•Industry pricing environment has improved through:

–Net capacity reductions of about 12% since 2000

–We expect the tight caustic market to continue which
should provide a positive pricing environment into first
half of 2009; the result of low chlor alkali industry
operating rates due to soft vinyls demand

–European imports into the East Coast are similar to 2007
levels while West Coast imports from China have
increased over 2007 levels, a trend that is expected to
continue at a similar rate

* ECU Netback = ECU price - freight +/- customer premiums/discounts

ECU Netback* Environment

14

Olin ECU Netback Outlook

•Caustic price announcements totaling $620 per ECU
through Q3 are supported by tight caustic supply and are
expected to be realized in Q4 and into 2009

•Q3 ECU netback of $660 is 12% higher than Q2; we
expect sequentially higher netbacks into the 1H 2009

•Higher ECU netbacks are driven by caustic pricing
offsetting lower chlorine prices and higher freight costs:
