Exception rules? I'm not understanding the term?

The unaltered game does allow for play with less than five (though it typically isn't great play.) This expansion is more aimed for larger groups

I don't see why a game with 4 players shouldn't be possible with the expansion, but you will have to pick the area very carefully and the player - with my guess - just isn't going to be as good.
Maybe for 4, try Hitte, Crete, Illyria and Thrace. For 3, drop either Hitte or Thrace. For 2, forget it. Include enough land for 6 city sites per nation. Maybe at 3 & 4 the trade card mix needs to be tweaked as well. Maybe a single larger set?
