If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of Outstanding Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date.

(f) The Trustee shall set a record date, which shall not be more than 15 days prior to the date of commencement of solicitation of such action contemplated by this Section 1.04(f), for the purpose of determining the Holders of Securities of any series entitled to join in the giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 4.02, (iii) any direction referred to in Section 4.12, (iv) any request to institute proceedings referred to in Section 4.07(2), or (v) any waiver of past defaults pursuant to Section 4.13, in each case with respect to Securities of such series. If such a record date is fixed pursuant to this paragraph, the relevant action may be taken or given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be holders of Securities of a series for the purpose of determining whether Holders of the requisite proportion of Outstanding Securities of such series have authorized or agreed or consented to such action, and for that purpose the Outstanding Securities of such series shall be computed as of such record date; provided that no such action by Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be canceled and of no effect), and nothing in this paragraph shall

13

be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date and the proposed action by Holders to be given to the Company in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 1.06.

SECTION 1.05. Notices, Etc., to Trustee and Company. Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with,

(c) In respect of this Indenture, the Trustee shall not have any duty or obligation to verify or confirm that the Person sending instructions, directions, reports, notices or other communications or information by electronic transmission is, in fact, a Person authorized to give such instructions, directions, reports, notices or other communications or information on behalf of the party purporting to send such electronic transmission; and the Trustee shall not have any liability for any losses, liabilities, costs or expenses incurred or sustained by any party as a result of such reliance upon or compliance with such instructions, directions, reports, notices or other communications or information; provided such losses, liabilities, costs or expenses have not arisen from the fraud, gross negligence or willful misconduct of the Trustee. Each other party agrees to assume all risks arising out of the use of electronic methods to submit instructions, directions, reports, notices or other communications or information to the Trustee, including without limitation the risk of the Trustee acting on unauthorized instructions, notices, reports or other communications or information, and the risk of interception and misuse by third parties.

14

SECTION 1.06. Notice to Holders; Waiver. Where this Indenture or any Security provides for notice to Holders of any event, such notice shall be deemed sufficiently given (unless otherwise herein or in such Security expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders or the validity of the proceedings to which such notice relates.

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

Any request, demand, authorization, direction, notice, consent or waiver required or permitted under this Indenture shall be in the English language, except that any published notice may be in an official language of the country of publication.

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

SECTION 1.07. Conflict with Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with another provision hereof which is required to be included or deemed included in this Indenture by any of the provisions of the Trust Indenture Act, such required provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, such provision of the Trust Indenture Act shall be deemed to apply to this Indenture as so modified or shall be excluded, as the case may be.

SECTION 1.08. Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

SECTION 1.09. Successors and Assigns. All covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not.

SECTION 1.10. Separability Clause. In case any provision in this Indenture or in the Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 1.11. Benefits of Indenture. Nothing in this Indenture or in the Securities, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder and the Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture.

15

SECTION 1.12. Governing Law. This Indenture and the Securities shall be governed by and construed in accordance with the laws (other than the choice of law provisions) of the State of New York.

SECTION 1.13. Legal Holidays. In any case where any Interest Payment Date, Redemption Date, sinking fund payment date, Stated Maturity or Maturity of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities other than a provision in the Securities of any series which specifically states that such provision shall apply in lieu of this Section) payment of interest or principal (and premium, if any) need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day or on such other day as may be set out in the Officers’ Certificate pursuant to Section 2.01 at such Place of Payment with the same force and effect as if made on the Interest Payment Date, Redemption Date, sinking fund payment date, Stated Maturity or Maturity, as the case may be, provided that no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date, Redemption Date, sinking fund payment date, Stated Maturity or Maturity, as the case may be, if payment is made on such next succeeding Business Day or other day set out in such Officers’ Certificate.

SECTION 1.14. No Recourse Against Others. A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under the Securities or this Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Securityholder, by accepting a Security, waives and releases all such liability. Such waivers and releases are part of the consideration for the issuance of the Securities.

