We also fear that if the incumbent directors maintain control of SandRidge, the "strategic review process," which we believe is a complete sham, will result in either no deal or, even worse, another Bonanza Creek-style debacle.</div>

In other words, if a stockholder uses the ballot to elect a combination of board nominees recommended by the incumbent board, the board claims that to be a good vote. But, if a stockholder uses the ballot to elect a different combination of board nominees, including combinations that may lead to the election of a controlling slate of our nominees, the incumbent board cries foul.</div>
