Haydn Hollis, Greg Tempest, Curtis Thompson and Tyrell Waite have agreed new deals with Notts County.
Hollis who has made six first team appearances this season has agreed a three-year contract, while the others have all put pen to paper on two-year deals.
20-year-old defender Hollis and midfielders Tempest and Thompson, both 19, have come through the club’s youth system while 18-year-old striker Waite joined the club from Ilkeston last year after a successful trial period.
The quartet are the first out-of-contract players to commit to the club this summer.
