Vantage Proposes Senior Notes Offer

Vantage announced that its wholly-owned subsidiary Offshore Group Investment Limited (the "Issuer") intends to offer, subject to market and other conditions, $225.0 million in aggregate principal amount of 11 ½% Senior Secured First Lien Notes due 2015. The Notes will be offered as additional notes, commonly referred to as a "tack-on bond," under the indenture pursuant to which the Issuer previously issued $1.0 billion of 11 ½% Senior Secured First Lien Notes due 2015 in July 2010. The Notes will be guaranteed by Vantage and each of Issuer's existing and future subsidiaries and by certain of Vantage's other subsidiaries, and will be senior secured obligations of the Issuer and the guarantors.

The Issuer expects to use the net proceeds from this offering, if completed, to purchase from Vantage the wholly-owned subsidiaries of Vantage which own the Aquamarine Driller and related drilling contracts (the "Acquisition"), as well as for general corporate purposes. Vantage expects to use the proceeds from the Acquisition to (i) repay and terminate its outstanding term loan secured by the Aquamarine Driller, (ii) make the initial payment to Daewoo Shipbuilding and Marine Engineering Co., Ltd under Vantage's recently announced construction contract for an ultra-deepwater drillship, to be named the Tungsten Explorer and (iii) for general corporate purposes.
