Workout:

With a constantly running clock, perform 1 pull-up the first minute, 2 the second minute, 3 the third, and so on until you cannot perform the required number of pull-ups for the minute that you are on. If you come up short of 10 minutes, start back at one pull-up the minute following your failed set (so if you made it to only 4 pull-ups in the 5th minute, you'll do 1 on the sixth minute, 2 on the seventh, etc. until you reach your second failed set). You can break up the reps into as many sets as needed per minute.
