       &lt;td&gt;&lt;b&gt;&lt;i&gt;Credit Agreement&lt;/i&gt;&lt;/b&gt;&amp;#8212;As of September&amp;#160;30, 2010, Whiting Oil and Gas Corporation (&amp;#8220;Whiting
   Oil and Gas&amp;#8221;), the Company&amp;#8217;s wholly-owned subsidiary, had a credit agreement with a
   syndicate of banks, and this credit facility had a borrowing base of $1.1&amp;#160;billion with
   $999.6&amp;#160;million of available borrowing capacity, which was net of $100.0&amp;#160;million in
   borrowings and $0.4&amp;#160;million in letters of credit outstanding. The credit agreement provided
   for interest only payments until April&amp;#160;2012, when the agreement expired and all outstanding
   borrowings were due. In October&amp;#160;2010, Whiting Oil and Gas entered into a Fifth Amended and
   Restated Credit Agreement with its bank syndicate, which replaced the existing credit
   agreement. This amended credit agreement extended the principal repayment date from April
   2012 to October&amp;#160;2015. Further information on the terms of the new credit agreement is
   discussed in the note on Subsequent Events. The following is a description of the credit
   agreement in place as of September&amp;#160;30, 2010.&lt;/td&gt;
   &lt;/tr&gt;
   &lt;/table&gt;
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt"&gt;
   &lt;table width="100%" border="0" cellpadding="0" cellspacing="0" style="font-size: 10pt; text-align: left"&gt;

       &lt;td width="3%" nowrap="nowrap" align="left"&gt;&amp;#160;&lt;/td&gt;
       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;The borrowing base under the credit agreement was determined at the discretion of the
   lenders, based on the collateral value of the proved reserves that had been mortgaged to the
   lenders, and was subject to regular redeterminations on May 1 and November 1 of each year,
   as well as special redeterminations described in the credit agreement, in each case which
   may have reduced the amount of the borrowing base. Whiting Oil and Gas could have,
   throughout the term of the credit agreement, borrowed, repaid and reborrowed up to the
   borrowing base in effect at any given time. A portion of the revolving credit agreement in
   an aggregate amount not to exceed $50.0&amp;#160;million could have been used to issue letters of
   credit for the account of Whiting Oil and Gas or other designated subsidiaries of the
   Company. As of September&amp;#160;30, 2010, $49.6&amp;#160;million was available for additional letters of
   credit under the agreement.&lt;/td&gt;
   &lt;/tr&gt;
   &lt;/table&gt;
   &lt;/div&gt;

   also incurred commitment fees of 0.50% on the unused portion of the lesser of the aggregate
   commitments of the lenders or the borrowing base, which were included as a component of
   interest expense. At September&amp;#160;30, 2010, the weighted average interest rate on the

       &lt;td&gt;The credit agreement contained restrictive covenants that may have limited the
   Company&amp;#8217;s ability to, among other things, incur additional indebtedness, sell assets, make
   loans to others, make investments, enter into mergers, enter into hedging contracts, incur
   liens and engage in certain other transactions without the prior consent of its lenders.
   The credit agreement required the Company, as of the last day of any quarter, (i)&amp;#160;to not
   exceed a total debt to the last four quarters&amp;#8217; EBITDAX ratio (as defined in the credit
   agreement) of 4.5 to 1.0 for quarters ending prior to and on September&amp;#160;30, 2010, 4.25 to 1.0
   for quarters ending December&amp;#160;31, 2010 to June&amp;#160;30, 2011 and 4.0 to 1.0 for quarters ending
   September&amp;#160;30, 2011 and thereafter, (ii)&amp;#160;to have a consolidated current assets to
   consolidated current liabilities ratio (as defined in the credit agreement and which
   includes an add back of the available borrowing capacity under the credit agreement) of not
   less than 1.0 to 1.0, and (iii)&amp;#160;to not exceed a senior secured debt to the last four
   quarters&amp;#8217; EBITDAX ratio (as defined in the credit agreement) of 2.5 to 1.0. Except for
   limited exceptions, which included the payment of dividends on the Company&amp;#8217;s 6.25%
   convertible perpetual preferred stock, the credit agreement restricted its ability to make
   any dividend payments or distributions on its common stock or principal payments on its
   senior notes. The Company was in compliance with its covenants under the credit agreement

       &lt;td&gt;The obligations of Whiting Oil and Gas under the credit agreement were secured by a first
   lien on substantially all of Whiting Oil and Gas&amp;#8217; properties included in the borrowing base

   Whiting Oil and Gas under the credit agreement and pledged the stock of Whiting Oil and Gas

   Senior Subordinated Notes due February&amp;#160;2014. The estimated fair value of these notes was
   $263.8&amp;#160;million as of September&amp;#160;30, 2010, based on quoted market prices for these same debt

       &lt;td&gt;&lt;i&gt;Redemption of 7.25% Senior Subordinated Notes Due 2012 and 2013&lt;/i&gt;&amp;#8212;In September&amp;#160;2010, the
   Company paid $383.5&amp;#160;million to redeem all of its $150.0&amp;#160;million aggregate principal amount
   of 7.25% Senior Subordinated Notes due 2012 and all of its $220.0&amp;#160;million aggregate
   principal amount of 7.25% Senior Subordinated Notes due 2013, which consisted of a
   redemption price of 100.00% for the 2012 notes and 101.8125% for the 2013 notes and included
   the payment of accrued and unpaid interest on such notes. The Company financed the
   redemption of the 2012 and 2013 notes with borrowings under its credit agreement. As a
   result of the redemption, Whiting recognized a $6.2&amp;#160;million loss on early extinguishment of
   debt, which consisted of a cash charge of $4.0&amp;#160;million related to the redemption premium on
   the 2013 notes and a non-cash charge of $2.2&amp;#160;million related to the acceleration of debt
   discounts and unamortized debt issuance costs.&lt;/td&gt;

       &lt;td&gt;&lt;i&gt;Issuance of 6.5% Senior Subordinated Notes Due 2018&lt;/i&gt;&amp;#8212;In September&amp;#160;2010, the Company issued
   at par $350.0&amp;#160;million of 6.5% Senior Subordinated Notes due October&amp;#160;2018. The Company used
   the net proceeds from this issuance to repay a portion of the debt, which was borrowed to
   redeem its 2012 and 2013 notes, outstanding under its credit agreement. The estimated fair
   value of these notes was $357.4&amp;#160;million as of September&amp;#160;30, 2010, based on quoted market
   prices for these same debt securities.&lt;/td&gt;
