Dear Yevsey,

This is in response to your inquiry concerning SEC questions as to my participation in preparation and filing of U.S. utility and PCT applications in June of 2004.

I did prepare and file these applications and I have no objections to making such a representation, including my name, to the SEC.

If you have any further questions in this regard, please do not hesitate to contact me.

Sincerely,

/s/ Edward D. Pergament
