Abstract
An explicit model realizing parton-hadron duality and fitting the data is suggested. Complex nonlinear Regge trajectories are important ingredients of the model. The inclusion of and N^* trajectories should account for all resonances in the direct channel. The exotic trajectory is responsible for the smooth background.
