Holders in person or by agent duly appointed in writing; and, except as herein otherwise
expressly provided, such action shall become effective when such instrument or instruments
are delivered to the Trustee and, where it is hereby expressly required, to the Company or
the Guarantors. Such instrument or instruments (and the action embodied therein and

the Holders signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any purpose of
this Indenture and (subject to Section 315 of the Trust Indenture Act) conclusive in favor
of the Trustee, the Company and, if applicable, the Guarantors, if made in the manner

the Trustee, the Company or, if applicable, the Guarantors in reliance thereon, regardless
of whether notation of such action is made upon such Security.

     (e) Without limiting the foregoing, a Holder entitled to give or take any action
hereunder with regard to any particular Security may do so with regard to all or any part of
the principal amount of such Security or by one or more duly appointed agents each of which
may do so pursuant to such appointment with regard to all or any different part of such
principal amount.

     (f) The Company may set any day as the record date for the purpose of determining the
Holders of Outstanding Securities of any series entitled to give or take any request,
demand, authorization, direction, notice, consent, waiver or other Act provided or permitted
by this Indenture to be given or taken by Holders of Securities of such series, but the
Company shall have no obligation to do so. With regard to any record date set pursuant to
this paragraph, the Holders of Outstanding Securities of the relevant series on such record
date (or their duly appointed agents), and only such Persons, shall be entitled to give or
take the relevant action, regardless of whether such Holders remain Holders after such

if sent by overnight air courier guaranteeing next day delivery.

The Trustee may rely upon and comply with instructions or directions sent via unsecured facsimile
or email transmission and the Trustee shall not be liable for any loss, liability or expense of any
kind incurred by the Issuer or the Holders due to the Trustee’s reliance upon and compliance with
instructions or directions given by unsecured facsimile or email transaction; provided, however,
that such losses have not arisen from the negligence or willful misconduct of the Trustee, it being
understood that the failure of the Trustee to verify or confirm that the person providing the
instructions or directions, is, in fact, an authorized person does not constitute negligence or
willful misconduct.

Section 1.7. Notice to Holders; Waiver.

     Where this Indenture provides for notice to Holders of any event, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing and mailed,
first-class postage prepaid, to each Holder affected by such event, at his address as it appears in
the Security Register, not later than the latest date, and not earlier than the earliest date,
prescribed for the giving of such notice. In any case where notice to Holders is given by mail,
neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular
Holder shall affect the sufficiency of such notice with respect to other
Holders. Any notice mailed to a Holder in the manner herein prescribed shall be conclusively
deemed to have been received by such Holder, regardless of whether such Holder actually receives
such notice.

     Where this Indenture provides for notice in any manner, such notice may be waived in writing
by the Person entitled to receive such notice, either before or after the event, and such waiver
shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

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

Section 1.8. Conflict with Trust Indenture Act.

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

action taken by Holders of Securities pursuant to the terms of this Indenture.

necessary to convert the sum due in respect of the principal of or interest on the Securities of
any series (the “Required Currency”) into a currency in which a judgment will be rendered (the
“Judgment Currency”), the rate of exchange used shall be the rate at which in accordance with
normal banking procedures the Trustee could purchase in The City of New York the Required Currency
with the Judgment Currency on the day on which final unappealable judgment is entered, unless such
day is not a Banking Day, then, to the extent permitted by applicable law, the rate of exchange
used shall be the rate at which in accordance with normal banking procedures the Trustee could
purchase in The City of New York the Required Currency with the Judgment Currency on the Banking
Day next preceding the day on which final unappealable judgment is entered and (b) its obligations
under this Indenture to make payments in the Required Currency (i) shall not be discharged or
satisfied by any tender, or any recovery pursuant to any judgment (regardless of whether entered in
accordance with subclause (a)), in any currency other than the Required

13

 

Currency, except to the
extent that such tender or recovery shall result in the actual receipt, by the payee, of the full
amount of the Required Currency expressed to be payable in respect of such payments, (ii) shall be
enforceable as an alternative or additional cause of action for the purpose of recovering in the
Required Currency the amount, if any, by which such actual receipt shall fall short of the full
amount of the Required Currency so expressed to be payable and (iii) shall not be affected by
judgment being obtained for any other sum due under this Indenture.

     (j) whether payment of principal of and premium, if any, and interest, if any, on the
Securities of the series shall be without deduction for taxes, assessments or governmental

     (k) if other than the principal amount thereof, the portion of the principal amount of
Securities of the series which shall be payable upon declaration of acceleration of the
Maturity thereof pursuant to Section 5.2;

     (l) if the amount of payments of principal of and any premium or interest on the
Securities of the series may be determined with reference to an index, the manner in which
such amounts shall be determined;

     (m) if and as applicable, that the Securities of the series shall be issuable in whole
or in part in the form of one or more Global Securities and, in such case, the Depositary or
Depositaries for such Global Security or Global Securities and any circumstances other than
those set forth in Section 3.5 in which any such Global Security may be transferred to, and
registered and exchanged for Securities registered in the name of, a Person other than the
Depositary for such Global Security or a nominee thereof and in which any such transfer may
be registered;

     (n) any deletions from, modifications of or additions to the Events of Default set
forth in Section 5.1 or the covenants of the Company set forth in Article Ten with respect
to the Securities of such series;

     (o) whether and under what circumstances the Company will pay additional amounts on the
Securities of the series held by a Person who is not a U.S. Person in respect of any tax,
assessment or governmental charge withheld or deducted and, if so, whether the Company will
have the option to redeem the Securities of the series rather than pay such additional
amounts;

     (p) if the Securities of the series are to be issuable in definitive form (whether upon
original issue or upon exchange of a temporary Security of such series) only upon receipt of
certain certificates or other documents or satisfaction of other conditions, the form and
terms of such certificates, documents or conditions;

24

 

     (q) if the Securities of the series are to be convertible into or exchangeable for any
other security or property of the Company, including, without limitation, securities of
another Person held by the Company or its Affiliates and, if so, the terms thereof;

     (r) if other than as provided in Section 13.2 and Section 13.3, the means of Legal

provisions of this Indenture).

     All Securities of any one series shall be substantially identical except as to denomination
and except as may otherwise be provided in or pursuant to the Board Resolution referred to above
and (subject to Section 3.3) set forth, or determined in the manner provided, in the Officer’s
Certificate referred to above or in any such indenture supplemental hereto.

     All Securities of any one series need not be issued at the same time and, unless otherwise
provided, a series may be reopened, without the consent of the Holders, for increases in the
aggregate principal amount of such series of Securities and issuances of additional Securities of
such series or for the establishment of additional terms with respect to the Securities of such
series.

     If any of the terms of the series are established by action taken by or pursuant to a Board
Resolution, a copy of an appropriate record of such action shall be certified by an authorized
officer or other authorized person on behalf of the Company and, if applicable, the Guarantors and
delivered to the Trustee at or prior to the delivery of the Officer’s Certificate setting forth, or
providing the manner for determining, the terms of the series.

     With respect to Securities of a series subject to a Periodic Offering, such Board Resolution
or Officer’s Certificate may provide general terms for Securities of such series and provide either
that the specific terms of particular Securities of such series shall be specified in a Company
Order or that such terms shall be determined by the Company and, if applicable, the Guarantors or
one or more agents thereof designated in an Officer’s Certificate, in accordance with a Company
Order.

Section 3.2. Denominations.

     The Securities of each series shall be issuable in registered form without coupons in such
denominations as shall be specified as contemplated by Section 3.1. In the absence of any such
provisions with respect to the Securities of any series, the Securities of such series shall be
issuable in denominations of $1,000 and any integral multiple thereof.

Section 3.3. Execution, Authentication, Delivery and Dating.

     The Securities shall be executed on behalf of the Company by its Chairman of the Board, its
Chief Executive Officer, its President, its Chief Financial Officer or any of its Vice Presidents
and need not be attested. The signature of any of these officers on the Securities may be manual
or facsimile. Any

25

 

Securities Guarantee endorsed on the Securities shall be executed on behalf of
the applicable Guarantor by its Chairman of the Board, its Chief Executive Officer, its President,
its Chief Financial Officer or any of its Vice Presidents and need not be attested. The signature
of any of these officers on any endorsement of the Securities Guarantee may be manual or facsimile.

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

     At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Securities of any series executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and delivery of such
Securities, and the Trustee in accordance with the Company Order shall authenticate and deliver
such Securities; provided, however, that in the case of Securities offered in a Periodic Offering,
the Trustee shall authenticate and deliver such Securities from time to time in accordance with
such other procedures (including, without limitation, the receipt by the Trustee of electronic
instructions from the Company or its duly authorized agents, thereafter promptly confirmed in
writing) acceptable to the Trustee as may be specified by or pursuant to a Company Order delivered
to the Trustee prior to the time of the first authentication of Securities of such series. If the
forms or terms of the Securities of the series have been established in or pursuant to one or more
Board Resolutions as permitted by Section 2.1 and Section 3.1, in authenticating such Securities,
and accepting the additional responsibilities under this Indenture in relation to such Securities,
the Trustee shall be entitled to receive such documents as it may reasonably request. The Trustee
shall also be entitled to receive, in addition to the documents set forth in Section 1.3, and
(subject to Section 6.1) shall be fully protected in relying upon, an Opinion of Counsel stating:

     (a) if the form or forms of such Securities has been established in or pursuant to a
Board Resolution as permitted by Section 2.1, that each such form has been established in
conformity with the provisions of this Indenture;

     (b) if the terms of such Securities have been, or in the case of Securities of a series
offered in a Periodic Offering will be, established in or pursuant to a Board Resolution as
permitted by Section 3.1, that such terms have been, or in the case of Securities of a
series offered in a Periodic Offering will be, established in conformity with the provisions
of this Indenture, subject, in the case of Securities of a series offered in a Periodic
Offering, to any conditions specified in such Opinion of Counsel; and

     (c) that such Securities when authenticated and delivered by the Trustee and issued by
the Company in the manner and subject to any conditions and assumptions specified in such
Opinion of Counsel, will constitute valid and legally binding obligations of the Company
and, if applicable, the Guarantors, enforceable in accordance with their terms, subject to
the following limitations: (i) bankruptcy, insolvency, moratorium, reorganization,
liquidation, fraudulent conveyance or transfer and other similar laws of general
applicability relating to or affecting the enforcement of creditors’ rights, or to general
equity principles, (ii) the availability of equitable remedies being subject to the
discretion of the court to which application therefor is made; and (iii) such other usual
and customary matters as shall be specified in such Opinion of Counsel.

If such form or forms or terms have been so established, the Trustee shall not be required to
authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect
the Trustee’s own

26

 

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

     Notwithstanding the provisions of Section 3.1 and of the preceding paragraph, if all
Securities of a series are not to be originally issued at one time, it shall not be necessary to
deliver the Officer’s Certificate otherwise required pursuant to Section 3.1 or the Company Order
and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the time of
authentication of each Security of such series if such documents are delivered at or prior to the
authentication upon original issuance of the first Security of such series to be issued.

     With respect to Securities of a series offered in a Periodic Offering, the Trustee may rely,
as to the authorization by the Company of any of such Securities, on the form or forms and terms
thereof and the legality, validity, binding effect and enforceability thereof, upon the Opinion of
Counsel and the other documents delivered pursuant to Section 2.1 and Section 3.1 and this Section,
as applicable, in connection with the first authentication of Securities of such series.

     Each Security shall be dated the date of its authentication.

     No Security, nor any Securities Guarantee endorsed thereon, shall be entitled to any benefit
under this Indenture or be valid or obligatory for any purpose unless there appears on such
Security a certificate of authentication substantially in the form provided for herein executed by
the Trustee by manual signature of an authorized officer, and such certificate upon any Security
shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated
and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the
foregoing, if any Security shall have been authenticated and delivered hereunder but never issued
and sold by the Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided in Section 3.9, for all purposes of this Indenture such Security shall be
deemed never to have been authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

Section 3.4. Temporary Securities.

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

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

27

 

Section 3.5. Registration, Registration of Transfer and Exchange.

     The Company shall cause to be kept at the office or agency of the Company in a Place of
Payment required by Section 10.2 a register (the register maintained in such office being herein
sometimes referred to as the “Security Register”) in which, subject to such reasonable regulations
as it may prescribe, the Company shall provide for the registration of Securities and of transfers
of Securities. The Trustee is hereby appointed as the initial “Security Registrar” for the purpose
of registering Securities and transfers of Securities as herein provided, and its corporate trust
office, which, at the date hereof, is located at 601 Travis Street, 16th Floor, Houston,
Texas 77002, is the initial office or agency where the Securities Register will be maintained. The
Company may at any time replace such Security Registrar, change such office or agency or act as its
own Security Registrar. The Company will give prompt written notice to the Trustee of any change
of the Security Registrar or of the location of such office or agency.

     Upon surrender for registration of transfer of any Security of any series at the office or
agency maintained pursuant to Section 10.2 for such purpose, the Company and, if applicable, the
Guarantors shall execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Securities, with an endorsement of the
Securities Guarantee, if applicable, executed by the Guarantors, of the same series and tenor, of
any authorized denominations and of a like aggregate principal amount.

     At the option of the Holder, Securities of any series (except a Global Security) may be
exchanged for other Securities of the same series and tenor, of any authorized denominations and of
a like aggregate principal amount, upon surrender of the Securities to be exchanged at such office
or agency. Whenever any Securities are so surrendered for exchange, the Company and, if
applicable, the Guarantors shall execute and the Trustee shall authenticate and deliver, the
Securities, with an endorsement of the Securities Guarantee, if applicable, executed by the
Guarantors, which the Holder making the exchange is entitled to receive.

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

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

     No service charge shall be made for any registration of transfer or exchange of Securities,
but the Company and the Trustee may require payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection with any registration of transfer or exchange
of Securities, other than exchanges pursuant to Section 3.4, Section 9.6 or Section 11.7 not
involving any transfer.

     The Company shall not be required (a) to issue, register the transfer of or exchange
Securities of any series during a period beginning at the opening of business 15 days before the
day of the mailing of a notice of redemption of Securities of that series selected for redemption
under Section 11.3 and ending at the close of business on the day of such mailing, or (b) to
register the transfer of or exchange any Security
so selected for redemption in whole or in part, except the unredeemed portion of any Security
being redeemed in part.

28

 

     Notwithstanding any other provisions of this Indenture and except as otherwise specified with
respect to any particular series of Securities as contemplated by Section 3.1, a Global Security
representing all or a portion of the Securities of a series may not be transferred, except as a
whole by the Depositary for such series to a nominee of such Depositary or by a nominee of such
Depositary to such Depositary or another nominee of such Depositary or by such Depositary or any
such nominee to a successor Depositary for such series or a nominee of such successor Depositary.
Every Security authenticated and delivered upon registration of, transfer of, or in exchange for or
in lieu of, a Global Security shall be a Global Security except as provided in the two paragraphs
immediately following.

     If at any time the Depositary for any Securities of a series represented by one or more Global
Securities notifies the Company that it is unwilling or unable to continue as Depositary for such
Securities or if at any time the Depositary for such Securities shall no longer be eligible to
continue as Depositary under Section 3.1 or ceases to be a clearing agency registered under the
Exchange Act, the Company shall appoint a successor Depositary with respect to such Securities. If
a successor Depositary for such Securities is not appointed by the Company within 90 days after the
Company receives such notice or becomes aware of such ineligibility, the Company’s election
pursuant to Section 3.1 that such Securities be represented by one or more Global Securities shall
no longer be effective and the Company and, if applicable, the Guarantors will execute and the
Trustee, upon receipt of a Company Order for the authentication and delivery of Definitive
Securities of such series, will authenticate and deliver, Securities, with an endorsement of the
Securities Guarantee, if applicable, executed by the Guarantors, of such series in definitive
registered form without coupons, in any authorized denominations, in an aggregate principal amount
equal to the principal amount of the Global Security or Securities representing such Securities in
exchange for such Global Security or Securities registered in the names of such Persons as the
Depositary shall direct.

     The Company may at any time and in its sole discretion determine that the Securities of any
series issued in the form of one or more Global Securities shall no longer be represented by a
Global Security or Securities. In such event, the Company and, if applicable, the Guarantors will
execute and the Trustee, upon receipt of a Company Order for the authentication and delivery of
Definitive Securities of such series, will authenticate and deliver, Securities, with an
endorsement of the Securities Guarantee, if applicable, executed by the Guarantors, of such series
in definitive registered form without coupons, in any authorized denominations, in an aggregate
principal amount equal to the principal amount of the Global Security or Securities representing
such Securities in exchange for such Global Security or Securities registered in the names of such
Persons as the Depositary shall direct.

     If specified by the Company pursuant to Section 3.1 with respect to Securities represented by
a Global Security, the Depositary for such Global Security may surrender such Global Security in
exchange in whole or in part for Securities of the same series and tenor in definitive registered
form on such terms as are acceptable to the Company, the Trustee and such Depositary. Thereupon,
the Company and, if applicable, the Guarantors shall execute, and the Trustee, upon receipt of a
Company Order for the authentication and delivery of Securities in definitive registered form,
shall authenticate and deliver, without service charge:

     (i) to the Person specified by such Depositary a new Security or Securities, with an
endorsement of the Securities Guarantee, if applicable, executed by the Guarantors, of the
same series and tenor, of any authorized denominations as requested by such Person, in an
aggregate principal amount equal to and in exchange for such Person’s beneficial interest in
the Global Security; and

     (ii) to such Depositary a new Global Security, with an endorsement of the Securities
Guarantee, if applicable, executed by the Guarantors, in a denomination equal to the
difference, if

29

 

any, between the principal amount of the surrendered Global Security and the
aggregate principal amount of Securities authenticated and delivered pursuant to clause (i)
above.

     Every Person who takes or holds any beneficial interest in a Global Security agrees that:

     (A) the Company, the Guarantors (if applicable) and the Trustee may deal with the
Depositary as sole owner of the Global Security and as the authorized representative of such
Person;

     (B) such Person’s rights in the Global Security shall be exercised only through the
Depositary and shall be limited to those established by law and agreement between such
Person and the Depositary and/or direct and indirect participants of the Depositary;

     (C) the Depositary and its participants make book-entry transfers of beneficial
ownership among, and receive and transmit distributions of the principal of (and premium, if
any) and interest on the Global Securities to, such Persons in accordance with their own
procedures; and

     (D) none of the Company, the Guarantors (if applicable), the Trustee, nor any agent of
any of them will have any responsibility or liability for any aspect of the records relating
to or payments made on account of beneficial ownership interests of a Global Security or for
maintaining, supervising or reviewing any records relating to such beneficial ownership
interests.

Section 3.6. Mutilated, Destroyed, Lost and Stolen Securities.

     If any mutilated Security is surrendered to the Trustee, together with, in proper cases, such
security or indemnity as may be required by the Company, the Guarantors (if applicable) or the
Trustee to save each of them and any agent of any of them harmless, the Company and, if applicable,
the Guarantors shall execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security, with an endorsement of the Securities Guarantee, if applicable, executed by the
Guarantors, of the same series and of like tenor and principal amount and bearing a number not
contemporaneously outstanding.

     If there shall be delivered to the Company, the Guarantors (if applicable) and the Trustee (a)
evidence to their satisfaction of the destruction, loss or theft of any Security and (b) such
security or indemnity as may be required by them to save each of them and any agent of any of them
harmless, then, in the absence of notice to the Company or the Trustee that such Security has been
acquired by a bona fide purchaser, the Company and, if applicable, the Guarantors shall execute and
the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security,
a new Security, with an endorsement of the Securities Guarantee, if applicable, executed by the
Guarantors, of the same series and of like tenor and principal amount and bearing a number not
contemporaneously outstanding.

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

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

     Every new Security of any series issued pursuant to this Section in lieu of any destroyed,
lost or stolen Security shall constitute an original additional contractual obligation of the
Company and, if applicable, the Guarantors, regardless of whether the destroyed, lost or stolen
Security shall be at any time

30

 

enforceable by anyone, and shall be entitled to all the benefits of
this Indenture equally and proportionately with any and all other Securities of that series duly
issued hereunder.

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

Section 3.7. Payment of Interest; Interest Rights Preserved.

     Except as otherwise provided as contemplated by Section 3.1 with respect to any series of
Securities, interest on any Security which is payable, and is punctually paid or duly provided for,
on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or
more Predecessor Securities) is registered at the close of business on the Regular Record Date for
such interest.

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

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

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

31

 

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

Section 3.8. Persons Deemed Owners.

     Except as otherwise provided as contemplated by Section 3.1 with respect to any series of
Securities, prior to due presentment of a Security for registration of transfer, the Company, the
Trustee and, if applicable, the Guarantors and any agent thereof may treat the Person in whose name
such Security is registered as the owner of such Security for the purpose of receiving payment of
principal of and any premium and (subject to Section 3.5 and Section 3.7) any interest on such
Security and for all other purposes whatsoever, regardless of whether such Security be overdue, and
none of the Company, the Trustee nor, if applicable, the Guarantors nor any agent of any of them
shall be affected by notice to the contrary.

     No holder of any beneficial interest in any Global Security held on its behalf by a Depositary
shall have any rights under this Indenture with respect to such Global Security, and such
Depositary may be treated by the Company, the Trustee, and, if applicable, the Guarantors and any
agent of thereof as the owner of such Global Security for all purposes whatsoever.

Section 3.9. Cancellation.

     All Securities surrendered for payment, redemption, registration of transfer or exchange or
for credit against any sinking fund payment shall, if surrendered to any Person other than the
Trustee, be delivered to the Trustee and shall be promptly canceled by it. The Company may at any
time deliver to the Trustee for cancellation any Securities previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the
Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold, and all Securities so
delivered shall be promptly canceled by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities canceled as provided in this Section, except as expressly
permitted by this Indenture. All canceled Securities held by the Trustee shall be disposed of in
accordance with its customary practices, and the Trustee shall thereafter deliver to the Company a
certificate with respect to such disposition from time to time upon written request.

Section 3.10. Computation of Interest.

     Except as otherwise specified as contemplated by Section 3.1 for Securities of any series,
interest on the Securities of each series shall be computed on the basis of a year of twelve 30-day
months.

Section 3.11. CUSIP or CINS Numbers.

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

instruments acknowledging satisfaction and discharge of this Indenture with respect to such

ARTICLE FIVE

REMEDIES

Section 5.1. Events of Default.