SECTION 1.15. Judgment Currency. The Company agrees, to the fullest extent that it may effectively do so under applicable law, that (a) if for the purpose of obtaining judgment in any court it is necessary to convert the sum due in respect of the principal of, or premium or interest, if any, on the Securities of any series (the “Required Currency” ) into a currency in which a judgment will be rendered (the “Judgment Currency” ), the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Trustee could purchase in the City of New York the Required Currency with the Judgment Currency on the New York Banking Day preceding that on which a final unappealable judgment is given and (b) its obligations under this Indenture to make payments in the Required Currency (i) shall not be discharged or satisfied by any tender, or any recovery pursuant to any judgment (whether or not entered in accordance with subsection (a)), in any currency other than the Required Currency, except to the extent that such tender or recovery shall result in the actual receipt, by the payee, of the full amount of the Required Currency expressed to be payable in respect of such payments, (ii) shall be enforceable as an alternative or additional cause of action for the purpose of recovering in the Required Currency the amount, if any, by which such actual receipt shall fall short of the full amount of the Required Currency so expressed to be payable and (iii) shall not be affected by judgment being obtained for any other sum due under this Indenture. For purposes of the foregoing, “New York Banking Day” means any day except a Saturday, Sunday or a legal holiday in the City of New York or a day on which banking institutions in the City of New York are authorized or required by law, regulation, or executive order to close.

16

SECTION 1.16. Counterparts. This instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument.

SECTION 1.17. Waiver of Jury Trial. Each of the Company and the Trustee hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all rights to trial by jury in any legal proceeding arising out of or relating to the Indenture, the Securities or the transactions contemplated hereby.

All Securities of any one series shall be substantially identical except as to denomination and except as may otherwise be provided (i) by a Board Resolution, and (subject to Section 2.04) set forth, or determined in the manner provided, in an Officers’ Certificate or (ii) in any such indenture supplemental hereto. All Securities of any one series need not be issued at the same time and, unless otherwise provided, a series may be reopened, without the consent of the Holders, for issuances of additional Securities of such series.

If any of the terms of the Securities of any series are established by action taken pursuant to a Board Resolution, a copy of an appropriate record of such action shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate setting forth, or providing the manner for determining, the terms of the Securities of such series, and an appropriate record of any action taken pursuant thereto in connection with the issuance of any Securities of such series shall be delivered to the Trustee prior to the authentication and delivery thereof.

SECTION 2.02. Forms Generally. The Securities of each series shall be in substantially the form established by or pursuant to a Board Resolution or in one or more indentures supplemental hereto, in each case with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by this Indenture, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be required to comply with the rules of any securities exchange or as may, consistently herewith, be determined by the Officers executing such Securities, as evidenced by their execution of the Securities. If the form of Securities of any series is established by action taken pursuant to a Board Resolution, a copy of an appropriate record of such action shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Company Order contemplated by Section 2.04 for the authentication and delivery of such Securities.

19

SECTION 2.03. Denominations. The Securities of each series shall be issuable in registered form without coupons in such denominations as shall be specified as contemplated by Section 2.01. In the absence of any such provisions with respect to the Securities of any series, the Securities of such series shall be issuable in denominations of $1,000 and any integral multiple of $1,000.

SECTION 2.04. Execution, Authentication, Delivery and Dating. The Securities shall be executed on behalf of the Company by its Chairman of the Board, President and Chief Executive Officer, Chief Financial Officer, Secretary or any Vice President of the Corporation under its corporate seal reproduced thereon attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Securities may be manual or facsimile. The seal of the Company may be in the form of a facsimile thereof and may be impressed, affixed, imprinted or otherwise reproduced on the Securities. Typographical and other minor errors or defects in any such reproduction of the seal or any such signature shall not affect the validity or enforceability of any Security that has been duly authenticated and delivered by the Trustee.

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

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Company Order shall authenticate and make such Securities available for delivery. If the form or terms of the Securities of the series have been established in or pursuant to one or more Board Resolutions or in a supplemental indenture as permitted by Sections 2.01 and 2.02, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Sections 315(a) through (d) of the Trust Indenture Act) shall be fully protected in relying upon, an Opinion of Counsel stating,

(a) if the form of such Securities has been established by or pursuant to a Board Resolution or in a supplemental indenture as permitted by Section 2.02, that such form has been established in conformity with the provisions of this Indenture;

(b) if the terms of such Securities have been established by or pursuant to Board Resolution or in a supplemental indenture as permitted by Section 2.01, that such terms have been established in conformity with the provisions of this Indenture; and

(c) that such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, enforceable in accordance with their terms, except to the extent enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and other similar laws affecting the enforcement of creditors’ rights generally and by the effect of general principles of equity (regardless of whether enforceability is considered in a proceeding in equity or at law).

