Management Comment

Aubrey K. McClendon said of Mr. Davidson's appointment, "We are extremely pleased to have Dick join Chesapeake's Board. Dick has known Chesapeake since our earliest days when he invested in drilling deals that Tom Ward and I generated prior to co-founding Chesapeake in 1989. Over the years, we have stayed in touch with Dick and several years ago began to visit with him in earnest about joining Chesapeake's Board after his retirement from active management at Union Pacific. I believe his experiences as the CEO of a large American public corporation that happens to be one of the country's largest industrial consumers of energy will be of great benefit to Chesapeake, our Board and our shareholders. We are very honored to announce his appointment to Chesapeake's Board."
