Executive Summary - Continued

www.bayan.com.sg

2012 Coal Production was 16.3 million MT which was within the range of the

Revised Guidance although growth was lower than anticipated due to the weak

market condition

2012 Cash costs (include COGS, Royalties, and SGA) was US$ 78.1 / MT which

was lower than the range of the Revised Budget but higher than 2011 Cash Costs

at US$74.7 / MT due to higher standard strip ratio in the first half of 2012 as a

result of pit optimization at certain sites.

2012 Coal Sales volume was 16.0 million MT which was within the range of the

Revised Budget but the increase in volume was lower than expected due to the

following :

Underperformance of BUMA at PIK Temporary suspension of coal mining at GBP Lower barging at FSP/BT due to lower river levels
