  We consider SUSY SO(10) models in which SUSY breaking occurs via an F-term
which does not transform as an SO(10) singlet. This results in non-universal
GUT-scale gaugino masses leading to a different pattern of sparticle masses
from what is expected in the minimal supergravity model (mSUGRA). We study
three breaking chains of SO(10) down to the standard model through
SU(4)$\timesSU(2)\times$SU(2), SU(2)$\times$SO(7) and `flipped' SU(5) achieved
by the representations 54 and 210 which appear in the symmetric product of two
SO(10) adjoints. We examine the phenomenological implications of the different
boundary conditions corresponding to the different breaking chains and present
the sparticle spectrum.
