If a note holder chooses to present their notes for conversion during a future quarter prior to the first put/call date in July 2012, they would receive cash up to $1,000 for each 2 3/8% Note plus Company common stock for any excess valuation over $1,000 using the conversion rate of the 2 3/8% Notes of 31.496 multiplied by the Company’s average common stock price over a ten trading day period following presentation of the 2 3/8% Notes for conversion. The future convertibility and resultant balance sheet classification of this liability will be monitored at each quarterly reporting date and will be analyzed dependent upon market prices of the Company’s common stock during the prescribed measurement periods. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     The following table presents the carrying amount of our 2 3/8% Notes in our condensed consolidated balance sheets (in thousands): </div> <div align="center"> <table style="font-size: 10pt; text-align: left" cellspacing="0" border="0" cellpadding="0" width="100%">  <tr valign="bottom"> <td width="76%"> </td> <td width="5%"> </td> <td width="1%"> </td> <td width="5%"> </td> <td width="1%"> </td> <td width="5%"> </td> <td width="1%"> </td> <td width="5%"> </td> <td width="1%"> </td> </tr> <tr style="font-size: 8pt" valign="bottom"> <td> </td> <td> </td> <td nowrap="nowrap" align="center" colspan="2" style="border-bottom: 1px solid #000000"><b>June 30, 2010</b></td> <td> </td> <td> </td> <td nowrap="nowrap" align="center" colspan="2" style="border-bottom: 1px solid #000000"><b>December 31, 2009</b></td> <td> </td> </tr>   <tr valign="bottom" style="background: #cceeff"> <td> <div style="margin-left:15px; text-indent:-15px">Carrying amount of the equity component in additional paid-in capital </div></td> <td> </td> <td align="left">$</td> <td align="right">28,449</td> <td> </td> <td> </td> <td align="left">$</td> <td align="right">28,449</td> <td> </td> </tr> <tr valign="bottom"> <td> <div style="margin-left:15px; text-indent:-15px">  </div></td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> </tr> <tr valign="bottom"> <td> <div style="margin-left:15px; text-indent:-15px">Principal amount of the liability component </div></td> <td> </td> <td align="left">$</td> <td align="right">175,000</td> <td> </td> <td> </td> <td align="left">$</td> <td align="right">175,000</td> <td> </td> </tr> <tr valign="bottom" style="background: #cceeff"> <td> <div style="margin-left:30px; text-indent:-15px">Less: unamortized discount </div></td> <td> </td> <td> </td> <td align="right">15,581</td> <td> </td> <td> </td> <td> </td> <td align="right">19,141</td> <td> </td> </tr> <tr style="font-size: 1px"> <td> <div style="margin-left:15px; text-indent:-15px">  </div></td> <td> </td> <td nowrap="nowrap" colspan="2" align="right" style="border-top: 1px solid #000000"> </td> <td> </td> <td> </td> <td nowrap="nowrap" colspan="2" align="right" style="border-top: 1px solid #000000"> </td> <td> </td> </tr> <tr valign="bottom"> <td> <div style="margin-left:30px; text-indent:-15px">Net carrying amount of the liability component </div></td> <td> </td> <td align="left">$</td> <td align="right">159,419</td> <td> </td> <td> </td> <td align="left">$</td> <td align="right">155,859</td> <td> </td> </tr> <tr style="font-size: 1px"> <td> <div style="margin-left:15px; text-indent:-15px">  </div></td> <td> </td> <td nowrap="nowrap" colspan="2" align="right" style="border-top: 3px double #000000"> </td> <td> </td> <td> </td> <td nowrap="nowrap" colspan="2" align="right" style="border-top: 3px double #000000"> </td> <td> </td> </tr>  </table> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     The effective interest rate is 7.17% for our 2 3/8% Notes.
