A gauge theory is introduced with the gauge group SU(4){direct product}SU(2){sub {ital L}}{direct product}U(1){sub {ital y}{prime}}. In this theory the quarks transform under the fundamental four-dimensional representation of SU(4). Gauge anomaly cancellation is imposed on the known fermion generation structure (with four colors) to fix the U(1){sub {ital y}{prime}} charges. It is shown that the model requires the existence of only one extra Higgs multiplet to break the SU(4) group to SU(3){sub {ital c}} and at the same time give the exotic SU(3){sub {ital c}}-singlet quarks mass. The model has the novel feature that the unbroken electric charge generator is embedded in all three simple factor groups of the semisimple gauge group.
