ITEM 1.   BUSINESS

Indiana Gas Company, Inc. (Indiana Gas) is an operating public
utility incorporated July 16,1945 under laws of the state of
Indiana and is a wholly owned subsidiary of Vectren Corporation
(Vectren).  Indiana Gas provides transportation, distribution and
sale of natural gas to a diversified base of customers in 311
communities in 49 of Indiana's 92 counties.

Vectren was organized on June 10, 1999 solely for the purpose of
effecting the merger of Indiana Energy, Inc. (Indiana Energy),
Indiana Gas' former parent company, 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
that has been accounted for as a pooling-of-interests. Prior to
March 31, 2000, all of the outstanding shares of common stock of
Indiana Gas were owned by Indiana Energy.   Vectren has a
December 31 fiscal year end. In order to report Indiana Gas'
financial operations on a consistent basis with Vectren
Corporation, Indiana Gas changed its year end from September 30
to December 31.  The merger did not affect Indiana Gas' debt
securities.

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 the company 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,
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."  Vectren
Utility Holdings, Inc. (VUHI), Vectren's intermediate holding
company for its operating public utilities, including Indiana
Gas, established a $435 million commercial paper program to fund
the majority of the acquisition.  Indiana Gas' investment in the
Ohio operations of approximately $218 million was funded with a
combination of short-term borrowings from VUHI and Indiana Gas'
commercial paper program.

Overview

During 2000, Indiana Gas supplied gas to  524,427 customers,
including 476,073 residential, 47,359 commercial and 995 contract
in 311 communities in 49 of the 92 counties in the state of
Indiana.

The service area has a population of approximately 2 million and
contains diversified manufacturing and agriculture-related
enterprises.  The principal industries served include automotive
parts and accessories, feed, flour and grain processing, metal
castings, aluminum products, gypsum products, electrical
equipment, metal specialties and glass.

The largest communities served include Muncie, Anderson,
Lafayette-West Lafayette, Bloomington, Terre Haute, Marion, New
Albany, Columbus, Jeffersonville, New Castle and Richmond.

Revenues

For the year ended December 31, 2000, revenues were approximately
$598.1 million of which residential customers provided 65
percent, small commercial 24 percent and contract 11 percent.
During the year ended December 31, 2000, Indiana Gas added
approximately 11,000 residential and commercial customers.

Indiana Gas receives gas revenues by selling gas directly to
residential and commercial customers at approved rates or by
transporting gas through its pipelines at approved rates to
contract customers that have purchased gas directly from other
producers, brokers or marketers.  Total volume of gas provided to
both sales and transportation customers (throughput) was 126,960
MDth for the year ended December 31, 2000.  Transported gas
represented 49 percent of total throughput. Rates for
transporting gas provide for the same margins generally earned by
selling gas under applicable sales tariffs.

The sale of gas is seasonal and strongly affected by variations
in weather conditions.  To mitigate seasonal demand, Indiana Gas
owns and operates five underground gas storage fields, four
liquefied petroleum (propane) air-gas manufacturing plants and
maintains contract storage.  Natural gas purchased from suppliers
is injected into storage during periods of light demand which are
typically periods of lower prices.  The injected gas is then
available to supplement contracted volumes during periods of peak
requirements. Approximately 169,000 Dth of gas per day can be
withdrawn from storage during peak demand periods.

Gas Purchases

Effective April 1, 1996, Indiana Gas purchases all of its natural
gas and winter delivery service from ProLiance Energy, LLC
(ProLiance).  ProLiance is a 50 percent owned non-regulated
energy marketing affiliate of Vectren.   Indiana Gas purchased
68,230 MDth volumes of gas at an average cost of $5.77 per MDth.
(See Note 14 in Indiana Gas' financial statements included in
Item 8 Financial Statements and Supplementary Data regarding
transactions with ProLiance).

Regulatory Matters

Indiana Gas' rates and charges, terms of service, accounting
matters, issuance of securities, and certain other operational
matters are regulated by the Indiana Utility Regulatory
Commission (IURC).

Adjustments to rates and charges related to the cost of gas
charged are made through gas cost adjustment (GCA) procedures
established by Indiana law and administered by the IURC. GCA
procedures involve scheduled quarterly filings and IURC hearings
to establish the amount of price adjustments for a designated
future quarter. The procedures also provide for inclusion in
later quarters of any variances between estimated and actual
costs of gas sold in a given quarter.   This reconciliation
process with regard to changes in the cost of gas sold closely
matches revenues to expenses.  The IURC has also applied the
statute authorizing the GCA procedures to reduce rates when
necessary so as to limit net operating income to the level
authorized in its last general rate order.  An earnings test
operates in conjunction with GCA procedures. Recovery of gas
costs is not allowed to the extent that total operating income
for a 60-month period, including the twelve-month period provided
in the gas cost adjustment filing, exceeds the total operating
income authorized by the IURC.  For the period 1998 through 2000,
the earnings test has not affected the company's ability to
recover gas costs, and the company does not anticipate the
earnings test will restrict the recovery of gas costs in the near
future. (See the Rate and Regulatory Matters section of
Management's Discussion and Analysis of Financial Condition and
Results of Operations in Item 7 regarding a $3.8 million
disallowance of gas costs.)

