The predicted value of the higgs mass mH is analyzed assuming
the existence of the fourth generation of leptons (N, E) and
quarks (U, D).
The steep and flat directions are found in the
five-dimensional parameter space: mH, mU, mD, mN,
mE. The LEPTOP fit of the precision electroweak data is
compatible (in particular) with GeV, GeV, GeV, GeV, and GeV. The
quality of fits drastically improves when the data on b- and c-quark
asymmetries and new NuTeV data on deep inelastic scattering are ignored.
