Republic of Italy  ("Pirelli"),  and,  commencing  with Amendment No. 1 thereto,
Olimpia S.p.A., a company  incorporated  under the laws of the Republic of Italy
(the "Purchaser" or "Olimpia"),  with respect to the ordinary shares,  euro 0.55
par value per share, of Telecom Italia S.p.A., a company  incorporated under the

           Pirelli, the Purchaser,  Edizione Holding, UCI, BCI and, as discussed
in Items 4 and 6 of Amendment  No. 14 to the Statement on Schedule 13D, Hopa are
members of a group with respect to the Telecom  Italia  Shares.  This  Amendment
constitutes  a separate  filing on Schedule 13D by Pirelli and the  Purchaser in
accordance  with Rule  13d-1(k)(2)  under the  Securities  Exchange Act of 1934.
Pirelli and the Purchaser are responsible  solely for the information  contained
in their separate filing,  except that information contained in the Statement on
Schedule 13D  concerning  any director or officer of the Purchaser  nominated by
Edizione Holding, UCI, BCI or Hopa has been provided by the nominating person.
