  Exclusive nonleptonic bottom meson decays are studied in the covariant
osillator quark model using the factorization assumption. The main feature of
this model is that it can simultaniously be applied to both heavy to heavy and
heavy to light transitions, satisfying the constraints of the heavy quark
effective theory (HQET) in the appropriate limit. The results obtained are in
overall agreement with the present experimental data for various B decays.