20

Notwithstanding the provisions of Section 2.01 and of the immediately preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the Board Resolution and the Officers’ Certificate otherwise required pursuant to Section 2.01 or the Company Order and Opinion of Counsel otherwise required pursuant to the immediately preceding paragraph at or prior to the time of authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued.

If such form or terms have been so established, the Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee, or in the written opinion of counsel to the Trustee (which counsel may be an employee of the Trustee) such authentication may not lawfully be made or could involve the Trustee in personal liability.

If the Company shall establish pursuant to Section 2.01 that the Securities of a series are to be issued in whole or in part in the form of one or more global Securities, then the Company shall execute and the Trustee shall, in accordance with this Section and the Company Order with respect to the authentication and delivery of such series, authenticate and deliver one or more Securities of such series in global form that (i) shall be in an aggregate amount equal to the aggregate principal amount of the Outstanding Securities of such series to be represented by such Security or Securities in global form, (ii) shall be registered in the name of the Depositary for such Security or Securities in global form or its nominee, and (iii) shall be made available for delivery by the Trustee to such Depositary or pursuant to such Depositary’s instruction.

Each Depositary designated pursuant to Section 2.01 for a Security in global form must, at the time of its designation and at all times while it serves as Depositary, be a clearing agency registered under the Exchange Act and any other applicable statute or regulation. The Trustee shall have no responsibility to determine if the Depositary is so registered. Each Depositary shall enter into an agreement with the Trustee and the Company governing the respective duties and rights of such Depositary, the Company and the Trustee with regard to Securities issued in global form.

Unless otherwise provided for in the form of Security, each Security shall be dated the date of its authentication.

No Security shall be entitled to any benefits under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee or an Authenticating Agent by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture.

21

Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 2.10 together with a written statement (which need not comply with Section 1.02 and need not be accompanied by an Opinion of Counsel) stating that such Security has never been issued and sold by the Company, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall not be entitled to the benefits of this Indenture.

SECTION 2.05. Temporary Securities. Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee shall authenticate and make available for delivery, temporary Securities of such series which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities.

In the case of Securities of any series, such temporary Securities may be in global form, representing all or a portion of the Outstanding Securities of such series.

Except in the case of temporary Securities in global form (which shall be exchanged in accordance with the provisions thereof), if temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the Company shall execute and the Trustee shall authenticate and make available for delivery in exchange therefor a like principal amount of definitive Securities of the same series of authorized denominations and of like tenor. Until so exchanged, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series.

SECTION 2.06. Registration, Registration of Transfer and Exchange. The Company shall cause to be kept at the Corporate Trust Office of the Trustee or in any office or agency to be maintained by the Company in accordance with Section 9.02 in a Place of Payment a register (the register maintained in such office and in any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the “Security Register” ) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of registration of transfers of Securities. The Trustee is hereby appointed “Security Registrar” for the purpose of registering Securities and transfers of Securities as herein provided.

Upon surrender for registration of transfer of any Security of any series at the office or agency of the Company in a Place of Payment for that series, the Company shall execute, and the Trustee shall authenticate and make available for delivery, in the name of the designated transferee or transferees, one or more new Securities of the same series, of any authorized denominations and of a like aggregate principal amount and Stated Maturity.

22

At the option of the Holder, Securities of any series (except a Security in global form) may be exchanged for other Securities of the same series, of any authorized denominations and of a like aggregate principal amount and Stated Maturity, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and make available for delivery, the Securities which the Holder making the exchange is entitled to receive.

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

Notwithstanding any other provision of this Section, unless and until it is exchanged in whole or in part for Securities in certificated form in the circumstances described below, a Security in global form representing all or a portion of the Securities of a series may not be transferred except as a whole by the Depositary for such series to a nominee of such Depositary or by a nominee of such Depositary to such Depositary or another nominee of such Depositary or by such Depositary or any such nominee to a successor Depositary for such series or a nominee of such successor Depositary.

If at any time the Depositary for the Securities of a series notifies the Company that it is unwilling or unable to continue as Depositary for the Securities of such series or defaults in the performance of its duties as Depositary or if at any time the Depositary for the Securities of such series shall no longer be eligible under Section 2.04, the Company shall appoint a successor Depositary with respect to the Securities of such series. If a successor Depositary for the Securities of such series is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such ineligibility, the Company shall execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of certificated Securities of such series of like tenor, shall authenticate and deliver Securities of such series of like tenor in certificated form, in authorized denominations and in an aggregate principal amount equal to the principal amount of the Security or Securities of such series of like tenor in global form in exchange for such Security or Securities in global form.

