Grubb, former President and Chief Operating Officer of SandRidge Energy, Inc., as a consultant both in connection with our upcoming proxy contest to replace the entire board of directors of SandRidge and to explore strategic alternatives for SandRidge on our behalf.</div>

<div><br>
</div>

<div style="FONT-SIZE: 10pt; FONT-FAMILY: 'Times New Roman', Times, serif; TEXT-ALIGN: justify; TEXT-INDENT: 36pt">Matt has almost 30 years of experience in the oil and gas industry and is currently President and Chief Executive Officer of Compass Production Partners, LP, a private oil and gas company with operations in Northern Louisiana and the Midland Basin of West Texas. Prior to joining Compass Production Partners in January 2014, Matt was President and Chief Operating Officer of SandRidge, where he was employed from 2006 to 2013 (well before the company's 2016 bankruptcy filing). Matt was employed by Samson Resources from 1995 to 2006 and last served as Division Operations Manager of East Texas and Southeast U.S. Regions for Samson Resources. Matt currently serves as a board member on the Foundation Board of the Children's Center Rehabilitation Hospital, a non-profit organization. Matt earned a Bachelor of Science degree in Petroleum Engineering in 1986 and a Master of Science degree in Mechanical Engineering in 1988, both from Texas A&amp;M University.</div>
