Resource Best Estimate for Hawkeye is 112 MMbbl (Net Prospective Resource 74 MMbbl to Otto). Success at Hawkeye will unlock a significant new hydrocarbon play in the deepwater Southern Palawan with material follow-up potential in the carbonate leads and prospects (Gross Prospective Resource Estimate ~11 Tcf and
~400 MMbbl of Condensate) also identified on 3D seismic. With drilling now to occur in Q3 2015, Otto
shareholders will participate in this exciting and material opportunity.

Red Emperor Farm-in

Red Emperor, listed on the ASX and AIM (ASX: RMP, AIM: RMP), has agreed to farm-in to SC55 and earn a
15% working interest by participating in the drilling of the Hawkeye-1 exploration well. Key terms of the farm-in agreement are outlined in Appendix 1.
This farm-in, along with the US$24.5m funding committed by BHP Billiton and the expression of interest received in January 2015 from PNOC-EC for a further 15% working interest, ensures that Otto is fully funded and has mitigated significant financial risk associated with the drilling of Hawkeye-1.

Otto Energy Investments Ltd (a 100% subsidiary of Otto and Operator of SC55) (OEIL) has entered into a Letter of Intent with Maersk Drilling to secure the Maersk Venturer ultra-deepwater drillship to drill the Hawkeye-1 exploration well. Maersk Venturer is one of the most modern and advanced drillships in the world, this rig has the required capability to drill the Hawkeye-1 exploration well.
The Maersk Venturer was commissioned in 2014 and was built at the Samsung Heavy Industries yard in Korea. The Maersk Venturer is one of the newest drillships in the world, capable of operating in up to 3,600 metres of water, with dual drilling derricks, high capacity mud pumps and bed space for 230 personnel. The Maersk Venturer has recently completed work for Total Malaysia. Detailed contractual arrangements with Maersk Drilling will be finalised in the coming weeks.
All required long lead items have now been procured and stored in yards in Labuan, Malaysia. Drilling of

Hawkeye-1 is expected to commence in Q3 2015.

Matthew Allen, Otto's CEO said: "Otto would like to welcome Red Emperor to the SC55 joint venture. Along with our existing joint venture partner, TransAsia Oil and Energy Development Corporation and PNOC-EC, the SC55 joint venture looks forward to delivering the highly important Hawkeye-1 exploration well on behalf of the Philippine Department of Energy.
Securing a drillship of the capability of the Maersk Venturer for the drilling of Hawkeye-1 in Q3 2015 is a major event for Otto. We are now finalising preparations to begin drilling and we look forward to updating our shareholders during 2015 as this activity is undertaken".

Appendix 2:Hawkeye Prospect

SC55 contains a number of distinct exploration play types that provide material opportunities, including: the carbonate gas/condensate trend that has the potential for an oil charge; and turbidite clastic prospects.
The Hawkeye prospect was identified on 2D seismic originally acquired by Otto in 2007 and further defined with the 600 km2 3D seismic acquisition in late 2009. Hawkeye contains:
• 'Best Estimate' STOIIP of ~ 480 MMbbl of oil; and
• 'Best Estimate' Net Prospective Resource of 74 MMbbl of oil.
Hawkeye is planned as a vertical exploration well to test the clastic late Miocene Pagasa formation. Hawkeye is a thrusted, four way closure with direct amplitude support evidenced on high quality 3D seismic acquired

in 2010. Otto plans an exploration well to target the crest of the Hawkeye structure and evaluate results. The well will be plugged and abandoned upon completion of drilling.
Otto has operated in the Philippines for over 10 years and regards the fiscal terms as amongst the best in
Asia. The Philippine fiscal terms assist with protection from low oil price outcomes.
