(now Banca Intesa S.p.A.), a company organized under the laws of the Republic of Italy ("Intesa"), 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. Intesa, Pirelli, Edizione Holding, UniCredito, Olimpia S.p.A. ("Olimpia") and, as discussed in Items 4 and 6 of Amendment No. 7 to the Statement on Schedule 13D, Hopa S.p.A. ("Hopa") are members of a group with respect to the Telecom Italia Shares. This Amendment constitutes a separate filing on Schedule 13D by Intesa in accordance with Rule 13d-1(k)(2) under the Securities Exchange Act of 1934, as amended. ITEM 3. SOURCE AND AMOUNT OF FUNDS AND OTHER CONSIDERATION Reference is made to Item 4 of Amendment No. 25 to Pirelli's Schedule 13D. On December 18, 2003, Olimpia purchased 294,750,000 Telecom Italia Shares from Mediobanca at a price per share of euro 2.37 pursuant to the agreement entered into by Olimpia and Mediobanca on November 5, 2003. Olimpia obtained the purchase price from capital contributed by its shareholders, as reported in Item 4 of Amendment No. 25 to Pirelli's Schedule 13D. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER After giving effect to the acquisition of the 294,750,000 Telecom Italia Shares referred to in Item 3 (all of which are beneficially owned by Intesa with shared voting power and shared dispositive power), Intesa beneficially owns 1,770,615,593 Telecom Italia Shares, representing approximately 17.19% of the total number of outstanding Telecom Italia Shares. By virtue of its ownership of 8.4% of the outstanding shares of capital stock of Olimpia as of December 31, 2003, Intesa may be deemed to beneficially own all shares of Telecom Italia beneficially owned by Olimpia. (a) As of December 31, 2003, Intesa and its subsidiaries owned 12,537,742 Telecom Italia Shares, and held as pledgee, with a right to vote, 18,849,770 Telecom Italia Shares. (b) Intesa has sole power to vote or to direct the power to vote 18,849,770 Telecom Italia Shares that have been pledged to Intesa in connection with loan transactions entered into in the ordinary course of Intesa's banking business. Intesa has the sole power to vote and dispose of 12,537,742 Telecom Italia Shares. (c) Except as disclosed in Item 3 of the Statement on Schedule 13D and other than pledge transactions entered into in the ordinary course of Intesa's banking activities, Intesa has not effected any transaction in Telecom Italia Shares during the past 60 days. After giving effect to the acquisition of the 294,750,000 Telecom Italia Shares referred to in Item 3, Olimpia beneficially owns 1,751,765,823 Telecom Italia Shares, representing approximately 17.01% of the total number of outstanding Telecom Italia Shares. 3 ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER Reference is made to the New Partners Agreement (as that term is defined in Item 3 of Amendment No. 2 to Pirelli's Schedule 13D). On December 16, 2003, Pirelli, UniCredito and Intesa entered into an agreement to amend the New Partners Agreement (the "New Partners Agreement Amendment"). Pursuant to the New Partners Agreement Amendment, each of UniCredito and Intesa agrees to fully subscribe for its proportional share of Olimpia Shares in connection with the capital increase described in Item 4 of Amendment No. 25 to Pirelli's Schedule 13D (such shares, the "New Shares"). In addition, the New Partners Agreement Amendment modifies in certain respects the manner in which the purchase price to be paid by Pirelli for the New Shares is to be determined in the event that any such shares are transferred to Pirelli pursuant to the New Partners Agreement. A copy of the New Partners Agreement Amendment and a copy of a joint press release issued by Pirelli, UniCredito and Intesa concerning the New Partners Agreement Amendment are filed as Exhibits 58 and 59, respectively, to Pirelli's Schedule 13D, dated December 18, 2003, and are filed as Exhibits 41 and 42, respectively, to this Schedule 13D and incorporated by reference herein. 4 ITEM 7.
