                            Indiana Gas Company, Inc.

                         Pro Forma Financial Information

The accompanying financial statements present the unaudited pro forma balance
sheet as of September 30, 2000 and the unaudited pro forma statement of income
for the nine months ended September 30, 2000 and for the year ended December 31,
1999.

On October 31, 2000, Vectren Corporation, the parent of Indiana Gas Company,
Inc. (Indiana Gas), completed its acquisition of the natural gas distribution
assets of The Dayton Power and Light Company (Acquisition) for approximately
$465 million pursuant to an Asset Purchase Agreement dated December 14, 1999.
Vectren acquired the gas utility assets as a tenancy in common through two
separate wholly-owned subsidiaries. Operations will be conducted under the name
Vectren Energy Delivery of Ohio, Inc. (VEDO). Under the acquisition structure,
Indiana Gas holds a 47 percent undivided ownership interest and VEDO has a 53
percent undivided ownership interest.

The unaudited pro forma balance sheet as of September 30, 2000 is presented as
if the Acquisition had occurred on September 30, 2000. The pro forma statement
of income for the nine month period ended September 30, 2000 and for the year
ended December 31, 1999 are presented as if the Acquisition had occurred at
January 1, 1999. Indiana Gas' ownership is reflected as being accounted for on
the equity method.

Preparation of the pro forma financial information was based on assumptions
deemed appropriate by management. The pro forma information is unaudited and is
not necessarily indicative of the results which actually would have occurred if
the transaction had been consummated at the beginning of the period presented,
nor does it purport to represent the future financial position and results of
operation for future periods. The pro forma information should be read in
conjunction with the audited historical financial statements of Indiana Gas
filed on Form 10-K/A for the year ended December 31, 1999 and the unaudited
financial statements of Indiana Gas filed on Form 10-Q for the fiscal quarter
ended September 30, 2000.

               INDIANA GAS COMPANY, INC. AND SUBSIDIARY COMPANIES
           NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

1.   Basis of Presentation

Vectren Corporation (Vectren) is a public utility holding company whose
wholly-owned subsidiary, Vectren Utility Holdings, Inc. (VUHI), is the holding
company of Vectren's two operating public utilities, Indiana Gas Company, Inc.
(Indiana Gas) and Southern Indiana Gas and Electric. On October 31, 2000,
Vectren completed its acquisition of the natural gas distribution assets of The
Dayton Power and Light Company (Acquisition) for approximately $465 million
pursuant to an Asset Purchase Agreement dated December 14, 1999. Vectren
acquired the gas utility assets as a tenancy in common through two separate
wholly-owned subsidiaries. Operations will be conducted under the name Vectren
Energy Delivery of Ohio (VEDO). Under the acquisition structure, Indiana Gas
holds a 47 percent undivided ownership interest and VEDO has a 53 percent
undivided ownership interest.

The accompanying combined pro forma financial statements give effect to Indiana
Gas' ownership interest in the Acquisition. The unaudited pro forma balance
sheet as of September 30, 2000 is presented as if the Acquisition had occurred
on September 30, 2000. The pro forma statement of income for the nine month
period ended September 30, 2000 and for the year ended December 31, 1999 are
presented as if the Acquisition had occurred at January 1, 1999. Indiana Gas'
ownership is reflected as being accounted for on the equity method.

2.   Proforma Adjustments to Balance Sheet

(a)  Pro forma adjustment to reflect Indiana Gas' 47 percent ownership  interest
     in the acquired net assets:

     Tangible assets acquired                          $278,080
     Liabilities assumed                                 (7,881)
                                                       --------
                                                        270,199
     Goodwill                                           199,600
                                                       --------

     Indiana Gas' ownership                                  47%
                                                       --------
     Equity Investment in Unconsolidated
      Corporation                                      $220,805
                                                       ========


The total cash paid by Indiana Gas was $218,081,000 plus liabilities assumed of
$2,724,000. The purchase was financed primarily with short-term debt. The
transaction costs totaled $5,818,000 consisting primarily of investment banker
fees (approximately $3.6 million) and accounting and legal fees (approximately
$2.2 million), 47% of which was paid by Indiana Gas.

(b)      Pro forma  adjustment  to reflect the cash  payment  for Indiana  Gas'
         portion of the transaction costs.

(c)      Pro forma adjustment to reflect the debt required to fund Indiana Gas'
         ownership interest in the net assets. Indiana Gas funded its portion of
         the acquisition with $188,460 of intercompany borrowings from VUHI and
         $29,621 of commercial paper.

3.   Pro Forma Adjustments to Income Statements

(a)      Pro forma adjustment to reflect Indiana Gas' 47 percent ownership
         interest in the acquired net assets. For the purpose of these pro forma
         income statements, 47 percent of the net income of Dayton Power and
         Light Company's natural gas retail distribution business has been
         reflected as the equity in VEDO's net income.

(b)      Pro forma adjustment to reflect the interest expense on debt required
         to fund Indiana Gas' ownership interest in the acquired net assets.
         Short-term debt of $218,081 was borrowed at a rate of approximately 6.0
         percent per annum based upon Indiana Gas' composite average short-term
         borrowing rate at the date of the Acquisition (see 2C above).

(c)      Pro forma adjustment to reflect the income tax benefit of the interest
         expense on a combined federal and state statutory rate of 35 percent.

(d)      Pro forma adjustment to reflect Indiana Gas' equity in the amortization
         of the goodwill, net of tax. Recorded goodwill of $199,600 will be
         amortized over a period of 40 years.
