(h) unless the context otherwise requires, any reference to an “Article,” “Section” or “clause” refers to an Article, Section or clause, as the case may be, of this Thirteenth Supplemental Indenture; and

(i) the words “herein,” “hereof” and “hereunder” and other words of similar import refer to this Thirteenth Supplemental Indenture as a whole and not any particular Article, Section, clause or other subdivision.

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

Section 1.05 Acts of Holders .

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Thirteenth Supplemental Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Issuer or the Parent Guarantor, as applicable. Proof of execution of any such instrument or of a writing appointing any such agent, or the holding by any Person of a Note, shall be sufficient for any purpose of this Thirteenth Supplemental Indenture and (subject to Section 7.01) conclusive in favor of the Trustee and the Issuer and the Parent Guarantor, as applicable, if made in the manner provided in this Section 1.05.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by the certificate of any notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by or on behalf of any legal entity other than an individual, such certificate or affidavit shall also constitute proof of the authority of the Person executing the same. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner that the Trustee deems sufficient.

(c) The ownership of Notes shall be proved by the Note Register.

(d) Any request, demand, authorization, direction, notice, consent, waiver or other action by the Holder of any Note shall bind every future Holder of the same Note and the Holder of

(e) The Issuer may, in the circumstances permitted by the Trust Indenture Act, set a record date for purposes of determining the identity of Holders entitled to give any request, demand, authorization, direction, notice, consent, waiver or take any other act, or to vote or consent to any action by vote or consent authorized or permitted to be given or taken by Holders. Unless otherwise specified, if not set by the Issuer prior to the first solicitation of a Holder made by any Person in respect of any such action, or in the case of any such vote, prior to such vote, any such record date shall be the later of 30 days prior to the first solicitation of such consent or the date of the most recent list of Holders furnished to the Trustee prior to such solicitation.

(f) Without limiting the foregoing, a Holder entitled to take any action hereunder with regard to any particular Note may do so with regard to all or any part of the principal amount of such Note or by one or more duly appointed agents, each of which may do so pursuant to such appointment with regard to all or any part of such principal amount. Any notice given or action taken by a Holder or its agents with regard to different parts of such principal amount pursuant to this paragraph shall have the same effect as if given or taken by separate Holders of each such different part.

(h) The Issuer may fix a record date for the purpose of determining the Persons who are beneficial owners of interests in any Global Note held by DTC entitled under the procedures of such depositary to make, give or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in this Thirteenth Supplemental Indenture to be made, given or taken by Holders. If such a record date is fixed, the Holders on such record date or their duly appointed proxy or proxies, and only such Persons, shall be entitled to make, give or take such request, demand, authorization, direction, notice, consent, waiver or other action, whether or not such Holders remain Holders after such record date. No such request, demand, authorization, direction, notice, consent, waiver or other action shall be valid or effective if made, given or taken more than 90 days after such record date.

ARTICLE 2

Section 2.01 Form and Dating; Terms .

(a) General . The Notes and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A hereto.

-14-

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

(c) Terms . The aggregate principal amount of Notes that may be authenticated and delivered under this Thirteenth Supplemental Indenture is unlimited.

The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Thirteenth Supplemental Indenture and the Issuer, the Parent Guarantor and the Trustee, by their execution and delivery of this Thirteenth Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this Thirteenth Supplemental Indenture, the provisions of this Thirteenth Supplemental Indenture shall govern and be controlling.

The Notes shall be subject to repurchase by the Issuer pursuant to a Change of Control Offer as provided in Section 4.10 hereof. The Notes shall not be redeemable, other than as provided in Article 3.

Additional Notes may be created and issued from time to time by the Issuer without notice to or consent of the Holders and shall be consolidated with and form a single class with the Initial Notes and shall have the same terms as to status, redemption or otherwise as the Initial Notes. Except as described under Article 9 hereof, the Notes offered by the Issuer and any Additional Notes subsequently issued under this Thirteenth Supplemental Indenture will be treated as a single class for all purposes under this Thirteenth Supplemental Indenture, including waivers, amendments, redemptions and offers to purchase. Unless the context requires otherwise, references to “Notes” for all purposes of this Thirteenth Supplemental Indenture include any Additional Notes that are actually issued. Any Additional Notes shall be issued with the benefit of an indenture supplemental to this Thirteenth Supplemental Indenture.

