Oil/Gas Lease Offer, Payne Co, OK

My family members and I have been offered a 3 year lease agreement on 300+ acres of mineral rights in Payne County Oklahoma( 22-18N-2EIM ) at $100 per acre and 3/16th royalty. We have been contacted by two different companies so far. Is this a fair offer or should we negotiate higher? Do you know of any activity in this area?
