If such leverage ratio is greater than or equal to 3.0 to 1.0 as of the end of the most recently ended four fiscal quarter period the applicable margins for interest rates applicable to amounts outstanding under the Credit Agreement will be a range of 150 to 250 basis points above the applicable reference rate for Eurodollar loans and 50 to 150 basis points above the applicable reference rate for alternate base rate loans. The Credit Agreement Amendment also maintained the borrowing base under the Credit Agreement at $1,500,000,000.
