ARTICLE II

THE SECURITIES

     SECTION 2.01. Form and Dating.

          (a) General. The Securities, any notations thereon relating to the Guarantees and the
Trustee’s certificate of authentication shall be substantially in the form of Exhibit A to this
Indenture, the terms of which are hereby incorporated into this Indenture. The Securities may have
notations, legends or endorsements required by law, securities exchange rule, the Company’s
certificate of incorporation, bylaws, agreements to which the Company is subject, if any, or usage,
provided that any such notation, legend or endorsement is in a form acceptable to the Company. Each
Security shall be dated the date of its authentication. The Securities shall be in registered form
without coupons and issued only 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 Indenture and, to the extent applicable, the Company, the
Guarantor and the Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions and to be bound thereby. However, to the extent any provision of any
Security conflicts with the express provisions of this Indenture, the provisions of this 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.

          (c) Regulation S Global Securities. Any Securities offered and sold in reliance on Regulation
S shall be issued initially in the form of a Regulation S Global Security, which shall be deposited
on behalf of the purchasers of the Securities represented thereby with the Securities Custodian,
and registered in the name of the Depositary or the nominee of the Depositary for the accounts of
designated agents holding on behalf of Euroclear or Clearstream, duly executed by the Company and
authenticated by the Trustee as hereinafter provided. Prior to the expiration of the Restricted
Period, any resale or transfer of beneficial interests in a Regulation S Global Security to U.S.
Persons shall not be permitted unless such resale or transfer is made pursuant to Rule 144A or
Regulation S.

10

 

          (d) 144A Global Securities. Any Securities offered and sold in reliance on Rule 144A shall be
issued initially in the form of a 144A Global Security, which shall be deposited on behalf of the
purchasers of the Securities represented thereby with the Securities Custodian, and registered in
the name of the Depositary or the nominee of the Depositary, duly executed by the Company and
authenticated by the Trustee as hereinafter provided.

          (e) 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).

     SECTION 2.02. Execution and Authentication. One Officer of the Company shall sign the
Securities on behalf of the Company by manual or facsimile signature. The Company’s seal may be
(but shall not be required to be) impressed, affixed, imprinted or reproduced on the Securities and
may be in facsimile form.

     If an Officer of the Company whose signature is on this Indenture or a Security no longer
holds that office at the time the Trustee authenticates such Security or at any time thereafter,
the Security shall be valid nevertheless.

     A Security shall not be entitled to any benefit under this Indenture or be valid or obligatory
for any purpose until authenticated by the manual signature of an authorized signatory of the
Trustee, which signature shall be conclusive evidence that the Security has been authenticated
under this Indenture.

     The Trustee shall authenticate and deliver: (1) Initial Securities for original issue in an
aggregate principal amount of $575,000,000, (2) if and when issued, Additional Securities (which
may be issued in either a registered or a private offering under the Securities Act) and (3)
Exchange Securities for issue only in an exchange offer pursuant to a Registration Rights
Agreement, and only in exchange for Initial Securities or Additional Securities of an equal
principal amount, 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 and whether they are to bear the Private Placement Legend. The Company may
issue Additional Securities under this Indenture subsequent to the Issue Date, provided 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. In authenticating such
Securities, the Trustee shall be entitled to receive, and shall be entitled to rely upon, an
Opinion of Counsel substantially to the effect that such Securities, when authenticated and
delivered by the Trustee and issued by the Company in the manner and subject to any conditions
specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the
Company enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent
transfer, reorganization, moratorium and similar laws of general applicability relating to or
affecting creditors’ rights and to general equity principles.

     The aggregate principal amount of Securities outstanding at any time may not exceed the
aggregate principal amount of Securities authorized for issuance by the Company pursuant to such
written orders of the Company, except as provided in Section 2.07. Subject to the

11

 

foregoing, the aggregate principal amount of Securities that may be issued under this
Indenture shall not be limited.

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

     SECTION 2.03. Registrar and Paying Agent. The Company shall maintain in the continental
United States an office or agency where Securities may be presented for registration of transfer or
exchange (“Registrar”) and an office or agency where Securities may be presented for payment
(“Paying Agent”). The Registrar shall keep a register of the Securities and of their transfer and
exchange. The Company may appoint one or more co-registrars and one or more additional paying
agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any
additional paying agent.

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

     The Company initially appoints Wells Fargo Bank, National Association, 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 The City of 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 The City of 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 The City
of New York.

     The immunities, protections and exculpations available to the Trustee under this Indenture
shall also be available to each Agent, and the Company’s obligations under Section 6.07 to
compensate and indemnify the Trustee shall extend likewise to each Agent.

     The Company initially appoints The Depository Trust Company (“DTC”) to act as Depositary with
respect to each Global Security.

     SECTION 2.04. Paying Agent to Hold Money in Trust. The Company shall require each Paying
Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the
benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal
of or premium, if any, Additional Amounts, if any, or interest on the Securities, whether such
money shall have been paid to it by the Company or the Guarantor, and

12

 

will notify the Trustee of any default by the Company or the Guarantor in making any such
payment. While any such default continues, the Trustee may require a Paying Agent to pay all money
held by it to the Trustee and to account for any funds disbursed. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee and to account for any funds
disbursed. Upon payment over to the Trustee and upon accounting for any funds disbursed, the Paying
Agent (if other than the Company) shall have no further liability for the money. If the Company or
a Subsidiary of the Company acts as Paying Agent, it shall segregate and hold in a separate trust
fund for the benefit of the Holders all money held by it as Paying Agent.

     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 and shall
otherwise comply with TIA Section 312(a). If the Trustee is not the Registrar, the Company shall
furnish to the Trustee 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, and the Company shall
otherwise comply with TIA Section 312(a).

     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. 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 of its decision to exchange the Global Securities for Definitive
Securities; provided that in no event shall the Regulation S Global Security be exchanged by
the Company for Definitive Securities prior to the expiration of the Restricted Period; or

          (3) any such owner requests (through a Participant or an 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.

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,

13

 

the Guarantor 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
Guarantor, 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 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 Indenture and the Applicable Procedures. Transfers of
beneficial interests in the Global Securities also shall require compliance with either
subparagraph (1) or (2) below, as applicable, as well as one or more of the other following
provisions of this Section 2.06, as applicable:

          (1) Transfer of Beneficial Interests in the Same Global Security. Beneficial interests
in any Restricted Global Security may be transferred to Persons who take delivery thereof in
the form of a beneficial interest in the same Restricted Global Security in accordance with
the transfer restrictions set forth in the Private Placement Legend; provided, however, that
prior to the expiration of the Restricted Period, (A) transfers of beneficial interests in
the Regulation S Global Security may not be to a U.S. Person or for the account or benefit
of a U.S. Person (other than an Initial Purchaser) and (B) such beneficial interests may be
held only through Euroclear or Clearstream (as Indirect Participants in the Depositary).
Beneficial interests in any Unrestricted Global Security may be transferred to Persons who
take delivery thereof in the form of a beneficial interest in such Unrestricted Global
Security. No written orders or instructions shall be required to be delivered to the
Registrar to effect the transfers described in the preceding sentence of this Section
2.06(b)(1).

          (2) All Other Transfers and Exchanges of Beneficial Interests in Global Securities. In
connection with all transfers and exchanges of beneficial interests that are not subject to
Section 2.06(b)(1) above, the transferor of such beneficial interest must deliver to the
Registrar either:

     (A) (i) a written order from a Participant or an Indirect Participant given to
the Depositary in accordance with the Applicable Procedures directing the Depositary
to credit or cause to be credited a beneficial interest in another Global Security
in an amount equal to the beneficial interest to be transferred or exchanged; and

          (ii) instructions given in accordance with the Applicable Procedures containing
information regarding the Participant account to be credited with such increase; or

     (B) (i) a written order from a Participant or an Indirect Participant given to
the Depositary in accordance with the Applicable Procedures directing the Depositary
to cause to be issued a Definitive Security in an amount equal to the beneficial
interest to be transferred or exchanged; and

14

 

          (ii) instructions given by the Depositary to the Registrar containing
information regarding the Person in whose name such Definitive Security shall be
registered to effect the transfer or exchange referred to in Section
2.06(b)(2)(B)(i) above; provided that in no event shall Definitive Securities be
issued upon the transfer or exchange of beneficial interests in the Regulation S
Global Security prior to the expiration of the Restricted Period.

Upon consummation of a Registered Exchange Offer by the Company in accordance with Section 2.06(f),
the requirements of this Section 2.06(b)(2) shall be deemed to have been satisfied upon receipt by
the Registrar of the instructions contained in the Letter of Transmittal delivered by the Holder of
such beneficial interests in the Restricted Global Securities (or transmitted to the Registrar via
the Depositary’s book-entry system). Upon satisfaction of all of the requirements for transfer or
exchange of beneficial interests in Global Securities contained in this Indenture, the Securities
or otherwise applicable under the Securities Act, the principal amount of each relevant Global
Security shall be adjusted pursuant to Section 2.06(h).

          (3) Transfer of Beneficial Interests to Another Restricted Global Security. A
beneficial interest in any Restricted Global Security may be transferred to a Person who
takes delivery thereof in the form of a beneficial interest in another Restricted Global
Security if the transfer complies with the requirements of Section 2.06(b)(2) above and the
Registrar receives the following:

     (A) if the transferee will take delivery in the form of a beneficial interest
in the 144A Global Security, then the transferor must deliver a certificate in the
form of Exhibit B hereto, including the certifications in item (1) thereof; and

     (B) if the transferee will take delivery in the form of a beneficial interest
in the Regulation S Global Security, then the transferor must deliver a certificate
in the form of Exhibit B hereto, including the certifications in item (2) thereof,
and if such transfer occurs prior to the expiration of the Restricted Period, then
the transferee must hold such beneficial interest through either Euroclear or
Clearstream (as Indirect Participants in the Depositary).

          (4) Transfer and Exchange of Beneficial Interests in a Restricted Global Security for
Beneficial Interests in the Unrestricted Global Security. A beneficial interest in any
Restricted Global Security may be exchanged by any holder thereof for a beneficial interest
in an Unrestricted Global Security or transferred to a Person who takes delivery thereof in
the form of a beneficial interest in an Unrestricted Global Security if the exchange or
transfer complies with the requirements of Section 2.06(b)(2) above:

     (A) such exchange or transfer is effected pursuant to a Registered Exchange
Offer in accordance with the applicable Registration Rights Agreement and the holder
of the beneficial interest to be transferred, in the case of an exchange, or the
transferee, in the case of a transfer, certifies in the applicable Letter of
Transmittal (or via the Depositary’s book-entry system) that it is not (i) a
broker-dealer, (ii) a Person participating in the distribution of the Exchange

15

 

Securities or (iii) a Person who is an affiliate (as defined in Rule 144) of
the Company;

     (B) such transfer is effected pursuant to a Shelf Registration Statement in
accordance with the applicable Registration Rights Agreement;

     (C) such transfer is effected by an Exchanging Dealer pursuant to an Exchange
Offer Registration Statement in accordance with the applicable Registration Rights
Agreement; or

     (D) the Registrar receives the following:

          (i) if the holder of such beneficial interest in a Restricted Global Security
proposes to exchange such beneficial interest for a beneficial interest in an
Unrestricted Global Security, a certificate from such holder in the form of Exhibit
C hereto, including the certifications in item (1)(a) thereof; or

          (ii) if the holder of such beneficial interest in a Restricted Global Security
proposes to transfer such beneficial interest to a Person who shall take delivery
thereof in the form of a beneficial interest in an Unrestricted Global Security, a
certificate from such holder in the form of Exhibit B hereto, including the
certifications in item (4) thereof;

and, in each such case set forth in this subparagraph (D), if the Registrar so
requests or if the Applicable Procedures so require, an Opinion of Counsel in form
reasonably acceptable to the Registrar to the effect that such exchange or transfer
is in compliance with the Securities Act and state “blue sky” laws and that the
restrictions on transfer contained herein and in the Private Placement Legend are no
longer required in order to maintain compliance with the Securities Act.

If any such transfer is effected pursuant to subparagraph (B) or (D) above at a time when an
Unrestricted Global Security has not yet been issued, the Company shall issue and, upon
receipt of a written order in accordance with Section 2.02 hereof, the Trustee shall
authenticate one or more Unrestricted Global Securities in an aggregate principal amount
equal to the aggregate principal amount of beneficial interests transferred pursuant to
subparagraph (B) or (D) above.

          (5) Exchange or Transfer Prohibited. Beneficial interests in an Unrestricted Global
Security cannot be exchanged for, or transferred to Persons who take delivery thereof in the
form of, a beneficial interest in a Restricted Global Security.

          (c) Transfer or Exchange of Beneficial Interests for Definitive Securities.

          (1) Beneficial Interests in Restricted Global Securities to Restricted Definitive
Securities. If any holder of a beneficial interest in a Restricted Global Security proposes
to exchange such beneficial interest for a Restricted Definitive Security or to transfer
such beneficial interest to a Person who takes delivery thereof in the form of a

16

 

Restricted Definitive Security, then, upon receipt by the Registrar of the following
documentation:

     (A) if the holder of such beneficial interest in a Restricted Global Security
proposes to exchange such beneficial interest for a Restricted Definitive Security,
a certificate from such holder in the form of Exhibit C hereto, including the
certifications in item (2)(a) thereof;

     (B) if such beneficial interest is being transferred to a QIB in accordance
with Rule 144A, a certificate to the effect set forth in Exhibit B hereto, including
the certifications in item (1) thereof; or

     (C) if such beneficial interest is being transferred to a non-U.S. Person in an
offshore transaction in accordance with Rule 904, a certificate to the effect set
forth in Exhibit B hereto, including the certifications in item (2) thereof,

the Registrar shall cause the aggregate principal amount of the applicable Global Security
to be reduced accordingly pursuant to Section 2.06(h), and the Company shall execute and the
Trustee shall 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 in a Restricted Global Security pursuant to this Section
2.06(c) shall be registered in such name or names and in such authorized denomination or
denominations as the holder of such beneficial interest shall instruct the Registrar through
instructions from the Depositary and the Participant or Indirect Participant. The Trustee
shall deliver such Definitive Securities to the Persons in whose names such Securities are
so registered. Any Definitive Security issued in exchange for a beneficial interest in a
Restricted Global Security pursuant to this Section 2.06(c)(1) shall bear the Private
Placement Legend and shall be subject to all restrictions on transfer contained therein.
Notwithstanding Sections 2.06(c)(1)(A) and (C), a beneficial interest in the Regulation S
Global Security may not be exchanged for a Definitive Security or transferred to a Person
who takes delivery thereof in the form of a Definitive Security prior to the expiration of
the Restricted Period, except in the case of a transfer pursuant to an exemption from the
registration requirements of the Securities Act other than Rule 904.

          (2) Beneficial Interests in Restricted Global Securities to Unrestricted Definitive
Securities. A holder of a beneficial interest in a Restricted Global Security may exchange
such beneficial interest for an Unrestricted Definitive Security or may transfer such
beneficial interest to a Person who takes delivery thereof in the form of an Unrestricted
Definitive Security only if:

     (A) such exchange or transfer is effected pursuant to a Registered Exchange
Offer in accordance with the applicable Registration Rights Agreement and the holder
of such beneficial interest, in the case of an exchange, or the transferee, in the
case of a transfer, certifies in the applicable Letter of Transmittal (or via the
Depositary’s book-entry system) that it is not (i) a broker-dealer, (ii) a

17

 

Person participating in the distribution of the Exchange Securities or (iii) a
Person who is an affiliate (as defined in Rule 144) of the Company;

     (B) such transfer is effected pursuant to a Shelf Registration Statement in

proposes to exchange such beneficial interest for an Unrestricted Definitive
Security, a certificate from such holder in the form of Exhibit C hereto, including
the certifications in item (1)(b) thereof; or

          (ii) if the holder of such beneficial interest in a Restricted Global Security
proposes to transfer such beneficial interest to a Person who shall take delivery

holder in the form of Exhibit B hereto, including the certifications in item (4)
thereof;

Securities Act and state “blue sky” laws and that the restrictions on transfer contained
herein and in the Private Placement Legend are no longer required in order to maintain
compliance with the Securities Act.

          (3) Beneficial Interests in Unrestricted Global Securities to Unrestricted Definitive
Securities. If any holder of a beneficial interest in an Unrestricted 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)(2)(B), the
Registrar shall cause the aggregate principal amount of the applicable Global Security to be
reduced accordingly pursuant to Section 2.06(h), and the Company shall execute and the
Trustee shall 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)(3) shall be registered
in such name or names and in such authorized denomination or denominations as the holder of
such beneficial interest shall instruct the Registrar through instructions from the
Depositary and the Participant or Indirect Participant. The Trustee shall deliver such
Definitive Securities to the Persons in whose names such Securities are so registered. Any
Definitive Security issued in exchange for a beneficial interest pursuant to this Section
2.06(c)(3) shall not bear the Private Placement Legend.

18

 

          (d) Transfer and Exchange of Definitive Securities for Beneficial Interests.

          (1) Restricted Definitive Securities to Beneficial Interests in Restricted Global
Securities. If any Holder of a Restricted Definitive Security proposes to exchange such
Security for a beneficial interest in a Restricted Global Security or to transfer such
Restricted Definitive Security to a Person who takes delivery thereof in the form of a
beneficial interest in a Restricted Global Security, then, upon receipt by the Registrar of
the following documentation:

such Security for a beneficial interest in a Restricted Global Security, a
certificate from such Holder in the form of Exhibit C hereto, including the

     (B) if such Restricted Definitive Security is being transferred to a QIB in
accordance with Rule 144A, a certificate to the effect set forth in Exhibit B

thereof,

the Trustee shall cancel the Restricted Definitive Security, the Registrar shall increase or

the appropriate Restricted Global Security, in the case of clause (B) above, the 144A Global
Security, and in the case of clause (C) above, the Regulation S Global Security.

          (2) Restricted Definitive Securities to Beneficial Interests in Unrestricted Global
Securities. A Holder of a Restricted Definitive Security may exchange such Security for a
beneficial interest in an Unrestricted Global Security or transfer such Restricted
Definitive Security to a Person who takes delivery thereof in the form of a beneficial
interest in an Unrestricted Global Security only if:

     (A) such exchange or transfer is effected pursuant to a Registered Exchange
Offer in accordance with applicable Registration Rights Agreement and the Holder, in
the case of an exchange, or the transferee, in the case of a transfer, certifies in
the applicable Letter of Transmittal (or via the Depositary’s book-entry system)

of the Exchange Securities or (iii) a Person who is an affiliate (as defined in Rule
144) of the Company;

to the Registrar to the effect that such exchange or transfer is in compliance with the
Securities Act and state “blue sky” laws and that the restrictions on transfer contained
herein and in the Private Placement Legend are no longer required in order to maintain
compliance with the Securities Act.

Upon satisfaction of the conditions of any of the subparagraphs in this Section 2.06(d)(2),
the Trustee shall cancel the Definitive Securities and the Registrar shall increase or cause
to be increased the aggregate principal amount of the Unrestricted Global Security.

          (3) Unrestricted Definitive Securities to Beneficial Interests in Unrestricted Global
Securities. A Holder of an Unrestricted Definitive Security may exchange such Security for

Unrestricted Global Security at any time. Upon receipt of a request for such an exchange or
transfer, the Trustee shall cancel the applicable Unrestricted Definitive Security and the
Registrar shall increase or cause to be increased the aggregate principal amount of one of
the Unrestricted Global Securities.

     If any such exchange or transfer from a Definitive Security to a beneficial interest is
effected pursuant to subparagraphs (2)(B), (2)(D) or (3) of this Section 2.06(d) at a time when an
Unrestricted Global Security has not yet been issued, the Company shall issue and, upon receipt of
an Authentication Order in accordance with Section 2.02, the Trustee shall authenticate one or more
Unrestricted Global Securities in an aggregate principal amount equal to the principal amount of
Definitive Securities so transferred.

