               TELEFONOS DE MEXICO, S.A. DE C.V. AND SUBSIDIARIES
         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
       (Amounts in thousands of Constant Pesos as of September 30, 2003)

1. Significant Accounting Policies

a)        Basis of presentation:

          The accompanying unaudited condensed consolidated financial statements
are presented on the same basis of accounting as described in the audited
financial statements of Telefonos de Mexico, S.A. de C.V. and its subsidiaries
(collectively "the Company" or "TELMEX") as of December 31, 2002 and for each of
the three years in the period ended December 31, 2002 (the audited financial
statements), and have been prepared in accordance with generally accepted
accounting principles for interim financial information. Accordingly, they do
not include all the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of
management, all adjustments (consisting of normal recurring accruals) considered
necessary for a fair presentation of financial information have been included.

          The condensed consolidated balance sheet as of December 31, 2002 has
been derived from the financial statements at that date, but does not include
all of the information and footnotes required by generally accepted accounting
principles for complete financial statements.

b)       Recognition of the effects of inflation on financial information:

          The unaudited condensed consolidated financial statements were
prepared in accordance with Bulletin B-10 ("Accounting Recognition of the
Effects of Inflation on Financial Information") as described in the audited
annual consolidated financial statements; consequently, all financial statements
presented herewith were restated to constant pesos as of September 30, 2003. The
September 30, 2003 restatement factor applied to the financial statements at
December 31, 2002 and September 30, 2002 was 1.0230 and 1.0393, which represent
the rate of inflation from December 31, 2002 and September 30, 2002 up to
September 30, 2003, respectively, based on the Mexican National Consumer Price
Index (NCPI) published by Banco de Mexico (the Central Bank).

          The condensed consolidated balance sheet as of December 31, 2002 has
been derived from the audited financial statements at that date, which were
initially presented in constant pesos as of December 31, 2002. The December 31,
2002 financial statements included in this report are presented in constant
pesos as of September 30, 2003, because they are included with the unaudited
condensed consolidated financial statements as of September 30, 2003 expressed
in constant pesos as of September 30, 2003.

c)       Convenience translation:

          United States dollar amounts as of September 30, 2003 shown in the
unaudited condensed consolidated financial statements have been included solely
for the convenience of the reader and are translated from Mexican pesos with
purchasing power as of September 30, 2003, as a matter of mathematical

2. Cash and Short-term Investments

          The Company has invested in equity securities and several series of
bonds issued by MCI, Inc. (formerly known as WorldCom, Inc.), a U.S.-based
telecommunications company that is in Chapter 11 proceedings under the U.S.
bankruptcy code. As of September 30, 2003, TELMEX held approximately U.S.$1,759
million in face amount of the bonds, with a market value of approximately
U.S.$580 million at such date. On October 31, 2003, the bankruptcy court
approved a plan of reorganization for MCI. Under the plan, the Company expects
to receive common stock of MCI in exchange for the bonds. The amount of stock to
be received will depend on a number of factors, including the amount of other
valid claims and the elections made by other creditors. Based on TELMEX's
current holdings, and assuming that the plan of reorganization does not change,
the Company estimates that if the reorganization were implemented today, it
would receive an amount of common stock equal to approximately 7% of the total
common stock of MCI.

          At September 30, 2003, this caption includes equity securities and
corporate bonds for trading in the amount of P.6,907,033 (P.1,621,518 at
December 31, 2002), of which approximately U.S.$580 million and U.S.$1 million
are MCI, Inc. bonds and shares, respectively (U.S.$117 million and U.S.$5
million at December 31, 2002). The Company included in the comprehensive
financing cost for the nine-month period ended September 30, 2003, an unrealized
gain of P. 1,882,106 for the increase in the market value of equity securities
(including P.1,696,565 on MCI bonds). In the nine-month period ended September
30, 2002, the caption included an unrealized loss of P.1,246,912 (including
P.669,965 on MCI shares). The net realized loss on the sale of equity securities
in 2003 was P. 13,270 (net realized loss of P.76,072 in 2002).

