Nostrum withdraws its proposed offer for Tethys

Nostrum Oil & Gas PLC (LSE: NOG) ("Nostrum" or the "Company"), an independent oil and gas company engaging in the production, development and exploration of oil and gas in the pre-Caspian Basin, announces that it has withdrawn its proposed offer that was previously announced on 23 September 2015 (the "Proposed Offer") to acquire the entire issued share capital of Tethys Petroleum Limited ("Tethys") together with a proposed US $20 million interim funding to Tethys (the "Interim Funding" and, together with the Proposed Offer, the "Proposed Transaction").

Nostrum and Tethys have worked together to negotiate legally binding agreements implementing the Proposed Transaction during an exclusivity period that began on 23 September 2015 and expired at 11:59 p.m. on 6 October 2015. However, as stated in Nostrum's announcement of 23 September 2015 it is a condition to entry into those agreements that the three major shareholders of Tethys agree to support the Proposed Offer in form and substance satisfactory to Nostrum. Tethys' largest shareholder, Pope Asset Management LLC, has informed Nostrum that it does not support the Proposed Offer and therefore, despite the progress made by Nostrum and Tethys in preparing transaction documentation, the Proposed Transaction will not proceed.

Nostrum reserves the right to propose alternative transactions to Tethys and/or to make an offer for the share capital of Tethys on different terms to those previously announced.
