2.

LEASE TERMS AND RENTALS



(a)

The Lease shall be for a term of ten (10) years from and after the date hereof ("Primary Term") and for so long thereafter as (i) any of the Substances shall be produced in Commercial Quantities from any of the Lands or (ii) for so long as the Lease may be kept in force under any other provision hereof. For the purposes of the Lease, the term "Commercial Quantities" shall mean the production and sale of Substances derived from the Lands to parties dealing at arm's length in amounts sufficient to maintain a profitable level of operations.



(b)

If at the expiration of the Primary Term hereof none of the Substances is being produced in Commercial Quantities, 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 the actual drilling 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 Lessee shall be obligated to continue the rental payments at the rate in effect for the tenth (10th) year of the lease, 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 the actual 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 in Commercial Quantities. If said Substances are being so produced in Commercial Quantities 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.
