Let $\mathcal{F}$ be a Lagrangian negative fibration. With the notation as in Definition 7.1, let $U_{0}=U-(D^{\prime}\cup\Delta_{\tau})$ and $X(U_{0},\mathscr{A}_{\tau})$ be the associated Lagrangian torus bundle. Then, if $\mathcal{F}$ has a smooth Lagrangian section, $\mathcal{F}_{0}$ is symplectically conjugate to $X(U_{0},\mathscr{A}_{\tau})$.
