The newly structured extension will have Riley under contract through 2012 with rollover provisions.

The 53-year-old Riley will make a guaranteed base salary of $850,000 in the first year of the contract. It would rise incrementally to $1.1 million in the final year.

Riley's contract also stipulates that a year will be added for every season the team participates in a bowl game. A bowl game appearance will also trigger bonuses for Riley's assistant coaches.

Riley will enter his seventh year as the head coach at Oregon State this fall.
