| 2 | Assumptions |
The following opinions are given only as to, and based on, circumstances and matters of fact existing and known to us on the date of this opinion letter. These opinions only relate to the laws of the British Virgin Islands which are in force on the date of this opinion letter. In giving the following opinions we have relied (without further verification) upon the completeness and accuracy, as at the date of this opinion letter, of the Registry List of Directors, the Registered Agent’s Certificate, the Certificate of Good Standing and the Director’s Certificate. We have also relied upon the following assumptions, which we have not independently verified:
| 2.1 | The Documents have been or will be authorised and duly executed and unconditionally delivered by or on behalf of all relevant parties in accordance with all relevant laws (other than, with respect to the Company, the laws of the British Virgin Islands). |
| 2.2 | The Documents are, or will be, legal, valid, binding and enforceable against all relevant parties in accordance with their terms under the laws of the State of New York in the case of the Purchase Agreements and the laws of Greenland in the case of the Heads of Agreement and the 60̊ North Agreement (such laws, as applicable, the “Relevant Law”) and all other relevant laws (other than, with respect to the Company, the laws of the British Virgin Islands). |
2
| 2.3 | The choice of the Relevant Law as the governing law of the Documents has been made in good faith and would be regarded as a valid and binding selection which will be upheld by the courts of the State of New York in relation to the Purchase Agreements and the courts of Greenland in relation to the Heads of Agreement and the 60̊ North Agreement and any other relevant jurisdiction (other than the British Virgin Islands) as a matter of the Relevant Law and all other relevant laws (other than the laws of the British Virgin Islands). |
| 2.4 | Where a Document has been provided to us in draft or undated form, it will be duly executed, dated (where required to be dated) and unconditionally delivered by all parties thereto in materially the same form as the last version provided to us and, where we have been provided with successive drafts of a Document marked to show changes to a previous draft, all such changes have been accurately marked. |
| 2.5 | Copies of documents, conformed copies or drafts of documents provided to us are true and complete copies of, or in the final forms of, the originals. |
| 2.6 | All signatures, initials and seals are genuine. |
| 2.7 | The capacity, power, authority and legal right of all parties under all relevant laws and regulations (other than, with respect to the Company, the laws and regulations of the British Virgin Islands) to enter into, execute, unconditionally deliver and perform their respective obligations under the Documents. |
| 2.8 | That all public records of the Company which we have examined are accurate and that the information disclosed by the searches which we conducted against the Company at the Registry of Corporate Affairs and the High Court Registry is true and complete and that such information has not since then been altered and that such searches did not fail to disclose any information which had been delivered for registration but did not appear on the public records at the date of our searches. |
| 2.9 | The Memorandum and Articles remain in full force and effect and are unamended and that the Company had or will have sufficient authorised and unissued shares under the Memorandum and Articles at the time any of the Ordinary Shares were or are issued. |
| 2.10 | The Resolutions were each signed by all the directors in the manner prescribed in the Memorandum and Articles, including as to the disclosure of any director’s interests, and have not been amended, varied or revoked in any respect. |
| 2.11 | The members of the Company (the “Members”) have not restricted or limited the powers of the directors of the Company in any way. |
| 2.12 | No invitation has been or will be made by or on behalf of the Company to the public in the British Virgin Islands to subscribe for any of the Ordinary Shares. |
| 2.13 | The Ordinary Shares issued or to be issued pursuant to the Documents have been, or will be, duly registered, and will continue to be registered, in the Company’s register of members. |
3
| 2.14 | The Company has received, or will receive, cash consideration or non-cash consideration in consideration for the issue of the Ordinary Shares pursuant to the Documents, and that: |
| (a) | none of the Ordinary Shares have been, or will be, issued for less than their par value; and |
| (b) | to the extent that any Ordinary Shares have been, or will be, issued, in whole or in part, for non-cash consideration, the value of the non-cash consideration and cash consideration, if any, is not less than the amount credited or to be credited for such Ordinary Shares. |
| 2.15 | There is nothing under any law (other than the laws of the British Virgin Islands) which would or might affect the opinions set out below. |
Save as aforesaid we have not been instructed to undertake and have not undertaken any further enquiry or due diligence in relation to the transaction the subject of this opinion.
| 3 | Opinions |
Based upon, and subject to, the foregoing assumptions and the qualifications set out below, and having regard to such legal considerations as we deem relevant, we are of the opinion that:
| 3.1 | The Company is a company limited by shares incorporated with limited liability under the BVI Business Companies Act (As Revised) (the “Act”), is in good standing at the Registry of Corporate Affairs and is validly existing under the laws of the British Virgin Islands. |
| 3.2 | The Ordinary Shares issued pursuant to the Documents held by the applicable Selling Securityholder to be resold as contemplated by the Registration Statement were duly authorised, and when issued and paid for in the manner described in the Documents and in accordance with the Resolutions, such Ordinary Shares were legally issued, fully paid and non-assessable. As a matter of British Virgin Islands law, a share is only issued when it has been entered in the register of members of the Company. |
| 4 | Qualifications |
The opinions expressed above are subject to the following qualifications:
| 4.1 | To maintain the Company in good standing with the Registrar of Corporate Affairs under the laws of the British Virgin Islands, annual filing fees must be paid, and certain statutory filings and returns made to the Registrar of Corporate Affairs within the time frame prescribed by law. As a consequence of a failure to pay annual filing fees, or to make certain filings or returns, on time, or to demonstrate compliance with certain statutory economic substance requirements where relevant, the Company may be liable to be struck off the register of companies and dissolved. |
| 4.2 | We express no view as to the commercial terms of the Documents or whether such terms represent the intentions of the parties and we make no comment with respect to any representations and warranties which may be made by or with respect to the Company in any of the documents or instruments cited in this opinion or otherwise with respect to the commercial terms of the transactions the subject of this opinion. |
4
| 4.3 | Under British Virgin Islands law, the register of members is prima facie evidence of title to shares and this register would not record a third party interest in such shares. However, there are certain limited circumstances where an application may be made to a British Virgin Islands court for a determination on whether the register of members reflects the correct legal position. Further, the British Virgin Islands court has the power to order that the register of members maintained by a company should be rectified where it considers that the register of members does not reflect the correct legal position. For the purposes of the opinion given in paragraph 3.2, there are no circumstances or matters of fact known to us on the date of this opinion letter which would properly form the basis for an application for an order for rectification of the register of members of the Company, but if such an application were made in respect of the Ordinary Shares, then the validity of such shares may be subject to re-examination by a British Virgin Islands court. |
| 4.4 | Except as specifically stated herein, we make no comment with respect to any representations and warranties which may be made by or with respect to the Company in any of the documents or instruments cited in this opinion or otherwise with respect to the commercial terms of the transactions the subject of this opinion. |
| 4.5 | In this opinion letter, the phrase “non-assessable” means, with respect to the issuance of shares, that a shareholder shall not, in respect of the relevant shares and in the absence of a contractual arrangement, or an obligation pursuant to the memorandum and articles of association, to the contrary, have any obligation to make further contributions to the Company’s assets (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil). |
| 4.6 | The search of records of proceedings available at the High Court Registry would not reveal any proceeding which has been placed under seal or anonymised (whether by order of the Court or pursuant to the practice of the High Court Registry). |
We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our firm under the heading “Legal Matters” in the Registration Statement. In providing our consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the SEC Act or the rules and regulations of the Commission thereunder.
This opinion is addressed to you and may be relied upon by you, your counsel and purchasers of Shares pursuant to the Registration Statement. This opinion is limited to the matters detailed herein and is not to be read as an opinion with respect to any other matter.
Yours faithfully
