  In this talk I report on a thorough comparison between the bound state and
rigid rotator approaches to generate baryon states with non--zero strangeness
in chiral soliton models. This comparison shows that the scattering amplitude
in the bound state approach contains contributions generated by the exchange of
the rigid pentaquark excitation, and that the two approaches are consistent
with each other in the large $N_C$ limit. The comparison paves the way to
unambiguously compute the width of the $\Theta^+$ pentaquark in chiral soliton
models.
