If any Lender incurs any cost or expense that this Agreement entitles it to collect from the Borrower, such cost or expense shall be payable together with interest thereon at a rate per annum equal to the rate applicable to Base Rate Loans as then in effect, from the date such cost or expense is incurred until such payment date. Such Lender shall notify the Borrower, through the Administrative Agent, of the cost or expense to be paid plus the amount of interest thereon. This provision shall not apply to payments or prepayments of principal or to amounts to be applied against principal, interest or any cost or expense to be collected pursuant to Section 2.6C .
