This is an extension of the earlier work of Gardner and Moniz (Phys. Rev. C 36, 2504 (1987)) in the context of the quark-exchange model, in which effective hadron theories were constructed and their resulting physical observables were compared to the exact observables defined by the underlying quark model. The earlier U(1) study of the binding energy and form factor of a {ital q}{sup 2}{ital {bar q}} {sup 2} system is augmented, and it is extended in two different ways. First, the momentum distribution in U(1) color is now examined as well, since it is an observable which manifests behavior qualitatively distinct from that of an inert meson description; and, second, the hadronic theory construction is generalized to SU({ital N}) color.
