  We determine the one point genus zero correlators of compactly supported
forms of a subcritical Stein filling whose first Chern class vanishes. This is
a step towards determining the full potential function of the filling. As an
application, we proved that if a K\"{a}hler manifold $M^{2n}$ admits a
subcritical polarization and $c_1$ vanishes in the subcritical complement, then
$M$ is uniruled.
