NAPERVILLE, Ill., Dec. 11, 2003 — Nicor Inc. released the following statement in response to Thursday’s announcements by the Office of the United States Attorney for the Northern District of Illinois and the Securities and Exchange Commission regarding charges against former employees of Nicor Energy, LLC, a 50-percent owned joint venture with Dynegy Marketing and Trade that is no longer in operation.
— During the time period covered by the charged conduct, Nicor Energy, a retail energy marketing business, had its own management and was operated separately from Nicor Inc. and Nicor Gas.

Nicor Inc. has cooperated fully throughout the investigation and is pleased that this matter has now come to a resolution.
— Nicor Inc. wrote down to zero its investment in this joint venture in the third quarter 2002. These indictments are not expected to have a material impact on the financial results of Nicor Inc.
