EACH PURCHASER OF THIS SECURITY IS HEREBY NOTIFIED THAT THE SELLER OF THIS SECURITY MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER.

THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) THIS SECURITY MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I) IN THE UNITED STATES TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (II) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH RULE 904 UNDER THE SECURITIES ACT, (III) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE), (IV) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (BASED UPON AN OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY IF THE COMPANY SO REQUESTS) OR (V) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH OF CASES (I) THROUGH (V) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS SECURITY FROM IT OF THE RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE.”

Each Definitive Security shall bear the following legend on the face thereof:

“IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE SECURITY REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER INFORMATION AS SUCH TRANSFER AGENT MAY

REASONABLY REQUIRE TO CONFIRM THAT THE TRANSFER COMPLIES WITH THE FOREGOING RESTRICTIONS.”

(b) Upon any sale or transfer of a Restricted Security pursuant to Rule 144 under the Securities Act, the Depositary shall, subject to approval by the Company and the provisions of Section 3.5 of the Original Indenture, permit the Holder thereof to request the issuance of a global Senior Note that does not bear one or more of the legends set forth above and rescind any restrictions on the transfer of such Restricted Security, if the sale or exchange was made in reliance on Rule 144 and the Holder certifies to that effect in writing to the Depositary.

(c) Upon a sale or transfer after the expiration of the Distribution Compliance Period of any Senior Notes acquired pursuant to Regulation S, all requirements that such Senior Notes bear the Restricted Legend shall cease to apply (but requirements requiring such Senior Notes to be in global form and bear the global legend in Section 2.8 shall continue to apply).

Section 2.7. Restrictions on Transfer and Exchange of Senior Notes.

(a) All 5.875% Senior Notes due 2016 issued upon any registration of transfer or exchange of 5.875% Senior Notes due 2016 shall be valid obligations of the Company, evidencing the same interest therein, and entitled to the same benefits under the Original Indenture and this Second Supplemental Indenture, as the 5.875% Senior Notes due 2016 surrendered upon such registration of transfer or exchange.

A Holder may transfer a 5.875% Senior Note due 2016, or request that a 5.875% Senior Note due 2016 be exchanged for 5.875% Senior Notes due 2016 in authorized denominations and in an aggregate principal amount equal to the principal amount of such 5.875% Senior Note due 2016 surrendered for exchange of other authorized denominations, by surrender of such 5.875% Senior Note due 2016 to the Trustee with the form of transfer notice thereon duly completed and executed, and otherwise complying with the terms of the Original Indenture and this Second Supplemental Indenture, including providing evidence of compliance with any restrictions on transfer, in form satisfactory to the Company, the Trustee and the Security Registrar. No such transfer shall be effected until, and such transferee shall succeed to the rights of a Holder only upon, final acceptance and registration of the transfer by the Security Registrar in the Register. Prior to the registration of any transfer of a 5.875% Senior Note due 2016 by a Holder as provided herein, the Company, the Security Registrar, the Paying Agent and the Trustee shall deem and treat the person in whose name the Security is registered on the Register as the absolute owner and holder thereof for the purpose of receiving payment of all amounts payable with respect to such Security and for all other purposes, and none of the Company, the Security Registrar, the Paying Agent or the Trustee shall be affected by any notice to the contrary. Furthermore, the Depositary shall, by acceptance of a Global Security, agree that transfers of beneficial interests in such Global Security may be effected only through a book-entry system maintained by the Depositary (or its agent) and that ownership of a beneficial interest in the 5.875% Senior Notes due 2016 shall be required to be reflected in a book-entry.

Senior Notes due 2016 surrendered for exchange, the Security Registrar shall register the transfer or make the exchange as requested if its requirements for such transactions are met.

