  Confined excitonic complexes in two dimensions, consisting of N_e electrons
and N_h holes, are studied by means of Bethe-Goldstone equations. Systems with
up to twelve pairs, and asymmetric configurations with N_e \ne N_h are
considered. The weak confinement regime gives indication of weak binding or
even unbinding in the triexciton and the four-exciton system, and binding in
the higher complexes.
