Inherited great grandfather's mineral rights with 18 other people

They gave us the same $200 each to sign the original lease–regret signing that now that I know better; the original lease agreement gave them an option to renew for another five years which they are now trying to exercise so I’m not sure there is anything else I can do about this now. But I do wonder why they need me to sign these new documents and accept their $200 check. If you have any thoughts to share, they would be appreciated. The company is Antero.
