  Since baryon number B and lepton number L are no longer automatically
conserved once the standard model is extended to include supersymmetry, the
usually assumed conservation of R parity is an imposed condition. For a more
satisfactory realization of supersymmetry, we propose here a new model which
conserves R automatically. It is unifiable under SO(14) and has exotic fermions
at the 100 GeV scale. One important result is the enhancement of the
Higgs-boson decay rates into two gluons and into two photons by factors of 25
and 15 respectively.
