   Gas&amp;#8221;), the Company&amp;#8217;s wholly-owned subsidiary, had a credit agreement with a syndicate of
   banks, and this credit facility has a borrowing base of $1.1&amp;#160;billion with $1,069.6&amp;#160;million
   of available borrowing capacity, which is net of $30.0&amp;#160;million in borrowings and $0.4

       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;The credit agreement provides for interest only payments until April&amp;#160;2012, when the
   agreement expires and all outstanding borrowings are due.&lt;/td&gt;
   &lt;/tr&gt;

       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;The borrowing base under the credit agreement is determined at the discretion of the
   lenders, based on the collateral value of the proved reserves that have been mortgaged to
   the lenders, and is 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 reduce the amount of the borrowing base. Whiting Oil and Gas may, throughout the
   term of the credit agreement, borrow, repay and reborrow 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 may be used to issue letters of credit for the account of Whiting
   Oil and Gas or other designated subsidiaries of the Company. As of June&amp;#160;30, 2010, $49.6
   million was available for additional letters of credit under the agreement.&lt;/td&gt;

       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;

   the margin in the table below, where the base rate is defined as the greatest of the prime
   rate, the federal funds rate plus 0.50% or an adjusted LIBOR rate plus 1.00%, or (ii)&amp;#160;an
   adjusted LIBOR rate for a Eurodollar loan plus the margin in the table below. The Company
   also incurs commitment fees of 0.50% on the unused portion of the lesser of the aggregate
   commitments of the lenders or the borrowing base, which are included as a component of
   interest expense. At June&amp;#160;30, 2010, the weighted average interest rate on the outstanding
   principal balance under the credit agreement was 2.4%.&lt;/td&gt;

       &lt;td&gt;The credit agreement contains restrictive covenants that may limit 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 requires the Company, as of the last day of any quarter, (i)&amp;#160;to not exceed a total
   debt to the last four quarters' 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' EBITDAX ratio (as defined in the credit agreement) of 2.5 to
   1.0. Except for limited exceptions, which include the payment of dividends on the Company&amp;#8217;s
   6.25% convertible perpetual preferred stock, the credit agreement restricts 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
