A simple s-channel resonance model based on a new scheme of duality is proposed and is shown to explain successfully (i) the appearance of distinct exotic peaks with slopes and relative heights similar to those of the ordinary Regge exchanges, and (ii) the rapid falloff of exotic cross sections vs energy, which have been recently observed in K-p and pp backward scattering. We also discuss the predictions of the model for the spherical-harmonic moments and the dip systematics of two-body hadronic amplitudes. In particular, the model predicts thc persistcnce of the Odorico dips as well as the usual wrong-signature- nonsense-zero dips up to high energies if the increase of Im alpha /sub s/ is not faster than linear in s. Experimental data now available support our approach. (auth)