Section 2.02 Execution and Authentication .

At least one Officer shall execute the Notes on behalf of the Issuer by manual or facsimile signature.

If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note shall nevertheless be valid.

-15-

A Note shall not be entitled to any benefit under this Thirteenth Supplemental Indenture or be valid or obligatory for any purpose until authenticated substantially in the form provided for in Exhibit A attached hereto, by the manual signature of the Trustee. The signature shall be conclusive evidence that the Note has been duly authenticated and delivered under this Thirteenth Supplemental Indenture.

On the Issue Date, the Trustee shall, upon receipt of an Issuer Order (an “ Authentication Order ”), authenticate and deliver the Initial Notes. In addition, at any time, from time to time, the Trustee shall upon an Authentication Order authenticate and deliver any Additional Notes. Such Authentication Order shall specify the amount of the Notes to be authenticated.

The Trustee may appoint an authenticating agent acceptable to the Issuer to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Thirteenth Supplemental Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the Issuer.

Section 2.03 Registrar and Paying Agent .

The Issuer shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“ Registrar ”) and an office or agency where Notes may be presented for payment (“ Paying Agent ”). The Registrar shall keep a register of the Notes (“ Note Register ”) and of their transfer and exchange. The Issuer may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuer may change any Paying Agent or Registrar without prior notice to any Holder. The Issuer shall notify the Trustee in writing of the name and address of any Agent not a party to this Thirteenth Supplemental Indenture. If the Issuer fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Issuer or any of its Subsidiaries may act as Paying Agent or Registrar.

The Issuer initially appoints The Depository Trust Company (“ DTC ”) to act as Depositary with respect to the Global Notes.

The Issuer initially appoints Deutsche Bank Trust Company Americas to act as the Paying Agent, Registrar and Transfer Agent for the Notes and the Registrar to act as Custodian with respect to the Global Notes.

Section 2.04 Paying Agent to Hold Money in Trust .

The Issuer shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium, if any, or interest on the Notes, and will notify the Trustee of any default by the Issuer in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Issuer or a Subsidiary) shall have no further liability for the money. If the Issuer or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Issuer, the Trustee shall serve as Paying Agent for the Notes.

-16-

Section 2.05 Holder Lists .

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with Trust Indenture Act Section 312(a). If the Trustee is not the Registrar, the Issuer shall furnish to the Trustee at least two Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes and the Issuer shall otherwise comply with Trust Indenture Act Section 312(a).

Section 2.06 Transfer and Exchange .

(a) Transfer and Exchange of Global Notes . A Global Note may not be transferred except as a whole by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes will be exchanged by the Issuer for Definitive Notes if:

(A) the Issuer delivers to the Trustee notice from the Depositary that the Depositary is unwilling or unable to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Issuer within 120 days after the date of such notice from the Depositary;

(B) the Issuer in its sole discretion determines that the Global Notes (in whole but not in part) should be exchanged for Definitive Notes and delivers a written notice to such effect to the Trustee; or

(C) there has occurred and is continuing a Default or Event of Default with respect to the Notes, and the Depositary has notified the Issuer and the Trustee of its desire to exchange the Global Notes for Definitive Notes.

Upon the occurrence of either of the preceding events in (A) or (B) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, pursuant to this Section 2.06 or Sections 2.07 and 2.10 hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Sections 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged for another Note other than as provided in this Section 2.06(a), however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.06(b) or (c) hereof.

(b) Transfer and Exchange of Beneficial Interests in the Global Notes . The transfer and exchange of beneficial interests in the Global Notes will be effected through the Depositary, in accordance with the provisions of this Thirteenth Supplemental Indenture.