The Company may at any time in its sole discretion determine that Securities issued in global form shall no longer be represented by such a Security or Securities in global form. In such event the Company shall execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of certificated Securities of such series of like tenor, shall authenticate and deliver, Securities of such series of like tenor in certificated form, in authorized denominations and in an aggregate principal amount equal to the principal amount of the Security or Securities of such series of like tenor in global form in exchange for such Security or Securities in global form.

If specified by the Company pursuant to Section 2.01 with respect to a series of Securities, the Depositary for such series may surrender a Security in global form of such series

23

in exchange in whole or in part for Securities of such series in certificated form on such terms as are acceptable to the Company and such Depositary. Thereupon, the Company shall execute, and the Trustee shall authenticate and deliver, without service charge,

(i) to each Person specified by such Depositary a new certified Security or Securities of the same series of like tenor, of any authorized denomination as requested by such Person in aggregate principal amount equal to and in exchange for such Person’s beneficial interest in the Security in global form; and

(ii) to such Depositary a new Security in global form of like tenor in a denomination equal to the difference, if any, between the principal amount of the surrendered Security in global form and the aggregate principal amount of certificated Securities delivered to Holders thereof.

Upon the exchange of a Security in global form for Securities in certificated form, such Security in global form shall be canceled by the Trustee. Securities issued in exchange for a Security in global form pursuant to this Section shall be registered in such names and in such authorized denominations as the Depositary for such Security in global form, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Securities to the Persons in whose names such Securities are so registered.

Whenever any Securities are surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive.

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

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

Unless otherwise provided in the Securities to be transferred or exchanged, no service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 2.05, 8.06 or 10.07 not involving any transfer.

If the Securities of any series (or of any series and specified tenor) are to be redeemed in part, the Company shall not be required (i) to issue, register the transfer of or exchange Securities of such series during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of Securities of that series selected for redemption under Section 10.03 and ending at the close of business on the day of such mailing, or (ii) to register the transfer of or exchange any Security so selected for redemption, in whole or in part, except the unredeemed portion of any Security being redeemed in part.

24

The foregoing provisions relating to registration, transfer and exchange may be modified, supplemented or superseded with respect to any series of Securities by a Board Resolution or in one or more indentures supplemental hereto.

SECTION 2.07. Mutilated, Destroyed, Lost and Stolen Securities. If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

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

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

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

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

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

SECTION 2.08. Payment of Interest; Interest Rights Preserved. Interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest.

25

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

(1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment (which shall be not less than 25 days after the receipt by the Trustee of such notice, unless such Trustee shall consent to an earlier date), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Securities of such series at his address as it appears in the Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2).

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

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

SECTION 2.09. Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of, premium, if any, and (subject to Sections 2.06 and 2.08) interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

None of the Company, the Trustee or any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interest of a Security in global form, or for maintaining,

26

supervising or reviewing any records relating to such beneficial ownership interest. Notwithstanding the foregoing, with respect to any Security in global form, nothing herein shall prevent the Company or the Trustee or any agent of the Company or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by any Depositary (or its nominee), as a Holder, with respect to such Security in global form or impair, as between such Depositary and owners of beneficial interests in such Security in global form, the operation of customary practices governing the exercise of the right of such Depositary (or its nominee) as holder of such Security in global form.

SECTION 2.10. Cancellation. All Securities surrendered for payment, redemption, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly canceled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly canceled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section, except as expressly permitted by this Indenture. All canceled Securities shall be held by the Trustee and may be destroyed (and, if so destroyed, certification of their destruction shall be delivered to the Company, unless, by a Company Order, the Company shall direct that canceled Securities be returned to it).

SECTION 2.11. Computation of Interest. Except as otherwise specified as contemplated by Section 2.01 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a year comprised of twelve 30-day months.

SECTION 2.12. CUSIP Number. The Company in issuing Securities of any series may use a “CUSIP” number, and if so, the Trustee may use the CUSIP number in notices of redemption or exchange as a convenience to Holders of such series; provided , that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number printed on the notice or on the Securities of such series, 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 the CUSIP number of any series of Securities.

