Item 5.  Other Events.

Vectren  Corporation  provides  update on Gas Cost  Adjustment  Proceedings  and
Commission Order

On October 11, 2000,  Indiana Gas Company,  Inc.  (Indiana  Gas), a wholly-owned
subsidiary of Vectren Corporation,  filed for approval of its quarterly gas cost
adjustment (GCA). In early December,  the Indiana Utility Regulatory  Commission
issued an interim  order  approving  the request by Indiana Gas for a GCA factor
for December 2000. On January 4, 2001,  the Commission  approved the January and
February 2001 GCA as filed.  The order also addressed the claim by the Office of
the Utility  Consumer  Counselor  (OUCC) that a portion of the  requested GCA be
disallowed  because Indiana Gas should have entered into additional  commitments
for this  winter's  gas supply in late 1999 and early  2000.  In  procuring  gas
supply for this winter,  Indiana Gas followed the gas procurement practices that
it had  employed  over the last several  years.  In response to the claim by the
OUCC,  the  Commission  found  that there  should be a  one-time,  $3.8  million
disallowance  related to gas  procurement  for the winter  season.  As a result,
Indiana Gas expects to recognize a pre-tax  charge of $3.8 million during fiscal
year 2000.