To permit registrations of transfers and exchanges in accordance with the terms, conditions and restrictions hereof, the Company shall execute, and the Trustee shall authenticate, 5.875% Senior Notes due 2016 at the Security Registrar’s request. No service charge shall be made to a Holder for any registration of transfer or exchange of 5.875% Senior Notes due 2016, but the Company may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of 5.875% Senior Notes due 2016. All 5.875% Senior Notes due 2016 surrendered for registration of transfer or exchange shall be cancelled by the Trustee in accordance with its then customary procedures.

(b) All 6.375% Senior Notes due 2036 issued upon any registration of transfer or exchange of 6.375% Senior Notes due 2036 shall be valid obligations of the Company, evidencing the same interest therein, and entitled to the same benefits under the Original Indenture and this Second Supplemental Indenture, as the 6.375% Senior Notes due 2036 surrendered upon such registration of transfer or exchange.

A Holder may transfer a 6.375% Senior Note due 2036, or request that a 6.375% Senior Note due 2036 be exchanged for 6.375% Senior Notes due 2036 in authorized denominations and in an aggregate principal amount equal to the principal amount of such 6.375% Senior Note due 2036 surrendered for exchange of other authorized denominations, by surrender of such 6.375% Senior Note due 2036 to the Trustee with the form of transfer notice thereon duly completed and executed, and otherwise complying with the terms of the Original Indenture and this Second Supplemental Indenture, including providing evidence of compliance with any restrictions on transfer, in form satisfactory to the Company, the Trustee and the Security Registrar. No such transfer shall be effected until, and such transferee shall succeed to the rights of a Holder only upon, final acceptance and registration of the transfer by the Security Registrar in the Register. Prior to the registration of any transfer of a 6.375% Senior Note due 2036 by a Holder as provided herein, the Company, the Security Registrar, the Paying Agent and the Trustee shall deem and treat the person in whose name the Security is registered on the Register as the absolute owner and holder thereof for the purpose of receiving payment of all amounts payable with respect to such Security and for all other purposes, and none of the Company, the Security Registrar, the Paying Agent or the Trustee shall be affected by any notice to the contrary. Furthermore, the Depositary shall, by acceptance of a Global Security, agree that transfers of beneficial interests in such Global Security may be effected only through a book-entry system maintained by the Depositary (or its agent) and that ownership of a beneficial interest in the 6.375% Senior Notes due 2036 shall be required to be reflected in a book-entry. When 6.375% Senior Notes due 2036 are presented to the Security Registrar with a request to register the transfer thereof or to exchange them for other authorized denominations of a 6.375% Senior Note due 2036 in a principal amount equal to the aggregate principal amount of 6.375% Senior Notes due 2036 surrendered for exchange, the Security Registrar shall register the transfer or make the exchange as requested if its requirements for such transactions are met.

Section 2.8 Book-Entry Provisions for Restricted Global Securities and Regulation S Global Securities.

(a) Members of, or participants in, DTC (“Agent Members”) shall have no rights under the Original Indenture, this Second Supplemental Indenture and the Senior Notes with respect to any Global Security held on their behalf by DTC, or the Trustee, as its custodian, and DTC may be treated by the Company, the Trustee and any agent of the Trustee as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Trustee from giving effect to any written certification, proxy or other authorization furnished by DTC or shall impair, as between DTC and its Agent Members, the operation of customary practices governing the exercise of the rights of a holder of any Security. Upon the issuance of any Global Security, the Security Registrar or its duly appointed agent shall record DTC as the registered holder of such Global Security.

(b) Transfers of any Global Security shall be limited to transfers of such Restricted Global Security or Regulation S Global Security in whole, but not in part, to DTC. Beneficial interests in the Restricted Global Security and any Regulation S Global Security may be transferred in accordance with the rules and procedures of DTC and the provisions of Section 2.9. Beneficial interests in a Restricted Global Security or a Regulation S Global Security shall be delivered to all beneficial owners thereof in the form of Rule 144A Definitive Securities (“Rule 144A Definitive Securities”) or Regulation S Definitive Securities (“Regulation S Definitive Securities”), as the case may be, if (i) DTC notifies the Trustee that it is unwilling or unable to continue as depositary for such Restricted Global Security or Regulation S Global Security, as the case may be, and a successor depositary is not appointed by the Trustee within 90 days of such notice and (ii) after the occurrence and during the continuance of an Event of Default, owners of beneficial interests in a Global Security with a principal amount aggregating not less than a majority of the outstanding principal amount of the Global Security advise the Trustee, the Company and DTC through Agent Members in writing that the continuation of a book-entry system through DTC is no longer in their best interests.

