CAUTION REGARDING FORWARD-LOOKING STATEMENTS

These slides and the accompanying oral presentation contain certain “forward-looking information” within the meaning of Canadian securities laws, which may include, but is not limited to, statements with respect to future events or future performance, management’s expectations regarding our growth, results of operations, estimated future revenues, requirements for additional capital, production costs and revenue, future demand for and prices of electricity, business prospects, opportunities and estimates of recoverable geothermal energy “resources” or “reserves” or energy generation capacities (at either P 90 Code for Public Reporting). Such forward-looking information reflects or based on the Geothermal management’s current beliefs and is based on information currently available to management.

A number of known and unknown risks, uncertainties and other factors, may cause our actual results or performance to materially differ from any future results or performance expressed or implied by the forward-looking information. Such factors include, among others, those discussed in the section of our prospectus entitled “Risk Factors”. These factors should be considered carefully. The forward-looking information is also based upon what management believes to be reasonable assumptions, including, but not limited to, assumptions about: the success and timely completion of planned exploration and expansion programs, including expansion and improvements to operations in Iceland and to our Soda Lake Operation in Nevada; the growth rate in net electricity consumption; support and demand for non-hydroelectric renewables; government initiatives to support the development of renewable energy generation; the accuracy of resource and reserve estimation methodology and probabilistic analysis used to estimate the quantity of potentially recoverable energy; geological, geophysical, geochemical and other conditions at our properties; the reliability of technical data, including extrapolated temperature gradient, geophysical and geochemical surveys and geothermometer calculations; capital expenditure estimates; availability of capital to fund exploration, development and expansion programs; the differences in financial results reported under IFRS and Canadian GAAP; and general economic conditions. Forward-looking information and statements are also based upon the assumption that none of the identified risk factors that could cause actual results to differ materially from the forward-looking information and statements will occur.

There can be no assurance that the forward-looking information will prove to be accurate, as actual results and future events could differ materially from those anticipated in such information. Accordingly, prospective investors should not place undue reliance on forward-looking information. Other than as required by applicable securities laws, we assume no obligation to update or revise such forward-looking information to reflect new events or circumstances.

GEOTHERMAL – WHAT IS IT?

Geothermal is a proven, global, underexploited, base-load, renewable energy source Literally heat from the earth, derived from deep natural reactions which create magma (molten rock) Requires Heat, Permeability and Water

Surface 1 – 3 km Drill hole depths

Source: University of Utah – the Energy & Geosciences Institute (EGI)

GEOTHERMAL – MAJOR ADVANTAGES

Base Load -

24x7 operation with very high capacity factor +90%

Lowest Levelized (“All-in”) Cost -

commodity prices and risks $60 - $80/MWh. No fuel cost, zero exposure to

Clean -

smallest footprint, minimal to zero emissions

Long-lived

- fully renewable; derived from perpetual earth heat

Low Technological Risk

- plants in operation for over 100 years

TONNES OF CO 2 OFFSETS / 100 MW* OF GENERATION

4 Soda Lake geothermal plant - Nevada *Based on a conversion rate of 0.65 tonnes of CO 2 per MWh of renewable electricity

GLOBAL INSTALLED GEOTHERMAL CAPACITY & EXPLORATION POTENTIAL

A global energy source Established industry, proven technology - world production capacity nearly 10,000 MW First geothermal plant in Italy in 1904 - still producing Biggest current producers: Chevron, Philippines’ PNOC-EDC, Mexico’s CFE, Calpine, Italy’s ENEL, Ormat, Indonesia’s PLN-Pertamina, Iceland’s HS Orka Many of the most promising areas for development are in active global plate boundaries, e.g. “ring of fire” 

USA has large undeveloped resource potential: today 3,000 MW, potential for > 20,000 MW



USA capacity long term > 100,000 MW via EGS (enhanced geothermal system) WORLD GEOTHERMAL PROVINCES “Ring of Fire” US GEOTHERMAL PROVINCES

MAGMA ENERGY - STRATEGY & VALUE CREATION

Geothermal power can be the lowest cost and cleanest form of electricity generation  

Potentially a great cash generator without incentives Incentives (USA, Europe, Chile) greatly improve margins

Magma’s mission: to build a leading pure play geothermal power company Magma’s strategy: broad asset portfolio and scale

= “discovery returns” and “utility returns”

  

Reduces drilling risk and high front-end capital risk Improves margins with lower cost of capital Better multiples DISCOVERY RETURNS UTILITY RETURNS ncome Growth

We are a power company and an energy resource company
