ITEM 1.01 Entry into a Material Definitive Agreement.

On April 16, 2014, Samson Oil & Gas Limited (“Samson” or the “Company”) (ASX: SSN; NYSE MKT: SSN) entered into Subscription Agreements (the “Subscription Agreements”) with certain investors identified on the signature pages thereto. Pursuant to the Subscription Agreements, Samson placed 290,110,820 ordinary shares (which may be represented by American Depositary Shares, or ADSs) and 87,033,246 warrants to purchase 87,033,246 ordinary shares with investors based in the United States and Australia, raising gross proceeds of US$5,439,578 (before subtracting the placement agents’ fees). The placement was completed at A$0.02 per ordinary share (approximately US$0.375 per ADS), and includes options, or warrants, to purchase an additional 3 shares for every 10 shares subscribed for, at an exercise price of A$0.033 (approximately US$0.61 per ADS). The options/warrants expire on April 30, 2018 and will not be separately listed on the ASX.

Conversion from Australian Dollars to US dollars is based on an exchange rate on April 11, 2014 of A$1.00 per US$0.9375 from the Reserve Bank of Australia.

All of the ordinary shares and ADSs were offered and sold pursuant to an effective shelf registration statement on Form S-3, as amended (Registration No. 333-183327) and a prospectus supplement filed with the SEC in preliminary form on April 15, 2014 and in final form on April 17, 2014.
