Dear Shareholders:

The board of directors of Tele´fonos de Me´xico, S.A. de C.V. (‘‘Telmex’’) decided on September 6,2000, to propose to shareholders to divide Telmex, establishing a new independent company called Ame´ricaMovil, S.A. de C.V. (‘‘America Movil’’). We refer to this transaction as the ‘‘Spin-off.’’ Ame´rica Movil willfocus on the Mexican wireless business and on international opportunities in wireless and othertelecommunications businesses. Telmex will focus on the domestic Mexican fixed-line business, includingInternet access and data transmission, and related international initiatives.

The Spin-off is described in the Information Statement that accompanies this letter. It will beimplemented using a procedure under Mexican corporate law calledescision, in which:

• America Movil will be established as a new company;

• specified assets of Telmex (including shares of specified subsidiaries) will be transferred to Ame´ricaMovil; and

• each holder of any class of Telmex shares will receive the same number of Ame´rica Movil sharesof the corresponding class.

If you own L Shares or A Shares of Telmex, you will receive L Shares or A Shares of Ame´rica Movil, withrights that are generally similar to the Telmex shares. If you own L Share ADSs of Telmex, you will receiveL Share ADSs of Ame´rica Movil. You will continue to own the same Telmex shares and ADSs after theSpin-off as before.

On September 25, 2000, an extraordinary meeting of Telmex shareholders will be held to approve theSpin-off and for related purposes. Approval requires the affirmative vote of a majority of the aggregate votingpower of the outstanding AA and A Shares. Carso Global Telecom, S.A. de C.V. and SBC International, Inc.,as beneficial owners, intend to vote their shares in favor of the Spin-off, so approval of the Spin-off at theextraordinary meeting is assured without the affirmative vote of any other shareholder.

You are not being asked for a proxy and are requested not to send one. In accordance withMexican law, no proxy solicitation will be conducted, and as a foreign private issuer, Telmex is exempt fromthe requirements of U.S. law concerning proxy solicitations and information statements. The accompanyingInformation Statement has been prepared to explain the Spin-off to Telmex shareholders.

We are grateful for the loyalty and support of Telmex shareholders and look forward to welcomingthem as shareholders of Ame´rica Movil.

THE SPIN-OFF

Overview

The Spin-off will establish America Movil as a new Mexican corporation, independent of Telmex,engaged in the Mexican wireless business and a variety of other businesses outside Mexico. Neither Telmexnor America Movil will own any capital stock of the other. The relationships between the two companies willbe limited to (a) agreements relating to the implementation of the Spin-off, (b) ordinary course commercialrelationships of the kind that normally occur between a major fixed-line network operator and a major wirelessnetwork operator, such as interconnection and co-location of facilities, and (c) certain transitional arrangementsthat will continue while America Movil develops independent capabilities. See ‘‘— Certain Relationshipsbetween Telmex and America Movil’’ . Telmex and America Movil will initially have the same shareholders,and they will continue to be controlled by the same group of shareholders. See ‘‘ Controlling Shareholders andCertain Beneficial Owners’’ .

In the Spin-off, each shareholder of Telmex will become a shareholder of America Movil. However,there will be a statutory period of at least 45 days between the Approval Date, which is the date America Movilwill be established at a Telmex shareholders’ meeting, and the Share Distribution Date, which is the date eachshareholder will receive shares of America Movil that can be held or transferred separately from Telmexshares.

The purpose of the Spin-off is to improve the ability of each of Telmex and America Movil to addressthe distinct challenges and opportunities it faces. The Mexican wireless business and the related investmentsoutside Mexico that will be transferred to America Movil face very different business and regulatoryenvironments from the Mexican fixed-line telecommunications business, including Internet access and datatransmission, that will remain with Telmex. The differences are already reflected in separate corporate andmanagement structures, fixed assets, operations, marketing and billing. Establishing two separate, publicly-traded companies through the Spin-off is expected to provide benefits for both Telmex and America Movil. Inparticular:

• Management energies and corporate strategy will focus more closely on the specificcircumstances of each business. Separate management will be able to pursue objectives moreappropriate to the profile of each specific business than is possible in the current combinedstructure.

• Each company’s financial strategy will reflect its own risks and potential returns on investment.This should permit each company to access financing more efficiently and to adapt its leverage,dividend policies, capital resources and other financial practices to its specific circumstances.Each company will also be in a better position to use equity securities to acquire other companies,or to establish equity-based and other incentive compensation for employees based on theperformance of a more narrowly focused company.

