vii) The user's right to carry out counter operations, without restrictions on operation type –subject to those that may exist for operational reasons– nor on minimum amount, as provided in point 2.3.2.2. viii) The legend: “You may consult the “Transparency Regime” prepared by the BCRA based on information provided by obligated entities in order to compare costs, characteristics and requirements of financial products and services, by accessing https://www.bcra.gob.ar/regimen-de-transparencia/. ix) The right to request the opening of the Savings Account in pesos with the benefits provided for in point 1.8. of the TO on Savings, Salary and Special Deposits, which will be free of charge. x) The remaining legally regulated requirements according to the product or service in question. 2.3.1.2. Multiproduct contracts. Regarding freedom of choice of financial products or services provided by obligated entities, multiproduct contracts will be admitted to the extent that sections corresponding to each product can be separated into autonomous individual contracts, so that each user may adhere only to the product/s that effectively interest them. The revocation or rescission of a product or service that is part of a multiproduct contract may imply, when the obligated entity so provides, the loss of benefits and/or cancellation of remaining associated products or services, except savings accounts in pesos –when open– since they do not form part of multiproduct packages (point 1.4. of the TO on Savings, Salary and Special Deposits). In such cases, when an increase in the total cost of remaining products or services occurs, this circumstance must be previously informed to the financial services user indicating the available means to consult new values –as provided for in advertising matters in point 2.4.–. 2.3.1.3. Remote contracting of products and services. Whatever the modality used (telephone, by correspondence, by electronic means, promotion through third parties, etc.) obligated entities shall: − provide or make available to the financial services user a copy of the contract with the authorized signature of the obligated entity, within ten (10) business days after contracting or effective availability of the product or service, whichever occurs last; − use the usual documentation they employ in face-to-face contracts.

When it concerns modifications in commission and/or charge values duly accepted by the user, their consent to the change may be established by lack of objection within the term established in subsection iv). In credit card contracts, consent to modifications in agreed conditions (new commissions and/or charges) may only be given by the account holder. i) Notifications. Form, terms and effects. The financial services user must be notified of modifications to be applied by the obligated entity with a minimum advance of sixty (60) calendar days prior to their entry into force. Modifications that are economically more beneficial to the user –due to a reduction of agreed values– do not require advance notification. Notifications for changes in agreed conditions (new concepts and/or values or reduction of service benefits) will be free of charge for the financial services user in all cases. They must be carried out by written document addressed to the actual domicile of the financial services user –separately from any other information sent by the obligated entity (account summaries, informational bulletins, etc.), even if it forms part of the same dispatch– or by electronic means in cases where this is the form of communication. In the latter case, the notification must be clear, easily accessible to the user and include the issue date. In the body of these notifications, the following legends must be included:

• “You may opt to terminate the contract at any time before the change enters into force and free of charge, without prejudice that you must fulfill pending obligations under your responsibility”.
• “You may consult the “Transparency Regime” prepared by the BCRA based on information provided by obligated entities in order to compare costs, characteristics and requirements of financial products and services, by accessing https://www.bcra.gob.ar/regimen-de-transparencia/ Furthermore, when the value of commissions detailed below is modified, the body of notifications must display a comparative table for those amounts that will be prepared and timely made available by the Superintendence of Financial and Exchange Entities (SEFYC) on the site https://www.bcra.gob.ar/primeras-10-entidades/:
• Savings account: issuance of additional debit cards; replacement of debit cards due to theft or loss and use of ATMs (outside the entity's operating houses, another entity's and abroad).
• Credit cards: issuance, renewal, administration or account maintenance service; replacement or reprint of card due to theft or loss and additional cards. B.C.R.A. PROTECTION OF FINANCIAL SERVICES USERS Section 2. Basic rights of financial services users. Version: 16th. COMMUNICATION “A” 8433 Validity: 07/05/2026 Page 10

The charge that the obligated entity applies to the user may not be higher than that charged by the chosen insurance company for operations with individuals and without the intervention of the obligated entity, contracted at the place of contracting or domicile of the user. In no case may obligated entities register remuneration or profits for insurance that their users contract as accessory to a financial service –regardless of whether it is a user request or a condition established by the obligated entity to access the financial service–, so these concepts cannot integrate charges transferred to them nor be received directly or indirectly from the insurance company. 2.3.13. Insurance as non-accessory contracting to a financial service. Obligated entities may not receive from users any type of remuneration –commission and/or charge– additional to the premium determined by the insurer, linked with the intermediation activity of general insurance contracts provided for in point 3.1.2. of the TO on Complementary Services of Financial Activity and Permitted Activities. The premium that the obligated entity receives from the user may not be higher than the amount charged by the chosen insurance company for operations with individuals and without the intervention of the obligated entity. 2.3.14. Information to the user. Upon sending account summaries, the obligated entity must include –as applicable– the following legends in a visible place and with prominent letter size:

• “You may request the “Savings account” in pesos with the benefits provided for in point 1.8. of the TO on Savings, Salary and Special Deposits, which will be free of charge”. (Financial entities)
• “You may consult the “Transparency Regime” prepared by the Central Bank based on information provided by obligated entities in order to compare costs and characteristics of financial products and services by accessing https://www.bcra.gob.ar/regimen-de-transparencia/
• “Dollar consumption on your credit cards may be settled in that foreign currency or in pesos, with the selling exchange rate (applicable for operations carried out at the counter or through electronic means, as applicable) of the settlement moment applying as maximum in this case–or the immediate preceding business day when payment is made on a non-business day–. If you had agreed to automatic debit of the card statement, the selling exchange rate for operations carried out through electronic payment means at the close of the same business day of payment will apply”.
