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. The results of operations for the three-, nine- and twelve-month periods ended September 30, are not necessarily indicative of the results that may be expected for the year ending December 31, 2001. For further information refer to the consolidated financial statements and footnotes thereto included in the Company's annual report on Form 10-K for the year ended December 31, 2000. Note 2 - Change in Method of Accounting for Gas and Oil Properties On July 1, 2001, Questar elected to change its accounting method for gas and oil properties from the full cost method to the successful efforts method. The change was prompted by the recent acquisition of a company that uses successful efforts. A subsidiary, Wexpro, has always employed the successful efforts method. Management believes that the successful efforts method is preferable and will more accurately present the results of operations of the Company's exploration, development and production activities, minimize asset write-downs caused by temporary declines in gas and oil prices and reflect impairment of the carrying value of the Company's gas and oil properties only when there has been an other-than-temporary decline in their fair value. As a result of this change in accounting, prior year and interim financial statements have been retroactively restated to reflect this change in accounting method. The effect, net of income taxes, was a reduction of retained earnings recorded retroactively as of December 31, 1995, of $37.6 million. This resulted from a reduction of net property, plant and equipment in the amount of $61.9 million and a reduction of deferred income taxes of $24.3 million. The effect of the change in accounting method on previously reported earnings was an increase in net income of $2.0 million or $.03 per diluted share for the six-month period end June 30, 2001 and a decrease in net income of $4.6 million or $.06 per diluted share in the nine-month period ended September 30, 2000. Note 3 - Acquisitions Questar Market Resources, a subsidiary of Questar, acquired 100% of the common stock of Shenandoah Energy, Inc. (SEI) on July 31, 2001 for $403 million in cash including assumed debt. SEI was a privately held Denver-based exploration, production, gathering and drilling company. QMR obtained an estimated 415 billion cubic feet equivalent of proved oil and gas reserves, gas processing capacity of 100 MMcf per day, 90 miles of gathering lines, 114,000 acres of net undeveloped leasehold acreage and four drilling rigs. SEI operations are located primarily in the Uintah Basin of eastern Utah. The transaction was accounted for as a purchase business combination in accordance with accounting principles generally accepted in the United States. The purchase price in excess of the estimated fair value of the assets was assigned to goodwill. The acquisition was financed through bank borrowings. 5 <Page> Assets purchased and liabilities assumed were as follows: <Table> <Caption> (In thousands) Current assets $ 17,332 Property, plant and equipment 401,054 Goodwill 66,823 Other assets 124 Current liabilities (24,328) Other liabilities (8,410) Deferred income taxes (54,364) Other comprehensive loss 4,723 --------- Purchase price, including acquisition costs $ 402,954 ========= </Table> The following unaudited pro forma consolidated results of operations assume the acquisition occurred on January 1, 2000. The pro forma combined financial information reflect Questar's gas and oil operations restated using the successful efforts method of accounting. In addition, the combined financial information were adjusted for the following factors: Adjust depreciation expense to reflect the new basis of SEI's fixed assets. Adjust interest expense to reflect financing costs of the acquisition. Reduce operating expenses to reflect the resignation of several SEI executives. Allocate a portion of corporate overhead costs to SEI Exclude results of operations not purchased by QMR. Calculate income tax expense based on pro forma income before income taxes. <Table> <Caption> Nine Months Ended September 30, 2001 2000 ---------- ---------- (In thousands) Revenues $1,121,076 $ 836,927 Net income 113,023 103,013 Earnings per diluted share $ 1.38 $ 1.28 </Table> Questar Gas completed the purchase of 100% of the stock of Utah Gas Service Company and Wyoming Industrial Gas in exchange for 390,000 shares of Questar common stock on July 12, 2001. With the acquisition, Questar Gas will serve about 10,500 customers in Moab, Monticello and Vernal in Utah and Kemmerer and Diamondville, Wyoming. The acquisition cost $10.9 million, including $6 million of goodwill, and was accounted for as a purchase. Note 4 - Financing QMR borrowed $403 million, including $280 million of bridge loans, to acquire