Joe, I think the question is have you got a good lease to extend? When the lease expires you could add or delete something from the lease. I am particularly speaking about any charges you agreed to have taken out of your royalty for conditioning gas, as they could be significant to you. Costs add up. In one case I have noticed my brother gets a larger check with a 16% cost-free royalty than I do with a 19% lease royalty with costs. I think you could get something added or deleted in an extension also but you would have less clout than with an expired lease. Good luck.
