ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

The following discussion and analysis should be read in conjunction with the
consolidated financial statements and notes thereto:

                           Description of the Business

Vectren Corporation (Vectren) is an Indiana corporation that was organized on
June 10, 1999, solely for the purpose of effecting the merger of Indiana Energy,
Inc. (Indiana Energy) and SIGCORP, Inc. (SIGCORP). On March 31, 2000, the merger
of Indiana Energy with SIGCORP and into Vectren was consummated with a tax-free
exchange of shares and has been accounted for as a pooling of interests. The
common shareholders of SIGCORP received one and one-third shares of Vectren
common stock for each SIGCORP common share and the common shareholders of
Indiana Energy received one share of Vectren common stock for each Indiana
Energy common share, resulting in the issuance of 61.3 million shares of Vectren
common stock. The preferred stock and debt securities of Indiana Energy's and
SIGCORP's utility subsidiaries were not affected by the merger.

Vectren is a public utility holding company, whose wholly owned subsidiary,
Vectren Utility Holdings, Inc. (VUHI), is the intermediate holding company for
Vectren's three operating public utilities, Indiana Gas Company, Inc. (Indiana
Gas), formerly a wholly owned subsidiary of Indiana Energy, Southern Indiana Gas
and Electric Company (SIGECO), formerly a wholly owned subsidiary of SIGCORP,
and the Ohio operations (defined hereafter). VUHI's regulated subsidiaries serve
approximately one million customers. Indiana Gas and its subsidiaries provide
natural gas and transportation services to a diversified base of customers in
311 communities in 49 of Indiana's 92 counties. SIGECO provides generation,
transmission, distribution and the sale of electric power to Evansville,
Indiana, and 74 other communities, and the distribution and sale of natural gas
to Evansville, Indiana, and 64 communities in ten counties in southwestern
Indiana. Vectren's Ohio operations provide natural gas distribution and
transportation services to Dayton, Ohio and 16 counties in west central Ohio.

Vectren is involved in non-regulated activities through three primary business
groups: Energy Services, Utility Services, and Communications. Energy Services
trades and markets natural gas and provides energy performance contracting
services. Utility Services provides utility products and services, such as
underground construction and facilities locating, meter reading and materials
management, and the mining and sale of coal. Communications provides integrated
broadband communications services, including local and long distance telephone,
Internet access and cable television. In addition, other businesses invest in
other energy-related opportunities and corporate technology.

  Acquisition of Gas Distribution Assets of The Dayton Power and Light Company

On December 15, 1999, Indiana Energy, now Vectren, announced that the board of
directors had approved a definitive agreement under which it would acquire the
natural gas distribution assets of The Dayton Power and Light Company, which
would add 310,000 gas distribution customers in 16 counties in west central
Ohio. On October 31, 2000, Vectren completed the approximate $465 million
acquisition. Vectren acquired the natural gas distribution assets as a tenancy
in common through two wholly owned subsidiaries. Vectren Energy Delivery of
Ohio, Inc. (VEDO) holds a 53 percent undivided ownership interest in the assets


 3

and Indiana Gas holds a 47 percent undivided ownership interest in the assets.
VEDO is the operator of the assets, operations of which are herein referred to
as "the Ohio operations." VUHI established a $435 million commercial paper
program to fund the majority of the acquisition. This facility was utilized at
October 31, 2000, and will be replaced over time with permanent financing.
VEDO's portion of the acquisition was funded with short-term borrowings from
VUHI. Indiana Gas' portion of the acquisition was funded with a combination of
short-term borrowings from VUHI and its commercial paper program.

                              Common Stock Offering

On January 19, 2001, Vectren filed a registration statement with the Securities
and Exchange Commission with respect to a public offering of 5.5 million shares
of new common stock. On February 8, 2001, the registration became effective and
agreement was reached to sell 5.5 million shares to a group of underwriters. On
February 14, the shares were sold, at which time the underwriters exercised
their over-allotment option to sell an additional 825,000 shares for a total of
about 6.3 million shares. The net proceeds of $129.4 million will be used
principally to repay outstanding commercial paper utilized for recent
acquisitions.

                               Recent Development

In March 2001, Vectren, Indiana Gas, and SIGECO reached agreement with the
Indiana Office of Utility Consumer Counselor (OUCC) and The Citizens Action
Coalition of Indiana, Inc. (CAC) regarding an Indiana Utility Regulatory
Commission (IURC) Order disallowing Indiana Gas the recovery of $3.8 million in
gas costs. Vectren recorded a $3.8 million reduction of 2000 fourth quarter
revenues as a result of the disallowance.

As part of the agreement, among other things, the company agreed to contribute
additional funds to the state of Indiana's Low Income Heating Assistance Program
in 2001 and to credit $3.3 million of the $3.8 million disallowed amount to
Indiana Gas customers' April 2001 utility bills in exchange for both the OUCC
and the CAC dropping their appeals of the IURC Order. The contributions to
Indiana's Low Income Heating Assistance Program totaling $1.9 million were made
in 2001 and were charged to operations and maintenance expense. There was no
impact to 2000 operations as a result of this contribution.

For further information on the $3.8 million disallowance refer to Rate and
Regulatory Matters below. For further information on the settlement refer to
Vectren's Current Report on Form 8-K dated March 29, 2001.

                              Results of Operations

Vectren's consolidated earnings result from the operations of its utility
subsidiaries, Indiana Gas, SIGECO and the Ohio operations, and from the
non-utility operations and investments of Vectren's non-regulated businesses.

Net Income

Consolidated net income was $72.0 million, or $1.18 on a basic earnings per
share basis, for the year ended December 31, 2000. Consolidated net income
before merger and integration costs of $52.5 million, including $11.4 million of
additional depreciation included in depreciation and amortization (see merger
and integration costs below), was $108.8 million, or $1.78 per share, for the
year ended December 31, 2000, as compared to net income of $90.7 million, or
$1.48 per share, and $86.6 million, or $1.41 per share, for 1999 and 1998,
respectively. Vectren's 2000 results reflect two months of results of the Ohio
operations.

Dividends

On October 28, 2000, Vectren's board of directors increased the quarterly
dividend on common stock to 25.5 cents per share from 24.25 cents per share.
This resulted in total dividends paid of 98 cents compared to 94 cents in 1999.
In 1998, dividends paid totaled 90 cents per share.

Utility Margin (Utility Operating Revenues Less Utility Cost of Gas, Cost of
Fuel for Electric Generation and Purchased Electric Energy)

Vectren's utility gas margin increased $33.1 million to $266.2 million compared
to the twelve-month period in 1999, $28.2 million of the increase reflected the
inclusion of the Ohio operations' results for two months. The remaining $4.9
million, or 2 percent, increase attributable to Indiana Gas and SIGECO gas
operations reflects 8 percent (11.9MMDth) greater throughput (combined sales and
transportation) due to much colder temperatures during the fourth quarter of
2000 than the 1999 period and a 2 percent growth in customers. Residential and
commercial sales rose 7 percent and 10 percent, respectively. Temperatures were
11 percent colder during the current twelve-month period and approached normal
for the year. These favorable impacts on gas margin were partially offset by a
$3.8 million disallowance of recoverable gas costs by the IURC, charged against
gas revenues in December 2000 (see Rate and Regulatory Matters).

In 1999, gas utility margin was $233.1 million, as compared to $217.3 million
for the prior year. The 1999 increase is primarily attributable to weather being
8 percent colder than the same period in 1998 and the addition of new
residential and commercial customers.

Vectren's utilities' rates for gas transportation generally provide for the same
margins as are earned on the sale of gas under their applicable sales tariffs.
Approximately one-half of total gas system throughput represents gas used for
space heating and is affected by weather.

Total cost of gas sold was $552.5 million in 2000, $266.4 million in 1999 and
$270.0 million in 1998. Excluding $83.2 million related to the Ohio operations
for two months, total cost of gas sold increased $202.9 million, or 76 percent,
for the year ended December 31, 2000 compared to 1999, primarily due to


 5

significantly higher average per unit purchased gas costs. The total average
cost per dekatherm of gas purchased by Indiana Gas and SIGECO was $5.77 in 2000
compared to $3.58 in 1999. The price changes are due primarily to changing
commodity costs in the marketplace. Lower average per unit costs of gas sold
during 1999 as compared to 1998 more than offset the impact of the increased
throughput, causing the slight decline in 1999 cost of gas sold. Vectren's
utility subsidiaries are generally allowed full recovery of such changes in
purchased gas costs from their retail customers through commission-approved gas
cost adjustment mechanisms. (see Rate and Regulatory Matters).

Electric margin rose $8.3 million, or 4 percent, to $228.8 million for the
twelve-month period in 2000 compared to the same period in 1999. Although unit
prices were lower than in 1999, sales to the wholesale energy markets
contributed $4.4 million of the margin increase with volumes up 39 percent for
2000 compared to 1999. Additionally, the impact of much colder temperatures on
electric heating sales and a 5 percent growth in commercial customers
contributed to the 2000 electric margin increase. Mild summer temperatures
impacted both 2000 and 1999. Retail and firm wholesale electric sales for 2000
increased 2 percent and total electric sales increased 8 percent.

Electric utility margin for the year ended December 31, 1999 was $220.5 million,
compared to $211.9 million for the prior year. The $8.6 million increase in
margin reflects a 5 percent increase in retail and firm wholesale electric sales
primarily due to stronger industrial and commercial sales and a $1.0 million
increase in margin from sales to other wholesale customers. Although sales to
other wholesale customers declined 17 percent in 1999 due to milder summer
temperatures which eased demand in these markets, several new sales contracts
produced higher average unit sales prices to these customers.

A 1 percent increase in electric generation and higher per unit coal costs
resulted in a $4.9 million, or 7 percent, increase in fuel costs for electric
generation for 2000 compared to the prior year. Fuel costs for electric
generation increased $1.1 million, or 2 percent, in 1999.

Although SIGECO's sales of electric energy to other wholesale customers are
provided primarily from otherwise unutilized capacity, SIGECO's purchases of
electricity from other utilities for resale to other wholesale customers
typically represent the majority of SIGECO's total purchased electric energy
costs. The 39 percent increase in sales to other wholesale customers combined
with higher average market prices caused purchased electric energy costs to
increase $15.6 million, or 75 percent, for the year ended December 31, 2000
compared to 1999. During 1999, total purchases of electric energy declined 13
percent due to the 17 percent decline in sales to wholesale customers, however
higher average market prices for energy purchased resulted in total costs
remaining comparable to 1998 costs.

Non-Utility Margin (Energy Services and Other Revenues Less Cost of Energy
Services and Other)


Total margin from Vectren's non-utility operations (primarily the operating
companies of its Energy Services, Utility Services, and Communications groups)
for the twelve month period in 2000 was $20.3 million compared to $13.7 million
and $10.1 million for the same periods in 1999 and 1998, respectively. The $6.6
million increase in 2000 and $3.6 million increase in 1999 were primarily from
the Energy Services group reflecting the continued growth of its natural gas
marketing operations and its performance contracting and energy efficiency
project operations, including several large government contracts in progress.
Energy Services' margin increased $3.6 million and $3.7 million for 2000 and
1999, respectively. Expanded coal mining operations at Utility Services and


 6

additional municipal projects at Communications also contributed an additional
$2.5 million to the rise in 2000 non-utility margin.

During 2000, the cost of energy services and other, which was chiefly the cost
of natural gas purchased for resale by Energy Services and project contract
costs at Energy Services and Communications, rose $225.7 million, or 91 percent,
compared to 1999 due primarily to significantly higher per unit purchased gas
costs and growth in gas sales at Energy Services, following $45.1 million higher
costs in 1998.

Operating Expenses (excluding Cost of Gas Sold, Cost of Fuel for Electric
Generation, Purchased Electric Energy and Cost of Energy Services and Other)

Excluding $7.1 million in expenses related to the Ohio operations, Vectren's
other operating expenses increased $2.9 million, or less than 2 percent, for the
year ended December 31, 2000, compared to the same period in 1999. The increase
is attributable to higher operating expenses related to continued growth in
operations at certain non-regulated subsidiaries, primarily Energy Services.
Other operating expenses rose $7.8 million, or 4 percent, for 1999 as compared
to 1998. This increase reflects greater other general operating expenses at
Vectren's utility subsidiaries, including expenses associated with the new
customer information and work management systems and rental expense related to
buildings previously owned. Higher other operating expenses were also
experienced at Energy Services and Communications due to the continuing growth
in their operations.

Depreciation and amortization increased $18.7 million, or 21 percent, and $5.4
million, or 7 percent, for the years ended December 31, 2000 and December 31,
1999, respectively. The increase in 2000 expense is chiefly the result of
additional depreciation related to merger integration activities (see below) and
$1.7 million of depreciation of utility plant and amortization of goodwill
related to the Ohio operations. Goodwill related to the acquisition of the Ohio
operations of approximately $198 million is being amortized on a straight-line
basis over a 40 year period. The remaining $5.6 million, or 6 percent, increase
in expense over 1999 and the increase in expense over 1998 reflects depreciation
of normal additions of utility plant at Indiana Gas and SIGECO.

Taxes other than income taxes rose $8.1 million, or 27 percent, during 2000 due
to $7.1 million related to the Ohio operations, primarily Ohio excise tax, and
increased $2.5 million, or 9 percent, in 1999 due to higher gross receipts and
property tax expense.

Merger and Integration Costs

Merger and integration costs incurred for the year ended December 31, 2000
totaled $41.1 million, including $1.8 million related to the integration of the
Ohio operations Vectren expects to realize net merger savings of nearly $200
million over the next ten years from the elimination of duplicate corporate and
administrative programs and greater efficiencies in operations, business
processes and purchasing. The continued merger integration activities, which
will contribute to the merger savings, will be substantially completed in 2001.

