, 2.08, 2.09, 4.01, 4.02,
7.07, 7.08 and 8.04, the Trustee’s and Paying Agent’s obligations in Section 8.03 and the rights,
powers, protections and privileges accorded the Trustee under Article VII shall survive until all
Securities of such series are no longer outstanding. Thereafter, only the Company’s obligations in
Section 7.07 and the Trustee’s and Paying Agent’s obligations in Section 8.03 shall survive with
respect to Securities of such series.

          After such irrevocable deposit made pursuant to this Section 8.01(b) and satisfaction of the
other conditions set forth herein, the Trustee upon request shall acknowledge in writing the
discharge of the Company’s and the Subsidiary Guarantors’ obligations under this Indenture with
respect to the Securities of such series except for those surviving obligations specified above.

          In order to have money available on a payment date to pay principal of or premium (if any) or
interest on the Securities, the Government Obligations shall be payable as to

41

 

principal or interest on or before such payment date in such amounts as will provide the
necessary money. Government Obligations shall not be callable at the issuer’s option.

          (c) If the Company and the Subsidiary Guarantors have previously complied or is concurrently
complying with Section 8.01(b) (other than any additional conditions specified pursuant to
Section 2.01 that are expressly applicable only to covenant defeasance) with respect to Securities
of a series, then, unless this Section 8.01(c) is specified as not being applicable to Securities
of such series as contemplated by Section 2.01, the Company may elect that its and the Subsidiary
Guarantors’ respective obligations to make payments with respect to Securities of such series be
discharged (“legal defeasance”), if:

     (1) no Default or Event of Default under clauses (5) and (6) of Section 6.01 hereof
shall have occurred at any time during the period ending on the 91st day after the date of
deposit contemplated by Section 8.01(b) (it being understood that this condition shall not
be deemed satisfied until the expiration of such period);

     (2) unless otherwise specified with respect to Securities of such series as
contemplated by Section 2.01, the Company has delivered to the Trustee an Opinion of Counsel
from a nationally recognized counsel acceptable to the Trustee to the effect referred to in
Section 8.01(b)(4) with respect to such legal defeasance, which opinion is based on (i) a
private ruling of the Internal Revenue Service addressed to the Company, (ii) a published
ruling of the Internal Revenue Service pertaining to a comparable form of transaction or
(iii) a change in the applicable federal income tax law (including regulations) after the
date of this Indenture;

     (3) the Company and the Subsidiary Guarantors have complied with any other conditions
specified pursuant to Section 2.01 to be applicable to the legal defeasance of Securities of
such series pursuant to this Section 8.01(c); and

     (4) the Company has delivered to the Trustee a Company Request requesting such legal
defeasance of the Securities of such series and an Officers’ Certificate stating that all
conditions precedent with respect to such legal defeasance of the Securities of such series
have been complied with, together with an Opinion of Counsel to the same effect.

          In such event, the Company and the Subsidiary Guarantors will be discharged from its
obligations under this Indenture and the Securities of such series to pay principal of, premium (if
any) and interest on and any Additional Amounts with respect to Securities of such series, the
Company’s and the Subsidiary Guarantors’ respective obligations under Sections 4.01, 4.02 and 10.1
shall terminate with respect to such Securities, and the entire indebtedness of the Company
evidenced by such Securities and of the Subsidiary Guarantors evidenced by the related Guarantee
shall be deemed paid and discharged.

          (d) If and to the extent additional or alternative means of satisfaction, discharge or
defeasance of Securities of a series are specified to be applicable to such series as contemplated
by Section 2.01, each of the Company and the Subsidiary Guarantors may terminate any or all of its
obligations under this Indenture with respect to Securities of a series

42

 

and any or all of its obligations under the Securities of such series if it fulfills such
other means of satisfaction and discharge as may be so specified, as contemplated by Section 2.01,
to be applicable to the Securities of such series.

          (e) If Securities of any series subject to subsections (a), (b), (c) or (d) of this Section
8.01 are to be redeemed prior to their Stated Maturity, whether pursuant to any optional redemption
provisions or in accordance with any mandatory or optional sinking fund provisions, the terms of
the applicable trust arrangement shall provide for such redemption, and the Company shall make such
arrangements as are reasonably satisfactory to the Trustee for the giving of notice of redemption
by the Trustee in the name, and at the expense, of the Company.

SECTION 8.02 Application of Trust Money.

