SEPLAT Petroleum Development Company Plc Offer Price of 210 pence per share and NGN 576 per share

London and Lagos: 9 April 2014: SEPLAT, an indigenous independent oil and gas company incorporated and operating in Nigeria with a strategic focus on Nigeria, announces the pricing of its initial public offering (the "Global Offer") and its intention to publish, later today, its Prospectus.

Upon listing, SEPLAT will be the first Nigerian company to have its ordinary shares listed on both the LSE and the

NSE.

The Offer Price has been set at 210 pence per Ordinary Share for shares to be traded on the LSE's main market and NGN 576 per Ordinary Share for shares to be listed on the Official Trading List of the NSE (the "Offer Price")

Based on the Offer Price, the total market capitalisation of SEPLAT at the commencement of conditional dealings will be approximately £1.14 billion (equivalent to US$1.90 billion) (excluding the exercise of the over- allotment option)

The Global Offer comprises a base offering (the "Base Offer") of 143,284,130 new shares issued by the Company, representing 26.4 per cent of the Company's enlarged issued share capital (excluding the exercise of the over-allotment option)

The Base Offer will raise gross proceeds of approximately £300.9 million (equivalent to US$500 million)

The Over-allotment Option shall consist of 10,336,183 new shares representing 15% of the final amount allocated to investors outside of Nigeria (the "International Offering") in the Base Offer. The Over-allotment Option can be exercised for a period of 30 calendar days from today

The net proceeds of the Global Offer will primarily be used to acquire and develop new acquisitions, and/or pay down any additional debt raised in connection therewith, of both onshore and shallow offshore acreages, assets and joint venture farm-ins. Approximately US$48 million shall be used to pay down in full a shareholder loan from MPI S.A.

The commencement of conditional dealings in the Ordinary Shares on the LSE is expected to occur today at 8 am (London time) under the ticker symbol "SEPL"

Admission of the Ordinary Shares to the Official Trading List of the NSE, under the ticker symbol "SEPLAT", to the Official List of the FCA and to trading on the main market for listed securities of the LSE under the ticker symbol "SEPL" and the commencement of unconditional dealings are expected to take place on or around Monday 14 April 2014

Dr. A.B.C. Bryant Orjiako, Chairman of SEPLAT, said:

"We are delighted with the support shown and happy to welcome a range of blue chip investors to our share register. Despite a challenging market for oil and gas stocks, the response has been excellent and demonstrates strong demand in both London and at home for leading Nigerian indigenous E&P players. I believe our excellent production growth track record, strong cash flow and progressive dividend policy distinguish SEPLAT from many other E&P stocks."

Austin Avuru, Chief Executive Officer of SEPLAT, said:

"We are already a leading indigenous independent in our home market but the opportunities opening up in Nigeria for companies like ours are significant. The proceeds from the Global Offer place us in a strong position to make further acquisitions as the IOCs divest their onshore assets in the Niger Delta. We have a production target of 85,000 barrels of oil and condensate per day by the end of 2016 from our current assets, but our ambition is to secure acquisitions which enable us to exceed this target."
