I herein tender my  resignation  as director of SensiVida  Medical  Technologies
Inc. to be effective immediately. I have no disagreement with the Company on any
matter relating to the Company's  operations,  policies or practices.  Given the
state of the art  technical  nature and  intellectual  demands  of  management's
present  technology  I do not  believe  it to be in  the  best  interest  of the
company's  shareholders,  of which I am one, to continue as a director.  I am 76
years of age well past 70/72 the strongly  recommended  corporate retirement age
and have served as a board member since 1981, and Chief  Executive  Officer from
1993 to the  completion of the merger  November  2008.  (See 8-K Nov 12, 2008) I
shall continue to assist  management  professionally  when requested as retained
independent counsel.

Thanks and best wishes to the entire SensiVida group.
