Duffy -

I agree, though I do think that the exposure associated with ringing the bell for a very small and newly up listed company such as Sigma could be of significance.

Thanks for your response earlier re your husband's engineering background. You asked if there is anything in particular that I'm trying to understand and am facing limitations due to a lack of understanding of engineering.

I don't know that there is any one question at this time -- it's more an overall sense of personal limitation in fully evaluating Sigma's position in the industry from a technology point of view.

Any thoughts are appreciated.

Thank you
