• The October 3, 2006, "Acuerdo de Convergencia" (Convergence Agreement), which was issued by the Federal Government through the Secretaría de Comunicaciones y Transportes (Communications and Transportation Ministry), established the basis for the convergence of networks more than 21 months ago.
• Nevertheless, even though TELMEX has met the requirements in a timely manner, to date there has not been a favorable resolution form the authority that would allow the company to participate in the various telecommunications services that will be offered in a competitive market in which consumers benefit from faster and better attention which is affecting the company and the development of telecommunications in the country.
• It is important to mention that cable TV operators have been offering voice, data and video services to their customers for more than 2 years and with lower investments.

• At TELMEX, we have carried out investments to maintain state-of-the-art technology, and we constantly are working on increasing the company's productivity and reducing our operating costs. Additionally, we are driving the digital culture through broadband services, the sale of computers, multi-service packages and providing connectivity to thousands of communities that cover more than 90% of the population.
• The sale of computers in installments of up to 48 months increases penetration of computers in Mexican homes, since only 22.1% of them have a computer. That proportion is significantly below the average of nearly 62% for member countries of the OECD.
• TELMEX continues to experience substantially decreased voice service revenues due to ongoing price reduction and strong competition. TELMEX's market share is 19.0% in the voice market overall, which includes both local and cellular operators, and 48.1% in the market segment consisting only of operators of fixed lines.

Telecommunications market in Mexico*-June 2008

*Estimated

• During the second quarter, there was a gain of 488 thousand broadband Infinitum accounts (ADSL), an increase of 59.8% compared with the same period of 2007. At June 30, TELMEX served 4.1 million Internet services of which 93% are broadband Infinitum.

• In the second quarter, total revenues were 30.9 billion pesos, 6.3% lower than the same period of the previous year. These results reflected increases of 19.6% in Internet access revenues and 4.1% in corporate networks revenues and decreases of 10.4% and 9.0% in local and long distance revenues, respectively.

• EBITDA (1) totaled 14.4 billion pesos, 7.5% lower than the second quarter of the previous year. Operating income totaled 9.9 billion pesos, 9.8% lower than last year's second quarter.

• Majority income from continuing operations in the quarter totaled 6.2 billion pesos, 13.0% lower than the same period of last year. In the second quarter, earnings per share were 33 Mexican cents, a decrease of 8.3%, and earnings per ADR (2) were 64 US cents, a decrease of 1.5% compared with the second quarter of 2007.

• At June 30, net debt (3) increased the equivalent of 830 million dollars to a total of 7.925 billion dollars compared with June 30, 2007.

• Capital expenditures (Capex) were equivalent to 338 million dollars for the first half. In the quarter, the company repurchased 192 million 423 thousand of its own shares.

(1) EBITDA: defined as operating income plus depreciation and amortization. Go to www.telmex.com in the Investor Relations section where you will find the reconciliation of EBITDA to operating income.

(2) One ADR represents 20 shares.

(3) Net debt is defined as total debt less cash and cash equivalents and marketable securities.

At the end of the second quarter, there were 17.7 million lines in service, a decrease of 3.0% compared with the same period of 2007, due to disconnections caused by the increase in competition from both fixed and cellular lines and to growth in broadband Infinitum services, which in some cases represent substitutions for conventional lines.

Of our lines in service, approximately 10.4 million are in areas that interest competitors and where they also have presence. However, 7.3 million lines are in areas that hold no interest to competitors. For the six months these lines generated revenues of approximately 9.937 billion pesos and an operating loss of 1.226 billion pesos.

During the second quarter, local traffic decreased 10.3% compared with the same period in 2007, with a total of 5.644 billion local calls. Local traffic volume was affected by competition from local and cellular telephony and by managed networks, a trend that strengthens the data business although it adversely affects local traffic.

Domestic long distance (DLD) traffic increased 11.3% compared with last year's second quarter, totaling 5.119 billion minutes, due to more packages that include DLD minutes and higher traffic from cellular operators, offset by the decrease in termination traffic with other long distance operators.

In the quarter, outgoing international long distance (ILD) traffic increased 13.8% compared with last year's second quarter, totaling 539 million minutes due to more traffic from cellular operators. Incoming international long distance traffic decreased 16.3% compared with the same period of the previous year, totaling 1.649 billion minutes. The incoming-outgoing ratio was 3.1x.

In the second quarter, interconnection traffic increased 1.0% compared with the second quarter of the previous year, totaling 11.482 billion minutes. Calling party pays traffic decreased 10.5% as a result of the decrease in local and international calling party pays traffic and to the increase of cellular services. Interconnection traffic with local, long distance and cellular telephony operators increased 5.0%.

At June 30, 2008, TELMEX had 4.1 million Internet access services, of which 3.8 million are broadband Infinitum. In the second quarter, we obtained a record quarterly gain of 488 thousand Infinitum accounts, 92.7% higher than the number of new accounts opened in last year's second quarter.

Growth of broadband Infinitum services has been supported by the sale of multi-service packages that offer access to broadband service along with various voice services at competitive prices. Multi-service packages increased 71.8% compared with last year's second quarter. The sale of computers also contributed to the increase in revenues of Tiendas TELMEX (TELMEX Stores) and of our telmex.com portal.

In the corporate market, billed line equivalents for data transmission increased 36.4% compared with the second quarter of 2007, bringing the total to 3.4 million line equivalents of 64 Kbps.

