Commission (the "Commission"), as subsequently amended, by the Reporting Persons
(as defined in the Schedule 13D), with respect to the L Shares and A Shares of

otherwise defined in this Eighteenth Amendment have the meanings ascribed to

Shares purchased by CGT since the filing by the Reporting Persons of Amendment
No. 17 to the Schedule 13D on February 25, 2005, was U.S.$31,483,700. The funds

(1)  Based upon 248,198,709 A Shares outstanding as of May 5, 2005, as reported
     by the Mexican Stock Exchange. Includes A Shares held in the form of A
     Share ADSs. Except as otherwise indicated, all A Shares are held in the
     form of A Shares.
(2)  Based upon 7,274,301,290 L Shares outstanding as of May 5, 2005, as
     reported by the Mexican Stock Exchange. The total number of L Shares
     outstanding also includes L Shares held in the form of L Share ADSs. In
     addition, other than in the case of GFI, the Telmex Trust, the Telnor
     Trust, Fundacion Telmex and Asociacion Carso, L Share totals and
     percentages assume that all of the A Shares held by the Reporting Persons
     and 1,746,233,821 AA Shares held by CGT, which may be deemed to be
     beneficially owned by the Slim Family, have been converted into L Shares.
     In accordance with the restrictions set forth in Item 4 of the Schedule 13D
     filed by the Reporting Persons on February 20, 2004, the maximum number of
     AA Shares that could, as of the date hereof, be converted to L Shares is
     1,746,233,821. Except as otherwise indicated, all L Shares are held in the
     form of L Shares.
(3)  Includes 40,000 A Shares and 100,000 L Shares (assuming conversion of the
     40,000 A Shares) owned directly by Carlos Slim Helu, as well as A Shares
     and L Shares beneficially owned through GFI and CGT by trusts for the
     benefit of the Slim Family (the "Family Shares").
(4)  Includes 8,132 L Shares owned directly by Carlos Slim Domit, as well as the
     Family Shares.
(5)  Includes 8,132 L Shares owned directly by Marco Antonio Slim Domit, as well
     as the Family Shares.
(6)  Includes 335,324 L Shares owned directly by Patrick Slim Domit, as well as
     the Family Shares.
(7)  Includes 8,134 L Shares owned directly by Maria Soumaya Slim Domit, as well
     as the Family Shares.
(8)  Includes 408,134 L Shares owned directly by Vanessa Paola Slim Domit and
     her spouse, as well as the Family Shares.
(9)  Includes 570,134 L Shares owned directly by Johanna Monique Slim Domit and
     her spouse, as well as the Family Shares.

         (b) Because the Slim Family may be deemed to control, directly or
indirectly, each of CGT, GFI and the Issuer, the Slim Family may be deemed to
share the power to vote or dispose of, or to direct the voting or disposition
of, any A Shares or L Shares controlled by such persons (including those
beneficially owned by the Telmex Trust, the Telnor Trust, Fundacion Telmex and
Asociacion Carso). Except as otherwise disclosed herein, none of the Reporting
Persons shares voting or disposition power with respect to any of the A Shares
or L Shares owned by the Reporting Persons.

        (c) All transactions in A Shares and L Shares effected by the Reporting
Persons in the 60 days preceding the date of the event requiring the filing of
this statement are listed in Schedule II hereto.

        (d) All A Shares and L Shares owned by trusts for the benefit of the
Slim Family may be deemed to be beneficially owned by each member of the Slim
Family that is a beneficiary of such trusts. Thus, beneficial ownership of A
Shares and L Shares may be deemed to be shared by each member of the Slim
Family. Because the Slim Family may be deemed to control, directly or
indirectly, each of CGT, GFI and the Issuer, the Slim Family may be deemed to
have the right to receive or the power to direct the receipt of dividends from,
or the proceeds of the sale of, any A Shares or L Shares controlled by such
persons (including the Telmex Trust, the Telnor Trust, Fundacion Telmex and
Asociacion Carso). Except as disclosed herein, no person other than the
Reporting Persons has or will have any right to receive or the power to direct
the receipt of dividends from, or the proceeds of the sale of, A Shares or L
Shares owned by the Reporting Persons.

        (e) Not applicable.
