  Given a complex germ $f$ near the point $\mathfrak{x}$ of the complex
manifold $X$, equipped with a factorization $f = f_{1} \cdots f_{r}$, we
consider the $\mathscr{D}_{X,\mathfrak{x}}[s_{1}, \dots, s_{r}]$-module
generated by $ F^{S} := f_{1}^{s_{1}} \cdots f_{r}^{s_{r}}$. We show for a
large class of germs that the annihilator of $F^{S}$ is generated by
derivations and this property does not depend on the chosen factorization of
$f$.
  We further study the relationship between the Bernstein-Sato variety attached
to $F$ and the cohomology support loci of $f$, via the
$\mathscr{D}_{X,\mathfrak{x}}$-map $\nabla_{A}$. This is related to
multiplication by $f$ on certain quotient modules. We show that for our class
of divisors the injectivity of $\nabla_{A}$ implies its surjectivity.
Restricting to reduced, free divisors, we also show the reverse, using the
theory of Lie-Rinehart algebras. In particular, we analyze the dual of
$\nabla_{A}$ using techniques pioneered by Narv\'aez-Macarro.
  As an application of our results we establish a conjecture of Budur in the
tame case: if $\text{V}(f)$ is a central, essential, indecomposable, and tame
hyperplane arrangement, then the Bernstein-Sato variety associated to $F$
contains a certain hyperplane. By the work of Budur, this verifies the
Topological Mulivariable Strong Monodromy Conjecture for tame arrangements.
Finally, in the reduced and free case, we characterize local systems outside
the cohomology support loci of $f$ near $\mathfrak{x}$ in terms of the
simplicity of modules derived from $F^{S}.$
