Corporate Presentation Technology, Exploration, Discovery: The Dynamic Face of TAG April 2010

Disclaimer

Undiscovered Resources and BOE Undiscovered Hydrocarbon-In-Place (â&#x20AC;&#x153;OOIPâ&#x20AC;?, equivalent to undiscovered resources) is that quantity of petroleum that is estimated, on a given date, to be contained in accumulations yet to be discovered. There is no certainty that any portion of the undiscovered resources will be discovered or that, if discovered, it will be economically viable or technically feasible to produce. The term "barrels of oil equivalent" or "boe" may be misleading, particularly if used in isolation. A boe conversion ratio of six thousand cubic feet (6 mcf) to one barrel (1 bbl) is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.

East Coast Basin Exploration

Stratigraphy & Strategy: TAG’s 3-Pronged Approach § Shallow (Waitangi Hill): Shallow oil (200m-300m) historic oil discovery revisited § Conventional: Miocene prospects (<1500m) 2-10 mm bbl / prospect potential reserve size § Unconventional: Widespread oil-shale opportunities (< 2000m) analogous to the Bakken and Barnett

East Coast Basin: PEP 38348

Phase 1: Waitangi Hill § 530,535 acres, 100%-TAG owned § 1912 Bore hole still bubbling 50 degree API, sweet crude oil and gas today § Oil geochemically typed as Waipawa/ Whangai source § Historic well reported oil to surface from 200m @ 20-50 bbls/d § First of three Cored Strat wells now complete – shallow oil and gas at high pressure discovered § Further results to define shallow development potential and underlying source potential

East Coast Basin: PEP 38349

Phase 1: Boar Hill § 1,695,266 acres, 100%-TAG owned § Potential for stacked conventional and unconventional targets § 4-way dip closure on Miocene through Paleocene Formations § Waipawa-Whangai fractured shale system widespread & thickly developed across area § Significant amount of oil and gas seeps § Boar Hill -1 exploration well: 1,600m - core and possibly complete shales

East Coast Basin Fractured Shale

Leveraging North American Technology Horizontal drilling with multi-staged frac treatments have unlocked multi-billion barrel plays such as the Bakken and Barnett in North America

The Benefits of Technology: A 2500â&#x20AC;&#x2122; well with staged fractures, contacts over 400 times the amount of reservoir than a conventional vertical well through the same formation.
