  We show that LEPII will either discover charginos and neutralinos, or enable
a very stringent upper limit to be placed on $\tan \beta$ as a function of the
gluino mass. The only assumption we make is the existence of some unified model
which breaks down to the minimal supersymmetric standard model below the
unification scale. In such a framework we discuss how the discovery of a
chargino at LEPII and the measurement of its mass and production cross-section,
together with the measurement of the mass of the lightest neutralino, would
enable the gluino mass, $\tan \beta$ and $\mu$ to be predicted, up to a
possible ambiguity in the sign of $\mu$ which we discuss.
