(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 The information contained in Item 6 below is incorporated herein by reference. On July 12, 2006, Pirelli & C. purchased from Hopa certain shares of Olimpia representing 12.8% of Olimpia's total issued and outstanding share capital (and comprising 80% of Hopa's 16% stake in Olimpia) for a purchase price of approximately (euro)497,600,000. Pirelli & C. obtained the purchase price from its wholly-owned subsidiary, Pirelli Finance (Luxembourg) S.A., which in turn obtained the funds from its own available cash resources. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER The information contained in Item 6 below is incorporated herein by reference. ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER Reference is made to the Hopa Agreement (as that term is defined in Item 6 of Amendment No. 17 to the Statement on Schedule 13D) and to the information relating thereto reported in Amendments No. 39 and 41 to the Statement on Schedule 13D. On July 12, 2006, Pirelli & C. purchased 80%, and Edizione Finance and Edizione Holding purchased the remaining 20%, of Hopa's 16% stake in Olimpia for an aggregate cash purchase price of approximately (euro)622,000,000. After giving effect to those transactions, the share capital of Olimpia is held by Pirelli & C., Edizione Finance (together with Edizione Holding), UCI and BCI in the following respective proportions: 70.46%, 20%, 4.77% and 4.77%. Page 4 of 7 pages Also on July 12, 2006, (i) Hopa purchased all of Olimpia's 19.999% stake in Holinvest for a cash purchase price of approximately (euro)86,000,000 and (ii) Olimpia and Holinvest executed a letter agreement (the "Holinvest Agreement") which places certain restrictions on Holinvest's ability to acquire or dispose of Telecom Italia Shares for a period of two years. Under the Holinvest Agreement, Holinvest grants to Olimpia a right of first refusal in connection with any proposed transfer by Holinvest of Telecom Italia Shares (i) to the extent that such transfer would result in Holinvest owning less than approximately 65% of the total number of Telecom Italia Shares that it owned as of July 12, 2006 or (ii) if, at the time of such proposed transfer, Holinvest owns less than approximately 65% of the number of Telecom Italia Shares that it owned as of July 12, 2006. Also, under the Holinvest Agreement, Holinvest (and, for so long as Hopa controls Holinvest, Hopa) is prohibited from acquiring any additional Telecom Italia Shares without the prior consent of Olimpia, provided that (i) Olimpia may not unreasonably withhold such consent with respect to any proposal to acquire up to an additional 1% in aggregate of the total number of issued and outstanding Telecom Italia Shares and (ii) Olimpia's consent is not required in respect of any acquisition by Holinvest of Telecom Italia Shares if, after giving effect to such acquisition, Holinvest's holding of Telecom Italia Shares would not exceed 3.68% of the total number of issued and outstanding Telecom Italia Shares. An English translation of the Holinvest Agreement is filed as Exhibit 99. On each of July 4, 2006 and July 12, 2006, Pirelli & C., Edizione Finance, Edizione Holding and Hopa issued a joint press release concerning the transactions described above in this Item 6.
