8. Stock-Based Compensation

     During the first six months of 2011, the Company awarded restricted stock units and performance-based restricted stock units to employees under the 2010 Equity and Incentive Plan (the "2011 grant"). Expense associated with the performance-based restricted stock units may increase or decrease due to changes in the probability of the Company achieving pre-established performance metrics. For the six months ended June 30, 2011, total stock-based compensation cost recognized was approximately $4,600 of which approximately $700 was related to the 2011 grant. As of June 30, 2011, total unrecognized compensation cost related to non-vested stock options, restricted stock units, and performance-based restricted stock units under the 2011 grant was approximately $5,700, to be recognized over the 2.5 year remaining vesting period of these awards.
