PART I

ITEM 1. BUSINESS

Description of the Business

Vectren Corporation (the Company or Vectren), an Indiana corporation, is an energy and applied technology holding company headquartered in Evansville, Indiana. The Company organized on June 10, 1999, to effect the merger of Indiana Energy, Inc. (Indiana Energy) and SIGCORP, Inc. (SIGCORP). On March 31, 2000, Indiana Energy merged with SIGCORP and into Vectren. The transaction involved a tax-free exchange of shares that was accounted for as a pooling-of-interests.

The Company's wholly owned subsidiary, Vectren Utility Holdings, Inc. (VUHI), serves as the intermediate holding company for three operating public utilities:
Indiana Gas Company, Inc. (Indiana Gas), formerly a wholly owned subsidiary of Indiana Energy, Southern Indiana Gas and Electric Company (SIGECO), formerly a wholly owned subsidiary of SIGCORP, and the Ohio operations. VUHI also has other assets that provide information technology and other services to the three utilities. VUHI's consolidated operations are collectively referred to as the Utility Group. Both Vectren and VUHI are exempt from registration pursuant to
Section 3(a) (1) and 3(c) of the Public Utility Holding Company Act of 1935.

Indiana Gas provides energy delivery services to approximately 555,000 natural gas customers located in central and southern Indiana. SIGECO provides energy delivery services to approximately 136,000 electric customers and approximately 110,000 natural gas customers located near Evansville in southwestern Indiana. SIGECO also owns and operates electric generation to serve its electric customers and optimizes those assets in the wholesale power market. Indiana Gas and SIGECO generally do business as Vectren Energy Delivery of Indiana.

The Ohio operations provide energy delivery services to approximately 315,000 natural gas customers located near Dayton in west central Ohio. The Ohio operations are owned as a tenancy in common by Vectren Energy Delivery of Ohio, Inc. (VEDO), a wholly owned subsidiary, (53% ownership) and Indiana Gas (47% ownership). The Ohio operations were acquired from The Dayton Power and Light Company on October 31, 2000. The Ohio operations generally do business as Vectren Energy Delivery of Ohio.

The Company is also involved in nonregulated activities in four primary business areas: Energy Marketing and Services, Coal Mining, Utility Infrastructure Services, and Broadband. Energy Marketing and Services markets and supplies natural gas and provides energy management services, including energy performance contracting services. Coal Mining mines and sells coal and generates IRS Code Section 29 tax credits relating to the production of coal-based synthetic fuels. Utility Infrastructure Services provides underground construction and repair, facilities locating, and meter reading services. Broadband has investments in broadband communication services such as analog and digital cable television, high-speed internet and data services, and advanced local and long distance phone services. In addition, there are other businesses that invest in energy-related opportunities, real estate, and leveraged leases, among other activities. These operations are collectively referred to as the Nonregulated Group. The Nonregulated Group supports the Company's regulated utilities pursuant to service contracts by providing natural gas supply services, coal, utility infrastructure services, and other services.

Indiana Energy, incorporated under Indiana law on October 24, 1985, was engaged in natural gas distribution, gas portfolio administrative services, and marketing of natural gas, electric power and related services. Prior to the merger, Indiana Energy had fourteen subsidiaries, including ten nonregulated direct or indirect subsidiaries, a not-for-profit foundation and three utility subsidiaries, as well as investments in four nonregulated joint ventures. SIGCORP, incorporated under Indiana law on October 19, 1994, was engaged in electric generation, transmission, and distribution, natural gas distribution, coal mining, and broadband communication services. Prior to the merger, SIGCORP had eleven wholly owned subsidiaries, including ten nonregulated subsidiaries.

Narrative Description of the Business

The Company segregates its operations into three groups: a Utility Group, a Nonregulated Group, and Corporate and Other. At December 31, 2004, the Company had $3.6 billion in total assets, with $3.1 billion (86%) attributed to the Utility Group, $0.5 billion (14%) attributed to the Nonregulated Group, and less than $0.1 billion attributed to Corporate and Other. Net income for the year ended December 31, 2004, was $107.9 million, or $1.43 per share of common stock, with $83.1 million attributed to the Utility Group, $26.4 million attributed to the Nonregulated Group, and a net loss of $1.6 million attributed to Corporate and Other. Net income for the year ended December 31, 2003, was $111.2 million, or $1.58 per share of common stock. For further information regarding the activities and assets of operating segments within these Groups, refer to Note 16 in the Company's consolidated financial statements included under "Item 8 Financial Statements and Supplementary Data."

Following is a more detailed description of the Utility Group and Nonregulated Group. Corporate and Other operations are not significant.

Utility Group

The Utility Group is comprised of Vectren Utility Holdings, Inc.'s operations, which consist of the Company's regulated operations and other operations that provide information technology and other support services to those regulated operations. The Company segregates its regulated operations into a Gas Utility Services operating segment and an Electric Utility Services operating segment. The Gas Utility Services segment includes the operations of Indiana Gas, the Ohio operations, and SIGECO's natural gas distribution business and provides natural gas distribution and transportation services to nearly two-thirds of Indiana and to west central Ohio. The Electric Utility Services segment includes the operations of SIGECO's electric transmission and distribution services, which provides electric distribution services primarily to southwestern Indiana, and includes the Company's power generating and marketing operations. In total, these regulated operations supply natural gas and/or electricity to nearly one million customers. The Utility Group's other operations are generally not significant.

Gas Utility Services

At December 31, 2004, the Company supplied natural gas service to approximately 980,000 Indiana and Ohio customers, including 895,000 residential, 81,000 commercial, and 4,000 contract and other customers. This represents customer base growth of 1.2% compared to 2003.

The Company's service area contains diversified manufacturing and agriculture-related enterprises. The principal industries served include automotive assembly, parts and accessories, feed, flour and grain processing, metal castings, aluminum products, appliance manufacturing, polycarbonate resin (Lexan(R)) and plastic products, gypsum products, electrical equipment, metal specialties, glass, steel finishing, pharmaceutical and nutritional products, gasoline and oil products, and coal mining. The largest Indiana communities served are Evansville, Muncie, Anderson, Lafayette, West Lafayette, Bloomington, Terre Haute, Marion, New Albany, Columbus, Jeffersonville, New Castle, and Richmond. The largest community served outside of Indiana is Dayton, Ohio.

Revenues

For the year ended December 31, 2004, gas utility revenues were approximately $1,126.2 million, of which residential customers accounted for 66%, commercial 25%, and contract and other 9%, respectively.

The Company receives gas revenues by selling gas directly to customers at approved rates or by transporting gas through its pipelines at approved rates to customers that have purchased gas directly from other producers, brokers, or marketers. Total volumes of gas provided to both sales and transportation customers (throughput) were 200,343 MDth for the year ended December 31, 2004. Gas transported or sold to residential and commercial customers was 110,666 MDth representing 55% of throughput. Gas transported or sold to industrial and other contract customers was 89,677 MDth representing 45% of 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, the Company has storage capacity at seven active underground gas storage fields, six liquefied petroleum air-gas manufacturing plants, and a propane cavern. The Company also contracts with ProLiance Energy, LLC (ProLiance) to ensure availability of gas. ProLiance is an unconsolidated, nonregulated, energy marketing affiliate of Vectren and Citizens Gas and Coke Utility (Citizens Gas). (See the discussion of Energy Marketing & Services below and Note 3 in the Company's consolidated financial statements included in "Item 8 Financial Statements and Supplementary Data" regarding transactions with ProLiance). Periodically, purchased natural gas is injected into storage. The injected gas is then available to supplement contracted and manufactured volumes during periods of peak requirements. In addition, the Company prepays ProLiance for natural gas delivery services during the seven months prior to the peak heating season. The volume of gas per day that can be delivered during peak demand periods for each utility is located in "Item 2 Properties."

Gas Purchases

In 2004, the Company purchased 112,372 MDth volumes of gas at an average cost of $6.92 per Dth, all of which was purchased from ProLiance pursuant to contracts approved by the IURC. The average cost of gas per Dth purchased for the last five years was: $6.92 in 2004; $6.36 in 2003; $4.57 in 2002; $5.83 in 2001; and $5.60 in 2000.

Electric Utility Services

At December 31, 2004, the Company supplied electric service to approximately 136,000 Indiana customers, including 119,000 residential, and 17,000 commercial, industrial, and other customers. This represents customer base growth of 0.9% compared to 2003. In addition, the Company is obligated to provide for firm power commitments to four municipalities and to maintain spinning reserve margin requirements under an agreement with the East Central Area Reliability Group.

The principal industries served include polycarbonate resin (Lexan(R)) and plastic products, aluminum smelting and recycling, aluminum sheet products, automotive assembly, steel finishing, appliance manufacturing, pharmaceutical and nutritional products, automotive glass, gasoline and oil products, and coal mining.

Revenues

For the year ended December 31, 2004, retail and firm wholesale electricity sales totaled 6,186,160 MWh, resulting in revenues of approximately $347.5 million. Residential customers accounted for 34% of 2004 revenues; commercial 27%; industrial 31%; and municipal and other 8%. In addition, the Company sold 3,526,005 MWh through wholesale contracts in 2004, generating revenue, net of purchased power costs, of $23.8 million.

Generating Capacity

Installed generating capacity as of December 31, 2004, was rated at 1,351 MW. Coal-fired generating units provide 1,056 MW of capacity, and natural gas or oil-fired turbines used for peaking or emergency conditions provide 295 MW. Peaking capacity of 80 MW fueled by natural gas was added during 2002.

In addition to its generating capacity, in 2004, the Company had 32 MW available under firm contracts and 51 MW available under interruptible contracts. The Company also had a firm purchase supply contract for a maximum of 73 MW for the peak cooling season months during 2004.

The Company has interconnections with Louisville Gas and Electric Company, Cinergy Services, Inc., Indianapolis Power & Light Company, Hoosier Energy Rural Electric Cooperative, Inc., Big Rivers Electric Corporation, Wabash Valley Power Association, and the City of Jasper, Indiana, providing the historic ability to simultaneously interchange approximately 500 MW. However, the ability of the Company to effectively utilize the electric transmission grid in order to achieve import/export capability has been, and may continue to be, impacted. The Company, as a member of the Midwest Independent System Operator (MISO), has turned over operational control of the interchange facilities and its own transmission assets, like many other Midwestern electric utilities, to the MISO. See "Item 7 Management's Discussion and Analysis of Results of Operations and Financial Condition" regarding the Company's participation in MISO.

Total load for each of the years 2000 through 2004 at the time of the system summer peak, and the related reserve margin, is presented below in MW.


Date of summer peak load 7/13/2004 8/27/2003 8/5/2002 7/31/2001 8/17/2000

                         ----------  ---------   ---------  ---------  ---------
Total load at peak (1)       1,222       1,272      1,258       1,234      1,212

--------------------------------------------------------------------------------

(1) The total load at peak is increased 25 MW in 2003, 2002, and 2001 from the total load actually experienced. The additional 25 MW represents load that would have been incurred if summer cycler programs had not been activated. The 25 MW is also included in the interruptible contract portion of the Company's total power supply capacity. On the date of peak in 2004 and 2000, summer cycler programs were not activated.

The winter peak load for the 2003-2004 season of approximately 928 MW occurred on January 20, 2004. The prior year winter peak load was approximately 948 MW, occurring on January 27, 2003.

The Company maintains a 1.5% interest in the Ohio Valley Electric Corporation (OVEC). The OVEC is comprised of several electric utility companies, including SIGECO, and supplies power requirements to the United States Department of Energy's (DOE) uranium enrichment plant near Portsmouth, Ohio. The participating companies are entitled to receive from OVEC, and are obligated to pay for, any available power in excess of the DOE contract demand. At the present time, the DOE contract demand is essentially zero. Because of this decreased demand, the Company's 1.5% interest in the OVEC makes available approximately 32 MW of capacity, in addition to its generating capacity, for use in other operations. Such generating capacity is included in firm purchase supply in the chart above.

Fuel Costs and Purchased Power

Electric generation for 2004 was fueled by coal (95.6%) and natural gas (4.4%). Oil was used only for testing of gas/oil-fired peaking units.

There are substantial coal reserves in the southern Indiana area, and coal for coal-fired generating stations has been supplied from operators of nearby Indiana coal mines including those owned by Vectren Fuels, Inc., a wholly owned subsidiary of the Company. Approximately 3.0 million tons of coal were purchased for generating electricity during 2004, of which substantially all was supplied by Vectren Fuels, Inc. from its mines and third party purchases. The average cost of coal consumed in generating electric energy for the years 2000 through 2004 follows:

                         Year Ended December 31,
                   -------------------------------------------------------------
Avg. Cost Per        2004        2003         2002         2001          2000
                   -------     --------     -------      -------        --------
Ton                $ 27.06      $ 24.91     $ 23.50      $ 22.48         $ 22.49
MWh                  13.06        11.93       11.00        10.53           10.39

The Company also purchases power as needed from the wholesale market to supplement its generation capabilities in periods of peak demand; however, the majority of power purchased through the wholesale market is used to optimize and hedge the Company's sales to other wholesale customers. Volumes purchased in 2004 totaled 3,469,610 MWh.

Competition

The utility industry has undergone dramatic structural change for several years, resulting in increasing competitive pressures faced by electric and gas utility companies. Currently, several states, including Ohio, have passed legislation allowing electricity customers to choose their electricity supplier in a competitive electricity market and several other states are considering such legislation. At the present time, Indiana has not adopted such legislation. Ohio regulation allows gas customers to choose their commodity supplier. The Company implemented a choice program for its gas customers in Ohio in January 2003. At December 31, 2004, approximately 73,000 customers in Vectren's Ohio service territory purchase natural gas from a supplier other than the regulated utility. Margin earned for transporting natural gas to those customers, who have purchased natural gas from another supplier, are generally the same as those earned by selling gas under Ohio tariffs. Indiana has not adopted any regulation requiring gas choice; however, the Company operates under approved tariffs permitting large volume customers to choose their commodity supplier.

Regulatory and Environmental Matters

See "Item 7 Management's Discussion and Analysis of Results of Operations and Financial Condition" regarding the Company's regulated environment and other environmental matters.

Nonregulated Group

The Company is involved in nonregulated activities in four primary business areas: Energy Marketing and Services, Coal Mining, Utility Infrastructure Services, and Broadband.

Energy Marketing and Services

The Energy Marketing and Services group relies heavily upon a customer focused, value added strategy in three areas: gas marketing, performance contracting, and retail gas supply.

Gas Marketing
Gas marketing operations are performed through the Company's investment in ProLiance, a nonregulated energy marketing affiliate of Vectren and Citizens Gas. ProLiance's primary businesses include gas marketing, gas portfolio optimization, and other portfolio and energy management services. ProLiance provides these services to a broad range of municipalities, utilities, industrial operations, schools, and healthcare institutions located throughout the Midwest and Southeast United States. ProLiance's primary customers include Vectren's utilities and nonregulated gas supply operations as well as Citizens Gas. The Company, including its retail gas supply operations, contracted for all natural gas purchases through ProLiance in 2004.

In 2002, the Company integrated a wholly owned subsidiary, SIGCORP Energy Services, LLC (SES), with ProLiance. SES provided natural gas and related services to SIGECO and others prior to the transaction. In exchange for the contribution of SES' net assets totaling $19.2 million, Vectren's allocable share of ProLiance's profits and losses increased from 52.5% to 61%, consistent with Vectren's new ownership percentage. In March 2001, Vectren's allocable share of profits and losses increased from 50% to 52.5% when ProLiance began managing the Ohio operations' gas portfolio. Governance and voting rights remain at 50% for each member; and therefore, Vectren continues to account for its investment in ProLiance using the equity method of accounting.

For the year ended December 31, 2004, ProLiance's revenues, including sales to Vectren companies, exceeded $2.5 billion.

Performance Contracting
Performance-based energy contracting operations are performed through Energy Systems Group, LLC (ESG). ESG assists schools, hospitals, governmental facilities, and other private institutions to reduce energy and maintenance costs by upgrading their facilities with energy-efficient equipment. ESG's customer base is located throughout the Midwest and Southeast United States. Prior to April 2003, ESG was a consolidated venture between the Company and Citizens Gas with the Company owning two-thirds. In April 2003, the Company purchased the remaining interest in ESG.


Retail Gas Supply
Vectren Retail, LLC (d/b/a Vectren Source) provides natural gas and other related products and services in the Midwest and Southeast United States to over 100,000 residential and commercial customers opting for choice among energy providers. Vectren Source generated approximately $81.1 million in revenues in 2004, up from $44.3 million in 2003. Gas sold in 2004 approximated 9,386 MDth.

Coal Mining

The Coal Mining group provides the mining and sale of coal to the Company's utility operations and to other third parties through its wholly owned subsidiary Vectren Fuels, Inc. The Coal Mining group also generates income tax credits through IRS Code Section 29 investment tax credits relating to the production of coal-based synthetic fuels through its 8.3% ownership in Pace Carbon Synfuels, LP (Pace Carbon). The Company's investment in Pace Carbon is accounted for using the equity method of accounting. The Company's two coal mines produced 3.6 million tons in 2004, up from 3.3 million in 2003.

Utility Infrastructure Services

Utility Infrastructure Services provides underground construction and repair of utility infrastructure services to the Company and to other gas, water, and telecommunications companies as well as facilities locating and meter reading services through its investment in Reliant Services, LLC (Reliant) and Reliant's 100% ownership in Miller Pipeline, which was purchased by Reliant in 2000. Reliant is a 50% owned strategic alliance with an affiliate of Cinergy Corp. and is accounted for using the equity method of accounting.

Broadband

The Company has an approximate 2% equity interest and a convertible subordinated debt investment in Utilicom Networks, LLC (Utilicom) that if converted would bring the Company's ownership interest up to 16%. The Company also has an approximate 19% equity interest in SIGECOM Holdings, Inc., which was formed by Utilicom to hold interests in SIGECOM, LLC (SIGECOM). SIGECOM provides broadband services, such as cable television, high-speed internet, and advanced local and long distance phone services, to the greater Evansville, Indiana area. At December 31, 2004, SIGECOM had approximately 26,000 residential customers yielding over 81,000 revenue generating units indicating multiple services being utilized by the same residential customer. At December 31, 2004, there were approximately 2,000 commercial customers. SIGECOM's operations are cash flow positive and have not required any further investment since May 2002.

Other Utilicom-related subsidiaries owned franchising agreements to provide broadband services to the greater Indianapolis, Indiana and Dayton, Ohio markets. In 2004, the build out of these markets was further evaluated, and the Company concluded that it was unlikely it would make additional investments in those markets. As a result, the Company recorded charges totaling $6.0 million, or $3.6 million after-tax, to write-off investments made in the Indianapolis and Dayton markets and to write down its investment in SIGECOM.

At December 31, 2004, convertible subordinated debt investments total $31.6 million, all of which is convertible into Utilicom ownership at the Company's option or upon the event of a public offering of stock by Utilicom. The remaining equity investment in SIGECOM, LLC approximates $11.7 million.

Other Businesses

The Other Businesses group includes a variety of wholly owned operations and investments that invest in energy-related opportunities, real estate, and leveraged leases, among other investments. Major investments at December 31, 2004, include Haddington Energy Partnerships, two partnerships both approximately 40% owned; and the wholly owned subsidiaries, Southern Indiana Properties, Inc. and Energy Realty, Inc.


Personnel

As of December 31, 2004, the Company and its consolidated subsidiaries had 1,863 employees, of which 872 are subject to collective bargaining arrangements.

In July of 2004, the Company signed a three year labor agreement with Local 702 of the International Brotherhood of Electrical Workers, ending June 2007. The agreement provides a 3% wage increase in the first two years and a 3.5% increase in the third year of the agreement. The agreement also provides for improvements in pension benefits and a multi-tiered health plan in which the employees pay 16% of the cost.

In January 2004, the Company signed a five year labor agreement, ending December 2008, with Local 1393 of the International Brotherhood of Electrical Workers and United Steelworkers of America Locals 12213 and 7441. The agreement provides for annual wage increases of 3%, a multi-tiered health care plan in which the employees pay 12% to 16% of the premium, and pension enhancements for early retirees.

The Company's contract with Local 135 of the Teamsters, Chauffeurs, Warehousemen, and Helpers will expire in September 2005. The Company's contract with Local 175, Utility Workers Union of America will expire in October 2005.

Results

For the year ended December 31, 2004, reported earnings were $107.9 million, or $1.43 per share compared to $111.2 million, or $1.58 per share, in 2003 and $114.0 million, or $1.69 in 2002. The Company experienced significant earnings growth from its Energy Marketing and Services, Coal Mining, and Utility Infrastructure Services nonregulated businesses during 2004 and 2003. Earnings from utility operations were slightly lower in 2004 due largely to mild weather in 2004, offset somewhat by customer growth and the effects of gas base rate increases at two of the three utilities. Mild weather also impacted 2003 results compared to 2002, along with the write off of an investment.

While earnings have slightly decreased, earnings per share was further affected by an equity offering of 7.4 million shares in August of 2003. The additional shares diluted earnings per share in 2004 as compared to 2003 by $0.10 and in 2003 as compared to 2002 by $0.07. The equity offering netted proceeds of approximately $163 million.

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

The Nonregulated Group generates revenue or earnings from the provision of services to customers. The activities of the Nonregulated Group are closely linked to the utility industry, and the results of those operations are generally impacted by factors similar to those impacting the overall utility industry.

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

Dividends

Dividends declared for the year ended December 31, 2004, were $1.15 per share compared to $1.11 per share in 2003 and $1.07 per share in 2002. In October 2004, the Company's board of directors increased its quarterly dividend to $0.295 per share from $0.285 per share.

