SOONER TREND ASSET SUMMARYSTACK Play in Sooner Trend, Oklahoma:

Alta Mesa's assets in the Sooner Trend in Oklahoma are concentrated in and around large, contiguous acreage blocks with multiple productive zones at depths generally between 4,000 feet and 8,000 feet. Activity in these fields is focused on the continued implementation of a multi-year, multi-rig program to develop several pay zones with horizontal drilling and multi-stage hydraulic fracturing of the Mississippian age Osage, Meramec and Manning zones; the Pennsylvanian Oswego; and the definition of similar exploitation opportunities in the Woodford Shale, Hunton Lime, and other formations. The Company has increased its acreage position in the Sooner Trend both within, and contiguous with, its legacy acreage position which is currently over 92,000 net acres. As of June 30, 2016, the Company had four drilling rigs operating in this area with plans to potentially add one additional rig during 2016. In the second quarter of 2016, the Company completed 18 horizontal wells in the Osage formation. Six of the completed wells for the second quarter of 2016 were part of the Company's Joint Development Agreement with BCE-Stack Development LLC (BCE). Alta Mesa had 21 horizontal wells in progress as of the end of the second quarter of 2016, 11 of which were drilled as part of the BCE Joint Development Agreement. Six of the 21 horizontal wells in progress as of June 30, 2016 were on production subsequent to the end of the second quarter. Production during the second quarter of 2016 was approximately 12,300 BOE per day (73% oil and natural gas liquids), up 45% compared to approximately 8,500 BOE per day for the second quarter of 2015.
