Assuming that the exotic Theta(+) belongs to an antidecuplet representation with (1710) as nucleon partner, we derive effective Lagrangians that describe the decay of N(1710) into N pi pi with two pions in s- or p-wave. It is found that the self-energies for all members of the antidecuplet are attractive, and the larger strangeness particle is more bound. From two meson cloud, we obtain about 20% of the empirical mass splitting between states with different strangeness. %~
