Abstract
We discuss the possibility of measuring Vub via nonleptonic decays of B mesons to exclusive two-meson final states by choosing modes that are theoretically "clean." These clean final states are chosen by requiring that no qq̅ of the same flavor should occur in them. The above requirement automatically leads to decays that proceed only via the spectator graphs in the decays of b, c, and s flavored mesons. These modes may offer a good handle on Vub, at a level comparable to that given by the exclusive semileptonic modes.
