   &lt;div align="left" style="font-size: 10pt; margin-top: 12pt"&gt;&lt;b&gt;Note Q. &lt;/b&gt;&lt;b&gt;&lt;i&gt;Subsequent events&lt;/i&gt;&lt;/b&gt;
   &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;Marbob Acquisition. &lt;/i&gt;&lt;/b&gt;
   On July 19, 2010, the Company entered into an asset purchase agreement to acquire
   substantially all of the oil and natural gas leases, interests, properties and related
   assets owned by Marbob Energy Corporation and certain affiliated entities (collectively, &amp;#8220;Marbob&amp;#8221;)
   for aggregate consideration of approximately $1.65 billion, subject to purchase price adjustments,
   which include downward purchase price adjustments based on the exercise of third parties of contractual
   preferential rights to purchase certain interests in properties to be acquired from Marbob
   (the &amp;#8220;Marbob Acquisition&amp;#8221;).  Upon closing, the consideration is expected to consist of (i) cash
   consideration in the aggregate amount of $1.45 billion, (ii) the issuance by the Company to Marbob
   of an 8 percent unsecured promissory note due 2018 in the aggregate principal amount of $150 million
   and (iii) the issuance to Marbob of approximately 1.1 million shares of the Company&amp;#8217;s common stock
   (representing a negotiated value of $50 million). The Marbob Acquisition is expected to close on or
   before November 30, 2010.
   &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;The Company intends to finance the $1.45 billion cash portion of the Marbob Acquisition with a combination of
    equity and debt.  On July 19, 2010, the Company entered into a common stock purchase agreement with third-party
   investors to sell approximately 6.6 million shares of the Company&amp;#8217;s common stock in a private placement for
   aggregate cash consideration of approximately $300 million. The Company anticipates that this private placement
   will close simultaneously with the Marbob Acquisition. In addition, the Company has received an $800 million
   underwritten commitment from two of its lenders under its Credit Facility to expand the size of its existing Credit
   Facility from $1.2 billion to $2.0 billion as part of the financing for the Marbob Acquisition, which the Company
   expects will provide the credit capacity to fund the remaining cash portion of the purchase price.  The expanded
   credit facility is expected to close simultaneously with the Marbob Acquisition.
   &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;Marbob preferential rights. &lt;/i&gt;&lt;/b&gt;
   Certain of the Marbob interests in properties contain contractual preferential rights
   to purchase by third parties if Marbob were to sell   them. Marbob has informed the Company of the receipt by
   Marbob of a notice from BP America Production Company (&amp;#8220;BP&amp;#8221;) electing to exercise its contractual preferential
   purchase right under certain operating agreements to purchase interests in certain of Marbob&amp;#8217;s properties as a result
   of the Marbob Acquisition. The approximate value of the interests in properties associated with this election is $400
   million, which, if closed between Marbob and BP, would reduce the purchase price of the Marbob Acquisition.
   &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;In addition, Marbob has contractual preferential rights under certain operating agreements to purchase certain
   interests in properties if third parties were  to sell those interests in properties. On July 20, 2010, BP
   announced it was selling all its assets in the Permian Basin to a subsidiary of Apache Corporation (&amp;#8220;Apache&amp;#8221;).
   Marbob and BP own common interests in certain common properties subject to a contractual preferential right to
   purchase. BP and Apache have contested Marbob&amp;#8217;s ability to exercise its contractual preferential rights in this
   situation. As a result, Marbob and the Company have filed suit against BP and Apache seeking declaratory judgment
   and injunctive relief to protect Marbob&amp;#8217;s contractual right to have the option to purchase these interests in properties.
   The Company is unable to predict at this time if the court will grant Marbob and the Company the relief sought in
   connection with the suit.

   price swaps to protect the Company&amp;#8217;s cash flows in anticipation of the Marbob Acquisition:
