IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be duly executed by their duly authorized officers, all as of the day and year first above written.

The foregoing pricing grid is based upon the Borrower’s Senior Debt (“Index Debt”) ratings as determined from time to time by S&P and Moody’s. For purposes of the foregoing, (i) if both S&P and Moody’s shall not have in effect a rating for the Index Debt (other than by reason of the circumstances referred to in the last sentence of this paragraph), then such rating agencies shall be deemed to have established a rating in Level 6, (ii) in the event either S&P or Moody’s shall not have in effect a rating for the Index Debt (other than by reason of the circumstances referred to in the last sentence of this paragraph), then the foregoing pricing grid will be based upon the Borrower’s Index Debt ratings as determined solely with respect to the other rating agency, (iii) in the event that the Borrower’s Index Debt ratings from S&P and Moody’s fall in different levels, then the Applicable Margin and Commitment Fee in the above pricing grid will be that applicable to the higher rating, unless one of the two ratings is two or more levels lower than the other, in which case the Applicable Margin and Commitment Fee in the above pricing grid will be that applicable to the rating one level lower than the higher rating, and (iv) if the ratings established or deemed to have been established by S&P and Moody’s for the Index Debt shall be changed (other than as a result of a change in the rating system of S&P or Moody’s), such change shall be effective as of the date on which it is first announced by the applicable rating agency. Each change in the Applicable Margin and Commitment Fee shall apply during the period commencing on the effective date of such change and ending on the date immediately preceding the effective date of the next such change. If the rating system of S&P or Moody’s shall change, or if either such rating agency shall cease to be in the business of rating corporate debt obligations, the Borrower and the Lenders shall negotiate in good faith to amend this definition to reflect such changed rating system or the unavailability of ratings from such rating agency and, pending the effectiveness of any such amendment, the Applicable Margin and Commitment Fee shall be determined by reference to the rating most recently in effect prior to such change or cessation.
