  We consider a Galilean N=2 supersymmetric theory in 2+1 dimensions with
F-term couplings, obtained by null reduction of a relativistic Wess-Zumino
model. We compute quantum corrections and we check that, as for the
relativistic parent theory, the F-term does not receive quantum corrections.
Even more, we find evidence that the causal structure of the non-relativistic
dynamics together with particle number conservation constrain the theory to be
one-loop exact.