• Each company will be freed from constraints that arise from being part of the same group as theother. These include regulatory restrictions in Mexico and abroad, such as limitations on access tolicenses important to each company’s business. They also include limitations arising underagreements with creditors or with partners in particular investments.

Shareholder Approval

The board of directors of Telmex decided on September 6, 2000 to propose the Spin-off to the Telmexshareholders. On September 25, 2000, Telmex will hold an extraordinary meeting of its shareholders to approvethe Spin-off. Carso Global Telecom, S.A. de C.V. and SBC Communications Inc. beneficially own AA Shares inexcess of the requisite two-thirds majority required to approve the Spin-off, and they intend to vote all theirshares in favor of the Spin-off. Accordingly, the approval of the Spin-off is assured without the affirmative voteof any other shareholder.

8

Telmex is not asking you for a proxy, and you are requested not to send Telmex a proxy. Inaccordance with Mexican law, notice of the extraordinary meeting will be given by publication in Mexicannewspapers, and Telmex will not conduct any proxy solicitation for the meeting. Only the holders of A Sharesand AA Shares are entitled to be present or to vote at the extraordinary meeting.

Description of the Spin-off

The Spin-off will be implemented using a procedure under Mexican corporate law called escision or‘‘ split-up.’’ In an escision, an existing company is divided, creating a new company to which specified assetsand liabilities are allocated. This procedure differs from the procedure by which a spin-off is typicallyconducted in the United States, where a parent company distributes to its shareholders shares of a subsidiary.The escision will be approved on the Approval Date by a single action of the shareholders at the extraordinarymeeting establishing America Movil and allocating certain assets and liabilities of Telmex to America Movil.Prior to the Approval Date, Telmex will reorganize certain of the intermediate holding companies throughwhich it holds various assets and subsidiaries, so as to facilitate the implementation of the Spin-off.

Effective immediately on the Approval Date:

• America Movil will be established as a separate company, with a fully independent legalexistence and full capacity to own and dispose of its assets. Its initial board of directors will beelected at the same extraordinary meeting that approves the Spin-off.

• Specified assets of Telmex, including the shares of specified subsidiaries, will be transferred toAmerica Movil. All the businesses to be conveyed to America Movil are conducted by separatecorporations, and the continuity of existence of those corporations will be undisturbed by theSpin-off.

• All the shares of America Movil will be owned by the shareholders that own Telmex shares as ofthe Approval Date.

• Certain agreements between Telmex and America Movil will take effect.

Promptly following the Approval Date, the shareholders’ resolution from the extraordinary meetingwill be notarized, registered in the Mexican Public Registry of Commerce and published in the Diario Oficial(Official Gazette). Following the registration and publication of the resolution, Mexican law provides for aperiod of 45 days during which the Spin-off may be challenged by certain parties, as described below. AmericaMovil shares will not be delivered or held separately from Telmex shares before the end of this statutoryperiod.

On the Approval Date, the Spin-off will affect Telmex shareholders as follows:

• Each owner of Telmex L Shares will become the owner of the same number of America MovilL Shares.

• Each owner of Telmex A Shares will become the owner of the same number of America MovilA Shares.

• Each owner of Telmex AA Shares will become the owner of the same number of America MovilAA Shares.

• Each Telmex shareholder will continue to own the same number of Telmex shares.

Prior to the Share Distribution Date, however, there will be no separate certificates for America Movil shares,and the right to receive America Movil shares will be transferred together with Telmex shares. Investors willnot be able to buy or otherwise acquire, or sell or otherwise transfer or deliver, Telmex shares or AmericaMovil shares separately.

The Share Distribution Date

The shares of Telmex and America Movil will be separated following the expiration of the periodduring which the Spin-off may be challenged under Mexican corporate law. See ‘‘— Judicial Proceedings toChallenge the Spin-off’’ . Telmex currently expects to be able to announce the Share Record Date and the ShareDistribution Date no later than November 30, 2000, although no assurances can be given that such anannouncement will be made by such date.

Distribution will generally be made by book entry annotation in the shareholder list maintained byS.D. Indeval, S.A. de C.V., Institucion para Deposito de Valores (‘‘ Indeval’’ ), which is the clearing system forsecurities traded on the Mexican Stock Exchange. Beginning on the Share Distribution Date, it is expected that:

• America Movil A Shares and L Shares will commence trading on the Mexican Stock Exchange.

