  We investigate the production of the newly found pentaquark exotic baryon
Xi_5 in the bar{K} N -> K Xi_5 and the bar{K} N -> K* Xi_5 reactions at the
tree level. We consider both positive- and negative parities of the Xi_5. The
reactions are dominated by the s- and u-channel processes, and the resulting
cross sections depend very much on the parity of Xi_5 and on the type of form
factor. We have seen that the cross sections for the positive-parity Xi_5 are
generally about a hundred times larger than those of the negative-parity one.
This large difference in the cross sections will be useful for further study of
pentaquark baryons.
