Dear Dom,

I am writing to inform you of my decision to resign my position on the Board

of Sanomedics, effective immediately.

My other commitments have become too great for me to be able to fulfill the

requirements of my position on the Board.

If I can be of any assistance during the time it will take to fill the position,

please don't hesitate to ask.

Best Regards,

/s/ Charlie Alvarez
