1    INTRODUCTION

I act as Dutch legal adviser (notaris) to FCA 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 the Registration Statement.

(b)    A copy of the Merger Proposal.

(c)    A draft of the Deed of Merger.

(d)    A copy of:

(i)    FCA's deed of incorporation and its articles of association, as provided by the Chamber of Commerce (Kamer van Koophandel);

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.
Client account notaries ING Bank IBAN NL83INGB0693213876 BIC INGBNL2A.

In addition, I have 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)    

(i)    The Merger Proposal has been validly executed by all parties in the form referred to in this opinion.

(ii)    

(A)    Each step, resolution, action and/or (other) formality which is required for the implementation of the Merger (other than the execution of the Merger Proposal), including each step, resolution, action and/or (other) formality as set out in the Deed of Merger, has been or will have been validly taken; and

(B)    In general, the Merger will have been validly implemented in accordance with the Merger Proposal and all applicable laws (including, for the avoidance of doubt, Dutch law and French law).

(iii)    The Deed of Merger will have been validly executed by the Merging Companies in the form referred to in this opinion.

5    OPINION

Based on the documents and investigations referred to and assumptions made in paragraphs 3 and 4 and subject to the qualifications in paragraph 6 and any matters not disclosed to me, I am of the following opinion:

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

6    QUALIFICATIONS

This opinion is subject to the following qualifications:

(a)    This opinion is subject to any limitations arising from (a) rules relating to bankruptcy, suspension of payments or emergency measures, (b) rules relating to foreign insolvency proceedings (including foreign Insolvency Proceedings), (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. 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 and may not be relied upon for any purpose other than the Registration.

(b)    Each person accepting this opinion agrees, in so accepting, that:

(i)    only De Brauw (and not any other person) will have any liability in connection with this opinion;

(ii)    this opinion and any contractual (including the agreements in this paragraph 7) and non-contractual obligations arising out of or in relation to this opinion will be governed exclusively by Dutch law; and

(iii)    this opinion (including the agreements in this paragraph 7) does not make the persons accepting this opinion clients of De Brauw.

(c)    FCA may:

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

(ii)    refer to De Brauw giving this opinion under the heading ''Legal Matters'' in the prospectus included 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 in that paragraph is required under Section 7 of the Securities Act or any rules or regulations of the SEC promulgated under it.

Yours faithfully,
De Brauw Blackstone Westbroek N.V.
