Trinity East Energy, LLC

Trinity East Energy, LLC, "Trinity" was recently formed by Keystone to concentrate on the drilling and development of the Barnett Shale formation in the eastern frontier of this expanding play. Keystone and its affiliates are the majority owners of Trinity, and Keystone will control all drilling and production activities. Trinity has secured a significant leasehold position and a number of strategic drill sites in this prospective area, and we are actively adding to Trinity's acreage position.
