A model of interacting electrons living on two chains coupled by a transverse hopping t ⊥ is solved exactly by a bosonization technique. It is shown that t ⊥ does modify the shapeof the Fermi surface also in the presence of interaction, although charge and spin excitations keep different velocities up, u σ