          The Trustee or a trustee satisfactory to the Trustee and the Company shall hold in trust money
or Government Obligations deposited with it pursuant to Section 8.01 hereof. It shall apply the
deposited money and the money from Government Obligations through the Paying Agent and in
accordance with this Indenture to the payment of principal of, premium (if any) and interest on and
any Additional Amounts with respect to the Securities of the series with respect to which the
deposit was made. Money and securities held in trust are not subject to Article X.

SECTION 8.03 Repayment to Company.

          The Trustee and the Paying Agent shall promptly pay to the Company or any Subsidiary Guarantor
any excess money or Government Obligations (or proceeds therefrom) held by them at any time upon
the written request of the Company.

          Subject to the requirements of any applicable abandoned property laws, the Trustee and the
Paying Agent shall pay to the Company upon written request any money held by them for the payment
of principal, premium (if any), interest or any Additional Amounts that remain unclaimed for two
years after the date upon which such payment shall have become due. After payment to the Company,
Holders entitled to the money must look to the Company for payment as general creditors unless an
applicable abandoned property law designates another Person, and all liability of the Trustee and
the Paying Agent with respect to such money shall cease.

SECTION 8.04 Reinstatement.

          If the Trustee or the Paying Agent is unable to apply any money or Government Obligations
deposited with respect to Securities of any series in accordance with Section 8.01 by reason of any
legal proceeding or by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the obligations of the Company
and the Subsidiary Guarantors under this Indenture with respect to the Securities of such series
and under the Securities of such series shall be revived and reinstated as though no deposit had
occurred pursuant to Section 8.01 until such time as the Trustee or the Paying Agent is permitted
to apply all such money or Government Obligations in accordance with Section 8.01; provided,
however, that if the Company or any Subsidiary Guarantor has made any payment of principal of,
premium (if any) or interest on or any

43

 

Additional Amounts with respect to any Securities because of the reinstatement of its
obligations, the Company or such Subsidiary Guarantor, as the case may be, shall be subrogated to
the rights of the Holders of such Securities to receive such payment from the money or Government
Obligations held by the Trustee or the Paying Agent.

ARTICLE IX

SECTION 9.01 Without Consent of Holders.

          The Company, the Subsidiary Guarantors and the Trustee may amend or supplement this Indenture

being included solely for the benefit of such series), or to surrender any right or power
herein conferred upon the Company or any Subsidiary Guarantor;

     (7) to add any additional Events of Default with respect to all or any series of the
Securities (and, if any Event of Default is applicable to less than all series of
Securities, specifying the series to which such Event of Default is applicable);

     (8) to change or eliminate any of the provisions of this Indenture; provided that any
such change or elimination shall become effective only when there is no outstanding Security
of any series created prior to the execution of such amendment or supplemental indenture
that is adversely affected in any material respect by such change in or elimination of such
provision; provided, further, that any change made solely to conform the provisions of this
Indenture to the description of any Security in a prospectus
supplement pursuant to which such Securities were offered and sold will not be deemed
to adversely affect any Security of any series in any material respect;

44

 

     (9) to establish the form or terms of Securities of any series as permitted by Section
2.01;

     (10) to supplement any of the provisions of this Indenture to such extent as shall be

the interest of the Holders of Securities of such series or any other series of Securities
in any material respect; or

     (11) to evidence and provide for the acceptance of appointment hereunder by a successor
Trustee with respect to the Securities of one or more series and to add to or change any of
the provisions of this Indenture as shall be necessary to provide for or facilitate the
administration of the trusts hereunder by more than one Trustee, pursuant to the
requirements of Section 7.08.

          Upon the request of the Company, accompanied by a Board Resolution, and upon receipt by the
Trustee of the documents described in Section 9.06, the Trustee shall, subject to Section 9.06,
join with the Company and the Subsidiary Guarantors in the execution of any supplemental indenture
authorized or permitted by the terms of this Indenture and make any further appropriate agreements
and stipulations that may be therein contained.

SECTION 9.02 With Consent of Holders.

          Except as provided below in this Section 9.02, the Company, the Subsidiary Guarantors and the
Trustee may amend or supplement this Indenture with the written consent (including consents
obtained in connection with a tender offer or exchange offer for Securities of any one or more
series or all series or a solicitation of consents in respect of Securities of any one or more
series or all series, provided that in each case such offer or solicitation is made to all Holders
of then outstanding Securities of each such series (but the terms of such offer or solicitation may
vary from series to series)) of the Holders of at least a majority in principal amount of the then
outstanding Securities of each series affected by such amendment or supplement.