<PAGE> 4

Indiana Gas' rate structures does not include a weather
normalization-type clause whereby it would be authorized to
recover the gross margin on sales established in its last general
rate case, regardless of actual weather patterns.


Environmental Matters

See Note 12 of Indiana Gas' financial statements in Item 8
Financial Statements and Supplementary Data regarding
manufactured gas plants.

Competition

The utility industry has been undergoing dramatic structural
change for several years, resulting in increasing competitive
pressures faced by 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.  Ohio regulation provides for choice of
commodity for all gas customers.  Indiana has not adopted any
regulation requiring gas choice except for large volume
customers.

Personnel

As of December 31, 2000, Indiana Gas had 669 employees.

The labor agreement between Indiana Gas, Local Union 1393 of the
International Brotherhood of Electrical Workers and Local Unions
7441 and 12213, United Steelworkers of America, went into effect
November 27, 1998 for a five year term expiring on December 1,
2003.  The agreement contains a 4 percent wage increase in 1998
and 3 percent wage increases each year thereafter during the term
of the agreement in addition to increased performance incentives,
a new sick pay provision and a simplified pension benefit
formula.


ITEM 2.   PROPERTIES

Indiana Gas owns and operates five gas storage fields located in
Indiana covering 71,484 acres of land with an estimated ready
delivery from storage capability of 8.0 million Dth of gas with
daily delivery capabilities of 134,160 Dth.  Indiana Gas also
maintains 186,578 Dth of gas in contract storage with a daily
deliverability of 3,563 Dth and three liquefied petroleum
(propane) air-gas manufacturing plants with a total daily
capacity of 31,000 Dth of gas.

Indiana Gas' gas delivery system includes 11,336 miles of
distribution and transmission mains.

ITEM 3.   LEGAL PROCEEDINGS

Indiana Gas is involved in various legal proceedings arising in
the normal course of business. In the opinion of management, with
the exception of matters described in Note14 of its financial
statements included in Item 8 Financial Statements and
Supplementary Data regarding transactions with ProLiance, there
are no legal proceedings pending that are material to its
financial position or results of operations.

(1)  Merger and integration related costs incurred for the year
     ended December 31, 2000 totaled $16.8 million. These costs
     relate primarily to transaction costs, severance and other
     merger and acquisition integration activities.

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

     In total, merger and integration related costs incurred for
     the year ended December 31,2000 were $28.2 million ($19.5
     million after tax).

(2)  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.

(3)  During 1997, the Indiana Gas board of directors authorized
     management to undertake the actions necessary and
     appropriate to restructure Indiana Gas' operations and
     recognize a resulting restructuring charge of $39.5 million
     ($24.5 million after tax) which included estimated costs
     related to involuntary workforce reductions.

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

                         Results of Operations

Net income was $11.2 million for the year ended December 31, 2000. Net
income before merger and integration costs of $30.7 million ($19.5
million after tax), including $11.4 million of additional operations
and maintenance expenses related to the shortened useful lives of
certain information systems to be retired in 2001 (see merger and
integration costs below), was $29.8 million for the year ended
December 31, 2000, as compared to net income of $29.7 million and
$26.8 million for 1999 and 1998, respectively.


Margin (Operating Revenues Less Cost of Gas)

Gas margin increased $3.1 million to $207.6 million, or 2 percent,
compared to the twelve-month period in 1999.  The increase reflects 7
percent (8.1 MMDth) greater throughput (combined sales and
transportation) due to much colder temperatures during the fourth
quarter of 2000 than during the fourth quarter of 1999.  Although
temperatures were 4 percent warmer than normal, temperatures during
2000 were 11 percent colder than 1999 temperatures.   Additionally,
Indiana Gas increased its customer base by 2 percent during 2000.
These favorable impacts caused residential and commercial sales to
rise 7 percent and 10 percent, respectively.

In 1999, utility margin was $204.5 million, as compared to $188.6
million for the prior year. The 1999 increase is primarily
attributable to weather being 8 percent colder than the previous year,
and the addition of new residential and commercial customers.

Total cost of gas sold was $390.5 million in 2000, $226.8 million in
1999 and $231.9 million in 1998.  Total cost of gas sold increased
$163.7 million, or 72 percent, for the year ended December 31, 2000
compared to 1999, primarily due to significantly higher average per
unit purchased gas costs.  The total average cost per Dth of gas
purchased was $5.77 in 2000, compared to $3.01 in 1999.  The price
changes are due primarily to changing commodity costs in the
marketplace.  Decreases in the average per unit cost of gas sold in
1999 as compared to 1998 more than offset the impact of the increased
throughput, causing an overall decrease in costs of gas sold in 1999
compared to 1998.

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

Operating Expenses

Indiana Gas operation and maintenance expense increased $8.0 million,
or 9 percent, for the year ended December 31, 2000, compared to 1999.
The increase is primarily attributable to increased fees from a wholly
owned subsidiary of Vectren to reflect the shortened useful lives of
certain information systems in use by Indiana Gas (see merger and
integration costs below).