     “Event of Default,” wherever used herein with respect to Securities of any series, means any
one of the following events (whatever the reason for such Event of Default and whether it shall be
voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or
order of any court or any order, rule or regulation of any administrative or governmental body):

     (a) default in the payment of any interest upon any Security of that series when it
becomes due and payable, and continuance of such default for a period of 30 days; or

     (b) default in the payment of the principal of (or premium, if any, on) any Security of
that series at its Maturity; or

     (c) default in the performance, or breach, of any covenant set forth in Article Ten in
this Indenture (other than a covenant a default in the performance of which or the breach of
which is
elsewhere in this Section specifically dealt with or which has expressly been included
in this Indenture solely for the benefit of series of Securities other than that series),
and continuance of such default or breach for a period of 90 days after there has been
given, by registered or certified mail, to the Company by the Trustee or to the Company and
the Trustee by the Holders of at least 25% in principal amount of the Outstanding Securities
of that series a written notice specifying such default or breach and requiring it to be
remedied and stating that such notice is a “Notice of Default” hereunder; or

     (d) default in the performance, or breach, of any covenant in this Indenture (other
than a covenant in Article Ten or any other covenant a default in the performance of which
or the breach of which is elsewhere in this Section specifically dealt with or which has
expressly been included in this Indenture solely for the benefit of series of Securities
other than that series), and continuance of such default or breach for a period of 180 days
after there has been given, by registered or certified mail, to the Company by the Trustee
or to the Company and the Trustee by the Holders of at least 25% in principal amount of the
Outstanding Securities of that series a written notice specifying such default or breach and
requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder;
or

34

 

     (e) the Company pursuant to or within the meaning of any Bankruptcy Law (i) commences a
voluntary case, (ii) consents to the entry of any order for relief against it in an
involuntary case, (iii) consents to the appointment of a Custodian of it or for all or
substantially all of its property, or (iv) makes a general assignment for the benefit of its
creditors; or

     (f) a court of competent jurisdiction enters an order or decree under any Bankruptcy
Law that (i) is for relief against the Company in an involuntary case, (ii) appoints a
Custodian of the Company or for all or substantially all of its property, or (iii) orders
the liquidation of the Company; and the order or decree remains unstayed and in effect for
60 consecutive days; or

     (g) default in the deposit of any sinking fund payment when due; or

     (h) any other Event of Default provided with respect to Securities of that series in
accordance with Section 3.1.

Section 5.2. Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default with respect to Securities of any series at the time Outstanding occurs
and is continuing, then in every such case the Trustee or the Holders of 25% in aggregate principal
amount of the Outstanding Securities of that series may declare the principal amount (or, if the
Securities of that series are Original Issue Discount Securities, such portion of the principal
amount as may be specified in the terms of that series) of all of the Securities of that series to
be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such principal amount (or specified amount) shall become
immediately due and payable. Notwithstanding the foregoing, if an Event of Default specified in
clause (e) or (f) of Section 5.1 occurs, the Securities of any series at the time Outstanding shall
be due and payable immediately without further action or notice.

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

     (a) the Company or, if applicable, one or more of the Guarantors has paid or deposited
with the Trustee a sum sufficient to pay:

     (i) all overdue interest on all Securities of that series;

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

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

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

35

 

     (b) all Events of Default with respect to Securities of that series, other than the
non-payment of the principal of Securities of that series which have become due solely by
such declaration of acceleration, have been cured or waived as provided in Section 5.13.

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

Section 5.3. Collection of Indebtedness and Suits for Enforcement by Trustee.

     The Company covenants that if:

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

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

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

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

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

Section 5.4. Trustee May File Proofs of Claim.

     In case of the pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the
Company or, if applicable, any Guarantor or any other obligor upon the Securities, their property
or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then
be due and payable as therein expressed or by declaration or otherwise and irrespective of whether
the Trustee shall have made any demand on the Company or, if applicable, the Guarantors for the
payment of overdue principal or interest) shall be entitled and empowered, by intervention in such
proceeding or otherwise:

     (a) to file and prove a claim for the whole amount of principal (and premium, if any)
and interest owing and unpaid in respect of the Securities and to file such other papers or
documents

36

 

as may be necessary or advisable in order 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 of the Holders allowed in such judicial
proceeding; and

     (b) to collect and receive any moneys or other property payable or deliverable on any
such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder to make such payments to the
Trustee and, if the Trustee shall consent to the making of such payments directly to the Holders,
to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 6.7.

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

Section 5.5. Trustee May Enforce Claims Without Possession of Securities.

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

Section 5.6. Application of Money Collected.

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

     FIRST: To the payment of all amounts due the Trustee under Section 6.7;

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

     THIRD: The balance, if any, to the Company.

Section 5.7. Limitation on Suits.

     No Holder of any Security of any series shall have any right to institute any proceeding,
judicial or otherwise, with respect to this Indenture (including, if applicable, the Securities
Guarantee), or for the appointment of a receiver or trustee, or for any other remedy hereunder,
unless:

37

 

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

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

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

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

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

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

Section 5.8. Unconditional Right of Holders to Receive Principal, Premium and Interest.

     Notwithstanding any other provision in this Indenture, the Holder of any Security shall have
the right, which is absolute and unconditional (subject to Section 3.7 and Section 9.2), to receive
payment of the principal of and any premium and interest on such Security on the Stated Maturity
or Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date)
and to institute suit for the enforcement of any such payment, and such rights shall not be
impaired without the consent of such Holder.

Section 5.9. Restoration of Rights and Remedies.

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

Section 5.10. Rights and Remedies Cumulative.

     Except as otherwise provided with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities in the last paragraph of Section 3.6, no right or remedy
herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of
any other right or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

38

 

Section 5.11. Delay or Omission Not Waiver.

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

Section 5.12. Control by Holders.

     The Holders of not less than a majority in principal amount of the Outstanding Securities of
any series shall have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee,
with respect to the Securities of such series; provided, however, that:

     (a) such direction shall not be in conflict with any rule of law or with this
Indenture;

     (b) the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction; and

     (c) subject to the provisions of Section 6.1, the Trustee shall have the right to
decline to follow any such direction if the Trustee in good faith shall determine that the
proceeding so directed would involve the Trustee in personal liability.

Section 5.13. Waiver of Past Defaults.

     By written notice to the Company and the Trustee, the Holders of not less than a majority in
principal amount of the Outstanding Securities of any series may, subject to Section 5.2(a)(iv), on
behalf of the Holders of all the Securities of such series waive any past default hereunder with
respect to such series and its consequences, except:

     (a) a continuing default in the payment of the principal of or any premium or interest
on any Security of such series; or

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

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

Section 5.14. Undertaking for Costs.

     All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof
shall be deemed to have agreed, that any court may in its discretion require, in any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any
action taken, suffered or omitted by it as Trustee, the filing by any party litigant, other than
the Trustee, in such suit of an undertaking to pay the costs of such suit, and that such court may
in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party
litigant in such suit, having due

39

 

regard to the merits and good faith of the claims or defenses
made by such party litigant; but the provisions of this Section 5.14 shall not apply to any suit
instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Securities of any series, or to any suit instituted by any Holder for the enforcement
of the payment of the principal of (or premium, if any) or interest on any Security on or after the
Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date).

Section 5.15. Waiver of Stay or Extension Laws.

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

ARTICLE SIX

Section 6.1. Certain Duties and Responsibilities.

     (a) Except during the continuance of an Event of Default:

     (i) the Trustee undertakes to perform such duties and only such duties as are
specifically set forth in this Indenture and as are provided by the Trust Indenture
Act, and no implied covenants or obligations shall be read into this Indenture
against the Trustee; and

     (ii) 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; but in the case of any such
certificates or opinions which by any provision hereof are specifically required to
be furnished to the Trustee, the Trustee shall be under a duty to examine the same
to determine whether they conform to the requirements of this Indenture.

     (b) In case 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 their exercise, as a prudent man would exercise or use under the
circumstances in the conduct of his own affairs.

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

     (i) this Subsection shall not be construed to limit the effect of Subsection
(a) of this Section;

40

 

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

conducting any proceeding for any remedy available to the Trustee, or exercising any
trust or power conferred upon the Trustee, under this Indenture with respect to the
Securities of such series; and

     (iv) no provision of this Indenture shall require the Trustee to expend or risk
its own funds or otherwise incur any financial liability in the performance of any
of its duties hereunder, or in the exercise of any of its rights or powers, if it
shall have reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.

     (d) Regardless of whether therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording protection to
the Trustee shall be subject to the provisions of this Section.

Section 6.2. Notice of Defaults.

to the Trustee, unless such Default shall have been cured or waived; provided, however, that,
except in the case of a Default in the payment of the principal of or any premium or interest on
any Security of such series or in the payment of any sinking fund installment with respect to
Securities of such series, the Trustee may withhold from Holders of Securities notice of any
continuing Default or Event of Default if a Responsible Officer of the Trustee in good faith
determines that the withholding of such notice is in the interest of the Holders of Securities of
such series; and, provided, further, that in the case of any Default of the character specified in
Section 5.1(c) with respect to Securities of such series, no such notice to Holders shall be given
until at least 90 days after the occurrence thereof and that in the case of any Default of the

indebtedness or other paper or document believed by it to be genuine and to have been signed

Officer’s Certificate;

compliance with such request or direction;

Officer’s Certificate may be signed by any person authorized to sign an Officer’s
Certificate, including any person specified as so authorized in any such certificate
previously delivered and not superseded;

     (i) the Trustee shall be entitled to the rights and protections afforded to the Trustee

Neither the Trustee nor any Authenticating Agent makes any representations as to the validity or
sufficiency of this Indenture or of the Securities. The Trustee or any Authenticating Agent shall
not be accountable for the use or application by the Company of Securities or the proceeds thereof.

Section 6.5. May Hold Securities.

     The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other
agent of the Company or, if applicable, any Guarantor, in its individual or any other capacity, may
become the owner or pledgee of Securities and, subject to Sections 310(b) and 311 of the Trust
Indenture Act and Section 6.8, Section 6.9 and Section 6.13, may otherwise deal with the Company

one or more of the Guarantors.

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

     (b) except as otherwise expressly provided herein, to reimburse the Trustee upon its
request for all reasonable expenses, disbursements and advances incurred or made by the

duties hereunder.

     As security for the performance of the obligations of the Company under this Section, the
Trustee shall have a lien prior to the Securities upon all property and funds held or collected by
the Trustee as

43

 

such, except funds held in trust for the payment of the principal of (and premium,
if any) or interest on particular Securities.

     Without limiting any rights available to the Trustee under applicable law, when the Trustee
incurs expenses or renders services in connection with an Event of Default specified in Section

counsel) and the compensation for the services of the Trustee are intended to constitute expenses

     The provisions of this Section 6.7 shall survive the resignation or removal of the Trustee and
the termination or satisfaction and discharge of this Indenture and the Legal Defeasance of the
Securities.

the operation of Section 310(b)(1) of the Trust Indenture Act this Indenture with respect to the
Securities of more than one series.

Section 6.9. Corporate Trustee Required; Eligibility.

     There shall at all times be a Trustee hereunder which shall be a corporation organized and
doing business under the laws of the United States of America, any State thereof or the District of
Columbia, authorized under such laws to exercise corporate trust powers, having a combined capital
and surplus required by the Trust Indenture Act, subject to supervision or examination by Federal
or State authority. If such corporation publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then for the purposes of
this Section, the combined capital and surplus of such corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition so published. The
Trustee shall not be an obligor upon the Securities or an Affiliate thereof. If at any time the
Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall
resign immediately in the manner and with the effect hereinafter specified in this Article Six.

Section 6.10. Resignation and Removal; Appointment of Successor.

     (a) No resignation or removal of the Trustee and no appointment of a successor Trustee
pursuant to this Article shall become effective until the acceptance of appointment by the
successor Trustee in accordance with the applicable requirements of Section 6.11.

     (b) The Trustee may resign at any time with respect to the Securities of one or more
series by giving written notice thereof to the Company. If the instrument of acceptance of
appointment by a successor Trustee required by Section 6.11 shall not have been delivered to
the Trustee within 30 days after the giving of such notice of resignation, the resigning
Trustee may petition any court of competent jurisdiction for the appointment of a successor
Trustee with respect to the Securities of such series.

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

44

 

     (d) If at any time:

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

     (ii) the Trustee shall cease to be eligible under Section 6.9 and shall fail to
resign after written request therefor by the Company or by any such Holder; or

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

then, in any such case, (A) the Company by a Board Resolution may remove the Trustee
with respect to all Securities, or (B) subject to Section 5.14, any Holder who has
been a bona fide Holder of a Security for at least six months may, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and the
appointment of a successor Trustee or Trustees.

     (e) If the Trustee shall resign, be removed or become incapable of acting, or if a
vacancy shall occur in the office of Trustee for any cause, with respect to the Securities
of one or more series, the Company, by a Board Resolution, shall promptly appoint a
successor Trustee or Trustees with respect to the Securities of that or those series (it
being understood that any such successor Trustee may be appointed with respect to the
Securities of one or more or all of such series and that at any time there shall be only one
Trustee with respect to the Securities of any particular series) and shall comply with the
applicable requirements of Section 6.11. If, within one year after such resignation,
removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect
to the Securities of any series shall be appointed by Act of the Holders of a majority in
principal amount of the Outstanding Securities of such series delivered to the Company and
the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its
acceptance of such appointment in accordance with the applicable requirements of Section
6.11, become the successor Trustee with respect to the Securities of such series and to that
extent supersede the successor Trustee appointed by the Company. If no successor Trustee
with respect to the Securities of any series shall have been so appointed by the Company or
the Holders and accepted appointment in the manner required by Section 6.11, the Trustee or
any Holder who has been a bona fide Holder of a Security of such series for at least six
months may, on behalf of himself and all others similarly situated, petition, at the expense
of the Company, any court of competent jurisdiction for the appointment of a successor
Trustee with respect to the Securities of such series.

     (f) The Company shall give notice of each resignation and each removal of the Trustee
with respect to the Securities of any series and each appointment of a successor Trustee
with respect to the Securities of any series to all Holders of Securities of such series in
the manner provided in Section 1.7. Each notice shall include the name of the successor
Trustee with respect to the Securities of such series and the address of its Corporate Trust
Office.

Section 6.11. Acceptance of Appointment by Successor.

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

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

     (c) Upon request of any such successor Trustee, the Company and, if applicable, the
Guarantors shall execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred to in
paragraph (a) or (b) of this Section, as the case may be.

     (d) No successor Trustee shall accept its appointment unless at the time of such
acceptance such successor Trustee shall be qualified and eligible under this Article and the
Trust Indenture Act.

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

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

Section 6.13. Preferential Collection of Claims Against Company.

     Reference is made to Section 311 of the Trust Indenture Act. For purposes of Section 311(b)
of the Trust Indenture Act:

     (a) the term “cash transaction” means any transaction in which full payment for goods
or securities sold is made within seven days after delivery of the goods or securities in
currency or in checks or other orders drawn upon banks or bankers and payable upon demand;

     (b) the term “self-liquidating paper” means any draft, bill of exchange, acceptance or
obligation which is made, drawn, negotiated or incurred by the Company or, if applicable,
any Guarantor for the purpose of financing the purchase, processing, manufacturing,
shipment, storage or sale of goods, wares or merchandise and which is secured by documents
evidencing title to, possession of, or a lien upon, the goods, wares or merchandise or the
receivables or proceeds arising from the sale of the goods, wares or merchandise previously
constituting the security, provided the security is received by the Trustee simultaneously
with the creation of the creditor relationship with the Company or, if applicable, such
Guarantor arising from the making, drawing, negotiating or incurring of the draft, bill of
exchange, acceptance or obligation.

Section 6.14. Appointment of Authenticating Agent.

     The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series
of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities
of such series issued upon exchange, registration of transfer or partial redemption thereof or
pursuant to Section 3.6, and Securities so authenticated shall be entitled to the benefits of this
Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee
hereunder. Wherever reference is made in this Indenture to the authentication and delivery of
Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent shall be acceptable to the Company and shall at all times be a
corporation organized and doing business under the laws of the United States of America, any State
thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent,
having a combined capital and surplus of not less than $50,000,000 and subject to supervision or
examination by Federal or State authority. If such Authenticating Agent publishes reports of
condition at least annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital and surplus of
such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. If at any time an Authenticating Agent shall
cease to be eligible in accordance

47

 

with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner
and with the effect specified in this Section.

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

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

     The Company agrees to pay to each Authenticating Agent from time to time reasonable
compensation for its services under this Section 6.14.

     If an appointment with respect to one or more series is made pursuant to this Section 6.14,
the Securities of such series may have endorsed thereon, in addition to the Trustee’s certificate
of authentication, an alternate certificate of authentication in the following form:

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

to Section 13 or Section 15(d) of the Exchange Act; or, if the Company is not required to
file information, documents or reports pursuant to either of said Sections, then it shall
file with the Trustee and the SEC, in accordance with rules and regulations prescribed from
time to time by the SEC, such of the supplementary and periodic information, documents and

clauses (a) and (b) of this Section as may be required by rules and regulations prescribed
from time to time by the SEC.

Delivery of such reports, information and documents to the Trustee shall be for informational
purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any
information contained therein or determinable from information contained therein, including the
Company’s compliance with any of the covenants contained in the Indenture (as to which the Trustee
will be entitled to conclusively rely upon an Officer’s Certificate).

     Upon the request of the Company accompanied by a Board Resolution authorizing the execution of

described in Section 6.3 hereof, the Trustee will join with the Company and any Guarantor in the
execution of any such amendment or supplemental indenture, to make any further appropriate
agreements and stipulations that may be therein contained and to accept the conveyance, transfer,
assignment, mortgage, charge or pledge of any property thereunder, but the Trustee shall not be
obligated to enter into

52

 

any such amendment or supplemental indenture that affects the Trustee’s own rights, duties or
immunities under this Indenture or otherwise.

Section 9.2.
With Consent of Holders.

     The Company and the Trustee may amend or supplement this Indenture, the Securities Guarantees
and the Securities with the consent of the Holders of a majority in aggregate principal amount of
the Outstanding Securities of each series of Securities affected by such amendment or supplemental
indenture, with each such series voting as a separate class (including, without limitation,
consents obtained in connection with a purchase of, or tender offer or exchange offer for,
Securities) and, subject to Section 5.8 and Section 5.13 hereof, any existing Default or Event of
Default or compliance with any provision of this Indenture, the Securities Guarantees or the
Securities may be waived with respect to each series of Securities with the consent of the Holders
of a majority in principal amount of the Outstanding Securities of such series voting as a separate
class (including consents obtained in connection with a purchase of, or tender offer or exchange
offer for, Securities).

     Upon the request of the Company accompanied by a Board Resolution authorizing the execution of
any such amendment or supplemental indenture, and upon the filing with the Trustee of evidence
satisfactory to the Trustee of the consent of the Holders of Securities as aforesaid, and upon
receipt by the Trustee of the documents described in Section 6.3 hereof, the Trustee will join with
the Company and the Guarantors in the execution of such amendment or supplemental indenture unless
such amendment or supplemental indenture directly affects the Trustee’s own rights, duties or
immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but
will not be obligated to, enter into such amendment or supplemental Indenture.

     It is not necessary for the consent of the Holders of Securities under this Section 9.2 to
approve the particular form of any proposed amendment, supplement or waiver, but it is sufficient
if such consent approves the substance of the proposed amendment, supplement or waiver.

     After an amendment, supplement or waiver under this Section 9.2 becomes effective, the Company
will mail to the Holders of Securities affected thereby a notice briefly describing the amendment,
supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, will
not, however, in any way impair or affect the validity of any such amendment, supplemental
indenture or waiver. Subject to Section 5.8 and Section 5.13 hereof, the application of or
compliance with, either generally or in any particular instance, of any provision of this
Indenture, the Securities or the Securities Guarantees may be waived as to each series of
Securities by the Holders of a majority in aggregate principal amount of the Outstanding Securities
of such series voting as a separate class (including consents obtained in connection with a
purchase of, or tender offer or exchange offer for, Securities). However, without the consent of
each Holder affected, an amendment, supplement or waiver under this Section 9.2 may not (with
respect to any Securities held by a non-consenting Holder):

     (a) change the Stated Maturity of the principal of, or any installment of principal of
or interest on, any Security, or reduce the principal amount thereof or the rate of interest
thereon or any premium payable upon the redemption thereof, 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 5.2, or change the
coin or currency in which any Security or any premium or the interest thereon is payable, or
impair the right to institute suit for the enforcement of any such payment on or after the
Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date); or

53

 

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

     (c) modify any of the provisions of Section 5.8 or Section 5.13; or

     (d) waive a redemption payment with respect to any Security; provided, however, that
any purchase or repurchase of Securities shall not be deemed a redemption of the Securities;
or

     (e) release any Guarantor from any of its obligations under its Securities Guarantee or
this Indenture, except in accordance with the terms of this Indenture (as amended or
supplemented); or

     (f) make any change in the foregoing amendment and waiver provisions, except to
increase any percentage provided for therein or to provide that certain other provisions of
this Indenture cannot be modified or waived without the consent of the Holder of each
Outstanding Security affected thereby.

     An amendment or supplemental indenture that changes or eliminates any covenant or other
provision of this Indenture that has expressly been included solely for the benefit of one or more
particular series of Securities, or that 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.

Section 9.3.
Execution of Amendments and Supplemental Indentures.

     In executing, or accepting the additional trusts created by, any amendment or supplemental
indenture permitted by this Article or the modifications thereby of the trusts created by this
Indenture, in addition to the documents required by Section 1.3, the Trustee shall be entitled to
receive, and (subject to Section 6.1) shall be fully protected in relying upon, an Opinion of
Counsel stating that the execution of such amendment or supplemental indenture is authorized or
permitted by this Indenture. The Trustee may, but shall not be obligated to, enter into any such

modified as to conform, in the opinion of the Trustee and the Company, to any such amendment or
supplemental indenture may be prepared and executed by the Company and authenticated and delivered
by the Trustee in exchange for Outstanding Securities of such series.

ARTICLE TEN

COVENANTS

Section 10.1.
Payment of Principal, Premium and Interest.

     The Company covenants and agrees for the benefit of each series of Securities that it will
duly and punctually pay the principal of and any premium and interest on the Securities of that
series in accordance with the terms of the Securities and this Indenture.

Section 10.2.
Maintenance of Office or Agency.