          (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. In addition, the

20

 

requesting Holder shall provide any additional certifications, documents and information, as
applicable, required pursuant to the following provisions of this Section 2.06(e).

          (1) Restricted Definitive Securities to Restricted Definitive Securities. Any
Restricted Definitive Security may be transferred to and registered in the name of Persons
who take delivery thereof in the form of a Restricted Definitive Security if the Registrar

          (2) Restricted Definitive Securities to Unrestricted Definitive Securities. Any
Restricted Definitive Security may be exchanged by the Holder thereof for an Unrestricted
Definitive Security or transferred to a Person or Persons who take delivery thereof in the
form of an Unrestricted Definitive Security if:

     (A) such exchange or transfer is effected pursuant to a Registered Exchange
Offer in accordance with the applicable Registration Rights Agreement and the

in the distribution of the Exchange Securities or (iii) a Person who is an affiliate
(as defined in Rule 144) of the Company;

     (B) any such transfer is effected pursuant to a Shelf Registration Statement in

     (D) the Registrar receives the following:

          (i) if the Holder of such Restricted Definitive Securities proposes to exchange
such Securities for an Unrestricted Definitive Security, a certificate from such
Holder in the form of Exhibit C hereto, including the certifications in item (1)(d)
thereof; or

21

 

          (ii) if the Holder of such Restricted Definitive Security proposes to transfer
such Securities to a Person who shall take delivery thereof in the form of an
Unrestricted Definitive Security, a certificate from such Holder in the form of
Exhibit B hereto, including the certifications in item (4) thereof;

and, in each such case set forth in this subparagraph (D), if the Registrar so requests, an
Opinion of Counsel in form reasonably acceptable to the Registrar to the effect that such
exchange or transfer is in compliance with the Securities Act and state “blue sky” laws and
that the restrictions on transfer contained herein and in the Private Placement Legend are
no longer required in order to maintain compliance with the Securities Act.

          (3) Unrestricted Definitive Securities to Unrestricted Definitive Securities. A Holder
of Unrestricted Definitive Securities may transfer such Securities to a Person who takes
delivery thereof in the form of an Unrestricted Definitive Security. Upon receipt of a
request to register such a transfer, the Registrar shall register the Unrestricted
Definitive Security pursuant to the instructions from the Holder thereof.

          (f) Registered Exchange Offer. Upon the occurrence of a Registered Exchange Offer in
accordance with the applicable Registration Rights Agreement, the Company shall issue and, upon
receipt of a written order in accordance with Section 2.02, the Trustee shall authenticate:

          (1) one or more Unrestricted Global Securities in an aggregate principal amount equal

tendered for acceptance by Persons that certify in the applicable Letters of Transmittal (or
via the Depositary’s book-entry system), among other things, that (A) they are not
broker-dealers, (B) they are not participating in a distribution of the Exchange Securities
and (C) they are not affiliates (as defined in Rule 144) of the Company, and accepted for
exchange in the Registered Exchange Offer; and

          (2) Unrestricted Definitive Securities in an aggregate principal amount equal to the
principal amount of any Restricted Definitive Securities accepted for exchange in the
Registered Exchange Offer.

     Concurrently with the issuance of such Securities, the Registrar shall cause the aggregate
principal amount of the applicable Restricted Global Securities to be reduced accordingly, and the
Company shall execute and the Trustee shall authenticate, and deliver to the Persons designated by
the Holders of any Definitive Securities so accepted, Unrestricted Definitive Securities in the
appropriate principal amount.

          (g) Legends. The following legends shall appear on the face of all Global Securities and
Definitive Securities issued under this Indenture unless specifically stated otherwise in the
applicable provisions of this Indenture.

          (1) Private Placement Legend.

          (h) 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 2.11. 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.

25

 

          (i) 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 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 2.10, 8.05 and 10.06).

          (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 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 beginning at the
opening of business 15 days before the day of mailing of a notice of redemption under
Section 10.03 and ending at the close of business on such day or (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.

          (5) Prior to the due presentation for registration of transfer of any Security, the
Company, the 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 any payment on such Security and for all other purposes whatsoever,
whether or not such Security is overdue, and none of the Company, the Guarantor, 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 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. If a mutilated Security is surrendered to the Registrar
or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully
taken, the Company shall issue and the Trustee shall authenticate a replacement Security if the
requirements of Section 8-405 of the Uniform Commercial Code are met, such that the Securityholder
(a) satisfies the Company or the Trustee within a reasonable time after such Securityholder has
notice of such loss, destruction or wrongful taking and the Registrar

26

 

does not register a transfer prior to receiving such notification, (b) makes such request to
the Company or Trustee prior to the Security being acquired by a protected purchaser as defined in
Section 8-303 of the Uniform Commercial Code (a “protected purchaser”) and (c) satisfies any other
reasonable requirements of the Trustee. If required by the Trustee or the Company, such Holder
must furnish an indemnity bond that is sufficient in the judgment of the Trustee and the Company to
protect the Company, the Trustee, any Agent or any authenticating agent from any loss which any of
them may suffer if a Security is replaced. The Company and the Trustee may charge for their
expenses in replacing a Security. If, after the delivery of such replacement Security, a protected
purchaser of the original Security in lieu of which such replacement Security was issued presents
for payment or registration such original Security, the Trustee shall be entitled to recover such
replacement Security from the Person to whom it was delivered or any Person taking therefrom,
except a protected purchaser, and shall be entitled to recover upon the security or indemnity
provided therefor to the extent of any loss, damage, cost or expense incurred by the Trustee or the
Company in connection therewith. Every replacement Security is a contractual obligation of the
Company.

     In case any such mutilated, destroyed, lost or wrongfully taken 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.

     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 wrongfully taken Securities.

     SECTION 2.08. Outstanding Securities. The Securities outstanding at any time are all the
Securities authenticated by the Trustee except for those canceled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Security effected by the Trustee
hereunder and those described in this Section 2.08 as not outstanding; provided, however, that in
determining whether the Holders of the requisite principal amount of outstanding Securities are
present at a meeting of Holders of Securities for quorum purposes or have consented to or voted in
favor of any request, demand, authorization, direction, notice, consent, waiver, amendment or
modification hereunder, Securities held for the account of the Company or any of its Affiliates
shall be disregarded and deemed not to be outstanding, except that in determining whether the
Trustee shall be protected in making such a determination or relying upon any such quorum, consent
or vote, only Securities which a Responsible Officer of the Trustee actually knows to be so owned
shall be so disregarded.

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

     If the principal amount of any Security is considered paid under Section 3.01, it ceases to be
outstanding and interest on it ceases to accrue.

     SECTION 2.09. [Reserved.]

27

 

     SECTION 2.10. 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. Until so exchanged, temporary Securities shall in all respects be entitled to the same
benefits under this Indenture as Definitive Securities.

     SECTION 2.11. Cancellation. The Company or the Guarantor at any time may deliver Securities
to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee
shall cancel all Securities surrendered for registration of transfer, exchange, payment,
replacement or cancellation. All canceled Securities held by the Trustee shall be disposed of in
accordance with the usual disposal procedures of the Trustee. The Company may not issue new
Securities to replace Securities that have been paid or that have been delivered to the Trustee for
cancellation.

     SECTION 2.12. Defaulted Interest. If the Company defaults in a payment of interest on the
Securities, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful,
interest on the defaulted interest, in each case at the rate provided in the Securities and in the
manner provided in Section 3.01. The Company may pay the defaulted interest to the Persons who are
Holders on a subsequent special record date. At least 15 days before any special record date, the
Company (or the Trustee, in the name of and at the expense of the Company) shall mail to Holders a
notice that states the special record date, the related payment date and the amount of such
interest to be paid.

     SECTION 2.13. Persons Deemed Owners. The Company, the Guarantor, the Trustee, any Agent and
any authenticating agent may treat the Person in whose name any Security is registered as the owner
of such Security for the purpose of receiving payments of principal of or premium, if any,
Additional Amounts, if any, or interest on such Security and for all other purposes. None of the
Company, the Guarantor, the Trustee, any Agent or any authenticating agent shall be affected by any
notice to the contrary.

     SECTION 2.14. 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 that any such notice may state that no
representation is made as to the correctness of such numbers either as printed on the Securities or
as contained in any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Securities, and any such redemption shall not be affected by
any defect in or omission of such numbers. The Company will promptly notify the Trustee of any
change in any such number.

ARTICLE III

COVENANTS

     SECTION 3.01. Payment of Securities. The Company shall pay the principal of and premium, if
any, Additional Amounts, if any, and interest on the Securities on the dates and in

28

 

the manner provided in the Securities, this Indenture and, in the case of any Additional
Interest, the applicable Registration Rights Agreement. Principal, premium, if any, Additional
Amounts, if any, and interest shall be considered paid on the date due if the Paying Agent, other
than the Company or a Subsidiary of the Company, holds by 11:00 a.m., Eastern time, on that date
money deposited by or on behalf of the Company designated for and sufficient to pay all principal,
premium, if any, Additional Amounts, if any, and interest then due.

     Further, to the extent lawful, the Company shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue principal, premium, if any,
Additional Amounts, if any, and interest (without regard to any applicable grace period), from time
to time on demand at the rate then in effect on the Securities.

     All references in this Indenture, the Securities or the Guarantees to “interest” shall be
deemed to include Additional Interest unless the context otherwise requires. The Company shall
give the Trustee advance written notice of the amount of any Additional Interest that may be
payable with respect to the Securities.

     SECTION 3.02. Maintenance of Office or Agency. So long as any of the Securities shall remain
outstanding, the Company will, in accordance with Section 2.03, 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 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 The City of New York where any Definitive Securities may be
presented or surrendered for payment. The Company will give to the 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
Company hereby appoints the Trustee its agent to receive at the aforesaid office all such
surrenders, presentations, notices and demands.

     SECTION 3.03. SEC Reports; Financial Statements.

          (a) The Guarantor covenants and agrees, so long as any Securities are outstanding, to file
with the Trustee copies, within 15 days after the Guarantor is required to file the same with the
SEC, of the annual reports and of the information, documents and other reports (or copies of such
portions of any of the foregoing as the SEC may from time to time by rules and regulations
prescribe) which the Guarantor may be required to file with the SEC pursuant to Section 13 or
Section 15(d) of the Exchange Act; or, if the Guarantor is not required to file information,
documents or reports pursuant to either of such sections, then to file with the Trustee and the
SEC, in accordance with rules and regulations prescribed from time to time by

29

 

the SEC, such of the supplementary and periodic information, documents and reports, if any,
which may be required pursuant to Section 13 of the Exchange Act, in respect of a security listed
and registered on a national securities exchange as may be prescribed from time to time in such
rules and regulations.

          (b) At any time when neither the Guarantor nor the Company is subject to Section 13 or 15(d)
of the Exchange Act and the Securities are not freely transferable under the Securities Act, upon
the request of a Holder, the Guarantor and the Company will promptly furnish or cause to be
furnished the information specified under Rule 144A(d)(4) of the Securities Act to such Holder, or
to a prospective purchaser of a Security designed by such Holder, in order to permit compliance
with Rule 144A.

     SECTION 3.04. Compliance Certificate. The Company and the Guarantor shall deliver to the
Trustee, within 120 days after the end of each fiscal year of the Company, a statement signed by
two Officers of the Company (one of whom shall be the Chief Executive Officer, Chief Financial
Officer or Chief Accounting Officer of the Company) and two Officers of the Guarantor (one of whom
shall be the Chief Executive Officer, Chief Financial Officer or Chief Accounting Officer of the
Guarantor), which statement need not constitute an Officers’ Certificate, complying with TIA
Section 314(a)(4) and stating that in the course of performance by the signing Officers of the
Company and Officers of the Guarantor of their duties as such Officers, they would normally obtain
knowledge of the keeping, observing, performing and fulfilling by the Company and the Guarantor,
respectively, of their obligations under this Indenture, and further stating, as to each such
Officer signing such statement, that to the best of his knowledge, each of the Company and the
Guarantor has kept, observed, performed and fulfilled each and every covenant contained in this
Indenture and is not in default in the performance or observance of any of the terms, provisions
and conditions hereof (or, if a Default or Event of Default shall have occurred, describing all
such Defaults or Events of Default of which such Officer may have knowledge and what action the
Company or the Guarantor, as the case may be, are taking or proposes to take with respect thereto).

     SECTION 3.05. Corporate Existence. Subject to Article IV, each of the Company and the
Guarantor will do or cause to be done all things necessary to preserve and keep in full force and
effect its corporate existence, under the laws of its jurisdiction of incorporation or formation.

     SECTION 3.06. Waiver of Stay, Extension or Usury Laws. Each of the Company and the Guarantor
covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or
plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension
law or any usury law or other law, which would prohibit or forgive the Company or the Guarantor
from paying all or any portion of the principal of or premium, if any, Additional Amounts, if any,
or interest on the Securities as contemplated herein, wherever enacted, now or at any time
hereafter in force, or which may affect the covenants or the performance of this Indenture; and (to
the extent that they may lawfully do so) each of the Company and the Guarantor 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.

30

 

     SECTION 3.07. Limitation on Liens. So long as any Securities are outstanding, the Guarantor
will not, nor will it permit any Subsidiary to, issue, assume, guarantee or suffer to exist any
debt for money borrowed (“Debt”) if such Debt is secured by a mortgage, pledge, security interest
or lien (a “mortgage” or “mortgages”) upon any properties of the Guarantor or any Subsidiary or
upon any securities or indebtedness of any Subsidiary (whether such properties, securities or
indebtedness is now owned or hereafter acquired) without in any such case effectively providing
that the Securities shall be secured equally and ratably with (or prior to) such Debt, except that
the foregoing restrictions shall not apply to:

          (a) mortgages on any property acquired, constructed or improved by the Guarantor or any
Subsidiary (or mortgages on the securities of a special purpose Subsidiary which holds no material
assets other than the property being acquired, constructed or improved) after the date of this
Indenture which are created within 360 days after such acquisition (or in the case of property
constructed or improved, after the completion and commencement of commercial operation of such
property, whichever is later) to secure or provide for the payment of the purchase price or cost
thereof; provided that in the case of such construction or improvement the mortgages shall not
apply to any property owned by the Guarantor or any Subsidiary before such construction or
improvement other than (1) unimproved real property on which the property so constructed, or the
improvement, is located or (2) personal property which is so improved;

          (b) mortgages existing on the Issue Date, existing mortgages on property acquired (including
mortgages on any property acquired from a Person which is consolidated with or merged with or into
the Guarantor or a Subsidiary) or mortgages outstanding at the time any corporation, partnership or
other entity becomes a Subsidiary; provided that such mortgages shall only apply to property owned
by such corporation, partnership or other entity at the time it becomes a Subsidiary or that is
acquired thereafter other than from the Guarantor or another Subsidiary;

          (c) mortgages in favor of the Guarantor or any Subsidiary;

          (d) mortgages in favor of domestic or foreign governmental bodies to secure advances or other
payments pursuant to any contract or statute or to secure indebtedness incurred to finance the
purchase price or cost of constructing or improving the property subject to such mortgages,
including mortgages to secure Debt of the pollution control or industrial revenue bond type;

          (e) mortgages consisting of pledges or deposits by the Guarantor or any Subsidiary under
workers’ compensation laws, unemployment insurance laws or similar legislation, or good faith
deposits in connection with bids, tenders, contracts (other than for the payment of Debt) or leases
to which the Guarantor or any Subsidiary is a party, or deposits to secure public or statutory
obligations of the Guarantor or any Subsidiary or deposits of cash or United States government
bonds to secure surety or appeal bonds to which it is a party, or deposits as security for
contested taxes or import or customs duties or for the payment of rent, in each case incurred in
the ordinary course of business;

31

 

          (f) mortgages imposed by law, including carriers’, warehousemen’s, repairman’s, landlords’ and
mechanics’ liens, in each case for sums not yet due or being contested in good faith by appropriate
proceedings if a reserve or other appropriate provisions, if any, as shall be required by GAAP
shall have been made in respect thereof;

          (g) mortgages for taxes, assessments or other governmental charges that are not yet delinquent
or which are being contested in good faith by appropriate proceedings provided appropriate reserves
required pursuant to GAAP have been made in respect thereof;

          (h) mortgages in favor of issuers of surety or performance bonds or letters of credit or
bankers’ acceptances issued pursuant to the request of and for the account of the Guarantor or any
Subsidiary in the ordinary course of its business;

          (i) mortgages consisting of encumbrances, easements or reservations of, or rights of others
for, licenses, rights of way, sewers, electric lines, telegraph and telephone lines and other
similar purposes, or mortgages consisting of zoning or other restrictions as to the use of real
properties or mortgages incidental to the conduct of the business of the Guarantor or a Subsidiary
or to the ownership of its properties which do not materially adversely affect the value of said
properties or materially impair their use in the operation of the business of the Guarantor or a
Subsidiary;

          (j) mortgages arising by virtue of any statutory or common law provisions relating to bankers’
liens, rights of set-off or similar rights and remedies as to deposit accounts or other funds
maintained with a depository institution; provided that:

     (i) such deposit account is not a dedicated cash collateral account and is not
subject to restrictions against access by the Guarantor or any Subsidiary in excess
of those set forth by regulations promulgated by the Federal Reserve Board; and

     (ii) such deposit account is not intended by the Guarantor or any Subsidiary to
provide collateral to the depository institution;

          (k) mortgages arising from Uniform Commercial Code financing statement filings regarding
operating leases the Guarantor and its Subsidiaries enter into in the ordinary course of business;

          (l) any mortgage over goods (or any documents relating thereto) arising either in favor of a
bank issuing a form of documentary credit in connection with the purchase of such goods or by way
of retention of title by the supplier of such goods where such goods are supplied on credit,
subject to such retention of title, and in both cases where such goods are acquired in the ordinary
course of business;

          (m) any mortgage pursuant to any order of attachment, execution, enforcement, distraint or
similar legal process arising in connection with court proceedings; provided that such process is
effectively stayed, discharged or otherwise set aside within 30 days;

32

 

          (n) any lease, sublease and sublicense granted to any third party constituting a mortgage and
any mortgage pursuant to farm-in and farm-out agreements, operating agreements, development
agreements and any other similar arrangements, which are customary in the oil and gas industry or
in the ordinary course of business of the Guarantor or any Subsidiary; or

          (o) any extension, renewal or replacement (or successive extensions, renewals or
replacements), in whole or in part, of any mortgage referred to in the foregoing clauses (a)
through (n), inclusive; provided that the principal amount of Debt secured thereby shall not exceed
the principal amount of Debt so secured at the time of such extension, renewal or replacement, and
that such extension, renewal or replacement shall be limited to all or a part of the property which
secured the mortgage so extended, renewed or replaced (plus improvements in such property).

     In addition to the foregoing, the Guarantor and any Subsidiary may, without securing the
Securities, issue, assume or guarantee secured Debt that, with certain other Debt described in the
following sentence, does not exceed 10% of Consolidated Net Tangible Assets. The other Debt to be
aggregated for purposes of this exception is all Attributable Debt in respect of Sale and
Lease-Back Transactions of the Guarantor and its Subsidiaries under the exception in clause (e)(2)
of Section 3.09 existing at such time.

