The general purpose detector CMD-2 at the VEPP-2M electron-positron collider at Novosibirsk has collected about 11 pb{sup {minus}1} of integrated luminosity in the center-of-mass energy range from 0.36 up to 1.38 GeV. Data in the {rho}-meson energy range from 0.61 to 0.96 GeV have been analysed and preliminary results on the e{sup +}e{sup {minus}}{r_arrow}{pi}{sup +}{pi}{sup {minus}} cross-section in this energy range are presented. {copyright} {ital 1998 American Institute of Physics.}
