It is proposed that supergravity unified models contain in addition to the hidden and the visible sectors, a third sector which contains exotic matter with couplings to the fields of both the visible and the hidden sectors. After spontaneous breaking of supersymmetry exotic matter becomes superheavy and its elimination leads to quark-lepton textures at the GUT scale with a hierarchy in powers of $M_G/M_P$.Textures in the Higgs triplet sector are also computed and it is shown that they modify predictions of proton decay in unified models.
