ITEM 5. OTHER EVENTS

This Current Report on Form 8-K is to reflect the presentation of Columbia
Energy Resources, Inc. and the steel-industry-related, inside-the-fence project
entities of Primary Energy, Inc. as discontinued operations. The changes affect
the financial statements and related notes including Schedules I and II,
management's discussion and analysis, and the selected financial data as
reported in our 8-K filed July 15, 2003 regarding our Annual Report on Form
10-K/A for the fiscal year ended December 31, 2002. Exhibit 99.1 contains
information identical to the corresponding sections of the registrants' 8-K
filed July 15, 2003 regarding the Annual Report on Form 10-K/A for the fiscal
year ended December 31, 2002, except that all such information has been updated
to the extent required to reflect Columbia Energy Resources, Inc. and the
steel-industry-related, inside-the-fence project entities of Primary Energy,
Inc. as discontinued operations. As a result of the Columbia Energy Resources,
Inc. being classified as discontinued operations, NiSource no longer reports the
Exploration and Production segment.
