 provision  of  this  paragraph  shall  control  and  supersede  every  other
 provision of all agreements between the undersigned and the holder hereof.

 the  Internal  Revenue  Code  of  1986,  as  amended  (the  "Code")  and  is

 issuance by the issuer of  a new instrument to  the new holder. Transfer  of
 this instrument at any time by any means other than the method described  in
 this paragraph shall be deemed void  and ineffectual. This instrument  shall
 not be convertible to bearer form.
