HOUSTON, Dec. 1, 2010 /PRNewswire-FirstCall/ -- Plains Exploration & Production Company (NYSE: PXP) ("PXP" or the "Company") provides updates to its derivative positions and its Gulf of Mexico divestments.

DERIVATIVES

PXP has acquired natural gas three-way collars that have a floor price of $4.00 with a limit of $3.00 and a weighted average ceiling price of $4.92 on 200,000 MMBtu per day for 2011. If the index price is below $4.00 per MMBtu, PXP will receive the difference between $4.00 and the index price up to a maximum of $1.00 per MMBtu. If the index price is greater than the ceiling price of $4.92 per MMBtu, PXP will pay the difference between the index price and $4.92 per MMBtu. If the index price is at or above $4.00 per MMBtu but at or below $4.92 per MMBtu, no cash settlement is required.

Additionally, the Company acquired put option spread contracts on 160,000 MMBtu per day for 2012 with a floor price of $4.30 and a limit of $3.00 per MMBtu. If the index price is below $4.30 per MMBtu, PXP will receive the difference between $4.30 and the index price up to a maximum of $1.30 per MMBtu less the option premium. If the index price is at or above $4.30 per MMBtu, PXP only pays the option premium.

PXP has elected not to use hedge accounting for these derivatives and consequently the derivatives will be marked-to-market with fair value gains and losses recognized currently as a gain or loss on mark-to-market derivative contracts on the income statement. A summary of PXP's open commodity derivative positions is included at the end of this release.

GULF OF MEXICO DIVESTMENTS

PXP has informed parties reviewing its deepwater divestment package that PXP will keep the data room open into the first quarter 2011 in order to accommodate existing and several additional participants.  James C. Flores, Chairman, President and CEO of PXP commented, "PXP is extending the process to allow for a complete assessment by all interested parties of PXP's properties.  The divestment is aimed at optimizing the value of PXP's deepwater portfolio and the additional time is an important step in securing the optimum value for PXP shareholders."
