The fermion mass and mixing angle predictions of a recently proposed framework are investigated for large [ital b] and [tau] Yukawa couplings. A new allowed region of parameters is found for this large tan[beta] case. The two predictions that are substantially altered, [ital m][sub [ital t]] and tan[beta], are displayed, including the dependence on the input [vert bar][ital V][sub [ital c][ital b]][vert bar], [ital m][sub [ital c]], [ital m][sub [ital b]], and [alpha][sub [ital s]]. A simple restriction on this framework yields an additional prediction for [vert bar][ital V][sub [ital c][ital b]][vert bar]. If the [ital b], [ital t], and [tau] Yukawa couplings are equal at the GUT scale then [vert bar][ital V][sub [ital c][ital b]][vert bar] is predicted and the top quark mass is constrained to lie in the range [ital m][sub [ital t]]=179[plus minus]4 GeV.
