Callon Petroleum Company Announces Increase in Borrowing Base

NATCHEZ, Miss.-- Callon Petroleum Company (NYSE: CPE) announced today that Regions Bank completed a redetermination of the borrowing base under the company's revolving credit facility. As a result, the borrowing base will be increased to $30 million, an increase of 50% over the previously established borrowing base. There are no outstanding draws on the revolving credit facility, and Callon is in compliance with all financial covenants subject to the facility.

Fred Callon, Chairman and CEO, said, "The increase in our borrowing base demonstrates the progress we have made developing our onshore assets in the Permian Basin and Haynesville Shale. By executing our strategic growth plan to reinvest cash flow from our offshore assets into onshore plays offering long-term visible growth, we have been able to increase our estimated net proved reserves to 13.0 million barrels equivalent as of September 1, 2010, a 34% increase since December 31, 2009. Our strategy is working, and we are continuing to build our onshore presence and multi-year inventory of economic drilling locations."
