  We use the new symmetries in the heavy quark limit to calculate the exclusive
B-decays $B \rightarrow K^i \psi $ where $K^i$ are higher resonances of
K-meson. We then estimate the long distance contributions to $B \rightarrow K^i
\gamma $ decays via $\psi - \gamma$ conversion. The results point to around $30
\%$ uncertainty in the top quark mass determined by measurements of rare
B-decays $B \rightarrow K^i \gamma$.
