N2 - A prediction for the contributions of chiral loops and the L$\sigma$M model to the radiative $\phi\to\pi^0\eta\gamma$ decay mode is presented. The L$\sigma$M is used as an appropriate framework for describing the pole effects of the $a_0(980)$ scalar resonance. As a result, a better agreement with present available data is achieved for the higher part of the $\pi^0\eta$ invariant mass spectrum. For the branching ratio, a value of $B(\phi\to\pi^0\eta\gamma)=(0.75$--$0.95)\times 10^{-4}$ is found.
