“All Questar business units posted record net income in the first nine months of 2008,” said Keith O. Rattie, Questar Chairman, President and CEO. “Questar E&P grew natural gas and oil-equivalent production 20% in the period, driven by a 32% increase in Midcontinent production.”

Third Quarter 2008 Highlights

Questar E&P grew natural gas, oil and natural gas liquids (NGL) production 34% to 45.3

billion cubic feet of natural gas equivalent (Bcfe) compared to 33.9 Bcfe for the 2007 period. Natural gas comprised 89% of reported production volumes.

Average realized natural gas prices at Questar E&P increased $1.17 per thousand cubic feet (Mcf), or 18%, and average realized crude oil and NGL prices increased $32.39 per barrel (bbl), or 59%. Natural gas hedges increased reported revenues by $24.5 million, while oil hedges decreased revenues by $13.9 million.

Net mark-to-market losses on natural gas basis-only hedges decreased net income $14.0 million in the 2008 quarter compared to a gain of $5.6 million in the year-earlier period.

Sales of non-core assets at Questar E&P increased net income $36.5 million in the 2008 quarter compared to a loss of $0.2 million in the year-earlier period.

Wexpro grew its investment base 32% to $374.9 million at September 30, 2008. Wexpro produced 12.2 Bcf of cost-of-service gas for delivery to affiliate Questar Gas compared to 7.3 Bcf in the 2007 quarter.

Gas Management net income grew 84%, driven by higher gathering and processing margins. Net processing revenues increased 69% to $26.5 million due to a 71% increase in fee-based processing volumes and higher keep-whole processing margins.

Energy Trading net income increased 40% to $5.9 million as a result of increased marketing margins caused by wider regional natural gas basis differentials and increased overall commodity-price volatility compared to the 2007 period. The marketing margin totaled $9.2 million compared to $6.5 million in the year-ago period.

Questar Pipeline grew net income to $15.4 million, a 28% increase over the prior-year period. The increase was driven by higher transportation revenues from expansion projects completed in the fourth-quarter of 2007 and increased NGL revenues.

Questar Gas seasonal loss was $8.8 million, slightly greater than a year ago. A higher gross margin was offset by higher operating, maintenance and interest expenses in the quarter.

Questar earned an 18.1% return on assets (ROA – defined as earnings before interest and income taxes divided by average total assets) for the trailing 12-month period ended September 30, 2008. Market Resources ROA was 22.1%; Questar Pipeline ROA was 10.2%; and Questar Gas ROA was 7.7%.

Questar Raises 2008 EPS Estimate and Provides Initial 2009 Guidance

Questar now expects full-year 2008 net income to range from $3.70 to $3.80 per diluted share compared to previous guidance of $3.50 to $3.60 per diluted share. The company’s revised guidance now assumes that the NYMEX/Rockies basis differential will range from $2.00 to $3.00per MMBtu for the remainder of 2008, compared to $3.50 to $4.50 per MMBtu assumed in previous guidance. The guidance assumes the NYMEX natural gas price will range from $6.00 to $7.00 per MMBtu for currently unhedged 2008 production for the rest of the year, and the prompt-month NYMEX crude oil price will range from $70.00 to $80.00 per bbl for unhedged volumes.

Questar also provided initial 2009 net income and production estimates. The company estimates that 2009 net income could range from $3.05 to $3.25 per diluted share. This guidance assumes that the average 2009 NYMEX natural gas price will range between $6.50 to $7.50 per MMBtu for currently unhedged production and that the average 2009 prompt-month NYMEX crude oil price will range between $70.00 to $80.00 per bbl for unhedged volumes. The company also estimates Questar E&P 2009 production will range from 185 to 193 Bcfe, representing growth of approximately 10 to 15% from projected 2008 production volumes. Questar anticipates a capital investment program of $1.5 to $1.6 billion. The company believes it has sufficient liquidity to support its operating and capital investment plans through 2009. The company currently has $475 million of undrawn debt capacity on subsidiary Market Resources $800 million revolving credit facility. In addition, the company has $365 million of committed commercial paper credit lines with eight commercial banks.