No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.06(b) and Section 2.06(d) hereof.

(c) Transfer or Exchange of Beneficial Interests for Definitive Notes . If any holder of a beneficial interest in a Global Note proposes to exchange such beneficial interest for a Definitive Note or to transfer such beneficial interest to a Person who takes delivery thereof in the form of a

-17-

Definitive Note, then, upon satisfaction of the conditions set forth in Section 2.06(b) hereof, the Trustee will cause the aggregate principal amount of the applicable Global Note to be reduced accordingly pursuant to Section 2.06(g) hereof, and the Issuer will execute and the Trustee will authenticate and deliver to the Person designated in the instructions a Definitive Note in the appropriate principal amount. Any Definitive Note issued in exchange for a beneficial interest pursuant to this Section 2.06(c) will be registered in such name or names and in such authorized denomination or denominations as the holder of such beneficial interest requests through instructions to the Registrar from or through the Depositary and the Participant or Indirect Participant. The Trustee will deliver such Definitive Notes to the Persons in whose names such Notes are registered.

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

(e) Transfer and Exchange of Definitive Notes for Definitive Notes . Upon request by a Holder of Definitive Notes and such Holder’s compliance with the provisions of this Section 2.06(e), the Registrar will register the transfer or exchange of Definitive Notes. Prior to such registration of transfer or exchange, the requesting Holder must present or surrender to the Registrar the Definitive Notes duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Registrar duly executed by such Holder or by its attorney, duly authorized in writing. In addition, the requesting Holder must provide any additional certifications, documents and information, as applicable, required pursuant to the following provisions of this Section 2.06(e). A Holder of Definitive Notes may transfer such Notes to a Person who takes delivery thereof in the form of a Definitive Note.

(f) Global Note Legend . Each Global Note shall bear a legend in substantially the following form:

“THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE THIRTEENTH SUPPLEMENTAL INDENTURE GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 2.06 OF THE THIRTEENTH SUPPLEMENTAL INDENTURE, (II) THIS GLOBAL NOTE MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 2.06(a) OF THE THIRTEENTH SUPPLEMENTAL INDENTURE, (III) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 2.11 OF THE THIRTEENTH SUPPLEMENTAL INDENTURE AND (IV) THIS GLOBAL NOTE MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF THE ISSUER.

OR SUCH OTHER ENTITY AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.”

(g) Cancellation and/or Adjustment of Global Notes . At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or cancelled in whole and not in part, each such Global Note shall be returned to or retained and cancelled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase.

(h) General Provisions Relating to Transfers and Exchanges .

(i) To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.02 hereof or at the Registrar’s request.

(ii) No service charge shall be made to a holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.07, 2.10, 3.06, 4.10 and 9.05 hereof).

(iii) Neither the Registrar nor the Issuer shall be required to register the transfer of or exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part.

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

(v) The Issuer shall not be required (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection, (B) to register the transfer of or to exchange any Note so selected for

Section 2.07 Replacement Notes .

If required by the Trustee or the Issuer, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuer to protect the Issuer, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuer and/or the Trustee may charge for their expenses in replacing a Note.

Every replacement Note is a contractual obligation of the Issuer and shall be entitled to all of the benefits of this Thirteenth Supplemental Indenture equally and proportionately with all other Notes duly issued hereunder.

Section 2.08 Outstanding Notes .

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note.

-20-

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

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

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

Section 2.09 Treasury Notes .

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer, or by any Affiliate of the Issuer, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee knows are so owned shall be so disregarded. Notes so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right to deliver any such direction, waiver or consent with respect to the Notes and that the pledgee is not the Issuer or any obligor upon the Notes or any Affiliate of the Issuer or of such other obligor.

Section 2.10 Temporary Notes .

Until certificates representing Notes are ready for delivery, the Issuer may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of certificated Notes but may have variations that the Issuer considers appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuer shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes.

Holders and beneficial holders, as the case may be, of temporary Notes shall be entitled to all of the benefits accorded to Holders, or beneficial holders, respectively, of Notes under this Thirteenth Supplemental Indenture.

