Redesign of a current powerpoint presentation

I have an attached presentation - which was done donkeys years ago. I'd just like it to look a tiny bit more current. I'm not asking for a design job as the audience reading it aren't too bothered. But I'd like it to look a tiny bit more professional. Lots of colour isn't important as if the slides are printed off too much ink will be used.

So looking for a simple but professional amended copy. The wording is to stay exactly the same.