SEI. QMR expects to refinance $200 million of the temporary loans through an offering of long-term notes sometime in the fourth quarter of 2001. During the third quarter of 2001, Questar Gas filed a Form S-3 with the Securities and Exchange Commission to issue up to $100 million of medium-term notes, series D, with maturities of nine months to 30 years. On October 9, 2001, Questar Gas issued $60 million of 11-year notes with a 6.3% coupon rate. On May 11, 2001, Questar Pipeline filed a Form S-3 with the Securities and Exchange Commission to issue up to $250 million of medium-term notes, Series B, with maturities of nine months to 30 years. On May 29, 2001, Questar Pipeline 6 <Page> issued $100 million of 10-year notes with a 7.09% coupon rate. On September 26, Questar Pipeline issued $80 million of 10-year medium-term notes with a coupon rate of 6.57%. Additional proceeds from the sale of notes will likely be used to finance a portion of capital expenditures and partnership investments, estimated at $270 million in 2001. On March 30, 2001, Questar Pipeline redeemed $30 million of its 9 7/8% debentures. The redemption price was equal to 104.67% of the principal amount plus interest from December 1, 2000. In addition, Questar Pipeline redeemed $85 million of its 9 3/8% debentures on June 25, 2001. The redemption price was equal to 104.51% of the principal amount plus twenty-four days of interest. On October 12, 2001, Questar Pipeline borrowed $100 million for a 12-month period. The proceeds were used to repay, through a wholly-owned subsidiary, Questar TransColorado, Inc. (QTC), one-half of the outstanding and currently maturing debt owed by TransColorado Gas Transmission Company (TransColorado). QTC and KN TransColorado, Inc., a subsidiary of Kinder Morgan, each own 50% of TransColorado's debt. On March 6, 2001, QMR, in a public offering, issued $150 million of 7.5% notes due 2011 and applied the proceeds toward repayment of a portion of its outstanding floating-rate bank debt.

SFAS 133 addresses the accounting for derivative instruments, including certain derivative instruments embedded in other contracts. Under the standard, entities are required to carry all derivative instruments in the balance sheet at fair value. The accounting for changes in fair value, which result in gains or losses, of a derivative instrument depends on whether such instrument has been designated and qualifies as part of a hedging relationship and, if so, depends on the reason for holding it. If certain conditions are met, entities may elect to designate a derivative instrument as a hedge of exposure to changes in fair value, cash flows or foreign currencies. If the hedged exposure is a fair-value exposure, the gain or loss on the derivative instrument is recognized in earnings in the period of the change together with the offsetting loss or gain on the hedged item attributable to the risk being hedged. If the hedged exposure is a cash-flow exposure, the effective portion of the gain or loss on the derivative instrument is reported initially as a component of other comprehensive income in the shareholders' equity section of the balance sheet and subsequently reclassified into earnings when the forecasted transaction affects earnings. Any amounts excluded from the assessment of hedge effectiveness, as well as the ineffective portion of the gain or loss, is reported in earnings immediately. As of January 1, 2001, the Company structured a majority of its energy derivative instruments as cash flow hedges. As a result of adopting SFAS 133 in January 2001, the Company recorded a $121 million hedging liability for derivative instruments. Measured at September 30, 2001, the results of hedging activities amounted to a $41.2 million current asset. Settlement of contracts accounted for $68 million of the change, while a decrease in prices of gas and oil on futures markets resulted in a $94.2 million change. The offset to the hedging asset, net of income taxes, was a $19.3 million unrealized gain on hedging activities recorded in other comprehensive income in the shareholder's equity section of the balance sheet. The ineffective portion of hedging transaction recognized in earnings was not significant. The fair-value calculation does not consider changes in fair value of the corresponding scheduled equity physical transactions. The contracts at September 30, 2001 had terms extending through December 2003. About 77% of those contracts, representing approximately $24.6 million, settle and will be reclassified from other comprehensive income in the next 12 months. Effective October 2001, the Company hedged $100 million of variable-rate debt by entering into a fixed-rate interest swap for one year. 8 <Page> Note 7 - Comprehensive Income Comprehensive income is the sum of net income as reported in the