            This Amendment No. 46 amends the Statement on Schedule 13D, dated
August 9, 2001, as amended (as previously amended, the "Statement on Schedule

13d-1(k)(2) under the Securities Exchange Act of 1934. Pirelli & C. and Olimpia
are responsible solely for the information contained in their separate filing,
