The exclusive FCNC beauty semileptonic decay B-> \rho is studied using Wardidentities in a general vector meson dominance framework, predicting vectormeson couplings involved. The long distance contributions are discussed whichresults to obtain form factors and |V_ub|. A detailed comparison is given withother approaches.Comment: 30 pages+four postscript figures, an Appendix adde
