RESULTS OF OPERATIONS


                   EXECUTIVE SUMMARY OF RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with the
unaudited condensed financial statements and notes thereto and the quarterly
reports filed on Form 10-Q of both Vectren and VUHI.

Earnings for the second quarter of 2004 were $7.2 million compared to $6.9
million for the same quarter last year. The $0.3 million increase was primarily
due to the return on additional NOx related environmental expenditures and
weather, offset by results from wholesale power activities and increased
maintenance costs. Earnings were $17.3 million for the six months ended June 30,
2004, compared to $19.4 million in the prior year. The $2.1 million decrease was
primarily due to lower margins from wholesale power activities and increased
maintenance costs. This decrease was partially offset by the return on
additional NOx related expenditures and increased electric customer usage. The
Company estimates that weather favorably impacted second quarter earnings by
approximately $2.4 million after tax and year-to-date results by $1.5 million
after tax.

The Company generates revenue primarily from the delivery of natural gas and
electric service to its customers. The primary source of cash flow results from
the collection of customer bills and the payment for goods and services procured
for the delivery of gas and electric services. The results are impacted by
weather patterns in its service territory and general economic conditions both
in its service territory as well as nationally.

Vectren has in place a disclosure committee that consists of senior management
as well as financial management. The committee is actively involved in the
preparation and review of SIGECO's parent companies' SEC filings.

SIGNIFICANT FLUCTUATIONS

Margin

Margin generated from the sale of natural gas and electricity to small customers
(generally residential and commercial customers) is seasonal and impacted by
weather patterns in its service territory. Margin generated from sales to large
customers (generally industrial and other contract and firm wholesale customers)
is impacted by overall economic conditions. Margin is also impacted by the
collection of state mandated taxes which fluctuate with gas costs and also some
level of price sensitive fluctuation in volumes sold. Electric generating asset
optimization activities are primarily affected by market conditions, the level
of excess generating capacity, and electric transmission availability. Following
is a discussion and analysis of margin generated from regulated utility
operations.

Retail & Firm Wholesale Margin

Electric retail and firm wholesale utility margins were $60.2 million and $114.7
million for the three and six months ended June 30, 2004. This represents an
increase over the same period last year of $13.4 million and $17.7 million,
respectively. Margins increased $3.9 million quarter over quarter and $7.6
million for the six month periods due to an increase in retail electric rates
related to the recovery of NOx related expenditures. Excluding the effects of
NOx recovery, margins from industrial customers increased $1.8 million for the
quarter and $2.8 million for the year to date over 2003, which reflects some
economic recovery. Margin from small customers (excluding the effects of NOx)
increased over $8 million for both the quarter and year to date due to weather
and increased usage. Weather for the quarter was 20% warmer than normal and 111%
warmer than last year. Weather for the six months was also 20% warmer than
normal and 114% warmer than last year. The estimated increase in margin due to
weather was $4.0 million and $3.3 million for the three and six month periods,
respectively, compared to the prior year. Due to the above factors, volumes sold
increased 9% to 3.1 GWh for the six months ended June 30, 2004, compared to 2.8
GWh in 2003.

Margin from Asset Optimization Activities

Periodically, generation capacity is in excess of that needed to serve native
load and firm wholesale customers. The Company markets this unutilized capacity
to optimize the return on its owned generation assets. Substantially all of
these contracts are integrated with portfolio requirements around power supply
and delivery and are short-term purchase and sale transactions that expose the
Company to limited market risk.

         Following is a reconciliation of asset optimization activity:

Net wholesale margins declined $5.7 million and $6.8 million for the three and
six month periods as compared to last year. The decrease in margin both for the
quarter and year-to-date is due largely to less excess capacity. Increases in
demand by native load customers and scheduled outages of owned generation
related to the installation of environmental compliance equipment reduced the
availability of excess power, lowering wholesale margins.

Gas utility margins were $5.6 million and $15.8 million for the three and six
months ended June 30, 2004 and generally unchanged from the prior year.
Year-to-date heating weather was 5% warmer than normal and 11% warmer than last
year, causing a decline in margin of $0.7 million compared to the six months
ended June 30, 2003. Gas sold and transported volumes were 7% less in the six
months ended June 30, 2004, compared to the prior year. The decreased throughput
was primarily attributable to weather and partially offset by customer growth
and a 5% increase in volumes for contract customers for the second quarter 2004
compared to 2003. The average cost per dekatherm of gas purchased for the six
months ended June 30, 2004, was $6.00 compared to $5.90 in 2003.

OPERATING EXPENSES

Other operating

For the three and six months ended June 30, 2004, other operating expenses
increased $3.5 million and $7.5 million, respectively, compared to 2003. For the
quarter and year-to-date, additional NOx related operating expenses were $1.6
million and $2.2 million, respectively. For the quarter and year-to-date,
maintenance increases were $1.7 million and $2.0 million, respectively, due
primarily to planned turbine maintenance. Both the quarterly and year-to-date
periods are also affected by higher labor and benefit costs and increased
corporate charges for use of assets. Year-to-date bad debt expense is $0.8
million higher than the prior year.

Depreciation & amortization

For the three and six months ended June 30, 2004, depreciation and amortization
expenses increased $1.5 million and $6.4 million, respectively, compared to
2003. For the quarter and year-to-date, additional NOx related depreciation was
$0.6 million and $1.9 million, respectively. The year-to-date increase also
includes $3.6 million of additional depreciation resulting from a true-up of
demand side management amortization to existing regulatory orders recorded in
the first quarter of 2004. Remaining increases are primarily due to normal
additions to utility plant.

Taxes other than income taxes

For the three and six months ended June 30, 2004, taxes other than income taxes
increased $0.4 million and $0.6 million, respectively, compared to 2003. The
quarter and year-to-date increases are primarily attributable to higher utility
receipts taxes on higher electric sales, compared to the prior year.

Income Taxes

For the three months ended June 30, 2004, income taxes increased $2.2 million
compared to 2003, and year-to-date have decreased $1.1 million, primarily due to
fluctuation in income before taxes.

Total Other Income-Net

For the three and six months ended June 30, 2004, total other income (expense)
increased $0.3 million and $0.6 million, respectively, compared to 2003. The
increase was primarily attributable to charges in the second quarter of 2003
associated with the Culley settlement with the USEPA totaling $0.6 million.
