Coherent $\eta $-meson photoproduction from nuclei is considered within an extended analogue of the $\Delta $-hole model taking into account the configuration mixing of baryon-hole excitations of different sorts. Calculated integrated and differential cross sections for reactions $^{12}C(\gamma ,\eta )^{12}C_{g.s.}$ and $^{16}O(\gamma ,\eta )^{16}O_{g.s.}$ demonstrate an important role of the exchange interaction between intermediate $D_{13}(1520)$-hole and $S_{11}(1535)$-hole excitations.
