Exhibit A

The Facility Fee and the Applicable Margin for Eurodollar Loans shall be, at any time, the rate per annum set forth in the Pricing Grid opposite the Index Debt Rating of the Borrower by S&P, Moody’s and Fitch; provided, however that prior to the date that initial Index Debt Ratings are available from each of S&P, Moody’s and Fitch with respect to the Borrower, the rating of the senior, unsecured long-term indebtedness for borrowed money of the Guarantor (“Guarantor Debt”) issued by S&P, Moody’s and Fitch (which may be called the “corporate credit rating”, “issuer rating”, “issuer default rating”, or some similar term) and not the Index Debt Rating shall be used to determine the Facility Fee and Applicable Margin for Eurodollar Loans (and for such period all references in the body of this Agreement to an Index Debt Rating or a rating of Index Debt shall be deemed to be references instead to such ratings of the Guarantor Debt as applicable); provided, however, that if the S&P Rating, the Moody’s Rating and the Fitch Rating fall within different levels, then (i) if two of the ratings are at the same level and the other rating is one level higher or one level lower than the two same ratings, then the Facility Fee and the Applicable Margin will be based on the two ratings at the same level, (ii) if two of the ratings are at the same level and the other rating is two or more levels above the two same ratings, then the Facility Fee and the Applicable Margin will be based on the rating that is one level above the two same ratings, (iii) if two of the ratings are at the same level and the other rating is two or more levels below the two same ratings, then the Facility Fee and the Applicable Margin will be based on the rating that is one level below the two same ratings, and (iv) if each of the three ratings fall within different levels, then the Facility Fee and the Applicable Margin will be determined based on the rating level that is in between the highest and the lowest ratings. If, at any time, a rating of the Borrower’s Index Debt (or Guarantor Debt, if applicable) is available from only two of S&P, Moody’s and Fitch, then the Facility Fee and the Applicable Margin shall be based on the Index Debt Rating available from such two rating agencies. If the immediately preceding sentence is applicable and the two available ratings referred to in such preceding sentence fall within different levels, the Facility Fee and the Applicable Margin shall be determined based on the higher rating and if the ratings differ by more than one level, the Facility Fee and the Applicable Margin shall be determined based on the rating one level lower than the higher rating. If, at any time, a rating of the Borrower’s Index Debt (or the Guarantor Debt, if applicable as provided above) is available from only one of or none of S&P, Moody’s, Fitch or any other nationally recognized statistical rating organization designated by the Borrower and approved in writing by the Required Lenders (an “Approved Agency”), then the Facility Fee and the Applicable Margin for each period commencing during the 30 days following the time there ceased to be at least two such ratings available shall be the Facility Fee and the Applicable Margin in effect immediately prior to such cessation. Thereafter, the rating to be used until ratings from at least two of S&P, Moody’s, Fitch or such other Approved Agency become available shall be as agreed between the Borrower and the Required Lenders, and the Borrower and the Required Lenders shall use good faith efforts to reach such agreement within such 30-day period; provided, however, that if no such agreement is reached within such 30-day period, then the Facility Fee and the Applicable Margin

thereafter, until such agreement is reached, shall be (a) if any such rating has become unavailable as a result of S&P, Moody’s, Fitch or any other Approved Agency ceasing its business as a rating agency, the Facility Fee and the Applicable Margin in effect immediately prior to such cessation or (b) otherwise, the Facility Fee and the Applicable Margin as set forth opposite the Index Debt Rating “(BBB-/Baa3/BBB- or lower)” on the Pricing Grid. If the rating of the Guarantor Debt is used to determine the Applicable Margin and the Facility Fee, the provisions set forth in the second proviso hereof through the end of this paragraph shall apply with respect to any split rating or lack of any rating of the Guarantor Debt to the same effect as such provisions apply to the Borrower’s Index Debt.
