Mexico: recent Energy Sector Reform Opening of a high potential energy sector to foreign investors after 78 years of state monopoly. Establishment of a clean and transparent process with an independent regulatory body, CNH. Extensive modern datasets made available for a reasonable cost across most basins. CNH and SENER (Ministry) continuing to mature both the licencing process and terms. Bid conditions comprise government take and defined work programme. Mexico offers large tracts of acreage in proven basins with access via a regular tender process. July 2017 P2
Mexico: Premier Sureste Basin Licence Position Successful entry (10% carried) into Blocks 2 & 7 in Q3 2015 Increased equity to 25% (paying) in May 2017 in Block 7, ahead of Zama well Block 7 Premier 25% Talos (op) 35% Sierra 40% Block 2 July 2017 P3
Mexico: Block 7 Zama Prospect (Premier 25%) W Zama-1 Well E Talos (op.) spudded the well in 166m of water on 21 May using the Ensco 8503 rig. full stack reprocessed seismic data in depth Premier s pre-drill assessment of Zama was of it being a low risk prospect, with a P50 of 300 MM barrels EURR within a range of 100-500 MM barrel Flat Spot ENSCO 8503 Zama-1 Well 3D view of the Zama Prospect showing top structure map and seismic amplitudes of the target interval Good conformance of seismic amplitude with structural contours July 2017 P4
Mexico - Zama-1 W 1 km 2 km Well was side-tracked to west and contingency 16 liner set above fault. ST drilled ahead to 13 5/8 casing point. Zama-1 Well E 80-90 days (mid Aug) to drill and evaluate the well to TD of 4400 mtvd (no well test planned). Forecast cost $61.5m gross, $15.4m net to Premier s 25%. Forward Plan: Case current hole section then drill ahead and evaluate the remainder of Zama Main and Zama Deep secondary target. 3 km 4 km Current hole depth 3381 m MD Flat spot PTD 4426 m MD Zama Main Zama Deep 3D view of Zama showing top structure and seismic amplitudes of the main target seismic section (left) runs E-W through well 5 km 2km Good conformance of seismic amplitude with structure July 2017 P5

Zama Illustrative Development Scenario Illustrative development schematic Mexican fabrication capability Development conceptual engineering will commence shortly. Given the scale of the Zama discovery an illustrative fixed installation development could be much as shown here: Single jacket and significant topsides, with capabilities of producing well in excess of 100,000 bopd Single drill centre with wells drilled from the platform A pipeline to the Dos Bocas terminal The development could leverage the significant Mexican country infrastructure and manufacturing plants. In terms of timetable we would expect to appraise in 2018 and to target first oil well within 5 years. July 2017 P7
