QUESTAR CORPORATION AND SUBSIDIARIES
NOTES ACCOMPANYING CONSOLIDATED FINANCIAL STATEMENTS
June 30, 2003
(Unaudited)
Note 1 - Basis of Presentation
The interim financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair presentation of the results of operations for the interim periods presented. All such adjustments are of a normal recurring nature. Due to the seasonal nature of the gas distribution business, the results of operations for the three-, six- and twelve-month periods ended June 30 are not necessarily indicative of the results that may be expected for the year ending December 31, 2003. The impact of abnormal weather on gas distribution earnings is partially reduced by the operation of a weather-normalization adjustment. The straight fixed-variable rate design, which allows for recovery of substantially all fixed costs in the demand or reservation charges, reduces the earnings impact of weather conditions on gas transportation and storage operations. For further information please refer to the financial statements and footnotes thereto included in the Annual Report on Form 10-K for the year ended December 31, 2002 that was filed by Questar Corporation (Questar or the Company).
Note 2 - Utah Supreme Court Order in Questar Gas Carbon Dioxide Case
The Utah Supreme Court issued an order reversing a decision made by the Public Service Commission of Utah (PSCU) in August of 2000 concerning certain processing costs incurred by Questar Gas Company (Questar Gas). The court ruled that the PSCU did not comply with its responsibilities and regulatory procedures when approving a stipulation in Questar Gas's general rate case filed in December of 1999. The stipulation permitted Questar Gas to collect $5 million per year in rates to recover costs incurred to reduce the level of carbon dioxide in gas volumes delivered to customers. The Committee of Consumer Services, a Utah state agency, appealed the PSCU's decision because the PSCU did not address whether or not the costs were prudently incurred. The Supreme Court heard the appeal in June of 2003 and issued an order on August 1, 2003.
The Committee of Consumer Services had argued that the costs of carbon dioxide removal should have been borne by nearby gas producers, not Questar Gas customers. The Committee argued that Questar Pipeline Company (Questar Pipeline), a Questar Gas affiliate, should have sought Federal Energy Regulatory Commission (FERC) approval to modify its pipeline transportation tariff to force gas producers in central Utah to remove carbon dioxide from the gas before delivery for transport on Questar Pipeline.
As a result of the Supreme Court's order, Questar Gas recorded a $22 million liability for a potential refund to gas distribution customers. The liability reflects revenue received for processing costs from June of 1999 through June of 2003. This charge reduces Questar's consolidated net income by $13.6 million or $.16 per diluted share. Going forward, for the safety of Questar Gas's customers, the Company intends to continue operating the plant to remove carbon dioxide from the gas stream. The cost for the second half of 2003 will be approximately $1.6 million after tax or $.02 per diluted share. Thereafter, annual costs will be approximately $3.2 million after tax or $.04 per diluted share. Recording the liability did not have a material impact on credit, cash or liquidity of Questar or Questar Gas.
The processing plant was constructed and is operated by Questar Transportation Services, a subsidiary of Questar Pipeline. Questar Gas determined that contracting with Questar Transportation Services was the lowest cost alternative. The net book value of the plant was approximately $17.4 million as of June 30, 2003.
Questar Gas believes that it acted prudently and in the best interests of its customers to incur the processing costs. It will pursue legal and regulatory avenues to recover processing costs incurred historically and to collect such costs in future rates.
Note 3 - New Accounting Standard
Cumulative Effect of Accounting Change -"Accounting for Asset Retirement Obligations"
On January 1, 2003, Questar adopted Statement of Financial Accounting Standards 143 (SFAS 143) "Accounting for Asset Retirement Obligations" and recorded a $5.6 million after tax charge ($.07 per diluted share) for the cumulative effect of this accounting change. SFAS 143 addresses the financial accounting and reporting of the fair value of legal obligations associated with the retirement of tangible long-lived assets. The new standard requires the Company to estimate a fair value of abandonment costs and to capitalize and depreciate those costs over the life of the related assets. The asset retirement obligation is adjusted to its present value each period through an accretion process using a credit-adjusted risk-free interest rate. Both the accretion expense associated with the liability and the depreciation associated with the capitalized abandonment costs are non-cash expenses until the asset is retired. The adoption of SFAS 143 caused Questar to change the accounting method for plugging and abandonment costs associated with gas and oil wells and certain other properties. SFAS 143 was applied retroactively to prior years to determine the cumulative effect through December 31, 2002. Questar Gas recorded a regulatory asset as of June 30, 2003, amounting to $7.4 million representing a retroactive charge for the abandonment costs associated with gas wells operated on its behalf by Wexpro Company (Wexpro). The regulatory asset will be reduced as the gas wells are plugged and abandoned.
The accretion expense in the first six months of 2003 amounted to $1.0 million. An additional $700,000 of accretion costs were capitalized in a regulatory asset. If the new method of accounting for plugging and abandonment costs had been in effect for the first half of 2002, the pro forma accretion expense would have been $900,000.

Goodwill in each line of business at June 30, 2003 was unchanged from the balances at December 31, 2002.
Note 5 - Earnings Per Share
Basic EPS is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the accounting period. Diluted EPS includes the potential increase in the number of outstanding shares that could result from the exercise of stock options; which is the reason for the difference between the number of basic and diluted average shares outstanding.
In the first half of 2003, the number of basic common shares increased 770,000 as a result of issuances under several plans. These plans include the Long-Term Stock Incentive Plan, the Dividend Reinvestment and Stock Purchase Plan, and the Employee Investment Plan.

Note 6 - Stock-based compensation
The Company accounts for employee stock-based compensation using the intrinsic value method prescribed by Accounting Principles Board (APB) Opinion 25, "Accounting for Stock Issued to Employees" and related interpretations. Under this method, no compensation expense is recorded by the Company for stock options granted because the exercise price of those options is equal to the market price of the Company's common stock on the date of grant. A table showing pro forma income as if the options were expensed follows:

Note 8 - Financing
On January 24, 2003, Questar Gas issued $40 million of medium-term notes with an effective interest rate of 5.02% and a ten-year life. The proceeds were used to redeem $41 million of debt with a coupon rate of 8.4%. Questar Gas paid a $1.7 million call premium. This issue completed a Form S-3 shelf registration for issuance of up to $100 million of medium-term notes filed by Questar Gas in the third quarter of 2001.
On February 27, 2003, Questar Gas filed a shelf registration statement for the issuance of up to $70 million of medium-term notes. In March 2003, Questar Gas sold $70 million of 15-year notes with a coupon rate of 5.31%. On April 24, 2003, proceeds from the offering were used to redeem $64 million of higher-cost debt issued in 1992 and 1993 with a weighted-average interest rate of 8.11%. Questar Gas paid a call premium of $2.6 million.
Questar has a shelf registration to issue up to $400 million of common equity or debt convertible into common stock. While it is the Company's intention to issue no more than $200 million in securities initially, the filing registered both the convertible debt that could be issued and the subsequent common stock that would be issued in a convertible debt offering. Currently, there are no plans to issue securities under this shelf registration.
Note 9 - Investment in Unconsolidated Affiliates
Questar, indirectly through subsidiaries, has interests in partnerships accounted for on the equity basis. These entities are engaged primarily in the gathering and/or processing of natural gas. The entities do not have debt obligations with third-party lenders. Questar uses the equity method to account for investments in affiliates in which it does not have control. The principal affiliates and Questar's ownership percentage as of June 30, 2003 were: Rendezvous Gas Services LLC, a limited liability corporation, (50%) and Canyon Creek Compression Co., a general partnership (15%). Gathering and processing results for the 2002 period presented included an affiliate's 50% interest in Blacks Fork Processing. Since the fourth quarter of 2002, Blacks Fork Processing is 100% owned by an affiliate of Questar. TransColorado Pipeline, which was sold in the fourth quarter of 2002, and Overthrust Pipeline, of which affiliates of Questar own 100% since the fourth quarter of 2002, comprised the transportation businesses.

