Furthermore, Mr. Hantke’s extensive experience in executive management positions in the independent refining industry, considered by many to be a similar industry to the Independent Power Production (IPP) sector, and as a director of public and nonpublic boards enables him to provide the Board significant managerial, strategic, and financial oversight. As a result, his fellow directors have elected him as Chair of the Company’s Audit Committee and determined that he is an “audit committee financial expert” as defined by SEC rules.
