Energy-Related Activities Pursuant to SEC Orders in File No. 70-9803

By orders in the above-referenced file dated May 4, 2001 (HCAR No. 27393) and March 21, 2002 (HCAR No. 27506) (collectively, the “Orders”), the Commission authorized Cinergy to, among other things, engage in certain nonutility businesses both inside and in certain countries outside the United States, subject to the terms and conditions specified in those orders. More specifically, through one or more existing or future nonutility subsidiaries, Cinergy was authorized to engage in the business of brokering and marketing energy commodities in the United States, Canada and Mexico and was authorized to engage in the business of providing energy management services and energy-related consulting services (in each case as defined in the Orders) anywhere in the world.

The following summarizes activity conducted on the authority granted by the Orders during the period covered by this Report:

As previously reported herein, Cinergy has an indirect wholly-owned subsidiary, Cinergy Canada, Inc. (“Cinergy Canada”). During the first quarter of 2004, Cinergy Canada acquired the assets of a Canadian natural gas marketing business. With the acquisition of these assets, Cinergy Canada intends to provide natural gas marketing and management services to third-party producers and industrial customers in Canada. Cinergy Canada is currently operating in various Canadian provinces.

Cinergy Solutions — Demand, Inc. (formerly knows as Vestar, Inc.) and its subsidiaries (collectively, “Demand”) are in the business of marketing energy management services and solutions, intended to create cost savings and improve efficiency and productivity, to institutional, commercial and industrial customers in the United States and Canada. As of September 30, 2004, Demand continued to be actively engaged in its North American energy management and energy performance contracting business.

In the first quarter of 2004, four new indirect, wholly-owned subsidiaries of Cinergy, Cinergy Mexico Limited, LLC, Cinergy Mexico General, LLC, Cinergy Mexico Holdings, L.P. and Cinergy Mexico Marketing & Trading, LLC, were formed. Cinergy Mexico Limited, LLC is the sole limited partner and Cinergy Mexico General, LLC is the sole general partner of Cinergy Mexico Holdings, L.P., which was formed to engage in the sale, purchase and marketing of natural gas in Mexico and related risk management activities, and to hold an ownership interest in Cinergy Mexico Marketing & Trading, LLC. Cinergy Mexico Marketing & Trading, LLC was formed for the purpose of engaging in the marketing of natural gas and/or natural gas-related services in Mexico. As of September 30, 2004, these companies were in the start-up phase of operations, and Cinergy was not actively engaged in the business of brokering and marketing any energy commodities in Mexico, through these companies or otherwise.
