100000EXP bonus is not 100000EXP obtained. You'd have to add whatever EXP you obtained plus the percentage of that which you won as a bonus to get an accurate number.

Example: Tier II Company Scrolls give you a 50% bonus, up to 9000. That means that out of the next 27000 EXP you get (excluding other bonuses you may have on), 9000 of that was a bonus.
