PURPOSE

4.1

Exclusivity and Responsibility

As a consequence of the award made in the present National and International Public Bidding Competition, the Concession Grantor grants and the Concession Holder accepts the present concession for the operation, management and functioning of Airport Group A, on an exclusive basis, in accordance with the terms of the present Concession Contract and the provisions of section 3.5 of the Bidding Conditions and the regulations interpreting and supplementing the same.

To this end, the Concession Grantor, prior to the calling of the bidding competition, issued instructions to the pertinent dependencies of the national government to the effect that no new concessions were to be granted and/or existing concessions extended at the airports included in Airport Group A. Where necessary in order to ensure the continuity of services, the authorities were to resort to the mechanism of temporary permits for the providing of such services, Consequently, the granting of such temporary permits does not involve conferring any right upon the recipients of the same. The Concession Grantor guarantees the Concession Holder that the aforementioned permits shall not serve to enable the holders to contest the rights of the Concession Holder, the latter likewise being guaranteed the full use and enjoyment of the Concession on terms similar to those which would have existed if such permits had not been granted.

The Concession Grantor shall not authorize any alteration of airport infrastructure in the areas of influence of the National Airport System member airports in accordance with article 12 and article 17, section 34 of Executive Order No. 375/97, except pursuant to the terms of the Contract.

The concession is granted on a basis of Exclusivity, and the Concession Grantor shall under no circumstances have the right to lay aside this exclusivity clause and thereby affect the economic and financial equation of the Contract.

Under no circumstances shall the Concession Grantor be held responsible for the operation, management and functioning as to which a concession is granted under the present contract, or for maintenance and expansion of Airport Group A.

4.2

Scope

The Concession granted means that the Concession Holder shall assume exclusively the obligation of meeting any increase in demand within Airport Group A, subject to the quality specifications of ICAO/IATA, as specified under Exhibit 4 accompanying the present Contract, as well the obligation of making the investments provided for under Exhibit 3 accompanying the present Contract.

Any airport infrastructure work not duly approved by ORSNA shall be required to be demolished, in such manner as to leave the airport surface clean and vacant, unless an agreement is reached with the Concession Grantor whereby the latter accepts the same, with no right on the Concession Holder’s part to any charge or compensation.

For all work, including demolition, authorization must be requested from ORSNA and the work must proceed in accordance with such instructions as the latter may issue, within the scope of the Concession Holder’s obligations deriving from the present Contract. Such demolition may come about on the initiative of the Concession Holder, the Argentine Air Force or ORSNA, but in all cases approval must be obtained in advance from ORSNA in order to carry out the work.

The Concession granted is at the Concession Holder’s sole risk. Likewise, the Concession Grantor assumes no responsibility of any kind for the Investment Plan for which the Concession Holder is responsible.

4.3

Additions and Decommissioning

Subject to the Concession Holder’s approval, ORSNA shall have the right to withdraw from Airport Group A any airports that may have fallen into disuse as a result of changes in market conditions. In due time, ORSNA shall establish methods of analysis such as to permit defining under what circumstances an airport shall be deemed to have fallen into disuse.

In such cases, ORSNA shall take into account the impact of airport service on the region concerned.

Likewise, Airport Group A shall include any airports that may come to be incorporated into the same by decision of ORSNA, subject to the Concession Holder’s approval.

4.4

Replacement of an Airport

During the Concession Period, the Concession Holder shall be permitted to propose for approval by ORSNA the replacement of one or more airports by constructing new airports. In such cases, the airports to be replaced must be returned and turned over to the Concession Grantor simultaneously with the placing in service of the new airport(s). The Concession Holder shall be required to demonstrate to ORSNA the resulting benefit to Users, in terms of price and quality of service.

In all cases in which airports are replaced, authorization must be obtained in advance from ORSNA or the authority having competent jurisdiction under applicable legislation. The basic criteria that will be taken into account by ORSNA for purpose of such authorizations are as appears from the Bidding Conditions, without prejudice to attention to such national airport policy considerations as may be established by the national government, as well as the rights acquired by the Concession Holder by virtue of the Concession Contract and applicable provisions of law. ORSNA may consider alternative solutions proposed by the Concession Holder, or proposed by ORSNA with the Concession Holder’s approval; in all cases, however, final approval shall require an express decision on the part of the latter body.

