            This Amendment No. 21 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. (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 4.  PURPOSE OF TRANSACTION
         ----------------------

         On January 23, 2005, Olimpia announced that it had entered into a
forward sale agreement (the "Mediobanca Forward Sale Agreement"), dated as of
December 24, 2004, with Mediobanca S.p.A. ("Mediobanca") pursuant to which
Olimpia agrees to purchase from Mediobanca certain Telecom Italia Shares for an
aggregate purchase price of 410,000,000 euro, subject to the conditions
described below in this paragraph. The purchase price per Telecom Italia Share
will be determined by reference to the price paid by Mediobanca to acquire such
Telecom Italia Shares during the term of the Mediobanca Forward Sale Agreement
(subject to minor adjustments to reflect transaction costs that may be incurred
by Mediobanca), but will not in any event exceed 3.50 euro. The number of
Telecom Italia Shares to be acquired by Olimpia pursuant to the Mediobanca
Forward Sale Agreement will be determined by dividing 410,000,000 euro by the
price per Telecom Italia Share determined in accordance with the previous
sentence. If the weighted average market price of Telecom Italia Shares exceeds
3.50 euros for any seven consecutive trading days during the term of the
Mediobanca Forward Sale Agreement, then either party may convene a meeting with
the other party for the purpose of renegotiating the terms of the purchase and
sale of the Telecom Italia Shares. If the parties are unable to reach an
agreement within five trading days following the date of such meeting, then
Mediobanca may elect to terminate the Mediobanca Forward Sale Agreement. In
addition, settlement of the transactions contemplated by the Mediobanca Forward
Sale Agreement is conditional upon Olimpia's receipt of a minimum of 410,000,000
euro of proceeds on or before February 28, 2005 from the capital raising by
Olimpia described in Item 4 of Pirelli's Amendment No. 32 to its Statement on
Schedule 13D (the "Olimpia Capital Raising"). If this amount of proceeds is
received from the Olimpia Capital Raising on or before February 28, 2005, then
settlement of the transactions contemplated by the Mediobanca Forward Sale
Agreement will occur on a date (which is to be determined by Olimpia) prior to
May 31, 2005. However, the Mediobanca Forward Sale Agreement will terminate if
the proceeds received from the Olimpia Capital Raising on or before February 28,
2005 do not equal or exceed 410,000,000 euro unless Olimpia elects to (i)
proceed with the purchase of Telecom Italia Shares contemplated thereby or (ii)
arrange for a third party to purchase the Telecom Italia Shares on the terms set
forth above. If the Mediobanca Forward Sale Agreement is terminated for the
reason described in the previous sentence, Olimpia will be required to pay to
Mediobanca a termination fee. A copy of an English translation of the Mediobanca
Forward Sale Agreement is filed as an Exhibit to Amendment No. 33







to Pirelli's Schedule 13D, dated February 14, 2005, filed as Exhibit 50 to this
Schedule 13D and is incorporated by reference herein.

         Also on January 23, 2005, Olimpia announced that it had entered into a
forward sale agreement (the "JPMorgan Forward Sale Agreement"), dated as of
December 8, 2004, with JPMorgan Chase Bank NA ("JPMorgan") pursuant to which
Olimpia agrees to purchase from JPMorgan Chase Bank 424,130,480 convertible
bonds issued by Telecom Italia (the "Forward Sale Agreement Bonds") for an
aggregate purchase price equal to the sum of (x) 625,000,000 euro (the "Bonds
Purchase Price") and (y) an amount equal to the total interest accrued on the
Forward Sale Agreement Bonds (as reported on page BXT of the Bloomberg reporting
system) during the period from January 1, 2005 until the settlement date of the
transactions contemplated by the JPMorgan Forward Sale Agreement (the "Accrued
Interest Amount"). The Forward Sale Agreement Bonds are freely convertible into
an aggregate of 200,000,000 Telecom Italia Shares. Settlement of the
transactions contemplated by the JPMorgan Forward Sale Agreement is conditional
upon Olimpia's receipt of a minimum of 630,000,000 euro of proceeds on or before
February 28, 2005 from the Olimpia Capital Raising, and will take place within
five days of such occurrence. If the proceeds received from the Olimpia Capital
Raising on or before February 28, 2005 do not equal or exceed 630,000,000 euro,
then Olimpia will not be required to proceed with the purchase of the Forward
Sale Agreement Bonds. However, if Olimpia elects not to proceed with the
transaction, then it will be required to arrange for a third party to purchase
the Forward Sale Agreement Bonds with a settlement date of no later than March
15, 2005, and otherwise on the terms set forth above. If Olimpia is unable to
arrange for a third party to purchase the Forward Sale Agreement Bonds on such
terms, then Olimpia will be required to pay to JPMorgan a termination fee. A
copy of an English translation of the JPMorgan Forward Sale Agreement is filed
as an Exhibit to Amendment No. 33 to Pirelli's Schedule 13D, dated February 14,
2005, filed as Exhibit 51 to this Schedule 13D and is incorporated by reference
herein.

