         This Amendment No. 12 amends the Statement on Schedule 13D, dated
October 25, 2001, as amended (as previously amended, the "Statement on Schedule
13D"), filed by UniCredito Italiano S.p.A., a company organized under the laws
of the Republic of Italy ("UniCredito"), 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.

         UniCredito, Pirelli, Edizione Holding, IntesaBci S.p.A. (now Banca
Intesa S.p.A.) ("Intesa"), Olimpia S.p.A. ("Olimpia") and, as discussed in Items
4 and 6 of Amendment No. 6 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 UniCredito in
accordance with Rule 13d-1(k)(2) under the Securities Exchange Act of 1934, as
amended.

Item 2.  IDENTITY AND BACKGROUND

         As reported in Amendment No. 10 to the Statement on Schedule 13D, Mr.
Emilio Gnutti became a director of Olimpia on May 5, 2003. Mr. Gnutti's present
principal occupation is entrepreneur and his business address is Corso
Zanardenelli 32, Brescia, Italy. Mr. Gnutti is an Italian citizen.

         Olimpia and Pirelli have been informed that, during the past five
years, Mr. Gnutti has not been (i) a party to a civil proceeding of a judicial
or administrative body of competent jurisdiction as a result of which he was or
is subject to a judgment, decree or final order enjoining future violations of,
or prohibiting or mandating activity subject to, federal or state securities
laws on finding any violation with respect to such laws, or (ii) convicted in
any criminal proceeding (excluding traffic violations or similar misdemeanors),
except that on June 25, 2002, Mr. Gnutti was convicted in the Tribunale Brescia
of charges based on Article 180, Paragraph 1(b) of Legislative Decree 58 of
February 24, 1998 - Consolidated Law on Financial Intermediation, in connection
with which Mr. Gnutti was fined euro 100,000 and sentenced to serve eight months
in prison. (Article 180, Paragraph 1(b) relates to the unauthorized disclosure
of inside information - the charges do not relate to conduct involving the
securities of Telecom Italia, Olivetti or Pirelli.) An appeal by Mr. Gnutti from
the decision of the Tribunale Brescia is presently pending in the Court of
Appeal of Brescia.

issued a press release which reports (among other things) that a maximum total
amount of euro 8,989,059,475 will be allocated to the tender offer for Telecom
Italia Shares and Telecom Italia Savings Shares. Specifically, the press release
reports that Olivetti will publicly tender for (i) 908,873,776 Telecom Italia
Shares (representing approximately 17.3% of the total number of outstanding
securities of that class) at a price per share of euro 8.01) and (ii)
354,560,274 Telecom Italia Savings Shares (representing approximately 17.3% of
the total number of outstanding securities of that class) at a price per share
of euro 4.82. A copy of the press release is filed as an Exhibit to Amendment
No. 20 to Pirelli's Schedule 13D, dated July 14, 2003, filed as Exhibit 35 to
this Schedule 13D and incorporated by reference herein. On June 19, 2003,
Olivetti issued a press release which reports that Olivetti received
authorization from Consob on June 18,

                                       3

Italia Shares and Telecom Italia Savings Shares. The press release also reports
that the take-up period for the tender offer will run from 08:30 (Italian time)
on June 23, 2003 until 17:40 (Italian time) on July 18, 2003. A copy of the
press release is filed as an Exhibit to Amendment No. 20 to Pirelli's Schedule

(representing, in each case, less than 0.1% of the total number of securities of
that class), which are held of record by Mr. Gnutti's wife, Ms. Ornella Pozzi.
