Rob Taylor, Ben Raine and Jigar Naik are among eight players to sign new contracts with Leicestershire.
The Foxes have tied down Taylor, who is second in the county's first-class bowling averages this season and has also hit three half-centuries.
Raine has also weighed in with his share of wickets this season, while Naik impressed with his off-spin in limited-overs competition and with the bat in the LV= County Championship.
Left-arm paceman Atif Sheikh, who posed problems for India’s touring team at Grace Road, joins Taylor, Naik, batsman Tom Wells and young spinner Rob Sayer in signing two-year contract extensions.
Raine, slow left-armer James Sykes and batsman Lewis Hill have all joined for one additional year.
Director of cricket Phil Whitticase said: "We are working very hard on building our squad for the future, and we are thrilled that these eight players have committed their futures to us.
"There have been more offers made to players, and we are hopeful to be in a position to announce more good news in the near future."