          Upon the request of the Company, accompanied by a Board Resolution, and upon the filing with
the Trustee of evidence of the consent of the Holders as aforesaid, and upon receipt by the Trustee
of the documents described in Section 9.06, the Trustee shall, subject to Section 9.06, join with
the Company and the Subsidiary Guarantors in the execution of such amendment or supplemental
indenture.

          It shall not be necessary for the consent of the Holders under this Section 9.02 to approve
the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if
such consent approves the substance thereof.

          The Holders of a majority in principal amount of the then outstanding Securities of one or
more series may waive compliance in a particular instance by the Company or any Subsidiary
Guarantor with any provision of this Indenture with respect to Securities of such series (including
waivers obtained in connection with a tender offer or exchange offer for Securities of such series
or a solicitation of consents in respect of Securities of such series,

45

 

provided that in each case such offer or solicitation is made to all Holders of then
outstanding Securities of such series (but the terms of such offer or solicitation may vary from
series to series)).

          However, without the consent of each Holder affected, an amendment, supplement or waiver under
this Section 9.02 may not:

     (1) reduce the amount of Securities whose Holders must consent to an amendment,
supplement or waiver;

     (2) reduce the rate of or change the time for payment of interest, including default
interest, on any Security;

     (3) reduce the principal of, any premium on or any mandatory sinking fund payment with
respect to, or change the Stated Maturity of, any Security or reduce the amount of the
principal of an Original Issue Discount Security that would be due and payable upon a
declaration of acceleration of the Maturity thereof pursuant to Section 6.02;

     (4) reduce the premium, if any, payable upon the redemption of any Security or change
the time at which any Security may or shall be redeemed;

     (5) change any obligation of the Company or any Subsidiary Guarantor to pay Additional
Amounts with respect to any Security;

     (6) change the coin or currency or currencies (including composite currencies) in which
any Security or any premium, interest or Additional Amounts with respect thereto are
payable;

     (7) impair the right to institute suit for the enforcement of any payment of principal
of, premium (if any) or interest on or any Additional Amounts with respect to any Security
pursuant to Sections 6.07 and 6.08, except as limited by Section 6.06;

     (8) make any change in the percentage of principal amount of Securities necessary to
waive compliance with certain provisions of this Indenture pursuant to Section 6.04 or 6.07
or make any change in this sentence of Section 9.02;

     (9) modify the provisions of this Indenture with respect to the subordination of any
Security in a manner adverse to the Holder thereof;

     (10) except as provided in Section 11.04, release any Subsidiary Guarantor or modify
the related Guarantee in any manner materially adverse to the Holders; or

     (11) waive a continuing Default or Event of Default in the payment of principal of,
premium (if any) or interest on or Additional Amounts with respect to the Securities.

46

 

          An amendment under this Section 9.02 may not make any change that adversely affects the rights
under Article X of any holder of an issue of Senior Debt unless the holders of the issue pursuant
to its terms consent to the change.

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

          The right of any Holder to participate in any consent required or sought pursuant to any
provision of this Indenture (and the obligation of the Company or any Subsidiary Guarantor to
obtain any such consent otherwise required from such Holder) may be subject to the requirement that
such Holder shall have been the Holder of record of any Securities with respect to which such
consent is required or sought as of a date identified by the Company or such Subsidiary Guarantor
in a notice furnished to Holders in accordance with the terms of this Indenture.

          After an amendment, supplement or waiver under this Section 9.02 becomes effective, the
Company shall mail to the Holders of each Security affected thereby a notice briefly describing the
amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect
therein, shall not, however, in any way impair or affect the validity of any such amendment,
supplement or waiver.

SECTION 9.03 Compliance with Trust Indenture Act.

          Every amendment or supplement to this Indenture or the Securities shall comply in form and
substance with the TIA as then in effect.

SECTION 9.04 Revocation and Effect of Consents.

          Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a
continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security
that evidences the same debt as the consenting Holder’s Security, even if notation of the consent
is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent
as to his or her Security or portion of a Security if the Trustee receives written notice of
revocation before a date and time therefor identified by the Company or any Subsidiary Guarantor in
a notice furnished to such Holder in accordance with the terms of this Indenture or, if no such
date and time shall be identified, the date the amendment, supplement or waiver becomes effective.
An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter
binds every Holder.

