TITLE VIION THE INFRASTRUCTURE SERVICES OFFER

Article No 38 On the Infrastructure Services OfferThe Beneficiary shall provide an Infrastructure Services Offer, which shall be valid throughout the whole Binding Force Period of the Requirements of the Tender Bases. For these purposes, the Proponent shall indicate maximum rates for Infrastructure Services Offer Service provisions, considering the Adjustment Factor in conformity with Annex No.9, as established in Annex No.7 in these Tender Specific Bases.

The Infrastructure Services Offer shall be made effective on each of the POIITs committed in the corresponding Technical Project, in a open and non-discriminatory way, considering, at least, the following:

a. Supplying Submarine Optical Channels and/or Terrestrial Optical Channels in accordance with the type of Optical Infrastructure Trunk the Proponent is applying to, in accordance with Article No 29 in these Tender Specific Bases.

b. Equipment Housing at POIITs.c. Civil Works at POIITs.d. Technical supervision of visits (supervision and maintenance).

Besides, the Beneficiary shall provide, at least, one (1) Customer service office in accordance with Number 1.11 on Annex No.1 in these Tender Specific Bases.

The Proposals shall contain the aforementioned Infrastructure Service Offer in Sobre S4 envelope.

The Beneficiary shall provide the Infrastructure Service under the Infrastructure Service Offer, taking into account that the reference technical unit, for the purposes of commercializing the Infrastructure Service with Customers, is the Submarine Optical Channel and/or the Terrestrial Optical Channel, according to the type of Optical Infrastructure Trunk. In this context, the following shall be borne in mind:

a. In the case of the Southern Submarine Trunk, the Submarine Optical Channels of the Infrastructure Service Offer shall be supplied through the implementation of a DWDM/OTN System, whose frequency grid shall be flexible; that is, one that allows that both the Channel Spacing — which is related to the allocation of Optical Channel central frequencies — and the Bandwidth allocated to the Optical Channels are variable, in accordance to Article 29th and Number 1.1.1.2.1 on Annex No.1 in these Tender Specific Bases.

Yet, one of the characteristics of one (1) Submarine Optical Channel is allowing the two-way transportation of optical signals from different standards such as OTU-k, STM-n and GbE, among others — in accordance to Number 1.1.1.2.1 on Annex No.1 in these Tender Specific

Bases. The above should be implemented by supplying a pair of Optical Channels — one in the direction transmission direction and the other in the receiving direction — to which a certain central frequency and a certain Bandwidth shall be allocated. The pair of Optical Channels shall be hosted in different optical fiber filaments in the submarine cable.

For Commercializing one (1) Submarine Optical Channel, the Beneficiary shall consider that the aggregate Bandwidth of its Optical Channels — one in the transmission direction and the other one in the receiving direction — cannot exceed 100 [GHz]. If the aggregate Bandwidth is below that limit, the full 100 [GHz] Bandwidth per each Submarine Optical Channel shall not be reserved. The remaining Bandwidth may be used to provide Infrastructure Services to another Customer.

The maximum rate committed by the Proponent shall be associated to one (1) Submarine Optical Channel that allows the two-way transportation of OTU-4, using the most efficient modulation scheme that the proposed System supports, also indicating the related aggregate bandwidth, in accordance to Number 7.1 on Annex No.7 in these Tender Specific Bases.

The maximum rate committed will be used as a reference for the calculation of maximum rates associated to Submarine Optical Channels that carry the standards established in Number 1.1.1.2.1 on Annex No.1 in the Tender Specific Bases. Those maximum rates are calculated on a proportional basis in accordance to Number 7.1.1 on Annex No.7 on these Tender Bases.

Likewise, any service provision related to the Infrastructure Service Offer on the Southern Submarine Trunk — such as renting, privately selling or financially leasing the line/tributary cards mentioned on Annex No.7 in these Tender Specific Bases — shall be provided by the Beneficiary in an open and non-discriminatory way.

b. In the case of the Terrestrial Trunks, the Terrestrial Optical Channels of the Infrastructure Service Offer shall be supplied through deploying optical fiber cables lays in accordance to Article 29th and Number 1.2.1.1.1 on Annex No.1 in these Tender Specific Bases.

Yet, one of the features of one (1) Terrestrial Optical Channel is allowing the two-way transportation of optical signals. The Terrestrial Optical Channel shall be implemented through the supply of a pair of optical fiber filaments, one for transmission and the other for reception.

