Here we consider how the predictions of the model are modified by Planck scale-suppressed corrections. In the absence of Planck corrections the model is equivalent to a $\\phi^{4/3}$ chaotic inflation model. Planck corrections become important when the dimensionless coupling $\\xi$ of $|\\Phi|^{2}$ to the topological charge density of the strongly-coupled gauge sector $F \\tilde{F}$ satisfies $\\xi \\sim 1$.
