The purpose of this
notice is to inform you about the issuance of Resolution No 9, dated on January 28, 2009, by the ORGANISMO REGULADOR
DEL SISTEMA NACIONAL DE AEROPUERTOS (ORSNA), which provides as follows in Article 1: “To approve the Review of the Financial
Projection of Income and Expenses (FPIE) for the period 2006-2007, pursuant to the provisions of Paragraph 29 of Part Four of the
Memorandum of Agreement for Concession Contract Adjustment, ratified by Decree 1799/07, which states the need to balance the variables
included in the FINANCIAL PROJECTION OF INCOME AND EXPENSESS OF THE CONCESSION (FPIE) based on an average rate variation of THIRTY
FIVE PERCENT with 7/100 (35.7%), which will be applied to all International Charges except for the TELESCOPIC JET WAY USAGE FEE.
Likewise, it is necessary to fix the value of the DOMESTIC AIRPORT TERMINAL USAGE FEE to FOURTEEN PESOS WITH 50/100 ($14.50) for
First Category Airports and TEN PESOS WITH 15/100 ($10.15) for the rest of the Airports.” Article 2 of said Resolution provides

BUENOS AIRES, JANUARY
28, 2009


 


Having
reviewed File N° 563/08 of the Registry of the ORGANISMO REGULADOR DEL SISTEMA NACIONAL DE AEROPUERTOS (ORSNA), Decree N°
375, dated on April 24, 1997, ratified by Decree of Necessity and Urgency N° 842, dated on August 27, 1997, Decree N° 163,
dated on February 11, 1998, Decree No 1799, dated on December 4th. 2007, ORSNA Resolution No 111, dated on December 30,
2008, and,


 


WHEREAS:


 


The
abovementioned File deals with the Review of the Financial Projection of Income and Expenses
for the CONCESSION (FPIE), corresponding to the years 2006-2007.


 


Paragraph
24.1 of the Memorandum of Agreement for Concession Contract Adjustment, ratified by Decree No 1799/07 establishes the Financial
Projection of Income and Expenses (FPIE) for the Concession for the 2006-2028 period.


 


Said
projection is shown in Annex 5 of the Memorandum of Agreement and consists of a breakdown of revenues and expenditures related
to the rendering of the services subject to the concession, including the investment obligation and the balance of the mutual claims
between the NATIONAL STATE and the Concessionaire AEROPUERTOS ARGENTINA 2000 SOCIEDAD ANÓNIMA.


 


Paragraph
6.5 of Part Four of the Memorandum of Agreement states that ordinary and extraordinary reviews of the Financial
Projection of Income and Expenses for the concession (FPIE) shall be carried out when required by the circumstances.


 


Paragraphs
29.1 and 29.2 of the Memorandum of Agreement provide for an Annual Ordinary Review Mechanism of the Financial
Projection of Income and Expenses for the concession (FPIE), with the purpose of verifying and keeping the balance between
the variables of the aforementioned projection.


 




     


    	 	“2009 – Year of Homage to Raúl SCALABRINI ORTIZ”



    

 


Likewise,
Paragraph 29.4 states as follows: “At the moment of the first review of the FINANCIAL PROJECTION OF INCOME AND EXPENSES FOR
THE CONCESSION (FPIE) the ORGANISMO REGULADOR DEL SISTEMA NACIONAL DE AEROPUERTOS (ORSNA) shall analyze the convenience and pertinence
of: a) promoting a charge reduction system of at least TWENTY-FIVE PERCENT (25%) for airline companies that offer new flights after
the aforementioned review with the purpose of boosting international flight offers to Argentina at the airports subject to the
Concession; b) apply such charge reduction in face of passenger traffic increase in excess of the contractual estimates, applying
a THREE PERCENT (3%) discount to international charges for airlines for each percentage point of growth in excess of the contractual
estimates, up to a maximum discount of FIFTEEN PERCENT (15%); propose a rate rebalancing system to guarantee the protection of
the domestic air navigation system user and of the systemic competitiveness of the navigation model with the following purposes:
i) promote domestic flights with reductions and/or removal of the domestic airport terminal usage fee; ii) reduce international
charges for Airlines by THIRTY PERCENT (30%) ; and iii) readjust international airport terminal usage fees.”


