The decay width, forward-backward asymmetry and tau lepton longitudinal and transversal polarization for the exclusive B --> K tau(+)tau(-) decay in a two Higgs doubler model are computed. It is shown that the forward-backward asymmetry and longitudinal polarization of the tau lepton are very effective tools for establishing near physics.
