On December 20, 2011 (the “Effective Date”), SandRidge Energy, Inc. (the “Company”) entered into employment agreements (the “New Employment Agreements”) with Tom L. Ward, Matthew K. Grubb, James D. Bennett, Todd N. Tipton, and Rodney E.

Under the terms of his New Employment Agreement, Mr. Ward will receive annual grants of restricted stock with a value of at least $16,250,000 throughout the term of the agreement. Upon a termination other than for cause, death, or disability, in connection with certain change in control events, or failure to appoint Mr. Ward as director, Chairman or Chief Executive Officer, Mr. Ward will receive a lump sum payment equal to the value of the restricted stock that he would have received over the next three years if his employment with the Company had continued, payable, in the Company’s discretion, in cash or in shares. In addition, if Mr. Ward is terminated without cause, he will receive his base salary for three years and a cash payment equal to three times his average annual bonus.

Under the terms of their New Employment Agreements, each of Messrs. Grubb, Bennett, Tipton, and Johnson will receive, upon a termination in connection with a change in control event, a lump sum cash payment in amount equal to three times the sum of each of their respective base salary and average annual bonus.
