                    INDIANA GAS COMPANY, INC.
                  NOTES TO FINANCIAL STATEMENTS
                           (UNAUDITED)


1.  Organization and Nature of Operations

Indiana Gas Company, Inc. (Indiana Gas) operates as a separate
wholly owned subsidiary of Vectren Corporation (Vectren) and
provides natural gas and transportation services to a diversified
base of customers in 311 communities in 49 of Indiana's 92
counties.

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 merger
did not affect Indiana Gas' debt securities.

Indiana Gas has a 47 % undivided interest in the Ohio operations
acquired by Vectren on October 31, 2000.  The Ohio operations
provide natural gas distribution and transmission services to
Dayton, Ohio and 16 counties in west central Ohio. 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 other income, net, as equity in
earnings of unconsolidated affiliate in the Statements of Income.

2.  Basis of Presentation

The interim financial statements included in this report have
been prepared by Indiana Gas, without audit, as provided in the
rules and regulations of the Securities and Exchange Commission.
Certain information and footnote disclosures normally included in
financial statements prepared in accordance with accounting
principles generally accepted in the United States have been
omitted as provided in such rules and regulations.  Indiana Gas
believes that the information in this report reflects all
adjustments necessary to fairly state the results of the interim
periods reported.  These financial statements and related notes
should be read in conjunction with Indiana Gas' audited annual
financial statements for the year ended December 31, 2000 filed
on Form 10-K.  Because of the seasonal nature of Indiana Gas'
operations, the results shown on a quarterly basis are not
necessarily indicative of annual results.

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 statements
and the reported amounts of revenues and expenses during the
reporting periods.  Actual results could differ from those
estimates.

Certain reclassifications have been made to prior period
financial statements to conform with the current year
classification. These reclassifications have no impact on
previously reported net income.

Net income                $   6,140               $ 11,930


4.  Merger and Integration Costs

Merger and integration costs incurred for the three and twelve
months ended March 31, 2001 were $.5 million and $3.7 million,
respectively.  These costs relate primarily to transaction costs,
severance, and other merger and integration activities such as
signage and vehicle identification changes. The accrual remaining
for such costs at March 31, 2001 was $1.0 million.  Merger costs
are reflected in the financial statements of the subsidiaries in
which merger savings are expected to be realized. The continued
merger integration activities will be substantially completed in
2001.

As a result of merger integration activities, Vectren 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 resulting in additional operations and
maintenance expense of approximately $3.2 million and $14.6
million for the three and twelve months ended March 31, 2001.

5.  Inventories

Inventories consist principally of gas in underground storage
valued using the last in- first out (LIFO) method.  During the
three months ended March 31, 2001, a LIFO liquidation occurred
that will be replaced by December 31, 2001.  Accordingly, the
liability created by the decrement of $1.6 million is included in
other current liabilities as of March 31, 2001.

6.  Short - Term Borrowings

At March 31, 2001, 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 and working capital
requirements associated with higher gas costs.  A waiver on the
Indiana Gas facility has been obtained to waive the non-
compliance through and including March 31, 2001 which effectively
waives the noncompliance up to June 30, 2001, the date of the
next quarterly test of the financial covenants.  Vectren
anticipates making an equity investment in Indiana Gas to bring
Indiana Gas back into compliance.  No amount is outstanding under
the back up facility.

7.  New Accounting Principle

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 and through March 31, 2001, Indiana
Gas was not engaged in any derivative or hedging activity as
defined by SFAS 133, as amended; therefore, there was no impact
at adoption or for the three and twelve months ended March 31,
2001.

8.  Contingencies

Indiana Gas is party to various legal proceedings arising in the
normal course of business.  In the opinion of management, with
the exception of the litigation matter related to ProLiance
Energy Services, LLC (See Note 11), there are no legal
proceedings pending against Indiana Gas that are likely to have a
material adverse effect on its financial position or results of
operations.

9.  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
the Indiana Department of Environmental Management (IDEM), and a
Record of Decision was issued by the 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 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.

 10

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 %.  For these sites,
Indiana Gas has accrued only its proportionate share of the
estimated response costs.

With respect to insurance coverage, as of March 31, 2001, 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.

