We report on our study of the meson correlators calculated with two flavors of dynamical overlap quarks in the epsilon-regime at a fixed topology Q=0. With small quark masses, statistical signal of the scalar and pseudo-scalar correlators is substantially improved by the low-mode averaging technique. We compare the lattice results with the theoretical predictions of chiral perturbation theory to extract the chiral condensate and the pion decay constant.
