Plaintree Systems Inc. Announces Orders of over U.S.D. One Million for its Flood Proof Foundations

OTTAWA, Ontario--(Business Wire)--
Plaintree Systems Inc. (CNSX: NPT), today announced that in the last four months
its Triodetic division has received contracts worth more that 1.0 million
dollars US for the engineering and manufacture of their tubular foundation
system, for application in areas of unstable soil conditions in Alaska Russia
and the Canadian Arctic.

Triodetic`s has a long term relationship with FEMA ( Federal Emergency
Management Agency) for the use of its foundation technology in flood relief
areas. Its innovative foundation system will be featured at the upcoming AIA
(American Institute of Architects) tradeshow later this month in San Francisco,
CA. Triodetic also has long standing relationships with HUD (U.S. Department of
Housing and Urban development) and CMHC (Canada Mortgage and Housing
Corporation).

David Watson, CEO of Plaintree, says that, "At the AIA, Triodetic will highlight
the benefits of this foundation system for applications such as the Louisiana
rebuilding efforts. They are looking for an inexpensive and robust system that
will allow residences to be elevated up to 8 feet above the ground level".

The foundation consists of a galvanized steel frame, which is torsionally stable
and elevates the building above the flood plane between 3 feet and 8 feet. The
tubular frame gives strength to the building and is adjustable to accommodate
uneven terrain. Several hundreds of buildings have been successfully supported
by the Triodetic Multipoint Foundation Frames by over the last 30 years and
growth in this market has been strong.

2009 financial statements together with the related Management`s Discussion and
Analysis report, copies of which can be obtained from the Company`s website at
