Diverse Portfolio of Properties As of December 31, 2007, NRPLP had 2.1 billion tons of proven and probable reserves. Our reserves are subject to 191 leases with 66 lessees. Our reserves are geographically diverse and cover a broad range of heat and sulfur content. By offering both metallurgical and steam coal, our coal reserves are marketable to a diverse customer base, thereby enabling our lessees to adjust to changing markets and sustain sales volumes and prices. By having reserves in different geographic areas with various types of coal reserves, our lessees are able to serve a broad number of markets and take advantage of changing customer preferences.
