Capitalized terms used in this Amendment without definition have the meanings ascribed to them in the Statement on Schedule 13D. UniCredito, Pirelli, Edizione Holding, BCI and the Purchaser are members of a group with respect to the Telecom Italia Shares. This Amendment constitutes a separate filing on Schedule 13D by BCI in accordance with Rule 13d-1(k)(2) under the Securities Exchange Act of 1934, as amended. Item 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. On November 22, 2001, 492,495,499 of the Olivetti Shares, and 492,495,501 of the Olivetti Convertible Bonds, that the Purchaser acquired pursuant to the Olivetti rights offering were pledged to Banca di Roma as security agent under the pledge agreement that was filed with Amendment No. 2 to the Statement on Schedule 13D as Exhibit 16. As reported in Item 3 of Amendment No. 2 to the Statement on Schedule 13D, the pledge agreement secures the Purchaser's borrowings under the Revolving Facility Agreement (a copy of which was filed with Amendment No. 2 to the Statement on Schedule 13D as Exhibit 15). On November 27, 2001, Article I and paragraph 10(a) of the instrument governing the bonds issued by the Purchaser to Bell on October 5, 2001 (a copy of which was filed with the Statement on Schedule 13D as Exhibit 7) were amended to, among other things, provide a formula for making anti-dilution adjustments to the number of Olivetti Shares to be delivered to the bondholder upon retirement of the bonds. A copy of the amended provisions is filed as Exhibit 22. Item 5. INTEREST IN SECURITIES OF THE ISSUER. (a) As reported in Item 5(a) of Amendment No. 3 to the Statement on Schedule 13D, after giving effect to the Purchaser's acquisition of 504,825,563 Olivetti Shares and 504,825,562 Olivetti Convertible Bonds pursuant to the Olivetti rights offering, the Purchaser directly holds 2,524,127,813 Olivetti Shares, 504,825,562 Olivetti Convertible Bonds (each of which is convertible into one Olivetti Share at any time during the period between January 22, 2002 and December 15, 2009) and 68,409,125 Olivetti Warrants (each of which may be exercised into 0.5 Olivetti Shares at any time until December 15, 2002). In addition, after giving effect to the transactions described in Item 5(c) of Amendment No. 3 to the Statement on Schedule 13D, the Purchaser has the right to acquire a further 263,500,000 Olivetti Shares, and Pirelli has the right to acquire a further 300,000,000 Olivetti Convertible Bonds or Olivetti Shares. On December 13, 2001, Olivetti reported to the Companies Registry of Turin that, as of that date, there were 8,783,701,564 Olivetti Shares issued and outstanding. The Purchaser's direct holding of 2,524,127,813 Olivetti Shares represents 28.74% of the total number of Olivetti Shares reported to be outstanding. This percentage assumes that the Purchaser has not converted any of its Olivetti Convertible Bonds, exercised any of its Olivetti Warrants or acquired any Olivetti Shares in connection with the transactions described Item 5(c) of Amendment No. 3 to the Statement on Schedule 13D.