Operations and maintenance expenses increased $5.9 million, or 7
percent, for 1999 as compared to 1998.  This increase is primarily due
to expenses associated with new customer information and work
management systems and rental expense related to buildings previously
owned.

<PAGE> 8

Depreciation and amortization increased $2.1 million, or 6 percent,
and $1.8 million, or 5 percent, for the years ended December 31, 2000
and 1999, respectively.  The increases reflect depreciation of normal
additions of utility plant.

Federal and state income taxes declined $9.5 million in 2000, compared
to 1999 due primarily to $28.9 million lower pre-tax earnings,
partially offset by a higher effective tax rate resulting from the non-
deductibility of certain merger costs.  Federal and state income taxes
increased $2.7 million, or 19 percent during 1999 compared to 1998 due
primarily to higher pre-tax income in 1999.

Taxes other than income taxes for 2000 were comparable to 1999 and
increased in 1999 compared to 1998 by approximately $1.8 million due
to higher property tax expense.

Merger and Integration Costs

Merger and integration costs incurred for the year ended December 31,
2000 totaled $16.8 million.  These costs relate primarily to
transaction costs, severance, and other merger and integration
activities such as signage and vehicle identification changes.
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 will be substantially completed in 2001. Merger costs are
reflected in the financial statements of the operating subsidiaries in
which merger savings are expected to be realized.

As a result of merger integration activities, Vectren management has
identified certain information systems which are expected to be
retired in 2001. Accordingly, the useful lives of these assets have
been shortened to reflect this decision. These information system
assets are owned by a wholly owned subsidiary of Vectren and the fees
allocated by the subsidiary for the use of these systems by Indiana
Gas are reflected in operation and maintenance expenses in the
accompanying financial statements. As a result of the shortened useful
lives, additional fees were incurred by Indiana Gas during 2000,
resulting in an increase in operation and maintenance expense of $11.4
million.

In total, merger and integration costs were $28.2 million, or $19.5
million after tax, in 2000.

Equity in Earnings of Unconsolidated Investments

As described in Note 2 of the financial statements included in Item 8
Financial Statements and Supplementary Data, Indiana Gas has a 47
percent undivided interest in the Ohio operations acquired by Vectren
on October 31, 2000.  Equity in earnings of unconsolidated investments
represents Indiana Gas' portion of the Ohio operations' net income
since acquisition.

Interest Expense

Interest expense for the twelve month period in 2000 increased $5.4
million, or 32 percent, compared to 1999. The increase was due
primarily to increased working capital requirements resulting from
higher natural gas prices, interest related to financing the
acquisition of the Ohio operations, and higher average interest rates
on utility debt and short-term borrowings.  Interest expense for 1999
increased $1.2 million, or 7 percent, compared to 1998 due to
increased average debt outstanding during the year and higher interest
rates.

Rate and Regulatory Matters

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.  Indiana Gas is 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, Indiana Gas may experience
higher working capital 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.

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 the IURC
Order.

As part of the agreement, among other things, the companies 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.

For further information on the agreement refer to Indiana Gas' Current
Report on Form 8-K dated March 29, 2001.

Environmental Matters

See Note 12 of Indiana Gas' financial statements in Item 8 Financial
Statements and Supplementary Data regarding manufactured gas plants.

New Accounting Standard

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.
Indiana Gas has completed the process of identifying all derivative
instruments, determining fair market

<PAGE> 10

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, Indiana Gas 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."

As of the date of adoption, Indiana Gas was not engaged in any
financial instruments affected by this statement; therefore, there was
no impact on adoption.

Liquidity and Capital Resources

Indiana Gas' capitalization objectives are 40-55 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.  Indiana Gas'
common equity component was 45 percent and 54 percent of its total
capitalization, including current maturities of long-term debt, at
December 31, 2000 and 1999, respectively.

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 revenues are lowest 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 and the investment in
the Ohio operations.

Cash Flow from Operations
Cash from operations decreased during 2000 as compared to 1999 by
approximately $74.3 million.  The decrease is primarily attributable
to merger and integration costs causing lower net income, increased
recoverable 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
$28.9 million is primarily attributable to fluctuations in prepaid gas
delivery services and other changes in working capital accounts.

Capital Expenditures and Other Investing Activities
Cash required for investing activities of $275.8 million for the year
ended December 31, 2000 include, among other things, approximately
$218 million required for the investment in the Ohio operations and
$62.4 million of capital expenditures.  This is an increase of $213.4
million over prior year due primarily to the investment in the Ohio
operations.

Cash required for investing activities in 1999 increased $16.7 million
over 1998 requirements due primarily to additional expenditures for
normal replacements and improvements of gas utility systems.
Additionally, capital expenditures for 1998 were offset by the sale of
an office building for proceeds of $9.2 million.

