• In Mexico, telecommunications prices will continue to decrease substantially as a result of technological advances, competition and the convergence of networks. The country should strive to make telecommunications products a universal service and encourage the evolution from partial voice and video solutions to integrated convergent services. This process supports the development of communities and generates a multiplying effect in the country's economy that benefits consumers and society.

• Given the declarations and often confusing information disseminated by competitors, it is important to clarify that for the past 18 years, TELMEX has participated in a sector that has been open to competition in every market where the company operates, except in the case of long distance services where competition began more than 11 years ago.

• It is important to note that all cable TV operators currently are able to offer voice and data services to their video customers. In order for complete convergence to exist in the country, it is important that all foreign and domestic telecommunications operators be allowed to participate in this market to benefit consumers in every market segment.

• TELMEX's fixed line market share is 80.9% with a total of 17.8 million lines, of which approximately 10.5 million lines are in areas that appeal to competitors and where they have presence. The remaining 7.3 million lines are in areas that hold no interest for competitors. In the first quarter, the lines without competition generated revenues of 5.072 billion pesos and an operating loss of 534 million pesos.

• Growth of broadband Infinitum services has been supported by computer sales, which has increased revenues of Tiendas TELMEX (TELMEX stores). The lack of computers significantly limits growth of broadband services in Mexico since 4 out of 5 homes do not have a computer. In homes with computers, approximately 80% have Internet access. TELMEX will continue to sell computers in installments with preferred terms in order to drive the digital culture in the country.

• In the first quarter, total revenues were 31.1 billion pesos, 5.5% lower than the same period of the previous year. These results reflected decreases of 9.4% and 8.6% in local and long distance revenues, respectively, and increases of 10.1% in corporate networks revenues and 8.4% in Internet access revenues.

• EBITDA (1) totaled 15.2 billion pesos, 7.7% lower than the first quarter of the previous year. Operating income totaled 10.6 billion pesos, 10.2% lower than last year's first quarter.

• Majority net income from continuing operations in the quarter totaled 5.6 billion pesos, 26.7% lower than the same period of last year. In the first quarter, earnings per share were 29 Mexican cents, a decrease of 23.7%, and earnings per ADR (2) were 55 US cents, a decrease of 17.9%, compared with the first quarter of 2007.

• At March 31, net debt (3) increased the equivalent of 752 million dollars to a total of 7.957 billion dollars compared with March 31, 2007.

• Capital expenditures (Capex) were equivalent to 108 million dollars for the quarter. Share repurchases totaled 4.693 billion pesos during the first quarter.

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

On March 12, 2008, the Board of Directors passed resolutions calling for series "L" Special and Annual Shareholders' Meetings to be held on April 25, 2008, in order to discuss, among other matters, the following proposals: to appoint the members of the Board of Directors pertaining to Series "L" shares and to declare a cash dividend of $0.40 Mexican pesos per outstanding share (excluding the cash dividend which Telmex Internacional, S.A.B. de C.V. may approve) in four equal payments of $0.10 Mexican pesos per outstanding share, resulting from the net tax profit account. Dividend payments are proposed to be made in México on June 19, 2008, September 18, 2008, December 18, 2008, and March 26, 2009.

Additionally, the Board of Directors of Telmex Internacional, S.A.B. de C.V. will propose to the Shareholders' Meeting a cash dividend of $0.15 Mexican pesos per outstanding share, resulting from the net tax profit account. The proposed dividend payment will be effective when Telmex Internacional, S.A.B. de C.V. shares have been distributed to shareholders as a result of the escisión, approved by Telmex's Extraordinary Shareholders' Meeting held on December 21, 2007, and such shares begin to trade on the several stock markets.

For information purposes, and notwithstanding that the escisión of Telmex Internacional S.A.B. de C.V. has been fully effective, it is noted that the sum of both proposed cash dividend payments would be equal to $0.55 Mexican pesos per TELMEX outstanding share, before the distribution of shares issued by Telmex Internacional S.A.B. de C.V. takes place.

At the end of the first quarter, there were 17.8 million lines in service, a level similar to that of December 2007. The activation of lines driven by new service packages offset the increase in the competition's activity in the most attractive segments of the market. The flat number of lines also reflected growth in broadband services that in some cases represent substitutions for conventional lines.

During the first quarter, local traffic decreased 7.3% compared with the same period in 2007, with a total of 5.820 billion local calls. Local traffic volume continues to be affected by competition from local and mobile telephony. Also affecting local traffic results is the migration of dial-up Internet services to Infinitum broadband services (ADSL).

Domestic long distance (DLD) traffic increased 5.2% compared with last year's first quarter, totaling 4.702 billion minutes, due to the increase of packages that include DLD minutes and to the increase in traffic from mobile operators, offset by the decrease in termination traffic with other long distance operators.

In the quarter, outgoing international long distance (ILD) traffic increased 11.2% compared with last year's first quarter, totaling 531 million minutes due to more traffic from mobile operators. Incoming international long distance traffic decreased 21.4% compared with the same period of the previous year, totaling 1.563 billion minutes. The incoming-outgoing ratio was 2.9x.

In the first quarter, interconnection traffic increased 4.9% compared with the first quarter of the previous year, totaling 11.364 billion minutes. Calling party pays traffic decreased 4.5% as a result of the decrease in international calling party pays traffic due to bypass from other operators. Interconnection traffic with local, long distance and mobile telephony operators increased 8.2%.

