Subject to applicable Laws relating to the exchange of information, the Purchaser and the Company agree to review in advance, and to the extent practicable to consult, with the AT&T Parties on all the material information that appears in any filing to be made or made with, or written materials to be submitted or submitted to any Governmental Body in connection with the transactions contemplated by this Agreement. Each of Purchaser and the Company shall keep the AT&T Parties apprised of the status of matters relating to completion of the transactions contemplated hereby. For the avoidance of doubt, this Section 6.1 does not relate to taxes, matters related to which shall be governed by Section 10.1.

6.2 Further Assurances. Each of the AT&T Parties, the Company and Purchaser shall use its commercially reasonable best efforts to (i) take, or cause to be taken, all actions necessary or appropriate to consummate the transactions contemplated by this Agreement and (ii) cause the fulfillment at the earliest practicable date of all of the conditions to their respective obligations to consummate the transactions contemplated by this Agreement. Notwithstanding the foregoing or any other provision of this Agreement to the contrary, nothing in this Agreement shall be deemed to require Seller or any of its Affiliates to take any action or accept any condition that (i) relates to any business of it or its Affiliates that is not directly related to the business of providing AGN services in Mexico, (ii) would require it to divest or alter its investments in any other entity or in any way restrict additional investment in any other entities, or require it to modify any other existing arrangements (or refrain from undertaking any future arrangements) it may have or seek to establish with any other entity, (iii) would be reasonably likely to result in a failure to close the transactions contemplated hereby or by the Nodes Purchase Agreement, (iv) would be reasonably likely to result in a failure or material delay in AT&T Global Network Services Mexico, S. de X.X. de C.V. (“AGNS”), an Affiliate of Seller, acquiring that certain [***] with substantially the same authorizations sought as originally filed by AGNS with SCT on [***], (v) would be reasonably likely to materially hinder AT&T’s ability to utilize the assets contemplated to be acquired by an Affiliate of Seller pursuant to the Nodes Purchase Agreement to [***] or (vi) would otherwise adversely affect in any material respect the benefits to the Seller or its Affiliates intended to be derived as a result of this Agreement and the Nodes Purchase Agreement.

6.3 Non-Solicitation.

(a) Neither Seller nor any Affiliate of Seller shall, directly or indirectly, for a period beginning on the date of this Agreement and ending on the first anniversary of the Closing Date, without the prior written consent of the Company or Purchaser, solicit the employment of any Key Employee; provided, however, that general solicitations or employment advertisements not specifically targeted at any such Key Employee shall not be restricted hereunder (and, for the avoidance of doubt, this restriction shall not apply to the extent the Key Employee in question first initiates discussions of potential employment with Seller or any of its Affiliates). For purposes of this Section 6.3(a), “Key Employee” means any employee of the Company or its Subsidiaries as of the date of this Agreement who is involved in marketing or sales activities.

(b) Neither the Company nor any Affiliate of the Company shall, directly or indirectly, for a period beginning on the date of this Agreement and ending on the first anniversary of the Closing Date, without the prior written consent of AT&T, solicit the employment of any personnel of AT&T or its Affiliates; provided, however, that general solicitations or employment advertisements not specifically targeted at such personnel shall not be restricted hereunder (and, for the avoidance of doubt, this restriction shall not apply to the extent the individual in question first initiates discussions of potential employment with the Company or any of its Affiliates).

(c) The covenants and undertakings contained in this Section 6.3 relate to matters which are of a special, unique and extraordinary character and a violation of any of the terms of this Section 6.3 will cause irreparable injury to the employer of record of the solicited individual (the “Affected Party”), the amount of which will be impossible to estimate or determine and which cannot be adequately compensated. Accordingly, the remedy at law for any breach of this Section 6.3 will be inadequate. Therefore, the Affected Party will be entitled to temporary and permanent injunctions and/or a restraining order or other equitable relief from any court of competent jurisdiction in the event of any breach of this Section 6.3 without the necessity of proving actual damage or posting any bond whatsoever. The rights and remedies provided by this Section 6.3 are cumulative and in addition to any other rights and remedies which Purchaser may have hereunder or at law or in equity.

(d) The parties hereto agree that if any court of competent jurisdiction determines that a specified time period or any other relevant feature of this Section 6.3 is unreasonable, arbitrary or against public policy, then a lesser period of time or other relevant feature which is determined by such court to be reasonable, not arbitrary and not against public policy may be enforced against the applicable party.

(e) Notwithstanding the foregoing, the Company shall designate at least three Company employees with expertise regarding AGN services for Seller or any of its Affiliates to interview and/or, in its sole discretion, hire.

