Samson’s Ordinary Shares are traded on the Australian Securities Exchange under the symbol "SSN". Samson's American Depository Shares (ADSs) are traded on the New York Stock Exchange AMEX under the symbol "SSN". Each ADS represents 20 fully paid Ordinary Shares of Samson. Samson has a total of 1,996 million ordinary shares issued and outstanding (including 231 million options exercisable at AUD 1.5 cents), which would be the equivalent of 88.25 million ADSs. Accordingly, based on the NYSE AMEX closing price of US$1.70 per ADS on May 25th, 2012, the Company has a current market capitalization of approximately US$166 million. Correspondingly, based on the ASX closing price of A$0.083 on May 25th, 2012, the Company has a current market capitalization of A$164 million. The options have been valued at their closing price of A$0.071 on May 25th, 2012, and translated to US$ at the current exchange of 0.9744 for purposes of inclusion in the US$ market capitalization calculation.