Of the $41.1 million of merger and integration costs incurred in 2000, accruals
were established at March 31, 2000 totaling $20.7 million. Of this amount, $5.5
million related to employee and executive severance costs, $13.1 million related
to transaction costs and regulatory filing fees, and the remaining $2.1 million
related to employee relocations that occurred prior to or coincident with the
merger closing. At December 31, 2000, the accrual remaining for such costs
totaled $1.8 million, all related to severance costs. Of the $41.1 million, the
remaining $20.4 million was expensed throughout the remainder of the year as


 7

expenses were incurred. Such expenses included $6.0 million related to sign
changes at all company facilities to display the Vectren name, changes to all
fleet vehicles to reflect the new corporate name and logo, and changes to
company stationery. An additional $13.9 million was incurred over the course of
the year for accounting fees resulting from merger related filing requirements,
consulting fees related to integration activities such as organization
structure, employee travel between company locations as part of integration
activities, internal labor of employees assigned to integration teams, investor
relations, communications activities, and certain benefit costs. In addition,
$0.5 million was recorded related to severance costs associated with the
integration of the Ohio operations.

During the merger planning process, approximately 135 positions were identified
for elimination. As of December 31, 2000, approximately 70 positions had been
vacated, with the remaining 65 positions to be eliminated in 2001

The integration activities experienced by the company included such things as
information system consolidation, process review and definition, organization
design and consolidation, and knowledge sharing.

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,
resulting in additional depreciation expense of approximately $11.4 million for
the year ended December 31, 2000.

In total, merger and integration costs were $52.5 million ($36.8 million after
tax), or $.60 on a basic earnings per share basis, in 2000.

Other Income

Equity in earnings of unconsolidated investments increased $2.4 million for the
year ended December 31, 2000, compared to the prior year. The increase in 2000
is due primarily to a $7.0 million pre-tax net gain related to the restructuring
of Communications' investment in SIGECOM. The increase was partially offset by
lower pre-tax earnings recognized from ProLiance Energy Services, LLC
(ProLiance), Energy Services' energy marketing joint venture, and lower other
investment earnings.

Equity in earnings of unconsolidated investments decreased $3.2 million for
1999, compared to 1998. The decrease in 1999 reflected lower pre-tax earnings
recognized from ProLiance.

Other-net increased $11.6 million for the year ended December 31, 2000, compared
to the prior year due primarily to increased interest income mainly from
Vectren's investments in structured finance and investment transactions,
including leveraged leases and increased capitalized interest on utility
construction expenditures.

Other-net increased 1.5 million for the year ended December 31, 1999, compared
to the prior year due primarily to increased leveraged lease income, partially
offset by less sales of emission allowance credits.

 8

Interest Expense

Interest expense for the twelve-month period in 2000 rose $14.3 million, or 33
percent, compared to 1999. The increase was due primarily to increased working
capital requirements resulting from extremely high natural gas prices,
additional debt required for Vectren's increased financial investment
activities, interest related to the financing of the acquisition of the Ohio
operations, and higher average interest rates on utility debt and short-term
borrowings than incurred during 1999. Interest expense increased $2.5 million to
$42.9 million for 1999, as compared to 1998, due to increased average debt
outstanding required primarily to fund Vectren's increased financial investment
activities and higher average interest rates on utility debt.

Income Taxes

Federal and state income taxes declined $11.5 million in 2000, compared to 1999
due primarily to $30.1 million lower pre-tax earnings and to additional tax
benefits realized from certain non-regulated investments, which were partially
offset by the non-deductibility of certain merger costs. Federal and state
income taxes increased $3.4 million, or 8 percent during 1999 compared to 1998
due primarily to higher pre-tax income in 1999 and the favorable impact on the
1998 effective tax rate of the liquidation of a leveraged lease investment.

                             Other Operating Matters

Acquisition of Miller Pipeline Corporation

On December 13, 2000, Reliant Services, LLC (Reliant), a 50 percent owned,
non-regulated utility services affiliate of Vectren and Cinergy Corporation
(Cinergy), purchased the common stock of Miller Pipeline Corporation from
NiSource, Inc. for $68.3 million. Vectren and Cinergy each contributed $16
million of equity, and the remaining $36.3 million was funded with 7-year
intermediate bank loans. Miller Pipeline Corporation is one of the nation's
premier natural gas distribution contractors with over 50 years of experience in
the construction industry, currently providing such services to Indiana Gas,
among other customers. The acquisition will expand Vectren's utility services
business by adding underground pipeline construction, replacement and repair to
existing utility services.

Vectren Advanced Communications (VAC), a wholly owned non-regulated subsidiary,
was formed to hold Vectren's investments in Utilicom Networks, LLC (Utilicom )
and related entities. Utilicom Networks is a provider of bundled communications
services through high capacity broadband networks, including high speed internet
service, cable television and telephone service. VAC has a 14 percent interest
in Class A units of Utilicom, which is accounted for using the equity method of
accounting.

In January 2000, VAC completed the restructuring of its investment in SIGECOM,
LLC (SIGECOM), which is a venture between VAC and Utilicom which provides
communications services to the greater Evansville, Indiana area. On January 28,
2000, affiliates of The Blackstone Group, a private equity fund, invested in
Class B units of Utilicom. In connection with the Blackstone Group investment,
VAC exchanged its 49 percent preferred equity interest in SIGECOM for $16.5
million of convertible subordinated debt of Utilicom and a 14 percent indirect
common equity interest in SIGECOM, which was valued at $6.5 million The debt is
convertible into Class A units of Utilicom at the option of VAC or upon the
event of a public offering of stock by Utilicom. The carrying value of VAC's 49%
preferred equity interest was $15 million prior to the exchange. The
consideration received by VAC in the exchange was valued based upon an


 9

investment bank analysis of the fair value of SIGECOM at the transaction date.
The investment restructuring resulted in a pre-tax gain of $8 million, which is
classified in equity in earnings in unconsolidated investments in the
accompanying Consolidated Statements of Income. For the year ended December 31,
2000, Vectren also recognized losses of $1 million to reflect its share of
Utilicom and SIGECOM's operating results. At December 31, 2000, VAC's equity
investment in SIGECOM-related entities was $8.2 million.

In December 2000, VAC invested an additional $8.1 million with Utilicom in the
form of convertible subordinated debt as part of Utilicom's plans to raise $600
million in capital to establish operating ventures in Indianapolis, Indiana and
Dayton, Ohio and to recapitalize the SIGECOM venture. Vectren is committed to
invest up to $100 million, inclusive of the $8.1 million already invested, in
the form of convertible subordinated debt, subject to Utilicom obtaining all
required funding. The debt is convertible into common equity interests in the
Indianapolis and Dayton ventures at the option of VAC or upon the event of a
public offering of stock by Utilicom. At December 31, 2000, VAC's investment in
convertible debt totals approximately $25 million and, upon conversion, VAC
would have up to a 31 percent interest in the Indianapolis and Dayton ventures
and up to a 10 percent interest in Utilicom, assuming completion of all required
funding.

Both the Indianapolis and Dayton projects have received all necessary regulatory
approvals and are in advanced stages of pre-engineering and pre-construction
planning. Pole attachment rights have been secured, and launch dates of early
2002 are expected.

Operation of Warrick Generating Station

On August 21, 2000, SIGECO announced that no later than April 18, 2001, ALCOA,
INC. (ALCOA) would begin operating the Warrick Generating Station. In 1956,
arrangements were made for SIGECO to operate the Warrick Generating Station as
an agent for ALCOA. Three generating units at the plant are owned by ALCOA.
SIGECO owns the fourth unit equally with ALCOA. The operating change will have
no impact on SIGECO's generating capacity and is not expected to have any
negative impact on Vectren's financial results. Additionally, SIGECO will retain
ALCOA as a wholesale power and transmission services customer. Transition of the
plant operations was completed in March 2001.

Realignment

Effective January 1, 2001, the utility operations were realigned into two
primary business units, Energy Delivery and Power Supply.

                              ProLiance Energy, LLC

ProLiance, a 50 percent owned, non-regulated, energy marketing affiliate of
Vectren, began providing natural gas and related services to Indiana Gas,
Citizens Gas and Coke Utility (Citizens Gas) and others effective April 1, 1996.
The sale of gas and provision of other services to Indiana Gas by ProLiance is
subject to regulatory review through the quarterly gas cost adjustment (GCA)
process administered by the IURC.

On September 12, 1997, the IURC issued a decision finding the gas supply and
portfolio administration agreements between ProLiance and Indiana Gas and
ProLiance and Citizens Gas to be consistent with the public interest and that
ProLiance is not subject to regulation by the IURC as a public utility. The
IURC's decision reflected the significant gas cost savings to customers obtained


 10

through ProLiance's services and suggested that all material provisions of the
agreements between ProLiance and the utilities are reasonable. Nevertheless,
with respect to the pricing of gas commodity purchased from ProLiance, the
pricing of fees paid by ProLiance to the utilities for the prospect of using
pipeline entitlements if and when they are not required to serve the utilities'
firm customers, and the pricing of fees paid by the utilities to ProLiance for
portfolio administration services, the IURC concluded that additional review in
the GCA process would be appropriate and directed that these matters be
considered further in the pending, consolidated GCA proceeding involving Indiana
Gas and Citizens Gas. The IURC has not yet established a schedule for conducting
these additional proceedings. Through a series of appeals, the order was finally
considered by the Indiana Supreme Court.

On September 22, 2000, the Indiana Supreme Court issued a decision affirming the
IURC's decision on ProLiance in all respects. However, until the three pricing
issues reserved by the IURC are resolved, Vectren will continue to reserve a
portion of its share of ProLiance earnings.

In August 1998, Indiana Gas, Citizens Gas and ProLiance each received a Civil
Investigative Demand (CID) from the United States Department of Justice
requesting information relating to Indiana Gas' and Citizens Gas' relationship
with and the activities of ProLiance. The Department of Justice issued the CID
to gather information regarding ProLiance's formation and operations, and to
determine if trade or commerce has been restrained. Indiana Gas has provided all
information requested and management continues to believe that there are no
significant issues in this matter.

Indiana Gas continues to record gas costs in accordance with the terms of the
ProLiance contract and Vectren continues to record its proportional share of
ProLiance's earnings. Pretax income of $5.4 million and $6.7 million was
recognized as ProLiance's contribution to earnings for the years ended December
31, 2000 and 1999, respectively. Earnings recognized from ProLiance are included
in equity in earnings of unconsolidated investments on the Consolidated
Statements of Income. At December 31, 2000 and 1999, Vectren has reserved
approximately $2.4 million and $1.7 million, respectively, of ProLiance's
earnings after tax pending resolution of the remaining issues. The reserve
represents 10% of ProLiance's pretax earnings and serves as management's best
estimate of potential exposure arising from the three pricing issues.

                              Environmental Matters

Clean Air Act

NOx SIP Call Matter. In October 1997, the United States Environmental Protection
Agency (USEPA) proposed a rulemaking that could require uniform nitrogen oxide
(NOx) emissions reductions of 85 percent by utilities and other large sources in
a 22-state region spanning areas in the Northeast, Midwest, Great Lakes,
Mid-Atlantic and South. This rule is referred to as the "NOx SIP call." The
USEPA provided each state a proposed budget of allowed NOx emissions, a key
ingredient of ozone, which requires a significant reduction of such emissions.
Under that budget, utilities may be required to reduce NOx emissions to a rate
of 0.15 lb/mmBtu below levels already imposed by Phase I and Phase II of the
Clean Air Act Amendments of 1990 (the Act). Midwestern states (the alliance)
have been working together to determine the most appropriate compliance strategy
as an alternative to the USEPA proposal. The alliance submitted its proposal,
which calls for a smaller, phased in reduction of NOx levels, to the USEPA and
the Indiana Department of Environmental Management (IDEM) in June 1998.


 11

In July 1998, Indiana submitted its proposed plan to the USEPA in response to
the USEPA's proposed new NOx rule and the emissions budget proposed for Indiana.
The Indiana plan, which calls for a reduction of NOx emissions to a rate of 0.25
lb/mmBtu by 2003, is less stringent than the USEPA proposal but more stringent
than the alliance proposal.

On October 27, 1998, USEPA issued a final rule "Finding of Significant
Contribution and Rulemaking for Certain States in the Ozone Transport Assessment
Group Region for Purposes of Reducing Regional Transport of Ozone," (63 Fed.
Reg. 57355). The final rule requires that 23 states and jurisdictions must file
revised state implementation plans (SIPs) with the USEPA by no later than
September 30, 1999, which was essentially unchanged from its October 1997,
proposed rule. The USEPA has encouraged states to target utility coal-fired
boilers for the majority of the reductions required, especially NOx emissions.
Northeastern states have claimed that ozone transport from midwestern states
(including Indiana) is the primary reason for their ozone concentration
problems. Although this premise is challenged by others based on various air
quality modeling studies, including studies commissioned by the USEPA, the USEPA
intends to incorporate a regional control strategy to reduce ozone transport.
The USEPA's final ruling is being litigated in the federal courts by
approximately ten midwestern states, including Indiana.

During the second quarter of 1999, the USEPA lost two federal court challenges
to key air-pollution control requirements. In the first ruling by the U.S.
Circuit Court of Appeals for the District of Columbia on May 14, 1999, the Court
struck down the USEPA's attempt to tighten the one-hour ozone standard to an
eight-hour standard and the attempt to tighten the standard for particulate
emissions, finding the actions unconstitutional. In the second ruling by the
same Court on May 25, 1999, the Court placed an indefinite stay on the USEPA's
attempts to reduce the allowed NOx emissions rate from levels required by the
Clean Air Act Amendments of 1990. The USEPA appealed both court rulings. On
October 29, 1999, the Court refused to reconsider its May 14, 1999 ruling.

On March 3, 2000, the D.C. Circuit of Appeals upheld the USEPA's October 27,
1998 final rule requiring 23 states and the District of Columbia to file revised
SIPs with the USEPA by no later than September 30, 1999. Numerous petitioners,
including several states, have filed petitions for rehearing with the U.S. Court
of Appeals for the District of Columbia in Michigan v. the USEPA. On June 22,
2000, the D.C. Circuit Court of Appeals denied petition for rehearing en banc
and lifted its May 25, 1999 stay. Following this decision, on August 30, 2000,
the D.C. Circuit Court of Appeals issued an extension of the SIP Call
implementation deadline, previously May 1, 2003, to May 31, 2004. On September
20, 2000, petitioners filed a Petition of Writ of Certiori with the United
States Supreme Court requesting review of the D.C. Circuit Court's March 3, 2000
Order. The Court has not yet ruled on the Petition for Certiorari. The USEPA
granted Section 126 Petitions filed by northeastern states that require named
sources in the eastern half of Indiana to achieve NOx reduction by May 1, 2003.
No SIGECO facilities are named in the Section 126 Petitions filed by
northeastern states, therefore SIGECO's compliance date remains May 31, 2004.

