Shares of restricted common stock subject to the Program were granted in 2008, 2009 and 2010. Vesting of these shares is contingent, begins upon satisfaction of specified thresholds of $38.00 and $46.00 for the market price per share of Mariner’s common stock, and continues in installments over five to seven years thereafter, assuming, in most instances, continued employment by Mariner. The fair value of restricted stock grants made under the Program is estimated using a Monte Carlo simulation. For the three months and six months ended June 30, 2010, stock-based compensation expense related to these restricted stock grants totaled $2.1 million and $4.4 million, respectively. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     Weighted average fair values and valuation assumptions used to value Program grants for the quarter ended June 30, 2010 are as follows: </div> <div align="center"> <table style="font-size: 10pt; text-align: left" cellspacing="0" border="0" cellpadding="0" width="100%">  <tr valign="bottom"> <td width="88%"> </td> <td width="5%"> </td> <td width="3%"> </td> <td width="1%"> </td> <td width="3%"> </td> </tr> <tr style="font-size: 8pt" valign="bottom"> <td> </td> <td> </td> <td nowrap="nowrap" align="center" colspan="3"><b>Quarter Ended</b></td> </tr> <tr style="font-size: 8pt" valign="bottom"> <td> </td> <td> </td> <td nowrap="nowrap" align="center" colspan="3" style="border-bottom: 1px solid #000000"><b>June 30, 2010</b></td> </tr>   <tr valign="bottom" style="background: #cceeff"> <td> <div style="margin-left:15px; text-indent:-15px">Weighted average fair value of grants </div></td> <td> </td> <td align="right">$</td> <td align="right">16.02</td> <td> </td> </tr> <tr valign="bottom"> <td> <div style="margin-left:15px; text-indent:-15px">Expected volatility </div></td> <td> </td> <td nowrap="nowrap" align="right"> </td> <td align="right">60.24</td> <td nowrap="nowrap">%</td> </tr> <tr valign="bottom" style="background: #cceeff"> <td> <div style="margin-left:15px; text-indent:-15px">Risk-free interest rate </div></td> <td> </td> <td nowrap="nowrap" align="right"> </td> <td align="right">4.20</td> <td nowrap="nowrap">%</td> </tr> <tr valign="bottom"> <td> <div style="margin-left:15px; text-indent:-15px">Dividend yield </div></td> <td> </td> <td nowrap="nowrap" align="right"> </td> <td align="right">0.00</td> <td nowrap="nowrap">%</td> </tr> <tr valign="bottom" style="background: #cceeff"> <td> <div style="margin-left:15px; text-indent:-15px">Expected life </div></td> <td> </td> <td colspan="2" nowrap="nowrap" align="right">10 years</td> <td> </td> </tr>  </table> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     Expected volatility is calculated based on the average historical stock price volatility of Mariner and a peer group as of June 30, 2010.
