We study the effects on the vector-boson parameters due to a heavy scalar singlet interacting strongly with the Higgs sector of the standard model. The one-loop-induced effects due to the additional scalar are not suppressed by inverse powers of its mass. In the limit that the singlet-Higgs coupling becomes much larger than the Higgs self-coupling, the 4W vertex differs from that in the standard model. In this limit the leading corrections are not related to the divergences of the gauged nonlinear model.
