New Lease offer North Tip Fayette

Hi, I’m trying to help parents/cousins get a better deal as they had in past with Clayton and Weber. Land is off 152 and Wormley lane. Most of their land is Bastrop.I own in both counties.

Offer (upped it already from initial) 1/5 royalty $25/ac seismic bonus $125/ac Lease bonus $50/ac pre-paid surface usage fee X company will have 1 year to come back and execute the lease 3 years with a 2 year renewal option

Thoughts on this? I’ve read about cleanup? here and asking to get that paid for by them. Not sure if that’s correct terminology. Any help appreciated! Thanks, Chris
