CORRIGENDUM TO THE ANNOUNCEMENT ON THE FULL YEAR RESULTS OF THE COMPANY

This is with reference to our announcement dated 23 February 2012 that was release on the same date.

We wish to clarify that on page 16, under "Gross profit", the first paragraph should be read as follows:

"Gross Profit
The $86.9 million decrease in gross profit was primarily contributed by the shipbuilding, ship repair and conversion segment as a result of (1) the reduction in external revenue; (2) non-capitalisable costs of shipyard relating to construction of vessels for the chartering fleet with no corresponding revenue; and (3) the reversal of profits arising from the cancellation of two vessels (disclosed in the Q3-2011 announcement) and expected cancellation ofanother vessel. The reversal of profits amounted to $32.9 million (FY2010: $23.6 million). This decrease was exacerbated by reduction in leasing revenue and lower utilisation rates of vessels in the geophysical segment."
The words that are underlined have been added. We confirm there is no change in the gross profit of the Company..
