Copyright @ 2002 APS The branching fractions of the exclusive decays B0→K*0γ and B+→K*+γ are measured from a sample of (22.74±0.36)×106 BB̅ decays collected with the BABAR detector at the PEP-II asymmetric e+e- collider. We find B(B0→K*0γ) = [4.23±0.40(stat)±0.22(syst)]×10-5, B(B+→K*+γ) = [3.83±0.62(stat)±0.22(syst)]×10-5 and constrain the CP-violating charge asymmetry to be -0.170
