• Discussions are given of possible solutions for the Finite Energy Sum Rules (FESR), applied to baryon-antibaryon scattering, with or without assuming resonances in exotic channels. Exotic resonances, assuming they exist, are classified, as a result of factorization, according to 36-plet, 18-plet, <18>^^--plet and nonet. It is then shown that these mesons are required to obey an equal spacing mass formula and nonet-like couplings, which are direct extensions of the ideal nonet scheme for 1^1 and 2^+ mesons. When there are no resonances in exotic channels, the idea of duality between ordinary meson resonances is not applicable to baryon-antibaryon scattering. However, by extending the concept of the duality, it is possible to find a solution of the FESR. We construct an explicit formula with such extended duality, where Regge cuts as well as Regge poles appear in the amplitude in question.