The proposed NOx emissions budget for Indiana stipulated in the USEPA's final
ruling requires a 36 percent reduction in total NOx emissions from Indiana. The
ruling, pending finalization of state rule making, could require SIGECO to lower
its system-wide emissions by approximately 70 percent. Depending on the level of
system-wide emissions reductions ultimately required, and the control technology
utilized to achieve the reductions, the estimated construction costs of the
control equipment could reach $160 million, which are expected to be expended
during the 2001-2004 period, and related additional operation and maintenance
expenses could be an estimated $8 million to $10 million, annually. No accrual
has been recorded by the company related to the NOx SIP Call matter. The rules


 12

governing NOx emissions, once finalized, are to be applied prospectively.

Mercury Emissions. Under the Act, the USEPA is required to study emissions from
power plants in order to determine if additional regulations are necessary to
protect public health. The USEPA reported its study to Congress in February
1998. That study concluded that of all toxic pollution examined, mercury posed
the greatest concern to public health. An earlier USEPA study concluded that the
largest single source of human-caused mercury pollution in the United States was
coal-fired power plants.

After completion of the study, the Act required the USEPA to determine whether
to proceed with the development of regulations. The USEPA announced that it had
affirmatively decided that mercury air emissions from power plants should be
regulated.

On December 14, 2000, the USEPA released a statement announcing that reductions
of mercury emissions from coal-fired plants will be required in the near future.
The USEPA has indicated they will propose regulations by December 2003 and will
begin developing those regulations shortly. Industry, the public, and state,
local and tribal governments will have an opportunity to participate in the
process. The USEPA will then issue final regulations by December 2004. Because
rules governing mercury emissions are under development, the determination of
exposure, if any, is impossible as there are no standards or rules by which
compliance (or lack thereof) can be measured. Accordingly, no accrual has been
recorded by the company related to the mercury emissions matter.


Culley Generating Station Investigation Matter. The USEPA initiated an
investigation under Section 114 of the Act of SIGECO's coal-fired electric
generating units in commercial operation by 1977 to determine compliance with
environmental permitting requirements related to repairs, maintenance,
modifications and operations changes. The focus of the investigation was to
determine whether new source performance standards should be applied to the
modifications and whether the best available control technology was, or should
have been, used. Numerous other electric utilities were, and are currently,
being investigated by the USEPA under an industry-wide review for similar
compliance. SIGECO responded to all of the USEPA's data requests during the
investigation. In July 1999, SIGECO received a letter from the Office of
Enforcement and Compliance Assurance of the USEPA discussing the industry-wide
investigation, vaguely referring to the investigation of SIGECO and inviting
SIGECO to participate in a discussion of the issues. No specifics were noted;
furthermore, the letter stated that the communication was not intended to serve
as a notice of violation. Subsequent meetings were conducted in September and
October with the USEPA and targeted utilities, including SIGECO, regarding
potential remedies to the USEPA's general allegations.

On November 3, 1999, the USEPA filed a lawsuit against seven utilities,
including SIGECO. The USEPA alleges that, beginning in 1992, SIGECO violated the
Act by: (i) making modifications to its Culley Generating Station in Yankeetown,
Indiana without obtaining required permits; (ii) making major modifications to
the Culley Generating Station without installing the best available emission
control technology; and (iii) failing to notify the USEPA of the modifications.
In addition, the lawsuit alleges that the modifications to the Culley Generating
Station required SIGECO to begin to comply with federal new source performance
standards.

SIGECO believes it performed only maintenance, repair and replacement activities
at the Culley Generating Station, as allowed under the Act. Because proper
maintenance does not require permits, application of the best available emission


 13

control technology, notice to the USEPA, or compliance with new source
performance standards, SIGECO believes that the lawsuit is without merit, and
intends to vigorously defend the lawsuit.

The lawsuit seeks fines against SIGECO in the amount of $27,500 per day per
violation. The lawsuit does not specify the number of days or violations the
USEPA believes occurred. The lawsuit also seeks a court order requiring SIGECO
to install the best available emissions technology at the Culley Generating
Station. If the USEPA is successful in obtaining an order, SIGECO estimates that
it would incur capital costs of approximately $40 million to $50 million
complying with the order. In the event that SIGECO is required to install
system-wide NOx emission control equipment, as a result of the NOx SIP call
issue, the majority of the $40 million to $50 million for best available
emissions technology at Culley Generating Station would be included in the $160
million expenditure previously discussed.

The USEPA has also issued an administrative notice of violation to SIGECO making
the same allegations, but alleging that violations began in 1977.

While it is possible that SIGECO could be subjected to criminal penalties if the
Culley Generating Station continues to operate without complying with the new
source performance standards and the allegations are determined by a court to be
valid, SIGECO believes such penalties are unlikely as the USEPA and the electric
utility industry have a bonafide dispute over the proper interpretation of the
Act. Accordingly, no accrual has been recorded by the company, and SIGECO
anticipates at this time that the plant will continue to operate while the
matter is being decided.

Information Request. On January 23, 2001, SIGECO received an information request
from the USEPA under Section 114(a) of the Act for historical operational
information on the Warrick and A.B. Brown generating stations. SIGECO plans to
provide all information requested, and management believes that no significant
issues will arise from this request.

Manufactured Gas Plants

In the past, Indiana Gas and others operated facilities for the manufacture of
gas. Given the availability of natural gas transported by pipelines, these
facilities have not been operated for many years. Under currently applicable
environmental laws and regulations, Indiana Gas, and the others, may now be
required to take remedial action if certain byproducts are found above the
regulatory thresholds at these sites.

Indiana Gas has identified the existence, location and certain general
characteristics of 26 gas manufacturing and storage sites for which it may have
some remedial responsibility. Indiana Gas has completed a remedial
investigation/feasibility study (RI/FS) at one of the sites under an agreed
order between Indiana Gas and the Indiana Department of Environmental Management
(IDEM), and a Record of Decision (ROD) was issued by IDEM in January 2000.
Although Indiana Gas has not begun an RI/FS at additional sites, Indiana Gas has
submitted several of the sites to IDEM's Voluntary Remediation Program (VRP) and
is currently conducting some level of remedial activities including groundwater
monitoring at certain sites where deemed appropriate and will continue remedial
activities at the sites as appropriate and necessary.

In conjunction with data compiled by expert consultants, Indiana Gas has accrued
the estimated costs for further investigation, remediation, groundwater
monitoring and related costs for the sites. While the total costs that may be
incurred in connection with addressing these sites cannot be determined at this


 14

time, Indiana Gas has accrued costs that it reasonably expects to incur totaling
approximately $20.3 million.

The estimated accrued costs are limited to Indiana Gas' proportionate share of
the remediation efforts. Indiana Gas has arrangements in place for 19 of the 26
sites with other potentially responsible parties, which serve to limit Indiana
Gas' share of response costs at these 19 sites to between 20 and 50 percent.

With respect to insurance coverage, as of December 31, 2000, Indiana Gas has
received and recorded settlements from all known insurance carriers in an
aggregate amount approximating its $20.3 million accrual.

Environmental matters related to manufactured gas plants have had no material
impact on earnings since costs recorded to date approximate PRP and insurance
settlement recoveries. While Indiana Gas has recorded all costs which it
presently expects to incur in connection with activities at these sites, it is
possible that future events may require some level of additional remedial
activities which are not presently foreseen.

                          New Accounting Pronouncement

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standard No. 133 "Accounting for Derivative Instruments and
Hedging Activities" (SFAS 133), which requires that every derivative instrument
be recorded on the balance sheet as an asset or liability measured at its fair
value and that changes in the derivative's fair value be recognized currently in
earnings unless specific hedge accounting criteria are met.

SFAS 133, as amended, is effective for fiscal years beginning after June 15,
2000 and must be applied to derivative instruments and certain derivative
instruments embedded in hybrid contracts that were issued, acquired or
substantively modified after December 31, 1998. Vectren has completed the
process of identifying all derivative instruments, determining fair market
values of these derivatives, designating and documenting hedge relationships,
and evaluating the effectiveness of those hedge relationships. As a result of
the successful completion of this process, Vectren adopted SFAS 133 as of
January 1, 2001.

SFAS 133 requires that as of the date of initial adoption, the difference
between the fair market value of derivative instruments recorded on the balance
sheet and the previous carrying amount of those derivatives be reported in net
income or other comprehensive income, as appropriate, as the cumulative effect
of a change in accounting principle in accordance with Accounting Principles
Board Opinion No. 20 "Accounting Changes."

A limited number of Vectren's contracts are defined as derivatives under SFAS
133. These derivatives are forward physical contracts for both the purchase and
sale of natural gas and electricity by its wholly owned gas marketing
subsidiary, SIGCORP Energy Services, Inc. (SES) and SIGECO, respectively, and an
interest rate swap.

SES's primary business is the buying and re-selling of physical natural gas to
the industrial market segment. SES manages its pricing risk by entering into
corresponding gas commodity contracts that ensure a reasonable matching of the
associated risk. In addition, SES utilizes gas storage facilities to ensure
operational as well as price risk management of its forward positions. Minimal
open positions in terms of price, volume and specified delivery locations do
occur and are managed by SES using the above instruments and through management


 15

reporting. These commodity contracts and gas storage facilities are for the
normal purchase and sale of natural gas and therefore do not require fair value
accounting under SFAS 133. SES also utilizes price swap agreements that are
accounted for under SFAS 133 to mitigate price risk related to certain forward
physical contracts. These derivatives have not been designated as hedges,
accordingly, the changes in market value will be recorded currently in earnings.
The mark to market impact of these derivatives has been reflected as part of the
transition adjustment recorded to earnings on January 1, 2001.

Derivatives used in the power marketing operations are used to effectively
manage the utilization of SIGECO's generation capability. These derivatives
include forward physical wholesale sales and purchases. The forward sales
contracts are generally used to sell the excess generation capacity of SIGECO
when demand conditions warrant this activity. These contracts are for the normal
purchase and sale of electricity and therefore do not require fair value
accounting under SFAS 133. The forward purchase contracts are entered into as
part of "buy-sell" transactions with other utilities and power marketers. These
contracts are derivatives and do not qualify for hedge accounting, accordingly,
they have been marked to market currently in earnings. The mark to market impact
of these derivatives has been reflected as part of the transition adjustment
recorded to earnings on January 1, 2001.

The interest rate swap is used to hedge the exposure to interest rate risk
associated with VUHI's $150 million floating rate notes that bear interest at
the three month US dollar LIBOR rate plus .75 percent that were issued on
December 28, 2000. The swap was entered into concurrently with the issuance of
the floating rate debt. Vectren has formally documented the hedging relationship
between the swap and floating rate debt as well as its risk management
objectives and strategies for undertaking each hedge transaction. The swap has
been designated as a cash flow hedge and the mark to market impact has been
reflected as part of the transition adjustment recorded to other comprehensive
income on January 1, 2001.

The cumulative impact of the adoption of SFAS 133 on January 1, 2001 is a gain
of approximately $6.3 million due to the derivatives used in power marketing
operations. The impact of the derivatives used by SES and the interest rate swap
was immaterial.


                           Rate and Regulatory Matters

As a result of the ongoing appeal of a generic order issued by the IURC in
August 1999 regarding guidelines for the recovery of purchased power costs,
SIGECO entered into a settlement agreement with the Indiana Office of Utility
Consumer Counselor (OUCC) that provides certain terms with respect to the
recoverability of such costs. The settlement, originally approved by the IURC on
August 9, 2000, has been extended by agreement through March 2002. Under the
settlement, SIGECO can recover the entire cost of purchased power up to an
established benchmark, and during forced outages, SIGECO will bear a limited
share of its purchased power costs regardless of the market costs at that time.
Based on this agreement, SIGECO believes it has significantly limited its
exposure to unrecoverable purchased power costs.

Commodity prices for natural gas purchases during the last six months of 2000
unexpectedly increased significantly, primarily due to the expectation of a
colder winter, which led to increased demand and tighter supplies. Vectren's
utility subsidiaries are allowed full recovery of such charges in purchased gas
costs from their retail customers through commission-approved gas cost
adjustment mechanisms, and margin on gas sales should not be impacted. In
2001,Vectren 's utility subsidiaries may experience higher working capital


 16

requirements, increased expenses, including unrecoverable interest costs and
uncollectibles, and possibly some level of price sensitive reduction in volumes
sold.

On October 11, 2000, Indiana Gas filed for approval of its regular quarterly
GCA. In early December, the IURC issued an interim order approving the request
by Indiana Gas for a GCA factor for December 2000. On January 4, 2001, the IURC
approved the January and February 2001 GCA as filed. The order also addressed
the claim by the 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 IURC found that
there should be a $3.8 million disallowance related to gas procurement for the
winter season. As a result, Indiana Gas recognized a pre-tax charge of $3.8
million in December 2000. Both Indiana Gas and the OUCC have appealed this
ruling. The Citizens Action Coalition of Indiana, Inc., a not for profit
consumer advocate, has also filed with the IURC a petition to intervene and a
notice of appeal of the order. (See Recent Development.)

                                   Competition

The utility industry has been undergoing dramatic structural change for several
years, resulting in increasing competitive pressures faced by electric and gas
utility companies. Increased competition may create greater risks to the
stability of utility earnings generally and may in the future reduce our
earnings from retail electric and gas sales. Currently, several states,
including Ohio, have passed legislation that allows electricity customers to
choose their electricity supplier in a competitive electricity market and
several other states are considering such legislation. At the present time,
Indiana has not adopted such legislation. Ohio regulation provides for choice of
commodity for all gas customers. Vectren plans to implement this choice for all
of its gas customers in Ohio by 2002. Indiana has not adopted any regulation
requiring gas choice except for large volume customers.

