Dear Chris:
I am looking forward with much anticipation to collaborating with you to
demonstrate the degree to which Signal Advance technology will improve the
performance of my own technology - repetitive EEG-Driven Light and Sound
Stimulation (rEDLSS) neuro-therapy systems. I expect the reduced response
delay will markedly increase treatment efficacy, thereby decreasing the amount
of time required to produce significant and long lasting increases in children
memory and cognitive abilities as indicated by IQ test scores. Increased
scores on IQ tests are usually thought to be indicative of an increased
ability to learn and perform well in school.

Increased effectiveness resulting from the incorporation of Signal Advance
technology could significantly improve the precision of the stimulation,
improving treatment efficiency and thus, significantly decrease treatment
time. The direct cost of EDLSS treatment could then become even more
affordable to most schools and parents.

It is my belief that Signal Advance technology will likely be seen as a
disruptive technology that forces rapid change in the field of biomedical
instrumentation with early adopters of this technology gaining a significant
commercial advantage over later adopters in the same field.

I am pleased to be able to be a part of and support the development and
 implementation of Signal Advance technology.
