  Predictions for the low-lying excitation spectrum of positive parity
pentaquark systems containing one c or b antiquark and four light u,d quarks
are obtained in the quark model picture for models with spin-dependent
interactions given either by effective color magnetic (CM) exchange or
effective Goldstone boson (GB) exchange. For the GB model, 4 excited states are
predicted to lie within roughly the N-Delta splitting of the J=1/2 positive
parity ground state while, for the CM model, 10 states are expected in the same
range. Both the lowest excitation energy and the relative splittings are much
smaller in the CM case. These predictions are on the same footing as those for
the analogous splittings in the non-exotic baryon sector and, as such, provide
a means of not only testing the models, but potentially ruling out either one,
or both.
