indemnities to guarantee that the objectives, purposes and agreements derived from Telmex’s Escisión will be complied with and completely perfected. 
 CHAPTER II 
 TRANSITORY SERVICES 
 THIRD. SERVICES. Telmex binds itself to render Telmex Internacional the Services that from time to time will be formalized
through the service specification format attached to this Contract as Annex “A,” using to that effect all the administrative, operative, scientific and/or technical knowledge that may be necessary. The Services which are the subject
of this Contract shall be ruled, in general, by its clauses, and specifically, as the case may be, by what is established in the annexes that once executed by the Parties will form an integral part of this Contract and will be included herein by
reference (hereinafter, the “Annexes”), or in the specific contracts entered into from time to time by the Parties. 
 Notwithstanding the foregoing, any discrepancy between the texts of any of the Annexes and the terms and conditions under this Contract or its cover, will be settled in favor of: (i) in the first place, what is expressly established
under this Contract, (ii) in the second place, what is expressly established in the Annexes to this Contract and, in the absence thereof, and (iii) in the third place, pursuant to the principles under Article 20 of the Civil Code.

  

 3 








 The above provided that Telmex binds itself to provide the Services which are the subject of this
Contract using its best effort pursuant to the terms of Article 2615 of the Civil Code. Consequently, for the purpose of Article 2613 of the Civil Code, the obligations that bind Telmex pursuant to this Contract are of means or activity and not
of results. 
 The rendering of the Services referred to under the Annexes shall be conditioned to Telmex’s capacity on the date of the
corresponding service request. In order for a cancellation or change of a Service to take place free of charge, Telmex Internacional shall request it in writing before the times for the performance of the Services covered by this Contract are
agreed upon. If a cancellation or change is requested after the times for the performance of the Services covered by this Contract have been agreed upon, the parties accept and agree that Telmex Internacional shall pay to Telmex the applicable
charges or penalties as detailed under the commercial policies in effect for the Services in question. 
 FOURTH. CONSIDERATION. 
  

	4.1	Charges. 

 4.1.1. Consideration. As
consideration for the Services that Telmex binds itself to render Telmex Internacional, pursuant to the Second Clause of this Contract, Telmex Internacional will pay Telmex the amounts set for each one of those Services as shall be established under
the Annexes, and also the amounts corresponding to other Services the parties agree upon from time to time, and which shall be included in Annexes that the parties agree upon at a given time and that signed by the parties will become an integral
part of this Contract and included by reference herein. If applicable, pursuant to the corresponding tax legislation, the consideration will be levied with the value added tax and/or any other relevant tax. The consideration referred to under
this Clause shall be paid on the date, terms and conditions provided for in this Clause and in the Annexes. 
 4.1.2. Reimbursement of
Expenses. In addition, Telmex Internacional shall reimburse Telmex for the expenses incurred by Telmex directly related with the rendering of the Services which are the subject of this Contract, pursuant to the terms and conditions
established in the Annexes, that signed by the parties are an integral part of this Contract and are included by reference herein. 
  

	4.2	Place of Payment. Any and all consideration, expenses or reimbursements to be made by Telmex Internacional to Telmex, shall be paid at Telmex’s address.


  

	4.3	Denomination. Unless the parties agree otherwise in writing, the consideration shall be invariably denominated in pesos, legal currency of the United Mexican States, or
in the monetary unit of the United Mexican States monetary system that substitutes the peso; and Telmex Internacional shall pay its obligations precisely in that currency. 

  

	4.4	Payment Terms. For the payment of the consideration for the Services which are the subject of this Contract, the following payment conditions shall be complied with:


 4.4.1. Invoices. Telmex shall submit every month to Telmex Internacional, at Telmex Internacional’s offices,
an invoice covering the Services rendered during the previous month (hereinafter, either an “Invoice” or “Invoices”). The Invoice shall include a full description of the Services which are the subject of this Contract,
rendered during the period and also the breakdown of the consideration that Telmex Internacional owes Telmex for those Services. 
  

