"Shareholder Fir Tree plans to vote against the company's pending purchase of Pogo Producing (PPP). In a letter to Plains Exploration, Fir Tree said the deal is no longer attractive, because of recent turmoil in the credit markets and because Plains Exploration is so undervalued. Fir Tree said that Plains Exploration, an energy company, could generate more than $1 billion in aftertax proceeds from the "opportunistic" sale of its noncore assets. Without doing the deal, the company could also buy back 20 million to 25 million of its shares, Fir Tree said. If Plains Exploration successfully forms an upstream master limited partnership, its shares could be worth $70 to $75, Fir Tree said in the letter. Fir Tree reported ownership of 6,651,600 shares (9.1% of the total outstanding)"