                         Liquidity and Capital Resources

Vectren's capitalization objective is 40-50 percent permanent capitalization.
This objective may have varied, and will vary, from time to time, depending on
particular business opportunities and seasonal factors that affect the company's
operation. Vectren's common equity component was 51 percent and 56 percent of
its total capitalization, including current maturities of long-term debt, at
December 31, 2000 and 1999, respectively. The common equity component of 51
percent at December 31, 2000 is expected to be reduced in 2001 upon the
refinancing of a substantial amount of short-term debt to long-term debt.

New construction, normal system maintenance and improvements, and information
technology investments needed to provide service to a growing customer base will
continue to require substantial expenditures. Additionally, during the four year
period 2001 through 2004, construction costs for NOx emissions control equipment
are estimated to total approximately $160 million. For the years ended December
31, 2000 and 1999, capital expenditures totaled $164.3 million and $132.2
million, respectively. The increase in capital expenditures for 2000 is related
primarily to the additional coal mine development costs at Utility Services.
Vectren's anticipated investments in non-regulated affiliates during the next
five years will also require funding. Capital expenditures and investments in
affiliates for the five year period 2001 - 2005 are as follows:

(1)  Includes expenditures for NOx compliance of approximately $40 million in
     2001, $30 million in 2002, $55 million in 2003 and $35 million in 2004.
(2)  Includes expenditures for an 80-megawatt gas combustion turbine generator
     of $20 million in 2001 and $13 million in 2002.
(3)  Includes expenditures for additional generation assets of approximately $40
     million in 2005.
(4)  Includes expenditures for corporate technology hardware and software of
     approximately $48 million in 2001.

During the five year period 2001 - 2005, maturities and sinking fund
requirements on long-term debt subject to mandatory redemption, in millions, are
$0.3 in 2001, $16.0 in 2003, $15.0 in 2004, and $38.0 in 2005.

At December 31, 2000, Vectren had $969 million of short-term borrowing capacity
for use in its utility and non-regulated operations, of which approximately $209
million was available.

Short-term cash working capital is required primarily to finance customer
accounts receivable, unbilled utility revenues resulting from cycle billing, gas
in underground storage, prepaid gas delivery services, capital expenditures and
investments until permanently financed. Short-term borrowings tend to be
greatest during the summer when accounts receivable and unbilled utility
revenues related to electricity are highest and gas storage facilities are being
refilled. During 2000, however, short-term borrowings related to working capital
requirements were greatest during the last six months of the year due to the
higher natural gas costs. On October 31, 2000, Vectren completed the acquisition
of the Ohio operations for a purchase price of approximately $465 million.
Commercial paper was issued to fund the purchase and will be replaced over time
with permanent financing.

Vectren's primary source of liquidity to fund working capital requirements has
been cash generated from operations, which totaled approximately $40.7 million,
$149.2 million and $156.6 million in 2000, 1999 and 1998 respectively. Cash from
operations decreased during 2000 as compared to 1999 by approximately $108.8
million. The decrease is primarily attributable to merger and integration costs
causing lower net income, increased recoverable fuel and natural gas costs and
increased working capital requirements resulting from higher natural gas costs.
The decrease in 1999 cash flow from operations as compared to 1998 of
approximately $7.4 million is primarily attributable to unfavorable changes in
working capital accounts offset by increased net income.

At December 31, 2000, Indiana Gas is not in compliance with the total
indebtedness to capitalization ratio contained in its back up credit facility
for its commercial paper program. The non-compliance resulted from the
indebtedness incurred to purchase its ownership interest in the Ohio operations.
A waiver on the Indiana Gas facility has been obtained to waive the
non-compliance through and including March 31, 2001. Vectren will provide an
equity investment in Indiana Gas to bring Indiana Gas into compliance. No amount
is outstanding under the back up facility.

On December 21, 2000, Vectren Capital Corporation, a wholly owned subsidiary
that provides financing for Vectren's non-regulated subsidiaries' operations and
investments, issued $78 million of private placement intermediate term notes to
three institutional investors. The issues and their terms are: $38.0 million,
due December 21, 2005, at 7.67 percent; $17.5 million, due December 21, 2007, at
7.83 percent; and $22.5 million, due December 21, 2010, at 7.98 percent. The
proceeds were used to repay outstanding short-term borrowings.

In December 2000, Indiana Gas filed a prospectus with the SEC with respect to
the issuance of $70 million in debt securities. On December 28, 2000, $20
million of 15-Year Insured Quarterly (IQ) Notes bearing interest at a rate of
7.15 percent per year and $50 million of 30-Year IQ Notes bearing interest at a
rate of 7.45 percent per year were issued. The 15-Year IQ Notes will mature on
December 15, 2015, and 30-Year IQ Notes will mature on December 16, 2030,
unless, in each case, redeemed prior to that date. Indiana Gas will have the
option to redeem the 15-Year IQ Notes, in whole or in part, from time to time on
or after December 15, 2004. Indiana Gas will have the option to redeem the
30-Year IQ Notes in whole or in part, from time to time on or after December 15,
2005. The net proceeds of the debt issuance were used to repay outstanding
commercial paper.

On December 28, 2000, VUHI issued $150 million in floating rate notes to repay
an equal amount of outstanding commercial paper utilized for the Ohio operations
acquisition. The notes bear interest at a rate equal to the three month US
dollar LIBOR rate plus .75 percent. Concurrently with the completion of this
financing, a floating rate to fixed rate swap was executed which in effect
resulted in a fixed rate of 6.64 percent on the notes.

On January 19, 2001, Vectren filed a registration statement with the Securities
and Exchange Commission with respect to a public offering of 5.5 million shares
of new common stock. On February 8, 2001, the registration became effective and
agreement was reached to sell 5.5 million shares to a group of underwriters. On
February 14, the shares were sold, at which time the underwriters exercised
their over-allotment option to sell an additional 825,000 shares for a total of
6.3 million shares. The net proceeds of $129.4 million will be used principally
to repay outstanding commercial paper utilized for recent acquisitions.

On March 1, 2000, the interest rate on $31.5 million of Adjustable Rate
Pollution Control Bonds of SIGECO, due March 1, 2025, was changed from 3.00
percent to 4.30 percent. The new interest rate was fixed through February 28,
2001. Also on March 1, 2000, the interest rate on $22.2 million of Adjustable
Rate Pollution Control Bonds of SIGECO, due March 1, 2020, was changed from 3.05
percent to 4.45 percent. The new interest rate was also fixed through February
28, 2001. For financial statement presentation, the $53.7 million of Adjustable
Rate Pollution Control Bonds are shown as a current liability. The two series of
bonds will be re-set for a five-year period effective March 1, 2001.


                              Financing Activities

Vectren expects the majority of its utility capital expenditures requirements
and debt security redemptions to be provided by internally generated funds.

Indiana Gas' and SIGECO's credit ratings on outstanding debt at December 31,
2000 were A/A2 and A/A1, respectively. VUHI's commercial paper related to the


 19

October 2000 the Ohio operations acquisition has a credit rating of A-1/P-2.
Indiana Gas' commercial paper retains an A-1/P-1 rating.

Cash flow from financing activities of $638.7 million for the year ended
December 31, 2000 includes $697.0 million of additional net borrowings offset by
$60.0 million of dividends on shares of common stock. This is an increase of
$576.5 million over prior year due primarily to funding the acquisition of the
Ohio operations and increased working capital requirements.

Cash required for investing activities of $681.5 million for the year ended
December 31, 2000 includes, among other things, $463.3 million required for the
Ohio operations acquisition, $164.3 million of capital expenditures and $32.0
million additional notes receivable. This is an increase of $480.1 million over
prior year due primarily to the Ohio operations acquisition.

                  VECTREN CORPORATION AND SUBSIDIARY COMPANIES

                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

                           DECEMBER 31, 2000 AND 1999



1.   Organization and Nature of Operations

Vectren Corporation (Vectren) is an Indiana corporation that was organized on
June 10, 1999 solely for the purpose of effecting the merger of Indiana Energy,
Inc. (Indiana Energy) and SIGCORP, Inc. (SIGCORP). On March 31, 2000, the merger
of Indiana Energy with SIGCORP and into Vectren was consummated with a tax-free
exchange of shares and has been accounted for as a pooling-of-interests. The
common shareholders of SIGCORP received one and one-third shares of Vectren
common stock for each SIGCORP common share and the common shareholders of
Indiana Energy received one share of Vectren common stock for each Indiana
Energy common share, resulting in the issuance of 61.3 million shares of Vectren
common stock. The preferred stock and debt securities of Indiana Energy's and
SIGCORP's utility subsidiaries were not affected by the merger.

Vectren is a public utility holding company, whose wholly owned subsidiary,
Vectren Utility Holdings, Inc. (VUHI), is the intermediate holding company for
Vectren's three operating public utilities, Indiana Gas Company, Inc. (Indiana
Gas), formerly a wholly owned subsidiary of Indiana Energy, Southern Indiana Gas
and Electric Company (SIGECO), formerly a wholly owned subsidiary of SIGCORP,
and the Ohio operations (defined hereafter). Indiana Gas and its subsidiaries
provide natural gas and transportation services to a diversified base of
customers in 311 communities in 49 of Indiana's 92 counties. SIGECO provides
generation, transmission, distribution and the sale of electric power to
Evansville, Indiana, and 74 other communities, and the distribution and sale of
natural gas to Evansville, Indiana, and 64 communities in ten counties in
southwestern Indiana. The Ohio operations provide natural gas distribution and
transportation services to Dayton, Ohio and 16 counties in west central Ohio.

Vectren is involved in non-regulated activities through three primary business
groups: Energy Services, Utility Services and Communications. Energy Services
trades and markets natural gas and provides energy performance contracting
services. Utility Services provides utility products and services, such as
underground construction and facilities locating, meter reading and materials
management, and the mining and sale of coal. Communications provides integrated
broadband communications services, including local and long distance telephone,
Internet access and cable television. In addition, other businesses invest in
other energy-related opportunities and corporate technology.


2.   Acquisition of the Natural Gas Distribution Assets of The Dayton Power and
     Light Company

On October 31, 2000, Vectren acquired the natural gas distribution assets of The
Dayton Power and Light Company (DP&L) for approximately $465 million. The
acquisition has been accounted for as a purchase transaction in accordance with
Accounting Principles Board (APB) Opinion No. 16 and accordingly, the results of
operations of the acquired businesses are included in the accompanying financial
statements since the date of acquisition.

Vectren acquired the natural gas distribution assets as a tenancy in common
through two separate wholly owned subsidiaries. Vectren Energy Delivery of Ohio,
Inc. (VEDO) holds a 53 percent undivided ownership interest in the assets and
Indiana Gas holds a 47 percent undivided ownership interest. VEDO is the
operator of the assets, operations of which are referred to as "the Ohio
operations." VUHI established a $435 million commercial paper program to fund
the majority of the acquisition. This facility was utilized at October 31, 2000
and will be replaced over time with permanent financing. VEDO's portion of the
acquisition was funded with short-term borrowings from VUHI. Indiana Gas'
portion of the acquisition was funded with a combination of short-term
borrowings from VUHI and its commercial paper program.


 27

Goodwill has been recognized for the amount of the excess of the purchase price
paid over the book value of the net assets acquired and is being amortized on a
straight line basis over 40 years. Goodwill recognized as a result of the
acquisition is $198 million. The purchase price is subject to adjustment based
on the finalization of the closing balance sheet in accordance with the Asset
Purchase Agreement.

The following table depicts, for the years ended December 31, 2000 and 1999,
unaudited pro forma consolidated information, as if the acquisition of the Ohio
operations occurred on January 1, 1999. The pro forma summary information
presented below is not necessarily indicative of the results that actually would
have occurred if the transaction indicated above had been consummated at the
beginning of the periods presented and is not intended to be a projection of
future results.

3.   Merger and Integration Costs

Merger and integration costs incurred for the year ended December 31, 2000
totaled $41.1 million, including $1.8 million related to the integration of the
Ohio operations. The merger integration activities will be substantially
completed in 2001.

Of the $41.1 million of merger and integration costs incurred in 2000, accruals
were established at March 31, 2000 totaling $20.7 million. Of this amount, $5.5
million related to employee and executive severance costs, $13.1 million related
to transaction costs and regulatory filing fees, and the remaining $2.1 million
related to employee relocations that occurred prior to or coincident with the
merger closing. At December 31, 2000, the accrual remaining for such costs
totaled $1.8 million, all related to severance costs. Of the $41.1 million, the
remaining $20.4 million was expensed throughout the remainder of the year as
expenses were incurred. Such expenses included $6.0 million related to sign
changes at all company facilities to display the Vectren name, changes to all
fleet vehicles to reflect the new corporate name and logo, and changes to
company stationery. An additional $13.9 million was incurred over the course of
the year for accounting fees resulting from merger related filing requirements,
consulting fees related to integration activities such as organization
structure, employee travel between company locations as part of integration
activities, internal labor of employees assigned to integration teams, investor
relations communications activities, and certain benefit costs. In addition,
$0.5 million was recorded related to severance costs associated with the
integration of the Ohio operations.

During the merger planning process, approximately 135 positions were identified
for elimination. As of December 31, 2000, approximately 70 positions had been
vacated, with the remaining 65 positions to be eliminated in 2001

The integration activities experienced by the company included such things as
information system consolidation, process review and definition, organization
design and consolidation, and knowledge sharing.


 28

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,
resulting in additional depreciation expense of approximately $11.4 million
($7.1 million after tax) for the year ended December 31, 2000.

4.   Indiana Energy and SIGCORP Results (Prior to the Combination)

The results of the predecessor companies, Indiana Energy and SIGCORP, for the
three months ended March 31, 2000 and for the years ended December 31, 1999 and
1998 are as follows (in millions):

5.   Summary of Significant Accounting Policies

A.  Principles of Consolidation
The accompanying consolidated financial statements for the years ended December
31, 1999 and 1998 of Vectren and its subsidiary companies reflect the company on
a historical basis as restated for the effects of the pooling-of-interests
transaction completed on March 31, 2000 between Indiana Energy and SIGCORP. The
consolidated financial statements include the accounts of Vectren and its wholly
owned and majority owned subsidiaries, after elimination of intercompany
transactions. Investments in limited partnerships and less than majority-owned
affiliates are accounted for on the equity method. The financial statements also
reflect the consolidation of a majority-owned affiliate, Energy Systems Group,
LLC, which was an equity method investment of Indiana Energy and SIGCORP prior
to the merger.

