The electrical conductivity of a two-dimensional disordered system has been calculated taking into consideration an exponential density of states. The effect of backscattering has been calculated. For an exponential density of states the diffusion pole has been removed. In the Ω→0 limit we showed that there exists a critical concentration that corresponds to the transition point from the metallic to the insulating phase.
