Quicksilver Gas Services Second-Quarter Net Income Surges 44% in 2010

FORT WORTH, TEXAS (August 9, 2010) – Quicksilver Gas Services LP (NYSE: KGS) today reported net income for the 2010 second quarter of $10.1 million, a 44% increase from the comparable prior year’s net income of $7.0 million.  Earnings before interest, income taxes, depreciation and accretion ("EBITDA"), a non-GAAP measure, increased to $18.8 million in the 2010 quarter, up 20% from the comparable prior-year period.

The company’s total gathered volumes for the 2010 second quarter averaged 325.4 million cubic feet (MMcf) per day, an increase of 33% from the comparable prior-year period.  Continued development of the Alliance and Lake Arlington properties by Quicksilver Resources Inc. (NYSE: KWK) is expected to result in total average gathered volumes for Quicksilver Gas Services in the range of approximately 330 MMcf to 340 MMcf per day for all of 2010.  The company purchased the Alliance midstream assets from Quicksilver Resources in January and has reflected their results in the 2009 financial information by virtue of Quicksilver’s ownership position with us.

“The value of our recent acquisition of the Alliance midstream system was evident during the quarter as gathered volumes increased as anticipated,” said Toby Darden, Quicksilver Gas Services president and chief executive officer.  “More importantly, we efficiently integrated this acquisition into our gathering network which helped to reduce our costs per gathered unit by more than 25% from the first quarter of 2010.  We believe that the opportunity for continued, diversified growth will be further enhanced following completion of the sale of the general partner to Crestwood Midstream Partners later this year.”

For the second quarter of 2010, the company incurred approximately $13.5 million of capital costs, including $1.7 million of maintenance capital.  Expenditures during the quarter included the connection of approximately 2.2 miles of gathering lines and 28 new wells to the gathering system.

At June 30, 2010, the company had approximately $227 million drawn on its $320 million credit facility.

On July 22, the company announced that Quicksilver Resources, the owner of 100% of our general partner, Quicksilver Gas Services GP, had entered into a definitive agreement to sell all of its interests in Quicksilver Gas Services to Crestwood Midstream Partners II, LLC, a portfolio company of First Reserve Corporation.  At closing, which is not subject to financing contingencies and is expected to occur in October 2010, subject to customary closing conditions, Quicksilver Resources will convey all of its ownership of us to Crestwood.  The transaction has no direct impact to our historical financial statements.

Also on July 22, 2010, the company announced that our board of directors declared a cash distribution for the 2010 second quarter of $.42 per common unit, an increase of 7.7% from the previous quarterly rate.  For the three months ended June 30, 2010, distributable cash flow, a non-GAAP financial measure, totaled $15.4 million, a 28% increase from the prior-year quarter, and resulted in a distribution coverage rate of more than 1.2 times for the 2010 second quarter.
