  Given presently known empirical information about the exotic Theta+ baryon,
we analyze possible properties of its SU(3)F partners, paying special attention
to the nonstrange member of the antidecuplet N*. The modified PWA analysis
presents two candidate masses, 1680 MeV and 1730 MeV. In both cases the N*
should be highly inelastic. The theoretical analysis, based on the soliton
picture and assumption of Gamma(Theta+) < 5 MeV, shows that most probably
Gamma(N*) < 30 MeV. Similar analysis for Xi3/2 predicts its width to be not
more than about 10 MeV. Our results suggest several directions for experimental
studies that may clarify properties of the antidecuplet baryons, and structure
of their mixing with other baryons.