• Telmex A Shares and L Shares will trade on the Mexican Stock Exchange without the AmericaMovil Shares.

• Shareholders will be able to deliver Telmex shares and America Movil shares separately.

Effects of the Spin-off on Holders of Telmex L Share ADSs

As of the Approval Date, each Telmex L Share ADS will represent, in addition to 20 Telmex LShares, the right to receive 20 America Movil L Shares to be distributed on the Share Distribution Date.

America Movil will arrange with a U.S. depositary bank to issue ADSs, each representing 20 AmericaMovil L Shares. On the ADS Distribution Date, America Movil L Share ADSs will be issued and distributed toeach record holder of Telmex L Share ADSs at the close of business (New York time) on the ADS RecordDate. Trading of America Movil L Share ADSs on the New York Stock Exchange will begin on the ADSDistribution Date. Telmex currently expects that Morgan Guaranty Trust Company of New York, thedepositary of the Telmex L Share ADSs, will announce the ADS Record Date and the ADS Distribution Dateon or about the same date on which Telmex announces the Share Record Date and the Share Distribution Date,although no assurances can be given that such an announcement will be made by such date.

Persons holding Telmex L Share ADSs through the facilities of The Depository Trust Company(‘‘ DTC’’ ) will receive the distribution of America Movil L Share ADSs by book entry only, through thefacilities of DTC. Persons holding Telmex L Share ADSs directly will receive the distribution of AmericaMovil L Share ADSs in the form of certificated American Depositary Receipts (‘‘ ADRs’’ ) representingAmerica Movil L Share ADSs. These ADRs will be mailed to direct holders of Telmex L Share ADSs on or assoon as practicable after the ADS Distribution Date. Persons holding Telmex L Share ADSs through a brokeror other securities intermediary should consult such broker or other securities intermediary concerningdistribution of the America Movil L Share ADSs.

Effects of the Spin-off on Holders of Telmex A Share ADSs

Several depositary banks have issued ADSs representing Telmex A Shares. These ADSs are‘‘ unsponsored’’ by Telmex, meaning that Telmex is not a party to the deposit agreements and has not approvedor participated in the establishment of these ADS programs.

The effect of the Spin-off on holders of Telmex A Share ADSs will depend on the actions taken by thedepositary banks and the provisions of the deposit agreements. Telmex has not yet determined whether asponsored ADS program will be established for the America Movil A Shares.

Effects of the Spin-off on Holders of Telmex Convertible Debentures

In 1999, Telmex issued U.S.$1,000,000,000 aggregate principal amount of 4.25% Convertible SeniorDebentures due 2004 (the ‘‘ Debentures’’ ), which are convertible into Telmex L Share ADSs. The conversionrate is currently 21.07 ADSs per U.S.$1,000 principal amount of Debentures, which corresponds to an effective

10

conversion price of approximately U.S.$47.46 per ADS. As a result of the Spin-off, the conversion rate will beadjusted, reducing the effective conversion price, based on the fair market value of the America Movil sharesdistributed to Telmex shareholders. Under the Indenture governing the Debentures, the fair market value ofAmerica Movil shares is to be determined by the board of directors of Telmex.

Telmex management intends to propose to the board of directors that the fair market value of theAmerica Movil shares be determined based on the relative market prices of Telmex L Shares and AmericaMovil L Shares following the Share Distribution Date. If the board of directors follows this recommendation,then, in accordance with the applicable provisions of the Indenture, the conversion rate will be multiplied by afraction (TM + AM)/TM, where

• AM equals the average last reported sale price of America Movil L Shares over the first 20trading days on which America Movil L Shares trade on the Mexican Stock Exchange; and

• TM equals the average last reported sale price of Telmex L Shares over the first 20 trading dayson which Telmex L Shares trade on the Mexican Stock Exchange ex the America Movil LShares.

Certain Relationships between Telmex and America Movil

Immediately after the Spin-off, Telmex will not own any America Movil shares or America Movil LShare ADSs and America Movil will not own any Telmex shares or Telmex L Share ADSs. Under Mexicanlaw, Telmex will remain jointly and severally liable for the obligations of Telmex assumed by America Movilpursuant to the Spin-off for a period of three years beginning on the Approval Date. Such liability, however,will not extend to any obligation to a person or entity that has given its express consent relieving Telmex ofsuch liability and approving the Spin-off.