Detailed Discussion of Results of Operations

Following is a more detailed discussion of the results of operations of the Company's Utility Group and Nonregulated Group. The detailed results of operations for the Utility Group and Nonregulated Group are presented and analyzed before the reclassification and elimination of certain intersegment transactions necessary to consolidate those results into the Company's Consolidated Statements of Income. Corporate and Other operations are not significant.
Results of Operations of the Utility Group

The Utility Group is comprised of Vectren Utility Holdings, Inc.'s operations, which consist of the Company's regulated operations and other operations that provide information technology and other support services to those regulated operations. The Company segregates its regulated operations into a Gas Utility Services operating segment and an Electric Utility Services operating segment. The Gas Utility Services segment provides natural gas distribution and transportation services to nearly two-thirds of Indiana and to west central Ohio. The Electric Utility Services segment provides electric distribution services primarily to southwestern Indiana, and includes the Company's power generating and marketing operations. In total, these regulated operations supply natural gas and/or electricity to nearly one million customers. The results of operations of the Utility Group before certain intersegment eliminations and reclassifications for the years ended December 31, 2004, 2003, and 2002, follow:

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

In 2004, Utility Group earnings were $83.1 million as compared to $85.6 million in 2003. The 2004 earnings decline is due to the impact of unfavorable weather, estimated at $5 million after tax, or $0.07 per share. Margin growth, offsetting the weather impact, results from the recovery of NOx related environmental expenditures, gas base rate increases implemented in 2004, and customer growth. The primary expense changes were higher depreciation and lower bad debt expense in 2003. Bad debt expense in 2003 associated with the Ohio service territory was reversed and deferred for later recovery under an uncollectible accounts expense rider.

The $11.5 million decrease in earnings occurring in 2003 compared to 2002 was primarily due to increased operating expenses and the write-off of an investment, partially offset by increased wholesale power margins and retail electric rate recovery related to NOx compliance expenditures. An increase in the Indiana state income tax rate to 8.5% from 4.5% also contributed to the decrease.

During 2004 and 2003, the Company initiated base rate cases in its three gas service territories. Orders in its two Indiana service territories were received in the second half of 2004. An order in the Ohio territory is expected late in the first quarter of 2005. On an annual basis, the Indiana orders will increase margins an estimated $30 million, and during 2004 provided additional margin of $4.7 million. The Company has sought and received regulatory recovery mechanisms (trackers) affecting electric margin that provide a return on utility plant constructed for environmental compliance and that allow for recovery of related operating expenses. After tax earnings associated with the NOx compliance trackers totaled $9.0 million in 2004, $4.7 million in 2003 and $1.1 million in 2002. The Company has also utilized regulatory trackers affecting gas margin that recover, on a dollar-for-dollar basis, pipeline integrity management costs in its Indiana territories and uncollectible accounts expense, operating expenses related to choice implementation costs, and other costs in its Ohio service territory.

Throughout this discussion, the terms Gas Utility margin and Electric Utility margin are used. Gas Utility margin and Electric Utility margin could be considered non-GAAP measures of income. Gas Utility margin is calculated as Gas utility revenues less the Cost of gas. Electric Utility margin is calculated as Electric utility revenues less Fuel for electric generation and Purchased electric energy. These measures exclude Other operating expenses, Depreciation and amortization, and Taxes other than income taxes, which are included in the calculation of operating income. The Company believes Gas Utility and Electric Utility margins are better indicators of relative contribution than revenues since gas prices and fuel costs can be volatile and are generally collected on a dollar-for-dollar basis from customers. Margins should not be considered an alternative to, or a more meaningful indicator of, operating performance than operating income or net income as determined in accordance with accounting principles generally accepted in the United States.

Significant Fluctuations

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

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

Gas utility margins were $347.7 million for the year ended December 31, 2004. This represents a decrease in gas utility margin of $2.1 million compared to 2003. Heating weather for the year ended December 31, 2004, was 8% warmer than normal and 8% warmer than the prior year. The estimated unfavorable impact on gas utility margin caused by weather was approximately $9.8 million compared to 2003. Indiana base rate increases added $4.7 million compared to the prior year. Also offsetting the effects of weather were increased late and reconnect fees, expense recovery pursuant to Ohio regulatory trackers, and higher revenue taxes collected from rate payers. Gas sold and transported volumes were 4% less in 2004, compared to the prior year. The decreased throughput was primarily attributable to weather. The average cost per dekatherm of gas purchased was $6.92 in 2004; $6.36 in 2003, and $4.57 in 2002.

Gas Utility margin for the year ended December 31, 2003, of $349.8 million increased $12.6 million, or 4%, compared to 2002. It is estimated that weather near normal for the year and 6% cooler than the prior year, contributed $8 million in increased residential and commercial margin and was the primary contributor to increased throughput compared to 2002. The remaining increase is primarily attributable to $4.5 million in higher revenue taxes on higher gas costs and volumes sold and $1.8 million in recovery of Ohio customer choice implementation costs.

Retail & Firm Wholesale Margin

Native load and firm wholesale margin was $239.5 million for the year ended December 31, 2004. This represents a $24.8 million increase over 2003. Additional NOx recoveries increased margin $14.6 million in 2004. Cooling weather for the year was 12% warmer than last year, increasing margin an estimated $2.0 million. The remaining increase in margin was attributable to increased small customer usage and increased sales to industrial customers. Due to the above factors, volumes sold increased 5% to 6.19 GWh for 2004, compared to 5.90 GWh in 2003. Volumes sold in 2002 were 6.19 GWh.

For the year ended December 31, 2003, margin from serving native load and firm wholesale customers was $214.7 million, a decrease of $2.8 million when compared to 2002. It is estimated that summer weather, 19% cooler than normal and 34% cooler than 2002, caused an $8 million decrease in residential and commercial margin. The effect of weather was partially offset by a $7.4 million increase in retail electric rates related to recovery of and return on NOx compliance expenditures and related operating expenses. A slowly recovering economy continued to negatively impact industrial sales which decreased $1.4 million compared to 2002. As a result of primarily mild weather and slow economic conditions, retail and firm wholesale volumes sold decreased 5%.

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

Following is a reconciliation of asset optimization activity:

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

Net wholesale margins decreased $3.3 million compared to 2003 due to reduced available capacity. The availability of excess capacity was impacted by scheduled outages of owned generation, related to the installation of environmental compliance equipment and an increase in demand by native load customers due to both weather and increased usage. The $5.6 million increase in 2003 compared to 2002 was primarily due to price volatility and additional capacity due to weather.

Utility Group Operating Expenses

Other Operating

Other operating expenses increased $8.4 million for the year ended December 31, 2004 as compared to 2003. Expense in 2003 reflects the deferral of $4.0 million relating to the Ohio order allowing the Company to defer for future recovery its actual bad debt expense in excess of the amount provided in base rates (See Rate and Regulatory Matters below). Other factors contributing to the increase were an increase in NOx-related expenses of $2.6 million recovered in rates and planned turbine maintenance of $1.9 million.

Other operating expense increased $11.5 million in 2003 compared to 2002. The increase was principally caused by increased distribution, plant, and transmission operating expenses; power plant and other maintenance; customer service initiatives; higher insurance premiums; and prior year insurance recoveries. In addition, operating expenses reflect $1.8 million in amortization of Ohio choice implementation costs, which are recovered through increased gas utility margin. The increase in operating expenses was partially offset by the impact of an Ohio regulatory order, which resulted in the reversal and deferral of 2003 uncollectible accounts expense of $4.0 million for future recovery.

Depreciation & Amortization
For the year ended December 31, 2004, depreciation expense increased $9.9 million compared to 2003. NOx-related depreciation contributed $4.8 million of the increase with the remaining increase due primarily to normal additions to utility plant. The increase of $7.2 million in 2003 compared to 2002 is also due to normal additions to utility plant. In addition to the NOx scrubbers placed into service in 2004, other significant expenditures included upgrades of electric facilities subjected to storm damage, construction of a new substation, and a new transmission main. Upgrades implemented in 2002 and 2003 now included in annual depreciation expense include a gas-fired peaker unit, expenditures for implementing a choice program for Ohio gas customers, customer system upgrades, and other upgrades to existing transmission and distribution facilities.

Taxes Other Than Income Taxes
Taxes other than income taxes increased $1.6 million in 2004 compared to 2003 and $5.9 million in 2003 compared to 2002. Almost all of the 2004 increase and $4.5 million of the 2003 increase corresponds with increased collections of utility receipts and excise taxes due to higher revenues. The remaining 2003 increase results principally from higher property taxes.


Utility Group Other Income (Expense)

Total other income (expense)-net increased $1.1 million during 2004 compared to 2003 and decreased $1.0 million during 2003 compared to 2002. Lower amounts of AFUDC were recorded in 2004 as NOx expenditures were placed in service. Fiscal year 2003 includes operating losses and the write-off of investments in an entity that processes fly ash, totaling $4.2 million. In 2002, the Company recognized losses associated with those investments totaling $1.5 million.

Utility Group Interest Expense

In the second half of 2003, the Company completed permanent financing transactions in which approximately $366 million in equity, debt, and hedging net proceeds were received and used to retire higher coupon long-term debt and other short term borrowings. The changes in interest expense in 2004 and 2003 reflect the full impact of that transaction.

Utility Group Income Taxes

For the year ended December 31, 2004, income taxes were relatively consistent with 2003 with decreased earnings offset by a slightly higher effective rate. An increase in the Indiana state income tax rate from 4.5% to 8.5% was the primary reason for increased tax expense in 2003 compared to 2002.

Environmental Matters

The Company is subject to federal, state, and local regulations with respect to environmental matters, principally air, solid waste, and water quality. Pursuant to environmental regulations, the Company is required to obtain operating permits for the electric generating plants that it owns or operates and construction permits for any new plants it might propose to build. Regulations concerning air quality establish standards with respect to both ambient air quality and emissions from electric generating facilities, including particulate matter, sulfur dioxide (SO2), and nitrogen oxide (NOx). Regulations concerning water quality establish standards relating to intake and discharge of water from electric generating facilities, including water used for cooling purposes in electric generating facilities. Because of the scope and complexity of these regulations, the Company is unable to predict the ultimate effect of such regulations on its future operations, nor is it possible to predict what other regulations may be adopted in the future. The Company intends to comply with all applicable governmental regulations, but will contest any regulation it deems to be unreasonable or impossible with which to comply.

Clean Air Act

NOx SIP Call Matter
The Company has taken steps to comply with Indiana's State Implementation Plan (SIP) of the Clean Air Act (the Act). These steps include installing Selective Catalytic Reduction (SCR) systems at Culley Generating Station Unit 3 (Culley), Warrick Generating Station Unit 4, and A.B. Brown Generating Station Units 1 and
2. SCR systems reduce flue gas NOx emissions to atmospheric nitrogen and water using ammonia in a chemical reaction. This technology is known to currently be the most effective method of reducing nitrogen oxide (NOx) emissions where high removal efficiencies are required.

The IURC has issued orders that approve:
o the Company's project to achieve environmental compliance by investing in clean coal technology;
o a total capital cost investment for this project up to $244 million (excluding AFUDC), subject to periodic review of the actual costs incurred;
o a mechanism whereby, prior to an electric base rate case, the Company may recover through a rider that is updated every six months, an 8% return on its weighted capital costs for the project; and
o ongoing recovery of operating costs, including depreciation and purchased emission allowances, related to the clean coal technology once the facility is placed into service.

Based on the level of system-wide emissions reductions required and the control technology utilized to achieve the reductions, the current estimated construction cost is consistent with amounts approved in the IURC's orders. Through December 31, 2004, $238 million has been expended, and three of the four SCR's are operational. Once all equipment is installed and operational, related annual operating expenses, including depreciation expense, are estimated to be between $24 million and $27 million. The Company is recovering the operational costs associated with the SCR's and related technology. The 8% return on capital investment approximates the return authorized in the Company's last electric rate case in 1995 and includes a return on equity.

The Company has achieved timely compliance through the reduction of the Company's overall NOx emissions to levels compliant with Indiana's NOx emissions budget allotted by the USEPA. Therefore, the Company has recorded no accrual for potential penalties that may result from noncompliance.

Culley Generating Station Litigation
During 2003, the U.S. District Court for the Southern District of Indiana entered a consent decree among SIGECO, the Department of Justice (DOJ), and the USEPA that resolved a lawsuit originally brought by the USEPA against SIGECO. The lawsuit alleged violations of the Clean Air Act by SIGECO at its Culley Generating Station for (1) making modifications to generating station without obtaining required permits, (2) making major modifications to the generating station without installing the best available emission control technology, and
(3) failing to notify the USEPA of the modifications.

Under the terms of the agreement, the DOJ and USEPA agreed to drop all challenges of past maintenance and repair activities at the Culley Generating Station. In reaching the agreement, SIGECO did not admit to any allegations in the government's complaint, and SIGECO continues to believe that it acted in accordance with applicable regulations and conducted only routine maintenance on the units. SIGECO entered into this agreement to further its continued commitment to improve air quality and avoid the cost and uncertainties of litigation.

Under the agreement, SIGECO committed to
o either repower Culley Unit 1 (50 MW) with natural gas and equip it with SCR control technology for further reduction of nitrogen oxide, or cease operation of the unit by December 31, 2006;
o operate the existing SCR control technology recently installed on Culley Unit 3 (287 MW) year round at a lower emission rate than that currently required under the NOx SIP Call, resulting in further nitrogen oxide reductions;
o enhance the efficiency of the existing scrubber at Culley Units 2 and 3 for additional removal of sulphur dioxide emissions;
o install a baghouse for further particulate matter reductions at Culley Unit 3 by June 30, 2007;
o conduct a Sulphuric Acid Reduction Demonstration Project as an environmental mitigation project designed to demonstrate an advance in pollution control technology for the reduction of sulfate emissions; and
o pay a $600,000 civil penalty.

The Company notified the USEPA of its intention to shut down Culley Unit 1 effective December 31, 2006. The Company does not believe that implementation of the settlement will have a material effect to its results from operations or financial condition. The $600,000 civil penalty was expensed and paid during 2003 and is reflected in Other-net.

Information Request
On January 23, 2001, SIGECO received an information request from the USEPA under
Section 114 of the Clean Air Act for historical operational information on the Warrick and A.B. Brown generating stations. SIGECO has provided all information requested with the most recent correspondence provided on March 26, 2001.

Manufactured Gas Plants

In the past, Indiana Gas, SIGECO, 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, SIGECO, and 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 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 the IDEM's Voluntary Remediation Program (VRP) and is currently conducting some level of remedial activities, including groundwater monitoring at certain sites, where deemed appropriate, and will continue remedial activities at the sites as appropriate and necessary.

In conjunction with data compiled by environmental consultants, Indiana Gas has accrued the estimated costs for further investigation, remediation, groundwater monitoring, and related costs for the sites. While the total costs that may be incurred in connection with addressing these sites cannot be determined at this time, Indiana Gas has recorded costs that it reasonably expects to incur totaling approximately $20.4 million.

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

With respect to insurance coverage, Indiana Gas has received and recorded settlements from all known insurance carriers in an aggregate amount approximating $20.4 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.

In October 2002, the Company received a formal information request letter from the IDEM regarding five manufactured gas plants owned and/or operated by SIGECO and not currently enrolled in the IDEM's VRP. In response, SIGECO submitted to the IDEM the results of preliminary site investigations conducted in the mid-1990's. These site investigations confirmed that based upon the conditions known at the time, the sites posed no risk to human health or the environment. Follow up reviews have been initiated by the Company to confirm that the sites continue to pose no such risk.

On October 6, 2003, SIGECO filed applications to enter four of the manufactured gas plant sites in IDEM's VRP. The remaining site is currently being addressed in the VRP by another Indiana utility. SIGECO added those four sites into the renewal of the global Voluntary Remediation Agreement that Indiana Gas has in place with IDEM for its manufactured gas plant sites. That renewal was approved by the IDEM on February 24, 2004. On July 13, 2004, SIGECO filed a declaratory judgment action against its insurance carriers seeking a judgment finding its carriers liable under the policies for coverage of further investigation and any necessary remediation costs that SIGECO may accrue under the VRP program. The total investigative costs, and if necessary, costs of remediation at the four SIGECO sites, as well as the amount of any PRP or insurance recoveries, cannot be determined at this time.

Jacobsville Superfund Site

On July 22, 2004, the USEPA listed the Jacobsville Neighborhood Soil Contamination site in Evansville, Indiana, on the National Priorities List under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). The USEPA has identified four sources of historic lead contamination. These four sources shut down manufacturing operations years ago. When drawing up the boundaries for the listing, the USEPA included a 250 acre block of properties surrounding the Jacobsville neighborhood, including Vectren's Wagner Operations Center. Vectren's property has not been named as a source of the lead contamination, nor does the USEPA's soil testing to date indicate that the Vectren property contains lead contaminated soils. Vectren's own soil testing, completed during the construction of the Operations Center, did not indicate that the Vectren property contains lead contaminated soils. At this time, Vectren anticipates only additional soil testing, if required by the USEPA.

Rate and Regulatory Matters

Gas and electric operations with regard to retail rates and charges, terms of service, accounting matters, issuance of securities, and certain other operational matters specific to its Indiana customers are regulated by the IURC. The retail gas operations of the Ohio operations are subject to regulation by the PUCO.

All metered gas rates in Indiana contain a gas cost adjustment (GCA) clause, and all metered gas rates in Ohio contain a gas cost recovery (GCR) clause. GCA and GCR clauses allow the Company to charge for changes in the cost of purchased gas. Metered electric rates contain a fuel adjustment clause (FAC) that allows for adjustment in charges for electric energy to reflect changes in the cost of fuel. The net energy cost of purchased power, subject to an agreed upon benchmark, is also recovered through regulatory proceedings. Rate structures in the Company's territories do not include weather normalization-type clauses that authorize the utility to recover gross margin on sales established in its last general rate case, regardless of actual weather patterns.

GCA, GCR, and FAC procedures involve periodic filings and IURC and PUCO hearings to establish the amount of price adjustments for a designated future period. The procedures also provide for inclusion in later periods of any variances between the estimated cost of gas, cost of fuel, and net energy cost of purchased power and actual costs incurred. The Company records any under-or-over-recovery resulting from gas and fuel adjustment clauses each month in margin. A corresponding asset or liability is recorded until the under-or-over-recovery is billed or refunded to utility customers.

The IURC has also applied the statute authorizing GCA and FAC procedures to reduce rates when necessary to limit net operating income to a level authorized in its last general rate order through the application of an earnings test. For the recent past, the earnings test has not affected the Company's ability to recover costs, and the Company does not anticipate the earnings test will restrict recovery in the near future.

SIGECO and Indiana Gas Base Rate Settlements On June 30, 2004, the IURC approved a $5.7 million base rate increase for SIGECO's gas distribution business, and on November 30, 2004, approved a $24 million base rate increase for Indiana Gas' gas distribution business. The new rate designs include a larger service charge, which is intended to address to some extent earnings volatility related to weather. The base rate change in SIGECO's service territory was implemented on July 1, 2004, resulting in additional 2004 revenues of $2.5 million. The base rate change in Indiana Gas' service territory was implemented on December 1, 2004, resulting in additional 2004 revenues of $2.2 million.

The orders also permit SIGECO and Indiana Gas to recover the on-going costs to comply with the federal Pipeline Safety Improvement Act of 2002. The Pipeline Safety Improvement Tracker provides for the recovery of incremental non-capital dollars, capped at $750,000 the first year and $500,000 thereafter for SIGECO and $2.5 million per year for Indiana Gas. Any costs incurred in excess of these annual caps are to be deferred for future recovery.

VEDO Pending Base Rate Increase Settlement On February 4, 2005, the Company filed with the PUCO a settlement agreement that had been entered into with several parties, including the PUCO staff, in its base rate case. The Ohio Office of the Consumer Counselor (OCC) is opposing the settlement. Earlier in 2004 VEDO had filed with the PUCO a request to adjust its base rates and charges for its gas distribution business serving more than 315,000 customers located in west central Ohio. The settlement provides for a $15.7 million increase in VEDO's base distribution rates to cover the ongoing costs of operating, maintaining, and expanding the approximately 5,200-mile distribution system. The settlement increase includes $1.1 million of funding for weatherization and conservation programs for low income customers. Evidentiary hearings were completed in the case on February 9, 2005. Review and approval by the PUCO is necessary before the settlement is effective. The proposed new rate design includes a larger service charge, which will address, to some extent, earnings volatility related to weather. The settlement also permits VEDO the annual recovery of on-going costs associated with the Pipeline Safety Improvement Act of 2002. Based upon the PUCO's actions in other proceedings, the Company would expect an order near the end of the first quarter of 2005.

Ohio Uncollectible Accounts Expense Tracker On December 17, 2003, the PUCO approved a request by VEDO and several other regulated Ohio gas utilities to establish a mechanism to recover uncollectible account expense outside of base rates. The tariff mechanism establishes an automatic adjustment procedure to track and recover these costs instead of providing the recovery of the historic amount in base rates. Through this order, VEDO received authority to defer its 2003 uncollectible accounts expense to the extent it differs from the level included in base rates. The Company estimated the difference to approximate $4 million in excess of that included in base rates, and reversed and deferred that amount for future recovery. In 2004, the Company recorded revenues of $3.3 million which is equal to the level of uncollectible accounts expense recognized for Ohio residential customers.

Gas Cost Recovery (GCR) Audit Proceedings There is an Ohio requirement that Ohio gas utilities undergo a biannual audit of their gas acquisition practices in connection with the gas cost recovery (GCR) mechanism. In the case of VEDO, a two-year audit period ended in November 2002. That audit period provided the PUCO staff its initial review of the portfolio administration arrangement between VEDO and ProLiance. The external auditor retained by the PUCO staff submitted an audit report in the fall of 2003 wherein it recommended a disallowance of approximately $7 million of previously recovered gas costs. The Company believes a large portion of the third party auditor recommendations is without merit. A hearing has been held, and the PUCO staff has recommended a $6.1 million disallowance. The Ohio Consumer Counselor has recommended an $11.5 million disallowance. For this PUCO audit period, any disallowance relating to the Company's ProLiance arrangement will be shared by the Company's joint venture partner. Based on a review of the matters, the Company has recorded $1.1 million for its estimated share of a potential disallowance. A PUCO decision on this matter is yet to be issued. The Company is also unable to determine the effects that a PUCO decision for the audit period ended in November 2002 may have on results in audit periods beginning after November 2002.

