Press Release Summary = The Patent Office of the United Kingdom has announced the
revocation of European patent EP(UK) 0353376 entitled "Burnishing Tool" and assigned
to Ecoroll AG Werkzeugtechnik of Germany. The decision to revoke EP(UK) 0353376 was
based on Ecoroll's failure to promptly seek leave to amend the European application
in view of prior art that Ecoroll was made aware of during the prosecution of the
equivalent U.S. application.

Press Release Body = Cincinnati, Ohio - May 10, 2007 -The Patent Office of the
United Kingdom has announced the revocation of European patent EP(UK) 0353376
entitled "Burnishing Tool" and assigned to Ecoroll AG Werkzeugtechnik of Germany.
The decision to revoke EP(UK) 0353376 was based on Ecoroll's failure to promptly
seek leave to amend the European application in view of prior art that Ecoroll was
made aware of during the prosecution of the equivalent U.S. application.

The revocation of EP(UK) 0353376 eliminates any impediment to Lambda's patented Low
Plasticity Burnishing (LPB) Technology and associated tooling and sets the stage for
Lambda to enter the European market.

LPB is a proven surface treatment that develops a deep layer of high magnitude
compressive residual stress (RS) to mitigate fretting fatigue, corrosion fatigue, or
fatigue from foreign object damage (FOD) in the fatigue prone areas of expensive and
critical aircraft components such as landing gear, propeller hubs, and turbine
engine blades.

Unlike other burnishing or \"deep rolling\" methods, LPB involves a single pass of a
smooth, free rolling spherical ball tool used under a normal force sufficient to
deform the surface of the material, creating a thermally and mechanically stable
layer of compressive residual stress with controlled or minimized plastic
deformation. Application of LPB delivers significant fatigue life extension with
minimal initial capital investment and low production costs.

Lambda Technologies is an innovative company incorporating a premier materials
research laboratory with a world-class engineering and production enterprise
dedicated to the development and optimization of surface treatments to improve
component performance. For additional information on Lambda Technologies or
