Using the freedom in SO(10) GUT's one can generalize the existing modelswithout changing the mass spectrum of fermions to obtain a significantsuppression of proton decay resulting from the baryon number violatingoperators of dimension 5. In some limiting cases, their contributions can bemade negligible compared to the dimension 6 operators resulting from the heavygauge bosons exchange.Comment: 19 pages, 3 Postscript figures, 2 mpost figures, rearranged plots, corrected typo
