For and in consideration of the premises stated herein, the parties hereto hereby agree as follows:

ARTICLE I

DEFINITIONS

Section 1.1 Certain Terms Defined in the Indenture.

For purposes of this First Supplemental Indenture, all capitalized terms used but not defined herein shall have the meanings ascribed to such terms in the Original Indenture, as amended and supplemented hereby.

Section 1.2 Definitions.

For all purposes of this First Supplemental Indenture:

“Acquired Indebtedness” means Indebtedness of a Person (1) existing at the time such Person is merged or consolidated with or into, or becomes a Consolidated Subsidiary of the Guarantor or the Company, or (2) assumed by the Guarantor, the Company or any of the Consolidated Subsidiaries in connection with the acquisition of assets from such Person. Acquired Indebtedness shall be deemed to be Incurred on the date the acquired Person is merged or consolidated with or into, or becomes a Consolidated Subsidiary or the date of the related acquisition, as the case may be.

“Comparable Treasury Issue” means the United States Treasury security or securities selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the notes that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the notes.

“Comparable Treasury Price” means, with respect to any redemption date, (1) the average of three Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest of five Reference Treasury Dealer Quotations obtained, or (2) if the Company obtains fewer than five such Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations obtained.

“Consolidated Net Income” means, for any period of time, the amount of net income, or loss, for the Guarantor, the Company and the Consolidated Subsidiaries for such period, excluding, without duplication, extraordinary items and the portion of net income, but not losses, for the Guarantor, the Company and the Consolidated Subsidiaries allocable to noncontrolling interests in unconsolidated Persons to the extent that cash dividends or distributions allocable to noncontrolling interests in unconsolidated Persons have not actually been received by the Guarantor, the Company or any of the Consolidated Subsidiaries, all determined in accordance with GAAP.

Indebtedness that is not Intercompany Indebtedness at the time of such issuance, transfer or sale, as the case may be.

“Indebtedness” means, without duplication, any indebtedness of the Guarantor, the Company or any Consolidated Subsidiary, whether or not contingent, in respect of: (a) borrowed money evidenced by bonds, notes, debentures or similar instruments whether or not such indebtedness is secured by any lien existing on property owned by the Guarantor, the Company or any Consolidated Subsidiary; (b) indebtedness for borrowed money of a Person other than the Guarantor, the Company or any Consolidated Subsidiary which is secured by any lien on property owned by the Guarantor, the Company or any Consolidated Subsidiary, to the extent of the lesser of (i) the amount of indebtedness so secured, and (ii) the fair market value of the property subject to such lien; (c) the reimbursement obligations, contingent or otherwise, in connection with any letters of credit actually issued or amounts representing the balance deferred and unpaid of the purchase price of any property or services, except any such balance that constitutes an accrued expense or trade payable; or (d) any lease of property by the Guarantor, the Company or any Consolidated Subsidiary as lessee which is reflected in the Consolidated Financial Statements as a capitalized lease in accordance with GAAP, to the extent, in the case of indebtedness under (a) through (c) above, that any such items (other than letters of credit) would appear as a liability in the Consolidated Financial Statements in accordance with GAAP.

For this purpose, such covenant defeasance means that, with respect to the Notes, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such Section or such other covenant, whether directly or indirectly, by reason of any reference elsewhere in the Indenture to any such Section or such other covenant or by reason of reference in any such Section or in any other document and such omission to comply shall not constitute a default or an Event of Default under Section 6.01(4) of the Indenture (as such Section 6.01(4) has been restated in Article III of this First Supplemental Indenture), but, except as specified above, the remainder of the Indenture with regard to the Notes shall be unaffected thereby.

(e) In the case of an election under Section 4.3, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Notes then outstanding will not recognize income, gain or loss for Federal income tax purposes as a result of such covenant defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred.

The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 4.4 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the Notes then outstanding.

Anything in this Article IV to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon request of the Company any money or U.S. Government Obligations (or other property and any proceeds therefrom) held by it as provided in Section 4.4 which, in the opinion of a nationally recognized firm of independent public accountants or investment bank expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect a defeasance or covenant defeasance, as applicable, in accordance with this Article IV.
