Item 1.  Changes in Control of Registrant

Vectren Corporation (Vectren) is an Indiana corporation
organized on June 10, 1999 solely for the purpose of
effecting the merger of Indiana Energy, Inc. (Indiana
Energy) and SIGCORP, Inc. (SIGCORP) with and into Vectren
and carrying on the combined business of Indiana Energy and
SIGCORP.  Following the merger of Indiana Energy and SIGCORP
into Vectren, all the outstanding common shares of the
direct subsidiaries of Indiana Energy and SIGCORP will
be owned by Vectren and former holders of Indiana Energy and
SIGCORP common shares will own all of the outstanding
Vectren common shares.

On March 31, 2000, Indiana Energy and SIGCORP were merged
with and into Vectren.  Vectren, as the successor to
SIGCORP, is now the parent of Southern Indiana Gas and
Electric Company (SIGECO).  Vectren now owns all of the
outstanding common shares of SIGECO. SIGECO's outstanding
preferred stock in the amount of $19,282,000 at December 31,
1999 and outstanding long-term debt in the amount of
$238,282,000 at December 31, 1999 are unaffected by the
merger.

SIGECO is an operating public utility.  SIGECO provides
generation, transmission, distribution and sale of electric
power and the distribution and sale of natural gas in
southwestern Indiana.  In 1999 SIGECO supplied electric
power to approximately 125,000 customers in Evansville,
Indiana and 74 other cities, towns, communities and adjacent
rural areas.  Wholesale electric power was supplied to five
communities.  Gas was supplied to approximately 108,000
customers in Evansville, Indiana and 64 nearby communities
and environs.
