Narrative:
I was descending the aircraft intending to level at 10000 ft but captain initiated a conversation at about 10700 ft and ATC asked some questions. I found the airplane at 300 KTS at 9700 ft. Leveled and slowed as soon as possible. Contributing factor: poor sleep the night before. The contributing distrs were only minor.
