Actually, you did not answer his question. He asked if the -35% AP will apply if Exhaust is applied after he already started casting his ultimate.

My guess is yes, but I am not sure. I do think that AP gains/loses apply to dots, i.e. if you already have a dot on an enemy and you gain/lose AP, the dot becomes stronger/weaker. This may also apply to channeled abilities. That is if I'm not wrong about the dots :)
