The e(+)e(-)->omega, rho ->pi(0)e(+)e(-) processes have been investigated in the experiments with Spherical Neutral Detector at the VEPP-2M e(+)e(-) collider. The measurements provide the probability B(omega ->pi(0)e(+)e(-)) = ( 0.761 +/- 0.053 +/- 0.064) x 10(-3) of the omega ->pi(0)e(+)e(-) conversion decay and the upper limit B(omega ->pi(0)e(+)e(-)) < 1.2 x 10(-5) (at 90% CL) for the rho ->pi(0)e(+)e(-) decay. The transition form factor was measured at three values of the 4-momentum transfer squared.
