the “Company”

Form F-3 Registration Statement

We have acted as Luxembourg legal advisers of the Company, in connection with the registration statement on form F-3 filed with the U.S. Securities and Exchange Commission (the “Commission”) under the U.S. Securities Act of 1933, as amended relating to the registration with the Commission of ordinary shares under registered form with a nominal value of EUR 1.- each of the Company (the “Ordinary Shares” and each an “Ordinary Share”) and warrants of the Company to purchase Ordinary Shares. In our capacity as special Luxembourg counsel of the Company, we have been requested to render an opinion as to certain Luxembourg legal matters in connection with the registration of (i) 32,208,500 Ordinary Shares currently issued by the Company and detailed in the Registration Statement (as defined below) (the “Issued Shares”), (ii) up to 6,250,000 Ordinary Shares (the “Public Warrant Shares”) issuable by the Company upon the exercise of the Public Warrants (as defined below) and (iii) up to 148,000 Ordinary Shares (the “Private Warrant Shares” and together with the Public Warrant Shares, the “Warrant Shares”) issuable by the Company in connection with the exercise of part of the Private Warrants (as defined below) (collectively, the “Transaction”).

1. Introduction

1.1 Transaction Documents

For the purposes of the opinions given in this opinion letter (the “Opinion Letter”), we have reviewed the following documents entered into in connection with the Transaction (the ”Transaction Documents”):

- 1 -

1.1.1 A copy of the registration statement on form F-3 filed with the Commission on 29 December 2022 (the “Registration Statement”);

1.1.2 A copy of the execution version of a State of New York law governed warrant agreement dated 7 December 2020 between DD3 Acquisition Corp. II (the “SPAC”) as issuer and Continental Stock Transfer & Trust Company (the “Warrant Agent”) as warrant agent (the “SPAC Warrant Agreement”) relating to the issuance of (a) an aggregate of 185,000 warrants (“Private Warrants”) by the SPAC, each Private Warrant entitling the holder thereof to purchase one share of SPAC class A common stock, par value USD 0.0001 per share, at an exercise price of USD 11.50 per share, subject to adjustment, and (b) an aggregate of 6,250,000 warrants (the “Public Warrants” and, together with the Private Warrants, the ”Warrants”) by the SPAC, each Public Warrant entitling the holder thereof to purchase one share of SPAC class A common stock at an exercise price of USD 11.50 per share, subject to adjustment.

1.1.3 A copy of the executed version of an assignment, assumption and amendment agreement dated 30 November 2021 between the Company, the SPAC and the Warrant Agent amending the terms of the Warrants (the “Warrant Amendment Agreement”) so that each Warrant, pursuant to the Warrant Amendment Agreement, ceased to represent a right to acquire the number of shares of SPAC class A common stock set forth in such Warrant and was converted in accordance with the terms of such Warrant Amendment Agreement into a right to acquire one Ordinary Share of the Company at an exercise price of USD 11.50 per share to be paid in cash only, on substantially the same terms (but with such changes as introduced by the Warrant Amendment Agreement) as were in effect immediately prior to the execution of the Warrant Amendment Agreement, under the terms of the Warrant Amendment Agreement.

1.2 Defined terms and Interpretation

Terms defined in the Transaction Documents shall have the same meaning in this Opinion Letter, unless otherwise defined herein (and in particular in paragraph 1.1 (Transaction Documents) and in Schedule 1 (Definitions)).

Headings in this Opinion Letter are for ease of reference only and shall not affect its interpretation.

In this Opinion Letter, Luxembourg legal concepts are expressed in English terms and not in their original French terms. The concepts concerned may not be identical to the concepts described by the same English terms as they exist under the laws of other jurisdictions. This Opinion Letter may therefore only be relied upon under the express condition that any issues of interpretation arising thereunder will be governed by Luxembourg law.

- 2 -

1.3 Legal review

We have not reviewed any documents other than the Transaction Documents and the Corporate Documents, and this Opinion Letter does not purport to address any legal issues that arise in relation to such other documents that may be or come into force between the Parties, even if there is a reference to any such documents in the Transaction Documents or the Corporate Documents or on the impact such documents may have on the opinions expressed in this Opinion Letter.

1.4 Applicable law

The opinions given in this Opinion Letter are confined to and given on the basis of Luxembourg law as currently applied by the Luxembourg courts as evidenced in published case-law. We have made no independent investigation of any other laws for the purpose of this Opinion Letter and do not express or imply any opinion in relation to any such laws. In particular, as Luxembourg qualified lawyers we are not qualified nor in a position to assess the meaning and consequences of the terms of the Transaction Documents under the relevant foreign governing or applicable law and we have made no investigation into such laws as a basis for the opinions expressed hereafter and do not express or imply any opinion thereon, including in relation to any implied terms, statutory provisions referred to therein or any other consequences arising from the entry into or performance under such Transaction Documents under such laws. Accordingly, our review of the Transaction Documents has been limited to the terms of such documents as they appear on the face thereof without reference to their respective governing laws or any other applicable law (other than Luxembourg law).

