Item 5. Other Events and Regulation FD Disclosure

Incident to the pending sale of common stock by the Company, the following
update is being provided.

1.    In early August, 2003, the Company disposed of its interest in two
      non-regulated businesses. These actions were in furtherance of the
      Company's objective to narrow the scope of its non-regulated businesses.
      Proceeds realized from these dispositions will be used to reduce
      outstanding debt at the Company's non-regulated business. The consummation
      of both transactions was previously included in the Company's 2003
      earnings guidance that was provided on July 9, 2003.


         The first disposition was closed as of August 1, 2003, when Vectren
         Energy Marketing and Services, Inc. (VEMS), a wholly-owned, indirect
         subsidiary of the Company, consummated the sale of its investment in
         Genscape, Inc., a supplier of real-time power plant output and
         transmission information, to GFI Energy Ventures, LLC. The after-tax
         gain realized by the Company was approximately $2.6 million.

         The second disposition was closed on August 4, 2003, and involved
         CIGMA, LLC (CIGMA), a joint venture between Vectren Utility Services,
         Inc., an indirect, wholly-owned subsidiary of the Company, and a
         subsidiary of Citizens Gas & Coke Utility. In that transaction,
         substantially all of CIGMA's assets were sold to McJunkin Corporation.
         CIGMA had been engaged in utility materials management for the
         Company's utility subsidiaries, Citizens Gas & Coke Utility, and
         others. As a result of the transaction, the Company realized a small
         after-tax gain, and received a cash dividend from CIGMA of $4 million.

2.    The following is an update on two regulatory matters in Ohio. Each of the
      discussed matters is currently pending before the Public Utilities
      Commission of Ohio (PUCO).

         The first matter relates to an application made to the PUCO by Vectren
         Energy Delivery of Ohio, Inc. (VEDO), an indirect, wholly-owned
         subsidiary of the Company, together with other regulated Ohio gas
         utilities, for authority to establish a tariff mechanism to recover
         expenses related to uncollectible accounts pursuant to an automatic
         adjustment procedure. The application is pending before the PUCO and,
         if granted, will enable VEDO to better match revenues with costs
         associated with fulfilling its obligation to serve customers who are
         unable to pay their bills. Presently, the amount provided for in VEDO's
         base rates is not adequate to cover the total expenses relating to
         uncollectible accounts. The actual positive impact of the tariff
         mechanism will vary with the as-billed price of natural gas and the
         number of customers who are unable to pay their bills. While the
         Company believes there is a sound basis for the PUCO to grant the
         application to recover actual expenses relating to uncollectible
         accounts, no assurance can be provided with respect to the ultimate
         outcome of this proceeding.

         The second matter concerns the requirement in Ohio that gas utilities,
         including VEDO, undergo a biannual audit of their gas acquisition
         practices in connection with the gas cost recovery (GCR) mechanism. In
         the case of VEDO, on or about August 15, 2003, a third-party consulting
         firm engaged by the Staff of the PUCO, is scheduled to conclude an
         audit report to be filed with the PUCO. The audit report will provide
         the results of that firm's review of VEDO's gas acquisition practices
         for the biannual period commencing November 1, 2000 (the first day of
         operations by VEDO) through October 31, 2002. The audit will provide
         the initial opportunity, in the context of a PUCO GCR proceeding, for a
         review of the portfolio administration arrangement between VEDO and
         ProLiance Energy, LLC (ProLiance), a joint venture between a Company
         subsidiary and a subsidiary of Citizens Gas & Coke Utility. Similar
         arrangements for the Company's other utility subsidiaries, Indiana Gas
         Company, Inc. and Southern Indiana Gas and Electric Company, were
         previously reviewed and approved by the Indiana Utility Regulatory
         Commission. VEDO's prior gas acquisition practices may be challenged in
         the audit report, including VEDO's relationship with ProLiance, and, as
         a result, a gas cost disallowance may be recommended. Should such a
         challenge be made, then, by the first of September 2003, VEDO would
         file its response. If a hearing is necessary, the earliest it could
         occur would be mid-September 2003. After that hearing, the PUCO would
         consider all of the evidence on the matter and make a determination on
         the merits. Throughout this process VEDO could, and likely would,
         endeavor to engage in efforts with the participants in the proceeding
         to resolve disputed issues outside of administrative litigation. The
         Company believes that VEDO's gas acquisition practices that are the
         subject of the audit were reasonable. If a challenge is made with
         respect to VEDO's gas acquisition practices during the audit period and
         that challenge was adopted by the PUCO, the Company believes that it
         would not be reasonably likely to have a material effect on the
         Company's results or financial condition. However, the Company can
         provide no assurance as to the ultimate outcome of this proceeding.

      income statement and cash flow statement data for the six months ended
      June 30, 2003 and 2002 and balance sheet data as of June 30, 2003.

In connection with the "safe harbor" provisions of the Private Securities
Litigation Reform Act of 1995, the Company is hereby filing cautionary
statements identifying important factors that could cause actual results of the
Company and its subsidiaries, including Vectren Utility Holdings, Inc., Indiana
Gas Company, Inc. and Southern Indiana Gas and Electric Company, to differ
materially from those projected in forward-looking statements of the Company and
its subsidiaries made by, or on behalf of, the Company and its subsidiaries.