Section 2.11 Cancellation .

The Issuer at any time may deliver Notes to the Trustee for cancellation.

Certification of the destruction of all cancelled Notes shall be delivered to the Issuer. The Issuer may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

Section 2.12 Defaulted Interest .

If the Issuer defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest to the Persons

-21-

who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Issuer shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment, and at the same time the Issuer 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 provided in this Section 2.12. The Trustee shall fix or cause to be fixed each such special record date and payment date; provided that no such special record date shall be less than 10 days prior to the related payment date for such defaulted interest. The Trustee shall promptly notify the Issuer of such special record date. At least 15 days before the special record date, the Issuer (or, upon the written request of the Issuer, the Trustee in the name and at the expense of the Issuer) shall mail or cause to be mailed, first-class postage prepaid, to each Holder a notice at his or her address as it appears in the Note Register that states the special record date, the related payment date and the amount of such interest to be paid.

Subject to the foregoing provisions of this Section 2.12 and for greater certainty, each Note delivered under this Thirteenth Supplemental Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note.

Section 2.13 CUSIP and ISIN Numbers .

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

ARTICLE 3

The Registrar and Paying Agent shall promptly notify the Issuer in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected shall be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; no Notes of $2,000 or less can be redeemed in part, except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not $2,000 or a multiple of $1,000 in excess thereof, shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Thirteenth Supplemental Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase.

If any Note called for redemption or purchase shall not be so paid upon surrender for redemption or purchase because of the failure of the Issuer to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest accrued to the redemption or purchase date not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof.

Section 3.06 Notes Redeemed or Purchased in Part .

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 6.11 Delay or Omission Not Waiver .

No delay or omission of the Trustee or of any Holder of any Note 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.

To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

-42-

Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes and the Guarantee on the date the conditions set forth below are satisfied (“ Legal Defeasance ”).

For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Issuer may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Thirteenth Supplemental Indenture and such Notes shall be unaffected thereby.

AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01 Without Consent of Holders of Notes .

Notwithstanding Section 9.02 hereof, the Issuer, the Parent Guarantor (with respect to the Guarantee or this Thirteenth Supplemental Indenture) and the Trustee may amend or supplement this Thirteenth Supplemental Indenture, Notes or the Guarantee without the consent of any Holder:

(1) to evidence the succession of another corporation to the Issuer or the Parent Guarantor and the assumption by such successor of the covenants of the Issuer or the Parent Guarantor in compliance with the requirements set forth in this Thirteenth Supplemental Indenture; or

(2) to add to the covenants for the benefit of the Holders or to surrender any right or power herein conferred upon the Issuer or the Parent Guarantor; or

(3) to add any additional Events of Default; or

(4) to change or eliminate any of the provisions of this Thirteenth Supplemental Indenture, provided that any such change or elimination shall become effective only when there are no outstanding Notes of any series created prior to the execution of such supplemental indenture that is entitled to the benefit of such provision and as to which such supplemental indenture would apply; or

(5) to secure the Notes; or

(6) to supplement any of the provisions of this Thirteenth Supplemental Indenture to such extent necessary to permit or facilitate the defeasance and discharge of the Notes, provided that any such action does not adversely affect the interests of the Holders of the Notes in any material respect; or

(7) to evidence and provide for the acceptance of appointment hereunder by a successor Trustee and to add to or change any of the provisions of this Thirteenth Supplemental Indenture necessary to provide for or facilitate the administration of the trusts by more than one Trustee; or

(8) to cure any ambiguity to correct or supplement any provision of this Thirteenth Supplemental Indenture which may be defective or inconsistent with any other provision; or

(9) to change any place or places where the principal of and premium, if any, and interest, if any, on the Notes shall be payable, the Notes may be surrendered for registration or transfer, the Notes may be surrendered for exchange, and notices and demands to or upon the Issuer may be served; or

