  A new Monte Carlo event generator for wide angle Bhabha scattering and muon
pair production in $e^+e^-$ collisions is described. The program includes
complete one-loop electroweak corrections, and QED radiative corrections. The
O($\alpha$) QED correction uses the exact matrix element. Higher order QED
corrections are included in an improved soft photon approximation with
exponentiation of initial state radiation. Events are generated in the full
phase space of the final state including explicit mass effects in the region of
collinear mass singularities. The program is intended for centre of mass
energies around and above the Z peak and for Bhabha scattering at angles
greater than $10^{\circ}$ .
