We study some of the consequences of the SU(6){sub {ital L}}{direct_product}U(1){sub {ital Y}} model of unification of electroweak interactions and families with a horizontal gauge group SU(2){sub {ital H}}, paying special attention to processes with flavor-changing neutral currents. We compute at the tree level the decays {ital K}{sup +}{r_arrow}{pi}{sup +}{mu}{sup +}{ital e}{sup {minus}}, {ital K}{sub {ital L}}{sup 0}{r_arrow}{mu}{sup +}{ital e}{sup {minus}}, and {mu}{sup {minus}}{r_arrow}{ital e}{sup {minus}}{bar {nu}}{sub {ital e}}{nu}{sub {mu}} from which we obtain lower bounds for the mass of the horizontal gauge boson associated with FCNC`s. Finally we obtain limits on the mixing between ordinary and exotic charged leptons.
