ARTICLE 4. INDEMNIFICATION 4.1. Indemnity by Sellers. Subject to Section 4.4. of this Agreement, Sellers agree jointly and severally to indemnify, hold harmless and defend Buyer, the Company and their respective Affiliates and related corporations, and their respective directors, officers, partners, employees, agents, successors and assigns from and against any and all claims, causes of action, liabilities, damages, losses, judgments, and the costs and expenses 22 incidental to any of the foregoing (including, but not limited, to reasonable legal, accounting, consulting, engineering and other expenses, costs of investigations and costs of providing any bonds or taking other actions necessary to stay any judgments or perfect any appeals (collectively, "Losses") which may be imposed upon, incurred by, or assessed against any Person seeking indemnification hereunder arising out of, in connection with, or relating to: (a) any material or knowing breach or Inaccuracy ("Breach") of any representation or warranty made by Sellers in this Purchase Agreement; or (b) any breach of any existing contracts where any or both of the Sellers or any of their Affiliates and the Company are a party to, whether as listed in EXHIBIT M or otherwise. 4.1.1. Any Breach of any representation or warranty shall only be subject to indemnification pursuant to this Section 4.1 if such Breach gives rise to Losses (i) over and above US$50,000 per event or per incident and (ii) the aggregate of all such Breaches is in excess of US$250,000. 4.1.2. Except as provided in Section 4.1.3., indemnity claims pursuant to Section 4.1 (a) in the case of a Breach of a representation or warranty is limited to an aggregate amount of US$5,000,000. 4.1.3. None of the limits for indemnity claims stated in Section 4.1.1. and/or 4.1.2. are applicable to any Breach of any representation or warranty which is caused by an intention and knowing breach or an intent to defraud. 4.1.4. Seller shall under no circumstances be liable for any Breach of which Buyer has actual knowledge as of the date hereof. 4.1.5. In calculating the amount of Loss from any Breach of a representation or warranty, the thresholds set forth in Section 4.1.1. shall be initial thresholds but any recovery of Loss once it has exceeded those thresholds shall include Losses from the first dollar of Loss. 23 4.2. Right to Offset. In addition to all other rights and remedies available to Buyer hereunder, Buyer and/or the Company shall have the right and option, but no obligation, to reduce the amount of the payment obligation referred to in the Novation by setting off against such amount the indemnity claims permitted under Section 4.1. hereinabove. This right shall be available to Buyer and/or the Company, as long as the obligation to pay all or part of the Novation is also pending, including in cases of interruption or suspension of such obligation to pay. There shall be no right of set-off for indemnified Losses that are otherwise paid by Sellers or their Affiliates before such offset. No right of offset shall be applied to any Breach of a representation or warranty set forth in Section 3.1 if, at the time of selling, making such representation or warranty, Buyer had actual knowledge that the representation and warranty was untrue when made. 4.2.1. Notwithstanding the foregoing, in the case of the contract regarding the granting of a right of use of the optic fiber and provision of services (listed in Exhibit M), a disruption of such services that (i) arises in the ordinary course of business of the service provider (CHILESAT) which is not related to failure of Sellers or their affiliates to preserve their rights in such optic fiber or related assets (the "Backhaul") and (ii) is consistent with reasonable expectations of parties to contracts for the provision of backhaul services, shall not give rise to a right to offset on the payment obligation referred to in the Novation. 4.3. The rights to indemnity hereunder shall survive the Closing and shall terminate on the first anniversary date with respect to claims under Section 4.1(a) and on the third anniversary to the Closing Date with respect to claims under Section 4.1; provided that such rights to indemnity will be extended for the duration of the suspension or interruption of the obligation to pay the outstanding part of the price contemplated in Section 1.2.(c) hereinabove (the "Indemnity Cut-Off"). 4.4. No Modification of Existing Contracts. The terms of this Section 4 are not intended to modify, supplement, add to or amend the terms of the existing contracts between the Company and Sellers, nor to create, amend and/or terminate any rights or obligations thereunder. In any event, the Indemnity Cut-Off shall not increase, reduce or modify the obligations of the Sellers, or any of them, or their Affiliates, under any agreements with the Company, including, but not limited to, those listed in Exhibit M. 4.5. Notice of Claim. If any indemnified Person under Article 4 (the "Claimant") desires to make a claim (a "Claim") against any indemnifying Person under such provisions (the 24 "Indemnitor"), the Claimant shall give written and prompt notice to the Indemnitor setting forth the amount, nature and circumstances of the Claim. The failure to give such prompt notice shall relieve the Indemnitor of its indemnification obligations contained herein only to the extent that failure to give such notice actually prejudices the rights or materially increases the liabilities or obligations of Indemnitor. Upon receipt of such notice, Indemnitor shall acknowledge in writing the Claim (it being understood that the failure of Indemnitor to provide such writing will not affect its liability for Losses). Upon acknowledging in writing its obligation to indemnify Claimant with respect to a Claim, Indemnitor, if the case were to permit this, may elect in writing to assume the defense of such Claim at its own expense, subject to the right of Claimant to participate in the defense of any such matter at its own expense and with counsel of its own choice. Even if the Indemnitor does not exercise its right to assume the defense of the Claim, Indemnitor must assume the defense of the Claim if so requested by Claimant, subject to the right of Claimant to participate in the defense of any such matter at its own expense and with counsel of its own choice. The Indemnitor shall not have the right to settle any Claim without the consent of Claimant if such settlement would result in a liability or cost to Claimant or, when Buyer is Claimant, and would adversely affect the operation of the Business or affect Buyer's interest in or other rights of ownership in the Shares. Even though Indemnitor were to not assume the defense, case permitting and having been notified to do so, he must abide by the results of the Claim. If the Claim were to not permit that the Indemnitor assume the defense of Claimants interest due to a conflict of interest, Indemnitor must indemnify Claimant directly. ARTICLE 5: EXCLUSIVITY AND NON COMPETITION. 