 


The
aforementioned mechanism was submitted to the MINISTRY OF TRANSPORTATION through ORSNA Resolution No 111/08, which states
the necessary methodology to achieve the rebalancing of the Financial Projection of Income
and Expenses for the concession (FPIE), in case of any substantial imbalances affecting such projection.


 


The
Concessionaire, through Note dated October 3, 2008 (Note AA2000-DIR-720/08), states the economic problems that, in their opinion,
were caused by acts of third parties which have resulted in a serious imbalance of the FINANCIAL PROJECTION OF INCOME AND EXPENSES
OF THE CONCESSION (FPIE), and asks the ORGANISMO REGULADOR DEL SISTEMA NACIONAL DE AEROPUERTOS (ORSNA) to analyze and apply different
measures to adapt the FINANCIAL PROJECTION OF INCOME AND EXPENSES OF THE CONCESSION (FPIE) to the new circumstances.


 




     


    	 	“2009 – Year of Homage to Raúl SCALABRINI ORTIZ”



    

 


The
ORGANISMO REGULADOR DEL SISTEMA NACIONAL DE AEROPUERTOS (ORSNA) considers that the circumstances affecting the airport market and
those circumstances related to local and international context make it necessary to analyze the review of the FINANCIAL PROJECTION
OF INCOME AND EXPENSES OF THE CONCESSION (FPIE).


 


The
price variation analysis related to the FINANCIAL PROJECTION OF INCOME AND EXPENSES OF THE CONCESSION (FPIE) shows that since January
1, 2006 ─ effective date of the Memorandum of Agreement ─ to December 31, 2007, the Rate of Exchange increased by FOUR
PERCENT (4%), the Consumer Price Index (CPI) increased by NINETEEN (19%) PERCENT, the Wholesale Domestic Price Index (IPIM, as
per the acronym in Spanish) increased by TWENTY-THREE PERCENT (23%) and the Construction Cost Index (CCI) increased by FORTY-THREE
PERCENT (43%), a figure that is similar to the registered variation in the Salaries category, all of which are based on the data
provided by the INSTITUTO NACIONAL DE ESTADÍSTICAS Y CENSOS (INDEC).


 


The
price variations in our country have had a negative impact on the FINANCIAL PROJECTION OF INCOME AND EXPENSES OF THE CONCESSION
(FPIE), and have affected to a lesser degree the indexes related to revenues, as compared to those related to expenditures (costs
and investments).


 


As the Memorandum of
Agreement for Concession Contract Adjustment, ratified by Decree 1799/07, affects the Review corresponding to years 2006 and 2007,
the First Review of the Projection shall be temporary in nature until Regulatory Accounting Procedures and Actions enable to perform
a complete analysis of the cost and income structure of the Concession, and such review shall focus on the investments made in
Group “A” of the NATIONAL AIRPORT SYSTEM (NAS) for the 2006-2007 period, whereas the review of the revenues and expenditures
of the concession is still ongoing.


 


It should be mentioned
that the ORGANISMO REGULADOR DEL SISTEMA NACIONAL DE AEROPUERTOS (ORSNA), through ORSNA Resolution No. 1/09, provided for the entry
in the Record of Investments of the amount of FIFTY-SEVEN MILLION EIGHT HUNDRED AND SIXTY-EIGHT THOUSAND FOUR HUNDRED AND FIFTY-SEVEN
PESOS WITH 16/100 (ARS57,868,457.16) for the 2006 period and the amount of SIXTY-NINE MILLION EIGHT HUNDRED AND NINETY-THREE THOUSAND
SIX HUNDRED AND FIFTY SEVEN PESOS WITH 93/100 (ARS69,893,657.93) for the 2007 period.


 




     


    	 	“2009 – Year of Homage to Raúl SCALABRINI ORTIZ”



    

 


As regards revenue-related
data, the information arising from the Company’s Balance Sheets, duly audited by PRICE & WATERHOUSE CO., was used as
basis for the review, making the corresponding consistency tests for both aeronautical and non-aeronautical revenues, with no significant
differences between the revenues entered in the Company’s Financial Statements and the consistency tests performed. Without
prejudice to the aforementioned, in case of differences resulting from the analysis of Regulatory Accounting, such differences
shall be assessed in the following review of charges.


