  We consider Floer homology associated to a pair of closed Lagrangian
submanifolds that satisfy a monotonicty assumption. If the Lagrangians
intersect cleanly we decribe two spectral sequences which help to compute their
Floer homology. The spectral sequences are constructed using a Morse-Bott
version of Floer homology. We give a full treatment of the theory including
orientations.
