Based on a data sample of 60 pb-1 collected at the psi(3770) resonance with the CLEO-c detector at CESR, we present improved measurements of absolute branching fractions for exclusive D0 semileptonic decays into K- e+ nu, pi- e+ nu and K*- e+ nu; and the first observation and absolute branching fraction measurement of D0 to rho- e+ nu.
