We investigate compactifications of M-theory from 11→ 5→ 4 dimensions and discuss geometrical properties of 4-d moduli fields related to the structure of 5-d theory. We study supersymmetry breaking by compactification of the fifth dimension and find that an universal superpotential is generated for the axion-dilaton superfield S. The resulting theory has a vacuum with <S>=1, zero cosmological constant and a gravitino mass depending on the fifth radius as m3/2 ∼ R5-2/MPl. We discuss phenomenological aspects of this scenario, mainly the string unification and the decompactification problem.