6.4 Publicity.

(a) None of the Purchaser, AT&T Parties, the Company, and/or any of their Affiliates shall issue any press release or public announcement concerning this Agreement or the

transactions contemplated hereby without obtaining the prior written approval of the other parties hereto, which approval will not be unreasonably withheld or delayed, unless, in the sole judgment of Purchaser or Seller, disclosure is otherwise required by applicable Law or by the applicable rules of any stock exchange on which Purchaser, Seller or their Affiliates list securities; provided, however, that, to the extent required by applicable Law, the party intending to make such release shall use its commercially reasonable best efforts consistent with such applicable Law to consult with the other party with respect to the text thereof.

(b) Each of Purchaser, the AT&T Parties and the Company agrees that the terms of this Agreement shall not be disclosed or otherwise made available to the public and that copies of this Agreement shall not be publicly filed or otherwise made available to the public, except where such disclosure, availability or filing is required by applicable Law and only to the extent required by such Law. In the event that such disclosure, availability or filing is required by applicable Law, each of Purchaser, the Company and the AT&T Parties (as applicable) agrees to use its commercially reasonable best efforts to obtain “confidential treatment” of this Agreement with the Securities and Exchange Commission (or the equivalent treatment by any other Governmental Body) and to redact such terms of this Agreement the other party shall request.

6.5 Resignation of Directors. Seller shall cause each of the directors of the Company and its Subsidiaries set forth on Schedule 6.5 to submit a letter of resignation on or before the Closing Date, to become effective on the Closing Date.

6.6 Termination of JVA and Mutual Release. At the Closing, each party hereto shall enter into and execute the Termination and Release substantially in the form of Exhibit A (the “Termination and Release”).

6.7 Post-Closing Resale. In the event that prior to the [***] anniversary of the Closing Date the Purchaser, the Company or any of their Affiliates or successors enters into a Divestiture Agreement or any Transaction Person makes a Divestiture Announcement, in each case regarding a transaction or a series of transactions, whether related or not, the consummation of which results in (i) the Purchaser or any of its Affiliates or successors disposing of any Equity Interest to one or more Third Parties through a sale, exchange or merger or other type of business combination or consolidation, (ii) the Company or any of its successors issuing any Equity Interest to one or more Third Parties through a sale, exchange or merger or other type of business combination or consolidation, (iii) the Purchaser or any of its Affiliates or successors causing the Company or any of its successors to sell (other than the nodes sold pursuant to the Nodes Purchase Agreement) [***]% of its assets (based on the relative Fair Market Value (as defined in Exhibit D hereto) of the assets sold compared to the Fair Market Value of all assets of the Company or any of its successors) to one or more Third Parties, or (iv) any other transaction or series of transactions, whether related or not, that has the effect of accomplishing indirectly a result that would be within the terms of clause (i), (ii) or (iii) of this sentence if done directly (except, in the case of each of clauses (i), (ii), (iii) and (iv), transactions involving only the Purchaser, the Company and their Affiliates or successors) (each of the transactions described in clauses (i), (ii), (iii) and (iv) of this sentence shall be referred to in this Agreement as a “Divestiture Transaction”), the Purchaser shall pay the Seller in cash any Adjusted Differential Amount (as defined below) if such Divestiture Transaction is consummated, which payment

shall be made at the time of such consummation. The Seller and its Affiliates, in their sole discretion, may reduce any amounts due and payable by them to the Purchaser, the Company or any of their Affiliates or successors by the amount the Purchaser is obligated to pay to the Seller pursuant to this Section 6.7. The Purchaser, the Company and their Affiliates and successors shall act in good faith and engage in fair dealing with the Seller at all times in order to give effect to the spirit of the protections afforded the Seller under this Section 6.7 and, consistent therewith, shall not (x) initiate or consummate any transaction or series of transactions that would have the effect of circumventing the provisions of this Section 6.7, or (y) do anything, or cause the Company or any of its Affiliates or successors to do anything, that would adversely affect or delay the Seller’s receipt of the amounts due it under this Section 6.7. The “Adjusted Differential Amount” shall mean an amount calculated as set forth in Exhibit D. For the avoidance of doubt, (i) if the Adjusted Differential Amount is negative, then this Section 6.7 shall create no payment obligation for any party and (ii) no change in the ownership of the Purchaser shall constitute a Divestiture Transaction. Exhibit D includes calculations of payments, solely for purposes of illustration, that would be required under this Section 6.7 based on hypothetical examples of Divestiture Transactions.

6.8 Notification of Certain Matters. The Seller shall give notice to Purchaser, and Purchaser shall give notice to the Seller, as promptly as reasonably practicable after becoming aware of the institution of or the threat of institution of any Legal Proceeding against any of the Seller, the Company or the Purchaser related to this Agreement or the transactions contemplated hereby; provided, however, that the delivery of any notice pursuant to this Section 6.8 shall not limit or otherwise affect the remedies available hereunder to the party receiving such notice, or the representations or warranties of, or the conditions to the obligations of, the parties hereto.

