Schedule 3

Qualifications

Good Standing

1 Under the Companies Act (Revised) of the Cayman Islands annual returns in respect of the Company must be filed with the Registrar, together with payment of annual filing fees. A failure to file annual returns and pay annual filing fees may result in the Company being struck off the Register of Companies, following which its assets will vest in the Financial Secretary of the Cayman Islands and will be subject to disposition or retention for the benefit of the public of the Cayman Islands.

2 In good standing means only that as of the date of the Good Standing Certificate the Company is up-to-date with the filing of its annual returns and payment of annual fees with the Registrar. We have made no enquiries into the Company's good standing with respect to any filings or payment of fees, or both, that it may be required to make under the laws of the Cayman Islands other than the Companies Act.

Limited liability

3 We are not aware of any Cayman Islands authority as to when the courts would set aside the limited liability of a shareholder in a Cayman Islands company. Our opinion on the subject is based on the Companies Act of the Cayman Islands and English common law authorities, the latter of which are persuasive but not binding in the courts of the Cayman Islands. Under English authorities, circumstances in which a court would attribute personal liability to a shareholder are very limited, and include: (a) such shareholder expressly assuming direct liability (such as a guarantee); (b) the company acting as the agent of such shareholder; (c) the company being incorporated by or at the behest of such shareholder for the purpose of committing or furthering such shareholder’s fraud, or for a sham transaction otherwise carried out by such shareholder. In the absence of these circumstances, we are of the opinion that a Cayman Islands’ court would have no grounds to set aside the limited liability of a shareholder.

Non-Assessable

4 In this opinion letter, the phrase “non-assessable” means, with respect to the Ordinary Shares in the Company, that a shareholder shall not, solely by virtue of its status as a shareholder, be liable for additional assessments or calls on the Ordinary Shares by the Company or its creditors (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstance in which a court may be prepared to pierce or lift the corporate veil).

8

Register of Writs

5 Our examination of the Register of Writs cannot conclusively reveal whether or not there is:

(a) any current or pending litigation in the Cayman Islands against the Company; or

(b) any application for the winding up or dissolution of the Company or the appointment of any liquidator or trustee in bankruptcy in respect of the Company or any of its assets,

as notice of these matters might not be entered on the Register of Writs immediately or updated expeditiously or the court file associated with the matter or the matter itself may not be publicly available (for example, due to sealing orders having been made). Furthermore, we have not conducted a search of the summary court. Claims in the summary court are limited to a maximum of CI $20,000.

Enforceability

6 In this opinion, the term “enforceable” means that the relevant obligations are of a type that the courts of the Cayman Islands will ordinarily enforce, but it does not mean that those obligations will necessarily be enforced in all circumstances in accordance with their terms. In particular, but without limitation:

(a) enforcement may be limited by insolvency or similar laws affecting the rights of creditors;

(b) enforcement may be limited by general principles of equity. In particular, equitable remedies, such as specific performance and injunction, will only be granted by a court in its discretion and may not be available where the court considers damages to be an adequate remedy;

(c) a claim may be barred by statutes of limitation, or it may be or become subject to defences of set-off, abatement, laches or counterclaim and the doctrines of estoppel, waiver, election, forbearance or abandonment;

(d) a court may refuse to allow unjust enrichment;

(e) a person who is not a party to a Document that is governed by Cayman Islands law may not have the benefit of and may not be able to enforce its terms except to the extent that the relevant Document expressly provides that the third party may, in its own right, enforce such rights (subject to and in accordance with the Contracts (Rights of Third Parties) Act, 2014;

(f) enforcement of an obligation of a party under a Document may be invalidated or vitiated by reason of fraud, duress, misrepresentation or undue influence or it may be limited by Cayman Islands law dealing with frustration of contracts;

(g) a provision of a Document that fetters any statutory power of a Cayman Islands’ company, such as a provision restricting the company’s power to commence its winding up, to alter its memorandum and articles of association or to increase its share capital, may not be enforceable;

9

(h) the effectiveness of a provision in a Document releasing a party from a liability or duty otherwise owed may be limited by law;

(i) a court will not enforce a provision of a Document to the extent that it may be illegal or contrary to public policy in the Cayman Islands or purports to bar a party unconditionally from, seeking any relief from the courts of the Cayman Islands or any other court or tribunal chosen by the parties;

(j) a provision of a Document that is construed as being penal in nature, in that it provides that a breach of a primary obligation results in a secondary obligation that imposes a detriment on the contract-breaker out of all proportion to any legitimate interest of the innocent party in the enforcement of the primary obligation, will not be enforceable (and we express no opinion as to whether such a provision is proportionate);

(k) a court may refuse to give effect to a provision in a Document (including a provision that relates to contractual interest on a judgment debt) that it considers usurious;

(l) a court may not enforce a provision of a Document to the extent that the transactions contemplated by it contravene economic or other sanctions imposed in respect of certain states or jurisdictions by a treaty, law, order or regulation applicable to the Cayman Islands;

(m) a court may refuse to give effect to a provision in a Document that involves the enforcement of any foreign revenue or penal laws;

(n) where a contract provides for the payment of legal fees and expenses incurred by a party to that contract in enforcing the contract, a party who succeeds in enforcing the contract is entitled to recover by court judgment the amount of the legal fees and expenses found to be due under the terms of the contract. In all other cases, costs of legal proceedings can only be recovered from another party to the proceedings by a court order, which is a matter for the discretion of the court, and such costs are liable to taxation (assessment by the court); and

(o) enforcement may be prohibited or otherwise prejudiced if a Relevant Interest is subject to a Restrictions Notice.

7 A court may determine in its discretion the extent of enforceability of a provision of a Document that provides for or requires, as the case may be:

(a) severability of any provision of the Documents held to be illegal or unenforceable;

(b) any calculation, determination or certificate to be conclusive or binding, including if that calculation, determination or certificate is fraudulent or manifestly inaccurate or has an unreasonable or arbitrary basis;

(c) the vesting in a party of a discretion or of a power to determine a matter in its opinion, if that discretion is exercised unreasonably or the opinion is not based on reasonable grounds; or

(d) written amendments or waivers of the Documents, if a purported amendment or waiver is effected by oral agreement or course of conduct,

and we express no opinion on any provisions of that type.

8 The law of the Cayman Islands may not recognise a difference between negligence and gross negligence.

9 Where any Document is dated “as of” a specific date, although the parties to that Document have agreed between themselves that, as a matter of contract and to the extent possible, their rights and obligations under it take effect from a date prior to the date of execution and delivery, the Document still comes into effect on the date it is actually executed and delivered. Rights of third parties under that Document also take effect from the date the Document is actually executed and delivered, rather than the “as of” date.