The Beneficiary shall provide the Infrastructure Service under the Infrastructure Service Offer, considering for commercialization purposes that a Customer will be provided up to two (2) Submarine Optical Channels and/or up to two (2) Terrestrial Optical Channels, allowing Customer to access, through each of them, all POIITs committed in the corresponding Optical Infrastructure Trunk.

Yet, the Beneficiary —and the entities that are part of its corporate holding— will be able to have, within the scope of the Infrastructure Service under the Infrastructure Service Offer, up to two (2) Submarine Optical Channels and/or up to two (2) Terrestrial Optical Channels that allow them to access, for each of them, all POIITs committed in the respective Optical Infrastructure Trunk. Exceptionally, the Beneficiary will be able to request SUBTEL, on a well-grounded basis, an increase in the amount of Submarine Optical Channels and/or Terrestrial Optical Channels to be provided per Customer. In this regard, SUBTEL will analyze the grounds of the request and will determine the relevance of this increase in connection to the approval required.

It will be considered that one (1) Customer comprises all the entities being part of the same corporate holding. In this regard, the determination of the quality of the corporate holding will be made pursuant with Law No.18,045 on Security Market and Law No.18,046 on Corporations.

The Beneficiary will be bound with Customers through leasing contracts or any other similar instrument providing rights of use and enjoyment on the physical telecommunications infrastructure, which shall respect the general conditions in that regard stipulated in Number 7.4 on Annex No.7 in these Tender Specific Bases. Likewise, the Beneficiary shall expressly include in those contracts the rights, obligations and prohibitions stated in number 7.3 on Annex No.7 in these Tender Specific Bases. The Beneficiary will not be able to alienate or convey real rights on the Submarine Optical Channels or Terrestrial Optical Channels, and in general on the physical telecommunications infrastructure without prior approval by SUBTEL. Lastly, in order to ensure the compliance with the technical and commercial conditions described in the foregoing clauses, the Beneficiary shall provide SUBTEL a copy of the corresponding contracts, in accordance to Number 10.3 on Annex No.10 in these Tender Specific Bases.

For the purpose of assessing the Southern Submarine Trunk, the Proponent shall commit the maximum rate for one (1) Submarine Optical Channel that allows the two-way transportation of OTU-4 units, using the most efficient modulation scheme that the proposed System supports, also indicating the corresponding aggregate bandwidth, in accordance to number 5.3.1 on Annex No.5 in these Tender Specific Bases. On the other hand, for the purpose of assessing the Terrestrial Trunks, the Proponent shall commit the maximum rate for one (1) Terrestrial Optical Channel, in accordance to Numbers 5.3.2, 5.3.3 and 5.3.4 on Annex No.5 in these Tender Specific Bases.

components and items, which shall be specified in the Detailed Engineering Report required in accordance to Article 32nd in these Tender Specific Bases and number 1.5 on this Annex, before the Infrastructure Service commencement.

Notwithstanding the foregoing, the Beneficiary may freely establish contractual mechanisms, as it deems necessary, to undertake the whole or a portion of the Technical Project awarded and the Detailed Engineering Report accepted and approved, besides fulfilling the requirements contained in these Tender Bases. Furthermore, pursuant to Article 27th in the Tender General Bases, in relation to Article 18th and the second clause of Article 30th in the Tender Specific Bases, the Beneficiary shall be responsible against SUBTEL for the full compliance with the Tender bases, in particular provisioning the Infrastructure Service throughout the whole Binding Force Period of the Requirements in the Tender Bases.

The Proponent shall indicate the main items and criteria used in designing of the technical solution. Likewise, the Proponent shall support and justify, in general terms, the technical solution chosen, the related technology and the route used, among others.

1.1.1.1. System Configuration

The System is comprised by two subsystems called Wet Plant and Dry Plant, which shall be interconnected and integrated. In other words, both subsystems shall properly operate as a whole, besides allowing the interconnection to other telecommunications systems.

According to the technical solution committed by the Proponent, the Wet Plant shall consider the following items: the submarine optical fiber cable, repeaters, the branching units, the power equalizers and any other submersible item allowing the exchange of Submarine Optical Channels in the best way between any two (2) Submarine POIITs, and meeting the technical and performance requirements of the System, specified in numbers 1.1.2 and 1.1.6 on this Annex.

