GeoMet Announces Reaffirmation of Borrowing Base at $180 Million

GeoMet, Inc. (NASDAQ:GMET) today announced that the company's bank syndicate, led by Bank of America, reaffirmed the Company's borrowing base of $180 million after completing its mid-year borrowing base determination. The next regular borrowing base determination, which will be based on the December 31, 2008 reserve report as prepared by the Company's independent reserve engineers, is scheduled to be complete on or before June 30, 2009. Commitments under the credit agreement expire in January 2011 and total borrowings are currently $107 million.

Commenting on the reaffirmation of the borrowing base, William C. Rankin, Executive Vice President and CFO, said, "In today's fragile credit markets we believe it is more important than ever to communicate with our investors on the Company's capital availability and liquidity. We have strong relationships with each participant in our five-member bank group and appreciate their continued support. Our 2009 capital and operating budget process is underway and this reaffirmation of our borrowing base ensures we will have the financial resources to execute our growth plan. It is also important to point out the Company's reserves are very long lived and approximately 75% are classified as proved developed, establishing a long-term base for production and cash flow. We replaced our production in 2007 using only 34% of our operating cash flow and expect to do as well in 2008. Accordingly, a reduction in capital expenditures over the short-term, although not anticipated, would not materially impact production or reserve quantities."