Other Operating Matters

MISO

The FERC approved the Midwest Independent System Operator (MISO) as the nation's first regional transmission organization. Regional transmission organizations place public utility transmission facilities in a region under common control. The MISO is committed to reliability, the nondiscriminatory operation of the bulk power transmission system, and to working with all stakeholders to create cost-effective and innovative solutions. The Carmel, Indiana, based MISO began operations in December 2001 and serves the electrical transmission needs of much of the Midwest. In December 2001, the IURC approved the Company's request for authority to transfer operational control over its electric transmission facilities to the MISO. That transfer occurred on February 1, 2002. Pursuant to an order from the IURC, certain MISO costs have been deferred for future recovery.

During 2004, SIGECO together with three other Indiana electric utilities filed a proceeding with the IURC seeking to recover the anticipated costs associated with MISO's implementation of the "Day 2 energy market" on April 1, 2005. A hearing considering this request occurred in February, 2005.

As a result of MISO's operational control over much of the Midwestern electric transmission grid, including SIGECO's transmission facilities, SIGECO's continued ability to import power, when necessary, and export power to the wholesale market has been, and may continue to be, impacted. Given the nature of MISO's policies regarding use of transmission facilities, as well as ongoing FERC initiatives and uncertainties around the "Day 2 energy market" operations, it is difficult to predict near term operational impacts. However, as stated above, it is believed that MISO's regional operation of the transmission system will ultimately lead to reliability improvements.

The potential need to expend capital for improvements to the transmission system, both to SIGECO's facilities as well as to those facilities of adjacent utilities, over the next several years will become more predictable as MISO completes studies related to regional transmission planning and improvements. Such expenditures may be significant.


United States Securities and Exchange Commission Inquiry into PUCHA Exemption

In July 2004, the Company received a letter from the SEC regarding its exempt status under the Public Utility Holding Company Act of 1935 (PUHCA). The letter asserts that Vectren's out of state electric power sales exceed the amount previously determined by the SEC to be acceptable in order to qualify for the exemption. There is pending a request by Vectren for an order of exemption under
Section 3(a)(1) of PUHCA. Vectren also claims the benefit of the exemption pursuant to Rule 2 under Section 3(a)(1) of PUHCA by filing an annual statement on SEC Form U-3A-2. The Company has responded to the SEC inquiry and filed an amended Form U-3A-2 for the year ended December 31, 2003. The amendment changed the method of aggregating wholesale power sales and purchases outside of Indiana from that previously reported. The new method is to aggregate by delivery point. The amendment also submitted clarifications as to activity outside of Indiana related to gas utility operations.

Results of Operations of the Nonregulated Group

The Nonregulated Group is comprised of four primary business areas: Energy Marketing and Services, Coal Mining, Utility Infrastructure Services, and Broadband. Energy Marketing and Services markets and supplies natural gas and provides energy management services, including energy performance contracting services. Coal Mining mines and sells coal and generates IRS Code Section 29 investment tax credits relating to the production of coal-based synthetic fuels. Utility Infrastructure Services provides underground construction and repair, facilities locating, and meter reading services. Broadband has investments in broadband communication services such as analog and digital cable television, high-speed internet and data services, and advanced local and long distance phone services. In addition, the Nonregulated Group has other businesses that invest in energy-related opportunities, real estate, and leveraged leases, among other activities. The Nonregulated Group supports the Company's regulated utilities pursuant to service contracts by providing natural gas supply services, coal, utility infrastructure services, and other services. Corporate expenses are allocated to each business area. The results of operations of the Nonregulated Group for the years ended December 31, 2004, 2003, and 2002, follow:

Nonregulated earnings for the year ended December 31, 2004, were $26.4 million compared to $27.6 million in 2003 and $19.0 million in 2002. The Company's three core nonregulated businesses, Energy Marketing and Services, Coal Mining, and Utility Infrastructure Services, contributed $30.9 million in 2004, compared to $27.4 million in 2003 and $22.4 million in 2002. The 2004 results reflect $6.0 million in after tax charges related to the write-down of the Company's broadband businesses. Those charges were partially offset by net gains from the Company's investment in Haddington Energy Partners. Earnings in 2003 reflect after tax gains from the divesture of businesses and investments totaling $2.6 million after tax.

Energy Marketing & Services

Energy Marketing and Services is comprised of the Company's gas marketing operations, performance contracting operations, and retail gas supply operations.

Gas marketing operations are performed through the Company's investment in ProLiance Energy LLC (ProLiance), a nonregulated energy marketing affiliate of Vectren and Citizens Gas and Coke Utility (Citizens Gas). ProLiance's primary businesses include gas marketing, gas portfolio optimization, and other portfolio and energy management services. ProLiance's primary customers include Vectren's utilities and nonregulated gas supply operations as well as Citizen's Gas and other large end-use customers. As part of a settlement agreement approved by the IURC during July 2002, the gas supply agreements with Indiana Gas and SIGECO, were approved and extended through March 31, 2007. The utilities may decide to conduct a "request for proposal" (RFP) for a new supply administrator, or they may decide to make an alternative proposal for procurement of gas supply. That decision will be made by December 2005. To the extent an RFP is conducted, ProLiance has the opportunity, if it so elects, to participate in the RFP process for service to the utilities after March 31, 2007.

In June 2002, the integration of Vectren's wholly owned gas marketing subsidiary, SIGCORP Energy Services, LLC (SES), with ProLiance was completed. SES provided natural gas and related services to SIGECO and others prior to the integration. In exchange for the contribution of SES' net assets totaling $19.2 million, Vectren's allocable share of ProLiance's profits and losses increased to 61%, consistent with Vectren's new ownership percentage. The transfer of net assets was accounted for at book value, consistent with joint venture accounting, and did not result in any gain or loss. Governance and voting rights remain at 50% for each member; and therefore, Vectren continues to account for its investment in ProLiance using the equity method of accounting.

Energy Systems Group, LLC (ESG) provides energy performance contracting and facility upgrades through its design and installation of energy-efficient equipment throughout the Midwest. ESG acquired Progress Energy Solutions during 2004, expanding its operations throughout the Southeast and Mid-Atlantic United States. Prior to April 2003, ESG was a consolidated venture between the Company and Citizens Gas with the Company owning two-thirds. In April 2003, the Company purchased the remaining interest in ESG.

Vectren Retail, LLC (d/b/a Vectren Source) provides natural gas and other related products and services in Ohio and Indiana, serving just over 100,000 customers opting for choice among energy providers. In 2004, Vectren Source was certified by the Georgia Public Service Commission and has begun initial marketing efforts in the Atlanta Gas Light Company service territory.

Net income generated by Energy Marketing and Services for the year ended December 31, 2004, was $16.6 million compared to $15.3 million in 2003 and $12.1 million in 2002. Throughout the periods presented, gas marketing operations, performed through ProLiance, provided the primary earnings contribution, totaling $15.4 million in 2004 and in 2003 and $14.6 million in 2002. While earnings remained relatively consistent in 2004 compared to 2003, ProLiance experienced increased earnings primarily related to asset optimization from storage activities as a result of significant price volatility. However, those increases were offset by the reserve established for the contingency described below. The 2003 increase over 2002 was principally attributable to increased storage capacity coupled with more volatile gas prices.

Earnings growth has also been impacted by Vectren Source's operations. Vectren Source, a start up operation, operated at a planned loss of $0.4 million, in 2004, as compared to a loss of $1.9 million in 2003 and $2.6 million in 2002. Vectren Source has expanded its customer base and has increased margins per unit of throughput.

Earnings from performance contracting operations, performed through ESG, contributed earnings of $2.8 million in 2004 nearly matching last year's contribution of $3.0 million. Earnings in 2002 were $0.7 million. The $2.3 million increase in 2003 compared to 2002 is due primarily to higher margins and working from a higher construction backlog at the end of 2002 as well as increased ownership as of April 2003.

ProLiance Contingency

In 2002, a lawsuit was filed in the United States District Court for the Northern District of Alabama filed by the City of Huntsville, Alabama d/b/a Huntsville Utilities, Inc. (Huntsville Utilities) against ProLiance. Huntsville Utilities asserted claims based on alleged breach of contract with respect to provision of portfolio services and/or pricing advice, fraud, fraudulent inducement, and other theories, including conversion and violations under Racketeering, Influenced and Corrupt Organizations Act (RICO). These claims related generally to: (1) alleged breach of contract in providing advice and/or administering portfolio arrangements; (2) alleged promises to provide gas at a below-market rate; (3) the creation and repayment of a "winter levelizing program" instituted by ProLiance in conjunction with the Manager of Huntsville's Gas Utility, to allow Huntsville Utilities to pay its gas bills from the winter of 2000-2001 over an extended period of time coupled with the alleged ignorance about the program on the part of Huntsville Utilities' Gas Board and other management, and; (4) the sale of Huntsville Utilities' gas storage supplies to repay the balance owed on the winter levelizing program and the alleged lack of authority of Huntsville Utilities' gas manager to approve those sales.

In early 2005, a jury trial was commenced and on February 10, 2005, the jury returned a verdict largely in favor of Huntsville Utilities and awarded Huntsville Utilities compensatory damages of $8.2 million and punitive damages of $25.0 million. The jury rejected Huntsville Utilities' claim of conversion. The jury also rejected ProLiance's counter claim for payment. The amounts due from Huntsville Utilities were fully reserved by ProLiance in 2003. Huntsville Utilities claims that all or a portion of the compensatory damages may be subject to trebling under applicable Federal statutes. The court may also assess attorney's fees and costs in favor of Huntsville Utilities. If the Court applies trebling and awards attorney fees, the entire award could approach $55 million. Several matters are still pending at the trial court, including efforts by ProLiance to reduce the amount of the verdict. ProLiance will file post judgment motions to reduce and to set aside the verdict. The court may issue its final rulings on the verdict and related motions by April or May. Depending on the outcome, ProLiance would appeal the judgment of the trial court. ProLiance management believes that there are reasonable grounds to set aside or reduce the verdict and reasonable grounds for appeal which offer a basis for reversal of the entire verdict. While it is reasonably possible that a liability has been incurred by ProLiance, it is not possible to predict the ultimate outcome of an appeal of the verdict. ProLiance has recorded a reserve of $3.9 million as of December 31, 2004, reflective of their assessment of the lower end of the range of possible outcomes in the case and inclusive of estimated ongoing litigation costs.

As an equity investor in ProLiance, the Company has reflected its share of the charge, or $1.4 million after tax, in its 2004 results. It is not expected that an unfavorable outcome on appeal will have a material adverse effect on the Company's consolidated financial position or its liquidity, but an unfavorable outcome could be material to the Company's earnings.

Coal Mining

The Coal Mining group mines and sells coal to the Company's utility operations and to third parties through its wholly owned subsidiary Vectren Fuels, Inc. (Fuels). The Coal Mining Group also generates IRS Code Section 29 tax credits relating to the production of coal-based synthetic fuels through its 8.3% ownership interest in Pace Carbon Synfuels, LP (Pace Carbon). Pace Carbon developed, owns, and operates four projects to produce and sell coal-based synthetic fuel (synfuel) utilizing Covol technology. Vectren accounts for its investment in Pace Carbon using the equity method. In addition, Fuels receives synfuel-related fees from synfuel producers unrelated to Pace Carbon for a portion of its coal production.

Coal Mining net income for the year ended December 31, 2004, was $12.5 million, as compared to $13.0 million in 2003, and $11.5 million in 2002. Synfuel-related results, which include earnings from Pace Carbon and synfuel processing fees earned by Fuels, were $12.1 million in 2004, $13.3 million in 2003, and $8.5 million in 2002. The 2004 decrease reflects lower production of synthetic fuel produced by Pace Carbon due to feedstock problems at one of their four plants. The underperforming plant was relocated and began production in January 2005. The 2003 increase is due to greater production of synthetic fuel by Pace Carbon. The production of synthetic fuel generates Section 29 tax credits that are utilized by the Company, reducing income tax expense in those years. Earnings from Mining operations were $0.4 million in 2004 compared to a loss of $0.3 million in 2003 and earnings of $3.0 million in 2002. Increased earnings in 2004 were due primarily to improved production and market pricing which were partially offset by weather conditions and increased commodity costs, such as steel, explosives and diesel fuel. In 2003, mining operations experienced decreased yields due to poor mining conditions and increased mine development cost amortization compared to 2002.

IRS Section 29 Tax Credit Recent Developments

Under Section 29 of the Internal Revenue Code, manufacturers of synthetic fuel such as Pace Carbon receive a tax credit for every ton of synthetic fuel sold. To qualify for the credits, the synthetic fuel must meet three primary conditions: 1) there must be a significant chemical change in the coal feedstock, 2) the product must be sold to an unrelated person, and 3) the production facility must have been placed in service before July 1, 1998.

In past rulings, the Internal Revenue Service (IRS) has concluded that the synthetic fuel produced at the Pace Carbon facilities should qualify for Section 29 tax credits. The IRS issued a private letter ruling with respect to the four projects on November 11, 1997, and subsequently issued an updated private letter ruling on September 23, 2002. As a partner in Pace Carbon, Vectren has reflected
Section 29 tax credits in its consolidated results through December 31, 2004, of approximately $56.2 million. To date, Vectren has been in a position to fully recognize the credits generated.

During June 2001, the IRS began a tax audit of Pace Carbon for the 1998 tax year and later expanded the audit to include tax years 1999, 2000, and 2001. In May 2004, the IRS completed its audit of the 1998 to 2001 tax returns of Pace Carbon requesting only minor modifications to previously filed returns. There were no changes to any of the filed Section 29 tax credit calculations. The Permanent Subcommittee on Investigations of the U.S. Senate's Committee on Governmental Affairs, however, has an ongoing investigation related to Section 29 tax credits.

Vectren believes it is justified in its reliance on the private letter rulings and recent IRS audit results for the Pace Carbon facilities. Therefore, the Company will continue to recognize Section 29 tax credits as they are earned until there is either a change in the tax code or the IRS' interpretation of that tax code.

Further, Section 29 tax credits are only available when the price of oil is less than a base price specified by the tax code, as adjusted for inflation. The Company does not believe that credits realized in 2004 and prior years will be affected by the limitation, but an average annual price in excess of the mid $50 per barrel range, as priced at the wellhead, could limit Section 29 tax credits in 2005 and beyond. In January 2005, the Company executed an insurance arrangement that partially limits the Company's exposure if a limitation on the availability of tax credits were to occur in 2005 and/or 2006 due to oil prices.

Utility Infrastructure Services

Utility Infrastructure Services provides underground construction and repair to gas, water, and telecommunications companies primarily through its investment in Reliant Services, LLC (Reliant) and Reliant's 100% ownership in Miller Pipeline. Reliant is a 50% owned strategic alliance with an affiliate of Cinergy Corp. and is accounted for using the equity method of accounting. Infrastructure's operations achieved annual earnings in 2004 totaling $1.8 million, compared to a loss of $0.9 million in 2003 and $1.2 million in 2002. The $2.7 million improvement in 2004 was primarily driven by better pricing and increases in utility and municipal waste water construction and repair spending during 2004, along with productivity improvements. In the first half of 2003 and throughout all 2002, results were affected by cutbacks of underground construction and repair projects by gas distribution customers. In the second half of 2003, Miller returned to profitability due to an increase in construction and repair projects as utilities began to return to historical expenditure levels.

Broadband and Other Businesses

The Company has an approximate 2% equity interest and a convertible subordinated debt investment in Utilicom Networks, LLC (Utilicom) that if converted bring the Company's ownership interest up to 16%. The Company also has an approximate 19% equity interest in SIGECOM Holdings, Inc., which was formed by Utilicom to hold interests in SIGECOM, LLC (SIGECOM). SIGECOM provides broadband services, such as cable television, high-speed internet, and advanced local and long distance phone services, to over 28,000 customers, averaging over 3 revenue generating units per customer, in the greater Evansville, Indiana. SIGECOM's operations are cash flow positive and have not required any further investment since May 2002.

Other Utilicom-related subsidiaries also owned franchising agreements to provide broadband services to the greater Indianapolis, Indiana and Dayton, Ohio markets. In 2004, the build out of these markets was further evaluated, and the Company concluded that it was unlikely it would make additional investments in those markets. As a result, the Company recorded charges totaling $6.0 million, or $3.6 million after-tax, to write-off investments made in the Indianapolis and Dayton markets and to write down its investment in SIGECOM. The year ended December 31, 2003, also includes a $1.2 million after tax loss resulting from the sale of a small broadband operation located in Indianapolis.

The Other Businesses group includes a variety of wholly owned operations and investments that invest in energy-related opportunities, real estate, and leveraged leases, among other investments. For the year ended December 31, 2004, the Other Businesses Group reported $1.3 million in losses, as compared to earnings of $1.3 million in 2003 and losses of $3.7 million in 2002.

As part of the Company's decision to no longer expand its broadband-related operations, the Company ceased operations of Vectren Communications Services, Inc. (VCS), a municipal broadband consulting business, during the second quarter of 2004. This decision resulted in losses of $2.4 million after tax due primarily to inventory write downs, cessation charges, and other costs. VCS' total loss for 2004 was $2.6 million, as compared to losses of $1.8 million in 2003 and $2.8 million in 2002.

The Haddington Energy Partnerships are equity method investments that invest in energy-related ventures. During 2004, these partnerships sold their investments in SAGO Energy, LP, (SAGO) for cash. The Company recognized its portion of the after tax gain totaling $5.3 million. These earnings were partially offset by Haddington's write-down of Nations Energy Holdings, of which Vectren's portion was $3.5 million after tax. In total, earnings from Haddington for the year ended December 31, 2004, are $2.0 million compared to a loss of $0.6 million in 2003, and break even results in 2002.

The Other Businesses group 2003 results include $3.8 million in after tax gains from the sale of debt collection and supply chain management subsidiaries and the sale of an investment in a company that provides real-time power plant and transmission line status information.

In total, Broadband and Other Businesses reported combined charges of $6.0 million after tax in 2004 to write down its broadband-related investments. Net increases in 2004 from Haddington's results of $2.6 million were comparable to net gains recognized in 2003 from the sale of various subsidiaries and investments.

Impact of Recently Issued Accounting Guidance

SFAS 123 (revised 2004)
In December 2004, the FASB issued Statement 123 (revised 2004), "Share-Based Payments" (SFAS 123R) that will require compensation costs related to share-based payment transactions to be recognized in the financial statements. With limited exceptions, the amount of compensation cost will be measured based on the grant-date fair value of the equity or liability instruments issued. In addition, liability awards will be remeasured each reporting period. Compensation cost will be recognized over the period that an employee provides service in exchange for the award. SFAS 123R replaces FASB Statement No. 123, "Accounting for Stock-Based Compensation" and supersedes APB Opinion No. 25, "Accounting for Stock Issued to Employees." The effective date of SFAS 123R for the Company is July 1, 2005. SFAS 123R provides for multiple transition methods, and the Company is still evaluating potential methods for adoption. The adoption of this standard is not expected to have any material effect on the Company's operating results or financial condition.

EITF 03-01
In March 2004, the EITF issued a consensus on Issue No. 03-01, "The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments" (EITF 03-01). In EITF 03-01, the Task Force developed a basic model for evaluating whether investments within the scope of EITF 03-01, which includes cost method and equity method investments, have other-than-temporary impairment. The basic model includes three steps: 1) determine if there is impairment; 2) if there is impairment, decide whether it is temporary or other than temporary; and
3) if it is other than temporary, recognize it in earnings. EITF 03-01 also requires certain qualitative and quantitative disclosure of material impairments judged to be temporary. The EITF has yet to finalize Steps 2 and 3. Step 1 and the disclosure requirements are currently effective, and the adoption of those portions of the EITF did not have a material effect on the Company.

As noted in the Broadband discussion above, the Company incurred an other-than-temporary impairment charge associated with its cost method investment in SIGECOM, LLC, during 2004. While the Company currently believes that the book value of that investment approximates fair value, further changes in estimated fair value may occur.

Critical Accounting Policies

Management is required to make judgments, assumptions, and estimates that affect the amounts reported in the consolidated financial statements and the related disclosures that conform to accounting principles generally accepted in the United States. Note 2 to the consolidated financial statements describes the significant accounting policies and methods used in the preparation of the consolidated financial statements. Certain estimates used in the financial statements are subjective and use variables that require judgment. These include the estimates to perform goodwill and other asset impairments tests and to determine pension and postretirement benefit obligations. The Company makes other estimates in the course of accounting for unbilled revenue and the effects of regulation that are critical to the Company's financial results but that are less likely to be impacted by near term changes. Other estimates that significantly affect the Company's results, but are not necessarily critical to operations, include depreciating utility and non-utility plant, valuating of derivative contracts, and estimating uncollectible accounts, among others. Actual results could differ from these estimates.

Impairment Review of Investments

The Company has investments in notes receivable, entities accounted for using the cost method of accounting, and entities accounted for using the equity method of accounting. When events occur that may cause one of these investments to be impaired, the Company performs an impairment analysis. An impairment analysis of notes receivable usually involves the comparison of the investment's estimated free cash flows to the stated terms of the note, or for notes that are collateral dependent, a comparison of the collateral's fair value to the carrying amount of the note. An impairment analysis of cost method and equity method investments involves comparison of the investment's estimated fair value to its carrying amount. Fair value is estimated using market comparisons, appraisals, and/or discounted cash flow analyses. Calculating free cash flows and fair value using the above methods is subjective and requires judgment concerning growth assumptions, longevity of cash flows, and discount rates (for fair value calculations).

During 2004, the Company performed an impairment analysis on its Utilicom-related investments. The Company used free cash flow analyses to estimate fair value for the cost method portion of the Utilicom investment and recoverability of the related notes receivable. An impairment charge totaling $6.0 million was recorded as a result of the analysis. A 10% increase in the discount rate assumption utilized to calculate Utilicom's fair value would have resulted in an estimated additional $2 million impairment charge to the cost method investment and no additional impairment charge to the notes receivable.