(d) Any beneficial interest in one of the Global Securities that is transferred to a Person who takes delivery in the form of an interest in another Global Security will, upon such transfer, cease to be an interest in such Global Security and become an interest in the other Global Security and, accordingly, will thereafter be subject to all transfer restrictions, if any, and other procedures applicable to beneficial interests in such other Global Security for as long as it remains such an interest.

(e) In connection with the transfer of an entire Restricted Global Security or an entire Regulation S Global Security to the beneficial owners thereof pursuant to paragraph (b) of this Section 2.8, such Restricted Global Security or Regulation S Global Security, as the case may be,

shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate, to each beneficial owner identified by DTC in exchange for its beneficial interest in such Restricted Global Security or Regulation S Global Security, as the case may be, an equal aggregate principal amount of Rule 144A Definitive Securities or Regulation S Definitive Securities, as the case may be, of authorized denominations. None of the Company, the Security Registrar, the Paying Agent or the Trustee shall be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such registration instructions. Upon the issuance of Rule 144A Definitive Securities or Regulation S Definitive Securities, as the case may be, the Company and the Trustee shall recognize the Person in whose name the Rule 144A Definitive Securities or Regulation S Definitive Securities, as the case may be, are registered in the Register as Holders hereunder.

(f) Any Rule 144A Definitive Securities or Regulation S Definitive Securities, as the case may be, delivered in exchange for an interest in the Restricted Global Security pursuant to paragraph (b) of this Section 2.8 shall, except as otherwise provided by paragraph (d) of Section 2.9, bear the Restricted Legend.

(g) Prior to the expiration of the Distribution Compliance Period, any interests in a Regulation S Global Security issued in definitive, fully registered form without interests coupons (“Regulation S Definitive Security”) delivered in exchange for an interest in a Regulation S Global Security pursuant to paragraph (b) of this Section 2.8 shall bear the Restricted Legend.

(h) The registered holder of any Restricted Global Security or Regulation S Global Security may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under the Original Indenture or this Second Supplemental Indenture or the Securities.

(i) Neither the Company nor the Trustee shall be liable if the Trustee or the Company is unable to locate a qualified successor clearing agency.

Section 2.9 Special Transfer Provisions.

The following provisions shall also apply to the Senior Notes:

(a) Transfers to QIBs. The following provisions shall apply with respect to the registration of any proposed transfer of a Senior Note required to bear the Restricted Legend to a QIB (excluding Non-U.S. Persons):

(i) If the Senior Note to be transferred consists of an interest in any Regulation S Global Security during the Distribution Compliance Period, the Security Registrar shall register the transfer if such transfer is being made by a proposed transferor who has checked the box provided for on the form of Senior Note stating, or has otherwise advised the Company, the Trustee and the Security Registrar in writing, that the sale has been made in compliance with the provisions of Rule 144A to a transferee who has signed the certification provided for on the form of Senior Note stating, or has otherwise advised the Company, the Trustee and the Security Registrar in writing, that it

is purchasing the Senior Note for its own account or an account with respect to which it exercises sole investment discretion and that it, or the Person on whose behalf it is acting with respect to any such account, is a QIB within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Company as it has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A.

(ii) Upon receipt by the Security Registrar of the documents required by clause (i) above and instructions given in accordance with DTC’s and the Security Registrar’s procedures therefor, the Security Registrar shall reflect on its books and records the date of such transfer and an increase in the principal amount of a Restricted Global Security in an amount equal to the principal amount of the interests in such Regulation S Global Security and the Trustee shall decrease the amount of such Regulation S Global Security so transferred.