At March 31, 2008 TELMEX had 3.6 million Internet access services, of which 3.3 million are broadband Infinitum. In the quarter, there was a gain of 391 thousand Infinitum accounts, 28.6% higher than the gain in last year's first quarter. TELMEX's initiatives to grow Infinitum contribute to increased Internet access in Mexico, where 13% of homes now have access to broadband.

Growth of broadband Infinitum services has been supported by computer sales, which has increased revenues of Tiendas TELMEX (TELMEX stores). The lack of computers significantly limits growth of broadband services in Mexico since 4 out of 5 homes do not have a computer. In homes with computers, approximately 80% have Internet access. TELMEX will continue to sell computers in installments with preferred terms in order to drive the digital culture in the country.

Subscriptions to multiservice packages that offer broadband access service along with different voice services at competitive prices increased 18.9% compared with last year's first quarter. As part of this strategy, in February 2008 we launched the "Paquete Acerques," a package that costs 599 pesos per month, VAT included, for monthly rent, broadband Infinitum service, unlimited DLD calls, 200 local calls and digital services.

In the corporate market, billed line equivalents for data transmission increased 31.8% compared with the first quarter of 2007, bringing the total to 3.1 million line equivalents of 64 Kbps.

Revenues: In the first quarter, revenues from the operations in Mexico totaled 31.122 billion pesos, a decrease of 5.5% compared with the same period of the previous year. This result was due to decreases of 9.4% and 8.6% in local and long distance services, respectively, as well as the decrease of 13.8% in interconnection revenues resulting from lower traffic volume and the decline of 9.5% in the calling party pays rate. On the other hand, corporate networks revenues increased 10.1%, Internet access service revenues 8.4% and other revenues 30.2%, which includes revenues from Tiendas TELMEX (TELMEX stores).

Local: Local revenues totaled 12.693 billion pesos in the first quarter, a decrease of 9.4% compared with the first quarter of 2007 due to the 9.8% reduction in real terms of revenue per local billed call, to the decrease of traffic due to competition from both mobile telephony and other fixed telephony operators, and to the migration of dial-up Internet access to broadband services.

DLD: DLD revenues totaled 4.144 billion pesos in the first quarter, 5% lower than the first quarter of 2007. The 5.2% increase in traffic was not enough to offset the 9.2% decrease in average revenue per minute.

ILD: In the first quarter, ILD revenues totaled 2.095 billion pesos, a decrease of 14.9% compared with the first quarter of the previous year. Revenues from outgoing traffic declined 8.5% to 1.412 billion pesos compared with the first quarter of 2007 due to the 15.5% decrease in the average revenue per minute, partially offset by the 11.2% increase in outgoing ILD traffic. Incoming international long distance revenues totaled 683 million pesos, a decrease of 25.6% compared with the first quarter of 2007, reflecting the decrease of 21.4% in incoming traffic.

Interconnection: In the first quarter, interconnection revenues decreased 13.8% to 4.791 billion pesos compared with the same period of 2007, mainly due to the decrease of 9.5% in the calling party pays rate and the 4.5% decline in calling party pays traffic.

Corporate networks: In the first quarter, revenues from services related to data transmission through private and managed networks totaled 2.987 billion pesos, 10.1% 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 first quarter totaled 2.920 billion pesos, 8.4% higher than last year's first quarter due to the increase of 55.9% in broadband services but also reflecting the price reduction in broadband Infinitum services (ADSL) that took effect in April 2007.

Costs and expenses: In the first quarter, total costs and expenses were 20.492 billion pesos, a decrease of 2.9% compared with the first quarter of 2007. This decrease was mainly due to higher costs of telephone handsets and equipment for customers, offset by the 12.3% decrease in the amount paid to mobile operators for calling party pays services and for initiatives carried out to optimize resource use.

Cost of sales and services: In the first quarter, cost of sales and services increased 2.3% compared with the same period of 2007, totaling 7.839 billion pesos, due to higher computer and telecommunications equipment costs related to higher sales.

Commercial, administrative and general: In the quarter, commercial, administrative and general expenses totaled 4.731 billion pesos, 2.4% higher than last year's first quarter mainly due to commissions related to higher sales, partially offset by initiatives to optimize resource use.

Transport and interconnection: In the first quarter, transport and interconnection costs totaled 3.401 billion pesos, a decrease of 20% compared with the same period of 2007 as a result of the 12.3% decrease in the amount paid to mobile telephony operators for local calling party pays service and the decrease of 32.4% in international calling party pays traffic.

Depreciation and amortization: In the quarter, depreciation and amortization decreased 1.1% to 4.521 billion pesos due to a lower impact from the update of the value of fixed assets. .

Comprehensive financing result: Comprehensive financing cost produced a charge of 2.567 billion pesos in the quarter. This resulted from: i) a net interest charge of 2.053 billion pesos, 54.8% higher than the same period of 2007, due to recognition of the market value of interest rate swaps and the increase in the level of indebtedness, ii) a net exchange loss of 514 million pesos from the first-quarter exchange rate appreciation of 0.1700 pesos per dollar, offset by the 6.675 billion dollars in dollar-peso hedges (weighted average exchange rate: 10.93 pesos per dollar) and iii) recognition of a gain in the monetary position of 717 million pesos in 2007, effect that is not presented in 2008.

This result was due to increases of 32.5% in local service revenues, 32.1% in revenues from the Internet access business, 1.7% in domestic long distance revenues, for the increase in cable TV revenues of 759.7% and 9.9% in other revenues, mainly comprised of Yellow Pages.

It is important to mention that revenues and costs for Sección Amarilla, or Yellow Pages, are recognized in a deferred manner throughout the year.
