[1] During the years ended December 31, 2013 and December 31, 2012, the 341 days ended December 31, 2011 and the 24 days ended January 24, 2011, the weighted average grant date fair value of stock options granted was $1.5 million, $0.7 million, $0.1 million and $8.1 million, respectively. For purposes of determining compensation expense, the grant date fair value per share of the stock options was estimated using the Black-Scholes option pricing model which requires the use of various assumptions including the expected life of the option, expected dividend rate, expected volatility and risk-free interest rate. Key assumptions used for determining the fair value of stock options granted were as follows: Predecessor Company Year EndedDecember 31, 2013 Year EndedDecember 31, 2012 Three HundredForty-OneDays EndedDecember 31, 2011 Twenty-FourDays EndedJanuary 24, 2011 Expected life (1)5.5 - 6 years 5.75 - 6 years 10 years 5.75 years Expected dividend (2)— — — — Expected volatility (3)45% 45% 45% 45% Risk-free interest rate (4)0.77% - 1.92% 0.82% - 1.21% 2.29% & 3.17% 2.37%

[2] During the years ended December 31, 2013 and 2012, the total intrinsic value of stock options that were exercised was negligible.

[3] Based upon a fair market value of the common stock as of December 31, 2013 of $11.31 per share, the stock options that are exercisable have an aggregate intrinsic value (equal to the value of in-the-money stock options above their respective exercise price) of $1.0 million.

[4] Based upon a fair market value of the common stock as of December 31, 2013 of $11.31 per share, the stock options that have vested and are expected to vest have an aggregate intrinsic value (equal to the value of in-the-money stock options above their respective exercise price) of $2.5 million.

[5] Except for the restricted stock awards granted on the Effective Date, the grant date fair value per share of the restricted stock awards under the Long Term Incentive Plan is calculated as the fair market value per share of the common stock on the date of grant. The grant date fair value per share of the restricted stock awarded on the Effective Date is equal to the fair value per share of the Company's common stock calculated in conjunction with fresh start accounting. During the year ended December 31, 2013, the year ended December 31, 2012, the 341 days ended December 31, 2011 and the 24 days ended January 24, 2011, the weighted average grant date fair value of restricted stock awards granted was $1.7 million, $0.2 million, $0.2 million and $10.2 million, respectively

[6] ased upon the respective grant date fair value, the aggregate fair value of restricted stock which vested during the year ended December 31, 2013, the year ended December 31, 2012, the 341 days ended December 31, 2011 and the 24 days ended January 24, 2011 was $2.4 million, $2.1 million, $0.1 million and $3.5 million, respectively.