The company’s guidance assumes hedges in place on the date of this release and excludes mark-to-market gains and losses on basis-only swaps and one-time items such as gains and losses on sale of

assets. These and other assumptions are summarized in the table below:

NYMEX/Midcontinent basis differential per MMBtu^(a)	$3.00-$2.00	$3.00-$2.00	$2.00-$1.00

^(a)For unhedged volumes for the remainder of 2008 and 2009

Questar E&P has hedged about 82% of forecast natural gas and oil-equivalent production for the remainder of 2008 with fixed-price swaps. Additionally, the company has hedged about 2% of forecast remainder of 2008 production with natural gas basis-only swaps (see table at the end of this release).

The company estimates that a $1.00 per MMBtu change in the average NYMEX price of natural gas for the remainder of 2008 would result in about a $0.01 change in earnings per diluted share.

The company also estimates that a $10.00 per barrel change in the average NYMEX price of oil for the remainder of 2008 would result in about a $0.01 change in earnings per diluted share.

Questar E&P Net Income Increases 92% in Third Quarter, 63% for First Nine Months of 2008

Questar E&P – a Market Resources subsidiary that acquires, explores for, develops and produces natural gas and oil – reported production of 45.3 Bcfe in the third quarter of 2008 compared to 33.9 Bcfe in the 2007 period, a 34% increase. Higher realized natural gas, crude oil and NGL prices and growing production in the quarter more than offset a 12% increase in average production costs. Increased production costs were driven by higher production tax and interest expense. Net mark-to-market losses on natural gas basis-only swaps decreased net income $14.0 million in the 2008 quarter compared to a $5.6 million gain in the 2007 quarter. Sales of non-core assets increased net income $36.5 million in the 2008

quarter compared to a $0.2 million loss in the 2007 quarter. For the first nine months of 2008, Questar E&P net income rose 63% to$360.1millioncompared to $220.3 million a year earlier, driven by a 20% increase in production, higher realized prices and gains on asset sales.

Questar may enter into derivative transactions on up to 100% of forecast production from proved reserves to lock in acceptable returns on invested capital and to protect cash flow and net income from a decline in commodity prices. The company uses natural gas basis-only swaps to protect cash flows and net income from widening natural gas-price basis differentials that may result from capacity constraints on regional gas pipelines.

Questar E&P production costs (the sum of depreciation, depletion and amortization expense, lease operating expense, general and administrative expense, allocated interest expense, and production taxes) per unit of gas-equivalent production increased 12% compared to the 2007 third quarter due primarily to increased production taxes and higher allocated interest expense.

	September 30,			September 30,
	(per Mcfe)			(per Mcfe)
	2008	2007	Change	2008	2007	Change

Production costs	$3.79	$3.38	12%	$3.94	$3.34	18%

Production volume-weighted average depreciation, depletion and amortization per Mcfe (the DD&A rate) increased due to higher costs for drilling, completion and related services, increased cost of steel casing, other tubulars and wellhead equipment. The DD&A rate also increased due to the ongoing depletion of older, lower-cost reserves and the increasing component of Questar E&P production derived from recently acquired, higher-cost fields in the Midcontinent.

Lease operating expense per Mcfe increased due to higher costs of materials and consumables, increased produced-water disposal costs and increased well-workover activity.

General and administrative expense per Mcfe decreased as the result of increased production and lower expenses primarily due to reduced legal costs.

Allocated interest expense per unit of production increased primarily due to financing costs related to the first quarter 2008 acquisition of natural gas development properties in northwest Louisiana.

Production taxes per Mcfe were higher due to higher natural gas and oil sales prices in the 2008 period. Production taxes are based on a percentage of sales prices, before the impact of hedges.

