I just read the following in a Roadway Easement Agreement allowing the pipeline company to construct a road to valves along the pipeline:

4.  Grantor Reservation of Rights.  Grantee does not acquire by this Roadway Easement, but expressly takes subject to [does anyone know what 'takes subject to' means?], and Grantor reserves to Grantor and to Grantor's heirs, successors and assigns, each and all of the following rights in and to Grantor's Land:

(a) All oil, gas, sulphur, uranium, fissional materials and other minerals ("Grantor's Minerals") under the surface of the Roadway Easement to be acquired...

Now they're adding sulphur, uranium and fissional materials?  At least the prior agreement only said "oil, gas and other hydrocarbons."
