Let E be a quadratic extension of a nonarchimedean filed F, and GU(2,2) be the quasi-split unitary similitude group attached to E/F. Let $\pi$ be an irreducible, admissible, generic representation of GU(2, 2), and $L(s,\pi)$ be its twisted exterior square L-function. We show $L(s,\pi)$ has a functional equation, and $\pi$ has a Whittaker function W fixed by an arithmetic subgoup determined by the epsilon factor of the functional equation. The subspace fixed by this subgroup is one-dimensional, and a zeta integral of W is equal to $L(s,\pi)$, so, we call W the new form of $\pi$.
