We present results of a search for the decays B{sup 0}{yields}l{sup +}l{sup -}{gamma} (l=e or {mu}). The search is performed using 320x10{sup 6} BB pairs collected at the {upsilon}(4S) resonance with the BABAR detector at the PEP-II B Factory at SLAC. We find no significant signal and set the following branching fraction upper limits at the 90% confidence level: B(B{sup 0}{yields}e{sup +}e{sup -}{gamma})<1.2x10{sup -7} and B(B{sup 0}{yields}{mu}{sup +}{mu}{sup -}{gamma})<1.6x10{sup -7}.