On the other hand, according to the technical solution committed by the Proponent, the Dry Plant shall consider the lading points, the Submarine POIITs, the line terminal equipment, amplifications, power supply plants, Land Cables, supervision and management systems, and any other item allowing the transmission, receipt, monitoring and control over the Submarine Optical Channels carried in the Submarine TRIOTs committed, and that are considered to meet the technical and performance requirements of the System, specified in numbers 1.1.3 and 1.1.6 on this Annex.

The System should be two-way. For this purpose, each optical fiber filament committed shall transmit in simplex or one way mode. 50% of the optical fiber filaments enclosed within the submarine or Land Cable committed shall be intended for transmission, and the remaining 50% shall be intended for reception, in accordance to number 1.1.1.4 on this Annex. The Proponent shall

consider that the submarine optical fiber cable shall enclose, at least, four filaments.

1.1.1.2. Infrastructure Service

The Infrastructure Service to be provided by the Beneficiary of the Southern Submarine Trunk — on an open and non-discriminatory basis during the Binding Force Period of the Requirements of the Tender Bases — considers providing the following services on each Submarine POIIT committed in the corresponding Technical Project awarded: Submarine Optical Channel, Equipment Housing at POIIT, Civil Works at POIIT and technical supervision of visits in compliance with Article 38th and number 7.1 on Annex No.7 in these Tender Specific Bases. Likewise, the Beneficiary shall provide telecommunications infrastructure capacity for Considerations, under the terms required by Article 39th, number 1.1.4 on Annex No.1 and Annex No.8 in these Tender Specific Bases.

For the Infrastructure Service provision subject matter of this Tender, the Proponent shall design a System meeting the requirements established in numbers 1.1.2. 1.1.3, 1.1.6 and 1.1.7 on this Annex. Likewise, such Infrastructure Service does not comprise the interconnection between the Southern Submarine Trunk and the existing telecommunications networks — operated by third parties — or the interconnection to the Terrestrial Trunks awarded, except for the requirements on number 8.2.3 on Annex No.8 in the Tender Specific Bases, notwithstanding the commercial agreements both parties may enter into on this regard. Those agreements shall comply with the requirements stated in numbers 7.3 and 7.4 on Annex No.7 in these Tender Specific Bases.

In the Technical Project, the Proponent shall account for the way in which the technical solution allows the Infrastructure Service provision subject matter of this Tender. The Proponent shall describe in detail the technical conditions and requirements related to each of the services considered in the Infrastructure Service Offer established in number 7.1 of Annex No.7 in the Tender Specific Bases. Furthermore, the Technical Project shall contain a list describing and quantifying all the equipment, components and items committed that comprise the subsystems of the Southern Submarine Trunk, considering their operation for the amount of Submarine Optical Channels committed by the Proponent. That list should be strictly consistent to what is shown on virtue of the requirement on letter f) on Annex No.2 in these Tender Specific Bases.

1.1.1.2.1. Submarine Optical Channels

For the supplying the amount of Submarine Optical Channels required in accordance with Article 29th of the Tender Specific Bases, the Proponent shall consider deploying a submarine cable enclosing a number of optical fiber filaments equal to or greater than four (4) filaments in accordance to the last paragraph of number 1.1.1.1 on this Annex. In case deploying a submarine

cable is considered, or using optical telecommunications infrastructure the Proponent already owns, previously approved by SUBTEL, containing a higher amount of optical fiber filaments than the amount required, is considered, the Proponent shall expressly state on the Technical Project the total amount of optical fiber filaments enclosed within the cable committed, identifying the amount of filaments that will be used for providing the Submarine Optical Channels committed in its Proposal. Likewise, the Proponent shall declare the service provisions to be offered through the remaining filaments enclosed within the optical fiber cable committed, taking into account the stipulations in Article 40th and number 1.10 on this Annex, both in the Tender Specific Bases.

On the other hand, in order to implement Submarine Optical Channels provision, the Proponent shall design a DWDM/OTN System, whose frequency grid shall be flexible, pursuant to ITU-T G.694.1 recommendation — that is, the frequency that allow both Channel Spacing and Bandwidth related to Submarine Optical Channels to be variable. The Proponent shall expressly declare Bandwidth granularity and central frequency granularity, expressed in [GHz], on the Technical Project, justifying them with the corresponding technical factors. It should be noted that the Channel Spacing may be any multiplier of the corresponding granularity declared by the Proponent, notwithstanding that the technical and commercial conditions for the Submarine Optical Channels established on Article 38th in these Tender Specific Bases shall be taken into consideration.