SECTION 2.13. Wire Transfers. Notwithstanding any other provision to the contrary in this Indenture, the Company may make any payment of moneys required to be deposited with the Trustee on account of principal of, or premium, if any, or interest on the Securities (whether pursuant to optional or mandatory redemption payments, interest payments or otherwise) by wire transfer of immediately available funds to an account designated by the Trustee on or before the date and time such moneys are to be paid to the Holders of the Securities in accordance with the terms hereof.

SECTION 2.14. Original Issue Discount. The Company shall file with the Trustee promptly at the end of each calendar year (i) a written notice specifying the amount of original issue discount (including daily rates and accrual periods) accrued on Outstanding Securities as of the end of such year (ii) such other specific information relating to such original issue discount as may then be relevant under the Internal Revenue Code of 1986, as amended from time to time.

ARTICLE 3

SATISFACTION AND DISCHARGE

SECTION 3.01. Satisfaction and Discharge of Indenture. This Indenture shall cease to be of further effect with respect to Securities of a particular series (except as to any surviving rights of registration of transfer or exchange of Securities and replacement of such Securities which may have been lost, stolen or mutilated as herein expressly provided for or in the form of Security for such series), when the Trustee, upon Company Request and at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture with respect to such Securities, when

(1) either (a) all Securities of such series theretofore authenticated and delivered (other than (i) Securities which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.07 and (ii) Securities of such series for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 9.08) have been delivered to the Trustee for cancellation; or (b) all such Securities not theretofore delivered to the Trustee for cancellation (i) have become due and payable, or (ii) will become due and payable at their Stated Maturity within one year, or (iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and the Company, in the case of (b)(i), (ii) or (iii) above, has deposited with the Trustee as trust funds in trust for the purpose an amount, in the currency or currencies or currency unit or units in which the Securities of such series are payable, sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal, premium, if any, and interest to the date of such deposit (in the case of Securities which have become due and payable) or the Stated Maturity or Redemption Date, as the case may be;

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

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

Notwithstanding the satisfaction and discharge of this Indenture with respect to the Securities of any series, the obligations of the Company to the Trustee under Section 5.07, the obligations of the Company to any Authenticating Agent under Section 5.14 and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (1) of this Section, the obligations of the Trustee under Section 3.02 and the last paragraph of Section 9.08 shall survive.

SECTION 3.02. Application of Trust Money. Subject to the provisions of the last paragraph of Section 9.08, all money deposited with the Trustee pursuant to Section 3.01 shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of

28

the principal (and premium, if any) and interest for whose payment such money has been deposited with or received by the Trustee, but such money need not be segregated from other funds except to the extent required by law.

ARTICLE 4

REMEDIES

SECTION 4.01. Events of Default. “Event of Default,” wherever used herein with respect to Securities of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or to be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

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

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

(3) the Company fails to deposit any sinking fund payment, when and as due by the terms of a Security of that series; or

(4) the Company fails to observe or perform in any material respect any of its other covenants, agreements or warranties in the Securities of that series or this Indenture (other than a covenant, agreement or warranty a default in whose performance or whose breach is elsewhere in this Section specifically dealt with or which has expressly been included in this Indenture solely for the benefit of a series of Securities other than that series), and the failure to observe or perform continues for the period and after the notice specified in the last paragraph of this Section; or

(5) an event of default, as defined in any mortgage, indenture, or instrument under which there may be issued, or by which there may be secured or evidenced, any Indebtedness of the Company (including Securities of another series) (other than the Securities of such series) (whether such Indebtedness now exists or shall hereafter be created or incurred) shall occur and shall result in Indebtedness becoming or being declared due and payable prior to the date on which it would otherwise become due and payable, and such default in payment is not cured or such acceleration shall not be rescinded or annulled within 10 days after written notice to the Company from the Trustee or to the Company and to the Trustee from the Holders of at least twenty-five percent in aggregate principal amount of the Outstanding Securities of that series specifying such event of default and requiring the Company to cure such default in payment or cause such acceleration to be rescinded or annulled and stating that such notice is a “Notice of Default” hereunder; provided , however , that it shall not be an Event of Default if the principal amount of Indebtedness which is not paid at maturity or the maturity of which is accelerated is equal to or less than $50,000,000; provided further that if, prior to a declaration of acceleration of the maturity of the Securities of that series or the entry of judgment in favor of the Trustee in a suit pursuant to Section 4.03, such default shall be remedied or cured by the Company or waived

