  We propose that a gamma-ray burst in one member of a binary may induce a
supernova-like explosion of a close, white-dwarf companion. Such an explosion
might be brought about in rather light companions, which cannot undergo the
standard accretion-induced explosion. This would give some GRB-associated
supernova an appearance rather unlike that of the typical Type I. GRB 980425,
if indeed associated with SN 1998bw, is too weak to have produced it through
our proposed mechanism.
