About T-Ray Science, Inc.

T-Ray has exclusive rights to platform technology and is developing a Skin Cancer Imaging device which utilizes the unique properties of TeraHertz waves (THz). The Company is developing a new THz sensing and imaging technology that would constitute a new modality of medical imaging with potentially expanding applications in other areas of cancer imaging. THz waves lie in the frequency range between micro waves and infrared waves on the electromagnetic spectrum. T-Ray Science, Inc. seeks to harness the power of THz waves, to develop revolutionary new medical imaging products.

The Company has built an expertise and industry reputation for its ability to design, simulate and manufacture THz sources and detectors which are a critical component for THz based devices. These THz sources and detectors are on a semi-conductor substrate and are also called THz chips. The Company has a catalogue of THz chips and has already sold THz chips to leading universities and National Laboratories in an effort to increase our revenue and brand awareness. The Company has the ability to react to potential changes in the technological landscape by adapting and designing THz sources and detectors that work in either continuous or pulsed wave at varying frequencies. This gives T-Ray a powerful competitive advantage in the development of THz based devices.

The Company also has a Tablet Analyser for pharmaceutical applications such as drug authentication under development. The Center for Medicines in the Public Interest in the USA predicts that counterfeit drug sales could reach US$ 75 billion globally in 2010 if action is not taken to curb the trade. T-Ray offers a solid state, portable, low cost, easy to use, point of care solution, which is patented and in final production engineering with Sanmina SCI. The Company plans to have the first 12 production units ready for final testing and approvals in early 2010.