29

by the holders of such Indebtedness, then the Event of Default hereunder by reason thereof shall be deemed likewise to have been thereupon remedied, cured or waived without further action upon the part of either the Trustee or any of the Holders of the Securities of that series, and provided further , that, subject to Sections 5.01 and 5.02, the Trustee shall not be charged with knowledge of any such default unless written notice of such default shall have been given to the Trustee by the Company, by a holder or an agent of a holder of any such Indebtedness, by the trustee then acting under any indenture or other instrument under which such default shall have occurred, or by the Holders of at least five percent in aggregate principal amount of the Securities of that series at the time outstanding; or

(6) the Company or any of its Restricted Subsidiaries pursuant to or within the meaning of any Bankruptcy Law (A) commences a voluntary case or proceeding under any Bankruptcy Law with respect to itself, (B) consents to the entry of a judgment, decree or order for relief against it in an involuntary case or proceeding under any Bankruptcy Law, (C) consents to or acquiesces in the institution of bankruptcy or insolvency proceedings against it, (D) applies for, consents to or acquiesces in the appointment of or taking possession by a Custodian of it or for all or substantially all of its property, (E) makes a general assignment for the benefit of its creditors or (F) takes any corporate action in furtherance of or to facilitate, conditionally or otherwise, any of the foregoing; or

(7) (i) a court of competent jurisdiction enters a judgment, decree or order for relief in an involuntary case or proceeding under any Bankruptcy Law which shall (A) approve as properly filed a petition seeking reorganization, arrangement, adjustment or composition in respect of the Company or any of its Restricted Subsidiaries, (B) appoint a Custodian of the Company or any of its Restricted Subsidiaries or for all or substantially all of its property or (C) order the winding-up or liquidation of affairs of the Company or any of its Restricted Subsidiaries, and such judgment, decree or order shall remain unstayed and in effect for a period of 90 consecutive days; or (ii) any bankruptcy or insolvency petition or application is filed, or any bankruptcy or insolvency proceeding is commenced, against the Company or any of its Restricted Subsidiaries and such petition, application or proceeding is not dismissed or stayed within 60 days; or (iii) a warrant of attachment is issued against any material portion of the property of the Company or any of its Restricted Subsidiaries which is not released within 60 days of service; or

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

A Default under clause (4) above is not an Event of Default until the Trustee or the Holders of at least twenty-five percent in aggregate principal amount of the Outstanding Securities of that series notify the Company of the Default and the Company does not cure the Default within 60 days after receipt of the notice. The notice must specify the Default, demand that it be remedied and state that the notice is a “Notice of Default.” When a Default under clause (4) above is cured within such 60-day period, it ceases to be a Default.

SECTION 4.02. Acceleration of Maturity; Rescission and Annulment. If an Event of Default with respect to Securities of any series (other than an Event of Default specified in clause (6) or (7) of Section 4.01) occurs and is continuing, the Trustee by notice in writing to the Company, or the Holders of at least twenty-five percent in aggregate principal amount of the

30

Outstanding Securities of that series by notice in writing to the Company and the Trustee, may declare the unpaid principal of and accrued interest to the date of acceleration (or, if the Securities of that series are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of that series) on all the Outstanding Securities of that series to be due and payable immediately and, upon any such declaration, the Outstanding Securities of that series (or specified principal amount) shall become and be immediately due and payable.

If an Event of Default specified in clause (6) or (7) of Section 4.01 occurs, all unpaid principal of and accrued interest on the Outstanding Securities of that series (or specified principal amount) shall automatically become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder of any Security of that series.

Upon payment of all such principal and interest, all of the Company’s obligations under the Securities of that series and (upon payment of the Securities of all series) this Indenture shall terminate, except obligations under Section 5.07.

At any time after a declaration of acceleration of Maturity with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series by notice to the Trustee may rescind an acceleration and its consequences if (i) all existing Events of Default, other than the nonpayment of the principal of and interest on the Securities of that series that has become due solely by such declaration of acceleration, have been cured or waived, (ii) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal that has become due otherwise than by such declaration of acceleration have been paid, (iii) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (iv) all payments due to the Trustee and any predecessor Trustee under Section 5.07 have been made.

SECTION 4.03. Collection of Indebtedness and Suits for Enforcement by Trustee . The Company covenants that if:

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

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

(3) default is made in the payment of any sinking fund or analogous obligation when the same becomes due by the terms of the Securities of any series, and any such default continues for any period of grace provided with respect to the Securities of such series,

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

31

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

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

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

SECTION 4.04. Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the material property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise,

(i) to file and prove a claim for the whole amount of principal (and premium, if any) and interest owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceedings, and

(ii) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 5.07.

