       &lt;td&gt;&lt;b&gt;&lt;i&gt;Common Stock&lt;/i&gt;&lt;/b&gt;&amp;#8212;In May&amp;#160;2010, Whiting&amp;#8217;s stockholders approved an amendment to the Company&amp;#8217;s
   Amended and Restated Certificate of Incorporation to increase the number of authorized
   shares of common stock from 75,000,000 shares to 175,000,000 shares.&lt;/td&gt;

       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;&lt;i&gt;Common Stock Offering&lt;/i&gt;. In February&amp;#160;2009, the Company completed a public offering of its
   common stock, selling 8,450,000 shares of common stock at a price of $29.00 per share and
   providing net proceeds of $234.8&amp;#160;million after underwriters&amp;#8217; fees and offering expenses.
   The Company used the net proceeds to repay a portion of the debt outstanding under its
   credit agreement.&lt;/td&gt;

       &lt;td&gt;&lt;b&gt;&lt;i&gt;6.25% Convertible Perpetual Preferred Stock&lt;/i&gt;&lt;/b&gt;&amp;#8212;In June&amp;#160;2009, the Company completed a public
   offering of 6.25% convertible perpetual preferred stock (&amp;#8220;preferred stock&amp;#8221;), selling
   3,450,000 shares at a price of $100.00 per share and providing net proceeds of $334.1
   million after underwriters&amp;#8217; fees and offering expenses. The Company used the net proceeds
   to repay a portion of the debt outstanding under its credit agreement.&lt;/td&gt;
   &lt;/tr&gt;

       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;Each holder of the preferred stock is entitled to an annual dividend of $6.25 per share to
   be paid quarterly in cash, common stock or a combination thereof on March&amp;#160;15, June&amp;#160;15,
   September&amp;#160;15 and December&amp;#160;15, when and if such dividend has been declared by Whiting&amp;#8217;s board
   of directors. Each share of preferred stock has a liquidation preference of $100.00 per
   share plus accumulated and unpaid dividends and is convertible, at a holder&amp;#8217;s option, into
   shares of Whiting&amp;#8217;s common stock based on an initial conversion price of $43.4163, subject
   to adjustment upon the occurrence of certain events. The preferred stock is not redeemable
   by the Company. At any time on or after June&amp;#160;15, 2013, the Company may cause all
   outstanding shares of this preferred stock to be converted into shares of common stock if
   the closing price of our common stock equals or exceeds 120% of the then-prevailing
   conversion price for at least 20 trading days in a period of 30 consecutive trading
   days. The holders of preferred stock have no voting rights unless dividends payable on the
   preferred stock are in arrears for six or more quarterly periods.&lt;/td&gt;
   &lt;/tr&gt;
   &lt;tr&gt;
       &lt;td style="font-size: 6pt"&gt;&amp;#160;&lt;/td&gt;

       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;&lt;i&gt;Induced Conversion of 6.25% Convertible Perpetual Preferred Stock. &lt;/i&gt;In August&amp;#160;2010, Whiting
   commenced an offer to exchange up to 3,277,500, or 95%, of its preferred stock for the
   following consideration per share of preferred stock: 2.3033 shares of its common stock and
   a cash premium of $14.50. The exchange offer expired in September&amp;#160;2010 and resulted in the
   Company accepting 3,277,500 shares of preferred stock in exchange for the issuance of
   7,549,010 shares of common stock and a cash premium payment of $47.5&amp;#160;million. Following the
   exchange offer, the 3,277,500 shares of preferred stock accepted in the exchange were
   cancelled, and a total of 172,500 shares of preferred stock remained outstanding.&lt;/td&gt;
   &lt;/tr&gt;
   &lt;/table&gt;
   &lt;/div&gt;
