The hard exclusive electroproduction processes provide new information about
hadronic structure accumulated in nonforward parton distributions. The NFPD's
are universal hybrid functions having the properties of parton densities,
hadronic form factors and distribution amplitudes. They give a unified
description of various hard exclusive and inclusive reactions. The basic
supplier of information about nonforward parton distributions is deeply virtual
Compton scattering which offers a remarkable example of Bjorken scaling
phenomena in exclusive processes. Wide-angle real Compton scattering is an
ideal tool to test angle-dependent scaling laws characteristic for soft overlap
mechanism. Hard meson electroproduction is the best candidate to see pQCD hard
gluon exchange in exclusive reactions.Comment: 11 pages, Latex, 6 figures; Contribution to proceedings of the
