The spontaneous breaking of (SU(3))/sup 3/ symmetry to SU(3) x SU(2) x U(1) due to nonrenormalizable interactions in the three-generation Calabi-Yau superstring model is considered. It is seen that these models lead naturally to intermediate scales M/sub I//similar to/10/sup 15/ GeV with simultaneous formation of N and ..nu../sup c/ vacuum expectation values (VEV's). The lowest-lying extrema automatically preserve matter parity and hence protect the model against too rapid proton decay. Models with matter parity also protect against electroweak Higgs VEV's from forming at M/sub I/. The intermediate mass scale produces some particles with mass O(M/sub I/). It also implies the existence of others with mass /similar to/1 TeV, which are possibly accessible to low-energy experiments.