(b) Transfers of Interests in the Regulation S Global Security.

(i) After the expiration of the Distribution Compliance Period, the Security Registrar shall register any transfer of interests in any Regulation S Global Security without requiring any additional certification.

(ii) Until the expiration of the Distribution Compliance Period, interests in the Regulation S Global Security may only be sold, pledged or transferred through Euroclear S.A./N.V. or Clearstream Banking, société anonyme (as indirect participants in the Depositary) or Agent Members acting for and on behalf of Euroclear and Clearstream only (x) for interests in a Regulation S Global Security and then only upon certification in form reasonably satisfactory to the Trustee that interests in such Regulation S Global Security are owned by either Non-U.S. Persons or U.S. Persons who purchased such interests in a transaction that did not require registration under the Securities Act or (y) for interests in the Restricted Global Security or if the transferor first delivers to the Trustee a written transfer notice to the effect that the Securities are being transferred to a person (A) who the transferor reasonably believes to be a QIB; (B) purchasing for its own account or the account of a QIB in a transaction meeting the requirements of Rule 144A; and (C) in accordance with all applicable securities laws of the states of the United States and other jurisdictions.

(c) Transfers to Non-U.S. Persons at Any Time. The following provisions shall apply with respect to any registration of any transfer of a Senior Note to a Non-U.S. Person:

(i) Prior to the expiration of the Distribution Compliance Period, the Security Registrar shall register any proposed transfer of a Senior Note to a Non-U.S. Person upon receipt of a certificate substantially in the form set forth as Exhibit C or Exhibit D, as applicable, hereto from the proposed transferor.

(ii) After the expiration of the Distribution Compliance Period, the Security Registrar shall register any proposed transfer to any Non-U.S. Person if the Senior Note to be transferred is an interest in a Restricted Global Security, upon receipt of a certificate substantially in the form of Exhibit C or Exhibit D, as applicable, from the proposed transferor. The Security Registrar shall promptly send a copy of such certificate to the Company.

(iii) Upon receipt by the Security Registrar of (x) the documents, if any, required by clause (ii) and (y) instructions in accordance with DTC’s and the Security Registrar’s procedures, the Security Registrar shall reflect on its books and records the date of such transfer and a decrease in the principal amount of such Restricted Global Security in an amount equal to the principal amount of the beneficial interest in such Restricted Global Security to be transferred, and, upon receipt by the Security Registrar of instructions given in accordance with DTC’s and the Security Registrar’s procedures, the Security Registrar shall reflect on its books and records the date and an increase in the principal amount of the Regulation S Global Security in an amount equal to the principal amount of the Restricted Global Security to be transferred, and the Trustee shall decrease the amount of such Restricted Global Security.

(d) Restricted Legend. Upon the transfer, exchange or replacement of Senior Notes not bearing the Restricted Legend, the Security Registrar shall deliver Senior Notes that do not bear the Restricted Legend. Upon the transfer, exchange or replacement of Senior Notes bearing the Restricted Legend, the Security Registrar shall deliver only Senior Notes that bear the Restricted Legend unless either (i) the circumstances contemplated by paragraph (c)(ii) of this Section 2.9 exist or (ii) there is delivered to the Security Registrar an opinion of counsel to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act.

(e) General. By acceptance of any Senior Note bearing the Restricted Legend, each Holder of such Senior Note acknowledges the restrictions on transfer of such Senior Note set forth in such Restricted Legend and otherwise in this Second Supplemental Indenture and agrees that it will transfer such Senior Note only as provided in such Restricted Legend and otherwise in this Second Supplemental Indenture. In connection with any transfer of Senior Notes, each Holder agrees by its acceptance of the Senior Notes to furnish the Security Registrar or the Trustee such certifications, legal opinions or other information as either of them may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or a transaction not subject to, the registration requirements of the Securities Act and in accordance with the terms and provisions of this Article 2; provided that the Security Registrar shall not be required to determine the sufficiency of any such certifications, legal opinions or other information.