Likewise, in all cases involving replacement of airports, it shall be the responsibility of the Concession Holder to arrange for all approvals and/or authorizations relating to locations and sites for the new airports, by ORSNA and the appropriate authorities. Any delay in obtaining the pertinent authorizations shall not be regarded as constituting grounds for postponements in the construction schedule for the new airports, unless the Concession Holder demonstrates to the satisfaction of ORSNA that the cause of such delay is not imputable either to the Concession Holder itself or to any interposed third party for which the Concession Holder is responsible.

Infrastructure and equipment quality standards must tend to improve upon those currently offered by the airports to be replaced, and in no case shall be inferior thereto.

In order to do so, ORSNA shall be required to give valid notice of such demand to the Concession Holder at least six months in advance of expiration of the Concession Period.

If the Concession is extended, the Concession Grantor shall consider the effect of such extension on the economic and financial equation of the Concession, taking into account for this purpose the fact that the recovery of investments should have taken place during the original term of the Concession.

6.1

Transmittal

The Concession Grantor tenders or assigns – as appropriate – the property to the Concession Holder on the following terms:

Real Property

6.3.1

Transfer of Use

The award involves the granting to the Concession Holder of custody of the real property located within the perimeter of each airport, as identified on the record to be drawn up at the time of the pertinent Taking of Possession.

The granting of custody of property as alluded to under the preceding paragraph includes, in addition to use, the safekeeping and upkeep of the property, without prejudice to such wear accused to the same merely by the passing of time and proper use of the same, provided, however, that nothing herein shall operate to vitiate any maintenance or other obligations assumed by the Concession Holder in accordance with the present Contract and the rest of the bidding documentation. Notwithstanding the foregoing, ORSNA shall be required to respect the provisions of the Concession Contract and the rest of the bidding documentation, its authorization being required for any activities not expressly provided for therein, as well those which, being provided for, are subject to the requirement that such authorization be obtained.

6.3.2

Assignment of Use

The Concession Holder shall have the right to assign, for consideration or otherwise, the use of part of the real property made available for the Concession Holder’s use under the present Contract. In this regard, the Concession Holder shall have the right to enter into rental, commodatum [gratuitous bailment] or other similar contracts concerning the real property received. All assignments made by the Concession Holder must be reported in advance by the latter to ORSNA, which shall have the power to contest the same when the consideration for the assignment is lacking or unrealistically low, and the assignment is not warranted from the standpoint of the management, operation or functioning of the airports.

6.3.3

Obligations

The Concession Holder shall be required to use the real property mainly for providing airport service on the terms authorized by ORSNA as to the activities involved. Use of the property must be such as fully to meet airport service needs. The property may also be used at the same time for other activities relating to airport activity, subject to the proviso that the designated purpose of the present Concession Contract shall not be affected as a result.

As to real property received from the Concession Grantor by commodatum, the Concession Holder must pay all taxes, official charges and utility service charges payable by the Concession Holder in its capacity as such, and accruing after the Taking of Possession, without prejudice to its fulfillment of all of the other obligations inherent in commodatum.

The obligation mentioned in the preceding paragraph does not include real property tax, payment of any such tax due being the responsibility of the property owner.

6.3.4

Destruction of Property

In the event that for any reason, any property is destroyed in whole or in part, regardless of whether such destruction is caused by the Concession Holder itself, its employees or contractors, or third parties, the resulting damages shall be borne and repaired entirely by the Concession Holder, with the exception of those cases in which the latter can validly assert the defense of an act of God or force majeure, and in no case shall the latter have the right to demand of the Concession Grantor or ORSNA that the same be replaced or repaired, or to assert against either a claim for indemnity or compensation of any kind for the damages caused. Without prejudice to the foregoing, the Concession Holder shall be required to take out insurance covering risks to the extent established in the aforementioned [sic] point 17.

The limitation stated above shall not bar the bringing of actions for compensation of damages or actions of any other kind which the Concession Holder may deem appropriate against the parties that caused or are responsible for the aforementioned damages, whether public or private, governmental or nongovernmental.

The Concession Holder shall not be required to replace or repair any property that proves unnecessary to the proper fulfillment of the obligations assumed by the Concession Holder, or proves to be superfluous, obsolete or redundant.

