Abstract
We continue our exploration of various approaches to integration of representations from a Lie algebra to an algebraic group in positive characteristic. In the present paper we concentrate on an approach exploiting exponentials. This approach works well for over-restricted representations, introduced in this paper, and takes no note of -stability.
