General Conditions for the Provision of Satellite Signal Conduction via Mexican Satellite System, in which Satelites Mexicanos, S.A. de C.V. hereinafter SATMEX, shall provide the service via the satellites for which it has been granted a Concession by the Mexican Federal Government. CHAPTER I GENERAL PROVISIONS 1st ARTICLE The purpose of this document is to set forth the general conditions which will govern the service provided by SATMEX. 2nd ARTICLE The service which SATMEX will provide, consists of signal conduction via satellite, on C and KU Bands of the Mexican Satellite System, observing the provisions of its Concession Certificate, the Federal Telecommunications Law, the Communication Via Satellite Regulation, the Federal Law of Radio and Television and its Regulation, the UIT Consitution and Agreement, the International Telecommunications Regulation, International Treaties on the subject matter approved by the Senate of the Republic, and other administrative provisions on the subject matter. 3rd ARTICLE The definitions of the technical terms used in the contracts, agreements or accords, shall be understood according to the definitions contained in the documents indicated in above 2nd Article, and any definitions issued by the Telecommunications Standardization, Radio Communications sectors and the Development of Telecommunications of UIT, as well as the Glossary of Terms used in Telecommunications published by the Ministry of Communications and Transportation through the Federal Telecommunications Commission and/or Telecommunications of Mexico. 4th ARTICLE SATMEX will provide the service to establish a communication link in national or international territory for customers who so require. Customers have the responsibility to obtain the necessary concessions, permits or authorizations from the Federal Mexican Government or the authorities on the subject matter of each country. 5th ARTICLE The earth stations and equipment to establish satellite links must be authorized by the Ministry of Communications and Transportation, must comply with Mexican Official Standards of technical specifications for services related to the conduction of signals between fixed points via the use of the Mexican Satellites. For the case of earth stations located abroad, Recommendation 580-2 of CCIR (29-25 log of 6) must be complied with. CHAPTER II PROVISION 6th ARTICLE The services will be provided under the following conditions: Permanent - 24 hours a day, every day of the month or, less than 24 hours by the hour or fraction thereof, at the same time, during every day of the month. Occasional. For a determined time(s) of day and date(s) previously established for that occasion(s). For each of the foregoing, tariffs and regulations will be established. 7th ARTICLE Permanent service will be provided based on three categories according to continuity priority in the event of a contingency or partial or complete breakdown of the assigned satellite, as follows: FULLY PROTECTED SERVICE. The service which has a total backup on the same satellite or on another SATMEX satellite, except when the failure is caused by the actions or failure of the customer to fulfill SATMEX's conditions. NON-INTERRUPTED SERVICE. The service whose transponder has backup amplifiers and is not interrupted to give priority to a protected service, but does not have in the event of failure immediate protection on another transponder or satellite. INTERRUPTED SERVICE. The service subject to interruption as required at any time to give immediate protection to a protected service and to a non-interrupted service since these are priorities. In its normal operation the transponders has backup amplifiers. Each category of permanent service has a different tariff defined in the Tariff Manual and Technical Addendum (Addendum II of the corresponding agreement) When requesting the service, the customer shall indicate to SATMEX the band and the category of service it wishes to contract; however,, each service category is subject to the availability of the capacity of the space segment determined for each category at the time of contracting. SATMEX will indicate to future customers the availability of the space segment by category, tariffs and conditions for the provision of the service. The space segment for national security and social welfare has maximum priority over any service category in the event of a emergency. Occasional service will be provided subject to availability of the capacity to provide this type of service, for the dates and time requested. SATMEX will attend to the demand for the space segment for occasional services through the International Center for Reserve and Programming of Occasional Services (Booking) . 8th ARTICLE. The space segment will be assigned based on information carriers and standard transmission speeds, by complete transponder or by fractions of bandwidth and/or transponder power, measured in megahertz (MHz) and watt decibels (dBw), respectively. 9th ARTICLE. When contracting for the service, the client shall deliver a technical memory describing the network, its topology, the earth stations and equipment, access means to the satellite, the required capacity and link budget for each carrier, according to the format previously delivered by SATMEX. As well, SATMEX will publish a technical manual of its satellites, with the technical information, coverages, transponder parameters, sites, etc., required for customers to develop their network and calculate the antenna diameter and link requirements. 10th ARTICLE. SATMEX, based on the requested capacity and the technical information presented by the customer, shall assign the satellite, transponder for each carrier contracted for, the transmission and reception frequencies, polarization and operating parameters, such as modulation, forward error correction (FEC), bandwidth (MHz), and earth station power requirements (dBw). The frequency receivers of the customers earth station must be efficient and for kilohertz. The operation of equipment with adjustable frequencies via crystals or with tuning limitations is not recommended because this does not allow the relocation of service in the event of interference and can also result in greater consumption of the bandwidth chargeable to the customer. 