     SECTION 3.08. Payment of Additional Amounts. Unless otherwise required by Bermudan law,
neither the Company nor the Guarantor will deduct or withhold from payments made with respect to
the Securities and the Guarantees on account of any present or future Taxes. In the event that
either the Company or the Guarantor is required to withhold or deduct on account of any Taxes due
from any payment made under or with respect to the Securities or the Guarantees, as the case may
be, the Company or the Guarantor, as the case may be, will pay such additional amounts (“Additional
Amounts”) as may be necessary so that the net amount received by each Holder of Securities will
equal the amount that the Holder would have received if the Taxes had not been required to be
withheld or deducted; provided that no Additional Amounts will be payable with respect to a payment
made to a Holder (an “Excluded Holder”) to the extent: (i) that any Taxes would not have been so
imposed but for the existence of any present or former connection between the Holder and Bermuda,
other than the mere receipt of the payment, acquisition, ownership or disposition of such
Securities or the exercise or enforcement of rights under the Securities, the Guarantees or this
Indenture; (ii) of any estate, inheritance, gift, sales, transfer or personal property Taxes
imposed with respect to the Securities or any other Taxes payable other than by withholding or
deduction, except as described below or as otherwise provided in this Indenture; (iii) that any
such Taxes would not have been imposed but for the presentation of the Securities, where
presentation is required, for payment on a date more than 30 days after the date on which the
payment became due and payable or the date on which payment thereof is duly provided for, whichever
is later, except to the extent that the beneficiary or Holder thereof would have been entitled to
Additional Amounts had the Securities been presented for payment on any date during such 30-day
period; or (iv) that the Holder would not be liable or subject to such withholding or deduction of
Taxes but for the failure to make a valid declaration of non-residence or other similar claim for
exemption, if: (a) the making of the declaration or claim is required or imposed by statute,
treaty, regulation, ruling or administrative practice of the relevant taxing authority as a
precondition to an exemption from, or reduction in, the relevant Taxes; and (b) at least 60 days
prior to the first payment with respect to which the Company or

33

 

the Guarantor shall apply this clause (iv), the Company or the Guarantor shall have notified
all Holders of the Securities in writing that they shall be required to provide this declaration or
claim. The Company and the Guarantor shall also (i) withhold or deduct such Taxes as required; (ii)
remit the full amount of Taxes deducted or withheld to the relevant taxing authority in accordance
with all applicable laws; (iii) use reasonable efforts to obtain from each relevant taxing
authority imposing the Taxes certified copies of tax receipts evidencing the payment of any Taxes
deducted or withheld; and (iv) upon request, make available to the Holders of the Securities,
within 60 days after the date the payment of any Taxes deducted or withheld is due pursuant to
applicable law, certified copies of tax receipts evidencing such payment by the Company or the
Guarantor and, notwithstanding the Company’s or the Guarantor’s efforts to obtain the receipts, if
the same are not obtainable, other evidence of such payments.

     In addition, the Company or the Guarantor will pay any stamp, issue, registration, documentary
or other similar taxes and duties, including interest, penalties and additional amounts with
respect thereto, payable in Bermuda or the United States, or any political subdivision or taxing
authority of or in the foregoing with respect to the creation, issue, offering, enforcement,
redemption or retirement of the Securities or Guarantees.

     At least 30 days prior to each date on which any payment under or with respect to the
Securities is due and payable, if the Company or the Guarantor becomes obligated to pay Additional
Amounts with respect to such payment, the Company (or in respect of the Guarantees, the Guarantor)
shall deliver to the Trustee an Officers’ Certificate stating the fact that such Additional Amounts
will be payable, and the amounts so payable and will set forth such other information as is
necessary to enable the Trustee to pay such Additional Amounts to the Holders on the payment date.
Whenever in this Indenture there is mentioned, in any context, the payment of principal of and
premium, if any, Additional Amounts, if any, or interest (including defaulted interest) or any
other amount payable on or with respect to any of the Securities, such mention shall be deemed to
include mention of the payment of Additional Amounts provided for in this Section 3.08 to the
extent that, in such context, Additional Amounts are, were or would be payable in respect thereof
pursuant to the provisions of this Section 3.08 and express mention of the payment of Additional
Amounts in those provisions hereof shall not be construed as excluding Additional Amounts in those
provisions hereof where such express mention is not made (if applicable).

     If payments with respect of the Securities or the Guarantees become subject generally to the
taxing jurisdiction of any Territory or any political subdivision or taxing authority thereof or
therein having power to tax, other than or in addition to Bermuda or the United States or any
political subdivision or taxing authority therein or thereof having power to tax, immediately upon
becoming aware thereof the Company shall notify the Trustee of such event, and thereupon the
Company or the Guarantor, as the case may be, shall be obligated to pay Additional Amounts in
respect thereof on terms corresponding to the terms of the foregoing provisions of this Section
3.08 with the substitution for (or, as the case may be, in addition to) the references herein to
Bermuda or any political subdivision or authority therein or thereof having power to tax of
references to that other or additional Territory or any political subdivision or authority therein
or thereof having power to tax to whose taxing jurisdiction such payments shall have become subject
as aforesaid. The term “Territory” means for this purpose any jurisdiction in which the

34

 

Company or the Guarantor, as the case may be, is incorporated or in which it has its place of
central management or central control.

     The obligations of the Company and the Guarantor under this Section 3.08 shall survive the
termination of this Indenture and the payment of all amounts under or with respect to this
Indenture and the Securities.

     SECTION 3.09. Limitations on Sale and Lease-Back Transactions. So long as any Securities are
outstanding, the Guarantor will not, nor will it permit any Subsidiary to, enter into any Sale and
Lease-Back Transaction, other than any Sale and Lease-Back Transaction:

          (a) entered into within 360 days of the later of the acquisition or placing into service of
the property subject thereto by the Guarantor or such Subsidiary;

          (b) involving a lease of less than five years;

          (c) entered into in connection with an industrial revenue bond or pollution control financing;

          (d) between the Guarantor and/or one or more Subsidiaries;

          (e) as to which the Guarantor or such Subsidiary would be entitled to incur Debt secured by a
mortgage on the property to be leased in an amount equal to the Attributable Debt with respect to
such Sale and Lease-Back Transaction without equally and ratably securing the Securities (1) under
clauses (a) through (n) of Section 3.07 or (2) under the last paragraph of Section 3.07; or

          (f) as to which the Guarantor will apply an amount equal to the net proceeds from the sale of
the property so leased to (1) the retirement (other than any mandatory retirement), within 360 days
of the effective date of any such Sale and Lease-Back Transaction, of Securities or of Funded Debt
of the Guarantor or a Subsidiary or (2) the purchase or construction of other property, provided
that such property is owned by the Guarantor or a Subsidiary free and clear of all mortgages.

     SECTION 3.10. Change of Control Offer. Upon the occurrence of a Change of Control Triggering
Event, each Holder shall have the right to require the Company to purchase all or any part (equal
to $2,000 or an integral multiple of $1,000 in excess thereof) of such Holder’s Securities at a
purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid
interest, if any, up to, but not including, the date of purchase; provided, however, that if such
date of purchase 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 repurchased Securities are registered on such record date. Notwithstanding the
foregoing, the Company shall have no obligation to repurchase any Securities pursuant to this
Section 3.10 to the extent that the Company shall have exercised its right to redeem the Securities
pursuant to Section 10.07.

35

 

     For purposes of this Section 3.10, the term “Change of Control” means the occurrence of any
one of the following:

          (a) the sale, lease, transfer, conveyance or other disposition (other than by way of merger,
amalgamation or consolidation), in one or a series of related transactions, of all or substantially
all of the assets of the Guarantor and the Subsidiaries taken as a whole to any “person” (as that
term is used in Section 13(d)(3) of the Exchange Act) other than to the Guarantor or one or more of
the Subsidiaries or a combination thereof or a Person controlled by the Guarantor or one or more of
the Subsidiaries or a combination thereof;

          (b) the consummation of any transaction (including without limitation, any merger,
amalgamation or consolidation) the result of which is that any “person” (as that term is used in
Section 13(d)(3) of the Exchange Act) (other than any Subsidiary) becomes the “beneficial owner”
(as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than
50% of the outstanding Voting Stock of the Guarantor, measured by voting power rather than number
of shares (excluding a redomestication of the Guarantor); or

          (c) the first day on which the majority of the members of the Board of Directors of the
Guarantor cease to be Continuing Directors.

Notwithstanding the foregoing, a transaction shall not be deemed to involve a “Change of Control”
under clause (b) above if (i) the Guarantor becomes a direct or indirect wholly owned Subsidiary of
a holding company and (ii)(A) the direct or indirect holders of the Voting Stock of such holding
company immediately following such transaction are substantially the same as the holders of the
Voting Stock of the Guarantor immediately prior to such transaction or (B) immediately following
such transaction no “person” (as that term is used in Section 13(d)(3) of the Exchange Act) (other
than a holding company satisfying the requirements of this sentence) is the “beneficial owner” (as
defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50%
of the outstanding Voting Stock of such holding company, measured by voting power rather than
number of shares.

     For purposes of this Section 3.10, the term “Change of Control Triggering Event” means the
ratings of the Securities are lowered by at least two of the three Rating Agencies and the
Securities cease to be rated Investment Grade by at least two of the three Rating Agencies in any
case on any date during the period (the “Trigger Period”) commencing on the date of the first
public announcement by the Guarantor of any Change of Control (or pending Change of Control) and
ending 60 days following consummation of such Change of Control (which 60-day period will be
extended for so long as the rating of the notes is under publicly announced consideration for a
possible downgrade by any of the Rating Agencies). Notwithstanding the foregoing, no Change of
Control will be deemed to have occurred in connection with any particular Change of Control unless
and until such Change of Control has actually been consummated.

     Within 60 days following the date upon which the Change of Control Triggering Event has
occurred, or at the Company’s option, prior to any Change of Control but after the public
announcement of the transaction that constitutes or may constitute the Change of Control, except to
the extent that the Company shall have exercised its right to redeem the Securities pursuant to
Section 10.07, the Company shall mail a notice (a “Change of Control Offer”) to each Holder

36

 

with a copy to the Trustee, which notice will govern the terms of the Change of Control Offer,
stating:

          (1) that a Change of Control Triggering Event has occurred and that such Holder has the
right to require us to purchase such Holder’s Securities at a purchase price in cash equal
to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the
date of purchase (subject to the right of holders of record on a record date to receive
interest on the relevant Interest Payment Date as provided in the first paragraph of this
Section 3.10);

          (2) the circumstances regarding such Change of Control Triggering Event;

          (3) the purchase date (which shall be no earlier than 30 days nor later than 60 days
from the date such notice is mailed, other than as may be required by law) (such date, the
“Change of Control Payment Date”); and

          (4) the instructions that a Holder must follow in order to have its Securities
purchased.

     Holders of Securities electing to have Securities purchased pursuant to a Change of Control
Offer must surrender their Securities, with the form entitled “Option of Holder to Elect Purchase”
on the reverse of the Security completed, to the Paying Agent at the address specified in the
notice, or transfer their Securities to the Paying Agent by book-entry transfer pursuant to the
Applicable Procedures, prior to the close of business on the third Business Day prior to the Change
of Control Payment Date.

     On the Change of Control Payment Date, all Securities purchased by the Company under this
Section shall be delivered to the Trustee for cancellation, and the Company shall pay the purchase
price plus accrued and unpaid interest to the Holders entitled thereto.

     The Company may make a Change of Control Offer in advance of a Change of Control and the
Change of Control Payment Date, and its Change of Control Offer may be conditioned upon such
Change of Control, if a definitive agreement is in place for the Change of Control at the time of
making the Change of Control Offer.

     The Company shall have no obligation to make a Change of Control Offer if a third party makes
such an offer in the manner, at the times and otherwise in compliance with the requirements of this
Section 3.10 for such an offer made by the Company, and such third party purchases all Securities
properly tendered and not withdrawn under its offer.

     The Company shall comply, to the extent applicable, with the requirements of Section 14(e) of
the Exchange Act and any other securities laws or regulations in connection with the repurchase of
Securities pursuant to a Change of Control Offer. To the extent that the provisions of any
securities laws or regulations conflict with this Section 3.10, the Company shall comply with the
applicable securities laws and regulations and will not be deemed to have breached its obligations
by virtue thereof.

     SECTION 5.02. Acceleration. If an Event of Default (other than an Event of Default specified
in clause (iv) or (v) of Section 5.01) occurs and is continuing, the Trustee by notice to the
Company and the Guarantor, or by the Holders of at least 25% in aggregate principal amount of the
then outstanding Securities by written notice to the Company, the Guarantor and the Trustee, may
declare the principal of, premium, if any, Additional Amounts, if any, and accrued and unpaid
interest on all then outstanding Securities to be due and payable immediately. Upon any such
declaration the amounts due and payable on the Securities, as determined in accordance with the
next succeeding paragraph, shall be due and payable immediately. If an Event of

40

 

Default specified in clause (iv) or (v) of Section 5.01 occurs, the principal of, premium, if
any, Additional Amounts, if any, and interest on all Securities then outstanding shall ipso facto
become and be immediately due and payable without any declaration, notice or other act on the part
of the Trustee or any Holder.

     At any time after such an acceleration has occurred and before a judgment for payment of the
money due has been obtained by the Trustee as hereinafter in this Article V provided, the Holders
of a majority in aggregate principal amount of the outstanding Securities, by written notice to the
Company, the Guarantor and the Trustee, may rescind and annul such acceleration and its
consequences if:

          (1) the Company or the Guarantor has paid or deposited with the Trustee a sum
sufficient to pay:

     (A) the principal of and premium, if any, on any Securities which have become
due otherwise than by such declaration of acceleration and Additional Amounts, if
any, and any interest thereon at the rate or rates prescribed therefor in such
Securities or in this Indenture,

     (B) all overdue interest and Additional Amounts, if any, on all Securities,

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

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

          (2) all Events of Default, other than the non-payment of the principal of Securities
which have become due solely by such declaration of acceleration, have been cured or waived
as provided in Section 5.04.

     No such rescission shall affect any subsequent Event of Default or impair any right consequent
thereon.

     If the Maturity of the Securities is accelerated pursuant to this Section 5.02, 100% of the
principal amount thereof and premium, if any, shall become due and payable plus Additional Amounts,
if any, and accrued and unpaid interest to the date of payment.

     SECTION 5.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee
may pursue any available remedy to collect the payment of principal of, premium, if any, Additional
Amounts, if any, or interest on the Securities or to enforce the performance of any provision of
the Securities, the Guarantees or this Indenture.

     The Trustee may maintain a proceeding even if it does not possess any of the Securities or
does not produce any of them in the proceeding. A delay or omission by the Trustee or any

41

 

Holder in exercising any right or remedy accruing upon an Event of Default shall not impair
the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies
are cumulative to the extent permitted by law.

     SECTION 5.04. Waiver of Existing Defaults. Subject to Sections 5.07 and 8.02, the Holders of
a majority in aggregate principal amount of the Securities then outstanding by notice to the
Trustee may waive an existing Default or Event of Default and its consequences (including waivers
obtained in connection with a tender offer or exchange offer for the Securities or a solicitation
of consents in respect of the Securities, provided that in each case such offer or solicitation is
made to all Holders of the Securities then outstanding on equal terms), except (1) a continuing
Default or Event of Default in the payment of the principal of or premium, if any, Additional
Amounts, if any, or interest on the Securities or (2) a continuing Default in respect of a
provision that under Section 8.02 cannot be amended without the consent of each Holder affected.
Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom
shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall
extend to any subsequent or other Default or impair any right consequent thereon.

     SECTION 5.05. Control by Majority. The Holders of a majority in aggregate principal amount of
the Securities then outstanding may 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 it hereunder.
The Trustee, however, may refuse to follow any direction that conflicts with applicable law or this
Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders, or
that may involve the Trustee in personal liability; provided, however, that the Trustee may take
any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior
to taking any action hereunder, the Trustee shall be entitled to receive reasonable indemnification
satisfactory to it against all losses and expenses caused by taking or not taking such action
subject to the Trustee’s duty to act with the required standard of care during a default.

     SECTION 5.06. Limitations on Suits. Subject to Section 5.07, a Holder may pursue a remedy
with respect to this Indenture (including the Guarantees) or the Securities only if:

          (i) such Holder gives to the Trustee written notice of a continuing Event of
Default;

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

          (iii) such Holder or Holders furnish to the Trustee reasonable indemnity
satisfactory to the Trustee against any loss, liability or expense;

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

42

 

          (v) during such 60-day period the Holders of a majority in aggregate principal
amount of the Securities then outstanding do not give the Trustee a direction
inconsistent with the request.

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

     SECTION 5.07. Rights of Holders to Receive Payment. Notwithstanding any other provision of
this Indenture, the right of any Holder of a Security to receive payment of principal of and
premium, if any, Additional Amounts, if any, and interest on the Security, on or after the
respective due dates expressed in the Security, or to bring suit against the Company or the
Guarantor for the enforcement of any such payment on or after such respective dates, is absolute
and unconditional and shall not be impaired or affected without the consent of such Holder.

     SECTION 5.08. Collection Suit by Trustee. If an Event of Default specified in clause (i) or
(ii) of Section 5.01 occurs and is continuing, the Trustee is authorized to recover judgment in its
own name and as trustee of an express trust against the Company and the Guarantor (i) for the
amount of principal of and premium, if any, Additional Amounts, if any, and interest remaining
unpaid on any Securities and (ii) interest on overdue principal, premium, if any, Additional
Amounts, if any, and, to the extent lawful, interest on overdue interest, and such further amount
as shall be sufficient to cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

     SECTION 5.09. Trustee May File Proofs of Claim. The Trustee is authorized to file such proofs
of claim and other papers or documents and to take such actions, including participating as a
member, voting or otherwise, of any committee of creditors, as may be necessary or advisable 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 the Holders
allowed in any judicial proceedings relative to the Company and the Guarantor or their respective
creditors or properties and shall be entitled and empowered to collect, receive and distribute any
money or other property payable or deliverable on any such claims and any Custodian in any such
judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and
in the event that the Trustee shall consent to the making of such payments directly to the Holders,
to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 6.07. To the extent that the payment of any such compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 6.07 out of the estate in any such proceeding, shall be denied for any reason, payment of
the same shall be secured by a lien on, and shall be paid out of, any and all distributions,
dividends, money, securities and other properties which the Holders of the Securities may be
entitled to receive in such proceeding whether in liquidation or under any plan of reorganization
or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization,
arrangement, adjustment or composition affecting the Securities or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

43

 

     SECTION 5.10. Priorities. If the Trustee collects any money pursuant to this Article V, it
shall pay out the money in the following order:

First: to the Trustee for amounts due under Section 6.07;

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

Third: to the Company and the Guarantor.

     The Trustee, upon prior written notice to the Company and the Guarantor, may fix a record date
and payment date for any payment to Holders pursuant to this Article V. 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.

     SECTION 5.11. Undertaking for Costs. In any suit for the enforcement of any right or remedy
under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a
trustee, a court in its discretion may require the filing by any party litigant in the suit of an
undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defenses made by the party litigant. This
Section 5.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 5.07,
or a suit by a Holder or Holders of more than 10% in aggregate principal amount of the Securities
then outstanding.

ARTICLE VI

TRUSTEE

     SECTION 6.01. Duties of Trustee.

          (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of
the rights and powers vested in it by this Indenture, and use the same degree of care and skill in
such exercise, as a prudent 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 need perform only those duties that are specifically set forth
in this Indenture and no others, and no implied covenants or obligations shall be
read into this Indenture against the Trustee; and

     (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. However, the Trustee shall

44

 

examine such certificates and opinions to determine whether or not, on their
face, they appear to conform to the requirements of this 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:

     (i) this paragraph does not limit the effect of paragraph (b) of this Section
6.01;

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

     (iii) the Trustee shall not be liable with respect to any action it takes or
omits to take in good faith in accordance with a direction received by it pursuant
to Section 5.05.

          (d) Whether or not therein expressly so provided, every provision of this Indenture that in
any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section 6.01.

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

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

     SECTION 6.02. Rights of Trustee.

          (a) The Trustee may rely conclusively on any resolution, certificate, statement, direction,
consent, order, bond, note or other paper or document believed by it to be genuine and to have been
signed or presented by the proper Person. The Trustee need not investigate any fact or matter
stated in any such paper or document.

