(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 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 Pirelli's Statement on Schedule 13D). On January 23, 2004, the parties to the Hopa Agreement entered into an agreement to amend the Hopa Agreement (the "Hopa Agreement Amendment"). The Hopa Agreement Amendment relieves Hopa of certain restrictions contained in the Hopa Agreement relating to Hopa's ownership of Telecom Italia Shares in order to permit Hopa to enter into a transaction with Nexgen Capital Limited pursuant to which Hopa will receive 229,411,021 Telecom Italia Shares in exchange for certain derivative instruments whose value is linked to the performance of Telecom Italia Shares. A copy of an English translation of the Hopa Agreement Amendment is filed as Exhibit to Amendment No. 27 to Pirelli's Schedule 13D, dated January 23, 2004, filed as Exhibit 43 to this Schedule 13D and incorporated by reference herein.