11th ARTICLE. The technicians responsible designated by the customer to operate its earth stations of its satellite network may not exceed the normal parameters for access to the satellite assigned to each carrier. The personnel of SATMEX Center for Primary of Alternate Satellite Control of SATMEX, on detecting excesses, will immediately coordinate with the persons responsible for the earth station or the network, to make the necessary corrections. If the customer does not make the required correction, the customer shall be subject to fines for the use of excessive bandwidth or power or for damages caused to other customers. The fines will be for an amount resulting from applying the highest rate for the affected bandwidth and/or power affected, in addition to, if applicable, any compensation which SATMEX must pay the affected customer or customers. Payment of fines does not imply authorization to continue operating the service outside of the assigned parameters for access to the satellite. If the customer finds it necessary to operate with a higher level of satellite power, it may request SATMEX to authorize (with link budgets, and if authorized apply any adjustments to their invoice. The customer will include in the technical memory of its satellite network for each one of the earth stations that access the satellite assigned to SATMEX, the domicile(s), responsible technicians, telephone number(s) and facsimile (fax). SATMEX, shall deliver to customer in writing upon execution of the agreement, the access frequencies to the satellite and its operation parameters. 12th ARTICLE. Prior to accessing the satellite, customer shall coordinate with the Primary or Alternate Control Center the required technical tests of their earth stations consistently with the procedure and protocol established by SATMEX. SATMEX will grant its customers a maximum period of three (3) calendar days, at no cost, starting from the date on which they are notified of the assignment of the space segment contracted for, with the frequency and operating parameters, to allow them to conduct the tests of their earth station(s) and adjustments, in coordination with the Primary or Alternate Control Center. At the conclusion of this period, irregardless of whether the tests have been conducted, it will be understood that the service has been made available to the customer and the billing period will commence. 13th ARTICLE. The earth stations that do not satisfy the isolation, radiation pattern tests or any other parameters that affect or can affect other signals or satellites will not be authorized to operate with the satellites until corrected without any liability for SATMEX. As well, if an already approved earth station during its operation produces interference to other signals will suspend its access until corrected. In this case the customer must give the Primary or Alternate Control Center assistance to eliminate such interference. In the event the responsible party for the earth station(s) does not fulfill the indications of the Primary or Alternate Control Center to correct or deactivate the earth station producing the interference, the customers shall pay SATMEX a fine in an amount equal to 1% of the monthly tariff for each hour or portion thereof of delay. In the event of earth stations that access a satellite for occasional service, these earth stations must always coordinate testing and power adjustments at least fifteen (15) minutes before the hour indicated for the event. If this testing is not done, the Primary or Alternate Control Center shall not allow access to the earth station. The customer agrees to oversee the operating state of the earth stations and that these do not produce interferences to its own signals, other customer's signals o to other satellites. ARTICLE 14. When a customer is affected in its signals by an unknown or undetermined interference and that cannot be corrected immediately, the customer shall have the option of being relocated immediately to a free space to continue its communications. This should be immediately reported to the monitoring area of the Primary or Alternate Control Center so that they can coordinate with the assignment area, and support any relocation activities. In this event, SATMEX shall give the customer new frequencies and operating parameters either temporary or definite. Expenses implied by any relocation of frequencies shall be the customer's responsibility. ARTICLE 15. Any modification in service or relocation must be requested thirty (30) days in advance and the corresponding technical memory and link budget shall be included for the modified carriers or new sites. The customer must not make any changes without previous coordination with SATMEX. CHAPTER III. AGREEMENTS ARTICLE 16. To contract the service the customers must have a public network concession or license as stated in articles 24 and 31 of the Federal Telecommunications Law and in accordance with the established in the Regulations for Satellite Communications. Any concession or license shall be the customer's responsibility. A copy of this document must be presented to SATMEX so that it becomes an integral part of the agreement as an Addendum. ARTICLE 17. Terms of the agreements will be specified in each document executed by the customers in accordance with the following: I. The minimum term shall be determined by the type of service requested by the customer and shown in the corresponding tariff. II. The agreement for permanent services offered by SATMEX shall have a 1 year minimum and three (3), five (5) and ten (10) years for long term agreements. The agreements can be terminated in the event of satellite failure and as long as there is no replacement capacity.