     The Company will maintain in the United States an office or agency (which may be an office of
the Trustee or Registrar or agent of the Trustee or Registrar) where Securities of each series may
be presented or surrendered for payment and surrendered for registration of transfer or exchange
and where notices and demands to or upon the Company in respect of the Securities of that series
and this Indenture may be served. The Company will give prompt written notice to the Trustee of
the location, and any change in the location, of such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with
the address thereof, such presentations, surrenders, notices and demands may be made or served at
the Corporate Trust Office of the Trustee.

     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. 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.

     Except as otherwise specified with respect to a series of Securities as contemplated by
Section 3.1, the Company hereby initially designates the office of the Trustee located at 601
Travis Street, 16th Floor, Houston, Texas 77002, as the Company’s office or agency for
each such purpose for each series of Securities.

Section 10.3.
Money for Securities Payments to Be Held in Trust.

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

55

 

     Whenever the Company shall have one or more Paying Agents for any series of Securities, it
will, prior to each due date of the principal of and any premium or interest on any Securities of
that series, deposit with a Paying Agent a sum sufficient to pay the principal and any premium or
interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to
such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of its action or failure so to act. For purposes of this Section 10.3,
should a due date for principal of and any premium or interest on, or sinking fund payment with
respect to any series of Securities not be on a Business Day, such payment shall be due on the next
Business Day without any interest for the period from the due date until such Business Day.

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

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

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

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

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

     Subject to any applicable escheat or abandoned property laws, any money deposited with the
Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal
of and any premium or interest on any Security of any series and remaining unclaimed for one year
after such principal, premium or interest has become due and payable shall be paid to the Company
on Company Request, or (if then held by the Company) shall be discharged from such trust; and the
Holder of such Security shall thereafter, as an unsecured general creditor, look only to the
Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to
such trust money, and all liability of the Company as trustee thereof, shall thereupon cease;
provided, however, that the Trustee or such Paying Agent, before being required to make any such
repayment, may at the expense of the Company cause to be published once, in The New York Times and
The Wall Street Journal (national edition), notice that such money remains unclaimed and that,
after a date specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be repaid to the Company.

Section 10.4.
Existence.

     Subject to Article Eight, the Company and, if any Securities of a series to which Article
Fourteen has been made applicable are Outstanding, each Guarantor will do or cause to be done all
things necessary to preserve and keep in full force and effect its existence, rights (charter and
statutory) and

56

 

franchises; provided, however, that the Company and, if applicable, each Guarantor shall not
be required to preserve any such right or franchise if the Board of Directors shall determine that
the preservation thereof is no longer desirable in the conduct of the business of the Company or
such Guarantor, as the case may be.

Section 10.5.
Statement by Officers as to Default.

     Annually, within 150 days after the close of each fiscal year beginning with the first fiscal
year during which one or more series of Securities are Outstanding, the Company and, if any
Securities of a series to which Article Fourteen has been made applicable are Outstanding, each
Guarantor will deliver to the Trustee a brief certificate (which need not include the statements
set forth in Section 1.3) from the principal executive officer, principal financial officer or
principal accounting officer of the Company and, if applicable, such Guarantor as to his or her
knowledge of the Company’s or such Guarantor’s, as the case may be, compliance (without regard to
any period of grace or requirement of notice provided herein) with all conditions and covenants
under this Indenture and, if the Company or such Guarantor, as the case may be, shall be in
Default, specifying all such Defaults and the nature and status thereof of which such officer has
knowledge.

ARTICLE ELEVEN

REDEMPTION OF SECURITIES

Section 11.1.
Applicability of Article.

     Securities of any series which are redeemable before their Stated Maturity shall be redeemable
in accordance with their terms and (except as otherwise specified as contemplated by Section 3.1
for Securities of any series) in accordance with this Article Eleven.

Section 11.2.
Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Securities shall be evidenced by a Board Resolution.
In case of any redemption at the election of the Company of less than all the Securities of any
series, the Company shall, at least 15 days prior to the last date for the giving of notice of such
redemption (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of
such Redemption Date and of the principal amount of Securities of such series to be redeemed and,
if applicable, of the tenor of the Securities to be redeemed. In the case of any redemption of
Securities (a) prior to the expiration of any restriction on such redemption provided in the terms
of such Securities or elsewhere in this Indenture or (b) pursuant to an election of the Company
that is subject to a condition specified in the terms of the Securities of the series to be
redeemed, the Company shall furnish the Trustee with an Officer’s Certificate evidencing compliance
with such restriction or condition.

Section 11.3.
Selection by Trustee 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 and of a specified tenor are to be redeemed), the particular Securities to be
redeemed shall be selected not more than 45 days prior to the Redemption Date by the Trustee, from
the Outstanding Securities of such series not previously called for redemption, by such method as
the Trustee shall deem fair and appropriate and which 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.

57

 

     The Trustee shall promptly notify the Company 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. If the Securities of any series to be redeemed consist of Securities
having different dates on which the principal is payable or different rates of interest, or
different methods by which interest may be determined or have any other different tenor or terms,
then the Company may, by written notice to the Trustee, direct that the Securities of such series
to be redeemed shall be selected from among the groups of such Securities having specified tenor or
terms and the Trustee shall thereafter select the particular Securities to be redeemed in the
manner set forth in the preceding paragraph from among the group of such Securities so specified.

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

Section 11.4.
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 his address appearing in the Security Register.

     All notices of redemption shall state:

     (a) the Redemption Date;

     (b) the Redemption Price, or if not then ascertainable, the manner of calculation
thereof;

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

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

     (e) the place or places where such Securities are to be surrendered for payment of the
Redemption Price;

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

     (g) the CUSIP number, if any, listed in the notice or printed on the Notes, and that no
representation is made as to the accuracy or correctness of such CUSIP number.

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

Section 11.5.
Deposit of Redemption Price.

     At least one Business Day prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and
hold in trust as provided in Section 10.3) an amount of money sufficient to pay the Redemption
Price of, and

58

 

(except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the
Securities which are to be redeemed on that date.

Section 11.6.
Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall,
on the Redemption Date, become due and payable at the Redemption Price therein specified, and from
and after such date (unless the Company shall default in the payment of the Redemption Price and
accrued interest) such Securities shall cease to bear interest. Upon surrender of any such
Security for redemption in accordance with said notice, such Security shall be paid by the Company
at the Redemption Price, together with accrued interest to the Redemption Date; provided, however,
that unless otherwise specified with respect to Securities of any series as contemplated in Section
3.1, installments of interest the Stated Maturity of which is on or prior to the Redemption Date
shall be payable to the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the relevant record dates according to their terms
and the provisions of Section 3.7.

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

Section 11.7.
Securities Redeemed in Part.

     Any Security which is to be redeemed only in part shall be surrendered at a Place of Payment
therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the
Holder thereof or his attorney duly authorized in writing), and the Company shall execute, 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 tenor, of any authorized denomination as requested by
such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of
the principal of the Security so surrendered.

ARTICLE TWELVE

SINKING FUNDS

Section 12.1.
Applicability of Article.

     The provisions of this Article Twelve shall be applicable to any sinking fund for the
retirement of Securities of a series except as otherwise specified as contemplated by Section 3.1
for Securities of such series.

     The minimum amount of any sinking fund payment provided for by the terms of Securities of any
series is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of
such minimum amount provided for by the terms of Securities of any series is herein referred to as
an “optional sinking fund payment.” If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided in Section 12.2.
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.

59

 

Section 12.2.
Satisfaction of Sinking Fund Payments with Securities.

     The Company (a) may deliver Outstanding Securities of a series (other than any previously
called for redemption) and (b) may apply as a credit Securities of a series which have been
redeemed either at the election of the Company pursuant to the terms of such Securities or through
the application of permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund payment with
respect to the Securities of such series required to be made pursuant to the terms of such
Securities as provided for by the terms of such series; 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 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 12.3.
Redemption of Securities for Sinking Fund.

     Not less than 45 days prior to each sinking fund payment date for any series of Securities
(unless a shorter period shall be satisfactory to the Trustee), the Company will deliver to the
Trustee an Officer’s Certificate 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
delivering and crediting Securities of that series pursuant to Section 12.2 and stating the basis
for such credit and that such Securities have not been previously so credited, and will also
deliver to the Trustee any Securities to be so delivered. 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 11.3 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 11.4. Such notice having been duly given, the redemption of such Securities shall be made
upon the terms and in the manner stated in Section 11.6 and Section 11.7.

ARTICLE THIRTEEN

DEFEASANCE

Section 13.1.
Option to Effect Legal Defeasance or Covenant Defeasance.

     The Company may, at the option of its Board of Directors evidenced by a Board Resolution, and
at any time, elect to have either Section 13.2 or Section 13.3 hereof be applied to all outstanding
Securities upon compliance with the conditions set forth below in this Article Thirteen.

Section 13.2.
Legal Defeasance and Discharge.

     Upon the Company’s exercise under Section 13.1 hereof of the option applicable to this Section
13.2, the Company and each of the Guarantors will, subject to the satisfaction of the conditions
set forth in Section 13.4 hereof, be deemed to have been discharged from their obligations with
respect to all outstanding Securities (including the Securities Guarantees) on the date the
conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose,
Legal Defeasance means that the Company and the Guarantors will be deemed to have paid and
discharged the entire Debt represented by the outstanding Securities (including the Securities
Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section
13.5 hereof and the other sections of this Indenture referred to in clauses (a) and (b) below, and
to have satisfied all their other obligations under such Securities, the Securities Guarantees and
this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute
proper instruments acknowledging the same), except for the following provisions which will survive
until otherwise terminated or discharged hereunder:

60

 

     (a) the rights of Holders of Outstanding Securities to receive payments in respect of
the principal of, or interest or premium, if any, on, such Securities when such payments are
due from the trust referred to in Section 13.4 hereof;

     (b) the Company’s obligations with respect to such Securities under Section 3.4,
Section 3.5, Section 3.6, Section 10.2 and Section 10.3 hereof;

     (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the
Company’s and the Guarantors’ obligations in connection therewith; and

     (d) this Article Thirteen.

     Subject to compliance with this Article Thirteen, the Company may exercise its option under
this Section 13.2 notwithstanding the prior exercise of its option under Section 13.3 hereof.

Section 13.3.
Covenant Defeasance.

     Upon the Company’s exercise under Section 13.1 hereof of the option applicable to this Section
13.3, the Company and each of the Guarantors will, subject to the satisfaction of the conditions
set forth in Section 13.4 hereof, be released from each of their obligations under the covenants
contained in Section 7.4, Section 8.1 and Section 10.4 hereof as well as any Additional Defeasible
Provisions (such release and termination hereinafter referred to as “Covenant Defeasance”), and the
Securities will thereafter be deemed not “outstanding” for the purposes of any direction, waiver,
consent or declaration or act of Holders (and the consequences of any thereof) in connection with
such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it
being understood that such Securities will not be deemed outstanding for accounting purposes). For
this purpose, Covenant Defeasance means that, with respect to the outstanding Securities and
Securities Guarantees, the Company and the Guarantors may fail to comply with and will have no
liability in respect of any term, condition or limitation set forth in any such covenant, whether
directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by
reason of any reference in any such covenant to any other provision herein or in any other document
and such failure to comply will not constitute a Default or an Event of Default under Section 5.1
hereof, but, except as specified above, the remainder of this Indenture and such Securities and
Securities Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under
Section 13.1 hereof of the option applicable to this Section 13.3 hereof, subject to the
satisfaction of the conditions set forth in Section 13.4 hereof, any Event of Default that
constitutes an Additional Defeasible Provision will no longer constitute an Event of Default.

Section 13.4.
Conditions to Legal or Covenant Defeasance.

     In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 13.2
or Section 13.3 hereof:

     (a) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of
the Holders of the Securities, cash in U.S. dollars, non-callable U.S. Government
Obligations, or a combination of cash in U.S. dollars and non-callable U.S. Government
Obligations, in such amounts as will be sufficient, in the opinion of a nationally
recognized investment bank, appraisal firm, or firm of independent public accountants, to
pay the principal of, and interest and premium, if any, on, the Outstanding Securities on
the stated date for payment thereof or on the applicable redemption date, as the case may
be, and the Company must specify whether the Securities are being defeased to such stated
date for payment or to a particular redemption date;

61

 

     (b) in the case of an election under Section 13.2 hereof, the Company must deliver to
the Trustee an Opinion of Counsel confirming that:

     (i) the Company has received from, or there has been published by, the Internal
Revenue Service a ruling; or

     (ii) since the Issue Date, there has been a change in the applicable federal
income tax law,

in either case to the effect that, and based thereon such Opinion of Counsel will
confirm that, the Holders of the Outstanding Securities will not recognize income,
gain or loss for federal income tax purposes as a result of such Legal Defeasance
and will be subject to federal income tax on the same amounts, in the same manner
and at the same times as would have been the case if such Legal Defeasance had not
occurred;

     (c) in the case of an election under Section 13.3 hereof, the Company must deliver to
the Trustee an Opinion of Counsel confirming that the Holders of the Outstanding Securities
will not recognize income, gain or loss for federal income tax purposes as a result of such
Covenant Defeasance and will be subject to federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such Covenant Defeasance
had not occurred;

     (d) no Default or Event of Default shall have occurred and be continuing on the date of
such deposit (other than a Default or Event of Default resulting from the borrowing of funds
to be applied to such deposit);

     (e) the deposit must not result in a breach or violation of, or constitute a default
under, any other instrument to which the Company or any Guarantor is a party or by which the
Company or any Guarantor is bound;

     (f) such Legal Defeasance or Covenant Defeasance must not result in a breach or
violation of, or constitute a default under, any material agreement or instrument (other
than this Indenture) to which the Company or any of its Subsidiaries is a party or by which
the Company or any of its Subsidiaries is bound;

     (g) the Company must deliver to the Trustee an Officer’s Certificate stating that the
deposit was not made by the Company with the intent of preferring the Holders of Securities
over the other creditors of the Company with the intent of defeating, hindering, delaying or
defrauding any other creditors of the Company or others;

     (h) the Company must deliver to the Trustee an Officer’s Certificate stating that all
conditions precedent set forth in clauses (a) through (f) of this Section 13.4 have been
complied with; and

     (i) the Company must deliver to the Trustee an Opinion of Counsel (which Opinion of
Counsel may be subject to customary assumptions, qualifications and exclusions) stating that
all conditions precedent set forth in clauses (b), (c) and (f) of this Section 13.4 have
been complied with.

62

 

Section 13.5.
Deposited Money and U.S. Government Obligations to be Held in Trust, Other Miscellaneous
Provisions.

     Subject to Section 13.6 hereof, all money and non-callable U.S. Government Obligations
(including the proceeds thereof) deposited with the Trustee (or other qualifying trustee,
collectively for purposes of this Section 13.5, the “Trustee”) pursuant to Section 13.4 hereof in
respect of the Outstanding Securities will be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee
may determine, to the Holders of such Securities of all sums due and to become due thereon in
respect of principal, premium, if any, and interest, but such money need not be segregated from
other funds except to the extent required by law.

     The Company will pay and indemnify the Trustee against any tax, fee or other charge imposed on
or assessed against the cash or non-callable U.S. Government Obligations deposited pursuant to
Section 13.4 hereof or the principal and interest received in respect thereof other than any such
tax, fee or other charge which by law is for the account of the Holders of the Outstanding
Securities.

     Notwithstanding anything in this Article Thirteen to the contrary, the Trustee will deliver or
pay to the Company from time to time upon the request of the Company any money or non-callable U.S.
Government Obligations held by it as provided in Section 13.4 hereof which, in the opinion of a
nationally recognized investment bank, appraisal firm or firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee (which may be the opinion
delivered under Section 13.4(a) hereof), are in excess of the amount thereof that would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 13.6.
Repayment.

     Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of or premium, if any, or interest on any Security and
remaining unclaimed for two years after such principal, premium, if any, or interest has become due
and payable shall be paid to the Company on its request or (if then held by the Company) will be
discharged from such trust; and the Holder of such Security will thereafter be permitted to look
only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee thereof, will thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being required to make any
such repayment, may at the expense of the Company cause to be published once, in The New York Times
and The Wall Street Journal (national edition), notice that such money remains unclaimed and that,
after a date specified therein, which will not be less than 30 days from the date of such
notification or publication, any unclaimed balance of such money then remaining will be repaid to
the Company.

Section 13.7.
Reinstatement.

     If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable
U.S. Government Obligations in accordance with Section 13.2 or Section 13.3 hereof, as the case may
be, by reason of any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, then the Company’s and the Guarantors’
obligations under this Indenture and the Securities and the Securities Guarantees will be revived
and reinstated as though no deposit had occurred pursuant to Section 13.2 or Section 13.3 hereof
until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance
with Section 13.2 or Section 13.3 hereof, as the case may be; provided, however, that, if the
Company makes any payment of principal of or premium, if any, or interest on any Note following the
reinstatement of its obligations, the Company will

63

 

be subrogated to the rights of the Holders of such Securities to receive such payment from the
money held by the Trustee or Paying Agent.

ARTICLE FOURTEEN

GUARANTEE OF SECURITIES

Section 14.1.
Securities Guarantee.

     (a) Subject to the other provisions of this Article Fourteen, each of the Guarantors
hereby jointly and severally guarantees to each Holder of a Security of each series to which
this Article Fourteen has been made applicable as provided in Section 3.1(t) (the Securities
of such series being referred to herein as the “Guaranteed Securities”) (which Security has
been authenticated and delivered by the Trustee), and to the Trustee and its successors and
assigns, irrespective of the validity and enforceability of this Indenture, the Guaranteed
Securities, or the obligations of the Company hereunder or thereunder, that:

     (i) the principal of and premium, if any, and interest on the Guaranteed
Securities will be promptly paid in full when due, whether at maturity, or by
acceleration, redemption or otherwise, and interest on the overdue principal of and
interest on the Guaranteed Securities, if any, if lawful, and all other obligations
of the Company to the Holders of Guaranteed Securities, or the Trustee hereunder or
thereunder, will be promptly paid in full or performed, all in accordance with the
terms hereof and thereof; and

     (ii) in case of any extension of time of payment or renewal of any Guaranteed
Securities or any of such other obligations, that same will be promptly paid in full
when due or performed in accordance with the terms of the extension or renewal,
whether at stated maturity, by acceleration or otherwise.

Failing payment when due of any amount so guaranteed or any performance so guaranteed for
whatever reason, the Guarantors will be jointly and severally obligated to pay the same
immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee
of collection.

     (b) To the extent permissible under applicable law, the obligations of the Guarantors
under this Securities Guarantee are unconditional, irrespective of the validity, regularity
or enforceability of the Guaranteed Securities or this Indenture, the absence of any action
to enforce the same, any waiver or consent by any Holder of the Guaranteed Securities with
respect to any provisions hereof or thereof, the recovery of any judgment against the
Company, any action to enforce the same or any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor. To the extent
permitted by applicable law, each Guarantor hereby waives diligence, presentment, demand of
payment, filing of claims with a court in the event of insolvency or bankruptcy of the
Company, any right to require a proceeding first against the Company, protest, notice and
all demands whatsoever and covenants that this Securities Guarantee will not be discharged
except by complete performance of the obligations contained in the Guaranteed Securities and
this Indenture.

     (c) If any Holder or the Trustee is required by any court or otherwise to return to the
Company, the Guarantors or any custodian, trustee, liquidator or other similar official
acting in relation to either the Company or the Guarantors, any amount paid by either to the
Trustee or

64

 

such Holder, this Securities Guarantee, to the extent theretofore discharged, will be
reinstated in full force and effect.

     (d) Each Guarantor agrees that it will not be entitled to any right of subrogation in
relation to the Holders in respect of any obligations guaranteed hereby until payment in
full of all obligations guaranteed hereby. Each Guarantor further agrees that, to the
extent permitted by applicable law, as between the Guarantors, on the one hand, and the
Holders of Guaranteed Securities and the Trustee, on the other hand, (i) the maturity of the
obligations guaranteed hereby may be accelerated as provided in Article Five hereof for the
purposes of this Securities Guarantee, notwithstanding any stay, injunction or other
prohibition preventing such acceleration in respect of the obligations guaranteed hereby,
and (ii) in the event of any declaration of acceleration of such obligations as provided in
Article Five hereof, such obligations (regardless of whether due and payable) will forthwith
become due and payable by the Guarantors for the purpose of this Securities Guarantee. The
Guarantors will have the right to seek contribution from any non-paying Guarantor so long as
the exercise of such right does not impair the rights of the Holders under the Securities
Guarantee.

Section 14.2.
Limitation on Guarantor Liability.

     Each Guarantor, and by its acceptance of Guaranteed Securities, each Holder thereof, hereby
confirms that it is the intention of all such parties that the Securities Guarantee of such
Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the
Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar Federal or
State law to the extent applicable to any Securities Guarantee. To effectuate the foregoing
intention, the Trustee, to the extent permitted under applicable law, the Holders and each
Guarantor hereby irrevocably agree that the obligations of such Guarantor will be limited to the
maximum amount that will, after giving effect to such maximum amount and all other contingent and
fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to
any collections from, rights to receive contribution from or payments made by or on behalf of any
other Guarantor in respect of the obligations of such other Guarantor under this Article Fourteen,
result in the obligations of such Guarantor under its Securities Guarantee not constituting a
fraudulent transfer or conveyance.

Section 14.3.
Execution and Delivery of Securities Guarantee Notation.

     To evidence its Securities Guarantee set forth in Section 14.1 hereof, each Guarantor hereby
agrees that a notation of such Securities Guarantee substantially in the form set forth in Section
2.3 or established in or pursuant to a Board Resolution or in an indenture supplemental hereto, in
accordance with the provisions of Section 2.1, will be endorsed by an officer of such Guarantor on
each Guaranteed Security authenticated and delivered by the Trustee and that this Indenture will be
executed on behalf of such Guarantor by one of its officers.

     Each Guarantor hereby agrees that its Securities Guarantee set forth in Section 14.1 hereof
will remain in full force and effect notwithstanding any failure to endorse on each Guaranteed
Security a notation of such Securities Guarantee.

     If an officer whose signature is on this Indenture or on the Securities Guarantee no longer
holds that office at the time the Trustee authenticates the Guaranteed Security on which a
Securities Guarantee is endorsed, the Securities Guarantee will be valid nevertheless.

65

 

     The delivery of any Guaranteed Security by the Trustee, after the authentication thereof
hereunder, will constitute due delivery of the Securities Guarantee of such Guaranteed Security set
forth in this Indenture on behalf of the Guarantors.

Supplemental Indenture.

 

 

     THIS FIRST SUPPLEMENTAL INDENTURE, dated as of March 4, 2011, is among Key Energy
Services, Inc., a Maryland corporation (the “Company”), each of the Guarantors (as defined herein)
and The Bank of New York Mellon Trust Company, N.A., a national banking association, as trustee
(the “Trustee”).

