We continue our exploration of various approaches to integration of representations from a Lie algebra Lie (G) to an algebraic group G 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 G-stability.
