Sussex cricket manager Mark Robinson has confirmed the club have offered new deals to four out-of-contract players.
Bowlers Will Beer and Lewis Hatchett, all-rounder Steffan Piolet and batsman Luke Wells are all in negotiations.
"We try and do a lot of our dealings as late as we can, especially with our own players," Robinson told BBC Sussex.
"It is just a case of sitting down with the people who represent them to make sure everybody is happy before we can announce any signings."
Opener Wells, 23, only missed one match in the County Championship last season, scoring 942 first-class runs at an average of 36.32.
Spinner Beer, fast bowler Hatchett and Piolet were all regulars in one-day competition for Sussex in 2014.
Leg-break bowler Beer, 26, stood out with 13 wickets and 98 runs in the T20 Blast and a further seven scalps and 99 runs in the One-Day Cup.
"We are in the same situation with all those players, just making sure everything is in place that they want so we can announce them as Sussex players for the future," Robinson added.
