ImageJ 1.35q will have a Process>Math>Exp command. In the meantime, use
this macro code:

       for (y=0; y<getHeight; y++) {
           for (x=0; x<getWidth; x++) {
               putPixel(x, y, exp(getPixel(x, y)));
           }
           if (y%20==0)  showProgress(y, getHeight);
        }
        resetMinAndMax;