Second quarter and first half comparison of 2003 with 2002
Exploration and Production (E&P)
Higher selling prices for natural gas, oil and natural gas liquids in the second quarter and first half of 2003 more than offset the lower production volumes resulting in increased revenues. Realized natural gas prices, net to the well, increased 44% in the second quarter and first half of 2003 when compared with the same periods of 2002. Realized natural gas prices in the second quarter of 2003 exceeded first quarter 2003 prices by 4%. The higher prices reflect sustained demand for natural gas combined with the startup of the expansion of the Kern River pipeline owned by MidAmerican Energy.
Roughly two-thirds of the Company's 2003 nonregulated production came from properties located in the Rocky Mountains. Rockies basis differential, measured against prices at Henry Hub, averaged more than $2.50 per MMBtu in the first quarter of 2003 and dropped to roughly $1.25 per MMBtu in the second quarter. As of August 2003, the differential was $.75 to $.80 per MMBtu, higher than the historical levels of $.40 to .60 per MMBtu. A significant factor in the shrinking basis differential appears to be the 900 MMcf per day expansion of Kern River pipeline, which began service on May 1, 2003. The expansion represents approximately a 20% increase in export capacity out of the western Rockies. Realized prices received for QMR's Rockies gas production were 68% higher in the second quarter of 2003 compared with the 2002 quarter. A year ago, QMR voluntarily shut-in 1.5 Bcfe of production when Rockies spot prices fell below $1 per MMBtu. Realized Midcontinent gas prices were 24% higher in the second quarter of 2003 when compared with the second quarter for 2002.
Prices received for nonregulated oil and natural gas liquids increased 9% in the second quarter and 20% in the first half of 2003 when compared with the corresponding periods of 2002.
Production, measured in natural gas-equivalents, decreased 12% in the quarter-to-quarter comparison and 8% in the first half comparison. The decline resulted from the sale of QMR's Canadian E & P subsidiary, San Juan E & P properties and other non-core, producing properties in the second half of 2002 and federal drilling restrictions in the Pinedale area from November to May.
Approximately 67% of first half 2003 nonregulated gas production was hedged or presold at an average price of $3.32 per Mcf, net to the well. This resulted in a $26.0 million reduction in gas revenues when compared with the prices received from the physical sales transactions. Approximately 53% of first half 2003 nonregulated oil production was hedged or presold at an average price of $21.80 per bbl, net to the well, resulting in a $6.0 million reduction in oil revenues. In the first half of 2002, hedging activities added $17.9 million of revenues.
Lifting costs per Mcfe were higher in the 2003 periods presented due to a higher production tax component driven up by higher selling prices. The lease operating expense component of lifting cost was lower in the 2003 periods after the 2002 sale of higher cost Canadian properties. General and administrative costs were higher in the 2003 periods due primarily to increased employee benefits and property insurance costs. A second quarter and first half comparison of operating costs on an Mcfe basis is shown in the table below.

Wexpro Earnings
Wexpro's net income increased $600,000 in the second quarter of 2003 and first half of 2003 when compared with the corresponding periods of 2002 due to higher selling prices for oil, capitalizing interest and lower debt expense. Wexpro's first quarter 2003 results included a $600,000 after tax charge for the cumulative effect of an accounting change. In the second quarter of 2003, Wexpro recorded approximately $900,000 of capitalized financing costs (AFUDC) on a well spudded in 2000. The net investment base was lower at June 30, 2003 when compared to June 30, 2002. Depreciation expense exceeded capital spending for commercial wells in the first half of 2003. Wexpro earns a specified after-tax return of 19 to 20% on its net investment in commercial wells drilled on behalf of Questar Gas.
Gas Gathering and Gas and Oil Marketing
Net income from gathering operations was higher in the second quarter and first half of 2003 when compared with the 2002 periods due to increased volumes of gas gathered and higher margins. Higher gas and oil prices resulted in an increase in gas and oil marketing revenues and margins in the first half of 2003 compared with the same period in 2002. The margin, which represents revenues less the costs to purchase gas and oil and transport gas, increased from $7.2 million in the first half of 2002 to $8.2 million in the first half of 2003. In addition, the QMR's share of earnings in Rendezvous Gas Services increased by $600,000 after tax in the second quarter of 2003 and by $1 million in the first half of 2003. Rendezvous provides gathering and processing services for the Pinedale and Jonah producing areas.
Comparison of 12 months ended June 30, 2003 and 2002
Higher selling prices for gas, oil and natural gas liquids were responsible for a 22% increase in revenues when comparing the 12 months ended June 30, 2003 with the corresponding period of 2002. Production, measured in natural gas equivalents was 4% lower in the 2003 period due to sales of non-core producing properties. A majority of the asset sales took place in the fourth quarter of 2002.
Lifting costs per Mcfe increased by 1% in the 12-month comparison due to higher production taxes that more than offset a reduction in lease operating expenses. Lower amounts spent on contracted services, such as trucking and pumping were responsible for the lower lease operating expenses. General and administrative costs were higher in 2003 due to higher employee benefit costs and property insurance costs. A comparison of the information for the 12 months ended June 30, 2003 and 2002 on an Mcfe basis is shown in the table below.

Revenues less cost of natural gas sold (margin)
Questar Gas's margin was higher in the 2003 periods presented compared with the 2002 periods due to a general rate increase, customer additions and higher usage per customer. Effective December 30, 2002, the Public Service Commission of Utah (PSCU) issued an order approving an $11.2 million general rate increase for Questar Gas using an 11.2% return on equity. The rate increase also reflects year-end 2002 usage per customer and costs. The number of customers increased 19,614 or 2.7% in the year over year comparison. Temperature adjusted usage per customer grew by 6% in the second quarter and 3% in the first half of 2003 compared with the same periods in 2002. This positive change in usage per customer is not expected to continue. Questar Gas recently received PSCU approval to pass-through a 25% increase in natural gas costs in rates beginning July 1, 2003.
The margin for the 12-months ended June 30, 2003 was higher when compared with the corresponding period of 2002 due to several factors in addition to those discussed above. The 2003 period benefited from an August 2002 one-time recovery of $3.8 million of gas costs previously denied. The PSCU order allowing the recovery was later reversed by a Utah Supreme Court ruling dated August 1, 2003. In addition, the PSCU authorized Questar Gas to recover the gas cost portion of bad debt expense in its pass through gas costs. Starting in 2003, the Utah general rate case required recording contributions in aid of construction as a reduction of rate base rather than in revenues.
The weather-normalization adjustment (WNA) mitigates the financial effect of temperatures that are either colder or warmer than normal. Generally, under the WNA customers pay for non-gas costs based on normal temperatures.
Gas volumes delivered to industrial customers were lower in the 2003 periods presented due to decreased gas usage for generation of electricity and in manufacturing processes.
Expenses
Operating and maintenance expenses were higher in the 2003 periods presented when compared to the same periods in 2002 due primarily to higher labor-related costs. Labor-related expenses have increased primarily because of higher costs of pension and benefit programs and less capitalization of labor costs. Higher depreciation expense in the first half of 2003 reflects increased investment in computer equipment and software, which are depreciated over a shorter life than assets placed in the ground.
The Utah Supreme Court issued an order reversing decisions made by the PSCU in August of 2000 and August of 2002. The PSCU originally permitted Questar Gas to collect $5 million per year to recover costs incurred to process certain gas volumes delivered to customers. In August 2002, the PSCU allowed an additional $3.8 million of recovery from a previous period. As a result of the order, Questar Gas recorded a $22 million liability reflecting a potential refund of processing costs collected in rates from June of 1999 through June of 2003.

Revenues
Revenues were higher in the 2003 periods compared with the 2002 periods due primarily to increased transportation capacity and accompanying contracted service. Questar Pipeline's total transportation volumes for the second quarter, first half and 12 months ended June 30, 2003 were higher than the volumes reported in the corresponding periods of 2002. Total firm daily demand was 1,518,000 Dth in the first half of 2003 compared with 1,385,000 Dth in the first half of 2002. Higher volumes were primarily the result of the startup of the eastern segment of the Questar Southern Trails pipeline mid-year 2002. The eastern segment of Southern Trails has a capacity of 80,000 Dth daily, which is full-contracted through 2006. The Company expanded its transportation service to the Kern River pipeline beginning in May 2003. Deliveries increased by an average of 155,000 Dth per day. Deliveries, transported on Overthrust pipeline, accounted for about 55% of the increase.
Other increases in 2003 revenues were the result of a new park and loan storage service started in 2002, increased gas gathering volumes, and higher selling prices for natural gas liquids extracted from the gas stream.
Expenses
The impact on earnings from higher revenues was offset by higher operating expenses. Questar Pipeline, in the second quarter and first half of 2003 compared with the 2002 periods, because of pipeline expansion, higher costs for employee benefits, less capitalization of labor because of reduced construction activity and increased insurance and pipeline inspection costs. Questar Pipeline, through its subsidiaries, has not yet realized the full benefit of consolidating Overthrust Pipeline because of a lag in revenues between the expiring old transportation contracts and the sale of replacement capacity. AFUDC, the capitalization of financing costs as a part of project costs, was significantly lower in 2003. AFUDC is a component of interest and other income on the income statement. The higher level of investment in pipeline projects of past years resulted in higher depreciation expenses and property taxes in the 2003 periods.
Lower debt and legal expenses in 2002 were primarily the result of the resolution of the TransColorado lawsuit and the sale of the company's 50% interest in TransColorado in the fourth quarter of 2002.
Consolidated Operations Results After Operating Income
Interest and other income was lower in the second quarter and first half of 2003 due to 2002 non-core property sales, a lawsuit settlement, and lower AFUDC. Pretax gains from property sales amounted to $47,000 in the first half of 2003 and $5.4 million in the first half of 2002. The sale of a Canadian E&P subsidiary, San Juan E&P properties and other E&P properties accounted for pretax gains of $38.3 million in the 12 months ended June 30, 2003. QMR settled a lawsuit in the second quarter of 2002 resulting in a pretax gain of $4.5 million.
Rendezvous Gas Services' income increased in the 2003 periods presented due to higher volumes and prices. A QMR subsidiary is a 50% partner in Rendezvous, which provides gathering and processing services for the Pinedale and Jonah producing areas of western Wyoming. Questar Pipeline's share of the TransColorado partnership in the trailing 12 months was a pretax profit of $4.8 million in 2003 compared with a $1.7 million pretax profit for the 2002 period.
Lower debt balances and lower variable interest rates resulted in lower debt expenses in the second quarter and first half of 2003 when compared with the 2002 periods. In 2002, the Company applied the proceeds of approximately $250 million from asset sales to repay debt. In addition, Questar Gas replaced higher cost debt with lower cost debt in 2003.
The effective income tax rate for the first half was 37.4% in 2003 and 35.8% in 2002. An income tax credit associated with non-conventional fuels expired December 31, 2002. The Company recognized $3.1 million of non-conventional fuel tax credits in the first half of 2002, including QMR's $2.2 million portion of the credits.
Cumulative Effect of Changes in Accounting Methods
On January 1, 2003, the Company adopted a new accounting rule, SFAS 143, "Accounting for Asset Retirement Obligations" and recorded a cumulative effect that reduced net income by $5.6 million or $.07 per diluted common share. Accretion expense associated with SFAS 143 amounted to $1.0 million in the first half of 2003. A year earlier, the Company adopted the provisions of SFAS 142, "Goodwill and Other Intangible Assets" that resulted in impairment of the goodwill acquired by Consonus. The Company wrote off $17.3 million of goodwill, of which, $15.3 million or $.19 per diluted common share was attributed to Questar InfoComm's share and reported as a cumulative effect of a change in accounting for goodwill. The remaining $2.0 million was attributed to minority shareholders.
Liquidity and Capital Resources
Operating Activities
Net cash provided from operating activities in the first half of 2003 was $38.3 million less than was provided during the first half of 2002. Lower cash flows from accounts receivable and purchased-gas adjustments due to timing differences and higher energy prices were responsible for the decrease. Higher gas and oil prices also resulted in $9.2 million of margin calls as of June 30, 2003. Margin calls are interest-bearing deposits with counterparties to energy hedging transactions.
Investing Activities
A comparison of capital expenditures for the first half of 2003 and 2002 plus an estimate for calendar year 2003 is presented below. Accelerated development of the Company's interest in the Pinedale Anticline of Wyoming and related operations is a significant portion of 2003 expenditures. Forecasted 2003 capital expenditures for Corporate and other operations includes $13 million that has not been committed to a specific project.