Impairment tests on other investments were also conducted using appraisals and discounted cash flow models to estimate fair value. No impairment charges resulted from these analyses in 2002 and a $3.9 million write-off of investments in an entity that processes fly ash resulted in 2003. For the other impairment tests performed during 2002, a 10% adverse change in the calculated or appraised fair value of collateral or a 100 basis point adverse change in the discount rate used to estimate fair value would have resulted in an approximate $3 million impairment charge. A 10% adverse change of such factors would not have affected the 2003 write-off.

Goodwill

Pursuant to SFAS No. 142, the Company performs an impairment analysis of its goodwill, almost all of which resides in the Gas Utility Services operating segment, annually, at the beginning of each year, and more frequently if events or circumstances indicate that an impairment loss may have been incurred. Impairment tests are performed at the reporting unit level which the Company has determined to be consistent with its Gas Utility Services operating segment as identified in Note 16 to the consolidated financial statements. An impairment test performed in accordance with SFAS 142 requires that a reporting unit's fair value be estimated. The Company used a discounted cash flow model to estimate the fair value of its Gas Utility Services operating segment, and that estimated fair value was compared to its carrying amount, including goodwill. The estimated fair value was in excess of the carrying amount in 2004, 2003, and 2002 and therefore resulted in no impairment.

Estimating fair value using a discounted cash flow model is subjective and requires significant judgment in applying a discount rate, growth assumptions, company expense allocations, and longevity of cash flows. A 100 basis point increase in the discount rate utilized to calculate the Gas Utility Services segment's fair value also would have resulted in no impairment charge.

Pension and Other Postretirement Obligations

The Company estimates the expected return on plan assets, discount rate, rate of compensation increase, and future health care costs, among other things, and relies on actuarial estimates to assess the future potential liability and funding requirements of the Company's pension and postretirement plans. The Company annually measures its obligations on September 30. The Company used the following weighted average assumptions to develop 2004 periodic benefit cost: a discount rate of 6.0%, an expected return on plan assets of 8.5%, a rate of compensation increase of 3.5%, and a health care cost trend rate of 10% in 2004 declining to 5% in 2009. During 2004, the Company reduced the discount rate by 25 basis points to value 2004 ending pension and postretirement obligations due to a decline in benchmark interest rates. In addition, the Company reduced its 2005 expected return on plan assets 25 basis points from that used to estimate 2004 expense due to lower investment returns and changes in the economic outlook for equity returns. Pension and postretirement periodic cost has increased from approximately $13 million in 2002 to over $16 million in 2004. Preliminary estimates of 2005 periodic cost approximated $18 million. In January 2005, the Company announced the amendment of certain postretirement benefit plans, effective January 1, 2006. The amendment will result in an estimated $3 million annual decrease in periodic cost, a portion of which will be recognized in 2005, reducing those preliminary estimates. Two of the unions that represent bargaining employees at the Company's regulated subsidiaries have advised the Company that it is their position that these changes are not permitted under the existing collective bargaining agreements which govern the relationship between the employees and the affected subsidiaries. With assistance from legal counsel, management has analyzed the unions' position and continues to believe that the Company has reserved the right to amend the affected plans and that changing these benefits for retirees is not a mandatory subject of bargaining. Future changes in health care costs, work force demographics, interest rates, or plan changes could significantly affect the estimated cost of these future benefits.

For the year ended December 31, 2004, a one percentage point adverse change in the assumed health care cost trend rate for the postretirement health care plans would have decreased pre-tax income by approximately $0.6 million and would have increased the postretirement liability by approximately $7.6 million. Management estimates that a 50 basis point reduction in the expected return on plan assets would have increased 2004 periodic benefit cost by approximately $0.8 million.

Unbilled Revenues

To more closely match revenues and expenses, the Company records revenues for all gas and electricity delivered to customers but not billed at the end of the accounting period. The Company uses actual units billed during the month to allocate unbilled units. Those allocated units are multiplied by rates in effect during the month to calculate unbilled revenue at balance sheet dates. While certain estimates are used in the calculation of unbilled revenue, the method these estimates are derived from is not subject to near-term changes.

Regulation

At each reporting date, the Company reviews current regulatory trends in the markets in which it operates. This review involves judgment and is critical in assessing the recoverability of regulatory assets as well as the ability to continue to account for its activities based on the criteria set forth in SFAS No. 71 "Accounting for the Effects of Certain Types of Regulation" (SFAS 71). Based on the Company's current review, it believes its regulatory assets are probable of recovery. If all or part of the Company's operations cease to meet the criteria of SFAS 71, a write-off of related regulatory assets and liabilities could be required. In addition, the Company would be required to determine any impairment to the carrying value of its utility plant and other regulated assets. In the unlikely event of a change in the current regulatory environment, such write-offs and impairment charges could be significant.

Financial Condition

Within Vectren's consolidated group, VUHI funds the short-term and long-term financing needs of the Utility Group operations, and Vectren Capital Corp (Vectren Capital) funds short-term and long-term financing needs of the Nonregulated Group and corporate operations. Vectren Corporation guarantees Vectren Capital's debt, but does not guarantee VUHI's debt. Vectren Capital's long-term and short-term obligations outstanding at December 31, 2004, totaled $113.0 million and $104.0 million, respectively. VUHI's outstanding long-term and short-term borrowing arrangements are jointly and severally guaranteed by Indiana Gas, SIGECO, and VEDO. VUHI's long-term and short-term obligations outstanding at December 31, 2004, totaled $550.0 million and $308.0 million, respectively. Additionally, prior to VUHI's formation, Indiana Gas and SIGECO funded their operations separately, and therefore, have long-term debt outstanding funded solely by their operations.

The Company's common stock dividends are primarily funded by utility operations. Nonregulated operations have demonstrated sustained profitability, and the ability to generate cash flows. These cash flows are primarily reinvested in other nonregulated ventures, but are also used to fund a portion of the Company's dividends, and from time to time may be reinvested in utility operations or used for corporate expenses.

VUHI's and Indiana Gas' credit ratings on outstanding senior unsecured debt at December 31, 2004, are A-/Baa1 as rated by Standard and Poor's Ratings Services (Standard and Poor's) and Moody's Investors Service (Moody's), respectively. SIGECO's credit ratings on outstanding senior unsecured debt are BBB+/Baa1. SIGECO's credit ratings on outstanding secured debt are A-/A3. VUHI's commercial paper has a credit rating of A-2/P-2. Vectren Capital's senior unsecured debt is rated BBB+/Baa2. The ratings of Moody's and Standard and Poor's are categorized as investment grade and are unchanged from December 31, 2003. Moody's current outlook is stable. During January 2005, Standard and Poor's changed its current outlook to stable from negative. A security rating is not a recommendation to buy, sell, or hold securities. The rating is subject to revision or withdrawal at any time, and each rating should be evaluated independently of any other rating. Standard and Poor's and Moody's lowest level investment grade rating is BBB- and Baa3, respectively.

The Company's consolidated equity capitalization objective is 45-55% of permanent capitalization. This objective may have varied, and will vary, depending on particular business opportunities, capital spending requirements, and seasonal factors that affect the Company's operations. The Company's equity component was 51% and 49% of permanent capitalization at December 31, 2004, and 2003, respectively. Permanent capitalization includes long-term debt, including current maturities and debt subject to tender, as well as common shareholders' equity and any outstanding preferred stock.

The Company expects the majority of its capital expenditures, investments, and debt security redemptions to be provided by internally generated funds. However, due to significant capital expenditures and expected growth in nonregulated operations, the Company may require additional permanent financing.

Sources & Uses of Liquidity

Operating Cash Flow

The Company's primary historical source of liquidity to fund working capital requirements has been cash generated from operations. Cash flow from operating activities increased $64.0 million during the year ended December 31, 2004, compared to 2003 primarily as a result of favorable changes in working capital accounts offset by decreased earnings before non-cash charges. The decreased earnings before non-cash charges result principally from lower deferred tax expense due to approximately $31.9 million in alternative minimum taxes recognized in 2004, which has reduced deferred tax expense. Operating cash flow in 2003 decreased $115.2 million compared to 2002. The primary reason for the decrease was the negative effect of higher gas prices on working capital, offset by increased earnings before non-cash charges.

Financing Cash Flow

Although working capital requirements are generally funded by cash flow from operations, the Company uses short-term borrowings to supplement working capital needs when accounts receivable balances are at their highest and gas storage is refilled. Additionally, short-term borrowings are required for capital projects and investments until they are permanently financed.

Cash flow required for financing activities of $18.3 million for the year ended December 31, 2004, includes a net increase of short-term borrowings of $139.5 million and the net retirement of $38.3 million of long-term debt. Cash flow provided by financing activities of $45.8 million for the year ended December 31, 2003, includes the effects of the permanent financing executed during the current year in which approximately $366 million in equity, debt, and hedging net proceeds were received and used to retire higher coupon long-term debt and other short term borrowings. Common stock dividends have increased over the periods presented due to the issuance of new securities and board authorized increases in the dividend rate.

Equity Issuance
In March 2003, the Company filed a registration statement with the Securities and Exchange Commission with respect to a public offering of authorized but previously unissued shares of common stock as well as the senior unsecured notes of VUHI described below. In August 2003, the registration became effective, and an agreement was reached to sell approximately 7.4 million shares to a group of underwriters. The net proceeds totaled $163.2 million and were utilized entirely by VUHI and VUHI's subsidiaries to repay short-term borrowings and to retire long-term debt with higher interest rates.

VUHI Debt Issuance
In July 2003, VUHI issued senior unsecured notes with an aggregate principal amount of $200 million in two $100 million tranches. The first tranche was 10-year notes due August 2013, with an interest rate of 5.25% priced at 99.746% to yield 5.28% to maturity (2013 Notes). The second tranche was 15-year notes due August 2018 with an interest rate of 5.75% priced at 99.177% to yield 5.80% to maturity (2018 Notes).

The notes are guaranteed by the VUHI's three public utilities: SIGECO, Indiana Gas, and VEDO. These guarantees are full and unconditional and joint and several. In addition, they have no sinking fund requirements, and interest payments are due semi-annually. The notes may be called by VUHI, in whole or in part, at any time for an amount equal to accrued and unpaid interest, plus the greater of 100% of the principal amount or the sum of the present values of the remaining scheduled payments of principal and interest, discounted to the redemption date on a semi-annual basis at the Treasury Rate, as defined in the indenture, plus 20 basis points for the 2013 Notes and 25 basis points for the 2018 Notes.

Shortly before these issues, VUHI entered into several treasury locks with a total notional amount of $150.0 million. Upon issuance of the debt, the treasury locks were settled resulting in the receipt of $5.7 million in cash, which was recorded as a regulatory liability pursuant to existing regulatory orders. The value received is being amortized as a reduction of interest expense over the life of the issues.

The net proceeds from the sale of the senior notes and settlement of related hedging arrangements approximated $203 million and were used to repay short-term borrowing and to retire long-term debt with higher interest rates.

Long-Term Debt Put & Call Provisions
Certain long-term debt issues contain put and call provisions that can be exercised on various dates before maturity. Other than those described below related to ratings triggers, the put or call provisions are not triggered by specific events, but are based upon dates stated in the note agreements, such as when notes are re-marketed. During 2004, 2003, and 2002, debt totaling $2.5 million, $0.1 million, and $5.2 million, respectively, was put to the Company. Debt that may be put to the Company within one year is classified as Long-term debt subject to tender in current liabilities.

SIGECO and Indiana Gas Debt Call
During 2004, the Company called $20.0 million of insured quarterly senior unsecured notes outstanding at Indiana Gas. The notes, originally due in 2015, were called at par.

During 2003, the Company called two first mortgage bonds outstanding at SIGECO and two senior unsecured notes outstanding at Indiana Gas. The first SIGECO bond had a principal amount of $45.0 million, an interest rate of 7.60%, was originally due in 2023, and was redeemed at 103.745% of its stated principal amount. The second SIGECO bond had a principal amount of $20.0 million, an interest rate of 7.625%, was originally due in 2025, and was redeemed at 103.763% of the stated principal amount.

The first Indiana Gas note had a remaining principal amount of $21.3 million, an interest rate of 9.375%, was originally due in 2021, and was redeemed at 105.525% of the stated principal amount. The second Indiana Gas note had a principal amount of $13.5 million, an interest rate of 6.75%, was originally due in 2028, and was redeemed at the principal amount.

Pursuant to regulatory authority, the premiums paid to retire these notes totaling $3.6 million were deferred as a regulatory asset.

Other Financing Transactions

During 2004, the Company remarketed two first mortgage bonds outstanding at SIGECO. The remarketing effort converted $32.8 million of outstanding fixed rate debt into variable rate debt where interest rates reset weekly. One bond, due in 2023, had a principal amount of $22.8 million and an interest rate of 6%. The other bond, due in 2015, had a principal amount of $10.0 million and an interest rate of 4.3%. These remarketing efforts resulted in the extinguishment and reissuance of debt at generally the same par value.

At December 31, 2002, the Company had $26.6 million of adjustable rate senior unsecured bonds which could, at the election of the bondholder, be tendered to the Company when interest rates are reset. Such bonds were classified as Long-term debt subject to tender. During 2003, the Company re-marketed $4.6 million of the bonds through 2020 at a 4.5% fixed interest rate and remarketed $22.0 million of the bonds through 2030 at a 5.0% fixed interest rate.

Additionally, during 2003, the Company re-marketed $22.5 million of first mortgage bonds subject to interest rate exposure on a long term basis. The $22.5 million of mortgage bonds were remarketed through 2024 at a 4.65% fixed interest rate.

Other Company debt totaling $15.0 million in 2004, $18.5 million in 2003, and $6.5 million in 2002 was retired as scheduled.

Investing Cash Flow

Cash flow required for investing activities was $265.1 million in 2004, $232.7 million in 2003, and $234.6 million in 2002. Capital expenditures are the primary component of investing activities. Capital expenditures were $277.9 million in 2004 compared to $236.2 million in 2003 and $218.7 million in 2002. The increases are primarily driven by expenditures for environmental compliance. In 2004 and 2003, the increase in capital expenditures was offset by collections of notes receivable and distributions by unconsolidated affiliates.

Available Sources of Liquidity

At December, 31, 2004, the Company has $615 million of short-term borrowing capacity, including $355 million for the Utility Group and $260 million for the wholly owned Nonregulated Group and corporate operations, of which approximately $47 million is available for the Utility Group operations and approximately $156 million is available for the wholly owned Nonregulated Group and corporate operations.

VUHI's short-term credit facility was renewed on June 24, 2004 at $350 million, a slight increase from the previous year's renewal level of $346 million. Instead of the traditional 364-day facility, the facility was renewed for a 5-year period ending June 2009.

Vectren Capital renewed its existing $200 million credit facility early, increased the committed capacity, and obtained a multi-year commitment on that facility as well, rather than the traditional 364-day facility. On September 30, 2004 the new Vectren Capital credit facility was closed at the $255 million level for a 5-year period ending September 2009.

The Company periodically issues new shares to satisfy dividend reinvestment plan and stock option plan requirements. During 2004 and 2003, these new issuances added additional liquidity of $4.5 million and $7.1 million, respectively.

Off Balance Sheet Arrangements

Ratings Triggers
At December 31, 2004, $113.0 million of Vectren Capital's senior unsecured notes were subject to cross-default and ratings trigger provisions that would provide that the full balance outstanding is subject to prepayment if the ratings of Indiana Gas or SIGECO declined to BBB/Baa2. In addition, accrued interest and a make whole amount based on the discounted value of the remaining payments due on the notes would also become payable. The credit rating of Indiana Gas' senior unsecured debt and SIGECO's secured debt remains one level and two levels, respectively, above the ratings trigger.

Guarantees and Letters of Credit
In the normal course of business, Vectren issues guarantees to third parties on behalf of its consolidated subsidiaries and unconsolidated affiliates. Such guarantees allow those subsidiaries and affiliates to execute transactions on more favorable terms than the subsidiary or affiliate could obtain without such a guarantee. Guarantees may include posted letters of credit, leasing guarantees, and performance guarantees. As of December 31, 2004, guarantees issued and outstanding on behalf of unconsolidated affiliates approximated $5 million. In addition, the Company has also issued a guarantee approximating $4 million related to the residual value of an operating lease that expires in 2006. Through December 31, 2004, the Company has not been called upon to satisfy any obligations pursuant to its guarantees.

Pension and Postretirement Funding Obligations

The Company believes making contributions to its qualified pension plans in the coming years will be necessary. Management currently estimates that the qualified pension plans will require Company contributions in the range of $5 million to $10 million in both 2005 and 2006. During 2004, $7.7 million in contributions were made.

ITEM 7A. QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK

The Company is exposed to various business risks associated with commodity prices, interest rates, and counter-party credit. These financial exposures are monitored and managed by the Company as an integral part of its overall risk management program. The Company's risk management program includes, among other things, the use of derivatives. The Company also executes derivative contracts in the normal course of operations while buying and selling commodities to be used in operations and optimizing its generation assets.

The Company has in place a risk management committee that consists of senior management as well as financial and operational management. The committee is actively involved in identifying risks as well as reviewing and authorizing risk mitigation strategies.

Commodity Price Risk

The Company's regulated operations have limited exposure to commodity price risk for purchases and sales of natural gas and electricity for retail customers due to current Indiana and Ohio regulations, which subject to compliance with those regulations, allow for recovery of the cost of such purchases through natural gas and fuel cost adjustment mechanisms.

Electric sales and purchases in the wholesale power market and other commodity-related operations are exposed to commodity price risk associated with fluctuating commodity prices including electricity, natural gas, and coal. Other commodity-related operations include regulated sales of electricity to certain municipalities and large industrial customers and nonregulated retail gas marketing and coal mining operations. Open positions in terms of price, volume, and specified delivery points may occur and are managed using methods described below with frequent management reporting.

The Company's wholesale power marketing activities include asset optimization strategies that manage the utilization of available electric generating capacity. Execution of asset optimization strategies require entering into energy contracts that commit the Company to purchase and sell electricity in the future. Commodity price risk results from forward positions that commit the Company to deliver electricity. The Company mitigates price risk exposure with planned unutilized generation capability and offsetting forward purchase contracts. The Company accounts for asset optimization contracts that are derivatives at fair value with the offset marked to market through earnings.

The Company's other commodity-related operations involve the purchase and sale of commodities, including electricity, natural gas, and coal to meet customer demands and operational needs. These operations also enter into forward and option contracts that commit the Company to purchase and sell commodities in the future. Price risk from forward positions obligating the Company to deliver commodities is mitigated using stored inventory, generating capability, and offsetting forward purchase contracts. Price risk also results from forward contracts obligating the Company to purchase commodities to fulfill forecasted nonregulated sales of natural gas and coal that may, or may not, occur. With the exception of a small portion of contracts that are derivatives that qualify as hedges of forecasted transactions under SFAS 133, these contracts are expected to be settled by physical receipt or delivery of the commodity.

Nonregulated gas retail operations will from time-to-time purchase weather derivatives to mitigate extreme weather affecting unregulated retail gas sales, and the Company may purchase other tailored products that mitigate unique risks involving emission allowances and the effect oil prices may have on the availability of Section 29 tax credits.

Market risk resulting from commodity contracts is measured by management using the potential impact on pre-tax earnings caused by the effect a 10% adverse change in forward commodity prices might have on market sensitive derivative positions outstanding on specific dates. For the years ended December 31, 2004, and 2003, a 10% adverse change in forward commodity prices would have decreased earnings by $0.7 million and $3.0 million, respectively, based upon open positions existing on the last day of those years.

Commodity Price Risk from Unconsolidated Affiliate

ProLiance, a nonregulated energy marketing affiliate, engages in energy hedging activities to manage pricing decisions, minimize the risk of price volatility, and minimize price risk exposure in the energy markets. ProLiance's market exposure arises from storage inventory, imbalances, and fixed-price forward purchase and sale contracts, which are entered into to support its operating activities. Currently, ProLiance buys and sells physical commodities and utilizes financial instruments to hedge its market exposure. However, net open positions in terms of price, volume and specified delivery point do occur. ProLiance manages open positions with policies which limit its exposure to market risk and require reporting potential financial exposure to its management and its members.

Interest Rate Risk

The Company is exposed to interest rate risk associated with its borrowing arrangements. Its risk management program seeks to reduce the potentially adverse effects that market volatility may have on interest expense. The Company manages this risk by allowing 20% and 30% of its total debt to be exposed to short-term interest rate volatility. However, there are times when this targeted range of interest rate exposure may not be attained. To manage this exposure, the Company may use derivative financial instruments. At December 31, 2004, such debt obligations, as affected by designated interest rate swaps and seasonal increases in short-term debt outstanding, represented 34% of the Company's total debt portfolio.

Market risk is estimated as the potential impact resulting from fluctuations in interest rates on adjustable rate borrowing arrangements exposed to short-term interest rate volatility. During 2004 and 2003, the weighted average combined borrowings under these arrangements were $276.4 million and $316.1 million, respectively. At December 31, 2004, and 2003, combined borrowings under these arrangements were $500.2 million and $328.3 million, respectively. Based upon average borrowing rates under these facilities during the years ended December 31, 2004 and 2003, an increase of 100 basis points (one percentage point) in the rates would have increased interest expense by $2.8 million and $3.2 million, respectively.

Other Risks

By using forward purchase contracts and derivative financial instruments to manage risk, the Company exposes itself to counter-party credit risk and market risk. The Company manages exposure to counter-party credit risk by entering into contracts with companies that can be reasonably expected to fully perform under the terms of the contract. Counter-party credit risk is monitored regularly and positions are adjusted appropriately to manage risk. Further, tools such as netting arrangements and requests for collateral are also used to manage credit risk. Market risk is the adverse effect on the value of a financial instrument that results from a change in commodity prices or interest rates. The Company attempts to manage exposure to market risk associated with commodity contracts and interest rates by establishing parameters and monitoring those parameters that limit the types and degree of market risk that may be undertaken.

The Company's customer receivables from gas and electric sales and gas transportation services are primarily derived from a diversified base of residential, commercial, and industrial customers located in Indiana and west central Ohio. The Company manages credit risk associated with its receivables by continually reviewing creditworthiness and requests cash deposits or refunds cash deposits based on that review. Credit risk associated with certain investments is also managed by a review of creditworthiness and receipt of collateral.

