Exhibit 4.1

TECHNICAL CONDITIONS FOR THE EXTENSION

The Organismo Regulador del Sistema Nacional de Aeropuertos (hereinafter called, ORSNA), represented in this act by its President Carlos Pedro Mario Aníbal Lugones Aignase and its Vice- president Fernando Muriel, and the Concessionaire Aeropuertos Argentina 2000 S.A. (hereinafter called, indistinctly, “the Concessionaire” or “AA2000”), represented in this act by its President Eng. Martín Antranik Eurnekian, both jointly called, “the Parties” meet to set forth the technical conditions for the Extension of the Concessions of the airports that are part of Group “A” of the National Airport System.

FIRST: CONCESSION PERIOD

Pursuant to the contract structure of the Concession, the ORSNA recommends the National Executive Power to extend the concession period for TEN (10) years, which shall thus expire on February 13, 2038.

SECOND: NECESSARY INFRASTRUCTURE

2.1  Given the need for short and medium term investments in airport infrastructure to strengthen the airport system, a non-excluding preliminary list of tentative projects and works (Annex I) is attached hereto. The ORSNA will prioritize the different items in this project bank and will decide the works that will be carried out in each period, pursuant to the financial goals set forth in the Economic- Financial Equation of the Concession. As regards the sources of funding for needed investments, the parties have made the following considerations:

2.1.1         The Concessionaire undertakes the commitment to assign a volume of funds amounting to USD 132 million (including VAT) as direct investment to cover unpaid expenses for physical progress certifications, to complete in 2020 and 2021 ongoing works currently considered as direct investment which are deemed necessary by the ORSNA, and to pay the VAT corresponding to unpaid certificates of works carried out with funds of the “Trust Fund for Works of Group A of Airports of the National Airport System”, of the “Additional Fund for Substantial Investments in Group A of Airports” and of the “Specific Trust fund for Works if the 2012 Project Bank.”

2.1.2         The Concessionaire promises to do its best effort and to contribute all expertise at hand to get the greatest leverage possible to obtain before 12/31/2021 funding that enables the company to have an early influx of up to USD 85 million in the “Trust Fund for Works of Group A of Airports of the National Airport System.” This volume shall neither include the balances of such account accrued up to December 2020 nor any income generated by other alternative sources other than aforementioned ones.

1

2.1.3         The Concessionaire promises to do its best effort and to contribute all expertise at hand to get the greatest leverage possible to obtain before 12/31/2021 funding that enables the company to have an early influx of up to USD 124 million in the “Additional Fund for Substantial Investments in Group A of Airports”. This volume shall neither include the balances of such account accrued up to December 2020 nor any income generated by other alternative sources other than aforementioned ones.

2.1.4         The Concessionaire promises to have before 03/31/2022 a volume of funds amounting to USD 406.5 million (VAT included). Such funds shall be used for the following purposes: (I) works considered as direct investment, to be carried out preferably during 2022/2023 and (ii) redemption of preferred shares of the National State performed by the Concessionaire before 03/31/2022, which shall be specifically allocated to airport infrastructure investments, as established in Decree 1799/07.

2.1.5         The Concessionaire undertakes the commitment to make Direct Investments for USD 200 million (VAT included) between the years 2024 and 2027 inclusive, at a rate of USD 50 million a year. This volume of investment shall be complementary to any Direct Investment balance carried forward from the 2021/2023 period, pursuant to the provisions of items 2.1.1) and 2.1.4) above, which are pending of execution by 2024.

2.1.6         Direct Investments for the 2028/2038 period shall be defined by the operative needs of the system and the balance of the concession.

2.2. With the purpose of providing an incentive to execute additional works, within the framework of the provisions of Clause 18 of the Memorandum of Agreement for Contract Renegotiation approved by Decree No 1799, of December 4, 2007 of the National Executive Power, the ORSNA may authorize the Concessionaire to execute contracts with third parties for a term longer than the term of effect of the Concession, as long as such term is justified by the magnitude of the investment and repayment thereof, and the Grantor or any person appointed by it may be subrogated to all rights and obligations of the Concessionaire at the end of the Concession.

2

THIRD: ECONOMIC-FINANCIAL EQUATION OF THE CONCESSION.

The indicative and conceptual REVENUE AND EXPENDITURE FINANCIAL PROJECTION OF THE CONCESSION (REFP) up to the year 2038 is attached hereto as Annex II.

The airport charges established in such financial projection aim to keep the balance of the Economic- Financial Equation of the Concession and the decision related to the final charges to be applied shall be based upon the Review Mechanism duly established and used by the ORSNA.