New construction and normal system maintenance and improvements needed
to provide service to a growing customer base will continue to require
substantial expenditures.  Capital expenditures for the five year
period 2001 - 2005 are as follows:

In millions           2001   2002   2003   2004  2005   Total
                      ----- -----  -----  -----  -----  -----
Capital expenditures  $47.7 $46.6  $47.5  $47.7  $49.0  $238.5


<PAGE> 11

Financing Activities
Cash flow from financing activities of $313.7 million for the year
ended December 31, 2000 includes $340.8 million of additional net
borrowings offset by $26.3 million of dividends on shares of common
stock.  This is an increase of $287.3 million over prior year due
primarily to funding the investment in the Ohio operations and
increased working capital requirements. Indiana Gas' investment in the
Ohio operations of approximately $218 million was funded with a
combination of short-term borrowings from VUHI and Indiana Gas'
commercial paper program.  These short-term borrowings will be
replaced over time with permanent financing.

Cash flow from financing activities in 1999 increased  $47.3 million
compared to 1998.  The change is primarily the result of increased
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.

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 beginning in 2000.  Long-term debt subject to the put
provisions during the five years following 2000 (in millions) is $0 in
2001, $6.5 in 2002, $0 in 2003, $3.5 in 2004 and $10.0 in 2005. During
2000, put provisions on $5.0 million of the notes were not exercised.

Indiana Gas' credit rating on outstanding debt at December 31, 2000
was A/A2 .  Indiana Gas' commercial paper retains an A-1/P-1 rating.

At December 31, 2000, Indiana Gas had $155 million of short-term
borrowing capacity for use in its operations, of which approximately
$20 million was available.

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 make an equity investment in Indiana
Gas to bring Indiana Gas back into compliance.  No amount is
outstanding under the back up facility.

Maturities and sinking fund requirements on long-term debt subject to
mandatory redemption during the five years following 2000 are (in
millions): $0 in 2001, $0 in 2002, $15.0 in 2003 and $15.0 in 2004,
and $0 in 2005.

ITEM 7A.   QUALITATIVE AND QUANTITATIVE DISCLOSURES OF MARKET
           RISK

Indiana Gas is exposed to market risks associated with interest rates
and counterparty risk.   The company employs a variety of risk
management policies to monitor and control these risks.  The company
does not presently utilize financial instruments for trading or
speculative purposes.

Interest Rate Risk
Indiana Gas attempts to mitigate its exposure to interest rate
fluctuations through management of its short-term borrowings.  An
internal guideline to manage short-term interest rate exposure has
been established.  This guideline targets a maximum of 25 percent of
the company's total debt portfolio to consist of adjustable rate bonds
with a maturity of less than one year, short-term notes and commercial
paper.  However, there may be times during the business cycle that the
guideline may be exceeded.  At December 31, 2000, Indiana Gas' short-
term debt including amounts owed to affiliated companies, represented
56 percent of the company's total debt portfolio, due primarily to
financing Indiana Gas' ownership interest in the $465 million
acquisition of the Ohio operations initially with short-term debt and
increased working capital requirements resulting from higher purchased
gas costs and increased customer consumption.  The short-term debt and
commercial paper utilized for acquisition of the Ohio operations will
be replaced over time with permanent financing (see Liquidity and
Capital Resources).

Counterparty Credit Risk
Indiana Gas is also exposed to counterparty credit risk when a
supplier defaults upon a contract to deliver natural gas.  To mitigate
risk, procedures to determine and monitor the creditworthiness of
counterparties have been established.

Indiana Gas Company, Inc.
Notes to Financial Statements

1. Organization and Nature of Operations

Indiana Gas Company, Inc. (Indiana Gas) provides natural gas and
transportation services to a diversified base of customers in 311
communities in 49 of Indiana's 92 counties.  It was incorporated
under the laws of the state of Indiana on July 16, 1945.

Vectren Corporation (Vectren), Indiana Gas' parent company, was
organized on June 10, 1999 solely for the purpose of effecting
the merger of Indiana Energy, Inc. (Indiana Energy), Indiana Gas'
former parent company, 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 that has been
accounted for as a pooling-of-interests.  The merger did not
affect Indiana Gas' debt securities.

Prior to the merger, all of the outstanding shares of common
stock of Indiana Gas were owned by Indiana Energy.  Subsequent to
the merger, all outstanding shares of common stock are owned by
Vectren.  Vectren is a public utility holding company.

2.  Acquisition of the 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 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."
Indiana Gas' ownership is accounted for on the equity method in
accordance with Accounting Principles Board (APB) Opinion No. 18.
Its ownership interest is included in investment in
unconsolidated affiliate in the Balance Sheets, and its interest
in the results of operations is included in equity in earnings of
unconsolidated affiliate.

Vectren Utility Holdings, Inc. (VUHI) is the intermediate holding
company for Vectren's operating public utilities, including
Indiana Gas. VUHI established a $435 million commercial paper
program to fund the majority of the acquisition.  Indiana Gas'
investment in the acquisition of approximately $218 million was
funded with a combination of short-term borrowings from VUHI and
Indiana Gas' commercial paper program.

The following table depicts unaudited summarized financial
information as to assets and liabilities of the Ohio operations
as of December 31, 2000 and its results of operations for the two
months then ended.

