PFOS Working Group Next Steps / Actions from Shanghai Finalize PFOS Joint statement language for 2009 data April 2011 PFOA determination Metrics 5 5

From WSC ESH TF Meeting in Jeju: Current State Individual associations and WSC have effectively reacted to PFOS problem Agreed that WSC should be proactive PFOS WG will use data to evaluate possible strategies for elimination, substitution or control to reduce any ESH impact This would remain only a WSC internal activity at this time The group agreed that most association members are focusing on and continuing to seek elimination of all PFOS uses. Use has decreased to X Regulations and use threats PFAS and PFOA are under study in several regions of the world Scientists have expressed concern that PFOA may exhibit similar ESH impacts as PFOS ISMI has completed industry PFOA/PFAS survey – Use decreased in PFOS/PFOA and increased in C1-C4 PFAS US and EU assessing PFOA use. Likely regulations in some form is expected in the coming years. PFOA need?

PFOS Working Group Objectives Fulfill the elements of the WSC/SEMI Voluntary Agreement for PFOS Continue to monitor important PFOS/PFOA and PFAS developments Develop new strategic directions for perfluoro-chemicals if necessary to address threats Project Update/Next Steps Reviewed actions from Kobe Each association reviewed 2009 PFOS mass balance data Working group reviewed 2009 data for a draft of the aggregated PFOS mass balance template Working group agreed upon elements to be included in the release of information document as an annex to the WSC joint statement to be published in May 2011 Discussed future action of PFOS WG Working group agreed that much of the PFOS Voluntary Agreement work will be complete in 2011 Working group agreed to consider collecting 2010 data to show this work is nearly concluded Discussed regulatory updates on PFOA/PFAS and risk of regulations Working group will consider PFOA/PFAS usage data collection Each region will determine if global PFOA regulation or ban is a concern to IC manufacturing Updated the informal information sharing process Working group agreed to use the template for sharing substance regulatory information proposed by SIA in Europe Discussed proposal for transitioning the PFOS working group into a Chemical Working Group Five of six SIA’s endorse the proposal 8 8

PFOS Working Group PFOS Situation PFOA/PFAS Regulatory Threats Individual associations and WSC have effectively reacted to PFOS problem Agreed that WSC should be proactive PFOS WG will use data to evaluate possible strategies for elimination, substitution or control to reduce any ESH impact This would remain only a WSC internal activity at this time The group agreed that most association members are focusing on and continuing to seek elimination of all PFOS uses PFOA/PFAS Regulatory Threats PFAS and PFOA are under study in several regions of the world Scientists have expressed concern that PFOA may exhibit similar ESH impacts as PFOS EU assessing PFOA use. Likely regulations in some form is expected within the next 2-years. USEPA is considering further regulation of PFOA. USEPA regulation of C1-C4 PFAS seems to be many years in the future. There is the potential for international global regulation for PFOA within the next 5-years.
