payable with respect to "LIBOR Rate Loans" (as defined in the Credit
Agreement), and to clarify that the limitation on the amount that may be

condition of the Credit Agreement or any of the documents referred to therein,
or (b) prejudice any right or rights which the Agent or any Bank may now have
or may have in the future under or in connection with the Credit Agreement or