Consolidated Statement of Income and other comprehensive income transactions reported in Shareholders' Equity. Other comprehensive income transactions that currently apply result from changes in the market value of securities held for sale, changes in the market value of energy-hedging contracts and changes in holding value resulting from foreign currency translation adjustments. These transactions are not the culmination of the earnings process, but result from periodically adjusting historical balances to market value. Income or loss is realized when the securities available for sale are sold or the gas or oil underlying the hedging contracts is sold. <Table> <Caption> 3 Months Ended 9 Months Ended September 30, September 30, 2001 2000 2001 2000 --------- --------- --------- --------- (In thousands) Comprehensive Income: Net income $ 21,842 $ 26,406 $ 115,605 $ 99,129 Other comprehensive income Unrealized gain on hedging transactions 27,741 30,769 Unrealized gain on securities available for sale (7,736) (17,491) (19,571) (14,915) Foreign currency translation adjustment (1,953) (700) (2,391) (2,176) --------- --------- --------- --------- Other comprehensive income (loss) before income taxes 18,052 (18,191) 8,807 (17,091) Income taxes on other comprehensive income (loss) 6,462 (7,049) 2,811 (7,413) --------- --------- --------- --------- Net other comprehensive income (loss) 11,590 (11,142) 5,996 (9,678) --------- --------- --------- --------- Total comprehensive income $ 33,432 $ 19,357 $ 121,601 $ 91,716 ========= ========= ========= ========= </Table> Note 8 - Reclassifications Certain reclassifications were made to the 2000 financial statements to conform with the 2001 presentation. 9 <Page> Item 2.

Following is a summary of QMR's financial results and operating information. <Table> <Caption> 3 Months Ended 9 Months Ended 12 Months Ended September 30, September 30, September 30, 2001 2000 2001 2000 2001 2000 -------- -------- -------- -------- -------- -------- FINANCIAL RESULTS - (dollars in thousands) Revenues From unaffiliated customers $130,619 $166,163 $513,541 $429,723 $733,018 $545,892 From affiliates 22,720 21,240 75,386 64,642 103,597 87,716 -------- -------- -------- -------- -------- -------- Total revenues $153,339 $187,403 $588,927 $494,365 $836,615 $633,608 ======== ======== ======== ======== ======== ======== Operating income $ 42,465 $ 37,403 $130,308 $ 86,238 $172,230 $106,338 Net income $ 23,051 $ 23,151 $ 82,030 $ 51,670 $108,168 $ 66,158 OPERATING STATISTICS Production volumes Natural gas (in million cubic feet) 18,451 17,361 50,082 51,985 67,060 68,751 Oil and natural gas liquids (in thousands of barrels) Questar E & P, SEI 715 562 1,732 1,679 2,278 2,220 Wexpro 108 126 347 395 473 531 Production revenue Natural gas (per thousand cubic feet) $ 2.94 $ 2.98 $ 3.44 $ 2.55 $ 3.47 $ 2.46 Oil and natural gas liquids (per barrel) Questar E & P, SEI $ 20.24 $ 20.06 $ 20.63 $ 20.48 $ 20.61 $ 19.47 Wexpro $ 24.08 $ 29.06 $ 26.12 $ 26.63 $ 27.15 $ 25.77 Wexpro investment base at September 30, net of deferred income taxes (in millions) $ 153 $ 116 Marketing volumes in energy equivalent decatherms (in thousands of decatherms) 20,758 26,943 68,310 79,148 94,794 104,300 Natural gas gathering volumes (in thousands of decatherms) For unaffiliated customers 21,474 23,205 68,085 68,244 92,810 88,720 For Questar Gas 8,083 7,500 26,989 26,588 37,192 36,381 For other affiliated customers 6,382 6,476 19,782 18,154 26,696 23,730 -------- -------- -------- -------- -------- -------- Total gathering 35,939 37,181 114,856 112,986 156,698 148,831 ======== ======== ======== ======== ======== ======== Gathering revenue (per decatherm) $ 0.13 $ 0.13 $ 0.13 $ 0.13 $ 0.13 $ 0.13 </Table> 10 <Page> REVENUES Revenues were 18% lower in the third quarter of 2001 when compared with the third quarter of 2000 due to a 23% reduction of energy marketing volumes and a 26% decrease in energy marketing prices. Gas production increased 6% over year earlier levels while average selling prices declined 1%. Production of oil and natural gas liquids (NGL) rose 27%, excluding Wexpro. Gas and oil production increases resulted from the acquisition of Shenandoah Energy Inc (SEI) on July 31, 2001. The Company estimates production for the 12 months of 2001 in the range of 83 to 85 billion cubic feet equivalent. In the comparison of the nine month periods, revenues increased 19% in the 2001 period due to higher energy prices for natural gas production and energy marketing transactions. Average realized gas prices were 35% higher. Gas production declined 4% due, in part, to sales of assets in the first quarter and a planned shift in expenditures to cost of service drilling by Wexpro. The Company enters hedging transactions to support the earnings targets and to protect earnings from downward moves