10.  Rate and Regulatory Matters

Commodity prices for natural gas purchases have increased
significantly, primarily due to a colder winter, increased demand
and tighter supplies.  Indiana Gas is allowed full recovery of
such changes in purchased gas costs for their retail customers
through commission-approved gas cost adjustment mechanisms.

On October 11, 2000, Indiana Gas filed for approval of its
regular quarterly GCA.  In early December, the Indiana Utility
Regulatory Commission (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
Indiana Office of Utility Consumer Counselor (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 appealed the ruling.  The Citizens Action Coalition of
Indiana, Inc.(CAC), a not for profit consumer advocate, also
filed with the IURC a petition to intervene and a notice of
appeal of the order.

In March 2001, Indiana Gas reached agreement with the OUCC and
CAC regarding the IURC Order.  As part of the agreement, among
other things, Indiana Gas agreed to contribute additional amounts
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. In April 2001, the IURC issued an
order approving the settlement.

11.  Affiliate Transactions

Certain wholly owned subsidiaries of Vectren provide support
services to Indiana Gas. Services provided include corporate-
level management services, information technology, financial,
human resources, purchasing, building and fleet services. Amounts
billed by wholly owned subsidiaries of Vectren to Indiana Gas for
the three months ended March 31, 2001 and 2000 was $19.4 million
and $8.4 million, respectfully.  For the twelve months ended
March 31, 2001 and 2000, amounts billed were  $44.3 million and
$32.6, respectfully.

Indiana Gas also participates in a centralized cash management
program with its parent, affiliated companies and banks which
permits funding of checks as they are presented.

ProLiance Energy, LLC. (ProLiance), a 50 % owned, non-regulated,
energy marketing affiliate of Vectren,  provides natural gas
supply and related services to Indiana Gas.  Purchases from
ProLiance for resale and for injections into storage for the
three months ended March 31, 2001 and 2000 totaled $166.3 million
and $66.1 million, respectively; and for the twelve months ended
March 31, 2001 and 2000 totaled $501.7 million and $240.4
million, respectively.

 11

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
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. 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. The IURC has recently commenced the processing of these
further proceedings by conducting a prehearing conference.
Discovery is ongoing in the further proceeding at the current
time.

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 (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.
Purchases of these services for both the three months ended March
31, 2001 and 2000 totaled $0.7 million, and for the twelve months
ended March 31 2001 and 2000 totaled $2.8 million and $3.0
million respectively.

Amounts owed to wholly owned subsidiaries of Vectren totaled
$202.7 million, $14.2 million and $238.9 million at March 31,
2001, March 31, 2000 and December 31, 2000, respectively, and are
included in payables to affiliated company in the Balance Sheets.
Amounts due from wholly owned subsidiaries of Vectren totaled
$2.2 million and $ 11.8 at March 31, 2000 and December 31, 2000,
respectively, and are included in accounts receivable from
affiliated company in the Balance Sheets.

Amounts owed to unconsolidated affiliates of Vectren totaled
$40.0 million, $39.0 million and $97.8 million at March 31, 2001,
March 31, 2000 and December 31, 2000, respectively, and are
included in accounts payable in the Balance Sheets.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF
         OPERATIONS AND FINANCIAL CONDITION

                    INDIANA GAS COMPANY, INC.


                   Description of the Business

Indiana Gas Company, Inc. (Indiana Gas) operates as a separate
wholly owned subsidiary of Vectren Corporation (Vectren) and
provides natural gas and transportation services to a diversified
base of customers in 311 communities in 49 of Indiana's 92
counties.

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 merger
did not affect Indiana Gas' debt securities.

Indiana Gas has a 47 % undivided interest in the Ohio operations
acquired by Vectren on October 31, 2000.  The Ohio operations
provide natural gas distribution and transmission services to
Dayton, Ohio and 16 counties in west central Ohio. Indiana Gas'
ownership is accounted for on the equity method in accordance
with Accounting Principles Board 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 other income net, as in equity
earnings of unconsolidated affiliate in the Statements of Income.

