Defender Vanderhyde and midfielder Lee, both 18, have appeared on the bench for Russell Slade's side in recent weeks and have now secured their first pro deals.
Slade told the club's website: "I'm pleased to see these lads come through, they are good characters and they've impressed us this season.
"Full credit to (youth boss) Andy Edwards for his part in their development, the youth team have had a very good season."