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

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

45

 

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

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

          (f) The Trustee is not required to give any bond or surety with respect to the performance of
its duties or the exercise of its powers under this Indenture.

          (g) In the event the Trustee receives inconsistent or conflicting requests and indemnity from
two or more groups of Holders of Securities, each representing less than a majority in aggregate
principal amount of the outstanding Securities, pursuant to the provisions of this Indenture, the
Trustee may determine what action, if any, shall be taken.

          (h) The Trustee’s immunities and protections from liability and its right to indemnification
in connection with the performance of its duties under this Indenture shall extend and be
enforceable by the Trustee in each of its capacities hereunder and shall extend to the Trustee’s
officers, directors, agents, attorneys and employees. Such immunities and protections and right to
indemnity, together with the Trustee’s right to compensation, shall survive the Trustee’s
resignation or removal, the discharge of this Indenture and final payment of the Securities.

          (i) The permissive right of the Trustee to take the actions permitted by this Indenture shall
not be construed as an obligation or duty to do so.

          (j) Except for information provided by the Trustee concerning the Trustee, the Trustee shall
have no responsibility for any information in the Offering Memorandum or other disclosure material
distributed with respect to the Securities, and the Trustee shall have no responsibility for
compliance with any U.S. Federal or State securities or employee benefit plan laws in connection
with the Securities.

          (k) The Trustee may request that the Company or the Guarantor, as the case may be, deliver an
Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized
at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may
be signed by any person authorized to sign an Officers’ Certificate, including any person specified
as so authorized in any such certificate previously delivered and not superseded.

     SECTION 6.03. 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, the
Guarantor or any of their Affiliates with the same rights it would have if it were not the Trustee.
Any Agent may do the same with like rights. However, the Trustee is subject to Sections 6.10 and
6.11.

     SECTION 6.04. Trustee’s Disclaimer. The Trustee makes no representation as to the validity or
adequacy of this Indenture, the Securities or the Guarantees, it shall not be

46

 

accountable for the Company’s use of the proceeds from the Securities or any money paid to the
Company or upon the Company’s direction under any provision hereof, it shall not be responsible for
the use or application of any money received by any Paying Agent other than the Trustee and it
shall not be responsible for any statement or recital herein or any statement in the Securities
other than its certificate of authentication.

     SECTION 6.05. Notice of Defaults. If a Default or Event of Default occurs and is continuing
and it is actually known to a Responsible Officer of the Trustee, the Trustee shall mail to Holders
a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a
Default or Event of Default in payment of principal of or premium, if any, Additional Amounts, if
any, or interest on any Security, the Trustee may withhold the notice if and so long as a committee
of its Responsible Officers in good faith determines that withholding the notice is in the
interests of Holders.

     SECTION 6.06. Reports by Trustee to Holders. Within 60 days after May 15 of each year,
beginning with May 15, 2008, the Trustee shall mail to Holders a brief report dated as of May 15 of
such year that complies with TIA Section 313(a); provided, however, that if no event described in
TIA Section 313(a) has occurred within the 12 months preceding the reporting date, no report need
be transmitted. The Trustee also shall comply with TIA Section 313(b). The Trustee shall also
transmit by mail all reports as required by TIA Sections 313(c) and 313(d).

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

     SECTION 6.07. Compensation and Indemnity. The Company and the Guarantor jointly and severally
agree to pay to the Trustee from time to time such compensation as agreed to by the Company, the
Guarantor and the Trustee, for its acceptance of this Indenture and its services hereunder. The
Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express
trust. The Company and the Guarantor jointly and severally agree to reimburse the Trustee upon
request for all reasonable disbursements, advances and expenses incurred by it. Such expenses shall
include the reasonable compensation, disbursements and expenses of the Trustee’s agents and
counsel.

     The Company and the Guarantor jointly and severally agree to indemnify the Trustee or any
predecessor Trustee and their agents, employees, stockholders, officers and directors for and to
hold them harmless against any and all loss, liability, damage, claim, or expense (including
reasonable fees and expenses of counsel and taxes, other than taxes based upon, measured by or
determined by the income of the Trustee) incurred by it arising out of or in connection with this
Indenture or the administration of this trust, including the costs and expenses of enforcing this
Indenture against the Company and of defending itself against any claim (whether asserted by the
Company, the Guarantor, any Holder or any other Person), except as set forth in the next paragraph.
The Trustee shall notify the Company and the Guarantor promptly of any claim for which it may seek
indemnity; however, failure to give such notice shall not relieve the Company or the Guarantor of
their obligations. The Company shall defend the claim and the Trustee shall cooperate in the
defense. The Trustee may have separate counsel, and the Company and the Guarantor shall pay the
reasonable fees and expenses of such counsel. The Company need not

47

 

pay for any settlement made without its consent, which consent shall not be unreasonably
withheld.

     Neither the Company nor the Guarantor shall be obligated to reimburse any expense or indemnify
against any loss or liability incurred by the Trustee through negligence or bad faith.

     To secure the payment obligations of the Company and the Guarantor in this Section 6.07, the
Trustee shall have a lien prior to the Securities on all money or property held or collected by the
Trustee, except that held in trust to pay principal of and premium, if any, and Additional Amounts,
if any, and interest on the Securities. Such lien shall survive the satisfaction and discharge of
this Indenture.

     When the Trustee incurs expenses or renders services after an Event of Default specified in
Section 5.01(iv) or (v) occurs, the expenses and the compensation for the services are intended to
constitute expenses of administration under any Bankruptcy Law.

     SECTION 6.08. Replacement of Trustee. A resignation or removal of the Trustee and appointment
of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of
appointment as provided in this Section 6.08.

     The Trustee may resign and be discharged from the trust hereby created by so notifying the
Company and the Guarantor. The Holders of a majority in aggregate principal amount of the then
outstanding Securities may remove the Trustee by so notifying the Trustee and the Company. The
Company may remove the Trustee if:

          (i) the Trustee fails to comply with Section 6.10;

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

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

          (iv) the Trustee otherwise becomes incapable of acting.

     If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any
reason, the Company and the Guarantor shall promptly appoint a successor Trustee. Within one year
after the successor Trustee takes office, the Holders of a majority in principal amount of the
Securities then outstanding may appoint a successor Trustee to replace the successor Trustee
appointed by the Company.

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

48

 

     If the Trustee fails to comply with Section 6.10, any Holder may petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

     A successor Trustee shall deliver a written acceptance of its appointment to the retiring
Trustee and to the Company and the Guarantor. 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 Indenture. The successor Trustee shall mail a notice of its
succession to Holders. The retiring Trustee shall promptly transfer all property held by it as
Trustee to the successor Trustee, subject to the lien provided for in Section 6.07.
Notwithstanding replacement of the Trustee pursuant to this Section 6.08, the obligations of the
Company and the Guarantor under Section 6.07 shall continue for the benefit of the retiring
Trustee.

     SECTION 6.09. Successor Trustee by Merger, etc. Subject to Section 6.10, if the Trustee
consolidates, merges or converts into, or transfers all or substantially all of its corporate trust
business to, another corporation, the successor corporation without any further act shall be the
successor Trustee; provided, however, that in the case of a transfer of all or substantially all of
its corporate trust business to another corporation, the transferee corporation expressly assumes
all of the Trustee’s liabilities hereunder.

     In case any Securities shall have been authenticated, but not delivered, by the Trustee then
in office, any successor by merger, conversion or consolidation to such authenticating Trustee may
adopt such authentication and deliver the Securities so authenticated; and in case at that time any
of the Securities shall not have been authenticated, any successor to the Trustee may authenticate
such Securities either in the name of any predecessor hereunder or in the name of the successor to
the Trustee; and in all such cases such certificates shall have the full force which it is anywhere
in the Securities or in this Indenture provided that the certificate of the Trustee shall have.

     SECTION 6.10. Eligibility; Disqualification. 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 and authorized under such laws to exercise
corporate trust power, shall be subject to supervision or examination by Federal or State (or the
District of Columbia) authority and shall have, or be a Subsidiary of a bank or bank holding
company having, a combined capital and surplus of at least $50 million as set forth in its most
recent published annual report of condition.

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

     SECTION 6.11. Preferential Collection of Claims Against Company. The Trustee is subject to
and shall comply with the provisions of TIA Section 311(a), excluding any creditor relationship
listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA
Section 311(a) to the extent indicated therein.

ARTICLE VII

DISCHARGE OF INDENTURE

     SECTION 7.01. Termination of Company’s and Guarantor’s Obligations.

          (a) Satisfaction and Discharge of Indenture. This Indenture shall cease to be of further
effect (except as provided in the last paragraph of this Section 7.01(a)), and the Trustee, on
demand of the Company, shall execute proper instruments acknowledging the satisfaction and
discharge of this Indenture, when:

          (1) either

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

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

          (i) have become due and payable,

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

          (iii) will be scheduled for redemption by their terms within one year, and the
Company, in the case of clause (i) or (ii) above or this clause (iii), has deposited
or caused to be deposited with the Trustee as funds (immediately available to the
Holders in the case of clause (i)) in trust for such purpose an amount of cash or,
in the case of clause (ii) or this clause (iii), U.S. Government Obligations or a
combination thereof which, together with earnings thereon, will be sufficient, in
the case of clause (ii) or this clause (iii), in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, to pay and discharge the entire
indebtedness on such Securities for principal, premium, if any, Additional Amounts,
if any, and interest to the date of such deposit (in the case of Securities which
have become due and payable) or to the Stated Maturity or Redemption Date, as the
case may be;

          (2) the Company has paid all other sums payable by it hereunder; and

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

     However, the Company’s obligations in Sections 2.03, 2.06, 2.07, 3.02 and 7.01, the Company’s
and the Guarantor’s obligations in Sections 6.07, 6.08 and 7.04 and the Trustee’s and Paying
Agent’s obligations in Section 7.03 shall survive the satisfaction and discharge of this Indenture
until the Securities are no longer outstanding. Thereafter, only the Company’s and the

50

 

Guarantor’s obligations in Section 6.07 and the Trustee’s and Paying Agent’s obligations in
Section 7.03 shall survive.

          (b) Legal Defeasance. The Company and the Guarantor may, subject as provided herein,
terminate by legal defeasance all of their obligations under this Indenture if:

     (i) the Company has irrevocably deposited or caused to be irrevocably deposited
with the Trustee as trust funds in trust for the purpose of making the following
payments dedicated solely to the benefit of the Holders (A) cash in an amount, or
(B) U.S. Government Obligations, or (C) a combination thereof, sufficient, in the
opinion of a nationally recognized firm of independent public accountants expressed
in a written certification thereof delivered to the Trustee, to pay, without
consideration of the reinvestment of any such amounts and after payment of all taxes
or other charges or assessments in respect thereof payable by the Trustee, the
principal of and premium, if any, Additional Amounts, if any and interest on all
Securities on each date that such principal, premium, if any, Additional Amounts, if
any, or interest is due and payable and to pay all other sums payable by it
hereunder; provided that the Trustee shall have been irrevocably instructed to apply
such money or the proceeds of such U.S. Government Obligations to the payment of
said principal, premium, if any, Additional Amounts, if any, and interest with
respect to the Securities as the same shall become due;

     (ii) the Company has delivered to the Trustee an Officers’ Certificate stating
that all conditions precedent to such legal defesance have been complied with, and
an Opinion of Counsel to the same effect;

     (iii) no Default or Event of Default shall have occurred and be continuing on
the date of such deposit or, insofar as clauses (iv) and (v) of Section 5.01 are
concerned, at any time during the period ending on the 91st day after the date of
such deposit (it being understood that this condition shall not be deemed satisfied
until the expiration of such period);

     (iv) the Company shall have delivered to the Trustee an Opinion of Counsel from
nationally recognized counsel acceptable to the Trustee to the effect that, based on
a ruling of the Internal Revenue Service or a change in U.S. Federal income tax law
occurring after the date of this Indenture, the Holders of Securities will not
recognize income, gain or loss for U.S. Federal income tax purposes as a result of
the Company’s exercise of its option under this Section 7.01(b) and will be subject
to U.S. Federal income tax on the same amounts, in the same manner and at the same
times as would have been the case if such option had not been exercised;

     (v) such deposit and legal defeasance will not result in a breach or violation
of, or constitute a default under, any other agreement or instrument to which the
Company or the Guarantor is a party or by which it is bound;

51

 

     (vi) such deposit and legal defeasance shall not cause the Trustee to have a
conflicting interest as defined in TIA Section 310(b); and

     (vii) the Company shall have delivered to the Trustee an Opinion of Counsel to
the effect that after the passage of 91 days following the deposit, the trust funds
will not be subject to the effect of any applicable bankruptcy, insolvency,
reorganization or similar laws affecting creditors’ rights generally.

     In such event, payment of the Securities may not be accelerated because of an Event of
Default, Article IX and the other provisions of this Indenture shall cease to be of further effect
(except as provided in the next succeeding paragraph), and the Trustee, on demand of the Company,
shall execute proper instruments acknowledging such legal defeasance.

     However, the Company’s obligations in Sections 2.03, 2.06, 2.07, 3.02 and 7.01, the Company’s
and the Guarantor’s obligations in Sections 6.07, 6.08 and 7.04 and the Trustee’s and Paying
Agent’s obligations in Section 7.03 shall survive such legal defeasance until the Securities are no
longer outstanding. Thereafter, only the Company’s and the Guarantor’s obligations in Section 6.07
and the Trustee’s and Paying Agent’s obligations in Section 7.03 shall survive.

          (c) Covenant Defeasance. The Company and the Guarantor may, subject as provided herein, be
released from their respective obligations to comply with, and shall have no liability in respect
of any term, condition or limitation, set forth in Sections 3.07, 3.08, 3.09 and 4.01 and in
Article IX, and such omission to comply with any of Sections 3.07, 3.08, 3.09 and 4.01 and Article
IX shall not constitute an Event of Default under Section 5.01 (“Covenant Defeasance”), with the
remainder of this Indenture and such Securities unaffected thereby if:

     (i) the Company has irrevocably deposited or caused to be irrevocably deposited
with the Trustee as trust funds in trust for the purpose of making the following
payments dedicated solely to the benefit of the Holders (A) cash in an amount, or
(B) U.S. Government Obligations, or (C) a combination thereof, sufficient, in the
opinion of a nationally recognized firm of independent public accountants expressed
in a written certification thereof delivered to the Trustee, to pay, without
consideration of the reinvestment of any such amounts and after payment of all taxes
or other charges or assessments in respect thereof payable by the Trustee, the
principal of and premium, if any, Additional Amounts, if any and interest on all
Securities on each date that such principal, premium, if any, Additional Amounts, if
any, or interest is due and payable and to pay all other sums payable by it
hereunder; provided that the Trustee shall have been irrevocably instructed to apply
such money and/or the proceeds of such U.S. Government Obligations to the payment of
said principal, premium, if any, Additional Amounts, if any, and interest with
respect to the Securities as the same shall become due;

     (ii) the Company has delivered to the Trustee an Officers’ Certificate stating
that all conditions precedent to the Covenant Defeasance contemplated by

52

 

this provision have been complied with, and an Opinion of Counsel to the same
effect;

     (iii) no Default or Event of Default shall have occurred and be continuing on
the date of such deposit or, insofar as clauses (iv) and (v) of Section 5.01 are
concerned, at any time during the period ending on the 91st day after the date of
such deposit (it being understood that this condition shall not be deemed satisfied
until the expiration of such period);

     (iv) the Company shall have delivered to the Trustee an Opinion of Counsel from
nationally recognized counsel acceptable to the Trustee to the effect that the
Holders of Securities will not recognize income, gain or loss for U.S. Federal
income tax purposes as a result of the Company’s exercise of its option under this
Section 7.01(c) and will be subject to U.S. Federal income tax on the same amounts,
in the same manner and at the same times as would have been the case if such option
had not been exercised;

     (v) such Covenant Defeasance will not result in a breach or violation of, or
constitute a default under, any other agreement or instrument to which the Company
or the Guarantor is a party or by which it is bound;

     (vi) such Covenant Defeasance shall not cause the Trustee to have a conflicting
interest as defined in TIA Section 310(b); and

     (vii) the Company shall have delivered to the Trustee an Opinion of Counsel to
the effect that after the passage of 91 days following the deposit, the trust funds
will not be subject to the effect of any applicable bankruptcy, insolvency,
reorganization or similar laws affecting creditors’ rights generally.

          (d) In order to have money available on a payment date to pay principal of or premium, if any,
Additional Amounts, if any, or interest on the Securities, the U.S. Government Obligations shall be
payable as to principal or interest on or before such payment date in such amounts as will provide
the necessary money. U.S. Government Obligations shall not be callable at the issuer’s option.

          (e) The Company may exercise its option under Section 7.01(b) notwithstanding its prior
exercise of its Covenant Defeasance option under Section 7.01(c).

     SECTION 7.02. Application of Trust Money. The Trustee or a trustee satisfactory to the
Trustee and the Company shall hold in trust money or U.S. Government Obligations deposited with it
pursuant to Section 7.01. It shall apply the deposited money and the money from U.S. Government
Obligations through the Paying Agent and in accordance with this Indenture to the payment of
principal of and premium, if any, Additional Amounts, if any, and interest on Securities with
respect to which the deposit was made.

     SECTION 7.03. Repayment to Company. The Trustee and the Paying Agent shall promptly pay to
the Company upon written request any excess money or securities held by them at any time. Subject
to the requirements of any applicable abandoned property laws, the Trustee

53

 

and the Paying Agent shall pay to the Company upon written request any money held by them for
the payment of principal of, premium, if any, Additional Amounts, if any, or interest that remains
unclaimed for two years after the date upon which such payment shall have become due; provided,
however, that the Company shall have either caused notice of such payment to be mailed to each
Holder entitled thereto no less than 30 days prior to such repayment or within such period shall
have published such notice in a financial newspaper of widespread circulation published in The City
of New York. After payment to the Company, Holders entitled to the money must look to the Company
for payment as unsecured general creditors unless an applicable abandoned property law designates
another Person, and all liability of the Trustee and the Paying Agent with respect to such money
shall cease.

     SECTION 7.04. Reinstatement. If the Trustee or the Paying Agent is unable to apply any money
or U.S. Government Obligations in accordance with Section 7.01 by reason of any legal proceeding or
by reason of any order or judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the obligations of the Company and the Guarantor under this
Indenture and the Securities shall be revived and reinstated as though no deposit had occurred
pursuant to Section 7.01 until such time as the Trustee or the Paying Agent is permitted to apply
all such money or U.S. Government Obligations in accordance with Section 7.01; provided, however,
that if the Company or the Guarantor has made any payment of principal of or interest on any
Securities because of the reinstatement of its obligations, the Company or the Guarantor, as the
case may be, shall be subrogated to the rights of the Holders of such Securities to receive such
payment from the money or U.S. Government Obligations held by the Trustee or the Paying Agent.