                      Results of Operations

Net Income

For the three months ended March 31, 2001, net income was $15.1
million.  Net income before merger and integration costs of $3.7
million, including $3.2 million of additional operations and
maintenance expense related to the shortened useful lives of
certain information systems to be retired in 2001 (see merger and
integration costs below), was $17.4 million, compared to net
income before merger and integration costs for the first quarter
of 2000 of $18.2 million.

For the twelve months ended March 31, 2001, net income was $17.5
million.  Net income before merger and integration costs of $18.5
million, including $14.6 million of additional operations and
maintenance expense related to the shortened useful lives of
certain information systems to be retired in 2001 (see merger and
integration costs below), was $29.9 million, compared to net
income before merger and integration costs for the twelve months
ended March 31, 2000 of $24.0 million.

Utility Margin (Operating Revenues Less Cost of Gas)

Gas Utility Margin
Gas Utility margin for the three months ended March 31, 2001 of
$72.8 million was comparable to 2000.  The favorable impact of a
7 % increase in throughput to retail customers resulting from
temperatures being 15 % colder than normal and a 2 % increase in
retail customers were offset by reduced consumption and the cost
of unaccounted for gas due to much higher gas costs (see below).

Total cost of gas sold was $215.2 million for the three months
ended March 31, 2001 and $98.9 million in 2000.  This increase of
$116.3 million, or 118%, is primarily due to significantly higher
average per unit purchased gas costs. The total average cost per
dekatherm of gas purchased by Indiana Gas for the three months
ended March 31, 2001 was $7.54 compared to $3.84 for the same
period in 2000.

 13

Gas Utility margin for the twelve months ended March 31, 2001 of
$207.7 million increased $7.9 million, or 4 %, compared to 2000.
The increase is due to a 9 % increase in throughput resulting
primarily from temperatures being 26 % colder than the previous
year and a 2 % increase in residential customer base.  These
favorable impacts on gas margin were partially offset by a $3.8
million disallowance of gas costs by the Indiana Utility
Regulatory Commission (IURC) and the cost of unaccounted for gas
due to much higher gas costs.

Total cost of gas sold was $506.7 million for the twelve months
ended March 31, 2001 and $241.7 million in 2000.  This increase
of $265.0 million, or 110 %, is primarily due to significantly
higher average per unit purchased gas costs.

Commodity prices for natural gas purchases have increased
significantly, primarily due to a colder winter, 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. However, in 2001
Indiana Gas has experienced and may continue to experience higher
working capital requirements, increased expenses, including
unrecoverable interest costs, uncollectibles and unaccounted for
gas, and some level of price sensitive reduction in volumes sold.
(See Note 10 of the Financial Statements.)

Operating Expenses

Operations and Maintenance
Operations and maintenance expenses increased $1.2 million, or 5
%, for the three months ended March 31, 2001 compared to the
prior year, and operations and maintenance expenses increased
$6.3 million, or 7 %, for the twelve months ended March 31, 2001.
The increases are primarily attributable to increased fees
allocated 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).

Depreciation and Amortization
Depreciation and amortization increased $0.8 million and $2.3
million, respectively, for the three and twelve months ended
March 31, 2001 compared to the prior year due primarily to
depreciation of additions to utility plant.

Income Tax Expense
Federal and state income taxes were comparable to the prior year
for the three months ended March 31, 2001 and decreased $1.8
million for the twelve months ended March 31, 2001, compared to
the prior year periods due primarily to a normal effective tax
rate in 2001, partially offset by higher pre-tax earnings.  The
effective tax rate in 2000 was higher as a result of the non-
deductibility of certain merger and integration costs.

Taxes Other Than Income Taxes
Taxes other than income taxes increased $0.8 million and $0.7
million, respectively, for the three and twelve-month periods
ended March 31, 2001 compared to the prior year.  The increases
result from increases in gross receipts and property taxes.

Merger and Integration Costs

Merger and integration costs incurred for the three and twelve
months ended March 31, 2001 were $0.5 million and $3.7 million,
respectively.  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, which will contribute to the merger
savings, will be substantially completed in 2001. Merger costs
are reflected in the financial statements of Vectren's operating
subsidiaries in which merger savings are expected to be realized.

