Petrohawk Energy Corporation Announces Retirement of William Hahne and Appoints Richard Stoneburner Chief Operating Officer.

HOUSTON -- Petrohawk Energy Corporation (NYSE:HK) ("Petrohawk" or the "Company") today announced the retirement of William (Bill) Hahne and the appointment of Richard (Dick) Stoneburner, currently Executive Vice President - Exploration, to Chief Operating Officer, effective October 1, 2007. Weldon Holcombe, Executive Vice President of Mid-Continent Operations, will continue to manage operations at Elm Grove and Terryville fields and the Fayetteville Shale.

Mr. Hahne joined Petrohawk as Chief Operating Officer following the merger with KCS Energy in July 2006. Since then, the Company has completed a major operational integration and has committed to resource-style development in North Louisiana and Arkansas (Fayetteville Shale). The Company is also in the process of selling its Gulf Coast division and forming a Master Limited Partnership with certain of its long-lived properties in the Permian and Anadarko basins.

"Bill has had an extremely positive influence on Petrohawk," said Floyd C. Wilson, Chairman, President and Chief Executive Officer. "We respect his decision to retire and wish him and his wife, Monica, the best in the future as shareholders and friends of our Company. We are pleased to recognize Dick for his role in our success and for putting in place and managing an outstanding technical team. Dick has been a key decision-maker during all phases of Petrohawk's development, and we support his ongoing leadership."

Mr. Stoneburner, a 30-year veteran of the oil and gas industry, is a founder of Petrohawk. He is credited with leading the Company's 3-D seismic-backed Gulf Coast Division to success, overseeing staff and drilling, and negotiating many joint ventures that supported production and reserve growth in the Division. Additionally, he has overseen exploration efforts in the Company's resource areas, and his most recent area of responsibility has been strategic oversight of Petrohawk's plans in the burgeoning Fayetteville Shale play.

Petrohawk Energy Corporation is an independent energy company engaged in the acquisition, production, exploration and development of oil and gas, with properties concentrated in the Mid-Continent, Gulf Coast and Permian regions.
