  We consider a holomorphic 1-form $\omega$ with an isolated zero on an
isolated complete intersection singularity $(V,0)$. We construct quadratic
forms on an algebra of functions and on a module of differential forms
associated to the pair $(V,\omega)$. They generalize the
Eisenbud-Levine-Khimshiashvili quadratic form defined for a smooth $V$.