in commodity prices. Currently, 62% of projected gas production for the fourth quarter of 2001, including production from SEI properties, is hedged at an average net-to-the-well price of $2.90 per Mcf. For the first half of 2002, about 35% of natural gas production is hedged at a price of $3.51 per Mcf. Approximately, 29% of second half 2002 gas production is hedged at $3.40 per Mcf, net-to-the-well. The Company has hedged 65% of projected fourth quarter 2001 oil production, at an average price of $20.19 per barrel, net-to-the-well. Approximately, 40% of forecast 2002 oil production is hedged at an average price of $24.45 per barrel. The forecast excludes Wexpro production and NGL production. Hedging activities reduced revenues from gas sales by $55.8 million in the first nine months of 2001 and revenues from oil sales by $8.2 million in the first nine months of 2001. EXPENSES Operating and maintenance expenses were higher in the 2001 periods presented when compared with the corresponding 2000 periods. The expenses of operating producing properties increased $5.1 million in the first nine months primarily due to adding properties. Also, the expenses of operating a gas storage facility that began operations in the third quarter of 2000 resulted in a $600,000 increase in the first nine months of 2001. However, legal costs were $4.9 million lower in the first nine months of 2001 following the settlement of a major lawsuit in the second half of 2000. Exploration expenses were unchanged in the nine month comparison. Depreciation, depletion and amortization expense increased slightly in the comparison of the third quarter and first nine months of 2001 with the prior year periods. The average rate for the nine-month period was $.80 per energy equivalent Mcf (Mcfe) in 2001 compared with $.79 in 2000. Other taxes increased because of higher gas prices and the effect on production-related taxes. OTHER INCOME Other income includes a $10.4 million pretax gain from selling nonstrategic gas and oil and gathering properties in the first quarter of 2001. Questar Energy Trading recorded $1.9 million of capitalized interest in the third quarter of 2000 and a $1.6 million pretax gain from selling securities in the second and third quarters of 2000. NET INCOME QMR's net income for the first nine months of 2001 improved 59% over the first nine months of 2000. The increase resulted from higher natural gas prices and increased earnings for Wexpro. Wexpro's net income was $2.5 million higher in 2001. Wexpro increased its investment in development-drilling projects resulting in a $37 million increase in the Wexpro investment base since September 30, 2000. Questar Regulated Services Questar Gas and Questar Pipeline conduct the regulated services of natural gas distribution, transmission and storage. 11 <Page> Natural Gas Distribution Questar Gas conducts natural gas distribution operations.

In the third quarter of 2000, the Company received a $1.3 million refund of gas processing charges that reduced gas costs. The refund represented charges from several previous quarters. The margin was $2.3 million higher in the comparison of the nine-month periods ended September 30, 2001 and 2000 as a result of a 3.9% general rate increase, effective August 11, 2000, increased gas deliveries and new customers. These factors more than offset a 4.6% decline in temperature-adjusted usage per customer in the same nine-month comparison. Total gas volumes delivered were 6% higher in the first nine months of 2001 compared with the same period of 2000. Volumes delivered to residential customers were up 8% due to temperatures that were near normal in the 2001 period compared with 14% warmer than normal in the 2000 period and a 3.6% increase in the number of customers. The third quarter 2001 acquisition of Utah Gas and Wyoming Industrial Gas added about 10,500 customers. The Company expects its customer base at December 31, 2001 will be 25,000 to 28,000 above the previous year. 12 <Page> EXPENSES Operating and maintenance expenses were lower in the 2001 periods when compared with the 2000 periods presented due primarily to lower labor costs resulting from an early retirement program effective October 31, 2000. The reduction of labor costs amounted to about $4 million in the first nine months of 2001 partially offset by a $1.3 million increase in bad debt costs. Bad debt costs have risen in the last 12 months because of the convergence of higher gas prices, increasing number of customers and higher frequency of personal and business bankruptcies. Management is closely monitoring its receivables and is enforcing its credit policies to minimize future uncollectible receivables. Depreciation expense was lower in the 2001 periods when compared with the same periods in 2000 due to computer equipment and software