Exeter have agreed contract extensions with Will Chudley, Matt Jess and Don Armand.
Winger Jess, 30, and scrum-half Chudley have signed until the summer of 2018 and back-row Armand until 2017.
"All three are players that have shown really good form over both this season and last season," said head coach Rob Baxter.
The trio follow and the in signing new deals.
Jess joined Exeter in 2008 from Launceston and has been with the club as they progressed from the Championship to the Premiership, scoring 51 tries in 162 appearances for the Chiefs.
Chudley, 26, arrived from Newcastle Falcons following their relegation from the top flight in 2012 while Armand, 26, moved to Sandy Park from South African Super rugby side Stormers in July 2013.
"Keeping a group of players together who have been playing well is probably at the core of what we have done over quite a long time," Baxter said.
"Yes, we have added players and some have moved on, but our playing group has remained relatively together.
"This is Don's second contract, Jessy's third or fourth, and Will Chudley's second too. These are guys that have come in, done well and now they are going to get more time.
"I am expecting that they will keep performing well and keep getting better the more time they spend with us."