As of December 31, 2000:
Current assets                              $ 180,109
Noncurrent assets                             392,795
Current liabilities                           104,538
Noncurrent liabilities                            491

For the two months ended December 31, 2000:
Revenues                                    $ 111,356
Total margin                                   28,193
Operating income                                6,813
Net income                                      5,790



<PAGE> 20

3. Merger and Integration Costs
Merger and integration costs incurred for the year ended December
31, 2000 totaled $16.8 million.  These costs relate primarily to
transaction costs, severance and other merger and integration
activities such as signage and vehicle identification changes.
At March 31, 2000, Indiana Gas accrued $13.4 million of merger
and integration costs, and the accrual remaining for such costs
at December 31, 2000 is $1.3 million.  In addition, during 2000,
an additional $3.4 million of merger and integration costs were
charged directly to expense.  The merger integration activities
will be substantially completed in 2001.

As a result of merger integration activities, Vectren management
has identified certain information systems which are expected to
be retired in 2001. Accordingly, the useful lives of these assets
have been shortened to reflect this decision. These information
system assets are owned by a wholly owned subsidiary of Vectren
and the fees allocated by the subsidiary for the use of these
systems by Indiana Gas are reflected in operation and maintenance
expenses in the accompanying financial statements. As a result of
the shortened useful lives, additional fees were incurred by
Indiana Gas during 2000, resulting in an increase in operation
and maintenance expense of $11.4 million.

4.  Summary of Significant Accounting Policies

A.  Utility Plant and Depreciation
Except as described below, utility plant is stated at historical
cost and includes allocations of payroll-related costs and
administrative and general expenses, as well as an allowance for
the cost of funds used during construction. Upon normal
retirement of a depreciable unit of property, the cost is
credited to utility plant and charged to accumulated depreciation
together with the cost of removal, less any salvage. No gain or
loss is recognized upon normal retirement.

Provisions for depreciation of utility property are determined by
applying straight-line rates to the original cost of the various
classifications of property. The average depreciation rate was
3.9 percent for 2000, 3.5 percent for 1999, 3.5 percent for 1998.

B.  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.

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

Thousands                              2000     1999     1998
---------                            -------   -------  -------
Interest (net of amount capitalized) $22,903   $16,463  $15,356
Income taxes                          23,188    21,921   25,717

D.  Revenues
To more closely match revenues and expenses, Indiana Gas records
revenues for all gas delivered to customers but not billed at the
end of the accounting period.

E.    Earnings Per Share
Historical earnings per share are not presented as Vectren holds
the common shares of Indiana Gas.


<PAGE> 21

F.  Gas in Underground Storage
Gas in underground storage at December 31, 2000, was $10.9
million compared to $11.6 million at December 31, 1999.

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 $29 million and $12 million, respectively.

G.  Refundable or Recoverable Gas Cost
All metered gas rates contain a gas cost adjustment clause, which
allows for adjustment in charges for changes in the cost of
purchased gas.  Indiana Gas records 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.

H.  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 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.

                                              Year Ended

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

I.  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.

J.   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
those estimates.

K.  Regulatory Assets and Liabilities
Indiana Gas is subject to regulation by the Indiana Utility
Regulatory Commission (IURC). The accounting policies of Indiana
Gas 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:

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.

As of December 31, 2000, all of Indiana Gas' $56.7 million of
total regulatory assets are reflected in rates charged to
customers, but are not currently earning a return.  These assets
will be recovered over varying periods: $38.1 million of gas
costs, over 12 months; $4.7 million of regulatory income tax
asset, over approximately 30 years; and $13.8 million of
unamortized debt discount and expense to be recovered as
discussed above.

Indiana Gas' 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, Indiana Gas believes such accounting is appropriate.
If all or part of Indiana Gas' operations cease to meet the
criteria of SFAS 71, a write-off of related regulatory assets and
liabilities could be required.  In addition, Indiana Gas would be
required to determine any impairment to the carrying costs of
deregulated plant and inventory assets.

L.  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.  Indiana Gas 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."

As of the date of adoption, Indiana Gas was not engaged in any
financial instruments affected by this statement; therefore,
there was no impact at adoption.

5.  Capital Stock
Authorized Preferred Stock
Indiana Gas has 4 million shares of authorized and unissued
preferred stock.

Indiana Gas does not have stock-based compensation plans separate
from Vectren.  Indiana Gas' employees, officers and directors
participate in Vectren's stock-based compensation plans that
provide for awards of restricted stock and stock options to
purchase Vectren common stock at prices equal to the fair value
of the underlying shares at the date of grant.   Consistent with
Vectren, Indiana Gas accounts for participation in these plans in
accordance with Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" and related
interpretations in measuring compensation costs for its stock
options and discloses pro forma net income as if compensation
costs had been determined consistent with the SFAS No. 123,
"Accounting for Stock-based Compensation."

Had compensation cost for stock options been determined
consistent with SFAS No. 123 "Accounting for Stock-based
Compensation," net income would not have been materially
different than reported net income.

