We consider the contributions of the exotic quarks and gauge bosons to themass difference between the short- and the long-lived neutral kaon states in$SU(3)_C \times SU(3)_L \times U(1)_N$ model. The lower bound $M_{Z'} \sim$ 14TeV is obtained for the extra neutral gauge boson ${Z'}^0$. Ranges for valuesof one of the exotic quark masses and quark mixing parameters are alsopresented.Comment: 4 pages, Revtex 3.0, two eps figures. (To appear in Phys. Rev. D.
