Striker Warren Feeney is one of five players to be offered new contracts at League Two side Plymouth Argyle.
Northern Ireland international Feeney, 31, joined the Pilgrims in July 2011 and scored three goals in 30 matches.
Robbie Williams, Durrell Berry, Joe Lennox and Ollie Chenoweth have also been offered new deals at Home Park.
Luke Daley and Damien Johnson have been released, while on-loan Alex MacDonald, Paul Bignot, Juvhel Tsoumou and Ashley Hemmings return to their parent clubs.
Defenders Williams and Berry established themselves as regulars in the Plymouth team during the 2011-12 campaign, while Lennox made eight appearances in the second half of the season after a successful trial period.
Goalkeeper Chenoweth made his debut for the club at the end of April in Plymouth's 2-2 draw at Morecambe.
