Management Comments

Mr. Gary C. Evans, Chairman of the Board and Chief Executive Officer of Magnum Hunter, commented, “One of our primary goals as we rebuild our Company has been to attract high quality and experienced personnel. In order for us to efficiently drill and develop our vast Appalachian leasehold acreage position during this low commodity price environment in a manner that expands EUR’s and at the same time reduces finding costs, we must have this type of talent in-house. We believe Keith Yankowsky brings all the knowledge and experience we have been seeking. As a native of the area, a graduate of the college located in the same town as our primary operating office, and having managed and overseen the drilling and completion of over 1,100 wells in this region, we are confident that necessary improvements to our operational performance will occur in the future.”
