Using 226 million BBbar events recorded on the
Y(4S) resonance with the BABAR detector at the SLAC e+e-
storage rings PEPII,
we reconstruct B- --> D*0 e- nubar decays using the decay chain
D*0 --> D0 pi0 and D0 --> K- pi+.
From the dependence of their differential rate on w, 
the product of the four-velocities of B- and D*0,
and using the description of the
form factor F(w) by Caprini et al.,
we obtain the preliminary results 
rho^2_{A_1}             = 1.15  +- 0.06 +- 0.08, 
F(1)|Vcb|               =(36.3  +- 0.6  +- 1.4) 10^-3, and 
BF(B- --> D*0 e- nubar) = (5.71 +- 0.08 +- 0.41)%. 
The first errors are statistical and the second ones are systematic.