5.1 Exclusivity. Sellers and their Affiliates and their respective officers, directors and agents shall not, directly or indirectly, consult or negotiate with or seek or entertain proposals from any person or entity with respect to selling or otherwise directly or indirectly transferring Shares. Such obligation shall expire on the earlier of (a) such time as Leap Chile fails to acquire Shares by reason of a breach of this Purchase Agreement; (b) the Expiration Date, as extended, or (c) at Closing Date. 5.2 Limitation on Competition. (a) Sellers shall not, and shall not cause or permit any of its Controlling Shareholders, Affiliates or related persons or entities, ("Restricted Entities"), directly or indirectly, to compete directly or 25 indirectly with Chilesat PCS in the provision of mobile wireless telecommunications services (or services which are capable of being used and are actually used or marketed for use, in a mobile operation) ("Restricted Business") in the Republic of Chile for a period of two years, provided that this covenant not to compete shall expire with respect to any party which is acquired in whole or material part (more than twenty-five percent (25%)) by an entity which, prior to the date of such acquisition, is a wireless service provider. (b) Acquisitions by an unrelated wireless service provider of less than 25% of the equity or voting power of any of the Restricted Entities or acquisitions by a non-wireless service provider of any percentage of the shares, equity or voting power of any of the Restricted Entities, shall not rescind the non-compete restrictions applicable to such Restricted Entity. (c) Minority holdings by all Restricted Entities of less than 5%, in the aggregate, in a competing wireless service provider shall not violate this provision. (d) The covenant not to compete includes, but is not limited to, any of the following conducts: (i) engage or attempt to engage (including without limitation by means of direct or indirect ownership of an interest in any third party) or encourage any other person or entity to begin a Restricted Business; or (ii) solicit for employment or employ or assist another to solicit for employment or employ, any individual who is employed by the Company. (e) The parties acknowledge that because a remedy of law for any breach of the provisions of this Section 5.2. will be inadequate, in addition to all other remedies available, Buyer shall have the remedies of a restraining order, injunction or other equitable relief to enforce the provisions of this Section 5.2.. This remedy shall be in addition to, and not in lieu of, any other remedy available to Buyer, including monetary damages. (f) The invalidity, ineffectiveness or unenforceability of any one or more phrases, sentences, clauses, paragraphs or subsections of this Section 5.2. shall not affect the validity or enforceability of the remaining portions of this Section 5.2. or any part thereof. If any provision of this Section 5.2. is finally determined to be invalid judicially, ineffective or unenforceable, the determination will apply only in the jurisdiction in which such final adjudication is made, and such provision shall be deemed severed from this 26 Purchase Agreement for purposes of such jurisdiction only, but every other provision of this Section 5.2. shall remain in full force and effect, and there shall be substituted for any such provision held invalid, ineffective or unenforceable, a provision of similar import reflecting the original intent of the parties to the extent permissible under applicable law. ARTICLE 6: RESOLUTION OF DISPUTES AND GOVERNING LAW. All disputes, controversies or claims arising out of or relating to this Purchase Agreement, or for the breach, termination or invalidity thereof, shall be settled by arbitration pursuant to the Rules of Procedure of the International Chamber of Commerce in effect on the date of this Agreement by an arbitrator chosen by agreement of the parties or, if the parties shall fail to agree upon such arbitrator within fifteen (15) days after one party shall request the other to do so or if the person chosen shall fail or refuse to act as an arbitrator, then by an arbitrator appointed in accordance with such Rules. The arbitration shall be conducted in the English language at Miami, Florida, United States of America. The arbitration shall be based on the English version of the Purchase Agreement approved and executed by the parties on the date hereof. The parties to the arbitration shall have a right to conduct discovery. Judgment upon any award rendered may be entered in any court having jurisdiction or application may be made to such court for a judicial acceptance of the award or an order of enforcement, as the case may be. During the period of any arbitration, the parties agree to continue to perform their respective obligations hereunder to the extent that the performance of such obligations is not the subject of dispute or otherwise has not been submitted to arbitration. Each of the parties hereto waives for now and forever any immunity, sovereign or otherwise, that it may have from the jurisdiction of the court in which an arbitral judgment is sought to be enforced.

The parties agree to coordinate such announcements. 28 ARTICLE 8: MISCELLANEOUS 8.1. Waiver.
