Confirmation of Suspension of Listing of Nostrum Oil & Gas LP’s GDRs and of the Scheme Record Time and Approval of the Admission of the Shares of Nostrum Oil & Gas plc to the Kazakhstan Stock Exchange

The Directors of Nostrum Oil & Gas LP (the “Partnership”), a London listed multi-field E&P business with assets in the northern part of the oil-rich pre-Caspian basin, are pleased to confirm certain details in connection with the proposed scheme of reorganisation of the Partnership’s group (the “Scheme”) as set out below. Further details relating to the Scheme are set out in the scheme circular published on 20 May 2014 by the Partnership (the “Scheme Circular”) which is available on the Partnership’s website: www.nostrumoilandgas.com. Capitalised terms used in this announcement and not otherwise defined herein have the same meanings given to them in the Scheme Circular:

1.         Suspension of the GDR Listing

In order to determine the list of holders of Common Units and GDRs who will be entitled to receive the New Shares as part of the Scheme, the Partnership has applied to the FCA and the London Stock Exchange to suspend the GDR Listing in accordance with the Listing Rules and the Admission and Disclosure Standards with effect from close of trading on the London Stock Exchange three trading days prior to the Scheme Record Date.  This suspension is intended to ensure that all transfers of GDRs via the London Stock Exchange prior to such suspension are appropriately reflected in the register of holders of the GDRs prior to the Scheme Record Time.

The Partnership confirms that the suspension of the GDR Listing will be effective from 7.30 a.m. on 13 June 2014.

Following such suspension, GDR Holders will able to transfer or otherwise dispose of their interests in GDRs but will not be able to effect transfers of their GDRs via the London Stock Exchange.  Holders of GDRs should be aware that any transfers of GDRs after the suspension of trading of the GDRs on the London Stock Exchange may not provide sufficient time for such transfers to be appropriately reflected in the register of holders of the GDRs prior to the Scheme Record Time and thereby ensure their entitlement to the receipt of New Shares. The suspension will last for five business days to allow the register of holders of GDRs to be updated, to allow the Partnership to implement the Scheme, to effect the Reorganisation and to obtain the remaining regulatory consents, before dealings in the New Shares are expected to commence on the second business day following the Scheme becoming effective.

2.         Scheme Record Time

The Partnership confirms that the Scheme Record Time will be 5.00 p.m. on 17 June 2014.

Following the Scheme Record Time, no transfer, sale or disposal of any Common Unit will be permitted.

3.         KASE Admission

The Directors of the Partnership are also pleased to announce that the admission to listing on the Kazakhstan Stock Exchange (the “KASE”) of the ordinary share capital of Nostrum Oil & Gas plc (the “Company”) has been approved by the KASE and that such admission became effective on 10 June 2014.

4.         Timetable to Admission

Following the implementation of the Scheme, the Company will become the new holding company of the Partnership’s Group.  It is expected that the Company’s ordinary share capital will be admitted to the premium listing segment of the Official List of the Financial Conduct Authority and to trading on the Main Market of the London Stock Exchange on 20 June 2014.  The Annex to this announcement re-confirms the timetable to admission, as outlined in the Scheme Circular.
