Dear Jeremy:

I am sending this letter to inform you that I must submit my resignation from
the MTI Board of Directors effective immediately.

My business and its demands are making it impossible for me to do any justice to
MTI as a board member.

I remain very positive and stand ready to assist when I can.

Sincerely,


/s/ Thomas R. Penaluna