          The Company or any Subsidiary Guarantor may, but shall not be obligated to, fix a record date
(which need not comply with TIA § 316(c)) for the purpose of determining the Holders entitled to
consent to any amendment, supplement or waiver or to take any other action under this Indenture.
If a record date is fixed, then notwithstanding the provisions of the immediately preceding
paragraph, those Persons who were Holders at such record date (or their duly designated proxies),
and only those Persons, shall be entitled to consent to such amendment,

47

 

supplement or waiver or to revoke any consent previously given, whether or not such Persons
continue to be Holders after such record date. No consent shall be valid or effective for more
than 90 days after such record date unless consents from Holders of the principal amount of
Securities required hereunder for such amendment or waiver to be effective shall have also been
given and not revoked within such 90-day period.

          After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless
it is of the type described in any of clauses (1) through (9) of Section 9.02 hereof. In such
case, the amendment, supplement or waiver shall bind each Holder who has consented to it and every
subsequent Holder that evidences the same debt as the consenting Holder’s Security.

SECTION 9.05 Notation on or Exchange of Securities.

          If an amendment or supplement changes the terms of an outstanding Security, the Company may
require the Holder of the Security to deliver it to the Trustee. The Trustee may place an
appropriate notation on the Security at the request of the Company regarding the changed terms and
return it to the Holder. Alternatively, if the Company so determines, the Company in exchange for
the Security shall issue and the Trustee shall authenticate a new Security that reflects the
changed terms. Failure to make the appropriate notation or to issue a new Security shall not
affect the validity of such amendment or supplement.

          Securities of any series authenticated and delivered after the execution of any amendment or
supplement 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 amendment or supplement.

SECTION 9.06 Trustee to Sign Amendments, etc.

          The Trustee shall sign any amendment or supplement authorized pursuant to this Article if the
amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of
the Trustee. If it does, the Trustee may, but need not, sign it. In signing or refusing to sign
such amendment or supplement, the Trustee shall be entitled to receive, and, shall be fully
protected in relying upon in good faith, an Officers’ Certificate and an Opinion of Counsel
provided at the expense of the Company or a Subsidiary Guarantor as conclusive evidence that such
amendment or supplement is authorized or permitted by this Indenture, that it is not inconsistent
herewith, and that it will be valid and binding upon the Company in accordance with its terms.

the Subsidiary Guarantors, as the case may be, shall be received by the Trustee, the Paying Agent
or the Holders of Securities of any series and any related Guarantees at a time when such payment
or distribution was prohibited by the provisions of this Section 10.02, then, unless such payment

	SECTION 10.03	 	Securities and Guarantees Subordinated to Prior Payment of All Senior Debt on
Dissolution, Liquidation or Reorganization.

          Upon any distribution of assets of the Company or the Subsidiary Guarantors, as the case may
be, or upon any dissolution, winding up, total or partial liquidation or reorganization of the
Company or the Subsidiary Guarantors, as the case may be, whether voluntary or involuntary, in
bankruptcy, insolvency, receivership or similar proceeding or upon assignment for the benefit of
creditors:

     (1) the holders of all Senior Debt of the Company shall first be entitled to receive
payments in full before the Holders of Securities of any series and any related Guarantees
are entitled to receive any payment on account of the principal of, premium (if any) or
interest on or any Additional Amounts with respect to Securities of such series and any
related Guarantees;

     (2) any payment or distribution of assets of the Company or the Subsidiary Guarantors,
as the case may be, of any kind or character, whether in cash, property or securities, to
which the Holders of Securities of any series and any related Guarantees, or the Trustee on
behalf of such Holders would be entitled, except for the provisions of this Article X, shall
be paid by the liquidating trustee or agent or other Person making such a payment or
distribution directly to the holders of such Senior Debt or their representative, ratably
according to the respective amounts of Senior Debt held or represented by each, to the
extent necessary to make payment in full of all such Senior Debt remaining unpaid after
giving effect to all concurrent payments and distributions to the holders of such Senior
Debt; and

