XP penalty for multiclassing

[Brutoss]

Does anybody know if Neverwinter Nights imposes an XP penalty for multiclassed characters? I know there is a penalty in the core D&D 3.0 rules but can't find anything about it for Neverwinter Nights.

I have noticed that when my character is lying there mortally wounded whilst the battle continues around him, that I get credited with XP when my companions defeat monsters, then I get docked a larger amount of XP than I got credited, with a notice that I can't receive XP when dead.

Thanks for any help.

Yes, it does.

20% of any class not within one level of the highest class level, barring favored classes or PrCs.
