(i) Liens on property of, or shares of stock or Debt issued by, any Subsidiary existing at the time such Subsidiary becomes a Restricted Subsidiary; provided, that such Lien shall not have been incurred in connection with the transfer by the Company or a Restricted Subsidiary of a Principal Property to such Subsidiary unless the Company, within 180 days of the effective date of such transfer, applies or causes a Restricted Subsidiary to apply an amount equal to the fair value, as determined by the Board of Directors, of such Principal Property at the time of such transfer, to the retirement of Senior Notes or other Debt of the Company (other than Debt subordinated to the Senior Notes), or Debt of any Restricted Subsidiary (other than Debt owed to the Company or any Restricted Subsidiary), having a stated maturity (x) more than 12 months from the date of such application or (y) which is extendable at the option of the obligor thereon to a date more than 12 months from the date of such application;

(iv) Liens which secure Debt owed by a Restricted Subsidiary to the Company or to another Restricted Subsidiary or by the Company to a Restricted Subsidiary so long as the Debt is held by the Company or a Restricted Subsidiary;

(viii) Liens created or assumed by a Subsidiary on oil, gas, coal or other mineral property, owned or leased by a Subsidiary, to secure Debt of such Subsidiary for the purpose of developing such property, including any interest of the character commonly referred to as a “production payment”; provided, however, that neither the Company nor any Subsidiary shall assume or guarantee such Debt or otherwise be liable in respect thereof; and

(ix) any extension, renewal or replacement (or successive extensions, renewals or replacements), in whole or in part, of any Lien referred to in the foregoing clauses (i) to (viii), inclusive, or of any Debt secured thereby; provided, that such extension, renewal or replacement Lien shall be limited to all or any part of the same property that secured the Lien extended, renewed or replaced (plus any improvements and construction on such property) and shall secure no larger amount of Debt than that which had been so secured at the time of such extension, renewal or replacement and, in the case of clause (iv), that the Debt being secured thereby is being secured for the same type of Person as the Debt being replaced.

Section 2.10. Limitation on Sale and Leaseback Transactions. The Company shall not, and shall not permit any Restricted Subsidiary to, enter into any arrangement after March 18, 2008 with any bank, insurance company or other lender or investor (other than the Company or another Restricted Subsidiary) providing for the leasing as lessee by the Company or a Restricted Subsidiary of any Principal Property (except a lease for a term not to exceed three years by the end of which term it is intended that the use of such Principal Property by the lessee will be discontinued and a lease which secures or relates to industrial revenue or pollution control bonds or similar financing), which was or is owned by the Company or a Restricted Subsidiary and which has been or is to be sold or transferred by the Company or a Restricted Subsidiary to such Person, more than 180 days after the completion of construction and commencement of full operation of such property by the Company or such Restricted Subsidiary, to such lender or investor or to any Person to whom funds have been or are to be advanced by such lender or investor on the security of such Principal Property (herein called a “Sale and Leaseback Transaction”) unless:

(a) the Company or such Restricted Subsidiary would, at the time of entering into such arrangement, be entitled pursuant to clauses (i) through (ix) of subsection (a) of Section 2.9, without equally and ratably securing the Senior Notes, to issue, assume or guarantee Debt secured by a Lien on such Principal Property in the amount of the Attributable Debt arising from such Sale and Leaseback Transaction; or

(b) the Attributable Debt of the Company and its Restricted Subsidiaries in respect of such Sale and Leaseback Transaction and all other Sale and Leaseback Transactions entered into after the date of this Supplemental Indenture (other than such Sale and Leaseback Transactions as are permitted by subsection (a) or (c) of this Section 2.10), plus the aggregate principal amount of Debt secured by Liens on Principal Properties then outstanding (not including any such Debt secured by Liens described in clauses (i) through (ix) of subsection (a) of Section 2.9) which do not equally and ratably secure the Senior Notes, would not exceed 10% of Consolidated Net Tangible Assets; or

(c) the Company, within 180 days after any such sale or transfer, applies or causes a Restricted Subsidiary to apply an amount equal to the greater of the net proceeds of such sale or transfer or the fair value, as determined by the Board of Directors, of the Principal Property so sold and leased back at the time of entering into such Sale and Leaseback Transaction to the retirement of Senior Notes or other Debt of the Company (other than Debt subordinated to the Senior Notes), or Debt of any Restricted Subsidiary (other than Debt owed to the Company or any Restricted Subsidiary), having a stated maturity (i) more than 12 months from the date of such application or (ii) which is extendable at the option of the obligor thereon to a date more than 12 months from the date of such application; provided, that the amount to be so applied shall be reduced by (x) the principal amount of Senior Notes delivered to the Trustee for retirement and cancellation within 180 days after such sale or transfer, and (y) the principal amount of any such Debt of the Company or a Restricted Subsidiary other than Senior Notes voluntarily retired by the Company or a Restricted Subsidiary within 180 days after such sale or transfer. Notwithstanding the foregoing, no retirement referred to in this subdivision (c) may be effected by payment at Maturity.

Notwithstanding the foregoing, where the Company or any Restricted Subsidiary is the lessee in any Sale and Leaseback Transaction, Attributable Debt shall not include any Debt resulting from the guarantee by the Company or any other Restricted Subsidiary of the lessee’s obligation thereunder.

Section 2.11. Merger, Consolidation and Sale of Assets. In addition to the covenants provided in Section 6.04 of the Base Indenture, the Company will not consolidate or merge with or into any other entity, or sell other than for cash or lease its assets substantially as an entirety to another entity, or purchase the assets of another entity substantially as an entirety, if, as a result of any such consolidation, merger, sale, lease or purchase, properties or assets of the Company would become subject to a lien which would not be permitted by the Indenture, unless the Company or such successor Person, as the case may be, takes such steps as are necessary to effectively secure the Senior Notes equally and ratably with (or prior to) all indebtedness secured thereby.

