FCX can walk away from MMR if vote negative. It was reported that NO vote was needed, but now a vote needed. MMR holders not unanimous on this being a good deal. MMR's holding about to come on line, and many believe GOM sub salt basin asset purchase was a steal for FCX. With vote on the table, FCX not locked into this deal. Many miners like that result. Many MMR holders like that result.
If Plains rejects deal, then debt deal off for Plains and FCX walks away. Bad for Plains. Then FCX just buys MMR and gets the GOM sub salt portfolio. Also. if Plains foolishly rejects, FCX would walk, I think, and the FCX stock would go up 5 points, because the miners would like that: but, if it goes through, the FCX stock will just gradually increase as the revenues are reported each quarter. If PXP deal completed, FCX will double in two years I predict. If rejected, FCX will go up 5 points in a week. JMHO
