You may submit your concern anonymously or confidentially by postal mail. You may also indicate whether you are a shareholder, customer, supplier, or other interested party.

Communications are distributed to the Board, or to any individual directors as appropriate, depending on the facts and circumstances outlined in the communication. In that regard, the Sigma-Aldrich Corporation board of directors has decided that certain items which are unrelated to the duties and responsibilities of the board will not be reviewed through this process and instead will be given to Management to resolve. Topics include:

• Product complaints
• Product inquiries
• New product suggestions
• Resumes and other forms of job inquiries
• Surveys
• Business solicitations or advertisements

In addition, material that is unduly hostile, threatening, illegal or similarly unsuitable will be excluded, with the provision that any communication that is filtered out must be made available to any non-management director upon request.

You may also communicate online with our Board of Directors as a group.
