     discharging the obligations imposed on them and on certain investment 
     companies with variable capital ("ICVCs") by the said Section and arising 
     out of the transaction referred to in paragraph 3 below.

3.   Following the recent conversion of unit trusts to ICVCs they ceased to be

     ICVC named below had a notifiable interest (within the meaning of Section

     name, the registered holders of such shares being as also indicated below:-
