In 2012, Sullivan is scheduled to earn a $3 million base salary, which is fully guaranteed (skill, injury and cap), Sullivan is due to earn $3.15 million in base salary in 2013, of which, $2 million is fully guaranteed. The final three years of the deal call for base salaries of $3.65 million (2014) and $4.65 million (2015 and 2016) and there are unspecified base salary escalators and $100,000 workout bonuses from 2013-16.
