ATP Approves 3.5MM Share Repurchase Program

ATP Oil & Gas Corp.

ATP's Board of Directors has approved a share repurchase program of up to 3,500,000 shares or roughly 10% of the currently outstanding shares. The program, authorized through the end of 2011, will be funded by free cash flow and the proceeds of asset sales and monetizations.

T. Paul Bulmahn, Chairman and CEO of ATP, stated that "In August 2008, ATP estimated its recoverable oil and gas to be approximately 252 million BOE. With approximately 35 million outstanding shares, each share accounts for roughly seven BOE. This represents a large disconnect between our asset value per share and our trading value per share. With funds generated from our ongoing monetization program and with our internally generated cash flow, we intend to reduce debt, continue our 2008 and 2009 capital development program at levels we deem prudent and actively pursue a share repurchase program. The divestiture of a portion of two selected North Sea properties announced earlier today launches our repurchase of ATP shares. At these prices investing in our own shares is accretive to our equity owners."

All repurchases will be made from time to time in the open market and in privately negotiated transactions when opportunities to do so at favorable prices present themselves in compliance with all applicable laws and regulations, including Securities and Exchange Commission rules.
