Item 5.  Other Events

The Securities and Exchange Commission (SEC) recently issued Regulation G,
concerning the use of non-GAAP financial measures in registrant's financial
statements. These rules became effective March 28, 2003. Prior to the effective
date, on March 20, 2003, the SEC issued interpretations of that Regulation
concerning, among other things, the incorporation by reference of financial
statements in registration statements. In anticipation of the incorporation by
reference in future registration statements of Vectren Corp.'s 2002 Annual
Report on Form 10K filed on March 18, 2003 and in order to fully comply with
Regulation G, the table labeled Cash Flow From Operating Activities under the
Financial Condition, Sources & Uses of Liquidity, section of Item 7
"Management's Discussion and Analysis of Results of Operations and Financial
Condition" should be deleted. That section of Item 7 now reads as follows:

The Company's primary historical source of liquidity to fund working capital
requirements has been cash generated from operations. Cash flow from operating
activities increased during the year ended December 31, 2002 compared to 2001 by
$104.2 million and increased $141.5 million in 2001 compared to 2000. The
primary reasons for the increases are favorable changes in working capital
accounts due to a return to lower gas prices and increased earnings before
non-cash charges.