     (3) in the event that, notwithstanding the foregoing, any payment or distribution of
assets of the Company or the Subsidiary Guarantors, as the case may be, of any kind or
character, whether in cash, property or securities, shall be received by the Trustee or the
Holders of Securities of any series and any related Guarantees or any Paying Agent (or, if
the Company, the Subsidiary Guarantor or any other Subsidiary is acting as the Paying Agent,
money for any such payment or distribution shall be segregated or held in trust) on account
of the principal of, premium (if any) or interest on or any Additional Amounts with respect
to the Securities of such series and any related Guarantees before all Senior Debt of the
Company is paid in full, such payment or distribution (subject to the provisions of Section
10.07) shall be received and held in trust by the Trustee or such Holder or Paying Agent for
the benefit of the holders of such Senior Debt, or their respective representatives, ratably
according to the respective amounts of such Senior Debt held or represented by each, to the
extent necessary to make payment as provided herein of all such Senior Debt remaining unpaid
after giving effect to all concurrent payments and distributions and all provisions therefor
to or for the holders of such Senior Debt, but only to the extent that as to any holder of
such Senior Debt, as promptly as practical following notice from the Trustee to the holders
of such Senior Debt that such prohibited payment has been received by the Trustee, Holder(s)
or Paying Agent (or has been segregated as provided above), such holder (or a representative
therefor) notifies the Trustee of the amounts then due and owing on such

50

 

Senior Debt, if any, held by such holder and only the amounts specified in such notices
to the Trustee shall be paid to the holders of such Senior Debt.

SECTION 10.04 Subrogation to Rights of Holders of Senior Debt.

          Subject to the payment in full of all Senior Debt of the Company as provided herein, the
Holders of the Securities of any series and any related Guarantees shall be subrogated (to the
extent of the payments or distributions made to the holders of such Senior Debt pursuant to the
provisions of this Article X) to the rights of the holders of such Senior Debt to receive payments
or distributions of assets of the Company or the Subsidiary Guarantors, as the case may be,
applicable to the Senior Debt until all amounts owing on the Securities of such series and any
related Guarantees shall be paid in full. For the purpose of such subrogation, no such payments or
distributions to the holders of such Senior Debt by the Company or the Subsidiary Guarantors, as
the case may be, or by or on behalf of the Holders of the Securities of such series and any related
Guarantees by virtue of this Article X, which otherwise would have been made to such Holders shall,
as between the Company or the Subsidiary Guarantors, as the case may be, and such Holders, be
deemed to be payment by the Company or the Subsidiary Guarantors, as the case may be, or on account
of such Senior Debt, it being understood that the provisions of this Article X are and are intended
solely for the purpose of defining the relative rights of the Holders of the Securities of a series
and any related Guarantees, on the one hand, and the holders of such Senior Debt, on the other
hand.

          If any payment or distribution to which the Holders of the Securities and any related
Guarantees would otherwise have been entitled but for the provisions of this Article X shall have
been applied, pursuant to the provisions of this Article X, to the payment of amounts payable under
Senior Debt, then such Holders shall be entitled to receive from the holders of such Senior Debt
any payments or distributions received by such holders of Senior Debt in excess of the amount
sufficient to pay all amounts payable under or in respect of such Senior Debt in full.

			
	SECTION 10.05	 	Obligations of the Company and the Subsidiary Guarantors Unconditional.

          Nothing contained in this Article X or elsewhere in this Indenture or in the Securities is
intended to or shall impair, as between the Company or the Subsidiary Guarantors, as the case may
be, and the Holders of the Securities of any series and any related Guarantees, the obligation of
the Company or the Subsidiary Guarantors, as the case may be, which is absolute and unconditional,
to pay to such Holders the principal of such series, premium (if any) and interest on and any
Additional Amounts with respect to the Securities of such series and any related Guarantees of such
series as and when the same shall become due and payable in accordance with their terms, or is
intended to or shall affect the relative rights of such Holders and creditors of the Company or the
Subsidiary Guarantors, as the case may be, other than the holders of the Senior Debt, nor shall
anything herein or therein prevent the Trustee or any Holder from exercising all remedies otherwise
permitted by applicable law upon default under this Indenture, subject to the rights, if any, under
this Article X, of the holders of Senior Debt in respect of cash, property or securities of the
Company or the Subsidiary Guarantors, as the case may be, received upon the exercise of any such
remedy. Notwithstanding anything to the

51

 

contrary in this Article X or elsewhere in this Indenture or in the Securities, upon any
distribution of assets of the Company or the Subsidiary Guarantors, as the case may be, referred to
in this Article X, the Trustee, subject to the provisions of Sections 7.01 and 7.02, and the
Holders of the Securities and any related Guarantee shall be entitled to rely upon any order or
decree made by any court of competent jurisdiction in which such dissolution, winding up,
liquidation or reorganization proceedings are pending, or a certificate of the liquidating trustee
or agent or other Person making any distribution to the Trustee or to such Holders for the purpose
of ascertaining the Persons entitled to participate in such distribution, the holders of the Senior
Debt and other Debt of the Company or any Subsidiary Guarantors, as the case may be, the amount
thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article X so long as such court has been apprised of the provisions
of, or the order, decree or certificate makes reference to, the provisions of this Article X.