Section 2.12. Events of Default. The term “Event of Default” with respect to the Senior Notes shall mean

(c) the failure of the Company, subject to the provisions of Section 6.06 of the Base Indenture, to perform any covenants or agreements contained in the Indenture (other than a covenant or agreement which has been expressly included in the Indenture solely for the benefit of a series of Securities other than the Senior Notes and other than a covenant or agreement a default in the performance of which is specifically addressed elsewhere in this

Section 2.12), which failure shall not have been remedied, or without provision deemed to be adequate for the remedying thereof having been made, for a period of 90 days after written notice shall have been given to the Company by the Trustee or shall have been given to the Company and the Trustee by Holders of 25% or more in aggregate principal amount of the Senior Notes then Outstanding, specifying such failure, requiring the Company to remedy the same and stating that such notice is a “Notice of Default” hereunder;

(e) the entry by a court having jurisdiction in the premises of a decree or order for relief in respect of the Company in an involuntary case under the federal bankruptcy laws, as now or hereafter constituted, or any other applicable federal or state bankruptcy, insolvency or other similar law now or hereafter in effect, or appointing a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of the Company or of substantially all the property of the Company or ordering the winding-up or liquidation of its affairs and such decree or order shall remain unstayed and in effect for a period of 90 consecutive days; or

provided, however, that no event described in clause (c) or (d) above shall constitute an Event of Default hereunder until a Responsible Officer assigned to and working in the Trustee’s corporate trust department has actual knowledge thereof or until a written notice of any such event is received by the Trustee at the Corporate Trust Office, and such notice refers to the facts underlying such event, the Senior Notes generally, the Company and the Indenture.

Section 2.13. Appointment of Agents. The Trustee will initially be the Security Registrar and Paying Agent for the Senior Notes.

Section 2.14. Defeasance upon Deposit of Moneys or U.S. Government Obligations. At the Company’s option, either (a) the Company shall be deemed to have been Discharged from its obligations with respect to the Senior Notes on the first day after the applicable conditions set forth in Section 12.03 of the Base Indenture have been satisfied or (b) the Company shall cease to be under any obligation to comply with any term, provision or condition set forth in Section 6.04 of the Base Indenture and Sections 2.9, 2.10 and 2.11 with respect to the Senior Notes at any time after the applicable conditions set forth in Section 12.03 have been satisfied.

This Security is one of the series designated on the face hereof, initially limited in aggregate principal amount to $500,000,000.

Optional Redemption. The Securities of this series are subject to redemption at the Company’s option, at any time and from time to time, in whole or in part, at a Redemption Price equal to the greater of (i) 100% of the principal amount to be redeemed plus accrued and unpaid interest thereon to the Redemption Date, and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities to be redeemed (exclusive of interest accrued to the Redemption Date) discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30 day months) at the applicable Treasury Rate (as defined below) plus 50 basis points plus accrued and unpaid interest on the principal amount being redeemed to the Redemption Date.

For purposes of determining the optional redemption price, the following definitions are applicable:

“Treasury Rate” means, with respect to any Redemption Date for the Securities, the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that Redemption Date.

The Treasury Rate will be calculated on the third business day preceding the Redemption Date.

“Comparable Treasury Issue” means the U.S. Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term (“remaining life”) of the Securities that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining terms of the Securities.

“Comparable Treasury Price” means, with respect to any Redemption Date:

(a) the average of four Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or

(b) if the Independent Investment Banker is unable to obtain at least four such Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations obtained by the Independent Investment Banker.

“Independent Investment Banker” means Banc of America Securities LLC, Citigroup Global Markets Inc., X.X. Xxxxxx Securities, Inc. or Xxxxxx Brothers Inc., as specified by the Company, or if these firms are unwilling or unable to select the applicable Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Company.

“Reference Treasury Dealer” means Banc of America Securities LLC, Citigroup Global Markets Inc., X.X. Xxxxxx Securities, Inc. or Xxxxxx Brothers Inc., (and their respective successors), provided however, that if any of the foregoing shall cease to be a primary U.S. government securities dealer (a “Primary Treasury Dealer”), the Company will substitute therefor another Primary Treasury Dealer.

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

Notice of any redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each registered Holder of the Securities to be redeemed. Unless the Company defaults in payment of the redemption price, on and after the Redemption Date, interest will cease to accrue on the Securities or portions of the Securities called for redemption. If fewer than all of the Securities are to be redeemed, the Trustee will select, not more than 60 days prior to the Redemption Date, the particular Securities or portions thereof for redemption from the outstanding Securities not previously called by such method as the Trustee deems fair and appropriate.

Except as set forth above, the Securities will not be redeemable by the Company prior to maturity and will not be entitled to the benefit of any sinking fund.

Defaults and Remedies. If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

Amendment, Modification and Waiver. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

Restrictive Covenants. The Indenture does not limit unsecured debt of the Company or any of its Subsidiaries. It does limit certain mortgages, liens and sale-leaseback transactions. The limitations are subject to a number of important qualifications and exceptions. Once a year the Company must report to the Trustee on compliance with the limitations.

Denominations, Transfer and Exchange. The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and in integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registerable in the Security Register, upon surrender of this Security for registration of transfer at the Registrar accompanied by a written request for transfer in form satisfactory to the Company and the Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Persons Deemed Owners. Prior to due presentment of this 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 this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

Miscellaneous. The Indenture and this Security shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflicts of law rules of said State.

All terms used in this Security and not defined herein shall have the meanings assigned to them in the Indenture.