being fully depreciated. Other taxes decreased 13% in the first nine months of 2001 due to an adjustment of prior year taxes in 2000. OTHER INCOME Interest and other income was higher in the 2001 periods when compared with the prior year periods primarily due to interest earned on the undercollected purchased-gas adjustment balance and the investment in gas stored underground. Natural Gas Transmission Questar Pipeline conducts the natural gas transmission, storage and processing operations. Following is a summary of financial results and operating information. <Table> <Caption> 3 Months Ended 9 Months Ended 12 Months Ended September 30, September 30, September 30, 2001 2000 2001 2000 2001 2000 --------- --------- --------- --------- --------- --------- FINANCIAL RESULTS - (dollars in thousands) Revenues From unaffiliated customers $ 12,754 $ 10,454 $ 35,848 $ 30,355 $ 47,993 $ 39,639 From affiliates 17,710 17,733 56,563 57,097 76,042 77,427 --------- --------- --------- --------- --------- --------- Total revenues $ 30,464 $ 28,187 $ 92,411 $ 87,452 $ 124,035 $ 117,066 ========= ========= ========= ========= ========= ========= Operating income $ 14,052 $ 13,739 $ 43,992 $ 43,458 $ 57,387 $ 57,453 Net income (loss) $ 7,193 $ 6,566 $ 21,701 $ 20,766 $ 30,760 $ (6,087) OPERATING STATISTICS Natural gas transportation volumes (in thousands of decatherms) For unaffiliated customers 53,516 44,228 143,522 109,126 193,000 145,987 For Questar Gas 14,303 13,357 78,735 73,718 113,200 103,262 For other affiliated customers 1,981 2,436 3,986 5,437 6,919 8,126 --------- --------- --------- --------- --------- --------- Total transportation 69,800 60,021 226,243 188,281 313,119 257,375 ========= ========= ========= ========= ========= ========= Transportation revenue (per decatherm) $ 0.27 $ 0.28 $ 0.25 $ 0.28 $ 0.24 $ 0.28 </Table> REVENUES Revenues were higher in the 2001 periods compared with the 2000 periods due primarily to increased revenues from transportation operations and gas processing operations. Transportation revenues increased 5% in the third quarter and first nine months of 2001 compared with the 2000 periods primarily from increased demand for firm-transportation service. Firm-transportation volumes reached 64.5 million decatherms (MMDth) in the third quarter of 2001, which was 20% higher than the third quarter of 2000. In the first nine months of 2001, firm-transportation volumes were 212.9 MMDth or 23% higher when compared with the prior-year period as a result of increased regional demand and power 13 <Page> generation. A refund of gas processing fees reduced third quarter 2000 revenues by $1.3 million. Processing fees are determined on a cost-of-service basis and the refund was a result of lower depreciation expense. EXPENSES Operating and maintenance (O & M) expenses were higher in the 2001 periods when compared with the 2000 periods reported primarily because of legal fees, increased transportation activities accompanying the rise in gas volumes, gas processing costs and expenses associated with Questar Southern Trails Pipeline Company. The Company and its subsidiaries have incurred legal costs of $.8 million in the third quarter and $2.1 million in the nine-month period of 2001, primarily associated with defending its position in the TransColorado lawsuit. Fuel gas and other expenses of the gas processing activities increased $.7 million in the first nine months of 2001. Maintenance expenses for the Southern Trails Pipeline were $.4 million higher in the 2001 period. These increases in the first nine months of 2001 were partially offset by $1.8 million of reduced costs resulting from an early retirement program effective October 31, 2000. Depreciation expense was higher in the 2001 periods compared with the 2000 periods as a result of an adjustment recorded in the third quarter 2000. OTHER INCOME Interest and other income for the 2001 periods were higher than the 2000 periods primarily from increased AFUDC (capitalized financing costs) associated with Questar Pipeline's construction projects. Earnings from unconsolidated affiliates includes the Company's share of operating losses from the TransColorado Pipeline partnership of $.5 million in the third quarter and $2.2 million for the first nine months of 2001. Consolidated Results of Operations REVENUES Revenues in the third quarter of 2001 were 8% below the amount reported in the third quarter of 2001 due primarily to a 23% reduction of energy marketing volumes and a 26% decrease in energy marketing prices. In the comparison of the nine-month periods ended September 30, revenues were 32% higher in 2001 as a result of higher prices for gas production and increased prices and volumes associated with gas delivered to distribution customers. EXPENSES The cost of natural gas and other products sold, primarily