6.  Long-Term Debt
Notes payable outstanding and classified as long-term are as

Consolidated maturities and sinking fund requirements on long-
term debt subject to mandatory redemption during the five years
following 2000 are (in millions): $0 in 2001, $0 in 2002, $15.0
in 2003 and $15.0 in 2004 and $0 in 2005.

On October 5, 1999, Indiana Gas issued $30 million in principal
amount of Series G Medium-term Notes and on December 28, 2000
filed a prospectus with the Securities and Exchange Commission

<PAGE> 24

with respect to the issuance of  $70 million in debt securities.
Indiana Gas will have the option to redeem the notes prior to
their maturity dates.  The 15-Year IQ Notes may be redeemed, 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 $70 million debt issuance were
used to repay outstanding commercial paper utilized for general
corporate purposes.

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 beginning in 2000.  Long-term
debt subject to the put provisions during the five years
following 2000 (in millions) is $0 in 2001, $6.5 in 2002, $0 in
2003, $3.5 in 2004 and $10.0 in 2005. During 2000, put provisions
on $5.0 million of the notes were not exercised.

7.  Short-Term Borrowings
At December 31, 2000, Indiana Gas has approximately $155 million
of short-term borrowing capacity, of which approximately $20
million is available for operations.   See the table below for
outstanding balances and interest rates.

At December 31 (in thousands)                   2000     1999

Weighted average total outstanding during
 the year                                     $ 99,257  $38,068

At December 31, 2000, Indiana Gas was 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.   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.

See Note 14 Affiliate Transactions for further information on
short-term borrowings due to an affiliated company.

8.  Income Taxes
Vectren and subsidiary companies file a consolidated federal
income tax return.  Indiana Gas' current and deferred tax expense
is computed on a separate company basis.  The components of
income tax expense for Indiana Gas were as follows:

9.  Retirement Plans and Other Postretirement Benefits
Prior to July 1, 2000, SIGECO and Indiana Energy had separate
retirement and other postretirement benefit plans.  Effective
July 1, 2000, the SIGECO and Indiana Energy pension plans and
retirement savings plans for employees not covered by a
collective bargaining unit were merged. The pension plans and
retirement savings plans described above became Vectren plans.
As a result, the respective plan assets and plan obligations were
transferred to Vectren.

<PAGE> 26

Indiana Gas has 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 Gas' health
care costs exceed the general rate of inflation, as measured by
the Consumer Price Index (CPI).  The non-pension plans include
plans for health care and life insurance through a combination of
self-insured and fully insured plans.

The IURC has authorized 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 actuarial valuations performed for the years ended
December 31, 2000, 1999 and 1998 using a measurement date as of
September 30, 2000.  In management's opinion, disclosures from
revised actuarial valuations would not differ materially from
those presented below.

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

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
postretirement health care plan would have the following effects:

10.  Fair Value of Financial Instruments
The estimated fair values of the company's financial instruments
were as follows:

</TABLE>


Certain methods and assumptions must be used to estimate the fair
value of financial instruments.  Because of the short maturity of
notes payable and notes payable to affiliated company, the
carrying amounts approximate fair values for these financial
instruments.  The fair value of Indiana Gas' long-term debt was
estimated based on the quoted market prices for the same or
similar issues or on the current rates offered for debt of the
same remaining maturities.

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 4J ). Accordingly, any reacquisition would
not be expected to have a material effect on Indiana Gas'
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.  Commitments
Lease commitments, in millions, are $1.0 in 2001, $1.5 in 2002,
$1.6 in 2003, $1.7 in 2004, $1.8 in 2005 and $7.6 in total for
all later years. There are no leases that extend beyond 2036.
Indiana Gas has storage and supply contracts that extend up to 6
years.  Total lease expense, in millions, was approximately $1.0
in 2000, $2.0 in 1999 and $1.0 in 1998.

Indiana Gas is party to various legal proceedings arising in the
normal course of business.  In the opinion of management, with
the exception of matters described in Note 14 regarding
transactions with ProLiance Energy, LLC, there are no legal
proceedings pending against the company that are likely to be
material on the company's financial position or results of
operations.

12.  Environmental Matters
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.

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.

<PAGE> 29

Indiana Gas has recovered these estimated accrued costs from
insurance carriers and other potentially responsible parties
(PRPs).  Indiana Gas has PRP agreements in place for 19 of the 26
sites, which serve to limit Indiana Gas' share of response costs
at these 19 sites to between 20 and 50 percent.  For these sites,
Indiana Gas has accrued only its proportionate share of the
estimated response costs.

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 of approximately $20.3
million.

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.

13.  Rate and Regulatory Matters
Commodity prices for natural gas purchases during the last six
months of 2000 increased, primarily due to the expectation of a
colder winter, which led to increased demand and tighter
supplies.  Indiana Gas is typically allowed full recovery of such
charges in purchased gas costs from its retail customers through
a commission-approved gas cost adjustment.  On October 11, 2000,
Indiana Gas filed for approval of its quarterly gas cost
adjustment (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. (CAC), a not for profit consumer advocate, also has filed
with the IURC a petition to intervene and a notice of appeal of
the order.