Following the Spin-off, there will be a variety of contractual relationships between Telmex andAmerica Movil, both to accomplish the separation of the Spin-off and to provide for ongoing commercialrelationships. These will be fully described in the America Movil Registration Statement. They fall into threebroad categories.

The separation of the two companies and the transfer ofassets and liabilities to America Movil will be effected by the action of the Telmex shareholders at theextraordinary shareholders’ meeting. Telmex and America Movil will also be obligated to further ensure thatthe purposes of the Spin-off are fully achieved, by virtue of shareholder resolutions or other arrangementsproviding for such matters as indemnification, releases, assistance in obtaining consents, exchange ofinformation, covenants relating to the tax treatment of the Spin-off and similar matters.

Transitional Services. Telmex and America Movil will enter into an agreement under which Telmexwill provide a variety of services to America Movil on an interim basis. These services will include certain dataprocessing and corporate support and administrative services. They will generally be provided at cost plus aspecified percentage.

Continuing Commercial Relationships. Telmex and America Movil each have extensivetelecommunications operations in closely related markets, particularly in Mexico. As a result, they will have awide variety of ongoing relationships, many of which are already in place. These include interconnectionbetween networks and use of each other’s services. In general, these relationships will be governed by termssimilar to those on which each company does business with other independent parties.

Approvals and Consents

In connection with the Spin-off, Telmex and America Movil will require consents from certaincreditors and from other participants in certain investments that will be transferred to America Movil. Telmexdoes not expect to obtain all these consents before the Approval Date, and it is possible that some of them will

11

be obtained only after a long period of time, or not at all. Failure to obtain consents from creditors could resultin Telmex or America Movil being in default under certain of their respective debt obligations. Failure toobtain consents for the transfers of certain investments to America Movil could result in the delay or reversalof such transfers.

Where obligations of Telmex will be transferred to America Movil, consent of the relevant creditorswill be required in order for America Movil to succeed to the rights and obligations of Telmex. In these cases,failure to obtain consent from creditors may require that Telmex remain liable for certain obligations ofAmerica Movil, including indebtedness and credit support provided to certain subsidiaries and affiliates ofAmerica Movil. America Movil will agree to indemnify Telmex against liabilities of this kind.

In addition, Telmex will be required to obtain clearance from the Mexican competition authorities.

Withdrawal Rights

Under Mexican corporate law, a holder of Telmex A Shares or AA Shares may, as a result of theSpin-off, have the right to withdraw the capital represented by its shares. In order to exercise the right ofwithdrawal, a shareholder must vote against the Spin-off at the extraordinary shareholders’ meeting at which itis approved, and then give notice of its intention to exercise its withdrawal rights within 15 days ofadjournment of the extraordinary meeting. A shareholder who has complied with these steps is entitled toreimbursement of its shares in proportion to the net assets of Telmex as reflected on the most recent annualbalance sheet that has been approved by the shareholders of Telmex.

Judicial Proceedings to Challenge the Spin-off

Under Mexican corporate law, for a period of 45 days following the registration and publication of theshareholders’ resolution approving the Spin-off, any shareholder or group of shareholders representing at least20% of the entire capital stock of Telmex, or any creditor of Telmex, may commence judicial proceedings inMexican courts to challenge the Spin-off. In connection with such a challenge, a court may temporarilysuspend the Spin-off, if the party bringing the proceedings posts bond as security for damages and losses whichmight be suffered by Telmex as a result of the challenge. The suspension may continue until there is a final,non-appealable judicial declaration that the challenge is unfounded or an agreement between the challengingparty and Telmex. Once the period has expired and the by-laws of America Movil have been notarized andregistered in the Public Registry of Commerce, the Spin-off may no longer be challenged by creditors orshareholders. Telmex does not plan to distribute the America Movil shares until at least 45 days from theApproval Date, and it may further defer the distribution if there are challenges to the Spin-off or for any otherreason.

The legal grounds on which an escision may be challenged, and the remedies a court may impose if itsustains the challenge, are not specified in Mexican corporate law and have not been the subject of extensivepractical experience or commentary. Telmex is unable to anticipate whether any party will challenge the Spin-off or, if so, what standards the Mexican courts will apply to rule on the challenge, what procedures they willfollow in conducting proceedings or what remedies they will impose.

