3 Maari Field Location & Ownership The Maari & Manaia Fields are located in Mining Permit PMP38160 in the offshore Taranaki Basin, New Zealand, approximately 35km south of the giant Maui gas field and 70km south-west of Cape Egmont. The Mining Permit is operated by OMV New Zealand on behalf of the Maari Joint Venture consisting of: OMV New Zealand Limited: 69% Todd Maari Limited: 16% Horizon Oil International Limited: 10% Cue Taranaki Pty Ltd 5% Slide 2 OMV New Zealand Ltd, The Maari Growth Projects Carey Mills, 31 March 2015

4 Current JV formed Exploration & Development History Oil accumulations at Manaia and Maari were first identified in 1970 and 1983 respectively. The combination of location, prevailing oil price, resource size and the physical oil properties deemed development uneconomic. The current JV was formed in 2002 and took final investment decision on the Maari Development in 2005 Phase 1 development drilling commenced in December 2008 and continued through to November 2009 with first oil in February Maari has produced over 25 million barrels of oil Maari Growth drilling project commenced in April 2014 Slide 3 OMV New Zealand Ltd, The Maari Growth Projects Carey Mills, 31 March 2015

5 Producing Reservoirs Maari produces oil from four separate reservoir sequences: Maari M2A Sandstone One horizontal producer with 1.2km of horizontal section Maari Moki Sandstone Five horizontal producer wells with a total of ~11km of horizontal section (drilling of a sixth producer well is currently ongoing). One horizontal water injector (additional horizontal producer / injector to be drilled) Maari Mangahewa Formation One horizontal oil producer Manaia Mangahewa Formation One ERD horizontal oil producer with 1.5km of horizontal section Slide 4 OMV New Zealand Ltd, The Maari Growth Projects Carey Mills, 31 March 2015

6 Installed Facilities The installed Maari facilities consist of a Well Head Platform & FPSO linked by subsea umbilicals & flow lines.
