  We discuss the non-factorizable terms in color suppressed (Class II) decays.
Our emphasis is on the non-perturbative soft gluon exchange mechanism, which
has been previously found to be responsible for the rule of discarding $
1/N_{c} $ in the Class I decays. The non-factorizable contribution to the
decays $ \bar{B}^{0} \rightarrow D^{0} \pi^{0} $ at the tree level is estimated
within the light cone QCD sum rule method which combines the technique of the
QCD sum rules with the description of the pion in terms of the set of wave
functions of increasing twist. We find that the same soft gluon exchange
mechanism tends to cancel the $ 1/N_{c} $ term in the factorized amplitude.
