Exit relay

Definition
"An exit relay is the final relay that Tor traffic passes through before it reaches its destination. Exit relays advertise their presence to the entire Tor network, so they can be used by any Tor users. Because Tor traffic exits through these relays, the IP address of the exit relay is interpreted as the source of the traffic. If a malicious user employs the Tor network to do something that might be objectionable or illegal, the exit relay may take the blame. People who run exit relays should be prepared to deal with complaints, copyright takedown notices, and the possibility that their servers may attract the attention of law enforcement agencies. If you aren't prepared to deal with potential issues like this, you might want to run a middle relay instead. We recommend that an exit relay should be operated on a dedicated machine in a hosting facility that is aware that the server is running an exit node."
