Edinburgh have secured young stand-offs Harry Leonard and Gregor Hunter on two-year contract extensions.
Leonard, 19, and Hunter, 20, have each played seven times for Michael Bradley's side and are now tied to the Murrayfield club until 2014.
Bradley said: "Both players have already displayed a dynamism and flair to create opportunities for the players around them as well as the composure to control games with territorial and positional awareness, well beyond their years."
Brighton-born Leonard, who qualifies for Scotland through his mother, was brought up through the Scottish Rugby exile programme and spent 18 weeks in New Zealand on a scholarship after a spell at Boroughmuir.
The Scotland Under-20 captain turned in a man-of-the-match display when Edinburgh secured their first away win of the season against Treviso.
He said: "Since returning from New Zealand I've become a real part of the Edinburgh Rugby squad and have had some invaluable experience of both the RaboDirect PRO12 and the Heineken Cup - with our away win over London Irish a real stand-out career highlight.
"I'm really happy to be staying on at this club. Murrayfield is a fantastic place to train and play, with the coaching team providing a huge amount of support for every player."
Hunter has been part of the Edinburgh squad since 2010, having come through the ranks at Gala.
Hunter represented Scotland at several age levels and recovered from the groin injury that forced him to miss most of last season to score the winning try in the 19-14 win over Connacht this term.
He said: "I've really enjoyed this season. It's been really good to get some game time. Michael (Bradley) isn't afraid to give the young players a shot and I think a lot of us have done well because of the confidence shown in our ability."
