Explanation of Responses:

1. Each Restricted Stock Unit represents the right to receive one share of the Issuer's common stock. The reporting person settled 42% of his RSUs for cash and 58% of his RSUs for Common Stock of the Issuer.

2. On February 18, 2016, 10,667 RSUs were granted to the reporting person. 2,667 of these RSUs vested on February 18, 2017 and another 2,667 RSUs vested on February 18, 2018. The remaining 5,333 RSUs will vest, if at all, based on the formula in footnote 6 of Form 4 filed by the reporting person for the transaction date of February 19, 2017, which takes into account the Issuer's achievement of budgeted Adjusted EBITDA and the total return to the Issuer's shareholders in comparison to the total shareholder return of the Issuer's peer group of public companies.

3. On February 18, 2016, 5,354 RSUs were granted to the reporting person. 1,785 of these RSUs vested on February 18, 2017 and another 1,785 RSUs vested on February 18, 2018. The remaining 1,784 RSUs will vest on February 18, 2019.

4. Each Restricted Stock Unit represents the right to receive one share of the Issuer's common stock.

5. On February 19, 2015, 10,667 RSUs were granted to the reporting person. 2,667 of these RSUs vested on February 19, 2016, and another 2,667 of these RSUs vested on February 19, 2017. The vesting of the remaining 5,333 RSUs were subject to the formula in footnote 6 of the Form 4 filed by the reporting person for the transaction date of February 19, 2017, which takes into account the Issuer's achievement of budgeted Adjusted EBITDA and the total return to the Issuer's shareholders in comparison to the total shareholder return of the Issuer's peer group of public companies. On February 19, 2018, the Issuer determined that the performance conditions were only partially satisfied and, as a result, 3,671 of the RSUs of the original grant was forfeited, while 1,662 vested.
