  We study the impact that a heavy generation of vector-like leptons can have
on the value of the electric dipole moment of the electron, and the rates for
the flavor violating processes mu --> e gamma and mu --> 3e. The smallness of
the charged lepton masses suggests that at least some of the Yukawa coupling
constants of the vector-like leptons to the ordinary leptons or amongst
themselves are small, but even with such small couplings experiments trying to
detect these quantities are sensitive to extra generation lepton masses up to
about 100 TeV.
