Dear Sirs

Vantage Drilling International

We have acted as Cayman Islands counsel to Vantage Drilling International (“VDI”) in connection with VDI’s registration statement (the “Registration Statement”) on Form S-1, including all amendments or supplements thereto, filed with the United States Securities and Exchange Commission (the “Commission”) under the United States Securities Act of 1933, as amended, (the “Act”) relating to (i) up to 2,550,682 stapled securities (the “Units”), each Unit consisting of one ordinary share of VDI, par value US$0.001 per share (each a “Share” and together, the “Shares”), and US$172.61 original aggregate principal amount of 1%/12% Step-Up Senior Secured Third Lien Convertible Notes due 2030 (each a “Note” and together, the “Notes”) issued pursuant to the Third Lien Indenture dated as of 10 February 2016 by and among VDI, unconditionally and irrevocably guaranteed by, amongst others, Emerald Driller Company (“Emerald”), Sapphire Driller Company (“Sapphire”), P2021 Rig Co. (“P2021”), Vantage Driller I Co. (“Vantage Driller I”), Vantage Driller II Co. (“Vantage Driller II”), Vantage Driller III Co. (“Vantage Driller III”) Vantage Driller IV Co. (“Vantage Driller IV”), Vantage Driller VI Co. (“Vantage Driller VI”), Vantage International Management Co. (“VIMCO”), P2020 Rig Co. (“P2020”), Vantage Holdings Malaysia I Co. (“Malaysia I”), Dragonquest Holdings Company (“Dragonquest”), Vantage Deepwater Company (“Deepwater”) and Vantage Drilling Africa (“Vantage Africa”), for which we also act as Cayman Islands counsel (the “Guarantors”, and each of the foregoing including VDI, a “Company” and together, the “Companies”) and U.S. Bank National Association, as trustee and third lien noteholder collateral agent substantially in the form incorporated by reference as an Exhibit to the Registration Statement (as amended and/or supplemented by a supplemental indenture dated 8 June 2016, the “Indenture”), (ii) all Shares that may be issued upon the conversion of the Notes into Shares pursuant to the Indenture; and (iii) 655,094 Shares that are not part of the Units (the “Vantage Shares”).

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. These opinions only relate to the laws of the Cayman Islands which are in force on the date of this opinion. In giving these opinions we have relied (without further verification) upon the completeness and accuracy and confirmations contained in the Certificates of Good Standing. We have also relied upon the following assumptions, which we have not independently verified:

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.

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:

As a matter of Cayman Islands law, a share is only issued when it has been entered in the register of members (shareholders) of the relevant company. Under Cayman Islands law, the register of members (shareholders) 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 Cayman Islands court for a determination on whether the register of members reflects the correct legal position. Further, the Cayman 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. As far as we are aware, such applications are rarely made in the Cayman Islands, but if this were to occur in respect of VDI’s Shares, then the validity of such shares may be subject to re-examination by a Cayman Islands court.

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 Companies 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.

In this opinion, the phrase “non-assessable” means, with respect to the Shares in VDI, that a shareholder shall not, solely by virtue of its status as a shareholder, be liable for additional assessments or calls on the Shares by VDI 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).

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 prospectus included in the Registration

6

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 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.
