(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 are members of a group with respect to the Telecom Italia Shares. (By virtue of the 2006 Shareholders Agreement described in Amendment No. 45 to the Statement on Schedule 13D, Assicurazioni Generali S.p.A. and Mediobanca S.p.A. may also be deemed to be members of that group.) 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 or Edizione Finance has been provided by the nominating person or by such nominee director or officer. ITEM 2. IDENTITY AND BACKGROUND On December 19, 2006, a shareholders' meeting of Olimpia resolved to amend the by-laws of Olimpia by (a) reducing the size of the board of directors from ten to six (and limiting the number of directors that may be drawn from any individual shareholder's list of nominees to half of the total number of directors) and (b) reducing to 81 percent the proportion of the total number of Olimpia shares required to be (i) represented at an extraordinary shareholders meeting in order to constitute a quorum and (ii) affirmatively voted in order to approve any resolution at an extraordinary shareholders meeting. Also at the shareholders' meeting of Olimpia, each of the following individuals was elected to the board of directors for a term of three fiscal years: Mr. Marco Tronchetti Provera, Mr. Carlo A. Puri Negri, Mr. Luciano Gobbi, Mr. Gilberto Benetton, Mr. Gianni Mion and Mr. Giancarlo Olgiati. Each of Messrs. Tronchetti Provera, Puri Negri and Gobbi was nominated by Pirelli & C., and each of Messrs. Benetton, Mion and Olgiati was nominated by Edizione Holding and Edizione Finance. (Subsequently, at a meeting of the Olimpia's board of directors held on the same date, Mr. Tronchetti Provera was confirmed as Chairman of Olimpia and Mr. Benetton was confirmed as Vice-Chairman of Olimpia.) Information concerning each of Messrs. Tronchetti Provera, Puri Negri, Gobbi, Benetton and Mion has previously been filed on this Statement on Schedule 13D. Mr. Olgiati's present principal occupation is partner of the Swiss law firm of Ghiringhelli, Olgiati e Asssociati and his business address is Via Nassa 38, 6900 Lugano, Switzerland. Mr. Olgiati is a Swiss citizen. He does not beneficially own any securities of Telecom Italia. Page 4 of 7 pages During the past five years, to the knowledge of Pirelli & C. and Olimpia, Mr. Olgiati has not been (i) convicted in any criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction as a result of which he was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activity subject to, federal or state securities laws or finding any violation with respect to such laws. A copy of a press release issued by Olimpia in connection with the December 19, 2006 shareholders' meeting is filed as Exhibit 107. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER Reference is made to the swap transaction between Pirelli & C. and Credit Agricole Lazard Financial Products Bank ("Calyon") described in Item 5 of Amendment No. 7 to the Statement on Schedule 13D (the "Calyon Swap Transaction").
