Preliminary Sales Contract

By and among:

The Seller and the Purchaser will be jointly referred to as the “Parties” and individually as the “Party”; and

Whereas:

1. The Seller is a joint owner of the real estate located in the District of Vicente López, Province of Buenos Aires, at Avenida del Libertador Gral. San Martín Nº 77, with the following cadastral ID: Circumscription III; Section D, Fraction II, Lot 1T, License No. 49,432 (“Lot 1T”); and

2. Lot 1T is to be subjected to the condominium system (Act No. 13,512) for the construction and building of an office building which will be called “TORRE AL RIO I” (“TORRE AL RIO I”).

Page 1 of 11

4. In turn, the final measures, percentages, surfaces and names of the Units will result from the Condominium Rules and Regulations (Act No. 13,512) which will be timely granted by the Seller based on the corresponding Survey Plan under the Condominium System finally approved by the competent authorities. The percentage corresponding to the Functional Units will represent approximately 10.20 % of the total surface of TORRE AL RIO I, as considered from level 0 to and including the rooftop terrace at the time of their notarization, which percentage will timely be indicated in the Condominium Rules and Regulations. This percentage will be modified in case the number of square meters built for commercial purposes is modified in the Project, keeping the percentage on the total constructed area and the attribution of common spaces in TORRE AL RIO I.

5. Furthermore, TORRE AL RIO I will be constructed and finished pursuant to the Leed V.3 CORE & SHELL certification.

6. The Seller’s rights to build TORRE AL RIO I and to assign the Units subject-matter hereof result from several agreements entered into between the Seller and the Joint Owners. A summary of the main terms and conditions of these agreements are attached hereto as Schedule I.

Therefore, the Parties agree to enter this preliminary sales contract pursuant to the following terms and conditions (the “Preliminary Sales Contract”):

Section One: Subject-Matter

1.1. Subject to the terms and conditions of this Preliminary Sales Contract, the Seller sells ad corpus, and the Purchaser jointly purchases the following Units of the building being constructed under the parameters of the Leed V.3 CORE & SHELL certification and provisionally called TORRE AL RIO I:

Section Two: Characteristics of the Units

2.1. The finishes, equipment, accessories and other characteristics of TORRE AL RIO I and the Units are based on the technical and descriptive memorandum attached hereto as Schedule A and Schedule B, which make up this Preliminary Sales Contract.

2.2. The Seller may introduce variations in finishes and/ or substitutions to the equipment and accessories promised for common areas of TORRE AL RIO I, provided they are replaced by finishes and/ or equipment having similar purpose, use, function and quality characteristics. Modifications, variations and/ or substitutions made by the Seller pursuant to this Section will not entitle the Purchaser to seek either the termination or cancellation of the contract or a price adjustment/ modification, or any compensatory or indemnity claim it may deem to be entitled to.

2.3. The Purchaser consents to the implementation of modifications of details in the Units’ plans and plots which may be necessary at the project management and/ or the competent authorities’ reasonable criteria provided they do not substantially modify the project and/ or the characteristics of the Units.

2.4. Units will be delivered vacant, and it is expressly agreed that the Purchaser may not object to their reception because the Building’s general details’ finishes are not completed, provided they do not affect the specific functioning or use of the Units, or the Building as a whole. Should there be, at the Purchaser’s discretion, minor flaws or details imperfections or any other objection regarding the Units’ finishes, it will receive them, and said flaws will be indicated in a record to be drawn up upon delivery, which will also include any remark the Purchaser wishes to make a reservation of its rights.

2.5. Notwithstanding the above provisions, should a modification of the Units result in a decrease or increase in the Unit’s number of square meters destined to office space referred to in Section 1.a, and provided said modification is higher than five percent (5%) of the total number of square meters corresponding to each Functional Unit individually considered, the Parties will make a pro rata Price modification based on the increased or decreased number of square meters exceeding the referenced percentage, and the provisions of Section 1.345 in fine of the Civil Code will not apply.

