Narrative:
Captain had a vmo (max operating speed) exceedance after leveling off from a climb in a clean configuration at 8;000 ft MSL. The alarm and I notified him and he corrected by reducing power and slowing down. The filed altitude for the flight was 7;000 [feet] but due to terrain we had to climb to 8;000 [feet]. The change to the flight plan and what we briefed on the ground caused distractions between mfd display; ATC instructions/communications; [and] flying the plane and aircraft control. This was during leg 5 of a 5 leg day and we were in our 12th duty hour.the cause of this exceedance I believe is due to the lack of experience the captain has with this aircraft and the challenging operations at [company]. The lessons I learned from this is to be more vigilant with monitoring the pilot flying during high workload and transitions. Example; leveling off from a climb.
