The model retains the significant Minimal Supersymmetric Standard Model predictions for $sin^2 θ_w$ and $α_s$ and contains an automatic $Z_2$ matter parity. Proton decay through $d=5$ operators is sufficiently suppressed. It is remarkable that no global symmetries need to be imposed on the model.11 pages, LaTeX, UT-STPD-2-94High Energy Physics - Phenomenologytext