 


As regards expenditures,
the ORGANISMO REGULADOR DEL SISTEMA NACIONAL DE AEROPUERTOS (ORSNA) has adopted the criterion of the UNIT FOR THE RENEGOTIATION
AND ANALYSIS OF PUBLIC SERVICE CONTRACTS (UNIREN), which is based on working with the information included in the proposal until
all Regulatory Accounting Procedures have been drawn up, adjusting the pertinent data included in the Memorandum of Agreement by
the price variation indexes associated to each row of the Projection.


 


It should be mentioned
that the provided model addresses strictly economic aspects, and financial issues should be analyzed at the first ordinary meeting,
as the present review is only temporary in nature and is only intended to restore the impaired balance due to factors related to
price index variations.


 


By virtue of the aforementioned,
the circumstances related to payment defaults for the period or those circumstances related to the performance of the commitments
arising from the Specific Revenue Allocation (SRA) have not been analyzed. Such circumstances shall be analyzed at the proper time,
after the corresponding mechanisms (Regulatory Accounting, Trust) have been established and implemented.


 




     


    	 	“2009 – Year of Homage to Raúl SCALABRINI ORTIZ”



    

 


The necessary average
rate increase amounts to THIRTY-FIVE WITH 7/100 (35.7%), applicable to all aeronautical charges collected by AEROPUERTOS ARGENTINA
2000 SOCIEDAD ANÓNIMA, except for the telescopic jet way usage fee, which does not require an adjustment, based on the comparison
with identical services provided by other airports in the world.


 


In such sense, for the
purpose of future revenue calculation, given that the FINANCIAL PROJECTION OF INCOME AND EXPENSES (FPIE), as stated in Annex 5
of the Memorandum of Agreement, was performed taking into account a) an unchanged nominal exchange rate over the period under consideration,
and b) a zero rate of inflation for all and each of the years under consideration, no modifications have been made updating the
nominal exchange rate based on the most recent market data obtained.


 


On the other hand, as
regards the provisions of item 8.4 of the aforementioned Mechanism, the provisions of Paragraph 29.4 of the Memorandum of Agreement
shall be complied with, as stated in the preceding Clauses.


 


Based on the aforementioned,
the ORGANISMO REGULADOR DEL SISTEMA NACIONAL DE AEROPUERTOS (ORSNA), AEROPUERTOS ARGENTINA 2000 SOCIEDAD ANÓNIMA and the
representatives of the INTERNATIONAL AIR TRANSPORT ASSOCIATION (IATA) entered into an Agreement on September 19, 2008 to provide
for a discount on international charges, through credit notes to be applied from the month of September 2008 up to the end of the
review by the ORGANISMO REGULADOR DEL SISTEMA NACIONAL DE AEROPUERTOS (ORSNA).


 


As regards the criteria
to be considered for applying the discounts to airlines, the provisions of Article 6 of the aforementioned Agreement should be
complied with. This Article states as follows: “Discounts and credit notes shall not be granted to those airlines that are
not up to date with their payments (for these purposes, an airline shall not be considered in default if there are any judicial
claims related to Decrees 577/02 and 191/02 for accrued amounts prior to Decree 1799/07).”


 


Discounts shall be granted
in such a manner that once applied over the values included in the Rate Schedule they represent a THIRTY PERCENT (30%) discount
over the applicable values at the time of execution of the Memorandum of Agreement between the INTERNATIONAL AIR TRANSPORT ASSOCIATION
(IATA), the ORGANISMO REGULADOR DEL SISTEMA NACIONAL DE AEROPUERTOS (ORSNA) and AEROPUERTOS ARGENTINA 2000 SOCIEDAD ANÓNIMA.


 




     


    	 	“2009 – Year of Homage to Raúl SCALABRINI ORTIZ”



    

 


Given the existing balance
between the variables of the Concession, this type of discount results in an imbalance of the economic equation, and thus it becomes
necessary to provide for a mechanism to implement this policy without affecting the normal financing of airport services.


 


The ORGANISMO REGULADOR
DEL SISTEMA NACIONAL DE AEROPUERTOS (ORSNA) made a comparison between the airport charges paid in different countries, the evolution
of which is subject to periodical follow-up.


 


This comparison shows
that in the case of airport charges paid by airport operators in international flights, the values are similar to the average value
paid in the countries that were used in the comparison. On the contrary, when analyzing the charges paid by international passengers,
they are way below the average charges paid in other airports.


