We study the lepton sector in the model based on the local gauge group SU(3){sub c}xSU(3){sub L}xU(1){sub X}, which does not contain particles with exotic electric charges. The seesaw mechanism and discrete A{sub 4} symmetry are introduced into the model to help us understand why neutrinos are especially light and have the observed pattern of neutrino mixing. The model provides a method for obtaining the tribimaximal mixing matrix in the leading order. A nonzero mixing angle V{sub e3} is presented in the modified mixing matrix.
