"These are robust natural gas price hedges compared to monthly index prices over the past several years," stated James T. Huffman, President. "Natural gas prices are the single most important driver of our financial performance, and these hedges secure excellent prices for the first three quarters of fiscal 2007. In the face of record high gas storage levels, these hedges also reduce the effect of price uncertainty at a time when we are making significant capital outlays to further increase our production."

Hedges include contracts indexed to the NYMEX and to Panhandle Eastern Pipeline Company for Texas, Oklahoma mainline. For comparative purposes, hedges indexed to Panhandle Eastern Pipeline Company are expressed on a NYMEX basis. For hedges indexed to Panhandle Eastern Pipeline Company, the individual month price (basis) differentials between the NYMEX and Panhandle Eastern Pipeline Company range from minus $1.46 in the winter months to minus $0.90 in the spring months.
