| (1)   | Prior to December 31, 2009 the Company’s Horizon SCO reserves were reported separately in accordance with the SEC’s Industry Guide 7.  With the SEC’s Final Rule in effect January 1, 2010, this synthetic crude oil is now included in the Company’s crude oil and natural gas reserves totals. |
|-----------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| (2)   | Bitumen as defined by the SEC, under the Final Rule, “is petroleum in a solid or semi-solid state in natural deposits with a viscosity greater than 10,000 centipoise measured at original temperature in the deposit and atmospheric pressure, on a gas free basis.”  Under this definition, all the Company’s thermal and primary heavy oil reserves have been classified as bitumen.  Prior to December 31, 2009, these reserves would have been classified within the Company’s conventional crude oil and NGL totals. |
