(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) ("PIRELLI"), and, commencing with Amendment No. 1 thereto, Olimpia S.p.A. ("OLIMPIA"), 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, Olimpia, Sintonia S.p.A. (which, it publicly announced on March 9, 2007, has replaced Edizione Holding in various shareholders agreements relating to Olimpia) and Sintonia S.A. (which, according to Sintonia S.p.A.'s public announcement, is the new name of Edizione Finance) are members of a group with respect to the Telecom Italia Shares. This Amendment constitutes a separate filing on Schedule 13D by Pirelli and Olimpia in accordance with Rule 13d-1(k)(2) under the Securities Exchange Act of 1934. Pirelli 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 Sintonia S.p.A., its predecessor Edizione Holding or Sintonia S.A. has been provided by the nominating person or by such nominee director or officer. ITEM 4. PURPOSE OF TRANSACTION The information contained in Items 5 and 6 below is incorporated herein by reference. A copy of the joint press release issued by Pirelli and Sintonia S.p.A. and Sintonia S.A. (collectively, the "SINTONIA SELLERS") announcing the transaction is filed as Exhibit 114 and incorporated herein by reference. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER On May 4, 2007, Pirelli and the Sintonia Sellers entered into a Stock Sale Purchase Agreement (the "SHARE PURCHASE AGREEMENT") with Telefonica S.A., Assicurazioni Generali S.p.A. ("GENERALI"), Sintonia S.A. (in its capacity as buyer), Intesa Sanpaolo S.p.A. and Mediobanca S.p.A. ("MEDIOBANCA") (collectively, the "PURCHASERS") for the sale of 100% of the share capital of Olimpia (the "OLIMPIA SHARES"). Information contained in Item 6 below concerning the Share Purchase Agreement is incorporated herein by reference. Page 4 of 8 ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIP WITH RESPECT TO SECURITIES OF THE ISSUER The summary of certain material provisions of the Share Purchase Agreement below does not purport to be a full and complete description of such document and is entirely qualified by reference to the full text of such document attached as Exhibit 115, which is incorporated herein by reference. Pursuant to the Share Purchase Agreement, in consideration for 100% of the share capital of Olimpia, the Purchasers have agreed to pay a total amount of euro 2.82 per Telecom Italia share multiplied by 2,407,345,359 Telecom Italia shares, less Olimpia's total net debt (as defined under the Share Purchase Agreement) as of the closing date. The provisional purchase price for 100% of Olimpia's share capital is expected to be approximately euro 4.1 billion. The Share Purchase Agreement provides, among other things, that (i) the Olimpia Shares will be purchased and sold with the right of the Purchasers to receive any dividends distributed by Olimpia after the closing of the transaction, even if accrued prior to the closing and (ii) the completion of the purchase of the Olimpia Shares is subject to approval and authorizations by competent authorities. In addition, Pirelli and the Sintonia Sellers have agreed that between the date of the Share Purchase Agreement and the closing of the transactions contemplated thereby: o Pirelli and the Sintonia Sellers will not enter into any agreement which may affect the title or transferability of the Olimpia Shares; o the Olimpia by-laws will not be amended; o Olimpia will not issue any shares, pay any dividends or otherwise carry out any extraordinary corporate transaction; and o Olimpia will, in general, conduct its business in the ordinary course and consistently with past practice. The Share Purchase Agreement provides that, upon the closing of the transaction, (i) Olimpia, Pirelli, the Sintonia Sellers and the relevant Purchasers shall terminate all existing shareholders' agreements concerning Olimpia and Telecom Italia, including the "Shareholders Agreement" (as defined in the Schedule 13D filed on August 9, 2001) and the shareholders' agreement dated as of October 18, 2006, entered into between Pirelli, Edizione Holding, Olimpia, Generali and Mediobanca, and (ii) three directors of Telecom Italia designated by Pirelli will resign from the Board.
