N2 - The effect of the pion exchange on the line shape of near threshold bottomoniumlike resonances decaying into an S wave pair of B(∗) mesons is considered. It is pointed out that this effect, parametrically enhanced by the heavy meson mass, can be of a practical significance in determining the parameters of the bottomoniumlike resonances such as the known Zb(10610) and Zb(10650) states.