     WHEREAS, the Company has duly authorized, executed and delivered the Base Indenture to provide
for the issuance from time to time of the Company’s debentures, notes or other evidences of
indebtedness, to be issued in one or more series, and the Guarantee by each of the Subsidiary
Guarantors of the Securities, as the Base Indenture provides;

     WHEREAS, Section 9.1 of the Base Indenture provides, among other things, that the Company, the
Subsidiary Guarantors and the Trustee may enter into indentures supplemental to the Base Indenture,
without the consent of any Holders of Securities, to establish the form or terms of any Security as
permitted by Sections 201 and 301 of the Base Indenture;

     WHEREAS, pursuant to Sections 2.1 and 3.1 of the Base Indenture, the Company desires to
execute this Supplemental Indenture to establish the form and terms, and to provide for the
issuance, of a series of senior notes designated as 6.750% Senior Notes due 2021 in an aggregate
principal amount of $475,000,000 (the “Initial Securities”);

     WHEREAS, from time to time subsequent to the Issue Date, the Company may, if permitted to do
so pursuant to the terms of the Indenture, the Initial Notes and the terms of its other
indebtedness existing on such future date, issue additional senior notes of the same series as the
Initial Notes in accordance with this Supplemental Indenture (the “Additional Securities” and,
together with the Initial Notes, the “Securities”), pursuant to this Supplemental Indenture;

     WHEREAS, the Company and the Subsidiary Guarantors are members of the same consolidated group
of companies; the Subsidiary Guarantors will derive direct and indirect economic benefit from the
issuance of the Securities; and accordingly, each Subsidiary Guarantor has duly authorized the
execution and delivery of this Supplemental Indenture to provide for its full, unconditional and
joint and several Guarantee of the Notes to the extent provided in or pursuant to the Indenture;

     WHEREAS, this Supplemental Indenture is subject to the provisions of the Trust Indenture Act
of 1939, as amended, that are required to be a part of this Supplemental Indenture and shall, to
the extent applicable, be governed by such provisions;

     WHEREAS, this Supplemental Indenture restates in their entirety the terms of the Base
Indenture as supplemented by the Supplemental Indenture and does not incorporate the terms of the
Base Indenture. The changes, modifications and supplements to the Base Indenture affected by this
Supplemental Indenture shall be applicable only with respect to, and shall only govern the terms
of, the Securities, except as otherwise provided herein, and shall not apply to any other
securities that may be issued under the Base Indenture unless a supplemental indenture with respect
to such other securities specifically incorporates such changes, modifications and supplements; and

     WHEREAS, All things necessary have been done to make the Notes, when executed by the Company
and authenticated and delivered hereunder and duly issued by the Company, the valid obligations of
the Company, and all things necessary have been done to make the Subsidiary Guarantees thereof,
when the Notes have been executed by the Company and authenticated and delivered hereunder and duly
issued by the Company, the valid obligations of the Subsidiary Guarantors. All things necessary to
make this Supplemental Indenture a valid agreement of each of the Company and the Subsidiary
Guarantors, in accordance with its terms, have been done;

     NOW THEREFORE, the Company, the Guarantors and the Trustee agree as follows for the benefit of
each other and for the equal and ratable benefit of the Holders (as hereinafter defined) of the
Securities:

ARTICLE 2

THE SECURITIES

Section 2.01 Form and Dating

     (a) General. The Securities and the Trustee’s certificate of authentication shall be
substantially in the form of Exhibit A hereto. Any notation of Subsidiary Guarantee shall be
substantially in the form of Exhibit D hereto, and shall be notated on the Securities. The
Securities may have notations, legends or endorsements required by law, stock exchange rule or
usage. Each Security shall be dated the date of its authentication. The Securities shall be in
minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The terms and
provisions contained in the Securities shall constitute, and are hereby expressly made, a part of
this Supplemental Indenture and the Company, the Guarantors and the Trustee, by their execution and
delivery of this Supplemental Indenture, expressly agree to such terms and provisions and to be
bound thereby. However, to the extent any provision of any Security or any Subsidiary Guarantee
conflicts with the express provisions of this Supplemental Indenture, the provisions of this
Supplemental Indenture (to the extent permitted by law) shall govern and be controlling.

     (b) Global Securities. Securities issued in global form shall be substantially in the form of
Exhibit A attached hereto (including the Global Security Legend thereon and the “Schedule
of Exchanges of Interests in the Global Security” attached thereto). Securities issued in
definitive form shall be substantially in the form of Exhibit A attached hereto (but
without the Global Security Legend thereon and without the “Schedule of Exchanges of Interests in
the Global Security” attached thereto). Each Global Security shall represent such of the
outstanding Securities as shall be specified therein, and each shall provide that it shall
represent the aggregate principal amount of outstanding Securities from time to time endorsed
thereon and that the aggregate principal amount of outstanding Securities represented thereby may
from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions.
Any endorsement of a Global Security to reflect the amount of any increase or decrease in the
aggregate principal amount of outstanding Securities represented thereby shall be made by the
Trustee or the Securities Custodian, at the direction of the Trustee, in accordance with
instructions given by the Holder thereof as required by Section 2.06 hereof.

     (c) Definitive Securities. Notwithstanding any other provision of this Article II,
any issuance of Definitive Securities shall be at the Company’s discretion, except in the specific
circumstances set forth in Section 2.06(a) hereof.

Section 2.02 Execution and Authentication

     (a) An Officer shall sign the Securities for the Company by manual or facsimile signature.
One Officer shall sign each notation of Subsidiary Guarantee for each Guarantor by manual or
facsimile signature.

27

 

     (b) If an Officer whose facsimile signature is on a Security no longer holds that office at
the time the Trustee authenticates the Security, the Security shall be valid nevertheless.

     (c) A Security shall not be valid until an authorized signatory of the Trustee manually
authenticates the Security. The signature of the Trustee on a Security shall be conclusive
evidence that such Security has been duly and validly authenticated and issued under this
Supplemental Indenture.

     (d) The Trustee shall authenticate and deliver: (1) Initial Securities for original issue in
an aggregate principal amount of $475,000,000 and (2) if and when issued, Additional Securities
(which may be issued in either a registered or a private offering under the Securities Act), in
each case upon a written order of the Company signed by one Officer of the Company. Such order
shall specify the amount of the Securities to be authenticated and the date on which the issue of
Securities is to be authenticated and whether the Securities are to be in global or definitive
form. The Trustee shall also be entitled to receive, and (subject to Section 7.01) shall be fully
protected in relying upon, in addition to the documents required by Section 11.04, an Opinion of
Counsel stating: that such Initial Securities when authenticated and delivered by the Trustee and
issued by the Company in the manner and subject to any conditions and assumptions specified in such
Opinion of Counsel, will constitute valid and legally binding obligations of the Company and, if
applicable, the Guarantors, enforceable in accordance with their terms, subject to the following
limitations: (i) bankruptcy, insolvency, moratorium, reorganization, liquidation, fraudulent
conveyance or transfer and other similar laws of general applicability relating to or affecting the
enforcement of creditors’ rights, or to general equity principles, (ii) the availability of
equitable remedies being subject to the discretion of the court to which application therefor is
made; and (iii) such other usual and customary matters as shall be specified in such Opinion of
Counsel. The Company may issue Additional Securities under this Supplemental Indenture subsequent
to the Issue Date, subject to Section 4.03 of this Supplemental Indenture; provided,
however, that no Additional Securities may be issued at a price that would cause such Additional
Securities to have “original issue discount” within the meaning of Section 1273 of the Code.

     (e) The Trustee shall have the right to decline to authenticate and deliver any Additional
Securities under this Section if the Trustee determines that such action may not lawfully be taken
by the Company or if the Trustee in good faith by its board of directors or board of trustee,
executive committee, or a trust committee of directors or trustees or Trust Officers shall
determine that such action would expose the Trustee to personal liability to existing Holders.

     (f) The Trustee may appoint an agent (the “Authenticating Agent”) reasonably acceptable to the
Company to authenticate the Securities. Unless limited by the terms of such appointment, any such
Authenticating Agent may authenticate Securities whenever the Trustee may do so. Each reference in
this Supplemental Indenture to authentication by the Trustee includes authentication by such agent.

Section 2.03 Registrar and Paying Agent

     (a) The Company shall at all times maintain in the continental United States an office or
agency where Securities may be presented for registration of transfer or for exchange (the
“Registrar”), and it shall likewise maintain an office or agency where Securities may be presented
for payment (the “Paying Agent”). The Registrar shall keep a register of the Securities and of
their transfer and exchange. The Company may have 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 such additional paying agent.

     (b) The Company or any of its Subsidiaries may act as Paying Agent, subject to the provisions
of Section 4.15, or as Registrar. Any Paying Agent or Registrar may resign as such upon 30

28

 

days’ prior written notice to the Company and the Trustee; upon resignation of any Paying
Agent or Registrar, the Company shall appoint a successor Paying Agent or Registrar, as the case
may be, complying with the requirements of this Section 2.03, no later than 30 days
thereafter and shall provide notice to the Trustee of such successor Paying Agent or Registrar.

     (c) The Company initially appoints The Bank of New York Mellon Trust Company, N.A. as
Registrar and Paying Agent for the Securities at its Corporate Trust Office. The place of payment
with respect to the Securities, in addition to the Corporate Trust Office of the Trustee, shall be
New York, New York, and at such time, if ever, as the Securities are no longer represented by one
or more Global Securities, the Company shall appoint and maintain a Paying Agent in New York, New
York, the intention of the Company being that, after giving effect to the procedures of the
Depositary respecting payments on Global Securities, the Securities shall at all times be payable
in New York, New York.

     (d) The immunities, protections and exculpations available to the Trustee under this
Supplemental Indenture shall also be available to each Agent, and the Company’s obligations under
Section 7.07 to compensate and indemnify the Trustee shall extend likewise to each Agent.

Section 2.04 [Intentionally Omitted]

Section 2.05 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. If the Trustee is not the Registrar,
the Company shall furnish to the Trustee, in writing at least seven Business Days before each
Interest Payment Date 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.

Section 2.06 Transfer and Exchange

     (a) Transfer and Exchange of Global Securities. A Global Security may not be transferred as a
whole except by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to
the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to
a successor Depositary or a nominee of such successor Depositary. Global Securities also may be
exchanged or replaced, in whole, as provided in Section 2.07 hereof. Owners of beneficial
interests in Global Securities shall not be entitled to receive Definitive Securities unless:

     (1) the Company delivers to the Trustee and the Registrar notice from the Depositary
that it is unwilling or unable to continue to act as Depositary or that it is no longer a
clearing agency registered under the Exchange Act and, in either case, a successor
Depositary is not appointed by the Company within 90 days;

     (2) there has occurred and is continuing an Event of Default and the Depositary
notifies the Trustee and the Registrar of its decision to exchange the Global Securities for
Definitive Securities; or

     (3) any such owner requests (through a Direct or Indirect Participant) an exchange of
its beneficial interest in a Global Security for a Definitive Security, and the Depositary
gives the Trustee and the Registrar, in accordance with the Applicable Procedures, at least
20 days’ prior notice of the request.

29

 

     Upon the occurrence of any of the events in clause (1), (2) or (3) above, Definitive
Securities shall be issued in such names and authorized denominations as the Depositary shall
instruct the Trustee and the Registrar in accordance with the Applicable Procedures. Neither the
Company, the Guarantors nor the Trustee or the Registrar will be liable for any delay by the
Depositary in identifying the owners of beneficial interests in a Global Security, and each of the
Company, the Guarantors, the Trustee and the Registrar may conclusively rely on, and will be
protected in relying on, instructions from the Depository for all purposes of this Supplemental
Indenture.

     (b) Transfer and Exchange of Beneficial Interests in the Global Securities. The transfer and
exchange of beneficial interests in the Global Securities shall be effected through the Depositary,
in accordance with the provisions of this Supplemental Indenture and the Applicable Procedures.
Beneficial interests in any Global Security may be transferred to Persons who take delivery thereof
in the form of a beneficial interest in a Global Security. No written orders or instructions shall
be required to be delivered to the Registrar to effect the transfers described in this Section
2.06(b) and Section 2.06(d) hereof.

     (c) Transfer or Exchange of Beneficial Interests for Definitive Securities. If any holder of
a beneficial interest in a Global Security proposes to exchange such beneficial interest for a
Definitive Security or to transfer such beneficial interest to a Person who takes delivery thereof
in the form of a Definitive Security, then, upon satisfaction of the conditions set forth in
Section 2.06(b) hereof, the Trustee will cause the aggregate principal amount of the applicable
Global Security to be reduced accordingly pursuant to Section 2.06(g) hereof, and the Company will
execute and the Trustee will authenticate and deliver to the Person designated in the instructions
a Definitive Security in the appropriate principal amount. Any Definitive Security issued in
exchange for a beneficial interest pursuant to this Section 2.06(c) will be registered in such name
or names and in such authorized denomination or denominations as the holder of such beneficial
interest requests through instructions to the Registrar from or through the Depositary and the
Participant or Indirect Participant. The Trustee will deliver such Definitive Securities to the
Persons in whose names such Securities are registered.

     (d) Transfer and Exchange of Definitive Securities for Beneficial Interests. A Holder of a
Definitive Security may exchange such Security for a beneficial interest in a Global Security or
transfer such Definitive Security to a Person who takes delivery thereof in the form of a
beneficial interest in a Global Security at any time. Upon receipt of a request for such an
exchange or transfer, the Trustee shall cancel the applicable Definitive Security and the Registrar
shall increase or cause to be increased the aggregate principal amount of one of the Global
Securities.

     (e) Transfer and Exchange of Definitive Securities for Definitive Securities. Upon request by
a Holder of Definitive Securities and such Holder’s compliance with the provisions of this
Section 2.06(e), the Registrar shall register the transfer or exchange of Definitive
Securities. Prior to such registration of transfer or exchange, the requesting Holder shall
present or surrender to the Registrar the Definitive Securities duly endorsed or accompanied by a
written instruction of transfer in form satisfactory to the Registrar duly executed by such Holder
or by its attorney, duly authorized in writing. A Holder of Definitive Securities may transfer
such Securities to a Person who takes delivery thereof in the form of a Definitive Security.

     (f) Legend. The following legend shall appear on the face of each Global Security issued
under this Supplemental Indenture unless specifically stated otherwise in the applicable provisions
of this Supplemental Indenture:

THIS GLOBAL SECURITY IS HELD BY THE DEPOSITARY (AS DEFINED IN THE SUPPLEMENTAL INDENTURE
GOVERNING THIS SECURITY) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF,

SUPPLEMENTAL INDENTURE AND (III) THIS GLOBAL SECURITY MAY BE DELIVERED TO THE TRUSTEE FOR

UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR SECURITIES IN DEFINITIVE FORM, THIS
SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY
OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE
DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY.
UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST
COMPANY (55 WATER STREET, NEW YORK, NEW YORK) (“DTC”) TO THE COMPANY OR ITS AGENT FOR REGISTRATION
OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE &
CO. OR SUCH OTHER NAME AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT
IS MADE TO CEDE & CO. OR SUCH OTHER ENTITY AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF
DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS
WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

     (g) Cancellation and/or Adjustment of Global Securities. At such time as all beneficial
interests in a particular Global Security have been exchanged for Definitive Securities or a
particular Global Security has been redeemed, repurchased or canceled in whole and not in part,
each such Global Security shall be returned to or retained and canceled by the Trustee in
accordance with Section 2.10 hereof. At any time prior to such cancellation, if any
beneficial interest in a Global Security is exchanged for or transferred to a Person who will take
delivery thereof in the form of a beneficial interest in another Global Security or for Definitive
Securities, the principal amount of Securities represented by such Global Security shall be reduced
accordingly and an endorsement shall be made on such Global Security by the Trustee or by the
Securities Custodian at the direction of the Trustee to reflect such reduction; and if the
beneficial interest is being exchanged for or transferred to a Person who will take delivery
thereof in the form of a beneficial interest in another Global Security, such other Global Security
shall be increased accordingly and an endorsement shall be made on such Global Security by the
Trustee or by the Securities Custodian at the direction of the Trustee to reflect such increase.

     (h) General Provisions Relating to Transfers and Exchanges.

     (1) To permit registrations of transfers and exchanges, the Company shall execute and
the Trustee shall authenticate Global Securities and Definitive Securities upon the
Company’s order or at the Registrar’s request.

     (2) No service charge shall be made to a holder of a beneficial interest in a Global
Security or to a Holder of a Definitive Security for any registration of transfer or
exchange, but the Company or the Trustee may require payment of a sum sufficient to cover
any transfer tax or similar governmental charge or other fee required by law and payable in
connection therewith (other than any such transfer taxes or similar governmental charge
payable upon exchange or transfer pursuant to Sections 2.09, 3.06,
3.07, 4.07 and 4.12 hereof).

31

 

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

     (4) None of the Company, the Trustee or the Registrar shall be required (A) to issue,
to register the transfer of or to exchange any Securities during a period of 15 days before
the day of any selection of Securities for redemption under Section 3.02 hereof and
ending at the close of business on the day of selection, (B) to register the transfer of or
to exchange any Securities so selected for redemption in whole or in part, except the
unredeemed portion of any Security being redeemed in part or (C) to register the transfer of
or to exchange a Security between a record date and the next succeeding Interest Payment
Date.

     (5) Prior to the due presentation for registration of transfer of any Security, the
Company, any Guarantor, the Trustee, the Paying Agent or the Registrar may deem and treat
the Person in whose name a Security is registered as the absolute owner of such Security for
the purpose of receiving payment of principal, interest and premium (if any) on such
Security and for all other purposes whatsoever, whether or not such Security is overdue, and
none of the Company, the Trustee, the Paying Agent or the Registrar shall be affected by
notice to the contrary.

     (6) The Trustee shall authenticate Global Securities and Definitive Securities upon
receipt of a written order of the Company signed by one of its Officers and in accordance
with the other provisions of Section 2.02 hereof to the extent applicable.

     (7) All certifications, certificates and Opinions of Counsel required to be submitted
to the Registrar pursuant to this Section 2.06 to effect a registration of transfer
or exchange may be submitted by facsimile.

Section 2.07 Replacement Securities

     (a) If any mutilated Security is surrendered to the Registrar or the Company and the Registrar
and the Company receive evidence to their satisfaction of the destruction, loss or theft of any
Security, the Company will issue and the Trustee, upon receipt of a written order of the Company
(which need not be in the form of an Officers’ Certificate), will authenticate a replacement
Security if the Registrar’s and the Company’s reasonable requirements are met. If required by the
Registrar or the Company, an indemnity bond must be supplied by the Holder that is sufficient in
the judgment of the Registrar, the Trustee and the Company to protect the Company, the Trustee, the
Registrar, any other Agent and any Authenticating Agent from any loss that any of them may suffer
if a Security is replaced.

     (b) Every replacement Security is an additional obligation of the Company and will be entitled
to all of the benefits of this Supplemental Indenture equally and proportionately with all other
Securities duly issued hereunder.

Section 2.08 Outstanding Securities

     (a) 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 in accordance with the provisions hereof, and
those described in

32

 

this Section as not outstanding. Except as set forth in Section 11.06 hereof, a
Security does not cease to be outstanding because the Company or an Affiliate of the Company holds
the Security.

     (b) If a Security is replaced pursuant to Section 2.07 hereof, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held
by a protected purchaser.

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

     (d) If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof)
holds, on a Redemption Date or maturity date, money sufficient to pay Securities payable on that
date, then on and after that date such Securities will be deemed to be no longer outstanding and
will cease to accrue interest.

Section 2.09 Temporary Securities

     Until Definitive Securities 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. Holders of temporary
Securities shall in all respects be entitled to the same benefits under this Supplemental Indenture
as a holder of Definitive Securities.

Section 2.10 Cancellation

     The Company at any time may deliver Securities to the Trustee or any Registrar for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities
surrendered to them for registration of transfer, exchange or payment. The Trustee or the
Registrar and no one else shall cancel and dispose of, in accordance with its policies (but subject
to the record retention requirements of the Exchange Act), all Securities surrendered for
registration of transfer, exchange, payment, replacement or cancellation and shall deliver a
certificate of such disposal to the Company from time to time upon written request. The Company
may not issue new Securities to replace Securities it has redeemed, paid or delivered to the
Trustee or the Registrar for cancellation.

Section 2.11 Defaulted Interest

     If the Company defaults in a payment of interest (“Defaulted Interest”) on the Securities, the
Company shall pay Defaulted Interest (as provided in Section 4.01) in any lawful manner.
The Company may pay the Defaulted Interest to the Persons who are Holders on a subsequent special
record date. The Company shall fix or cause to be fixed (or upon the Company’s failure to do so
the Trustee shall fix pursuant to a written instruction of Holders of at least a majority in
principal amount of the Securities) any such special record date and payment date to the reasonable
satisfaction of the Trustee which special record date shall not be less than 10 days prior to the
payment date for such Defaulted Interest and the Company, or at the Company’s request, the Trustee,
shall promptly mail or cause to be mailed to each Holder a notice that states the special record
date, the payment date and the amount of Defaulted Interest to be paid. The Company shall notify
the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security and
the date of the proposed payment, and at the same time the Company shall deposit with the Trustee
an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted
Interest or shall make arrangements satisfactory to the Trustee for such deposit

33

 

prior to the date of the proposed payment, such money when so deposited to be held in trust
for the benefit of the Persons entitled to such Defaulted Interest as provided in this Section
2.11.

Section 2.12 CUSIP Numbers

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

ARTICLE 3

REDEMPTION

Section 3.01 Notices to Trustee

     (a) If the Company elects to redeem Securities pursuant to Section 3.07 hereof, it
shall notify the Trustee in writing of the Redemption Date and the principal amount of Securities
to be redeemed. The Company shall give each notice to the Trustee provided for in this Section
3.01 at least 15 days before notice of such Redemption Date is given to the Holders unless the
Trustee consents to a shorter period. If such redemption is to be effected pursuant to Section
3.07(b) or 3.07(d), then such notice shall be accompanied by an Officers’ Certificate
to the effect that such redemption will comply with the conditions therein.

     (b) If fewer than all the Securities are to be redeemed, the record date relating to such
redemption shall be selected by the Company and set forth in the related notice given to the
Trustee, which record date shall be not less than 15 days after the date of such notice.