Similarly, if the implementation of Guard Bands in the System is required to ensure the proper operation of the Infrastructure Service subject matter of this Tender, the Proponent shall take into consideration that the Bandwidth of those Guard Bands shall be efficient in terms of the use of the Optical Spectrum available in the System. In this regard, the Technical Project shall show that such available Optical Spectrum is sufficient for providing the amount of Submarine Optical Channels to be committed pursuant to Article 29th in the Tender Specific Bases and from the corresponding Guard Bands.

One of the features of a Submarine Optical Channel is that it allows two-way transportation of different types of optical or tributary signals, according the requirements by the Customer. Such Submarine Optical Channel shall be implemented by supplying a pair of Optical Channels — one in the transmission direction and the other in the receiving direction — each of them characterized by a certain central frequency and a certain bandwidth. The pair of Optical Channels shall be hosted in different optical fiber filaments within the submarine cable committed. Likewise, those Optical Channels shall be symmetrical; that is, the amount of information carried in transmission direction shall be the same as the amount of information carried in the receiving direction. The Proponent shall describe the way the proposed System allows the provision of Submarine Optical Channels, considering the items that will comprise the SLTE, in accordance with the specifications in number 1.1.3.5 of this Annex; also indicating the way in which those items will interact for this service provision purposes.

In regard to optical or tributary signals that may be carried by using the Submarine Optical Channels of the Infrastructure Service Offer established in number 7.1 of Annex No.7 in these Tender Specific Bases, it should be noted that those signals may be any OTU-k hierarchy (OTU-1, OTU-2, OTU-3, OTU-4 and OTUCn), synchronous speed STM-n hierarchies (STM-16, STM-64 and STM-256), and hierarchies from the 10GbE, 40GbE and 100GbE standards, among others. In this regard, the Customers of the Infrastructure Service subject matter of this Tender may require standards other than the aforementioned standards, provided these standards are supported by the System implemented and the transportation capacity required by the Customer is not lower than the capacity related to OTU-1.

On the other hand, the Customers may choose the modulation scheme to be used in the Submarine Optical Channel provision from the modulation scheme set supported by the System committed, taking into consideration that such election shall allow the proper operation of the Infrastructure Service subject matter of this Tender.

For commercializing one (1) Submarine Optical Channel, the Beneficiary shall consider that the aggregate Bandwidth of its Optical Channels — one in the transmission direction and the other in the receiving direction — cannot exceed 100 [GHz]. On the other hand, If the aforementioned aggregate Bandwidth is lower than the aforementioned limit, the Beneficiary shall not reserve the total 100 [GHz] Bandwidth per each Submarine Optical Channel. In this regard, it is worth noting that the Bandwidth of each Optical Channel comprising the Submarine Optical Channel will be determined based on the requirements of the Customer for the Submarine Optical Channel; that is, considering the type of optical or tributary signal to be carried in the transmission direction and in the receiving direction, and the modulation scheme chosen by the Customer from those the Beneficiary declares are supported by the System proposed.

The Proponent shall consider that the level of mechanical protection for the cable that will be used in the repair shall be the same as the level of mechanical protection for the cable originally installed.

In this regard, the Technical Project shall indicate whether the Proponent will use adjustable equalizations, which types will be implemented (justifying its choice, taking into consideration the compliance with the requirements in these Tender Specific Bases) and the System design proposed.

The Technical Project shall consider that traceability of these components shall comply with ISO-9001 Standard.


The Technical Project shall indicate the main electric, mechanic and optical features, and justify their choice on the design criteria which makes them appropriate for the System. Furthermore, in the Detailed Engineering Report, the Beneficiary should provide the dimension and weight specifications, in addition to a block diagram on the operation of this item, and as part of the System. The Beneficiary shall also indicate the installation features or procedures.

For adjustable equalizers only, it shall be considered that the optical equalizer will be fed from the Submarine POIIT at a constant current through the electrical wire within the cable, and it shall accept both electric polarities. The power supply modules shall feed the adjustable equalization modules to obtain the optical amplification profile required.

The optical equalizers shall implement protection mechanisms against over voltage that may result from sudden high voltage power supply in the cable (interruption of the cable, failure due to branching or short circuit in the PFE).

