  We analyse the mass spectrum of the Constrained Minimal Supersymmetric
Standard Model at the low tan beta fixed point. We find that the model only
satisfies experimental and dark matter bounds in regions where the vacuum is
meta-stable -- ie where it violates `unbounded from below' (UFB) bounds. Adding
a small amount of R-parity violation solves these problems but the absolute
upper bound on the lowest higgs mass m_{h^0}<97 GeV remains. We present the
predicted sparticle mass spectrum as a function of the gluino mass m_g.
