Applicable Rate

Any increase or decrease in the Applicable Rate resulting from a change in the Consolidated Leverage Ratio shall become effective as of the first Business Day immediately following the date a Compliance Certificate is delivered pursuant to Section 6.01(c); provided, however, that if a Compliance Certificate is not delivered when due in accordance with such Section, then, upon the request of the Required Lenders, Pricing Level 5 shall apply as of the first Business Day after the date on which such Compliance Certificate was required to have been delivered and shall remain in effect until the date on which such Compliance Certificate is delivered.

The Applicable Rates set forth below based upon the Borrower’s Credit Ratings, and any change in the Credit Ratings which would cause it to move to a different Level shall be effective as of the first day of the first calendar month immediately following receipt by the Administrative Agent of written notice delivered by the Borrower in accordance with Section 6.02(e) that the Borrower’s Credit Ratings have been received or changed; provided, however, if the Borrower has not delivered the notice required by such Section but the Administrative Agent becomes aware that the Borrower’s Credit Ratings have changed, then the Administrative Agent may, in its sole discretion, adjust the Level effective as of the first day of the first calendar month following the date the Administrative Agent becomes aware that the Borrower’s Credit Ratings have changed. During any period that the Borrower has received two Credit Ratings that are not equivalent, the Applicable Rate shall be determined based on the Level corresponding to the higher of such two Credit Ratings, unless the split is more than one Level, in which case the Level shall be one Level higher than that corresponding to the lowest Credit Rating.

Notwithstanding anything to the contrary contained in this definition, the determination of the Applicable Rate for any period shall be subject to the provisions of Section 2.11(b).
