In an effort to maximize the efficient use of its capital, the Company has established three core operating areas located in the Appalachian, Southwestern and Gulf Coast regions of the United States. The Southwest business unit encompasses operations in East Texas, West Texas, New Mexico and the Midcontinent region of Oklahoma and the Texas Panhandle. This diversity enables the Company to blend the operational risks, production profiles, reserve life indices, natural gas pricing differentials, relative finding and development costs, relative capital requirements and acquisition opportunities. Range believes that this allows for more consistent performance than dependence on one geographical area. The table below summarizes the assets and operations of the Company’s three business units.   Appalachia Southwest Gulf Coast Total Reserve Life Index (years) 20+ 10+ 5+ 15+ Proved Reserves 52% 44% 4% 100% Production  37% 55% 8% 100% Percent Gas  92% 69% 85% 82%

To the extent possible, the Company seeks to operate its properties. It currently
operates properties representing 80% of its reserve value. The Company
believes that operating as a niche player in its three core areas provides
competitive advantages. Range strives to achieve economies of scale in each
of its core areas, while maintaining the regional technical expertise required
to efficiently find and develop reserves. Operating in core areas also facilitates
the identification and exploitation of promising acquisition and development
opportunities.