B.  Investments in Partnerships and Other Corporations
Investments in partnerships and other corporations, which are more than 20
percent owned but less than majority owned, are generally accounted for by the
equity method. Vectren's share of net income or loss from these investments is
recorded in equity in earnings of unconsolidated affiliates. Dividends are
recorded as a reduction of the carrying value of the investment when received.

Investments in other corporations less than 20 percent owned are generally
carried at cost less writedowns for declines in value judged to be other than
temporary. Dividends are recorded as other income when received.

C.  Reclassifications
Certain reclassifications have been made to the prior years' financial
statements to conform to the current year presentation. These reclassifications
have no impact on net income previously reported.

D.  Utility Plant and Depreciation
Utility plant is stated at historical cost, including an allowance for the cost
of funds used during construction. Depreciation of utility property is provided
using the straight-line method over the estimated service lives of the
depreciable assets.

The original cost, together with depreciation rates expressed as a percentage of
original cost, for the components of utility plant were as follows":

Vectren follows the practice of charging maintenance and repairs, including the
cost of removal of minor items of property, to expense as incurred. When
property that represents a retirement unit is replaced or removed, the cost of
such property is credited to utility plant, and such cost, together with the
cost of removal less salvage, is charged to accumulated depreciation.


E.  Nonutility Plant
Nonutility plant consists of property and equipment used by Vectren's
non-regulated operations. The depreciation of nonutility plant is charged
against income over their estimated useful lives, using the straight-line method
of depreciation or units of production method of amortization. Repairs and
maintenance, which are not considered betterments and do not extend the useful
life of the nonutility plant, are charged to expense as incurred. When
nonutility plant is retired, or otherwise disposed of, the asset and accumulated
depreciation are removed and the resulting gain or loss is reflected in income.

Nonutility plant consists of the following:

F.   Cash Flow Information
For purposes of the Consolidated Statements of Cash Flows, Vectren considers
cash investments with an original maturity of three months or less to be cash
equivalents. Cash paid during the periods reported for interest, income taxes
and acquired assets and liabilities were as follows:

G.  Revenues
Revenues are recorded as products and services are delivered to customers. To
more closely match revenues and expenses, Vectren's utility subsidiaries record
revenues for all gas and electricity delivered to customers but not billed at
the end of the accounting period.


 30

Excise taxes are embedded in rates charged to customers. Accordingly, the
company records excise tax received as a component of operating revenues. Excise
taxes paid are recorded as a component of taxes other than income taxes.

H.  Inventories
Inventories primarily consist of gas in underground storage, fuel
for electric generation and materials and supplies. Gas in underground storage
at SIGECO and Indiana Gas is valued using last-in, first-out (LIFO) method,
while all other inventories, including the acquired inventories of the Ohio
operations, are valued using the average cost method. Based on the average cost
of gas purchased during December, the cost of replacing the current portion of
gas in underground storage exceeded LIFO cost at December 31, 2000 and 1999 by
approximately $64.3 million and $23.2 million, respectively. Inventories consist
of the following:

I.   Refundable or Recoverable Gas Costs, Fuel for Electric Production and
     Purchased Power
All metered gas rates contain a gas cost adjustment clause, which allows for
adjustment in charges for changes in the cost of purchased gas. Metered electric
rates typically contain a fuel adjustment clause that allows for adjustment in
charges for electric energy to reflect changes in the cost of fuel and the net
energy cost of purchased power. SIGECO also collects through a quarterly rate
adjustment mechanism the margin on electric sales lost due to the implementation
of demand side management programs.

Vectren's utility subsidiaries record any adjustment clause
under-or-overrecovery each month in revenues. A corresponding asset or liability
is recorded until such time as the under-or-overrecovery is billed or refunded
to utility customers. The cost of gas sold is charged to operating expense as
delivered to customers and the cost of fuel for electric generation is charged
to operating expense when consumed.

J.  Allowance for Funds used During Construction
An allowance for funds used during construction (AFUDC), which represents the
cost of borrowed and equity funds used for construction purposes, is charged to
construction work in progress during the period of construction and included in
other - net on the Consolidated Statements of Income.

The table below reflects the total AFUDC capitalized and the portion of which
was computed on borrowed and equity funds for all periods reported.

                          ======   ======   ======

K.  Income Taxes
The liability method of accounting is used for income taxes under which deferred
income taxes are recognized, at currently enacted income tax rates, to reflect
the tax effect of temporary differences between the book and tax bases of assets
and liabilities. Deferred investment tax credits are being amortized over the
life of the related asset.


 31

L.  Use of Estimates
The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from these estimates.

M.  Regulation
The utility operations of Indiana Gas and SIGECO are subject to regulation by
the Indiana Utility Regulatory Commission (IURC) and the Ohio operations are
subject to regulation by the Public Utilities Commission of Ohio (PUCO). The
wholesale energy sales of SIGECO are subject to regulation by the Federal Energy
Regulatory Commission (FERC). The accounting policies of Vectren and its utility
subsidiaries give recognition to the ratemaking and accounting practices of
these agencies and to accounting principles generally accepted in the United
States, including the provisions of Statement of Financial Accounting Standards
No. 71 "Accounting for the Effects of Certain Types of Regulation" (SFAS 71).
Regulatory assets represent probable future revenues associated with certain
incurred costs, which will be recovered from customers through the ratemaking
process. Regulatory liabilities represent probable future reductions in revenues
associated with amounts that are to be credited to customers through the
ratemaking process.

The following regulatory assets and liabilities are reflected in the financial
statements:

As of December 31, 2000, the recovery of $126.9 million of Vectren's $148.3
million of total regulatory assets is reflected in rates charged to customers.
The remaining $21.4 million of regulatory assets, which are not yet included in
rates, represent SIGECO's demand side management (DSM) costs incurred after
1993. When SIGECO files its next electric base rate case, these costs will be
included in rate base and requested to earn a return. Amortization of the costs
over a period anticipated to be 15 years will be recovered through rates as a
cost of operations. SIGECO is currently recovering $4.8 million of DSM costs in
rates. Based upon this prior regulatory authority, management believes that
future recovery of the $21.4 million of regulatory assets for DSM costs is
probable.

Indiana Gas was authorized as part of an August 17, 1994 financing order from
the IURC to amortize over a 15-year period the debt discount and expense related
to new debt issues and future debt issues and future premiums paid for debt
reacquired in connection with refinancing. Debt discount and expense for issues
in place prior to this order are being amortized over the lives of the related
issues. Premiums paid prior to this order for debt reacquired in connection with
refinancing are being amortized over the life of the refunding issue. SIGECO's
debt discounts and expense related to new debt issues and premiums paid for debt
reacquired is being amortized over the lives of the related issues.


 32

Of the $126.9 million of regulatory assets currently reflected in rates, a total
of $9.1 million is earning a return: $4.9 million of pre-1994 DSM costs and $4.2
million of unamortized premium on reacquired debt. The remaining recovery
periods for the DSM costs and premium on reacquired debt are 11.5 years and 20
years, respectively. The remaining $117.9 million of regulatory assets included
in rates, but not earning a return, are being recovered over varying periods:
$7.1 million of fuel costs and $89.0 million of gas costs, over 12 months; $4.7
million of regulatory income tax asset, over approximately 30 years; and $16.8
million of unamortized debt discount and expense to be recovered as discussed
above.

Vectren's utility subsidiaries' policy is to continually assess the
recoverability of costs recognized as regulatory assets and the ability to
continue to account for their activities in accordance with SFAS 71, based on
the criteria set forth in SFAS 71. Based on current regulation, the utility
subsidiaries believe such accounting is appropriate. If all or part of Vectren's
utility operations cease to meet the criteria of SFAS 71, a write-off of related
regulatory assets and liabilities would be required. In addition, Vectren would
be required to determine any impairment to the carrying costs of deregulated
plant and inventory assets.

N.  New Accounting Pronouncement
In June 1998, the Financial Accounting Standards Board issued SFAS No. 133
"Accounting for Derivative Instruments and Hedging Activities" (SFAS 133), which
requires that every derivative instrument be recorded on the balance sheet as an
asset or liability measured at its fair value and that changes in the
derivative's fair value be recognized currently in earnings unless specific
hedge accounting criteria are met.

SFAS 133, as amended, is effective for fiscal years beginning after June 15,
2000 and must be applied to derivative instruments and certain derivative
instruments embedded in hybrid contracts that were issued, acquired or
substantively modified after December 31, 1998. Vectren has completed the
process of identifying all derivative instruments, determining fair market
values of these derivatives, designating and documenting hedge relationships,
and evaluating the effectiveness of those hedge relationships. As a result of
the successful completion of this process, Vectren adopted SFAS 133 as of
January 1, 2001.

SFAS 133 requires that as of the date of initial adoption, the difference
between the fair market value of derivative instruments recorded on the balance
sheet and the previous carrying amount of those derivatives be reported in net
income or other comprehensive income, as appropriate, as the cumulative effect
of a change in accounting principle in accordance with APB 20, "Accounting
Changes."

A limited number of Vectren's contracts are defined as derivatives under SFAS
133. These derivatives are forward physical contracts for both the purchase and
sale of natural gas and electricity by its wholly owned gas marketing
subsidiary, SIGCORP Energy Services, Inc (SES) and SIGECO, respectively, and an
interest rate swap.

SES's primary business is the buying and re-selling of physical natural gas to
the industrial market segment. SES manages its pricing risk by entering into
corresponding gas commodity contracts that ensure a reasonable matching of the
associated risk. In addition, SES takes physical delivery of gas in storage
facilities to ensure operational as well as price risk management of its forward
positions. Open positions in terms of price, volume and specified delivery
locations do occur and are managed by SES using the above instruments and
through management reporting. These commodity contracts and gas storage
facilities involve the normal purchase and sale of natural gas and therefore do
not require fair value accounting under SFAS 133. SES also utilizes price swap
agreements that are accounted for under SFAS 133 to mitigate price risk related
to certain forward physical contracts. These derivatives have not been
designated as hedges, accordingly, the changes in market value will be recorded
currently in earnings. The mark to market impact of these derivatives has been
reflected as part of the transition adjustment recorded to earnings on January
1, 2001.

Derivatives used in the power marketing operations are used to effectively
manage the utilization of SIGECO's generation capability. These derivatives
include forward physical wholesale sales and purchases. The forward sales
contracts are generally used to sell the excess generation capacity of SIGECO
when demand conditions warrant this activity. These contracts are for the normal
purchase and sale of electricity and therefore do not require fair value
accounting under SFAS 133. The forward purchase contracts are entered into as


 33

part of "buy-sell" transactions with other utilities and power marketers. These
contracts are derivatives and do not qualify for hedge accounting, accordingly,
they have been marked to market currently in earnings. The mark to market impact
of these derivatives has been reflected as part of the transition adjustment
recorded to earnings on January 1, 2001.

The interest rate swap is used to hedge the exposure to interest rate risk
associated with VUHI's $150 million floating rate notes. The swap was entered
into concurrently with the issuance of the floating rate debt. Vectren has
formally documented the hedging relationship between the swap and floating rate
debt as well as its risk management objectives and strategies for undertaking
the hedging transaction. The swap has been designated as a cash flow hedge and
the mark to market impact has been reflected as part of the transition
adjustment recorded to other comprehensive income on January 1, 2001.

The cumulative impact of the adoption of SFAS 133 on January 1, 2001 is an
earnings gain of approximately $6.3 million due to the derivatives used in power
marketing operations. The impact of the derivatives used by SES and the interest
rate swap was immaterial.

O.  Comprehensive Income
Comprehensive income is a measure of all changes in equity of an enterprise
which result from the transactions or other economic events during the period
other than transactions with shareholders. This information is reported in the
Consolidated Statements of Common Shareholders' Equity. Vectren's components of
accumulated other comprehensive income (loss) include unrealized gains (losses)
on available for sale securities and its portion of ProLiance Energy, LLC's
(ProLiance) other comprehensive income. Vectren records its portion of
ProLiance's other comprehensive income as increases or decreases to the
investment account with a corresponding adjustment to other comprehensive
income. As of December 31, 2000, Vectren has recorded an adjustment to other
comprehensive income of $7.5 million related to its investment in ProLiance.
ProLiance's other comprehensive income was adjusted due its adoption of SFAS
133.

P.   Impairment Review of Long-Lived Assets
Long-lived assets are reviewed for impairment in accordance with SFAS No. 121,
Accounting for Impairment of Long-Lived Assets and for Long-Lived Assets to be
Disposed Of, as facts and circumstances indicate that the carrying amount may be
impaired. Specifically, the evaluation for impairment involves the comparison of
an asset's carrying value and the estimated undiscounted future cash flows the
asset is expected to generate over its remaining life. If this evaluation were
to conclude that the carrying value of the asset is impaired, an impairment
charge would be recorded as a charge to operations based on the difference
between the asset's carrying amount and its fair value.

6.   ProLiance Energy, LLC

ProLiance, a 50 percent owned, non-regulated, energy marketing affiliate of
Vectren, began providing natural gas and related services to Indiana Gas,
Citizens Gas and Coke Utility (Citizens Gas) and others effective April 1, 1996.
The sale of gas and provision of other services to Indiana Gas by ProLiance is
subject to regulatory review through the quarterly gas cost adjustment (GCA)
process administered by the IURC.

On September 12, 1997, the IURC issued a decision finding the gas supply and
portfolio administration agreements between ProLiance and Indiana Gas and
ProLiance and Citizens Gas to be consistent with the public interest and that
ProLiance is not subject to regulation by the IURC as a public utility. The
IURC's decision reflected the significant gas cost savings to customers obtained
through ProLiance's services and suggested that all material provisions of the
agreements between ProLiance and the utilities are reasonable. Nevertheless,
with respect to the pricing of gas commodity purchased from ProLiance, the
pricing of fees paid by ProLiance to the utilities for the prospect of using
pipeline entitlements if and when they are not required to serve the utilities'
firm customers, and the pricing of fees paid by the utilities to ProLiance for
portfolio administration services, the IURC concluded that additional review in
the GCA process would be appropriate and directed that these matters be
considered further in the pending, consolidated GCA proceeding involving Indiana
Gas and Citizens Gas. The IURC has not yet established a schedule for conducting


 34

these additional proceedings. Through a series of appeals, the order was finally
considered by the Indiana Supreme Court.

