A partial-wave analysis of the mesons from the reaction $\pi^{-}% p\to\pi^{+}\pi^{-}\pi^{-}\pi^{0}\pi^{0}p$ has been performed. The data show $b_{1}\pi$ decay of the spin-exotic states $\pi_{1}(1600)$ and \ $\pi_{1}(2000)$. Three isovector $2^{-+}$ states were seen in the $\omega\rho^{-}$ decay channel. In addition to the well known $\pi_{2}(1670)$, signals were also observed for $\pi_{2}(1880)$ and $\pi_{2}(1970)$.