In none of the aforementioned cases, with the aforementioned exception of acts of God or force majeure, shall Concession Holder be excused from replacing or repairing the property destroyed in whole or in part, without prejudice to any actions for compensation of damages or actions of any other kind which the Concession Holder may deem it appropriate to bring against the parties which caused or are responsible for these damages.

Inasmuch as the Awardee formulated its bid based on its own evaluation and research, likewise receiving the property “as is,” all of the foregoing with no right to any claim of any kind, any assertion on its part of a warranty against hidden defects shall be under stood to be precluded.

6.3.5

Legal Impossibility of Continuing Use of Property

When any circumstances now in existence or coming to exist in the future makes legally impossible the continued use of any given property by the Concession Holder, the latter shall be required to return such property to the Concession Grantor.

In such event, the Concession Grantor shall not be liable for any damages that may be caused to the Concession Holder.

When loss of the use of property substantially affects the economic and financial equation of the Concession, the Concession Grantor shall be required to replace the property concerned with other similar property, or, alternatively, to adjust the economic and financial equation of the Contract to allow for the new circumstances, to the extent of the proven effect of the same.

The circumstances giving rise to the legal impossibility of continued use of the property by the Concession Holder must be beyond the Concession Grantor’s control, or must be the result of acts grounded on considerations of public interest or force majeure.

If assets appointed to airport activity under the terms indicated in the Contract are determined during the Taking of Possession to be missing or destroyed, and such assets are not essential, their absence or destruction shall not operate to bar the obligation to take possession or to give rise to a claim of any kind. Assets are to be regarded as nonessential if the absence or insufficiency thereof does not impede the continued operation of the airport on the same terms as up to the moment of the Taking of Possession of the same, or, in the case of those whose absence or insufficiency does represent an impediment, if the providing, creation or improvement of the same is the responsibility of the Concession Holder.

All property found within Airport Group A at the time of termination of the Concession Contract, whatever the reason for its presence, shall be presumed as of that time (except if proven otherwise by the Concession Holder) to be the property of the Concession Grantor, and shall be required to be transferred to the latter without charge, in accordance with the terms indicated under the Concession Contract.

While the Concession Holder cannot transfer a better right than it received from the Concession Grantor, the Concession Holder shall be responsible for taking precautions to see that the provisions of the present subsection are respected and enforced under any contracts it may enter into with third parties.

6.3.6

Relations with the Argentine Air Force

The Concession Holder shall grant free of charge to the Argentine Air Force, at each airport, the spaces necessary for purposes of the carrying out of the latter’s specifically assigned functions.

Likewise, for purposes of carrying out its functions, the Argentine Air Force shall have freedom of access and movement within airport facilities for which the Concession Holder is responsible, subject to notice to the personnel designated for such purpose.

Inasmuch as the specific functions of the Argentine Air Force include, in addition to those listed in the bidding documentation, the functions established under the laws of Argentina, including national defense, the Concession Holder shall be required to be governed at all times by the consequences of such laws and the regulatory provisions deriving therefrom.

CORPORATE STRUCTURE

7.2

Restrictions

The shares of the corporation entering into the present Contract as a Party shall not be pledged or encumbered without authorization in advance from ORSNA.

The Concession Holder’s shareholders of record shall not be permitted to change their holdings or sell their shares during the first five years following the Effective Date. Thereafter, they shall not be permitted to change their holdings or sell shares without prior approval from ORSNA.

INVESTMENT PLAN

10.1

Fulfillment

It is the exclusive responsibility of the Concession Holder to make the investments offered in the pertinent National and International Bidding Competition, on the schedule likewise offered, as appended to the present Contract as Exhibit 3.

The investments to be made must in all cases be designed to cover increased demand and associated needs within Airport Group A, as well as to meet the minimum standards specified by ICAO and IATA.

The investment commitments for each airport, as included in the Investment Plan, may be modified, provided:

The modifications are included in the duly approved Master Plan.

The total amount for each year does not change.

The commitments assumed by the national government under the agreements signed with provincial and/or municipal governments for the assignment of the use of the airports included in the Concession are not affected.

