  A simple dynamical model for the exotic waves with $I^G(J^{PC})=1^-(1^{-+})$
in the reactions $\rho\pi\to\rho\pi$, $\rho\pi\to\eta\pi$,
$\rho\pi\to\eta'\pi$, $ \rho\pi\to(K^*\bar K+\bar K^*K)$, and in the related
ones, is constructed beyond the scope of the quark-gluon approach. The model
satisfies unitarity and analyticity and uses as a "priming" the anomalous
non-diagonal $VPPP$ interaction which couples together the four channels
$\rho\pi$, $\eta\pi$, $ \eta'\pi$, and $K^*\bar K+\bar K^*K$. The possibility
of the resonance-like behavior of the $I^G(J^{PC})=1^-(1^{-+})$ amplitudes
belonging to the $\{10\}- \{\bar{10}\}$ and $\{8\}$ representations of SU(3) as
well as their mixing is demonstrated explicitly in the 1.3--1.6 GeV mass range
which, according to the current experiments, is really rich in exotics.
