On Tuesday, February 18, 2014, the Company announced that it had entered into definitive purchase agreements to acquire 6,450 gross (2,825 net) acres in Martin County for approximately $174 million and that under the terms of the existing joint operating agreement the Company had made offers to the remaining working interest owners to acquire their interests in the acreage for the same proportionate price.