Financial obligations for March 2022, as stated in the previous clause, may be extended to December 2022, provided that there are external reasons not related to the parties that duly justify such extension, pursuant to ORSNA’s resolution, without detriment to the Investment commitments undertaken by the Concessionaire, which shall remain unaltered.

FOURTH: EXCLUSIVITY

4.1.          Pursuant to the provisions of clause 5.2 of the Concession Contract approved by Decree No 163 of the National Executive Power, of February 13, 1998, the exclusivity conferred pursuant to the provisions of clauses 3.11 and 4.1 of the Concession Contract shall be kept during the term of extension of the concession, with the following exceptions:

4.1.1.   Airport influence areas in the interior of the country shall no longer be applicable. This provision does not include the Metropolitan Region of Buenos Aires (RMBA, as per the acronym in Spanish), which comprises the airports of Ezeiza, Aeroparque, San Fernando and El Palomar. Exclusivity for fiscal warehouse activities in the airport influence areas shall be kept in all the national territory.

4.1.2   New airport infrastructure projects in the Río de la Plata promoted by the National Public Sector, as stated in section 8 of Law 24 156, shall not be subject to exclusivity and included in the airport influence area when such activities cannot be funded and operated by the Concessionaire due to the characteristics thereof.

For such purposes, the ORSNA shall assess, after receiving the corresponding report from the Concessionaire, the possibility to carry out the project according to the provisions of clauses 4.3 or 4.4 of the Concession Contract.

4.1.3   Intercargo S.A. shall keep the concession of ground handling services, and shall thus pay the Concessionaire the agreed fees and prices. If the National State decides to terminate, cancel or conclude the concession contract for the service rendered by Intercargo S.A., the concession for such services shall be transferred to the Concessionaire, who shall render the services on its own or through a third party or parties hired for that purpose.

3

FIFTH: MAINTENANCE OF THE STATE’S SHARE OWNERSHIP.

The National State shall keep its 15% share of Aeropuertos Argentina 2000 S.A.’s ordinary capital and shall hold its rights to such shares up to the end of the Concession period, also keeping the intangibility of such shares with no need to pay any compensation whatsoever to the Concessionaire for them.

SIXTH: WAIVER OF CLAIMS

Within TEN (10) working days of the effective date of the present Agreement,

6.1. The Concessionaire shall prove its waiver of all claims, remedies and filed or ongoing lawsuits against the National State and/or its decentralized entities, both in administrative, arbitration or court proceedings, for any cause or, if applicable, it shall demonstrate it has obtained the corresponding judicial approval whenever the parties involved deem it necessary.

6.1.1.   Such waiver shall not imply an acknowledgment of the situation that originated the claim, remedy or lawsuit. In the specific case of fines imposed to the Concessionaire, in connection to which the Concessionaire has filed claims and/or legal proceedings, such actions shall be waived for the purpose of granting the extension that is the object of the present Agreement, and this waiver shall not be understood as an acknowledgment of the legitimacy of such fines.

6.1.2.   The waiver or judicial approval shall include a request that each party bears its own costs.

6.2. The Concessionaire shall submit to the ORSNA the duly certified and legalized instruments that expressly and fully state the waiver of rights and actions pursuant to the provisions of the preceding paragraph.

6.3. If upon the end of the term established in clause SIX the Concessionaire has not submitted proof of the corresponding waiver or judicial approval, the ORSNA shall cancel the application of the present Agreement. In such case, the ORSNA shall notify the Concessionaire of the breach and demand compliance with the committed waiver within a new term of 15 (fifteen) days.

6.4. After this term and upon failure by the Concessionaire to submit proof of the committed waivers or, if applicable, the corresponding judicial approval, the ORSNA may withdraw from the agreement for a cause attributable to the Concessionaire.

4

SEVENTH: TERM OF EFFECT.

7.1. The following conditions are necessary for this Agreement to be effective:

7.1.1.        The submission of the Concessionaire’s Minutes of the Meeting of the Board of Directors approving and authorizing the execution of the present Agreement.

7.1.2.  The decision by the National Executive Power to issue a decree approving the extension of the Concession period in the conditions established herein and approving the present Agreement.

7.2          The Concessionaire hereby acknowledges and accepts that the extension is a discretionary decision of the National Executive Power and thus the Concessionaire expressly accepts that, if the National Executive Power decides not to extend the concession, the Concessionaire shall not be entitled to any compensation whatsoever for this reason.

7.3           Upon breach by the Concessionaire of the technical conditions established herein, the corresponding penalties established in the Concession Contract (Decree No 163/98) and the Memorandum of Agreement for Contract Renegotiation (Decree No 1799/07) shall be applied.
