I am in a guild of just myself and I have only the new xp buff (at 3%) and have found that this buff is not removed on death but it is dispellable. (a quick trip to invaders was enough to reproduce this)
This is interesting. There were dispelling casters in the quests I ran before my xp buff was gone. So this is very possible.
EDIT: Just did the same test. Yes, xp bufft gets removed by at least beholder dispel beam.

DDO: If a problem cannot be solved by the application of DPS, you're not applying enough.
