On December 5, 2012, FCX and PXP announced that they had entered into a

the proposed merger with FCX must deliver a properly completed election form
to Computershare by 5:00 p.m., New York City time, on May 15, 2013 (the

broker or other nominee may have an election deadline earlier than the
Election Deadline. These stockholders should carefully review any materials
they receive from their bank, broker or other nominee to determine the
election deadline applicable to them.

PXP stockholders who do not make a timely election or fail to deliver a
properly completed election form to Computershare by the Election Deadline
will not be able to elect the form of merger consideration they will receive
in the merger. These non-electing stockholders will receive all cash, all FCX
common stock or a combination of cash and FCX common stock as determined
according to the allocation rules set forth in the merger agreement.