 4 








 4.4.2. Time and Form of Payment. Telmex Internacional shall pay the Invoices to Telmex in
immediately available Mexican pesos, by check or in cash, deposit in an account or in any other manner agreed upon by the parties, within the thirty (30) calendar days following the date in which Telmex submits the corresponding Invoice duly
supported by the terms of this Contract. 
 4.4.3. Penalty Interest. If Telmex Internacional does not honor its payment obligation
as mentioned in the immediately preceding paragraph, Telmex may charge penalty interest, in addition to the principal amount of the Invoices, from the date of maturity of the Invoices to the date in which they are paid in full, at an annual rate
equal to the most recent annual Tasa de Interés Interbancaria de Equilibrio (TIIE)—Interbank Interest Rate from the date in which the breach begins, multiplied by 1.5 (one point five), over a monthly calculation basis, plus the
corresponding VAT. 
 Penalty interest shall be calculated on the outstanding amounts and shall be computed per calendar day
on a 360 (three hundred sixty) day per one (1) year basis, and for the number of days actually elapsed from the maturity date of the Invoices to the date in which the amounts are made available to Telmex, and it is understood that the penalty
interest shall vary every month based on the variations of the rate of reference during the period in which the breach continues. 
 The above provided that, in no case, the interest rate used as a basis to determine the penalty interest may be less than the highest interest rate of the bond or instrument that the Federal Government places in the money markets that
approximates a 28-day period. 
 FIFTH. INDEMNIFICATION. Neither Party shall be liable before the other party
for damages, indirect or consequential damages, or for the loss of revenues derived or attributable to any of the acts or omissions of the Parties or third parties related to this Contract. In addition, neither Party shall be liable for the damages
caused to Telmex or Telmex Internacional due to force majeure or acts of god, such as explosions, earthquakes or other natural phenomena and those that are provoked by third parties or that are alien to the rendering of the Services which are
the subject of this Contract and that Telmex or, as the case may be, Telmex Internacional, have not been able to reasonably foresee or avoid, such as civilian riots, sabotage or terrorism or other similar situations. In any event, the
Parties’ civil responsibility shall be limited to indemnity for the damages directly caused. 
 SIXTH. TEMPORARY
SUSPENSION. If an event due to force majeure or act of god happens that temporarily hinders Telmex from providing the Services pursuant to the terms of this Contract, the Services which are the subject of this Contract shall
be temporarily suspended and the Parties shall agree on the actions and extraordinary services required to restore, regularize, and guarantee the continuity and quality of the Services. In this event, Telmex Internacional shall pay, upon
Telmex’s request, for the Services actually rendered up to the time they were suspended. In any event, Telmex shall make its best effort to restore the Service. 
 SEVENTH. ASSIGNMENT. Telmex as well as Telmex Internacional bind themselves to fulfill their obligations under this contract by themselves, and consequently, the rights and obligations
derived 

  

 5 








 
from this Contract in no event may be assigned, encumbered or transferred in any manner without the previous consent from the other Party; this consent shall
not be unreasonably denied. As an exception to the above, any of the Parties may assign its rights and obligations under this Contract to any subsidiary or Affiliate of the Parties, without having to obtain authorization from the other party.

 CHAPTER III 
 INDEMNIFICATION
AND SETTLEMENT 
 FINANCING AND DEBT ISSUES 
 EIGHTH. GENERAL INDEMNITIES. 
  

	8.1	Telmex binds itself to indemnify and hold Telmex Internacional harmless of any claim derived from any direct or indirect liability or contingency that had remained with Telmex due
to Telmex’s Escisión; and Telmex Internacional binds itself to indemnify and hold Telmex harmless of any debt or direct contingency that had been expressly transferred to Telmex Internacional due to Telmex’s
Escisión. 

  