Financing Activities
Net cash flow provided from operating activities was more than sufficient to fund capital expenditures in the first half of 2003. The excess cash flow plus the proceeds from issuing $110 million of long-term fixed rate debt were used to repay debt. Questar Gas redeemed $105 million of debt in the first half of 2003. QMR paid down its revolving debt by $145 million. Total debt as a percentage of capitalization was 47% at June 30, 2003 compared with 57% a year earlier. The Company used proceeds from asset sales in 2002 to reduce debt balances.
The Company's lines-of-credit capacity as of July 31, 2003 was $200 million. Short-term debt amounted to $58.5 million of commercial paper at June 30, 2003. A year earlier, short-term debt was comprised of $247.5 million of commercial paper and $100 million of borrowings from banks.
Item 3. Quantitative and Qualitative disclosures About Market Risk
QMR's primary market-risk exposures arise from commodity-price changes for natural gas, oil and other hydrocarbons and changes in interest rates. A QMR subsidiary has long-term contracts for pipeline capacity for several years and is obligated for transportation services with no guarantee that it will be able to recover the full cost of these transportation commitments.
QMR bears a majority of the risk associated with commodity-price changes and uses gas- and oil-price-hedging arrangements in the normal course of business to limit the risk of adverse price movements. However, these same arrangements typically limit future gains from favorable price movements. The hedging contracts exist for a significant share of QMR-owned gas and oil production and for a portion of gas-and oil-marketing transactions.
Commodity-Price Risk Management
QMR has established policies and procedures for managing commodity-price risks through the use of derivatives. The primary objectives of natural gas- and oil-price hedging are to support QMR's earnings targets, and to protect earnings from downward movements in commodity prices. The volume of production hedged and the mix of derivative instruments employed are regularly evaluated and adjusted by management in response to changing market conditions and reviewed periodically by QMR's Board of Directors. It is QMR's policy to hedge up to 75% of the current year's proved-developed-production by March in the current year, at or above selling prices that support its earnings, targets, cash flow and return on capital. QMR will add incrementally to these hedges to reach forward beyond the current year when price levels are attractive. QMR does not enter into derivative arrangements for speculative purposes and does not hedge undeveloped reserves. Hedges are matched to equity gas and oil production, thus qualifying as cash flow hedges under the accounting provisions of SFAS 133 as amended and interpreted. Gas hedges are structured as fixed-price swaps into regional pipelines locking in basis and hedge effectiveness.
Management's attention has been focused on improving Rockies gas prices by hedging 18.8 Bcf of forecasted Rockies second half 2003 proved-developed-production at an average price of $3.38 per Mcf, net to the well.
A summary of QMR's gas- and oil-price hedging positions for equity gas and oil production as of July 31, 2003, is below. Net to the well means that prices are fixed at a delivery point into a regional pipeline and reduced by gathering costs.
	Rocky			Midcontinent							Total			Rocky			Midcontinent					Total

				Gas (in Bcf)										Average price per Mcf, net to the well
Second half of 2003	18.8			6.9							25.7			$3.38			$4.00					$3.54

				Oil (in MBbl)										Average price per Bbl, net to the well
Second half of 2003	460			92							552			$21.68			$22.38					$21.80
QMR held gas- and oil-price hedging contracts covering the price exposure for about 127.3 million dth of gas and 552,000 bbl of oil as of June 30, 2003. The contracts existed for both equity gas and oil and marketing transactions. A year earlier QMR hedging contracts covered 89.6 million dth of natural gas and 2.1 million bbl of oil. QMR does not hedge the price of natural gas liquids.
A summary of the activity for the fair value of hedging contracts for the six months ended June 30, 2003, is below. The calculation is comprised of the valuation of financial and physical contracts.

Interest-Rate Risk Management
As of June 30, 2003, Questar had $55 million of variable-rate long-term debt and $950.2 million of fixed-rate long-term debt. In addition, the Company has $58.5 million of variable-rate short-term debt at June 30, 2003. Generally, the imbedded cost of fixed-rate debt exceed rates currently available in the market. The book value of variable-rate long-term debt approximates fair value.
OTHER INFORMATION
Western Segment of Questar Southern Trails Pipeline
The Company has thus far been unsuccessful in its efforts to secure long-term contracts required to place the western segment of the Southern Trails pipeline into service. The western segment extends from the California-Arizona border to Long Beach, California. In June 2003, the Company requested and received prompt FERC approval of an 18-month extension of its construction certificate for this pipeline. Questar Southern Trails Pipeline, a subsidiary of Questar Pipeline, is actively seeking customers willing to enter into long-term gas transportation contracts necessary to place the pipeline into service. The Company is also considering selling this pipeline, and has received non-binding offers from several interested parties. A decision to place in-service or sell the pipeline is expected by the end of 2003. Questar Southern Trails Pipeline's investment in the western segment is approximately $52 million.
Purchased-Gas Cost Filings
Effective July 1, 2003, the PSCU approved a $146.4 million pass-on increase in annual gas costs for Utah customers. The Public Service Commission of Wyoming granted Questar Gas permission to pass-on a $6.8 million increase in gas costs to Wyoming customers also effective July 1, 2003. The increased gas costs were attributed to a forecast of higher gas prices in the Rockies. Pass-on rate increases or decreases result in dollar for dollar adjustments of revenues and gas costs without affecting the earnings of Questar Gas.
FERC - Notice of Proposed Rulemaking (NOPR)
The FERC issued a NOPR on Quarterly Financial Reporting and Revision to the Annual Reports. The NOPR, among other issues, requires a new quarterly filing of financial statements matching the deadlines imposed by the SEC. The FERC has not previously required quarterly statements.
FERC - Rule on Affiliate Relations
The FERC is expected to issue final rules requiring pipelines to comply with certain "nondiscriminatory" standards when dealing with energy company affiliates including local distribution companies. At the current time, local distribution companies (LCDs) such as Questar Gas that do not engage in unregulated gas sales are exempt from the FERC's marketing affiliate regulations. Questar Regulated Services believes that the current exemption should be continued, but the FERC has not yet made a decision on whether affiliate rules should be expanded to include gas LDCs such as Questar Gas. A FERC decision to extend energy affiliate rules to include LDCs could have adverse consequences for Questar. Questar Pipeline and Questar Gas realize significant cost savings by sharing the cost of administrative, engineering, gas control, technical, accounting, legal, and other regulatory services.
Recent Accounting Developments
In January 2003, Financial Accounting Standard Board Interpretation 46 (FIN 46) was issued to address perceived weaknesses in accounting for entities commonly known as special-purpose or off-balance-sheet entities, but the guidance applies to a larger population of entities. FIN 46 provides guidance for identifying the party with a controlling financial interest resulting from arrangements or financial interests rather than from voting interests. FIN 46 defines the term "variable interest entity" (or "VIE") and is based on the premise that if a business enterprise has a controlling financial interest in a VIE, the assets, liabilities, and results of the activities of the VIE should be included in the consolidated financial statements of the business enterprise. We are currently studying the provisions of FIN 46. Based upon our initial interpretation of FIN 46, we do not believe that this guidance will have a material effect on our financial statements.

