Rangers have confirmed the signing of Dundee United striker Jon Daly.
St Mirren defenders Sean Kelly and Jason Naismith have signed new one-year contracts with the club.
Inverness goalkeeper Ryan Esson insists he does not want to leave to the club and hopes he will be offered a new contract.
Esson is one of 12 first-team players whose deals expire at the end of the season, and although his agent has held talks with manager Terry Butcher, nothing has yet been finalised.
"I want to stay," Esson told the Inverness Courier. "I like the direction that the club is going in.
"This season, we had a big turnover of players, but sometimes you have to do that. It's just the nature of football.
"We knew it was going to be difficult, but you have to take it on the chin.
"We are still in the SPL and we've done pretty well in most of the games that we've played.
"You can't really say that in any of the games we've played that we've had an absolute doing. All you can do is take the positives and move forward.
"This is my fourth year at Inverness and I'm happy here. The way the club is it's very much like a family and everyone makes you fell welcome. It's a nice environment to ply your trade.
"I enjoy working with the manager and the players, so hopefully we can get something sorted out."
Esson has made 140 appearances for Caley since joining on a free transfer from Hereford in 2008.
