Arias, Fábrega & Fábrega acted as Panamanian counsel to Natixis, in connection with a second amendment to the existing credit facility extended by a group of banks to Emerald Driller Company, Aquamarine Driller Company, and Topaz Driller Company, subsidiaries of Vantage Drilling Company of Houston, Texas. 

The Credit Agreement was originally entered into in June 2008 and provided for loans to the borrowers in the aggregate principal amount of up to US$440 million.  As a result of the amendments the principal amount under the Credit Agreement was reduced to a little over US$180 million.

The transaction involved the recordation of amendments to the already existing mortgages on the rigs Emerald Driller and Sapphire Driller.
