	Schedule 3
	Reservations
Our opinion is subject to the following:
1.	Currency of Court Judgments: The Cayman Islands Grand Court Rules 1995 expressly contemplate that judgments may be granted by the Grand Court of the Cayman Islands in currencies other than Cayman Islands dollars or United States dollars. Such Rules provide for various specific rates of interest payable upon judgment debts according to the currency of the judgment.
2.	Conversion of Debts: In the event the Company is placed into liquidation, the Cayman Islands court is likely to require that all debts are converted (at the official exchange rate at the date of conversion) into and paid in a common currency which is likely to be Cayman Islands dollars or United States dollars.
3.	Summary Court Register: We have not examined the register of the summary court of the Cayman Islands on the basis that claims in such court are limited to a maximum of approximately USD24,000.
4.	Preferences: Every conveyance or transfer of property, or charge thereon, and every payment obligation and judicial proceeding, made, incurred, taken or suffered by a company at a time when that company was unable to pay its debts within the meaning of section 93 of the Companies Act, and made or granted in favour of a creditor with a view to giving that creditor a preference over the other creditors of the Company, would be invalid pursuant to section 145(1) of the Companies Act, if made, incurred, taken or suffered within the six months preceding the commencement of a liquidation of the Company. Such actions will be deemed to have been made with a view to giving such creditor a preference if it is a “related party” of the Company. A creditor shall be treated as a related party if it has the ability to control a company or exercise significant influence over a company in making financial and operating decisions.
5.	Undervalues: Any disposition of property made at an undervalue by or on behalf of a company and with an intent to defraud its creditors (which means an intention to wilfully defeat an obligation owed to a creditor), shall be voidable (i) under section 146 of the Companies Act at the instance of the company’s official liquidator, and (ii) under the Fraudulent Dispositions Act, at the instance of a creditor thereby prejudiced.

6.	Defrauding Creditors: If any business of a company has been carried on with intent to defraud creditors of the company or creditors of any other person or for any fraudulent purpose, the Cayman Islands court may declare that any persons who were knowingly parties to the carrying on of the business of the company in such manner are liable to make such contributions, if any, to the company’s assets as the court thinks proper.
7.	Good Standing: Our opinion as to good standing is based solely upon receipt of the Certificate of Good Standing issued by the Registrar of Companies. The Company shall be deemed to be in good standing under section 200A of the Companies Act on the date of issue of the certificate if all fees and penalties under the Companies Act have been paid and the Registrar of Companies has no knowledge that the Company is in default under the Companies Act.
8.	Corporate Documents: The Registry of Companies in the Cayman Islands is not public in the sense that copies of the Constitutional Documents and information on shareholders is not publicly available and information on directors is limited. We have therefore obtained scanned copies of the corporate documents specified in Schedule 1 and relied exclusively on such scanned copies for the verification of such corporate information.
9.	Issue of shares: Based on the decision in the English case of Houldsworth v City of Glasgow Bank (1880) 5 App Cas 317 HL, in the event of a misrepresentation by a Company on which a shareholder relied in agreeing to subscribe for shares in such Company, the shareholder may be entitled to rescind the share subscription agreement and thereafter claim damages against such Company for any additional loss suffered as a result of the misrepresentation. Such a claim for damages will not arise unless and until the shareholder has successfully rescinded the share subscription agreement. A shareholder may be barred from rescinding on the grounds of delay or affirmation and if such Company is wound up (whether voluntarily or compulsorily), such shareholder will lose the right to rescind the share subscription agreement.