         A copy of a press release issued by Olimpia on January 23, 2005
concerning the Mediobanca Forward Sale Agreement and the JPMorgan Forward Sale
Agreement is filed as an Exhibit to Amendment No. 33 to Pirelli's Schedule 13D,
dated February 14, 2005, filed as Exhibit 52 to this Schedule 13D and is
incorporated by reference herein.

         On January 27, 2005, Olimpia entered into a forward sale agreement (the
"Caboto Forward Sale Agreement") with Banca Caboto S.p.A. ("Caboto") pursuant to
which Olimpia agrees to purchase from Caboto certain Telecom Italia Shares for
an aggregate purchase price of 400,000,000 euro, subject to the conditions
described below in this paragraph. The purchase price per Telecom Italia Share
will be determined by reference to the price paid by Caboto to acquire such
Telecom Italia Shares during the term of the Caboto Forward Sale Agreement
(subject to minor adjustments to reflect transaction costs that may be incurred
by Caboto), but will not in any event exceed 3.50 euro. The number of Telecom
Italia Shares to be acquired by Olimpia pursuant to the Caboto Forward Sale
Agreement will be determined by dividing 400,000,000 euro by the price per
Telecom Italia Share determined in accordance with the previous sentence. If the
weighted average market price of Telecom Italia Shares exceeds 3.50 euros for
any seven consecutive trading days during the term of the Caboto Forward Sale
Agreement, then either party may convene a meeting with the other party for the
purpose of renegotiating the terms of the purchase and sale of the Telecom
Italia Shares. If the parties are unable to reach an agreement within five
business days following the date of such meeting, then Caboto may elect to
terminate the Caboto Forward Sale Agreement. In






addition, settlement of the transactions contemplated by the Caboto Forward Sale
Agreement is conditional upon Olimpia's receipt of a minimum of 400,000,000 euro
of proceeds from the Olimpia Capital Raising on or before February 28, 2005. If
the proceeds received from the Olimpia Capital Raising on or before February 28,
2005 equal or exceed 400,000,000 euro, then settlement of the transactions
contemplated by the Caboto Forward Sale Agreement will occur on a date (which is
to be determined by Olimpia) prior to May 31, 2005. However, the Caboto Forward
Sale Agreement will terminate if the proceeds received from the Olimpia Capital
Raising on or before February 28, 2005 do not equal or exceed 400,000,000 euro
unless Olimpia elects to (i) proceed with the purchase of the Telecom Italia
Shares contemplated thereby or (ii) arrange for a third party to purchase the
Telecom Italia Shares on the terms set forth above. If the Caboto Forward Sale
Agreement is terminated for the reason described in the previous sentence, then
Olimpia will be required to pay to Caboto a termination fee. A copy of an
English translation of the Caboto Forward Sale Agreement is filed as an Exhibit
to Amendment No. 33 to Pirelli's Schedule 13D, dated February 14, 2005, filed as
Exhibit 53 to this Schedule 13D and is incorporated by reference herein.

         Reference is made to the Hopa Agreement (as that term is defined in

Intesa, Pirelli, Edizione Finance (as defined in Amendment No. 10 to the
Statement on Schedule 13D), Hopa, and UniCredito entered into an agreement that
amends the Hopa Agreement in certain respects (the "Hopa Agreement Amendment"),

provided that such acquisitions do not cause the aggregate number of Telecom
Italia Shares held by Olimpia and its shareholders to exceed 30% of the total
number of Telecom Italia Shares outstanding. Specifically (and subject to the
limitation described in the previous sentence), the Hopa Agreement Amendment
permits (i) Pirelli to acquire up to 300,000,000 Telecom Italia Shares, and (ii)
each of Intesa, Edizione Finance, Hopa, and UniCredito to acquire up to
100,000,000 Telecom Italia Shares. A copy of a press release issued by each of
Intesa, Pirelli, Edizione Finance, Hopa, and UniCredito regarding the Hopa
Agreement Amendment is filed as an Exhibit to Amendment No. 33 to Pirelli's
Schedule 13D, dated February 14, 2005, filed as Exhibit 54 to this Schedule 13D

the Hopa Agreement Amendment is filed as an Exhibit to Amendment No. 33 to
Pirelli's Schedule 13D, dated February 14, 2005, filed as Exhibit 55 to this

dated February 14, 2005, filed as Exhibit 56 to this Schedule 13D and is
incorporated by reference herein. The Pledge Shares secure certain obligations
of Olimpia arising under a revolving credit facility agreement, dated as of
January 12, 2005, by and among Olimpia and each of the Pledgees. A copy of the
revolving credit facility agreement is filed as an Exhibit to Amendment No. 33
