14 Recent Industry developments Challenging refining environment in the region driven by regional crude supply issues and weak growth • 2013 the worse refining macro backdrop in the Med region for at least a decade • Curtailed supply for crude due to developments in (sanctions), , (internal frictions), Russia (crude directed to the East and domestic refineries) • Weak demand in Europe, particularly in the South due to recession • Competitive advantage of US refineries on energy cost and crude spreads, due to shale oil and gas, led to reversal of product flows across the Atlantic

(*) Calculated as Reported less the Inventory effects and other non-operating items 33 1Q14 HIGHLIGHTS Improved results across all our businesses, as Elefsina contribution and enhanced operational performance offset weak margins and USD

Industry and Market • Med benchmark refining margins significantly lower y-o-y (especially for FCC), with further negative impact due to weaker $; small improvement vs 4Q13 partly due to Brent-Urals spread widening to $0.5-1/bbl area • Uncertainty in Med crude market remains with due to Libya and Iraq exports • Positive signs for domestic fuels demand as auto-fuel remain stable for a 3rd consecutive quarter; 1Q14 GDP estimate at -1.1%, lowest decline in 4 years Financials • 1Q14 Adjusted EBITDA at €51m (+35%), reflecting improved operational performance in all business units, despite weak refining environment and Elefsina 4-week shut-down • Competitiveness projects deliver additional €18m contribution, in line with plan; opex 13% lower y- o-y • Associates contribution at €15m affected by lower gas demand due to mild weather conditions • Net Debt at €2.3bn, driven by operating conditions and seasonality

Business developments • DESFA transaction regulatory approval in process; closing expected in 2014 • New CLA with ELPE refining union agreed for 3 years; annual benefits of c.€10m • Lease agreement for West Patraikos concession signed on 14 May 2014; field studies to commence in 2H14