ARTICLE VIII

AMENDMENTS

     SECTION 8.01. Without Consent of Holders. The Company, the Guarantor and the Trustee may
amend or supplement this Indenture or any of the Securities or waive any provision hereof or
thereof without the consent of any Holder:

     (i) to convey, transfer, assign, mortgage or pledge to the Trustee as security
for the Securities any property or assets;

     (ii) to evidence the succession of another Person to the Company or the
Guarantor, or successive successions, and the assumption by the successor Person of
the covenants, agreements and obligations of the Company or the Guarantor pursuant
to Section 4.01 or 4.02;

     (iii) to add to the covenants of the Company or the Guarantor such further
covenants, restrictions, conditions or provisions as the Company or the Guarantor
and the Trustee shall consider to be for the protection of the Holders of
Securities, to surrender any right or power herein conferred upon the Company or the
Guarantor, and to make the occurrence, or the occurrence and continuance, of a
default in any such additional covenants, restrictions, conditions or provisions an
Event of Default permitting the enforcement of all or any of the several remedies
provided in this Indenture, provided that in respect of any such

54

 

additional covenant, restriction, condition or provision such amendment or
supplement may provide for a particular period of grace after default (which period
may be shorter or longer than that allowed in the case of other defaults) or may
provide for an immediate enforcement upon such an Event of Default or may limit the
remedies available to the Trustee upon such an Event of Default or may limit the
right of the Holders of a majority in aggregate principal amount of the Securities
to waive such an Event of Default;

     (iv) to cure any ambiguity or omission or to correct or supplement any
provision contained herein or in any supplemental indenture which may be defective
or inconsistent with any other provision contained herein or in any supplemental
indenture, provided that no such action shall adversely affect the interests of the
Holders of the Securities;

     (v) to provide for uncertificated Securities in addition to or in place of
certificated Securities, provided that the uncertificated Securities are issued in
registered form for purposes of Section 163(f) of the Code, or in a manner such that
uncertificated notes are described in Section 163(f)(2)(B) of the Code;

     (vi) to provide for the issuance of Exchange Securities and related Guarantees
or Additional Securities and related Guarantees in accordance with this Indenture;

     (vii) to effect or maintain, or otherwise comply with the requirements of the
SEC in connection with, the qualification of this Indenture under the TIA;

     (viii) to effect any provision of this Indenture; or

     (ix) to make any other change that does not adversely affect the rights of any
Holder.

     Upon the request of the Company and the Guarantor accompanied by a resolution of the Board of
Directors of each of the Company and the Guarantor authorizing the execution of any supplemental
indenture entered into to effect any such amendment, supplement or waiver, and upon receipt by the
Trustee of the documents described in Section 8.06, the Trustee shall join with the Company and the
Guarantor in the execution of such supplemental indenture. After an amendment, supplement or
waiver under this Section 8.01 becomes effective, the Company shall mail to the Holders of each
Security affected thereby a notice briefly describing the amendment, supplement or waiver. Any
failure of the Company to mail such notice, or any defect therein, shall not, however, in any way
impair or affect the validity of any such amendment, supplement or waiver.

     SECTION 8.02. With Consent of Holders. Except as provided below in this Section 8.02, the
Company, the Guarantor and the Trustee may amend or supplement this Indenture with the consent
(including consents obtained in connection with a tender offer or exchange offer for the Securities
or a solicitation of consents in respect of the Securities, provided that in each case such offer
or solicitation is made to all Holders of the Securities then outstanding on equal terms)

55

 

of the Holders of at least a majority in aggregate principal amount of the Securities then
outstanding affected thereby.

     The Holders of a majority in aggregate principal amount of the Securities then outstanding may
waive compliance in a particular instance by the Company or the Guarantor with any provision of
this Indenture or the Securities (including waivers obtained in connection with a tender offer or
exchange offer for the Securities or a solicitation of consents in respect of the Securities,
provided that in each case such offer or solicitation is made to all Holders of the Securities then
outstanding on equal terms).

     Upon the request of the Company and the Guarantor accompanied by a resolution of the Board of
Directors of each of the Company and the Guarantor authorizing the execution of any supplemental
indenture entered into to effect any such amendment, supplement or waiver, and upon the filing with
the Trustee of evidence of the consent of the Holders as aforesaid, and upon receipt by the Trustee
of the documents described in Section 8.06, the Trustee shall join with the Company and the
Guarantor in the execution of such supplemental indenture. After an amendment, supplement or waiver
under this Section 8.02 becomes effective, the Company shall mail to the Holders of each Security
affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in any way impair or
affect the validity of any such amendment, supplement or waiver.

     It shall not be necessary for the consent of the Holders under this Section 8.02 to approve
the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if
such consent approves the substance thereof.

     Without the consent of each Holder affected, an amendment, supplement or waiver under this
Section 8.02 may not:

     (i) extend the final maturity of the principal of any of the Securities;

     (ii) reduce the principal amount of any of the Securities;

     (iii) reduce the rate or extend the time of payment of interest, including
default interest, or Additional Amounts, if any, on any of the Securities;

     (iv) reduce any amount payable on redemption of any of the Securities;

     (v) change the currency in which the principal of or premium, if any,
Additional Amounts, if any, or interest on any of the Securities is payable;

     (vi) impair the right to institute suit for the enforcement of any payment of
principal of or premium, if any, Additional Amounts, if any, or interest on any
Security pursuant to Sections 5.07 and 5.08, except as limited by Section 5.06;

     (vii) make any change in the percentage of principal amount of the Securities
necessary to waive compliance with or to modify certain provisions of

56

 

          this Indenture pursuant to Section 5.04 or 5.07 or this clause of this Section 8.02; or

               (viii) waive a continuing Default or Event of Default in the payment of
principal of or premium, if any, Additional Amounts, if any, or interest, including
default interest, on the Securities.

     The right of any Holder to participate in any consent required or sought pursuant to any
provision of this Indenture (and the obligation of the Company to obtain any such consent otherwise
required from such Holder) may be subject to the requirement that such Holder shall have been the
Holder of record of the Securities as of a record date fixed by the Company in accordance with
Section 8.04 of this Indenture.

     SECTION 8.03. Compliance with Trust Indenture Act. Every amendment or supplement to this
Indenture or the Securities shall comply in form and substance with the TIA as then in effect.

     SECTION 8.04. Revocation and Effect of Consents. A consent to an amendment, a supplement or a
waiver by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security
or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if
notation of the consent is not made on any Security. However, any such Holder or subsequent Holder
may revoke the consent as to its Security or portion of a Security if the Trustee receives written
notice of revocation at any time prior to (but not after) the date the Trustee receives an
Officers’ Certificate certifying that the Holders of the requisite principal amount of Securities
have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver.
An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter
binds every Holder, and a consent thereto given in connection with a tender of a Holder’s
Securities shall not be rendered invalid by such tender.

     The Company may, but shall not be obligated to, fix a record date for the purpose of
determining the Holders entitled to consent to any amendment, supplement or waiver or to take any
other action with respect to the Securities under this Indenture. If a record date is fixed, then
notwithstanding the provisions of 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 consent to such amendment, supplement or waiver or to revoke
any consent previously given, 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 consent shall be valid or effective for more than 90 days after such record date unless
consents from Holders of the principal amount of the Securities required hereunder for such
amendment, supplement or waiver to be effective shall have also been given and not revoked within
such 90-day period.

     After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless
it is of the type described in any of clauses (i) through (viii) of Section 8.02. In such case, the
amendment, supplement or waiver shall bind each Holder who has consented to it and every subsequent
Holder that evidences the same debt as the consenting Holder’s Security.

57

 

     SECTION 8.05. 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. Failure to make the appropriate notation or to issue a new
Security shall not affect the validity of such amendment or supplement.

     SECTION 8.06. Trustee to Sign Amendments, etc. The Trustee shall sign any supplemental
indenture authorized pursuant to this Article VIII if the supplemental indenture does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may,
but need not, sign it. In signing or refusing to sign such supplemental indenture, the Trustee
shall receive, and subject to Section 6.01, shall be fully protected in relying upon, an Opinion of
Counsel and an Officers’ Certificate, as conclusive evidence that all conditions precedent to such
supplemental indenture have been complied with, that such supplemental indenture is authorized or
permitted by this Indenture, that it is not inconsistent herewith, and that it will be valid and
binding upon the Company and the Guarantor in accordance with its terms.

ARTICLE IX

GUARANTEES OF SECURITIES

     SECTION 9.01. Unconditional Guarantees.

          (a) For value received, the Guarantor hereby fully, irrevocably, unconditionally and
absolutely guarantees to the Holders and to the Trustee the due and punctual payment of the
principal of and premium, if any, Additional Amounts, if any, and interest on the Securities and
all other amounts due and payable under this Indenture and the Securities by the Company
(including, without limitation, all costs and expenses (including reasonable legal fees and
disbursements) incurred by the Trustee or the Holders in connection with the enforcement of this
Indenture, the Securities and the Guarantees) (collectively, the “Indenture Obligations”), when and
as such principal, premium, if any, Additional Amounts, if any, and interest and such other amounts
shall become due and payable, whether at the Stated Maturity, upon redemption or by declaration of
acceleration or otherwise, according to the terms of the Securities and this Indenture. The
guarantees by the Guarantor set forth in this Article IX are referred to herein as the
“Guarantees.” Without limiting the generality of the foregoing, the Guarantor’s liability shall
extend to all amounts that constitute part of the Indenture Obligations and would be owed by the
Company under this Indenture and the Securities but for the fact that they are unenforceable,
reduced, limited, impaired, suspended or not allowable due to the existence of a bankruptcy,
reorganization or similar proceeding involving the Company.

          (b) Failing payment when due of any amount guaranteed pursuant to the Guarantees, for whatever
reason, the Guarantor will be obligated to pay the same immediately to the Trustee, without set-off
or counterclaim or other reduction whatsoever (whether for taxes, withholding or otherwise). The
Guarantees are intended to be general, unsecured, senior obligations of the Guarantor and to rank
pari passu in right of payment with all indebtedness of

58

 

the Guarantor that is not, by its terms, expressly subordinated in right of payment to the
Guarantees of the Guarantor. The Guarantor hereby agrees that its obligations hereunder shall be
full, irrevocable, unconditional and absolute, irrespective of the validity, regularity or
enforceability of the obligations and liabilities of any other obligor with respect to the
Securities, the Guarantees or this Indenture, the absence of any action to enforce the same, any
waiver or consent by any Holder with respect to any provisions hereof or thereof with respect to
the same, the recovery of any judgment against the Company, or any other circumstance which might
otherwise constitute a legal or equitable discharge or defense of the Guarantor.

     The Guarantor hereby agrees that in the event of a default in payment of the principal of or
premium, if any, Additional Amounts, if any, or interest on the Securities or any other amounts
payable under this Indenture and the Securities by the Company, whether at the Stated Maturity,
upon redemption or by declaration of acceleration or otherwise, legal proceedings may be instituted
by the Trustee on behalf of the Holders or, subject to Section 5.06, by the Holders, on the terms
and conditions set forth in this Indenture, directly against the Guarantor to enforce the
Guarantees without first proceeding against the Company.

          (c) To the fullest extent permitted by applicable law, the obligations of the Guarantor under
this Article IX shall be as aforesaid full, irrevocable, unconditional and absolute and shall not
be impaired, modified, discharged, released or limited by any occurrence or condition whatsoever,
including, without limitation, (i) any compromise, settlement, release, waiver, renewal, extension,
indulgence or modification of, or any change in, any of the obligations and liabilities of any
other obligor with respect to the Securities contained in any of the Securities or this Indenture,
(ii) any impairment, modification, release or limitation of the liability of the Company, the
Guarantor or any of their respective estates in bankruptcy, or any remedy for the enforcement
thereof, resulting from the operation of any present or future provision of any applicable
Bankruptcy Law, or other statute or from the decision of any court, (iii) the assertion or exercise
by the Company, the Guarantor or the Trustee of any rights or remedies under any of the Securities
or this Indenture or its delay in or failure to assert or exercise any such rights or remedies,
(iv) the assignment or the purported assignment of any property as security for any of the
Securities, including all or any part of the rights of the Company or the Guarantor under this
Indenture, (v) the extension of the time for payment by the Company or the Guarantor of any
payments or other sums or any part thereof owing or payable under any of the terms and provisions
of any of the Securities or this Indenture or of the time for performance by the Company or the
Guarantor of any other obligations under or arising out of any such terms and provisions or the
extension or the renewal of any thereof, (vi) the modification or amendment (whether material or
otherwise) of any duty, agreement or obligation set forth in this Indenture of any other obligor
with respect to the Securities, (vii) the voluntary or involuntary liquidation, dissolution, sale
or other disposition of all or substantially all of the assets, marshaling of assets and
liabilities, receivership, insolvency, bankruptcy, assignment for the benefit of creditors,
reorganization, arrangement, composition or readjustment of, or other similar proceeding affecting,
either of the Company or the Guarantor or any of its assets, or the disaffirmance of any of the
Securities, the Guarantees or this Indenture in any such proceeding, (viii) the release or
discharge of the Company or the Guarantor from the performance or observance of any agreement,
covenant, term or condition contained in any of such instruments by operation of law, (ix) the
unenforceability of any of the obligations of any of the other obligors under the Securities, the
Guarantees or this Indenture, (x) any change in the name,

59

 

business, capital structure, corporate existence, or ownership of the Company or the
Guarantor, or (xi) any other circumstance which might otherwise constitute a defense available to,
or a legal or equitable discharge of, a surety or the Guarantor.

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

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

          (f) No failure to exercise and no delay in exercising, on the part of the Trustee or the
Holders, any right, power, privilege or remedy under this Article IX and the Guarantees shall
operate as a waiver thereof, nor shall any single or partial exercise of any rights, power,
privilege or remedy preclude any other or further exercise thereof, or the exercise of any other
rights, powers, privileges or remedies. The rights and remedies herein provided for are cumulative
and not exclusive of any rights or remedies provided in law or equity. Nothing contained in this
Article IX shall limit the right of the Trustee or the Holders to take any action to accelerate the
Maturity of the Securities pursuant to Article V or to pursue any rights or remedies hereunder or
under applicable law.

     SECTION 9.02. Execution and Delivery of Notation of Guarantees. To further evidence the
Guarantees, the Guarantor hereby agrees that a notation of such Guarantees may be endorsed on each
Security authenticated and delivered by the Trustee and that such notation shall be executed by
either manual or facsimile signature of an Officer of the Guarantor.

     The Guarantor hereby agrees that its Guarantees shall remain in full force and effect
notwithstanding any failure to endorse on each Security a notation of the Guarantees.

     If an Officer of the Guarantor whose signature is on this Indenture or a Security no longer
holds that office at the time the Trustee authenticates such Security or at any time thereafter,
the Guarantor’s guarantee of such Security shall be valid nevertheless.

60

 

     The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall
constitute due delivery of the Guarantees set forth in this Indenture on behalf of the Guarantor.

ARTICLE X

REDEMPTION

     SECTION 10.01. Notices to Trustee. If the Company elects to redeem the Securities pursuant to
the redemption provisions of Section 10.07, it shall furnish to the Trustee, at least five days
before notice of such redemption is to be given pursuant to Section 10.03, an Officers’ Certificate
setting forth the Redemption Date, the principal amount of such Securities to be redeemed and the
Redemption Price (or the method of calculating the Redemption Price).

     SECTION 10.02. Selection of Securities to be Redeemed. If less than all of the Securities are
to be redeemed, the Trustee shall select the Securities to be redeemed by such method as the
Trustee in its sole discretion shall deem fair and appropriate. The particular Securities to be
redeemed shall be selected by the Trustee from the outstanding Securities not previously called for
redemption.

     The Trustee shall promptly notify the Company in writing of the Securities selected for
redemption and, in the case of any Security selected for partial redemption, the principal amount
thereof to be redeemed. Securities and portions of them selected shall be in minimum amounts of
$2,000 and integral multiples of $1,000 in excess thereof. Except as provided in the preceding
sentence, provisions of this Indenture that apply to Securities called for redemption also apply to
portions of Securities called for redemption.

     SECTION 10.03. Notices to Holders.

          (a) At least 20 days but not more than 75 days before a Redemption Date (unless a different
notice period is specified in the Securities), the Company shall mail in conformity with Section
11.02 a notice of redemption to each Holder whose Securities are to be redeemed. The notice shall
identify the Securities to be redeemed (including CUSIP, ISIN or similar numbers, if any) and shall
state:

               (i) the Redemption Date;

               (ii) the Redemption Price (or the method of calculating the Redemption Price);

               (iii) if any Security is being redeemed in part, the portion of the principal
amount of such Security to be redeemed and that, after the Redemption Date, upon
surrender of such Security, a new Security or Securities in principal amount equal
to the unredeemed portion will be issued;

               (iv) the name and address of the Paying Agent;

61

 

               (v) that Securities called for redemption must be surrendered to the Paying
Agent at the address specified in such notice to collect the Redemption Price;

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

               (vii) the aggregate principal amount of Securities being redeemed.

     If any of the Securities to be redeemed is in the form of a Global Security, then the Company
shall modify such notice to the extent necessary to accord with the procedures of the Depositary
applicable to redemptions.

          (b) At the Company’s request, the Trustee shall give the notice required in Section 10.03(a)
in the Company’s name; provided, however, that the Company shall deliver to the Trustee, at least
15 days prior to the requested mailing date (unless the Trustee consents in writing to a shorter
period), an Officers’ Certificate requesting that the Trustee give such notice and setting forth
the information to be stated in such notice as provided in Section 10.03(a).

     SECTION 10.04. Effect of Notices of Redemption. Once notice of redemption is mailed pursuant
to Section 10.03, Securities called for redemption become due and payable on the Redemption Date at
the Redemption Price. Upon surrender to the Paying Agent, such Securities shall be paid out at the
Redemption Price, plus accrued and unpaid interest up to, but not including, the Redemption Date;
provided, however, 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.

     SECTION 10.05. Deposit of Redemption Price. At or prior to 11:00 a.m. New York City time on
the Redemption Date, the Company shall deposit with the Trustee or with the Paying Agent
immediately available funds sufficient to pay the Redemption Price of all Securities to be redeemed
on that date, plus accrued and unpaid interest thereon up to, but not including, the Redemption
Date. The Trustee or the Paying Agent shall return to the Company any money not required for that
purpose less the expenses of the Trustee as provided herein.

     If the Company complies with the preceding paragraph, interest on the Securities or portions
thereof to be redeemed (whether or not such Securities are presented for payment) will cease to
accrue on the applicable Redemption Date. If any Security called for redemption shall not be so
paid upon surrender because of the failure of the Company to comply with the preceding paragraph,
then interest will be paid on the unpaid principal, premium, if any, and Additional Amounts, if
any, from the Redemption Date until such principal, premium, if any, and Additional Amounts, if
any, are paid and, to the extent lawful, on any interest not paid on such unpaid principal, in each
case at the rate provided in the Securities and in Section 3.01.

62

 

     SECTION 10.06. Securities Redeemed in Part. Upon surrender of a Security that is redeemed in
part, the Company shall issue and the Trustee shall authenticate for the Holder, at the expense of
the Company, a new Security equal in principal amount to the unredeemed portion of the Security
surrendered.

     SECTION 10.07. Optional Redemption. The Securities may be redeemed at any time on such terms
and subject to such conditions as are specified in such Securities.

     Any redemption pursuant to this Section 10.07 shall be made, to the extent applicable,
pursuant to the provisions of Sections 10.01 through 10.06.

     SECTION 11.08. No Recourse Against Others. A director, officer, employee or stockholder of

or the United States District Court for the Southern District of New York, in either case in the

hereafter have to the laying of venue of any such proceeding and expressly and irrevocably accepts
and submits, for the benefit of the Holders from time to time

65

 

of the Securities, to the nonexclusive jurisdiction of any such court in respect of any such
action, suit or proceeding, for itself and with respect to its properties, revenues and assets.
Such appointment shall be irrevocable unless and until the appointment of a successor authorized
agent for such purpose, and such successor’s acceptance of such appointment, shall have occurred.
The Guarantor agrees to take any and all actions, including the filing of any and all documents and
instruments, that may be necessary to continue such appointment in full force and effect as
aforesaid. Service of process upon the Authorized Agent with respect to any such action shall be
deemed, in every respect, effective service of process upon the Guarantor. Notwithstanding the
foregoing, any action against the Guarantor arising out of or based on any Security or the
Guarantees may also be instituted by the Holder of such Security in any court in the jurisdiction
of organization of the Guarantor, and the Guarantor expressly accepts the jurisdiction of any such
court in any such action. The Company hereby accepts the foregoing appointment as agent for
service of process.

