Next, we apply the model to calculate non-exotic and exotic mass spectra. We concentrate on large $N_{c}$ counting both for mass splittings and decay widths. It is shown that pure large $N_{c}$ arguments do not explain the small width of exotic pentaquark states.Presented at the Cracow Epiphany Conference on Hadron Spectroscopy, Cracow, Poland, January 6-8, 2005High Energy Physics - Phenomenologytext
