dc.description.abstract	The cloudy bag model (CBM) is extended to incorporate chiral SU(3)XSU(3) symmetry, in order to describe 5-wave KN and KN scattering. In spite of the large mass of the kaon, the model yields reasonable results once the physical masses of the mesons are used. We use that version of the CBM in which the mesons couple to the quarks with an axial-vector coupling throughout the bag volume. This version also has a meson-quark contact interaction with the same spin-flavor structure as the exchange of the octet of vector mesons. The present model strongly supports the contention that the A*(1405) is a FYX bound state.	en
