Exeter Chiefs duo Tomas Francis and Sam Hill have signed new deals with the club until 2017 and 2018 respectively.
Tight-head prop Francis joined the Chiefs from Championship side London Scottish last summer.
Meanwhile, centre Hill is a product of Exeter's youth academy.
"Recruitment is one of those things that is ongoing all the time, it never really stops," coach Rob Baxter told the club's official website.
"We will be working on contract extensions now going forwards and start talking to some of our other players who will be out of contract in the next year or two. It is always nice to get players to start committing to longer-term contracts though. It makes it a lot more comfortable."
Exeter start the new Aviva Premiership season with a trip to Bath on October 17.