-46-

(10) to comply with requirements of the SEC in order to effect or maintain the qualification of this Thirteenth Supplemental Indenture under the Trust Indenture Act; or

(11) to conform the text of this Thirteenth Supplemental Indenture, the Guarantee or the Notes to any provision of the “Description of the Notes” section of the Prospectus to the extent that such provision in such “Description of the Notes” section was intended to be a verbatim recitation of a provision of this Thirteenth Supplemental Indenture, the Guarantee or the Notes; or

(12) to make any amendment to the provisions of this Thirteenth Supplemental Indenture relating to the transfer and legending of Notes as permitted by this Thirteenth Supplemental Indenture, including, without limitation to facilitate the issuance and administration of the Notes; provided , however , that (i) compliance with this Thirteenth Supplemental Indenture as so amended would not result in Notes being transferred in violation of the Securities Act or any applicable securities law and (ii) such amendment does not materially and adversely affect the rights of Holders to transfer Notes.

Upon the request of the Issuer accompanied by a resolution of its board of directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Issuer and the Parent Guarantor in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Thirteenth Supplemental Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Thirteenth Supplemental Indenture or otherwise.

Section 9.02 With Consent of Holders of Notes .

Except as provided below in this Section 9.02, the Issuer, the Parent Guarantor and the Trustee may amend or supplement this Thirteenth Supplemental Indenture, the Guarantee and the Notes with the consent of the Holders of at least a majority in principal amount of the Notes (including Additional Notes, if any) then outstanding voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Thirteenth Supplemental Indenture, the Guarantee or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes (including Additional Notes, if any) voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Section 2.08 hereof and Section 2.09 hereof shall determine which Notes are considered to be “outstanding” for the purposes of this Section 9.02.

Upon the request of the Issuer accompanied by a resolution of its board of directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Issuer in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Thirteenth Supplemental Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture.

-47-

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

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

Without the consent of each affected Holder of Notes, an amendment or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

(1) change the stated maturity of the principal of, or installment of interest, if any, on, the Notes, or reduce the principal amount thereof or the interest thereon or any premium payable upon redemption thereof;

(2) change the currency in which the principal of (and premium, if any) or interest on such Notes are denominated or payable, or reduce the amount of the principal of a discount security that would be due and payable upon redemption thereof;

(3) adversely affect the right of repayment or repurchase, if any, at the option of the Holder after such obligation arises, or reduce the amount of, or postpone the date fixed for, any payment under any sinking fund or impair the right to institute suit for the enforcement of any payment on or after the stated maturity thereof (or, in the case of redemption, on or after the Redemption Date);

(4) reduce the percentage of Holders whose consent is required for modification or amendment of this Thirteenth Supplemental Indenture or for waiver of compliance with certain provisions of this Thirteenth Supplemental Indenture or certain defaults;

(5) modify the provisions that require Holder consent to modify or amend this Thirteenth Supplemental Indenture or that permit Holders to waive compliance with certain provisions of this Thirteenth Supplemental Indenture or certain defaults; or

(6) except as expressly permitted by this Thirteenth Supplemental Indenture, modify the Guarantee in any manner adverse to the Holders of the Notes.

Section 9.03 Compliance with Trust Indenture Act .

Every amendment or supplement to this Thirteenth Supplemental Indenture or the Notes shall be set forth in an amended or supplemental indenture that complies with the Trust Indenture Act as then in effect.

Section 9.04 Revocation and Effect of Consents .

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent

-48-

is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder; provided that any amendment or waiver that requires the consent of each affected Holder shall not become effective with respect to any non-consenting Holder.

The Issuer may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement, or waiver. If a record date is fixed, then, notwithstanding the preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only such Persons, shall be entitled to consent to such amendment, supplement, or waiver or to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date unless the consent of the requisite number of Holders has been obtained.

Section 9.05 Notation on or Exchange of Notes .

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuer in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver.

Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver.

Section 9.06 Trustee to Sign Amendments, etc .

The Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Issuer may not sign an amendment, supplement or waiver until the board of directors approves it. In executing any amendment, supplement or waiver, the Trustee shall be entitled to receive and (subject to Section 7.01 hereof) shall be fully protected in relying upon, in addition to the documents required by Section 12.04 hereof, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Thirteenth Supplemental Indenture and that such amendment, supplement or waiver is the legal, valid and binding obligation of the Issuer and the Parent Guarantor, enforceable against them in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof (including Section 9.03).

Section 9.07 Payment for Consent .

Neither the Issuer nor any Affiliate of the Issuer shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Thirteenth Supplemental Indenture or the Notes unless such consideration is offered to all Holders and is paid to all Holders that so consent, waive or agree to amend in the time frame set forth in solicitation documents relating to such consent, waiver or agreement.

ARTICLE 10

GUARANTEE

Section 10.01 Guarantee .

(a) The Parent Guarantor hereby unconditionally guarantees the punctual payment when due, whether at stated maturity, by acceleration or otherwise, of all of the monetary obligations of the Issuer under this Thirteenth Supplemental Indenture and the Notes, whether for principal or interest on the Notes, expenses, indemnification or otherwise (all such obligations of the Parent Guarantor being herein referred to as the “ Parent Guaranteed Obligations ”).

(b) It is the intention of the Parent Guarantor that the Guarantee not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to the Guarantee. To effectuate the foregoing intention, the amount guaranteed by the Parent Guarantor under the Guarantee shall be limited to the maximum amount as will, after giving effect to such maximum amount and all other contingent and fixed liabilities of the Parent Guarantor that are relevant under such laws, result in the obligations of the Parent Guarantor under the Guarantee not constituting a fraudulent transfer or conveyance.

(c) The Parent Guarantor guarantees that the Parent Guaranteed Obligations will be paid strictly in accordance with the terms of this Thirteenth Supplemental Indenture, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of Holders of the Notes with respect thereto. The liability of the Parent Guarantor under the Guarantee shall be absolute and unconditional irrespective of:

(i) any lack of validity, enforceability or genuineness of any provision of this Thirteenth Supplemental Indenture, the Notes or any other agreement or instrument relating thereto;

(ii) any change in the time, manner or place of payment of, or in any other term of, all or any of the Parent Guaranteed Obligations, or any other amendment or waiver of or any consent to departure from this Thirteenth Supplemental Indenture;

(iii) any exchange, release or non-perfection of any collateral, or any release or amendment or waiver of or consent to departure from any other guarantee, for all or any of the Parent Guaranteed Obligations; or

(iv) any other circumstance that might otherwise constitute a defense available to, or a discharge of, the Issuer or a guarantor.

(d) The Parent Guarantor covenants and agrees that its obligation to make payments of the Parent Guaranteed Obligations hereunder constitutes an unsecured obligation of the Parent Guarantor ranking pari passu with all existing and future senior unsecured indebtedness of the Parent Guarantor that is not subordinated in right of payment to the Guarantee.

(e) The Parent Guarantor hereby waives promptness, diligence, notice of acceptance and any other notice with respect to the Guarantee and any requirement that the Trustee, or the Holders of any Notes protect, secure, perfect or insure any security interest or lien or any property subject thereto or exhaust any right or take any action against the Issuer or any other Person or any collateral.

-50-

(f) The Parent Guarantor hereby irrevocably waives any claims or other rights that it may now or hereafter acquire against the Issuer that arise from the existence, payment, performance or enforcement of the Parent Guarantor’s obligations under the Guarantee or this Thirteenth Supplemental Indenture, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of the Trustee, or the Holders of any Notes against the Issuer or any collateral, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from the Issuer, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right. If any amount shall be paid to the Parent Guarantor in violation of the preceding sentence at any time prior to the cash payment in full of the Parent Guaranteed Obligations and all other amounts payable under the Guarantee, such amount shall be held in trust for the benefit of the Trustee and the Holders of any Notes and shall forthwith be paid to the Trustee, to be credited and applied to the Parent Guaranteed Obligations and all other amounts payable under the Guarantee, whether matured or unmatured, in accordance with the terms of this Thirteenth Supplemental Indenture and the Guarantee, or be held as collateral for any Parent Guarantor Obligations or other amounts payable under the Guarantee thereafter arising. The Parent Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Thirteenth Supplemental Indenture and the Guarantee and that the waiver set forth in this Section 10.01 is knowingly made in contemplation of such benefits.