     SECTION 11.11. Waiver of Immunity. To the extent that the Guarantor or any of its properties,
assets or revenues may have or may hereafter become entitled to, or have attributed to it, any
right of immunity, on the grounds of sovereignty or otherwise, from any legal action, suit or
proceeding, from the giving of any relief in any thereof, from set-off or counterclaim, from the
jurisdiction of any court, from service of process, from attachment upon or prior to judgment, from
attachment in aid of execution of judgment, or from execution of judgment, or other legal process
or proceeding for the giving of any relief or for the enforcement of any judgment, in any
jurisdiction in which proceedings may at any time be commenced, with respect to its obligations,
liabilities or any other matter under or arising out of or in connection with this Indenture or the
Securities, the Guarantor, to the maximum extent permitted by law, hereby irrevocably and
unconditionally waives, and agrees not to plead or claim, any such immunity and consents to such
relief and enforcement.

     SECTION 11.12. Judgment Currency. The Guarantor agrees to indemnify the Trustee and each
Holder against any loss incurred by it as a result of any judgment or order being given or made and
expressed and paid in a currency (the “Judgment Currency”) other than U.S. dollars and as a result
of any variation as between (a) the rate of exchange at which the U.S. dollar amount is converted
into the Judgment Currency for the purpose of such judgment or order and (b) the spot rate of
exchange in The City of New York at which the Trustee or such Holder on the date of payment of such
judgment or order is able to purchase U.S. dollars with the amount of the Judgment Currency
actually received by the Trustee or such Holder. The foregoing indemnity shall constitute a
separate and independent obligation of the Guarantor and shall continue in full force and effect
notwithstanding any such judgment or order as aforesaid. The term “spot rate of exchange” shall
include any premiums and costs of exchange payable in connection with the purchase of, or
conversion into, U.S. dollars.

     SECTION 11.13. No Adverse Interpretation of Other Agreements. This Indenture may not be used
to interpret another indenture, loan or debt agreement of the Company, the Guarantor or any other
Subsidiary of the Guarantor. Any such indenture, loan or debt agreement may not be used to
interpret this Indenture.

66

 

     SECTION 11.14. Successors. All agreements of the Company and the Guarantor in this Indenture
and the Securities shall bind their respective successors. All agreements of the Trustee in this
Indenture shall bind its successor.

     SECTION 11.15. Severability. In case any provision in this Indenture or in the Securities
shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the
remaining provisions shall not in any way be affected or impaired thereby.

     SECTION 11.16. Counterpart Originals. The parties may sign any number of copies of this
Indenture by manual or facsimile signature. Each signed copy shall be an original, but all of them
together represent the same agreement.

REVERSE OF SECURITY

NABORS INDUSTRIES, INC.

6.15% SENIOR NOTE DUE 2018

     This Security is one of a duly authorized issue of 6.15% Senior Notes due 2018 (the
“Securities”) of Nabors Industries, Inc., a Delaware corporation (the “Company”).

     1. Interest. The Company promises to pay interest on the principal amount of this Security at
6.15% per annum from February 20, 2008 until maturity. The Company will pay interest semiannually
on February 15 and August 15 of each year (each an “Interest Payment Date”), beginning August 15,
2008, or if any such day is not a Business Day, on the next succeeding Business Day. Interest on
this Security will accrue from the most recent Interest Payment Date on which interest has been
paid or, if no interest has been paid, from February 20, 2008; provided that if there is no
existing Default in the payment of interest, and if this Security is 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. Further, to the extent lawful, the Company
shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on
overdue principal, premium, if any, Additional Amounts, if any, and interest (without regard to any
applicable grace period), from time to time on demand at the rate then in effect on the Securities.
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 this Security (except defaulted
interest) to the Persons who are registered Holders of this Security at the close of business on
the record date next preceding the Interest Payment Date, even if this Security is canceled after
such record date and on or before such Interest Payment Date. The Holder must surrender this
Security to a Paying Agent to collect payments of principal and premium, if any. The Company will
pay the principal of and premium, if any, and Additional Amounts, if any, and interest on this
Security in money of the United States of America that at the time of payment is legal tender for
payment of public and private debts. Payments in respect of the Securities represented by a Global
Security (including principal, premium, if any, Additional Amounts, if any, and interest) will be
made by wire transfer of immediately available funds to the accounts specified by The Depository
Trust Company. The Company will make all payments in respect of a certificated Security (including
principal, premium, if any, Additional Amounts, if any, and interest) at the office or agency of
the Paying Agent maintained for such purpose in The City of New York or by mailing a check to the
registered address of each Holder thereof; provided, however, that payments on a certificated
Security will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank
in the United States if such Holder elects payment by wire transfer by giving written notice to the
Trustee or the Paying Agent to such effect designating such account no later than 30 days
immediately preceding the relevant due date for payment (or such other date as the Trustee may
accept in its discretion).

     3. Ranking and Guarantees. This Security is a senior unsecured obligation of the Company and
is guaranteed pursuant to guarantees (the “Guarantees”) by Nabors Industries Ltd., a Bermuda
exempted company (the “Guarantor”). The Guarantees are senior unsecured

Exhibit A-5

 

 

obligations of the Guarantor. References herein to the Indenture or the Securities shall be
deemed also to refer to the Guarantees set forth in the Indenture except where the context
otherwise requires.

     4. Optional Redemption; Purchases Upon Change of Control.

     (a) This Security is redeemable, in whole or in part, at any time, at the Company’s option, at
a Redemption Price equal to the greater of (1) 100% of the principal amount of this Security then
outstanding to be redeemed, or (2) the sum of the present values of the remaining scheduled
payments of principal and interest thereon (exclusive of interest accrued to the Redemption Date)
computed by discounting such payments to the Redemption Date on a semiannual basis (assuming a
360-day year consisting of twelve 30-day months) at a rate equal to the sum of 35 basis points plus
the Adjusted Treasury Rate on the third Business Day prior to the Redemption Date, as calculated by
an Independent Investment Banker, plus accrued and unpaid interest hereon up to, but not including,
the Redemption Date (subject to the right of the holder of record of this Security on the relevant
record date to receive interest on the relevant Interest Payment Date as provided in Section 10.04
of the Indenture).

     “Adjusted Treasury Rate” means, with respect to any Redemption Date, the yield, under the
heading which represents the average for the immediately preceding week, appearing in the most
recently published statistical release designated “H.15(519)” or any successor publication which is
published weekly by the Board of Governors of the Federal Reserve System and which establishes
yields on actively traded U.S. Treasury securities adjusted to constant maturity under the caption
“Treasury Constant Maturities” for the maturity corresponding to the Optional Redemption Comparable
Treasury Issue (if no maturity is within three months before or after the remaining term of this
Security, yields for the two published maturities most closely corresponding to the Optional
Redemption Comparable Treasury Issue will be determined and the Adjusted Treasury Rate will be
interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest
month); or if such release (or any successor release) is not published during the week preceding
the calculation date or does not contain such yields, the rate per annum equal to the semiannual
equivalent yield to maturity of the Optional Redemption Comparable Treasury Issue, calculated using
a price for the Optional Redemption Comparable Treasury Issue (expressed as a percentage of its
principal amount) equal to the Optional Redemption Comparable Treasury Price for such redemption
date.

     “Independent Investment Banker” means Citigroup Global Markets Inc., or if such firm is
unwilling or unable to serve as such, an independent investment and banking institution of national
standing appointed by the Trustee.

     “Optional Redemption Reference Treasury Dealer” means each of up to five dealers to be
selected by the Company and the Guarantor, and their respective successors; provided that if any of
the foregoing ceases to be, and has no affiliate that is, a primary U.S. governmental securities
dealer (a “Primary Treasury Dealer”), the Company and the Guarantor will substitute for it another
Primary Treasury Dealer.

     “Optional Redemption Comparable Treasury Issue” means the U.S. Treasury security selected by
an Independent Investment Banker as having a maturity comparable to the remaining

Exhibit A-6

 

 

term of the Securities to be redeemed that would be utilized, at the time of selection and in
accordance with customary financial practice, in pricing new issues of corporate debt securities of
comparable maturity to the remaining term of this Security, or, if, in the reasonable judgment of
the Independent Investment Banker, there is no such security, then the Optional Redemption
Comparable Treasury Issue will mean the U.S. Treasury security or securities selected by the
Independent Investment Banker as having an actual or interpolated maturity or maturities comparable
to the remaining term of this Security.

     “Optional Redemption Comparable Treasury Price” means (1) the average of five Optional
Redemption Reference Treasury Dealer Quotations for the applicable redemption date, after excluding
the highest and lowest Optional Redemption Reference Treasury Dealer Quotations, or (2) if the
Independent Investment Banker obtains fewer than five such Optional Redemption Reference Treasury
Dealer Quotations, the average of all such quotations.

     “Optional Redemption Reference Treasury Dealer Quotations” means, with respect to each
Optional Redemption Reference Treasury Dealer and any Redemption Date for this Security, the
average, as determined by the Independent Investment Banker of the bid and asked prices for the
Optional Redemption Comparable Treasury Issue (expressed in each case as a percentage of its
principal amount) quoted in writing to the Independent Investment Banker and the Trustee at 5:00
p.m., New York City time, on the third Business Day preceding such Redemption Date.

     (b) Upon the occurrence of a Change of Control Triggering Event, each Holder shall have the
right to require the Company to purchase all or any part (equal to $2,000 or an integral multiple
of $1,000 in excess thereof) of this Security, pursuant to a Change of Control Offer made in
accordance with Section 3.10 of the Indenture, at a purchase price in cash equal to 101% of the
principal amount hereof, plus accrued and unpaid interest hereon up to, but not including, the
Redemption Date (subject to the right of the holder of record of this Security on the relevant
record date to receive interest on the relevant Interest Payment Date as provided in Section 3.10
of the Indenture), except to the extent that the Company shall have exercised its right to redeem
this Security pursuant to the preceding paragraph (a).

     (c) 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, purchases all
of the Securities validly tendered and not withdrawn by such holders, the Company shall 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 such Change of Control Offer, to redeem this Security and all
other Securities that remain outstanding following such purchase at a Redemption Price in cash
equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, up to, but
not including, the Redemption Date (subject to the right of the holder of record of this Security
on the relevant record date to receive interest on the relevant Interest Payment Date as provided
in Section 10.04 of the Indenture).

     5. Paying Agent and Registrar. Initially, Wells Fargo Bank, National Association (the
“Trustee”), the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company
may change any Paying Agent, Registrar, co-registrar or additional paying agent

Exhibit A-7

 

 

without notice to any Holder. The Guarantor or any of its Subsidiaries may act in any such
capacity.

     6. Indenture. The Company issued this Security under an Indenture dated as of February 20,
2008 (as amended, supplemented or otherwise modified from time to time, the “Indenture”) among the
Company, the Guarantor and the Trustee. The terms of this Security include those stated in the
Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as
amended (15 U.S. Code Sections 77aaa-77bbbb). This Security and the Guarantees are subject to all
such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement
of such terms. To the extent any provision of this Security conflicts with the express provisions
of the Indenture, the provisions of the Indenture shall govern and be controlling (to the extent
permitted by law). The Securities are unsecured obligations of the Company. The Company initially
has issued $575,000,000 aggregate principal amount of Securities. The Company may issue Additional
Securities under the Indenture, provided 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. Capitalized terms used but not defined in this Security have the
respective meanings given to such terms in the Indenture.

     7. Denominations, Transfer, Exchange. The Securities are issuable only in registered form
without coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess
thereof. The transfer of this Security may be registered and this Security may be exchanged as
provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things,
to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required
by law or permitted by the Indenture. The Registrar need not exchange or register the transfer of
this Security during the period between a record date and the corresponding Interest Payment Date.

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

     9. Amendments and Waivers. Subject to certain exceptions and limitations, the Indenture or
this Security may be amended or supplemented with the consent of the Holders of at least a majority
in aggregate principal amount of the then outstanding Securities, and compliance in a particular
instance by the Company or the Guarantor with any provision of the Indenture with respect to the
Securities may be waived (other than certain provisions, including any continuing Default or Event
of Default in the payment of the principal of or premium, if any, Additional Amounts, if any, or
interest on the Securities) by the Holders of at least a majority in aggregate principal amount of
the Securities then outstanding in accordance with the terms of the Indenture. Without the consent
of any Holder, the Company, the Guarantor and the Trustee may amend or supplement the Indenture or
this Security to: (i) convey, transfer, assign, mortgage or pledge to the Trustee as security for
this Security any property or assets; (ii) to evidence the succession of another entity to the
Company or the Guarantor, or successive successions, and the assumption by the successor entity of
the covenants, agreements and obligations of the Company or the Guarantor pursuant to Section 4.01
or 4.02 of the Indenture; (iii) to add to the covenants of the Company or the Guarantor such
further covenants, restrictions, conditions or provisions as the Company or the Guarantor and the
Trustee shall consider to be for the protection of the

Exhibit A-8

 

 

Holders of Securities, to surrender any right or power conferred upon the Company or the
Guarantor, and to make the occurrence, or the occurrence and continuance, of a default in any such
additional covenants, restrictions, conditions or provisions an Event of Default permitting the
enforcement of all or any of the several remedies provided in the Indenture, provided that in
respect of any such additional covenant, restriction, condition or provision such amendment or
supplement may provide for a particular period of grace after default (which period may be shorter
or longer than that allowed in the case of other defaults) or may provide for an immediate
enforcement upon such an Event of Default or may limit the remedies available to the Trustee upon
such an Event of Default or may limit the right of the Holders of a majority in aggregate principal
amount of the Securities to waive such an Event of Default; (iv) to cure any ambiguity or omission
or to correct or supplement any provision contained in the Indenture or in any supplemental
indenture which may be defective or inconsistent with any other provision contained in the
Indenture or in any supplemental indenture, provided that no such action shall adversely affect the
interests of the Holders of this Security; (v) to provide for uncertificated Securities in addition
to or in place of certificated Securities, subject to any restrictions contained in the Indenture;
(vi) to provide for the issuance of Exchange Securities and related Guarantees or Additional
Securities and related Guarantees in accordance with the Indenture; (vii) to effect or maintain, or
otherwise comply with the requirements of the SEC in connection with, the qualification of the
Indenture under the TIA; (viii) to effect any provision of the Indenture; or (ix) to make any other
change that does not adversely affect the rights of any Holder

     The right of any Holder to participate in any consent required or sought pursuant to any
provision of the Indenture (and the obligation of the Company to obtain any such consent otherwise
required from such Holder) may be subject to the requirement that such Holder shall have been the
Holder of record of this Security as of a record date fixed by the Company in accordance with the
terms of the Indenture.

     10. Defaults and Remedies. Events of Default include: (i) default in the payment of the
principal of or premium, if any, on any Security at its Maturity, and continuance of such default
for a period of 10 days; or (ii) default in the payment of interest or Additional Amounts, if any,
upon any of the Securities when they become due and payable, and continuance of such default for a
period of 30 days; or (iii) default in the performance or observance, or breach, of any covenant of
the Company or the Guarantor in any Security or the Indenture (other than a covenant a default in
whose performance or whose breach is elsewhere in Section 5.01 of the Indenture specifically dealt
with), 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 and the Guarantor by the Trustee or to the
Company, the Guarantor and the Trustee by the Holders of at least 25% in aggregate principal amount
of the outstanding Securities a written notice specifying such default or breach and requiring it
to be remedied and stating that such notice is a “Notice of Default” under the Indenture; or (iv)
certain events specified in the Indenture relating to the bankruptcy, insolvency or reorganization
of the Company or the Guarantor; or (vi) the Guarantees cease to be in full force and effect or
become unenforceable or invalid or are declared null and void (other than in accordance with the
terms of such Guarantees) or the Guarantor denies or disaffirms its obligations under such
Guarantees.

     If an Event of Default (other than an Event of Default referred to in clause (iv) of the
preceding paragraph) with respect to this Security occurs and is continuing, the Trustee by notice

Exhibit A-9

 

to the Company and the Guarantor, or by the Holders of at least 25% in aggregate principal
amount of the then outstanding Securities by written notice to the Company, the Guarantor and the
Trustee, may declare all of the then outstanding Securities to be due and payable immediately. If
an Event of Default referred to in such clause (iv) occurs, acceleration of all amounts payable on
the Securities shall be automatic. The amount due and payable upon the acceleration of any Security
is equal to 100% of the principal amount thereof plus premium, if any, Additional Amounts, if any,
and accrued and unpaid interest to the date of payment. Holders may not enforce the Indenture or
this Security except as provided in the Indenture. The Trustee does require indemnity reasonably
satisfactory to it before it enforces the Indenture or this Security. Subject to certain
limitations, Holders of a majority in aggregate principal amount of the then outstanding Securities
may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders
notice of any continuing default (except a default in payment of principal, premium, if any,
Additional Amounts, if any, or interest) if it determines that withholding notice is in their
interests. Each of the Company and the Guarantor must furnish an annual compliance certificate to
the Trustee.

     11. Additional Amounts. If the Company or the Guarantor is required to withhold or deduct any
amount for or on account of any Taxes for any payment made under or with respect to this Security,
it will pay any Additional Amounts.

     12. Discharge or Defeasance Prior to Maturity. The Indenture shall be satisfied and
discharged upon the payment of all of the Securities, and it may be satisfied and discharged
(except for certain obligations) upon the irrevocable deposit with the Trustee of cash, or U.S.
Government Obligations or a combination thereof sufficient for such payment. The Indenture also
contains provisions for defeasance of (i) the entire indebtedness of the Company on the Securities
and (ii) certain restrictive covenants and the related Events of Default, subject to compliance by
the Company with certain conditions set forth in the Indenture.

     13. Trustee Dealings with the Company and the Guarantor. The Trustee in its individual or any
other capacity may become the owner or pledgee of this Security and may otherwise deal with the
Company, the Guarantor or any of their Affiliates with the same rights it would have if it were not
the Trustee.

     14. No Recourse Against Others. A director, officer, employee or stockholder of the Company
or the Guarantor, as such, shall not have any liability for any obligations of the Company or the
Guarantor under this Security, the Guarantees or the Indenture or for any claim based on, in
respect of or by reason of such obligations or their creation. Each Holder by accepting this
Security waives and releases all such liability. The waiver and release are part of the
consideration for the issuance of this Security.

     15. Authentication. This Security shall not be entitled to any benefit under the Indenture or
be valid or obligatory for any purpose until authenticated by the manual signature of an authorized
signatory of the Trustee, which signature shall be conclusive evidence that this Security has been
authenticated under the Indenture.

     16. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused a CUSIP number to be

Exhibit A-10

 

printed on this Security as a convenience to the Holders of this Security. No representation is made as to the
correctness of such number either as printed on this Security or as contained in any notice of a
redemption and that reliance may be placed only on the other identification numbers printed on this
Security.

     17. Abbreviations. Customary abbreviations may be used in the name of a Holder or an
assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (=
joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and
U/G/M/A (= Uniform Gifts to Minors Act).

     18. [Additional Rights of Holders of Restricted Global Securities and Restricted Definitive
Securities. In addition to the rights provided to Holders of Securities under the Indenture,
Holders of Securities will have the rights set forth in the Registration Rights Agreement, dated as
of February 20, 2008, among the Company, the Guarantor and the other parties named on the signature
pages
thereof.]*

     19. Governing Law. The Indenture, this Security and the Guarantees shall be governed by and
constructed in accordance with, the laws of the State of New York.

     The Company will furnish to any Holder upon written request and without charge a copy of the
Indenture. Request may be made to it at:

     Reference is hereby made to the Indenture, dated as of February 20, 2008 (the “Indenture”),
among Nabors Industries, Inc., as issuer (the “Company”), Nabors Industries Ltd., as guarantor (the
“Guarantor”), and Wells Fargo Bank, National Association, as trustee. Capitalized terms used but
not defined herein shall have the meanings given to them in the Indenture.

