C.    Capitalized terms used herein shall have the respective meanings ascribed thereto in the Note Purchase Agreement unless herein defined or the context shall otherwise require.

D.    All requirements of law have been fully complied with and all other acts and things necessary to make this Amendment a valid, legal and binding instrument according to its terms for the purposes herein expressed have been done or performed.

NOW, THEREFORE, the Obligors and the Noteholders, in consideration of good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, do hereby agree as follows:

SECTION 1. AMENDMENTS TO NOTE PURCHASE AGREEMENT.

Subject to the terms and conditions set forth herein, the Note Purchase Agreement (exclusive of Schedules thereto) is amended as follows:

(a)    Section 9.11 of the Note Purchase Agreement is hereby amended by:

(i)    amending and restating the second parenthetical in clause (a)(iii) of Section 9.11 to read as follows:

(any such provision and any Restricted Payment Provisions described in clause (e) below, in each case, together with all definitions and interpretive provisions from such Credit Agreement to the extent used in relation thereto, a “Most Favorable Covenant”)

and

(ii)    adding a new clause (e) to follow clause (d), which shall read as follows:

(e) In addition to the foregoing, the Obligors agree that the “Restricted Payments” covenants contained in each of the Credit Agreements are hereby incorporated by reference into this Agreement, mutatis mutandis, as if set forth in full herein, effective as of the Fourth Amendment Effective Date, and such Restricted Payments covenants shall be deemed to constitute Incorporated Covenants for purposes of this Section 9.11. Upon the request of any holder of a Note, the Obligors shall enter into any additional agreement or amendment to this Agreement reasonably requested by such holder to further evidence the foregoing. In addition, the Most Favorable Covenants under this Section 9.11 shall include any covenant (whether constituting a covenant or event of default) of an Obligor contained in any Credit Agreement from and after the Fourth Amendment Effective Date that expressly and directly limits dividends or other restricted payments (collectively, “Restricted Payment Provisions”), and all rights and obligations set forth herein with respect to Most Favorable Covenants shall apply equally thereto. For informational purposes only, the Restricted Payments covenant contained in the Credit Agreements as of the Fourth Amendment

Effective Date is set forth on Exhibit A to the Fourth Amendment to this Agreement.

(b)    Section 10.7 of the Note Purchase Agreement is hereby amended and restated in its entirety to read as follows:

Section 10.7.    Leverage Ratio. The Parent Guarantor shall not permit the ratio (the “Leverage Ratio”) of (i) all Adjusted Indebtedness of the Parent Guarantor and its Subsidiaries as of any date of determination (but excluding Excluded JV Indebtedness) to (ii) EBITDA for the most recently-ended period of four-fiscal quarters for which financial statements were required to be delivered to exceed the lesser of (a) 3.00:1.0 and (b) the level required to be maintained under a similar leverage covenant contained in any Credit Agreement for such applicable fiscal period. For purposes of this Section, if during the period of calculation any Obligor or any Subsidiary shall have acquired or disposed of any Person or acquired or disposed of all or substantially all of the operating assets of any Person, EBITDA for such period shall be calculated after giving pro forma effect thereto as if such transaction occurred on the first day of such period.

The Leverage Ratio shall be calculated as of the last day of each fiscal quarter based upon (A) for Adjusted Indebtedness, Adjusted Indebtedness (but excluding Excluded JV Indebtedness) as of the last day of each such fiscal quarter and (B) for EBITDA, the actual amount for the four quarter period ending on such day, calculated, with respect to acquisitions and disposals, if any, as provided in the preceding paragraph.

SECTION 2. AMENDMENTS TO DEFINED TERMS.

(a)    Schedule B to the Note Purchase Agreement is hereby amended by amending and restating the following existing definitions to read as follows:
