In this paper we have derived an exact analytical expression for exchange energy of quarks corresponding to the potential V(r,T) ~ -r^-n e^{-2 m_D(T)r} with n =1 and 2 in the limit when chemical potential m_a< 0 and m_a >> T. We have also computed numerically the same both in the non-relativistic and relativistic regions.
