The authors derive the Bethe-Salpeter equation for bound states of a four-body system. They treat only two-body interaction kernels in the ladder approximation. The equations should be applicable for the description of exotic meson states (q qq-barq-bar states) and the ''poly-positronium'' states discussed in connection with the interpretation of the narrow coincidence peaks in the spectra of electrons and positrons observed in heavy ion collisions.