          The above-mentioned rates are subject to changes in international and
local rates and do not include the effect of the Company's agreement with
certain lenders to gross-up Mexican taxes withheld. The Company's weighted
average cost of borrowed funds at September 30, 2003 (including interest, fees
and gross-up for Mexican taxes withheld) was approximately 5.81% (5.77% at
December 31, 2002).

          Short-term debt as of September 30, 2003 amounted to P.3,799,061
(P.812,961 at December 31, 2002), comprised of P.1,777,529 of commercial paper
(P.171,707 at December 31, 2002) and P.2,021,532 of banks (P.641,254 at December
31, 2002), with a weighted average interest rate of 3.2% (3.5% at December 31,
2002).

     (1) On June 11, 1999, the Company issued U.S.$1,000 million of convertible
     senior debentures. The debentures are convertible to common stock at the
     option of the holders, at any time prior to their maturity into American
     Depositary Shares (ADSs), each representing 20 TELMEX "L" shares. The
     conversion price is U.S.$29.5762 per ADS, equal to a conversion ratio of
     33.8110 "L" share ADSs per U.S.$1,000 principal amount of the convertible
     debentures, subject to adjustment under certain circumstances.

          Should any person or group (other than the present controlling
     stockholders) acquire 50% or more of the issuer's voting shares, the
     holders of the convertible debentures may ask TELMEX to repurchase the
     convertible debentures, for 100% of the principal amount plus unpaid
     accrued interest through the repurchase date. The maturity date of the
     convertible debentures is June 15, 2004. The debentures bear 4.25% annual
     interest, payable semiannually.

          During the third quarter of 2003, TELMEX repurchased a total of
     U.S.$190 million (nominal value) of convertible debentures in the open
     market and in privately negotiated transactions. The Company charged
     U.S.$20.5 million to the comprehensive financing cost, corresponding to the
     difference between purchase price and nominal value of debentures.

          On October 9, 2003, TELMEX commenced a cash tender offer to purchase
     up to U.S.$500 million of its outstanding convertible senior debentures.
     The offer was made upon the terms and subject to the conditions set forth
     in the Offer to Purchase. The offer expired on November 6, 2003 and the
     Company purchased U.S.$1.2 million (nominal value) of convertible
     debentures. The cash price for each U.S.$1,000 principal amount of the
     debentures was U.S.$1,117.50 plus accrued and unpaid interest to (but
     excluding) the date of purchase. All debentures purchased pursuant to the
     offer, together with all the debentures previously repurchased by TELMEX
     will be cancelled.

     2003 is as follows:

          Some of the above-mentioned loans are subject to certain restrictive
covenants with respect to maintaining certain financial ratios and selling off a
substantial portion of group assets, among others. At September 30, 2003, the
Company has met all of these requirements.

          From May through September 2003, the Company prepaid part of its
outstanding debt with several financial institutions for U.S.$727 million,
approximately.

Hedges

          As part of its currency hedging strategy, the Company uses derivatives
to minimize the impact of exchange rate fluctuations on U.S. dollar denominated
transactions. During 2002, the Company entered into short-term exchange hedges,
which, at September 30, 2003, cover liabilities of U.S.$880 million (U.S.$418
million at December 31, 2002). In the nine-month period ended September 30,
2003, the Company recognized a credit to results of operations under these
hedges of P. 549,870 (credit of P. 1,611,324 in 2002) corresponding to the
fluctuation of the exchange rate.

          To hedge its exposure to financial risks, the Company entered into
interest-rate swaps for the exchange of cash flows for the amount determined by
applying agreed interest rates to the base amount. Under these contracts, the
Company agreed to receive the "TIIE" interbank rate and to pay a fixed rate.