Occasional or periodic services provided for periods of hours, half-hours or minutes: for each minute of interruption, the compensation will be equal to the rate per minute, applied to the number of minutes during which the interruption persisted. I. SATMEX will not consider requests for compensation when the interruption results from negligence of the customer or a breakdown of its apparatus and equipment, the maintenance and operation whereof correspond to the customer. I. Compensation, when applicable, will be credited to the customer in the invoice payable of the second and third month subsequent to the month in which the interruption occurred. I. As to occasional services, if the customer requests a suspension of already initiated service prior to the conclusion of the contracted schedule, customer will not be entitled to any compensation. I. Refunds will proceed only when it is not possible to apply the compensation to other periods or services of the customer. CHAPTER VIII. PREMATURE TERMINATION. 36th ARTICLE. SATMEX may at any time terminate the agreement with no liability on its part, for justified causes or for reasons duly motivated and justified giving notice to customer thirty (30) business days in advance. 37th ARTICLE. Customer may terminate the respective agreement, notifying SATMEX in writing at least thirty (30) business days in advance for short-term services, and ninety (90) business days in advance for long-term services. In the case of permanent services, if customer terminates the service prematurely - that is, before the conclusion of the agreed term, it shall pay, except where termination results from a failure of the satellite and/or replacement capacity is not available, the following penalties: The amount resulting of the difference between the amount paid and the monthly rate corresponding to one (1) year agreements for each month that the service has been provided; and in addition the customer shall pay in the same date the highest amount that results from: a) Twenty percent (20%) of the total payments unpaid from the date of the termination until the end of the originally agreed term of the respective agreement. If the termination occurs during the second third of the term of the agreement, the percentage will be reduced to fifteen percent (15%). b) The monthly tariff corresponding to one year agreements for each month until the conclusion of the original period of the agreement, not to exceed twelve (12) months. Failure to give notice referred to in the first paragraph of this article will allow SATMEX to continue providing the service in the implied manner, and charge the accounts in full for the ensuing months until customer gives notice of renewal or termination, as the case may be. The cancellation or premature termination of a service does not release the customer from prior debts or late payment fees. SATMEX reserves the right to assign to other customers the released satellite capacity on the next day following the termination date. 38th ARTICLE. Agreements for occasional or periodic services may be terminated in advance when the customer timely gives the termination notice with the following periods: 1. If the service is canceled before ten (10) calendar days prior to the date of the event, no charge will apply. 2. If the service is canceled between ten (10) calendar days and forty-eight (48) hours prior to the event, a charge for the equivalent of sixty percent (60%) of the price of the requested service will be imposed. 3. If the service is canceled forty-eight (48) hours prior to the event, or the service is not used, one hundred percent (100%) of the price of the requested service will apply. CHAPTER IX CAUSES FOR TERMINATION 39th ARTICLE SATMEX may terminate a service agreement in the following events: I. If customer assigns in any way the rights and/or obligation derived of the corresponding agreement to third parties, without the previous written consent by SATMEX. II. If customer fails to pay two (2) consecutive bills for the service provided or three (3) suspensions of said bills in a one (1) year period. III. If customer does not comply with the satellite access parameters indicated by SATMEX. IV. If customer does not provide the guarantee stated in article 20. V. If customer becomes the subject of bankruptcy, insolvency, reorganization or liquidation proceeding or finds itself under any of the conditions found in Article 2 of the Bankruptcy and Reorganization Law. VI. If customer does not accept the relocation that SATMEX should assign. VII. In general, if customer fails to comply with any of the obligations under the respective agreement, or its addenda. 40th ARTICLE. If SATMEX has elements to prove that customer has incurred in any of the causes for termination, it will give written notice to customer to such effect within fifteen (15) business days to allow customer to assert its rights.
