  If gamma ray bursts produce a total energy of 10^54 ergs and this energy is
concentrated on the high energy tail of the spectrum E> 1 TeV, then they may
account for the observed diffuse extragalactic gamma ray emission for energies
> 100 MeV. Such an energy could be released if the GRB's are produced by the
burning of the total mass of a neutron star in a phase transition which
violates baryon number.