                          (the “Transferor”) owns and proposes to transfer the Security[ies] or
beneficial interest in such Security[ies] specified in Annex A hereto, in the principal amount of
$                     (the “Transfer”), to                      (the “Transferee”), as further specified in Annex A
hereto. In connection with the Transfer, the Transferor hereby certifies that:

[CHECK ALL THAT APPLY]

     1. [   ] CHECK IF TRANSFEREE IS A QIB IN ACCORDANCE WITH RULE 144A. The Transfer is being
effected pursuant to and in accordance with Rule 144A under the U.S. Securities Act of 1933, as
amended (the “Securities Act”), and, accordingly, the Transferor hereby further certifies that the
beneficial interest or Definitive Security is being transferred to a Person that the Transferor
reasonably believes is purchasing the beneficial interest or Definitive Security for its own
account, or for one or more accounts with respect to which such Person exercises sole investment
discretion, and such Person and each such account is a “qualified institutional buyer” within the
meaning of Rule 144A in a transaction meeting the requirements of Rule 144A, and such Transfer is
in compliance with any applicable blue sky securities laws of any state of the United States. Upon
consummation of the proposed Transfer in accordance with the terms of the Indenture, the
transferred beneficial interest or Definitive Security will be subject to the restrictions on

United States and (x) at the time the buy order was

Exhibit B-1

 

originated, the Transferee was outside the United States or such Transferor and any Person

of the Restricted Period, the Transfer is not being made to a U.S. Person or for the account or
benefit of a U.S. Person (other than an Initial Purchaser). Upon consummation of the proposed
transfer in accordance with the terms of the Indenture, the transferred beneficial interest or
Definitive Security will be subject to the restrictions on transfer enumerated in the Private
Placement Legend printed on the Regulation S Global Security or the Restricted Definitive Security
and in the Indenture and the Securities Act.

     3. [   ] CHECK IF TRANSFEREE WILL TAKE DELIVERY PURSUANT TO ANY PROVISION OF THE SECURITIES ACT
OTHER THAN RULE 144A OR REGULATION S. The Transfer is being effected in compliance with the
transfer restrictions applicable to beneficial interests in Restricted Global Securities and
Restricted Definitive Securities and pursuant to and in accordance with the Securities Act (other
than Rule 144A or Regulation S) and any applicable “blue sky” securities laws of any state of the
United States.

     4. [   ] CHECK AND COMPLETE IF TRANSFEREE WILL TAKE DELIVERY OF A BENEFICIAL INTEREST IN AN
UNRESTRICTED GLOBAL SECURITY OR OF AN UNRESTRICTED DEFINITIVE SECURITY:

          (a) [   ] CHECK IF TRANSFER IS PURSUANT TO RULE 144. (i) The Transfer is being effected pursuant
to and in accordance with Rule 144 under the Securities Act and in compliance with the transfer
restrictions contained in the Indenture and any applicable blue sky securities laws of any state of
the United States and (ii) the restrictions on transfer contained in the Indenture and the Private
Placement Legend are not required in order to maintain compliance with the Securities Act. Upon
consummation of the proposed Transfer in accordance with the terms of the Indenture, the
transferred beneficial interest or Definitive Security will no longer be subject to the
restrictions on transfer enumerated in the Private Placement Legend printed on the Restricted
Global Securities or Restricted Definitive Securities and in the Indenture.

          (b) [   ] CHECK IF TRANSFER IS PURSUANT TO REGULATION S. (i) The Transfer is being effected
pursuant to and in accordance with Rule 904 under the Securities Act and in compliance with the
transfer restrictions contained in the Indenture and any applicable blue sky securities laws of any
state of the United States and (ii) the restrictions on transfer contained in the Indenture and the
Private Placement Legend are not required in order to maintain compliance with the Securities Act.
Upon consummation of the proposed Transfer in accordance with the terms of the Indenture, the
transferred beneficial interest or Definitive Security will no longer be subject to the
restrictions on transfer enumerated in the Private Placement Legend printed on the Restricted
Global Securities or Restricted Definitive Securities and in the Indenture.

Exhibit B-2

 

          (c) [   ] CHECK IF TRANSFER IS PURSUANT TO OTHER EXEMPTION. (i) The Transfer is being effected
pursuant to and in compliance with an exemption from the registration requirements of the
Securities Act other than Rule 144 or Rule 904 and in compliance with the transfer restrictions
contained in the Indenture and any applicable blue sky securities laws of any state of the United
States and (ii) the restrictions on transfer contained in the Indenture and the Private Placement
Legend are not required in order to maintain compliance with the Securities Act. Upon consummation

Securities and in the Indenture.

rely on the position of the Commission in Morgan Stanley and Co., Inc. (pub. avail.

the resales are of New Securities obtained by such Holder in exchange for Securities
acquired by such Holder directly from the Company or one of its Affiliates. Accordingly,
each Holder participating in the Registered Exchange

5

 

Offer shall be required to represent to the Company and the Guarantor that, at the time

market-making activities or other trading activities and that it will deliver a
prospectus in connection with any resale of such New Securities.

          3. Shelf Registration.

          (a) If (i) due to any change in law or applicable interpretations thereof by the
Commission’s staff, the Company determines upon advice of its outside counsel that it is not
permitted to effect the Registered Exchange Offer as contemplated by Section 2 hereof;
(ii) for any other reason the Exchange Offer Registration Statement is not declared
effective by August 20, 2008 or the Registered Exchange Offer is not consummated by October
20, 2008; (iii) the Initial Purchasers determine upon advice of their counsel that a Shelf
Registration Statement must be filed in connection with any public offering or sale of
Securities that are not eligible to be exchanged for New Securities in the Registered
Exchange Offer and that are held by them following consummation of the Registered Exchange
Offer; or (iv) any Holder (other than the Initial Purchasers) is not eligible to participate
in the Registered Exchange Offer or does not receive freely tradeable New Securities in the
Registered Exchange Offer other than by reason of such Holder being an Affiliate of the
Company (it being understood that the requirement that a participating Broker-Dealer deliver
the prospectus contained in the Exchange Offer Registration Statement in connection with
sales of New Securities shall not result in such New Securities being not “freely
tradeable”), the Company and the Guarantor shall effect a Shelf Registration Statement in
accordance with subsection (b) below.

          (b) If required pursuant to subsection (a) above,

          (i)   the Company and the Guarantor, at their cost, shall as promptly as
practicable, but in no event later than 90 days after such obligation to file
arises, file with the Commission and cause to be declared effective under the

6

 

Act as soon as practicable, but in no event later than October 19, 2008, a
Shelf Registration Statement relating to the offer and sale of the Securities or the
New Securities, as applicable, by the Holders thereof from time to time in
accordance with the methods of distribution elected by such Holders and set forth in
such Shelf Registration Statement; provided, however, that no Holder
(other than the Initial Purchasers) shall be entitled to have the Securities or New
Securities held by it covered by such Shelf Registration Statement unless such
Holder agrees in writing to be bound by all of the provisions of this Agreement
applicable to such Holder; and provided further, that with respect
to New Securities received by the Initial Purchasers in exchange for Securities
constituting any portion of an unsold allotment, the Company and the Guarantor may,
if permitted by current interpretations by the Commission’s staff, file a
post-effective amendment to the Exchange Offer Registration Statement containing the
information required by Item 507 or 508 of Regulation S-K, as applicable, in
satisfaction of their obligations under this subsection with respect thereto, and
any such Exchange Offer Registration Statement, as so amended, shall be referred to
herein as, and governed by the provisions herein applicable to, a Shelf Registration
Statement.

          (ii) the Company and the Guarantor shall use their reasonable best efforts to
keep the Shelf Registration Statement continuously effective, supplemented and
amended as required by the Act, in order to permit the Prospectus forming part
thereof to be usable by Holders for a period the earlier of (A) the time when all of
the Securities or New Securities, as applicable, covered by the Shelf Registration
Statement can be sold pursuant to Rule 144 without limitation by non-affiliates of
the Company under clause (d) of Rule 144, (B) the date on which all the Securities
or New Securities, as applicable, covered by the Shelf Registration Statement have
been sold pursuant to the Shelf Registration Statement, and (C) one year from the
date the Shelf Registration Statement is declared effective by the Commission (in
any such case, such period being called the “Shelf Registration Period”). The
Company and the Guarantor shall be deemed not to have used their reasonable best
efforts to keep the Shelf Registration Statement effective during the requisite
period if they voluntarily take any action that would result in Holders of
Securities or New Securities covered thereby not being able to offer and sell such
Securities or New Securities during that period, unless (A) such action is required
by applicable law; or (B) such action is taken by the Company and the Guarantor in
good faith and for valid business reasons (not including avoidance of the Company’s
and the Guarantor’ obligations hereunder), including, but not limited to, the
acquisition or divestiture of assets, so long as the Company and the Guarantor
promptly thereafter comply with the requirements of Section 5(k) hereof, if
applicable.

          (iii) the Company and the Guarantor shall cause the Shelf Registration
Statement and the related Prospectus and any amendment or supplement thereto, as of
the effective date of the Shelf Registration Statement or such amendment or
supplement, (A) to comply in all material respects with the applicable requirements
of the Securities Act and the rules and regulations of the Commission; and (B) not
to contain any untrue statement of a material fact or

7

 

omit to state a material fact required to be stated therein or necessary in
order to make the statements therein, in the light of the circumstances under which
they were made, not misleading.

          4. Special Interest. If (a) on or prior to October 20, 2008, the Registered Exchange
Offer has not been consummated, or (b) after either the Exchange Offer Registration Statement or
the Shelf Registration Statement has been declared effective, such Registration Statement
thereafter ceases to be effective or usable in connection with resales of Securities or New
Securities in accordance with and during the periods specified in this Agreement (each such event
referred to in clauses (a) and (b), a (“Registration Default”), then, as liquidated damages,
interest (“Special Interest”) will accrue on the principal amount of the Securities and the New
Securities (in addition to the stated interest on the Securities and New Securities) from and
including the date on which any such Registration Default shall occur to but excluding the date on
which all Registration Defaults have been cured. Special Interest will accrue at a rate of 0.25%
per annum.

          All obligations of the Company and the Guarantor set forth in the preceding paragraph that are
outstanding with respect to any Security at the time such Security is exchanged for a New Security
shall survive until such time as all such obligations with respect to such Security have been
satisfied in full.

          5. Additional Registration Procedures. In connection with any Shelf Registration
Statement and, to the extent applicable, any Exchange Offer Registration Statement, the following
provisions shall apply.

requested by the Initial Purchasers or any such Holder or Exchanging Dealer shall confirm
such advice in writing (which notice pursuant to clauses (ii)-(v) hereof shall be
accompanied by an instruction to suspend the use of the Prospectus until the Company and the
Guarantor shall have remedied the basis for such suspension):

          (i) when a Registration Statement and any amendment thereto has been filed with
the Commission and when the Registration Statement or any post-effective amendment
thereto has become effective;

          (ii) of any request by the Commission for any amendment or supplement to the
Registration Statement or the Prospectus or for additional information;

effectiveness of the Registration Statement or the initiation of any proceedings for
that purpose;

          (iv) of the receipt by the Company and the Guarantor of any notification with

Statement or the Prospectus so that, as of such date, the statements therein are not
misleading and do not omit to state a material fact required to be stated therein or

9

 

case of the Prospectus, in the light of the circumstances under which they were
made) not misleading.

          (d) The Company and the Guarantor shall use their reasonable best efforts to obtain the

qualification of the Securities or New Securities therein for sale in any jurisdiction at
the earliest possible time.

          (e) The Company and the Guarantor shall furnish to each Holder of Securities or New
Securities covered by any Shelf Registration Statement, without charge, at least one copy of
such Shelf Registration Statement and any post-effective amendment thereto, and, if the
Holder so requests in writing, all material incorporated therein by reference and all
exhibits thereto (including exhibits incorporated by reference therein).

          (f) The Company and the Guarantor shall, during the Shelf Registration Period, deliver
to each Holder of Securities or New Securities covered by any Shelf Registration Statement,
without charge, as many copies of the Prospectus (including each preliminary Prospectus)
included in such Shelf Registration Statement and any amendment or supplement thereto as
such Holder may reasonably request. The Company and the Guarantor consent to the use of the
Prospectus or any amendment or supplement thereto by each of the selling Holders of
Securities or New Securities in connection with the offering and sale of the Securities or
New Securities covered by the Prospectus, or any amendment or supplement thereto, included
in the Shelf Registration Statement.

          (g) The Company and the Guarantor shall furnish to each Exchanging Dealer or the
Initial Purchasers which so requests, without charge, at least one copy of the Exchange
Offer Registration Statement and any post-effective amendment thereto, including all
material incorporated by reference therein, and, if the Exchanging Dealer so requests in
writing, all exhibits thereto (including exhibits incorporated by reference therein).

          (h) The Company and the Guarantor shall promptly deliver to the Initial Purchasers,
each Exchanging Dealer and each other Person required to deliver a Prospectus during the
Exchange Offer Registration Period, without charge, as many copies of the Prospectus
included in such Exchange Offer Registration Statement and any amendment or supplement
thereto as any such Person may reasonably request. The Company and the Guarantor consent to
the use of the Prospectus or any amendment or supplement thereto by the Initial Purchasers,
any Exchanging Dealer and any such other Person that may be required to deliver a Prospectus
following the Registered Exchange Offer in connection with the offering and sale of the New
Securities covered by the Prospectus, or any amendment or supplement thereto, included in
the Exchange Offer Registration Statement.

          (i) Prior to the Registered Exchange Offer or any other offering of Securities or New
Securities pursuant to any Registration Statement, the Company and the Guarantor shall
arrange, if necessary, for the qualification of the Securities or the

10

 

New Securities for sale under the laws of such jurisdictions as any Holder shall
reasonably request and will maintain such qualification in effect so long as required;
provided that in no event shall the Company and the Guarantor be obligated to qualify to do
business in any jurisdiction where they are not then so qualified or to take any action that
would subject them to service of process in suits or taxation, other than those arising out
of the Initial Placement, the Registered Exchange Offer or any offering pursuant to a Shelf
Registration Statement, in any such jurisdiction where they are not then so subject.

          (j) The Company and the Guarantor shall cooperate with the Holders of Securities and
New Securities to facilitate the timely preparation and delivery of certificates
representing New Securities or Securities to be issued or sold pursuant to any Registration
Statement free of any restrictive legends and in such denominations and registered in such
names as Holders may request.

          (k) Upon the occurrence of any event contemplated by subsections (c)(ii) through (v)
above, the Company and the Guarantor shall promptly prepare a post-effective amendment to
the applicable Registration Statement or an amendment or supplement to the related
Prospectus or file any other required document so that, as thereafter delivered to the
Initial Purchasers or Exchanging Dealers, the Prospectus will not include an untrue
statement of a material fact or omit to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were made, not
misleading. In such circumstances, the period of effectiveness of the Exchange Offer
Registration Statement provided for in Section 2 and the Shelf Registration Statement
provided for in Section 3(b) shall each be extended by the number of days from and including
the date of the giving of a notice of suspension pursuant to Section 5(c) to and including
the date when the Initial Purchasers, the Holders of the Securities or New Securities and
any known Exchanging Dealer shall have received such amended or supplemented Prospectus
pursuant to this Section.

          (l) Not later than the effective date of any Registration Statement, the Company and
the Guarantor shall provide a CUSIP number for the Securities or the New Securities, as the
case may be, registered under such Registration Statement and provide the Trustee with
printed certificates for such Securities or New Securities, in a form eligible for deposit
with The Depository Trust Company.

          (m) The Company and the Guarantor shall comply with all applicable rules and
regulations of the Commission and shall make generally available to their security holders
as soon as practicable after the effective date of the applicable Registration Statement an
earnings statement satisfying the provisions of Section 11(a) of the Act.

          (n) The Company and the Guarantor shall cause the Indenture or the New Securities
Indenture, as the case may be, to be qualified under the Trust Indenture Act in a timely
manner.

          (o) The Company and the Guarantor may require each Holder of Securities or New
Securities to be sold pursuant to any Shelf Registration Statement to furnish to the Company
and the Guarantor such information regarding the Holder and the

11

 

distribution of such Securities as the Company and the Guarantor may from time to time
reasonably require for inclusion in such Registration Statement. The Company and the
Guarantor may exclude from such Shelf Registration Statement the Securities or New
Securities of any Holder that fails to furnish such information within a reasonable time
after receiving such request.

          (p) In the case of any Shelf Registration Statement, the Company and the Guarantor
shall enter into such agreements and take all other appropriate actions (including if
requested an underwriting agreement in customary form) in order to expedite or facilitate
the registration or the disposition of the Securities or New Securities, and in connection
therewith, if an underwriting agreement is entered into, cause the same to contain
indemnification provisions and procedures no less favorable than those set forth in Section
7 (or such other provisions and procedures acceptable to the Majority Holders and the
Managing Underwriters, if any, with respect to all parties to be indemnified pursuant to
Section 7).

          (q) In the case of any Shelf Registration Statement, the Company and the Guarantor
shall use their reasonable best efforts to:

          (i) make reasonably available for inspection by the Holders of Securities or
New Securities to be registered thereunder, any Underwriter participating in any
disposition pursuant to such Registration Statement, and any attorney, accountant or
other agent retained by the Holders or any such Underwriter all relevant financial
and other records, pertinent corporate documents and properties of the Company and
its subsidiaries;

          (ii) cause the Company’s officers, directors and employees to supply all
relevant information reasonably requested by the Holders or any such Underwriter,
attorney, accountant or agent in connection with any such Registration Statement as
is customary for similar due diligence examinations; provided,
however, that any information that is designated in writing by the Company,
in good faith, as confidential at the time of delivery of such information shall be
kept confidential by the Holders or any such Underwriter, attorney, accountant or
agent, unless such disclosure is made in connection with a court proceeding or
required by law, or such information becomes available to the public generally or
through a third party without an accompanying obligation of confidentiality;

          (iii) make such representations and warranties to the Holders of Securities or
New Securities registered thereunder and the Underwriters, if any, in form,
substance and scope as are customarily made by issuers to Underwriters in primary
underwritten offerings and covering matters including, but not limited to, those set
forth in the Purchase Agreement;

          (iv) obtain opinions of counsel to the Company and the Guarantor and updates
thereof (which counsel and opinions (in form, scope and substance) shall be
reasonably satisfactory to the Managing Underwriters, if any)

12

 

addressed to each selling Holder and the Underwriters, if any, covering such
matters as are customarily covered in opinions requested in underwritten offerings
and such other matters as may be reasonably requested by such Holders and
Underwriters;

          (v) obtain “cold comfort” letters and updates thereof from the independent
certified public accountants of the Company (and, if necessary, any other
independent certified public accountants of any subsidiary of the Company or of any
business acquired by the Company for which financial statements and financial data
are, or are required to be, included in the Registration Statement), addressed to
each selling Holder of Securities or New Securities registered thereunder and the
Underwriters, if any, in customary form and covering matters of the type customarily
covered in “cold comfort” letters in connection with primary underwritten offerings;
and

          (vi) deliver such documents and certificates as may be reasonably requested by
the Majority Holders and the Managing Underwriters, if any, including those to
evidence compliance with Section 5(k) and with any customary conditions contained in
the underwriting agreement or other agreement entered into by the Company and the
Guarantor.

The actions set forth in clauses (iii), (iv), (v) and (vi) of this Section shall be performed at
(A) the effectiveness of such Registration Statement and each post-effective amendment thereto; and
(B) each closing under any underwriting or similar agreement as and to the extent required
thereunder.

          (r) If a Registered Exchange Offer is to be consummated, upon delivery of the
Securities by Holders to the Company (or to such other Person as directed by the Company) in
exchange for the New Securities, the Company shall mark, or caused to be marked, on the
Securities so exchanged that such Securities are being canceled in exchange for the New
Securities. In no event shall the Securities be marked as paid or otherwise satisfied.

