  We study N=2 spontaneous supersymmetry breaking at two different scales with
matter fields in hypermultiplets charged under the gauge group that should
involve at least two U(1) factors. Off-shell analysis is possible in the dual
single-tensor formulation of the hypermultiplets. Massless fermions can
naturally arise from pseudo-real representations of the gauge group that allow
a reformulation of the problem of chirality in N=2 theories. The above
properties are necessary ingredients towards constructing viable extensions of
the Standard Model based on N=2 supersymmetry.