SECTION 10.06 Trustee Entitled to Assume Payments Not Prohibited in Absence of Notice.

          The Trustee shall not at any time be charged with knowledge of the existence of any facts that
would prohibit the making of any payment to or by the Trustee unless and until a Responsible
Officer of the Trustee or any Paying Agent shall have received, no later than two Business Days
prior to such payment, written notice thereof from the Company or the Subsidiary Guarantor, as the
case may be, or from one or more holders of Senior Debt or from any representative thereof and,
prior to the receipt of any such written notice, the Trustee, subject to the provisions of Sections
7.01 and 7.02, shall be entitled in all respects conclusively to assume that no such fact exists.

SECTION 10.07 Application by Trustee of Amounts Deposited with It.

          Amounts deposited in trust with the Trustee pursuant to and in accordance with Article VIII
shall be for the sole benefit of Holders of Securities of the series for the benefit of which such
amounts were deposited, and, to the extent allocated for the payment of Securities and any related
Guarantees of such series, shall not be subject to the subordination provisions of this Article X.
Otherwise, any deposit of assets with the Trustee or the Paying Agent (whether or not in trust) for
the payment of principal of, premium (if any) or interest on or any Additional Amounts with respect
to any Securities of such series and any related Guarantees shall be subject to the provisions of
Sections 10.01, 10.02, 10.03 and 10.04; provided that if prior to two Business Days preceding the
date on which by the terms of this Indenture any such assets may become distributable for any
purpose (including, without limitation, the payment of either principal of, premium (if any) or
interest on or any Additional Amounts with respect to any Security and any related Guarantees), a
Responsible Officer of the Trustee or such Paying Agent shall not have received with respect to
such assets the written notice provided for in Section 10.06, then the Trustee or such Paying Agent
shall have full power and authority to receive such assets and to apply the same to the purpose for
which they were received, and shall not be affected by any notice to the contrary that may be
received by it on or after such date; and provided further that nothing contained in this Article X
shall prevent the Company or the Subsidiary Guarantors, as the case may be, from making, or the
Trustee from receiving or applying, any payment in connection with the redemption of Securities of
a series if the first publication of notice of such redemption (whether by mail or otherwise in
accordance with this

52

 

Indenture) has been made, and the Trustee has received such payment from the Company or the
Subsidiary Guarantors, as the case may be, prior to the occurrence of any of the contingencies
specified in Section 10.02 or 10.03.

			
	SECTION 10.08	 	Subordination Rights Not Impaired by Acts or Omissions of the Company, the Subsidiary
Guarantors or Holders of Senior Debt.

          No right of any present or future holders of any Senior Debt to enforce subordination
provisions contained in this Article X shall at any time in any way be prejudiced or impaired by
any act or failure to act on the part of the Company or the Subsidiary Guarantors, as the case may
be, or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by
the Company or the Subsidiary Guarantors, as the case may be, with the terms of this Indenture,
regardless of any knowledge thereof that any such holder may have or be otherwise charged with.
The holders of Senior Debt may extend, renew, modify or amend the terms of the Senior Debt or any
security therefor and release, sell or exchange such security and otherwise deal freely with the
Company or the Subsidiary Guarantors, as the case may be, all without affecting the liabilities and
obligations of the parties to this Indenture or the Holders of the Securities of any series and any
related Guarantees.

SECTION 10.09 Trustee to Effectuate Subordination of Securities.