Until such time as no Senior Notes remain Outstanding, the Security Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 2.8 or this Section 2.9. The Trustee, if not the Security Registrar at such time, shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Security Registrar.

In the event that any Global Security or any portion thereof is exchanged for Definitive Securities, such other Definitive Securities may be exchanged (by transfer or otherwise) for Definitive Securities or for beneficial interests in a Global Security (if any is then outstanding) only in accordance with procedures substantially consistent with this Article Two (including any certification requirements) and applicable procedures adopted by the Company and the Trustee.

Until Definitive Securities are ready for delivery, the Company may use temporary Securities. Temporary Securities shall be substantially in the form of Definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall deliver Definitive Securities in exchange for temporary Securities.

The Company may issue some or all of the Securities in temporary or permanent global form. The Company may issue a Global Security only to the Depositary. A Depositary may transfer a Global Security only to its nominee or to a successor Depositary. A Global Security shall represent the amount of Senior Notes specified in the Global Security. A Global Security may have variations that the Depositary requires or that the Company considers appropriate for such a security.

Beneficial owners of part or all of a Global Security are subject to the rules of the Depository as in effect from time to time.

The Company, the Trustee and their agents shall not be responsible for any acts or omissions of a Depositary, for any Depositary records of beneficial ownership interests or for any transactions between or among the Depositary, Agent Members and beneficial owners.

The Company at any time may deliver Senior Notes to the Trustee for cancellation. The Paying Agent, if not the Trustee, shall forward to the Trustee any Senior Notes surrendered to them for payment or conversion. The Trustee shall cancel all Senior Notes surrendered for registration of transfer, exchange, payment or cancellation and shall dispose of cancelled Senior Notes according to its then customary practices. The Company may not issue new Senior Notes to replace Senior Notes that it has paid or which have been delivered to the Trustee for cancellation.

Section 2.10. Restrictions on Liens. The covenant provided by Section 10.9 of the Original Indenture shall be applicable to the Senior Notes; provided, however, that the dollar amount set forth in paragraph (b) of Section 10.9 shall be $100,000,000 with respect to the Senior Notes.

Section 2.11. Restrictions on Sale and Leaseback Transactions. The covenant provided by Section 10.10 of the Original Indenture shall be applicable to the Senior Notes.

Section 2.12. Limitation on Incurrence of Debt. The covenant provided by Section 10.8 of the Original Indenture shall not be applicable to the Senior Notes.

In the event of a partial redemption of the Senior Notes, the Company will issue new Senior Notes for the unredeemed portion in the name of each Holder of the partially redeemed Senior Notes.

If less than all of the Senior Notes are to be redeemed, the Senior Notes will be redeemed by lot, pro rata by the Trustee or by such method of selection as the Trustee shall deem fair and appropriate and which may, in any case, provide for the selection for redemption of Senior Notes and portions of Senior Notes in amounts of $2,000 or any integral multiples of $1,000 in excess thereof from the outstanding Senior Notes, in accordance with Section 11.3 of the Original Indenture.

This Senior Note may be redeemed in accordance with the procedures set forth in the Indenture on not less than 30 nor more than 60 days’ notice given as provided in the Indenture, as a whole or in part, at any time at the option of the Company, at a redemption price equal to the greater of (i) 100% of the principal amount of the Senior Notes being redeemed and (ii) as determined by an Independent Investment Banker, the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest accrued as of the redemption date) discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus, in each case, accrued and unpaid interest thereon to, but excluding, the redemption date (the “Make-Whole Price”); provided, however, that installments of interest on the Senior Notes that are due and payable on an interest payment date falling on or prior to the relevant redemption date will be payable to the holders of such Senior Notes, registered as such at the close of business on the relevant record date according to the terms and provisions of the Indenture.
