We study soft supersymmetry breaking parameters in a supersymmetric unified model which potentially solves the doublet-triplet splitting problem. In the model the doublet-triplet splitting is solved by the discrete symmetry which is allowed to be introduced due to the direct product structure of the gauge group. The messenger fields for the gauge mediated supersymmetry breaking are naturally embedded in the model. The discrete symmetry required by the doublet-triplet splitting makes the gaugino masses nonuniversal and also induces a different mass spectrum for the scalar masses from the ordinary minimal gauge mediation model. Independent physical CP phases can remain in the gaugino sector even after the R transformation.
