Clemson coach Oliver Purnell has agreed to a two-year contract extension that will keep him with the Tigers through 2016 and keep him the school's highest paid coach.

While the deal hasn't been signed, Purnell and athletic director Terry Don Phillips have signed a memoradum of understanding dated June 1 that outlines the improved package.

Purnell's base salary jumped $50,000 a year to $275,000. His supplemental income improved to $1.075 million each year, up from $775,000 guaranteed in a two-year extension agreed to in 2008.

Purnell will also receive deferred compensation of $250,000 a year in 2015 and 2016, money the coach would receive unless he left the school voluntarily or was fired for cause.

The Tigers coach would owe the school $250,000 if he left after April 30 for another Division I head coaching job. That payback amount would increase by $250,000 each year until reaching $1.5 million should Purnell depart for a Division I job after April 30, 2015.

The new agreement moves Purnell further out front as the highest paid coach in the Tigers' athletic department.

Since he arrived in 2003-04, Purnell had been behind football's Tommy Bowden in the salary department. Bowden entered last fall with a contract that guaranteed him at least $1.83 million at the start of last season. However, Bowden left in midseason with the Tigers floundering.
