To the Company

drafts of documents reviewed by us have been signed in the form of those drafts, each copy of a document conforms to the original, each original is authentic, and each signature is the genuine signature of the individual purported to have placed that signature;

if any signature under any document is an electronic signature (as opposed to a handwritten (“wet ink”) signature) only, it is either a qualified electronic signature within the meaning of the eIDAS Regulation, or the method used for signing is otherwise sufficiently reliable;

the Registration Statement has been declared effective by the SEC in the form reviewed by us;

(i) no internal regulations (reglementen) have been adopted by any corporate body of the Company which would affect the validity of the resolutions recorded in the Resolutions, (ii) the Previous Articles were the Articles of Association in force at the time of execution of the B.V. Deeds of Issue and (iii) the Current Articles were the Articles of Association in force at the time of execution of the N.V. Deeds of Issue;

the resolutions recorded in the Resolutions are in full force and effect, the factual statements made and the confirmations given in the Resolutions and each Deed of Issue are complete and correct and the Resolutions correctly reflect the resolutions recorded therein;

each Deed of Issue has been validly signed and executed on behalf of the parties thereto;

the offering of any Warrants or Registered Shares, to the extent made in the Netherlands, has been made in conformity with the Prospectus Regulation and the rules promulgated thereunder;

the Warrants (i) have been validly granted as a right to subscribe for Ordinary Shares (recht tot het nemen van aandelen), (ii) shall be in full force and effect upon being exercised and (iii) shall have been validly exercised in accordance with the terms thereof;

at least the nominal value of the Warrant Shares shall be paid up upon exercise of the Warrants; and

at each Relevant Moment, each of the assumptions made in this opinion letter was and will be correct in all aspects by reference to the facts and circumstances then existing.

The Company has been duly incorporated as a besloten vennootschap met beperkte aansprakelijkheid and is validly existing as a naamloze vennootschap.

Assuming receipt by the Company of payment in full for the Ordinary Shares as provided for in the respective Deeds of Issue (including through the contributions referred to therein), the Ordinary Shares as provided for in the respective Deeds of Issue are validly issued, fully paid and non-assessable.

Subject to receipt by the Company of payment in full of (or otherwise satisfaction of) the exercise price for the Warrants as provided for in the Spartan Warrant Agreement, and when issued and accepted in accordance with the Resolutions and the Spartan Warrant Agreement, the Warrant Shares shall be validly issued, fully paid and non-assessable.

Opinion 1 must not be read to imply that the Company cannot be dissolved (ontbonden). A company such as the Company may be dissolved, inter alia by the competent court at the request of the company’s board of directors, any interested party (belanghebbende) or the public prosecution office in certain circumstances, such as when there are certain defects in the incorporation of the company. Any such dissolution will not have retro-active effect.

Pursuant to Section 2:7 DCC, any transaction entered into by a legal entity may be nullified by the legal entity itself or its liquidator in bankruptcy proceedings (curator) if the objects of that entity were transgressed by the transaction and the other party to the transaction knew or should have known this without independent investigation (wist of zonder eigen onderzoek moest weten). The Dutch Supreme Court (Hoge Raad der Nederlanden) has ruled that in determining whether the objects of a legal entity are transgressed, not only the description of the objects in that legal entity’s articles of association (statuten) is decisive, but all (relevant) circumstances must be taken into account, in particular whether the interests of the legal entity were served by the transaction. Based on the objects clause contained in the Previous Articles and the Current Articles, we have no reason to believe that, by entering into the Deeds of Issue, the Company has transgressed the description of the objects contained in its Articles of Association as were applicable at each Relevant Moment. However, we cannot assess whether there are other relevant circumstances that must be taken into account, in particular whether the interests of the Company are served by entering into the Deeds of Issue since this is a matter of fact.

Pursuant to Section 2:98c DCC, a naamloze vennootschap may grant loans (leningen verstrekken) only in accordance with the restrictions set out in Section 2:98c DCC, and may not provide security (zekerheid stellen), give a price guarantee (koersgarantie geven) or otherwise bind itself, whether jointly and severally or otherwise with or for third parties (zich op andere wijze sterk maken of zich hoofdelijk of anderszins naast of voor anderen verbinden) with a view to (met het oog op) the subscription or acquisition by third parties of shares in its share capital or depository receipts. This prohibition also applies to its subsidiaries (dochtervennootschappen). It is generally assumed that a transaction entered into in violation of Section 2:98c DCC is null and void (nietig). Based on the content of the Deeds of Issue, we have no reason to believe that the Company or its subsidiaries

The opinions expressed in this opinion letter may be limited or affected by:

rules relating to Insolvency Proceedings or similar proceedings under a foreign law and other rules affecting creditors’ rights generally;

the provisions of fraudulent preference and fraudulent conveyance (Actio Pauliana) and similar rights available in other jurisdictions to insolvency practitioners and insolvency office holders in bankruptcy proceedings or creditors;

claims based on tort (onrechtmatige daad);

sanctions and measures, including but not limited to those concerning export control, pursuant to European Union regulations, under the Sanctions Act 1977 (Sanctiewet 1977) or other legislation;

the Anti-Boycott Regulation, Anti Money Laundering Laws and related legislation;

any intervention, recovery or resolution measure by any regulatory or other authority or governmental body in relation to financial enterprises or their affiliated entities; and

the rules of force majeure (niet toerekenbare tekortkoming), reasonableness and fairness (redelijkheid en billijkheid), suspension (opschorting), dissolution (ontbinding), unforeseen circumstances (onvoorziene omstandigheden) and vitiated consent (i.e., duress (bedreiging), fraud (bedrog), abuse of circumstances (misbruik van omstandigheden) and error (dwaling)) or a difference of intention (wil) and declaration (verklaring).

The term “non-assessable” has no equivalent in the Dutch language and for purposes of this opinion letter such term should be interpreted to mean that a holder of an Ordinary Share shall not by reason of merely being such a holder be subject to assessment or calls by the Company or its creditors for further payment on such Ordinary Share.

This opinion letter does not purport to express any opinion or view on the operational rules and procedures of any clearing or settlement system or agency.
