  Let $(X,D)$ be a smooth log pair over $\mathbb{C}$ such that the complement
$U := X \setminus D$ carries a maximally varied family of polarized manifolds.
We prove a version of second main theorem on $(X,D)$ by using the Viehweg-Zuo
construction of the family and McQuillan's tautological inequality. As an
application, we generalize a classical result of Nadel about the distribution
of entire curves in the (compactified) base space of polarized families.
