       &lt;td&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;On June&amp;#160;30, 2009, Steven L. Beal, the Company&amp;#8217;s then President and Chief Operating Officer,
   retired from such positions. On June&amp;#160;9, 2009, the Company entered into a consulting agreement
   (the &amp;#8220;Consulting Agreement&amp;#8221;) with Mr.&amp;#160;Beal, under which Mr.&amp;#160;Beal began serving as a consultant
   to the Company on July&amp;#160;1, 2009. Either the Company or Mr.&amp;#160;Beal may terminate the consulting
   relationship at any time by giving ninety days written notice to the other party; however, the
   Company may terminate the relationship immediately for cause. During the term of the
   consulting relationship, Mr.&amp;#160;Beal will receive a consulting fee of $20,000 per month and a
   monthly reimbursement for his medical and dental coverage costs. If Mr.&amp;#160;Beal dies during the
   term of the Consulting Agreement, his estate will receive a $60,000 lump sum payment. As part
   of the consulting agreement, certain of Mr.&amp;#160;Beal&amp;#8217;s stock-based awards were modified to permit
   vesting and exercise under the original terms of the stock-based awards as if Mr.&amp;#160;Beal were
   still an employee of the Company while he is performing consulting services for the Company.
   The tables above summarize the Company&amp;#8217;s activities pursuant to the consulting agreement with
   this director.&lt;/td&gt;
   &lt;/tr&gt;
   &lt;/table&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;b&gt;&lt;i&gt;Saltwater disposal services agreement. &lt;/i&gt;&lt;/b&gt;Among the assets the Company acquired from Chase Oil is
   an undivided interest in a saltwater gathering and disposal system, which is owned and maintained
   under a written agreement among the Company and Chase Oil and certain of its affiliates, and under
   which the Company as operator gathers and disposes of produced water. The system is owned jointly
   by the Company and Chase Oil and its affiliates in undivided ownership percentages, which are
   annually redetermined as of January 1 on the basis of each party&amp;#8217;s percentage contribution of the
   total volume of produced water disposed of through the system during the prior calendar year. As of
   January&amp;#160;1, 2010, the Company owned 97.5&amp;#160;percent of the system and Chase Oil and its affiliates
   owned 2.5&amp;#160;percent.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;b&gt;&lt;i&gt;Purchase of residence. &lt;/i&gt;&lt;/b&gt;During the second quarter of 2010, the Company purchased the Houston,
   Texas residence of Darin G. Holderness, the Company&amp;#8217;s Vice President, Chief Financial Officer and
   Treasurer. To effectuate the purchase, the Company
   engaged a third-party relocation company, who executed the purchase
   for $920,000 and will subsequently sell Mr.
   Holderness&amp;#8217; residence. The third-party relocation company appraised the fair value of Mr.
   Holderness&amp;#8217; residence at $920,000.
   &lt;/div&gt;
