*Finite-t Corrections to Hard Off-Forward Reactions *

We develop a general approach to the calculation of kinematic corrections ? t/Q2, m2/Q2 
in hard processes which involve momentum transfer from the initial to the final hadron state. 
As the principal result, the complete expression is derived for the time-ordered product of 
two electromagnetic currents that includes all kinematic corrections to twist-four accuracy. 
The results are immediately applicable, e.g. to the studies of deeply-virtual Compton scattering.
