www.questar.com - Questar Corp. (NYSE:STR) today previewed third-quarter and full-year 2008 financial and operating results and described actions the company is taking in response to the turmoil in financial markets.

Questar will report third-quarter 2008 financial and operating results on October 29. The company expects third-quarter and full-year 2008 net income to be significantly above the current First Call

mean estimates. The company also estimates that Questar E&P 2008 natural gas and oil-equivalent production will come in at the high end of its previous guidance of 166-169 billion cubic feet equivalent.

Subject to ongoing Questar Board review and approval, the company estimates that 2009 capital expenditures may range from $1.5 to $1.6 billion, down from approximately $2.6 billion in 2008. The 2008 capital investment program included approximately $710 million in property acquisitions. The company anticipates that cash flows from operations and existing credit facilities should provide adequate liquidity to fund anticipated 2009 capital investments, operating expenses and dividends. At this level of capital investment, the company estimates that Questar E&P 2009 production may still grow 10-15% from 2008 levels. As previously disclosed, the company has hedged approximately 70% of Questar E&P's forecast 2009 natural gas production at average net-to-the-well prices significantly above the current forward strip (see Questar's latest investor presentation at www.questar.com). The company also reminded investors that operating cash flows from its subsidiaries, Wexpro, Gas Management, Questar Pipeline and Questar Gas, are relatively insensitive to changes in natural gas and crude oil prices.

The company believes it has sufficient liquidity to support its operating and capital investment plans through 2009. The company currently has $475 million undrawn debt capacity on subsidiary Questar Market Resources' $800 million revolving credit facility. In addition, the company has $365 million of committed commercial paper credit lines with eight high-quality banks. Subject to market conditions the company may further bolster liquidity by issuing up to $300 million in term notes under an existing Market Resources shelf registration. The proceeds would be used to pay down the Market Resources revolving credit facility.

"Our intent with this press release is to assure Questar equity and debt investors that we're acting to protect their interests under very difficult market conditions," said Keith Rattie, Questar Chairman, President and CEO.
