At December 31, 2007 we had the following open derivative positions:

Item 7A. Qualitative and Quantitative Disclosures About Market Risk

Commodity Risk. Our major market risk exposure is the commodity pricing applicable to our oil and natural gas production. Realized commodity prices received for such production are primarily driven by the prevailing worldwide price for oil and spot prices applicable to natural gas. The effects of such pricing volatility have been discussed above, and such volatility is expected to continue. A 10% fluctuation in the price received for oil and natural gas production would have an approximate $12.6 million impact on our 2007 annual revenues.

To mitigate some of this risk, we engage periodically in certain limited hedging activities, including price swaps, costless collars and, occasionally, put options, in order to establish some price floor protection. Costs and any benefits derived fromthese price floors are accordingly recorded as a reduction or increase, as applicable, in oil and gas sales revenue and were notsignificant for any year presented. The costs to purchase put options are amortized over the option period. We do not hold orissue derivative instruments for trading purposes. Net gains (losses) realized by us related to these instruments were $6.4 million, $5.6 million and $(2.3) million or $0.83, $0.98 and $(0.50) per MMBtu for the years ended December 31, 2007, 2006 and 2005, respectively.

Interest Rate Risk. Our exposure to changes in interest rates results from our floating rate debt. The result of a 10% fluctuation in short-term interest rates would have impacted 2007 interest expense by approximately $2.4 million. During 2007, we entered into interest rate swap agreements with respect to amounts outstanding under the amended Second Lien Credit Facility. These arrangements are designed to manage our exposure to interest rate fluctuations through December 31, 2008 by effectively exchanging existing obligations to pay interest based on floating rates for obligations to pay interest basedon fixed LIBOR. These derivatives will be marked-to-market at the end of each period and the realized and unrealized gain or
