  The cross sections for electron induced two-nucleon knockout reactions are
evaluated for the example of the $^{16}$O(e,e$'$pn)$^{14}$N reaction leading to
discrete states in the residual nucleus $^{14}$N. These calculations account
for the effects of nucleon-nucleon correlations and include the contributions
of two-body meson exchange currents as the pion seagull, pion in flight and the
isobar current contribution. The effects of short-range as well as tensor
correlations are calculated within the framework of the coupled cluster method
employing the Argonne V14 potential as a model for a realistic nucleon-nucleon
interaction. The relative importance of correlation effects as compared to the
contribution of the meson exchange currents depends on the final state of the
residual nucleus. The cross section leading to specific states, like e.g. the
ground state of $^{14}$N, is rather sensitive to the details of the correlated
wave function.