(g) No failure on the part of the Trustee or any Holder of the Notes to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

(h) The Guarantee is a continuing guarantee and shall (a) subject to paragraph 10.01(i), remain in full force and effect until payment in full of the principal amount of all outstanding Notes (whether by payment at maturity, purchase, redemption, defeasance, retirement or other acquisition) and all other applicable Parent Guaranteed Obligations of the Parent Guarantor then due and owing, (b) be binding upon the Parent Guarantor, its successors and assigns, and (c) inure to the benefit of and be enforceable by the Trustee, any Holder of Notes, and by their respective successors, transferees, and assigns.

(i) The Parent Guarantor will automatically and unconditionally be released from all Parent Guaranteed Obligations, and the Guarantee shall thereupon terminate and be discharged and of no further force of effect, (i) upon any merger or consolidation of such Parent Guarantor with the Issuer, (ii) upon exercise by the Issuer of its Legal Defeasance option or Covenant Defeasance option in accordance with Article 8 hereof or the discharge of the Issuer’s obligations under this Thirteenth Supplemental Indenture, in accordance with the terms of this Thirteenth Supplemental Indenture, or (iii) upon payment in full of the aggregate principal amount of all Notes then outstanding and all other applicable Parent Guaranteed Obligations of the Parent Guarantor then due and owing.

Upon any such occurrence specified in this paragraph 10.01(i), the Trustee shall execute upon request by the Issuer, any documents reasonably required in order to evidence such release, discharge and termination in respect of the Guarantee. Neither the Issuer nor the Parent Guarantor shall be required to make a notation on the Notes to reflect the Guarantee or any such release, termination or discharge.

(j) The Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the Issuer for liquidation, reorganization, should the Issuer become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed

-51-

for all or any significant part of the Issuer’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes or Guarantee, whether as a “voidable preference,” “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment or any part thereof, is rescinded, reduced, restored or returned, the Notes shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

(k) The Parent Guarantor may amend the Guarantee at any time for any purpose without the consent of the Trustee or any Holder of the Notes; provided , however , that if such amendment adversely affects (a) the rights of the Trustee or (b) any Holder of the Notes, the prior written consent of the Trustee (in the case of (b), acting at the written direction of the Holders of more than 50% in aggregate principal amount of Notes) shall be required.

(2) (A) all Notes not theretofore delivered to the Trustee for cancellation have become due and payable by reason of the making of a notice of redemption or otherwise, shall become due and payable within one year or may 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 Issuer, and the Issuer or the Parent Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders of the Notes, cash in U.S. dollars, Government Securities, or a combination thereof, in such amounts as will be sufficient without consideration of any reinvestment of interest to pay and discharge the entire indebtedness on the Notes not theretofore delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption;

(B) no Default (other than that resulting from borrowing funds to be applied to make such deposit and any similar and simultaneous deposit relating to other Indebtedness and, in each case, the granting of Liens in connection therewith) with respect to this Thirteenth Supplemental Indenture or the Notes shall have occurred and be continuing on the date of such deposit or shall occur as a result of such deposit and such deposit will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Thirteenth Supplemental Indenture) to which the Issuer or the Parent Guarantor is a party or by which the Issuer is bound (other than that resulting from borrowing funds to be applied to make such deposit and any similar and simultaneous deposit relating to other Indebtedness and in each case, the granting of Liens in connection therewith);

If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuer’s and the Parent Guarantor’s obligations under this Thirteenth Supplemental Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01 hereof; provided that if the Issuer has made any payment of principal of, premium or interest on any Notes because of the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.
