Executive Summary

Acquisition of E.ON’s UK North Sea assets completed On-going asset disposals

2016 – progress against targets

On track to deliver at or above upper end of FY guidance of 65-70 kboepd 88% operating efficiency in Q1

Opex tracking 10-20% below budget; expected FY opex of c. $17/boe Gross G&A on track to deliver 10% reduction on 2015 (ex E.ON)

Solan on-stream 12 April, >14 kboepd tested from P1 P2 expected on-stream by mid-year

Pre-first oil capex 15% lower at $1.35 bn; first oil on schedule for 2017 FPSO delivery to Singapore by July; targeting subsea work completion by Q4

Net debt of $2.68 bn at end April; 2016 capex spend front-end loaded Expect to be cash flow positive at oil prices above c. $50/boe in Q4

Discussions ongoing with lenders to secure financial covenant waiver if required

Focus on Advantaged Assets

• UK, SE Asia, Falklands • Disposal of non-core assets • Appropriate balance of current cash flow,

development projects and longer-term upside

Looking forward

Strategy

Accelerate Debt Reduction • Take necessary corporate actions to

minimise net investment in 2016 (as in 2015)

• 2017 will see de-leveraging at the current forward curve

Continue Focus on Cost Base • Further opex and G&A savings in 2016 • Current and future capex spend

reductions

Looking forward

Proven Track Record in Acquisitions/Divestment • 6 separate transactions since 2013, focused on

pre-development assets • E.ON portfolio added 70 mmboe at cost of <$2/bbl;

offers further opportunities for asset disposal

Portfolio Management

Quality 2019 Portfolio • 80-90 kboepd; $15/bbl opex; long life

assets • Balance sheet debt reducing rapidly

Highly leveraged to oil price recovery • Low cash cost base; low effective

tax rate • Costs re-set to a sub-$50 world • c. 850 mmboe of reserves and

resources

Final Investment Decision Timing

Will remain dependent on:

• Achieving attractive rates of return

• The outlook for long term oil prices

• The level of cost reductions secured

• Premier’s ability to fund project – without risking the balance sheet

Sea Lion complex – low cost option for large future value

• Phase 1 project economics enhanced

– 220 mmbbls from NE & NW areas of PL032

– 18 wells (13 pre-drilled) and 20 year field life

– $1.8 bn capex to first oil unchanged (costs down 30%)

• Conceptual design work completed

• Draft FDP submitted to FIG for comment

• Completed SPA amendment with RKH

• Phase 1 FEED is progressing cautiously

• Anticipate securing further cost reductions

• Looking to bring in additional upstream partner

North Falklands Basin – potential confirmed

Successful exploration programme now complete

• Zebedee discovery proves up additional resource to northern North Falklands Basin development

– Adds c. 60 mmbls resource to Sea Lion Phase 2

• Isobel Complex potential confirmed

– Potential for >480m oil column

– Multiple additional oil-bearing sands

• Programme curtailed due to rig performance issues

• Further appraisal concurrent with Sea Lion development

Covenant compliance and mitigating actions

• E.ON UK asset acquisition materially covenant accretive

4.

• Covenant position amended – Net debt $2.2 billion (YE 2015) – Headroom > $900m (YE 2015) – Strong support from banks & bondholders

1.

• Key focus on compliance in low oil price environment

– Tested half yearly at 30 June and 31 Dec – Likely to require relaxation of covenants if

low oil price persists

2.

• Mitigating actions – Capex phasing, pre-paid oil sales, further

cost reductions, sale and leaseback, asset disposals

3.

Appendix

Rationale for the E.ON acquisition

• Strengthens Premier’s position in UK North Sea with its associated tax benefits; opportunity to generate operating and cost synergies

• Continues Premier’s track record of capturing long term value through acquisition at low points in the oil price cycle

• Adds stable UK gas revenues to the portfolio; rebalancing commodity exposure

• Adds high quality assets at a compelling valuation with a valuable hedging position in 2016 and 2017

– Assets acquired at $1.6/boe based on CPR estimate of 2P reserves vs. UK North Sea average of $13/boe (since 2000)

– CPR values the net asset value of 2P reserves and SNS infrastructure at $494 million (pre-tax) vs. purchase consideration of $120m

• Adds immediate cash generative production, tax synergies and material covenant accretion with rapid payback – meeting Premier’s stated acquisition criteria

• Acquired with a valuable hedging portfolio in 2016 and 2017 – 2016: 32% estimated gas production @ 63p/therm, 33% estimated liquids production

@ $97/bbl – 2017: 21% estimated gas production @ 57p/therm

• Significant benefit to covenants (Net Debt to EBITDAX) at 30 June 2016 and 31 Dec 2016

• Expected payback of around 2 years, sooner if potential disposal of assets

• Sharing of liabilites with seller on Ravenspurn North & Johnston • c.£250m of historic tax paid off-settable against future decommissioning

• Adds significant cash flow in 2016 and 2017 even at current oil/gas prices – c.15mboepd of net production and associated cash flow added on completion – YTD production ahead of forecast