Although the Company's regulated operations are exposed to limited commodity price risk, volatile natural gas prices can result in higher working capital requirements; increased expenses including unrecoverable interest costs, uncollectible accounts expense, and unaccounted for gas; and some level of price sensitive reduction in volumes sold. The Company mitigates these risks by executing derivative contracts that manage the price of forecasted natural gas purchases. These contracts are subject to regulation, which allows for reasonable and prudent hedging costs to be recovered through rates. When regulation is involved, SFAS 71 controls when the offset to mark-to-market accounting is recognized in earnings.


ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

MANAGEMENT'S RESPONSBILITY FOR THE FINANCIAL STATEMENTS

Vectren Corporation's management is responsible for establishing and maintaining adequate internal controls over financial reporting. Those control procedures underlie the preparation of the consolidated balance sheets, statements of income, cash flows, and common shareholders' equity, and related footnotes contained herein.

These consolidated financial statements were prepared in conformity with accounting principles generally accepted in the United States and follow accounting policies and principles applicable to regulated public utilities. The integrity and objectivity of these consolidated financial statements, including required estimates and judgments, is the responsibility of management.

These consolidated financial statements are also subject to an evaluation of internal control over financial reporting conducted under the supervision and with the participation of management, including the Chief Executive Officer and Chief Financial Officer. Based on that evaluation, conducted under the framework in Internal Control -- Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, the Company concluded that its internal control over financial reporting was effective as of December 31, 2004. Management certified this fact in its Sarbanes Oxley Section 302 certifications, which are attached as exhibits to this 2004 Form 10-K.


REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of Vectren Corporation:

We have audited the accompanying consolidated balance sheets of Vectren Corporation and subsidiaries (the "Company") as of December 31, 2004 and 2003, and the related consolidated statements of income, common shareholders' equity, and cash flows for each of the three years in the period ended December 31, 2004. Our audits also included the financial statement schedule listed in the Index at Item 15. We also have audited management's assessment, included in the accompanying Management's Report on Internal Control over Financial Reporting, included at Item 9A, that the Company maintained effective internal control over financial reporting as of December 31, 2004, based on criteria established in Internal Control--Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on these financial statements and financial statement schedule, an opinion on management's assessment, and an opinion on the effectiveness of the Company's internal control over financial reporting based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (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 and whether effective internal control over financial reporting was maintained in all material respects. Our audit of financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, evaluating management's assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2004 and 2003, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2004, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, present fairly, in all material respects, the information set forth therein. Also, in our opinion, management's assessment that the Company maintained effective internal control over financial reporting as of December 31, 2004, is fairly stated, in all material respects, based on the criteria established in Internal Control--Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Furthermore, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2004, based on the criteria established in Internal Control--Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

VECTREN CORPORATION AND SUBSIDIARY COMPANIES

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Nature of Operations

Vectren Corporation (the Company or Vectren), an Indiana corporation, is an energy and applied technology holding company headquartered in Evansville, Indiana. The Company's wholly owned subsidiary, Vectren Utility Holdings, Inc. (VUHI), serves as the intermediate holding company for three operating public utilities: Indiana Gas Company, Inc. (Indiana Gas), Southern Indiana Gas and Electric Company (SIGECO), and the Ohio operations. VUHI also has other assets that provide information technology and other services to the three utilities. VUHI's consolidated operations are collectively referred to as the Utility Group. Both Vectren and VUHI are exempt from registration pursuant to Section
3(a) (1) and 3(c) of the Public Utility Holding Company Act of 1935.

Indiana Gas provides energy delivery services to approximately 555,000 natural gas customers located in central and southern Indiana. SIGECO provides energy delivery services to approximately 136 ,000 electric customers and approximately 110,000 gas customers located near Evansville in southwestern Indiana. SIGECO also owns and operates electric generation to serve its electric customers and optimizes those assets in the wholesale power market. Indiana Gas and SIGECO generally do business as Vectren Energy Delivery of Indiana. The Ohio operations provide energy delivery services to approximately 315,000 natural gas customers located near Dayton in west central Ohio. The Ohio operations are owned as a tenancy in common by Vectren Energy Delivery of Ohio, Inc. (VEDO), a wholly owned subsidiary, (53% ownership) and Indiana Gas (47% ownership). The Ohio operations generally do business as Vectren Energy Delivery of Ohio.

The Company is also involved in nonregulated activities in four primary business areas: Energy Marketing and Services, Coal Mining, Utility Infrastructure Services, and Broadband. Energy Marketing and Services markets natural gas and provides energy management services, including energy performance contracting services. Coal Mining mines and sells coal and generates IRS Code Section 29 tax credits relating to the production of coal-based synthetic fuels. Utility Infrastructure Services provides underground construction and repair, facilities locating, and meter reading services. Broadband has investments in broadband communication services such as analog and digital cable television, high-speed internet and data services, and advanced local and long distance phone services. In addition, there are other businesses that invest in energy-related opportunities, real estate, and leveraged leases, among other activities. These operations are collectively referred to as the Nonregulated Group. The Nonregulated Group supports the Company's regulated utilities pursuant to service contracts by providing natural gas supply services, coal, utility infrastructure services, and other services.

2. Summary of Significant Accounting Policies

A. Principles of Consolidation
The consolidated financial statements include the accounts of the Company and its wholly owned and majority owned subsidiaries, after elimination of significant intercompany transactions.

In January 2003, the FASB issued Interpretation 46, "Consolidation of Variable Interest Entities" (FIN 46) and in December 2003, the FASB codified modifications and other decisions previously issued through certain FASB Staff Positions related to FIN 46 into one document that was issued as a revision to the original Interpretation (FIN 46R). FIN 46R addresses consolidation by business enterprises of variable interest entities. The Company adopted the provisions within FIN 46R during 2004. The Company has investments in partnership-like structures as a limited partner or as a subordinated lender. The activities of these entities are to purchase or construct as well as operate multifamily housing and office properties. The Company's exposure to loss is limited to its investment which as of December 31, 2004, and 2003, totaled $16.2 million and $17.1 million, respectively, of Investments in unconsolidated affiliates, and $16.7 million and $20.9 million, respectively, of Other investments. The Company is also the equity owner in three leveraged leases where its exposure to loss is limited to its net investment, which as of December 31, 2004, and 2003, totaled $7.0 million and $6.0 million, respectively. The Company did not consolidate any of these entities upon adoption of FIN 46R.

   Non-utility property - net                  $ 229.2              $ 222.3
============================================================================

The depreciation of non-utility property is charged against income over its estimated useful life (ranging from 5 to 40 years), using the straight-line method of depreciation or units-of-production method of amortization. Repairs and maintenance, which are not considered improvements and do not extend the useful life of the non-utility property, are charged to expense as incurred. When non-utility property is retired, or otherwise disposed of, the asset and accumulated depreciation are removed, and the resulting gain or loss is reflected in income. Non-utility property is presented net of accumulated depreciation and amortization totaling $111.1 million and $84.5 million as of December 31, 2004, and 2003, respectively. For the years ended December 31, 2004, 2003, and 2002, the Company capitalized interest totaling $1.4 million, $0.5 million, and $0.4 million, respectively, on non-utility plant construction projects.

F. Impairment Review of Long-Lived Assets Long-lived assets are reviewed as facts and circumstances indicate that the carrying amount may be impaired. This review is performed in accordance with SFAS No. 144 "Accounting for the Impairment or Disposal of Long-Lived Assets" (SFAS 144), which the Company adopted on January 1, 2002. SFAS 144 establishes one accounting model for all impaired long-lived assets and long-lived assets to be disposed of by sale or otherwise. SFAS 144 requires the evaluation for impairment involve the comparison of an asset's carrying value to the estimated future cash flows the asset is expected to generate over its remaining life. If this evaluation were to conclude that the carrying value of the asset is impaired, an impairment charge would be recorded based on the difference between the asset's carrying amount and its fair value (less costs to sell for assets to be disposed of by sale) as a charge to operations or discontinued operations.

G. Goodwill
Goodwill arising from business combinations is accounted for in accordance with SFAS No. 142, "Goodwill and Other Intangible Assets" (SFAS 142). The Company adopted SFAS 142 on January 1, 2002. SFAS 142 requires a portion of goodwill be charged to expense only when it is impaired. The Company tests its goodwill for impairment at a reporting unit level at least annually and that test is performed at the beginning of each year. Impairment reviews consist of a comparison of the fair value of a reporting unit to its carrying amount. If the fair value of a reporting unit is less than its carrying amount, an impairment loss is recognized in operations. Through December 31, 2004, no goodwill impairments have been recorded. Approximately $205 million of the Company's goodwill is included in the Gas Utility Services operating segment. The remaining $2.1 million is attributable to the Nonregulated Group.

H. Regulation
Retail public utility operations affecting Indiana customers are subject to regulation by the IURC, and retail public utility operations affecting Ohio customers are subject to regulation by the PUCO.

SFAS 71
The Company's accounting policies give recognition to the rate-making and accounting practices of these agencies and to accounting principles generally accepted in the United States, including the provisions of SFAS 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 rate-making process. Regulatory liabilities represent probable expenditures by the Company for removal costs or future reductions in revenues associated with amounts that are to be credited to customers through the rate-making process.

The Company assesses the recoverability of costs recognized as regulatory assets and the ability to continue to account for its activities based on the criteria set forth in SFAS 71. Based on current regulation, the Company believes such accounting is appropriate. If all or part of the Company's operations cease to meet the criteria of SFAS 71, a write-off of related regulatory assets and liabilities could be required. In addition, the Company would be required to determine any impairment to the carrying value of its utility plant and other regulated assets. Regulatory assets consist of the following:

Of the $30.9 million currently being recovered through base rates charged to customers, $29.7 million is earning a return. The weighted average recovery period of regulatory assets currently being recovered is 13.9 years. The Company has rate orders for all deferred costs not yet in rates and therefore believes that future recovery is probable.


Regulatory liabilities consist of the following:

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

Cost of Removal and SFAS 143
The Company collects an estimated cost of removal of its utility plant through depreciation rates established by regulatory proceedings. The Company records amounts expensed in advance of payments as a regulatory liability because the liability does not meet the threshold of a legal asset retirement obligation (ARO) as defined by SFAS No. 143, "Accounting for Asset Retirement Obligations" (SFAS 143). SFAS 143 requires entities to record the fair value of a liability for a legal ARO in the period in which it is incurred. When the liability is initially recorded, the entity capitalizes a cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, an entity either settles the obligation for its recorded amount or incurs a gain or loss. To the extent regulation is involved, such gain or loss may be deferred. The Company adopted this statement on January 1, 2003. The adoption was not material to the Company's results of operations.

Refundable or Recoverable Gas Costs, Fuel for Electric Production & Purchased Power
All metered gas rates contain a gas cost adjustment clause that allows the Company to charge for changes in the cost of purchased gas. Metered electric rates contain a fuel adjustment clause that allows for adjustment in charges for electric energy to reflect changes in the cost of fuel. The net energy cost of purchased power, subject to an agreed upon benchmark, is also recovered through regulatory proceedings. The Company records any under-or-over-recovery resulting from gas and fuel adjustment clauses each month in revenues. A corresponding asset or liability is recorded until the under-or-over-recovery is billed or refunded to utility customers. The cost of gas sold is charged to operating expense as delivered to customers, and the cost of fuel for electric generation is charged to operating expense when consumed.

I. Comprehensive Income
Comprehensive income is a measure of all changes in equity that result from the non-shareholder transactions. This information is reported in the Consolidated Statements of Common Shareholders' Equity. A summary of the after tax components of and changes in Accumulated other comprehensive income for the past three years follows:

Accumulated other comprehensive income arising from unconsolidated affiliates is the Company's portion of ProLiance Energy, LLC's and Reliant Services, LLC's accumulated comprehensive income related to use of cash flow hedges, including commodity contracts and interest rate swaps, and the Company's portion of Haddington Energy Partners, LP's accumulated comprehensive income related to unrealized gains and losses on marketable securities. (See Note 3 for more information on unconsolidated affiliates.)

J. Revenues
Revenues are recorded as products and services are delivered to customers. To more closely match revenues and expenses, the Company records revenues for all gas and electricity delivered to customers but not billed at the end of the accounting period.

K. Excise and Utility Receipts Taxes
Excise taxes and a portion of utility receipts taxes are included in rates charged to customers. Accordingly, the Company records these taxes received as a component of operating revenues, which totaled $38.3 million in 2004, $37.1 million in 2003, and $32.4 million in 2002. Excise and utility receipts taxes paid are recorded as a component of Taxes other than income taxes.

L. Other Significant Policies
Included elsewhere in these Notes are significant accounting policies related to investments in unconsolidated affiliates (Note 3), income taxes (Note 5), earnings per share (Note 9), and derivatives (Note 15).

As more fully described in Note 10, the Company applies the intrinsic method prescribed in APB Opinion 25, "Accounting for Stock Issued to Employees" (APB 25) and related interpretations when measuring compensation expense for its share-based compensation plans. The exercise price of stock options awarded under the Company's stock option plans is equal to the fair market value of the underlying common stock on the date of grant. Accordingly, no compensation expense has been recognized related to stock option plans. The Company also maintains restricted stock and phantom stock plans for executives, employees, and non-employee directors that result in share-based compensation expense recognized in reported net income consistent with expense that would have been recognized if the Company used the fair value based method prescribed in SFAS No. 123 "Accounting for Stock-Based Compensation" (SFAS 123). Following is the effect on net income and earnings per share as if the fair value based method prescribed in SFAS 123 had been applied to all of the Company's share-based compensation plans:

                                                              Year Ended December 31,

SFAS 123 (revised 2004)
In December 2004, the FASB issued Statement 123 (revised 2004), "Share-Based Payments" (SFAS 123R) that will require compensation costs related to all share-based payment transactions to be recognized in the financial statements. With limited exceptions, the amount of compensation cost will be measured based on the grant-date fair value of the equity or liability instruments issued. Compensation cost will be recognized over the period that an employee provides service in exchange for the award. SFAS 123R replaces SFAS 123 and supersedes APB 25. The effective date of SFAS 123R for Vectren is July 1, 2005. SFAS 123R provides for multiple transition methods, and the Company is still evaluating potential methods for adoption. The adoption of this standard is not expected to have a material effect on the Company's operating results or financial condition.

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

3. Investments in Unconsolidated Affiliates

Investments in unconsolidated affiliates where the Company has significant influence are accounted for using the equity method of accounting. The Company's share of net income or loss from these investments is recorded in Equity in earnings of unconsolidated affiliates. Dividends are recorded as a reduction of the carrying value of the investment when received. Investments in unconsolidated affiliates where the Company does not have significant influence are accounted for using the cost method of accounting less write-downs for declines in value judged to be other than temporary. Dividends are recorded as Other - net when received.

Investments in unconsolidated affiliates consist of the following:

ProLiance Energy, LLC
ProLiance Energy, LLC (ProLiance), a nonregulated energy marketing affiliate of Vectren and Citizens Gas and Coke Utility (Citizens Gas), provides services to a broad range of municipalities, utilities, industrial operations, schools, and healthcare institutions located throughout the Midwest and Southeast United States. ProLiance's primary customers include Vectren's utilities and nonregulated gas supply operations as well as Citizens Gas. ProLiance's primary businesses include gas marketing, gas portfolio optimization, and other portfolio and energy management services. The Company, including its retail gas supply operations, contracted for all natural gas purchases through ProLiance in 2004. Pre-tax income of $25.9 million, $25.9 million, and $19.1 million was recognized as ProLiance's contribution to earnings for the years ended December 31, 2004, 2003, and 2002, respectively.

Integration of SIGCORP Energy Services, LLC and ProLiance Energy, LLC In June 2002, the integration of Vectren's wholly owned gas marketing subsidiary, SIGCORP Energy Services, LLC (SES), with ProLiance was completed. SES provided natural gas and related services to SIGECO and others prior to the integration. In exchange for the contribution of SES' net assets totaling $19.2 million, including cash of $2.0 million, Vectren's allocable share of ProLiance's profits and losses increased to 61%, consistent with Vectren's new ownership percentage. Governance and voting rights remain at 50% for each member; and therefore, Vectren continues to account for its investment in ProLiance using the equity method of accounting.

Prior to June 1, 2002, SES' operating results were consolidated. Subsequent to June 1, 2002, SES' operating results, now part of ProLiance, are reflected in Equity in earnings of unconsolidated affiliates. The transfer of net assets was accounted for at book value consistent with joint venture accounting and did not result in any gain or loss. Additionally, the non-cash component of the transfer totaling $17.2 million is excluded from the Consolidated Statement of Cash Flows.

Transactions with ProLiance
Purchases from ProLiance for resale and for injections into storage for the years ended December 31, 2004, 2003, and 2002, totaled $875.9 million, $797.7 million, and $544.1 million, respectively. Amounts owed to ProLiance at December 31, 2004, and 2003, for those purchases were $108.2 million and $86.0 million, respectively, and are included in Accounts payable to affiliated companies in the Consolidated Balance Sheets. Amounts charged by ProLiance for gas supply services are established by supply agreements with each utility. As part of a settlement agreement approved by the IURC during July 2002, the gas supply agreements with Indiana Gas and SIGECO, were approved and extended through March 31, 2007. The utilities may decide to conduct a "request for proposal" (RFP) for a new supply administrator, or they may decide to make an alternative proposal for procurement of gas supply. That decision will be made by December 2005. To the extent an RFP is conducted, ProLiance has the opportunity, if it so elects, to participate in the RFP process for service to the utilities after March 31, 2007.

Summarized Financial Information
For the year ended December 31, 2004, ProLiance's revenues, margin, operating income, and net income were (in millions) $2,573.8, $74.0, $43.2, and $42.6, respectively. For the year ended December 31, 2003, ProLiance's revenues, margin, operating income, and net income were (in millions) $2,269.7, $71.5, $43.3, and $42.5, respectively. For the year ended December 31, 2002, revenues, margin, operating income, and net income were (in millions) $1,534.5, $61.1, $36.5, and $37.4, respectively. As of December 31, 2004, current assets, noncurrent assets, current liabilities, and noncurrent liabilities were (in millions) $595.6, $0.4, $462.2, and $6.6, respectively. As of December 31, 2003, current assets, noncurrent assets, current liabilities, and noncurrent liabilities were (in millions) $467.7, $22.2, $346.0, and $7.8, respectively.

ProLiance Contingency
In 2002, a lawsuit was filed in the United States District Court for the Northern District of Alabama filed by the City of Huntsville, Alabama d/b/a Huntsville Utilities, Inc. (Huntsville Utilities) against ProLiance. Huntsville Utilities asserted claims based on alleged breach of contract with respect to provision of portfolio services and/or pricing advice, fraud, fraudulent inducement, and other theories, including conversion and violations under Racketeering, Influenced and Corrupt Organizations Act (RICO). These claims related generally to: (1) alleged breach of contract in providing advice and/or administering portfolio arrangements; (2) alleged promises to provide gas at a below-market rate; (3) the creation and repayment of a "winter levelizing program" instituted by ProLiance in conjunction with the Manager of Huntsville's Gas Utility, to allow Huntsville Utilities to pay its gas bills from the winter of 2000-2001 over an extended period of time coupled with the alleged ignorance about the program on the part of Huntsville Utilities' Gas Board and other management, and; (4) the sale of Huntsville Utilities' gas storage supplies to repay the balance owed on the winter levelizing program and the alleged lack of authority of Huntsville Utilities' gas manager to approve those sales.

In early 2005, a jury trial was commenced and on February 10, 2005, the jury returned a verdict largely in favor of Huntsville Utilities and awarded Huntsville Utilities compensatory damages of $8.2 million and punitive damages of $25.0 million. The jury rejected Huntsville Utilities' claim of conversion. The jury also rejected ProLiance's counter claim for payment. The amounts due from Huntsville Utilities were fully reserved by ProLiance in 2003. Huntsville Utilities claims that all or a portion of the compensatory damages may be subject to trebling under applicable Federal statutes. The court may also assess attorney's fees and costs in favor of Huntsville Utilities. If the Court applies trebling and awards attorney fees, the entire award could approach $55 million. Several matters are still pending at the trial court, including efforts by ProLiance to reduce the amount of the verdict. ProLiance will file post judgment motions to reduce and to set aside the verdict. The court may issue its final rulings on the verdict and related motions by April or May. Depending on the outcome, ProLiance would appeal the judgment of the trial court. ProLiance management believes that there are reasonable grounds to set aside or reduce the verdict and reasonable grounds for appeal which offer a basis for reversal of the entire verdict. While it is reasonably possible that a liability has been incurred by ProLiance, it is not possible to predict the ultimate outcome of an appeal of the verdict. ProLiance has recorded a reserve of $3.9 million as of December 31, 2004, reflective of their assessment of the lower end of the range of possible outcomes in the case and inclusive of estimated ongoing litigation costs.

As an equity investor in ProLiance, the Company has reflected its share of the charge, or $1.4 million after tax, in its 2004 results. It is not expected that an unfavorable outcome on appeal will have a material adverse effect on the Company's consolidated financial position or its liquidity, but an unfavorable outcome could be material to the Company's earnings.

Haddington Energy Partnerships
The Company has an approximate 40% ownership interest in Haddington Energy Partners, LP (Haddington I). Haddington I raised $27.0 million to invest in energy projects. In July 2000, the Company made a commitment to fund an additional $20.0 million in Haddington Energy Partners II, LP (Haddington II), which raised a total of $47.0 million in firm commitments. Haddington II provides additional capital for Haddington I portfolio companies and made investments in new areas, such as distributed generation, power backup, quality devices, and other emerging technologies. At December 31, 2004, $5.0 million of the additional $20.0 million commitment remains. The Company has an approximate 40% ownership interest in Haddington II. Both Haddington ventures are investment companies accounted for using the equity method of accounting. For the year ended December 31, 2004, the partnerships' contribution to the Company's pre-tax earnings was $4.5 million. In 2003 and 2002, the earnings contribution was not significant.