On September 22, 2000, the Indiana Supreme Court issued a decision affirming the
IURC's decision on ProLiance in all respects. However, until the three pricing
issues reserved by the IURC are resolved, Vectren will continue to reserve a
portion of its share of ProLiance earnings.

On or about August 11, 1998, Indiana Gas, Citizens Gas and ProLiance each
received a Civil Investigative Demand (CID) from the United States Department of
Justice requesting information relating to Indiana Gas' and Citizens Gas'
relationship with and the activities of ProLiance. The Department of Justice
issued the CID to gather information regarding ProLiance's formation and
operations, and to determine if trade or commerce has been restrained. Indiana
Gas has provided all information requested and management continues to believe
that there are no significant issues in this matter.

Indiana Gas continues to record gas costs in accordance with the terms of the
ProLiance contract and Vectren continues to record its proportional share of
ProLiance's earnings. Pretax income of $5.4 million, $6.7 million, and $7.0
million was recognized as ProLiance's contribution to earnings for the years
ended December 31, 2000, 1999 and 1998, respectively. Earnings recognized from
ProLiance are included in equity in earnings of unconsolidated investments on
the Consolidated Statements of Income. At December 31, 2000, and 1999, Vectren
has reserved approximately $2.4 million and $1.7 million, respectively, of
ProLiance's earnings pending resolution of the remaining issues. The reserve
represents 10% of ProLiance's pretax earnings and serves as management's best
estimate of potential exposure arising from the three pricing issues.

7.   Vectren Advanced Communications

Vectren Advanced Communications (VAC), a wholly owned non-regulated subsidiary,
was formed to hold Vectren's investments in Utilicom Networks, LLC (Utilicom )
and related entities. Utilicom Networks is a provider of bundled communications
services through high capacity broadband networks, including high speed internet
service, cable television and telephone service. VAC has a 14 percent interest
in Class A units of Utilicom, which is accounted for using the equity method of
accounting.

In January 2000, VAC completed the restructuring of its investment in SIGECOM,
LLC (SIGECOM), which is a venture between VAC and Utilicom which provides
communications services to the greater Evansville, Indiana area. On January 28,
2000, affiliates of The Blackstone Group, a private equity fund, invested in
Class B units of Utilicom. In connection with the Blackstone Group investment,
VAC exchanged its 49 percent preferred equity interest in SIGECOM for $16.5
million of convertible subordinated debt of Utilicom and a 14 percent indirect
common equity interest in SIGECOM, which was valued at $6.5 million The debt is
convertible into Class A units of Utilicom at the option of VAC or upon the
event of a public offering of stock by Utilicom. The carrying value of VAC's 49%
preferred equity interest was $15 million prior to the exchange. The
consideration received by VAC in the exchange was valued based upon an
investment bank analysis of the fair value of SIGECOM at the transaction date.
The investment restructuring resulted in a pre-tax gain of $8 million, which is
classified in equity in earnings in unconsolidated investments in the
accompanying Consolidated Statements of Income. For the year ended December 31,
2000, Vectren also recognized losses of $1 million to reflect its share of
Utilicom and SIGECOM's operating results. At December 31, 2000 and 1999, VAC's
equity investment in SIGECOM-related entities was $8.2 million and $16.1
million, respectively.

In December 2000, VAC invested an additional $8.1 million with Utilicom in the
form of convertible subordinated debt as part of Utilicom's plans to raise $600
million in capital to establish operating ventures in Indianapolis, Indiana and
Dayton, Ohio and to recapitalize the SIGECOM venture. Vectren is committed to
invest up to $100 million, inclusive of the $8.1 million already invested, in
the form of convertible subordinated debt, subject to Utilicom obtaining all
required funding. The debt is convertible into common equity interests in the
Indianapolis and Dayton ventures at the option of VAC or upon the event of a
public offering of stock by Utilicom. At December 31, 2000, VAC's investment in
convertible debt totals approximately $25 million and, upon conversion, VAC


 35

would have up to a 31 percent interest in the Indianapolis and Dayton ventures
and up to a 10 percent interest in Utilicom, assuming completion of all required
funding.

8.   Short-Term Borrowings

At December 31, 2000, Vectren has approximately $969 million of short-term
borrowing capacity, including $803 million for its regulated operations and $166
million for its non-regulated operations, of which approximately $149 million is
available for regulated operations and $60 million is available for
non-regulated operations. See the table below for outstanding balances and
interest rates.

At December 31, 2000, Indiana Gas is not in compliance with the total
indebtedness to capitalization ratio contained in its back up credit facility
for its commercial paper program. The non-compliance resulted from the
indebtedness incurred to purchase its ownership interest in the Ohio operations.
A waiver has been obtained from the banks on the Indiana Gas facility to waive
the non-compliance through and including March 31, 2001. Subject to regulatory
approval, Vectren will provide an equity investment in Indiana Gas to bring
Indiana Gas back into compliance. No amount is outstanding under the back up
credit facility.

Consolidated maturities and sinking fund requirements on long-term debt subject
to mandatory redemption during the five years following 2000 (in millions) are
$0.3 in 2001, $16.0 in 2003, $15.0 in 2004, and $38.0 in 2005.

In addition to the obligations presented in the table above, SIGECO has $53.7
million of adjustable rate pollution control series first mortgage bonds which
could, at the election of the bondholder, be tendered to SIGECO annually in
March. If SIGECO's agent is unable to remarket any bonds tendered at that time,
SIGECO would be required to obtain additional funds for payment to bondholders.


 37

For financial statement presentation purposes those bonds subject to tender in
2001 are shown as current liabilities. The two series of bonds will be re-set
for a five-year period effective March 1, 2001.

Provisions under which certain of Indiana Gas' Series E Notes were issued
entitle the holders of $25.0 million of these notes to put the debt back to
Indiana Gas at face value at certain specified dates before maturity. Long-term
debt subject to the put provisions during the five years following 2000 (in
millions) is $6.5 in 2002, $3.5 in 2004 and $10.0 in 2005.

The annual sinking fund requirement of SIGECO's first mortgage bonds is 1
percent of the greatest amount of bonds outstanding under the Mortgage
Indenture. This requirement may be satisfied by certification to the Trustee of
unfunded property additions in the prescribed amount as provided in the Mortgage
Indenture. SIGECO intends to meet the 2001 sinking fund requirement by this
means and, accordingly, the sinking fund requirement for 2001 is excluded from
current liabilities on the Consolidated Balance Sheets. At December 31, 2000,
$220.9 million of SIGECO's utility plant remained unfunded under SIGECO's
Mortgage Indenture.

The above debt agreements contain certain financial covenants and other
restrictions with which Vectren must comply. Except as described in Note 8,
Vectren was in compliance with all remaining financial covenants and
restrictions.

On December 21, 2000, Vectren Capital Corporation, a wholly owned subsidiary
that provides financing for Vectren's non-regulated subsidiaries' operations and
investments, issued $78 million of private placement senior notes to three
institutional investors. The issues and their terms are $38.0 million, due
December 21, 2005, at 7.67 percent; $17.5 million, due December 21, 2007, at
7.83 percent; and $22.5 million, due December 21, 2010, at 7.98 percent. The net
proceeds were used to repay outstanding short-term borrowings.

On October 5, 1999, Indiana Gas issued $30 million in principal amount of Series
G Medium-term Notes bearing interest at the per annum rate of 7.08 percent with
a maturity date of October 5, 2029. In December 2000, Indiana Gas filed a
prospectus with the Securities and Exchange Commission with respect to the
issuance of $70 million in debt securities. On December 28, 2000, $20 million of
15-Year Insured Quarterly (IQ) Notes bearing interest at a rate of 7.15 percent
per year and $50 million of 30-Year IQ Notes bearing interest at a rate of 7.45
percent per year were issued. The 15-Year IQ Notes will mature on December 15,
2015, and the 30-Year IQ Notes will mature on December 16, 2030, unless, in each
case, redeemed prior to that date. Indiana Gas will have the option to redeem
the 15-Year IQ Notes, in whole or in part, from time to time on or after
December 15, 2004. Indiana Gas will have the option to redeem the 30-Year IQ
Notes in whole or in part, from time to time on or after December 15, 2005. The
net proceeds of the debt issuance were used to repay outstanding commercial
paper utilized for general corporate purposes.

10.   Fair Value of Financial Instruments

The carrying values and estimated fair values of Vectren's financial instruments
were as follows:

                                                   At December 31,

                                    --------   ----------  --------  -----------
Short-term borrowings               $759,908   $ 759, 908  $207,638   $207,638
Partnership obligations (includes
    amounts due within one year          249          312       845        905
Redeemable preferred stock of
    subsidiary                         7,500        7,737     7,500      7,538
Long term debt (includes
    amounts due within one year)     685,903      758,478   541,202    544,928



 38

Certain methods and assumptions must be used to estimate the fair value of
financial instruments. Because of the short maturity of notes payable, the
carrying amounts approximate fair values for these financial instruments. The
fair value of Vectren's long-term debt was estimated based on the quoted market
prices for the same or similar issues or on the current rates offered to Vectren
for debt of the same remaining maturities. The fair value of partnership
obligations was estimated based on current quoted market rate of comparable
debt. The fair value of redeemable preferred stock of SIGECO was based on the
current quoted market rate of long-term debt with similar characteristics.

Under current regulatory treatment, call premiums on reacquisition of long-term
debt are generally recovered in customer rates over the life of the refunding
issue or over a 15-year period (see Note 5M ). Accordingly, any reacquisition
would not be expected to have a material effect on Vectren's financial position
or results of operations.

The market price used to value these transactions reflects management's best
estimate of market prices considering various factors, including published
prices for certain delivery locations, time value and volatility factors
underlying the commitments.

11.   Common Stock

On March 31, 2000, the merger of Indiana Energy and SIGCORP with and into
Vectren was consummated with a tax-free exchange of shares and has been
accounted for as a pooling of interests. The common shareholders of SIGCORP
received 1.333 shares of Vectren common stock for each SIGCORP common share and
the common shareholders of Indiana Energy received one share of Vectren common
stock for each Indiana Energy common share, resulting in the issuance of 61.3
million shares of Vectren common stock.

The Vectren board of directors has adopted a Shareholder Rights Agreement. Under
the Shareholder Rights Agreement, the Vectren board of directors has declared a
dividend distribution of one right for each outstanding Vectren common share. A
right will attach to each Vectren common share Vectren issues. Each right
entitles the holder to purchase from Vectren one share at a price of $65.00 per
share (subject to adjustment to prevent dilution). Initially, the rights will
not be exercisable. The rights only become exercisable 10 days following a
public announcement that a person or group of affiliated or associated persons
(Vectren Acquiring Person) has acquired beneficial ownership of 15 percent or
more of the outstanding Vectren common shares (or a 10 percent acquirer who is
determined by the Vectren board of directors to be an adverse person), or 10
days following the announcement of an intention to make a tender offer or
exchange offer the consummation of which would result in any person or group
becoming a Vectren Acquiring Person. The Vectren Shareholder Rights Agreement
expires October 21, 2009.

Conversion of Options

Certain SIGCORP and SIGECO employees held options to purchase SIGCORP common
shares granted under the 1994 SIGECO Stock Option Plan and other employee
compensation benefits arrangements. When the merger was consummated, each
unexpired and unexercised option to purchase SIGCORP common shares was
automatically converted into an option to purchase the number of Vectren common
shares that could have been purchased under the original option multiplied by
1.333. The exercise price per Vectren common share under the new option is equal
to the original per share price divided by 1.333. The new Vectren options will
otherwise be subject to the same terms and conditions as the original SIGCORP
options. The expiration dates for options outstanding as of December 31, 2000,
ranged from July 13, 2004 to July 19, 2009. This stock option activity for the
past three years, converted to Vectren common shares, was as follows:

Vectren accounts for stock compensation in accordance with APB 25, "Accounting
for Stock Issued to Employees." Under APB 25, no compensation cost has been
recognized for stock options. Had compensation cost for stock options been
determined consistent with SFAS No. 123 "Accounting for Stock-based
Compensation," net income would have been reduced to the following pro forma
amounts:

The fair value of each option granted used to determine pro forma net income is
estimated as of the date of grant using the Black-Scholes option pricing model
with the following weighted average assumptions used for grants in the years
ended December 31, 1999 and 1998: risk-free interest rate of 6.46 percent and
4.44 percent, respectively; expected option term of five years; expected
volatilities of 34.00 percent and 33.16 percent, respectively; and dividend
rates of 4.46 percent and 3.77 percent, respectively. The weighted average fair
value of options granted in 1999 and 1998 were $5.05 and $5.99, respectively. No
options were granted in 2000.

Conversion of Restricted Stock

Indiana Energy had an Executive Restricted Stock Plan for the principal officers
of the company and participating subsidiary companies. Indiana Energy also had a
Directors' Restricted Stock Plan through which non-employee directors receive
one-third of their combined compensation (exclusive of attendance fees) as
directors of Indiana Energy, Indiana Gas or IEI Investments, Inc. in shares of
Indiana Energy's common stock subject to certain restrictions on
transferability.

Upon consummation of the merger, the restrictions on each outstanding share of
restricted stock of Indiana Energy lapsed and all shares of Indiana Energy that
were issued as restricted stock were treated as unrestricted shares of Indiana
Energy in the merger exchange. During 2000, Vectren adopted these plans and
194,884 restricted shares were issued to executives and non-employee directors.
Shares of restricted stock issued in 1999 and 1998 by Indiana Energy were 15,238
and 14,303, respectively.

