Smid's Contract

There is one question I have never been able to find an answer for and I was reminded of it when I was looking at Ladislav Smid's waiver eligibility: How is Smid still on his entry-level contract? He played the 2005-06 season for Anaheim's AHL affiliate and then 06-07 and 07-08 with the Oilers. The Ducks announced that he was signed to a three-year entry-level contract in August of 2005. So how is he still under contract in 2008-09?
