  In this article we present a simple theoretical framework where the origin of
the mu-term and the matter-parity violating interactions of the minimal
supersymmetric standard model can be understood from the spontaneous breaking
of new Abelian gauge symmetries. In this context the masses of the Z' gauge
bosons, the M-parity violating scale and the mu-term are determined by the
supersymmetry breaking scale. The full spectrum of the theory is discussed in
detail. We investigate the predictions for the Higgs masses in detail showing
that it is possible to satisfy the LEP2 bounds even with sub-TeV squark masses.
The model predicts the existence of light colored fields, lepton and baryon
number violation, and new neutral gauge bosons at the Large Hadron Collider.