6.9 Payment of Amounts Owed to the AT&T Parties.

ARTICLE X

MISCELLANEOUS

10.1 Taxes and Expenses.

(a) Seller and Purchaser agree that, pursuant to Article 208 of the Mexican Income Tax Law (“Ley del Impuesto Sobre la Renta”), in the event Seller chooses to exercise the Tax Option, Seller will promptly notify Purchaser of such circumstance and that Seller has designated a representative in Mexico for tax purposes in accordance with Article 208 of Mexico’s Income Tax Law to allow for Seller to be subject to Mexican tax on the Transfer of the Purchased Equity on a net profit or capital gain basis, as provided for in the sixth paragraph of Article 190 of said Mexican Income Tax Law. The parties further agree that (i) should a competent Mexican taxing authority request the Company or its Subsidiaries to provide copies of the tax reports (dictámenes fiscales por venta de partes sociales o acciones) prepared by Seller, then Seller shall deliver such copies to the Company and/or its Subsidiary in question within fifteen (15) days after receipt of a copy of the official request for delivery of said documents from the competent Mexican taxing authorities, and (ii) the Company shall cooperate with and promptly provide to Seller all information required by Seller, including information necessary to complete and/or update the tax cost basis study, to timely file any preliminary and/or definitive tax returns in Mexico and the United States.

(b) Except as provided in (c) below, each party shall bear any capital gains and income tax liabilities, and other tax liabilities, which correspond to it pursuant to applicable Law.

(c) Any and all payments of interest by the Purchaser under the Promissory Notes shall be made free and clear of and without deduction for any taxes or any type of imposts on interest payable under Mexican Law, except to the extent of Seller Taxes; provided that if Purchaser shall be required to deduct any such taxes or imposts other than Seller Taxes from such interest payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this paragraph) the Seller receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Purchaser shall make such deductions and (iii) the Purchaser shall pay the full amount deducted to the relevant Governmental Body in accordance with applicable Laws. Purchaser shall indemnify Seller, within 10 days after written demand therefor, for the full amount of any taxes, other than Seller Taxes, paid by the Seller pursuant to this paragraph, as the case may be, on or with respect to interest under any Promissory Note and any penalties, interest and reasonable expenses arising therefrom or with respect thereto. A certificate as to the amount of such payment or liability delivered to the Purchaser by Seller, demonstrating in reasonable detail the calculation of the amounts, shall be conclusive absent manifest error. If the Seller is entitled to an exemption from Mexican withholding tax or is subject to such withholding tax at a reduced rate under an applicable tax treaty, the Seller shall (w) at or prior to the Closing, (x) on an annual basis thereafter as soon as practically possible

once received from the applicable taxing authority and (y) from time to time if requested by the Purchaser, provide the Purchaser with a completed original of any form or certification required to give effect to such exemption or rate reduction. If the Seller receives a refund or credit of taxes as to which it has been indemnified by the Purchaser or with respect to which the Purchaser has paid additional amounts pursuant to this Section 10.1(c), it shall pay over such refund or credit to the Purchaser (but only to the extent of indemnity payments made, or additional amounts paid, by the Purchaser under this Section 10.1(c), giving rise to such refund or credit), net of all reasonable out of pocket expenses of the Seller and without interest (other than any interest paid by the relevant Governmental Body) with respect to such refund or credit; provided that the Purchaser, upon the request of the Seller, agrees to repay the amount paid over to the Purchaser plus any penalties, interest or other charges imposed by the relevant Governmental Body to the Seller in the event the Seller is required to repay such refund or credit to such Governmental Body.

(d) Except as otherwise provided in this Agreement, the AT&T Parties, on the one hand, and Purchaser, on the other hand, shall each bear its own expenses incurred in connection with the negotiation and execution of this Agreement and each other agreement, document and instrument contemplated by this Agreement and the consummation of the transactions contemplated hereby and thereby, it being understood that in no event shall the Company or its Subsidiaries bear any of such costs and expenses.

10.2 Alestra, ATI and Servicios liabilities. Except to the extent resulting from the willful misconduct, gross negligence or fraud of any AT&T Indemnified Party, the Company agrees to indemnify the AT&T Indemnified Parties against any claim (including commercial, tax, labor and regulatory claims) asserted by any Person against the AT&T Indemnified Parties seeking payment of any liability of the Company, ATI or Servicios, whether presently known or unknown, contingent or otherwise (other than any such liability that has been expressly assumed by an AT&T Indemnified Party in writing), or which results from any AT&T Indemnified Party having served as a board member of the Company and/or ATI and/or Servicios.

