Hydrocracking/Hydrotreating (MHC/DHT) construction Project Construction of the hydrocracking of VGO/hydrotreating of diesel fractions integrated system creates solutions for the following tasks: Increase in the production of diesel Euro-5 fuel quality due to conversion of VGO. Processing of diesel fractions with high content of S, N compounds, of the unsaturated compounds with low cetane number, to create a high-octane diesel fuel with ultra-low sulfur content. Reduce the costs of constructing a new plant for diesel fuel hydrotreating with a block for de-aromatization of diesel fraction of the catalytic cracking and visbreaking units. The possibility of share of VGO between catalytic cracking and hydrocracking units in accordance with demand for gasoline and diesel fuel. There is a possibility of increasing the conversion of hydrocracking feed from 40% to 50% due to re-circulation of the hydrocracked residue into the process. Facilities, located in the hydrocracking complex, occupy minimum area, but the equipment layout makes it possible to 7 perform remedial works on the equipment at no additional cost.

Development program - Phase 3 In the future Refinery configuration, the feeds that shall be sent to Delayed Coker Unit will be the following: Vacuum Residue from Vacuum Distillation Unit Slurry oil from Fluid Catalytic Cracking Unit. The main products of Delayed Coker will have the following destination: Fuel Gas, to be used inside the unit as fuel for furnaces; the excess of fuel gas can be routed to refinery fuel gas system. LPG, (as mixture of propylene, propane, butylenes and butanes with some impurities like dienes), to be sent to LPG storage after proper treatment (amine washing, caustic treatment, etc..); Coker Naphtha, to be sent to existing Diesel Hydrotreater (DHT), before to be used for gasoline production; Light Coker Gasoil (LCGO) to be sent to existing DHT, before to be used for diesel production; Heavy Coker Gasoil (HCGO) to be sent to Mild Hydrocracking (MHC) as feedstock; The produced coke will be sold on the market as coke fuel grade and a dedicated Coke Handling unit has to be foreseen for coke management. 12 Crude & Vacuum Distillations Crude & Vacuum Distillations Simplified Block Scheme of Delayed Coker addition - Operation Block 1 (100 days/year) S-300 S-4300 MHC S-4400 DHT (*) Naphtha & LCGO DCU Bitumen S-0250 Slurry Heavy Naphtha HCGO Coke (*) Minor Modification foreseen in Stabilizer Section only (*) Minor Modification foreseen in Stabilizer Section only S-2300 FCC S-2450 / S- 4450 SRU UCO Tank UC1 Tank S-2400 Simplified Block Scheme of Delayed Coker addition - Operation Block 2 (230 days/year) S-300 S-4300 MHC S-4400 DHT (*) Naphtha & LCGO DCU Bitumen S-0250 Slurry Heavy Naphtha HCGO Coke S-2300 FCC S-2450 / S- 4450 SRU UCO Tank UC1 Tank S-2400 S-2950 /S- 4950 Amine S-2950 /S- 4950 Amine HCGO Tank RNS Lube New or Revamped Units RNS Lube HCGO Tank New or Revamped Units

Conclusions NIS operating 2 refineries in Serbia, introducing 3-phased investment program, producing already fully EURO quality standard motor fuels (possibly incl. bio-components) and improving impact on environment is recognizable player in the refining industry in the region. NIS recognizing current challengies in front of European and regional refining industry is continuing investment programs for improving its profitability and achieving reduction of quantity of black products, placing on the market most demanded refining derivatives and taking into account that viable refinery should demonstrate the following chracteristics: Capacity suitable to serve respective market to be utilised more than 90% Complexity - NCI>10 operating State-of-the-art technology HSSE standards meeting local requirements and international practices 16