14.  Affiliate Transactions

Vectren and certain subsidiaries of Vectren have provided certain
corporate general and administrative services to Indiana Gas
including legal, finance, tax, risk management and employee
benefits. A portion of the related costs has been allocated to
the company based on the proportion of corporate expense related
to Indiana Gas.  Indiana Gas was charged with corporate costs in
the amount of $33.3 million, $31.4 million and $25.9 million for
the years ended December 31, 2000, 1999 and 1998, respectively.

ProLiance Energy LLC, a 50 percent owned, non-regulated, energy
marketing affiliate of Vectren, 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, 1999 and 1998, totaled $401.4
million, $240.7 million and $232.2 million, respectively.

ProLiance 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.  The IURC's decision reflected the
significant gas cost savings to customers obtained through

<PAGE> 30

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 and two other pricing terms,
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.

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.

CIGMA, LLC, owned jointly and equally by a wholly owned
subsidiary of Vectren and Citizens By-Products Coal Company, a
wholly owned subsidiary of Citizens Gas, 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, 1999 and 1998 totaled $17.2
million, $17.3 million and $15.9 million, respectively.

Reliant Services, LLC , 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 for purchases of these
services totaled $3.7 million and $2.9 million for years ended
December 31, 2000 and 1999, respectively. Purchases in 1998 were
not significant.

Amounts owed to affiliates totaled $238.8 million and $6.4
million at December 31, 2000 and1999, respectively. The increase
in amounts owed to affiliates results from Indiana Gas borrowing
approximately $218 million from VUHI for Indiana Gas' investment
in the Ohio operations.  Short-term borrowings from VUHI bear
interest at 6.99 percent at December 31, 2000.

Amounts due from affiliates totaled $11.8 million and $3.0
million at December 31, 2000 and 1999, respectively.

Report of Independent Public Accountants

To the Shareholder and Board of Directors of Indiana Gas Company,
Inc.:

We have audited the accompanying balance sheets of Indiana Gas
Company, Inc. (an Indiana corporation) as of December 31, 2000
and 1999, and the related statements of income, retained earnings
and cash flows for each of the three years in the period ended
December 31, 2000. These financial statements and the schedule
referred to below are the responsibility of the company's
management. Our responsibility is to express an opinion on these
financial statements and the schedule 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 financial statements referred to above
present fairly, in all material respects, the financial position
of Indiana Gas Company, Inc. as of December 31, 2000 and 1999,
and the results of its operations and its 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.

Our audits were made for the purpose of forming an opinion on the
basic financial statements taken as a whole.  The schedule listed
under Item 14(a) (2) is presented for the purpose of complying
with the Securities and Exchange Commission's rules and is not
part of the basic financial statements.  The schedule has been
subjected to the auditing procedures applied in the audits of the
basic financial statements and, in our opinion, fairly states in
all material respects the financial data required to be set forth
therein in relation to the basic financial statements taken as a
whole.

with the Securities and Exchange Commission on March 16, 2001,
and is attached to this filing as Exhibit 99.1.  As a wholly
owned subsidiary, Indiana Gas pays its portion of Vectren's
executive compensation arrangements and plans through allocations
of Vectren's total executive compensation expense which is
reasonably related to Indiana Gas' operations.

The following tables set forth compensation allocated to Indiana
Gas' President.  No other executive officer's compensation, after
considering allocations to Indiana Gas, exceeded $100,000.  The
tables include a Summary Compensation Table (Table 1) and a table
showing the Long-Term Incentive Plan Awards in Last Fiscal Year
(Table 2).

(1)  Amounts   in   this   table  and  corresponding   footnotes
     represent   Indiana   Gas'   allocated   portion   of   the
     executive's total Vectren compensation.

(2)  The  amounts  shown  in  this  column  are  payments  under
     Indiana  Energy's Annual Management Incentive Plan.   Bonus
     payments   shown  in  1998  are  attributable  to   Indiana
     Energy's  performance  for the 1997  fiscal  year  and  the
     bonus  shown  in  1999 is attributable to Indiana  Energy's
     performance  for  the 1999 fiscal year.  The  bonus  earned
     for  the  1998  fiscal year is shown in  the  supplementary
     table.

     The  amounts earned in the period beginning April  1,  2000
     and  ending December 31, 2000 under the Vectren Corporation
     At-Risk  Incentive  Plan  have  not  been  determined   and
     approved  for  distribution by the  Vectren's  Compensation
     Committee.

(3)  The  amounts  shown  in this column are dividends  paid  on
     restricted   shares   issued  under  the   Indiana   Energy
     Executive   Restricted  Stock  Plan.   Note  that   Vectren
     adopted the Stock Plan on March 31, 2000.

(4)  The  shares  shown  in this column have  been  restated  to
     reflect  the conversion ratio of 1.333 described  above  in
     Section  titled  "Voting  Securities"  in  Vectren's  Proxy
     which   was   filed  with  the  Securities   and   Exchange
     Commission  on  March  16, 2001 and  is  attached  to  this
     filing as Exhibit 99.1.

