       In March 2010, we issued 7,446,250 common units in an
       underwritten public offering (including units issued upon the
       underwriters&amp;#8217; exercise of their option to purchase
       additional units). We used the net proceeds from the offering to
       repay a portion of the outstanding indebtedness under our Credit
       Facility, and we expect to use the increased borrowing capacity
       as needed for capital projects, acquisitions, hedging, working
       capital and general corporate purposes.

       Class&amp;#160;D units totaling 3,245,817 as of December&amp;#160;31,
       2009 converted into our common units on a

       We use ASC&amp;#160;718 to account for equity-based compensation
       expense related to awards issued under our long-term incentive
       plan (&amp;#8220;LTIP&amp;#8221;). As of June&amp;#160;30, 2010, the number of
       units available for grant under our LTIP totaled 1,365,128, of
       which up to 783,049&amp;#160;units were eligible to be issued as
       restricted common units, phantom units or unit awards.
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt; font-size: 1pt"&gt;&amp;#160;
   &lt;/div&gt;
   &lt;div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 3%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: #ffffff"&gt;
       &lt;i&gt;Equity Awards.&lt;/i&gt;&amp;#160;&amp;#160;We recognized non-cash
       compensation expense of $3,945,000 and $3,553,000 related to the
       amortization of equity-based compensation under our LTIP during
       the six months ended June&amp;#160;30, 2010 and 2009, respectively.
       See Item&amp;#160;8 in our Annual Report on
       &lt;font style="white-space: nowrap"&gt;Form&amp;#160;10-K&lt;/font&gt;
       for the year ended December&amp;#160;31, 2009 for details on our
       equity-based compensation.
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt; font-size: 1pt"&gt;&amp;#160;
   &lt;/div&gt;
   &lt;div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 3%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: #ffffff"&gt;
       On May&amp;#160;10, 2010 and June&amp;#160;4, 2010, we granted employees
       a total of 180,000 phantom units with a fair value of
       $4,408,000. Each phantom unit grant vests in equal one-third
       annual installments commencing on May&amp;#160;15, 2011 or earlier
       upon change of control, death or disability. The expense will be
       recognized over the vesting period.
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt; font-size: 1pt"&gt;&amp;#160;
   &lt;/div&gt;
   &lt;div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 3%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: #ffffff"&gt;
       On June&amp;#160;4, 2010, we granted 83,000 performance-based
       phantom units to certain management employees. The number of
       performance-based phantom units to vest is dependent on the
       level of achievement of a specified performance goal during the
       period from the grant date through the cliff vesting date of
       May&amp;#160;15, 2013. The fair value of the number of awards
       expected to vest is $4,059,000 and will be recognized over the
       vesting period. Additionally, we will recognize cumulative
       adjustments for changes in the probability of the performance
       goal being met. Under ASC&amp;#160;718, awards containing
       performance conditions, that affect vesting, will recognize
       expense equal to the ultimate outcome of the performance
       condition.
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt; font-size: 1pt"&gt;&amp;#160;
   &lt;/div&gt;
   &lt;div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 3%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: #ffffff"&gt;
       &lt;i&gt;Liability Awards.&lt;/i&gt;&amp;#160;&amp;#160;During the six months ended
       June&amp;#160;30, 2010, we issued 69,817 common units to settle our
       Employee Incentive Compensation Program (&amp;#8220;EICP&amp;#8221;) and
       2009 Management Incentive Compensation Plan (&amp;#8220;MICP&amp;#8221;)
       obligations.
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt; font-size: 1pt"&gt;&amp;#160;
   &lt;/div&gt;
   &lt;div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 3%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: #ffffff"&gt;
       Since ASC&amp;#160;480, &amp;#8220;&lt;i&gt;Accounting for Certain Financial
       Instruments With Characteristics of Both Liabilities and
       Equity&lt;/i&gt;,&amp;#8221; requires unconditional obligations in the form
       of units that the issuer must or may settle by issuing a
   variable number of units to be classified as a liability, we
       classify equity awards issued to settle EICP and MICP
       obligations as liability awards. As of June&amp;#160;30, 2010, we
       accrued $581,000 and $766,000 for the second quarter 2010 EICP
       bonuses and an estimate of the 2010 MICP incentive bonuses,
       respectively. As of June&amp;#160;30, 2010, the estimated
       unrecognized compensation costs related to these liability
       awards totaled $1,104,000 and $1,021,000 for the EICP and MICP,
       respectively, which are expected to be recognized as expense on
       a straight-line basis through December 2010 for EICP awards and
       through February 2011 for MICP awards.
   &lt;/div&gt;
