With the first data sample collected by the CLEO-c detector at the {psi}(3770) resonance we have studied four exclusive semileptonic decays of the D{sup 0} meson. Our results include the first observation and absolute branching fraction measurement for D{sup 0}{yields}{rho}{sup -}e{sup +}{nu}{sub e} and improved measurements of the absolute branching fractions for D{sup 0} decays to K{sup -}e{sup +}{nu}{sub e}, {pi}{sup -}e{sup +}{nu}{sub e}, and K*{sup -}e{sup +}{nu}{sub e}.
