Nucleon-nucleon potential is given in coordinate space starting from the Bethe-Salpeter equation appropriate to elastic scattering at the intermediate energy region. The next order in the potential is added to construct the scattering wave for ${}^3S_1$ state. The constant terms have an effect on the spin observables particularly at the center of mass angle $\theta=90^{\circ}$
