(which, as reported in Amendment No. 21 to the Statement on Schedule 13D, subsequently merged with and into Pirelli & C. S.p.A., a company incorporated under the laws of the Republic of Italy), and, commencing with Amendment No. 1 thereto, Olimpia S.p.A., a company incorporated under the laws of the Republic of Italy, with respect to the ordinary shares, euro 0.55 par value per share, of Telecom Italia S.p.A., a company incorporated under the laws of the Republic of Italy. Capitalized terms used in this Amendment without definition have the meanings ascribed to them in the Statement on Schedule 13D. Pirelli & C., Olimpia, Edizione Holding and Edizione Finance, UCI and BCI are members of a group with respect to the Telecom Italia Shares. This Amendment constitutes a separate filing on Schedule 13D by Pirelli & C. and Olimpia in accordance with Rule 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, except that information contained in the Statement on Schedule 13D concerning any director or officer of Olimpia nominated by Edizione Holding and Edizione Finance, UCI or BCI has been provided by the nominating person or by such nominee director or officer. ITEM 3. SOURCE AND AMOUNT OF FUNDS AND OTHER CONSIDERATION Reference is made to the Share Forward Agreement (as that term is defined in Item 5 of Amendment No. 41 to the Statement on Schedule 13D). On August 14, 2006, Pirelli Finance (Luxembourg) S.A. ("PFL"), a wholly-owned subsidiary of Pirelli & C., purchased 134,957,885 Telecom Italia Shares from Banca Caboto S.p.A. ("Caboto") for an aggregate cash purchase price of (euro)312,013,048 pursuant to the Share Forward Agreement, thereby terminating, and settling the respective obligations of the parties under, such agreement. PFL obtained the purchase price from its own available cash resources. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER The information contained in Item 3 above is incorporated herein by reference. The acquisition by PFL of 134,957,885 Telecom Italia Shares as described in Item 3 above does not result in any change to the number of Telecom Italia Shares beneficially owned by Pirelli & C. As described in Item 5 of Amendment No. 41 to the Statement on Schedule 13D, such shares were deemed to be beneficially owned by Pirelli & C. on the date on which the Share Forward Agreement was entered into.
