Abstract: The factorized amplitude for pion formfactor at high Q 2 was the first case of QCD application for hard exclusive processes. It may be naturally extended to describe the exclusive Drell-Yan process by substituting of one or two pion Distribution Amplitudes by Generalized Parton Distributions. Two respective mechanisms for the lepton pair production in exclusive proton-meson collisions are considered and compared. Amplitudes and differential cross sections are calculated