 14

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, resulting in an increase in operation and
maintenance expense of approximately $3.2 million and $14.6
million for the three and twelve months ended March 31, 2001.

In total, for the three months ended March 31, 2001, merger and
integration costs totaled $3.7 million ($2.3 million after tax),
compared to $13.4 million ($9.4 million after tax) for the same
period in 2000.

In total, for the twelve months ended March 31, 2001, merger and
integration costs totaled $18.5 million ($12.4 million after
tax), compared to $13.4 million ($9.4 million after tax) for the
same period in 2000.

Other Income

Equity in Earnings of Unconsolidated Affiliate
Indiana Gas has a 47 % undivided interest in the Ohio operations
acquired by Vectren on October 31, 2000. Equity in earnings of
unconsolidated affiliate represents Indiana Gas' portion of the
Ohio operations' net income.

Other Income, Net
Other income, net decreased $1.7 million and $3.1 million for the
three and twelve month periods ended March 31, 2001, compared to
2000.  The decreases are due to increased additional Low Income
Heating Assistance Program contributions. (See Note 10 of the
Financial Statements).

Interest Expense

Interest expense increased by $5.2 million, or 104 %, and $9.7
million, 55 %, respectively, for the three and twelve months
ended March 31, 2001, when compared to the prior year.  The
increases were due primarily to interest related to the financing
of the acquisition of the Ohio operations, increased working
capital requirements resulting from extremely high natural gas
prices, and higher average interest rates on utility debt and
short-term borrowings.

Liquidity and Capital Resources

Indiana Gas' capitalization objective is 40-55 % 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 47 %, 54 % and 45 % of
total capitalization, including current maturities of long-term
debt, at March 31, 2001, March 31, 2000 and December 31, 2000,
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.  However, working capital
requirements have been significantly higher during the fourth
quarter of 2000 and first quarter of 2001 due to the higher
natural gas costs.

Cash Flow from Operations
Cash flow from operations decreased during the three and twelve
months ended March 31, 2001 compared to 2000 by $17.5 million and
$95.2 million, respectively, due primarily to increased working
capital requirements due to higher gas costs, offset by
additional net income.

Indiana Gas expects the majority of its capital expenditures and
debt security redemptions to be provided by internally generated
funds.

Financing Activities
Cash flow required for financing activities of $30.4 million for
the three months ended March 31, 2001 includes $22.0 million of
reductions in net borrowings and $7.9 million common stock
dividends paid to Vectren.  This is a decrease in cash required for
financing activities when compared to the three months ended
March 31, 2000 of $7.2 million.  The decrease is primarily due to
increased payments on short-term borrowings from internally
generated funds in the prior year.

Cash flow from financing activities of $321.8 million for the
twelve months ended March 31, 2001 includes $350.0 million of
additional net borrowings offset by $28.5 million of common stock
dividends paid to Vectren.  This is an increase of $297.4 million over
the same period in the prior year due primarily to funding the
investment in the Ohio operations and increased working capital
requirements.

At March 31, 2001, Indiana Gas has approximately $155 million of
short-term borrowing capacity with third parties for use in its
operations, of which approximately $2 million is available.  On
October 31, 2000, Indiana Gas' investment in the Ohio operations
of approximately $218 million was funded with a combination of
short-term borrowings from Vectren Utility Holdings, Inc. and
Indiana Gas' commercial paper program.  These short-term
borrowings will be replaced over time with permanent financing.

At March 31, 2001, 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 and working capital
requirements associated with higher gas costs.  A waiver on the
Indiana Gas facility has been obtained to waive the non-
compliance through and including March 31, 2001 which effectively
waives the noncompliance up to June 30, 2001, the date of the
next quarterly test of the financial covenants.  Vectren
anticipates making an equity investment in Indiana Gas to bring
Indiana Gas back into compliance.  No amount is outstanding under
the back up facility.

Indiana Gas' credit rating on outstanding debt at March 31, 2001
was A/A2. Indiana Gas' commercial paper retains an A-1/P-1
rating.

Capital Expenditures and Other Investment Activities
Cash required for investing activities of $7.1 million for the
three months ended March 31, 2001 includes $8.0 million of
capital expenditures. Investing activities for the three months
ended March 31, 2000 were $15.5 million.


