Quicksilver Resources Announces $200 Million Expansion of Senior Credit Facility

Quicksilver Resources Inc. (NYSE: KWK) announced that effective November 30th, the company has received increased commitments under its senior credit facility to enable it to borrow up to $600 million under the facility, representing an additional $200 million in liquidity. The additional commitment in the five-year revolving credit facility was absorbed by the existing group of 14 major U.S. and international banks led by J.P. Morgan Securities, Inc., BNP Paribas and Bank of America Securities, LLC. The facility commitments, which expire in July 2009, are allocated among U.S. and Canadian funds. The amendment to the Combined Credit Agreement also increased the amount of other indebtedness that Quicksilver is permitted to have outstanding by $170 million, subject to the satisfaction of certain conditions (including the terms thereof being satisfactory to the lenders under the Combined Credit Agreements).

Phil Cook, senior vice president and chief financial officer commented, "The expansion of this facility enhances our capital structure and allows the company to continue to pursue its development programs into 2006, which should provide significant value and growth for our stockholders. This increase in the borrowing base is a demonstration of the quality of our long-lived reserves, the banks' continued confidence in our management team, and our strong growth prospects."
