Let $\mathcal{F}=(X,\omega,f,B)$ be a generic-singular fibration. Assume that $\Sigma=\Crit(f)$ is non-degenerate. Then there is a $T^{2}$ invariant neighborhood $U\subseteq X$ of $\Sigma$ and a commutative diagram

$$\begin{CD}U@>{\Psi}>{}>D^{4}\times D^{1}\times S^{1}\\ @V{f|_{U}}V{}V@V{}V{F}V\\ B@>{\psi}>{}>D^{2}\times D^{1}\end{CD}$$

(16)

where coordinates $(x,y)$ on $D^{4}$ and $(r,\theta)$ on $D^{1}\times S^{1}$ define standard symplectic coordinates, the map $\Psi$ is a symplectomorphism, $\psi$ is a diffeomorphism sending $\Delta$ to $\{0\}\times D^{1}$ and $F$ is given by (14). Furthermore $\Psi$ can be taken to be $T^{n-1}$ equivariant.
