Schedule 2

QUALIFICATIONS

The opinions in this opinion letter are subject to the following qualifications:

1 Insolvency

The opinions expressed herein may be affected or limited by the provisions of any applicable bankruptcy, suspension of payments, any intervention, recovery or resolution measure, other insolvency proceedings and fraudulent conveyance (actio Pauliana) and other laws of general application now or hereafter in effect, relating to or affecting the enforcement or protection of creditors’ rights.

2 Enforceability

2.1 The opinions expressed herein, with respect to a Deed of Issuance, may be affected by the availability of general defences under Dutch law such as the principles of reasonableness and fairness, modification on grounds of unforeseen circumstances, duress, deceit, mistake, undue influence and, if and to the extent not validly waived, force majeure, the right to suspend performance as long as the other party is in default in respect of its obligations, the right to set-off and the right to dissolve a transaction upon default by the other party.

2.2 A Dutch legal entity may invoke the nullity of a transaction if the transaction does not fall within the objects of such legal entity and the other parties to the transaction knew, or without independent investigation, should have known, that such objects were exceeded. In determining whether a transaction falls within the objects of a legal entity all relevant circumstances should be taken into account, including the wording of the objects clause of the articles of association and the level of (direct or indirect) benefit derived by the legal entity.

3 Non-assessable

Non-assessable has no equivalent legal term under Dutch law, but is interpreted to express that the shareholders cannot be required to make any further payments on their fully paid-up Shares.
