|Luke Conlan becomes a Turf Moor professional|
Left back Conlan, from Northern Ireland and New Zealander Howieson are both currently in the first year of their scholarships with the club but that's been replaced with these new deals for the next two seasons.
In confirming the news, manager Eddie Howe said: "We believe it's vitally important that we produce our own players and this is another important step in that direction. Cameron and Luke have both done very well this season and deserve the contracts they have been given.
"We believe both are very promising players who will develop further from working more regularly with the first-team squad. It has been an excellent season at youth level and we believe there are few who are good enough to make the step up."
Both players have been in outstanding form this season with the youth team and only last week Howieson was warming up with the first team ahead of the league game against West Ham United.
They have also both featured for their respective countries at youth level and will now be looking to progress at Turf Moor.
Howe has already said that some of this season's youth teams will figure with the first team this season and Conlan and Howieson now join Steven Hewitt in having professional deals confirmed.
Other members of the squad are expected to sign professional deals with the club with Tom Anderson believed to be close to signing his first professional deal.
