We study $\phi a_0\gamma$- and $\phi\sigma\gamma$-vertices in the framework
of the light cone QCD sum rules and we estimate the coupling constants g$_{\phi
a_0\gamma}$ and g$_{\phi\sigma\gamma}$ utilizing $\omega\phi$-mixing. We
compare our results with the previous estimations of these coupling constants
in the literature obtained from phenomenological considerations.
