Ok, here's the situation:
 
Player 1 from Team A takes a minor penalty at 13:00.
Player 1 from Team B takes a minor penalty at 13:30.
Player 2 from Team B takes a minor penalty at 14:30.
 
Team A (now on a powerplay) scores at 14:55.
 
Remaining penalty times are:
 
Team A:  0:05
Team B:  0:35
         1:35
 
The question:  Which of B's penalties is wiped out?  If possible, I would
love a specific reference to the applicable rule in the NC$$ rulebook.

P.S.  No, this is not a hypothetical question.  This scenario happened in
      Friday's UNH-Providence game.