(5)  The  amounts  shown in this column represent the  value  of
     shares   issued  under  the  Stock  Plan  and   for   which
     restrictions were lifted in each year.  At the time of  the
     merger,  Indiana  Energy executives  had  restricted  stock
     performance    grants   relating   to   open    performance
     measurement periods.  (Under normal circumstances,  at  the
     close  of  each  performance cycle, Indiana Energy's  Total
     Shareholder  Return  would have been  compared  to  a  peer
     group  and  the  number of restricted shares granted  would
     have  been  adjusted  in accordance with  the  plan.)   The
     Board  concluded  that  it  would  be  difficult,  if   not
     inappropriate,  to  use  Vectren's  performance   to   make
     adjustments to the prior grants.  Based upon the  frequency
     of  past performance grants, the Board awarded 75%  of  the
     present  value  of the potential performance  grants.   The
     value  of these grants is included in the 2000 row.  Grants
     related  to  this  closing cycle are:   Mr.  Hewitt-  2,086
     shares,  $41,397 ($17,387 allocated to Indiana  Gas).   The
     balance  of  the value in the 2000 row reflects stock  from
     other  grant cycles for which restrictions were  lifted  in
     2000 coincident with the consummation of the merger.

(6)  The   amount  shown  in  this  column  represents   several
     compensation elements.

     a)   Change-in-Control Walk-Away Provisions - Several
          Indiana Energy officers had change-in-control
          agreements at the time of the merger.  These
          agreements contained "walk-away" provisions that would
          have allowed officers to exercise their agreements
          anytime within a thirteen-month period following the
          close of the Vectren merger.  The Board felt it was
          important to maintain the continuity of the officer
          group through the merger process and asked that all
          change-in-control agreements be terminated at the
          close of the merger and new agreements be put in
          place.  Recognizing the value of the walk-away
          provision, the Board felt that officers should be
          compensated for losing the right to exercise the
          provision.  A settlement equal to 25% of the officers'
          annual base salary was made. The officer discussed in
          this section received this settlement:  Mr. Hewitt --
          $19,425.  This amount was paid in 2000.

     b)   The balance of this column reflects Vectren
          contributions to the retirement savings plan (Hewitt:
          2000 -- $4,140, 1999 -- $10,716, 1998 -- $12,925), the
          dollar value of insurance premiums paid by, or on
          behalf of, the Company and its subsidiaries with
          respect to split-dollar life insurance for the benefit
          of executive officers (Hewitt: 2000 -- $3,226, 1999 --
          $7,674, 1998 -- $7,702), credits for flexible spending
          accounts, wellness, and perfect attendance (Hewitt:
          2000 -- $63, 1999 -- $486, 1998 -- $100), deferred
          compensation contributions to restore employer
          contributions to the Company Retirement Savings Plan
          (Hewitt: 2000 -- $236, 1998 -- $175), reimbursement
          for taxable expenses (Hewitt: 2000 -- $7,369, 1999 --
          $2,999, 1998 -- $1,497), reimbursement for club dues
          (Hewitt:  2000 -- $93, 1999 -- $420, 1998 - $420), and
          dividends from Vectren stock held in the deferred
          compensation plan (Hewitt: 2000-- $1,544, 1999 --
          $2,230).

</TABLE>



(1)  Amounts  in  this  table represent the  executive's  total
     long-term incentive plan awards and are not allocated.

     This  column  shows the restricted shares  awarded  during
     fiscal  year 2000 under the Stock Plan.  The market  value
     of  the  shares  on the dates of the grants is  determined
     according  to  a  formula in the Stock Plan  based  on  an
     average  price over a period of time preceding the  grant.
     Dividends are paid directly to the holders of the stock.

(2)  For   the  grant  authorized  on  October  1,  2000,   the
     measurement  period  for  each third  of  the  grant  will
     commence on October 1, 2000, and conclude on December  31,
     2002,   2003,   and   2004.   Upon  conclusion   of   each
     measurement  period  and  subsequent  adjustment  to   the
     number  of  shares contingently granted, an  additional  1
     year  employment restriction is imposed.  The granting  of
     additional   shares,  if  any,  and  the  application   of
     forfeiture  provisions depends upon  certain  measurements
     of  Vectren's  total return to shareholders in  comparison
     to  the  total  return to shareholders of a  predetermined
     group of comparable companies.

(4)  The  initial grant shares, which are the same as the total
     number  of  shares in column (b), are also  set  forth  in
     column  (3),  are  subject  to forfeiture.   If  Vectren's
     performance  compared  to  the  peer  group  during   this
     measurement  period places it in the bottom quartile,  the
     executive officers will forfeit all of the shares  granted
     for this period.

(5)  The  initial grant shares, which are the same as the total
     number  of  shares  in column (b), are presented  in  this
     column.   If  Vectren's performance compared to  the  peer
     group  during  this measurement period places  it  in  the
     middle two quartiles, these shares will vest.

(6)  Under  the  Stock Plan, if Vectren's performance  compared
     to  the  peer  group during the initial  measuring  period
     places  it  in the top quartile, an additional performance
     grant  equal to the original grant will be made.  In  that
     event, the shares shown in column (e) will be doubled.
