  In this paper, which is the second part in a series of two, we construct tree
level baryon exchange and resonance amplitudes for $\pi N$ / $MB$-scattering in
the framework of the Kadyshevsky formalism. We use this formalism to formally
implement absolute pair suppression, where we make use of the method of
Takahashi and Umezawa. The resulting amplitudes are Lorentz invariant and
causal. We continue studying the frame dependence of the Kadyshevsky integral
equation using the method of Gross and Jackiw. The invariant amplitudes,
including those for meson exchange, are linked to the phase-shifts using the
partial wave basis.
