Changes in Covenants when Notes Rated Investment Grade.

(a) If, on any date, following the Notes Issue Date:

(1) the Notes receive at least two Investment Grade Issue Ratings; and

(2) no Default or Event of Default shall have occurred and be continuing,

then, beginning on that date and continuing at all times thereafter regardless of any subsequent changes in the rating of the Notes, the covenants set forth in Sections 4.15, 4.25, 4.30, and clause (d) of Section 5.01 will no longer be applicable to the Notes.

(b) If, on any date following the date on which (1) the Company satisfies the conditions in clauses (1) and (2) of Section 4.33(a) and (2) Parent (or any successor entity thereto) has a rating from all Acceptable Rating Agencies that rate both Parent (or any successor entity thereto) and the Company that is equivalent to or better than the Company’s rating from all Acceptable Rating Agencies that rate Parent (or any successor entity thereto) and the Company, then the covenant set forth in Section 4.10 will no longer be applicable to the Notes, beginning on such date and continuing until the Reversion Date (as defined below).

If, on any date, Parent (or any successor entity thereto) no longer has a rating from all Acceptable Rating Agencies that rate both Parent (or any successor entity thereto) and the Company that is equivalent to or better than the Company’s rating from all Acceptable Rating Agencies that rate Parent (or any successor entity thereto) and the Company, then on such date (the “Reversion Date”) the covenant set forth in Section 4.10 will be reinstated as if such covenant had never been suspended and will be applicable unless and until the conditions in the preceding paragraph of this clause (b) are satisfied. No Default, Event of Default or breach of any kind shall be deemed to exist under this Indenture or the Notes with respect to the covenant set forth in Section 4.10 and neither the Company nor any of its Subsidiaries shall bear any liability for, any actions taken or events occurring during the Suspension Period (as defined below), or any actions taken at any time pursuant to any contractual obligation arising prior to the Reversion Date, regardless of whether such actions or events would have been permitted if the covenant set forth in Section 4.10 remained in effect during such period. The period of time between the date of the suspension of the covenant set forth in Section 4.10 and the Reversion Date is referred to as the “Suspension Period.”

(c) In addition, on any date following the date on which the Company satisfies the conditions in clauses (1) and (2) of Section 4.33(a), the covenants set forth in Sections 4.08 and 4.20 shall be of no further force and effect and shall be replaced with the following:

“The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, permit, suffer to exist or otherwise be or become liable with respect to, contingently or otherwise (collectively, “incur”), any Indebtedness and the Company will not permit any of its Restricted Subsidiaries to issue preferred stock; provided, however, that the Company and any Guarantor may incur Indebtedness or directly or indirectly create or incur or otherwise be or become liable with respect to any Guarantee if such Indebtedness or Guarantee would have been permitted to be incurred pursuant to any of clauses (d) through (r) of Section 4.08 (prior to giving effect to the change in covenants contemplated by this paragraph or any of the following conditions are satisfied:
