As a result of the proposed resolution, the Company expects to recognize additional expense of $37 million in its fourth quarter 2011 results. The $37 million additional expense represents the difference between the $64 million proposed credit and the $27 million liability recognized by the Company in prior periods.

To the extent any statements made in this report contain information that is not historical, these statements are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (collectively, "forward-looking statements").

These forward-looking statements relate to, among other things, the stipulated resolution of issues asserted by the Staff in connection with the Nicor Gas Performance-Based Rate plan and the expected impact on the Company's 2011 or 2012 consolidated statements of income. Forward-looking statements can generally be identified by the use of words such as "believe", "anticipate", "expect", "estimate", "intend", "continue", "plan", "project", "will", "may", "should", "could", "would", "target", "potential" and other similar expressions. Although certain of these statements set out herein are indicated above, all of the statements in this release that contain forward-looking statements are qualified by these cautionary statements. Although Nicor Gas Company believes that the expectations reflected in such forward-looking statements are reasonable, such statements involve risks and uncertainties, and undue reliance should not be placed on such statements. Certain material factors or assumptions are applied in making forward-looking statements, including, but not limited to, factors and assumptions regarding the items outlined above. Actual results may differ materially from those expressed or implied in such statements. Important factors that could cause actual results to differ materially from these expectations include, among other things, the following: the possibility that the ICC may not approve the stipulation and other risk factors relating to this matter, as detailed from time to time in Nicor Gas Company's reports filed with the Securities and Exchange Commission ("SEC").

Additional information about these factors and about the material factors or assumptions underlying such forward-looking statements may be found in the body of this report, as well as under Item 1.A. in Nicor Gas Company's Annual Report on Form 10-K for the fiscal year December 31, 2010. AGL Resources cautions that the foregoing list of important factors that may affect future results is not exhaustive. When relying on forward-looking statements to make decisions with respect to AGL Resources, investors and others should carefully consider the foregoing factors and other uncertainties and potential events. All subsequent written and oral forward-looking statements concerning the proposed resolution or other matters attributable to AGL Resources or any other person acting on its behalf are expressly qualified in their entirety by the cautionary statements referenced above. The forward-looking statements contained herein speak only as of the date of this presentation. AGL Resources does not undertake any obligation to update or revise any forward-looking statement, except as may be required by law.