          Each Holder of a Security of any series and any related Guarantees by his acceptance thereof
authorizes and expressly directs the Trustee on his behalf to take such action as may be necessary
or appropriate to effectuate the subordination provisions contained in this Article X and to
protect the rights of the Holders of the Securities and any related Guarantee of such series
pursuant to this Indenture, and appoints the Trustee his attorney-in-fact for such purpose,
including, in the event of any dissolution, winding up, liquidation or reorganization of the
Company or the Subsidiary Guarantors, as the case may be (whether in bankruptcy, insolvency or
receivership proceedings or upon an assignment for the benefit of creditors of the Company or the
Subsidiary Guarantors, as the case may be), the filing of a claim for the unpaid balance of his
Securities and any related Guarantees in the form required in said proceedings and cause said claim
to be approved. If the Trustee does not file a proper claim or proof of debt in the form required
in such proceeding prior to 30 days before the expiration of the time to file such claim or claims,
then the holders of the Senior Debt or their representative is hereby authorized to have the right
to file and is hereby authorized to file an appropriate claim for and on behalf of the Holders of
Securities of such series and any related Guarantees. Nothing contained herein shall be deemed to
authorize the Trustee or the holders of Senior Debt or their representative to authorize or consent
to or accept or adopt on behalf of any Holder of Securities of any series and any related
Guarantees any plan of reorganization, arrangement, adjustment or composition affecting the
Securities of such series and any related Guarantees or the rights of any Holder thereof, or to
authorize the Trustee or the holders of Senior Debt or their representative to vote in respect of
the claim of any Holder of the Securities of such series and any related Guarantees in any such
proceeding.

53

 

SECTION 10.10 Right of Trustee to Hold Senior Debt.

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

SECTION 10.11 Article X Not to Prevent Events of Default.

          The failure to make a payment on account of principal of or premium (if any) or interest on
the Securities of any series and any related Guarantees by reason of any provision of this Article
X shall not be construed as preventing the occurrence of a Default or an Event of Default under
Section 6.01 with respect to Securities of such series and any related Guarantees or in any way
prevent the Holders of the Securities of such series and any related Guarantees from exercising any
right hereunder other than the right to receive payment on the Securities of such series and any
related Guarantees.

SECTION 10.12 No Fiduciary Duty of Trustee to Holders of Senior Debt.

          The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt, and
shall not be liable to any such holders (other than for its willful misconduct or negligence) if it
shall in good faith mistakenly pay over or distribute to the Holders of the Securities of any
series and any related Guarantees or the Company or the Subsidiary Guarantors, as the case may be,
or any other Person, cash, property or securities to which any holders of Senior Debt shall be
entitled by virtue of this Article X or otherwise. Nothing in this Section 10.12 shall affect the
obligation of any other such Person to hold such payment for the benefit of, and to pay such
payment over to, the holders of Senior Debt or their representative.

SECTION 10.13 Article Applicable to Paying Agent.

          In case at any time any Paying Agent other than the Trustee shall have been appointed by the
Company and be then acting hereunder, the term “Trustee” as used in this Article X shall in such
case (unless the context shall otherwise require) be construed as extending to and including such
Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were
named in this Article X in addition to or in place of the Trustee; provided, however, that this
Section 10.13 shall not apply to the Company, any Subsidiary Guarantor or any other Subsidiary if
the Company, such Subsidiary Guarantor or such other Subsidiary acts as Paying Agent.

ARTICLE XI

GUARANTEE

SECTION 11.01 Guarantee.

          (a) Notwithstanding any provision of this Article XI to the contrary, the provisions of this
Article XI relating to the Subsidiary Guarantors shall be applicable only to, and

54

 

inure solely to
the benefit of, the Securities of any series designated, pursuant to Section 2.01, as entitled to
the benefits of the related Guarantee of each of the Subsidiary Guarantors.

          (b) For value received, each of the Subsidiary Guarantors hereby fully, unconditionally and
absolutely guarantees (each, a “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 11.03
and the subordination provisions contained in Article X.

          (c) Failing payment when due of any amount guaranteed pursuant to the related Guarantee, for
whatever reason, each of the Subsidiary Guarantors will be jointly and severally obligated to pay
the same immediately, subject to the subordination provisions contained in Article X. Each of the
Guarantees hereunder is intended to be a general, unsecured, subordinated obligation of the related
Subsidiary Guarantor and will rank pari passu in right of payment with all Debt of such Subsidiary
Guarantor that is not, by its terms, expressly subordinated in right of payment to such Guarantee.
Each of the Subsidiary Guarantors hereby agrees that its obligations hereunder shall be full,
unconditional and absolute, irrespective of the validity, regularity or enforceability of the
Securities, its Guarantee, the Guarantee of any other Subsidiary 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 Subsidiary Guarantor, or any action to enforce the same or any other circumstances which
might otherwise constitute a legal or equitable discharge or defense of the Subsidiary Guarantors.
Each of the Subsidiary 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 of such series, 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 6.06,
by the Holders, on the terms and conditions set forth in this Indenture, directly against such
Subsidiary Guarantor to enforce such Guarantee without first proceeding against the Company or any
other Subsidiary Guarantor.

