Recent interest in horizontal symmetry model building has been driven mainly by the large top mass and hence strong hierarchy in quark masses, and the possibility of appropriately constrained soft squark mass matrices, in place of an assumed universality condition, for satisfying the relevant flavor changing neutral current constraints. Here we present the first successful supersymmetric SU(5) model that has such a feature. The horizontal symmetry is a gauged {sub {ital H}} {improper_subset}{sub {ital H}}. All nonrenormalizable terms compatible with the symmetry are allowed in the mass matrix constructions. Charged lepton masses can also be accommodated. {copyright} {ital 1996 The American Physical Society.}