	8.2	Mechanics: The obligation to indemnify as described in this clause shall be subject to the following conditions: if there were an event that requires indemnification under
this Contract, the party to be indemnified shall notify in writing to the party that has to indemnify for this event as soon as possible, but not later than fifteen (15) days following the date previous to the date in which (i) the party
to be indemnified has known about the occurrence of this event, or (ii) this party has been notified that a lawsuit was filed in a court, or an action has been brought by an administrative entity alleging the occurrence of an event that gives
the right to the party to be indemnified to an indemnity from the party that has to carry out the indemnification. Notwithstanding the foregoing, if an authority or Regulating Body requests information or documentation related to an event due
to which it is required to indemnity settling a shorter than a 30-day term to deliver such information or documentation, the 15-day term mentioned herein above will be reduced to a period that is equal to half the term granted by that authority or
Regulating Body to deliver the information or documentation requested. The party to pay the indemnity shall have the right, at its option and cost, to object or defend the responsibility of the party to be indemnified; thus it is to be
understood that the lawyer of the party to make the indemnity is approved by the party to be indemnified and it can participate in the defense, bearing the expense. Neither the party to be indemnified, nor its successors or assignees shall
admit any liability, reach an agreement or pay or respond for such supposed responsibility without the prior consent in writing from the party that should pay the indemnity provided that it is objecting or defending in good faith the alleged
responsibility of the party to be indemnified. The party to be indemnified shall cooperate with the party to pay the indemnity in the objection or defense mentioned herein above. Any agreement or transaction to end the legal process or
lawsuit shall be subject to mutual consent, and it shall not be unreasonably denied, by the party to be indemnified and the party that shall pay the indemnity. The obligations of the parties contained in this Clause shall continue for a
five-year period following the effective date of Telmex’s Escisión. 

  

	8.3	 Settlement and Waiver: The parties to this Contract: (i) waive all the rights and actions that oppose the content of this Contract on any claim derived
from Telmex’s Escisión or acts or situations that occurred prior to Telmex’s Escisión, and therefore consider those rights or actions 



  

 6 









	 	 
extinguished and remit to the other party its obligations with the exception of what is contemplated herein, and, (ii) they bind themselves to not try
in the future to file a dispute over any of those rights and responsibilities and (iii) agree that beyond the obligations contained in this Contract, neither Telmex nor Telmex Internacional, will have claims against each other due to economic
obligations, including damages, indirect damages, expenses or legal expenses, and they mutually grant each other therefore, the broadest settlement permitted by law and do not make any reservations thereof for any legal action claim.



 CHAPTER IV 
 OTHER ACTS AND AGREEMENTS 
 NINTH. CONSENTS AND AUTHORIZATIONS. Each one of the Parties binds itself to
take all the reasonable commercial actions to obtain all the authorizations and permits, such as the approval of their corresponding committees and boards of directors, of the necessary Regulating Bodies and third parties, as the case may be, that
may or can be necessary for the implementation and perfecting of this Contract, the compliance with its obligations under it, and to carry out all the operations related to Telmex’s Escisión. 
 In addition, the Parties expressly agree and bind themselves in good faith and diligence that they will carry out all the actions and will take all the
necessary or convenient actions, in order for them to be fully effective and to entirely comply with the agreements contained herein and Telmex’s Escisión. The Parties agree and expressly bind themselves that neither of them
will file a lawsuit, a legal action, demand or denunciation of facts against the other party, on any asset assigned as a result of Telmex’s Escisión. 
 TENTH. COMMON ACTION. The Parties, hereby agree in a common action (litis consorcio pasivo) in the event of a legal proceeding arising from Telmex’s Escisión or any of
the issues covered under this Contract. Therefore, Telmex Internacional, hereby appoints Telmex as its representative. 
 ELEVENTH. INFORMATION. In addition to what is established under this Contract, the Parties will provide each other all the information needed to prepare the financial statements, tax documentation, administrative
acts before the regulating bodies or any other act or fact that is required for the continuous development of its operations. Additionally, Telmex represents and binds itself to make available to Telmex Internacional its accounting records and
work and support documents, if Telmex Internacional wishes to consult or obtain a copy of them, which shall be requested previously and in writing. 
 TWELFTH. NEGATIVE COVENANTS. Each party agrees that it will not take any action that could reasonably be expected to prevent Telmex’s Escisión from qualifying as tax-free under Mexican or U.S.
federal tax laws. Therefore, beginning on the date this Contract is entered into until December 26, 2009, Telmex Internacional shall refrain from participating in any escisión, merger or consolidation with any other Person,
without Telmex’s prior written consent. 
 THIRTEENTH. PROPERTY OF THE CORPORATION. All memoranda, public deeds, contracts,
books of corporate minutes, stock registration books, notes, lists, registers and other documents, data, electronic records, magnetic or optical records or papers (and all corresponding copies) including those filed in computer memory, or in other
media, made or compiled by Telmex or made available to Telmex on 

  

 7 








 
Telmex Internacional and the assets that were assigned to it by Telmex’s Escisión, and all the other corporate books that should be kept