The opinions given in this Opinion Letter are given on the basis that it is governed by and construed in accordance with the laws of Luxembourg and will be subject to the jurisdiction of the courts of Luxembourg.

1.5 Assumptions and reservations

The opinions given in this Opinion Letter are given on the assumptions set out in Schedule 4 (Assumptions) and are subject to the reservations set out in Schedule 5 (Reservations). The opinions given in this Opinion Letter are strictly limited to the matters stated in paragraph 2 (Opinions) and do not extend to any other matters.

- 3 -

2. Opinions

We are of the opinion that:

2.1 Corporate existence

The Company is a company incorporated and existing in Luxembourg as a société anonyme and has been incorporated for an unlimited period.

2.2 Shares

The Issued Shares have been validly issued and fully paid, and the holder of such Issued Shares is not liable, solely because of his or her or its shareholder status, for additional payments to the Company or the Company’s creditors.

2.3 Warrant Shares

The Warrant Shares to be subscribed and issued in accordance with the Warrant Agreement following exercise of the relevant Warrants (if and when exercised in accordance with their terms under the Warrant Agreement), will be validly issued and fully paid, and the holder of such Warrant Shares will not be liable, solely because of his or her or its shareholder status, for additional payments to the Company or the Company’s creditors.

3. No Insolvency Proceedings

According to the Negative Certificate, no Judicial Decision opening Judicial Proceedings against the Company has been registered with the RCS on the date stated therein. The Negative Certificate does not indicate whether a Judicial Decision has been taken or a Judicial Proceeding has been opened. The registration of a Judicial Decision must be requested by the legally determined persons at the latest one month after the Judicial Decision has been rendered. As a consequence, a delay exists between the moment where the event rendering the registration with the RCS necessary occurs and the actual registration of the Judicial Decision in the RCS. It may furthermore not be excluded that no registration has occurred during the legally prescribed period of one month if no request for registration has been made. As a consequence, the Negative Certificate is not conclusive as to the opening and existence or not of Judicial Decisions or Judicial Proceedings and should not be relied upon as such. The Negative Certificate does, for the avoidance of doubt, not purport to indicate whether or not a petition or order for any of the Judicial Proceedings has been presented or made.

4. Scope of Opinion

We have not been responsible for advising any party to the Transaction other than the Company and the delivery of this Opinion Letter to any person other than the Company does not evidence an existence of any such advisory duty on our behalf to such person.

- 4 -

The filing of this Opinion Letter as an exhibit to the Registration Statement does not evidence the existence of any such advisory duty on behalf to any party other than the Company.

We have not considered and do not opine on whether the Registration Statement complies with any public offering of securities and/or stock exchange listing and admission to trading regulations, nor do we opine on the Registration Statement or/and on any securities laws disclosure requirements.

We express no opinion as to any taxation matters or transfer pricing matters generally or liability to tax which may arise or be suffered as a result of or in connection with the Transaction Documents or the Transaction or on the impact which any tax laws may have on the opinions expressed in this Opinion Letter.

No opinion (except to the extent expressly opined upon herein) is expressed or implied in relation to the accuracy of any representation or warranty given by or concerning any of the parties to the Transaction Documents or whether such parties or any of them have complied with or will comply with any covenant or undertaking given by them or any obligations binding upon them.

We express no opinion on any applicable licensing or similar requirements.

We express no opinion on the applicability of or compliance with the Regulation (EU) No 648/2012 of the European Parliament and of the Council of 4 July 2012 on OTC derivatives, central counterparties and trade repositories or any delegated or implementing regulations (together the “EMIR Regulations”), or of Regulation (EU) 2015/2365 of the European Parliament and of the Council of 25 November 2015 on transparency of securities financing transactions and of reuse and amending Regulation (EU) No 648/2012 or implementing regulations (“SFTR Regulations”) or any obligations arising for the parties pursuant to each of the EMIR Regulations and the SFTR Regulations.

We express no opinion with respect to any data protection matters relevant to or referred to in the Transaction Documents.

This Opinion Letter does not contain any undertaking to update it or to inform the Company of any changes in the laws of Luxembourg or any other laws which would affect the content thereof in any manner.

In this Opinion Letter we do not analyse the question of whether the Transaction Documents create legal, valid and enforceable obligations of any Party.

- 5 -

5. Purpose

This Opinion Letter is provided in connection with the Transaction and is issued solely for the purposes of the filing of the Registration Statement.

It may not be relied upon for any other purpose, or quoted or referred to in any public document, or filed with any government agency or another person, nor may its existence or contents be disclosed to any person, without, in any such case, our prior written consent, except that we consent to the filing of this Opinion Letter as an exhibit to the Registration Statement and to the reference to us under the caption “Legal Matters” contained in the Registration Statement. In giving such consent, we do not hereby concede that we are within the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended, or the rules and regulations of the U.S. Securities and Exchange Commission thereunder.
