We calculate the contribution to the curvature perturbation, that is generated while the waterfall field grows exponentially (which can occur only if the waterfall field mass is $m\gg H$). We consider the upper bound on its spectrum coming from constraints on the abundance of primordial black holes, taking account of possible non-gaussianity. The constraint is satisfied, but extrapolation of our result to the regime $m\sim H$ suggests that the constraint might not be satisfied there.
