Definitive Agreement Signed With
Greentree Gas And Oil Ltd.

EDMONTON, Alta February 2, 2006/ Wavefront Energy and Environmental Services Inc., a provider of innovative technologies for increased oil production and groundwater remediation and Greentree Gas and Oil Ltd. (TSX-V: GGO) an exploration and production company in southwestern Ontario, are pleased to announce that they have entered into a Definitive Agreement to develop Greentree’s Rodney South, Ontario oil field lease using Wavefront’s DeepWave^SM (http://onthewavefront.com/dw_what-is-deep-wave.htm) Technology.

Under the terms of the Definitive Agreement Wavefront will provide up to $C 2.25 million for capital expenditures related to initial field development. Greentree will act as the Operator of the lease and will contribute the petroleum leases, existing seismic and geological data, field staff, and the use of its production facilities. Current development plans are tentatively scheduled to commence as soon as permits are in place. The approach to exploitation of Rodney South is similar to that of Rogers County, OK using horizontal producers straddled by vertical DeepWave^SM water injectors. The Rodney South oil field lease has an estimated 3.65 MMStb of oil in place and can be expected to recover 1.33 MMStb if fully developed by standard waterflooding. It is anticipated that with the implementation of DeepWave^SM during flooding, in excess of 2 MMStb of oil may be producible.

In consideration of Wavefront’s capital investment it shall earn a 70% net overriding royalty interest in the production from all new wells as well as from nine wells currently operated by Greentree until payout of Wavefront’s initial $C 2.25 million capital investment. Subsequent to payout, cash flow from operations will be allotted 50% to each of Wavefront and Greentree.

Brett Davidson, President and CEO of Wavefront commented, “The agreement with Greentree represents further opportunity for the Company to demonstrate the strength of its technology on what would be considered a marginal field. Wavefront is pleased to be working with a credible, and forward looking operator such as Greentree who are breaking new ground in Canada by implementing DeepWave^SM on a large scale. With each new agreement we are securing our vision of making DeepWave^SM the injection technology of choice in the energy, environmental, and mining sectors. We continue to pursue opportunities to showcase DeepWave^SM and build shareholder value.”

Duncan Hamilton, President of Greentree stated, “We are anxious to commence development of the Rodney South pool utilizing Wavefront’s DeepWave^SM technology. The Rodney South pool is directly adjacent to the second largest oil pool in Ontario, which has produced over 10.5 million barrels of light oil from the same geological formation using 1960’s water injection technology and vertical producers. Greentree is confident that with the benefit of horizontal producers and DeepWave^SM in Rodney South, a higher percentage of the oil in place will be recoverable at a much-accelerated rate of production”.
