  By introducing electromagnetic formfactors in the spacelike region we extend
an effective, gauge invariant Lagrangian model considering Born terms, baryon
resonances up to 1.7 GeV and vector meson contributions (Rho, Omega) to
calculate electroproduction of Pi-mesons. This model forms the basis for
predictions of pion induced dilepton production on the nucleon. Therefore, the
implemented formfactors are constructed in such a way that their analytic
continuation into the timelike region is possible. It is shown that the seagull
term and the N*(1520) resonance play a dominant role in the dilepton
production.
