Placing

PetroNeft has agreed the terms of a conditional placing of 216,052,348 new Ordinary Shares at Stg£0.05 (€0.06) per Ordinary Share (the "Placing Shares"), raising gross proceeds of approximately US$17.25million (the "Placing").

The Placing is being executed in two tranches and has been arranged by Davy and Canaccord Genuity. The first tranche of the Placing consists of a conditional placing of 41,635,643 Ordinary Shares (the ''First Tranche Placing Shares") which is conditional, inter alia, on admission of such Ordinary Shares to trading on the AIM Market of the London Stock Exchange ("AIM") and the ESM Market of the Irish Stock Exchange ("ESM"). The second tranche of the Placing (the "Second Tranche Placing") consists of a conditional placing of 174,416,705 Ordinary Shares (the ''Second Tranche Placing Shares") which is conditional, inter alia, on admission of such Ordinary Shares to trading on AIM and ESM and upon receiving shareholder approval at an extraordinary general meeting of the Company to be held on 19 November 2012 ("EGM"). A circular to convene the EGM will be sent to shareholders shortly.

US$7.5 million will be used in part repayment of the existing Macquarie loan facility with the balance to be used to finance the continuation of the 2012-2013 Arbuzovskoye development programme, working capitaland transaction costs.

Directors' and Management participation in the Placing

Certain Directors and management of PetroNeft will subscribe for the following Placing Shares:

Licence 61 - Arbuzovskoye Development Programme

As announced on 22 October 2012, Arbuzovskoye well 102, the second of ten planned new production wells on the Arbuzovskoye oil field, was successfully completed and brought into production at an initial rate of 540 bopd with less than 2% water cut. This production rate was well above the Company's target rate and further confirms the excellent continuity and good reservoir properties in the eastern portion of the Arbuzovskoye field.

Development will continue with a further eight new production wells planned for the current development programme. Arbuzovskoye well 109, the next well in the drilling sequence, is currently drilling ahead. It is anticipated that the completion of development programme will be funded from operating cashflows and a portion of the proceeds of the Placing.

Arbuzovskoye contains 2P reserves in excess of 13 million barrels of oil according to independent reserve auditors Ryder Scott and is the Company's second production development.

Macquarie Debt Facility

The Company and Macquarie have agreed to amend the Company's existing US$30 million borrowing base loan facility. The amendments to the facility include the repayment of US$7.5 million from the proceeds of the Placing, the repayment of a further US$9.1 million in fourteen monthly instalments ($650,000 per month) beginning on 31 March 2013 and the conversion of US$1 million of debt into equity in the Company at the placing price of Stg£0.05 per share (the "Macquarie Shares"). In addition, production covenants will be removed and Macquarie will waive the right to seek additional repayments of the outstanding balance at the next three reviews which were due to take place on 31 December 2012, 30 June 2013 and 31 December 2013. Macquarie will continue to hold US$4 million in a Debt Service Reserve Account ("DSRA") until the maturity of the loan. The final outstanding balance of US$12.4 million (US$8.4 million net of the DSRA) will be repaid in a lump sum at the maturity of the facility in May 2014. These proposed amendments and the conversion are subject to, amongst other things, the preparation and execution of formal documentation, and the completion of the Placing. The amended facility will be subject to certain financial covenants and lender approvals for the application of certain funds typical of a facility of this nature.

In May 2012, PetroNeft entered into a three year loan facility for US$15 million with its partner Arawak Energy. This loan facility will be unaffected by the above amendments.

Corporate Development

Positioning the Company so that it can fully exploit the opportunities available to it is of crucial importance. To this end, the Company continues in active discussions with a number of parties about possible farm-outs which, in the long term, should strengthen the Company's financial position and position the Company to extract value from its reserve base and to pursue opportunities.

Dennis Francis, Chief Executive Officer of PetroNeft Resources plc commented:

"We are pleased with the outcome of the Placing and the high level of support received from both new and existing institutional shareholders. The combination of the results of recent Arbuzovskoye wells and stable financing base will allow management to continue to focus on materially increasing our production profile and cash flows, substantially increase the value of our reserve base and focus on the numerous corporate development opportunities available to us."

Application will be made to the London Stock Exchange and the Irish Stock Exchange for the First Tranche Placing Shares to be admitted to trading on AIM and ESM, with Admission of the First Tranche Placing Shares expected to occur on 30 October 2012. Application will also be made for the Admission of the Second Tranche Placing Shares and the Macquarie Shares to trading on AIM and ESM, with admission of the Second Tranche Placing Shares and the Macquarie Shares expected on 20 November 2012, subject to the approval of the Second Tranche Placing by the Company's shareholders at the EGM. The Placing Shares will, when issued, rank pari passu in all respects with the existing Ordinary Shares including the right to receive dividends and other distributions declared following Admission.
