AG called Michelle Walker and received the following answers to the questions provided in the 3/11/09 contact report.

Ms. Walker will follow- up with Nanocyl for a further explanation on this. She will see if estimates are known for how many campaigns/year and/or days/year a customer would use the CNTs.
