Exeter are hoping the signing will boost attendance:
"It would be nice to see 5,000 fans there tomorrow night," joint vice-chairman Mike Lewis told the Exeter Express & Echo.
"By giving us their support, that will allow us to keep on signing better quality players.
We worked really hard all day on Friday to bring Lee to the club, talking to his agent and talking to Lee four or five times. We finally cracked a deal on a match-by-match basis even though he was also rather keen on going abroad."
