The Equivalence Theorem is commonly used to calculate perturbatively
amplitudes involving gauge bosons at energy scales higher than gauge
boson masses. However, when the scalar sector is strongly interacting
the theory is non-perturbative. We show that the Equivalence Theorem
holds in the large N limit at next-to-leading order by calculating the
decay widths h -> W^{+}W^{-} and h->pi^{+}pi^{-}. We also show,
in the same scheme of calculations, that unitarity is fulfilled for the
process h->pi^{+}pi^{-}.