The cost of these performance based awards, determined to be the fair market
value at the date of grant, is charged to compensation expense as earned over
the performance periods. The weighted average fair value of these stock based
instruments, together with recognized compensation expense, was $2.3 million and
$19.90 in 2000; $0.8 million and $23.20 in 1999; and $0.7 million and $20.26 in
1998. Substantially all of the year 2000 expense is for the lifting of
restrictions triggered by the merger transaction.

Common stock dividends of Vectren may be reinvested under a Dividend
Reinvestment and Stock Purchase Plan. Common shares purchased in connection with
the plan are currently being acquired through the open market.

At December 31, 2000 and 1999, respectively, shares of common stock reserved for
issuance were as follows:

12.   Earnings Per Share

Basic earnings per share is computed by dividing net income available to common
shareholders by the weighted-average number of common shares outstanding for the
period. Diluted earnings per share assumes the conversion of stock options into
common shares using the treasury stock method to the extent the effect would be
dilutive.

The following table illustrates the basic and dilutive earnings per share
calculations.




                                                                Year Ended December 31,

Options to purchase 526,469 common shares for the year ended December 31, 2000
and 99,973 common shares for the years ended December 31, 1999 and 1998 were not
included in the computation of dilutive earnings per share because the options'
exercise prices were greater than the average market price of the common shares
during the period. Exercise prices for options excluded from the computation
ranged from $19.83 to $24.05 in 2000 and equaled $24.05 in 1999 and 1998.

Subsequent to December 31, 2000, Vectren issued about 6.3 million common shares
in a public offering (see Note 22).

13.   Retirement Plans and Other Postretirement Benefits

Prior to July 1, 2000, SIGCORP and Indiana Energy had separate retirement and
other postretirement benefit plans. The activities in these plans are described
below by company. Effective July 1, 2000, the SIGECO and Indiana Energy pension
plans for employees not covered by a collective bargaining unit were merged.
Also effective July 1, 2000, the SIGECO and Indiana Energy retirement savings
plans for employees not covered by a collective bargaining unit were merged, as
were their postretirement health care and life insurance plans.

Vectren has multiple defined benefit pension and other postretirement benefit
plans which cover eligible full-time regular employees. All of the plans are
non-contributory with the exception of the health care plan which contains
cost-sharing provisions whereby employees retiring after January 1, 1996, are
required to make contributions to the plan when increases in Indiana Energy's
health care costs exceed the general rate of inflation, as measured by the
Consumer Price Index (CPI). The nonpension plans include plans for health care
and life insurance through a combination of self-insured and fully insured
plans.

The IURC has authorized SIGECO and Indiana Gas to recover the costs related to
postretirement benefits other than pensions under the accrual method of
accounting consistent with Statement of Financial Accounting Standards No. 106,
Employers' Accounting for Postretirement Benefits Other Than Pensions. Amounts
accrued prior to that authorization were deferred as allowed by the IURC and
amortized over a 60-month period.

The detailed disclosures of benefit components that follow are based on an
actuarial valuation performed for the December 31, 2000 financial statements
using a measurement date as of September 30, 2000. The disclosures required as
of and for the years ended December 31, 1999 and 1998 have been restated based
on actuarial valuations previously performed for SIGECO as of December 31 and
Indiana Gas as of September 30, respectively. In management's opinion,
disclosures from revised actuarial valuations would not differ materially from
those presented below.

The aggregate benefit obligation and aggregate fair value of the plan assets for
pension plans with benefit obligations in excess of plan assets were $10.5
million and $7.9 million, respectively, as of December 31, 2000, and $5.5
million and $4.5 million, respectively, as of December 31, 1999.

Weighted-average assumptions used in the accounting for these plans were as
follows:

                                               Year Ended December 31,
                                               ----------------------

As of December 31, 2000, the health care cost trend is 7 percent declining to 5
percent in 2004 and remaining level thereafter. The accrued health care cost
trend rate for 2001 is 7 percent. The estimated cost of these future benefits
could be significantly affected by future changes in health care costs, work
force demographics, interest rates or plan changes.

A 1 percent change in the assumed health care cost trend for Vectren's
postretirement health care plan would have the following effects:

Vectren has adopted Voluntary Employee Beneficiary Association (VEBA) Trust
Agreements for the funding of postretirement health benefits for retirees and
their eligible dependents and beneficiaries. Annual funding is discretionary and
is based on the projected cost over time of benefits to be provided to cover
persons consistent with acceptable actuarial methods. To the extent these
postretirement benefits are funded, the benefits will not be shown as a
liability on Vectren's financial statements.

Vectren also has defined contribution retirement savings plans that are
qualified under sections 401(a) and 401(k) of the Internal Revenue Code. During
2000, 1999, and 1998, Vectren made contributions to these plans of $1.6 million,
$1.9 million and $2.3 million, respectively.

14.   Leveraged Leases

Southern Indiana Properties, Inc. (SIPI), a wholly owned subsidiary, is a lessor
in several leveraged lease agreements under which real estate or equipment is
leased to third parties. The economic lives and lease terms vary with the
leases. The total equipment and facilities cost was approximately $409.7 million
at December 31, 2000 and 1999. The cost of the equipment and facilities was
partially financed by nonrecourse debt provided by lenders, who have been
granted an assignment of rentals due under the leases and a security interest in
the leased property, which they accepted as their sole remedy in the event of
default by the lessee. Such debt amounted to approximately $380.0 million and
$373.5 million at December 31, 2000 and 1999, respectively. SIPI's net
investment in leveraged leases at December 31, 2000 and 1999, respectively, was
as follows:

15.   Commitments and Contingencies

Future minimum lease payments required under operating leases that have initial
or remaining noncancellable lease terms in excess of one year as of December 31,
2000 are as follows:

          Total                           $23.6
                                      ============

Total lease expense, in millions, was $3.4 in 2000, $2.7 in 1999, and $2.2 in
1998.

As part of a restructuring plan initiated by Indiana Energy in 1997, a charge
was recorded to reflect the corporate office facility at fair value. The company
then entered into a sale leaseback transaction with a third party which was
completed in 1998, resulting in proceeds of $9.2 million and an operating lease
with a 10 year term with rental payments of $1.5 million per year. The annual
payments are included in the future minimum lease payments above.

Vectren is party to various legal proceedings arising in the normal course of
business. In the opinion of management, with the exception of litigation matters
related to the Clean Air Act and ProLiance, there are no legal proceedings
pending against Vectren that are likely to have a material adverse effect on the
financial position or results of operations. Refer to Note 6 for litigation
matters related to ProLiance and Note 17 for litigation matters concerning the
Clean Air Act.

A wholly owned subsidiary of Vectren has an 8.3 percent ownership interest in
Pace Carbon Synfuels Investors, LP (Pace Carbon), a Delaware limited partnership
formed to develop, own and operate four projects to produce and sell coal-based
synthetic fuel. In addition to its initial investment of $7.5 million, Vectren
has a continuing obligation to invest approximately $40 million in Pace Carbon,
with any such additional investments to be funded to the extent it generates
federal tax credits that are earned from the production and sale of briquettes
by the projects. As of December 31, 2000 and 1999, Vectren's net investment in
Pace Carbon, which is accounted for using the equity method of accounting,
totaled approximately $6.7 million and $6.3 million, respectively, and is
included in investments in partnerships and other corporations in the
Consolidated Balance Sheets.

A wholly owned subsidiary of Vectren has an approximate 40 percent ownership
interest in Haddington Energy Partners, LP (Haddington) and has committed to
invest $10 million of which $9.8 million has been funded as of December 31,
2000. Haddington, a Delaware limited partnership, raised $77 million to invest
in energy projects. On July 28, 2000, Vectren made a commitment to fund an
additional $20 million in Haddington Energy Partners II, LP, which is expected
to raise an additional $150 million. This second fund will provide additional


 45

capital for the initial fund portfolio companies as well as make investments in
new areas, such as distributed generation, power backup and quality devices, and
emerging technologies such as fuel cells, microturbines and photovoltaics.
Through December 31, 2000, Vectren had invested approximately $2.1 million of
this $20 million commitment to Haddington II. Upon complete funding, Vectren
will have an approximate 40 percent ownership interest in Haddington II. The
remainder of this investment is expected to be made through 2002. As of December
31, 2000 and 1999, Vectren's net investment in the Haddington Ventures, both of
which are accounted for using the equity method of accounting, totaled
approximately $13.0 million and $2.6 million, respectively, and is included in
investments in partnerships and other corporations in the Consolidated Balance
Sheets.

Vectren has entered into a contract to purchase and construct an 80-megawatt
combustion gas turbine generator which will be owned by SIGECO. The total
capital cost of the project is estimated to be $33 million during the 2001-2002
construction period.

Vectren has invested to date approximately $33 million with Utilicom Networks.
On December 22, 2000, Vectren announced its commitment to invest up to $100
million with Utilicom Networks, pending completion of all funding (see Note 7).

Indiana Gas, SIGECO and the Ohio operations use a normalized method of
accounting for deferred income taxes as required by the IURC and PUCO. Deferred
income taxes reflect the net tax effect of temporary differences between the
carrying amounts of assets and liabilities for financial reporting purposes and
the amounts used for income tax purposes. Deferred income taxes are provided for
taxes not currently payable due to, among other things, the use of various
accelerated depreciation methods, shorter depreciable lives and the deduction of
certain construction costs for tax purposes. Taxes deferred in prior years are
being charged and income credited as these tax effects reverse over the lives of
the related assets.

Significant components of Vectren's net deferred tax liability as of December
31, 2000 and 1999 are as follows:

At December 31, 2000, the components of the net deferred tax liability are
reflected in the Consolidated Balance Sheets as a long-term liability of
approximately $229.9 million and as a reduction to accrued taxes in current
liabilities of approximately $17.1 million.

Investment tax credits have been deferred and are being credited to income over
the life of the property, giving rise to the credit. The Tax Reform Act of 1986
eliminated investment tax credits for property acquired after January 1, 1986.

At December 31, 2000, Vectren has Alternative Minimum Tax credit carryforward of
approximately $13 million, which has no expiration date. Through certain of its
non-regulated subsidiaries and investments, Vectren also realizes Federal income
tax credits associated with affordable housing projects, historical
rehabilitation projects and projects for the production and sale of synthetic
fuels. At December 31, 2000, Vectren has tax credit carryforwards of
approximately $4.1 million which expire in 20 years.

17.  Environmental Matters

Clean Air Act

NOx SIP Call Matter. In October 1997, the United States Environmental Protection
Agency (USEPA) proposed a rulemaking that could require uniform nitrogen oxide
(NOx) emissions reductions of 85 percent by utilities and other large sources in
a 22-state region spanning areas in the Northeast, Midwest, Great Lakes,
Mid-Atlantic and South. This rule is referred to as the "NOx SIP call". The
USEPA provided each state a proposed budget of allowed NOx emissions, a key
ingredient of ozone, which requires a significant reduction of such emissions.
Under that budget, utilities may be required to reduce NOx emissions to a rate
of 0.15 lb/mmBtu below levels already imposed by Phase I and Phase II of the
Clean Air Act Amendments of 1990 (the Act). Midwestern states (the alliance)
have been working together to determine the most appropriate compliance strategy
as an alternative to the USEPA proposal. The alliance submitted its proposal,
which calls for a smaller, phased in reduction of NOx levels, to the USEPA and
the Indiana Department of Environmental Management (IDEM) in June 1998.

In July 1998, Indiana submitted its proposed plan to the USEPA in response to
the USEPA's proposed new NOx rule and the emissions budget proposed for Indiana.
The Indiana plan, which calls for a reduction of NOx emissions to a rate of 0.25
lb/mmBtu by 2003, is less stringent than the USEPA proposal but more stringent
than the alliance proposal.

On October 27, 1998, USEPA issued a final rule "Finding of Significant
Contribution and Rulemaking for Certain States in the Ozone Transport Assessment
Group Region for Purposes of Reducing Regional Transport of Ozone," (63 Fed.
Reg. 57355). The final rule requires that 23 states and jurisdictions must file


 47

revised state implementation plans (SIPs) with the USEPA by no later than
September 30, 1999, which was essentially unchanged from its October 1997,
proposed rule. The USEPA has encouraged states to target utility coal-fired
boilers for the majority of the reductions required, especially NOx emissions.
Northeastern states have claimed that ozone transport from midwestern states
(including Indiana) is the primary reason for their ozone concentration
problems. Although this premise is challenged by others based on various air
quality modeling studies, including studies commissioned by the USEPA, the USEPA
intends to incorporate a regional control strategy to reduce ozone transport.
The USEPA's final ruling is being litigated in the federal courts by
approximately ten midwestern states, including Indiana.

During the second quarter of 1999, the USEPA lost two federal court challenges
to key air-pollution control requirements. In the first ruling by the U.S.
Circuit Court of Appeals for the District of Columbia on May 14, 1999, the Court
struck down the USEPA's attempt to tighten the one-hour ozone standard to an
eight-hour standard and the attempt to tighten the standard for particulate
emissions, finding the actions unconstitutional. In the second ruling by the
same Court on May 25, 1999, the Court placed an indefinite stay on the USEPA's
attempts to reduce the allowed NOx emissions rate from levels required by the
Clean Air Act Amendments of 1990. The USEPA appealed both court rulings. On
October 29, 1999, the Court refused to reconsider its May 14, 1999 ruling.

On March 3, 2000, the D.C. Circuit of Appeals upheld the USEPA's October 27,
1998 final rule requiring 23 states and the District of Columbia to file revised
SIPs with the USEPA by no later than September 30, 1999. Numerous petitioners,
including several states, have filed petitions for rehearing with the U.S. Court
of Appeals for the District of Columbia in Michigan v. the USEPA. On June 22,
2000, the D.C. Circuit Court of Appeals denied petition for rehearing en banc
and lifted its May 25, 1999 stay. Following this decision, on August 30, 2000,
the D.C. Circuit Court of Appeals issued an extension of the SIP Call
implementation deadline, previously May 1, 2003, to May 31, 2004. On September
20, 2000, petitioners filed a Petition of Writ of Certiori with the United
States Supreme Court requesting review of the D.C. Circuit Court's March 3, 2000
Order. The Court has not yet ruled on the Petition for Certiorari. The EPA
granted Section 126 Petitions filed by northeastern states that require named
sources in the eastern half of Indiana to achieve NOx reduction by May 1, 2003.
No SIGECO facilities are named in the Section 126 Petitions filed by
northeastern states, therefore the compliance date remains May 31, 2004.

