Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, prepay and reborrow amounts under the subfacility for Swingline Loans provided for in this Section 2.08, provided that, for the avoidance of doubt, in no event may the Borrower continue or convert a Swingline Loan.

Each such notice shall be irrevocable and shall specify the requested date (which shall be a Business Day) and amount of the requested Swingline Loan. The Administrative Agent will promptly advise the applicable Swingline Lender of (i) the current aggregate Revolving Credit Exposures and (ii) the undrawn portion of the Commitments available to make Swingline Loans. To the extent that the applicable Swingline Lender receives the information referred to in the immediately preceding sentence no later than 4:00 p.m., New York City time, then the applicable Swingline Lender shall make such Swingline Loan available to the Borrower by means of a credit to the general deposit account of the Borrower by 5:00 p.m., New York City time, on the requested date of such Swingline Loan. Each Swingline Borrowing shall be in an amount that is an integral multiple of $250,000 and not less than $1,000,000.