 


In the case of the DOMESTIC
AIRPORT TERMINAL USAGE FEE, the disparity with the values charged in other countries is even more notorious, as the DOMESTIC AIRPORT
TERMINAL USAGE FEE charged in the REPUBLIC OF ARGENTINA is lower than TWO US DOLLARS (USD2.00) and the average for the selected
countries is FIFTEEN US DOLLARS (USD15).


 


Notwithstanding the observed
variations in most prices in the 1998-2008 period, which are reflected in a ONE HUNDRED AND SEVEN PERCENT (107%) increase of the
Consumer Price Index (CPI), a TWO HUNDRED AND FOURTEEN PERCENT (214%) increase of the Construction Cost Index (CCI), and a TWO
HUNDRED AND TWENTY-FIVE PERCENT (225%) increase of the Wholesale Domestic Price Index (IPIM, as per the acronym in Spanish), both
national and international Airport Terminal Usage Fees have kept the values established in the Concession Contract.


 


Likewise, taking into
account the price variations observed in the 1998-2008 period, and given that this variation affected the airports that are part
of Group “A” of the NATIONAL AIRPORT SYSTEM (NAS), a decision should be made to adjust these airport charges by the
same percentage.


 




     


    	 	“2009 – Year of Homage to Raúl SCALABRINI ORTIZ”



    

 


Based on the preceding
Clauses, a decision should be made as to the need to increase all International Charges by THIRTY FIVE PERCENT WITH 7/100 (35.7%),
except for the telescopic jet way usage fee, and fix the value of the DOMESTIC AIRPORT TERMINAL USAGE FEE to FOURTEEN PESOS WITH
50/100 (ARS14.50) for First Category Airports and TEN PESOS WITH 15/100 (ARS10.15) for the rest of the Airports.


 


The Memorandum of Agreement
for Concession Contract Adjustment, as legal instrument, provides for an annual periodic review mechanism intended to assess the
evolution of the different variables that are part of the projection and make the corresponding adjustments to guarantee the economic
efficiency of the Concession.


 


Such mechanism is part
of the modifications included in the Memorandum of Agreement of the Concession Contract, approved by Decree 163/98.


 


In this sense, the procedure
for the Review of the FINANCIAL PROJECTION OF INCOME AND EXPENSESS OF THE CONCESSION (FPIE) was added as a tool to defend the sustainability
of the Concession.


 


In this respect, it should
be mentioned that the dynamics of the Concession, in light of the provisions of the Memorandum of Agreement, make it necessary
to perform a periodic audit and review of the results of the Review of the FINANCIAL PROJECTION OF INCOME AND EXPENSESS OF THE
CONCESSION (FPIE), so any deviation, whether related to excess or shortage situations, shall be later corrected by the ORGANISMO
REGULADOR DEL SISTEMA NACIONAL DE AEROPUERTOS (ORSNA).


 


Therefore, adjusting
the economic aspect of the Concession to achieve financial balance is a dynamic, ongoing task that requires permanent control and
correction of the different variables that are part of the FINANCIAL PROJECTION OF INCOME AND EXPENSES OF THE CONCESSION (FPIE).


 


The ECONOMIC FINANCIAL
REGULATION AND QUALITY CONTROL DEPARTMENT (GREFyCC, as per the acronym in Spanish) and the LEGAL DEPARTMENT (GAJ, as per the acronym
in Spanish) have acted in exercise of their incumbent authority.

The
ORGANISMO REGULADOR DEL SISTEMA NACIONAL DE AEROPUERTOS (ORSNA) has the corresponding authority to issue the present measure, pursuant
to the provisions of Section 3 of the National Law of Administrative Procedures No. 19 549 and other aforementioned regulations.


 


The
matter was discussed at a Meeting of the Board of Directors held on January 22, 2009 and the undersigned was authorized to issue
the present decision.


 


Therefore,


 


THE
BOARD OF DIRECTORS OF THE ORGANISMO REGULADOR


 


DEL
SISTEMA NACIONAL DE AEROPUERTOS


 


RESOLVES:

of Agreement. Such discount shall be applied to those airlines that are up to date with their payments, and all invoices issued
by AEROPUERTOS ARGENTINA 2000 SOCIEDAD ANÓNIMA shall specify the discount amount.
