The focus of the present paper is to obtain the sharp upper bounds of a2(α) and a3(α) for functions belonging to the Bazilevic class B(α,n,γ,φ) associated with modified sigmoid function. The connection of these bounds to the celebrated Fekete-Szego functional |a3(α)- μa22(α)| follows as simple consequence.
