  I present a general exclusion bound for the Higgs in fourth generation
scenarios with a general lepton sector. Recent Higgs searches in fourth
generation scenarios rule out the entire Higgs mass region between 120 and 600
GeV. That such a large range of Higgs masses are excluded is due to the
presence of extra heavy flavors of quarks, which substantially increase Higgs
production from gluon fusion over the Standard Model rate. However, if heavy
fourth generation neutrinos are less than half of the Higgs mass, they can
dominate the Higgs decay branching fraction, overtaking the standard Higgs to
WW* decay rate. The Higgs mass exclusion in a fourth generation scenario is
shown most generally to be 155-600 GeV, and is highly dependent on the fourth
generation neutrino mixing parameter.
