Superstring models are considered where there is E{sub 6} flux breaking to (SU(3)){sup 3} at compactification and dynamical breaking of (SU(3)){sup 3} to SU(3){sub {ital C}}{times}SU(2){sub {ital L}}{times}U(1){sub {ital Y}} at an intermediate scale {ital M}{sub {ital I}}. If the intermediate scale breaking preserves matter parity (to stabilize the proton) and is triggered by supersymmetry breaking, then it is shown that there will always be at least two, and often four, new light SU(3){sub {ital C}}{times}SU(2){times}U(1) neutral chiral multiplets (in addition to the usual standard-model states). The interactions of these new particles with the standard-model particles are deduced and are expected to produce {mu}{r arrow}{ital e}{gamma} decay and, in some cases, neutrino masses and oscillations in a range that may be accessible to experiment.
