  In this paper we model the emission from a relativistically expanding
electron-positron pair plasma fireball originating near the surface of a heated
neutron star. This pair fireball is deposited via the annihilation of neutrino
pairs emanating from the surface of the hot neutron star. The heating of
neutron stars may occur in close neutron star binary systems near their last
stable orbit. We model the relativistic expansion and subsequent emission of
the plasma and find 10^51 to 10^52 ergs in gamma-rays are produced with
spectral and temporal properties consistent with observed gamma-ray bursts.