The following is summarized financial information as to the assets, liabilities, and results of operations of the Haddington Partnerships. For the year ended December 31, 2004, revenues, operating income, and net income were (in millions) $3.3, $2.5, and $9.6, respectively. For the year ended December 31, 2003, revenues, operating income, and net income were (in millions) $0.6, ($0.3), and ($0.3), respectively. For the year ended December 31, 2002, revenues, operating income, and net income were (in millions) zero, ($0.9), and ($0.9), respectively. As of December 31, 2004, investments, other assets, and liabilities were (in millions) $50.7, $0.2, and zero, respectively. As of December 31, 2003, investments, other assets, and liabilities were (in millions) $64.4, $1.0, and zero, respectively.

Pace Carbon Synfuels, LP
Pace Carbon Synfuels, LP (Pace Carbon) is a Delaware limited partnership formed to develop, own, and operate four projects to produce and sell coal-based synthetic fuel (synfuel) utilizing Covol technology. The Company has an 8.3% interest in Pace Carbon which is accounted for using the equity method of accounting. Additional investments in Pace Carbon will be made to the extent Pace Carbon generates federal tax credits, with any such additional investments to be funded by these credits. The investment in Pace Carbon resulted in losses reflected in Equity in earnings of unconsolidated affiliates totaling $12.0 million in 2004, $11.4 million in 2003, and $6.8 million in 2002. The production of synthetic fuel generates IRS Code Section 29 tax credits that are reflected in Income taxes. Net income, including the losses, tax benefits, and tax credits, generated from the investment in Pace Carbon totaled $9.0 million in 2004, $10.3 million in 2003, and $6.0 million in 2002.

The following is summarized financial information as to the assets, liabilities, and results of operations of Pace Carbon. For the year ended December 31, 2004, revenues, margin, operating loss, and net loss were (in millions) $243.0, ($99.8), ($128.6), and ($141.1), respectively. For the year ended December 31, 2003, revenues, margin, operating loss, and net loss were (in millions) $254.2, ($90.7), ($121.3), and ($134.4), respectively. For the year ended December 31, 2002, revenues, margin, operating loss, and net loss were (in millions) $125.6, ($53.1), ($72.6), and ($73.4), respectively. As of December 31, 2004, current assets, noncurrent assets, current liabilities, and noncurrent liabilities were (in millions) $44.1, $57.0, $25.3, and $19.8, respectively. As of December 31, 2003, current assets, noncurrent assets, current liabilities, and noncurrent liabilities were (in millions) $37.0, $105.2, $25.9, and $58.4, respectively.

IRS Section 29 Tax Credit Recent Developments Under Section 29 of the Internal Revenue Code, manufacturers of synthetic fuel such as Pace Carbon receive a tax credit for every ton of synthetic fuel sold. To qualify for the credits, the synthetic fuel must meet three primary conditions: 1) there must be a significant chemical change in the coal feedstock, 2) the product must be sold to an unrelated person, and 3) the production facility must have been placed in service before July 1, 1998.

In past rulings, the Internal Revenue Service (IRS) has concluded that the synthetic fuel produced at the Pace Carbon facilities should qualify for Section 29 tax credits. The IRS issued a private letter ruling with respect to the four projects on November 11, 1997, and subsequently issued an updated private letter ruling on September 23, 2002. As a partner in Pace Carbon, Vectren has reflected
Section 29 tax credits in its consolidated results through December 31, 2004, of approximately $56.2 million. To date, Vectren has been in a position to fully recognize the credits generated.

During June 2001, the IRS began a tax audit of Pace Carbon for the 1998 tax year and later expanded the audit to include tax years 1999, 2000, and 2001. In May 2004, the IRS completed its audit of the 1998 to 2001 tax returns of Pace Carbon requesting only minor modifications to previously filed returns. There were no changes to any of the filed Section 29 tax credit calculations. The Permanent Subcommittee on Investigations of the U.S. Senate's Committee on Governmental Affairs, however, has an ongoing investigation related to Section 29 tax credits.

Vectren believes it is justified in its reliance on the private letter rulings and recent IRS audit results for the Pace Carbon facilities. Therefore, the Company will continue to recognize Section 29 tax credits as they are earned until there is either a change in the tax code or the IRS' interpretation of that tax code.

Further, Section 29 tax credits are only available when the price of oil is less than a base price specified by the tax code, as adjusted for inflation. The Company does not believe that credits realized in 2004 and prior years will be affected by the limitation, but an average annual price in excess of the mid $50 per barrel range, as priced at the wellhead, could limit Section 29 tax credits in 2005 and beyond. In January 2005, the Company executed an insurance arrangement that partially limits the Company's exposure if a limitation on the availability of tax credits were to occur in 2005 and/or 2006 due to oil prices.

Utilicom Networks, LLC & Related Entities The Company has an approximate 2% equity interest and a convertible subordinated debt investment in Utilicom Networks, LLC (Utilicom) that if converted bring the Company's ownership interest up to 16%. The Company also has an approximate 19% equity interest in SIGECOM Holdings, Inc. (Holdings), which was formed by Utilicom to hold interests in SIGECOM, LLC (SIGECOM). SIGECOM provides broadband services, such as cable television, high-speed internet, and advanced local and long distance phone services, to the greater Evansville, Indiana area. The Company accounts for its investments in Utilicom and Holdings using the cost method of accounting.

Other Utilicom-related subsidiaries owned franchising agreements to provide broadband services to the greater Indianapolis, Indiana and Dayton, Ohio markets. In 2004, the build out of these markets was further evaluated, and the Company concluded that it was unlikely it would make additional investments in those markets. As a result, the Company recorded charges totaling $6.0 million, or $3.6 million after-tax, to write-off investments made in the Indianapolis and Dayton markets and to write down its investment in SIGECOM.

At December 31, 2004, convertible subordinated debt investments total $31.6 million, all of which is convertible into Utilicom ownership at the Company's option or upon the event of a public offering of stock by Utilicom. Investments in the convertible notes are included in Other investments. At December 31, 2004, and 2003, the Company's combined investment in equity and debt securities of Utilicom-related entities totaled $43.3 million and $47.7 million, respectively.

Other Affiliate Transactions
The Company has ownership interests in other affiliated companies accounted for using the equity method of accounting that perform underground construction and repair, facilities locating, and meter reading services to the Company. For the years ended December 31, 2004, 2003, and 2002, fees for these services and construction-related expenditures paid by the Company to its affiliates totaled $31.2 million, $37.2 million, and $38.3 million, respectively. Amounts charged by these affiliates are market based. Amounts owed to unconsolidated affiliates other than ProLiance totaled $1.1 million and $0.4 million at December 31, 2004, and 2003, respectively, and are included in Accounts payable to affiliated companies in the Consolidated Balance Sheets. Amounts due from unconsolidated affiliates included in Accounts receivable totaled $0.6 million and $0.4 million, respectively, at December 31, 2004, and 2003.

EITF 03-01
In March 2004, the EITF issued a consensus on Issue No. 03-01, "The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments" (EITF 03-01). In EITF 03-01, the Task Force developed a basic model for evaluating whether investments within the scope of EITF 03-01, which includes cost method and equity method investments, have other-than-temporary impairment. The basic model includes three steps: 1) determine if there is impairment; 2) if there is impairment, decide whether it is temporary or other than temporary; and
3) if it is other than temporary, recognize it in earnings. EITF 03-01 also requires certain qualitative and quantitative disclosure of material impairments judged to be temporary. The EITF has yet to finalize Steps 2 and 3. Step 1 and the disclosure requirements are currently effective, and the adoption of those portions of the EITF did not have a material effect on the Company.

As noted above, the Company incurred an other-than-temporary impairment charge associated with its cost method investment in SIGECOM, LLC, during 2004. While the Company currently believes that the book value of that investment approximates fair value, further changes in estimated fair value may occur.

Leveraged Leases
The Company is a lessor in three leveraged lease agreements under which real estate or equipment is leased to third parties. The total equipment and facilities cost was approximately $76.2 million at both December 31, 2004, and 2003, respectively. The cost of the equipment and facilities was partially financed by non-recourse debt provided by lenders who have been granted an assignment of rentals due under the leases and a security interest in the leased property, which they accepted as their sole remedy in the event of default by the lessee. Such debt amounted to approximately $48.3 million and $51.8 million at December 31, 2004, and 2003, respectively. At December 31, 2004 and 2003, the Company's leveraged lease investment, net of related deferred tax liabilities, was $7.0 million and $6.0 million, respectively.

Other Investments
Other investments include other notes receivable, the cash surrender value of life insurance policies, restricted cash, and a municipal bond, among other items.

These investment tax credits are amortized over the lives of the related investments. At December 31, 2004, the Company has alternative minimum tax carryforwards of $31.9 million, which do not expire.

6. Retirement Plans & Other Postretirement Benefits

At December 31, 2004, the Company maintains three qualified defined benefit pension plans, a nonqualified supplemental executive retirement plan (SERP), and three other postretirement benefit plans. The defined benefit pension and other postretirement benefit plans, which cover eligible full-time regular employees, are primarily noncontributory. The postretirement health care and life insurance plans are a combination of self-insured and fully insured plans. The Company has Voluntary Employee Beneficiary Association (VEBA) Trust Agreements for the partial funding of postretirement health benefits for retirees and their eligible dependents and beneficiaries. Annual VEBA funding is discretionary and is based on the projected cost over time of benefits to be provided to covered persons consistent with acceptable actuarial methods. To the extent these postretirement benefits are funded, the benefits are not liabilities in these consolidated financial statements. The detailed disclosures of benefit components that follow are based on an actuarial valuation using a measurement date as of September 30. The qualified pension plans and the SERP are aggregated under the heading "Pension Benefits." Other postretirement benefit plans are aggregated under the heading "Other Benefits."

FSP 106-2
On December 8, 2003, the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the "Medicare Act") was enacted. The Medicare Act introduces a Medicare prescription drug benefit, as well as a federal subsidy to sponsors of retiree health care benefit plans that provide a benefit that is at least "actuarially equivalent" to the Medicare benefit. In May 2004, FASB issued FASB Staff Position ("FSP") 106-2, "Accounting and Disclosure Requirements Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003," which supercedes FSP 106-1 of the same title issued in January 2004. FSP 106-2 provides guidance on the accounting and required disclosures for the effects of the Medicare Act for employers that sponsor postretirement health care plans that provide prescription drug benefits. FSP 106-2 was effective for the first interim or annual period beginning after June 15, 2004, with earlier adoption permitted.

The Company elected to early adopt the accounting for the federal subsidy under the Medicare Act on April 1, 2004, and remeasured its obligation as of January 1, 2004, to incorporate the impact of the Medicare Act which resulted in a reduction to the accumulated benefit obligation of $10.4 million. For the year ended December 31, 2004, the remeasurement resulted in a reduction in net periodic postretirement benefit cost of $0.8 million. The reduction is a component of amortization of actuarial loss (gain) in the information that follows.

The underlying determination of whether an employer's plan qualifies for the federal subsidy is still subject to clarifying federal regulations related to the Medicare Act. When this guidance is issued, the Company will reassess if its plans continue to qualify for the subsidy.

   Benefit obligation, end of period        $ 241.1     $ 222.7     $ 92.9    $ 97.3
=====================================================================================

The accumulated benefit obligation for all defined benefit pension plans was $219.5 million and $202.7 million at December 31, 2004, and 2003, respectively.

The benefit obligation as of December 31, 2004, and 2003, was calculated using the following weighted average assumptions:

-----------------------------------------------------------------------------------
                                             Pension Benefits        Other Benefits

Rate of compensation increase                3.50%      3.50%      3.50%     3.50%

To calculate the 2004 ending postretirement benefit obligation, a 9% annual rate of increase in the per capita cost of covered health care benefits was assumed for 2005. The rate was assumed to decrease gradually to 5% for 2009 and remain at that level thereafter. Assumed health care cost trend rates have a significant effect on the amounts reported for health care plans. A one percentage point increase in assumed health care cost trend rates would have increased the benefit obligation by $7.6 million. A one percentage point decrease would have decreased the obligation by $6.3 million. To calculate the 2003 ending postretirement benefit obligation, a 10% rate was assumed for 2004, declining to 5% in 2009 and remaining at that level thereafter.

The Company invests in a master trust that benefits its qualified defined benefit pension plans. The general investment objectives are to invest in a diversified portfolio, comprised of both equity and fixed income investments, which are further diversified among various asset classes. The diversification is designed to minimize the risk of large losses while maximizing total return within reasonable and prudent levels of risk. The investment objectives specify a targeted investment allocation for the pension plans of 60% equities, 35% debt, and 5% real estate for 2005, and for postretirement plans of 55% equities, 35% debt, and 10% short-term investments and other for 2005. Objectives do not target a specific return by asset class. The portfolio's return is monitored in total and is designed to outperform inflation. These investment objectives are long-term in nature.

At December 31, 2004, and 2003, all pension and postretirement plans had accumulated benefit obligations in excess of plan assets. As required by SFAS 87, the Company has recorded additional minimum pension liability adjustments to reflect the total unfunded accumulated liability arising from its pension plans. This additional minimum pension liability adjustment is included in Deferred credits & other liabilities. The offset to this additional liability is recorded to an intangible asset included in Other assets to the extent pension plans have unrecognized prior service cost. Any unfunded or unaccrued amount in excess of prior service cost is recorded in net of tax amounts to Accumulated other comprehensive income in shareholders' equity.

The effects of additional minimum pension liability adjustments at December 31, 2004, and 2003, follow:

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

To calculate the expected return on plan assets, the Company uses the plan assets' market-related value and an expected long-term rate of return. The fair market value of the assets at the measurement date is adjusted to a market-related value by recognizing the change in fair value experienced in a given year ratably over a five-year period.

Based on a targeted 60% equity, 35% debt, and 5% real estate allocation for the pension plans, the Company has used a long-term expected rate of return of 8.5% to calculate 2004 periodic benefit cost. For fiscal 2005, the expected long-term rate of return will be 8.25%.

In January 2005, the Company announced the amendment of certain postretirement benefit plans, effective January 1, 2006. The amendment will result in an estimated $3 million annual decrease in periodic cost, a portion of which will begin to be recognized in 2005, reducing those preliminary estimates. Two of the unions that represent bargaining employees at the Company's regulated subsidiaries have advised the Company that it is their position that these changes are not permitted under the existing collective bargaining agreements which govern the relationship between the employees and the affected subsidiaries. With assistance from legal counsel, management has analyzed the unions' position and continues to believe that the Company has reserved the right to amend the affected plans and that changing these benefits for retirees is not a mandatory subject of bargaining.

The weighted averages of significant assumptions used to determine net periodic benefit costs follow:

--------------------------------------------------------------------------------
                                    Pension Benefits          Other Benefits

Rate of compensation increase     3.50%   4.25%   4.75%    3.50%   4.25%   4.75%
Expected return on plan assets    8.50%   9.00%   9.00%    8.50%   9.00%   9.00%

To measure 2004 postretirement expense, the Company used a 10% healthcare cost trend rate for 2004, declining to 5% in 2009 and remaining level thereafter. A one percentage point increase in assumed health care cost trend rates would have increased the 2004 service and interest cost components of pension costs by $0.6 million. A one percentage point decrease would have decreased the 2004 benefit costs by $0.5 million. To measure 2003 postretirement expense, the Company used a 10% healthcare cost trend rate for 2003, declining to 5% in 2007 and remaining level thereafter.

Defined Contribution Plan
The Company also has defined contribution retirement savings plans that are qualified under sections 401(a) and 401(k) of the Internal Revenue Code. During 2004, 2003, and 2002, the Company made contributions to these plans of $3.5 million, $3.6 million, and $3.0 million, respectively.

VUHI 2003 Issuance
In July 2003, VUHI issued senior unsecured notes with an aggregate principal amount of $200 million in two $100 million tranches. The first tranche was 10-year notes due August 2013, with an interest rate of 5.25% priced at 99.746% to yield 5.28% to maturity (2013 Notes). The second tranche was 15-year notes due August 2018 with an interest rate of 5.75% priced at 99.177% to yield 5.80% to maturity (2018 Notes).

The notes have no sinking fund requirements, and interest payments are due semi-annually. The notes may be called by VUHI, in whole or in part, at any time for an amount equal to accrued and unpaid interest, plus the greater of 100% of the principal amount or the sum of the present values of the remaining scheduled payments of principal and interest, discounted to the redemption date on a semi-annual basis at the Treasury Rate, as defined in the indenture, plus 20 basis points for the 2013 Notes and 25 basis points for the 2018 Notes.

Shortly before these issues, VUHI entered into several treasury locks with a total notional amount of $150.0 million. Upon issuance of the debt, the treasury locks were settled resulting in the receipt of $5.7 million in cash, which was recorded as a regulatory liability pursuant to existing regulatory orders. The value received is being amortized as a reduction of interest expense over the life of the issues.

The net proceeds from the sale of the senior notes and settlement of related hedging arrangements approximated $203 million.

Long-Term Debt Put & Call Provisions
Certain long-term debt issues contain put and call provisions that can be exercised on various dates before maturity. Other than those described below related to ratings triggers, the put or call provisions are not triggered by specific events, but are based upon dates stated in the note agreements, such as when notes are re-marketed. During 2004, 2003, and 2002, debt totaling $2.5 million, $0.1 million, and $5.2 million, respectively, was put to the Company. Debt which may be put to the Company during the years following 2004 (in millions) is $10.0 in 2005, zero in 2006, $20.0 in 2007, zero in 2008, $80.0 in 2009, and $40.0 thereafter. Debt that may be put to the Company within one year is classified as Long-term debt subject to tender in current liabilities.

SIGECO and Indiana Gas Debt Call
During 2004, the Company called $20.0 million of insured quarterly senior unsecured notes outstanding at Indiana Gas. The notes, originally due in 2015, were called at par.

During 2003, the Company called two first mortgage bonds outstanding at SIGECO and two senior unsecured notes outstanding at Indiana Gas. The first SIGECO bond had a principal amount of $45.0 million, an interest rate of 7.60%, was originally due in 2023, and was redeemed at 103.745% of its stated principal amount. The second SIGECO bond had a principal amount of $20.0 million, an interest rate of 7.625%, was originally due in 2025, and was redeemed at 103.763% of the stated principal amount.

The first Indiana Gas note had a remaining principal amount of $21.3 million, an interest rate of 9.375%, was originally due in 2021, and was redeemed at 105.525% of the stated principal amount. The second Indiana Gas note had a principal amount of $13.5 million, an interest rate of 6.75%, was originally due in 2028, and was redeemed at the principal amount.

Pursuant to regulatory authority, the premiums paid to retire the net carrying value of these notes totaling $3.6 million were deferred in Regulatory assets.

Other Financing Transactions

During 2004, the Company remarketed two first mortgage bonds outstanding at SIGECO. The remarketing effort converted $32.8 million of outstanding fixed rate debt into variable rate debt where interest rates reset weekly. One bond, due in 2023, had a principal amount of $22.8 million and an interest rate of 6%. The other bond, due in 2015, had a principal amount of $10.0 million and an interest rate of 4.3%. These remarketing efforts resulted in the extinguishment of debt and the reissuance of new debt at generally the same par value. These bonds are classified in Long-term debt.

During 2003, the Company remarketed $26.6 million of adjustable rate senior unsecured bonds and $22.5 million of adjustable rate first mortgage bonds. Of the remarketed unsecured bonds, $4.6 million were placed through 2020 at a 4.5% fixed interest rate, $22.0 million were placed through 2030 at a 5.0% fixed interest rate, and the $22.5 million first mortgage bonds were placed through 2024 at a 4.65% fixed interest rate. These bonds are classified in Long-term debt.

Other Company debt totaling $15.0 million in 2004, $18.5 million in 2003, and $6.5 million in 2002 was retired as scheduled.

Future Long-Term Debt Sinking Fund Requirements & Maturities The annual sinking fund requirement of SIGECO's first mortgage bonds is 1% of the greatest amount of bonds outstanding under the Mortgage Indenture. This requirement may be satisfied by certification to the Trustee of unfunded property additions in the prescribed amount as provided in the Mortgage Indenture. SIGECO intends to meet the 2005 sinking fund requirement by this means and, accordingly, the sinking fund requirement for 2005 is excluded from Current liabilities in the Consolidated Balance Sheets. At December 31, 2004, $563.9 million of SIGECO's utility plant remained unfunded under SIGECO's Mortgage Indenture. SIGECO's gross utility plant balance subject to the Mortgage Indenture approximated $1.8 billion at December 31, 2004.

Consolidated maturities and sinking fund requirements on long-term debt during the five years following 2004 (in millions) are $38.5 in 2005, zero in 2006, $24.0 in 2007, zero in 2008 and in 2009.

Covenants
Both long-term and short-term borrowing arrangements contain customary default provisions; restrictions on liens, sale leaseback transactions, mergers or consolidations, and sales of assets; and restrictions on leverage and interest coverage, among other restrictions. As of December 31, 2004, the Company was in compliance with all financial covenants.

Ratings Triggers
At December 31, 2004, $113.0 million of Vectren Capital's senior unsecured notes were subject to cross-default and ratings trigger provisions that would provide that the full balance outstanding is subject to prepayment if the ratings of Indiana Gas or SIGECO declined to BBB/Baa2. In addition, accrued interest and a make whole amount based on the discounted value of the remaining payments due on the notes would also become payable. The credit rating of Indiana Gas' senior unsecured debt and SIGECO's secured debt remains one level and two levels, respectively, above the ratings trigger.

Debt Guarantees
Vectren Corporation guarantees Vectren Capital's long-term and short-term debt, which totaled $113.0 million and $104.0 million, respectively, at December 31, 2004. VUHI's currently outstanding long-term and short-term debt is jointly and severally guaranteed by Indiana Gas, SIGECO, and VEDO. VUHI's long-term and short-term debt outstanding at December 31, 2004, totaled $550.0 million and $308.0 million, respectively.

