Vantage Drilling Announces Consent Solicitation by Its Subsidiary Offshore Group Investment Limited in Connection With 11 1/2% Senior Secured First Lien Notes Due 2015 (CUSIP No. 676253 AC1)


HOUSTON, TX--(Marketwire - May 11, 2011) - Vantage Drilling Company (the "Company") (NYSE Amex: VTG.U) (NYSE Amex: VTG) (NYSE Amex: VTG.WS) announced today that its wholly-owned subsidiary Offshore Group Investment Limited (the "Issuer") has commenced a solicitation of consents (the "Consent Solicitation") from holders of its 11 ½% Senior Secured First Lien Notes due 2015 (the "Notes").

The Consent Solicitation will expire at 5:00 p.m., New York City time, on May 19, 2011, unless otherwise extended (such time and date, as may be extended, the "Expiration Date"). A consent can be revoked prior to the earlier of the receipt of the Requisite Consents or the Expiration Date (such time and date, as may be extended, the "Revocation Deadline"). Adoption of the proposed amendments requires the receipt of valid and unrevoked consents from holders of more than a majority in aggregate principal amount of the Notes (other than any Notes owned by the Company or any of its affiliates) (the "Requisite Consents").

Subject to the terms and conditions of the Consent Solicitation, the Issuer expects to pay, on the closing date to each holder of Notes that consents to the proposed amendments, on or prior to the Expiration Date, a fee equal to $5 in cash for each $1,000 in principal amount of the Notes (the "Consent Fee"). Payment of the Consent Fee is conditioned on the receipt of the Requisite Consents, among other things.

The purpose of the Consent Solicitation is to obtain approval to amend the indenture governing the Notes and the related security agreement. The proposed amendments would (i) permit the Issuer to issue up to an additional $225.0 million aggregate principal amount of Notes (the "Additional Notes"), the proceeds of which would be used to purchase from the Company all of the equity interests of P2020 Rig Co., the entity that owns the Aquamarine Driller, a jack-up drilling rig, and the related purchase of the subsidiary of the Company that is the party to the drilling contract for the Aquamarine Driller (together, the "Acquisitions"), (ii) permit the Company to consummate the Acquisitions under the indenture, (iii) permit the Company to issue, from time to time, up to $125.0 million aggregate principal amount of convertible debt, convertible into the Company's ordinary shares and (iv) modifying the Issuer's restrictions on maintaining funds in foreign deposit accounts. The Company expects to use a portion of the proceeds from the Acquisitions to repay and terminate its Term Loan Facility Agreement dated August 26, 2009 which was originally used to fund a portion of the construction cost of the Aquamarine Driller. The remainder of the proceeds is expected to be used by the Company to make the initial payment to Daewoo Shipbuilding and Marine Engineering Co., Ltd under the Company's recently announced construction contract for an ultra-deepwater drillship, and for general corporate purposes.

The Consent Solicitation is being made pursuant to a Consent Solicitation Statement, dated May 11, 2011, and a related Letter of Consent.
