1 INTRODUCTION

I act as Dutch legal adviser (advocaat) to the Issuer in connection with the Registration.

Certain terms used in this opinion are defined in Annex 1 (Definitions).

2 DUTCH LAW

This opinion is limited to Dutch law in effect on the date of this opinion. It (including all terms used in it) is to be construed in accordance with Dutch law.

3 SCOPE OF INQUIRY

I have examined, and relied upon the accuracy of the factual statements in, the following documents:

(a) A copy of:

(i) the Registration Statement; and

(ii) the Incentive Award Plan.

De Brauw Blackstone Westbroek N.V., Amsterdam, is registered with the Trade Register in the Netherlands under no. 27171912.

All services and other work are carried out under an agreement of instruction (“overeenkomst van opdracht”) with De Brauw Blackstone Westbroek N.V. The agreement is subject to the General Conditions, which have been filed with the register of the District Court in Amsterdam and contain a limitation of liability.

(b) A copy of:

(i) the Issuer’s deed of incorporation, the Deed of Conversion and Amendment, the Deed of Amendment and the Issuer’s articles of association, as provided to me by the Chamber of Commerce (Kamer van Koophandel); and

In this connection, reference is made to Annex 2 (Corporate changes).

(c) A copy of each Corporate Resolution.

In addition, I have also examined such documents, and performed such other investigations, as I considered necessary for the purpose of this opinion. My examination has been limited to the text of the documents.

4 ASSUMPTIONS

I have made the following assumptions:

(a)

(i) Each copy document conforms to the original and each original is genuine and complete.

(ii) Each signature is the genuine signature of the individual concerned.

(iii) The Registration Statement has been or will have been filed with the SEC in the form referred to in this opinion.

(b) Each Corporate Resolution and each other resolution referred to in this opinion:

(i) has been duly adopted (including, in the case of a shareholders’ resolution, by all persons entitled to vote on that resolution) and remains in force without modification; and

(ii) complies with the requirements of reasonableness and fairness (redelijkheid en billijkheid).

(c)

(i) At the time of each grant of a Stock Option or Stock Award and each issue of a Registration Share:

(A) the Incentive Award Plan remained and remains in full force and effect without modification (other than any change of the maximum aggregate number of Ordinary Shares that may be issued under the Incentive Award Plan);

(B) the aggregate number of (A) Ordinary Shares that have been issued or delivered, and (B) Ordinary Shares that will be issued or delivered, each time under the Incentive Award Plan, has not or will not exceed the maximum number permitted under the Incentive Award Plan; and

(C) the number of Ordinary Shares available for issue under the Issue Authorisation will be sufficient to allow for the grant or issue.

(ii)

(A) Each Stock Option and each Stock Award will be validly granted, accepted and (in case of a Stock Option) exercised in accordance with the Incentive Award Plan;

(B) Each Stock Option is and will be valid, binding and enforceable against each party; and

(C) The grant of each Stock Option and each Stock Award will have been validly authorised.

(iii)

(D) The issue by the Issuer of each Registration Share (or of any rights to acquire Registration Shares) will have been validly authorised; and

(E) any pre-emption rights in respect of each issue of Registration Shares (or of any rights to acquire Registration Shares) will have been observed or validly excluded;

all in accordance with the Issuer’s articles of association at the time of authorisation or of observance or exclusion.

(iv) The Issuer’s authorised share capital at the time of each grant of a Stock Option or a Stock Award and each issue of a Registration Share will be sufficient to allow for the grant or issue.

(v) Each Registration Share will have been:

(A) issued in accordance with the Incentive Award Plan and in the form and manner prescribed by the Issuer’s articles of association at the time of issue; and

(B) otherwise offered, issued and accepted by their subscribers in accordance with the Incentive Award Plan and all applicable laws (including, for the avoidance of doubt, Dutch law).

(vi)

(A) Each Registration Share will have been paid in cash or, if the Issuer’s board so approves in accordance with the Issuer’s articles of association at the time of issue, at the expense of the reserves of the Issuer; and

(B) The nominal amount of each Registration Share and any agreed share premium will have been validly paid.

5 OPINION

Based on the documents and investigations referred to and assumptions made in paragraphs 3 and 4 and subject to any matters not disclosed to me (including force (bedreiging), fraud (bedrog), undue influence (misbruik van omstandigheden) or a mistake (dwaling), in connection with issue of the Registration Shares) I am of the following opinion:

(a) When issued, the Registration Shares will have been validly issued and will be fully paid and nonassessable¹.

6 QUALIFICATIONS

(a) This opinion is subject to any limitations arising from (a) rules relating to bankruptcy, suspension of payments or Preventive Restructuring Processes, (b) rules relating to foreign (i) insolvency proceedings (including foreign Insolvency Proceedings), (ii) arrangement or compromise of obligations or (iii) preventive restructuring frameworks, (c) other rules regulating conflicts between rights of creditors, or (d) intervention and other measures in relation to financial enterprises or their affiliated entities.

¹ In this opinion, “nonassessable” – which term has no equivalent in Dutch – means, in relation to a share, that the issuer of the share has no right to require the holder of the share to pay to the issuer any amount (in addition to the amount required for the share to be fully paid) solely as a result of his shareholdership.

(b) An extract from the Trade Register does not provide conclusive evidence that the facts set out in it are correct. However, under the 2007 Trade Register Act (Handelsregisterwet 2007), subject to limited exceptions, a legal entity or partnership cannot invoke the incorrectness or incompleteness of its Trade Register registration against third parties who were unaware of the incorrectness or incompleteness.

7 RELIANCE

(a) This opinion is an exhibit to the Registration Statement and may be relied upon for the purpose of the Registration and not for any other purpose. It may not be supplied, and its contents or existence may not be disclosed, to any person other than as an Exhibit to (and therefore together with) the Registration Statement.

(b) Each person accepting this opinion agrees, in so accepting, that only De Brauw will have any liability in connection with this opinion, that the agreement in this paragraph 7(b) and all liability and other matters relating to this opinion will be governed exclusively by Dutch law and that the Dutch courts will have exclusive jurisdiction to settle any dispute relating to this opinion.

(c) The Issuer may:

(i) file this opinion as an exhibit to the Registration Statement; and

(ii) refer to De Brauw giving this opinion in the Exhibit Index in the Registration Statement.

The previous sentence is no admittance from me (or De Brauw) that I am (or De Brauw is) in the category of persons whose consent for the filing and reference as set out in that sentence is required under article 7 of the Securities Act or any rules or regulations of the SEC promulgated under it.

Yours faithfully,

De Brauw Blackstone Westbroek N.V.
