           This Amendment No. 33 amends the Statement on Schedule 13D, dated
August 9, 2001, as amended (as previously amended, the "Statement on Schedule
13D"), filed by Pirelli S.p.A. (which, as reported in Amendment No. 21 to the
Statement on Schedule 13D, subsequently merged with and into Pirelli & C.
S.p.A., a company incorporated under the laws of the Republic of Italy), and,
commencing with Amendment No. 1 thereto, Olimpia S.p.A., a company incorporated
under the laws of the Republic of Italy, 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.

           Pirelli & C., Olimpia, Edizione Holding and Edizione Finance, Hopa,
UCI and BCI are members of a group with respect to the Telecom Italia Shares.
This Amendment constitutes a separate filing on Schedule 13D by Pirelli & C. and
Olimpia in accordance with Rule 13d-1(k)(2) under the Securities Exchange Act of
1934. Pirelli & C. and Olimpia are responsible solely for the information
contained in their separate filing, except that information contained in the
Statement on Schedule 13D concerning any director or officer of Olimpia
nominated by Edizione Holding, Hopa, UCI or BCI has been provided by the
nominating person or by such nominee director or officer.

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 Amendment No. 32 to the 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


                               Page 4 of 9 pages

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 Exhibit 68.

           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 Exhibit 69.

           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 Exhibit 70.

           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


                               Page 5 of 9 pages

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 Exhibit 71.

           Reference is made to Item 4 of Amendment No. 32 to the Statement on

to 1,078,000,000 euro. The capital increase is to be effected through the
issuance to existing shareholders of Pirelli & C. of up to 1,539,291,916
ordinary shares of Pirelli & C. As reported in Item 4 of Amendment No. 32 to the

           Reference is made to the Hopa Agreement (as that term is defined in
Amendment No. 17 to the Statement on Schedule 13D). On January 27, 2005, each of

amends the Hopa Agreement in certain respects (the "Hopa Agreement Amendment"),
including by allowing those parties to acquire certain Telecom Italia Shares,


                               Page 6 of 9 pages

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 & C. to acquire up to 300,000,000 Telecom Italia Shares, and
(ii) each of Edizione Finance, Hopa, BCI and UCI to acquire up to 100,000,000
Telecom Italia Shares. A copy of a press release issued by each of Pirelli & C.,
Edizione Finance, Hopa, BCI and UCI regarding the Hopa Agreement Amendment is
filed as Exhibit 72. A copy of an English translation of the Hopa Agreement
Amendment is filed as Exhibit 73.

           On January 20, 2005, Olimpia pledged 920,892,723 Telecom Italia
Shares (the "Pledge Shares") in favor of Banca di Roma S.p.A., BCI, Bipop Carire
S.p.A., Banca di Sicilia S.p.A., Irfis Mediocredito della Sicilia S.p.A., MCC
S.p.A., Unicredit Banca D'impresa S.p.A., Calyon S.A., Morgan Stanley Bank
International Limited, Morgan Stanley Bank European Funding, Inc. and Societe
Generale (collectively, the "Pledgees") pursuant to a pledge agreement, dated as
of January 20, 2005. An English translation of the pledge agreement is filed as
Exhibit 74. 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 Exhibit 75. Under the revolving credit facility
agreement, the Pledgees agree to lend to Olimpia an aggregate amount of up to
2,400,000,000 euro on the terms and conditions set forth therein. Prior to
January 20, 2005, the Pledge Shares were pledged in favor of BCI, Unicredit
Banca Mobiliare S.p.A., Banca di Roma S.p.A., Banca CRT S.p.A. and Rolo Banca
1473 S.p.A. (collectively, the "Prior Pledgees") pursuant to the pledge