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.

32

SECTION 4.05. Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered.

SECTION 4.06. Application of Money Collected. Any money collected by the Trustee pursuant to this Article in respect of the Securities of any series shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal, premium, if any, or interest, upon presentation of the Securities in respect of which moneys have been collected and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

First: To the payment of all amounts due the Trustee under Section 5.07 applicable to such series;

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

Third: To the Company.

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 4.06. At least ten (10) 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 the amount to be paid.

SECTION 4.07. Limitation on Suits. No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

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

(2) the Holders of at least twenty-five percent in principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;

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

33

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

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

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

SECTION 4.08. Unconditional Right of Holders to Receive Principal, Premium and Interest. Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of, premium, if any, and (subject to Section 2.08) interest on such Security on the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder.

SECTION 4.09. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding has been instituted.

SECTION 4.10. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 2.07, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

SECTION 4.11. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

34

SECTION 4.12. Control by Holders. The Holders of a majority in principal amount of the Outstanding Securities of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series, provided that:

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

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

(3) subject to Section 5.01, the Trustee need not take any action which might involve the Trustee in personal liability or be unduly prejudicial to the Holders not joining therein.

SECTION 4.13. Waiver of Past Defaults. The Holders of not less than a majority in principal amount of the Outstanding Securities of any series may by written notice to the Trustee on behalf of the Holders of all the Securities of such series waive any Default or Event of Default with respect to such series and its consequences, except a Default or Event of Default

(1) in respect of the payment of the principal of or premium, if any, or interest on any Security of such series, or

(2) in respect of a covenant or other provision hereof which under Article 8 cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected.

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

SECTION 4.14. Undertaking for Costs. All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than ten percent in principal amount of the Outstanding Securities of any series, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or premium, if any, or interest on any Security on or after the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on or after the Redemption Date).

If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of such notice of removal, the Trustee being removed may petition, at the expense of the Company, any court of competent jurisdiction, for the appointment of a successor Trustee with respect to the Securities of such series.

(e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 5.11. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 5.11, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company with respect to such Securities. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 5.11, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

(f) The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee

with respect to the Securities of any series by mailing written notice of such event by first-class mail, postage prepaid, to all Holders of Securities of such series as their names and addresses appear in the Security Register. Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office.

SECTION 5.11. Acceptance of Appointment by Successor. (a) In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers, trusts and duties of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.

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

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

41

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

SECTION 5.12. Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor (by merger, conversion, consolidation or otherwise as permitted hereunder) to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

SECTION 5.13. Preferential Collection of Claims Against Company. The Trustee shall comply with Section 311(a) of the Trust Indenture Act, excluding any creditor relationship listed in Section 311(b) of the Trust Indenture Act. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the Trust Indenture Act to the extent indicated therein.

SECTION 5.14. Appointment of Authenticating Agent. At any time when any of the Securities remain Outstanding the Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of, and subject to the direction of, the Trustee to authenticate Securities of such series issued upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 2.07, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by federal or State authority. If such Authenticating Agent publishes or files reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published or filed. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.

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

42

be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

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

The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation as negotiated between the Company and such Authenticating Agent for its services under this Section.

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

43

to it with respect to payments of premium (if any) and interest on the Securities of any series, whether acting as Trustee, Security Registrar, Paying Agent or otherwise with respect to the Securities of any series.

SECTION 9.07. Waiver of Stay, Extension or Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim, and will actively resist any and all efforts to be compelled to 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 from paying all or any portion of the principal of and/or interest on the Securities as contemplated herein, wherever enacted, now or at any time hereafter

51

in force, or which may affect the covenants or the performance of this Indenture; and (to the extent that it may lawfully do so) the Company 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.

SECTION 9.08. Money for Securities Payments to be Held in Trust. If the Company shall at any time act as its own Paying Agent with respect to any series of Securities, it will, on or before each due date of the principal of (and premium, if any) or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal (and premium, if any) or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act.

Whenever the Company shall have one or more Paying Agents for any series of Securities, it will, prior to 10:00 a.m. at each Place of Payment on each due date of the principal of (and premium, if any) or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure to so act.