Item 4. Controls and Procedures
a. Evaluation of Disclosure Controls and Procedures. The Company's Chief Executive Officer and Chief Financial Officer have evaluated the effectiveness of the Company's disclosure controls and procedures (as such term is defined in Rules 13a-14(c) and 15d-14(c) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) as of a date within 90 days prior to the filing date of this quarterly report (the "Evaluation Date"). Based on such evaluation, such officers have concluded that, as of the Evaluation Date, the Company's disclosure controls and procedures are effective in alerting them on a timely basis to material information relating to the Company, including its consolidated subsidiaries, required to be included in the Company's reports filed or submitted under the Exchange Act.
b. Changes in Internal Controls. Since the Evaluation Date, there have not been any significant changes in the Company's internal controls or in other factors that could significantly affect such controls.

Part II OTHER INFORMATION
Item 1. Legal Proceedings.
The Public Service Commission of Utah (the PSCU) has set a date of August 18, 2003 for a scheduling conference involving Questar Gas Company's general rate case in response to the receipt of an order from the Supreme Court of Utah. Questar Gas Company (Questar Gas), a wholly-owned indirect subsidiary of Questar Corporation (Questar or the Company), both filed Current Reports on Form 8-K describing the Utah court's order that was issued on August 1, 2003. The Utah court ruled that the PSCU did not comply with its responsibilities and regulatory procedures when approving a stipulation in Questar Gas's general rate case in August of 2000. The stipulation permitted Questar Gas to reflect $5 million in rates per year to recover processing costs to remove carbon dioxide from gas volumes delivered to it customers.
The Committee of Consumer Services, a Utah state agency whose appeal was responsible for the order described above, filed a petition with the PSCU on August 8, 2003. This petition requests the PSCU to set new rates for Questar Gas effective September 1, 2003, to reflect a refund credit plus interest associated with historic processing costs and to eliminate the recovery of future processing costs.
Questar and Questar Gas continue to strongly believe that Questar Gas acted prudently and in the best interests of customers when it incurred the processing costs. Pending the outcome of the PSCU's actions, the Company and Questar Gas are recording an after-tax reduction of $13.6 million in their respective financial statements for the three- and six-month periods ending June 30, 2003.

        SECTION 51.  (a)  Voluntary Indemnification.  Unless otherwise provided in the Articles of Incorporation, the Corporation shall indemnify any individual made a party to a proceeding because he is or was a director of the Corporation, against liability incurred in the proceeding, but only if the Corporation has authorized the payment in accordance with the applicable statutory provisions [Sections 16-10a-902 and 16-10a-904 of Utah's Revised Business Corporation Act] and a determination has been made in accordance with the procedures set forth in such provision that the director conducted himself in good faith; that he reasonably believed that his conduct, if in his official capacity with the Corporation, was in its best interests and that his conduct, in all other cases, was at least not opposed to the Corporation's best interests; and that he had no reasonable cause to believe his conduct was unlawful in the case of any criminal proceeding.

            (b)  The Corporation shall not indemnify a director in connection with a proceeding by or in the right of the Corporation in which the director was adjudged liable to the Corporation or in connection with any other proceeding charging improper personal benefit to him, whether or not involving action in his official capacity, in which he was adjudged liable on the basis that personal benefit was improperly received by him.

            (c)  Indemnification permitted under paragraph (a) in connection with a proceeding by or in the right of the Corporation is limited to reasonable expenses incurred in connection with the proceeding.

            (d)  If a determination is made, using the procedures set forth in the applicable statutory provision, that the director has satisfied the requirements listed herein and if an authorization of payment is made, using the procedures and standards set forth in the applicable statutory provision, then, unless otherwise provided in the Corporation's Articles of Incorporation, the Corporation shall pay for or reimburse the reasonable expenses incurred by a director who is a party to a proceeding in advance of the final disposition of the proceeding if the director furnishes the Corporation a written affirmation of his good faith belief that he has satisfied the standard of conduct described in this Section, furnishes the Corporation a written undertaking, executed personally or on his behalf, to repay the advance if it is ultimately determined that he did not meet the standard of conduct (which undertaking must be an unlimited general obligation of the director, but need not be secured and may be accepted without reference to financial ability to make repayment); and if a determination is made that the facts then known of those making the determination would not preclude indemnification under this Section.

            (e)  Mandatory Indemnification.  Unless otherwise provided in the Corporation's Articles of Incorporation, the Corporation shall indemnify a director or officer of the Corporation who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which he was a party because he is or was a director or officer of the Corporation against reasonable expenses incurred by him in connection with the proceeding.

            (f)  Court-Ordered Indemnification.  Unless otherwise provided in the Corporation's Articles of Incorporation, a director or officer of the Corporation who is or was a party to a proceeding may apply for indemnification to the court conducting the proceeding or to another court of competent jurisdiction. The court may order indemnification if it determines that the director or officer is entitled to mandatory indemnification as provided in this Section and applicable law, in which case the court shall also order the Corporation to pay the reasonable expenses incurred by the director or officer to obtain court-ordered indemnification. The court may also order indemnification if it determines that the director or officer is fairly and reasonably entitled to indemnification in view of all the relevant circumstances, whether or not the director or officer met the applicable standard of conduct set forth in this Section and applicable law. Any indemnification with respect to any proceeding in which liability has been adjudged in the circumstances described in paragraph (b) above is limited to reasonable expenses.

            (g)  Unless otherwise provided in the Corporation's Articles of Incorporation, an officer, employee, or agent of the Corporation shall have the same indemnification rights provided to a director by this Section. The Board of Directors may also indemnify and advance expenses to any officer, employee, or agent of the Corporation, to any extent consistent with public policy as determined by the general or specific purpose of the Board of Directors.

            (h)  Insurance.  The Corporation may purchase and maintain liability insurance on behalf of a person who is or was a director, officer, employee, fiduciary, or agent or the Corporation, or who, while serving as a director, officer, employee, fiduciary, or agent of the Corporation, is or was serving at the request of the Corporation as a director, officer, partner, trustee, employee, fiduciary or agent of another foreign or domestic corporation, other person, of an employee benefit plan, or incurred by him in that capacity or arising from his status as a director, officer, employee, fiduciary, or agent, whether or not the Corporation has the power to indemnify him against the same liability under applicable law.

