How does the following excerpt affect an existing lease or does it have no bearing over it? I know some have purchase properties in other names to get around this, but how would this affect an existing lease or does it not.   Have 18acres leased HBP with enervest,  32 acres signed with CHK.

 "This Lease also covers and includes, in addition to that above described, all land, if any, contiguous or adjacent to or adjoining the land above described and (a) owned or claimed by Lessor, by limitation, prescription, possession, reversion or unrecorded instrument, or (b) as to which Lessor has a preference right of acquisition."
