  We discuss the structure of the neutrino mass matrix as derived from a
nonuniversal electroweak gauge interaction model. We discuss two interesting
patterns of neutrino masses. The first pattern is hierarchal which fits the LMA
or LOW solutions of solar neutrino data. The second pattern gives rise to
inverted mass spectrum which fits the currently not preferred SMA solution. The
mechanism for generating a light sterile neutrino mass is interesting and is
briefly discussed.
