Abstract	We present recent results on study of exclusive processes of $e^+e^-$ annihilation into hadrons with the SND detector. Data were collected at the VEPP-2000 $e^+e^-$ collider in the center-of-mass energy range from 0.3 to 2 GeV. In particular, we have measured the cross sections for $e^+e^- \to \pi^+ \pi^-$ and $nn^-$ studied the radiative decay of excited light vector mesons to $\eta \pi^0 \gamma$, and performed a search for the rare processes of $e^+e^-$ annihilation into $C-$even resonances $\eta$ and $f_1$(1285).
