Data collected with the BABAR detector at the PEP-II asymmetric B Factory at SLAC are used to measure the lifetimes of the B0 and B+ mesons. The data sample consists of 8.3 fb-1 collected near the ϒ(4S) resonance. B0 and B+ mesons are fully reconstructed in several exclusive hadronic decay modes to charm and charmonium final states. The B lifetimes are determined from the flight length difference between the two B mesons. The preliminary measurements of the lifetimes are and their ratio is
