  Short and long distance contributions to the exclusive B-decays into various
K-resonances and dileptons, i.e. B --> Ki l l ( l = e, mu , nu ), are examined.
The heavy quark effective theory has been used to calculate the hadronic matrix
elements. Substantial branching fractions are obtained for the dileptonic
B-decays into some higher excited states of K-mesons. The long distance
(resonance) contributions to these exclusive rare B-decay modes dominate the
short distance contributions mostly by two orders of magnitude. It is pointed
out that, excluding the resonance contributions, the P-wave channels are
dominant, accounting for about 50% of the inclusive B --> X_s l l branching
fraction.