Certain U.S. and Mexican Tax Consequences

Mexican Tax Consequences

The following discussion summarizes the principal Mexican tax consequences of the Spin-off to aholder of Telmex shares or Telmex ADSs that does not reside in Mexico for purposes of Mexican taxation (a‘‘ non-Mexican holder’’ ), but it does not purport to be a comprehensive description of all the taxconsiderations that may be relevant to the holders of Telmex shares or Telmex ADSs.

The receipt by non-Mexican holders of America Movil shares or America Movil L Share ADSs inconnection with the Spin-off will not be subject to Mexican personal income tax, corporate income tax orcapital gains tax.

12

Telmex will not be subject to Mexican income tax on the transfer of assets to America Movil in theSpin-off, provided that at least 51% of the aggregate issued and outstanding A and AA Shares of each Telmexand America Movil are not transferred for a period of one year after the Mexican tax authorities have beennotified of the Spin-off. Telmex intends to notify the tax authorities after the expiration of the 45-day statutoryperiod described in ‘‘— Judicial Proceedings to Challenge the Spin-off’’ , and Carso Global Telecom, S.A. deC.V., a beneficial holder of more than 51% of the aggregate issued and outstanding A and AA Shares ofTelmex as of the date of this Information Statement, has informed Telmex that it intends to comply with theone-year restriction on transfer.

For purposes of Mexican taxation, a natural person resides in Mexico if he or she has established hisor her home in Mexico, unless he or she has resided in another country for more than 183 consecutive ornonconsecutive days in any calendar year, and can demonstrate that he or she has become a resident of thatcountry for tax purposes. A legal entity resides in Mexico for Mexican tax purposes if it was incorporated inMexico, or has its principal administrative office or the effective location of its management is in Mexico. AMexican citizen is presumed to be a resident of Mexico unless such person can demonstrate otherwise. If anon-resident of Mexico has a permanent establishment or fixed base in Mexico, he or she will be subject toMexican taxes in accordance with applicable Mexican tax laws.

There are no Mexican stamp, issue, registration or similar taxes or duties payable by holders ofTelmex shares or Telmex ADSs in connection with the Spin-off.

United States Tax Consequences

This summary describes the principal U.S. federal income tax consequences of the Spin-off to U.S.holders (as defined below) of Telmex shares or Telmex ADSs. It does not purport to be a comprehensivedescription of all of the tax consequences of the Spin-off that may be relevant to such a U.S. holder. Thissummary applies only to U.S. holders of Telmex shares or Telmex ADSs holding the Telmex shares or TelmexADSs as capital assets and does not apply to special classes of U.S. holders such as dealers in securities orcurrencies, holders with a functional currency other than the U.S. dollar, holders of 10% or more of the sharesof Telmex (whether held directly or through ADSs or both), tax-exempt organizations, financial institutions,holders liable for the alternative minimum tax, securities traders electing to account for their investment inTelmex shares or Telmex ADSs on a mark-to-market basis, and persons holding Telmex shares or TelmexADSs in a hedging transaction or as part of a straddle or conversion transaction.

For purposes of this discussion, a ‘‘ U.S. holder’’ is a holder of Telmex shares or Telmex ADSs that is(i) a citizen or resident of the United States of America, (ii) a corporation organized under the laws of theUnited States of America or any state thereof, or (iii) otherwise subject to U.S. federal income taxation on a netincome basis with respect to the Telmex shares or Telmex ADSs.

Each U.S. holder should consult such holder’s own tax advisor concerning the overall taxconsequences to it, including the consequences of the Spin-off arising under foreign, state and local laws.

Cleary, Gottlieb, Steen & Hamilton, U.S. tax advisors to Telmex (‘‘ U.S. tax counsel’’ ), will deliver onthe Approval Date an opinion regarding certain U.S. federal income tax consequences of the Spin-off. Thatopinion will be rendered on the basis of facts, representations and assumptions set forth or referred to in theopinion. In rendering this opinion, U.S. tax counsel will require and will rely upon factual representations as setforth in certificates of officers of Telmex and SBC International, Inc. Based on the information currentlyavailable, Telmex expects that the opinion of U.S. tax counsel will be that a U.S. holder should be treated asreceiving a tax-free distribution on the Approval Date of the America Movil shares (or America Movil ADSs)pursuant to section 355(a) of the U.S. Internal Revenue Code of 1986, as amended (the ‘‘ Code’’ ). TheApproval Date is the date on which Telmex shareholders become the deemed owners of the America Movilshares or America Movil ADSs. Because the Spin-off should be viewed as occurring on the Approval Date,U.S. holders should not be considered to receive any additional distribution on the Share Distribution Date orthe ADS Distribution Date.

