4. Methodology Used in Comparative Analysis

5. Proprietary and Confidential © 2013 HSB Solomon Associates LLC www.SolomonOnline.com 5 Methodology Comparison of the performance of the South African oil refineries against  Southeast Asia – Competitive Peers  Western Europe – Similar Age/History of Refineries Average (50 percentile) data used throughout  Note – 50% of the population have performed better than shown Trends shown for four studies – 2006, 2008, 2010, 2012 All comparisons based on US $ as the common currency  However, some indicators may have some minor exchange rate effects South Africa in 2010 has an index of 100

6. Proprietary and Confidential © 2013 HSB Solomon Associates LLC www.SolomonOnline.com 6 Data Preparation Solomon Fuels Comparative Performance Analysis (CPA) Study data from 2006, 2008, 2010, 2012 This data is proprietary to Solomon and is supplied to our clients on the basis that it is not disseminated further without permission  This permission has been given for the SAPIA presentation Solomon does not allow actual study results to be used in a public domain environment As a result, all the following trends have been re-indexed from the study data on the basis that South Africa in 2010 has an index of 100 The relative position of South Africa vs the two Peer Groups is clearly represented

7. Gross Margin

8. Proprietary and Confidential © 2013 HSB Solomon Associates LLC www.SolomonOnline.com 8 Western Europe South Africa Southeast Asia Gross Margin Southeast Asia has had tightening margins as additional capacity has come on line along with low economic growth.

9. Proprietary and Confidential © 2013 HSB Solomon Associates LLC www.SolomonOnline.com 9 Western Europe South Africa Southeast Asia Refinery Configuration Factor Steep increase in Southeast Asia refinery configuration factor due to increased number of high conversion refineries in Peer Group. Less complex refineries are being shut down in Europe.

10. Operational Availability and Utilisation

11. Proprietary and Confidential © 2013 HSB Solomon Associates LLC www.SolomonOnline.com 11 Western Europe South Africa Southeast Asia Operational Availability (Turnaround Duration Annualised + Average of Study Year and Previous Year Downtime) Improving Operational Availability in South Africa is key to improving performance against peer groups.

12. Proprietary and Confidential © 2013 HSB Solomon Associates LLC www.SolomonOnline.com 12 Western Europe South Africa Southeast Asia Process Utilisation (For Study Year Only – With Turnarounds) General increase in Utilisation in 2012 as the world economy recovers from the 2008/2009 downturn and uneconomic refineries are shut down.

13. Operating Costs

14. Proprietary and Confidential © 2013 HSB Solomon Associates LLC www.SolomonOnline.com 14 Western Europe South Africa Southeast Asia Operating Cost Operating Cost driven by energy costs, which tend to be in-line with crude cost, which rose US $30/bbl from 2010 to 2012.

15. Proprietary and Confidential © 2013 HSB Solomon Associates LLC www.SolomonOnline.com 15 Western Europe South Africa Southeast Asia Non-Energy Operating Cost South African refinery Non-Energy Costs driven by higher personnel costs, however 2012 shows little change from 2010.

16. Energy Usage and Costs

17. Proprietary and Confidential © 2013 HSB Solomon Associates LLC www.SolomonOnline.com 17 Western Europe South Africa Southeast Asia Energy Intensity Index (EII) Decline in Southeast Asia EII driven by increased number of modern refineries in Peer Group. Western Europe has improved by 1 EII number per study for the last nine studies.

18. Proprietary and Confidential © 2013 HSB Solomon Associates LLC www.SolomonOnline.com 18 Western Europe South Africa Southeast Asia Energy Cost South African decrease in the energy price for fuel is offset for the most part by a steep increase in imported electricity costs.

20. Maintenance Costs

21. Proprietary and Confidential © 2013 HSB Solomon Associates LLC www.SolomonOnline.com 21 Western Europe South Africa Southeast Asia Maintenance Cost (Labour + Materials) Solomon studies show a strong relationship between maintenance costs and operational availability—poor operational availability usually results in high maintenance costs, however South African costs are driven by cost of labour.