Likewise, the Investment Plan must provide for replacement of the ▇▇▇▇▇ ▇▇▇▇▇▇▇ airport in the city of Buenos Aires prior to year 7 of the Concession, by means of either a new or an existing airport capable of meeting the airport demand needs of the city of Buenos Aires over the term of the Concession, whether by absorbing such demand at an existing airport or proposing a new one. In the latter case, only investments of a strictly airport- related nature shall be taken into consideration, and not those of a supplementary nature, which must be proposed at the time of evaluation of the preliminary project design for the site concerned.

The Concession Holder shall not be obligated to fulfill the Investment in Increased Capacity requirements at the airport to be replaced, provided the dates scheduled for construction of the new airport are respected. In such event, it shall be under stood that the Investment in Increased Capacity so omitted shall become part of the investment to be made in the new airport. Meanwhile, the replacement of the ▇▇▇▇▇ ▇▇▇▇▇▇▇ airport must cover and adequately meet the demands of present and anticipated future airport service to and from that airport.

This situation shall be governed by all of the provisions of section 3.17 of the Bidding Conditions, and by the provisions of section 4.4 of the present Contract.

With the express approval of ORSNA, the Concession Holder may postpone part of the investments scheduled for a given year, but in such case it shall be required to make a bank deposit in the amount originally committed to the investment so postponed, in accordance with such instructions as may be imparted to the Concession Holder by ORSNA to this end. Interest earned on such deposit shall be regarded as an increase in the royalty and credited accordingly to the Concession Grantor. The provisions of the present paragraph shall not be deemed to constitute a change in the provisions relating to the performance guarantee covering the commitments assumed under the Investment Plan, but the fines prescribed for delays in the schedule contemplated under the Investment Plan shall not apply as to those investments whose postponement has been authorized, for the duration of such postponement.

In order to evaluate the Concession Holder’s fulfillment of investment commitments during the first three one-year periods, and taking into consideration the fact that the Concession Holder has up to 360 days to complete the Taking of Possession of all of the Group A airports, the Concession Holder shall be deemed to be fulfilling investment requirements provided it has invested, as of the end of such three periods running from the Effective Date of the Concession Contract all of the sums contemplated for the three periods, in the manner explained in the preceding paragraph.

Investments scheduled for 1997 are to be regarded as pertaining to the first period beginning with the Effective Date of the Concession Contract, Investments scheduled for 1998 shall pertain to the second period, and so on. To this end, each period shall be regarded as consisting of one calendar year. The Tucumán and Viedma airports shall not become part of Airport Group A until the end of the first period; for this reason, the investment calendar for these airports shall begin to run with the second one-year period of the Concession.

10.2

Guarantees

In order to guarantee the faithful fulfillment of the Investment Plan included in Exhibit 3 accompanying the present Contract, the Concession Holder submits hereupon a guarantee for the first five years of the Concession Period, on the terms established under the Bidding Conditions, for renewable periods of 30 months, in the amount of 10% of the investment amount for the period concerned.

Between years 5 and 10 of the Concession, the investment percentage to be guaranteed may be reduced by half, subject to approval in advance from ORSNA. Thereafter, ORSNA shall set the percentage to be guaranteed. In all cases, ORSNA shall base its decision on the degree of fulfillment of the Concession Holder’s obligations.

Any renewal of this guarantee must include both the amount of the investments remaining to be made for the then current one-year period, and the amount of the investments scheduled for the next 30 months covered by such [renewal of the] guarantee.

11.

MASTER PLAN

The Concession Holder shall be required to prepare a Master Plan for each of the airports included in Airport Group A, in accordance with ICAO/IATA specifications.

Such Master Plan shall be submitted for approval by ORSNA within 24 months of the Effective Date, and shall reflect the investments to be received by each of the airports. The Master Plan shall in no case be permitted to reduce the total investment amount to which the Concession Holder is committed under its Investment Plan.

Once approved by ORSNA, the Master Plan for each airport may be amended only with approval in advance from ORSNA.

Master Plans shall be submitted for the term of the Concession Contract, and shall be adjusted by the Concession Holder when the following contingencies arise:

At airports with traffic exceeding 500,000 passengers per year, the Master Plan shall be updated at ten-year intervals, unless the airports concerned experience a difference on the order of 20% between actual passenger volume and that originally projected under the pertinent Master Plan.

