This opinion is subject to the following qualifications and observations.

4.1	This opinion is subject to all laws relating to bankruptcy, dissolution, insolvency, re-organisation, liquidation, moratorium, court schemes and other laws and legal procedures of general application affecting or relating to the rights of creditors.

4.2	Any issuance of securities in the Company must be approved by the directors of the Company in accordance with the M&A.

4.3	Where a director fails, in accordance with the Companies Act, to disclose an interest in a transaction entered into by a BVI company, the transaction is voidable.

4.4	The Company Search will not reveal any document which has not been filed with the Registrar or which was filed but was not registered or did not appear on the Company’s file at the time of the Company Search.

4.5	The High Court Search will not reveal (among other things) if there are any:

(a)

proceedings or appointments that have not been filed or that have been filed but have not been recorded in the High Court’s judicial enforcement management system or that have been filed but did not appear on the High Court’s judicial enforcement management system at the time of the High Court Search;

The Insolvency Act requires a receiver appointed in respect of a BVI company (or any of its assets) to file a notice of appointment with the Registrar and (if the company is or has been a regulated person (as defined in the Insolvency Act)) with the British Virgin Islands Financial Services Commission. If the receiver fails to do so, the receiver will be guilty of an offence and liable to a fine. This does not, however, invalidate the receiver’s appointment.

4.7	Under the Companies Act, a company is of good standing if the Registrar is satisfied that it:

(a)

is listed on the register of companies maintained by the Registrar;

(b)

has paid to the Registrar all fees, annual fees and penalties due and payable;

has, where applicable, filed its annual return (as defined in the Companies Act) in accordance with section 98A of the Companies Act or it is not yet due to file its annual return; and

In particular, we express no opinion as to the meaning or effect of any foreign statutes referred to in the Registration Statement.

5.4	We assume no obligation to advise the Company (or any person we give consent to rely on this opinion) in relation to changes of fact or law that may have a bearing on the continuing accuracy of this opinion.