8. Cumulative Preferred Stock of Subsidiary

Currently outstanding redeemable preferred stock has a dividend rate of 8.50% and in the event of involuntary liquidation the amount payable is $100 per share, plus accrued dividends. This series may be redeemed at $100 per share, plus accrued dividends on any of its dividend payment dates, and is also callable at the Company's option at a rate of 1,160 shares per year. As of December 31, 2004, and 2003, there were 1,177 shares and 2,277 shares outstanding, respectively.

9. Earnings Per Share

Basic earnings per share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share assumes the conversion of stock options into common shares and the lifting of restrictions on issued restricted shares using the treasury stock method to the extent the effect would be dilutive. The following table illustrates the basic and dilutive earnings per share calculations for the three years ended December 31, 2004:

Options to purchase 4,200 shares of common stock for the year ended December 31, 2004, 530,663 shares of common stock for the year ended December 31, 2003, and 87,963 shares of common stock for the year ended December 31, 2002, were excluded in the computation of dilutive earnings per share because the options' exercise price was greater than the average market price of a share of common stock during the period. Exercise prices for options excluded from the computation were $25.59 in 2004; $23.19 to $25.59 in 2003; and $24.05 to $25.59 in 2002.

10. Share-Based Incentive Plans

The Company has various share-based incentive plans to encourage executives, strategic employees, and non-employee directors to remain with the Company and to more closely align their interest with those of the Company's shareholders.

Stock Option Plans
Stock options granted to employees in 2004 and 2003 become fully vested and exercisable at the end of three years. Stock options granted to employees in 2001 and 2002 become fully vested and exercisable at the end of five years. Stock options granted to non-employee directors since 2001 become fully vested and exercisable at the end of one year. All options granted prior to 2001 are fully vested and exercisable. Options granted both before and after 2001 generally expire ten years from the date of grant. Options generally vest on a straight-line graded basis over their terms.

A summary of activity within the Company's stock option plans for the past three years follows:

                                                                  Wtd. Avg.

11. Common Shareholders' Equity

Equity Issuance
In March 2003, the Company filed a registration statement with the Securities and Exchange Commission with respect to a public offering of authorized but previously unissued shares of common stock as well as the senior unsecured notes of VUHI described above in Note 7. In August 2003, the registration became effective, and an agreement was reached to sell approximately 7.4 million shares to a group of underwriters. The net proceeds totaled $163.2 million.

Authorized, Reserved Common and Preferred Shares At December 31, 2004, and 2003, the Company was authorized to issue 480.0 million shares of common stock and 20.0 million shares of preferred stock. Of the authorized common shares, approximately 9.4 million shares at December 31, 2004, and 7.0 million shares at December 31, 2003, were reserved by the board of directors for issuance through the Company's share-based compensation plans, benefit plans, and dividend reinvestment plan. At December 31, 2004, and 2003, there were 394.6 million and 397.4 million, respectively, of authorized shares of common stock and all authorized shares of preferred stock available for a variety of general corporate purposes, including future public offerings to raise additional capital and for facilitating acquisitions.

Shareholder Rights Agreement
The Company's board of directors adopted a Shareholder Rights Agreement (Rights Agreement). As part of the Rights Agreement, the board of directors declared a dividend distribution of one right for each outstanding Vectren common share. Each right entitles the holder to purchase from Vectren one share of common stock at a price of $65.00 per share (subject to adjustment to prevent dilution). The rights become exercisable 10 days following a public announcement that a person or group of affiliated or associated persons (Vectren Acquiring Person) has acquired beneficial ownership of 15% or more of the outstanding Vectren common shares (or a 10% acquirer who is determined by the board of directors to be an adverse person), or 10 days following the announcement of an intention to make a tender offer or exchange offer, the consummation of which would result in any person or group becoming a Vectren Acquiring Person. The Vectren Shareholder Rights Agreement expires October 21, 2009.

12. Commitments & Contingencies

Commitments
Future minimum lease payments required under operating leases that have initial or remaining noncancelable lease terms in excess of one year during the five years following 2004 and thereafter (in millions) are $5.6 in 2005, $4.5 in 2006, $3.6 in 2007, $1.5 in 2008, $0.5 in 2009 and $1.8 thereafter. Total lease expense (in millions) was $6.7 in 2004, $7.2 in 2003, and $7.3 in 2002.

Firm purchase commitments for commodities total (in millions) $152.1 million in 2005 and $1.4 million in 2006. Firm purchase commitment for utility and non-utility plant total $20.5 million.

Other Guarantees
Vectren issues guarantees to third parties on behalf of its unconsolidated affiliates. Such guarantees allow those affiliates to execute transactions on more favorable terms than the affiliate could obtain without such a guarantee. Guarantees may include posted letters of credit, leasing guarantees, and performance guarantees. As of December 31, 2004, guarantees issued and outstanding on behalf of unconsolidated affiliates approximated $5 million. The Company has also issued a guarantee approximating $4 million related to the residual value of an operating lease that expires in 2006.

Vectren has accrued no liabilities for these guarantees as they relate to guarantees issued among related parties, are not material, or such guarantees were executed prior to the adoption of FASB Interpretation No. 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others." Liabilities accrued for, and activity related to, product warranties are not significant.

Securities & Exchange Commission Inquiry into PUCHA Exemption

In July 2004, the Company received a letter from the SEC regarding its exempt status under the Public Utility Holding Company Act of 1935 (PUHCA). The letter asserts that Vectren's out of state electric power sales exceed the amount previously determined by the SEC to be acceptable in order to qualify for the exemption. There is pending a request by Vectren for an order of exemption under
Section 3(a)(1) of PUHCA. Vectren also claims the benefit of the exemption pursuant to Rule 2 under Section 3(a)(1) of PUHCA by filing an annual statement on SEC Form U-3A-2. The Company has responded to the SEC inquiry and filed an amended Form U-3A-2 for the year ended December 31, 2003. The amendment changed the method of aggregating wholesale power sales and purchases outside of Indiana from that previously reported. The new method is to aggregate by delivery point. The amendment also submitted clarifications as to activity outside of Indiana related to gas utility operations.

Legal Proceedings
The Company is party to various legal proceedings arising in the normal course of business. In the opinion of management, there are no legal proceedings pending against the Company that are likely to have a material adverse effect on its financial position. See the ProLiance discussion in Note 3.

13. Environmental Matters

Clean Air Act

NOx SIP Call Matter
The Company has taken steps to comply with Indiana's State Implementation Plan (SIP) of the Clean Air Act (the Act). These steps include installing Selective Catalytic Reduction (SCR) systems at Culley Generating Station Unit 3 (Culley), Warrick Generating Station Unit 4, and A.B. Brown Generating Station Units 1 and
2. SCR systems reduce flue gas NOx emissions to atmospheric nitrogen and water using ammonia in a chemical reaction. This technology is known to currently be the most effective method of reducing nitrogen oxide (NOx) emissions where high removal efficiencies are required.

The IURC has issued orders that approve:
o the Company's project to achieve environmental compliance by investing in clean coal technology;
o a total capital cost investment for this project up to $244 million (excluding AFUDC), subject to periodic review of the actual costs incurred;
o a mechanism whereby, prior to an electric base rate case, the Company may recover through a rider that is updated every six months, an 8% return on its weighted capital costs for the project; and
o ongoing recovery of operating costs, including depreciation and purchased emission allowances, related to the clean coal technology once the facility is placed into service.

Based on the level of system-wide emissions reductions required and the control technology utilized to achieve the reductions, the current estimated construction cost is consistent with amounts approved in the IURC's orders. Through December 31, 2004, $238 million has been expended, and three of the four SCR's are operational. Once all equipment is installed and operational, related annual operating expenses, including depreciation expense, are estimated to be between $24 million and $27 million. The Company is recovering the operational costs associated with the SCR's and related technology. The 8% return on capital investment approximates the return authorized in the Company's last electric rate case in 1995 and includes a return on equity.

The Company has achieved timely compliance through the reduction of the Company's overall NOx emissions to levels compliant with Indiana's NOx emissions budget allotted by the USEPA. Therefore, the Company has recorded no accrual for potential penalties that may result from noncompliance.

Culley Generating Station Litigation
During 2003, the U.S. District Court for the Southern District of Indiana entered a consent decree among SIGECO, the Department of Justice (DOJ), and the USEPA that resolved a lawsuit originally brought by the USEPA against SIGECO. The lawsuit alleged violations of the Clean Air Act by SIGECO at its Culley Generating Station for (1) making modifications to generating station without obtaining required permits, (2) making major modifications to the generating station without installing the best available emission control technology, and
(3) failing to notify the USEPA of the modifications.

Under the terms of the agreement, the DOJ and USEPA agreed to drop all challenges of past maintenance and repair activities at the Culley Generating Station. In reaching the agreement, SIGECO did not admit to any allegations in the government's complaint, and SIGECO continues to believe that it acted in accordance with applicable regulations and conducted only routine maintenance on the units. SIGECO entered into this agreement to further its continued commitment to improve air quality and avoid the cost and uncertainties of litigation.

Under the agreement, SIGECO committed to
o either repower Culley Unit 1 (50 MW) with natural gas and equip it with SCR control technology for further reduction of nitrogen oxide, or cease operation of the unit by December 31, 2006;
o operate the existing SCR control technology recently installed on Culley Unit 3 (287 MW) year round at a lower emission rate than that currently required under the NOx SIP Call, resulting in further nitrogen oxide reductions;
o enhance the efficiency of the existing scrubber at Culley Units 2 and 3 for additional removal of sulphur dioxide emissions;
o install a baghouse for further particulate matter reductions at Culley Unit 3 by June 30, 2007;

o conduct a Sulphuric Acid Reduction Demonstration Project as an environmental mitigation project designed to demonstrate an advance in pollution control technology for the reduction of sulfate emissions; and
o pay a $600,000 civil penalty.

The Company notified the USEPA of its intention to shut down Culley Unit 1 effective December 31, 2006. The Company does not believe that implementation of the settlement will have a material effect to its results from operations or financial condition. The $600,000 civil penalty was accrued during 2003 and is reflected in Other-net.

On January 23, 2001, SIGECO received an information request from the USEPA under
Section 114 of the Clean Air Act for historical operational information on the Warrick and A.B. Brown generating stations. SIGECO has provided all information requested with the most recent correspondence provided on March 26, 2001.

Manufactured Gas Plants
In the past, Indiana Gas, SIGECO, 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, SIGECO, and 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 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 the IDEM's Voluntary Remediation Program (VRP) and is currently conducting some level of remedial activities, including groundwater monitoring at certain sites, where deemed appropriate, and will continue remedial activities at the sites as appropriate and necessary.

In conjunction with data compiled by environmental consultants, Indiana Gas has accrued the estimated costs for further investigation, remediation, groundwater monitoring, and related costs for the sites. While the total costs that may be incurred in connection with addressing these sites cannot be determined at this time, Indiana Gas has recorded costs that it reasonably expects to incur totaling approximately $20.4 million.

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

With respect to insurance coverage, Indiana Gas has received and recorded settlements from all known insurance carriers in an aggregate amount approximating $20.4 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.

In October 2002, the Company received a formal information request letter from the IDEM regarding five manufactured gas plants owned and/or operated by SIGECO and not currently enrolled in the IDEM's VRP. In response, SIGECO submitted to the IDEM the results of preliminary site investigations conducted in the mid-1990's. These site investigations confirmed that based upon the conditions known at the time, the sites posed no risk to human health or the environment. Follow up reviews have been initiated by the Company to confirm that the sites continue to pose no such risk.

On October 6, 2003, SIGECO filed applications to enter four of the manufactured gas plant sites in IDEM's VRP. The remaining site is currently being addressed in the VRP by another Indiana utility. SIGECO added those four sites into the renewal of the global Voluntary Remediation Agreement that Indiana Gas has in place with IDEM for its manufactured gas plant sites. That renewal was approved by the IDEM on February 24, 2004. On July 13, 2004, SIGECO filed a declaratory judgment action against its insurance carriers seeking a judgment finding its carriers liable under the policies for coverage of further investigation and any necessary remediation costs that SIGECO may accrue under the VRP program. The total investigative costs, and if necessary, costs of remediation at the four SIGECO sites, as well as the amount of any PRP or insurance recoveries, cannot be determined at this time.

Jacobsville Superfund Site
On July 22, 2004, the USEPA listed the Jacobsville Neighborhood Soil Contamination site in Evansville, Indiana, on the National Priorities List under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). The USEPA has identified four sources of historic lead contamination. These four sources shut down manufacturing operations years ago. When drawing up the boundaries for the listing, the USEPA included a 250 acre block of properties surrounding the Jacobsville neighborhood, including Vectren's Wagner Operations Center. Vectren's property has not been named as a source of the lead contamination, nor does the USEPA's soil testing to date indicate that the Vectren property contains lead contaminated soils. Vectren's own soil testing, completed during the construction of the Operations Center, did not indicate that the Vectren property contains lead contaminated soils. At this time, Vectren anticipates only additional soil testing, if required by the USEPA.

14. Rate & Regulatory Matters

SIGECO and Indiana Gas Base Rate Settlements On June 30, 2004, the IURC approved a $5.7 million base rate increase for SIGECO's gas distribution business, and on November 30, 2004, approved a $24 million base rate increase for Indiana Gas' gas distribution business. The new rate designs include a larger service charge, which is intended to address to some extent earnings volatility related to weather. The base rate change in SIGECO's service territory was implemented on July 1, 2004, resulting in additional 2004 revenues of $2.5 million. The base rate change in Indiana Gas' service territory was implemented on December 1, 2004, resulting in additional 2004 revenues of $2.2 million.

The orders also permit SIGECO and Indiana Gas to recover the on-going costs to comply with the federal Pipeline Safety Improvement Act of 2002. The Pipeline Safety Improvement Tracker provides for the recovery of incremental non-capital dollars, capped at $750,000 the first year and $500,000 thereafter for SIGECO and $2.5 million per year for Indiana Gas. Any costs incurred in excess of these annual caps are to be deferred for future recovery.

VEDO Pending Base Rate Increase Settlement On February 4, 2005, the Company filed with the PUCO a settlement agreement that had been entered into with several parties, including the PUCO staff, in its base rate case. The Ohio Office of the Consumer Counselor (OCC) is opposing the settlement. Earlier in 2004 VEDO had filed with the PUCO a request to adjust its base rates and charges for its gas distribution business serving more than 315,000 customers located in west central Ohio. The settlement provides for a $15.7 million increase in VEDO's base distribution rates to cover the ongoing costs of operating, maintaining, and expanding the approximately 5,200-mile distribution system. The settlement increase includes $1.1 million of funding for weatherization and conservation programs for low income customers. Evidentiary hearings were completed in the case on February 9, 2005. Review and approval by the PUCO is necessary before the settlement is effective. The proposed new rate design includes a larger service charge, which will address, to some extent, earnings volatility related to weather. The settlement also permits VEDO the annual recovery of on-going costs associated with the Pipeline Safety Improvement Act of 2002. Based upon the PUCO's actions in other proceedings, the Company would expect an order near the end of the first quarter of 2005.

Ohio Uncollectible Accounts Expense Tracker On December 17, 2003, the PUCO approved a request by VEDO and several other regulated Ohio gas utilities to establish a mechanism to recover uncollectible account expense outside of base rates. The tariff mechanism establishes an automatic adjustment procedure to track and recover these costs instead of providing the recovery of the historic amount in base rates. Through this order, VEDO received authority to defer its 2003 uncollectible accounts expense to the extent it differs from the level included in base rates. The Company estimated the difference to approximate $4 million in excess of that included in base rates, and reversed and deferred that amount for future recovery. In 2004, the Company recorded revenues of $3.3 million which is equal to the level of uncollectible accounts expense recognized for Ohio residential customers.

Gas Cost Recovery (GCR) Audit Proceedings There is an Ohio requirement that Ohio gas utilities undergo a biannual audit of their gas acquisition practices in connection with the gas cost recovery (GCR) mechanism. In the case of VEDO, a two-year audit period ended in November 2002. That audit period provided the PUCO staff its initial review of the portfolio administration arrangement between VEDO and ProLiance. The external auditor retained by the PUCO staff submitted an audit report in the fall of 2003 wherein it recommended a disallowance of approximately $7 million of previously recovered gas costs. The Company believes a large portion of the third party auditor recommendations is without merit. A hearing has been held, and the PUCO staff has recommended a $6.1 million disallowance. The Ohio Consumer Counselor has recommended an $11.5 million disallowance. For this PUCO audit period, any disallowance relating to the Company's ProLiance arrangement will be shared by the Company's joint venture partner. Based on a review of the matters, the Company has recorded $1.1 million for its estimated share of a potential disallowance. A PUCO decision on this matter is yet to be issued. The Company is also unable to determine the effects that a PUCO decision for the audit period ended in November 2002 may have on results in audit periods beginning after November 2002.

15. Derivatives & Other Financial Instruments

Accounting Policy for Derivatives
The Company executes derivative contracts in the normal course of operations while buying and selling commodities to be used in operations, optimizing its generation assets, and managing risk. The Company accounts for its derivative contracts in accordance with SFAS 133, "Accounting for Derivatives" and its related amendments and interpretations. In most cases, SFAS 133 requires a derivative to be recorded on the balance sheet as an asset or liability measured at its market value and that a change in the derivative's market value be recognized currently in earnings unless specific hedge criteria are met.

When an energy contract that is a derivative is designated and documented as a normal purchase or normal sale, it is exempted from mark-to-market accounting. Otherwise, energy contracts and financial contracts that are derivatives are recorded at market value as current or noncurrent assets or liabilities depending on their value and on when the contracts are expected to be settled. The offset resulting from carrying the derivative at fair value on the balance sheet is charged to earnings unless it qualifies as a hedge or is subject to SFAS 71. When hedge accounting is appropriate, the Company assesses and documents hedging relationships between the derivative contract and underlying risks as well as its risk management objectives and anticipated effectiveness. When the hedging relationship is highly effective, derivatives are designated as hedges. The market value of the effective portion of the hedge is marked to market in accumulated other comprehensive income for cash flow hedges or as an adjustment to the underlying's basis for fair value hedges. The ineffective portion of hedging arrangements is marked-to-market through earnings. The offset to contracts affected by SFAS 71 are marked-to-market as a regulatory asset or liability. Market value for derivative contracts is determined using quoted market prices from independent sources. Following is a more detailed discussion of the Company's use of mark-to-market accounting in three primary areas: asset optimization, natural gas procurement, and interest rate management.

Asset Optimization
Periodically, generation capacity is in excess of that needed to serve native load and firm wholesale customers. The Company markets this unutilized capacity to optimize the return on its owned generation assets. Substantially all of the margin from these activities is generated from contracts that are integrated with portfolio requirements around power supply and delivery and are short-term purchase and sale transactions that expose the Company to limited market risk. Contracts with counter-parties subject to master netting arrangements are presented net in the Consolidated Balance Sheets. Asset optimization contracts are recorded at market value.

Asset optimization contracts recorded at market value at December 31, 2004, totaled $2.5 million of Prepayments & other current assets and $3.1 million of Accrued liabilities, compared to $2.4 million of Prepayments & other current assets and $2.8 million of Accrued liabilities at December 31, 2003.

The proceeds received and paid upon settlement of both purchase and sale contracts along with changes in market value of open contracts are recorded in Electric utility revenues. The change in market value is a function of the normal decline in market value as earnings are realized and the fluctuation in market value resulting from price volatility. Net revenues from asset optimization activities totaled $23.8 million in 2004, $26.5 million in 2003, and $23.3 million in 2002.

Natural Gas Procurement Activity
The Company's regulated operations have limited exposure to commodity price risk for purchases and sales of natural gas and electricity for retail customers due to current Indiana and Ohio regulations which, subject to compliance with those regulations, allow for recovery of such purchases through natural gas and fuel cost adjustment mechanisms. Although Vectren's regulated operations are exposed to limited commodity price risk, volatile natural gas prices can result in higher working capital requirements, increased expenses including unrecoverable interest costs, uncollectible accounts expense, and unaccounted for gas, and some level of price- sensitive reduction in volumes sold. The Company mitigates these risks by executing derivative contracts that manage the price of forecasted natural gas purchases. These contracts are subject to regulation which allows for reasonable and prudent hedging costs to be recovered through rates. When regulation is involved, SFAS 71 controls when the offset to mark-to-market accounting is recognized in earnings.

The Company's wholly owned gas retail operations also mitigate price risk associated with forecasted natural gas purchases by using derivatives. Such contracts are ordinarily designated and documented as cash flow hedges. These nonregulated gas retail operations may also from time-to-time execute weather derivatives to mitigate extreme weather affecting unregulated gas retail sales. At December 31, 2004 and 2003, the market values of these contracts and the book value of weather contracts were not significant.

Interest Rate Management
The Company is exposed to interest rate risk associated with its borrowing arrangements. Its risk management program seeks to reduce the potentially adverse effects that market volatility may have on interest expense. The Company has used interest rate swaps and treasury locks to hedge forecasted debt issuances and other interest rate swaps to manage interest rate exposure. Hedging instruments are recorded at market value. Changes in market value, when effective, are recorded in Accumulated other comprehensive income for cash flow hedges, as an adjustment to the outstanding debt balance for fair value hedges, or as regulatory asset/liability when regulation is involved. Amounts are recorded to interest expense as settled.

Interest rate swaps hedging the fair value of fixed-rate debt with a total notional amount of $55.5 million are outstanding. The fair value liability associated with those swaps was $0.5 million and $0.3 million, respectively, at December 31, 2004 and 2003. At December 31, 2004, approximately $5.5 million remains in Regulatory liabilities related to future interest payments. Of the existing regulatory liability, $0.6 million will be reclassified to earnings in 2005, $0.6 million was reclassified to earnings in 2004, and $0.3 million was reclassified to earnings during 2003.

Fair Value of Other Financial Instruments The carrying values and estimated fair values of the Company's other financial instruments follow:

                                              At December 31,
------------------------------------------------------------------------------

                             -----------------------  ------------------------

(In millions)                  Amount       Value        Amount        Value
---------------------------  -----------------------  ------------------------

   Long-term debt            $ 1,070.2    $ 1,146.2    $ 1,106.5    $ 1,184.8
   Short-term borrowings &
     notes payable               412.4        412.4        274.9        274.9

Certain methods and assumptions must be used to estimate the fair value of financial instruments. The fair value of the Company's long-term debt was estimated based on the quoted market prices for the same or similar issues or on the current rates offered to the Company for instruments with similar characteristics. Because of the maturity dates and variable interest rates of short-term borrowings, its carrying amount approximates its fair value.

