PXP to Acquire Large Resource Base with 359 MMBOE of Total Estimated Reserves in the Prolific Piceance Basin in Colorado for $946 Million

Plains Exploration & Production Company

HOUSTON /PRNewswire-FirstCall/ -- Plains Exploration & Production Company (NYSE: PXP) ("PXP" or the "Company") today announced that it has entered into a definitive agreement to acquire from a private company all of its interests in oil and gas producing properties, covering over 60,000 gross acres/55,000 net acres, over 200 producing/productive wells and over 3,000 additional potential drilling locations in the Mesaverde geologic section of the prolific Piceance Basin in Colorado, plus the associated midstream assets including a 25 percent interest in the Collbran Valley Gathering System. PXP will pay $900 million in cash and issue one million shares of PXP common stock. The transaction is valued at approximately $946 million, based on PXP's closing price on April 17, 2007. The effective date of the transaction is January 1, 2007.

The properties currently produce approximately 6,000 barrels of oil equivalent per day of which nearly 97 percent is natural gas. PXP estimates proved reserves are approximately 64 million barrels of oil equivalent (MMBOE) with an additional 295 MMBOE of unproven resource potential, totaling 359 MMBOE of total estimated reserves (proved, probable and possible reserves).

"The Piceance Basin is one of the most prolific basins in the United States. This transaction provides PXP a meaningful acreage position with substantial reserve and production growth opportunities. We have identified over 3,000 drilling locations each with an estimated ultimate recovery of nearly 1.0 billion cubic feet equivalent per well. With 5 drilling rigs operating, we expect to initially drill about 100 wells per year. We are confident 2007 will be another highly successful year for PXP and its shareholders. This accretive acquisition is an immediate contribution to accelerating PXP's per share growth," said James C. Flores, PXP's Chairman, President and Chief Executive Officer."

Following the acquisition PXP's operations will be concentrated in California, Colorado and the Gulf Coast region. The transaction is expected to close during the second quarter subject to customary closing conditions. PXP intends to fund the acquisition with borrowings under its bank credit facility. Lehman Brothers Inc. acted as the financial advisor and rendered a fairness opinion to PXP.
