About CTC:

Composite Technology Corporation, based in Irvine, California, USA develops, manufactures and sells innovative high performance electrical transmission and renewable energy generation products through its subsidiaries:

--  CTC Cable Corporation produces composite rod for use in its patented
    ACCC (aluminum conductor composite core) conductors, which are "high
    efficiency conductors" for use in electrical transmission grid systems.
    ACCC conductors demonstrate less electricity line losses when compared with
    conventional conductors. When deployed in place of conventional conductors
    on existing systems, the higher efficiency of ACCC conductors enable power
    generators to reduce the amount of power they must generate while still
    delivering the same power to the customers. They have also demonstrated
    significant savings in upgrade capital costs and operating expenses when
    substituted for other conductors. ACCC conductors enable grid operators to
    reduce blackouts and brownouts, providing a 'reserve electrical capacity'
    by operating at higher temperatures without significant thermal sag of the
    lines. ACCC conductors are an innovative economical solution for
    reconductoring power lines, constructing new lines and crossing large
    spans. ACCC composite rod is delivered to qualified conductor manufacturers
    worldwide for local ACCC conductor production and resale into local
    markets.

--  DeWind Inc. designs, produces, and sells the DeWind series of wind
    energy turbines including the new D8.2 model rated at 2 megawatts (MW)
    available in both 50Hz and 60Hz; the D8 model rated at 2 MW available in
    50Hz; and the D6 model rated at 1.25 MW available in 50Hz. The new D8.2,
    which has been operating since early 2007 at Cuxhaven, Germany, utilizes
    the advanced WinDrive® hydrodynamic torque converter developed by Voith
    AG with a synchronous AC generator that is able to connect directly to the
    grid at high voltage without the use of power conversion electronics.
    During the 3rd quarter of 2007, a 60Hz version will be installed at a site
    in the USA for certification. In late 2007, the first D8.2 turbines are to
    be assembled at TECO Westinghouse Motor Company in Texas, which will supply
    turbines for our North and South American customers.