A Retired Participant cannot receive benefits under the Plan during any period that his monthly benefits from the Retirement Plan are suspended.
5.	Supplemental Retirement Benefits.
A Participant who satisfies the eligibility requirements described above shall be eligible to receive Supplemental Retirement Benefits under the Plan. The first payment of Supplemental Retirement Benefits will be due on the first day of the month following retirement, and payments will continue on the first day of each month thereafter so long as the Retired Participant is alive or so long as his/her surviving spouse is entitled to receive monthly benefits under the Retirement Plan. (The Retired Participant's surviving spouse must have been married to the Participant at date of his/her retirement.)
The monthly Supplemental Retirement Benefit shall equal the monthly benefit that would have been payable to or on behalf of a Retired Participant under the Retirement Plan if the limitation on annual benefits imposed by Section 415 of the Code and if the limitation on annual compensation as defined in Section 401(a)(17) of the Code were not applicable, and if the Retired Participant had not voluntarily chosen to defer any compensation under the terms of the Questar Corporation Deferred Share Make-Up Plan, less the monthly benefits payable from the Retirement Plan and the EIRP (if any).
Except as provided in Section 7, the monthly Supplemental Retirement Benefit payable to or on behalf of the Retired Participant as determined herein shall be paid in the same form as such Retired Participant's benefits are payable under the Retirement Plan. Any monthly Supplemental Retirement Benefits payable to the Retired Participant's surviving spouse shall be reduced by the monthly benefits payable to such surviving spouse under the Retirement Plan and the EIRP (if any).
6.	Lump Sum Election.
A Participant has a one-time election to receive the present value of his Supplemental Retirement Benefit in a lump sum. The Participant shall make this election at least one year prior to retirement. The present value shall be calculated using a standard mortality table referred to as the "83 Group Annuity Mortality Table" and 80 percent of the six-month average rate for 30-year Treasury bond (prior to the Participant's retirement). When making this election, the Participant shall also indicate when the lump-sum payment shall be made and if it is to be made in more than one installment. The full amount of any lump-sum payment, together with credited interest, must be paid within five years of the Participant's retirement. Any deferred
payouts of lump-sum payments shall be credited with interest calculated at a monthly rate using the appropriate 30-year Treasury bond quoted in the Wall Street Journal on the first business day of each month. (The appropriate 30-year Treasury bond shall be the bond that has one closest to maturity date (by month) preceding the date on which the interest is to be credited.) Any lump-sum payments that are not deferred shall be paid on the first business day of the month following the Participant's retirement date or as soon thereafter as is administratively practicable. If the Participant fails to make an election at least one year prior to retirement, the Participant shall receive monthly benefits.
Notwithstanding this provision, a Participant who has not been advised that he may receive Supplemental Retirement Benefits and has not received an opportunity to make a lump-sum election at least one year prior to his retirement shall receive any Supplemental Retirement Benefits in one lump-sum payment. The calculation of this benefit and the payment of this benefit shall be made in accordance with the provisions of this Section.
7.	Funding.
The Supplemental Retirement Benefits payable under the Plan shall be paid by the Company and Participating Corporations out of general assets. In its discretion, the Board may establish a trust fund or make other arrangements to assure payment of the Supplemental Retirement Benefits
8.	Allocation of Costs.
The cost of Supplemental Retirement Benefits paid to or on behalf of Retired Participants shall be allocated to and be the responsibility of the Company and Participating Corporations.
9.	Administration.
The Committee shall administer the Plan and may appoint an officer of the Company to assist the Committee with this responsibility. The Committee shall have the sole responsibility to interpret the Plan and to adopt such rules and regulations for carrying out the Plan as it may deem necessary. Decisions of the Committee shall be final and binding.
10.	Amendment or Termination.
The Board may at any time amend, modify, or terminate this Plan; provided, however, that any Retired Participants or their surviving spouses receiving Supplemental Retirement Benefits under the Plan at the date of amendment or termination shall continue receiving such benefits as if such amendment or termination had not occurred and provided that any amendment, modification, or termination of the Plan shall not adversely affect the right of any Participant to receive benefits earned prior to such action.
11.	Successor to the Company.
The Company shall require any successor or assign, whether direct or indirect, by purchase, merger, consolidation or otherwise, to all or substantially all of the business and/or assets of the Company, to assume and agree to pay any Supplemental Retirement Benefits in the same manner and to the same extent that the Company would be required to perform if no such succession or assignment had taken place.
12.	Change in Control and Legal Fees.
The Company shall pay all legal fees and expenses that a Retired Participant or a Participant may reasonably incur as a result of the Company's contesting the validity or enforceability of such participant's right to receive benefits under the terms of this Plan following a "Change in Control" of the Company.
In the event that a Change in Control of the Company occurs and a Participant's employment with the Company or its successor(s) terminates, the Participant shall receive a lump-sum payment of his Supplemental Retirement Benefits within 30 days of the Participant's termination. Such benefits shall be calculated as set forth in Section 6.
A Change in Control of the Company shall be deemed to have occurred if (i) any Acquiring Person (as such term is defined in the Rights Agreement dated as of February 13, 1996, between the Company and ChaseMellon Shareholder Services L.L.C.) is or becomes the beneficial owner (as such term is used in Rule 13d-3 under the Securities Exchange Act of 1934) of securities of the Company representing 25 percent or more of the combined voting power of the Company; or (ii) the following individuals cease for any reason to constitute a majority of the number of directors then serving: individuals who, as of May 19, 1998, constitute the Board and any new director (other than a director whose initial assumption of office is in connection with an actual or threatened election contest, including but not limited to a consent solicitation, relating to the election of directors of the Company) whose appointment or election by the Board or nomination for election by the Company's stockholders was approved or recommended by a vote of at least two-thirds (2/3) of the directors then still in office who either were directors on May 19, 1998, or whose appointment, election or nomination for election was previously so approved or recommended; or (iii) the Company's stockholders approve a merger or consolidation of the Company or any direct or indirect subsidiary of the Company with any other corporation, other than a merger or consolidation that would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or any parent thereof) at least 60 percent of the combined voting power of the securities of the Company or such surviving entity or any parent thereof outstanding immediately after such merger or consolidation, or a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) in which no person is or becomes the beneficial owner, directly or indirectly, of securities of the Company representing 25 percent or more of the combined voting power of the Company's then outstanding securities; or (iv) the Company's stockholders approve a plan of complete liquidation or dissolution of the Company or there is consummated an agreement for the sale or disposition by the Company of all or substantially all of the Company's assets, other than a sale or disposition by the Company of all or substantially all of the Company's assets to an entity, at least 60 percent of the combined voting power of the voting securities of which are owned by stockholders of the Company in substantially the same proportions as their ownership of the Company immediately prior to such sale. A Change in Control, however, shall not be considered to have occurred until all conditions precedent to the transaction, including but not limited to, all required regulatory approvals have been obtained.