The proposed NOx emissions budget for Indiana stipulated in the USEPA's final
ruling requires a 36 percent reduction in total NOx emissions from Indiana. The
ruling, pending finalization of state rule making, could require SIGECO to lower
its system-wide emissions by approximately 70 percent. Depending on the level of
system-wide emissions reductions ultimately required, and the control technology
utilized to achieve the reductions, the estimated construction costs of the
control equipment could reach $160 million, which are expected to be expended
during the 2001-2004 period, and related additional operation and maintenance
expenses could be an estimated $8 million to $10 million, annually. No accrual
has been recorded by the company related to the NOx SIP Call matter. The rules
governing NOx emissions, once finalized, are to be applied prospectively.


Mercury Emissions. On December 14, 2000, the USEPA released a statement
announcing that reductions of mercury emissions from coal-fired plants will be
required in the near future. The USEPA will propose regulations by December 2003
and issue final rules by December 2004.

Under the Act, the USEPA is required to study emissions from power plants in
order to determine if additional regulations are necessary to protect public
health. The USEPA reported its study to Congress in February 1998. That study
concluded that of all toxic pollution examined, mercury posed the greatest
concern to public health. An earlier USEPA study concluded that the largest
source of human-made mercury pollution in the United States was coal-fired power
plants.

After completion of the study, the Act required the USEPA to determine whether
to proceed with the development of regulations. The USEPA announced that it had
affirmatively decided that mercury air emissions from power plants should be
regulated. Because rules governing mercury emissions are under development, the


 48

determination of exposure, if any, is impossible as there are no standards or
rules by which compliance (or lack thereof) can be measured. Accordingly, no
accrual has been recorded by the company related to the mercury emissions
matter.


Culley Generating Station Investigation Matter. The USEPA initiated an
investigation under Section 114 of the Act of SIGECO's coal-fired electric
generating units in commercial operation by 1977 to determine compliance with
environmental permitting requirements related to repairs, maintenance,
modifications and operations changes. The focus of the investigation was to
determine whether new source performance standards should be applied to the
modifications and whether the best available control technology was, or should
have been, used. Numerous other electric utilities were, and are currently,
being investigated by the USEPA under an industry-wide review for similar
compliance. SIGECO responded to all of the USEPA's data requests during the
investigation. In July 1999, SIGECO received a letter from the Office of
Enforcement and Compliance Assurance of the USEPA discussing the industry-wide
investigation, vaguely referring to the investigation of SIGECO and inviting
SIGECO to participate in a discussion of the issues. No specifics were noted;
furthermore, the letter stated that the communication was not intended to serve
as a notice of violation. Subsequent meetings were conducted in September and
October with the USEPA and targeted utilities, including SIGECO, regarding
potential remedies to the USEPA's general allegations.

On November 3, 1999, the USEPA filed a lawsuit against seven utilities,
including SIGECO. The USEPA alleges that, beginning in 1992, SIGECO violated the
Act by: (i) making modifications to its Culley Generating Station in Yankeetown,
Indiana without obtaining required permits; (ii) making major modifications to
the Culley Generating Station without installing the best available emission
control technology; and (iii) failing to notify the USEPA of the modifications.
In addition, the lawsuit alleges that the modifications to the Culley Generating
Station required SIGECO to begin to comply with federal new source performance
standards.

SIGECO believes it performed only maintenance, repair and replacement activities
at the Culley Generating Station, as allowed under the Act. Because proper
maintenance does not require permits, application of the best available emission
control technology, notice to the USEPA, or compliance with new source
performance standards, SIGECO believes that the lawsuit is without merit, and
intends to vigorously defend the lawsuit.

The lawsuit seeks fines against SIGECO in the amount of $27,500 per day per
violation. The lawsuit does not specify the number of days or violations the
USEPA believes occurred. The lawsuit also seeks a court order requiring SIGECO
to install the best available emissions technology at the Culley Generating
Station. If the USEPA is successful in obtaining an order, SIGECO estimates that
it would incur capital costs of approximately $40 million to $50 million
complying with the order. In the event that SIGECO is required to install
system-wide NOx emission control equipment, as a result of the NOx SIP call
issue, the majority of the $40 million to $50 million for best available
emissions technology at Culley Generating Station would be included in the $160
million expenditure previously discussed.

The USEPA has also issued an administrative notice of violation to SIGECO making
the same allegations, but alleging that violations began in 1977.

While it is possible that SIGECO could be subjected to criminal penalties if the
Culley Generating Station continues to operate without complying with the new
source performance standards and the allegations are determined by a court to be
valid, SIGECO believes such penalties are unlikely as the USEPA and the electric
utility industry have a bonafide dispute over the proper interpretation of the
Act. Accordingly, no accrual has been recorded by the company, and SIGECO
anticipates at this time that the plant will continue to operate while the
matter is being decided.

Information Request. On January 23, 2001, SIGECO received an information request
from the USEPA under Section 114(a) of the Act for historical operational
information on the Warrick and A.B. Brown generating stations. SIGECO plans to
provide all information requested, and management believes that no significant
issues will arise from this request.

Manufactured Gas Plants

In the past, Indiana Gas and others operated facilities for the manufacture of
gas. Given the availability of natural gas transported by pipelines, these
facilities have not been operated for many years. Under currently applicable
environmental laws and regulations, Indiana Gas and the others may now be
required to take remedial action if certain byproducts are found above the
regulatory thresholds at these sites.

Indiana Gas has identified the existence, location and certain general
characteristics of 26 gas manufacturing and storage sites for which it may have
some remedial responsibility. Indiana Gas has completed a remedial
investigation/feasibility study (RI/FS) at one of the sites under an agreed
order between Indiana Gas and IDEM, and a Record of Decision was issued by IDEM
in January 2000. Although Indiana Gas has not begun an RI/FS at additional
sites, Indiana Gas has submitted several of the sites to IDEM's Voluntary
Remediation Program (VRP) and is currently conducting some level of remedial
activities including groundwater monitoring at certain sites where deemed
appropriate and will continue remedial activities at the sites as appropriate
and necessary.

In conjunction with data compiled by expert consultants, Indiana Gas has accrued
the estimated costs for further investigation, remediation, groundwater
monitoring and related costs for the sites. While the total costs that may be
incurred in connection with addressing these sites cannot be determined at this
time, Indiana Gas has accrued costs that it reasonably expects to incur totaling
approximately $20.3 million.

The estimated accrued costs are limited to Indiana Gas' proportionate share of
the remediation efforts. Indiana Gas has arrangements in place for 19 of the 26
sites with other potentially responsible parties, which serve to limit Indiana
Gas' share of response costs at these 19 sites to between 20 and 50 percent.

With respect to insurance coverage, as of December 31, 2000, Indiana Gas has
received and recorded settlements from all known insurance carriers in an
aggregate amount approximating its $20.3 million accrual.

Environmental matters related to manufactured gas plants have had no material
impact on earnings since costs recorded to date approximate PRP and insurance
settlement recoveries. While Indiana Gas has recorded all costs which it
presently expects to incur in connection with activities at these sites, it is
possible that future events may require some level of additional remedial
activities which are not presently foreseen.

18.  Rate and Regulatory Matters

As a result of the ongoing appeal of a generic order issued by the IURC in
August 1999 regarding guidelines for the recovery of purchased power costs,
SIGECO entered into a settlement agreement with the Indiana Office of Utility
consumer Counselor (OUCC) that provides certain terms with respect to the
recoverability of such costs. The settlement, originally approved by the IURC on
August 9, 2000, has been extended by agreement through March 2002. Under the
settlement, SIGECO can recover the entire cost of purchased power up to an
established benchmark, and during forced outages, SIGECO will bear a limited
share of its purchased power costs regardless of the market costs at that time.
Based on this agreement, SIGECO believes it has significantly limited its
exposure to unrecoverable purchased power costs.

Commodity prices for natural gas purchases during the last six months of 2000
increased significantly, primarily due to the expectation of a colder winter,
which led to increased demand and tighter supplies. Vectren's utility
subsidiaries are typically allowed full recovery of such charges in purchased
gas costs from their retail customers through commission-approved gas cost
adjustment (GCA). On October 11, 2000, Indiana Gas filed for approval of its
quarterly GCA. In early December, the IURC issued an interim order approving the
request by Indiana Gas for a GCA factor for December 2000. On January 4, 2001,
the IURC approved the January and February 2001 GCA as filed. The order also
addressed the claim by the 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


 50

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 IURC found that there should be a $3.8 million disallowance related to
gas procurement for the winter season. As a result, Indiana Gas recognized a
pre-tax charge of $3.8 million in December 2000. Both Indiana Gas and the OUCC
have appealed this ruling. The Citizens Action Coalition of Indiana, Inc., a not
for profit consumer advocate, has also filed with the IURC a petition to
intervene and a notice of appeal of the order.

19.   Affiliate Transactions

ProLiance provides natural gas supply and related services to Indiana Gas.
Indiana Gas' purchases from ProLiance for resale and for injections into storage
for the years ended December 31, 2000 and 1999, totaled $401.4 million and
$240.7 million, respectively. As of December 31, 2000 and 1999, Vectren's net
investment in ProLiance, which is accounted for using the equity method of
accounting, totaled approximately $27.8 million and $16.2 million, respectively,
and is included in investments in partnerships and other corporations in the
Consolidated Balance Sheets.

ProLiance has a standby letter of credit facility with a bank for letters up to
$45.0 million. This facility is secured in part by a support agreement from
Vectren. Letters of credit outstanding at December 31, 2000 totaled $22.0
million.

CIGMA, LLC (CIGMA), owned jointly and equally by a wholly owned subsidiary of
Vectren and a third party, provides materials acquisition and related services
that are used by Indiana Gas and others. Indiana Gas' purchases of these
services during the years ended December 31, 2000 and 1999, totaled $17.2
million and $17.3 million, respectively. As of December 31, 2000 and 1999,
Vectren's net investment in CIGMA, which is accounted for using the equity
method of accounting, totaled approximately $4.2 million and is included in
investments in partnerships and other corporations in the Consolidated Balance
Sheets.

Reliant Services, LLC (Reliant), owned jointly and equally by a wholly owned
subsidiary of Vectren and Cinergy Corp., provides utility locating, meter
reading and construction services to Indiana Gas and others. Amounts paid by
Indiana Gas to Reliant for such services totaled $3.7 million and $2.9 million
for years ended December 31, 2000 and 1999, respectively. On December 13, 2000,
Reliant purchased the common stock of Miller Pipeline Corporation from NiSource,
Inc. for approximately $68.3 million. Vectren and Cinergy Corp. each contributed
$16 million of equity, and the remaining $36.3 million was funded with 7-year
intermediate bank loans. As of December 31, 2000 and 1999, Vectren's net
investment in Reliant, which is accounted for using the equity method of
accounting, totaled approximately $19.2 million and $3.6 million, respectively,
and is included in investments in partnerships and other corporations in the
Consolidated Balance Sheets.

Vectren is a two-thirds guarantor of certain surety bond and other obligations
of Energy Systems Group, LLC, a two-thirds owned consolidated subsidiary.
Vectren's share of the guarantee of such obligations totaled $50.6 million at
December 31, 2000.

Amounts owed to unconsolidated affiliates totaled $102.5 million and $29.3
million at December 31, 2000 and 1999, respectively, and are included in
accounts payable to affiliated companies on the Consolidated Balance Sheets. The
$73.2 million increase at December 31, 2000 is due primarily to amounts owed to
ProLiance resulting from the much higher gas prices and increased customer
consumption. Amounts due from unconsolidated affiliates totaled $17.6 million
and $7.6 million at December 31, 2000 and 1999, respectively, and are included
in accounts receivable on the Consolidated Balance Sheets.

20.   Segment Reporting

SFAS 131 "Disclosure about Segments of an Enterprise and Related Information"
establishes standards for the reporting of information about operating segments
in financial statements and disclosures about products, services and
geographical areas. Operating segments are defined as components of an
enterprise for which separate financial information is available and evaluated
regularly by the chief operating decision makers in deciding how to allocate
resources and in the assessment of performance.

There were three operating segments of Vectren during 2000: (1) Gas Utility
Services, (2) Electric Utility Services, and (3) Non-regulated Operations. The
Gas Utility Services segment includes regulated gas utilities which provide
natural gas distribution and transportation services. The Electric Utility
Services segment generates, transmits and distributes and sells electricity
within primarily southwestern Indiana communities. The Non-regulated Operations
segment is made up of various businesses providing energy-related products and
services; telecommunication products and services; materials management, debt
collection and meter reading services; underground utility asset location and
construction services; structured finance and investment transactions including
leveraged leases of real estate and equipment; venture capital projects; coal
mining and sales; and other energy-related services. Revenues for each segment
are principally attributable to customers in the United States.

The following tables provide information about business segments. Vectren makes
decisions on finance and dividends at the corporate level; these topics are
addressed on a consolidated basis. In addition, adjustments have been made to
the segment information to arrive at information included in the consolidated
results of operations and financial position. These adjustments include
unallocated corporate assets, revenues and expenses and the elimination of
intercompany transactions.

              MANAGEMENT'S RESPONSIBILITY FOR FINANCIAL STATEMENTS

The management of Vectren Corporation is responsible for the preparation of the

this report. The financial statements are prepared in conformity with accounting
principles generally accepted in the United States and follow accounting
policies and principles applicable to regulated public utilities.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders and Board of Directors of Vectren Corporation:

We have audited the accompanying consolidated balance sheets of Vectren
Corporation (an Indiana corporation) and subsidiary companies as of December 31,
2000 and 1999, and the related consolidated statements of income, common
shareholders' equity and cash flows for each of the three years in the period
ended December 31, 2000. These financial statements are the responsibility of
the company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Vectren Corporation
and subsidiary companies as of December 31, 2000 and 1999, and the results of
their operations and their cash flows for each of the three years in the period
ended December 31, 2000, in conformity with accounting principles generally
accepted in the United States.