          (s) If any Broker-Dealer shall underwrite any Securities or New Securities or
participate as a member of an underwriting syndicate or selling group or “assist in the
distribution” (within the meaning of the Rules of Fair Practice and the By-Laws of the
Financial Industry Regulatory Authority, Inc.) thereof, whether as a Holder of such
Securities or New Securities or as an Underwriter, a placement or sales agent or a broker or
dealer in respect thereof, or otherwise, will assist such Broker-Dealer in complying with
the requirements of such Rules and By-Laws, including, without limitation, by:

          (i) if such Rules or By-Laws shall so require, engaging a “qualified
independent underwriter” (as defined in such Rules) to participate in the
preparation of the Registration Statement, to exercise usual standards of due
diligence with respect thereto and, if any portion of the offering contemplated by
such Registration Statement is an underwritten offering or is made through a

13

 

placement or sales agent, to recommend the yield of such Securities or New
Securities;

          (ii) indemnifying any such qualified independent underwriter to the extent of
the indemnification of Underwriters provided in Section 7 hereof; and

          (iii) providing such information to such Broker-Dealer as may be required in
order for such Broker-Dealer to comply with the requirements of such Rules.

          (t) The Company and the Guarantor shall use their reasonable best efforts to take all
other steps necessary to effect the registration of the Securities or the New Securities, as
the case may be, covered by a Registration Statement.

          6. Registration Expenses. The Company and the Guarantor shall bear all expenses
incurred in connection with the performance of their obligations under Sections 2, 3 and 5 hereof
and, in the event of any Shelf Registration Statement, will reimburse the Holders for the
reasonable fees and disbursements of one firm or counsel designated by the Majority Holders to act
as counsel for the Holders in connection therewith, but excluding fees and expenses of counsel to
the Initial Purchasers or the Holders, all agency fees and commissions, underwriting discounts and
commissions and transfer taxes attributable to the sale or disposition of Securities by a Holder.

          7. Indemnification and Contribution.

          (a) The Company and the Guarantor agree, jointly and severally, to indemnify and hold
harmless (i) the Initial Purchasers, (ii) each Holder of Securities or New Securities, as
the case may be, covered by any Registration Statement (including with respect to any
Prospectus delivery as contemplated in Section 5(h) hereof, each Exchanging Dealer), (iii)
each Person, if any, who controls (within the meaning of either Section 15 of the Securities
Act or Section 20 of the Exchange Act) any of the foregoing (any of the Persons referred to
in this clause (iii) being hereinafter referred to as a “controlling person”), and (iv) the
respective officers, directors, partners, employees, representatives and agents of the
Initial Purchasers, the Holders (including predecessor Holders) or any controlling person
(any person referred to in clause (i), (ii), (iii) or (iv) may hereinafter be referred to as
an “Indemnified Holder”), from and against any and all losses, claims, damages, and
liabilities (including, without limitation, reasonable legal fees and other expenses
incurred in connection with any suit, action or proceeding or any claim asserted)
(collectively “Losses”) caused by any untrue statement or alleged untrue statement of a
material fact contained in any Registration Statement, preliminary Prospectus, Prospectus,
Free Writing Prospectus or any “issuer information” (as defined in Rule 433 of the
Securities Act) filed or required to be filed pursuant to Rule 433(d) under the Securities
Act, or any amendment or supplement thereto, or caused by any omission or alleged omission
to state therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as such losses, claims, damages or
liabilities are caused by any untrue statement or omission or alleged

14

 

untrue statement or omission made in reliance upon and in conformity with information
relating to any Indemnified Holder furnished to the Company or the Guarantor in writing by
such Indemnified Holder expressly for use therein; the Company or the Guarantor shall notify
such Indemnified Holder promptly of the institution, threat or assertion of any claim,
proceeding (including any governmental investigation) or litigation in connection with the
matters addressed by this Agreement which involves the Company or the Guarantor or such
Indemnified Holder.

          (b) Each Holder agrees, severally and not jointly, to indemnify and hold harmless the
Company and the Guarantor, each of their respective directors and officers and each Person
who controls the Company or the Guarantor within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing
indemnity from the Company and the Guarantor to each Holder, but only with reference to such
losses, claims, damages or liabilities which are caused by any untrue statement or omission
or alleged untrue statement or omission made in reliance upon and in conformity with
information relating to a Holder furnished to the Company or the Guarantor in writing by
such Holder expressly for use in any Registration Statement, preliminary Prospectus or
Prospectus, or any amendment or supplement thereto. This indemnity agreement will be in
addition to any liability which any such Holder may otherwise have.

          (c) Each of the Initial Purchasers, severally and not jointly, agrees to indemnify and
hold harmless the Company and the Guarantor, each of their respective directors and officers
and each Person who controls the Company or the Guarantor within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the
foregoing indemnity from the Company and the Guarantor to the Initial Purchasers, but only
with reference to such losses, claims, damages or liabilities which are caused by any untrue
statement or omission or alleged untrue statement or omission made in reliance upon and in
conformity with information relating to the Initial Purchasers furnished to the Company or
the Guarantor in writing by the Initial Purchasers expressly for use in any Registration
Statement, preliminary Prospectus or Prospectus, or any amendment or supplement thereto.
This indemnity agreement will be in addition to any liability which the Initial Purchasers
may otherwise have.

          (d) If any suit, action, proceeding (including any governmental or regulatory
investigation), claim or demand shall be brought or asserted against any Person in respect
of which indemnity may be sought pursuant to either of the three preceding paragraphs, such
Person (the “Indemnified Person”) shall promptly notify the Person or Persons against whom
such indemnity may be sought (each an “Indemnifying Person”) in writing, and such
Indemnifying Person, upon request of the Indemnified Person, shall retain counsel reasonably
satisfactory to the Indemnified Person to represent the Indemnified Person and any others
entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may
designate in such proceeding and shall pay the fees and expenses of such counsel related to
such proceeding. In any such proceeding, the Indemnifying Person shall be able to
participate in such proceeding and, to the extent that it so elects, jointly with any other
similarly situated Indemnifying Person, to assume the defense thereof, subject to the right
of the Indemnified Person to be separately

15

 

represented and to direct its own defense if the named parties to any such proceeding
include both the Indemnified Person and the Indemnifying Person and the Indemnified Person
has been advised by counsel that representation of both parties by the same counsel would be
inappropriate due to actual or potential differing interests between them. In any such
proceeding, any Indemnified Person shall have the right to retain its own counsel, but the
fees and expenses of such counsel shall be at the expense of such Indemnified Person unless
(i) such Indemnifying Person and the Indemnified Person shall have mutually agreed to the
contrary or (ii) the named parties in any such proceeding (including any impleaded parties)
include an Indemnifying Person and an Indemnified Person and representation of both parties
by the same counsel would be inappropriate due to actual or potential differing interests
between them. It is understood that an Indemnifying Person shall not, in connection with
any proceeding or related proceedings in the same jurisdiction, be liable for the fees and
expenses of more than one separate firm (in addition to any local counsel) for all
Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are
incurred. Any such separate firm for the Indemnified Holders shall be designated in writing
by the Holders of the majority in amount of Securities and New Securities offered in the
Prospectus to which the claim relates, any such separate firm for the Company, its
directors, respective officers and such control Persons of the Company shall be designated
in writing by the Company, and any such separate firm for the Guarantor, its directors,
respective officers and such control Persons of the Guarantor shall be designated in writing
by the Guarantor. The Indemnifying Person shall not be liable for any settlement of any
proceeding effected without its written consent, but if settled with such consent or if
there be a final judgment for the plaintiff, such Indemnifying Person agrees to indemnify
any Indemnified Person from and against any loss or liability by reason of such settlement
or judgment. No Indemnifying Person shall, without the prior written consent of the
Indemnified Person, effect any settlement of any pending or threatened proceeding in respect
of which any Indemnified Person is or could have been a party and indemnity could have been
sought hereunder by such Indemnified Person, unless such settlement includes an
unconditional release of such Indemnified Person from all liability on claims that are the
subject matter of such proceeding.

          (e) If the indemnification provided for in the first, second and third paragraphs of
this Section 7 is unavailable to an Indemnified Person or insufficient in respect of any
losses, claims, damages or liabilities referred to therein, then each Indemnifying Person
under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall
contribute to the amount paid or payable by such Indemnified Person as a result of such
losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect
the relative benefits received by the Indemnifying Person on the one hand and the
Indemnified Person on the other hand pursuant to the Purchase Agreement or from the offering
of the Securities or New Securities pursuant to any Registration Statement which resulted in
such losses, claims, damages or liabilities or (ii) if the allocation provided by clause (i)
above is not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause (i) above but also the relative fault
of the Indemnifying Person on the one hand and the Indemnified Person on the other in
connection with the statements or omissions that resulted in such losses, claims, damages or
liabilities, as well as any other relevant

16

 

equitable considerations. The relative benefits received by the Company and the
Guarantor on the one hand and any Indemnified Holder on the other shall be deemed to be in
the same proportion as the total net proceeds from the Initial Placement received by the
Company and the Guarantor bear to the total net proceeds received by such Indemnified Holder
from sales of Securities or New Securities giving rise to such obligations. The relative
fault of the parties shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged omission to
state a material fact relates to information supplied by the Company or the Guarantor or
such Indemnified Holder and the parties’ relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

          (f) Each of the Company, the Guarantor and the Initial Purchasers agree that it would
not be just and equitable if contribution pursuant to this Section 7 were determined by pro
rata allocation or by any other method of allocation that does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The amount
paid or payable by an Indemnified Person as a result of the losses, claims, damages and
liabilities referred to in the immediately preceding paragraph shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses incurred by such
Indemnified Person in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 7, in no event shall any Holder of any
Securities or New Securities be required to contribute any amount in excess of the amount by
which the net proceeds received by such Holder from the sale of the Security or New Security
pursuant to a Registration Statement exceeds the amount of damages which such Holder would
have otherwise been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any
Person who was not guilty of such fraudulent misrepresentation.

          (g) The remedies provided for in this Section 7 are not exclusive and shall not limit
any rights or remedies that may otherwise be available to any indemnified party at law or in
equity.

          (h) The indemnity and contribution agreements contained in this Section 7 shall remain
operative and in full force and effect regardless of (i) any termination of this Agreement,
(ii) any investigation made by or on behalf of any Holder or any Person controlling any
Holder or by or on behalf of the Company or the Guarantor, their respective officers or
directors or any other Person controlling any of the Company or the Guarantor and (iii)
acceptance of and payment for any of the Securities or New Securities.

          8. Underwritten Registrations.

          (a) If any of the Securities or New Securities, as the case may be, covered by any
Shelf Registration Statement are to be sold in an underwritten offering, the

17

 

Managing Underwriters shall be selected by the Majority Holders and shall be reasonably
satisfactory to the Company and the Guarantor.

          (b) No Person may participate in any underwritten offering pursuant to any Shelf
Registration Statement, unless such Person (i) agrees to sell such Person’s Securities or
New Securities, as the case may be, on the basis reasonably provided in any underwriting
arrangements approved by the Persons entitled hereunder to approve such arrangements; and
(ii) completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms of such
underwriting arrangements.

          9. No Inconsistent Agreements. The Company has not, as of the date hereof, entered
into, nor shall it, on or after the date hereof, enter into, any agreement with respect to its
securities that is inconsistent with the rights granted to the Holders herein or otherwise
conflicts with the provisions hereof.

          10. Amendments and Waivers. The provisions of this Agreement, including the
provisions of this sentence, may not be amended, qualified, modified or supplemented, and waivers
or consents to departures from the provisions hereof may not be given, unless the Company has
obtained the written consent of the Majority Holders (or, after the consummation of any Registered
Exchange Offer in accordance with Section 2 hereof, of New Securities); provided,
however, that, with respect to any matter that directly or indirectly affects the rights of
the Initial Purchasers hereunder, the Company shall obtain the written consent of the Initial
Purchasers. Notwithstanding the foregoing (except the foregoing proviso), a waiver or consent to
departure from the provisions hereof with respect to a matter that relates exclusively to the
rights of Holders whose Securities or New Securities, as the case may be, are being sold pursuant
to a Registration Statement and that does not directly or indirectly affect the rights of other
Holders may be given by the Majority Holders, determined on the basis of Securities or New
Securities, as the case may be, being sold rather than registered under such Registration
Statement.

          11. Notices. All notices and other communications (including without limitation any
notices or other communications to the Trustee) provided for or permitted hereunder shall be made
in writing by hand-delivery, registered first-class mail, next-day air courier or facsimile:

          The Initial Purchasers or the Company by notice to the other parties may designate additional

          12. Successors. This Agreement shall inure to the benefit of and be binding upon the
successors and assigns of each of the parties, including, without the need for an express

19

 

assignment or any consent by the Company thereto, subsequent Holders of Securities or New
Securities. The Company hereby agrees to extend the benefits of this Agreement to any Holder of
Securities and the New Securities, and any such Holder may specifically enforce the provisions of
this Agreement as if an original party hereto.

          13. Counterparts. This Agreement may be executed (including by facsimile) in any

the same agreement.

          14. Headings. The headings used herein are for convenience only and shall not affect

          16. Severability. If any one of more of the provisions contained herein, or the
application thereof in any circumstances, is held invalid, illegal or unenforceable in any respect
for any reason, the validity, legality and enforceability of any such provision in every other
respect and of the remaining provisions hereof shall not be in any way impaired or affected
thereby, it being intended that all of the rights and privileges of the parties shall be
enforceable to the fullest extent permitted by law.

          17. Securities Held by the Company, etc. Whenever the consent or approval of Holders
of a specified percentage of principal amount of Securities or New Securities is required
hereunder, Securities or New Securities, as applicable, held by the Company or its Affiliates
(other than subsequent Holders of Securities or New Securities if such subsequent Holders are
deemed to be Affiliates solely by reason of their holdings of such Securities or New Securities)
shall not be counted in determining whether such consent or approval was given by the Holders of
such required percentage.

          18. No Fiduciary Duty. The Company and Guarantor hereby acknowledge that (a) the
Initial Purchasers are acting as principal and not as an agent or fiduciary of the Company or the
Guarantor and (b) the Company’s engagement of the Initial Purchasers in connection with the
offering and the process leading up to the offering pursuant to the Purchase Agreement is as
independent contractors and not in any other capacity. Furthermore, the Company and the Guarantor
agree that they are solely responsible for making their own judgments in connection with the
offering, the Registered Exchange Offer or a Shelf Registration (irrespective of whether any of the
Initial Purchasers has advised or is currently advising the Company or the Guarantor on related or
other matters). The Company and the Guarantor agree that they will not claim that the Initial
Purchasers have rendered advisory services of any nature or respect, or owe an agency, fiduciary or
similar duty to the Company or the Guarantor, in connection with such transaction or the process
leading thereto

ANNEX A

          Each Broker-Dealer that receives New Securities for its own account pursuant to the Exchange
Offer must acknowledge that it will deliver a prospectus in connection with any resale of such New
Securities. The Letter of Transmittal states that by so acknowledging and by delivering a
prospectus, a Broker-Dealer will not be deemed to admit that it is an “underwriter” within the
meaning of the Securities Act. This Prospectus, as it may be amended or supplemented from time to
time, may be used by a Broker-Dealer in connection with resales of New Securities received in
exchange for Securities where such Securities were acquired by such Broker-Dealer as a result of
market-making activities or other trading activities. The Company has agreed that, starting on the
Expiration Date (as defined herein) and ending on the close of business one year after the
Expiration Date, or such shorter period as will terminate when all New Securities held by
Exchanging Dealers or Initial Purchasers have been sold pursuant hereto, it will make this
Prospectus available to any Broker-Dealer for use in connection with any such resale. Furthermore,
any broker-dealer that acquired any of the old notes directly from us:

	 	•	 	may not rely on the applicable interpretation of the staff of the SEC’s position
contained in Exxon Capital Holdings Corporation (pub. avail. May 13, 1988),
Morgan Stanley and Co., Inc. (pub. avail. June 5, 1991), ), as interpreted
in the Commission’s letter to Shearman & Sterling dated July 2, 1993 and similar
no-action letters; and
	 
	 	•	 	must also be named as a selling noteholder in connection with the registration
and prospectus delivery requirements of the Securities Act relating to any resale
transaction.

See “Plan of Distribution.”

ANNEX B

          Each Broker-Dealer that receives New Securities for its own account in exchange for
Securities, where such Securities were acquired by such Broker-Dealer as a result of market-making
activities or other trading activities, must acknowledge that it will comply with the registration
and prospectus delivery requirements of the Securities Act in connection with any offer, resale or
other transfer of such New Securities, including information with respect to any selling holder
required by the Securities Act in connection with the resale of the New Securities. See “Plan of
Distribution.”

ANNEX C

PLAN OF DISTRIBUTION

          Each Broker-Dealer that receives New Securities for its own account pursuant to the Exchange
Offer must acknowledge that it will deliver a prospectus in connection with any resale of such New
Securities. This Prospectus, as it may be amended or supplemented from time to time, may be used
by a Broker-Dealer in connection with resales of New Securities received in exchange for Securities
where such Securities were acquired as a result of market-making activities or other trading
activities. We have agreed that, starting on the Expiration Date and ending on the close of
business 180-days after the Expiration Date or such shorter period as will terminate when all New
Securities held by Exchanging Dealers or Initial Purchasers have been sold pursuant hereto, we will
make this Prospectus, as amended or supplemented, available to any Broker-Dealer for use in
connection with any such resale. In addition, until ______, 200___, all dealers effecting
transactions in the New Securities may be required to deliver a prospectus.

          We will not receive any proceeds from any sale of New Securities by brokers-dealers. New
Securities received by Broker-Dealers for their own account pursuant to the Exchange Offer may be
sold from time to time in one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the New Securities or a combination of such methods
of resale, at market prices prevailing at the time of resale, at prices related to such prevailing
market prices or negotiated prices. Any such resale may be made directly to purchasers or to or
through brokers or dealers who may receive compensation in the form of commissions or concessions
from any such Broker-Dealer and/or the purchasers of any such New Securities. Any Broker-Dealer
that resells New Securities that were received by it for its own account pursuant to the Exchange
Offer and any broker or dealer that participates in a distribution of such New Securities may be
deemed to be an “underwriter” within the meaning of the Securities Act and any profit of any such
resale of New Securities and any commissions or concessions received by any such Persons may be
deemed to be underwriting compensation under the Securities Act. The Letter of Transmittal states
that by acknowledging that it will deliver and by delivering a prospectus, a Broker-Dealer will not
be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.

          Furthermore, any broker-dealer that acquired any of the old notes directly from us:

	 	•	 	may not rely on the applicable interpretation of the staff of the SEC’s position
contained in Exxon Capital Holdings Corporation (pub. avail. May 13, 1988),
Morgan Stanley and Co., Inc. (pub. avail. June 5, 1991), ), as interpreted
in the Commission’s letter to Shearman & Sterling dated July 2, 1993 and similar
no-action letters; and
	 
	 	•	 	must also be named as a selling noteholder in connection with the registration
and prospectus delivery requirements of the Securities Act relating to any resale
transaction.

26

 

          For a period of 180-days after the Expiration Date or such shorter period as will terminate
when all New Securities held by Exchanging Dealers or Initial Purchasers have been sold pursuant
hereto, we will promptly send additional copies of this Prospectus and any amendment or supplement
to this Prospectus to any Broker-Dealer that requests such documents in the Letter of Transmittal.
We have agreed to pay all expenses incident to the Exchange Offer (including the expenses of one
counsel for the holder of the Securities) other than commissions or concessions of any brokers or
dealers and will indemnify the holders of the Securities (including any Broker-Dealers) against
certain liabilities, including liabilities under the Securities Act.

          [If applicable, add information required by Regulation S-K Items 507 and/or 508.]