Section 3.02 Selection of Securities to Be Redeemed

     In the case of any partial redemption, selection of the Securities for redemption will be made
by the Trustee in compliance with the requirements of the principal national securities exchange,
if any, on which the Securities are listed or, if the Securities are not listed, then on a pro rata
basis, by such method as the Trustee shall deem to be fair and appropriate and consistent with the
applicable procedures of the Depositary. The Trustee shall make the selection from outstanding
Securities not previously called for redemption. The Trustee may select for redemption portions of
the principal of Securities that have denominations larger than $2,000. Securities and portions of
them the Trustee selects shall be in minimum amounts of $2,000 or a whole multiple of $1,000 in
excess thereof. Provisions of this Supplemental Indenture that apply to Securities called for
redemption also apply to portions of Securities called for redemption. The Trustee shall notify
the Company promptly of the Securities or portions of Securities to be redeemed. The Trustee may
rely upon information provided by the Registrar for purposes of this Section 3.02.

Section 3.03 Notice of Redemption

     (a) At least 30 days but not more than 60 days before a date for redemption of Securities, the
Company shall mail a notice of redemption by first-class mail to each Holder of Securities to be
redeemed at such Holder’s registered address, except that redemption notices may be mailed more
than 60 days

34

 

prior to the Redemption Date if the notice is mailed in connection with a defeasance of the
Securities or a satisfaction and discharge of this Supplemental Indenture in accordance with
Article VIII.

     (b) The notice shall identify the Securities to be redeemed and shall state:

     (1) the Redemption Date;

     (2) the Redemption Price (if then determined and otherwise the basis for its
determination);

     (3) the name and address of the Paying Agent where Securities are to be surrendered;

     (4) that Securities called for redemption must be surrendered to the Paying Agent to
collect the Redemption Price;

     (5) if fewer than all the outstanding Securities are to be redeemed, the identification
and principal amounts of the particular Securities to be redeemed;

     (6) that, unless the Company defaults in making such redemption payment, interest on
Securities (or portion thereof) called for redemption ceases to accrue on and after the
Redemption Date;

     (7) the CUSIP, ISIN or other similar numbers, if any, printed on the Securities being
redeemed;

     (8) that no representation is made as to the correctness or accuracy of the CUSIP, ISIN
or other similar numbers, if any, listed in such notice or printed on the Securities; and

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

     (c) At the Company’s request, the Trustee shall give the notice of redemption in the Company’s
name and at the Company’s expense. In such event, the Company shall provide the Trustee with the
information required by this Section 3.03(b).

Section 3.04 Effect of Notice of Redemption

     (a) Once notice of redemption is mailed to Holders, Securities (or portions thereof) called
for redemption become irrevocably due and payable on the Redemption Date and at the Redemption
Price. Upon surrender to the Paying Agent, such Securities shall be paid at the Redemption Price,
plus accrued and unpaid interest to the Redemption Date; provided that if the Redemption Date is
after the taking of a record of the Holders on a record date and on or prior to the related
Interest Payment Date, the accrued and unpaid interest shall be payable to the Person in whose name
the redeemed Securities are registered on such record date. Failure to give notice or any defect
in the notice to any Holder shall not affect the validity of the notice to any other Holder.

     (b) Any redemption or notice of redemption may, at the Company’s discretion, be subject to one
or more conditions precedent and, in the case of a redemption with the net cash proceeds (other
than Designated Proceeds) of an Equity Offering, notice may be given prior to, and subject to, the
completion of the related Equity Offering.

35

 

Section 3.05 Deposit of Redemption Price

     No later than 10:00 a.m. (New York City time) on the Redemption Date, the Company shall
deposit with the Paying Agent (or, if the Company or a Subsidiary is the Paying Agent, shall
segregate and hold in trust) money sufficient to pay the Redemption Price of and accrued and unpaid
interest on all Securities to be redeemed on that date. If the Company complies with the
provisions of this paragraph, then on and after the Redemption Date, interest will cease to accrue
on the Securities or the portions of Securities called for redemption.

Section 3.06 Securities Redeemed in Part

     Upon cancellation of a Security that is redeemed in part, the Company shall issue and the
Trustee shall authenticate for the Holder (at the Company’s expense) a new Security equal in
principal amount to the unredeemed portion of the Security surrendered. The Trustee shall notify
the Registrar of the issuance of such new Security.

Section 3.07 Optional Redemption

     (a) On or after March 1, 2016, the Company may redeem all or a part of the Securities at any
time and from time to time at its option at the following Redemption Prices (expressed as
percentages of the principal amount) plus accrued and unpaid interest on the Securities, if any, to
the applicable Redemption Date, if redeemed during the 12-month period beginning March 1 of the
years indicated:

	 	 	 	 	 
	Year	 	Redemption Price
	2016
	 	 	103.375	%

	2018
	 	 	101.125	%
	2019 and thereafter
	 	 	100.000	%

     (b) Prior to March 1, 2014, the Company may on one or more occasions redeem up to 35% of the
aggregate principal amount of the outstanding Securities (including Additional Securities) at a
Redemption Price of 106.750% of the principal amount of the Securities, plus accrued and unpaid
interest, if any, thereon to the Redemption Date, with the net cash proceeds (other than Designated
Proceeds) of any one or more Equity Offerings; provided, that (i) at least 65% of the aggregate
principal amount of the Securities (including any Additional Securities) originally issued under
this Supplemental Indenture remains outstanding immediately after each such redemption and (ii)
each such redemption occurs within 180 days of the date of the closing of the related Equity
Offering.

     (c) In addition, at any time and from time to time prior to March 1, 2016, the Company may, at
its option, redeem all or part of the Securities at a Redemption Price equal to:

	 	(1)	 	100% of the principal amount thereof, plus
	 
	 	(2)	 	the Applicable Premium, plus
	 
	 	(3)	 	accrued and unpaid interest, if any, thereon to the Redemption Date.

The Company shall notify the Trustee of the Applicable Premium by delivering to the Trustee, on or
before the applicable Redemption Date, an Officers’ Certificate showing the calculation thereof in
reasonable detail, and the Trustee shall have no responsibility for such calculation.

36

 

     (d) If Holders of not less than 95% in aggregate principal amount of the outstanding
Securities validly tender and do not withdraw such Securities in a Change of Control Offer and the
Company, or any third party making a Change of Control Offer in lieu of the Company as permitted by
Section 4.12, purchases all of the Securities validly tendered and not withdrawn by such
Holders, the Company or such third party will have the right, upon not less than 30 nor more than
60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change
of Control Offer, to redeem all Securities that remain outstanding following such purchase at a
Redemption Price in cash equal to the applicable Change of Control Payment plus, to the extent not
included in the Change of Control Payment, accrued and unpaid interest thereon to the Redemption
Date.

     (e) Any redemption pursuant to this Section 3.07 shall be made pursuant to the
provisions of Sections 3.01 through 3.06 hereof.

     (f) The Securities will not be redeemable at the option of the Company except as set forth in
this Section 3.07. The Company is not, however, prohibited from acquiring the Securities
by means other than a redemption, whether pursuant to a tender offer, open market transactions or
otherwise, so long as the acquisition does not otherwise violate the terms of this Supplemental
Indenture.

ARTICLE 4

COVENANTS

Section 4.01 Payment of Securities

     (a) The Company covenants and agrees for the benefit of the Holders of the Securities that it
shall promptly pay the principal of, premium, if any, and interest on the Securities on the dates
and in the manner provided in the Securities and this Supplemental Indenture. Payments of
principal, premium, if any, and interest on the Securities shall be deemed due for all purposes
under this Supplemental Indenture whether such payments are due at Stated Maturity, upon
redemption, upon required repurchase pursuant to Section 4.07 or 4.12 hereof, upon
declaration or otherwise. Principal, premium, if any, and interest on the Securities shall be
considered paid on the date due if by 11:00 a.m. (New York City time) on such date the Paying Agent
holds in accordance with this Supplemental Indenture money sufficient to pay all principal,
premium, if any, and interest then due.

     (b) The Company will pay, to the extent lawful, interest (including post-petition interest in
any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, at the rate then
in effect on the Securities; it will pay, to the extent lawful, interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without
regard to any applicable grace periods), from time to time on demand at the same rate as on overdue
principal.

Section 4.02 Reports

     (a) Whether or not required by the Commission’s rules and regulations, so long as any
Securities are outstanding, the Company will furnish to the Trustee and each Holder of Securities,
within the time periods specified in the Commission’s rules and regulations:

     (1) all quarterly and annual reports that would be required to be filed with the
Commission on Forms 10-Q and 10-K if the Company were required to file such reports; and

     (2) all current reports that would be required to be filed with the Commission on Form
8-K if the Company were required to file such reports.

37

 

The Company will be deemed to have furnished such reports to the Trustee and the Holders of
Securities if it has filed such reports with the Commission using the EDGAR filing system and such
reports are publicly available and has notified the Trustee, in writing, that such reports are
currently available. All such reports will be prepared in all material respects in accordance with
all of the rules and regulations applicable to such reports. Each annual report on Form 10-K will
include a report on the Company’s consolidated financial statements by the Company’s certified
independent accountants. In addition, the Company will file a copy of each of the reports referred
to in clauses (1) and (2) above with the Commission for public availability within the time periods
specified in the rules and regulations applicable to such reports (unless the Commission will not
accept such a filing) and make such information available to securities analysts and prospective
investors upon request.

     (b) If at any time the Company is no longer subject to the periodic reporting requirements of
the Exchange Act for any reason, the Company will nevertheless continue filing the reports
specified in clauses (1) and (2) of the preceding paragraph of this Section 4.02, with the
Commission within the time periods specified above unless the Commission will not accept such a
filing. The Company agrees that it will not take any action for the purpose of causing the
Commission not to accept any such filings. If, notwithstanding the preceding, the Commission will
not accept the Company’s filings for any reason, the Company will post the reports referred to in
the preceding paragraph of this Section 4.02 on its website within the time periods that
would apply if the Company were required to file those reports with the Commission.

     (c) In addition, the Company and the Guarantors agree that, for so long as any Securities
remain outstanding, if at any time the Company is not required to file with the SEC the reports
required by the preceding paragraphs of this Section 4.02, they will furnish to Holders of
Securities and to prospective investors, upon their request, the information required to be
delivered pursuant to Rule 144A(d)(4) under the Securities Act.

     (d) The Company and the Guarantors shall also comply with Section 314(a) of the TIA.

     (e) Delivery of such reports, information and documents to the Trustee shall be for
informational purposes only and the Trustee’s receipt of such shall not constitute constructive
notice of any information contained therein or determinable from information contained therein,
including our compliance with any of the covenants contained in the Indenture (as to which the
Trustee will be entitled to conclusively rely upon an Officer’s Certificate.)

Section 4.03 Incurrence of Indebtedness and Issuance of Disqualified Stock

     (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly
or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly
liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness
(including Acquired Debt), other than Permitted Debt, and the Company shall not issue, and shall
not permit any of its Restricted Subsidiaries to issue, any Disqualified Stock; provided, however,
that the Company or any Restricted Subsidiary may incur Indebtedness (including Acquired Debt) or
issue shares of Disqualified Stock if the Company’s Fixed Charge Coverage Ratio for the Company’s
most recently ended four full fiscal quarters for which internal financial statements are available
immediately preceding the date on which such additional Indebtedness is incurred or such
Disqualified Stock is issued would have been at least 2 to 1, determined on a pro forma basis
(including a pro forma application of the net proceeds therefrom), as if such additional
Indebtedness had been incurred, or such Disqualified Stock had been issued, as the case may be, at
the beginning of such four-quarter period.

38

 

     (b) The provisions of paragraph (a) of this Section 4.03 shall not apply to the
incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”):

     (1) the incurrence by the Company or any Restricted Subsidiary of Indebtedness pursuant
to one or more Credit Facilities; provided, however, that, immediately after giving effect
to any such incurrence, the aggregate principal amount (or accreted value, as applicable) of
all Indebtedness incurred under this clause (1) and then outstanding does not exceed the
greater of (A) $500 million and (B) 35% of Consolidated Tangible Assets at the time of
incurrence;

     (2) the incurrence by the Company and the Guarantors of Indebtedness represented by the
Initial Securities and the Subsidiary Guarantees issued on the Issue Date;

     (3) the incurrence by the Company or any of its Restricted Subsidiaries of Existing
Indebtedness;

     (4) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted
Refinancing Indebtedness, the net proceeds of which are applied to refinance any
Indebtedness incurred in respect of any Indebtedness described under clauses (2), (3), (4),
(8) or (11) of this paragraph or incurred pursuant to the first paragraph of this
Section 4.03;

     (5) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany
Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided,
however, that (A) if the Company or any Guarantor is the obligor and a Restricted Subsidiary
of the Company that is not a Guarantor is the obligee on such Indebtedness, such
Indebtedness will be subordinated to the payment in full of all Obligations with respect to
the Securities and the Subsidiary Guarantees, as the case may be, and (B) (i) any subsequent
issuance or transfer of Equity Interests that results in any such Indebtedness being held by
a Person other than the Company or a Restricted Subsidiary of the Company and (ii) any sale
or other transfer of any such Indebtedness to a Person that is not either the Company or a
Restricted Subsidiary of the Company shall be deemed, in each case, to constitute an
incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case
may be, that is not then permitted by this clause (5);

     (6) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness
represented by Capital Lease Obligations, mortgage financings or purchase money obligations
(including any Acquired Debt), in each case, incurred in connection with the purchase of, or
for the purpose of financing the purchase of, the cost of construction, improvement or
development of, property, plant or equipment used in the Permitted Business of the Company
or a Restricted Subsidiary of the Company or incurred to extend, refinance, renew, replace,
defease or refund any such purchase price or cost of construction, improvement or
development, in an aggregate principal amount not to exceed $50 million at any time
outstanding;

     (7) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness
consisting of Hedging Obligations entered into in the ordinary course of business and not
for speculative purposes;

     (8) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness
arising from agreements of the Company or any of its Restricted Subsidiaries providing for
indemnification, adjustment of purchase price or similar obligations, in each case, incurred
in connection with the disposition or acquisition of any business, assets or a Restricted
Subsidiary of the Company or any business or assets of its Restricted Subsidiaries, other
than

39

 

guarantees of Indebtedness incurred by any Person acquiring all or any portion of such
business, assets or a Restricted Subsidiary of the Company or any of its Restricted
Subsidiaries for the purposes of financing such acquisition; provided, however, that (A)
such Indebtedness is not reflected on the balance sheet of the Company or any of its
Restricted Subsidiaries (contingent obligations referred to in a footnote to financial
statements and not otherwise reflected on the balance sheet will not be deemed to be
reflected on such balance sheet for purposes of this clause (A)) and (B) the maximum
liability in respect of all such Indebtedness incurred in connection with a disposition
shall at no time exceed the gross proceeds including noncash proceeds (the Fair Market Value
of such noncash proceeds being measured at the time received and without giving effect to
any subsequent changes in value) actually received by the Company and its Restricted
Subsidiaries in connection with such disposition;

     (9) the guarantee by the Company or any Restricted Subsidiary of Indebtedness of the
Company or a Restricted Subsidiary of the Company that was permitted to be incurred by any
other provision of this Section 4.03; provided that the guarantee of any
Indebtedness of a Restricted Subsidiary of the Company that ceases to be such a Restricted
Subsidiary shall be deemed a Restricted Investment at the time such Restricted Subsidiary’s
status terminates in an amount equal to the maximum principal amount so guaranteed, for so
long as, and to the extent that, such guarantee remains outstanding;

     (10) the issuance by a Restricted Subsidiary of the Company of Disqualified Stock to
the Company or to any of its Restricted Subsidiaries; provided, however, that any subsequent
event or issuance or transfer of any Equity Interests that results in the owner of such
Disqualified Stock ceasing to be the Company or any of its Restricted Subsidiaries or any
subsequent transfer of such preferred stock to a Person, other than the Company or one of
its Restricted Subsidiaries, shall be deemed to be an issuance of Disqualified Stock by such
Subsidiary that was not permitted by this clause (10);

     (11) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted
Acquisition Indebtedness;

     (12) the incurrence by the Company or any of its Restricted Subsidiaries of
Indebtedness incurred in the ordinary course of business under (A) documentary letters of
credit, or surety bonds or insurance contracts, which are to be repaid in full not more than
one year after the date on which such Indebtedness is originally incurred to finance the
purchase of goods by the Company or a Restricted Subsidiary of the Company, (B) standby
letters of credit, surety bonds or insurance contracts issued for the purpose of supporting
(i) workers’ compensation or similar liabilities of the Company or any of its Restricted
Subsidiaries or (ii) performance, payment, deposit or surety obligations of the Company or
any of its Restricted Subsidiaries and (C) bid, advance payment and performance bonds and
surety bonds or similar insurance contracts for the Company and its Restricted Subsidiaries,
and refinancings thereof; and

     (13) the incurrence by the Company or any of its Restricted Subsidiaries of
Indebtedness (in addition to Indebtedness permitted by any other provision of this covenant)
in an aggregate principal amount (or accreted value, as applicable) not to exceed the
greater of (A) $50 million at any one time outstanding and (B) 3.5% of Consolidated Tangible
Assets as of any date of incurrence after giving pro forma effect to such incurrence and the
application of proceeds therefrom.

     (c) To the extent the Company’s Unrestricted Subsidiaries incur Non-Recourse Indebtedness and
any such Indebtedness ceases to be Non-Recourse Indebtedness of such Unrestricted Subsidiary, then

40

 

such event shall be deemed to constitute an incurrence of Indebtedness by a Restricted
Subsidiary of the Company that was subject to this covenant.

     (d) Neither the Company nor any Guarantor will incur any Indebtedness (including Permitted
Debt) that is contractually subordinated in right of payment to any other Indebtedness of the
Company or such Guarantor, as the case may be, unless such Indebtedness is also contractually
subordinated in right of payment to the Securities or the Subsidiary Guarantees, as the case may
be, on substantially identical terms; provided, however, that no Indebtedness of any Person will be
deemed to be contractually subordinated in right of payment to any other Indebtedness of such
Person solely by virtue of being unsecured.

     (e) For purposes of determining compliance with this Section 4.03, in the event that
an item of proposed Indebtedness (including Acquired Debt) meets the criteria of more than one of
the categories of Permitted Debt set forth in Section 4.03(b) or is entitled to be incurred
pursuant to Section 4.03(a), the Company will, in its sole discretion, classify (or later
classify or reclassify) in whole or in part such item of Indebtedness in any manner that complies
with this Section 4.03 and such item of Indebtedness or a portion thereof may be classified
(or later classified or reclassified) in whole or in part as having been incurred under more than
one of the applicable clauses of Section 4.03(b) or pursuant to Section 4.03(a).
Accrual of interest, the accretion of accreted value and the payment of interest in the form of
additional Indebtedness will not be deemed to be an incurrence of Indebtedness for purposes of this
Section 4.03.

     (f) For purposes of determining compliance with any U.S. dollar-denominated restriction on the
incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated
in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on
the date such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in
the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to
refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause
the applicable U.S. dollar-dominated restriction to be exceeded if calculated at the relevant
currency exchange rate in effect on the date of such refinancing, such U.S. dollar-dominated
restriction shall be deemed not to have been exceeded so long as the principal amount of such
refinancing Indebtedness does not exceed the principal amount of such Indebtedness being
refinanced. Notwithstanding any other provision of this covenant, the maximum amount of
Indebtedness that the Company may incur pursuant to this covenant shall not be deemed to be
exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal
amount of any Permitted Refinancing Indebtedness, if incurred in a different currency from the
Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable
to the currencies in which such Permitted Refinancing Indebtedness is denominated that is in effect
on the date of such refinancing.

Section 4.04 Restricted Payments

     (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly
or indirectly:

     (1) declare or pay any dividend or make any other payment or distribution on account of
the Company’s or any of its Restricted Subsidiaries’ Equity Interests (including, without
limitation, any payment in connection with any merger or consolidation involving the Company
or any of its Restricted Subsidiaries) or to the direct or indirect holders of the Company’s
or any of its Restricted Subsidiaries’ Equity Interests in their capacity as such, in each
case other than dividends or distributions declared or paid in Equity Interests (other than
Disqualified Stock) of the Company or declared or paid to the Company or any of its
Restricted Subsidiaries;

41

 

     (2) purchase, redeem or otherwise acquire or retire for value (including without
limitation, in connection with any merger or consolidation involving the Company) any Equity
Interests of the Company (other than any such Equity Interests owned by a Restricted
Subsidiary of the Company);

     (3) make any payment on or with respect to, or purchase, redeem, defease or otherwise
acquire or retire for value, any Subordinated Obligation, except a payment of interest or
principal at its Stated Maturity; or

     (4) make any Investment other than a Permitted Investment (all such payments and other
actions set forth in clauses (1) through (3) above and this clause (4) being collectively
referred to as “Restricted Payments”), unless at the time of and after giving effect to such
Restricted Payment:

     (A) no Default or Event of Default shall have occurred and be continuing; and

     (B) the Company would, at the time of such Restricted Payment and after giving
pro forma effect thereto as if such Restricted Payment had been made at the
beginning of the applicable four-quarter period, have been permitted to incur at
least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio
test set forth in Section 4.03(a); and

     (C) such Restricted Payment, together with the aggregate amount of all other
Restricted Payments made by the Company or any of its Restricted Subsidiaries after
the Issue Date (excluding Restricted Payments permitted by clause (2), (3), (4),
(5), (6), (8), (9), (10), (11) or (12) of Section 4.04(b)), is less than the

allocated portions thereof, would be permitted under the various provisions of one or more of
clauses (1) through (12) of Section 4.04(b) and Section 4.04(a). The amount of all

on the Issue Date or acquired after that date, securing any Indebtedness, unless:

Restricted Subsidiary, the Securities or Subsidiary Guarantees, as applicable, are
contemporaneously secured by a Lien on such property or assets on a senior basis to the

Guarantees, as applicable, have to such Subordinated Obligations until such time as such
Subordinated Obligations are no longer so secured by a Lien; and

     (2) in the case of Liens securing Senior Indebtedness of the Company or a Restricted
Subsidiary, the Securities or Subsidiary Guarantees, as applicable, are contemporaneously
secured by a Lien on such property or assets on an equal and ratable basis with the Senior
Indebtedness so secured until such time as such Senior Indebtedness is no longer so secured
by a Lien.

     (b) Upon the occurrence of an Investment Grade Rating Event but not before then, the covenant
set forth in Section 4.05(c) shall become effective and shall apply to the Company and its
Subsidiaries.