13

Based on the foregoing, U.S. holders should not recognize any income, gain or loss for U.S. federalincome tax purposes in connection with the Spin-off. A U.S. holder’s aggregate basis in the Telmex shares (orTelmex ADSs) and America Movil shares (or America Movil ADSs) after the Spin-off will equal such U.S.holder’s former basis in the Telmex shares (or Telmex ADSs) prior to the Spin-off. Such aggregate basis willbe allocated among the Telmex shares (or Telmex ADSs) and the America Movil shares (or America MovilADSs) in proportion to their respective fair market values.

A U.S. holder’s holding period in a Telmex share (or Telmex ADS) will continue after the Spin-off,and the holding period of a America Movil share (or America Movil ADS) will include the holding period ofthe Telmex share (or Telmex ADS) with respect to which it was received. A U.S. holder that receives AmericaMovil shares in respect of Telmex shares should not be treated as receiving ‘‘ section 306 stock’’ (a term thathas a technical definition under the Code).

Treasury regulations require each U.S. holder of Telmex shares (or Telmex ADSs) that receivesAmerica Movil shares (or America Movil ADSs) pursuant to the Spin-off to attach to its U.S. federal incometax return for the year in which the Spin-off occurs a detailed statement setting forth information concerningthe applicability of Code section 355 to the Spin-off. Telmex will make available to such holders a statementproviding the information necessary to comply with this requirement and information with respect to theallocation of tax basis between Telmex shares (or Telmex ADSs) and America Movil shares (or America MovilADSs).

The opinion of U.S. tax counsel described above will not be binding on the Internal RevenueService (the ‘‘Service’’) or the courts, and no rulings will be sought from the Service on any of the issuesdiscussed in this section. It is possible that the Service would seek to recharacterize the Spin-off as ataxable dividend of America Movil shares to the shareholders of Telmex (to the extent of Telmex’scurrent and accumulated earnings and profits, as measured in accordance with U.S. federal income taxprinciples). If the Service were to prevail, a U.S. holder would be treated as receiving ordinary dividendincome on the Approval Date in an amount equal to the fair market value of the America Movil shares (orAmerica Movil ADSs) received.

Based on the opinion of U.S. tax counsel, a holder of Telmex shares (or Telmex ADSs) that is not aU.S. holder will not be subject to U.S. federal income or withholding tax in respect of the distribution ofAmerica Movil shares (or America Movil ADSs) in connection with the Spin-off.

Thetelephone number of Telmex at this location is (525) 703-3990. The Telmex 20-F, which is incorporated byreference into this Information Statement, contains a description of its business and a review of its financialcondition and performance through December 31, 1999. Unaudited interim financial information andcommentary on Telmex’s financial condition and performance during 2000 are contained in Telmex’s reportson Form 6-K filed on April 28, 2000, June 9, 2000 and July 21, 2000, which are also incorporated by referenceinto this Information Statement.

Recent Developments

Regulation

On September 11, 2000, the Mexican telecommunications regulatory agency (‘‘ Cofetel’’ ) adoptedregulations on rates, quality of service and disclosure of information that apply to Telmex as a dominantcarrier. The regulations impose additional restrictions on Telmex’s customer rates, interconnection rates,commercial strategy and operations. Telmex is currently analyzing the regulations and possible challenges tothe regulations. Telmex is not able to predict when or how any legal challenges to the regulations will beresolved or whether it will be adversely affected by these regulations or any further measures to regulate it as adominant provider.

Telgua

Telmex owns a controlling interest in Telgua, a telecommunications company in Guatemala, whichwill be transferred to America Movil in the Spin-off. In June 2000, the executive branch of the Guatemalangovernment issued declarations concerning Empresa Guatemalteca de Telecommunicaciones (‘‘ Guatel’’ ), aGuatemalan state agency that conducted the privatization of Telgua. The declarations state that certain actionsof Guatel relating to the privatization of Telgua were contrary to the interests of the Guatemalan state. InSeptember 2000, the Guatemalan government commenced judicial proceedings against Guatel, Telgua andcertain other parties involved in the privatization alleging certain improprieties in connection with theprivatization and seeking a variety of remedies, including reversal of the privatization. Telgua has not beenformally notified of such proceedings. Telmex is not able to predict whether any further legal or administrativeprocess will follow, but it will monitor further developments and expects that Telgua will have an opportunityto be heard and to participate in any such process.