includes natural gas distribution and energy marketing activities, was lower in the third quarter of 2001due to a decrease in energy costs and volumes. The cost of natural gas and other products sold was higher in the nine-month period ended September 30, 2001, primarily due to increased volumes and costs of deliveries to gas distribution customers. Operating and maintenance expenses were higher in the 2001 periods presented when compared with the same periods in 2000 primarily due to adding gas and oil properties and a storage facility, increasing the number of natural gas customers and acquiring an internet services business. Consonus, an internet services business acquired mid-year 2000, recorded a $1.8 million restructuring charge in 2001. Consonus reported after tax losses of $1.7 million in the third quarter and $5.4 million in the first nine months of 2001 due to lower internet service revenues and higher expenses. Labor cost savings from an early-retirement program offered to qualifying employees partially offset the increases discussed. Depreciation, depletion and amortization expense increased slightly in the 2001 periods presented when compared with the prior year as a result fully depreciating several information systems in 2000 and extending the estimated useful life of a processing plant. Amortization of goodwill was $1.0 million higher in the first nine months of 2001when compared with the same period of 2000. Other taxes increased because of higher gas prices and the effect on production-related taxes. Debt expense was higher in the third quarter of 2001 because of increased borrowings, primarily to fund an acquisition, that more than offset lower rates. 14 <Page> OTHER INCOME In the first quarter of 2001, the Company sold nonstrategic gas and oil and gathering properties and realized a $10.4 million pretax gain. In the first nine months of 2000, the Company recorded a $23.4 million pretax gain from selling securities. The sales of securities resulted in after tax gains of $4.1 million and $14.3 million in the third quarter and first nine months of 2000, respectively. In the third quarter of 2001, the Company wrote down its investment in securities by $1.5 million. There were no securities sales in the first half of 2001. The effective income tax rate for the first nine months was 36.4% in 2001 and 35.2% in 2000. The Company recognized $5.1 million of nonconventional fuel tax credits in the 2001 period and $4.7 million in the 2000 period. Liquidity and Capital Resources Operating Activities Net cash provided from operating activities for the first nine months of 2001 was $53.2 million higher than the amount generated in the same period of 2000. Increased net income, collection of cash deposited as collateral for qualifying hedges and collection of receivables were the primary explanations of the increase. Investing Activities A comparison of capital expenditures for the first nine months of 2001 and 2000 plus an estimate for calendar year 2001 is presented below. Capital expenditures for calendar year 2001 are estimated to be $987 million. <Table> <Caption> Forecast Actual 12 Months 9 Months Ended Ended September 30, Dec. 31, 2001 2000 2001 -------- -------- ------- (In Thousands) Questar Market Resources $547,937 $132,166 620,200 Questar Regulated Services Natural gas distribution 53,332 46,123 76,200 Natural gas transmission 90,827 32,285 278,500 Other 1,783 588 4,800 -------- -------- ------- Total Questar Regulated Services 145,942 78,996 359,500 Corporate and other operations 5,649 10,010 7,300 -------- -------- ------- $699,528 $221,172 $987,000 ======== ======== ======== </Table> Financing Activities In the first nine months of 2001, investing activities exceeded net cash provided from operating activities by $398.2 million as a result of acquiring SEI for $403 million of cash including assumed debt. The Company financed the acquisition through bank borrowings. Financing for the remaining capital expenditures forecasted for 2001 is expected to come from cash provided from operating activities, bank borrowings and issuing long-term debt. Short-term borrowings at September 30, 2001 were comprised of $355.4 million of commercial paper and $110.4 million of short-term bank loans. A year earlier, the Company had issued $152.5 million of commercial paper . In July 2001, QMR borrowed $403 million to finance its acquisition of SEI. QMR expects to refinance $200 million of temporary loans through an offering of long-term notes sometime in the fourth quarter of 2001. On March 6, 2001, Questar Market Resources issued $150 million of medium-term notes and used the proceeds to repay $139 million of long-term bank 15 <Page> loans. On May 11, 2001, Questar Pipeline filed a Form S-3 with the Securities and Exchange Commission to issue up to $250 million