     (c) If the Company or any Subsidiary incurs any Indebtedness secured by a Lien (other than
Permitted Liens of the types described in clause (2), (5), (6), (7), (8), (9), (10), (11), (13),
(14), (15), (16) or (17) of the definition of the term “Permitted Liens” in Section 1.01)
on any asset, whether now owned or hereafter acquired, or if any Subsidiary that is not a Guarantor
of the Securities incurs any Indebtedness of any kind, the Company or such Subsidiary, as the case
may be, will secure the Securities equally and ratably with (or, at its option, prior to) the
Indebtedness so secured until such time as such Indebtedness is no longer secured by a Lien, or
will guarantee the Securities on a full and unconditional senior basis (if a Subsidiary incurs
unsecured Indebtedness), in each case unless the aggregate amount of all Indebtedness secured by a
Lien and the Attributable Amounts of all Sale/Leaseback Transactions would not exceed 12.5% of
Consolidated Net Tangible Assets.

Section 4.06 Dividend and Other Payment Restrictions Affecting Subsidiaries

     (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly

     (1) (x) pay dividends or make any other distributions to the Company or any of its
Restricted Subsidiaries on its Capital Stock or (y) pay any Indebtedness owed to the Company
or

45

 

any of its Restricted Subsidiaries; provided, that the priority of any preferred stock
in receiving dividends or liquidating distributions prior to the payment of dividends or
liquidating distributions on common stock shall not be deemed to be a restriction on the
ability to make distributions on Capital Stock;

     (2) make loans or advances to the Company or any of its Restricted Subsidiaries; or

     (3) transfer any of its properties or assets to the Company or any of its Restricted

taken as a whole, are no more restrictive with respect to such dividend, distribution or
other payment restrictions and loan or investment restrictions than those contained in the
Credit Facilities as in effect on the Issue Date;

     (2) (i) this Supplemental Indenture, the Securities or the Subsidiary Guarantees, (ii)
the Existing Indenture, the Existing Notes or the Existing Guarantees or (iii) any other

restrictive with respect to such dividend, distribution or other payment restrictions and

violation of, any other provisions of this Supplemental Indenture;

     (4) applicable law or any applicable rule, regulation or order;

relating to any property or assets, of a Person acquired by the Company or any of its
Restricted Subsidiaries as in effect at the time of such acquisition, which encumbrance or
restriction is not applicable to any Person, or the properties or assets of any Person,
other than the Person, or the property or assets of the Person or such Person’s
subsidiaries, so acquired, provided, that, in the case of Indebtedness, such Indebtedness
was permitted by the terms of this Supplemental Indenture to be incurred;

     (6) restrictions of the nature described in clause (3) of Section 4.06(a) by
reason of customary non-assignment provisions in contracts, agreements, licenses and leases
entered into in the ordinary course of business;

     (7) purchase money obligations for property acquired in the ordinary course of business

limit the right of the debtor to dispose of assets securing such Indebtedness;

     (10) Permitted Refinancing Indebtedness in respect of Indebtedness referred to in
clauses (1), (2), (5), (7) and (9) of this Section 4.06(b), provided that the
restrictions contained in the agreements governing such Permitted Refinancing Indebtedness
are no more restrictive with respect to such dividend, distribution or other payment
restrictions and loan or investment restrictions than those contained in the agreements
governing the Indebtedness being refinanced;

     (11) provisions with respect to the disposition or distribution of assets in joint
venture agreements, asset sale agreements, agreements relating to Sale/Leaseback
Transactions, stock sale agreements and other similar agreements entered into in the

Section 4.07 Asset Sales

     (a) The Company will not, and will not permit any of its Restricted Subsidiaries to,
consummate an Asset Sale unless:

     (1) The Company or the Restricted Subsidiary, as the case may be, receives
consideration at the time of the Asset Sale at least equal to the Fair Market Value (which
shall give effect to the assumption by another Person of any liabilities as provided for in
clause (2)(A) of this paragraph and which, in the case of an Asset Sale involving
consideration not exceeding $100 million, need not be determined by the Board of Directors)
of the assets or Equity Interests issued or sold or otherwise disposed of; and

     (2) (x) at least 75% of the consideration received in such Asset Sale is in the form of
cash or Cash Equivalents or (y) the Fair Market Value of all forms of consideration other
than cash or Cash Equivalents received for all Asset Sales since the Issue Date does not
exceed in the aggregate 10% of Consolidated Net Worth of the Company at the time each
determination is made; provided that any of the following items shall be deemed to be cash
and Cash Equivalents for the purposes of this clause (2):

     (A) the assumption of any liabilities (as shown on the Company’s or the
Restricted Subsidiary’s most recent balance sheet) of the Company or any Restricted
Subsidiary of the Company (other than liabilities that are by their terms
subordinated to Securities issued under this Supplemental Indenture or any
Subsidiary Guarantee) by the transferee of any such assets pursuant to a customary
novation agreement that releases the Company or the Restricted Subsidiary from
further liability;

47

 

     (B) any securities, notes or other obligations received by the Company or any
such Restricted Subsidiary from such transferee that are converted by the Company or
the Restricted Subsidiary into cash or Cash Equivalents within 180 days following
their receipt (to the extent of cash or Cash Equivalents received);

     (C) other assets or rights used or useful in a Permitted Business, including,
without limitation, assets or Investments of the nature or type described in clause
(13) of the definition of “Permitted Investments” in Section 1.01; and

     (D) accounts receivable of a business retained by the Company or any of its
Restricted Subsidiaries following the sale of such business; provided, that such
accounts receivable are not (i) past due more than 60 days and (ii) do not have a
payment date greater than 90 days from the date of the invoice creating such
accounts receivable;

provided, that any Asset Sale pursuant to a condemnation, appropriation or other similar taking,
including by deed in lieu of condemnation, or pursuant to the foreclosure or other enforcement of a
Lien incurred not in violation of Section 4.05 or exercise by the related lienholder of
rights with respect thereto, including by deed or assignment in lieu of foreclosure, shall not be
required to satisfy the conditions set forth in clauses (1) and (2) of this paragraph.

     (b) Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company or
the Restricted Subsidiary, as the case may be, may apply such Net Proceeds, at its option:

     (1) to prepay, repay, purchase, repurchase or redeem any Senior Indebtedness of the
Company or any Restricted Subsidiary of the Company;

     (2) to acquire a controlling interest in another business or all or substantially all
of the assets or operating line of another business, in each case engaged in a Permitted
Business;

     (3) to make capital expenditures; or

     (4) to acquire other non-current assets to be used in a Permitted Business, including,
without limitation, assets or Investments of the nature or type described in clause (13) of
the definition of “Permitted Investments” in Section 1.01;

provided that the Company or the applicable Restricted Subsidiary will be deemed to have complied
with clause (2) or (3) of this sentence if, within 365 days of such Asset Sale, the Company or such
Restricted Subsidiary shall have commenced and not completed or abandoned an expenditure or
Investment, or entered into a binding agreement with respect to an expenditure or Investment, in
compliance with clause (2) or (3), and that expenditure or Investment is substantially completed
within a date one year and six months after the date of such Asset Sale. Pending the final
application of any such Net Proceeds, the Company may temporarily reduce Indebtedness under any
Credit Facility or otherwise expend or invest such Net Proceeds in any manner that is not
prohibited by this Supplemental Indenture. Any Net Proceeds from Asset Sales described in this
paragraph that are not applied or invested as provided in the first sentence of this paragraph
shall be deemed to constitute “Excess Asset Sale Proceeds.”

     (c) When the aggregate amount of Excess Asset Sale Proceeds exceeds $30 million, the Company
shall make an offer to the Holders of Securities and the holders of any other Senior Indebtedness
that is subject to requirements with respect to the application of net proceeds from asset sales
that are substantially similar to those contained in this Section 4.07 (an “Asset Sale
Offer”) to purchase on a pro rata basis (with the Excess Asset Sale Proceeds prorated between the
Holders of the

48

 

Securities and such holders of such other Senior Indebtedness based upon outstanding aggregate
principal amounts) the maximum principal amount of the Securities and such other Senior
Indebtedness that may be purchased or prepaid, as applicable, out of the prorated Excess Asset Sale
Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount thereof (or
accreted amount in the case of any Senior Indebtedness issued with original issue discount) plus
accrued and unpaid interest thereon to the date of purchase (the “Asset Sale Payment”), in
accordance with the procedures set forth in this Section 4.07. To the extent that the
aggregate principal amount of Securities and other Senior Indebtedness tendered (and electing to be
redeemed or repaid, as applicable) pursuant to an Asset Sale Offer is less than the Excess Asset
Sale Proceeds, the Company and its Restricted Subsidiaries may use any remaining Excess Asset Sale
Proceeds for general corporate purposes and any other purpose not prohibited by this Supplemental
Indenture. If the aggregate principal amount of the Securities and such other Senior Indebtedness
surrendered by holders thereof exceeds the amount of the prorated Excess Asset Sale Proceeds, the
Company shall select the Securities and such other Senior Indebtedness to be purchased on a pro
rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Asset Sale Proceeds
shall be reset at zero.

     (d) When the Company becomes obligated to make an Asset Sale Offer, the Company will mail a
notice to each Holder describing the transaction or transactions that constitute the Asset Sale and
offering to repurchase Securities on the date (the “Asset Sale Payment Date”) specified in such
notice, which date will be no earlier than 30 days nor later than 60 days from the date such notice
is mailed, pursuant to the procedures required by this Supplemental Indenture and described in such
notice.

     (e) On the Asset Sale Payment Date, the Company will, to the extent lawful:

     (1) accept for payment all Securities or portions thereof properly tendered pursuant to
the Asset Sale Offer, subject to proration based on the amount of Excess Asset Sale Proceeds
pursuant to clause (c) above of this Section 4.07;

     (2) deposit with the Paying Agent an amount equal to the amount of Excess Asset Sale
Proceeds that, after giving effect to proration with holders of other Senior Indebtedness
pursuant to clause (c) above of this Section 4.07, is allocable to the Securities or
portions thereof so tendered (or, if less, the aggregate Asset Sale Payment for all
Securities validly tendered and not withdrawn); and

     (3) deliver or cause to be delivered to the Trustee the Securities so accepted together
with an Officers’ Certificate stating the aggregate principal amount of Securities or
portions thereof being purchased by the Company.

     (f) The Paying Agent will promptly mail (or cause to be transferred through the facilities of
the Depositary) to each Holder of Securities so tendered and not withdrawn and accepted for payment
in accordance with this Section 4.07, the Asset Sale Payment for such tendered Securities,
and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to
each Holder a new Security equal in principal amount to any unpurchased portion of the Securities
surrendered, if any, by such Holder; provided that each such new Security will be in a minimum
principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

     (g) If the Asset Sale Payment Date is on or after an interest payment record date and on or
before the related Interest Payment Date, any accrued and unpaid interest will be paid to the
Person in whose name a purchased Security is registered on such record date, and no other interest
will be payable to Holders who tender Securities pursuant to the Asset Sale Offer.

49

 

     (h) The Company will publicly announce the results of the Asset Sale Offer on or as soon as
practicable after the date such Asset Sale Offer is completed.

     (i) The Company will comply with the requirements of Rule 14e-l under the Exchange Act and any
other securities laws and regulations thereunder to the extent such laws and regulations are
applicable in connection with an Asset Sale Offer. To the extent that the provisions of any
securities laws or regulations conflict with the provisions of this Section 4.07, the
Company will comply with the applicable securities laws and regulations and will not be deemed to
have breached its obligations under this Section 4.07 by virtue of the Company’s compliance
with such securities laws or regulations.

Section 4.08 Transactions with Affiliates

     (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly
or indirectly, make any payment to, or sell, lease, transfer or otherwise dispose of any properties
or assets to, or purchase any property or assets from, or enter into or make or amend any
transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate of any such Person (each of the foregoing, an “Affiliate Transaction”) if
such Affiliate Transaction involves aggregate consideration in excess of $1 million, unless:

     (1) such Affiliate Transaction is on terms that are no less favorable to the Company or
the relevant Restricted Subsidiary than those that could have been obtained in a transaction
by the Company or such Restricted Subsidiary with an unrelated Person or, if no comparable
transaction is available with which to compare such Affiliate Transaction, such Affiliate
Transaction is otherwise fair to the Company or the relevant Restricted Subsidiary from a
financial point of view, evidenced (if required by clause (2) of this Section
4.08(a)) by the Officers’ Certificate provided for in clause (2) of this Section
4.08(a); and

     (2) the Company delivers to the Trustee:

     (A) with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of at least $20 million but
equal to or less than $40 million, an Officers’ Certificate certifying that such
Affiliate Transaction complies with clause (1) above; and

     (B) with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $40 million, a
resolution of its Board of Directors set forth in an Officers’ Certificate
certifying that such Affiliate Transaction complies with clause (1) of this
Section 4.08(a) and that such Affiliate Transaction has been approved by a
majority of the disinterested members of its Board of Directors;

     (b) None of the following shall be deemed to be Affiliate Transactions and therefore shall not
be subject to the provisions of Section 4.08(a):

     (1) any employment, equity award, equity option or equity appreciation agreement or
plan, agreement or other similar compensation plan or arrangement entered into by the
Company or any of its Restricted Subsidiaries in the ordinary course of its business;

     (2) transactions between or among (A) the Company and one or more Restricted
Subsidiaries and (B) any Restricted Subsidiaries;

50

 

     (3) the performance of any written agreement in effect on the Issue Date, as such
agreement may be amended, modified or supplemented from time to time; provided, however,
that any amendment, modification or supplement entered into after the Issue Date will be
permitted only to the extent that its terms do not adversely affect the rights of any
Holders of the Securities (as determined in good faith by an Officer of the Company, and, if
such amendment, modification or supplement involves aggregate consideration in excess of $40
million, as determined in good faith by the Board of Directors) as compared to the terms of
the agreement in effect on the Issue Date;

     (4) loans or advances to officers, directors and employees for moving, entertainment
and travel expenses, drawing accounts and similar expenditures and other purposes, in each
case, in the ordinary course of business;

     (5) maintenance in the ordinary course of business of customary benefit programs or
arrangements for employees, officers or directors, including vacation plans, health and life
insurance plans, deferred compensation plans and retirement or savings plans and similar
plans;

     (6) fees and compensation paid to, and indemnity provided on behalf of, officers,
directors, employees or consultants of the Company or any of its Restricted Subsidiaries in
their capacity as such, to the extent such fees and compensation are reasonable and
customary;

     (7) sales of Equity Interests of the Company (other than Disqualified Stock) to
Affiliates of the Company or any of its Restricted Subsidiaries;

     (8) Restricted Payments that are permitted by Section 4.04; and

     (9) any transactions between the Company or any Restricted Subsidiary and any Person, a
director of which is also a director of the Company or a Restricted Subsidiary; provided
that such director abstains from voting as a director of the Company or the Restricted
Subsidiary, as applicable, in connection with the approval of the transaction.

Section 4.09 Designation of Restricted and Unrestricted Subsidiaries

     (a) The Board of Directors may designate any Unrestricted Subsidiary to be a Restricted
Subsidiary only if:

     (1) immediately after giving effect to such designation, the Company could incur at
least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test
under Section 4.03(a) or the Fixed Charge Coverage Ratio of the Company immediately
after giving effect to such designation would not be less than the Fixed Charge Coverage
Ratio of the Company immediately prior to such designation;

     (2) immediately before and immediately after giving effect to such designation, no
Default or Event of Default shall have occurred and be continuing; and

determination as to whether such designation would be made in compliance with this Section, all
outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid
in cash) in the Subsidiary so designated will be deemed to be Restricted Payments at the time of
such designation and will reduce the amount available for Restricted Payments under Section
4.04(a). All such outstanding Investments will be deemed to constitute Investments in an
amount equal to the greater of (1) the net book value (determined in accordance with GAAP) of such
Investments at the time of such designation and (2) the Fair Market Value of such Investments at
the time of such designation.

Section 4.10 Additional Subsidiary Guarantees

     If, after the Issue Date, any Restricted Subsidiary (other than a Foreign Subsidiary) of the
Company that is not already a Guarantor (whether or not acquired or created by the Company or
another Restricted Subsidiary after the Issue Date) incurs any Indebtedness, or guarantees any
other Indebtedness of the Company or a Guarantor, in either case in excess of a De Minimis Amount,
then the Company shall cause such Restricted Subsidiary to become a Guarantor by executing a
supplemental indenture substantially in the form of Exhibit C hereto and delivering it to
the Trustee within 180 days of the date on which it incurred or guaranteed such Indebtedness, as
the case may be.

Section 4.11 [Intentionally Omitted.]

Section 4.12 Change of Control

     (a) If a Change of Control occurs, each Holder of Securities will have the right to require
the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in
excess thereof) of that Holder’s Securities pursuant to the offer described below (the “Change of
Control Offer”) at an offer price in cash equal to 101% of the aggregate principal amount thereof
plus accrued and unpaid interest thereon to the date of purchase (the “Change of Control Payment”).
Within 30 days following any Change of Control, the Company will mail to each Holder of Securities
a notice describing the transaction or transactions that constitute the Change of Control and
offering to repurchase the Securities on the date specified in such notice, which date shall be no
earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of
Control Payment Date”), pursuant to the procedures required by this Section 4.12 and
described in such notice.

     (b) On the Change of Control Payment Date, the Company will, to the extent lawful:

     (1) accept for payment all Securities or portions thereof properly tendered pursuant to
the Change of Control Offer;

     (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in
respect of all Securities or portions thereof so tendered; and

     (3) deliver or cause to be delivered to the Trustee the Securities so accepted together
with an Officers’ Certificate stating the aggregate principal amount of Securities or
portions thereof being purchased by the Company.

     (c) The Paying Agent will promptly mail (or cause to be transferred through the facilities of
the Depositary) to each Holder of Securities so tendered and not withdrawn the Change of Control
Payment for such tendered Securities, and the Trustee will promptly authenticate and mail (or cause
to be

52

 

transferred by book entry) to each Holder a new Security equal in principal amount to any
unpurchased portion of the Securities surrendered, if any, by such Holder; provided that each such
new Security will be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in
excess thereof. The Trustee will notify the Registrar of the issuance of the new Security.

     (d) If the Change of Control Payment Date is on or after an interest payment record date and
on or before the related interest payment date, any accrued and unpaid interest will be paid to the
Person in whose name a Security is registered at the close of business on such record date, and no
other interest will be payable to Holders who tender pursuant to the Change of Control Offer.

     (e) The Company will publicly announce the results of the Change of Control Offer on or as
soon as practicable after the Change of Control Payment Date.

     (f) The provisions described above in this Section that require the Company to make a Change
of Control Offer following a Change of Control will be applicable regardless of whether or not any
other provisions of this Supplemental Indenture are applicable.

     (g) The Company will not be required to make a Change of Control Offer upon a Change of
Control if a third party makes the Change of Control Offer in the manner, at the times and
otherwise in compliance with the requirements set forth in this Section applicable to a Change of
Control Offer made by the Company and purchases all Securities validly tendered and not withdrawn
under such Change of Control Offer. A Change of Control Offer may be made with respect to the
Securities in advance of a Change of Control, and conditional upon the occurrence of such Change of
Control, if a definitive agreement for the Change of Control is in place at the time of making the
Change of Control Offer.

     (h) The Company will comply with the requirements of Rule 14e-l under the Exchange Act and any
other securities laws and regulations thereunder to the extent such laws and regulations are
applicable in connection with the repurchase of the Securities as a result of a Change of Control.
To the extent that the provisions of any securities laws or regulations conflict with the
provisions of this Section 4.12, the Company will comply with the applicable securities
laws and regulations and will not be deemed to have breached its obligations under this Section
4.12 by virtue of the Company’s compliance with such securities laws or regulations.

Section 4.13 Maintenance of Office or Agency for Registration of Transfer, Exchange and Payment of
Securities

     So long as any of the Securities shall remain outstanding, the Company will, in accordance
with Section 2.03 hereof, maintain an office or agency (which may be an office of the
Trustee or an affiliate of the Trustee, or the Registrar) in the continental United States where
the Securities may be surrendered for exchange or registration of transfer as provided in this
Supplemental Indenture, where notices and demands to or upon the Company in respect to the
Securities may be served, and where the Securities may be presented or surrendered for payment.
The Company may also from time to time designate one or more other offices or agencies in the
continental United States where Securities may be presented or surrendered for any and 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 under
Section 2.03 to maintain an office or agency in New York, New York where any Definitive
Securities may be presented or surrendered for payment. The Company will give to Trustee prompt
written notice of the location of any such office or agency and of any change of location thereof.
In case the Company shall fail to maintain any such office or agency or shall fail to give such
notice of the location or of any change in the location thereof, such surrenders, presentations and
demands may be made and notices may be served at the designated Corporate Trust Office of the
Trustee, and the

53

 

Company hereby appoints the Trustee its agent to receive at the aforesaid office all such
surrenders, presentations, notices and demands.

Section 4.14 [Intentionally Omitted.]

Section 4.15 Provision as to Paying Agent

     (a) If the Company shall appoint a Paying Agent other than the Trustee, in accordance with the
terms of this Supplemental Indenture, it will cause such Paying Agent to execute and deliver to the
Trustee an instrument in which such Agent shall undertake, subject to the provisions of this
Section 4.15:

     (1) that it will hold all sums held by it as such agent for the payment of the
principal of, premium, if any, or interest on the Securities (whether such sums have been
paid to it by the Company or by any other obligor on the Securities) in trust for the
benefit of the Holders of the Securities and will notify the Trustee of the receipt of sums
to be so held;

     (2) that it will give the Trustee notice of any failure by the Company (or by any other
obligor on the Securities) to make any payment of the principal of, premium, if any, or
interest on the Securities when the same shall be due and payable;

     (3) that it will at any time during the continuance of any Event of Default specified
in Section 6.01, upon the written request of the Trustee, deliver to the Trustee all
sums so held in trust by it; and

     (4) that it will acknowledge, accept and agree to comply in all aspects with the
provisions of this Supplemental Indenture relating to the duties, rights and liabilities of
such Paying Agent.

     (b) If the Company shall not act as its own Paying Agent, it will, by 10:00 a.m. (New York
City time) on the due date of the principal of or premium, if any, or interest on any Securities,
deposit with such Paying Agent a sum in same day funds sufficient to pay the principal of, premium,
if any, or interest so becoming due, such sum to be held in trust for the benefit of the Holders of
Securities entitled to such principal of or premium, if any, or interest, and (unless such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of its failure so to act.