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. Accordingly, any reacquisition would not be expected to have a material effect on the Company's results of operations.

Periodically, the Company tests its cost method investments and notes receivable for impairment which may require their fair value to be estimated. Because of the customized nature of these investments and lack of a readily available market, it is not practicable to estimate the fair value of these financial instruments at specific dates without considerable effort and costs. At December 31, 2004, and 2003, fair value for these financial instruments was not estimated.

16. Segment Reporting

The Company segregates its operations into three groups: 1) Utility Group,
2) Nonregulated Group, and 3) Corporate and Other.

The Utility Group is comprised of Vectren Utility Holdings, Inc.'s operations, which consist of the Company's regulated operations and other operations that provide information technology and other support services to those regulated operations. The Company segregates its regulated operations into a Gas Utility Services operating segment and an Electric Utility Services operating segment. The Gas Utility Services segment provides natural gas distribution and transportation services to nearly two-thirds of Indiana and to west central Ohio. The Electric Utility Services segment provides electric distribution services primarily to southwestern Indiana, and includes the Company's power generating and marketing operations. The Company cross manages its regulated operations as separated between Energy Delivery, which includes the gas and electric transmission and distribution functions, and Power Supply, which includes the power generating and marketing operations. For these regulated operations the Company uses after tax operating income as a measure of profitability, consistent with regulatory reporting requirements. For the Utility Group's other operations, net income is used as the measure of profitability.

In total, there are three operating segments of the Utility Group as defined by SFAS 131 "Disclosure About Segments of an Enterprise and Related Information" (SFAS 131).

The Nonregulated Group is comprised of one operating segment as defined by SFAS 131 that includes various subsidiaries and affiliates offering and investing in energy marketing and services, coal mining, utility infrastructure services, and broadband communications, among other energy-related opportunities.

Corporate and Other includes unallocated corporate expenses such as branding and charitable contributions, among other activities, that benefit the Company's other operating segments. Net income is the measure of profitability used by management for both the Nonregulated Group and Corporate and Other. Information related to the Company's business segments is summarized below:

SOUTHERN INDIANA GAS AND ELECTRIC COMPANY

FIRST MORTGAGE BOND, SERIES B 1993 DUE 2023

This bond is one of an issue of First Mortgage Bonds of the Company, issuable in series, and is one of the series designated in the title hereof, all issued and to be issued under and equally secured (except as to any sinking fund established in accordance with the provisions of the Mortgage hereinafter mentioned for the bonds of any particular series) by an Indenture of Mortgage and Deed of Trust, dated as of April 1, 1932, executed by the Company to Deutsche Bank Trust Company Americas, formerly known as Bankers Trust Company, as Trustee (the "Trustee"), as amended and supplemented by indentures supplemental thereto, including without limitation a Supplemental Indenture dated as of May 1, 1993, as particularly supplemented and amended by a Supplemental Indenture dated as of August 1, 2004, to which Indenture as amended and supplemented (herein referred to as the "Mortgage") reference is made for a description of the property mortgaged and pledged, the nature and extent of the security, the rights of the holders of the bonds in respect thereof and the terms and conditions upon which the bonds are secured.

The bonds of this series are issued and to be issued in order to evidence and secure a loan made by the County to the Company pursuant to a Loan Agreement dated as of May 1, 1993, as supplemented and amended. In order to provide moneys to fund such loan, the County has issued the Warrick County Bonds under and pursuant to the County Indenture. Payments made by the Company of principal and interest on the bonds of this series are intended to be sufficient to permit payments of principal and interest to be made on the Warrick County Bonds. Upon certain terms and conditions, moneys held under and pursuant to the County Indenture, including moneys so held from the proceeds of the sale of the Warrick County Bonds or earnings on the investment of such proceeds, or redemption of the Warrick County Bonds shall be credited to or used for the payment of the bonds of this series and to the extent so credited or used shall satisfy a like amount otherwise due hereunder.

The bonds of this series are subject to optional and mandatory redemption, in whole or in part, as the case may be, on each date that Warrick County Bonds are to be redeemed. The principal amount of the bonds of this series to be redeemed on any such date shall be equal to the principal amount of Warrick County Bonds called for redemption on that date. All redemptions of bonds of this series shall be at 100% of the principal amount thereof, plus accrued interest to the redemption date.

If and whenever the Trustee or the Company is notified that an event of default has occurred and is continuing under Section 9.01(e) of the County Indenture, and provided that the principal of all Warrick County Bonds then outstanding and the interest thereon shall have been declared immediately due and payable, then not later than two business days following the occurrence of the foregoing events, the Company shall, upon not less than 30 days' and not more than 45 days' prior written notice given in the manner provided in the Mortgage, call for redemption on a redemption date selected by it not later than 45 days following the date of such notice, all of the Bonds of this series then outstanding, and shall on such redemption date redeem the same at a price equal to 100% of the principal amount thereof, together with accrued interest thereon to the redemption date, except that such requirement or redemption shall be deemed to be waived if, prior to the date fixed for such redemption of the bonds of this series, such event of default is waived or cured.

In case a completed default, as defined in the Mortgage, shall occur, the principal of this bond and all other bonds of the Company at any such time outstanding under the Mortgage may be declared or may become due and payable, upon the conditions and in the manner and with the effect provided in the Mortgage. The Mortgage provides that such declaration may in certain events be waived by the holders of a majority in principal amount of the bonds entitled to vote then outstanding.

This bond, subject to the limitations with regard thereto contained in the County Indenture, is transferable as prescribed in the Mortgage by the registered owner hereof in person, or by his duly authorized attorney, at the office or agency of the Company in the Borough of Manhattan, The City of New York, N.Y., upon surrender and cancellation of this bond, and thereupon, a new fully registered bond of the same series for a like principal amount will be issued to the transferee in exchange thereof as provided in the Mortgage, and upon payment, if the Company shall require it, of the charges therein prescribed. The Company and the Trustee may deem and treat the person in whose name this bond is registered as the absolute owner for the purpose of receiving payment of or on account of the principal and interest due hereon and for all other purposes.

As provided in Section 8.02 of the County Indenture, from and after the Release Date (as defined in the County Indenture), the obligations of the Company with respect to this bond shall be deemed to be satisfied and discharged, this bond shall cease to secure in any manner the Company's obligations under the Agreement with respect to the payment of any County Bonds outstanding under the County Indenture, and, pursuant to
Section 8.02 of the County Indenture, the County Trustee shall forthwith deliver this Bond to the Company for cancellation.

The Bonds of this series are issuable as registered bonds without coupons in denominations of $1,000 and authorized multiples thereof. In the manner and upon payment of the charges prescribed in the Mortgage, registered bonds without coupons of this series may be exchanged for a like aggregate principal amount of fully registered bonds without coupons of other authorized denominations of the same series, upon presentation and surrender thereof, for cancellation, to the Trustee at its principal corporate trust office in the Borough of Manhattan, The City of New York, N.Y.

No recourse shall be had for the payment of the principal of or interest on this bond against any incorporator or any past, present or future subscriber to the capital stock, stockholder, officer or director of the Company or of any predecessor or successor corporation, either directly or through the Company or any predecessor or successor corporation, under any rule of law, statute or constitution or by the enforcement of any assessment or otherwise, all such liability of incorporators, subscribers, stockholders, officers and directors being released by the holder or owner hereof by the acceptance of this bond and being likewise waived and released by the terms of the Mortgage.

Pursuant to the Mortgage, the holder or owner of this bond by his acceptance hereof is deemed to have agreed to amendments to the Mortgage which will eventually permit certain amendments to the Mortgage with the consent of the holders of 66-2/3% of the principal amount of the outstanding bonds of all series issued under the Mortgage and which redefine, effective at such time as all bonds of each series of bonds issued under the Mortgage prior to January 1, 1977 are no longer outstanding, the amounts required to be spent by the Company under the Mortgage for the repair, maintenance, renewal and replacement of its property.

PART III

Part III of the Supplemental Indenture dated as of May 1, 1993 is hereby amended in its entirety to read as follows:

"PART III

DESCRIPTION OF BONDS OF THE THIRTY-SIXTH SERIES

Section 1. Bonds of the Thirty-sixth Series shall mature on the date set forth in the form of bond relating hereto hereinbefore set forth, shall bear interest at the rate from time to time borne by the Warrick County Bonds; provided, however, that in no event shall the rate of interest borne by the Bonds of the Thirty-sixth Series exceed 10%. Such interest, payable on the same dates as interest on the Warrick County Bonds, and all bonds of said series shall be designated as hereinbefore in the fifth WHEREAS clause set forth. Both principal of and interest on said bonds shall be payable, to the extent specified in the form of bond hereinabove set forth, in any coin or currency of the United States of America which at the time of payment is legal tender for the payment of public and private debts, at the office or agency of the Company in the Borough of Manhattan, The City of New York, N.Y. Definitive bonds of said series may be issued, originally or otherwise, only as registered bonds without coupons; and they and the Trustee's certificate of authentication shall be substantially in the forms hereinbefore recited, respectively. Definitive registered Bonds of the Thirty-sixth Series may be issued in the denomination of $1,000 and in such other denominations (in multiples of $1,000) as the Board of Directors of the Company shall approve, and execution and delivery to the Trustee for authentication shall be conclusive evidence of such approval. In the manner and upon payment of the charges prescribed in the Indenture, registered bonds without coupons of said series may be exchanged for a like aggregate principal amount of fully registered bonds without coupons of other authorized denominations of the same series, upon presentation and surrender thereof for cancellation to the Trustee at its principal corporate trust office in the Borough of Manhattan, The City of New York, N.Y. However, notwithstanding the provisions of Section 12 of the Indenture, no charge shall be made upon any transfer or exchange of bonds of said series other than for any tax or taxes or other governmental charge required to be paid by the Company. The form of the temporary bonds of said series shall be in substantially the form of the form of registered bond hereinbefore recited with such appropriate changes therein as are required on account of the temporary nature thereof. Said temporary bonds of said series shall be in registered form without coupons, registrable as to principal, and shall be exchangeable for definitive bonds of said series when prepared.

The person in whose name any registered bond without coupons of the Thirty-sixth Series is registered at the close of business on any record date (as hereinbelow defined) with respect to any interest payment date shall be entitled to receive the interest payable on such interest payment date notwithstanding the cancellation of such registered bond upon any transfer or exchange thereof subsequent to the record date and prior to such interest payment date, except if and to the extent the Company shall default in the payment of the interest due on such interest payment date, in which case such defaulted interest shall be paid to the person in whose name such bond is registered either at the close of business on the day preceding the date of payment of such defaulted interest or on a subsequent record date for such payment if one shall have been established as hereinafter provided. A subsequent record date may be established by or on behalf of the Company by notice mailed to the holders of bonds not less than ten days preceding such record date, which record date shall be not more than thirty days prior to the subsequent interest payment date. The term "record date" as used in this Section with respect to any regular interest payment date shall mean the Interest Payment Date (as defined in the County Indenture).

Except as provided in this Section, every registered bond without coupons of the Thirty-sixth Series shall be dated and shall bear interest as provided in Section 10 of the Indenture; provided, however, that so long as there is no existing default in the payment of interest on the bonds, the holder of any bond authenticated by the Trustee between the record date for any interest payment date and such interest payment date shall not be entitled to the payment of the interest due on such interest payment date and shall have no claim against the Company with respect thereto; and provided, further, that, if and to the extent the Company shall default in the payment of the interest due on such interest payment date, then any such bond shall bear interest from the interest payment date to which interest has been paid.

Upon any payment of the principal of and interest on, all or any portion of the Warrick County Bonds, whether at maturity or otherwise or upon provision for the payment thereof having been made in accordance with Section 8.01 of the County Indenture, the Bonds of the Thirty-sixth Series in a principal amount equal to the principal amount of such Warrick County Bonds shall, to the extent of such payment of principal and interest, be deemed paid and the obligation of the Company thereunder to make such payment shall be discharged to such extent and, in the case of the payment of principal, such Bonds of the Thirty-sixth Series shall be surrendered to the Company for cancellation as provided in and subject to the terms of Section 8.02 of the County Indenture. The Trustee may at any time and all times conclusively assume that the obligation of the Company under the Agreement to make payments with respect to the principal of and interest on the County Bonds, so far as such payments at the time have become due, has been fully satisfied and discharged pursuant to the foregoing sentence unless and until the Trustee shall have received a written notice from the County Trustee signed by one of its officers stating (i) the timely payment of principal or interest on the Warrick County Bonds has not been made, (ii) that the Company is in arrears as to the payments required to be made by it to the County Trustee pursuant to the Agreement, and (iii) the amount of the arrearage."

[FORM OF REVERSE OF BOND]

SOUTHERN INDIANA GAS AND ELECTRIC COMPANY

FIRST MORTGAGE BOND, SERIES A 1985 DUE 2015

This bond is one of an issue of First Mortgage Bonds of the Company, issuable in series, and is one of the series designated in the title hereof, all issued and to be issued under and equally secured (except as to any sinking fund established in accordance with the provisions of the Mortgage hereinafter mentioned for the bonds of any particular series) by an Indenture of Mortgage and Deed of Trust, dated as of April 1, 1932, executed by the Company to Deutsche Bank Trust Company Americas, formerly known as Bankers Trust Company, as Trustee (the "Trustee"), as amended and supplemented by indentures supplemental thereto, including without limitation a Supplemental Indenture dated as of July 1, 1985, as particularly supplemented and amended by a Supplemental Indenture dated as of October 1, 2004, to which Indenture as amended and supplemented (herein referred to as the "Mortgage") reference is made for a description of the property mortgaged and pledged, the nature and extent of the security, the rights of the holders of the bonds in respect thereof and the terms and conditions upon which the bonds are secured.

The bonds of this series are issued and to be issued in order to evidence and secure a loan made by the County to the Company pursuant to a Loan Agreement dated as of July 1, 1985, as supplemented and amended. In order to provide moneys to fund such loan, the County has issued the Warrick County Bonds under and pursuant to the County Indenture. Payments made by the Company of principal and interest on the bonds of this series are intended to be sufficient to permit payments of principal and interest to be made on the Warrick County Bonds. Upon certain terms and conditions, moneys held under and pursuant to the County Indenture, including moneys so held from the proceeds of the sale of the Warrick County Bonds or earnings on the investment of such proceeds, or redemption of the Warrick County Bonds shall be credited to or used for the payment of the bonds of this series and to the extent so credited or used shall satisfy a like amount otherwise due hereunder.

The bonds of this series are subject to optional and mandatory redemption, in whole or in part, as the case may be, on each date that Warrick County Bonds are to be redeemed. The principal amount of the bonds of this series to be redeemed on any such date shall be equal to the principal amount of Warrick County Bonds called for redemption on that date. All redemptions of bonds of this series shall be at 100% of the principal amount thereof, plus accrued interest to the redemption date.

If and whenever the Trustee or the Company is notified that an event of default has occurred and is continuing under Section 9.01(e) of the County Indenture, and provided that the principal of all Warrick County Bonds then outstanding and the interest thereon shall have been declared immediately due and payable, then not later than two business days following the occurrence of the foregoing events, the Company shall, upon not less than 30 days' and not more than 45 days' prior written notice given in the manner provided in the Mortgage, call for redemption on a redemption date selected by it not later than 45 days following the date of such notice, all of the bonds of this series then outstanding, and shall on such redemption date redeem the same at a price equal to 100% of the principal amount thereof, together with accrued interest thereon to the redemption date, except that such requirement or redemption shall be deemed to be waived if, prior to the date fixed for such redemption of the bonds of this series, such event of default is waived or cured.

In case a completed default, as defined in the Mortgage, shall occur, the principal of this bond and all other bonds of the Company at any such time outstanding under the Mortgage may be declared or may become due and payable, upon the conditions and in the manner and with the effect provided in the Mortgage. The Mortgage provides that such declaration may in certain events be waived by the holders of a majority in principal amount of the bonds entitled to vote then outstanding.

This bond, subject to the limitations with regard thereto contained in the County Indenture, is transferable as prescribed in the Mortgage by the registered owner hereof in person, or by his duly authorized attorney, at the office or agency of the Company in the Borough of Manhattan, The City of New York, N.Y., upon surrender and cancellation of this bond, and thereupon, a new fully registered bond of the same series for a like principal amount will be issued to the transferee in exchange thereof as provided in the Mortgage, and upon payment, if the Company shall require it, of the charges therein prescribed. The Company and the Trustee may deem and treat the person in whose name this bond is registered as the absolute owner for the purpose of receiving payment of or on account of the principal and interest due hereon and for all other purposes.

As provided in Section 8.02 of the County Indenture, from and after the Release Date (as defined in the County Indenture), the obligations of the Company with respect to this bond shall be deemed to be satisfied and discharged, this bond shall cease to secure in any manner the Company's obligations under the Agreement with respect to the payment of any County Bonds outstanding under the County Indenture, and, pursuant to
Section 8.02 of the County Indenture, the County Trustee shall forthwith deliver this Bond to the Company for cancellation.

The Bonds of this series are issuable as registered bonds without coupons in denominations of $1,000 and authorized multiples thereof. In the manner and upon payment of the charges prescribed in the Mortgage, registered bonds without coupons of this series may be exchanged for a like aggregate principal amount of fully registered bonds without coupons of other authorized denominations of the same series, upon presentation and surrender thereof, for cancellation, to the Trustee at its principal corporate trust office in the Borough of Manhattan, The City of New York, N.Y.

No recourse shall be had for the payment of the principal of or interest on this bond against any incorporator or any past, present or future subscriber to the capital stock, stockholder, officer or director of the Company or of any predecessor or successor corporation, either directly or through the Company or any predecessor or successor corporation, under any rule of law, statute or constitution or by the enforcement of any assessment or otherwise, all such liability of incorporators, subscribers, stockholders, officers and directors being released by the holder or owner hereof by the acceptance of this bond and being likewise waived and released by the terms of the Mortgage.

Pursuant to the Mortgage, the holder or owner of this bond by his acceptance hereof is deemed to have agreed to amendments to the Mortgage which will eventually permit certain amendments to the Mortgage with the consent of the holders of 66-2/3% of the principal amount of the outstanding bonds of all series issued under the Mortgage and which redefine, effective at such time as all bonds of each series of bonds issued under the Mortgage prior to January 1, 1977 are no longer outstanding, the amounts required to be spent by the Company under the Mortgage for the repair, maintenance, renewal and replacement of its property.

In the manner and upon payment of the charges prescribed in the Indenture, registered bonds without coupons of said series may be exchanged for a like aggregate principal amount of fully registered bonds without coupons of other authorized denominations of the same series, upon presentation and surrender thereof for cancellation to the Trustee at its principal corporate trust office in the Borough of Manhattan, The City of New York, N.Y. However, notwithstanding the provisions of Section 12 of the Indenture, no charge shall be made upon any transfer or exchange of bonds of said series other than for any tax or taxes or other governmental charge required to be paid by the Company. The form of the temporary bonds of said series shall be in substantially the form of the form of registered bond hereinbefore recited with such appropriate changes therein as are required on account of the temporary nature thereof. Said temporary bonds of said series shall be in registered form without coupons, registrable as to principal, and shall be exchangeable for definitive bonds of said series when prepared.

The person in whose name any registered bond without coupons of the Twenty-sixth Series is registered at the close of business on any record date (as hereinbelow defined) with respect to any interest payment date shall be entitled to receive the interest payable on such interest payment date notwithstanding the cancellation of such registered bond upon any transfer or exchange thereof subsequent to the record date and prior to such interest payment date, except if and to the extent the Company shall default in the payment of the interest due on such interest payment date, in which case such defaulted interest shall be paid to the person in whose name such bond is registered either at the close of business on the day preceding the date of payment of such defaulted interest or on a subsequent record date for such payment if one shall have been established as hereinafter provided. A subsequent record date may be established by or on behalf of the Company by notice mailed to the holders of bonds not less than ten days preceding such record date, which record date shall be not more than thirty days prior to the subsequent interest payment date. The term "record date" as used in this Section with respect to any regular interest payment date shall mean the Interest Payment Date (as defined in the County Indenture).

Except as provided in this Section, every registered bond without coupons of the Twenty-sixth Series shall be dated and shall bear interest as provided in Section 10 of the Indenture; provided, however, that so long as there is no existing default in the payment of interest on the bonds, the holder of any bond authenticated by the Trustee between the record date for any interest payment date and such interest payment date shall not be entitled to the payment of the interest due on such interest payment date and shall have no claim against the Company with respect thereto; and provided, further, that, if and to the extent the Company shall default in the payment of the interest due on such interest payment date, then any such bond shall bear interest from the interest payment date to which interest has been paid.

Upon any payment of the principal of and interest on, all or any portion of the Warrick County Bonds, whether at maturity or otherwise or upon provision for the payment thereof having been made in accordance with Section 8.01 of the County Indenture, the Bonds of the Twenty-sixth Series in a principal amount equal to the principal amount of such Warrick County Bonds shall, to the extent of such payment of principal and interest, be deemed paid and the obligation of the Company thereunder to make such payment shall be discharged to such extent and, in the case of the payment of principal, such Bonds of the Twenty-sixth Series shall be surrendered to the Company for cancellation as provided in and subject to the terms of Section 8.02 of the County Indenture. The Trustee may at any time and all times conclusively assume that the obligation of the Company under the Agreement to make payments with respect to the principal of and interest on the County Bonds, so far as such payments at the time have become due, has been fully satisfied and discharged pursuant to the foregoing sentence unless and until the Trustee shall have received a written notice from the County Trustee signed by one of its officers stating (i) the timely payment of principal or interest on the Warrick County Bonds has not been made, (ii) that the Company is in arrears as to the payments required to be made by it to the County Trustee pursuant to the Agreement, and (iii) the amount of the arrearage."
