With the first data sample collected by the CLEO-c detector at the ψ(3770) resonance we have studied four exclusive semileptonic decays of the D0 meson. Our results include the first observation and absolute branching fraction measurement for D0→ρ-e+νe and improved measurements of the absolute branching fractions for D0 decays to K-e+νe, π-e+νe, and K*-e+νe.