PRO FORMA FINANCIAL INFORMATION

The unaudited pro forma financial statements set forth below show how the Spin-off would haveaffected the financial condition and results of Telmex if it had occurred earlier. They are based on (a) theconsolidated financial statements of Telmex as of and for the year ended December 31, 1999 and as of and forthe six months ended June 30, 2000, (b) the financial statements as of the same dates and for the same periodsof the companies that will be subsidiaries of America Movil following the Spin-off, as currently contemplated,(c) the allocation of assets and liabilities between Telmex and America Movil in the Spin-off, as currentlycontemplated, (d) the allocation of certain assets and liabilities in the reorganization that will precede the Spin-off, as currently contemplated, and (e) the assumed refinancing or disposition of indebtedness of Telmex heldby a subsidiary that will be transferred to America Movil. This information is preliminary and may be subjectto change. The pro forma financial statements consist of:

• condensed consolidated balance sheets as of June 30, 2000, giving effect to the Spin-off as if ithad occurred on June 30, 2000; and

• condensed consolidated statements of income for the year ended December 31, 1999 and for thesix months ended June 30, 2000, each giving effect to the Spin-off as if it had occurred onJanuary 1, 1999.

America Movil and Telmex will initially have the same number ofoutstanding voting shares (AA Shares and A Shares) and limited-voting shares (L Shares). From the ApprovalDate to the Share Distribution Date, the America Movil shares will be owned by the same persons and in thesame amounts as the Telmex shares. After the Share Distribution Date, the America Movil shares can be ownedand traded separately from the Telmex shares.

Control

As of June 30, 2000, the Telmex AA Shares represented 22.21% of the total capital stock and 90.22%of the full voting shares (Telmex AA Shares and Telmex A Shares). The Telmex AA Shares are held by a trust(the ‘‘ Control Trust’’ ) for the benefit of the following parties (the ‘‘ Controlling Shareholders’’ ): (a) a groupof Mexican investors (the ‘‘ Mexican Controlling Shareholders’’ ), who collectively own 67.55% of theTelmex AA Shares, and (b) SBC International, Inc. (‘‘ SBCI’’ ), a subsidiary of the U.S. telecommunicationscompany SBC Communication Inc., which owns 32.45% of the Telmex AA Shares. The Mexican ControllingShareholders include (a) Carso Global Telecom, S.A. de C.V. (‘‘ CGT’’ ), which owned 59.53% of the TelmexAA Shares as of June 30, 2000, and (b) various other Mexican investors, who owned 8.02% of the Telmex AAShares. CGT holds interests in the telecommunications industry and was spun off from Grupo Carso, S.A. deC.V. (‘‘ Grupo Carso’’ ) in 1996. Through its ownership of all the outstanding Telmex AA Shares, the ControlTrust owns a majority of Telmex’s outstanding regular voting equity securities.

The Control Trust provides that the trustee must vote the Telmex AA Shares as a block as instructedby a technical committee, except that the trustee must vote as instructed by the Controlling Shareholders on theelection of directors, alternate directors, members and alternate members of the executive committee andstatutory auditors. The technical committee is controlled by the Mexican Controlling Shareholders, except thatthe votes of representatives of SBCI are required before the trustee may vote to approve dividends, modifyTelmex’s by-laws, merge or liquidate Telmex, issue voting shares of Telmex or terminate the listing ofTelmex’s shares on any stock exchange.

Under the Control Trust, a Controlling Shareholder may transfer its Telmex AA Shares subject tocertain rights of first refusal in favor of the other Controlling Shareholders. The Control Trust may beterminated by any party as of December 20, 2000, or jointly by the Controlling Shareholders at any time.

CGT and SBCI are currently negotiating new terms to govern their relationship as owners of AAShares of Telmex and America Movil. If they reach an agreement, they may terminate the Control Trust andconclude one or more new agreements.

Since January 1, 1997, the ownership of Telmex A Shares and Telmex L Shares by CGT and itsaffiliates, including Grupo Carso and Grupo Financiero Inbursa, S.A.
