Managing director Derek Llambias said Newcastle want continuity to match English football's top clubs.
"If you look at clubs like Manchester United and Arsenal, Sir Alex Ferguson and Arsene Wenger have shown that stability gives you the best platform to achieve success and that is the model we wish to emulate here," he commented.
"We're looking to build on the success we had last season and these new contracts are aimed at keeping the club progressing on and off the pitch, as we have done since returning to the Premier League in 2010."
