3 Rockhopper Corporate Overview

§ Our strategy is to create value through building a well-funded, full-cycle, exploraon led E&P company

§ We aim to do this by:

§ Maintaining balance sheet strength and flexibility

§ Building a balanced porolio of assets in our core geographical areas of the North NORTH FALKLANDS BASIN Falkland Basin and the Mediterranean / North African region

§ Leveraging our technical skill set to target value accreve exploraon in proven hydrocarbon basins

§ Exploration well to look for additional prospectivity in licence, 14/10-8 testing Casper SLMC and Kermit in optimal location that penetrated all three reservoirs

§ Step out to south in new fast track data area to expand proven 14/10-9 discovery area, to test reservoir continuity and presence of SL10 and SL20 as stacked fans in location above the OWC

§ Significant step out to test SL10 at its southern extension and to 14/15-4 test presence of Beverley and Casper South

§ Near field low risk, high resource exploraon well, 3.4km from 14/15-4

§ 7 stacked targets with varying GCoS of 9-52%

§ Risking lowest for F2 Zebedee fan

§ Net prospecve Pmean resource 68mmbbls (range 13-178)

§ Extension of proven Sea Lion fan play

Spectral Decomposion at F2 level

25 PL04a Isobel Deep, RKH WI 24% § High impact moderate risk (GCoS 20%) exploraon well with potenal to open new Isobel / Elaine development area (32km from 14/15-4)

§ First test of F3 fan system entering basin from the south-east margin as a sequence of offset stacked reservoirs. Fans developed in heart of mature source kitchen.

§ Complex as whole mapped to have gross Pmean resources of 510mmbbls (range 80 – 1424mmbbls)

§ First well (Isobel deep) to targets core of Isobel deep fan in area of maximum mapped reservoir thickness

§ Potenal appraisal locaon idenfied

26 PL04c Jayne East, RKH 24% WI § Test proven reservoirs of Beverley and Casper South on the eastern flank of syncline

§ Total of 5 reservoirs targeted in locaon proximal to sediment source

§ Excellent reservoir quality ancipated in F2 sands

§ Two deeper F3 exploraon targets intersected which require separate deeper hydrocarbon column

§ Gross Pmean mapped resources of 87mmbbls (range 21-214mmbbls)

§ Close proximity to Sea Lion development area

Spectral Decomposion at F3G level

27 PL032 Chatham, RKH WI 40% § Well will confirm presence or absence of non-equilibrium gas cap on western flank of Sea Lion

§ 50% chance of gas cap being absent and oil filled, adding c.65mmbbls to Sea Lion resources

§ Deeper Chatham exploraon target (GCoS 17%) tesng deltaic fed channel/ fan system entering basin from north.

§ Play opening target for other idenfied northerly fed systems

§ If successful would be accessible from a phase 1b development

Spectral Decomposion at F3A level

28 Exploraon & Impact on Sea Lion Development Phases

• Phase 1a development concept is independent of outcome of 2015 exploraon programme

• Phase 1b has potenal upside in PL032 in event that Chatham / gas cap well is successful

• Phase 2 development concept will be determined by the materiality of the success of the 2015 exploraon campaign

• Success at Isobel expands development area significantly
