2. Shell Norco… A Great Place to Work BACKGROUND – SCOPE & PHASING Chemicals has 41 hydrocarbon (i.e. excludes slop, caustic, additive or process water storage) tanks/spheres/bullets (TSBs) on the “active” register With the advent of a light feed strategy, we anticipate that our end state will have us at 27 TSBs on the “active” register, or a reduction of 34% Areas for reduction include light liquid feed storage (10 to 3), aromatics storage (5 to 2) and LPG storage (13 to 10) There will be three discrete windows that storage assets will be shed (either sold, leased, idled or demolished) from our register – the intent is to front load this plan with the largest assets – Phase 1 – by year end 2009 (X6: F-433, F-498, F-499, F-500, F-501, H-433) – Phase 2 – by August 2010 (X5: F-483, F-494, F-503, F-509, S-404) – Phase 3 – by December 2010 (X3: PV-497, PV-498, PV-499) – Three (out of 5) West Site butylene spheres will also be shed, by the middle of 2010

3. Shell Norco… A Great Place to Work DIRECT IMPACTS ON TANK FARM Routine maintenance, reactive maintenance spend should fall Inspections planned for 2010/2011 that can be deferred indefinitely (until and unless the storage tank in question is justifiably reinstated or sold/leased to another party): 2010: F-494 (1.5 M$), F-499 (2.3 M$), S-404 (0.3 M$) 2011: F-498 (2.3 M$) CAPEX spend for the 14 tanks to be shed should be halted, until and unless the storage tank in question is sold/leased to another party – capital scope changes to Logistics Infrastructure Upgrade project, CUUSA? Total active tank counts drop from 113 to 101, of which Shell Chemical tank counts drop from 41 (36%) to 27 (27%) – a 11% drop in overall assets managed = ? FTE reductions

4. Shell Norco… A Great Place to Work OTHER RELATED IMPACTS Wharf – Careful data-based analysis of Chemicals’ future usage of the wharf should commence shortly – as liquid feedstock shipments should drop correspondingly with liquid feed tank rationalization – Py gas production should also drop as feed diets at GO-1/OL-5 are lightened – less py gas barges to move – BD-5 will be running at minimum rates – may see an uptick in crude and finished BD imports, offset by lower finished BD exports LPG rack – Enterprise has expressed interest in buying the rack, but certain CAPEX provisions are necessary to accomplish turnover Rail rack – In the future, will only be for finished BD sales to local customers + butylene shipments out