          These swaps were recorded in results of operations of the year at the
related market interest rates. At September 30, 2003 the Company had
peso-denominated interest-rate swaps for a total base amount of P. 12,390
million and U.S.-denominated interest-rate swaps for a total base amount of
U.S.$ 1,200 million (P.12,941 of peso-denominated interest-rate swaps at
December 31, 2002). In the nine-month period ended September 30, 2003 the
Company recognized a charge under these contracts of P.292,711 to the
comprehensive financing cost (P.216,124 in 2002). Additionally, in 2003 the
Company replaced peso-denominated interest-rate swaps and recognized a charge of
P.946,779.

7.         Foreign Currency Position

          At September 30, 2003, TELMEX and its Mexican subsidiaries have a net
foreign currency short position of U.S.$4,586 million (net foreign currency
short position of U.S.$5,565 million at December 31, 2002). The prevailing

10.        Stockholders' Equity

a)        At September 30, 2003, capital stock is represented by 12,288 million
shares issued and outstanding with no par value, representing the Company's
fixed capital (12,777 million at December 31, 2002).

b)       Earnings per share are obtained by dividing net income for the year by
the average weighted number of shares issued and outstanding during the period.
To determine the average weighted number of shares issued and outstanding in the
nine-month periods ended September 2003 and 2002, the shares held by the Company
have been excluded from the computation.

          The diluted earnings per share in the nine-month periods ended
September 30, 2003 and 2002, were determined considering the effect of the
shares that may be delivered (potentially dilutive shares) as a result of the
convertible senior debentures described in Note 6. The computation was made by
adjusting net income for the period, by the applicable comprehensive financing
cost (including interest expense, exchange gain difference and monetary gain),
net of income tax and employee profit sharing, attributable to the convertible
debentures. The adjusted income was divided by the average weighted number of
shares issued and outstanding, taking into account the number of convertible
shares.

          An analysis is as follows:


                                                                      Nine months ended

13.        Differences between Mexican and U.S. GAAP

          The Company's unaudited condensed consolidated financial statements
are prepared in accordance with Mexican GAAP, which differ in certain
significant respects from generally accepted accounting principles in the United
States ("U.S. GAAP").

          The following reconciliation to U.S. GAAP does not include the
reversal of the adjustments to the financial statements for the effects of
inflation required under Mexican GAAP (Bulletin B-10), because the application
of Bulletin B-10 represents a comprehensive measure of the effects of price
level changes in the Mexican economy and, as such, is considered a more
meaningful presentation than historical cost-based financial reporting for both
Mexican and U.S. accounting purposes. The principal differences between Mexican
GAAP and U.S. GAAP, as they relate to the Company, are described in Note 18 to
the audited financial statements.


          Cash Flow Information:

          Under Mexican GAAP, the Company presents consolidated statements of
changes in financial position, as described in Note 1 to the audited financial
statements. The changes in the consolidated financial statement balances
included in this statement constitute resources provided by and used in
operating, financing and investing activities stated in constant pesos
(including monetary and foreign exchange gains and losses). For Mexican GAAP
purposes, trading securities have been presented in cash and short term
investments, therefore the changes in these securities are presented as part of
the net increase (decrease) in cash and short term investments; under U.S. GAAP
the cash flows from these type of securities should be disclosed as cash
provided by (used in) operating activities.

          Statement of Financial Accounting Standards No.95 ("SFAS No. 95"),
"Statement of Cash Flows," does not provide guidance with respect to inflation
adjusted financial statements. In accordance with Mexican GAAP, the changes in
current and long-term debt due to restatement in constant pesos, including the
effect of exchange differences, is presented in the statement of changes in
financial position in the financing activities section. The Company has adopted
the guidance issued by the AICPA SEC Regulations Committee's International
Practices Task Force in its meeting held on November 24, 1998, encouraging
foreign registrants that file price level adjusted financial statements to
provide cash flow statements that show separately the effects of inflation on
cash flows. If the changes in trading securities, the monetary gain and the
exchange gain or loss related to the debt, were treated as components of
operating activities, summarized unaudited condensed consolidated interim
statements of cash flows derived from information prepared in accordance with
U.S. GAAP would be as follows:


                                                                                   Nine months ended
