Examples of suchforward-looking statements include, but are not limited to, statements regarding exchange rate fluctuations,volume growth, increases in market share, total shareholder return and cost reductions. Words such as "believe","anticipate", expect, "intend", "seek", "will", "plan", "could", "may", "endeavour" and "project" and similarexpressions are intended to identify such forward-looking statements, but are not the exclusive means ofidentifying such statements. By their very nature, forward-looking statements involve inherent risks anduncertainties, both general and specific, and there are risks that the predictions, forecasts, projections and otherforward-looking statements will not be achieved. If one or more of these risks materialise, or should underlyingassumptions prove incorrect, our actual results may differ materially from those anticipated. You shouldunderstand that a number of important factors could cause actual results to differ materially from the plans,objectives, expectations, estimates and intentions expressed in such forward-looking statements. These factorsare discussed more fully in our most recent annual report under the Securities Exchange Act of 1934 on Form 20-F filed on 12 October 2012 and in other filings with the United States Securities and Exchange Commission.

    The Sasol SlurryPhase DistillateTMprocess has threesteps:

    reforming natural gaswith oxygen and steamto produce syngas

    converting syngas intolong-chain waxyhydrocarbons

    Sasol was the first to bringcommercial GTL diesel producedusing low temperature hydrocarbonsynthesis to market on a large scaleand thus required:

    absolute confidence in performance and fit-for-purpose nature of the product (neat and blends)

    Sasols jet fuel story in summary

    Over a period of 20 years Sasol followed an extensive and comprehensiveroute for the qualification of firstly semi-synthetic and later fully synthetic jetfuel engaging all international stakeholders and pioneering the processprotocol.Sasol has more than 13 years experience of commercially producing andmarketing semi-synthetic jet fuel.Sasols fully synthetic jet fuel was approved in April 2008 with thepublication of DEFSTAN 91-91,Issue 6.First passenger flights on Sasols fully synthetic jet fuel in September 2010.Generic GTL approval contained in ASTM D7566 (September 2009).The responsible route that Sasol followed was seen as the benchmark fornewcomers (e.g. the Bio Industry HEFA approval on 5 July 2011).Sasols synthetic Jet Fuel is the only alternative fuel that has beenapproved for commercial use in a neat form.

    Sasol has paved the way for the introductionof GTL fuels in international markets

    GTL diesel has been thoroughly tested in neatform and in blendsIt has been tested in the chemistry laboratory, in avariety of engines in test cells and extensively invehicles on the road.These thorough and detailed investigations haveshown the superior properties of GTL diesel to theworld in over 100 research publications andpresentations.Sasol has led the way in gaining internationalapproval for fully synthetic jet fuel the only fullysynthetic alternative jet fuel.Approval for semi synthetic GTL jet fuel is nowcontained in ASTM D7566Extensive research and testing has shown GTL jetfuel and diesel to be superior products
