Plains Exploration and Production Information

We are an independent oil and gas company engaged in the activities of acquiring, developing, exploring and producing oil and gas properties primarily in the United States and were formed as a Delaware corporation in 2002. Our oil and gas operations are concentrated onshore California, offshore California, the Gulf Coast Region, the Gulf of Mexico, the Mid-Continent Region and the Rocky Mountains. We also have an interest in an exploration block offshore Vietnam. Assets in our principal focus areas include mature properties with long-lived reserves and significant development opportunities, as well as newer properties with development and exploration potential. We believe our balanced portfolio of assets, our 2009 deleveraging transactions and our ongoing hedging program position us well for both the current commodity price environment and future potential upside as we develop our attractive resource opportunities.
