          belief, the securities referred to above were acquired and are

          are not held for the purpose of or with the effect of changing or       
          influencing the control of the issuer of the securities and were not    
          acquired and are not held in connection with or as a participant

          solely in connection with a nomination under (s) 240.14a-11.

          scheme applicable to insurance companies in Canada