2.		Purpose of Plan.
The purpose of the Plan is to provide eligible Employees with the opportunity to defer receipt of up to a specified portion of their annual Compensation in order to reduce current taxable income and to provide for future retirement needs.
3.		Administration.
The Management Performance Committee of the Company's Board of Directors shall construe and administer the Plan and shall have full authority to make such rules and regulations deemed necessary or desirable to carry out such administration. The Management Performance Committee may appoint an officer or department to assist with the administration of the Plan. All interpretations of the Plan by the Committee shall be final and binding on all parties, including Participants, Beneficiaries and Employers.
4.		Eligibility.
All officers and any key manager designated by his Employer are eligible to participate in the Plan.
5.		Election to Defer Compensation.
In order to participate in the Plan during 1993, an Employee must make an election to defer at least $500 per month of participation. For the first Plan Year, which is a partial Plan Year, such election must be made at or prior to the effective date of this Plan and can only be made as to Compensation to be paid for future services. In order to participate in subsequent Plan Years, an Employee must make an election to defer an annual amount from $5,000 to 50 percent of annual Compensation. Such elections must be made prior to the first day of the Plan Year in which it is to become effective and can only be made with respect to Compensation to be paid for future services. A deferral election, once made, shall remain in effect for subsequent Plan Years until it is revoked or modified by the Participant. A Participant can modify or revoke his deferral election with respect to Compensation to be paid for future services by submitting a new election or a revocation prior to the beginning of the Plan Year in which such new deferral election or revocation is to become effective. All notices of election or revocation shall be made on forms prepared by the Company's Secretary and shall be dated, signed, and filed with the Company's Secretary.
6.		Elections, Deemed Investments.
When making an election to defer Compensation, an Employee must choose between two methods of determining earnings on the deferred Compensation. He may choose to have such earnings calculated as if the deferred Compensation had been invested in shares of the Company's Common Stock (the "Common Stock Option") or he may choose to have earnings calculated by adding 100 basis points to the interest
payable on a 10-Year Treasury Note (the "Treasury Note Option"). An Employee may also choose to allocate his deferred Compensation between the options in increments of 25 percent, 50 percent, or 75 percent.
The Participant must designate his deemed investment for all of the Compensation he elects to defer in any given year. He may change the deemed investment for future deferred Compensation by filing the appropriate notice with the Company's Corporate Secretary before the first day of each calendar year, but such change shall not affect the method of determining the value of any Compensation deferred in a prior year.
Any deferred Compensation accounted for under the Common Stock Option shall be accounted for as if invested in shares of Common Stock purchased at a price equal to the closing benchmark price of the Common Stock on the New York Stock Exchange each payroll date. This amount shall be credited to a Participant's account on a payroll date basis. In addition, a Participant's account shall be credited on a quarterly basis with an amount equal to the dividends that would have become payable during the deferral period if actual purchases of Common Stock had been made, with such dividends accounted for as if invested in Common Stock as of the payable date for such dividends. Any credited shares treated as if they were purchased with dividends shall be deemed to have been purchased at a price equal to the closing benchmark price of the Common Stock on the dividend payment date.
If a Participant elects the Treasury Note Option, his account will be credited with any Compensation deferred by the Participant in any given month. Interest shall be calculated at a monthly rate calculated by dividing by 12 the sum of 100 basis points plus the rate for the appropriate 10-Year Treasury Note as quoted in the Wall Street Journal under "Consumer Savings Rates" on the Thursday closest to the end of the month or other published source of such rates as identified by Questar Corporation's Treasury department. The appropriate 10-Year Treasury Note shall be the Note that is the closest (in terms of months) to the date on which the interest is credited. The interest deemed to be credited to each Account shall be based on the amount credited to such Account at the beginning of each particular month.
7.	Integration with Other Plans.
If an employee elects to reduce his Compensation under the terms of this Plan, six percent of any Compensation deferred shall be accounted for under the terms of the Questar Corporation Deferred Share Plan. A Participant's benefits (if any) under the Company's Executive Incentive Retirement Plan shall be based on the Participant's base salary including any base salary deferred under the terms of this Plan, the Company's Deferred Share Plan, the Deferred Share Make-up Plan, and any base salary reductions under the Company's Tax-Qualified Plan or Cafeteria Plan and pre-tax parking arrangements. A Participant's benefits (if any) under the Company's Supplemental Executive Retirement Plan shall be based on the Participant's Compensation plus any Compensation deferred under the terms of this Plan and the Company's Deferred Share and Deferred Share Make-Up Plans.
8.	Account Statement.
Within 60 days after the end of the calendar year, a statement shall be sent to each Participant listing the balance in his account as of the end of the year.
9.	Payment of Account Balances.
When making the first deferral election under Paragraph 5, a Participant shall determine when to receive the Compensation deferred by him. A Participant can elect to receive such deferred Compensation at a specified date prior to his termination of employment, e.g., December 31, 2002, upon his termination of employment or at a specified time within five years after his termination of employment. A Participant can also elect whether to receive deferred Compensation in a lump-sum payment or in a number of annual installments (not to exceed four). A Participant cannot change such elections for Compensation previously deferred, but can change such elections for Compensation deferred in future years.
Under the Common Stock Option, the account balance shall be valued using the Fair Market Value of the Company's Common Stock on the last day of the calendar month preceding payment and shall be converted to a cash balance based upon such Fair Market Value. Under an installment payout, the Participant's first installment shall be equal to a fraction of the balance credited to his account (or the portion of his account to be paid in installments) as of the last day of the calendar month preceding such payment, the numerator of which is one and the denominator of which is the total number of installments selected. The amount of each subsequent payment shall be a fraction of the balance in the Participant's account as of the last day of the calendar month preceding each subsequent payment, the numerator of which is one and the denominator of which is the total number of installments elected minus the number of installments previously paid.
Under the Treasury Note Option, the account balance shall be valued as of the date of withdrawal, which is the last day of the calendar month preceding payment, with interest credited to such date. Under an installment payout, the Participant's first installment shall be equal to a fraction of the balance credited to his account (or the portion of his account to be paid in installments) as of the last day of the calendar month preceding such payment, the numerator of which is one and the denominator of which is the total number of installments selected. The amount of each subsequent payment shall be a fraction of the balance in the Participant's account as of the last day of the calendar month preceding each subsequent payment, the numerator of which is one and the denominator of which is the total number of installments elected minus the number of installments previously paid.
10.	Miscellaneous Payment Issues.
(a)    Adverse Tax Determination. If there is a determination by the Internal Revenue Service (IRS) that a Participant should be taxed on some or all of the amounts allocated to his account prior to the distribution date(s) elected under Paragraph 9, the Participant may elect to have all amounts determined to be currently taxable paid to him immediately prior to the time he must pay any taxes owed as a result of such IRS determination.
(b)     Change in Control. Notwithstanding any other provision of this Plan, in the event of a "Change in Control" of the Company (as defined below), all deferred Compensation credited to a Participant's account shall be distributed to him within 60 days following the Change in Control.
A Change in Control of the Company shall be deemed to have occurred if (i) any "Acquiring Person" (as such term is defined in the Rights Agreement dated as of February 13, 1996, between the Company and U. S. Bank, National Association ("Rights Agreement")) is or becomes the beneficial owner (as such term is used in Rule 13d-3 under the Securities Exchange Act of 1934) of securities of the Company representing 25 percent or more of the combined voting power of the Company; or (ii) the following individuals cease for any reason to constitute a majority of the number of directors then serving: individuals who, as of May 19, 1998, constitute the Company's Board of Directors ("Board") and any new director (other than a director whose initial assumption of office is in connection with an actual or threatened election contest, including but not limited to a consent solicitation, relating to the election of directors of the Company) whose appointment or election by the Board or nomination for election by the Company's stockholders was approved or recommended by a vote of at least two-thirds of the directors then still in office who either were directors on May 19, 1998, or whose appointment, election or nomination for election was previously so approved or recommended; or (iii) the Company's stockholders approve a merger or consolidation of the Company or any direct or indirect subsidiary of the Company with any other corporation, other than a merger or consolidation that would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or any parent thereof) at least 60 percent of the combined voting power of the securities of the Company or such surviving entity or its parent outstanding immediately after such merger or consolidation, or a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) in which no person is or becomes the beneficial owner, directly or indirectly, of securities of the Company representing 25 percent or more of the combined voting power of the
Company's then outstanding securities; or (iv) the Company's stockholders approve a plan of complete liquidation or dissolution of the Company or there is consummated an agreement for the sale or disposition by the Company of all or substantially all of the Company's assets, other than a sale or disposition by the Company of all or substantially all of the Company's assets to an entity, at least 60 percent of the combined voting power of the voting securities of which are owned by stockholders of the Company in substantially the same proportions as their ownership of the Company immediately prior to such sale. A Change in Control, however, shall not be considered to have occurred until all conditions precedent to the transaction, including but not limited to, all required regulatory approvals have been obtained.
(c)     Method of Payment. All amounts credited to a Participant's account shall be distributed to him or, in the event of his death, to his Beneficiary, in cash and in accordance with the election made by the Participant.
(d)     Source of Payments. Each participating Employer will pay all benefits for its Employees arising under this Plan, and all costs, charges and expenses relating to such benefits, out of its general assets.
11.	Amendment and Termination of Plan.
The Plan may be amended, modified or terminated by the Company's Board of Directors at any time. Provided, however, no such amendment, modification or termination shall be made in the event there is a Change in Control, as defined in Paragraph 10(b). In addition, no amendment, modification, or termination shall reduce any deferred benefit under the Plan reflected in a Participant's account prior to the date of such amendment or termination.
12.	Non-assignability of Benefits.
To the extent consistent with applicable law, the Participant's deferred benefits under this Plan shall not be assigned, transferred, pledged, or encumbered or be subject in any manner to alienation or attachment.
13.	No Creation of Rights.
Nothing in this Plan shall confer upon any Participant the right to continue as an Employee of an Employer. The right of a Participant to receive a cash distribution shall be an unsecured claim against the general assets of his Employer. Nothing contained in this Plan nor any action taken hereunder shall create, or be construed to create, a trust of any kind, or a fiduciary relationship between the Company and the Participants, Beneficiaries, or any other persons. All accounts under the Plan shall be maintained for bookkeeping purposes only and shall not represent a claim against specific assets of any Employer.
14.	Effective Date.
The Plan, as originally adopted, was effective November 1, 1993. The Plan, as amended and restated, is effective January 1, 2003, and shall remain in effect until it is discontinued by action of the Company's Board of Directors.

