• Increase existing production from Bir Ben Tartar (BBT) and Borj El Khadra (BEK) ü Good potential to increase production during the primary recovery phase ü Drilling rig deployed to BBT in June 2020 – infill wells commencing in Q3 2020 • Continue production and development of the Adam field ü Field to be operated by ENI until 2033 ü Satellite drilling locations • Evaluate and advance onshore discoveries into production ü Many discovery wells are tested and have adjacent production analogues and infrastructure ü New 3D data over onshore undeveloped acreage (6,692 km2) has identified further leads and prospects for drilling, with potential for development of previous untested discoveries • Target 5,000 bopd from onshore assets ü Independent report show the portfolio to be scalable to 18,000 bopd ü With little change to Opex, at 5,000 bopd steady state net free cashflow increases substantially • Progress development of offshore discoveries ü Wells tested with high flow rates: 5,700 bopd/well at Cosmos and 1,200 bopd/well at Yasmin ü Field development plan to be developed for early production • Additional exploration leads and prospects to be evaluated 4 Tunisia – Longstanding Producer

• Government working closely with Industry participants creating an active partnership and streamlined permitting processes • Attractive investment climate drawing new entrants • Active deal flow over the past decade slowed down with low oil prices • Attractive Contractual Terms and scope for expansion through available blocks • Country promoting industry to create jobs • Proven hydrocarbon region • Oil - Priced to Brent, Gas - European prices, export to Europe • Nawara Pipeline near commissioning for 2020 gas sales to market of 2.4MM m3/day, key egress route for non- operated Adam and BEK assets. • Regulatory environment and legal framework supportive • In-country security stable

§ Sirius is building a Pan-African upstream oil and gas platform focusing initially on proven, producing assets that provide solid short-term production growth from low-risk redevelopment activities.

§ Secures a 40% economic interest in the onshore assets and an 80% economic interest in the offshore assets

§ Secures entitlement from the producing Tunisian onshore portfolio.

§ Next stage of growth is provided by a mix of development of appraised assets and low risk exploration on or adjacent to proven onshore licences in Tunisia:

Ø Exploration on Sud Remada (STOIIP 472 mmbbls, surrounds producing BBT field) and Jenein Centre (STOIIP 100 mmbbls+), onshore Tunisia

§ Development of Cosmos and Yasmin discoveries offshore Tunisia

§ Sirius working with funding partners on adding further potential Africa-based producing, development and exploration assets.
