The results of the Partial Wave Analysis of the reaction {pi}{sup {minus}}p{r_arrow}{eta}{pi}{sup +}{pi}{sup {minus}}{pi}{sup {minus}}p are presented. The analysis included study of f{sub 1}(1285){pi}{sup {minus}}, a{sub 0}(980){rho}(770), a{sub 2}(1320){eta} and also {eta}{sup {prime}}(985){pi}{sup {minus}} channels. The dominant partial waves in f{sub 1}(1285){pi}{sup {minus}} system are J{sup PC}=1{sup ++}, 1{sup {minus}+} exotic wave and 2{sup {minus}+}. The {eta}{sup {prime}}(985){pi}{sup {minus}} system is dominated by exotic J{sup PC}=1{sup {minus}+} wave, peaking near 1.6 GeV. The intensity of 2{sup ++}{eta}{sup {prime}}{pi}{sup {minus}} wave shows clearly the a{sub 2}(1320) signal, and also some bump near 1.75 GeV. Both f{sub 1}(1285){pi}{sup {minus}} and {eta}{sup {prime}}{pi}{sup {minus}} systems show the small signal from a{sub 4}(2030) meson in 4{sup ++} wave. The mass-dependent analysis is in progress. {copyright} {ital 1998 American Institute of Physics.}
