We examine a superpotential for an SO(10) GUT and show that if the parameters of the superpotential are in a certain region, the SO(10) GUT has an intermediate symmetry SU(2){sub {ital L}}{circle_times}SU(2){sub {ital R}}{circle_times}SU(3){sub {ital C}}{circle_times}U(1){sub {ital B}{minus}{ital L}} which breaks down to the group of the standard model at an intermediate scale 10{sup 10}{endash}10{sup 12} GeV. In the model, by the breakdown of the symmetry, right-handed neutrinos acquire a mass of the intermediate scale through a renormalizable Yukawa coupling. {copyright} {ital 1996 The American Physical Society.}