 16

Cash required for investing activities of $272.6 million for the
twelve months ended March 31, 2001 includes $218.1 million
required for the Ohio operations acquisition, and $54.5 million
of capital expenditures.  This is an increase of $206.3 million
over the same period in the prior year due primarily to the
investment in the Ohio operations.

New construction, normal system maintenance and improvements, and
technology investments needed to provide service to a growing
customer base will continue to require substantial expenditures.
Capital expenditures for the remainder of 2001 are estimated at
$40 million.

        transmission or distribution incidents; or availability
        due to demand, shortages, transmission problems or other
        developments; or gas pipeline system constraints.

     *  Increased competition in the energy environment
        including effects of industry restructuring and
        unbundling.

     *  Regulatory factors such as unanticipated changes in rate-
        setting policies or procedures, recovery of investments
        and costs made under traditional regulation, and the
        frequency and timing of rate increases.

     *  Financial or regulatory accounting principles or
        policies imposed by the Financial Accounting Standards
        Board, the Securities and Exchange Commission, the
        Federal Energy Regulatory Commission, state public
        utility commissions, state entities which regulate
        natural gas transmission, gathering and processing, and
        similar entities with regulatory oversight.

     *  Economic conditions including inflation rates and
        monetary fluctuations.

     *  Changing market conditions and a variety of other
        factors associated with physical energy and financial
        trading activities including, but not limited to, price,
        basis, credit, liquidity, volatility, capacity, interest
        rate, and warranty risks.

     *  Availability or cost of capital, resulting from changes
        in Vectren Corporation and its subsidiaries, interest
        rates, and securities ratings or market perceptions of
        the utility industry and energy-related industries.

 17
     *  Employee workforce factors including changes in key
        executives, collective bargaining agreements with union
        employees, or work stoppages.

     *  Legal and regulatory delays and other obstacles
        associated with mergers, acquisitions, and investments
        in joint ventures.

     *  Costs and other effects of legal and administrative
        proceedings, settlements, investigations, claims, and
        other matters, including, but not limited to, those
        described in Management's Discussion and Analysis of
        Results of Operations and Financial Condition.

     *  Changes in federal, state or local legislature
        requirements, such as changes in tax laws or rates,
        environmental laws and regulations.

any forward-looking statements, whether as a result of changes in
actual results, changes in assumptions, or other factors
affecting such statements.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET
         RISK

Indiana Gas is exposed to market risks associated with interest
rates.  The company employs a variety of risk management policies
to monitor and control these risks including the use of both
derivative and non derivative financial instruments.  The company
does not presently utilize financial instruments for trading or
speculative purposes. Indiana Gas is not currently exposed to
market risks for purchases of natural gas for its retail
customers due to current Indiana regulations which allow for
recovery of such purchases through natural gas cost adjustment
mechanisms.

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 %
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, Indiana Gas acknowledges
that there may be times during the business cycle that the
guideline may be exceeded.  At March 31, 2001, Indiana Gas' short-
term debt represented 55 % of the company's total debt portfolio,
due primarily to financing Indiana Gas' ownership interest in the
Ohio operations initially with short-term debt and the increased
working capital requirements resulting from higher purchased gas
costs and increased customer consumption.  The short-term debt
utilized for the Ohio operations acquisition will be replaced
over time with permanent financing (see Liquidity and Capital
Resources).

Market risk is estimated as the potential impact resulting from
fluctuations in interest rates on short-term borrowings,
including bank notes, lines of credit, commercial paper and notes
payable to an affiliated company.  These instruments have
interest rates indexed to short-term market interest rates.  At
March 31, 2001, March 31 2000 and December 31, 2000, the combined
borrowings under these facilities totaled $337.7  million, $50.2
million and $352.9 million, respectively.  Based upon average
borrowing rates under these facilities during the three months
ended March 31, 2001 and 2000, an increase of 100 basis points (1
%) in the rates would have increased interest expense by $0.9
million and $0.2 million.  For the twelve months ended March 31,
2001 and 2000, an increase of 100 basis points in the rates would
have increased interest expense by $1.9 million and $0.5 million,
respectively.
