Beta Service Addendum

to the Terms and Conditions of NexNurture s.r.o., operating as Newrails

Effective from: May 18, 2026

1. Purpose and relationship to the Terms and Conditions

This Beta Service Addendum ("Addendum") supplements and forms part of the Terms and Conditions of NexNurture s.r.o. ("Terms"). Capitalised terms used but not defined in this Addendum have the meanings given to them in the Terms.

This Addendum applies specifically to the USDC-related services provided by NexNurture s.r.o. during the transitional period described in Clause 1.2 of the Terms. In the event of any conflict between this Addendum and the Terms, the Terms shall prevail.

2. Nature of the USDC services

The USDC custody, EURW→USDC exchange, and USDC withdrawal services (together, the "USDC Services") are provided by NexNurture s.r.o. as part of an early-stage rollout. During this period:

• The USDC Services are provided on an "as-is" and "as-available" basis. The Company does not guarantee uninterrupted or error-free operation.
• Access is limited to a restricted number of existing Newrails clients who have completed the required onboarding steps.
• The feature set may be updated, expanded, or modified during this period.

3. Regulatory status and transitional period

NexNurture s.r.o. operates under the transitional regime described in Clause 1.2 of the Terms, pending the outcome of its MiCA licence application to the Czech National Bank. The Company makes no guarantee as to the timeline or outcome of that application.

Depending on the outcome of the MiCA application and other regulatory developments, the USDC Services may:

(a) continue and be formalised into a permanent offering if a MiCA or equivalent licence is obtained;

(b) be transitioned to an affiliated or third-party entity duly authorised to provide equivalent services; or

(c) be wound down in accordance with Section 11 of the Terms if no such authorisation is obtained.

The Company will notify clients through the Platform and by email in advance of any material change to the availability of the USDC Services. Please refer to Section 11 of the Terms for full details of the wind-down procedure.

4. EURW custody during the transitional period

Upon activation of the USDC Services, the custody of the Client's EURW is transitioned from Newrails UAB to NexNurture s.r.o., as described in the Terms. The Client's EURW balance and its fiat-pegged value are not affected by this transition.

In the event that the USDC Services are wound down:

• USDC: the Client must withdraw any USDC balance to their verified External Wallet. The Company will provide instructions and sufficient advance notice as set out in Section 11 of the Terms.
• EURW:the EURW held under VASP custody will be automatically migrated back to Newrails UAB (Lithuanian EMI) custody. The Client's EURW balance and fiat-pegged value will not be affected, and the Client may continue to use EMI services for EURW as normal.

5. Third-party and smart contract risks

The EURW→USDC exchange service utilises the Uniswap V3 decentralised protocol on the Monad blockchain. By using this service, the Client acknowledges and accepts the following risks:

• Smart contract risk — Uniswap V3 is a third-party decentralised protocol. Despite security measures, smart contracts may contain vulnerabilities.
• Liquidity and slippage risk — liquidity in the EURW/USDC pool may be limited, which may result in price impact or partial execution of Orders.
• Network risk — the Monad blockchain may experience congestion, failures, or protocol changes that may delay or disrupt transactions.
• Irreversibility — on-chain transactions are final once confirmed and cannot be reversed.

NexNurture s.r.o. provides the service interface and executes transactions on behalf of the Client but does not control the Uniswap V3 protocol or the Monad network. The Company's liability is limited as set out in Section 13 of the Terms.

6. Acceptance

By activating the USDC Services through the consent mechanism on the Platform, the Client confirms that it has read, understood, and agreed to this Addendum in addition to the Terms and the Privacy Policy of NexNurture s.r.o.
