There are allegations that the company acted improperly in connection with the PBR plan, and the ICC and others are reviewing these allegations.&amp;#160;&amp;#160;On June 27, 2002, the Citizens Utility Board (&amp;#8220;CUB&amp;#8221;) filed a motion to reopen the record in the ICC&amp;#8217;s proceedings to review the PBR plan (the &amp;#8220;ICC Proceedings&amp;#8221;).&amp;#160;&amp;#160;As a result of the motion to reopen, Nicor Gas, the staff of the ICC and CUB entered into a stipulation providing for additional discovery.&amp;#160;&amp;#160;The Illinois Attorney General&amp;#8217;s Office (&amp;#8220;IAGO&amp;#8221;) has also intervened in this matter.&amp;#160;&amp;#160;In addition, the IAGO issued Civil Investigation Demands (&amp;#8220;CIDs&amp;#8221;) to CUB and the ICC staff.&amp;#160;&amp;#160;The CIDs ordered that CUB and the ICC staff produce all documents relating to any claims that Nicor Gas may have presented, or caused to be presented, false information related to its PBR plan.&amp;#160;&amp;#160;The company has committed to cooperate fully in the reviews of the PBR plan.&lt;/font&gt;&lt;/div&gt;&lt;div style="DISPLAY: block;

By the end of 2003, the company completed steps to correct the weaknesses and deficiencies identified in the detailed study of the adequacy of internal controls.&lt;/font&gt;&lt;/div&gt;&lt;div style="DISPLAY: block;

responses to certain CUB data requests were false.&amp;#160;&amp;#160;Also on February 5, 2003, CUB stated in a press release that, in addition to $27 million in sanctions, it would seek additional refunds to consumers.&amp;#160;&amp;#160;On March 5, 2003, the ICC staff filed a response brief in support of CUB&amp;#8217;s motion for sanctions.&amp;#160;&amp;#160;On May 1, 2003, the ALJs assigned to the proceeding issued a ruling denying CUB&amp;#8217;s motion for sanctions.&amp;#160;&amp;#160;CUB has filed an appeal of the motion for sanctions with the ICC, and the ICC has indicated that it will not rule on the appeal until the final disposition of the ICC Proceedings.&amp;#160;&amp;#160;It is not possible to determine how the ICC will resolve the claims of CUB or other parties to the ICC Proceedings.&lt;/font&gt;&lt;/div&gt;&lt;div style="DISPLAY: block;

acquisition subsidiaries and, in one instance, Nicor&amp;#8217;s Executive Vice President and Chief Financial Officer have been named as defendants in five putative class action lawsuits brought by purported Nicor shareholders challenging Nicor&amp;#8217;s proposed merger with AGL Resources. The first shareholder action was filed on December 7, 2010 in the Eighteenth Circuit Court of DuPage County, Illinois, County Department, Chancery Division (&lt;font style="DISPLAY: inline; FONT-STYLE: italic"&gt;Joseph Pirolli v.

The shareholder actions seek, among other things, declaratory and injunctive relief, including orders enjoining the defendants from consummating the proposed merger and, in certain instances, damages.&lt;/font&gt;&lt;/div&gt;&lt;div style="DISPLAY: block;
