In this talk I look into three different topics, addressing first the possibility that the Theta(+) is a bound state of K pi N, exploiting the results of this study to find out the contribution of two meson and one baryon components in the baryon antidecuplet and in the third place I present results on a new resonant exotic baryonic state which appears as dynamically generated by the Weinberg Tomozawa Delta K interaction.