In addition, any Employee whose annual Compensation exceeds the Compensation Limit and who participates in the Investment Plan also participates in the Plan.
5.	Election to Defer Compensation and Deemed Investment.
(a)    Deferral Election. In order to participate in the Plan, an Employee must make an election to defer from 2 to 6 percent of his annual Compensation in excess of the Compensation Limit. For the first Plan Year, which is a partial Plan Year (1989), such election must be made at or prior to the effective date of this Plan and can only be made as to Compensation to be paid for future services. For all subsequent Plan Years, the election must be made prior to the first day of the Plan Year in which it is to become effective and can only be made with respect to Compensation to be paid for future services. A deferral election, once made, shall remain in effect for subsequent Plan Years until it is revoked or modified by the Participant. A Participant can modify or revoke his deferral election with respect to Compensation to be paid for future services by submitting a new election or a revocation prior to the beginning of the Plan Year in which such new deferral election or revocation is to become effective. All notices of election or revocation shall be made on forms prepared by the Company's Secretary and shall be dated, signed, and filed with the Company's Secretary.
(b)    Special Situation. Any election to participate in the Deferred Share Make-up Plan shall be deemed to constitute an election to participate in this Plan as of January 1, 2002 for any Participant who will make his maximum Elective Deferral eligible for a Matching Allocation to the Investment Plan before he hits the Compensation Limit. Such Participant will be deemed to elect to have his compensation earned after he makes the maximum Elective Deferral reduced by 6 percent and accounted for under the terms of this Plan until his compensation actually hits the Compensation Limit. Any compensation deferred pursuant to this election shall be handled under the terms of the Plan and be accounted for with Deferred Shares.
(c)    Deemed Investment. Any amounts deferred by a Participant shall be accounted for as if invested in shares of Common Stock purchased at a price equal to the closing benchmark price of the Common Stock on the New York Stock Exchange each payroll date. This amount shall be credited to a Participant's account each payroll period as of January 1, 2002. In addition, a Participant's account shall be credited on a quarterly basis with an amount equal to the dividends that would have become payable during the deferral period if actual purchases of Common Stock had been made, with such dividends accounted for as if invested in Common Stock as of the payable date for such dividends. Any credited shares treated as if they were purchased with dividends shall be deemed to have been purchased at a price equal to the closing benchmark price of the Common Stock on the dividend payment date. Each share of Common Stock that is deemed to be purchased under this Paragraph 5(c) shall be reflected in a Participant's account as a Deferred Share.
6.	Matching Allocations.
(a)    Amount. A Participant who makes an election under Section 5 is entitled to the same Matching Allocations as are made under the terms of the Investment Plan. The Matching Allocations are 100 percent for the first 3 percent of contributed Compensation and 60 percent for the second 3 percent.
When there were Excess ESOP Allocations under the Investment Plan for a Plan Year prior to 2000, a Participant was entitled to an additional allocation under this Plan if he is employed by an Employer on the last day of such Plan Year or if his employment terminated during such Plan Year as a result death, retirement, or Disability. Such additional allocation, or "Excess ESOP Allocation," was calculated by multiplying the compensation deferred by the Participant under the Plan during the Plan Year by the same percentage used for the Excess ESOP Allocation in the Investment Plan for the comparable year. Any Compensation deferred pursuant to this Plan between January 1, 1998 and the effective date of the Deferred Share Make-Up Plan that is represented by Deferred Shares transferred to such plan shall be excluded from the Compensation deferred pursuant to the terms of this Plan for purposes of calculating the Excess ESOP Allocation.
The amount of Matching Allocations shall be accounted for as if invested in shares of Common Stock purchased at a price equal to the closing benchmark price paid for shares of Common Stock reported on the New York Stock Exchange on the applicable payroll date. Effective January 1, 2002, Common Stock deemed to have been purchased with Matching Allocations shall be credited to a Participant's account on each payroll date
In addition, a Participant's account shall be credited on a quarterly basis with an amount equal to the dividends that would have become payable during the deferral period if actual purchases of Common Stock had been made, with such dividends accounted for as if invested in Common Stock as of the payable date for such dividends. Any credited shares treated as if they were purchased with dividends shall be deemed to have been purchased at a price equal to the closing benchmark price of the Common Stock on the dividend payment date. Each share of Common Stock that is deemed to be purchased under this Section.6 shall be reflected in the Participant's account as a Deferred Share.
(b)    Vesting. A Participant shall be vested in the portion of his account attributable to Matching Allocations to the same extent as such Participant is vested in any Matching Allocations credited to his account under the Investment Plan.
7.	Transfer of Existing Account Balances, Deferred Share Make-Up Plan.
Any Deferred Shares allocated to a Participant's account balance under this Plan prior to June 1, 1998, were transferred to the Deferred Share Make-Up Plan as of such date to the extent that such Deferred Shares were attributable to 6 percent of Compensation deferred in excess of the Compensation Limit and could be segregated from any Deferred Shares attributable to 6 percent of any Compensation deferred pursuant to the Company's Deferred Compensation Plan.
8.	Statement of Deferred Share Account.
An annual statement shall be sent to each Participant within 60 days following the end of each year showing for each preceding Plan Year the Compensation deferred, Matching Allocations, Excess ESOP Allocations (if any), the total Deferred Shares credited to the Participant's account, and the number of these Deferred Shares that are attributable to the Participant's deferred Compensation, Matching Allocations, Excess ESOP Allocations (if any), and reinvested dividends. Such information shall be shown on a payroll date basis.
9.	Payment of Account Balance.
(a)    Period of Deferral. When making the first deferral election under Paragraph (a) of Section 5, a Participant shall elect to receive all deferred Compensation, Matching Allocations, and Excess ESOP Allocations (if any) either in a lump-sum payment within 45 days following his death, Disability, or termination of employment or in a number of annual installments (not to exceed four), the first of which would be payable within 45 days following his death, Disability or termination of employment with each subsequent payment payable one year thereafter. The account balance shall be valued using the Fair Market Value of the Company's Common Stock on the last day of the calendar month preceding payment and shall be converted to a cash balance based upon such Fair Market Value. Under an installment payout, the Participant's first installment shall be equal to a fraction of the balance credited to his account as of the last day of the calendar month preceding such payment, the numerator of which is one and the denominator of which is the total number of installments selected. The amount of each subsequent payment shall be a fraction of the balance in the Participant's account as of the last day of the calendar month preceding each subsequent payment, the numerator of which is one and the denominator of which is the total number of installments elected minus the number of installments previously paid.
(b)    Adverse Tax Determination. If there is a determination by the Internal Revenue Service (IRS) that a Participant should be taxed on some or all of the amounts allocated to his account prior to the distribution date(s) elected under Paragraph (a) of this Section 9, the Participant may elect to have all amounts determined to be currently taxable paid to him immediately prior to the time he must pay any taxes owed as a result of such IRS determination.
(c)    Change in Control. Notwithstanding any other provision of this Plan, in the event of a "Change in Control" of the Company, all Deferred Shares credited to a Participant's account shall be converted to cash equal in amount to the Fair Market Value of the Deferred Shares if converted into shares of the Company's Common Stock. The cash shall be distributed to him within 60 days following the Change in Control. The account balance shall be valued using the Fair Market Value of the Company's Common Stock on the last day of the calendar month preceding payment.
A Change in Control of the Company shall be deemed to have occurred if (i) any "Acquiring Person" (as such term is defined in the Rights Agreement dated as of February 13, 1996, between the Company and U. S. Bank National Association ("Rights Agreement")) is or becomes the beneficial owner (as such term is used in Rule 13d-3 under the Securities Exchange Act of 1934) of securities of the Company representing 25 percent or more of the combined voting power of the Company; or (ii) the following individuals cease for any reason to constitute a majority of the number of directors then serving: individuals who, as of May 19, 1998, constitute the Company's Board of Directors ("Board") and any new director (other than a director whose initial assumption of office is in connection with an actual or threatened election contest, including but not limited to a consent solicitation, relating to the election of directors of the Company) whose appointment or election by the Board or nomination for election by the Company's stockholders was approved or recommended by a vote of at least two-thirds of the directors then still in office who either were directors on May 19, 1998, or whose appointment, election or nomination for election was previously so approved or recommended; or (iii) the Company's stockholders approve a merger or consolidation of the Company or any direct or indirect subsidiary of the Company with any other corporation, other than a merger or consolidation that would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or any parent thereof) at least 60 percent of the combined voting power of the securities of the Company or such surviving entity or its parent outstanding immediately after such merger or consolidation, or a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) in which no person is or becomes the beneficial owner, directly or indirectly, of securities of the Company representing 25 percent or more of the combined voting power of the Company's then outstanding securities; or (iv) the Company's stockholders approve a plan of complete liquidation or dissolution of the Company or there is consummated an agreement for the sale or disposition by the Company of all or substantially all of the Company's assets, other than a sale or disposition by the Company of all or substantially all of the Company's assets to an entity, at least 60 percent of the combined voting power of the voting securities of which are owned by stockholders of the Company in substantially the same proportions as their ownership of the Company immediately prior to such sale. A Change in Control, however, shall not be considered to have occurred until all conditions precedent to the transaction, including but not limited to, all required regulatory approvals have been obtained.
(d)    Method of Payment. All amounts credited to a Participant's account shall be distributed to him or, in the event of his death, to his Beneficiary, in cash and in accordance with the election made by the Participant.
(e)    Source of Payments. Each participating Employer will pay all benefits for its Employees arising under this Plan out of its general assets.
10.	Amendment and Termination of Plan.
The Plan may be amended, modified or terminated by the Company's Board of Directors at any time; provided, however, no such amendment, modification or termination shall be made in the event there is a Change in Control, as defined in Paragraph (c) of Section 9. In addition, no amendment, modification, or termination shall reduce any deferred benefit under the Plan reflected in a Participant's account prior to the date of such amendment or termination.
11.	Non-assignability of Benefits.
To the extent consistent with applicable law, the Participant's deferred benefits under this Plan shall not be assigned, transferred, pledged, or encumbered or be subject in any manner to alienation or attachment.
12.	No Creation of Rights.
Nothing in this Plan shall confer upon any Participant the right to continue as an Employee or to receive annual Compensation in excess of the Compensation Limit. The right of a Participant to receive a cash distribution shall be an unsecured claim against the general assets of his Employer. Nothing contained in this Plan nor any action taken hereunder shall create, or be construed to create, a trust of any kind, or a fiduciary relationship between the Company and the Participants, Beneficiaries, or any other persons. All accounts under the Plan shall be maintained for bookkeeping purposes only and shall not represent a claim against specific assets of any Employer.
13.	Effective Date.
The Plan, as originally adopted, was effective on July 1, 1989. The Plan, as most recently amended and restated, is effective January 1, 2003, and shall remain in effect until it is discontinued by action of the Company's Board of Directors.

