In this paper we study the possibilities of the production and decay of one of these exotic quarks at CERN LEPII-LHC collider. For typical vector bilepton, exotic quark masses and mixing angles we obtained between 20 and 750 events per year. Angular distributions are also presented.5 pages, RevTex 3.1, 9 eps figures, to appear in Phys. Rev. DHigh Energy Physics - Phenomenologytext
