  We predict the differential cross sections for $e^-p$ and $e^+p$ elastic
scattering in the PRad-\Rom{2} energy region. The prediction is based on form
factors obtained in our previous high-precision analysis of space- and
time-like data from dispersion theory and different sets of two-photon exchange
corrections. We investigate the sensitivity of the cross sections to two-photon
exchange effects and find that the differences between model calculations and
phenomenological extractions of the two-photon corrections can not be resolved
if the uncertainty in the form factors is taken into account.
