While partying, all living party members on the map will gain experience when a monster is killed. The amount of experience gained starts at the total exp amount for the monster, and decreases with the number of party members that did not contribute to the monster's death. A player is seen as contributing to a kill if they have either dealt or received damage at some point to the target.

The chart on the right shows the amount of experience you earn when a party member kills a monster, based on the number of non-contributing players. If all party members have contributed, all players will receive 100% of the monster's exp value.