     (c) If the Company shall act as its own Paying Agent, it will, by 11:00 a.m. (New York City
time) on each due date of the principal of or premium, if any, or interest on the Securities, set
aside, segregate and hold in trust for the benefit of the Persons entitled thereto, a sum
sufficient to pay such principal or premium or interest so becoming due and will notify the Trustee
of any failure to take such action.

     (d) Anything in this Section 4.15 to the contrary notwithstanding, the Company may, at
any time, for the purpose of obtaining a satisfaction and discharge of this Supplemental Indenture,
or for any other reason, pay or cause to be paid to the Paying Agent for delivery to the Trustee
all sums held in trust by it, as required by this Section 4.15, such sums to be delivered
by the Paying Agent to the Trustee to be held by the Trustee upon the trusts herein contained.

     (e) Anything in this Section 4.15 to the contrary notwithstanding, the agreement to
hold sums in trust as provided in this Section 4.15 is subject to the provisions of
Section 8.04 and Section 8.06.

54

 

Section 4.16 Maintenance of Corporate Existence

     So long as any of the Securities shall remain outstanding, the Company will at all times
(except as otherwise provided or permitted in Article V of this Supplemental Indenture) do
or cause to be done all things necessary to preserve and keep in full force and effect its
corporate existence.

Section 4.17 Compliance Certificate

     (a) The Company and the Guarantors shall deliver to the Trustee within 90 days after the end
of each fiscal year of the Company ending after the Issue Date a statement (which need not be an

or the principal financial officer of each of the Company and the Guarantors, stating that a review
of the activities of the Company and its Restricted Subsidiaries during the preceding fiscal year
has been made under the supervision of the signing Officers with a view to determining whether each
of the Company and the Guarantors has performed its obligations under this Supplemental Indenture,
and further stating whether or not the signers know of any Default or Event of Default that
occurred during such period. If they do, the certificate shall describe such Default or Event of
Default, its status and what action the Company is taking or proposes to take with respect thereto.

     (b) So long as any of the Securities are outstanding, the Company will deliver to the Trustee,
forthwith upon any Officer becoming aware of any Default or Event of Default, an Officers’
Certificate specifying such Default or Event of Default and what action the Company is taking or
proposes to take with respect thereto.

Section 4.18 Taxes

     The Company will pay, and will cause each of its Significant Subsidiaries to pay, prior to
delinquency, all material taxes, assessments, and governmental levies except such as are contested
in good faith and by appropriate proceedings or where the failure to effect such payment would not
have a material adverse effect on the Company and its Restricted Subsidiaries, taken as a whole.

Section 4.19 Stay, Extension and Usury Laws

     The Company covenants (to the extent that it may lawfully do so) that it will not at any time
insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any
stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may
affect the covenants or the performance of this Supplemental Indenture; and the Company (to the
extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not, by resort to any such law, 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 has been enacted.

Section 4.20 Termination of Certain Covenants

Sections 4.03, 4.04, 4.05(a) and 4.06 through 4.12 and in
Section 5.01 (except for clause (1) of Section 5.01(a)) and clause (6) of
Section 6.01 will cease to apply to the Company and its Subsidiaries, as the case may be,
and will no longer have effect. Instead, the covenant set forth in Section 4.05(c) will
thereupon apply to the Company and its Subsidiaries.

55

     (a) The Company may not: (1) consolidate or merge with or into another Person; or (2) sell,

supplemental indenture;

     (2) immediately before and after such transaction no Default or Event of Default has

     (3) except in the case of a consolidation or merger of the Company with or into a
Restricted Subsidiary, or a sale, assignment, transfer, conveyance or other disposition of
properties or assets to the Company or a Restricted Subsidiary, either:

     (A) immediately after giving pro forma effect to such transaction as if such

would have a Fixed Charge Coverage Ratio that is not less than the Fixed Charge
Coverage Ratio of the Company immediately prior to such transaction;

     (B) immediately after giving pro forma effect to such transaction as if such

ARTICLE 6

DEFAULTS AND REMEDIES

Section 6.01 Events of Default

     (a) Each of the following is an “Event of Default”:

     (1) default for 30 days in the payment when due of interest on the Securities;

     (2) default in the payment when due of the principal of, or premium, if any, on the
Securities;

     (3) failure by the Company or any of its Restricted Subsidiaries to comply with
Section 4.12 or 5.01 hereof for 30 days after receipt of written notice
specified in Section 6.01(b) below;

     (4) failure by the Company or any of its Restricted Subsidiaries for 60 days after
receipt of written notice specified in Section 6.01(b) below to comply with any of
its other agreements contained in this Supplemental Indenture or the Securities (other than
a failure that is subject to clause (1), (2) or (3) of this Section 6.01(a));

     (5) default under any mortgage, indenture or instrument under which there may be issued
or by which there may be secured or evidenced any Indebtedness for money borrowed by the
Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the
Company or any of its Restricted Subsidiaries), whether such Indebtedness or guarantee now
exists, or is created after the Issue Date, if that default:

     (A) is caused by a failure to pay principal of, or premium, if any, or interest
on such Indebtedness prior to the expiration of the grace period provided in such
Indebtedness (a “Payment Default”); or

57

 

     (B) results in the acceleration of such Indebtedness prior to its express
maturity;

and, in each case, the principal amount of any such Indebtedness, together with the principal
amount of any other such Indebtedness under which there has been a Payment Default or the maturity
of which has been so accelerated, aggregates without duplication $30 million or more;

     (6) failure by the Company or any of its Restricted Subsidiaries to pay final judgments
aggregating in excess of $30 million (excluding amounts covered by insurance), which
judgments are not paid, discharged or stayed for a period of 60 days;

     (7) except as permitted by this Supplemental Indenture, any Subsidiary Guarantee of a
Guarantor shall be held in any judicial proceeding to be unenforceable or invalid or shall
cease for any reason to be in full force and effect or any Guarantor, or any Person acting
on behalf of any Guarantor, shall deny or disaffirm its obligations under its Subsidiary
Guarantee; and

     (8) (A) the Company or a Significant Subsidiary or a group of Subsidiaries that, taken
together, would constitute a Significant Subsidiary pursuant to or within the meaning of any
Bankruptcy Law:

     (i) commences a voluntary case or proceeding;

     (ii) consents to the entry of an order for relief against it in an
involuntary case or proceeding in which it is a debtor;

     (iii) consents to the appointment of a Custodian of it or for any
substantial part of its property;

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

     (v) consents to the institution of a bankruptcy or an insolvency
proceeding against it;

or takes any comparable action under any foreign laws relating to insolvency;
or

     (B) a court of competent jurisdiction enters an order or decree under any
Bankruptcy Law that:

     (i) is for relief against the Company or any Significant Subsidiary or
a group of Subsidiaries that, taken together, would constitute a Significant
Subsidiary in an involuntary case in which it is a debtor;

     (ii) appoints a Custodian of the Company or any Significant Subsidiary
or a group of Subsidiaries that, taken together, would constitute a
Significant Subsidiary or for any substantial part of its property; or

     (iii) orders the winding up or liquidation of the Company or any
Significant Subsidiary or a group of Subsidiaries that, taken together would
constitute a Significant Subsidiary;

58

 

     or any similar relief is granted under any foreign laws and the order, decree
or relief remains unstayed and in effect for 60 consecutive days.

     (b) However, a Default under clauses (3) and (4) of Section 6.01(a) will not
constitute an Event of Default until the Trustee or the Holders of at least 25% in principal amount
of the outstanding Securities notify the Company of the Default and the Company does not cure such
Default within the time specified in clauses (3) and (4) of Section 6.01(a) after receipt
of such notice. Such notice must specify the Default, demand that it be remedied and state that
such notice is a “Notice of Default.”

     (c) Whether or not a group of Subsidiaries would constitute, when taken together, a
Significant Subsidiary will be determined, for purposes of Section 6.01(a), on the basis of
the latest available consolidated financial statements of the Company and its Subsidiaries.

Section 6.02 Acceleration of Maturity; Rescission and Annulment

     (a) If an Event of Default (other than an Event of Default described in clause (8) of
Section 6.01(a)) occurs and is continuing, the Trustee by notice to the Company, or the
Holders of at least 25% in principal amount of the outstanding Securities by notice to the Company
and the Trustee, may declare the principal of, premium, if any, and accrued and unpaid interest, if
any, on all the Securities to be due and payable. Upon such a declaration, such principal, premium
and accrued and unpaid interest will be due and payable immediately. If an Event of Default
described in clause (8) of Section 6.01(a) occurs and is continuing, the principal of,
premium, if any, and accrued and unpaid interest on all the Securities will become and be
immediately due and payable without any further action or notice on the part of the Trustee or any
Holders. The Holders of a majority in outstanding principal amount of the Securities by notice to
the Trustee may on behalf of the Holders of all the Securities rescind any such acceleration with
respect to the Securities and its consequences if (1) rescission would not conflict with any
judgment or decree of a court of competent jurisdiction, (2) all existing Events of Default, other
than the nonpayment of the principal of, premium, if any, and interest on the Securities that have
become due solely by such declaration of acceleration, have been cured or waived and (3) there has
been paid or deposited with the Trustee a sum sufficient to pay all amounts due to the Trustee, its
agents and its counsel incurred in connection with such Default or Event of Default.

     (b) In the case of an Event of Default specified in clause (5) of Section 6.01(a),
such Event of Default and all consequences thereof (excluding, however, any resulting payment
default) will be annulled, waived and rescinded with respect to the Securities, automatically and
without any action by the Trustee or the Holders of the Securities, if within 60 days after such
Event of Default first arose the Company delivers an Officers’ Certificate to the Trustee stating
that (1) the Indebtedness or guarantee that is the basis for such Event of Default has been paid or
discharged, (2) the holders of the Indebtedness have rescinded or waived the acceleration giving
rise to such Event of Default or (3) the default that is the basis for such Event of Default has
been otherwise cured; provided, however, that in no event shall an acceleration of the principal
amount of the Securities pursuant to Section 6.02(a) be annulled, waived or rescinded upon
the happening of any such events.

Section 6.03 Other Remedies

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

     (b) 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

59

 

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. No remedy is exclusive
of any other remedy. All available remedies are cumulative to the extent permitted by law.

Section 6.04 Waiver of Past Defaults

     Subject to the last sentence of Section 6.02(a), the Holders of a majority in outstanding
principal amount of the Securities, by notice to the Trustee may on behalf of the Holders of all
the Securities waive an existing Default or Event of Default and its consequences hereunder except
a Default or Event of Default in the payment of the principal of, premium, if any, or interest on a
Security. When a Default or Event of Default is waived, it is deemed cured, but no such waiver
shall extend to any subsequent or other Default or Event of Default or impair any consequent right.

Section 6.05 Control by Majority

     The Holders of a majority in outstanding principal amount of the Securities have the right to
direct the time, method and place of conducting any proceeding for exercising any remedy available
to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee
may refuse to follow any direction that conflicts with law or this Supplemental Indenture or,
subject to Section 7.01 hereof, that the Trustee determines is unduly prejudicial to the
rights of other Holders or would 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. Subject to Section 7.01, prior to taking any action hereunder, the Trustee
shall be entitled to indemnification reasonably satisfactory to it against all loss, liability and
expense caused by taking or not taking such action.

Section 6.06 Limitation on Suits

     (a) Except to enforce the right to receive payment of principal, premium (if any) or interest
when due, a Holder may not pursue any remedy with respect to this Supplemental Indenture, the
Securities or the Subsidiary Guarantees unless:

     (1) the Holder has previously given the Trustee written notice stating that an Event of
Default is continuing;

     (2) Holders of at least 25% in outstanding principal amount of the Securities have made
a written request to the Trustee to pursue the remedy;

     (3) such Holder or Holders have furnished the Trustee reasonable security or indemnity
against any loss, liability or expense;

     (4) the Trustee has not complied with the Holders’ request within 60 days after receipt
of the request and the furnishing of security or indemnity; and

     (5) the Holders of a majority in outstanding principal amount of the Securities have
not given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with
the request during such 60-day period.

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

60

 

Section 6.07 Rights of Holders to Receive Payment

     Notwithstanding any other provision of this Supplemental Indenture, the right of any Holder to
receive payment of principal of, premium, if any, and interest on the Securities held by such
Holder, on or after the respective due dates expressed in the Securities, or to bring suit for the
enforcement of any such payment on or after such respective dates, shall not be impaired or
affected without the consent of such Holder.

Section 6.08 Collection Suit by Trustee

     If an Event of Default specified in Section 6.01(a)(1) or Section 6.01(a)(2)
hereof occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of
an express trust against the Company or any Guarantor for the whole amount then due and owing
(together with interest on any unpaid interest to the extent lawful) and the amounts provided for
in Section 7.07 hereof to cover the costs and expenses of collection, including the
reasonable compensation, disbursement and advances of the Trustee, its agents and counsel.

Section 6.09 Trustee May File Proofs of Claim

     The Trustee may file such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Holders allowed in any judicial
proceedings relative to the Company or any Guarantor or their respective creditors or properties
and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any
election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian
in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due it for the compensation, expenses, disbursements and
advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under
Section 7.07 hereof.

Section 6.10 Priorities

     (a) If the Trustee collects any money or property pursuant to this Article VI, it
shall pay out the money or property in the following order:

     First: costs and expenses of collection, including all sums paid or advanced by the
Trustee hereunder and the compensation, expenses and disbursements of the Trustee, its
agents, and counsel and all other amounts due to the Trustee under Section 7.07
hereof;

     Second: to Holders for amounts due and unpaid on the Securities for principal and
interest and premium, if any, ratably, without preference or priority of any kind, according
to the amounts due and payable on the Securities for principal and interest and premium, if
any, respectively; and

     Third: to the Company.

     (b) The Trustee may fix a record date and payment date for any payment to Holders pursuant to
this Section 6.10. At least 15 days before such record date, the Trustee shall mail to
each Holder and the Company a notice that states the record date, the payment date and amount to be
paid.

61

 

Section 6.11 Undertaking for Costs

     In any suit for the enforcement of any right or remedy under this Supplemental Indenture or in
any suit against the Trustee for any action taken or omitted by it as 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 hereof
or a suit by Holders of more than 10% in outstanding principal amount of the Securities.

ARTICLE 7

TRUSTEE

Section 7.01 Duties of Trustee

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

     (b) Except during the continuance of an Event of Default: (i) the Trustee undertakes to
perform such duties and only such duties as are specifically set forth in this Supplemental
Indenture and no implied covenants or obligations shall be read into this Supplemental Indenture
against the Trustee; and (ii) 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
Supplemental Indenture. However, the Trustee shall examine the certificates and opinions to
determine whether or not they conform to the requirements of this Supplemental Indenture.

     (c) The Trustee may not be relieved from liability 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) hereof;

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

take in good faith in accordance with a direction received by it pursuant to Section
6.05 hereof.

its own funds or otherwise incur financial liability in the performance of any of its duties
hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to
believe that repayment of such funds or security or indemnity satisfactory to it against such risk
or liability is not reasonably assured to it.

Section 7.02 Rights of Trustee.

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

     (j) anything in this Indenture notwithstanding, in no event shall the Trustee be liable for
any special, indirect, punitive, incidental or consequential loss or damage of any kind whatsoever
(including but not limited to loss of profit), even if the Company has been advised as to the

Section 7.03 Individual Rights of Trustee

     The Trustee in its individual or any other capacity may become the owner or pledgee of
Securities and may otherwise deal with the Company or its Affiliates with the same rights it would
have if it were not Trustee. However, in the event that the Trustee acquires any conflicting
interest (as defined in the TIA) after a Default has occurred and is continuing, it must eliminate
such conflict within 90 days, apply to the SEC for permission to continue as Trustee or resign.
The Trustee is also subject to Sections 7.10 and 7.11 hereof.

Section 7.04 Trustee’s Disclaimer

     The Trustee shall not be responsible for and makes no representation as to the validity or

Company’s use of the proceeds from the Securities, it shall not be responsible for the use or
application of any money received by any Paying Agent (other than itself as Paying Agent), and it
shall not be responsible for any statement of the Company in this Supplemental Indenture or in any
document issued in connection with the sale of the Securities or in the Securities other than the
Trustee’s certificate of authentication.

Section 7.05 Notice of Defaults

     If a Default or Event of Default occurs and is continuing and if a Trust Officer has actual
knowledge thereof, the Trustee shall mail to each Holder 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 relating to
payment of principal of, premium, if any, or interest on, any Security (including payments pursuant
to the redemption or required repurchase provisions of such Security), the Trustee may withhold the
notice if and so long as its board of directors, the Executive Committee of its board of directors
or a committee of its Trust Officers in good faith determines that withholding the notice is in the
interests of Holders.

64

 

Section 7.06 Reports by Trustee to Holders

     (a) Within 60 days after each May 15 beginning with the May 15 of the year following the date
of this Supplemental Indenture, the Trustee shall mail to each Holder a brief report that complies
with Trust Indenture Act Section 313(a) (but if no event described in Trust Indenture Act §313(a)
has occurred within the 12 months preceding the reporting date, no report need be transmitted).
The Trustee also shall comply with Trust Indenture Act Section 313(b). The Trustee shall also
transmit by mail all reports required by Trust Indenture Act Section 313(c).

     (b) A copy of each report at the time of its mailing to Holders shall be mailed to the Company
and filed with the SEC and each stock exchange (if any) on which the Securities are listed. The
Company agrees to notify promptly the Trustee whenever the Securities become listed on any stock
exchange and of any delisting thereof.

Section 7.07 Compensation and Indemnity

     (a) The Company shall pay to the Trustee from time to time, and the Trustee shall be entitled
to, reasonable compensation for its services, which may be set forth in a separate fee agreement
between the Trustee and the Company. The Trustee’s compensation shall not be limited by any law on
compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon
request for all reasonable out-of-pocket expenses incurred or made by it, including costs of
collection, costs of preparing and reviewing reports, certificates and other documents, costs of
preparation and mailing of notices to Holders and reasonable costs of counsel retained by the
Trustee in connection with the delivery of an Opinion of Counsel or otherwise, in addition to the
compensation for its services. Such expenses shall include the reasonable compensation and
expenses, disbursements and advances of the Trustee’s agents and counsel. The Company shall
indemnify and hold harmless the Trustee (in its individual and trustee capacities) and its
officers, directors and agents against any and all loss, liability, claims, action, suit, cost or
expense (including reasonable attorneys’ fees) of any kind and nature whatsoever incurred by it in
connection with the administration of this trust and the performance of its duties hereunder,
including the costs and expenses of enforcing this Supplemental Indenture (including this
Section 7.07) and of defending itself against any claims (whether asserted by any Holder,
the Company or otherwise). The Trustee shall notify the Company promptly of any claim for which it
may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company
of its obligations hereunder. The Company shall defend the claim and the Trustee may have separate
counsel and the Company shall pay the fees and expenses of such counsel. The Company is not
required to reimburse any expense or indemnify against any loss, liability, claim, suit, cost or
expense incurred by the Trustee through the Trustee’s own willful misconduct or negligence.

     (b) To secure the Company’s payment obligations 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
other than money or property held in trust to pay principal of, premium (if any) and interest on
particular Securities.

     (c) The Company’s payment obligations pursuant to this Section 7.07 shall survive the
discharge of this Supplemental Indenture and the resignation or removal of the Trustee. When the
Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(a)(8)
hereof with respect to the Company, the expenses are intended to constitute expenses of
administration under any Bankruptcy Law.

65

 

Section 7.08 Replacement of Trustee

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

     (b) The Trustee may resign at any time by so notifying the Company. The Holders of a majority
in outstanding principal amount of the Securities may remove the Trustee by so notifying the
Trustee and the Company and may appoint a successor Trustee. The Company may remove the Trustee
if: (i) the Trustee fails to comply with Section 7.10 hereof; (ii) the Trustee is adjudged
bankrupt or insolvent; (iii) a Custodian or other public officer takes charge of the Trustee or its
property; or (iv) the Trustee otherwise becomes incapable of acting.

outstanding principal amount of the Securities and such Holders do not reasonably promptly appoint
a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in
such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a
successor Trustee.

     (d) A successor Trustee shall deliver a written acceptance of its appointment to the retiring
Trustee and to the Company. 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
Trustee under this Supplemental Indenture. The successor Trustee shall mail a notice of its
succession to the 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 hereof.

     (e) If a successor Trustee does not take office within 60 days after the retiring Trustee
resigns or is removed, the retiring Trustee or the Holders of 10% in outstanding principal amount
of the Securities may, at the expense of the Company, petition any court of competent jurisdiction
for the appointment of a successor Trustee.

     (f) If the Trustee fails to comply with Section 7.10 hereof after written notice
thereto, the Holders of at least 10% in principal amount of the then outstanding Securities may
petition any court of competent jurisdiction for the removal of the Trustee and the appointment of
a successor Trustee.

     (g) Notwithstanding the replacement of the Trustee pursuant to this Section 7.08, the
Company’s obligations under Section 7.07 hereof shall continue for the benefit of the
retiring Trustee.

Section 7.09 Successor Trustee by Merger

     (a) If the Trustee consolidates with, merges or converts into, or transfers all or
substantially all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation or banking association without any
further act shall be the successor Trustee.

     (b) If at the time such successor or successors by merger, conversion or consolidation to the
Trustee shall succeed to the trusts created by this Supplemental Indenture, any of the Securities
shall have been authenticated but not delivered, any such successor to the Trustee may adopt the
certificate of authentication of any predecessor Trustee, and deliver such Securities so
authenticated; and if 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

66

 

Trustee; and in all such cases such certificates shall have the full force which it is
anywhere in the Securities or in this Supplemental Indenture provided that the certificate of the
Trustee shall have.

Section 7.10 Eligibility; Disqualification

     The Trustee shall at all times satisfy the requirements of Trust Indenture Act Section 310(a).
There shall at all times be a Trustee hereunder that is a corporation organized and doing business
under the laws of the United States of America or of any state thereof that is authorized under
such laws to exercise corporate trustee power, that is subject to supervision or examination by
federal or state authorities and that has a combined capital and surplus of at least $50 million as
set forth in its most recent published annual report of condition. The Trustee shall comply with
Trust Indenture Act Section 310(b).

Section 7.11 Preferential Collection of Claims Against Company

     The Trustee shall comply with Trust Indenture Act Section 311(a), excluding any creditor
relationship listed in Trust Indenture Act Section 311(b). A Trustee who has resigned or been
removed shall be subject to Trust Indenture Act Section 311(a) to the extent indicated.

