Electroproduction of neutral pions in exclusive reaction $p(e,e'\pi^0)p$ isstudied above the resonance region, $\sqrt{s}>2$ GeV. The reaction amplitude isdescribed by exchanges of vector $\omega(782)$, $\rho(770)$ and axial-vector$h_1(1170)$ and $b_1(1235)$ Regge trajectories. The residual effect of $s$- and$u$-channel nucleon resonances is taken into account using a dual connectionbetween the exclusive form factors and inclusive deep inelastic structurefunctions. In photoproduction at forward angles the exchange of Reggetrajectories dominates and the dip region is filled by the resonances. Inelectroproduction the excitation of nucleon resonances explains the high $Q^2$data from JLAB. The results for the beam spin azimuthal asymmetry measured atCLAS/JLAB are presented. Model calculations in the deep inelastic region atHERMES/DESY are given.
