  The event structure associated with the production of massive photon pairs is
studied to ${\cal O}(\alpha^2/alpha_s)$. The cross sections for two photon and
two photon plus one jet events are given. The Dalitz plot structure of events
with two photons and a jet is also presented. These distributions will provide
checks on our understanding of the production mechanisms for massive photon
pairs, a signal thought to be important for searches for the Higgs boson in the
intermediate mass region.
