       extent the proceeds thereof are used to reduce the Total Commitment in
       accordance with Section 2.11(f), (y) no consent of any Lender or the
       Agent shall be required for the release of any Collateral associated with
       the sale or other disposition of the assets described on Schedule II to
       Amendment No. 1 if the sum of the Total Commitment plus the "Total
       Commitment" (as defined in the Five Year Credit Agreement) has been, or
       is contemporaneously with such asset disposition,

                                       16
