Abstract: We verify the validity of the low-energy theorem for emission of soft photons in the case of two particles which interact via an exchange potential. To lowest order in $K$, the photon momentum, we define the amplitude for emission from exchange currents, and show that it cancels part of the amplitude arising from internal nucleon lines. Comparison is made with the definition of exchange currents made by other authors.
