                  This Amendment No. 50 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, Sintonia S.p.A. (which, it publicly
announced on March 9, 2007, has replaced Edizione Holding in various
shareholders agreements relating to Olimpia) and Sintonia S.A. (which, according
to Sintonia S.p.A.'s public announcement, is the new name of Edizione Finance)
are members of a group with respect to the Telecom Italia Shares. (By virtue of
the 2006 Shareholders Agreement described in Amendment No. 45 to the Statement
on Schedule 13D, Assicurazioni Generali S.p.A. and Mediobanca S.p.A. may also be
deemed to be members of that group.) 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 Sintonia S.p.A., its predecessor
Edizione Holding or Sintonia S.A. has been provided by the nominating person or
by such nominee director or officer.

ITEM 4.   PURPOSE OF TRANSACTION

                  On March 12, 2007, Pirelli & C. issued a press release about
its financial results for 2006, which, among other things, contained the
following statement: "With regard to the holding in Olimpia, the Board of
Directors [of Pirelli & C.] then gave a mandate to the Chairman to explore all
possible options, without excluding sale of the holding, in order to bring out
the best strategic value of the asset in the interest of all shareholders."
