                      the provisions contained in this Agreement which shall
                      continue for a period of thirty (30) days after written
                      notice has been given to the Executive by the Corporation;

               (iii)  if the Executive shall become an alcoholic or drug addict;

               unable to perform his duties and obligations pursuant to this
               Agreement. For the purposes of this Agreement, once any period of

               occurred, no new consecutive period of illness on the Executive's
               part shall be deemed to have commenced unless the Executive shall
               have returned to the performance of his duties and obligations
               pursuant to this Agreement for thirty (30) consecutive days
               following any previous consecutive period of illness.

hereunder, or at any time thereafter, disclose to any person, firm or
corporation, any confidential information concerning the business or affairs of
the Corporation. Confidential information shall not include any information
