Progress on development of GTU3

Nostrum has concluded the main part of the procurement process in relation to GTU3. The total commitments entered in to by Nostrum in relation to procurement are approximately US$150m in line with the budget.

On Monday 28^th July Nostrum announced that the Group has entered into a contract with JSC “OGCC KazStroyService” for the construction of the third unit of the Group’s gas treatment facility for a consideration of US$150 million (the “Construction Contract”), in line with the budget for the GTU3 project. As the Contractor is an affiliate of KazStroyService Global B.V., which currently owns approximately 26.6% of the Company’s ordinary shares, the Construction Contract is a related party transaction for the purposes of the Listing Rules.  Accordingly, the Construction Contract is subject to the requirements of the Listing Rules and is conditional, inter alia, upon approval by the shareholders of the Company. The GTU3 project remains on budget to be completed for under US$500m and on time to allow for the doubling of production by the end of 2016.

Off-take agreement with Trafigura

In May 2014, Nostrum announced an agreement of condensate supplies signed with Trafigura.  Under the contract the Company plans to sell approximately 720,000 tons of gas condensate to Trafigura, one of the leading global commodities trading houses, over the next 24 months.

Current product destinations

The current export destinations for Nostrums products are concentrated around the following destinations:

• Crude oil – Finland

Kazakhstan Legal Proceedings

Below is an updated summary of recent developments in legal proceedings in Kazakhstan to which Nostrum’s wholly-owned operating subsidiary Zhaikmunai LLP (“Zhaikmunai”) is a party.

The appeal process in relation to the tax audit of Zhaikmunai for the period 2009-2011 undertaken by the Tax Authority in 2013 (referred to in the previous operational update) is ongoing. These proceedings do not affect Zhaikmunai’s ongoing operations, which continue uninterrupted.

In relation to the environmental proceedings brought against Zhaikmunai in the Uralsk Administrative Court by the West Kazakhstan Environmental Department (referred to in the previous operational update), on 30 May 2014 the West Kazakhstan Regional Administrative Court reversed the 28 February 2014 judgment of the Uralsk Administrative Court.
