(1)  Merger and integration related costs and restructuring costs incurred for
     the twelve months ended June 30, 2001 and for the year ended December 31,
     2000 totaled $7.3 million and $16.8 million, respectively. These costs
     relate primarily to transaction costs, severance, elimination of duplicate
     facilities, and other merger, integration and restructuring activities.

     As a result of merger integration activities, management has identified
     certain information systems that are expected to be retired in 2001.
     Accordingly, the useful lives of these assets have been shortened to
     reflect this decision. These information system assets are owned by a
     wholly owned subsidiary of Vectren and the fees allocated by the subsidiary
     for the use of these systems by Indiana Gas are reflected in operation and
     maintenance expenses in the accompanying condensed financial statements. As
     a result of the shortened useful lives, additional fees were incurred by
     Indiana Gas. For the twelve months ended June 30, 2001 and for the year
     ended December 31, 2000, these additional fees increased operation and
     maintenance $13.6 million and $11.4 million, respectively.

     In total, merger and integration related costs incurred for the twelve
     months ended June 30, 2001 and for the year ended December 31, 2000 were
     $20.8 million ($12.9 million after tax) and $28.2 million ($19.5 million
     after tax), respectively. Before merger and integration and restructuring
     charges, Indiana Gas' ratio of earnings to fixed charges for the twelve
     months ended June 30, 2001 was 1.8 and for the year ended December 31, 2000
     was 2.7.

(2)  The Indiana Gas Board of Directors authorized management to undertake the
     actions necessary and appropriate to restructure Indiana Gas 'operations
     and recognize a resulting restructuring charge of $39.5 million ($24.5
     million after tax) which included estimated costs related to involuntary
     workforce reductions. Indiana Gas' ratio of earnings to fixed charges for
     1997 before restructuring costs was 4.4.
