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 3,655,818,238 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 3,655,818,238.

(10) Includes L Shares owned directly by CGT as well as L Shares beneficially owned through its wholly-owned subsidiaries. (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).
