The structure of the pole-cut combination in πN charge-exchange scattering for t<~0 is represented by a pair of complex poles. Excellent fits to the πN charge-exchange differential cross section, polarization, and total cross-section difference σt(π-p)-σt(π+p) are obtained for the two examples considered, Imα=gsqrt[-t] and Imα=g. The phases of the residues are allowed to vary and a zero in ImA′(-) (the "crossover" zero) is obtained.