10.3 Specific Performance. The parties acknowledge and agree that a breach of this Agreement would cause irreparable damage to the compliant party and that the compliant party will not have an adequate remedy at law. Therefore, the obligations of the parties under this Agreement shall be enforceable by a decree of specific performance issued by any court of competent jurisdiction, and appropriate injunctive relief may be applied for and granted in connection therewith. Such remedies shall, however, be cumulative and not exclusive and shall be in addition to any other remedies which any party may have under this Agreement or otherwise.

10.4 Right of Set-Off Against Company. In the event Seller is unable, for whatever reason, to ultimately obtain payment of any unpaid portion of any Promissory Note after one calendar month from the scheduled date of payment of any installment, in addition to any remedies Seller may have against the Purchaser and/or the Company in connection with the Promissory Notes (but without any duplicate recovery), Seller and/or its Affiliates shall be entitled to tender to the Company, and the Company shall accept, a portion or all of the amounts due under the Promissory Notes at full value, plus any accrued and unpaid interest thereunder, as payment for any services or other payments due the Company pursuant to any contractual or

other relationship the Company and Seller and/or its Affiliates may have at such time and from time to time thereafter, without recourse or liability to Seller.

10.5 Arbitration; Submission to Jurisdiction; Consent to Service of Process; Waiver of Jury Trial.

(a) Any controversy, dispute or claim arising under or in connection with this Agreement (including, without limitation, the existence, validity, interpretation or breach hereof and any claim based on contract, tort or statute) shall be resolved by a binding arbitration in English, to be held in New York, New York pursuant to the Rules of Arbitration of the International Chamber of Commerce (the “ICC Rules”). The number of arbitrators shall be three. One arbitrator shall be appointed by the Purchaser, one arbitrator shall be appointed by the AT&T Parties and the third arbitrator shall be appointed by the first two appointed arbitrators. If, within thirty (30) calendar days after the appointment of the second arbitrator, the two arbitrators shall not have appointed the third arbitrator, the third arbitrator shall be appointed by the International Chamber of Commerce International Court of Arbitration in accordance with the ICC Rules. Each party shall bear its own expenses incurred in connection with arbitration and the fees and expenses of the arbitrators shall be shared equally by the parties involved in the dispute and advanced by them from time to time as required. It is the mutual intention and desire of the parties that the tribunal of three arbitrators be constituted as expeditiously as possible following the submission of the dispute to arbitration. Once such tribunal is constituted and except as may otherwise be agreed in writing by the parties involved in such dispute or as ordered by the arbitrators upon substantial justification shown, the hearing for the dispute will be held within sixty (60) days after submission of the dispute to arbitration. The arbitrators shall render their final award within sixty (60) days, subject to extension by the arbitrators upon substantial justification of extraordinary circumstances, following conclusion of the hearing and any required post-hearing briefing or other proceedings ordered by the arbitrators. Any discovery in connection with arbitration hereunder shall be limited to information directly relevant to the controversy or claim in arbitration. The arbitrators will state the factual and legal basis for the award. The decision of the arbitrators in any such proceeding will be final and binding and not subject to judicial review and final judgment may be entered upon such an award in any court of competent jurisdiction, but entry of such judgment will not be required to make such award effective. Any action against any party hereto ancillary to arbitration pursuant to this Section 10.5(a) (as determined by the arbitrators), including any action for provisional or conservatory measures or action to enforce an arbitration award or any judgment entered by any court in respect of any thereof may be brought in any federal or state court of competent jurisdiction located within the State of New York, and the parties hereto hereby irrevocably submit to the non-exclusive jurisdiction of any federal or state court located within the State of New York over any such action. The parties hereby irrevocably waive, to the fullest extent permitted by applicable law, any objection which they may now or hereafter have to the laying of venue of any such action brought in such court or any defense of inconvenient forum for the maintenance of such action. Each of the parties hereto agrees that a judgment in any such action may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall prevent any party from seeking provisional relief, including injunctive relief, from any court of competent jurisdiction, and any such request shall not be deemed incompatible with the agreement to arbitrate or a waiver of the right to arbitrate.

(b) The parties will keep confidential, and will not disclose to any Person, except their attorneys or as may be required by Law, the existence of any dispute, claim or controversy under this Section 10.5, the referral of any such dispute, claim or controversy to arbitration or the status or resolution thereof; provided that if the arbitrators award any sort of relief in the nature of a restraining order or preliminary or permanent injunction, the existence thereof may be made known to third parties as necessary to achieve the purpose of the relief. Notwithstanding this paragraph, in order to enforce the arbitration award, the parties may file the arbitration award with a court having jurisdiction thereof.
