Petrohawk Increases Offering

Petrohawk Energy Corporation announced that it has priced its public offering of 18 million shares of common stock. The Company has granted the underwriters a 30-day option to purchase up to an additional 15%, or 2.7 million shares of common stock, to cover over-allotments, if any. Based on market demand, the Company increased the offering size by three million shares from 15 million shares and increased the underwriters' option by a proportional amount. All shares were offered at $15.00. The offering is expected to settle and close on February 1, 2008, subject to customary closing conditions.

Net proceeds from the offering will be used to pay down a portion of the outstanding borrowings on Petrohawk's senior revolving credit facility, which will provide additional financial flexibility to fund its 2008 capital budget and acquisitions.

Lehman Brothers and Merrill Lynch & Co. are serving as joint book-running managers in the offering.
