  Contributions from the reaction e+e- --> pi+pi- e+e- to the pion form factor
measurement via radiative return method are discussed basing on the results of
a Monte Carlo generator (EKHARA). The generator contains contributions from the
initial and final state emission of a e+e- pair from e+e- --> pi+pi- production
diagrams and the pi+pi- pair production from space-like and time-like Bhabha
diagrams. A detailed study is performed for the Phi- factory energy. Tests of
the generation procedure are also presented.