Revenues: In the second quarter, revenues totaled 30.9 billion pesos, a decrease of 6.3% compared with the same period of the previous year. This result was due to the increases of 19.6% in Internet access revenues, 4.1% in corporate networks revenues and 47.4% in other revenues, which includes revenues from Tiendas TELMEX (TELMEX stores) and from the telmex.com portal, as well as for decreases of 10.4% and 9.0% in local and long distance services, respectively, and for the 19.5% decrease in interconnection revenues resulting from the 10.5% decrease in traffic volume and the 9.9% decline in the calling party pays rate.

Local: Local revenues totaled 12.327 billion pesos in the second quarter, a decrease of 10.4% compared with the second quarter of 2007 due to the 8.5% reduction in real terms of revenue per local billed call and to the decrease in local traffic due to competition from both cellular telephony and other fixed telephony operators.

DLD: DLD revenues totaled 4.175 billion pesos in the second quarter, 5.2% lower than the second quarter of 2007. The 11.3% increase in traffic was not enough to offset the 11.3% decrease in the average revenue per minute.

ILD: In the second quarter, ILD revenues totaled 2.103 billion pesos, a decrease of 15.6% compared with the second quarter of the previous year. Revenues from outgoing traffic declined 11.8% to 1.388 billion pesos compared with the second quarter of 2007 due to the 15.5% decrease in average revenue per minute, partially offset by the 13.8% increase in outgoing ILD traffic. Incoming international long distance revenues totaled 716 million pesos, a decrease of 22.1% compared with the second quarter of 2007, reflecting the 16.3% decrease in incoming traffic.

Interconnection: In the second quarter, interconnection revenues decreased 19.5% to 4.774 billion pesos compared with the same period of 2007, mainly due to the 10.5% decline in calling party pays traffic and the decrease of 9.9% in the calling party pays rate.

Corporate networks: In the second quarter, revenues from services related to data transmission through private and managed networks totaled 2.872 billion pesos, 4.1% higher than the same period of the previous year. The increase was due to the higher number of services and the sale of value-added services, which offset the reduction in unit prices of these services.

Internet: Revenues from Internet access in the second quarter totaled 3.190 billion pesos, 19.6% higher than last year's second quarter due to the increase of 39.4% in Internet services, partially offset by lower average unit revenue for broadband Infinitum services.

Costs and expenses: In the second quarter, total costs and expenses were 21.013 billion pesos, a decrease of 4.6% compared with the second quarter of 2007. This decrease was mainly due to initiatives carried out to optimize resource use, to the 12.4% decrease in the amount paid to cellular operators for calling party pays services, partially offset by higher charges related to the sale of computers and equipment for customers and to the increase in the provision for uncollectables.

Cost of sales and services: In the second quarter, cost of sales and services decreased 2.2% compared with the same period of 2007, totaling 8.055 billion pesos, due to higher computer and telecommunications equipment costs related to higher sales, offset by initiatives carried out to optimize resource use.

Commercial, administrative and general: In the quarter, commercial, administrative and general expenses totaled 4.973 billion pesos, 2.5% higher than last year's second quarter due to an increase in the provision for uncollectables related to services rendered to another telecommunications operator.

Interconnection: In the second quarter, interconnection costs totaled 3.473 billion pesos, a decrease of 19.9% compared with the same period of 2007 as a result of the 12.4% decrease in the amount paid to cellular telephony operators for calling party pays service and the decrease of 10.5% in calling party pays traffic.

Depreciation and amortization: In the quarter, depreciation and amortization decreased 1.8% to 4.512 billion pesos due to a lower lever of investment in recent years.

EBITDA (1) and operating income: EBITDA (1) totaled 14.424 billion pesos in the second quarter, a decrease of 7.5% compared with the same period of last year. The EBITDA margin was 46.6%. Operating income totaled 9.912 billion pesos in the second quarter and the operating margin was 32.1%.

Comprehensive financing cost: Comprehensive financing cost produced a charge of 598 million pesos in the quarter. This resulted from: i) a net interest charge of 578 million pesos, 864 million pesos less than the charge registered in the same period of 2007, due to recognition of the market value of interest rate swaps and the decrease in the level of indebtedness, ii) a net exchange loss of 20 million pesos from the second-quarter exchange rate appreciation of 0.4121 pesos per dollar, offset by 6.977 billion dollars in dollar-peso hedges (weighted average exchange rate: 10.7671 pesos per dollar) and iii) recognition of a decline in the monetary position of 270 million pesos in 2007, an effect that is absent in 2008 under current accounting rules.

Majority income from continuing operations: Majority net income from continuing operations in the second quarter totaled 6.187 billion pesos, 13.0% lower than the same period of the previous year. Earnings per share were 33 Mexican cents, a year-over-year decrease of 8.3%, and earnings per ADR were 64 US cents, a decrease of 1.5% compared with the same period of 2007.

Investments: In the first half, capital expenditures (capex) were the equivalent of 338 million dollars, of which 74.9% was used for growth projects in the voice, data and transport infrastructure and 24.9% for operational support projects and operating needs.

Debt: Total debt at June 30 was the equivalent of 8.872 billion dollars, of which 86.8% is long-term. Of the total debt, 76.4% is in foreign currency and 46.0% has fixed rates. The foreign currency proportion converts to 73.2% if 23.752 billion pesos and 100 million dollars of interest rate swaps at average interest rate of 8.145% and 4.47%, respectively, are included. Total net debt (3) increased during the last twelve months the equivalent of 830 million dollars, totaling 7.925 billion dollars.

Repurchase of shares: During the second quarter, the company repurchased 192 million 423 thousand of its own shares.

(1) EBITDA: defined as operating income plus depreciation and amortization. Go to www.telmex.com in the Investor Relations section where you will find the reconciliation of EBITDA to operating income.
