Northern Ireland U21 midfielder Eunan O'Kane has put pen to paper on a two-year contract extension at Torquay.
The new deal will take the 21-year-old's current deal at the club through until summer 2014.
Gulls manager Martin Ling said: "When I came here, I was told an awful lot of good things about Eunan O'Kane.
"He has done all the things people have said he could. He is a tremendous player and a real asset, so getting him signed for the next three seasons is a big coup for this football club.
"I feel he is better than League Two and we've convinced Eunan there is a future for him to display his talents here. When I spoke to him in July, we agreed to reconvene in September, which is what we've done. We know an awful lot more about each other and we obviously feel it is a marriage that works perfectly well for both parties.
"He wanted to see what I was about and how I was going to play the game. He is a certain type of footballer, who needs a manager to play to his strengths."