Taking into consideration that ITU-T G.977 recommendation states that the equalization modules perform an optical filtering function in the Optical Spectrum in order to equalize the residual gain/wavelength and/or gain variation ripple accumulated when the optical signal is transmitted through a number of submarine optical repeaters, the Proponent may consider in the Technical Project that it will be possible to add adjustable functions to the optical equalizers in order to adjust the filtering function response of the equalization module.

For that, the Beneficiary shall inform SUBTEL on the new maximum rates, along with annual indexation formula suitable to the operation of the license, developed from the information retrieved from the Financial Project and attaching a study supporting such rates and the annual indexation formula. This study shall be comprised by a hard-copy document and the corresponding digital media — containing, at least, the background information, calculation Reports and all the information supporting the maximum rate and the annual indexation formula proposed. The annual indexation formula shall consider the annual accumulated PPI and the new annual Adjustment Factor related to the technical solution deployed.

SUBTEL will have twenty (20) business days in order to Report back the Beneficiary on whether it accepts or rejects the new maximum rates, along with the new annual indexation formula.

In case SUBTEL accepts the new maximum rates, along with the annual indexation formula, they will be valid for the next eight (8) years of operation of the Infrastructure Service, decision that will be notified to the Beneficiary.

After the period in the paragraph above, SUBTEL will perform a new review process on the Infrastructure Service maximum rate, according to the procedure described in this bullet point.

In case the beneficiary fails to Report, it Reports out of term, or SUBTEL rejects the new maximum rates, along with the new annual indexation formula proposed by the Beneficiary, the procedure applied will be the one described in the following bullet point.

9.2.2. Infrastructure Service maximum rate review process using the model company methodology.

In case the beneficiary fails to Report, it Reports out of term, or SUBTEL rejects the new maximum rates, along with the new annual indexation formula proposed by the Beneficiary, SUBTEL will perform a review on the Infrastructure Service Maximum rates and the corresponding annual indexation formula taking into account an Adjustment Factor associated to the operational efficiency, using the model company methodology.

For this purposes, the company modeled for reviewing the maximum rates and the annual indexation formula will be for the sole purpose of providing intermediate telecommunications services solely providing physical telecommunications infrastructure. The modeling process will consider the necessary investments in order to provide such service, as well as the operational costs, lifespan of assets, residual values, tax rates and capital costs. On top of that, the subsidy awarded will be considered.

SUBTEL will notify the Beneficiary on the Infrastructure Service maximum rate and the annual indexation formula review process starting.

SUBTEL will notify the Beneficiary on the new maximum rates and the new annual indexation formula within one hundred (100) calendar days from the notification of the start of such review process. Such maximum rates and the new annual indexation formula will be notified detailing the items used for developing the new maximum rates and the new annual indexation formula.

Within thirty (30) calendar days, the Beneficiary shall inform SUBTEL, with grounds, on the acceptance or rejection of the new maximum rates and the new annual indexation formula developed by SUBTEL.

If the Beneficiary fails to inform, informs out of time, or accept the maximum rates and the annual indexation formula proposed by SUBTEL, they will be valid during the next four (4) years of operation of the Infrastructure Service.

On the contrary, if the Beneficiary rejects, with grounds, the new maximum rates, along with the new indexation formula proposed by SUBTEL, they will be determined by a commission comprised of three (3) appointed experts, one by the Beneficiary, the second one by SUBTEL, and the third one upon agreement between the parties. Likewise, these experts will be paid according to what SUBTEL and the Beneficiary determine.

The experts commission shall determine the new maximum rates and the new indexation formula for the Infrastructure Service, developing a Final Report on the Maximum Rate Update Procedure for the Infrastructure Service, which shall consider, at least, the modeling process developed for these purposes by SUBTEL. Such Report shall be submitted by the Commission within sixty (60) calendar days from its conformation. The new maximum rates and the new annual indexation formula for the Infrastructure Service will be valid during the next four (4) years of operation of the Infrastructure Service.

After the period in the paragraph above, SUBTEL will perform a new review process on the Infrastructure Service maximum rates, according to the procedure described in number 9.2.1 on this Annex.

SUBTEL may modify the terms and milestones stated in previous bullet points if deemed suitable, situation that will be promptly disclosed to the Beneficiary.

Notwithstanding the foregoing, the Beneficiary shall be subject to the regulation in force for these matters.
