         This Amendment No. 4 amends the Statement on Schedule 13D, dated
October 19, 2001, as amended (as previously amended, the "Statement on Schedule
13D"), filed by IntesaBci S.p.A., a company organized under the laws of the
Republic of Italy ("BCI"), 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.

         BCI, Pirelli, Edizione Holding, UniCredito 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.
