Greentree Gas & Oil Ltd. and Echo Energy Canada Inc. Negotiating Joint Operations

Duncan Hamilton, President of Greentree Gas & Oil Ltd. (TSX VENTURE:GGO)
("Greentree") and Charles Edey, President of Echo Energy Canada Inc. (TSX
VENTURE:EEI) ("ECHO") announced today that they have entered into formal
negotiations about possible joint operations.


Greentree and Echo each recognize that there are opportunities to reduce costs
and improve operating efficiency by sharing management and operational staff and
resources. The parties have agreed to enter into exclusive negotiations with
each other regarding contractual arrangements for sharing of staff and
resources.


"Our field staffs criss-cross each other at regular intervals as they service
our contiguous wells, so it makes sense to talk about some form of cost sharing
arrangement," Hamilton said.


Greentree and Echo also recognize that there may be opportunities for even
greater cost reductions and efficiencies if their operations were merged or if
one company were to acquire the gas and oil operating assets of the other, as
this could reduce the significant management, regulatory and compliance costs
currently being incurred by each party.


"With high compliance costs and low gas prices, we want to look at the
significant cost savings that could come from some form of amalgamation or
merger," Edey said.
