On the Increase Closing Date, each Lender shall, to the extent necessary, make a payment to Agent in an amount sufficient, upon the application of such payments by all Lenders to the reduction of outstanding Loans held by Lenders, to cause the principal amount of Loans outstanding made by each Lender to be in the amount of its pro rata share (after giving effect to the increase in the Commitments in accordance with this paragraph 2.12) of all outstanding Loans. Borrower hereby irrevocably authorizes each Lender to fund to Agent the payment required to be made pursuant to the immediately preceding sentence for application to the reduction of the outstanding Loans held by the other Lenders. If, as a result of the repayment of Loans provided for in this paragraph 2.12, any payment of LIBOR Based Loans occurs on a day which is not the last day of the applicable Interest Period, Borrower will pay to Agent for the benefit of any Lender holding a LIBOR Based Loan any Lender’s Consequential Loss incurred by such Lender resulting therefrom in accordance with paragraph 3.1.4 to the extent a LIBOR Based Loan is paid on other than the last day of an Interest Period as a result thereof.