          (d) The obligations of each of the Subsidiary Guarantors under this Article XI shall be as
aforesaid full, unconditional and absolute and shall not be impaired, modified, released or limited
by any occurrence or condition whatsoever, including, without limitation, (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 Subsidiary Guarantors contained
in the Securities or this Indenture, (ii) any impairment, modification, release or limitation of
the liability of the Company, any of the Subsidiary 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 Bankruptcy Law, as amended, or other statute or from the
decision of any court, (iii) the assertion or exercise by the Company, any of the Subsidiary
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 Subsidiary Guarantors under
this

55

 

Indenture, (v) the extension of the time for payment by the Company or any of the Subsidiary
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 the Subsidiary 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 Subsidiary 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 Subsidiary Guarantors or any of their respective
assets, or the disaffirmance of the Securities, the Guarantees or this Indenture in any such
proceeding, (viii) the release or discharge of the Company or any of the Subsidiary 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 of such series,
the related Guarantees or this Indenture or (x) any other circumstances (other than payment in full
or discharge of all amounts guaranteed pursuant to the related Guarantees) which might otherwise
constitute a legal or equitable discharge of a surety or guarantor.

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

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

SECTION 11.02 Execution and Delivery of Guarantees.

          To further evidence its Guarantee set forth in Section 11.01, each of the Subsidiary
Guarantors hereby agrees that a notation relating to such Guarantee, substantially in

56

 

the form
attached hereto as Annex A, shall be endorsed on each Security of the series entitled to the
benefits of such Guarantee authenticated and delivered by the Trustee, which notation of Guarantee
shall be executed by either manual or facsimile signature of an Officer of such Subsidiary
Guarantor. Each of the Subsidiary Guarantors hereby agrees that its Guarantee set forth in Section
11.01 shall remain in full force and effect notwithstanding any failure to endorse on each Security
a notation relating to such Guarantee. If any Officer of such Subsidiary Guarantor whose signature
is on this Indenture or a notation of Guarantee 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 of a series entitled to the benefits of a
Guarantee under this Article XI by the Trustee, after the authentication thereof hereunder, shall
constitute due delivery of the Guarantee set forth in this Indenture on behalf of each Subsidiary
Guarantor.

SECTION 11.03 Limitation on Liability of the Subsidiary Guarantors.

          Each Subsidiary Guarantor and by its acceptance hereof each Holder of a Security of a series
entitled to the benefits of a Guarantee under this Article XI hereby confirms that it is the
intention of all such parties that the guarantee by such Subsidiary Guarantor pursuant to its
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
such Guarantee and the Subsidiary Guarantors hereby irrevocably agree that the obligations of each
Subsidiary Guarantor under its Guarantee shall be limited to the maximum amount as will, after
giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor and to any
collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of
the obligations of such other Subsidiary Guarantor under its Guarantee, result in the obligations
of such Subsidiary Guarantor under its Guarantee not constituting a fraudulent conveyance or
fraudulent transfer under federal or state law.

SECTION 11.04 Release of Subsidiary Guarantors from Guarantee.

          (a) Notwithstanding any other provisions of this Indenture, the Guarantee of any Subsidiary
Guarantor may be released upon the terms and subject to the conditions set forth in this Section
11.04. Provided that no Default shall have occurred and shall be continuing under this Indenture,
any Guarantee incurred by a Subsidiary Guarantor pursuant to this Article XI 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 equity interests in such Subsidiary Guarantor (provided
such sale, exchange or transfer is not prohibited by this Indenture) or
(B) the merger of such Subsidiary Guarantor into the Company or any other Subsidiary Guarantor
or the liquidation and dissolution of such Subsidiary Guarantor (in each case to the extent not
prohibited by this Indenture) or (ii) following delivery of a written notice of such release or
discharge by the Company to the Trustee, upon the release or discharge of all guarantees by such
Subsidiary Guarantor of any Debt of the Company other than obligations arising under this Indenture
and any Securities issued hereunder, except a discharge or release by or as a result of payment
under such guarantees.

57

 

          (b) The Trustee shall deliver an appropriate instrument evidencing any release of a Subsidiary
Guarantor from its Guarantee upon receipt of a written request of the Company accompanied by an
Officers’ Certificate and an Opinion of Counsel that the Subsidiary Guarantor is entitled to such
release in accordance with the provisions of this Indenture. If the Subsidiary Guarantor is not so
