Issuer Delisting; Notice of Application of NiSource Inc., To Withdraw Its Common Stock, $.01 Par Value, and the Preferred Stock Purchase Rights, From Listing and Registration on the Chicago Stock Exchange, Inc. File No. 1-09779

On December 13, 2005, NiSource Inc., a Delaware corporation (“Issuer”), filed an application with the Securities and Exchange Commission (“Commission”), pursuant to section 12(d) of the Securities Exchange Act of 1934 (“Act”) and Rule 12d2-2(d) thereunder, to withdraw its common stock, $.01 par value, and the preferred stock purchase rights (collectively “Securities”), from listing and registration on the Chicago Stock Exchange, Inc. (“CHX”).

The Board of Directors (“Board”) of the Issuer approved a resolution on October 25, 2005 to withdraw the Securities from CHX and the Pacific Exchange, Inc., (“PCX”). The Issuer stated that the following reasons factored into the Board's decision to withdraw the Securities from CHX and PCX: (i) the costs and administrative burdens of complying with both CHX and PCX rules and regulations outweigh the utility to the Issuer and its shareholders of having the Securities listed on such exchange; and (ii) the Securities are listed on the New York Stock Exchange, Inc. (“NYSE”) and will continue to list on NYSE.

The Issuer stated in its application that it has complied with applicable rules of CHX by complying with all applicable laws in the State of Delaware, the state in which the Issuer is incorporated, and by providing CHX with the required documents governing the withdrawal of securities from listing and registration on CHX. The Issuer's application relates solely to the withdrawal of the Securities from listing on CHX and shall not affect their continued listing on NYSE or PCX, or their obligation to be registered under section 12(b) of the Act.

Any interested person may, on or before February 1, 2006, comment on the facts bearing upon whether the application has been made in accordance with the rules of CHX, and what terms, if any, should be imposed by the Commission for the protection of investors. All comment letters may be submitted by either of the following methods:
