On July 7, 2014, the board of directors (the “Board”) of Synthesis Energy Systems, Inc. (the “Company”) in accordance with the Company’s Certificate of Incorporation and Amended and Restated By-Laws, voted unanimously to appoint Charles M. Brown to fill a vacancy on the Board. Mr. Brown will also serve on the audit committee of the Board.

Mr. Brown, age 55, served as President and Chief Executive Officer of Flow International, Inc., and as a member of its board of directors, from July 2007 through January 2014, when Flow International was merged with and into Waterjet Holdings, Inc. He currently serves as a member of the board of directors of Waterjet Holdings, Inc.

From August 2003 to February 2005, Mr. Brown was the President and Chief Operating Officer of the Pentair Tools Group (which was acquired by Black & Decker Corporation in 2004).

Mr. Brown received a B.A., Economics and Government, from Cornell University, and an M.B.A. from J.L. Kellogg Graduate School of Management at Northwestern University.