of medium-term notes with maturities from nine months to 30 years. Questar Pipeline issued $100 million of medium-term notes on May 29 and $80 million on September 26. Questar Gas issued $60 million of medium-term notes on October 9, 2001. Regulatory Matters On October 23, 2001, the Utah Supreme Court unanimously reversed a Public Service Commission of Utah (PSCU) decision and agreed with Questar Gas' position that certain gas processing costs should have been considered for recovery through usual pass-through proceedings. In December 1999, PSCU denied the Company's request to recover certain costs of processing gas to remove carbon dioxide on procedural grounds. In denying the Company's request, the PSCU provided guidance to seek recovery of future processing fees through other rate making procedures. The Company filed a general rate case that, when settled in August 2000, provided $5 million yearly toward processing costs. The Company appealed to the Utah Supreme Court, maintaining that the gas-balancing account and pass-through proceedings were the proper mechanisms for recovering those processing costs. The Court's decision sends the case back to the PSCU and allows the opportunity for the Company to seek recovery of incurred costs. The Company does not know if its further requests for recovery will be contested on other grounds. On August 30, 2001, the Company filed a pass-on request with the Public Service Commission of Wyoming (PSCW) seeking a $4.6 million reduction of future gas costs collected in rates. The PSCW approved the request. On September 17, 2001, Questar Gas filed a pass-through request with the PSCU that will reduce gas costs in Utah rates by $110.9 millions over the 12 months following an October 1, 2001 effective date. The PSCU gave tentative approval of the request. Business Development On October 5, 2001, QMR announced an agreement with Western Gas Resources, Inc. to form a joint venture that will provide gas gathering and compression services to the Hoback Basin, including Pinedale Anticline and Jonah Field areas in southwest Wyoming. A subsidiary of Questar Gas Management (QGM) and a subsidiary of Western Gas Resources have formed Rendezvous Gas Services, L.L.C. Each entity will contribute certain assets to the joint venture and Rendezvous will construct and operate gas pipeline and compression facilities with the capacity to transport approximately 275 MMcf per day of gas product from Hoback Basin. In addition, the joint venture will deliver gas for blending and processing services to Granger and Blacks Fork processing plants. QGM is a 50% owner and the operator of the Blacks Fork processing plant. Western Gas Resources owns the Granger plant. 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 long-term interest rates. The Company has an investment in a foreign operation that subjects it to exchange-rate risk. QMR also has reserved pipeline capacity for which it is obligated to pay $3 million annually for the next several years, regardless of whether it is able to market the capacity to others. HEDGING POLICY The Company has established policies and procedures for managing market risks through the use of commodity-based derivative arrangements. Primary objectives of these hedging transactions are to support the Company's earnings targets and to protect earnings from downward moves in commodity prices. The Company will target between 50 and 75% of the current year's production to be hedged at or above budget levels by the end of March in the current year. The Company will ladder in these hedges, to reach forward beyond the current year when price levels are attractive. The volume of production hedged and the mix of derivative instruments employed are regularly evaluated and adjusted 16 <Page> by management in response to changing market conditions and reviewed periodically by the Board of Directors. Additionally, under the terms of the Market Resources' revolving credit facility, not more than 75% of Market Resources' production quantities can be committed to hedging arrangements. The Company does not enter into derivative arrangements for speculative purposes. ENERGY-PRICE RISK MANAGEMENT Oil and natural gas prices fluctuate in response to changes in supply and demand. Market Resources bears a majority of the risk associated with commodity price changes and uses hedge arrangements in the normal course of business to limit the risk of adverse price movements. However, these same arrangements usually limit future gains from favorable price movements. QMR held hedge contracts covering the price exposure for about 69.1 million dth of gas and 1.4 million barrels of oil at September 30, 2001. A year earlier the contracts covered 49.8 million dth of natural gas and 1.3 million barrels of oil. The hedging contracts exist for a significant