Messrs

Vantage Drilling International

777 Post Oak Boulevard, Suite 800

Houston, Texas 77056,

Dear Sirs,

1.	Background

1.1

We have acted as Cyprus counsels of Vantage Holdings Cyprus ODC Limited, a company incorporated in the Republic of Cyprus, with registration number HE 288980, whose registered office is at Themistokli Dervi 17 - 19, THE CITY HOUSE, 1066 Nicosia, Cyprus (the ‘‘Company’’), and Vantage Drilling International (formerly known as Offshore Group Investments Limited) (“VDI”) in connection with the 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 the sale by the selling security holders identified in the prospectus (the “Selling Securityholders”) from time to time of up to 2,550,682 units of stapled securities (the “Stapled Securities”) of VDI. Each Stapled Security comprises one ordinary share of VDI, par value $0.001 per share (the “Common Shares”), and $172.61 original issuance principal amount of VID’s 1% / 12% Step-Up Senior Secured Third Lien Convertible Notes due 2030 (the “Notes”), in each case subject to adjustment as described in the Indenture (as defined below). The Notes were issued under a third lien indenture, dated 10 February 2016 (as supplemented, the “Indenture”), among VDI, the guarantors named therein, including without limitation the Company (collectively the “Guarantors”) and U.S. Bank National Association as trustee and collateral agent (together with its successors and assigns, in such capacity, the “Noteholder Collateral Agent”). Pursuant to the terms and conditions of the Indenture the Notes are guaranteed by the Guarantors.