Section Three: Price and Means of Payment

3.1. The sale subject-matter hereof will be conducted pursuant to Condominium Act No. 13.512, ad corpus, and the Units price will amount to SEVENTEEN MILLION, SEVEN HUNDRED AND THIRTY-FIVE THOUSAND, ONE HUNDRED UNITED STATES DOLLARS (US$ 17,735,100), plus the applicable Value-Added Tax (the “Price”), which, to such effects, is provisionally calculated at a twenty percent (20%) rate. Taking into consideration the current tax legislation in force, the VAT will only be assessed on the value of the construction, and said assessment will be made according to the costs proportion attributable to the construction with reference to the building’s total costs. Therefore, the applicable VAT amount will be made based on a pro rata calculation of costs, which will be finally adjusted with the last payment described in Section “3.1.(ii)” below. The Price will be cancelled as follows:

3.2.

Furthermore, in such cases, all collection expenses will be borne by the Purchaser.

3.3. The amounts stated above should be cancelled in pesos at the exchange rate for sales operations published by Banco de the Nación Argentina on the last business day before the applicable cancellation date.

3.4. Both Parties declare that they have thoroughly and carefully analyzed the involved markets’ current situation, especially the financial and the real estate markets, and state that they have taken into consideration the possibility of there being fluctuations or modifications in said markets and, therefore, expressly and irrevocably waive the theory of unforeseen events, excessive contractual imbalance, major injury, abuse of rights and/ or any of the payment obligations with a currency or in an amount different from that foreseen, as well as any review of the agreement or a decrease in the Units’ Price.

Section Four: Building and Project

4.1. The Parties expressly acknowledge that the real estate development to be conducted in the Lots (the “Project”) is made up of a series of real estate projects destined to multiple uses, the construction of which and which opening date are uncertain and subject to the applicable approvals and authorizations by the competent authorities. Furthermore, the Project and its different initiatives may suffer several modifications. In this sense, and in the understanding that the other undertakings of the Project are expressly excluded from the subject-matter hereof, the Purchaser may not claim either the adjustment or the modification of the Price, or seek any other compensatory or indemnity claim in case the Project is not wholly implemented.

The Seller does hereby reserve the following rights: (i) the right to create more or fewer Functional Units in TORRE AL RIO I, to join and/ or divide Functional Units, to transform common areas into own areas or vice versa, provided said transformation does not exceed two percent (2%) of the Functional Units or the ground level, and to modify percentages, but only as long as said modification does not affect the Purchaser’s rights on the Functional Units or the Purchaser’s percentage over TORRE AL RIO I; (ii) the right to totally or partially enable the Units by modifying the Master Plan, the Condominium Division Plan and the Condominium Rules and Regulations so as to subject the Units to be created and/ or modified to the Condominium System, taking on all resulting expenses and procedures, (iii) the right to modify details of the original TORRE AL RIO I Project and/ or any of its projected sectors provided they do not substantially alter the project if it is deemed necessary, at the Seller’s reasonable discretion and/ or in case it is required by the competent authorities for the approval of the final condominium subdivision plan; and, (iv) the right to create, acknowledge and/ or recognize between the Units, plots, fractions and/ or sectors of the Project and/ or over them and/ or between them and other real estate, all restrictions or limitations to ownership, easements (whether active or passive, personal or real, reciprocal or unilateral) and any real or personal rights, as well as their modification, extension or reformation or any other rights to be hereinafter created which are necessary and/ or convenient, at the Seller’s reasonable discretion, for the development, making up, use, functioning, integration and utilization of the Project and/ or its different sectors as long as the use or functionality of the Functional Units are not negatively affected. On the other hand, the Purchaser may not divide TORRE AL RIO I’s Functional Units in more than three (3) Functional Units per floor it is acquiring pursuant to this Preliminary Sales Contract, or transform common areas into own areas or modify percentages except as provided for herein. Furthermore, it may not lease, sublease or grant a beneficial interest or right of use over a floor or a Functional Unit when it implies its physical division into more than three (3) Units.

The Seller undertakes to include this restriction into TORRE AL RIO I´s Condominium Rules and Regulations to be drawn up to subject the real estate to Act No. 13,512.