At airports with traffic of less than 500,000 passengers per year, the Master Plan need not be updated unless the airports concerned experience a traffic volume differing by more than 50,000 passengers from that projected at the time of preparation of the pertinent Master Plan.

ROYALTY

The Concession Holder shall be required to pay the Concession Grantor, by way of an annual royalty, the amount resulting from combining the basic royalty, adjustments, updates and arrangements hereinafter provided for.

17.1

Amount

(a)

The annual royalty amount offered by the Awardee in its final financial bid, hereinafter the “basic royalty,” namely $171,121,000, payable by the Concession Holder one-half at the end of each six-month period, in U.S. dollars.

(b)

To this end, the payment dates are hereby established as being no later than 30 days after the end of each calendar half-year; that is, June 30 and December 31 of each year.

(c)

In order to determine the amount payable by way of basic royalty at the end of the first half-year of the Concession, as well as for purposes of the updating provided for, the reference date shall be deemed to be the date of the taking of possession of all Group A airports, or the date on which a period of 180 days elapses following the Taking of Possession, whichever is earlier.

(d)

In the event that the end of the first calendar half-year following the reference date does not coincide with the elapsing of a full six months [of the Concession], the amount payable by way of basic royalty on such date as provided for under (b) above shall be prorated for the time elapsed since the reference date. The same principle shall apply, where appropriate, to the determination of the amount of the last basic royalty payment at the end of the Concession, counting the time elapsed from the closing date of the six-month period immediately preceding.

(e)

The criterion applied for purposes of updating the basic royalty shall be the change in the Producer Price Index for Finished Goods, Seasonally Adjusted – Total (PPI), published monthly by the Bureau of Labor Statistics of the United States Department of Labor, between the month of December of the year in which the reference date referred to under (c) above falls (the same being regarded as the “PPI base year “), and December of the year for which the update adjustment is to be calculated. Such update adjustment shall be applicable beginning with the year following that taken as the base year, until the end of the Concession.

(f)

Beginning with the sixth calendar year, counting from the reference date, changes in air traffic at Airport Group A, measured in Total Transportation Units (UTG), shall be incorporated into the update adjustment provided for under the preceding subsection. For purposes of this provision, the fifth calendar year shall be regarded as the “UTG base year.”

(g)

The following algebraic expressions shall be used to determine the update adjustments provided for under (e) and (f) above:

Through the fifth calendar year:

I_i = ((P_i/ P₀) – 1) x 100

Beginning with the sixth calendar year:

I_i= (((P_i’ / P₀) x (T_i’/ T₀)) – 1) x 100

Where:

I_i	=	Update adjustment percentage for year i, where i = year 2, 3, 4 or 5.

I_i’	=	Update adjustment percentage for year i’, where i’ = year 6, 7, . . 30).

P_n	=	PPI for December of the year subject to update adjustment.

P₀	=	PPI for December of the “PPI base year.”

T_i	=	Total Traffic Units (UTG) for the year subject to update adjustment.

T₀	=	Total Traffic Units (UTG) for “UTG base year.”

(h)

The amount resulting from the above update adjustment calculations shall be paid in a single yearly payment to be made within 90 days of the end of the calendar year subject to update adjustment.

17.2

Environmental Expenses

If the Concession Holder incurs expenses as a consequence of correction of the effects of environmental situations already in existence as of the time of the Taking of Possession or any reconstruction deriving therefrom, any such expenses approved or authorized by ORSNA shall be deducted from the next royalty payment.

The Concession Holder shall not be obligated to question the validity, legality, constitutionality or applicability of any tax provisions the competent authorities may seek to impose on the Concession Holder following the Taking of Possession, in order to be entitled to pass on the tax burden as provided for under the preceding subsection. Once the provisions making the change in the total tax burden have been enacted, the Concession Holder shall have the right to apply to ORSNA for the passing on of the same whenever regulated rates become affected, and ORSNA shall be required to grant the relief so applied for, once the impact of the Change on the Concession Holder’s economic and financial equation has been verified.

When the cumulative amount of fines imposed on the Concession Holder comes to exceed 20% of the latter’s gross revenues, net of taxes and official charges for the 12-month period concerned. This calculation and determination shall be made by ORSNA following the close of each one-year period.