Company irrevocably deposits or causes to be deposited with the Trustee as trust funds in trust
solely for the benefit of the Holders money in U.S. dollars, non-callable Government Securities, or
a combination thereof, in such amounts as will be sufficient without consideration of any

interest to the date of Stated Maturity or redemption, (3) no Default has occurred and is
continuing on the date of such deposit or shall occur as a result of such deposit (other than a

which the Company is a party or by which the Company is bound, (4) the Company has paid or caused
to be paid all sums then payable by it under this Supplemental Indenture and (5) the Company has
delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment

67

 

(“legal defeasance option”), and after giving effect to such legal defeasance, any omission to

obligations under Section 4.02, Section 4.03, Section 4.04, Section
4.05, Section 4.06, Section 4.07, Section 4.08, Section 4.09,

liability in respect of any term, condition or limitation set forth in any such Section, whether
directly or indirectly, by reason of any reference elsewhere herein to any such Section or by
reason of any reference in any such Section to any other provision herein or in any other document
and such omission to comply with such Sections shall no longer constitute a Default or an Event of

6.01(a)(5) or Section 6.01(a)(6) hereof or (with respect only to Significant
Subsidiaries) Section 6.01(a)(8) hereof, and the events specified in such Sections shall no
longer constitute an Event of Default (this clause (2) being referred to as the “covenant

if:

     (a) the Company shall have irrevocably deposited with the Trustee, in trust, for the benefit
of the Holders of the Securities, cash in U.S. dollars, non-callable Government Securities, or a
combination thereof, in such amounts as will be sufficient, in the opinion of a nationally
recognized firm of independent public accountants, to pay the principal of, premium, if any, and
interest on the outstanding Securities on the Stated Maturity or on the applicable Redemption Date,
as the case may be, and the Company must specify whether the Securities are being defeased to
Stated Maturity or to a particular Redemption Date;

Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming
that (1) the Company has received from, or there has been published by, the Internal Revenue
Service a ruling or (2) since the Issue Date, there has been a change in the applicable federal
income tax law, in either case

68

 

to the effect that, and based thereon such Opinion of Counsel shall
confirm that, the Holders of the
outstanding Securities will not recognize income, gain or loss for federal income tax purposes
as a result of such legal defeasance and will be subject to federal income tax on the same amounts,

not occurred;

     (c) in the case of the covenant defeasance option, the Company shall have delivered to the
Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming
that the Holders of the outstanding Securities will not recognize income, gain or loss for federal
income tax purposes as a result of such covenant defeasance and will be subject to federal income
tax on the same amounts, in the same manner and at the same times as would have been the case if
such covenant defeasance option had not occurred;

     (d) no Default shall have occurred and be continuing on the date of such deposit (other than a
Default resulting from the incurrence of Indebtedness or the grant of Liens securing such
Indebtedness, all or a portion of the proceeds of which will be applied to such deposit) or insofar
as Events of Default from bankruptcy or insolvency events are concerned, at any time in the period
ending on the 91st day after the date of deposit;

     (e) such deposit will not result in a breach or violation of, or constitute a default under,
any material agreement or instrument (other than this Supplemental Indenture) to which the Company
or any of its Restricted Subsidiaries is a party or by which the Company or any of its Restricted
Subsidiaries is bound, or if such breach, violation or default would occur, which is not waived as
of, and for all purposes, on and after, the date of such deposit;

     (f) the Company shall have delivered to the Trustee an Officers’ Certificate stating that the

held by the Company or any Subsidiary shall be discharged from any trust hereunder), and,
thereafter, Holders entitled to the money must look to the Company for payment as unsecured general

69

 

creditors; provided, however, that, if any Definitive Securities are then outstanding, the Trustee
or such
Paying Agent, before being required to make any such repayment, may at the expense of the
Company cause to be published once, in The New York Times and The Wall Street Journal (national
edition), notice that such money remains unclaimed and that, after a date specified therein, which
will not be less than 30 days from the date of such notification or publication, any unclaimed
balance of such money then remaining will be repaid to the Company.

Section 8.05 Indemnity for Government Securities

     The Company shall pay and shall indemnify the Trustee against any tax, fee or other charge
imposed on or assessed against deposited Government Securities or the principal and interest
received on such Government Securities.

Section 8.06 Reinstatement

     If the Trustee or any Paying Agent is unable to apply any money or Government Securities in
accordance with this Article VIII 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 under this Supplemental Indenture and
the Securities shall be revived and reinstated as though no deposit had occurred pursuant to this
Article VIII until such time as the Trustee or such Paying Agent is permitted to apply all
such money or Government Securities in accordance with this Article VIII; provided,
however, that, if the Company has made any payment in respect of any Securities because of the
reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of
such Securities to receive such payment from the money or Government Securities held by the Trustee
or any Paying Agent.

     (b) The consent of the Holders is not necessary under this Section 9.02 to approve the
particular form of any proposed amendment or waiver. It is sufficient if the consent approves the
substance of the proposed amendment or waiver.

     (c) After an amendment, supplement or waiver under this Section 9.02 becomes
effective, the Company shall mail to each Holder of Securities affected thereby a notice briefly
describing such amendment. The failure to give such notice to any or all Holders, or any defect
therein, shall not impair or affect the validity of any amendment, supplement or waiver under this
Section 9.02.

Section 9.03 Compliance with Trust Indenture Act

     Every amendment to this Supplemental Indenture, the Securities or the Subsidiary Guarantees
shall comply with the Trust Indenture Act as then in effect.

Section 9.04 Revocation and Effect of Consents and Waivers

     (a) A consent to an amendment, supplement or waiver by a Holder of a Security shall bind the
Holder and every subsequent Holder of that Security or portion of the Security that evidences the
same debt as the consenting Holder’s Security (or any Holder of a Security issued upon the
registration of transfer or exchange thereof or in lieu thereof), even if notation of the
amendment, supplement or waiver is not made on the Security. However, any such Holder or
subsequent Holder may revoke the consent as to such Holder’s Security or portion of the Security if
the Trustee receives the written notice of revocation before the date the amendment, supplement or
waiver becomes effective. After an amendment, supplement or waiver becomes effective in accordance
with its terms, it shall bind every Holder.

     (b) The Company may, but shall not be obligated to, fix a record date for the purpose of
determining the Holders entitled to give their consent or take any other action described above or
required or permitted to be taken pursuant to this Supplemental Indenture. If a record date is
fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Holders at
the close of business on such record date (or their duly designated proxies), and only those
Persons, shall be entitled to give such consent or to revoke any consent previously given or to
take any such action, whether or not such Persons continue to be Holders after such record date,
and for this purpose the Securities then outstanding shall be computed as of such record date. No
such consent shall become valid or effective more than 120 days after such record date.

Section 9.05 Notation on or Exchange of Securities

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

72

 

Section 9.06 Trustee to Sign Amendments

     The Trustee shall sign any amendment or supplement authorized pursuant to this Article
IX 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 such
amendment or supplement the Trustee shall be entitled to receive, and (subject to Section
7.01 hereof) shall be fully protected in relying upon, in addition to the documents required by
Section 11.04, an Officers’ Certificate and an Opinion of Counsel each stating that the execution
of such amendment or supplement is authorized or permitted by this Supplemental Indenture.

ARTICLE 10

SUBSIDIARY GUARANTEES

Section 10.01 Subsidiary Guarantees

     (a) Each Guarantor hereby, jointly and severally, guarantees to each Holder and to the Trustee
and its successors and assigns the full and punctual payment of principal of, premium (if any) and
interest on the Securities when due, whether at Stated Maturity, or upon redemption, required
repurchase pursuant to Section 4.07 or Section 4.12 hereof, acceleration or
otherwise, and all other monetary obligations owing by the Company under this Supplemental
Indenture (including obligations owing to the Trustee) and the Securities (all the foregoing being
hereinafter collectively called the “Guaranteed Obligations”). The Guarantors further agree that
the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or
further assent from the Guarantors, and that the Guarantors will remain bound under this
Article X notwithstanding any extension or renewal of any Guaranteed Obligation.

     (b) The Guarantors waive presentation to, demand of payment from and protest to the Company of
any of the Guaranteed Obligations and also waive notice of protest for nonpayment. The Guarantors
waive notice of any Default under the Securities or the Guaranteed Obligations. The obligations of
the Guarantors hereunder shall not be affected by: (1) the failure of any Holder or the Trustee to
assert any claim or demand or to enforce any right or remedy against the Company or any other
Person under this Supplemental Indenture, the Securities or any other agreement or otherwise; (2)
any extension or renewal of any Guaranteed Obligation; (3) any rescission, waiver, amendment,
modification or supplement of any of the terms or provisions of this Supplemental Indenture (other
than this Article X), the Securities or any other agreement; (4) the release of security,
if any, held by any Holder or the Trustee for the Guaranteed Obligations or any of them; (5) the
failure of any Holder or the Trustee to exercise any right or remedy against any other guarantor of
the Guaranteed Obligations; (6) any change in the ownership of the Company; or (vii) any other act
or thing or omission or delay to do any other act or thing which may or might in any manner or to
any extent vary the risk of the Guarantors or would otherwise operate as a discharge of the
Guarantors as a matter of law or equity, except for payment of the Securities in full.

     (c) The Guarantors, jointly and severally, further agree that their Subsidiary Guarantees
herein constitute a guarantee of payment when due (and not a guarantee of collection) and waive any
right to require that any resort be had by any Holder or the Trustee to security, if any, held for
payment of the Guaranteed Obligations.

     (d) The obligations of the Guarantors hereunder shall not be subject to any reduction,
limitation, impairment or termination for any reason (except to the extent provided in Section
10.02 hereof), including any claim of waiver, release, surrender, alteration or compromise, and
shall not be

73

 

subject to any defense, setoff, counterclaim, recoupment or termination whatsoever or by
reason of the invalidity, illegality or unenforceability of the Obligations or otherwise.

     (e) The Guarantors, jointly and severally, further agree that their Subsidiary Guarantees
herein shall continue to be effective or be reinstated, as the case may be, if at any time payment,
or any part thereof, of any Guaranteed Obligation is rescinded or must otherwise be restored by any
Holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise.

     (f) In furtherance of the foregoing and not in limitation of any other right which any Holder
or the Trustee has at law or in equity against the Guarantors by virtue hereof, upon the failure of
the Company to pay any Guaranteed Obligation when and as the same shall become due, whether at
Stated Maturity, upon redemption, required repurchase, acceleration or otherwise, the Guarantors
hereby promise to and will, upon receipt of written demand by the Trustee, forthwith pay, or cause
to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of (i) the unpaid
principal amount of such Guaranteed Obligations and (ii) accrued and unpaid interest on such
Guaranteed Obligation (but only to the extent not prohibited by law).

     (g) The Guarantors, jointly and severally, agree that, as between the Guarantors, on the one
hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the Guaranteed
Obligations may be accelerated as provided in Article VI for the purposes of the Subsidiary
Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the Guaranteed Obligations, and (y) in the event of any declaration of
acceleration of such Guaranteed Obligations as provided in Article VI, such Guaranteed
Obligations (whether or not due and payable) shall forthwith become due and payable by the
Guarantors for the purposes of this Section 10.01.

     (h) The Guarantors, jointly and severally, also agree to pay any and all costs and expenses
(including reasonable attorneys’ fees) incurred by the Trustee or any Holder in enforcing any
rights under this Section 10.01.

Section 10.02 Limitation on Liability

     Each Guarantor, and by its acceptance of Securities, each Holder, hereby confirm that it is
the intention of all such parties that the Subsidiary Guarantee of such Guarantor not constitute a
fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance
Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent
applicable to any Subsidiary Guarantee. To effectuate the foregoing intention, the Trustee, the
Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor will be
limited to the maximum amount that will, after giving effect to such maximum amount and all other
contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after
giving effect to any collections from, rights to receive contribution from or payments made by or
on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this
Article X, result in the obligations of such Guarantor under its Subsidiary Guarantee not
constituting a fraudulent transfer or conveyance.

Section 10.03 Execution and Delivery of Subsidiary Guarantee

     (a) To evidence its Subsidiary Guarantee set forth in Section 10.01, each Guarantor
hereby agrees that a notation of such Subsidiary Guarantee substantially in the form attached as
Exhibit D hereto will be endorsed by manual or facsimile signature by an Officer of such
Guarantor on each Security authenticated and delivered by the Trustee and that this Supplemental
Indenture (or a supplemental indenture substantially in form of Exhibit C hereof) will be
executed on behalf of such Guarantor by one of its Officers.

74

 

     (b) Each Guarantor hereby agrees that its Subsidiary Guarantee set forth in Section
10.01 will remain in full force and effect notwithstanding any failure to endorse on each
Security a notation of such Subsidiary Guarantee. If an Officer whose facsimile signature is on
the Subsidiary Guarantee no longer holds that office at the time the Trustee authenticates the
Security on which the Subsidiary Guarantee is endorsed, the Subsidiary Guarantee will be valid
nevertheless.

     (c) The delivery of any Security by the Trustee, after the authentication thereof hereunder,
will constitute due delivery of the Subsidiary Guarantee set forth in this Supplemental Indenture
on behalf of the Guarantors.

Section 10.04 Successors and Assigns

     Except as otherwise provided in Section 10.09 hereof, this Article X shall be
binding upon the Guarantors and their successors and assigns and shall inure to the benefit of the
successors and assigns of the Trustee and the Holders and, in the event of any transfer or
assignment of rights in accordance with the terms of this Supplemental Indenture by any Holder or
the Trustee, the rights and privileges conferred upon that party in this Supplemental Indenture and
in the Securities shall automatically extend to and be vested in such transferee or assignee, all
subject to the terms and conditions of this Supplemental Indenture, the Securities and the
Subsidiary Guarantees.

Section 10.05 No Waiver

     Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising
any right, power or privilege under this Article X shall operate as a waiver thereof, nor
shall a single or partial exercise thereof preclude any other or further exercise of any right,
power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein
expressly specified are cumulative and not exclusive of any other rights, remedies or benefits
which either may have under this Article X at law, in equity, by statute or otherwise.

Section 10.06 Right of Contribution

     Each Guarantor hereby agrees that to the extent that a Guarantor shall have paid more than its
proportionate share of any payment made hereunder, such Guarantor shall be entitled to seek and
receive contribution from and against any other Guarantor hereunder who has not paid its
proportionate share of such payment. Each Guarantor’s right of contribution shall be subject to
the terms and conditions of this Article X. The provisions of this Section 10.06
shall in no respect limit the obligations and liabilities of any Guarantor to the Trustee and the
Holders and each Guarantor shall remain liable to the Trustee and the Holders for the full amount
guaranteed by such Guarantor hereunder.

Section 10.07 No Subrogation

     Notwithstanding any payment or payments made by any of the Guarantors hereunder, no Guarantor
shall be entitled to exercise any rights of subrogation it may have to any of the rights of the
Trustee or any Holder against the Company or any other Guarantor or any collateral security or
guarantee or right of offset held by the Trustee or any Holder for the payment of the Guaranteed
Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement
from the Company or any other Guarantor in respect of payments made by such Guarantor hereunder,
until all amounts owing to the Trustee and the Holders by the Company on account of the Guaranteed
Obligations are paid in full. If any amount shall be paid to any Guarantor on account of such
subrogation rights at any time when all of the Obligations shall not have been paid in full, such
amount shall be held by such Guarantor in trust for the Trustee and the Holders, segregated from
other funds of such Guarantor, and shall, forthwith upon

75

 

receipt by such Guarantor, be turned over to the Trustee in the exact form received by such
Guarantor (duly indorsed by such Guarantor to the Trustee, if required), to be applied against the
Guaranteed Obligations.

Section 10.08 Modification

     No modification, amendment or waiver of any provision of this Article X, nor the
consent to any departure by the Guarantors therefrom, shall in any event be effective unless the
same shall be made in accordance with Article IX hereof. No notice to or demand on the
Guarantors in any case shall entitle the Guarantors to any other or further notice or demand in the
same, similar or other circumstances.

Section 10.09 Merger, Consolidation or Sale of Assets of a Guarantor; Release of a Guarantor

     (a) To the extent that the Subsidiary Guarantee of a Guarantor has not been released in
accordance with the provisions of this Supplemental Indenture, such Guarantor may not sell or
otherwise dispose of all or substantially all of its properties or assets to, or consolidate with
or merge with or into, another Person (whether or not such Guarantor is the resulting, transferee
or surviving Person) other than the Company or another Guarantor, unless:

     (1) immediately after giving effect to such transaction, no Default or Event of Default
exists; and

     (2) either:

     (A) the Person acquiring the properties or assets in any such sale or other
disposition or the Person formed by or surviving any such consolidation or merger
(if other than such Guarantor) unconditionally assumes, pursuant to a supplemental
indenture substantially in the form of Exhibit C hereto, all the obligations
of such Guarantor under this Supplemental Indenture, the Securities and its
Subsidiary Guarantee on terms set forth therein; or

     (B) the Net Proceeds of such sale or other disposition are applied in
accordance with Section 4.07.

     (b) The Subsidiary Guarantee of a Guarantor shall be automatically and unconditionally
released:

     (1) in connection with any sale or other disposition of all or substantially all of the
properties or assets of such Guarantor (including by way of merger or consolidation) to a
Person that is not (either before or after giving effect to such transaction) a Restricted
Subsidiary of the Company, if the sale or other disposition complies with Section
4.07;

     (2) in connection with any sale or other disposition of all of the Capital Stock of
such Guarantor to a Person that is not (either before or after giving effect to such
transaction) a Restricted Subsidiary of the Company, if the sale or other disposition
complies with Section 4.07;

     (3) if such Guarantor is a Restricted Subsidiary and the Company designates such
Guarantor as an Unrestricted Subsidiary in accordance with Section 4.09;

76

 

     (4) upon the exercise by the Company of its legal defeasance option or covenant
defeasance option in accordance with Section 8.01(b) or upon satisfaction and
discharge of this Supplemental Indenture in accordance with Section 8.01(a);

     (5) upon the liquidation or dissolution of such Guarantor provided that no Default or
Event of Default has occurred and is continuing; or

     (6) at any time after the occurrence of an Investment Grade Rating Event, such
Guarantor does not have outstanding Indebtedness, and it does not guarantee Indebtedness of
the Company or any other Guarantor, in each case in excess of a De Minimis Amount.

     (c) Upon delivery by the Company to the Trustee of an Officers’ Certificate to the effect that
any of the conditions described in clauses (1) — (6) of Section 10.09(b) has occurred, the
Trustee shall execute any supplemental indenture or other documents reasonably requested by the
Company in order to evidence the release of any Guarantor from its obligations under its Subsidiary
Guarantee and this Supplemental Indenture.

Indenture or the Subsidiary Guarantees or for any claim based on, in respect of, or by reason of,

pay interest on the principal amount of this Security at 6.750% per annum from March 1, 2011 until

authenticated between a record date referred to on the face hereof and the next succeeding Interest
Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided,
further, that the first Interest Payment Date shall be September 1, 2011. The Company will pay, to
the extent lawful, interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue principal and premium, if any, at the rate then in effect; it will pay,
to the extent lawful, interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace
periods) from time to time on demand at the same rate as on overdue principal. Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

     2. Method of Payment. The Company will pay interest on the Securities (except Defaulted
Interest) to the Persons who are registered Holders of Securities at the close of business on the
February 15 or August 15 next preceding the Interest Payment Date, even if such Securities are
canceled after such record date and on or before such Interest Payment Date, except as provided in
Section 2.11 of the Supplemental Indenture with respect to Defaulted Interest. The
Securities will be payable as to principal, premium, if any, and interest at the office or agency

(expressed as percentages of the principal amount) plus accrued and unpaid interest on the
Securities, if any, to the applicable Redemption Date, if redeemed during the 12-month

(i) at least 65% of the aggregate principal amount of the Securities (including any
Additional Securities) originally issued under the Supplemental Indenture remains

within 180 days of the date of the closing of the related Equity Offering.

     (c) In addition, at any time and from time to time prior to March 1, 2016, the Company

     (i) 100% of the principal amount thereof, plus

     (ii) the Applicable Premium, plus

     (d) If Holders of not less than 95% in aggregate principal amount of the outstanding
Securities validly tender and do not withdraw such Securities in a Change of Control Offer

Securities validly

A-3

 

tendered and not withdrawn by such Holders, the Company or such third party will have
the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30
days following such purchase pursuant to the Change of Control Offer, to redeem all
Securities that remain outstanding following such purchase at a Redemption Price in cash
equal to the applicable Change of Control Payment plus, to the extent not included in the
Change of Control Payment, accrued and unpaid interest thereon to the Redemption Date.

     6. Denominations, Transfer, Exchange. The Securities are in registered form without coupons
in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The
transfer of Securities may be registered and Securities may be exchanged as provided in the
Supplemental Indenture. The Registrar or the Trustee may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay
any transfer tax or similar governmental charge or other fee required by law and payable in
connection therewith. The Company need not exchange or register the transfer of any Security or
portion of a Security selected for redemption, except for the unredeemed portion of any Security
being redeemed in part. Also, the Company need not exchange or register the transfer of any
Securities for a period of 15 days before the day of any selection of Securities to be redeemed or
during the period between a record date and the corresponding Interest Payment Date.

     If this is a Global Security, this Security represents the aggregate principal amount of
outstanding Securities from time to time endorsed hereon, and the aggregate principal amount of
outstanding Securities represented by this Security may from time to time be reduced or increased,
as appropriate, to reflect exchanges and redemptions in accordance with the Supplemental Indenture.

     7. Persons Deemed Owners. The registered Holder of a Security may be treated as its owner for
all purposes.

     8. Amendment, Supplement and Waiver. Subject to certain exceptions, the Supplemental
Indenture and the Securities may be amended or supplemented with the written consent of the Holders
of at least a majority in outstanding principal amount of the Securities, and any existing Default
or compliance with any provision of the Supplemental Indenture or the Securities may be waived with
the written consent of the Holders of at least a majority in outstanding principal amount of the
Securities. Without the consent of any Holder of a Security, the Supplemental Indenture, the
Subsidiary Guarantees or the Securities may be amended or supplemented (a) to cure any ambiguity,
defect or inconsistency, (b) to provide for uncertificated Securities in addition to or in place of
certificated Securities, (c) to provide for the assumption of the Company’s or a Guarantor’s

qualifying the Supplemental Indenture under the Trust Indenture Act or maintaining such
qualification, (f) to add or release Guarantors in compliance with the Supplemental Indenture, to

Guarantees in accordance with the Supplemental Indenture.

Securities may be declared due and payable in the manner and with the effect provided in the
Supplemental Indenture.
