  In the usual derivation of Einstein's equation from action, the surface terms
are neglected. Hawking \cite{hw} gave a derivation of the gravitational
Hamiltonian keeping all surface terms. Using such surface terms Easson
et.al.\cite{ea} showed that Friedmann equation could get modified and using the
modified Friedmann equation they could explain the cosmic acceleration. We
study the effect of surface terms on a galactic scale and find that the
classical limit of the modified Friedmann equation will lead to a MOND like
acceleration term.
