In the present paper, we find conditions that change a neat high subgroup into a pure-high subgroup and a neat subgroup, to a pure subgroup. It is shown that a neat-high extension can be transformed into a pure-high extension and a neat extension, to a pure extension. Furthermore, splitting conditions for a neat exact sequence are obtained.
