                  (iv)  on October 1, 2006, the remaining principal balance that
         has not been repaid prior thereto by the Executive pursuant to clauses
         (i) - (iii) above, or extinguished and forgiven as provided below,
         shall become due and payable.

         If (i) the Executive's employment terminates prior to October 1, 2006
for any reason other than a reason set forth in clause (ii) or clause (iii)
above, or (ii) the Executive becomes entitled to severance compensation under
any special termination agreement between the Executive and the Company relating

Executive, in whole or in part, at any time or from time to time, without
penalty.
