Management evaluates its estimates and related assumptions regularly, including those related to the impairment of oil and natural gas properties, oil and natural gas reserves, derivatives, income taxes, collectibility of accounts receivable, impairment of other property and equipment, environmental remediation costs, asset retirement obligations, litigation and regulatory proceedings and fair values. Changes in facts and circumstances or additional information may result in revised estimates, and actual results may differ significantly from these estimates.</font></div><div style="line-height:120%;padding-top:8px;text-align:justify;text-indent:29px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;color:#000000;font-style:italic;"></font></div></div>
