By supplementing the standard SU(5) Lagrangian with nonrenormalizable (dimension five) terms which are needed in any case to obtain acceptable masses for the first two fermion generations, the proton decay predictions can be neatly reconciled with the ongoing experiments. We present a class of such models in which the dominant decay mode of the proton is ..mu../sup +/K/sup 0/. A triplet of colored Higgs bosons of mass approx.10/sup 12/ GeV, required for successfully implementing the inflationary scenario, mediate this and other decays.
