Rising stars Angus Beith and Liam Smith have both pledged their immediate futures to the club.
The duo - graduates of the Hearts Football Academy - have signed contract extensions until 2016, keeping them in Gorgie for another two years.
18-year old Angus featured in several first-team squads last season, making his top team bow in the 0-0 friendly match against Wolfbsurg in November 2013.
Full-back Liam, also 18, captained last year's U20s to the Final of the Scottish Youth Cup, where the Wee Jambos agonisingly lost out on penalties to Rangers.
Both players have found themselves in head coach Robbie Neilson's pre-season plans this campaign as they look impress in the U20s and challenge for spots in the first-team squad.