3.	Administration.
The Management Performance Committee of the Company's Board of Directors shall construe and administer the Plan and shall have full authority to make such rules and regulations deemed necessary or desirable to carry out such administration. The Management Performance Committee may appoint an officer or department to assist with the administration of the Plan. All interpretations of the Plan by the Committee shall be final and binding on all parties, including Participants, Beneficiaries and Employers.
4.	Eligibility.
All officers and key managers whose annual Compensation is expected to exceed the Compensation Limit and who participate in the Investment Plan are eligible to participate in the Plan.
5.	Transfer of Account Balances, Deferred Share Plan.
Any Deferred Shares allocated to an Employee's account balance under the Deferred Share Plan prior to June 1, 1998, were transferred to this Plan as of such date to the extent that such Deferred Shares are attributable to six percent of Compensation deferred in excess of the Compensation Limit and could be segregated from any Deferred Shares attributable to six percent of any Compensation deferred pursuant to the Company's Deferred Compensation Plan.
6.	Election to Defer Compensation and Deemed Investment.
(a)    Deferral Election. Any Employee who has previously made an election to defer Compensation for purposes of the Deferred Share Plan shall automatically become a Participant in this Plan for 1998 and subsequent years at such time that his/her Compensation exceeds the Compensation Limit. A deferral election, once made, shall remain in effect for subsequent Plan Years until it is revoked or modified by the Participant. A Participant can modify or revoke a deferral election with respect to Compensation to be paid for future services by submitting a new election or a revocation prior to the beginning of the Plan Year in which such new deferral election or revocation is to become effective. All notices of election or revocation shall be made on forms prepared by the Company's Secretary and shall be dated, signed, and filed with the Company's Secretary.
(b)    Deemed Investment. Any amounts deferred by a Participant shall be accounted for as if invested in shares of Common Stock purchased at a price equal to the closing benchmark price of the Common Stock on the New York Stock Exchange each payroll date. This amount shall be credited to a Participant's account each payroll date as of January 1, 2002. In addition, a Participant's account shall be credited on a quarterly basis with an amount equal to the dividends that would have become payable during the deferral period if actual purchases of Common Stock had been made, with such dividends accounted for as if invested in Common Stock as of the payable date for such dividends. Any credited shares treated as if they were purchased with dividends shall be deemed to have been purchased at a price equal to the closing benchmark price of the Common Stock on the dividend payment date. Each share of Common Stock that is deemed to be purchased under this Paragraph 6(b) shall be reflected in a Participant's account as a Deferred Share.
7.	Matching Allocations.
(a)    Amount. A Participant who makes an election under Section 6 is entitled to the same Matching Allocations as are made under the terms of the Investment Plan. The Matching Allocations are 100 percent for the first 3 percent of contributed Compensation and 60 percent for the second 3 percent.
When there were Excess ESOP Allocations under the Investment Plan for a Plan Year prior to 2000, a Participant was entitled to an additional allocation under this Plan if he is employed by an Employer on the last day of such Plan Year or if his employment terminated during such Plan Year as a result of death, Disability or retirement. Such additional allocation shall be calculated by multiplying the Compensation deferred by the Participant under the Plan during the Plan Year by the same percentage used for the Excess ESOP Allocation in the Investment Plan for the comparable year. Any Compensation deferred pursuant to the Deferred Share Plan between January 1, 1998 and the effective date of this Plan that is represented by Deferred Shares transferred to this Plan shall be included in Compensation deferred pursuant to the terms of this Plan for purposes of calculating the Excess ESOP Allocation.
The amount of Matching Allocations shall be accounted for as if invested in shares of Common Stock purchased at a price equal to the closing benchmark price paid for shares of Common Stock reported on the New York Stock Exchange on the applicable payroll date. Effective January 1, 2002, Common Stock deemed to have been purchased with Matching Allocations shall be credited to a Participant's account each payroll date.
In addition, a Participant's account shall be credited on a quarterly basis with an amount equal to the dividends that would have become payable during the deferral period if actual purchases of Common Stock had been made, with such dividends accounted for as if invested in Common Stock as of the payable date for such dividends. Any credited shares treated as if they were purchased with dividends shall be deemed to have been purchased at a price equal to the closing benchmark price of the Common Stock on the dividend payment date. Each share of Common Stock that is deemed to be purchased under this Section 7 shall be reflected in the Participant's account as a Deferred Share.
(b)    Vesting. A Participant shall be vested in the portion of his account attributable to Matching Allocations to the same extent as such Participant is vested in any Matching Allocations credited to his account under the Investment Plan.
8.	Statement of Deferred Share Account.
An annual statement shall be sent to each Participant within 60 days following the end of each year showing for each preceding Plan Year the Compensation deferred, Matching Allocations, Excess ESOP Allocations (if any), the total Deferred Shares credited to the Participant's account, and the number of these Deferred Shares that are attributable to the Participant's deferred Compensation, to Matching Allocations, Excess ESOP Allocations (if any), and to reinvested dividends. Such information shall be shown on a payroll date basis.
9.	Payment of Account Balance.
(a)    Period of Deferral. The Participant's prior deferral election(s) for the Deferred Share Plan shall be applicable to this Plan for any amounts transferred to this Plan. When making a first deferral election under Paragraph (a) of Section 6, a Participant shall elect to receive all deferred Compensation, Matching Allocations, and Excess ESOP Allocations either in a lump-sum payment within 45 days following his death, Disability, or termination of employment or in a number of annual installments (not to exceed four), the first of which would be payable within 45 days following his death, Disability or termination of employment with each subsequent payment payable one year thereafter. The account balance shall be valued using the Fair Market Value of the Company's Common Stock on the last day of the calendar month preceding payment and shall be converted to a cash balance based upon such Fair Market Value. Under an installment payout, the Participant's first installment shall be equal to a fraction of the balance credited to his account as of the last day of the calendar month preceding such payment, the numerator of which is one and the denominator of which is the total number of installments selected. The amount of each subsequent payment shall be a fraction of the balance in the Participant's account as of the last day of the calendar month preceding each subsequent payment, the numerator of which is one and the denominator of which is the total number of installments elected minus the number of installments previously paid.
(b)    Adverse Tax Determination. If there is a determination by the Internal Revenue Service (IRS) that a Participant should be taxed on some or all of the amounts allocated to his account prior to the distribution date(s) elected under Paragraph (a) of this Section 9, the Participant may elect to have all amounts determined to be currently taxable paid to him immediately prior to the time he must pay any taxes owed as a result of such IRS determination.
(c)    Change in Control. Notwithstanding any other provision of this Plan, in the event of a "Change in Control" of the Company, all Deferred Shares credited to a Participant's account shall be converted to cash equal in amount to the Fair Market Value of the Deferred Shares if converted into shares of the Company's Common Stock. The cash shall be distributed to him within 60 days following the Change in Control. The account balance shall be valued using the Fair Market Value of the Company's Common Stock on the last day of the calendar month preceding payment.
A "Change in Control" of the Company shall be deemed to have occurred if (i) any "Acquiring Person" (as such term is defined in the Rights Agreement dated as of February 13, 1996, between the Company and U. S. Bank National Association) is or becomes the beneficial owner (as such term is used in Rule 13d-3 under the Securities Exchange Act of 1934) of securities of the Company representing 20 percent or more of the combined voting power of the Company; or (ii) the following individuals cease for any reason to constitute a majority of the number of directors then serving: individuals who, as of May 19, 1998, constitute the Company's Board of Directors (Board) and any new director (other than a director whose initial assumption of office is in connection with an actual or threatened election contest, including but not limited to a consent solicitation, relating to the election of directors of the Company) whose appointment or election by the Board or nomination for election by the Company's stockholders was approved or recommended by a vote of at least two-thirds (2/3) of the directors then still in office who either were directors on May 19, 1998, or whose appointment, election or nomination for election was previously so approved or recommended; or (iii) the Company's stockholders approve a merger or consolidation of the Company or any direct or indirect subsidiary of the Company with any other corporation, other than a merger or consolidation that would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to represent (either by remaining outstanding or by being converted
into voting securities of the surviving entity or any parent thereof) at least 60 percent of the combined voting power of the securities of the Company or such surviving entity or any parent thereof outstanding immediately after such merger or consolidation, or a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) in which no person is or becomes the beneficial owner, directly or indirectly, of securities of the Company representing 25 percent or more of the combined voting power of the Company's then outstanding securities; or (iv) the Company's stockholders approve a plan of complete liquidation or dissolution of the Company or there is consummated an agreement for the sale or disposition by the Company of all or substantially all of the Company's assets, other than a sale or disposition by the Company of all or substantially all of the Company's assets to an entity, at least 60 percent of the combined voting power of the voting securities of which are owned by stockholders of the Company in substantially the same proportions as their ownership of the Company immediately prior to such sale. A Change in Control, however, shall not be considered to have occurred until all conditions precedent to the transaction, including but not limited to, all required regulatory approvals have been obtained.
(d)    Method of Payment. All amounts credited to a Participant's account shall be distributed to him or, in the event of his death, to his Beneficiary, in cash and in accordance with the election made by the Participant.
(e)    Source of Payments. Each participating Employer will pay all benefits for its Employees arising under this Plan.
10.	Amendment and Termination of Plan.
The Plan may be amended, modified or terminated by the Company's Board of Directors at any time; provided, however, no such amendment, modification or termination shall be made in the event there is a Change in Control, as defined in Paragraph (c) of Section 9. In addition, no amendment, modification, or termination shall reduce any deferred benefit under the Plan reflected in a Participant's account prior to the date of such amendment or termination.
11.	Non-assignability of Benefits.
To the extent consistent with applicable law, the Participant's deferred benefits under this Plan shall not be assigned, transferred, pledged, or encumbered or be subject in any manner to alienation or attachment.
12.	No Creation of Rights.
Nothing in this Plan shall confer upon any Participant the right to continue as an Employee or to receive annual Compensation in excess of the Compensation Limit. The right of a Participant to receive a cash distribution shall be an unsecured claim against the general assets of his Employer. Nothing contained in this Plan nor any action taken hereunder shall create, or be construed to create, a trust of any kind, or a fiduciary relationship between the Company and the Participants, Beneficiaries, or any other persons. All accounts under the Plan shall be maintained for bookkeeping purposes only and shall not represent a claim against specific assets of any Employer.
13.	Effective Date.
The Plan as originally adopted, was effective on May 19, 1998. The Plan, as most recently amended and restated, is effective January 1, 2003, and shall remain in effect until it is discontinued by action of the Company's Board of Directors.