Wexpro Net Income Up 38% in Third Quarter, 28% for First Nine Months of 2008

Wexpro – a Market Resources subsidiary that develops and produces cost-of-service reserves for affiliate Questar Gas – reported net income of $20.4 million compared to $14.8 million in the prior-year period, a 38% increase. Wexpro results benefited from a higher average investment base compared to the prior-year period. Wexpro investment base at September 30, 2008, was $374.9 million compared to $284.6 million a year ago, a 32% increase. For the first nine months of 2008, Wexpro net income was $55.4 million compared to $43.4 million for the prior-year period, a 28% increase, primarily due to a higher investment base.

Under a long-standing agreement with the states of Utah and Wyoming, Wexpro recovers its costs and earns an unlevered after-tax return of about 19 to 20% on its investment base – the investment in commercial wells and related facilities, adjusted for working capital and reduced for deferred income taxes and accumulated depreciation.

Gas Management Net Income Up 84% in Third Quarter, 59% for the First Nine Months of 2008

Questar Gas Management (Gas Management) – Market Resources’ gas-gathering and processing-services business – reported net income of $24.5 million compared to $13.3 million in the prior-year period, an 84% increase, driven by higher gathering and processing margins. Net processing revenues increased 69% to $26.5 million due to increased processing volumes and a higher frac spread. Gas Management grew fee-based gas-processing volumes 71% in the third quarter to 57.5 million MMBtu. Fee-based gas-processing revenues grew 66% compared to the year-ago quarter, while the frac-spread for keep-whole processing increased 68% or $7.4 million. Approximately 73% of Gas Management net operating revenue (total revenue less processing plant-shrink) was derived from fee-based contracts compared to 74% in the 2007 period. For the first nine months of 2008, Gas Management net income increased 59% to $64.7 million com pared to $40.6 million in the 2007 period, driven by higher gathering and processing margins.

Questar Pipeline Net Income Up 28% in Third Quarter, 33% for First Nine Months of 2008

Questar Pipeline – which provides interstate natural gas transportation and storage services – reported net income of $15.4 million compared to $12.0 million in the prior-year period, a 28% increase, primarily from system expansions placed in service late in 2007 and increased NGL revenues. Revenues increased $11.0 million or 22%, driven by higher transportation and NGL revenues, while operating and maintenance expense increased $2.8 million due to additional operating costs for new transportation facilities. Operating, maintenance, general and administrative expenses totaled $0.09 per decatherm transported, down from $0.14 in the year-earlier quarter, the net result of a 71% increase in transportation volumes and a 13% increase in these expenses.

Questar Pipeline net income rose to $44.0 million in the first nine months of 2008 compared to $33.2 million in the year-ago period, primarily from system expansions placed in service late in 2007. One-time items combined to reduce 2008 net income by $2.1 million. A $6.8 million after-tax loss on the impairment of investment in an underground gas storage project was partially offset by a $2.4 million after-tax gain on the sale of a non-core asset and a $2.3 million after-tax gain on the collection of a note receivable.

Questar Gas Seasonal Net Loss of $8.8 Million in Third Quarter, Net Income Up 2% for First Nine Months of 2008

Questar Gas – which provides retail natural gas distribution services in Utah, Wyoming and Idaho – reported an $8.8 million net loss in the quarter, a $0.3 million increase in its seasonal net loss compared to the year-ago period. The increased loss was driven by higher operating and maintenance expenses, (primarily bad debt costs) and interest expense, partially offset by higher gross margin from new customers. An annualized increase in Utah general rates of $12.0 million went into effect in August 2008.

Questar Gas net income was $19.8 million in the first nine months of 2008, 2% higher than the year-earlier period, primarily as a result of customer growth. Operating, maintenance, general and administrative expenses totaled $103 per customer in the first nine months of 2008 compared to $102 per customer in the 2007 period. At September 30, 2008, Questar Gas served 880,059 customers, up 19,023

or 2.2% from September 30, 2007.