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

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

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

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

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

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of (and premium, if any) or interest on any Security of any series and remaining unclaimed for one year after such principal (and premium,

52

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

SECTION 9.09. Limitations on Liens. Unless the terms of a particular series of Securities otherwise provide, so long as any Securities of such series remain Outstanding, the Company will not, nor will it permit any Restricted Subsidiary to, issue, incur, create, assume or guarantee any Indebtedness secured by a mortgage, security interest, pledge, lien, charge or other encumbrance (mortgages, security interests, pledges, liens, charges and other encumbrances being hereinafter in this Article 9 referred to as “lien” or “liens” ) upon any assets of the Company or any Restricted Subsidiary (whether such assets are now existing or owned or hereafter created or acquired) without in any such case effectively providing concurrently with the issuance, incurrence, creation, assumption or guaranty of any such Indebtedness that the Securities of such series (together with, if the Company shall so determine, any other indebtedness of or guarantee by the Company or such Restricted Subsidiary ranking equally with the Securities of such series and then existing or thereafter created) shall be secured equally and ratably with (or, at the Company’s option, prior to) such secured Indebtedness until such time as such Indebtedness is no longer secured by a lien. The preceding sentence shall not require the Company to secure any Securities of such series if the lien consists of either of the following:

(a) Permitted Liens; or

(b) liens securing Indebtedness if, after giving pro forma effect to the incurrence, creation, assumption or guaranty of such Indebtedness (and the receipt and application of the proceeds thereof) or the securing of outstanding Indebtedness, the sum of (without duplication) (i) the aggregate principal amount of all such Indebtedness of the Company and its Subsidiaries secured by liens (other than Permitted Liens) upon the assets of the Company or any Restricted Subsidiary or, if less, the fair market value of the property subject to such lien, as determined in good faith by the Board of Directors and (ii) all Attributable Debt in respect of Sale and Lease-Back Transactions not otherwise permitted under the first sentence of Section 9.10, at the time of determination does not exceed fifteen percent of Consolidated Net Worth.

SECTION 9.10. Limitations on Sale and Lease-Back Transactions. Unless the terms of a particular series of Securities otherwise provide, so long as any Securities of such series remain Outstanding, the Company will not, nor will it permit any Restricted Subsidiary to, enter into any Sale and Lease-Back Transaction for a term of more than three years unless (a) the assets subject to the Sale and Lease-Back Transaction have not been owned by the Company or a Restricted Subsidiary or have not been in full operation for more than one year prior to the Sale and Lease-Back Transaction or (b) the Company or such Restricted Subsidiary would be entitled

53

to incur Indebtedness secured by a lien on such assets in an amount at least equal to the Attributable Debt with respect to such Sale and Lease-Back Transaction without equally and ratably securing the Securities of such series pursuant to Section 9.09 or (c) the Company, within 180 days after the effective date of such Sale and Lease-Back Transaction, applies an amount equal to the value of such assets to the Defeasance or retirement (other than any mandatory retirement, mandatory prepayment or sinking fund payment or by way of payment at maturity) of Securities or other Indebtedness of the Company or a Restricted Subsidiary that matures more than one year after the creation of such Indebtedness or to the purchase, construction or development of other comparable property or (d) the transaction is between the Company and one of its Restricted Subsidiaries. Notwithstanding the foregoing, the Company and its Restricted Subsidiaries shall be allowed to enter into Sale and Lease-Back Transactions if, after giving pro forma effect to such Sale and Lease-Back Transaction (and the receipt and application of proceeds thereof) the sum of (without duplication) (i) the aggregate principal amount of all Indebtedness of the Company and its Subsidiaries secured by liens (other than Permitted Liens) upon the assets of the Company or any Restricted Subsidiary or, if less, the fair market value of the property subject to such lien, as determined in good faith by the Board of Directors and (ii) all Attributable Debt in respect of Sale and Lease-Back Transactions not otherwise permitted under the first sentence of this Section 9.10 at the time of determination does not exceed fifteen percent of Consolidated Net Worth.

SECTION 9.11. Waiver of Certain Covenants. The Company may omit in any particular instance to comply with any term, provision or condition set forth in Sections 9.09 or 9.10 with respect to the Securities of any series if before the time for such compliance the Holders of not less than a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

SECTION 10.05. Deposit of Redemption Price.

Unless any Security by its terms prohibits any sinking fund payment obligation from being satisfied by delivering and crediting Securities (including Securities redeemed otherwise than through a sinking fund), the Company may deliver such Securities to the Trustee for crediting against such payment obligation in accordance with the terms of such Securities and this Indenture.

SECTION 10.06. Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest.
