2010 highlights

  • On track for production of 75,000 boepd in 2012
  • Development portfolio building towards

100,000 boepd in 2014

  • 8 out of 14 exploration and appraisal wells

successful

  • Operating cashflow up 25% to $436.0 million
  • Record profits after tax of $129.8 million
  • $1.1 billion of UK tax allowances - mitigating the

impact of proposed tax changes

  • Cash and undrawn bank facilities of $1.2 billion

Building three quality E&P businesses

Strategy

  • Grow near-term production to

75 kboepd from existing 2P reserves of 261 mmboe

  • Deliver further growth by

commercialising contingent resource base of 228 mmboe

  • Add 200 mmboe through

exploration by focusing on core geologies

  • Make value-adding acquisitions

in three core areas

  • Maintain a conservative

financing plan

Creating an overall business with 400 mmboe of reserves and 100 kboepd production in the medium term

Commercial Arrangements

  • Premier and Chrysaor signed MoU on 16 March 2011
  • Premier will participate in the development with a 60% equity
  • Premier will provide Chrysaor with a bridging loan to fund their remaining project costs
  • Chrysaor will repay the loan via a cash sweep to Premier of a share of their revenue
  • Operatorship arrangements still to be discussed
  • Intention is to sign a full SPA by mid April

Hedging

  • Policy unchanged: secure cashflows via floors or

forwards to fund investment programme even at low oil prices

  • 2010 Impact

– Income statement gain of $39 million as past provisions unwind – Cash cost of $8 million on maturing hedges Outlook

  • Approximately 26% of forecast liquids production for

2011/12 capped at average of $87

  • Approximately 19% of forecast gas production from

Indonesia for 2011/12 and 1H 2013 is capped at $500 / MT

  • Future hedging plans will depend on development

programme requirements relative to cashflow