In order for fines to be counted, the same must at least have been affirmed by final administrative ruling. Likewise, the gross revenues considered as mentioned above shall be those for the one-year period immediately preceding the date of calculation.

(c)

If the shareholders encumber or allow to be encumbered in any manner the shares of the Concession Holder without ORSNA’s participation, and do not proceed to secure the discharge of such encumbrance within such time limit as may be specified by ORSNA.

(d)

If a meeting of Shareholders of the Concession Holder approves, without ORSNA’s participation, an amendment to the Bylaws of the Corporation or a share issue that alters or permits alterations in the shareholdings existing at the time of incorporation, on the terms established under the Bidding Conditions.

(e)

If shares in the Concession Holder are transferred in violation of the provisions of the Bidding Conditions or without prior approval from ORSNA.

(f)

Failure to make payment of the royalty on time and in the prescribed form, in accordance with the Concession Holder’s obligation.

In the event of any of the breaches of duty mentioned in the present article, ORSNA shall have the right to notify the Concession Holder that the latter must regularize the situation, on pain of rescission of the present Contract.

If the Concession Grantor makes use of the power granted by the present subsection, it shall pay the Concession Holder the updated value of the aviation investments made that have not been amortized as of the time dissolution is ordered, deducting from the same the following percentages by way of compensation for damages incurred by the Concession Grantor:

During the first ten years of the Concession, 50%.

During the second ten-year period of the Concession, 45%.

During the third ten-year period of the Concession, 40%.

Aviation investments shall be regarded as consisting of those deriving from the provisions of the present Contract or having been authorized by ORSNA as aviation investments, which are made by the Concession Holder on airport premises.

For purposes of the present section, the investments considered shall not include those not originally contemplated under the Investment Plan or not expressly authorized by ORSNA.

Without prejudice to the foregoing provisions, in the event of rescission of the Contract because of a breach of duty on the part of the Concession Holder, the Concession Grantor and ORSNA shall foreclose the guarantees posted to cover performance of the Contract and fulfillment of the Investment Plan.

23.2

Breach of Duty on the Part of the Concession Grantor

When the Concession Grantor comes into breach of its obligations in such manner as to prevent the Concession Holder from providing the service called for by the present Contract, or seriously affect the same in a permanent manner, the Concession Holder shall have the right to demand rescission of the Contract, following notice to the Concession Grantor to remedy the situation within 90 days.

Airport Standards / Quality of Service

Listing of National Airport System Group A Airports

EXHIBIT 1 – RATE MECHANISM

The National Airport System Regulatory Body (ORSNA), in order to regulate National Airport System (SNA) aviation charges, shall apply the mechanism described in detail as follows:

The adjustment of rates shall be based on the formula PPI-X, where:

PPI means the Producer Price Index published monthly by the Bureau of Labor Statistics of the United States Department of Labor.

X represents an adjustment factor which is set by ORSNA in accordance with the guidelines set forth in the present Exhibit.

Without prejudice to the figures established for the Initial Rate Schedule, the applicable aviation charges shall be reviewed by ORSNA every three to five years, as the latter may deem appropriate. At the time of each rate review, ORSNA shall set the value for the adjustment factor X, which may have point values for each year or for a given period of time.

Adjustment Factor X

In calculating adjustment factor X, ORSNA shall take into account five basic variables, as follows:

Increase in Traffic

Must be in such form as to be able to be converted into a projection of aviation revenues. This means that traffic projections must be expressed in terms of domestic and international passengers and aircraft movements, and the latter must likewise be broken down by aircraft type and maximum take-off weight, a fundamental factor in determining several aviation charges.

Improvements in Efficiency

In response to the advantages resulting from the developing of economies of scale, ORSNA shall estimate the extent of airport management cost savings benefits, or, alternatively, set reasonable cost reduction goals for each successive period of three to five years.

Level of Services

ORSNA shall have the right to impose certain service quality levels for different groups of airports, depending on their size (passenger and air craft traffic volume), characteristics (size of terminal, runways and operations area). The fundamental objective is to ensure that the airport operator does not generate profits by reducing the quality of service.

Levels of service are to be determined by ORSNA based on studies carried out by the latter or subcontracted to specialist consultants, who shall prepare a thorough analysis of the needs of users (airlines and passengers). The methods to be used include the Service Quality Index, which is calibrated by means of a questionnaire circulated to users.

