  A model for deeply virtual Compton scattering, based on analytical light-cone
hadron wave functions is presented and studied at energies currently accessible
at Jefferson Laboratory, DESY, and beyond. It is shown that perpendicular
vector components play an important role at Q^2 < 10 GeV^2 and that the
meson-exchange diagrams are important at all energies. This could significantly
impact the physical interpretation of the underlying hadron amplitudes.
