Abstract
Meson exchange diagrams following from a lagrangian with off-shell meson-nucleon couplings are compared with those generated from conventional dynamics. The off-shell interactions can be transformed away with the help of a nucleon field redefinition. Contributions to to the - and -potentials and nonminimal contact e.m. meson-exchange currents are discussed, mostly for an important case of scalar meson exchange.