Projected Investment Levels

Once the Project Master Plans have been approved by ORSNA, the total investment value for the next five-year period shall be determined.

Projected Rate of Return

The objective rate of return considered acceptable by ORSNA, as well as by the operator(s) of the airport(s). This rate must be in proportion to the rates of return achieved in other generally similar service industries in Argentina. It must also include a risk premium in view of the uncertainty associated with managing a large number of small, relatively unprofitable airports.

The rate of return to be used is the return on principal. This is adjusted operating income (operating revenues less costs less amortization) expressed as a percentage of principal.

The diagram below shows the relationship among the various variables and the information necessary for determining the adjustment coefficient X.

Value of Concession Holder’s Assets or Investment

The figure used as the value of the Concession Holder’s assets shall be that actually paid by the Concession Holder. This represents the investment that will be used by the new owner or concession holder of the airport to determine the concession holder’s future return value.

By way of updating the future value of the assets, the value of the same is adjusted every three to five years, in order to reflect new investments and inflation. The net investment consists of investment disbursements less the proceeds from sales of assets, if any The CPI for the construction industry [is used] to increase the value of the assets.

Determination of Prices of Network or Multiple Services

Airports and airfields are divided into five different categories for rate setting purposes. The rate structure is applicable to all categories, but the level of the charges may vary for any or all of the categories. ORSNA, taking into consideration cost structures, levels and composition of traffic for each of the airport groups, is to set rate levels for each specific category.

The airports are listed below by category.

Please see section 6 of the Final Memorandum of Agreement included as exhibit 10.2

EXHIBIT 4 – AIRPORT STANDARDS / QUALITY OF SERVICE

Airport Standards

With regard to design, construction, operation, management, maintenance, renovation, replacement, improvements, development of buildings, equipment, facilities and systems involved in airport activity, the applicable standards shall be those prudently and reasonably established by the National Airport System Regulatory Body (ORSNA), in accordance with the following guidelines:

The standards must be substantially analogous to those established in the IATA Airport Development Reference Manual and by ICAO in accordance with the Chicago Convention of 1944 (Exhibits 2, 4, 6, 9, 10, 11, 12, 14, 15, 16, 17 and 18).

Other airports located outside Argentina shall be used as a basis for comparison, according to size and type.

If the Concession Holder departs from the applicable standards, it shall be required to submit a written proposal to ORSNA for the latter’s approval.

Equipment must meet U.S. Government equipment quality test standards.

Quality of Service

In order to maintain Quality of Service at Group A Airports, ORSNA shall conduct an annual survey of passengers in accordance with sound statistical practices, and of all of the Air Carriers using Airport Group A, in or der to ascertain their opinions concerning the quality of the service provided at the airports. This survey shall be conducted at the Concession Holder’s expense. Before any survey is conducted, the Regulatory Body shall reach an agreement with the Concession Holder on the scoring system to be used in identifying through passenger responses those instances in which minimum service levels were not achieved.

Any survey whose results are below the agreed minimum levels shall be published in the Annual Service Report (see below).

The quality service survey shall be only one of the references used in measuring this indicator, and the same shall be evaluated by ORSNA specialists or third parties retained for the purpose, using systematic criteria.

ORSNA shall evaluate independently the desirability of conducting inspection services, and shall have the right to conduct the same, at all airports managed by the Concession Holder. No advance notice to the Concession Holder shall be required before conducting an inspection; advance notice of the aspects to be inspected shall be at the discretion of ORSNA. Inspections must be conducted at least once a year for each airport with passenger traffic exceeding 750,000.

ORSNA and the Concession Holder shall hold an annual informational meeting, at which the Concession Holder shall be notified of the results of the surveys and inspections, and of any complaints and comments received directly from airport users. At this meeting, the Concession Holder shall inform ORSNA of its plans for improving service.

The minutes of this meeting shall serve as the basis for an Annual Service Report to be prepared by ORSNA and published.

If, in the judgment of ORSNA, the Concession Holder is not meeting minimum service levels, the Concession Holder shall have 90 days to remedy the deficiencies, unless a different period is agreed upon with the Concession Holder. If the Concession Holder does not take the appropriate measures, ORSNA shall impose the penalties provided for under the Concession Contract.
