Slide 8: The Chuditch-1 Discovery
The Chuditch-1 Discovery ▪ Chuditch-1 drilled by Shell in 1998 ➢ 65m water depth, TD 3035m, well drilled in only 13 days ➢ >25m gas encountered, considerably below mapped crest of structure ➢ Good quality Jurassic Plover Formation reservoirs encountered ➢ Best case discovered resource of ~700 Bcf ➢

Slide 12: Geological Reason for Seabed Anomalies
Geological Reason for Seabed Anomalies Chuditch Area ▪ During the last ice age, around 18,000 years ago, sea levels were up to 120m lower than today ▪ The Bonaparte Shelf was a land area with a large brackish lake occupying the central Bonaparte Depression. 18,000 Years BP 16,000 Years BP ▪ The Chud

Slide 15: SundaGas Go Forward Plan
SundaGas Go Forward Plan PSC Commitment Work Programme ▪ Work programme designed to extract most value from existing seismic, to ensure successful early appraisal and step-out drilling ▪ Likely to drill several wells back-to-back in first drilling campaign 15
Slide 16: Timor Sea Gas Infrastructure and Commercial Context
Timor Sea Gas Infrastructure and Commercial Context ▪ Bayu Undan (BU) supplies gas to Darwin LNG, critical infrastructure for Timor-Leste ▪ TIMOR GAP acquired 56% of Sunrise and plans to develop Tasi Mane LNG ▪ Santos acquired BU and Barossa from ConocoPhillips and reportedly plans to extend BU fiel