share of QMR-owned gas and oil production and for a portion of energy-marketing transactions. A portion of the contracts at September 30, 2001 had terms extending through December 2003. About 77% of those contracts, representing approximately $24.6 million, settle and will be reclassified from other comprehensive income in the next 12 months. The undiscounted mark-to-market adjustment of financial gas and oil price-hedging contracts at September 30, 2001 was a positive $33.1 million. A 10% decline in gas and oil prices would add $12.6 million to the mark-to-market calculation; while a 10% increase in prices would deduct $12.7 million. The mark-to-market adjustment of gas and oil price-hedging contracts at September 30, 2000 was a negative $80.8 million. A 10% decline in gas and oil prices at that time would decrease the mark-to-market adjustment by $18.9 million to $61.9 million. Conversely, a 10% increase in prices would have resulted in an $18.8 million negative mark-to-market adjustment to a negative $99.6 million balance at that date. The calculations reflect energy prices posted on the NYMEX, various "into the pipe" postings, and fixed prices on the indicated dates. These sensitivity calculations do not consider changes in the fair value of the corresponding scheduled physical transactions (i.e., the correlation between the index price and the price to be realized for the physical delivery of gas or oil production), which should largely offset the change in value of the hedge contracts. INTEREST-RATE RISK MANAGEMENT As of September 30, 2001, the Company owed $172 million of variable-rate long-term debt. The book value of variable-rate debt approximates fair value. Effective October 2001, the Company hedged $100 million of variable-rate debt by entering a fixed-rate interest swap for one year. SECURITIES AVAILABLE FOR SALE Securities available for sale represent equity securities of high-tech and communication enterprises traded on national exchanges. In 2001, the value of these investments has decreased dramatically and is reflected in comprehensive income. In the third quarter of 2001, as a result of market value falling below book basis for two consecutive quarters, the Company wrote down its investment in XO Communications $1.5 million. A 10% change in prices of the entire portfolio would result in a $1.2 million change of value as of September 30, 2001. FOREIGN CURRENCY RISK MANAGEMENT The Company does not hedge the foreign currency exposure of its foreign operation's net assets and long-term debt. Long-term debt held by the foreign operation, amounting to $35.5 million (U.S.), is expected to be repaid from future operations of the foreign company. Recent Accounting Pronouncements In June 2001, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standard (SFAS) 141, "Business Combinations," which addresses financial accounting and reporting for business combinations. 17 <Page> SFAS 141 is effective for all business combinations initiated after June 30, 2001 and for all business combinations accounted for under the pooling method initiated before but completed after June 30, 2001. The Company complied with this new accounting pronouncement in recording two acquisitions closed in the third quarter of 2001. In June 2001, the FASB issued SFAS 142, "Goodwill and Other Intangible Assets," which addresses, among other things, the financial accounting and reporting for goodwill subsequent to an acquisition. The new standard eliminates the requirement to amortize acquired goodwill; instead, such goodwill shall be reviewed at least yearly for impairment. SFAS 142 is effective for fiscal years beginning after December 15, 2001. In 2001, the Company will continue to amortize goodwill acquired prior to July 1, 2001, but will not amortize goodwill acquired subsequent to July 1, 2001. The Company has not yet fully evaluated the impact the remaining provisions of SFAS 142. In June 2001, the FASB issued SFAS 143, "Accounting for Asset Retirement Obligations," which addresses, among other things, 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 that retirement costs be estimated at fair value, capitalized and depreciated over the life of the assets. The new standard may affect the cost basis of gas and oil and rate-regulated assets. SFAS 143 is effective for years beginning after June 15, 2002. The Company has not evaluated the impact of SFAS 143. In August 2001, the FASB issued SFAS 144, "Accounting for the Impairment or Disposal of Long-Lived Assets." The new standard addresses financial accounting and reporting for the impairment or disposal of long-lived assets, specifically, for a segment of a business accounted for as a discontinued operation. SFAS 144 is effective for years beginning after December 15, 2001. The Company has not evaluated the impact of SFAS 144.
