Item 8.01 Other Events.

        On September 14, 2004, Petrohawk Energy Corporation ("Petrohawk") entered into a hedging arrangement for a portion of Petrohawk's natural gas production for 2005, in the ordinary course of business. This hedge is comprised of costless collars covering a monthly volume of 90,000 MMBTUs for calendar year 2005. Petrohawk had previously entered into a hedging arrangement comprised of costless collars covering a monthly volume of 45,000 MMBTUs for calendar year 2005, and therefore, these hedging arrangements together cover an aggregate monthly volume of 135,000 MMBTUs for calendar year 2005. For a monthly volume of 90,000 MMBTUs, the floor price (NYMEX basis) is $5.50 with a ceiling price (NYMEX basis) of $7.59, and for a monthly volume of 45,000 MMBTUs, the floor price is $5.00 with a ceiling price of $7.83. These hedges together cover less than 50% of Petrohawk's current production.
