^** RPS estimates the probability of the Tembo prospect of being oil bearing, if successful at 30%-40%

Mozambique - Onshore Rovuma Exploration - Tembo

• Targeting hydrocarbons trapped in sands of mid Cretaceous and upper Jurassic age.
• The primary target is both structural and stratigraphic in nature and mapped seismic amplitude events show positive AVO characteristics which calibrate well with those seen on seismic in the Offshore Area-1 fields.
• Oil shows were encountered in Cretaceous age sands in both the Mocimboa-1 (onshore) and Ironclad-1 (offshore) wells providing confidence in the local presence of a mature oil and gas source rock. 9

Mozambique - Onshore Rovuma Exploration - Kifaru

• Targeting Miocene, Oligocene, Eocene and Paleocene age sands similar to those tested in adjacent Offshore Area-1 gas fields. May also target Cretaceous.
• The structure is a tilted fault block with multiple mapped closures at different stratigraphic levels. Any trapped gas will likely also spill into an adjacent toe thrust structure (yellow prospect) to the northwest which is a structural look alike to the Windjammer discovery in Offshore Area-1 Block.
• Positive AVO characteristics are evident on the seismic for some of the targeted reservoirs in this prospect. 10

Tanzania - Mnazi Bay Exploration

► Partners1

• Maurel & Prom (operator) 60.075%
• Wentworth 39.925% ¹ TPDC is carried on exploration activities

Summary

	Entering the busiest period in Wentworth's history
Prolific Basin	• Distinctive position in a prolific basin • World-class discoveries have been made in the basin of over 175 Tscf GIIP (29Bboe) • Majority of licenses in the region are held by Majors, Super-Majors and NOCs
Near-Term Activity	• 2 – 4 exploration wells within next 12 months • 2D seismic acquisition ongoing in Mnazi Bay • Appraisal and development wells to add to production for delivery to new pipeline
Significant Upside Potential	• Anadarko was the 'play-opener' in East Africa and is Wentworth's partner and operator of the Onshore Rovuma Block in Mozambique • Discoveries in Mozambique could open up entirely new play fairways • Discoveries in Tanzania can be immediately commercialised through a new pipeline
Production	• Near-term production (Q1 2015) from discovered gas fields in Tanzania underpins the Company's valuation • Cash flow generated commencing 2015 is expected to fund future exploration and development activity
