(b) If at the expiration of the Primary Term hereof none of the Substances is being produced, but on or before that date reworking operations (including, among other things, cleaning, testing, repair, and replacement of wells and related facilities and equipment necessary to cause production from such wells), or operations for the drilling of a well (including among other things any work or actual operations undertaken or commenced for the purpose of drilling a well on or into the Lands, including without limiting the generality hereof, the preparation of the ground therefore, the building of roads and other facilities therefore, the construction of a derrick and other necessary structures for the drilling of a well followed by the actual operation of drilling in the ground) in search of any of the Substances are commenced on the Lands, the Lease will continue in force for so long as such operations are continuously prosecuted; and, such operations shall be considered to be continuously prosecuted if not more than six (6) months shall elapse between completion or abandonment of one well and beginning of operations for the drilling or reworking of another well. If, as a result of such operations, any of the Substances are produced in commercial quantities or production is restored, the Lease will remain in force for so long as any of the Substances shall be so produced. If said Substances, or any of them are being so produced from any part of the Lands at or after expiration of the Primary Term hereof and all of such production shall thereafter cease, Lessee may, within six (6) months from cessation of such production, resume drilling or reworking operations in an effort to obtain or restore such production of any of the Substances, in which event the Lease shall remain in force for so long as such operations are continuously prosecuted, as provided above; and, if such operations shall result in production in commercial quantities of any of the Substances, for so long as any of them are produced in commercial quantities.
